Abstract: Methods, systems, and devices for wireless communications are described for allocating additional random access channel (RACH) resources. A user equipment (UE) may transmit a random access request to a base station. The base station may respond to the random access request with a random access response or other signaling that indicates additional RACH resources for a second random access request. The UE may select a resource from the additional RACH resources to transmit the second random access request. The network may also configure additional RACH resources for peak times and may indicate the additional RACH resources to the UE. The UE may select a resource from the additional RACH resources or baseline RACH resources and may use the selected resource to transmit a random access request.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently facilitating acknowledgment (ACK) or negative acknowledgment (NACK) feedback from a user equipment (UE) for a set of transport blocks in one or more multicast transmissions from a base station. The UE may determine control channel resources for transmitting the ACK/NACK feedback, and each respective control channel resource may correspond to a distinct subset of the set of transport blocks. Once the UE determines a subset of transport blocks that the UE failed to decode (such as at least one transport block), the UE may determine a respective control channel resource that corresponds to the at least one transport block that the UE failed to decode. The UE may transmit ACK/NACK feedback on the respective control channel resource, which, in some examples, may indicate that the UE failed to decode the subset of transport blocks.

Abstract: A wakeup signal (WUS) group that may be divided into WUS sub-groups, criteria or metrics for dividing the WUS group into a set of WUS sub-groups, and signaling or messaging to support the division of the WUS group into the set of WUS sub-groups are provided. For example, a set of UEs may be divided into WUS sub-groups based at least in part on respective frequencies of occurrence of paging occasions for the set of UEs (e.g., based at least in part on traffic type, observations regarding past paging occasions, predictions regarding future paging occasions, and/or the like) and/or based at least in part on other considerations. Furthermore, some techniques and apparatuses described herein provide for the mapping of network device-level WUS sub-groups (e.g., supported by a network device such as an MME) to base station-level WUS sub-groups (e.g., supported by a base station).

Abstract: In methods, systems, and devices for wireless communications are described, a user equipment (UE) may receive a downlink control information (DCI) block including DCI for a set of transport blocks scheduled for the UE, the DCI including a set of fields. The UE may decode the DCI block to obtain the DCI for the set of transport blocks, where at least two fields of the downlink control information are jointly decoded according to an encoding scheme, and where each possible output of the encoding scheme corresponds to a jointly valid combination of the at least two fields. The UE may receive the set of transport blocks from a base station based on the DCI.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and a base station may communicate in a wireless communications system. The UE may receive first control signaling indicating a first radio network temporary identifier (RNTI) and a first feedback process identifier, where the first RNTI indicates scheduling of a unicast downlink transmission. The UE may also receive second control signaling indicating a second RNTI and a second feedback process identifier, where the second RNTI indicates scheduling of a multicast downlink transmission. The UE may manage a hybrid automatic repeat request (HARM) process at the UE associated with the unicast downlink transmission and the multicast downlink transmission based on the first RNTI, the first feedback process identifier, the second RNTI, and the second feedback process identifier. The UE may also simultaneously process multicast downlink transmission and broadcast signaling.

Abstract: A resynchronization signal (RSS) may extend across multiple physical resource blocks (PRBs) or subframes, which may cause the RRS to be scheduled to overlap with other downlink transmissions. Methods, systems, and devices for wireless communications are described for management of RSS and one or more other transmission types that may have overlapping wireless resources with the RSS. If one or more other downlink transmissions are scheduled for resources that overlap with resources scheduled for an RSS transmission, the UE may receive the RSS transmission or the one or more other downlink transmissions, or a combination thereof, based on a prioritization of the transmission types of the one or more other downlink transmissions relative to RSS. The RSS transmission or the one or more other transmissions may be delayed, dropped, punctured, or rate-matched when the RSS transmission and the one or more other downlink transmissions conflict.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may determine a transmission beam configuration for transmitting multicast data to a user equipment (UE) in a joint transmission using a set of transmission/reception points (TRPs) based on outcomes of listen before talk (LBT) procedures performed at the TRPs. In some examples, the base station may indicate to the UE that the UE is to determine a UE beam configuration and a quasi co-location (QCL) relationship associated with the TRPs for receiving the multicast data based on signaling from the TRPs. In some examples, the base station may transmit multicast data from a first TRP (e.g., a serving cell) during a first transmission opportunity (TxOP), and the UE may determine the QCL relationship for the set of TRPs. During a second TxOP, the base station may transmit multicast data in a joint transmission from the set of TRPs.

Abstract: Methods, systems, and devices for wireless communications are described. In some cases, devices such as band limited (BL) or coverage enhancement (CE) user equipment (UE) having limited transmitting and receiving capability may operate using a subset of a system bandwidth of a carrier (e.g., narrowbands). To support frequency hopping or frequency diversity in transmissions, for example, such devices may utilize retuning when a resource allocation moves from a first narrowband to a second narrowband. Retuning, however, may create challenges when transmitting and receiving capability is limited. Aspects of this disclosure may support a flexible starting physical resource block (PRB) for indicating new resource allocations for BL or CE UEs. In some aspects, a UE is disclosed which may retune between consecutive transmission time intervals (TTIs) or subframes, for example, from a first tuning band to a second tuning band (e.g., a newly defined retuning narrowband).

Abstract: Some techniques and apparatuses described herein provide for the determination of a gap for a scheduled communication involving multiple, different TBs. For example, some techniques and apparatuses described herein provide for the determination of a gap between two or more PDSCHs that are scheduled by a same DCI based at least in part on a UE capability, such as a processing time or a processing mode. Some techniques and apparatuses described herein provide for the determination of a gap between a last PDSCH and a next PDCCH based at least in part on the UE capability. The gap(s) may permit the UE to successfully receive and/or decode multiple PDSCHs and/or PDCCHs in view of the limitations imposed by the UE's processing time or processing mode. In this way, efficiency of PDSCH/PDCCH resource utilization may be improved, the likelihood of a failed PDCCH transmission is reduced, and network efficiency is improved.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured with a set of parameters to determine a valid timing advance (TA) to transmit data using preconfigured uplink resources (PUR) during an idle or inactive mode. In some cases, the parameters are one or more TA commands and one or more conditions associated with each TA command. The UE may identify the current condition of the UE and determine whether the current condition of the UE matches one of indicated conditions. The UE may select a TA command based on finding a match and use the TA command to transmit an uplink PUR transmission. Additionally or alternatively, the parameters may be neural network parameters that indicate a neural network model that the UE may use to determine a TA command associated with a valid TA based on the current condition of the UE.
