Abstract: A user equipment (UE) may initiate a Type-1 or Type-2 random access procedure from a power saving mode, generate a channel state information (CSI) report and a buffer status report, and selectively multiplex the CSI report and BSR with mobile originated (MO) data in a random-access message of the random-access procedure. The UE may further transmit a request to remain in the power saving mode after finishing the transmission of the MO data. The configuration of random access and CSI reporting procedure depends on the UE type or UE capability supported by the network.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine a downlink configuration including a set of resources for receiving downlink transmissions. The UE may determine, based on the downlink configuration, an uplink configuration including a set of resources for transmitting scheduling requests at a set of scheduling request occasions. In some aspects, the set of scheduling request occasions may be arranged according to a non-uniform spacing pattern in the time domain. The UE may transmit, to a base station, one or more scheduling requests based on the uplink configuration.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may obtain updated location information, and determine a time difference between a previous communication with a network and a scheduled uplink transmission. Based on the determined time difference, the UE may determine a timing advance (TA) component of a TA value to apply for the uplink transmission, and transmit an uplink message in the uplink transmission according to the determined TA value and the location information. In some examples, the time difference may be based on a first duration between the uplink transmission and a previous uplink transmission, a second duration between the uplink transmission and a previous TA command received from the network, or both. In some examples, the determined TA value may be based on additional parameters, such as an autonomous adjustment step, an aggregate adjustment rate, a scaling factor, or any combination thereof.

Abstract: Techniques and apparatus for intra-frequency measurement of Layer 3 (L3)-based channel state information reference signals (CSI-RSs) are described. An example method that may be performed by a user equipment (UE) includes transmitting an indication based on a UE capability to simultaneously receive downlink data from a serving cell on one or more first resources and measure one or more CSI-RSs from a target cell on one or more second resources. The one or more first resources at least partially overlap the one or more second resources in a time domain and a frequency domain. The method also includes performing a CSI-RS measurement procedure, based on the UE capability.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive downlink control information that schedules a paging message, wherein the downlink control information indicates whether a UE group associated with the UE is paged in the paging message. The UE may determine whether to decode the paging message based at least in part on the downlink control information that indicates whether the UE group associated with the UE is paged in the paging message. Numerous other aspects are provided.

Abstract: Apparatus, methods, and computer-readable media for managing HARQ-ACK processes in wireless user equipment (UEs) allow selective compression of HARQ-ACK information within HARQ-ACK codebooks. A wireless base station may transmit control information including scheduling information for K downlink transport blocks for a UE, and may signal bundling rules for selectively compressing an original HARQ-ACK codebook of size K into a constrained HARQ-ACK codebook of size N

Abstract: Methods, systems, and devices for wireless communication are described. In some systems, a network entity may transmit, to a user equipment (UE), scheduling information that allocates multiple uplink channels of a same channel type to the UE. The scheduling information may indicate respective sets of frequency resources for each of the uplink channels. The network entity may transmit an indication that uplink channel selection by the UE is enabled. The UE may select a first uplink channel from the multiple uplink channels allocated by the scheduling information based on the indication that uplink shared channel selection is enabled. The UE may transmit an uplink message via the first uplink channel, and the UE may refrain from transmitting via other uplink channels of the multiple uplink channels allocated by the scheduling information based on selecting the first uplink channel.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine that there is a duplex mode conflict among control resource sets (CORESETs), among search space (SS) sets, or among one or more CORESETs and one or more SS sets, select a duplex mode based at least in part on one or more conflict rules after determining that there is a duplex mode conflict, and communicate with a base station using the duplex mode. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit uplink transmissions according to a frequency hopping pattern. The UE may identify that a first set of uplink transmissions are to be transmitted to a base station by a first set of resources (e.g., a first set of slots, a first set of frequency resources) as indicated by the frequency hopping pattern. The UE may further identify, based on the frequency hopping pattern, that a second set of uplink transmissions are to be transmitted to the base station by a second set of resources (e.g., a second set of slots, a second set of frequency resources). The first set of slots and the second set of slots may each include more than one slot. Additionally, the first and second set of resources may be within a same bandwidth part or in different bandwidth parts.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit downlink control information (DCI) to a user equipment (UE) indicating a joint field for at least a first component carrier (CC) and a second CC of a carrier aggregation configuration. For example, the joint field may include a rate matching (RM) indication for the first CC and the second CC, a zero power channel state information reference signal (ZP-CSI-RS) indication for the first CC and the second CC, or both. In some cases, the RM indication may include a common RM resource (RMR) configuration applicable for both the first CC and the second CC or per-CC RMR configurations that indicate separate RMRs for each of the CCs. Additionally, the ZP-CSI-RS indication may include a set identifier that indicates a resource set for ZP-CSI-RS resources for both the first CC and the second CC.
