Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a multicast channel configuration that indicates a set of multicast channel time domain resources allocated to a multicast channel for a first multicast broadcast area. The UE may receive an indication of a first set of time domain resources, of the set of multicast channel time domain resources, that have a first reference signal pattern that differs in frequency domain density as compared to a second reference signal pattern used for at least one of a second set of time domain resources of the set of multicast channel time domain resources or a second multicast broadcast area. The UE may decode the first set of time domain resources based at least in part on the first reference signal pattern. Numerous other aspects are provided.

Abstract: Disclosed are apparatuses and techniques for wireless communications. In an aspect, path information from a plurality of relays is received at a server. A relay cell list for an area of interest is compiled based on the received path information from the plurality of relays. The relay cell list is provided to a user equipment (UE). The UE can use the relay list to assist in the search and/or selection of relays in the wireless communications network.

Abstract: A base station maps code blocks of a transport block of a transport block size (TBS) for a channel using tone-level interleaving or resource element (RE)-level interleaving. Then, the base station can transmit the code blocks of the transport block of the TBS for the channel. A UE may receive the channel from the base station and de-interleave the received tones of the channel in a frequency domain to obtain the code blocks of the transport block having the TBS for the channel.

Abstract: A method, an apparatus, a base station, a user equipment (UE), and a computer program product for wireless communication are provided. The base station may encode a wakeup signal so that a preamble of the wakeup signal indicates whether the wakeup signal is relevant to the UE. The UE may select a technique for detecting the wakeup signal based at least in part on a partial, full, or no synchronization. In some aspects, the wakeup signal may be encoded with a system frame number. In some aspects, wakeup signals for guardband/standalone UEs are provided. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may signal, to a base station, a capability of the UE relating to carrier aggregation for a particular category or class of the UE, such as for narrowband Internet of Things (NB-IoT) UEs. The UE may receive, from the base station, a configuration for carrier aggregation for the particular category or class of the UE based at least in part on the capability of the UE relating to carrier aggregation for the particular category or class of the UE. The UE may communicate with the base station using carrier aggregation based at least in part on the configuration for carrier aggregation for the particular category or class of the UE. Numerous other aspects are provided.

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: Certain aspects of the present disclosure relate to techniques for sounding reference signal (SRS) transmission in multiple SRS symbols in a subframe based on multiple SRS configurations, including determining for each of the multiple symbols a SRS pattern index. In some examples, the present disclosure provides a method of wireless communication by a user equipment (UE). In certain aspects, the method includes receiving, from a base station, information corresponding to a plurality of SRS configurations for a subframe, and determining a plurality of symbols in the subframe for transmitting SRS based on the plurality of SRS configurations.

Abstract: A method, a computer-readable medium, and an apparatus are provided for wireless communication at a User Equipment (UE). The UE receives a second random access message from the base station after transmitting a first random access message. The second random access message comprises a random access response (RAR) that indicates a narrowband to be used for receiving a fourth random access message. The apparatus determines whether to perform a measurement of the narrowband for the fourth random access message based on an amount of time between receiving the second random access message and transmitting a third random access message. The base station may determine whether the report comprises a measurement of the first narrowband or the second narrowband based on an amount of time between the second random access message and the third random access message or based on an indication in the third random access message.

Abstract: In an example, a method of wireless communication of a base station may include assigning, by the base station, one or more resources to a group comprising a plurality of UEs that includes a first UE. The method may include receiving, by the base station from the first UE, a message on the one or more assigned resources. The message may include a cyclic redundancy check (CRC) scrambled with a group identifier for the group comprising the plurality of UEs. The message may include an indication of a UE identifier for the first UE within the group. The message may include a DMRS, where the indication of the UE identifier is represented by a sequence of the DMRS.
