Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, an indication that indicates whether a multicast and broadcast service (MBS) physical downlink shared channel (PDSCH) scheduled by downlink control information (DCI) is associated with a second PDSCH processing capability, wherein the second PDSCH processing capability has a shorter duration than a first PDSCH processing capability. The UE may receive, from the base station, the MBS PDSCH scheduled by the DCI. The UE may transmit, to the base station and based at least in part on the indication, hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback in accordance with the first PDSCH processing capability or the second PDSCH processing capability. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may monitor a set of time-frequency resources for one or more cell detection signals (CDS) associated with a pseudo-random sequence, where the pseudo-random sequence and the set of time-frequency resources are indicated by an output of a pseudo-random function (PRF) that is based on a timing parameter, a cell identifier (ID), and a shared key. Accordingly, the UE may communicate with a network entity via a cell associated with the cell ID based on receiving the one or more CDS. The UE may also exchange one or more messages with the network entity, and may perform a time calibration procedure based on the one or more messages and a delay threshold of the UE. The one or more messages may indicate an ID of the UE, a cryptographic number, a time interval, or a combination thereof.

Abstract: Methods, systems, and devices for wireless communications are described. A method for wireless communication at a user equipment (UE) may include: receiving a multicast bandwidth part configuration for multicast communications between a base station and the UE, where the multicast bandwidth part configuration includes a maximum number of multiple-input, multiple-output layers to be used for the multicast communications; establishing a multicast link with the base station for multicast communications; determining to use a reduced number of antennas for multicast reception than the number of antennas used for unicast reception, or determining that the UE is able to decode the multicast communications prior to a remaining portion of the multicast communications; and receiving the multicast communications via the reduced number of antennas, or reducing the radio frequency power prior to completion of a number of repetitions or retransmissions of the multicast communications.

Abstract: The present disclosure relates to transmitting and receiving a group wake-up signal (WUS) in conjunction with an ungrouped WUS. A base station may group one or more UEs in a UE group, while other UEs may not be assigned to a UE group. The configuration of WUS resources and WUS sequences for grouped UEs and other UEs is a challenge. The base station may transmit, to one or more UEs in the UE group, a resource allocation of a group WUS resource within a set of WUS resources associated with a paging occasion that is assigned to the one or more UEs in the UE group. A UE, after receiving the resource allocation, may determine a location of the group WUS resource within the set of WUS resources. The UE may monitor for a group WUS at the determined location in the resource allocation of the group WUS resource.

Abstract: A method for wireless communication performed by a user equipment (UE) includes receiving, from a base station on a granting group common (GC)-physical downlink control channel (PDCCH), a multimedia broadcast multicast service (MBMS) downlink grant that schedules an MBMS transmission at each UE of a group of UEs that includes the UE. The method also includes receiving, from the base station on a triggering GC-PDCCH, a message indicating respective feedback resources for each UE of the group of UEs. The method further includes receiving, from the base station, the MBMS transmission. The method still further includes transmitting, to the base station via the feedback resources, a feedback report based on receiving the MBMS transmission.

Abstract: Aspects directed towards sounding reference signal (SRS) antenna switching are disclosed. In one example, an SRS configuration is received from a network in which at least four antennas of a scheduled entity are configured based on the SRS configuration. Here, the SRS configuration configures at least one antenna to simultaneously support SRS antenna switching and an uplink (UL) multiple-input multiple-output (MIMO) communication. An SRS communication is then transmitted according to the SRS configuration. In another example, a transmission capability reporting is received from a scheduled entity comprising at least four antennas. A determination is then made of whether the scheduled entity may simultaneously support SRS antenna switching and an UL MIMO communication. An SRS configuration is then generated for the scheduled entity based on the determination in which a default SRS configuration configures at least one antenna to simultaneously support the SRS antenna switching and the UL MIMO communication.

Abstract: Methods, systems, and devices for wireless communications are described. A receiving device may use enhanced techniques for determining whether a transmission is scheduled to include new data when a mode for reporting acknowledgment feedback is disabled for one or more hybrid automatic repeat request (HARQ) processes used by the receiving device. An enhanced technique may include increasing a quantity of bits used to convey an indication of whether a scheduled data transmission includes new data. An enhanced technique may include monitoring a duration between transmissions scheduled by different control messages based on a timing parameter that indicates a maximum time between transmissions of a data set and corresponding transmission including the data set.

Abstract: A base station may transmit a multicast transmission to a group of user equipments (UEs) that are each configured with a group radio network temporary identifier (G-RNTI). The UEs may be configured to receive the transmission using the same modulation and coding scheme (MCS) and transport block size (TBS) such that the group of UEs may receive the same transmission. In particular, a UE may receive one or more configurations for multicast transmissions, each configuration associated with a G-RNTI. The UE may determine a MCS table for the G-RNTI. The UE may determine a TBS for a multicast transmission based on an overhead value for the G-RNTI. The UE may receive the multicast transmission based on the MCS table and the TBS.

Abstract: A method of wireless communication by a user equipment (UE) calculates a propagation delay for sending a message from the UE to a network node, such as a base station, via non-terrestrial communications. The method sends a random access preamble to the base station while accounting for the calculated propagation delay. The method starts a random access response (RAR) window at a first physical downlink control channel (PDCCH) occasion after twice the calculated propagation delay from sending the random access preamble. The method receives a random access response (RAR) message from the base station during the RAR window. The RAR message includes an uplink grant indicating an uplink shared channel resource. Further, the method sends an uplink message to arrive during the uplink shared channel resource while accounting for the calculated propagation delay.

Abstract: Methods, systems, and devices for wireless communications are described. Described techniques provide for mitigating error in time or frequency adjustments for preambles of a random access procedure. A user equipment may use one value for the adjustment when transmitting data to a non-terrestrial network, but then transmit the preamble of a random access procedure according to a preamble-specific time or frequency adjustment based on one or more indications received from the network (e.g., rather than resetting the adjustment to “0”). By using some signaled value for the preamble-specific timing or frequency adjustment rather than resetting the adjustment to “0,” preamble reception performance may be maintained or improved with as many or fewer position measurements for the UE or non-terrestrial network entity.
