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.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a notification of a change to multicast broadcast (MB) control information associated with at least one MB service to which the UE is subscribed, the MB control information being included in an MB control channel (MBCCH) scheduled by a physical downlink control channel (PDCCH) communication addressed to an MB radio network temporary identifier (MB-RNTI); and monitor one or more resources of the MBCCH to receive updated MB control information based at least in part on receiving the notification of the change to the MB control information. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit multiple repetitions of a paging early indication (PEI) signal to a user equipment (UE) to indicate that the UE is to receive paging signaling in a paging occasion. In some cases, a PEI occasion for transmitting a PEI repetition may have a scheduling conflict. For example, a PEI occasion may collide with other downlink signaling. A UE may implement techniques to resolve scheduling conflicts or collisions for PEI repetitions. For example, the UE may be configured to receive either colliding PEI signaling or colliding downlink signaling based on priorities of the signaling. Additionally, or alternatively, PEI signaling may be shifted (e.g., delayed) until after the downlink signaling ends. In some cases, a UE may be configured with a subset of blind decoding hypotheses for PEI decoding.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support mechanisms for determining a transmit power of a paging early indication (PEI) transmission. In particular, a user equipment (UE) receives a PEI from a base station indicating whether the UE is being paged during a paging occasion. The UE determines a transmit power of the PEI transmission. In some aspects, the UE determines the transmit power of the PEI transmission based on a configuration of the PEI provided to the UE, which may include an indication of the PEI transmission power as an absolute power value and/or a power offset value with respect to another transmission, signal, or channel. In some aspects, the transmit power of the PEI transmission is based on whether the PEI transmission is a beamformed transmission.

Abstract: Various aspects provide a method for radio resource allocation to support multicast services from a 5G-NR base station. In some aspects, the method may be performed by a processor of the base station. Various aspects include determining a multicast bandwidth part (BWP) within a carrier bandwidth, sending an indication of the multicast BWP to one or more user equipment (UE) computing devices in communication with the base station, and scheduling transmission of multicast data in the multicast BWP.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit a downlink control information (DCI) message to one or more user equipments (UEs) scheduling a multicast data message in a multicast downlink shared channel, the DCI message indicating a feedback process identifier (ID) for the multicast data message. The base station may transmit an additional DCI message to a UE scheduling a retransmission of the multicast data message in a unicast downlink shared channel and indicating a feedback process ID for the retransmission of the multicast data message. The feedback process ID for the retransmission may be the same as, or different from, the initial transmission of the multicast data message. The UE may transmit feedback for the multicast data message based on receiving the initial transmission of the multicast data or the retransmission of the multicast data and the feedback process IDs.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a base station may transmit system information indicating multiple multicast-broadcast network areas, and may further provide configuration information for each multicast-broadcast network area indicating a location of multicast scheduling information (MSI). The MSI may include an indication of frequency resources on which to receive broadcast or multicast services. The MSI may indicate specific services for an multicast-broadcast network area that are provided via the different frequency resources (for example, different cells, carriers, channels, among other examples). In some examples, the base station may schedule broadcast or multicast services across frequency resources via semi-persistent scheduling. The MSI may indicate a redundancy version configuration (for example, time and frequency patterns for combined redundancy version broadcast transmissions).
