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: Methods, systems, and devices for wireless communications are described. Transport blocks may be scheduled using a single downlink control information (DCI) message. A wireless device may identify mapping pattern for mapping the transport blocks and repetitions of the transport blocks to communication resources. Mapping the transport blocks, or determining a mapping of the transport blocks, to communication resources may include partitioning the communication resources into subunits, where each subunit includes resources spread across each subband of a frequency hopping pattern and at least one instance of each of the scheduled transport blocks.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, such as a user equipment (UE) may monitor a pre-wakeup window during an inactive duration of a multicast discontinuous reception (DRX) cycle that includes multiple active durations and multiple inactive durations. The UE may receive, in the pre-wakeup window, a wakeup signal that indicates a quantity of the active durations in the multicast DRX cycle that the UE is to monitor and the UE may monitor the indicated quantity of active durations for multicast signals for the UE.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first synchronization signal for synchronizing with a cell, the first synchronization signal transmitted at a first periodicity by a base station serving the cell. The UE may then receive, subsequent to the synchronizing, a second synchronization signal for resynchronizing with the cell. In some cases, the second synchronization signal may be transmitted by the base station according to a second periodicity that is different from the first periodicity. In some cases, the second synchronization signal may include a plurality of repetitions of a first sequence that is based at least in part on a cell identifier of the cell. The UE may communicate over the cell with the base station based at least in part on the resynchronizing.

Abstract: Methods, systems, and devices for wireless communications are described. A set of reference signal resources that are configured for sounding reference signal transmissions may be shared among user equipments (UEs) that are enabled to receive multicast communications. Each of the shared set of reference signal resources may be associated with set(s) of channel state information. UEs may measure a multicast channel to determine channel state information for the multicast channel and transmit sounding reference signals over one of the shared reference signal resources that is associated with the set of channel state information determined by the UE. A base station that receives the sounding reference signal may transmit a subsequent multicast transmission for the UEs using transmission parameters that are adapted for the set(s) of channel state information associated with the occupied sounding reference signal resource.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may receive signaling indicating a set of multicast configurations for a set of multicast modes supported by the UE. Each multicast mode of the set of multicast modes may be associated with one or more radio resource control (RRC) states. The UE may determine a multicast configuration of the set of multicast configurations based on an RRC state according to which the UE is operating. The UE may receive, while operating according to the RRC state, multicast data according to the determined multicast configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a control message including a first parameter and a second parameter. The first parameter may identify a first uplink control channel resource set for a first type of UE. The second parameter may identify a second uplink control channel resource set for a second type of UE. In some cases, a UE may receive the control message before receiving configuration information identifying a uplink control channel resource configuration. In some cases, a UE may optionally select an uplink control channel resource set based at least in part on the control message and a type of the UE. Also, a UE may transmit on an uplink using a communication configuration associated with the selected uplink control channel resource set. Numerous other aspects are provided.

Abstract: A method, apparatus, and computer-readable medium are provided that improves power savings and reliability of communication for DRX/eDRX modes. A base station may receive an indication from a network entity that a UE is in a DRX/eDRX mode. The base station may configure a WUS mode for the UE corresponding to the DRX mode or the eDRX mode. A UE may receive the WUS mode from the base station. When a UE is configured for relaxed RRM measurements for a first cell and moves to a second cell that supports a relaxed RRM measurement, the UE may return to a regular RRM measurement for a time period. When a UE configured for a WUS mode for a first cell moves to a second cell that supports the WUS mode, the UE may return to the DRX mode or the eDRX mode without the WUS mode for a period of time.

Abstract: In some aspects, the SIB1 message is transmitted in a subframe 0 and a subframe 5 of alternating radio frames of the non-anchor carrier. In some aspects, the SIB1 message is transmitted in a subframe 0 of alternating radio frames of the anchor carrier. In some aspects, the frequency domain location parameter is associated with a physical resource block offset relative to a center frequency, and the anchor carrier is in a first frequency range greater than the center frequency by the physical resource block offset and the non-anchor carrier is in a second frequency range less than the center frequency by the physical resource block offset, or the non-anchor carrier is in the first frequency range greater than the center frequency by the physical resource block offset and the anchor carrier is in the second frequency.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive one or more retransmissions of an initial group-common transmission. The UE may receive, in accordance with a first SPS configuration, a group-common transmission of a group-common downlink shared channel, the group-common transmission being associated with a first RNTI. The UE may transmit feedback information for the group-common transmission. The UE may then receive a downlink control information (DCI) message scheduling either a group-common retransmission of the group-common downlink shared channel or a unicast retransmission of the group-common downlink shared channel. The DCI may indicate that either the group-common retransmission is associated with the first RNTI or that the unicast retransmission is associated with a second RNTI that may be different from the first RNTI.
