Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an acknowledgment feedback configuration for providing feedback for semi-persistent scheduling (SPS) downlink shared channels (e.g., SPS group-common physical downlink shared channels (PDSCHs), SPS unicast PDSCHs, etc.). For example, the acknowledgment feedback configuration may include separate resources for transmitting acknowledgment feedback for unicast downlink shared channels and for transmitting acknowledgment feedback for group-common downlink shared channels or may include common resources for transmitting acknowledgment feedback for both unicast downlink shared channels and group-common downlink shared channels. In some examples, the UE may multiplex acknowledgment feedback for a set of group-common downlink shared channels with additional acknowledgment feedback for other downlink channels.

Abstract: Methods, systems, and devices for wireless communications are described for uplink shared channel resource allocation for multi-cell scheduling. A user equipment (UE) may receive a downlink control information (DCI) message including a first set of bits and a second set of bits defining resource allocation across multiple network entities, as well as indicating that uplink shared channel messages to a first network entity and a second network entity are scheduled according to a resource allocation type. The first set of bits may indicate one or more resource block indices and the second set of bits may indicate one or more resource block set indices. The UE may transmit the uplink shared channel messages to the first network entity and the second network entity according to the first set of bits and the second set of bits.

Abstract: Methods, systems, and devices for wireless communications are described. The method includes receiving, from a base station and at the UE of a group of UEs, control signaling indicating a link between a first search space set and a second search space set used for a multicast broadcast service, where a first downlink control channel for the group of UEs is transmitted in the first search space set and a second downlink control channel is transmitted in the second search space set, monitoring the first search space set for a first instance of control information in the first downlink control channel and the second search space set for a second instance of the control information in the second downlink control channel, and decoding the first instance or the second instance of the control information, or both, based on the monitoring.

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, a multicast message or a broadcast message that uses a radio link control (RLC) format associated with an RLC acknowledged mode (RLC-AM). The UE may decode the multicast message or the broadcast message to identify information associated with an RLC unacknowledged mode (RLC-UM) based at least in part on a capability of the UE. The UE may operate in accordance with the RLC-UM based at least in part on decoding the multicast message or the broadcast message. 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 receive, from a base station, information that identifies an association between a first cell of a first radio access technology (RAT) and a second cell of a second RAT. The UE may perform a measurement for the first cell. The UE may determine that the measurement for the first cell satisfies a threshold value. The UE may perform an interference canceling operation for a reference signal of the second cell, or a de-weighting operation for one or more resource elements in which the reference signal interferes, based at least in part on the determination that the measurement for the first cell satisfies the threshold value and the association between the first cell and the second cell. Numerous other aspects are described.

Abstract: Wireless communications are described. A user equipment (UE) may receive a configuration message identifying a set of resources available for a plurality of UEs for transmission of feedback indications of multi-cast (or broadcast) transmission to the plurality of UEs, the set of resources comprising a plurality of subsets of resources, each subset of resources being associated with a corresponding channel metric for each UE of the plurality of UEs receiving the multi-cast transmission. The UE may determine that a feedback indication is to be provided in response to the multi-cast transmission. The UE may select, based at least in part on a channel metric of the UE, a first subset of the plurality of subsets of resources to use for transmitting a feedback message including the feedback indication. The UE may transmit the feedback message for the multi-cast transmission using resources within the selected first subset of resources.

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.

Abstract: A user equipment (UE) may be provisioned with multiple scheduling configurations and/or configured grants (CGs). Aspects of the present disclosure provide techniques for transmitting an indication from the UE to the base station indicating that the UE has no data to be transmitted to the BS during the allocated transmission time interval in order to prevent base station from allocating resources for transmission.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to receive, while the UE is in wireless communications with a first serving cell supported by a base station, an indication to activate or deactivate a second serving cell supported by the base station. The UE may receive a reference signal from the base station via the first serving cell, the reference signal received a duration of time after receipt of the indication, where the duration of time is an interruption period for the wireless communications with the first serving cell. The UE may then resume the wireless communications with the first serving cell based on the interruption period ending at receipt of the reference signal.

Abstract: This disclosure provides systems, methods and apparatus, and computer programs encoded on computer storage media, for managing cross-carrier scheduling. In one aspect, a processor of a wireless device may determine whether downlink control information (DCI) received from a secondary cell schedules communications on a primary cell, and may determine cross-carrier scheduling of communications on the primary cell in response to determining that the DCI received from the secondary cell schedules communications on the primary cell. In another aspect, processor of a network device may schedule communications on the primary cell in the DCI of the secondary cell, and may perform cross-carrier scheduling of communications on the primary cell based on the DCI of the secondary cell.
