Abstract: A method of wireless communication receives multiple beams from a base station. The method also simultaneously reports a signal to interference plus noise ratio (SINR) for multiple beams with a single channel measurement resource (CMR) and a single interference measurement resource (IMR). The single IMR is configured for multiple interference sources. A method of wireless communication by a base station configures a UE with a group of interference sources. The base station also configures the UE with an interference measurement resource associated with the group of interference sources.

Abstract: A method, a computer-readable medium, and an apparatus are provided for wireless communication including random access between a base station and a user equipment (UE). The UE transmits a first random access message to a serving cell. The UE receives a second random access message from the serving cell, in response to the first random access message. The UE transmits a third random access message to one or more transmission reception points of the serving cell in a beam sweep pattern for reception on multiple beams and using resources based on at least one of a beam pool index or a TRP index.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information associated with monitoring link quality on a non-serving cell of the UE, wherein the configuration information includes at least one of: information indicating a reference signal resource associated with the non-serving cell, or information indicating an uplink resource associated with the non-serving cell; monitor a reference signal of the non-serving cell based at least in part on the configuration information; and transmit, to a serving cell using the uplink resource, a channel quality indicator associated with the non-serving cell based at least in part on the monitoring. Numerous other aspects are provided.

Abstract: A UE receives a configuration for one or more downlink reference signal or downlink channel from a base station and receives an indication of one or more time and frequency resources for full-duplex communication at the base station. The UE skips reception of the one or more downlink reference signal or downlink channel based at least in part on the indication of the one or more time and frequency resources for the full-duplex communication at the base station. A UE receives, from a base station, an allocation of uplink resources for an uplink transmission and receives an indication of one or more time and frequency resources for full-duplex communication at the base station. The UE transmits the uplink transmission to avoid the one or more time and frequency resources for the full-duplex communication at the base station.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a downlink control information (DCI) transmission that schedules an uplink communication and a downlink communication and that indicates a gap between reception of the DCI transmission and transmission of the uplink communication. The UE may receive the downlink communication and transmit the uplink communication based at least in part on the DCI transmission and the gap. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may identify an applicable restricted resource scheduling rule for restricting full-duplex operation on a first set of resources. The base station may transmit one or more control messages scheduling one or more full-duplex communications on a second set of resources based on the applicable restricted resource scheduling rule for restricting full-duplex operation on the first set of resources. In some examples, the second set of resources may overlap in time with the first set of resources. In other examples, the second set of resources may not overlap with the first set of resources in time or frequency. Accordingly, the base station may communicate the one or more full-duplex communications on the second set of resources. The described techniques may enable the base station to perform full-duplex communications with reduced interference and improved reliability.

Abstract: Aspects described herein relate to determining multiple beams to use in transmitting messages in a random access procedure with one or more transmission/reception points (TRPs) of a cell, and transmitting, to the one or more TRPs of the cell, multiple instances of a first random access message based on the multiple beams, where each of the multiple instances of the first random access message include a preamble portion and a payload portion. In another aspect, a node receiving the multiple instances of the first random access message can determine multiple beams to use in transmitting messages in the random access procedure and can transmit with one or multiple TRPs, to the UE and in response to the first random access message, multiple instances of a second random access message based on the multiple beams.
