Abstract: Aspects relate to techniques for activating transmission configuration indicator (TCI) states based on a TCI state update list including a plurality of component carriers. A TCI state activation message for a physical downlink control channel (PDCCH) can include two TCI states for single frequency network (SFN) operation of a control resource set (CORESET) associated with a serving cell ID. A user equipment (UE) may receive the TCI state activation message and activate at least one of the two TCI states for each component carrier in the TCI state update list in response to the TCI state update list including the serving cell ID and based on a respective SFN configuration of each of the component carriers.

Abstract: A user equipment (UE) and a base station (BS) may transmit reference signals (RS) for the other device to estimate a channel and perform measurements. This disclosure provides for a UE to request a reference signal such as a channel state information (CSI) or a sounding reference signal (SRS). The BS transmits a radio resource control (RRC) message that configures the UE with one or more trigger states for CSI, SRS, or a combination thereof and a media access control (MAC) control element (CE) that activates a subset of the configured trigger states. In one aspect, the UE transmits an uplink request that indicates a trigger state for the UE. corresponding to at least one configured RS. The UE and the BS communicate the at least one RS corresponding to the trigger state for example, based on a grant from the BS or a time offset from the uplink request.

Abstract: Wireless communication systems and methods related to random access in a wireless communication network are provided. A user equipment (UE) receives a configuration indicating a random access preamble for a random access associated with multiple random access occasions (ROs). The UE transmits the random access preamble in one or more of the multiple ROs. The UE determines one or more random access-radio network temporary identifiers (RA-RNTIs) for the multiple ROs. The UE monitors for a random access response (RAR) message based on the one or more determined RA-RNTIs in a RAR window associated with the multiple ROs.

Abstract: Certain aspects of the present disclosure provide techniques for interference mitigation negotiation between network entities. An example method performed by a first network entity includes receiving, via different receive beams of the first network entity, a plurality of reference signals (RSs) from a second network entity associated with different transmit beams of the second network entity, transmitting, based on the plurality of RSs, downlink (DL) transmission recommendation information to the second network entity for a transmission window, and taking one or more actions related to receiving one or more uplink (UL) transmissions via one or more receive beams during the transmission window based, at least in part, on the DL transmission recommendation information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may identify multiple physical uplink control channel (PUCCH) resources in a single slot that are to be used for multiple repetitions of an uplink communication; and transmit one or more of the multiple repetitions of the uplink communication using one or more of the multiple PUCCH resources, or one or more other resources, in the same slot based at least in part on identifying the multiple PUCCH resources. Numerous other aspects are provided.

Abstract: Methods, apparatuses, and computer readable medium for PRACH repetition and Msg 3 repetition are provided. An example method may include receiving, from a base station, an indication associated with a set of PRACH resources. The example method may further include transmitting, to the base station, one or more PRACH repetitions using the set of PRACH resources. The example method may further include receiving, from the base station based on the one or more PRACH repetitions, a grant associated with a PUSCH repetition.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless communication device may identify a plurality of cells associated with serving a user equipment (UE), where each cell of the plurality of cells has been either selected for serving the UE or deselected for serving the UE. The first wireless communication device may transmit an indication of the plurality of cells associated with serving the UE to a second wireless communication device, where the indication includes information indicating whether each cell of the plurality of cells has been selected for serving the UE or has been deselected for serving the UE. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may fail to successfully receive (e.g., fail to receive, or decode) a downlink transmission. In order to suggest a solution for the reception issue to a base station, the UE may detect a reason for the failed reception. The UE may transmit, to the base station, an indication that the UE failed to decode the transmission and may receive, in response, a grant for transmission of a channel state information (CSI) report including resources allocated for an indication of the error reason. The UE may use these resources to indicate the error reason to the base station, and the base station may perform a radio link adaptation action to mitigate the error based on the error reason. In some examples, the UE may suggest the radio link adaptation action to the base station.

Abstract: Certain aspects of the present disclosure provide techniques for subchannel-based listen before talk (LBT). An example method that may be performed by a user equipment (UE) includes receiving one or more transmissions indicating one or more allocated subchannels of a frequency band that are allocated during a first time period, the frequency band comprising the one or more allocated subchannels and one or more unallocated subchannels during the first time period; sensing the one or more unallocated subchannels for at least a portion of the first time period prior to a second time period; and transmitting a signal within the frequency band during the second time period based on energy sensed for the one or more unallocated subchannels being less than a threshold.
