    Abstract: Systems and methods for beam management in a wireless communication system are provided. In a network with a full duplex network entity communicating with two UEs, the network entity may configure cross-link interference (CLI) resources such that the interference between the devices may be characterized. One UE may transmit a reference signal which is read by the other device. Based on the measurement, a report may be sent to the network entity. The network entity may use the information in the report to then base scheduling decisions, and/or indicate to the UEs which beams are restricted from use in order to avoid excessive interference.

    Abstract: Methods, systems, and devices for wireless communication are described. A device, such as a user equipment (UE) may receive a set of synchronization signal blocks (SSBs) from multiple transmit-receive points (mTRPs). The set of SSB may include a first subset of SSBs associated with a first TRP and a second subset of SSBs associated with a second TRP. Each SSB may correspond to a respective directional beam (e.g., a transmit beam, a receive beam). The UE may transmit, to a base station, an indication of a selected first SSB from the first subset of SSBs associated with the first TRP and a selected second SSB from the second subset of SSBs associated with the second TRP. The UE may perform a random access channel procedure with the base station, the first TRP, the second TRP, or a combination thereof based on the transmitted indication.

    Abstract: Certain aspects of the present disclosure provide techniques for configuring a transmission configuration indicator (TCI) state application time for at least one common multi-channel TCI state. A method that may be performed by a user equipment (UE) includes receiving a TCI state indication from a network, wherein the TCI state indication comprises at least one common multi-channel TCI state, and configuring a TCI state application time for the at least one common multi-channel TCI state based on one or more factors.

    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) or a base station may be configured to indicate that a transmission occasion is empty while operating in a full-duplex mode. In some examples, the UE may transmit, to the base station, an indication that an uplink transmission occasion (for example, a configured grant transmission occasion) will not be used by the UE for transmitting an uplink communication. In some other examples, the base station may transmit, to the UE, an indication a downlink transmission occasion (for example, semi-persistent scheduling transmission occasion) will not be used by the base station for transmitting a downlink communication. If uplink or downlink transmission occasions are empty, the UE and the base station may each update parameters to operate in a half-duplex mode.

    Abstract: Aspects for MAC CE configurations for beam failure recovery operations are disclosed. In one aspect, a method of wireless communication comprising: determining, by a user equipment (UE), a beam failure recovery for a serving cell; transmitting, by the UE, a beam failure recovery request for the serving cell; and transmitting, by the UE, a MAC CE including new beam information and including serving cell identification information multiple serving cells, including the serving cell, wherein the serving cell identification information identifies the multiple serving cells. In another aspect, the MAC CE may include bandwidth part information. Other aspects and features are also claimed and described.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may transmit, to a second UE, a first message to indicate a sidelink bandwidth part (BWP) switch, for the first UE, to a first sidelink BWP, wherein the first message includes an indication of the first sidelink BWP and a first sidelink resource pool in the first sidelink BWP. The UE may receive, from the second UE, a second message that confirms the sidelink BWP switch for the first UE. The UE may transmit, to the second UE, a third message to activate the sidelink BWP switch, for the first UE, to the first sidelink BWP, based at least in part on receiving the second message that confirms the sidelink BWP switch. Numerous other aspects are described.

    Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to mechanisms for priority based decisions regarding when to cancel or maintain configured transmissions that overlap with dynamically scheduled transmissions. An example method performed by a user equipment (UE) generally includes determining that a configured transmission overlaps in time with a dynamically scheduled transmission, and deciding whether to cancel or maintain the configured transmission based on a priority of at least one of the configured transmission or an uplink transmission associated with the dynamically scheduled transmission when the time between an end of a downlink control information (DCI) that scheduled the dynamically scheduled transmission and a start of the configured transmission is greater than a threshold processing time.

    Abstract: An apparatus, e.g., a UE, for resolution of conflicts between HD and FD configurations is disclosed. The UE receives a configuration indicating that a first set of symbols is configured for HD communication with at least one of D symbols, U symbols, or F symbols in which the F symbols are configured as D or U. The UE receives DCI scheduling FD communication including an FD transmission and an FD reception on a second set of symbols. The second set of symbols have a third set of symbols in common with the first set of symbols. The third set of symbols have conflicting HD and FD configurations. The UE cancels, based on the conflicting HD and FD configurations of the third set of symbols, at least one of the FD transmission or the FD reception in the third set of symbols.

    Abstract: Methods, systems, and devices for wireless communications are disclosed. A user equipment (UE) may receive control signaling scheduling downlink messages and indicating one or more transmission configuration indicator (TCI) states for reception of the one or more downlink messages during multiple transmission and reception point (mTRP) operation. The UE may identify that the downlink messages are scheduled for reception prior to an end of an offset window associated with processing the one or more TCI states. The UE may select one or more default unified TCI states to receive the downlink messages based on one or more conditions or parameters. The UE may receive the one or more downlink messages via the selected one or more default unified TCI states based on an arrival of the one or more downlink messages occurring prior to the end of the offset window.
