Abstract: Aspects of the present disclosure provide techniques for using automatic gain control symbols to indicate a sidelink mini-slot. A method performed by a transmitting user equipment includes transmitting, during a first time portion of a symbol within a slot, a first beam associated with a first receiving user equipment. The first time portion of the symbol is configured to indicate that the first receiving user equipment will receive another transmission from the transmitting user equipment during a first mini-slot within the slot associated with the first time portion. The method may further include transmitting, during a second time portion of the symbol within the slot, a second beam associated with a second receiving user equipment. The second time portion of the symbol is configured to indicate that the second receiving user equipment will receive another transmission from the transmitting user equipment during a second mini-slot within the slot.

Abstract: Methods, systems, and devices for wireless communication are described. A first user equipment (UE) may receive, from a second UE, an indication of a first uplink timing advance for communications from the second UE to a base station. The UE may estimate, based at least in part on the first uplink timing advance received from the second UE, a second uplink timing advance for transmission of a random access message from the first UE to the base station. The UE may transmit, to the base station, the random access message using the second uplink timing advance.

Abstract: Aspects are provided which allow AGC symbols to be applied for identifying or indicating target Rx UEs of sidelink communications from Tx UEs. A Tx UE transmits an AGC signal to a Rx UE in a RB associated with the Rx UE. The Rx UE receives the AGC signal from the Tx UE. The Tx UE transmits sidelink data to the Rx UE after the AGC signal. The Rx UE decodes sidelink data from the Tx UE in response to the AGC signal being received in a RB associated with the Rx UE. The Rx UE refrains from decoding the sidelink data from the Tx UE in response to the AGC signal being received in a different RB than the RB associated with the Rx UE. In this way, Rx UEs may save monitoring and processing power and time in receiving and decoding sidelink communications.

Abstract: A first UE may receive SCI including one or more resource reservations of a second UE based on an indication from a MAC layer to a PHY layer to monitor for the SCI including the one or more resource reservations of the second UE. The indication from the MAC layer to the PHY layer may trigger at least one of a sensing beam, a TCI state, or a spatial relation. The at least one of the sensing beam, the TCI state, or the spatial relation may be associated with monitoring for the SCI including the one or more resource reservations of the second UE. The first UE may transmit a beam to a target UE on one or more resources that are selected based on the one or more resource reservations of the second UE.

Abstract: In multi-beam communication, the UE may assist in the scheduling of beams utilized during the multi-beam communication by improving the manner in which the quality of the beam is reported to the network. The apparatus may measure a signal received from a base station on at least one beam. The apparatus may detect a triggering event for providing CSI for the at least one beam. The apparatus may transmit an uplink transmission comprising a CSI report in response to detecting the triggering event. The apparatus may receive an uplink request from a UE for providing CSI for at least one beam. The apparatus may transmit an indication scheduling a CSI report in response to the uplink request. The apparatus may receive an uplink transmission from the UE comprising the CSI report for the at least one beam.

Abstract: Aspects relate to grouping sidelink carriers in a wireless communication network. A first wireless communication device, such as a user equipment (UE), may communicate with a base station on a cellular link utilizing a first set of first component carriers (CCs) in a particular frequency band. The UE may identify one or more first carrier groupings for the first set of first CCs with the base station. The UE may communicate with a second wireless communication device, such as a second UE, on a sidelink utilizing a second set of CCs within the same frequency band. The first UE may map at least one second CC to a respective corresponding first CC and apply the one more carrier groupings to the second set of CCs to generate one or more second carrier groupings based on the mapping.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first node may transmit, to a second node on a beamformed link from the first node to the second node, a first signal, wherein the first node and the second node are associated with common timing; determine whether a second signal, based at least in part on the first signal, is received on a beamformed link from the second node to the first node; and transmit a third signal based at least in part on receiving the second signal or perform a sidelink beam failure recovery procedure based at least in part on determining that the second signal is not received. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for configuring sidelink slots without symbols for automatic gain control. One aspect provides a method for wireless communication by a user equipment, including receiving a first cyclic prefix of a first symbol within a slot at the user equipment. The method further includes configuring a first automatic gain control setting based on a received power in the first cyclic prefix of the first symbol, and receiving a data portion of the first symbol using the first automatic gain control setting.

Abstract: Methods, systems, and devices for wireless communication are described. In some systems, a user equipment (UE) may transmit, to a network entity, a first signal including a request to update a resolution of a phase shifting operation associated with beam-based communications. The UE may receive, from the network entity, a second signal approving the request. The UE may communicate using a beam according to an updated resolution of the phase shifting operation based on the second signal approving the request. Additionally, or alternatively, the UE may transmit a first signal including a request to suspend a beam refinement process based on the resolution of the phase shifting operation. The UE may receive a second signal approving the request to suspend the beam refinement process. The UE may communicate with the network entity using a beam based on suspending further beam refinement in response to the second signal.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication of a first slot-related channel sensing procedure to perform during channel sensing. The first slot-related channel sensing procedure may be one of multiple available slot-related channel sensing procedures. The first slot-related channel sensing procedure may indicate time interval increments in which to perform the channel sensing. The UE may perform the first slot-related channel sensing procedure based on the indication. The UE may perform the first slot-related channel sensing procedure in the time interval increments of a sidelink resource pool to identify a first time-frequency resource of the sidelink resource pool that is available for transmission of a sidelink message.
