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 communications are described. In some examples, a wireless communications system may support short reference signals for sidelink communication. A transmitting user equipment (UE) and a receiving UE may receive, from a base station, configuration signaling that indicates a set of sidelink resources that includes a set of slots within a subcarrier. A subset of the slots may include a first set of symbols allocated to a physical sidelink shared channel (PSSCH) and a second set of symbols allocated to a reference signal, where the first set of symbols comes before the second set of symbols in a time domain. The transmitting UE may transmit, to the receiving UE, a reference signal over the second set of symbols and the receiving UE may utilize the reference signal to decode data message received from the transmitting UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may generate information indicating a reference signal and a measurement report for a first sidelink between the first UE and a second UE. The first UE may use the information for a second sidelink between the first UE and the second UE. Numerous other aspects are described.

Abstract: Aspects relate to configuration of phase-tracking reference signals (PT-RSs) in sidelink networks. A sidelink PT-RS configuration for a transmitting wireless communication device may be configured based on a sidelink channel state information (CSI) report received from a receiving wireless communication device. The transmitting wireless communication device may further transmit the sidelink PT-RS configuration to the receiving wireless communication device.

Abstract: Methods, systems, and devices for wireless communications are described. A target user equipment (UE) may communicate (e.g., transmit, receive) a message indicating a relay UE for relaying wireless communications between the target UE and a base station. The relay UE is selected from a set of candidate relay UEs based on existing sidelink relay communication links at the relay UE, candidate target UEs associated with the relay UE, existing communication sidelinks between the target UE and the candidate relay UEs, or any combination thereof. The target UE may receive a first control signal indicating a sidelink relay communication link for communicating messages between the first UE and the base station via the relay UE, and receive a second control signal activating the sidelink relay communication link. The target UE may then communicate a message to or from the base station via the relay UE and the sidelink relay communication link.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communications by a user equipment (UE) includes transmitting, in a first symbol in time of a slot, an automatic gain control (AGC) signal, wherein the UE transmits the AGC signal at a first power over a first frequency bandwidth; and transmitting, in a plurality of symbols of a mini-slot of the slot, a second AGC signal and data, wherein the UE refrains from transmitting between the first symbol and the plurality of symbols.

Abstract: Methods, systems, and devices for wireless communication are described. A first user equipment (UE) may select a sidelink beam for a second UE configured to be connected to the first UE based on a sidelink transmission configuration indicator (TCI). The sidelink TCI may include a sidelink pathloss reference signal identifier, or a sidelink power control identifier, or both. The first UE may transmit a sidelink pathloss reference signal to the second UE configured to be connected to the first UE. The sidelink pathloss reference signal may be associated with the sidelink pathloss reference signal identifier of the sidelink TCI.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive an indication of a physical uplink control channel (PUCCH) resource for providing hybrid automatic repeat request (HARQ) feedback for a sidelink data transmission from a second UE. The first UE may transmit the HARQ feedback for the sidelink data transmission on the PUCCH resource. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A receiving user equipment (UE) may broadcast messages containing inter-UE cooperation (IUC) information using multiple beams. The IUC information transmitted on each beam may be different for each beam of the receiving UE. For example, each IUC information may contain different preferred resources or non-preferred resources for the receiving UE to receive a transmission from a transmitting UE. The transmitting UE may receive a message containing IUC information from one of the beams of the receiving UE and transmit a signal using resources based on the IUC information contained in the received message. In some examples, the transmitting UE may transmit a channel busy ratio (CBR) request to a receiving UE. The CBR request may specify a transmission configuration indicator (TCI) state, spatial relation, spatial domain filter, or beam according to which the receiving UE is to measure the CBR.

Abstract: Methods, systems, and devices for identification reinterpretation in sidelink control information (SCI) are described. A first user equipment (UE) may transmit to a second UE or device, on a sidelink channel, SCI. The SCI may include a partial source and destination identifier fields and may indicate to the second UE to apply a first interpretation of multiple different interpretations for the partial source identifier field and the partial destination identifier field. For example, the SCI may indicate to interpret the partial source identifier field and the partial destination identifier field in combination as a source identifier field, as a destination identifier field, or as a partial source identifier and a partial destination identifier. The UE may transmit a medium access control (MAC) packet including a MAC header with identifier fields set to be complementary to the SCI.
