Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may alter, or otherwise cancel, a sidelink communication as a result of a cancelation indicator (CI) corresponding to a different UE to support automatic gain control (AGC) calibration. The UE may determine to cancel or alter sidelink resources that at least partially overlap in time and are adjacent to, yet non-overlapping, in frequency to a high priority transmission. In some implementations, the UE may cancel the sidelink communication from an earliest overlapping symbol to the end of a slot. In other implementations, the UE may cancel a portion of the sidelink communication and resume sidelink communications within the same slot. Additionally or alternatively, the UE may utilize one or more reference signals or symbols to enable AGC recalibration during the slot.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) sends, to a network entity, a report indicating positioning capabilities of the UE, the positioning capabilities indicating a number of positioning calculations that the UE can perform per unit of time, per unit of frequency, or both, and performs a first set of positioning-related measurements of a set of positioning reference signal (PRS) resources and reports a second set of positioning-related measurements based on the reported positioning capabilities of the UE, the set of PRS resources to be used for the first and second sets of positioning-related measurements, a set of reporting parameters, an accuracy configuration, a latency configuration, or any combination thereof.

Abstract: Wireless communications systems and methods are provided relating to a physical uplink shared channel (PUSCH) repetition adaptation scheme when one or more PUSCH repetitions are discarded due to collisions. Specifically, a user equipment (UE) may obtain data for uplink transmission over a plurality of repeated PUSCH instances. In response to determining that at least one repeated PUSCH instance collides with one or more downlink symbol transmissions, the UE may discard the at least one repeated PUSCH instance. The UE may then retransmit data that was scheduled to be transmitted over the at least one repeated PUSCH instance over configured resource that was configured for uplink transmission with configured grants.

Abstract: A transmitter may be configured to determine a coding rate at which to encode data packets based on a quantity of encoded packets used by a receiver for recovery of one data packet. The transmitter may be further configured to transmit a set of encoded packets generated at the coding rate to the receiver. The receiver may be configured to receive, from the transmitter, encoded packets carrying a set of data packets encoded at a coding rate. The receiver may be further configured to transmit, to the transmitter, feedback indicating a quantity of a set of the encoded packets used for recovery of one data packet of the set of data packets. The receiver may be further configured to receive, from the transmitter, other encoded packets carrying another set of data packets encoded at another coding rate.

Abstract: Techniques are described herein for beam pair link procedures used in dual connectivity operations. A master base station may be configured to determine a timing window for a user equipment (UE) to monitor a downlink channel associated with a secondary base station. In some cases, the master base station may determine the timing window during a dual connectivity procedure or during a carrier aggregation procedure. The UE may monitor the downlink channel during the timing window and establish a beam pair link with the secondary base station based on the monitoring.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, on a sidelink, a groupcast communication and a unicast communication concurrently from a transmitter. The UE may determine a feedback sequence to be transmitted to indicate joint acknowledgment or negative acknowledgement feedback for the groupcast communication and the unicast communication based at least in part on a decoding of the groupcast communication. The UE may transmit the feedback sequence in one or more sidelink feedback resources associated with a sidelink subchannel via which at least one of the groupcast communication or the unicast communication is received. Numerous other aspects are provided.

Abstract: An apparatus for wireless communication based on sidelink accumulates a value, e.g., a token value, based on an accumulation rate of a transmit beam. When the apparatus has a packet for transmission over sidelink, the apparatus determines whether to transmit the packet over the sidelink based on a current accumulation of the value. The accumulation may be based on any of a CBR, a CR, and/or a feedback rate. A base station may measure interference on an access link of the base station and transmit a side link parameter that controls accumulation of a value at a transmitting device for the transmission of sidelink communication based on the measured interference.

Abstract: Methods, systems, and devices for wireless communications are described. One or more user equipments (UEs) may support reserved resource indications for sidelink systems. In some examples, a first UE may transmit a first sidelink control message to at least a second UE in a first transmission time interval (TTI), which may schedule a first set of time-frequency resources for a sidelink message. The first UE may transmit the sidelink message to the second UE using the first set of time frequency resources. After transmitting the sidelink message, the first UE may transmit a second sidelink control message to the second UE in a second TTI, which may indicate the first set of time-frequency resources used for transmission of the sidelink message. In some examples, the second UE may perform a decoding procedure for the sidelink message based on the second sidelink control message.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine its position based on one or more position reference signals (PRSs), which the UE receives via different component carriers (CCs). The UE may maintain an active state with a first CC transmitting a PRS, while activating and deactivating a secondary CC that may transmit PRSs based on a periodic interval. Additionally, the UE may apply similar techniques for inactive BWPs where a PRS spans multiple BWPs. In some implementations, the position of the UE may enhance a UE mobility procedure based on determining a resource to use for the UE mobility procedure that is dependent upon the position of the UE. For example, the UE mobility procedure may include a random access procedure or a handover procedure. Additionally, the resources used for the mobility procedures may be quasi co-located with PRSs.
