    Abstract: Methods, systems, and devices for wireless communications are described. In a wireless communications system, a user equipment (UE) may transmit, to a base station associated with a first subscription, first control signaling indicating a configuration for a set of tune away occasions in which the UE is to tune away from the first subscription to a second subscription to monitor for paging signaling for the second subscription. The UE may transmit second control signaling a suspension of one or multiple tune away occasions based on the configuration, the suspension indicating that the UE may refrain from tuning away from the first subscription during the tune away occasions. Based on transmitting the second control signaling, the UE may communicate data with the base station and refrain from monitoring for the paging signaling during the suspended tune away occasion.

    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: Methods, systems, and devices for wireless communication are described. A base station may transmit a grant to a first user equipment (UE) that indicates a resource allocation for a sidelink communication, either from the first UE to a second UE or from the second UE to the first UE. The grant may include a destination identifier associated with the sidelink communication, as well as a mapping between the resource allocation and the destination identifier. The destination identifier may be based on information in an indication received from the first UE. In some examples, the base station may configure a default receiver UE for transmissions from the first UE, and the base station may identify a receiver UE in the grant if the intended receiver UE is different than the default receiver UE.

    Abstract: This disclosure provides systems, methods, and devices for wireless communication that support enhanced ESL position determination and ESL position based notifications. In a first aspect, a method of wireless communication includes obtaining first position information for an asset of one or more assets associated with an electronic shelf label system based on first wireless information, and the first position information is associated with a first time. The method also includes obtaining second position information for the asset based on second wireless information, and the second position information is associated with a second time. The method further includes determining a notification for the asset based on the first position information, the second position information, the first time, and the second time. Other aspects and features are also claimed and described.

    Abstract: This disclosure provides systems, methods, and devices for Electronic Shelf Label (ESL) systems that support positioning of ESL devices. In a first aspect, a method includes: determining known positions of a first subset of ESL devices; receiving positioning measurements for each ESL device in a second subset of ESL devices; estimating a first position of each ESL device in the second subset based on the positioning measurements received for that ESL device and the known positions of the first subset; determining a positioning error associated with the first position of each ESL device in the second subset; and estimating a second position of each ESL device in the second subset based on the positioning error and additional positioning measurements received for that ESL device. Other aspects and features are also claimed and described.

    Abstract: Systems, methods, and apparatuses, including computer programs encoded on computer storage media, are directed to configuration of a beamforming vector using an estimated covariance matrix, which may reduce latency commensurate with a beam training procedure. An apparatus may receive, from another apparatus, information indicating a configured subset of a set of TX beams at the other apparatus. The other apparatus may transmit pilot signals via the configured subset of the set of TX beams. The apparatus may transmit, to the other apparatus, information associated with the set of beam pairs of the apparatus and the other apparatus. The apparatus may estimate a channel covariance matrix using the accumulated signal strength value, and may calculate a beamforming vector from the channel covariance matrix. The apparatus and the other apparatus may perform a beam training procedure using respective beamforming vectors.
