Abstract: Aspects described herein relate to determining and/or scheduling resources for devices in view of cross-channel interference measured between the devices. In an aspect, a first user equipment (UE) can determine a signal measurement of a signal transmitted by a second UE in a first channel, determine, based at least in part on the signal measurement, a cross-channel interference parameter of interference experienced by the first UE, and transmit, to a serving base station that serves the first UE, an indication of the cross-channel interference parameter. In another aspect, a base station can determine a cross-channel interference parameter of interference experienced by a first UE in at least a first channel, based on a signal transmitted by a second UE in a second channel, and can schedule communications for the first UE based at least in part on the cross-channel interference parameter.

The apparatus receives, from a base station, an AN configuration for one or more ANs associated with the base station. The apparatus transmits, to the base station, an AR to request assistance with communication with a second UE from at least one AN associated with the base station. The apparatus receives, from the base station, a grant to schedule sidelink transmission with the second UE. The sidelink transmission with the second UE is assisted by at least one AN of the one or more ANs associated with the base station.

For instance, a first user equipment (UE) may identify a configuration for an assisting node (AN) that includes an indication of a set of time resources during which the AN is active and an indication of location information that indicates communication direction information corresponding to communications via the AN during the set of time resources. The first UE may select a time resource from the set of time resources based on the indication of location information, a location of the first UE, and information associated with a packet for transmission from the first UE to a second UE via the assisting node. The first UE may transmit the packet over the selected time resource.

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 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.

Abstract: A first UE and a second UE may exchange information relating to one or more machine learning data services. The one or more machine learning data services may be provided by the second UE. The first UE and the second UE may pair with each other for the one or more machine learning data services. The second UE may perform machine learning inference using at least one machine learning inference model, and may transmit the inference result (e.g., a link quality prediction) associated with a link between a network node and the first UE to the network node. The network node may switch (the direction of) the network node beam if the inference result predicts that the degree of link quality degradation associated with a current network node beam is going to be greater than a prespecified threshold.

Abstract: A random access procedure between a user equipment (UE) and a base station may include repetition of a random access message 3 based on an indication provided by a random access response (RAR) message including a physical downlink control channel (PDCCH) portion and a physical downlink shared channel (PDSCH) portion. The base station may transmit the RAR message to indicate at least one random access message 3 repetition parameter. The UE may determine at least one random access message 3 repetition parameter based on the RAR message. The UE may transmit the random access message 3 with repetition based on the message 3 repetition parameter, and the base station may receive the random access message 3 based on the repetition parameter, thereby improving coverage of the random access message 3.

Abstract: Disclosed is a battery, including: a housing having a cavity; a battery cell arranged in the cavity, the battery cell includes a positive electrode plate, a negative electrode plate, and a separator; and an electrolyte solution filled in the battery cell including fluoroethylene carbonate. A width of the separator is greater than that of the positive and the negative electrode plate. The battery satisfies following relationship: C?B/20A+1, where a content of fluoroethylene carbonate in the electrolyte solution is C %, A represents a distance between an edge of the separator and that of an electrode plate on the same side, and B represents a height of the cavity. When the foregoing relationship is satisfied, deterioration of performance of the battery cell caused by insufficient electrolyte solution may be alleviated, thereby improving a value of a self-discharge coefficient k and cycling performance of the battery.

Abstract: Methods, systems, and devices for wireless communications are described. Repetitions of a reference signal may be transmitted by a first device. In some examples, the repetitions may be quasi-colocated with one another, share an antenna port, or both. The repetitions of the reference signal may arrive at a reconfigurable surface. The reconfigurable surface may apply a modulation sequence to the repetitions of the reference signal and output modulated repetitions of the reference signal in a direction based on a reflective state of the reconfigurable surface. A signal including the modulated repetitions of the reference signal may be received by a second device and combined with the modulation sequence used by the reconfigurable surface to obtain a combined signal. The combined signal may be used to determine, for the reconfigurable surface, information about a channel between the first device and the second device.

If the UE is not capable of transmitting the first and second sidelink transmissions concurrently, the UE may transmit the sidelink transmission associated with the higher priority. The first and second sidelink transmissions may be scheduled with overlapping frequency resources.
