Abstract: An apparatus, e.g., a UE, for resolution of conflicts between HD and FD configurations is disclosed. The UE receives a configuration indicating that a first set of symbols is configured for HD communication with at least one of D symbols, U symbols, or F symbols in which the F symbols are configured as D or U. The UE receives DCI scheduling FD communication including an FD transmission and an FD reception on a second set of symbols. The second set of symbols have a third set of symbols in common with the first set of symbols. The third set of symbols have conflicting HD and FD configurations. The UE cancels, based on the conflicting HD and FD configurations of the third set of symbols, at least one of the FD transmission or the FD reception in the third set of symbols.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a receiver user equipment (UE) receives, from a transmitter UE, a sidelink reference signal over a sidelink established with the transmitter UE, and transmits a sidelink timing adjust (TA) command to the transmitter UE based on the sidelink reference signal, the sidelink TA command requesting the transmitter UE to adjust a sidelink transmit time of the transmitter UE. In an aspect, a transmitter UE transmits, to a receiver UE, a sidelink reference signal over a sidelink established with the receiver UE, and receives a first sidelink TA command from the receiver UE based on the sidelink reference signal, the sidelink TA command requesting the transmitter UE to adjust a sidelink transmit time of the transmitter UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may identify a failure associated with a machine learning prediction for one or more network parameters; report, to a base station, failure information regarding the failure associated with the machine learning prediction; receive, from the base station, response information identifying an alteration to a communication configuration as a response to the failure associated with the machine learning prediction; and implement the alteration to the communication configuration based at least in part on receiving the response information. Numerus other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communication by a first, transmitting, user equipment (UE) for sidelink communication with a second, receiving, UE. The techniques generally includes determining whether to transmit sidelink control information (SCI) for decoding a physical sidelink shared channel (PSSCH) transmission to a receiving UE in one or multiple stages, transmitting the SCI in accordance with the determination, and transmitting the PSSCH in accordance with the SCI. Release 16 NR sidelink transmissions often include two (or more) stages of SCIs. The present disclosure provides methods and techniques for alternative mechanisms to achieve similar goals as the multiple stages of SCIs when the second (and the subsequent) SCI stage(s) is absent.

Abstract: An apparatus for wireless communications has a first component and a second component. The first component is within an application layer and configured to control machine learning modules in different nodes. The second component is within the application layer and configured to control data flow between the different nodes. A method of wireless communications, by a first node, comprises collecting measurements related to wireless communications and transmitting the measurements to a second node for machine learning processing. The method also includes transmitting the measurements to a third node for neural network training. A method by a user equipment (UE) includes reporting a UE capability to a server, and configuring neural network parameters in response to server feedback. The method further includes executing a neural network with the configured neural network parameters to determine a wireless communications analysis, and reporting the analysis to the server.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless device may receive, for communications with one or more of a base station or another wireless device, information identifying that an uplink transmission on a sidelink and a downlink transmission on a sidelink are to precede an uplink transmission on an access link and a downlink transmission on an access link. The wireless device may communicate, with the one or more of the base station or the other wireless device, based at least in part on the information identifying that the uplink transmission on the sidelink and the downlink transmission on the sidelink are to precede the uplink transmission on the access link and the downlink transmission on the access link. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a plurality of communications from a corresponding plurality of transmission/reception points (TRPs) included in a coordinated multipoint network. At least two communications, of the plurality of communications, may have different redundancy versions from a common codebook, and may be received in a same transmission time interval (TTI). The UE may decode the plurality of communications using joint decoding. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for forward/retransmitting a data transmission to a target UE through a helper UE. A helper UE may receive a data transmission from a network node, determining whether the received data transmission is intended for a target UE or for the helper UE itself, based on a control message, and retransmitting the data transmission to the target UE upon determining that the data transmission is intended for the target UE. A network node such as a base station may transmit a control message to at least a help UE, the control message comprising an indicator of whether a data transmission is intended for the helper UE or a target UE and transmit the data transmission to at least the helper UE and the target UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first transmit receive point (TRP) may transmit a first physical downlink shared channel (PDSCH) communication to a user equipment (UE), wherein the first PDSCH communication includes a first set of layers for a codeword, and wherein a second set of layers for the codeword are transmitted to the UE in a second PDSCH communication from a second TRP. The first TRP may receive from the UE, acknowledgement or negative acknowledgement (ACK/NACK) information corresponding to the codeword. The first TRP may adjust a contention window size based at least in part on a determination that a condition, associated with the ACK/NACK information, is satisfied.
