Abstract: A method of wireless communication, executed by a user equipment (UE), receives, from a base station, a broadcast or multicast message including a known payload, as well as a configuration for the known payload. The method also trains an artificial neural network with the known payload. A method of wireless communication, executed by a base station, configures a known payload for multiple UEs and signals, to the UEs, an indication of which physical channel will include the known payload, as well as time/frequency resources of the known payload. The method also broadcasts or multicasts the known payload to facilitate neural network training at the UEs.

Abstract: Methods, systems, and devices for wireless communications are described. For example, a base station may receive, from a first user equipment (UE), an uplink message that includes one or more sidelink communication identifications each associated with a different UE of a set of one or more UEs and may associate each of the one or more sidelink communication identifications with a corresponding second identification also associated with each of the set of one or more UEs. The base station may transmit one or more signals for transitioning each of the set of one or more UEs associated with the set of second identifications from an inactive mode to an active mode based on associating each of the set of one or more sidelink communication identifications with the second identification of the set of second identifications. A second UE may receive, while in the inactive mode from the base station, the one or more signals that trigger the transition and may communicate with the first UE based on receiving the wake-up signal.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may determine a first sidelink pathloss based at least in part on a first sidelink reference signal from a second UE. The first UE may also determine a second sidelink pathloss based at least in part on a second sidelink reference signal received from a third UE. The first UE may transmit, during a transmission time interval, a first sidelink transmission to the second UE using a first transmit power that is based at least in part on the first sidelink pathloss and a second sidelink transmission to the third UE using a second transmit power that is based at least in part on the second sidelink pathloss. The first sidelink transmission may be transmitted at a first frequency and the second sidelink transmission may be transmitted at a second frequency.

Abstract: A receiving device may be either a UE or a base station. The receiving device may receive, from a transmitting device, communication based on a current reference signal (RS) pattern. The receiving device may determine, based on the received communication, at least one updated RS pattern for at least one resource block (RB). The at least one updated RS pattern may include at least one updated energy per resource element (EPRE) value for one or more RS tones. Further, the receiving device may transmit, to the transmitting device, a report of the at least one updated RS pattern. The report may correspond to at least one of an absolute value or a relative value of the at least one updated EPRE value for the one or more RS tones.

Abstract: Methods, systems, and devices for wireless communication at a user equipment (UE) are described. A first user equipment (UE) may transmit, to a set of UEs, an indication of a first semi-static traffic pattern between the first UE and a second UE. In some examples, the first semi-static traffic pattern may indicate a pattern for transmission or reception between the first UE and the second UE using a beam pair during a time period. The first UE may receive a response, from one or more UEs, indicating one or more semi-static traffic patterns for the time period. The first UE may then transmit, to a third UE of the one or more UEs, an indication of selection of a second semi-static traffic pattern for communication between the first UE and the third UE during the time period.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a set of frequency components to use in sidelink operation based at least in part on an inter-band carrier aggregation configuration. In some aspects, the set of frequency components includes one or more frequency components in a first frequency band and one or more frequency components in a second frequency band. The UE may communicate with another UE over a sidelink using one or more beams that are selected based at least in part on channel conditions associated with the one or more frequency components in the first frequency band and channel conditions associated with the one or more frequency components in the second frequency band. Numerous other aspects are provided.

Abstract: Various aspects relate generally to the beam management procedures in wireless communications systems. Some aspects more specifically relate to the selection of beams for communications to and from a UE and a network entity based on quantized orientation information for a user equipment (UE). In some implementations, a network entity can use the quantized orientation information and a machine learning model to predict a set of beams that may be suitable for communications to and from the UE and the network entity, which may be a subset of the beams that the network entity can generally use for communications to and from the UE and the network entity.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a request message to a base station while operating in an idle mode. The base station may generate, in response to the request message, a response message including a random access preamble index corresponding to the received request message. In some cases, the base station may determine a radio network temporary identifier (RNTI) based on the random access preamble index and scramble a cyclic redundancy check (CRC) of the response message with the RNTI. In some examples, the random access preamble index may be included in a payload of the response message. The UE may monitor a physical downlink control channel for the response message to the request message and receive the response message on the physical downlink control channel.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may determine whether to transmit a sidelink timing synchronization signal to a second UE based at least in part on a sidelink zone in which the first UE is located and a sidelink zone in which the second UE is located. The first UE may selectively transmit the sidelink timing synchronization signal to the second UE based at least in part on determining whether to transmit the sidelink timing synchronization signal to the second UE. Numerous other aspects are provided.

Abstract: Systems, apparatus, methods, and computer-readable media that enable and support backward cancellation indication for sidelink transmissions are described. In a situation where a sidelink data transmission with respect to one or more resources previously reserved for sidelink communication is ineffectual, a sidelink transmission user equipment (UE) may indicate the ineffectual data transmission in a transmission opportunity subsequent to the transmission having an ineffectual data transmission, such as by transmitting a backward cancellation indication (BCI). The BCI may provide information to a corresponding sidelink receiver UE regarding the resource with respect to the ineffectual data transmission. The sidelink receiver UE may use information provided by the BCI in determining whether to alter utilization of signals received on resources of the ineffectual data transmission. Other aspects and features are also claimed and described.
