Abstract: A first wireless device, such as a user equipment, generates a message indicating a processing time for at least one of training a neural network for channel state information (CSI) derivation or for reporting the CSI based on a trained neural network. The first wireless device transmits the message indicating the processing time to a second wireless device. The second wireless device may be a network entity, such as a base station, a transmission reception point, or another UE.

Abstract: User equipments (UEs) with reduced capabilities may need a relaxed processing timeline relative to standard UEs. The relaxed processing timeline may provide UEs with reduced capabilities an appropriate amount of time (e.g., during a random access procedure) to decode messages from a base station (BS) and/or to prepare uplink messages. Aspects of the disclosure relate to a UE configured to transmit a message to a serving BS, the message including a request for timeline relaxation for transmission of a subsequent message, the message and the subsequent message being associated with a random access procedure. The UE may receive a response message associated with the random access procedure and indicating one or more timing offsets corresponding to the timeline relaxation. The UE may transmit the subsequent message to the serving BS based on the one or more timing offsets indicated by the serving BS. The subsequent message acknowledges the response message.

In one aspect, a method of wireless communication performed by a user equipment (UE), includes receiving, from a base station (BS) via a first cell, an activation command to activate a second cell different from the first cell, and receiving, from the BS via the second cell during an activation period, a first reference signal different from a synchronization signal block (SSB). The method further includes performing a measurement of the first reference signal, and operating in the second cell based on the measurement. In some aspects, using reference signals different from SSBs may reduce the delay associated with activating the secondary cell.

A method of wireless communication by a UE includes expecting a TRS to be received when a PDSCH is received.

Abstract: A UE receives control signaling that indicates that the UE is scheduled to transmit one or more uplink control channel messages on a first component carrier that overlap in a time domain with one or more uplink shared channel messages scheduled for transmission on a second component carrier. The UE resolves a first overlap of uplink control channels having a same priority level, if present, and resolves, after resolving the first overlap, a second overlap of an uplink control channel and at least one uplink shared channel having the same priority level, if present. The UE resolves two or more channels having a different priority level after resolving the first overlap and the second overlap. The UE transmits one or more uplink transmissions including at least one of the one or more uplink control channel messages and the one or more uplink shared channel messages.

Configuration information may be provided from a base station to a user equipment (UE) for autonomous uplink transmissions, that may indicate initial resources for an initial uplink transmission slot and retransmission resources for a number of retransmissions. Time resources within the retransmission resources may be configured to provide enhanced reliability, such as by being configured in non-contiguous slots to avoid one or more other transmission channels. Time resources within slots may also be configured to prevent persistent collisions with autonomous uplink transmissions or retransmissions of two or more different UEs.

A radio access network (RAN) node (e.g., a base station) can transmit at least one report setting, each associated with a selected information type, to a wireless communication device (e.g., a UE). The selected information type may be selected from a first information type and a second information type. When a report setting is associated with the first information type, the wireless communication device can transmit the L1 measurement report including both beam measurements and beam identifiers corresponding to the beam measurements for the report setting. When the report setting is associated with the second information type, the wireless communication device can exclude the beam identifiers from the L1 measurement report including the beam measurements for the report setting.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may communicate with a base station using an operating bandwidth part (BWP) that includes a first set of frequency resources. The UE may receive a group-common downlink control information (GC-DCI) message from the base station that includes a resource format indicator (RFI) for the UE (e.g., among multiple RFIs for a set of UEs in the GC-DCI) indicating a second set of frequency resources. The UE may modify the operating BWP based on the second set of frequency resources and communicate with the base station using the modified operating BWP. In some examples, the UE may switch the operating BWP to the second set of frequency resources or may reduce the operating BWP to a set of overlapping frequency resources between the first and second sets of frequency resources.

Abstract: Methods, systems, and devices for wireless communications are described. For example, a first wireless node (e.g., an integrated access and backhaul (IAB) node) may receive, from a parent base station, system information that is indicative of two random access procedure configurations. The first random access procedure configuration may be for a two-step random access procedure and the second random access procedure configuration may be different from the first random access procedure configuration (for example, an IAB-specific, a user equipment (UE)-specific, or a four-step random access procedure). The first wireless node may determine to use the first random access procedure configuration (e.g., for establishing a wireless backhaul connection with the parent base station) and may perform the two-step random access procedure with the parent base station accordingly.
