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.

Abstract: A user equipment (UE) in a radio resource connection (RRC) inactive or idle state may initiate a random access procedure with a base station (BS) for initial access to a network, to resume an RRC connection, to re-establish an RRC connection, or to perform an early data transmission to a network. The BS may selectively include a timing advance (TA) medium access control (MAC) control element (CE) and an indication of a simplified timing advance command for the UE. The aspects herein may reduce the signaling overhead of the TA MAC CE. For example, the UE may enter an idle state or an inactive state. The UE may transmit a random access message to the BS with a request for timing advance simplification based, at least in part, on a TA value corresponding to the BS, wherein the TA value is applied to the transmission of the random access message.

Abstract: Certain aspects of the present disclosure provide techniques for coordinated sidelink power savings configurations. A wireless node may select a sidelink power savings configuration to use for a sidelink between the wireless node and a user equipment (UE), provide the selected configuration to the UE, and follow the configuration for the sidelink. The selection may be based on input from the UE or without input from the UE. The selection may be a current power savings configuration at the wireless node, a power savings configuration suggest by the UE, or a different power savings configuration determined by the wireless node based on the current and suggested power savings configuration. When a new UE connects to the wireless node, the wireless node may reselect a power savings configuration to use for the sidelinks and provide the reselected power savings configuration to the UEs having a sidelink with the wireless node.

Abstract: Certain aspects of the present disclosure provide techniques for allocating a resource budget for blinding decoding among various types of DCI. A method that may be performed by a user equipment (UE) includes allocating a resource budget per a span of symbols among a first type of downlink control information (DCI) and a second type of DCI, wherein the resource budget includes a number of physical downlink control channel (PDCCH) blind decodes (BDs) and a number of control channel elements (CCEs) supported by the UE; and monitoring, from a network entity, PDCCH candidates in accordance with the allocated resource budget.

Abstract: Certain aspects of the present disclosure provide techniques for channel state information measurement adaptation to maximum multiple-input multiple-output layers. A method that may be performed by a user equipment (UE) includes receiving a first channel state information (CSI) report configuration including one or more first CSI reference signal (CSI-RS) resources, wherein each first CSI-RS resource comprises a first resource set; determining, based on an indication of a maximum number of multiple-input multiple-output (MIMO) layers that the UE is expected to receive, a first resource subset on which to report first CSI; and reporting the first CSI to a base station (BS), wherein the first CSI is based on the determined first resource subset.

Abstract: Aspects relate to wireless communications utilizing cross carrier scheduling Methods and apparatus include generating at least one slot in a control channel from a scheduling cell, the at least one slot including a plurality of control channel segments such as PDCCH segments, which are arranged at respective times within the at least one slot. Each of the control channel segments includes control information such as DCIs corresponding to respective slots for a scheduled cell. Distributing the control channel information in segments or spans over time affords improved decoding timing in a UE in the scheduled cell.
