Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may receive a downlink (DL) reception indication during an active duration of a discontinuous reception (DRX) configuration. The DL reception indication may indicate the presence of a reception opportunity following an inactivity interval, as well as the length of the inactivity interval. The wireless device may refrain from DL monitoring during the inactivity interval. In some cases, the wireless device may enter a sleep mode during the inactivity interval and wake up to receive a subsequent transmission during the reception opportunity. In some examples, the wireless device may use the inactivity interval to communicate using a different radio access technology (RAT).

Abstract: A user equipment (UE) may report capabilities pertaining to UE feedback processing, such as a number of simultaneous feedback reports that can be processed and reported by the UE for various types of feedback. For example, UE feedback processing capability may depend on channel state information (CSI) processing units (CPUs) available to the UE for feedback processing operations (e. g., for performing channel measurements, processing feedback, generating a feedback report, etc.). A UE may report feedback processing capability separately for periodic feedback reporting and for aperiodic feedback reporting, for different types of feedback reporting (e. g., for CSI reporting, for beam management reporting, etc.), etc. As such, a UE may more efficiently report capabilities pertaining to UE feedback processing, and a base station may more efficiently configure UE feedback reporting according to UE feedback processing capability.

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.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine a mapping between synchronization signal blocks (SSBs) and a random access message of a two-step random access procedure based on an indication in system information signaling or radio resource control (RRC) signaling. The random access message may include a random access preamble and a random access payload. The UE may determine, based on the mapping, an association between one or more beams carrying the SSBs and one or more additional beams carrying the random access preamble and the random access payload of the random access message. As a result, the UE may perform the two-step random access procedure with a base station according to the beam association, and coexist with a four-step random access procedure in a more reliable and efficient manner.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured with comprising a set of monitoring occasions for a reference signal. While the UE is in an inactive mode or an idle mode, a configuration for the set of monitoring occasions may be updated. The UE may be transmitted an indication of the updated set of monitoring occasions while the UE is in the inactive mode or the idle mode. The indication for the updated set of monitoring occasions may be sent via paging or system information messages.

In some aspects, a user equipment (UE) may receive a paging early indication that indicates one or more paging occasions (POs) in a quantity of paging frames based at least in part on a maximum quantity of paging frames. The UE may process a physical downlink control channel communication received in a PO of the one or more POs. Numerous other aspects are described.

Abstract: Techniques are described for wireless communication. One method includes identifying a traffic condition associated with data to be transmitted between a network access device and at least one user equipment (UE); selecting, based at least in part on the traffic condition, a dynamic subframe type of a time-division duplex (TDD) subframe; and indicating the dynamic subframe type in a TDD header of the TDD subframe. Another method includes identifying, in a TDD header of a subframe, an indication of a dynamic subframe type of the TDD subframe; and transmitting data or receiving data in a data region of the TDD subframe based at least in part on the dynamic subframe type.

Abstract: Methods, systems, and devices for wireless communication are described. A method may include receiving a control transmission from a base station, identifying a control channel search space organized according to a nested structure, the control channel search space including a plurality of control channel candidates associated with one or more control channel elements (CCEs) and an aggregation level, and searching the received control transmission to identify a control channel for the UE using the plurality of control channel candidates. Another method may include determining whether to reorder resource element group (REG) indices for a received control channel transmission based, at least in part, on a transmission mode associated with the control channel transmission. Another method may include decoding a received control channel transmission, where the downlink control information (DCI) formats may be constrained to an integer multiple of a predetermined base number of bits N.

Abstract: Certain aspects of the present disclosure provide techniques for coordinated power savings configurations for access link and sidelink(s). A wireless node may receive information from a user equipment (UE) over a sidelink. In some aspects, the wireless node forwards the information to a base station (BS) over an access link and receives, from the BS, a first power savings configuration for the access link and a second power savings configuration for the sidelink. In some aspects, the wireless node receives, from a BS, a first power savings configuration for an access link and determines a second power savings configuration for the sidelink based on the information and the first power savings configuration.
