Abstract: Certain aspects of the present disclosure provide techniques for paging based on a paging early indication (PEI). Particular aspects provide for a method for wireless communication performed by a user equipment (UE). The method generally includes determining a set of paging cycles for receiving paging information from a base station (BS), receiving a first paging early indicator (PEI) from the BS in a first paging cycle of the set of paging cycles, wherein the first PEI indicates whether the paging information will be transmitted to the UE in one or more second paging cycles of the set of paging cycles occurring after the first paging cycle, and receiving the paging information in the one or more second paging cycles based on the first PEI received in the first paging cycle.

Abstract: Satellites in a non-terrestrial network may provide positioning reference signals (PRS) to user equipment (UE), with which the UE may determine its position using propagation delay difference measurements, such as Time Difference of Arrival (TDOA) measurement. Due to the large distances between satellites and the UE, the propagation delay differences in the PRS received from satellites may exceed half a radio frame, resulting in a frame level timing ambiguity in the differential measurements. The satellites transmit secondary PRS, along with primary PRS, that include timing information to resolve frame level timing ambiguity of the primary PRS. The positioning occasions in the secondary PRS, for example, may be aligned with corresponding positioning occasions primary PRS within each radio frame, and are transmitted with a periodicity that is an integer multiple (greater than 1) of that of the primary PRS to resolve the frame level timing ambiguity of the primary PRS.

Abstract: Certain aspects of the present disclosure provide techniques for low complexity physical downlink channel. A method that may be performed by a user equipment (UE) includes determining one or more policies for monitoring one or more physical downlink control channels (PDCCHs) within one or more bandwidth parts (BWPs) for a first type of UE, wherein the one or more policies for the first type of UE are different from a set of policies for a second type of UE; and monitoring for signals from a network entity via the one or more PDCCHs according to the determined policies.

Abstract: Some aspects of the present disclosure disclose methods and systems related to the use of a periodic reference signal to activate a secondary cell. For example, a user equipment may receive, from a base station on a primary cell, an activation command configured to activate a secondary cell. The user equipment may also receive, from the base station and on the primary cell, a signal indicating an availability of a periodic reference signal on the secondary cell, the periodic RS being for use in activating the secondary cell. The user equipment may then, in response to receiving the signal, perform a tracking function to activate the secondary cell.

Abstract: Certain aspects of the present disclosure provide techniques for high speed beam management. A method that may be performed by a user equipment (UE) includes receiving beamformed signals from at least one base station (BS); determining that the UE is in a high mobility state and one or more parameters associated with the high mobility state, based on the received signals; transmitting at least one of the one or more parameters to the at least one BS; and communicating with the at least one BS based on the one or more parameters.

Abstract: Certain aspects of the present disclosure provide techniques that may for configuration of parameters for monitoring for a combination downlink control information (DCI) that schedules data and/or reference signal transmissions in multiple cells. An example method generally includes determining, a blind decode (BD) limit and a control channel element (CCE) limit based on a scaling factor less than one, determining physical downlink control channel (PDCCH) parameters based on the BD limit and the CCE limit for monitoring for a combination downlink control information (DCI) that schedules at least one of data or reference signal (RS) transmissions in multiple cells, and monitoring for the combination DCI based on the determined PDCCH parameters.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a paging early indication (PEI) indicating whether at least one UE in a UE group or a UE sub-group including the UE is to be paged in a paging occasion. In some aspects, a sequence on which the PEI is based is a physical downlink control channel (PDCCH)-based sequence. In some aspects, the PEI is a sequence-based PEI and is received based at least in part on a sequence configuration configured on the UE. In some aspects, the PEI is a sequence-based PEI and is received based at least in part on a distributed resource block allocation associated with the sequence. The UE may selectively process a paging PDCCH associated with the paging occasion based at least in part on the PEI. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a victim user equipment (UE) may measure a cross-link interference strength from an aggressor UE based at least in part on an uplink transmission from the aggressor UE colliding with a downlink transmission to the victim UE. The victim UE may transmit cross-link interference information to the aggressor UE on a sidelink channel. For example, the cross-link interference information transmitted to the aggressor UE may indicate at least the cross-link interference strength measured by the victim UE. 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 determine a measurement of a wireless signal from a first base station of a network, the measurement comprising one or more of: a Doppler shift of the wireless signal or an angular variation of the wireless signal; determine that a high speed train or tunneling (HSTT) event has occurred based at least in part on the measurement; provide, to the first base station, an indication that the HSTT event has occurred; and receive, from the first base station, configuration information to: configure the UE for a handover to a second base station of the network, configure the UE for beam switching, or cause the UE to change a connection state. Numerous other aspects are provided.

Abstract: Idle discontinuous reception (I-DRX) cycles at a user equipment (UE) may be extended via leveraging of paging assistance from a second UE. For example, a low complexity UE may have a connection to a network (e.g., via a link to a base station) as well as a connection to another UE (e.g., via a device-to-device link to a regular UE). In cases where such a low complexity UE receives paging messages from the network, a UE associated with a device-to-device link of the low complexity UE may monitor paging messages on behalf of the low complexity UE. As such, the low complexity UE may extend its I-DRX cycle, as the assisting UE monitors paging information for the low complexity UE. The assisting UE may forward paging information for the low complexity UE according to paging occasions of the extended I-DRX cycle of the low complexity UE.
