Abstract: An example method for wireless communication includes: transmitting by a base station, to a user device in a reduced power state, resource information for receiving a channel state information reference signal (CSI-RS) and tracking reference signal (TRS); transmitting the CSI-RS and TRS based on the transmitted resource information to the user device, wherein the user device has exited the reduced power state; determining whether there is paging information to transmit in a first physical downlink shared channel (PDSCH) transmission for the user device; transmitting a downlink control information message, wherein the downlink control information message is based on the determination that there is paging information for the user device, and wherein the user device has synchronized with the base station; and transmitting the first PDSCH transmission, based on the determination that there is paging information for the user device.

Abstract: An example technique for security key derivation in a wireless system includes: receiving a radio resource control (RRC) suspend message from a first node, the RRC suspend message including a first next hop (NH) chaining counter (NCC) value, entering a RRC inactive state, deriving a first node key based on the first NCC value, generating a first uplink message for transmission in the RRC inactive state based on the first node key, and transmitting the first uplink message to a node while in the RRC inactive state.

Abstract: In an example method, a user equipment (UE) device receives a plurality of Synchronization Signal Block (SSB) beams transmitted by base stations (BSes) during discovery burst transmission windows (DBTWs). For each of the SSB beams, the UE device determines an index value of the SSB beam (lSSB) within a respective one of the DBTWs, and determines a value Z=lSSB mod NSSDQCL, where NSSBQCL represents a maximum allowable number of SSB beams transmitted by each of the BSes during a single DBTW. The UE device determines whether two or more of the SSB beams are quasi co-located based on the values Z for the SSB beams, and processes wireless signals received from the BSes based on the determination.

Abstract: Systems and methods using control signaling for uplink frequency selective precoding at a user equipment (UE) are disclosed herein. A base station may indicate a transmission rank indicator (TRI), a wideband transmission precoder matrix indicator (TPMI), and one or more subband TPMI(s) to the UE. The base station may indicate, to the UE, whether to use the wideband TPMI or a subband TPMI to precode a physical uplink shared channel (PUSCH) transmission from the UE to the base station. The UE then precodes (and transmits) the PUSCH accordingly. Methods of UE application of the indicated subband TPMI(s) to subbands of the bandwidth in which a PUSCH may be transmitted are described. Methods accounting for a UE capability as to non-coherent, partial-coherent, and/or coherent precoding are described. Methods of assigning TPMI(s) to subbands in view of multiple transmission reception point (TRP) use by the UE for UE transmission are described.

Abstract: A method and apparatus for configuring default beams by a base station are disclosed and include determining configuration information that specifies a default Physical Uplink Control Channel/Sounding Reference Signal (PUCCH/SRS) beam and pathloss Reference Signal (RS) for a User Equipment (UE), and transmitting to the UE the configuration information identifying a default configuration for the default PUCCH/SRS beam and pathloss reference signal (RS). The default PUCCH/SRS beam and pathloss RS configured by the UE are based on the configuration information and a monitored Control Resource Set (CORESET) with a lowest CORESET identifier (ID) selected among a set of CORESETs in a same Bandwidth Part (BWP). The monitored CORESET selected may include two transmission configuration indicator (TCI) states. The default PUCCH/SRS beam and pathloss RS configured is based on a TCI first among the two TCI states or a TCI state with a lowest ID among the two TCI states.

Abstract: Various techniques are presented to improve phase tracking reference signal (PTRS) performance with respect to very high frequency communications. According to some embodiments, increased power boosting may be applied to improve PTRS performance, while still keeping power spectral density (PSD) within ETSI Broadband Radio Access Networks (BRAN) limits. In some cases, the power boosting may be semi-static and/or dynamic. In other embodiments, the improved performance may be achieved by dynamically changing time and/or frequency density of the PTRS. In other embodiments, a multi-port configuration may be used for the downlink PTRS. In other embodiments, one or more PTRS configurations may be determined per SCS and/or frequency band, e.g., based on traffic type, channel priority, parameters signaled in the slot format indication (SFI), etc. In other embodiments, common phase error (CPE) estimates may be obtained for those OFDM symbols without PTRS by interpolating the available PTRS estimates in the time domain.

Abstract: Systems, methods, and apparatuses for cross division duplex (XDD) operation in a wireless communication system are described herein. A user equipment (UE) is configured with one or more sub-bands (SBs) within a larger overall bandwidth (BW) (e.g., represented by a component carrier (CC), a bandwidth part (BWP), etc.), and that use uplink (UL)/downlink (DL) resource allocation(s) that may be different than the larger BW. Configurations for such SB-specific (SBS) arrangements that use guard bands (GBs) between SBs are discussed. Mechanisms for slot format indications (SFIs) within such SBs using either SBS DCI or cross-SB DCI are discussed. Mechanisms for providing SBS uplink resource for initial access (e.g., random access) using at least one initial UL BWP that is configured relative to one or more SBs and that may be used by XDD-capable UEs are discussed.

Abstract: Some aspects of this disclosure include apparatuses and methods for implementing mechanisms for downlink control information between an electronic device (for example, a UE) and a network for cell detection and measurement. For example, some aspects relate to an electronic device including a transceiver and a processor communicatively coupled to the transceiver. The processor monitors one or more paging occasions within a discontinuous repetition cycle (DRX) and can make a determination of one or more paging occasions within the DRX to not monitor. Each paging occasion may include a transmission by the network of downlink control information for one or more paging messages.
