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: A method and apparatus of a device that handles time-varying packet size in the downlink. In some embodiments, the method performed by a user equipment (UE) comprises: receiving a first signaling comprising configuration of downlink (DL) Semi-Persistent Scheduling (SPS), wherein the DL SPS configuration comprises a periodicity of the DL SPS and a first indication for a first physical layer resource, and wherein the first physical layer resource is used to dynamically modify size of a second physical layer resource for SPS DL data transmission; receiving a second signaling that activates reception based on the DL SPS, wherein the second signaling comprises information to specify a boundary of the second physical layer resource; monitoring the first physical layer resource on each SPS occasion based on the periodicity to decode a second indication; determining the size of the second physical layer resource for SPS DL data transmission, based on the second indication; and receiving data on the second physical layer resource determined for each SPS occasion based on the determined size.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing techniques for providing a user equipment (UE) with on-demand reference signals for location related measurements of the UE. The UE can receive location assistance data from a network server, where the location assistance data includes information about a plurality of downlink reference signals that can be used to perform location related measurements by the UE. The UE can send a request to a base station for a reference signal. The reference signal is selected from the plurality of downlink reference signals of the location assistance data. Furthermore, the UE can receive the reference signal from the base station, and perform a location related measurement based on the received reference signal.

Abstract: This disclosure relates to techniques for signaling a quasi-colocation (QCL) update in a wireless communication system. A network or base station may indicate to a UE to change a spatial relationship for transmission/reception. The base station may provide aperiodic reference signals for the UE to use in beam tracking according to the new spatial relationship. Optionally, the base station may also provide aperiodic reference signals for time, frequency, and/or phase tracking. Thus, the network may configure the UE to change to the new spatial relationship and use the aperiodic reference signals to quickly complete initial tracking operations.
