Abstract: A method and apparatus of a device that determines an occurrence of the DL SPS or the UL CG to determine a periodicity of a packet generation is described. In an exemplary embodiment, the method receives a configuration for a downlink (DL) Semi-Persistent Scheduling (SPS) or an uplink (UL) Configured Grant (CG). The configuration includes an indication of non-integer periodicity of the DL SPS or the UL CG. Additionally, the method determines an occurrence of the DL SPS or the UL CG based on the received configuration for the DL SPS or the UL CG to determine a periodicity of a packet generation. Thereafter, the method transmits or receives data based on the configuration for the DL SPS or the UL CG.

Abstract: Disclosed herein are apparatuses, systems, and methods using or implementing dynamic beamforming in control channels, by transmitting downlink control channels to user equipment (UEs) in a number of orthogonal frequency division multiplexing (OFDM) symbols of a downlink subframe. A first OFDM symbol of the number of OFDM symbols can be transmitted using first beamforming parameters in a first direction, and a second OFDM symbol of the number of OFDM symbols can be transmitted using second beamforming parameters different from the first beamforming parameters and in a second direction different from the first direction. The number of OFDM symbols used, as well as other parameters, can be dynamically adjusted in subsequent subframes. Other embodiments are described.

Abstract: A base station (BS) and a user equipment (UE) establish a wireless link. The BS transmits first downlink control information (DCI) to the UE over an unlicensed spectrum during a first channel occupancy time (COT). The first DCI schedules a plurality of shared channel communications, which may be physical uplink shared channel (PUSCH) communications or physical downlink shared channel communication (PDSCH) communications. The first DCI also schedules an acknowledgment message for one or more of the plurality of shared channel communications. The scheduling indicated by the first DCI may include cross-COT scheduling, where one or more communications are scheduled in a second COT or outside of a COT. The UE and the BS perform the plurality of shared channel communications according to scheduling indicated by the first DCI.

Abstract: An approach to providing an indication of the availability of tracking reference signal (TRS) and/or channel state information reference signal (CSI-RS) occasions. Channels for carrying the indication include system information block (SIB) signaling, paging physical downlink control channel (PDCCH), and paging early indications. Various approaches are described that provide the information, including a number of bitmap approaches, a hierarchical informational approach, a dynamic signal indication that carries configuration indices. Additional approaches are described that reduce unnecessary overhead by specifying certain reference signal (RS) occasions as being available.

Abstract: This disclosure relates to techniques for receiving physical downlink control channel transmissions with improved reliability in a wireless communication system. A wireless device may establish a wireless link with a cellular base station. The wireless device may receive downlink control channel configuration information from the cellular base station. The downlink control channel configuration information may configure control resources associated with multiple transmission reception points in a search space for the wireless device. The wireless device may perform downlink control channel candidate blind decoding during a monitoring occasion configured by the search space configured with control resources associated with multiple transmission reception points.

Abstract: A cellular base station (BS) which transmits more flexible downlink control information (DCI) to the UE, and a UE capable of receiving and processing a received DCI message. The DCI message may have a DCI format of 0_1 or 0_2 and further may comprise an UL-SCH set to 0, a CSI request field of all 0s and an SRS request field having a nonzero value. The DCI message may indicate to the UE that the UE should: 1) transmit an aperiodic SRS corresponding to SRS request; and 2) that the UE should not transmit on the PUSCH. The DCI may include existing fields that specify either a slot offset or beam information useable when transmitting the aperiodic SRS. The base station may also generate a DCI message with an SRS trigger that is targeted to a plurality of UEs in a group, or a plurality of groups of UEs, for greater efficiency.

Abstract: This disclosure relates to techniques for a user equipment device (UE) performing a quasi-colocation (QCL) update in a wireless communication system. The UE may receive an indication to change a spatial relationship for transmission/reception. The UE may receive aperiodic reference signals for use in beam tracking according to the new spatial relationship. The UE may also receive provide aperiodic reference signals for time, frequency, and/or phase tracking. Thus, the UE may change to the new spatial relationship and use the aperiodic reference signals to quickly complete initial tracking operations.
