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: 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: Improved configured grants (CGs) may include the designation of a footprint corresponding to uplink transmission of a UE, with the footprint at least partially defined by the occupied transmission time, occupied transmission frequency, and transmission power. The footprint may be adjustable and/or selectable by the UE according to the current traffic needs of the UE and within limits set for the footprint via prior signaling from the base station to the UE. The actual footprint parameters/values for the UE's uplink data transmissions may be received by the base station as part of CG uplink control information (CG-UCI) received from the UE. The base station may receive the CG-UCI over resources configured according to additional parameter values transmitted to the UE via the prior signaling from the base station. The base station may further receive uplink data on resources configured according to the actual footprint values.

Abstract: Embodiments are presented herein of apparatuses, systems, baseband processors, and methods for performing uplink communications and vehicle-to-everything sidelink communication. A wireless device receives first control information through a sidelink control channel specifying one or more first time slots for the wireless device to transmit a sidelink acknowledgment message over a sidelink feedback channel. The wireless device receives a resource grant through a downlink control channel, wherein the resource grant specifies one or more second time slots for the wireless device to transmit an uplink transmission over an uplink channel. The first and second time slots at least partially overlap, and it is selectively determined whether to transmit the sidelink acknowledgment message or the uplink transmission during the overlapping time slots.

The footprint may be adjustable and/or selectable by the UE according to the current traffic needs of the UE and within limits set for the footprint via prior signaling from the base station to the UE. The UE may indicate the actual footprint parameters/values for the UE's uplink data transmissions by transmitting CG uplink control information (CG-UCI) inclusive of the actual footprint values to the base station. The UE may transmit the CG-UCI over resources configured according to additional parameter values received via the prior signaling from the base station. The UE may further transmit uplink data on resources configured according to the actual footprint values.

Abstract: Control signaling is introduced for enhanced physical control channel (e.g. PDCCH) transmission/reception. A physical control channel may be transmitted and received using multiple beam pairs. The location of the physical control channel may be based on the search space (SS) and its associated control channel resource set (CORESET), with a specified number of transmission configuration indication (TCI) states configured for a CORESET, and/or one SS mapped to a specified number of CORESETs. The TCI states may be selected from a TCI list configured in the corresponding CORESET via radio resource control, and/or may be activated by a media access control (MAC) control element (CE). A base station (e.g. gNB) may configure more than one CORESET-ID for each SS via RRC signaling, applying the configuration for a device specific SS, or both a device specific SS and cell specific SS.

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.
