Abstract: Systems, methods, and circuitries are provided for direct transmission of uplink data by an INACTIVE UE using a contention free random access (CFRA) process. In one example, a method, includes, receiving, from a network, configuration of a dedicated physical random access channel (PRACH) resource or a dedicated preamble resource (dedicated PRACH/preamble resource); and while in a radio resource control (RRC) INACTIVE state, without entering an RRC CONNECTED state, using a contention-free random access (CFRA) process to transmit uplink data to a base station using the dedicated PRACH/preamble resource.

Abstract: An example method for wireless communication includes: receiving, by 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); exiting the reduced power state to receive the CSI-RS and TRS, based on the resource information; synchronizing with a base station, based on the received CSI-RS and TRS, to receive a downlink control information message; receiving paging information in a first physical downlink shared channel (PDSCH) transmission based on the received downlink control information message; determining whether there is paging information in the first PDSCH transmission for the user device; starting a Random Access Channel (RACH) procedure to make a Radio Resource Control (RRC) connection, based on determining that there is paging information for the user device; and returning to the reduced power state, based on determining that there is not paging information for the user device.

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: This disclosure relates to techniques for providing broadcast and multicast services to wireless devices while in idle and Inactive modes a wireless communication system. A wireless device may establish a wireless link with a cellular base station of a cellular network. The wireless device may receive information indicating whether provision of a broadcast or multicast service in one or more of an inactive mode or an idle mode is supported by the cellular network. The wireless device may receive the broadcast or multicast service in one or more of the inactive mode or the idle mode based at least in part on the information indicating whether provision of the broadcast or multicast service in one or more of the inactive mode or the idle mode is supported by the cellular network.

Abstract: This disclosure relates to techniques for efficient sparse network resource usage and connection release procedures. According to some embodiments, a wireless device may utilize techniques for efficiently releasing a radio resource control (RRC) connection, including techniques that avoid or reduce the occurrence of random access procedures when out-of-sync with the network when the RRC connection is being released. In some embodiments, a wireless device may utilize techniques for efficiently sparsely using network uplink resources, including techniques that avoid or reduce the occurrence of random access procedures to regain timing alignment to perform uplink communication when out-of-sync with the network.

Abstract: This disclosure relates to performing cellular communication using a power efficient downlink control information framework. A wireless device and a cellular base station may exchange configuration information indicating that the cellular base station and the wireless device support a sleep downlink control information (sDCI) format. An sDCI configuration according to the sDCI format may be negotiated, including selecting at least one sDCI configuration parameter based at least in part on an application type currently associated with cellular communication between the cellular base station and the wireless device. Downlink control information may be provided during one or more subframes in accordance with the sDCI configuration. One or more subframes for which no downlink control information will be provided to the wireless device may be determined based at least in part on the sDCI configuration.
