  • Patent number: 11425750
    Abstract: Timing determination techniques for 5G radio access network cells are described. According to various such techniques, during a random access procedure in a 5G cell, user equipment (UE) may determine slot offset values applicable to various transmissions associated with the random access procedure using procedures that do not rely on UE-specific radio resource control (RRC) signaling. According to some such techniques, during system information acquisition in a 5G cell, a UE may determine applicable slot offset values for one or more system information block (SIB) transmissions using procedures that do not rely on UE-specific radio resource control (RRC) signaling. Other embodiments are described and claimed.

  • Patent number: 11411701
    Abstract: Embodiments of a User Equipment (UE), Next Generation Node-B (gNB) and methods of communication are generally described herein. A channel state information (CSI) report may include a CSI part 1 transmission and may be configurable to include a CSI part 2 transmission. The UE may determine a first number of coded modulation symbols per layer to be used for the CSI part 1 transmission on a physical uplink shared channel (PUSCH) without uplink shared channel (UL-SCH) data. The first number of coded modulation symbols per layer may be determined as: a minimum of a first term and a second term if the CSI report includes the CSI part 2 transmission; and the second term if the CSI report does not include the CSI part 2 transmission.

  • Publication number: 20220240182
    Abstract: Exemplary embodiments include methods for a user equipment (UE) to receive a wake-up signal (WUS) via downlink control information (DCI) transmitted by a network node in a radio access network (RAN). Such methods include receiving a physical downlink control channel (PDCCH) from the network node, and processing the received PDCCH to determine if it includes a DCI carrying a WUS targeted to the UE. The processing can include determining if a payload portion of the DCI is based on a first function of an identifier associated with the UE (e.g., C-RNTI) or with a group of UEs (e.g., WUG-RNTI). The processing can also include determining if a cyclic redundancy check (CRC) portion of the DCI is based on a second function of the identifier. Other embodiments include complementary methods performed by a network node, and UEs or network nodes configured to perform the exemplary methods.

  • Publication number: 20220232662
    Abstract: An indication of a first energy detection threshold for a first clear channel assessment (CCA) can be received at a mobile device from a cell operating on an unlicensed carrier. The first energy detection threshold can be different than a second energy detection threshold for a second CCA at a network entity of the cell. A determination can be made as to whether the unlicensed carrier is occupied based upon the first CCA and the received first energy detection threshold. A data packet can be communicated between the mobile device and the cell when the unlicensed carrier is not otherwise occupied.
