  • Patent number: 11849447
    Abstract: A generation-Node B (gNB) configured for unlicensed spectrum operation above 52.6 GHz in a fifth-generation new-radio (NR) system (5GS) may encode a parameter (e.g., ssb-PositionsInBurst) for transmission to a UE (e.g., in the SIM or UE specific RRC signalling). The parameter may indicate candidate positions of synchronization signal blocks (SSBs) within a discovery reference signal (DRS) measurement timing configuration (DMTC) transmission window within slots of a system frame (SFN). During the DMTC window, the gNB may perform a LBT procedure on an unlicensed carrier of the unlicensed spectrum to determine if the unlicensed carrier is available. When the LBT is successful (i.e., the unlicensed carrier is available), the gNB may encode a discovery reference signal (DRS) for transmission on the unlicensed carrier. The DRS may include one or more of the SSBs transmitted during the candidate positions that fall within the DRS.

  • Patent number: 11832266
    Abstract: A generation Node B (gNB) configured for operating in a fifth generation (5G) system encodes a downlink control information (DCI) for transmission to a user equipment (UE). For slot-less operation the DCI may indicate a set of values for a data channel scheduling gap and hybrid automatic repeat request—acknowledgement (HARQ-ACK) timing. The set of values may be defined for a symbol group including one or more symbols. The gNB may encode the data channel for transmission based on the one or more values.

  • Patent number: 11831479
    Abstract: Devices and methods of using xSS are generally disclosed. A UE receives an xPSS with (Nrep) symbols each with a subcarrier spacing of K×a PSS subcarrier spacing and a duration of a PSS symbol/K. PSD subcarriers surround the xPSS and the ZC sequence is punctured to avoid transmission on a DC subcarrier. Guard subcarriers separate the xPSS and PSD when the ZC sequence is less than the occupied BW of the xPSS and at least one element in the ZC sequence is punctured for xPSS symbol generation otherwise. One or more xSSSs and xS-SCHs may follow the xPSS. The xSS may be omnidirectional, each having a same xPSS and different xSSS or xS-SCH or a different xPSS and same xSSS or xS-SCH or beamformed, each having different xPSSs and xSSSs or xS-SCHs or a same xPSS and different xSSS or xS-SCH.

  • Patent number: 11825561
    Abstract: An apparatus for use in a UE includes processing circuitry coupled to a memory. To configure the UE for a 4-step random access procedure with a gNB in a 5G-NR network, the processing circuitry is to encode a first message for transmission to the gNB using a PRACH, the first message including a random access preamble. A second message received from the gNB in response to the first message is decoded. The second message includes a MAC RAR with an uplink (UL) grant and an indication of an LBT procedure type or a channel access and CP extension. An LBT procedure based on the LBT procedure type or the channel access and CP extension provided in the indication is performed. Data is encoded for transmission to the gNB based on successful completion of the LBT procedure, the transmission using a PUSCH, and a UL resource indicated by the UL grant.
