  • Extended physical broadcast channel design for 5G standalone system
    Patent number: 10855407
    Abstract: Devices and methods of receiving a PDCCH-less xSIB are generally described. A UE receive a xPBCH that occurs in a 0th or a 25th subframe and an ePBCH in an ePBCH transmission block. The ePBCH has the xSIB and is received on different Tx beams. The ePBCH spans consecutive symbols on the same subcarrier and with the same ePBCH symbol. The frame number, subframe number and symbol number of the ePBCH is dependent on a subframe number and symbol number of the xPBCH. The number of beams received for a particular symbol is dependent on a total number of beams, a beam sweeping time for the beams and a transmission periodicity of the xPBCH and ePBCH. The UE also uses different OCCs to demodulate a DMRS from different APs, in a same PRB as the ePBCH.

Rx beams are trained based on multiple instances of each BRS and the eNB supplies selection criteria for the BRSRP report. The Rx beams are refined based on BRRS and the second active link is dependent on BRRSRP or CSI feedback. When configured for dual beam operation, the BRSRP feedback corresponds to BRSRP value pairs and dual Rx beams associated with a pair of serving link IDs are used.

  • PBCH CONTENT FOR NR UNLICENSED
    Publication number: 20190342826
    Abstract: Systems and methods of providing timing information for initial access in an unlicensed band are described. A UE monitors a new radio discovery signal (NRDS-U) window in an unlicensed band for a DRS transmission that is constrained to be transmitted within the NRDS-U window. The UE determines initial access information, including an offset that indicates when the DRS transmission occurs within the NRDS-U window, and engages in initial access dependent on the offset. The offset is from a radio frame or half radio frame boundary or the start of the NRDS-U window. The offset is indicated in three least/most significant bits an SSB index or from an s1-offset field in a MIB of the SSB. When the base station uses a DFS channel, the base station transmits a periodic signal to emulate a radar signal.
