摘要： An apparatus for use in a UE includes processing circuitry coupled to a memory. To configure the UE for SSB processing in a 5G-NR network, the processing circuitry is to decode a MIB and a SIB received from a gNB. An RRC IE within the SIB is obtained. The RRC IE includes a bitmap associated with an SSB transmission pattern, where a length of the bitmap indicates a number of beams used within a cell of the gNB. SSB indices corresponding to candidate SSB positions within a discovery reference signal (DRS) transmission duration are determined based on the number of beams. Synchronization with the cell of the to gNB is performed using SSBs received within the DRS transmission duration, the SSBs selected based on the determined SSB indices.

摘要： An apparatus for use in a base station includes processing circuitry coupled to a memory. To configure the base station for channel access in a New Radio (NR) unlicensed (NR-U) network operating in an unlicensed spectrum, the processing circuitry is to perform an LBT procedure for a transmission occasion of a plurality of transmission occasions within a Discovery Measurement Timing Configuration (DMTC) window of a communication channel in the unlicensed spectrum. The transmission occasion is configured within a slot of a plurality of slots forming the DMTC window. A Discovery Reference Signal (DRS) is encoded for transmission to a UE on the communication channel, based on the successful completion of the LBT procedure. The DRS includes a PSS, a SSS, and a PBCH. A RACH procedure is performed with the UE, the RACH procedure initiated based on the PSS, the SSS, and the PBCH.

摘要： Systems and methods for interlace PUCCH transmission in 5G networks are described. The gNB sends an RRC message to a UE. The RRC message provides one or more PUCCH interlace allocations within a BW. Each PUCCH interlace allocation has a PUCCH format for each PUCCH interlace. Each PUCCH format contains a different PUCCH interlace index. The UE sends a PUCCH interlace in the BWP based on the PUCCH interlace allocation. A PUCCH in the allocated PUCCH interlace has a cyclic shift that is dependent on a resource block number in the allocated PUCCH interlace within the BWP.

摘要： Systems and methods for downlink transmission using a wideband unlicensed band carrier in 5G networks are described. The gNB determines, based on LBT, which LBT subchannel(s) in a BWP are available during a COT. The gNB transmits an indication of the available subchannels in DCI format 2_0 of a GC-PDCCH of one of the available subchannels and subsequently transmits a PDSCH using the available subchannel(s). The gNB may configure multiple opportunities during the COT and transmit the GC-PDCCH after the initial opportunity. The PDSCH is transmitted on all available subchannels during the COT and, during an initial portion of the COT, may transmit the PDSCH by puncturing symbols of the unavailable subchannels. The indication may include a bitmap of available subchannels or if the LBT outcome is not available, may indicate all or none of the subchannels or available or that the outcome is not available.

摘要： The present disclosure provides some embodiments that may facilitate hybrid grant-free UL transmission procedure, in which a user equipment (UE) may encode a first preamble and uplink (UL) control signaling for K repeated attempts of initial transmission; decode an acknowledgement (ACK) feedback or UL grant from the network node in response to receipt of the initial transmission(s); and encode UL data with or without a second preamble for subsequent grant-free UL transmissions. The present disclosure also provides some transmission schemes for UL control signaling for grant-free UL transmission.

摘要： Embodiments of the present disclosure describe apparatuses, systems, and methods for initialization of pseudo noise (PN) sequences for reference signals and data scrambling. Some embodiments may be to initialize the first M-sequence of the PN sequence with a fixed value; and initialize the second M-sequence of the PN sequence with a compressed value. Some embodiments may be to initialize the first M-sequence of the PN sequence with a fixed value; initialize the second M-sequence of the PN sequence with a part of the initialization parameters; and shift the PN sequence by another part of the initialization parameters. Some embodiments may be to initialize the first M-sequence of the PN sequence with a part of the initialization parameters; and initialize the second M-sequence of the PN sequence with another part of the initialization parameters. The embodiments may lead to a more efficient hardware design.
