摘要： 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. The gNB may perform rate matching around the SSBs for a scheduled PDSCH based on the indicated parameter and transmit the rate-matched PDSCH.

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 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.

摘要： Systems, apparatuses, methods, and computer-readable media are provided for selecting a TCI-State for receiving downlink transmissions. In one example a processor/UE is configured to determine one or more candidate TCIs for a downlink slot; determine a scheduling offset between a physical downlink shared channel (PDSCH) and a physical downlink control channel (PDCCH); prioritize the candidate TCIs based on the scheduling offset; identify a highest priority candidate TCI; and select the highest priority candidate TCI for receiving the PDSCH.

摘要： An apparatus and system to provide an enhanced repetition mechanism for PUCCH coverage enhancement are described. The resource allocation and handling mechanisms for collisions with semi-static downlink symbols and invalid symbols are described. The UE receives a PUCCH resource in RRC signalling. The PUCCH resource includes a starting symbol and number of symbols of a PUCCH repetition in a slot and a repetition factor that indicates a number of repetitions. For contiguous repetitions, a repetition that crosses a slot boundary is dropped or segmented. A segmented portion equal to 3 symbols is not transmitted.

摘要： Embodiments of a User Equipment (UE), Next Generation Node-B (gNB) and methods of communication are generally described herein. The gNB may encode multiple candidate code-block groups to be available for a transmission in unlicensed spectrum, wherein one of the candidate code-block groups is to be transmitted based on a listen-before-talk (LBT) process. Each of the candidate code-block groups may be mapped to a different subset of channels in the unlicensed spectrum. The gNB may determine, based on one or more channel measurements, one or more of the channels that are available for the transmission. The gNB may select, as the candidate code-block group to be transmitted, a candidate code-block group for which the subset of the channels that is mapped to the selected candidate code-block group is included in the one or more channels that are available for the transmission.

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： A method and apparatus are provided for feedback for closed-loop transmitting with multiple transmit antenna elements and multiple receive antenna elements. A base station includes a codebook containing sets of weightings for the multiple transmit antenna elements, with each set of weightings identified by an index and the codebook known to the base station and a served mobile station (MS). The base station pre-codes pilot signals using a precoding matrix, preferably a unitary matrix, to produce pre-coded pilot signals, which precoding matrix may or may not be known to the MS and which precoding matrix may or may not be included in the codebook. The base station then transmits the pre-coded pilot signals to the MS via the multiple transmit antenna elements and, in response, receives an index to a set of weightings in the codebook for use in a subsequent transmission of a data stream.
