摘要： A method for generating a variable reference signal is provided. The method comprises initializing a scrambling sequence generator at the start of a 10 millisecond (ms) radio frame. The variable reference signal is generated for the radio frame based on different antenna ports, sequence length per antenna port and an initialization seed constructed with a specified equation. Additionally, the variable reference signal is initialized at the start of a 1 ms radio subframe based on a constructed initialization seed.

摘要： Embodiments of a user equipment (UE) configured for new-radio (NR) operations in a fifth-generation (5G) system (5GS) may be configured to detect a downlink-control information (DCI) format that includes a one-shot hybrid automatic repeat request acknowledgement (HARQ-ACK) request field and a frequency domain resource assignment field (FDRA). The one-shot HARQ-ACK request field may indicate whether one-shot HARQ-ACK feedback is triggered. The UE may decode the FDRA field to determine whether the FDRA field indicates a valid frequency resource or whether the FDRA field indicates a special value and may also be configured to determine whether or not a physical downlink shared channel (PDSCH) is scheduled by the DCI format and whether or not secondary cell (SCell) dormancy switching is triggered based on both the one-shot HARQ-ACK request field and the FDRA field. The UE may also encode a HARQ-ACK transmission on a physical uplink control channel (PUCCH). The HARQ-ACK transmission may be encoded to include HARQ-ACK feedback for PDSCH transmissions for all HARQ processes of a cell when the one-shot HARQ-ACK feedback is triggered.

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： A user equipment (UE) for operation in a fifth-generation new radio (5G NR) network may be configured with two or more secondary cells (SCells) of a group of SCells. In these embodiments, the UE may monitor a physical downlink control channel (PDCCH) for detection of a downlink control information (DCI) format 1_1. The UE may interpret the DCI format 1_1 as indicating SCell dormancy, rather than scheduling a physical downlink shared channel (PDSCH) reception, if the UE is configured with resourceAllocationType1 and if all bits of a frequency domain resource assignment field in the DCI format 1_1 are equal to 1. For SCell dormancy, the UE may interpret fields of the DCI format 1_1 as a bitmap for SCell dormancy indication and either activate or deactivate a downlink bandwidth part (DL BWP) for an SCell of the group of configured SCells when indicated by the bitmap.

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： A sounding reference signal transmission method which is efficient in an uplink wireless telecommunications system using a multiple antenna technique and sounding reference signal hopping. A terminal using the multiple antenna technique is equipped with a plurality of antennas, and a base station receives the sounding reference signal transmitted from these antennas and estimates the uplink channel state of each antenna. Moreover, the sounding reference signal performs frequency hopping so that the base station determines the channel condition for the entire bandwidth to which data is transmitted in the uplink system. The sounding reference signal is transmitted through an antenna pattern in which the sounding reference signal can be transmitted through the entire data transmission bandwidth of the uplink system for each antenna of the terminal without additional overhead in this environment.
