    摘要： A computer-readable storage medium stores instructions to configure a UE for a power control procedure in a 5G NR and beyond wireless network. The instructions cause the UE to perform operations including decoding RRC signaling received from a base station. The RRC signaling includes one or more open-loop power control parameters. A reference signal received power (RSRP) is determined. The RSRP is associated with a reference signal received from the base station using a receive beam. A path loss associated with the receive beam is determined based on the RSRP. A transmission (Tx) power is determined using the one or more open-loop power control parameters and the path loss. The Tx power is adjusted based on a power threshold shared between at least two antenna panels of a plurality of antenna panels. Uplink data is encoded for transmission to the base station according to the adjusted Tx power.

    摘要： A computer-readable storage medium stores instructions for execution by one or more processors of a UE to configure the UE for enhanced SRS power control in a 5G NR network, and to cause the base station to decode RRC signaling received from a base station of a plurality of base stations. The RRC signaling includes an SRS resource configuration. The SRS resource configuration includes at least one SRS resource set configured with a plurality of closed-loop power control states associated with a coherent joint transmission by the UE to the plurality of base stations. A plurality of SRSs is encoded for transmission to the plurality of base stations based on the SRS resource configuration. The plurality of SRSs including a first SRS encoded for transmission to the base station.

    摘要： Systems and methods for transmission of full power uplink transmission in 5G networks are described. The gNB provides TPMI precoding information in DCI of a PDCCH in which the field size for precoding information and number of layers are fixed irrespective of the SRI. The gNB indicates in RRC signaling the use of codebook-based transmission for UL. If different SRS resources with different number of antenna ports are configured, the bitwidth of the SRI field is the maximum number of ports among the configured SRS resources in an SRS resource set with usage set to ‘codebook’. If the number of ports for a configured SRS resource in the set is less than the maximum number of ports, the most significant bits of the field have a value of ‘0’. The bitwidth is dependent on UE coherence capabilities and a maxrank of the UE.

    摘要： An apparatus of user equipment (UE) includes processing circuitry coupled to a memory, where to configure the UE for DMRS processing in an NR network, the processing circuitry is to generate a plurality of binary sequences of length L, the binary sequences being arranged according to a signal quality metric. A set of CGSs is generated using the binary sequences, based on minimizing cross-correlation between subsets of binary sequences of different lengths selected from the plurality of binary sequences. A CGS is selected from the set of CGSs as a DMRS, based on uplink PRB resource allocation. The DMRS is encoded for transmission, where the encoding includes BPSK modulation and discrete Fourier transformation (DFT) spreading of the DMRS.
