  • Publication number: 20240172243
    Abstract: Bandwidth part (BWP) switching for aperiodic sounding reference signal (SRS) transmissions is triggered via a downlink control information (DCI) format that does not include scheduling information. When a DCI format does not schedule a physical uplink shared channel (PUSCH) and does not include a channel state information (CSI) request, the UE may interpret one or more fields of the DCI format for the aperiodic SRS transmission.

  • Publication number: 20240172136
    Abstract: 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.

    Abstract: An apparatus and system for aperiodic sounding reference signals (SRS) transmission are described. Downlink control information (DCI) format 2_3 indicates a Transmission Configuration Indicator (TCI) state for beam indication for transmission of an SRS triggered by the DCI. An explicit field is added to the DCI to indicate the TCI state or the TCI state of the scheduling carrier used to transmit the DCI is used for the SRS. The TCI state indicates a joint uplink/downlink TCI state or a separate uplink or downlink TCI state. The DCI indicates an available slot to use for the SRS explicitly in a DCI field or implicitly based on the component carrier used for transmission of the SRS, the slotOffset parameter, or the first available slot.

  • Patent number: 11985011
    Abstract: Various embodiments herein provide techniques for minimum mean-square error interference rejection combining (MMSE-IRC) processing of a received signal, distributed between a baseband unit (BBU) and a remote radio unit (RRU). The RRU may perform a first phase of processing based on an extended channel that includes a channel of one or more user equipments (UEs) served by the RRU and interference samples that correspond to other cells or additive noise. The first phase may include scaling the interference samples by a scaling coefficient to obtain a modified extended channel, and performing maximum ratio combining (MRC) on the modified extended channel to obtain a processed signal. The RRU may send the processed signal to the BBU for the second phase of processing. The second phase of processing may include regularized zero forcing to remove interference. Other embodiments may be described and claimed.

  • Publication number: 20240155637
    Abstract: A user equipment (UE) configured for operation in a fifth-generation (5G) new radio (NR) (5G-NR) system may decode a downlink control information (DCI) format comprising one of DCI format 0_1 and DCI format 0_2. When the DCI format does not schedule a physical uplink shared channel (PUSCH) and does not trigger a sounding reference signal (SRS) transmission, and when the DCI format at least triggers a channel state information (CSI) request including at least one of a CSI reference signal (CSI-RS) operation, a CSI interference measurement (CSI-IM), and a CSI report transmission, the UE may interpret one or more fields of the DCI format that would normally be used for PUSCH scheduling and/or SRS triggering as indicating additional information or parameters for the triggered CSI request. The UE may perform the triggered CSI request using at least the information in the one or more repurposed fields of the DCI.

  • Publication number: 20240154723
    Abstract: A computer-readable storage medium stores instructions to configure a UE for operation in a 5G NR and beyond wireless network and to cause the UE to perform operations. The operations include encoding a data bitstream to generate a plurality of code blocks. Code block interleaving of a subset of code blocks of the plurality of code blocks is performed to generate an interleaved bitstream. The interleaved bitstream is modulated using a discrete Fourier transform-spread-orthogonal frequency division multiplexing (DFT-s-OFDM) to generate multiple sets of time-domain samples. The operations further include causing transmission of the multiple sets of time-domain samples.

The operations include performing measurements on a plurality of SS/PBCH blocks to determine a set of preferred SS/PBCH beams. A MAC control element (CE) is encoded for transmission to a base station. The MAC CE includes at least one preferred beam pair for the multi-TRP operation. The at least one preferred beam pair includes a pair of preferred SS/PBCH beams selected from the set and corresponding to a pair of UE antenna panels. Downlink data received by the pair of UE antenna panels during the multi-TRP operation is decoded. The downlink data is received via reception beams corresponding to the pair of preferred SS/PBCH beams.
