  • Publication number: 20210359742
    Abstract: Methods, systems, and circuitries for configuring, measuring, and reporting channel state information are described. In one embodiment, an apparatus for a user equipment device (UE) includes processors configured to determine first channel state information (CSI) reference signal (RS) resource associated with a serving cell for the UE and determine a second CSI-RS resource associated with a non-serving cell for the UE. A first reference signal received in the first CSI-RS resource and a second reference signal received in the second CSI-RS resource are measured. First report quantities characterizing a channel between the UE and the serving cell are calculated based on the measurement of the first reference signal and second report quantities characterizing a channel between the UE and the non-serving cell are calculated based on the measurement of the second reference signal. The first and second report quantities are reported to the serving cell.

  • Publication number: 20210289446
    Abstract: This disclosure proposes to use multiple power control loops in the uplink. Each power control loop may be associated with a respective antenna beam transmitted from an antenna array of the electronic device (e.g. UE) in the uplink. For example, a beam (or uplink signal) may be associated with 1, 2 or even more MIMO layer. Hence, in this latter case, each power control loop may be associated with a respective set of one or more MIMO layers. This concept is application to open-loop, closed-loop power control or both.

  • Publication number: 20210175950
    Abstract: User equipment (UE) includes processing circuitry coupled to memory. To configure the UE for channel state information (CSI) reporting in a 5G network, the processing circuitry is to decode a radio resource control (RRC) configuration message, the RRC configuration message including first configuration information to configure determination of channel quality information (CQI), a rank indicator (RI), and a precoding matrix indicator (PMI) for the CSI reporting. Second configuration information is decoded to configure codebook parameters for a high spatial resolution codebook associated with the PMI. A precoding matrix is determined based on the first configuration information, where a number of coefficients in at least one coefficient vector of the precoding matrix is configured using the second configuration information. CSI is encoded for transmission to a base station, the CSI including the RI and the PMI associated with the determined precoding matrix.

  • Publication number: 20210111930
    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.
