  • METHOD FOR DIFFERENTIATING MULTIPLE PHYSICAL DOWNLINK SHARED CHANNEL (PDSCH) TRANSMISSION SCHEMES
    Publication number: 20220104237
    Abstract: A method for differentiating multiple Physical Downlink Shared Channel (PDSCH) transmission schemes. In a non-limiting example, the PDSCH transmission schemes include a spatial multiplexing transmission scheme, a frequency multiplexing transmission scheme, a slot-based time multiplexing transmission scheme, and a mini-slot-based time multiplexing transmission scheme. In examples discussed herein, a User Equipment (UE) can be configured to differentiate the PDSCH transmission schemes based on information indicated in Downlink Control Information (DCI) for scheduling a PDSCH transmission, information signaled to the UE via a higher layer configuration, and/or capability signaling indicated from the UE to a network. By differentiating the PDSCH transmission schemes, the UE can efficiently receive a data transmission(s) from multiple Transmission/Reception Points (TRPs).

  • CSI FEEDBACK FOR DATA TRANSMISSION OVER MULTIPLE TRANSMISSION POINTS
    Publication number: 20210391967
    Abstract: Systems and methods for Channel State Information (CSI) feedback for multiple Transmission Points (TRPs) in a cellular communications network are disclosed. Embodiments of a method of operation of a wireless device and corresponding embodiments of a wireless device are disclosed. In some embodiments, a method performed by a wireless device for CSI feedback comprises receiving a configuration comprising N Non-Zero Power (NZP) CSI Reference Signal (CSI-RS) resources each associated with a different one of N TRPs or N sets of NZP CSI-RS resources each associated with a different one of the N TRPs. The method further comprises receiving a request for CSI feedback based on the configuration, selecting a preferred subset of the NZP CSI-RS resources comprised in the N NZP CSI-RS resources or the N sets of NZP CSI-RS resources, and reporting, to a base station, CSI based on the selected preferred subset of the NZP CSI-RS resources.

  • Network Node, User Equipment and Methods Therein to Enable the UE to Determine a Precoder Codebook
    Publication number: 20210367646
    Abstract: A method performed by a base station of enabling a User Equipment (UE) to determine a precoder codebook in a wireless communication system is provided. The base station transmits, to the UE, information regarding precoder parameters enabling the UE to determine the precoder codebook. The precoder parameters are associated with a plurality of antenna ports of the base station. The precoder parameters relate to a first dimension and a second dimension of the precoder codebook. The plurality of antenna ports comprises a number of antenna ports that is a function of a number of antenna ports in the first dimension, and a number of antenna ports in the second dimension.

  • Codebook subset restriction signaling
    Patent number: 11139872
    Abstract: A network node signals to a wireless communication device which precoders in a codebook are restricted from being used. The network node in this regard generates codebook subset restriction signaling that, for each of one or more groups of precoders, jointly restricts the precoders in the group by restricting a certain component (e.g., a certain beam precoder) that the precoders in the group have in common. This signaling may be for instance rank-agnostic signaling that jointly restricts the precoders in a group without regard to the precoders' transmission rank. Regardless, the network node sends the generated signaling to the wireless communication device.

    Abstract: Methods and apparatus in a fifth-generation wireless communications network, including an example method, in a wireless device, that includes determining a reporting quality threshold for a parameter related to channel state information (CSI); performing a measurement for each of a plurality of beams from a first predetermined set of beams for evaluation; evaluating the measurement for each of the plurality of beams against the reporting quality threshold; discontinuing the performing and evaluating of measurements in response to determining that the reporting quality threshold is met for one of the beams, such that one or more beams in the first predetermined set of beams are not measured and evaluated; and reporting, to the wireless communications network, CSI for the one of the beams.

  • Masked beamforming
    Patent number: 10340993
    Abstract: There is disclosed a method of operating a transmitter arrangement for a wireless communication network, the transmitter arrangement adapted for beamforming. The method comprises determining a maximum power level mask for the power of transmission and/or beams in a critical angular interval, the maximum power level mask covering at least the critical angular interval and controlling beamforming based on the maximum power level mask.

  • Precoding a transmission from a one-dimensional antenna array that includes co-polarized antenna elements aligned in the array's only spatial dimension
    Patent number: 10312983
    Abstract: A transmitting radio node (10) precodes a transmission from a one-dimensional antenna array (12) to a receiving radio node (50). The array (12) includes co-polarized antenna elements (14) aligned in the array's only spatial dimension. The transmitting radio node (10) precodes the transmission from each of different subarrays (34a, 34b) of the antenna elements (14) using a coarse-granularity precoder that is factorizable from a multi-granular precoder targeting the given spatial dimension of the array (12) at different granularities, so as to virtualize the subarrays (34a, 34b) as different auxiliary elements (38a, 38b). The transmitting radio node (10) also precode the transmission from the different auxiliary elements (38a, 38b) using one or more finer-granularity precoders that are also factorizable from the multi-granular precoder. In this case, the coarse granularity precoders and the one or more finer-granularity precoders are represented within one or more codebooks (26) used for said precoding.
