摘要： One apparatus for providing high-resolution CSI feedback includes a processor and a radio transceiver. The processor computes sets of amplitude and phase parameters for one or more matrices corresponding to a CSI codebook. Here, each matrix corresponds to one transmission layer of a multiple-layer transmission, where each matrix is comprised of one or more column vectors. The radio transceiver sends indications of the sets of amplitude and phase parameters to one or more network entities is a mobile communication network.

摘要： A configuration of a set of transmission configuration indicator (TCI) states associated with a serving cell is received for a physical downlink shared channel (PDSCH) transmission, each TCI state of the set of TCI states corresponds to one or more parameters for configuring a quasi-co-location (QCL) relationship between one or more downlink reference signals and one or more downlink reference signal ports associated with the PDSCH transmission. A physical downlink control channel (PDCCH) including a downlink control information (DCI) scheduling a PDSCH for the PDSCH transmission is received. A medium access control-control element (MAC-CE) is received indicating at least two configured TCI states of the set of TCI states. The at least two configured TCI states are selected based on a timing offset between a reception of the PDCCH and a reception of the PDSCH satisfying a threshold.

摘要： A transceiver can transmit a codebook subset restriction configuration including a set of restricted beams. A channel state information report including a plurality of sets of quantized coefficients based on the codebook subset restriction configuration can be received. A set of quantized weights can be based on a least a Fourier transform of a set of quantized coefficients of the particular restricted beam. The plurality of sets of quantized coefficients can be based on quantized weights of the particular restricted beam satisfying a constraint. The plurality of sets of quantized coefficients can be further based on a set of coefficients quantized to determine the plurality of sets of quantized coefficients. The set of coefficients can be generated by transforming a set of beam weights from a frequency domain to a time domain, where the beam weights correspond to a transmitted beam.

摘要： A configuration parameter for a CSI resource set can be received. The configuration parameter can indicate a first offset applicable to the CSI resource set. A control channel containing DCI with a downlink DCI format can be received in a first downlink slot. The DCI can indicate a second offset applicable to the CSI resource set. A second downlink slot in which the CSI resource set is transmitted by a network entity for an active BWP can be determined based on the first offset and the second offset.

摘要： For Type-II codebook compression, methods, apparatus, and systems are disclosed. One apparatus includes a transceiver that receives a reference signal and a processor that identifies a set of taps over a layer based on the reference signal, where the set of taps are selected from a set of Nsb indices, the value Nsb representing a number of sub-bands. The processor generates a combinatorial codeword representing the set of taps. The processor reports the combinatorial codeword for the set of taps as part of a CSI feedback report.

摘要： The generation of a channel state information report is provided. The generation includes transmitting reference signals to a user equipment, and receiving a reported set of quantized weighting coefficients, each of the weighting coefficients corresponding to a respective beam index and a respective tap index, where a set of beams based on the received reference signals is selected, where each of the beams corresponds to a discrete Fourier transform vector, and where each of the beams has a corresponding beam index. The tap index corresponds to a member of a Fourier basis set, where at least two subsets of the reported set of weighting coefficients are quantized according to separate quantization procedures.

摘要： Generating a channel state information (CSI) feedback report is provided. A set of reference signals is received (1502). A set of entries that are included in the CSI feedback report is computed (1504). Each entry has a most significant bit, and one or more remaining bits, where an order of each of the entries in the CSI feedback report are arranged based upon a bit level classification of the entries (1508). A value of the most significant bit of each of the entries is identified, and the entries, which have a most significant bit value corresponding to a higher bit value have the remaining bits arranged in a group that is positioned in the CSI feedback report prior to a group of tire remaining bits of the entries, which have a most significant bit value corresponding to a lower bit value (1510).

摘要： According to a possible embodiment, a control channel can be received in a first downlink slot. The control channel can contain DCI with a downlink DCI format. The DCI can contain a CSI report trigger that triggers a CSI report. The DCI can schedule PDSCH transmissions repeated a number of times in a set of downlink slots. Each PDSCH transmission of the repeated PDSCH transmissions can be in a separate downlink slot. A CSI report can be generated in response to receiving the CSI report trigger. At least one uplink resource to transmit the generated CSI report can be determined. The at least one uplink resource can be determined based on the number of repeated PDSCH transmissions. The generated CSI report can be transmitted in the determined at least one uplink resource.
