Abstract
A method for transmitting Physical Uplink Shared Channel (PUSCH) performed by a User Equipment (UE) in a wireless communication system may include receive downlink control information (DCI) for uplink (UL) transmission scheduling; and performing codebook based PUSCH transmission based on precoding information included in the DCI.
Claims14
A method for codebook-based transmission of a Physical Uplink Shared Channel, PUSCH, in a wireless communication system, the method performed in a User Equipment (UE) comprising:
- receiving, from a network node, configuration information, wherein the configuration information includes i) rank restriction information related to subset restriction of a codebook for PUSCH transmission and ii) waveform information on which waveform to be used for PUSCH transmission;
- receiving, from the network node, downlink control information (DCI) for PUSCH transmission, wherein the DCI includes a bit field for indicating rank information and precoding matrix information;
- and
- performing the codebook-based transmission of the PUSCH using a precoder,
- wherein the precoder is selected from a subset of the codebook based on the bit field of the DCI, and
- wherein the subset of the codebook is determined based on the rank restriction information and the waveform information.
A User Equipment (UE) for codebook-based transmission of a Physical Uplink Shared Channel, PUSCH, in a wireless communication system, the UE comprising:
- a radio frequency, RF, transceiver for transmitting and receiving a radio signal;
- and
- a processor (1821) for controlling the RF transceiver,
- wherein the processor is configured to:
- receive, from a network node, configuration information for a codebook, wherein the configuration information includes i) rank restriction information related to subset restriction of a codebook for PUSCH transmission and ii) waveform information on which waveform to be used for PUSCH transmission;
- receive, from the network node, downlink control information (DCI) for PUSCH transmission, wherein the DCI includes a bit field for indicating rank information and precoding matrix information;
- and
- perform the codebook-based transmission of the PUSCH using a precoder,
- wherein the precoder is selected from a subset of the codebook based on the bit field of the DCI, and
- wherein the subset of the codebook is determined based on the rank restriction information and the waveform information.
A device comprising:
- one or more memories;
- and
- one or more processors functionally connected to the one or more memories,
- wherein the one or more processors are configured to:
- receive, from a network node, configuration information for a codebook, wherein the configuration information includes i) rank restriction information related to subset restriction of a codebook for PUSCH transmission and ii) waveform information on which waveform to be used for PUSCH transmission;
- receive, from the network node, downlink control information, DCI, for PUSCH transmission, wherein the DCI includes a bit field for indicating rank information and precoding matrix information;
- and
- perform the codebook-based transmission of the PUSCH using a precoder,
- wherein the precoder is selected from a subset of the codebook based on the bit field of the DCI, and
- wherein the subset of the codebook is determined based on the rank restriction information and the waveform information.
