Description

Channel measuring method and user equipment

Technical field

The present embodiments relate to channel measurement technology more particularly to a kind of channel measuring methods and user equipment.

Background technique

(new radio, NR) middle support of newly eating dishes without rice or wine of 5th third-generation mobile communication technology (5th-Generation, 5G) is based on The uplink transmission mode of code book.Base station can configure at least one detection reference signal (Sounding by high-level signaling Reference Signal, SRS) resource.SRS resource that user equipment (User equipment, UE) is configured according to base station and Indication signaling sends SRS in the SRS resource.Base station receives and measures the SRS of user equipment transmission.When the user is dispatched in base station When carrying out upstream data transmission, it will be referred to by Downlink Control Information (DCI Downlink control information, DCI) Show that SRS resource indicates (SRS resource indication, SRI), transmits the number of plies (Transmission rank Indication, TRI) and transmitting pre-encoding matrix (Transmission precoding matrix indication, TPMI).UE is determined based on the instruction information sends the transmission number of plies and precoding mode used in data.TRI and TPMI can be with Combined coding, that is to say, that the transmission number of plies and precoding can be indicated by some state in one DCI field of instruction simultaneously Matrix information.The transmission number of plies can be selected and be indicated from set { 1,2,3,4 }, and TPMI is based on table 1- table 4 and is selected and referred to Show.

The code book of 1. 1 layers of table transmission

The code book of 2. 2 layers of table transmission

The code book of 3. 3 layers of table transmission

The code book of 4. 4 layers of table transmission

For each number of plies, there are three types of relevant ability, every kind of relevant ability all corresponds at least one pre-coding matrix.Such as In table 1, there are 16 pre-coding matrixes that can be selected for completely relevant, there are 8 pre-coding matrixes can be with partially coherent It is selected, has 4 pre-coding matrixes that can be selected for incoherent.UE reports three kinds of relevant abilities, and base station passes through RRC signaling The limitation of code book subset, codebook subset limitation are used to indicate the range of TPMI selection code book.Codebook subset limitation includes three State indicates respectively completely relevant, partially coherent and incoherent.Specific indicating means is: one of state is used to indicate Codebook set indicated by TPMI includes be concerned with completely corresponding code book, the corresponding code book of partially coherent and incoherent corresponding code This；It includes the corresponding code book of partially coherent and incoherent corresponding code that one state, which is used to indicate codebook set indicated by TPMI, This；It includes incoherent corresponding code book that one state, which is used to indicate codebook set indicated by TPMI,.It can only refer in three states Show one of state.Partially coherent transmittability is reported for UE, base station will cannot indicate code book collection indicated by TPMI It closes comprising the corresponding code book that is concerned with completely；Incoherent transmittability is reported for UE, base station cannot indicate indicated by TPMI Codebook set include to be concerned with completely corresponding code book and the corresponding code book of partially coherent.In this way, TRI and TPMI combined coding Field size will change according to the instruction of three states.

When 4 relative user equipment of table 1- table has the transmission of 4 antennas, and sending waveform used in data is before band recycles Orthogonal frequency division multiplexing multiple access (Cyclic Prefix-Orthogonal Frequency the Division Multiple, CP- sewed OFDM) situation.When having the transmission of 2 antennas for user equipment, and sending waveform used in data is CP-OFDM situation, Transmitting the number of plies is 1 or 2, and TPMI is based on table 5 and is selected and indicated.

2 antenna codebooks of the table 5. for CP-OFDM waveform

The case where for using discrete Fourier transform to extend OFDM (DFT-Spread-OFDM, DFT-S-OFDM), transmission The number of plies is only 1, and when user equipment has the transmission of 2 antennas, TPMI is based on table 6 and is selected and indicated, when user equipment has When standby 4 antennas are sent, TPMI is based on table 7 and is selected and indicated.Meanwhile the network equipment can indicate to transmit by high-level signaling The limitation of the number of plies, the instruction for carrying out the transmission number of plies and TPMI for limiting a subset from the set of the maximum transmitted number of plies, this Sample can reduce the signaling overheads of the transmission number of plies and TPMI instruction.
