Embodiment 1
[0082] An embodiment of the present invention provides a method for reporting CSI information, which can be applied to a terminal to enable the terminal to perform data transmission with a base station, such as image 3 As shown, the method can be described as follows.
[0083] S11: The terminal receives the uplink channel resource configuration signaling and / or DMRS configuration signaling sent by the base station, and determines the mapping symbol set according to the uplink channel resource configuration signaling and / or DMRS configuration signaling; wherein, the DMRS configuration signaling is used to indicate The number of DMRS configured by the system for the uplink channel, and the time-frequency position of the OFDM symbol occupied by each DMRS in the time-frequency resource carrying the uplink channel. The uplink channel resource configuration signaling is used to indicate the uplink channel For the occupied time-frequency resource, the set of mapped symbols is a set ...
Embodiment 2
[0132] Such as Figure 6 As shown, the embodiment of the present invention provides a method for receiving CSI information, which can be applied to a base station, and the method includes the following steps:
[0133] S21: The base station sends uplink channel configuration signaling and / or DMRS configuration signaling to the terminal; wherein, the DMRS configuration signaling is used to indicate the number of DMRS configured by the system for the uplink channel, and the time-frequency resource of each DMRS for carrying the uplink channel The time-frequency position of the orthogonal frequency division multiplexing OFDM symbol occupied in the , and the uplink channel resource configuration signaling is used to indicate the time-frequency resource occupied by the uplink channel.
[0134] Specifically, the uplink channel configuration signaling and / or DMRS configuration signaling may instruct the terminal to configure a pre-DMRS and a set of additional DMRS on the PUSCH channel,...
Embodiment 3
[0141] Based on the same inventive concept, an embodiment of the present invention provides a terminal, which can be used to execute such as image 3 The method for reporting CSI information shown, such as Figure 7 As shown, the terminal includes a receiver 31 , a processor 32 and a transmitter 33 .
[0142] Considering that in practical applications, the receiver 31 and the transmitter 32 are usually set in the same device, such as a transceiver, therefore Figure 7 Take these two components as components in the transceiver as an example.
[0143] In addition, the terminal may also include a memory 34, Figure 7 shown in dotted line. The memory 34 can be used to store various data in the terminal, such as storing CSI information and the like.
[0144] The receiver 31 may be configured to receive uplink channel resource configuration signaling and / or demodulation reference signal DMRS configuration signaling sent by the base station, and determine a mapping symbol set acc...
