Embodiment 1
[0041] An embodiment of the method for delivering measurement reference signal configuration information in the present invention may include: generating at least two downlink control signaling DCIs, each of the at least two DCIs includes measurement reference signal SRS configuration information bits; The subframe sends the at least two DCIs to the terminal, so as to jointly indicate the SRS configuration through the SRS configuration information bits in the at least two DCIs.
[0042] see figure 1 , the specific steps may include:
[0043] 110. The wireless access device generates at least two DCIs, where each DCI of the at least two DCIs includes measurement reference signal SRS configuration information bits;
[0044] In practical applications, the wireless access device can specify SRS configuration parameters to the terminal when it needs to measure the wireless channel between it and a certain terminal (such as measuring channel quality); The specified SRS configurati...
Embodiment 2
[0072] To facilitate a better understanding of the technical solutions of the embodiments of the present invention, a more detailed description will be given below by taking the manner in which the wireless access device jointly indicates the SRS configuration with two DCI SRS configuration information bits in different formats as an example.
[0073] 201. The wireless access device generates two DCIs, and each of the at least two DCIs includes measurement reference signal SRS configuration information bits;
[0074] Wherein, the information formats of the above two DCIs may be the same or different.
[0075] In practical applications, when the wireless access device needs to measure the channel quality of the current wireless channel between itself and the terminal, it can specify SRS configuration parameters to the terminal; and the terminal can use the SRS configuration parameters specified by the wireless access device to send SRS.
[0076] The wireless access device can ...
example ( 1
[0109] For example, if the DCIs of format 1a and format4 are sent in the same subframe, the sending and receiving parties can perform processing in the following manner. The wireless access device adopts joint coding for 1 bit in the DCI of Format 1a and 2 bits in the DCI of Format 4, and the mapping relationship between coding and SRS configuration can be shown in Table 4:
