Technical field

The embodiments of the present invention relate to the field of communications technologies, and in particular, to an uplink transmission processing method and apparatus.

Background technique

In recent years, wireless communication technology has developed rapidly, and modern society has entered the information age. All kinds of communication technologies are moving toward the goal of "high rate, low latency", and the increasingly strict requirements for delay are also explicitly written into the design standards of various communication technologies. 3GPP has established a "reduction delay technology". In order to distinguish it from legacy TTI, the project defines a "short transmission time interval" (sTTI) for carrying low-latency services. The uplink defines two different lengths of sTTI, which are 7 symbols sTTI and 2 (3) symbols sTTI, respectively. For the 7-symbol sTTI, the legacy Demodulation Reference Signal (DMRS) scheme of the legacy TTI can be used, and the uplink DMRS scheme for the 2(3) symbol sTTI is getting more and more attention.

FIG. 1 is a schematic diagram of the structure of an uplink 2 (3) symbol sTTI frame. As shown in FIG. 1 , the structure of the uplink 2 (3) symbol uplink sTTI is fixed in the format of {3, 2, 2, 2, 2, 3}. In the prior art, the uplink DMRS of the physical uplink shared channel (PUSCH) in the legacy TTI is fixed to occupy the fourth symbol of each time slot, and if the uplink 2 (3) symbol is short physical uplink of the sTTI The short physical uplink shared channel (sPUSCH) transmission also uses the uplink DMRS to occupy one symbol in a fixed manner, which will result in a larger uplink DMRS overhead. The uplink DMRS overhead in the 2-symbol sTTI will be as high as 50%.

Therefore, how to propose an uplink transmission processing method to reduce the uplink DMRS overhead is an important issue to be solved in the industry.
