Description

An uplink transmission processing method and device

technical field

Embodiments of the present invention relate to the field of communications technologies, and in particular, to a method and apparatus for processing uplink transmission.

Background technique

In recent years, wireless communication technology has developed rapidly, and modern society has entered the information age. All communication technologies are moving towards the goal of "high speed and low latency", and the increasingly stringent requirements for latency have also been explicitly written into the design standards of various communication technologies. 3GPP has established a project on "delay reduction technology". In order to distinguish it from legacy TTI, this project defines a "short transmission time interval" (sTTI), which is used to carry low-latency services. Two different lengths of sTTI are defined in the uplink, which are a 7-symbol sTTI and a 2(3)-symbol sTTI, respectively. For the 7-symbol sTTI, the uplink demodulation reference signal (DMRS) scheme of the legacy TTI can be used, and the uplink DMRS scheme for the 2(3) symbol sTTI has attracted 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}. Under the existing technical conditions, the uplink DMRS of the physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) in the legacy TTI fixedly occupies the fourth symbol of each time slot, if the short physical uplink of the uplink 2(3) symbols sTTI The shared channel (short Physical Uplink Shared Channel, sPUSCH) transmission also adopts the way that the uplink DMRS occupies one symbol fixedly, which will lead to a large uplink DMRS overhead, and the uplink DMRS overhead in a 2-symbol sTTI will be as high as 50%.

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