Abstract

Provided in the present disclosure are an uplink transmission method and apparatus. The uplink transmission method comprises: receiving a first downlink control channel, the first downlink control channel being used for carrying scheduling information of a first uplink shared channel; determining, on the basis of the scheduling information carried by the first downlink control channel, a first frequency domain resource for transmitting the first uplink shared channel; determining a second frequency domain resource which is used for transmitting a pilot frequency according to an instruction of a pre-agreed upon and / or configured signaling; transmitting the first uplink shared channel on the first frequency domain resource, and transmitting the pilot frequency of the first uplink shared channel on the second frequency domain resource; the size of the second frequency domain resource being greater than or equal to the size of the first frequency domain resource.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to an uplink transmission method and device. Background technique [0002] The existing LTE FDD (Frequency Division Duplex) system uses a frame structure (frame structure type 1, referred to as FS1), and its structure is as follows figure 1 shown. In the FDD system, different carrier frequencies are used for uplink and downlink transmission, and the same frame structure is used for both uplink and downlink transmission. On each carrier, a 10ms-long wireless frame contains 10 1ms subframes, each subframe is divided into 0.5ms-long time slots, and the transmission time interval (TTI, Transmission TimeInterval) duration of uplink and downlink data transmission is 1ms. [0003] The existing LTE TDD (time division duplex) system uses a frame structure (frame structure type 2, referred to as FS2), and its structure is as follows figure 2 shown. In a TDD system, uplink...
