[0114] Such as Image 6 As shown, the first embodiment of the present invention provides an uplink transmission method for the terminal side, including:

[0115] Step 11, when the terminal has uplink information that needs to be transmitted, send a first sequence at the position of the target time domain resource and the target frequency domain resource in the first time unit, wherein the first sequence is related to the terminal identity, and the first sequence A sequence is at least used to indicate that the terminal requests to allocate uplink resources for uplink transmission, wherein the length of the time unit is predefined as B1 subframes or B2 symbols, and both B1 and B2 are integers greater than or equal to 1.

[0116] Specifically, the first sequence is related to the terminal ID, and the terminal sending the first sequence is a terminal that needs to perform uplink transmission in a subsequent time unit, that is, when the terminal has uplink information that needs t...

[0140] In order to better describe the uplink transmission method, such as Figure 7 As shown, an uplink transmission method is used on the base station side, including:

[0141] Step 21: Detect the first sequence sent by the terminal at the position of the target time domain resource and the target frequency domain resource in the first time unit; wherein, the first sequence is related to the terminal identity, and the first sequence is at least used to indicate The terminal requests to allocate uplink resources for uplink transmission, the length of the time unit is predefined as B1 subframes or B2 symbols, and both B1 and B2 are integers greater than or equal to 1;

[0142] Step 22: Generate scheduling information for scheduling the terminals corresponding to the detected first sequence, and send an uplink scheduling grant bearing the scheduling information.

[0143] Further, the method also includes:

[0144] Allocate uplink transmission resources for subsequent time uni...

Abstract

Provided are an uplink transmission method and device. The uplink transmission method comprises: sending a first sequence at target time domain resource and target frequency domain resource locations in a first time unit when a terminal has uplink information to be transmitted, wherein the first sequence is related to an identifier of the terminal and is used at least for indicating that the terminal requests allocation of an uplink resource for uplink transmission, the length of the time unit is pre-defined as B1 sub-frames or B2 symbols, both B1 and B2 are integers greater than or equal to 1.

Description

technical field [0001] The present invention relates to the field of communication technology, 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 radio frame with a length of 10ms includes ten subframes of 1ms, each subframe is divided into time slots with a length of 0.5ms, and the TTI 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 and downlink transmission use d...
