Problems solved by technology

[0004] However, the SR channel in the prior art is only used as a scheduling request. When the clock deviation between the user terminal (UE) and the base station or the movement of the UE occurs, there will be a hidden danger of uplink out-of-sync, which will affect the stability of uplink services.

Embodiment Construction

[0036] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0037] figure 2 It is a flow chart of an uplink service sending method in a multi-subband system provided by an embodiment of the present invention, as shown in figure 2 shown, including:

[0038] S1. Obtain an uplink synchronization signal;

[0039] S2. Add the uplink synchronization signal at the physical channel position of the uplink pilot time slot of the first subband or the second subband starting from the non-resident subband of the multi-subband system;

[0040] S3. Send the uplink synchronization signal when the uplink service is triggered.

[0041] In S1, the uplink synchronization signal is the uplink synchronization resource configured in the channel of ...

Abstract

The present invention provides a method and device for sending uplink services in a multi-subband system. The method includes: S1. Obtaining an uplink synchronization signal; S2. Add the uplink synchronization signal to the position of the physical channel of the uplink pilot time slot of the band or the second subband; S3. When the uplink service is triggered, send the uplink synchronization signal. The present invention adds an uplink synchronization signal to the physical channel position of the uplink pilot time slot of the first subband or the second subband starting from the non-resident subband of the multi-subband system, so that the mobile user will not experience uplink out-of-sync , to ensure the stability of the uplink business.

Description

technical field [0001] The present invention relates to the technical field of communications, and more specifically, to a method and device for sending uplink services in a multi-subband system. Background technique [0002] At present, there is a multi-subband communication system, the authorized frequency points of the multi-subband communication system are discretely distributed in the frequency band of 223.525MHz-231.65MHz, and the bandwidth of each frequency point is 25KHz. Wherein, the authorized frequency points are divided into sub-bands of the camping area, and the rest of the frequency points are divided into sub-bands of the working area, and the sub-bands of the camping area can be further divided into synchronous sub-bands and service sub-bands. The position of the uplink pilot time slot physical channel (UpPTS) on each service subband is allocated as the position of the uplink scheduling request (Scheduling Request, SR), and 8 preambles (Preamble) are generate...
