Problems solved by technology

[0009] Although the UE scheduling problem can be solved by fixed delay in FDD mode, in TDD mode, since only one-way uplink or downlink communication can be performed in each TTI, the uplink communication of UE is restricted. Therefore, in TDD It is difficult to solve the problem of UE scheduling by using a fixed delay relationship in the mode
[0010] At present, there is no clear way to implement UE scheduling in TDD mode of LTE

Embodiment 1

[0080] In the methods described in Embodiment 1 and Embodiment 2, the TTI resource is indicated by the correspondence between each bit in the TTI resource indication field and the TTI. It is also possible to directly use the TTI number as the TTI resource indication field, as shown in Table 2.

[0083] In the following, in conjunction with Embodiment 3, the method for scheduling UE using the TTI number as the TTI resource indicator field will be specifically described, as Figure 4 It is a flowchart of Example 3.

[0084] In step 401, the scheduler selects a scheduled UE and allocates carrier resources and TTI resources.

[0085] In step 402, the base station will generate the same number of scheduling instructions according to the number of TTIs allocated by the scheduler. Among them, each scheduling instruction w...

Abstract

The invention discloses a method for scheduling UE, which comprises the steps that: a TTI resource indication field is added in a scheduling instruction; the scheduling instruction containing the indication information about carrier resources is generated after carrier resources and TTI resources are allocated; the TTI resource indication field is set according to the allocated TTI resources and the scheduling instruction is sent to the scheduled UE. The adoption of the method provided by the invention can add the indication information about TTI resources in the scheduling instruction so as to cause the scheduled UE to be informed of TTI resources allocated at the network side by the scheduling instruction, thereby avoiding the fixed delay relation from being adopted to schedule a UE in a TDD mode, thus not only realizing the scheduling of the UE but also providing simplicity and convenience. The invention also discloses a device for scheduling the UE.

Description

Technical field [0001] The present invention relates to the technical field of user equipment (UE) mobility management in a time division duplex (TDD) mobile communication system, and in particular to a method and device for scheduling UE. Background technique [0002] Long Term Evolution (LTE) is an evolution technology being studied by the Third Generation Partnership Project (3GPP) organization. The working mode of LTE can be divided into two basic modes: Frequency Division Duplex (FDD) and Time Division Duplex (TDD). In the FDD mode, different frequency bands are occupied for uplink and downlink communication in the frequency domain. In the time domain, each time slot can perform uplink and downlink bidirectional data transmission. In the TDD mode, uplink and downlink communications in the frequency domain occupy the same frequency band. In the time domain, each time slot can only perform uplink or downlink unidirectional data transmission. [0003] In LTE, the resources used...
