Resource Scheduling Method and Device in Coordinated Multipoint Transmission Scenario

Abstract

The invention discloses a method and device for resource scheduling in a coordinated multi-point transmission scenario, which are used to solve the problem of how to perform resource scheduling for CoMP UEs when scheduling collisions occur in the prior art. The method of the present invention includes: the serving base station of the CoMP UE determines the service to be transmitted of the CoMP UE, and the time-frequency resource corresponding to the service to be transmitted; the serving base station determines the time-frequency resource according to the set scheduling The priority is to schedule the service to be transmitted of the CoMP UE, where the scheduling priority of the service requiring high delay of the CoMP UE is higher than the scheduling priority of the service requiring low delay of the CoMP UE. In the present invention, since the serving base station schedules the service to be transmitted of the CoMP UE on the determined time-frequency resource according to the set scheduling priority, the smooth execution of the CoMP UE scheduled transmission is guaranteed when a scheduling collision occurs.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a resource scheduling method and device in a scenario where a central coordination node (central coordination node, CCN) and a serving base station jointly schedule the terminal. Background technique [0002] At present, the network architecture of the Evolved Universal Terrestrial Radio Access Network (Evolved Universal Terrestrial RadioAccess Network, E-UTRAN) can be found in figure 1 As shown, the E-UTRAN is composed of eNB (evolved base station), and the eNB completes the access network function and communicates with user equipment (UE, User Equipment) through an air interface. There is both a control plane connection and a user plane connection between the UE and the eNB. For each UE attached to the network, there is a Mobility Management Entity (MME) to provide services for it. The MME is connected to the eNB through the S1-MME interface, and the S1-MM...

AI Technical Summary

Problems solved by technology

However, for CoMP UEs, in the same time-frequency resource of the same subframe, there may be traditional scheduling of the CoMP UE by the serving base station (that is, the serving base station of the CoMP UE follows the traditional scheduling method defined in the LTE R8 standard (see TS36 .321 protocol) to schedule the transmission of the corresponding bearer by itself), and there is also cooperative scheduling by CCN, and scheduling collisions occur

[0016] To sum up, there is no solution for how to perform resource scheduling for CoMP UEs when scheduling collisions occur.
