Embodiment Construction

[0031] In order to achieve the purpose of the present invention, the applicant utilizes the characteristics of different round-trip times when different physical resources (time slots or subframe positions) bear the services specified by the sending side in the TDD system, and on the basis of fairness, the applicant will Users with higher latency requirements correspond to physical resources with shorter round-trip time, and use the short round-trip time to execute user services as much as possible. The solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] In each embodiment of the present invention, scheduling is performed in units of the smallest physical resource, which is called the smallest scheduling resource block (Resource Block, RB). The smallest scheduling unit of different systems may be different, and the composition and size of RBs are also different. . For example, in ...

Abstract

The invention discloses a method for dispatching resources, which comprises the following steps: distributing the priority level for to-be executed business, orderly selecting the resource which bears the business data from the sub-frames in bearer service data in the cycle according to the priority level with the order of from high to low. The method reduces the reciprocating time of the business which has high requirements to resist the time delay as much as possible and greatly improves the executing success rate of the business. The invention discloses a device and a communication system for dispatching resources.

Description

technical field [0001] The present invention relates to data transmission technology in the communication field, in particular to a method and device for resource scheduling and a communication system. Background technique [0002] During the data transmission process of a time division duplex (TDD) system and a frequency division duplex (FDD) system, the medium access control (MAC) layer on the receiving side generally needs to If there are many data packets to be processed, a certain amount of queuing time is required. These queuing time and processing time can be called MAC layer delay. In the long term evolution standard (Long term evaluation, LTE) of 3GPP The MAC layer delay defined in is about 2ms-3ms. Since the data transmission process of the TDD system is a discontinuous process, the feedback information returned by the receiving side must be transmitted using the corresponding time slot, so it requires a longer round trip time (Round Trip Time, RTT) than the FDD s...
