Embodiment Construction

[0028] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0029] figure 2 A flow chart showing an uplink scheduling method according to an embodiment of the present invention includes the following steps:

[0030] Step S10, E-UTRAN decides the scheme of allocating new semi-persistent resources;

[0031] Step S20, E-UTRAN sends the scheme through PDCCH;

[0032] Step S30, the user equipment receives the solution on the PDCCH and analyzes and learns new semi-persistent resources;

[0033] Step S40, the E-UTRAN and the user equipment use the new semi-persistent resource and release the original semi-persistent resource.

[0034] It can be seen that, because the uplink scheduling method adopts semi-persistent resource reconfiguration, it overcomes the problem of resource waste and low efficiency caused by frequent use of dynamic scheduling to cover semi-persistent scheduling, and thus has hig...

Abstract

The invention provides an uplink dispatching method for a wireless communication system. The uplink dispatching method comprises the following steps that: an E-UTRAN decides a proposal for allocating a new semi-persistent resource; the E-UTRAN sends the proposal through a physical downlink control channel; a user device receives the proposal in the physical downlink control channel PDCCH and acquires the new semi-persistent resource through analysis; and the E-UTRAN and the user device use the new semi-persistent resource and release the prior semi-persistent resource. The method has the advantages of high wireless resource utilization rate, L1/L2 control channel expense reduction, high reliability, and the like.

Description

technical field [0001] The present invention relates to the communication field, in particular to an uplink scheduling method for a wireless communication system. Background technique [0002] The structure of the radio interface protocol uplink layer 2 of the "Evolved Universal Terrestrial Radio Access Network (E-UTRAN: Evolved Universal Terrestrial Radio Access Network)" of the third-generation mobile communication long-term evolution (LTE: Long Term Evolution) system is as follows: figure 1 As shown, there is a scheduling / priority handling (Scheduling / Priority handling) functional entity at the media access control (MAC, Media Access Control) protocol layer, wherein the scheduling function supports dynamic scheduling (Dynamic scheduling) and semi-persistent scheduling (Semi-persistent Scheduling) (or semi-static scheduling). [0003] The priority processing function supports priority processing between different logical channels of a user equipment (UE, User Equipment), ...
