A method and device for uplink semi-persistent scheduling resource allocation

Abstract

Disclosed are a method and an apparatus for allocating an uplink semi-persistent scheduling resource. The method comprises: obtaining an available resource range of a current sub-frame, and when determining that a user required to activate SPS exists in the current sub-frame, with a principle that SPS resources of a sub-frame n and a sub-frame (n+t) start to be separately allocated from two ends of the available resource range, determining a start resource block RBstart of a resource required for the current sub-frame to activate SPS of the user; and based on the start resource block RBstart, scheduling an uplink to authorize activation of SPS, and updating the available resource range of the current sub-frame. According to the solution provided in the present invention, a resource newly transmitted through SPS and a resource retransmitted non-adaptively through SPS are distributed at two ends of an available resource, so as to avoid the problem of a conflict among uplink SPS resources of multiple UEs caused by a measurement Gap and improve transmission performance of an uplink SPS service.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for scheduling and allocating uplink semi-static resources. Background technique [0002] The LTE (Long Term Evolution, Long Term Evolution) system uses shared resources to schedule user data. This scheduling method can greatly utilize wireless communication resources, but at the same time, this method requires a large control information overhead. In the LTE system, all voice services in the circuit domain are canceled and replaced by VoIP services in the data domain. However, the number of voice users is often relatively large, and LTE uses a shared resource allocation and scheduling method. Each transmission requires related For control information, since the overhead of the control information is too large, the number of users that the LTE system can support simultaneously is limited. Therefore, LTE introduces Semi-Persistent Scheduling (Se...
