Abstract

The invention discloses a method and a device for uplink semi-persistent scheduling resource allocation. The method includes: acquiring an available resource range of a current subframe, judging whether the current subframe has SPS (semi-persistent scheduling) users needing to be activated or not, and if yes, determining a start resource block RBstart of resources needed by the current subframe for activating SPS according to the principle of allocating from two ends of the available resource range of SPS resources of a subframe n and a subframe n+1, wherein t refers to time interval of SPS new transmission and SPS non-adaptive retransmission; scheduling uplink grant for activating SPS based on the start resource block RBstart, and updating the available resource range of the current subframe; and judging whether all SPS users, needing to be activated, of the current subframe are scheduled or not, and if not, repeating the operations based on the updated available resource range of the current subframe. Using the method and the device can solve the problem of uplink SPS resource contention of multiple UE (user equipment) caused by Gap and improve transmission performance of uplink SPS services.

Description

Technical field [0001] The present invention relates to the field of communication technology, and in particular to an uplink semi-persistent resource scheduling allocation method and device. Background technique [0002] The LTE (Long Term Evolution, Long Term Evolution) system uses a shared resource method to schedule user data. This scheduling method can utilize wireless communication resources to a great extent, but at the same time, this method requires a relatively large control information overhead. In the LTE system, all voice services in the circuit domain are cancelled and replaced by VoIP services in the data domain. The number of voice users is often relatively large. LTE uses a shared resource allocation and scheduling method. Each transmission requires related Control information, due to the excessive overhead of control information, limits the number of users that the LTE system can support at the same time. Therefore, for real-time services with a relatively fixe...
