Embodiment Construction

[0053] In order to solve the problems of slow SPS search resource speed and low RB resource utilization in the prior art, the present invention provides a method and device for resource allocation under semi-persistent scheduling. The method is: search and record the entire The size of holes in the system bandwidth and the corresponding number of holes; when it is determined that the first user needs to establish an SPS service, calculate the number of RBs required by the SPS service, based on the size of the holes in the entire system bandwidth and the corresponding number of holes. The user allocates holes, and updates the hole size and the corresponding number of holes in the entire system bandwidth based on the allocation results; when it is determined that the second user releases the SPS service, the RB occupied by the second user is released to form a new hole, and based on the release As a result, the hole size and the corresponding number of holes in the entire system ...

Abstract

The invention relates to the field of communication, in particular to a semi-static scheduling resource distributing method and device used for achieving rapid semi-static scheduling resource distribution and increasing the dynamic service RB resource use rate. The method includes the steps of seeking and recording the sizes of holes and the numbers of the corresponding holes in a whole system bandwidth; when it is determined that a first user needs to build an SPS service, calculating the number of RB resources required by the SPS service, distributing the RB resources for the first user according to the sizes of the holes and the numbers of the corresponding holes in the whole system bandwidth, and updating the sizes of the holes and the numbers of the corresponding holes in the whole system bandwidth based on the distribution result; when it is determined that a second user releases the SPS service, releasing the RB resources occupied by the second user, forming new holes, and updating the sizes of the holes and the numbers of the corresponding holes in the whole system bandwidth based on the releasing result. The semi-static scheduling resource distributing speed is greatly increased.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for resource allocation under semi-persistent scheduling. Background technique [0002] Voice over LTE (VoLTE) is an IMS-based voice technology, which can provide higher call quality and solve the problems of data intercommunication and roaming. This technology can not only bring carrier-class voice quality to users, but also realize the integration of voice, video, data, emergency call and other services under the framework of IP Multimedia Subsystem (IMS), so it has become the mainstream in the world The long term evolution (Long Term Evolution, LTE) voice solution. [0003] In addition, VoLTE is also an IP data transmission technology. It does not need 2G / 3G network, and carries all services on the 4G network, which can realize the unification of data and voice services under the same network. In other words, the 4G network can not only provide high-spee...
