Abstract

This application provides a method and system for scheduling multi-cluster resources in an uplink shared channel. By counting users who need to allocate uplink resources, and generating a user list, calculating the carrier priority of each user in the user list on different carriers, determine The first carrier and the second carrier corresponding to each user allocate uplink resources for the user with the highest scheduling priority in the user list, and carry the resources to be transmitted by the user through the resource clusters of the first carrier and the second carrier. The first carrier with the highest level carries the user's to-be-transmitted resources. While ensuring the channel conditions of the resource clusters allocated to the user, the spectrum efficiency of the spectrum resources of each resource cluster is guaranteed, thereby improving the PUSCH resource utilization efficiency.

Description

technical field

[0001] The present application relates to the field of communication technologies, and in particular to a method and system for scheduling multi-cluster resources in an uplink shared channel. Background technique

[0002] LTE-A is an abbreviation of LTE-Advanced, and is a subsequent evolution of a Long Term Evolution (LTE) technology. In the LTE-A system, uplink channel estimation and signal demodulation are mainly accomplished by a demodulation reference signal (Demodulation Reference Signal, DMRS) of a physical uplink shared channel (Physical Uplink Share Channel, PUSCH). Specifically, after receiving the DMRS, the base station obtains the channel response on the PUSCH transmission bandwidth according to a certain channel estimation algorithm, and uses it for demodulating the PUSCH data on the corresponding bandwidth. Due to the single carrier characteristic of uplink, the longer the DMRS sequence, the more accurate the channel estimation and the better th...

Embodiment Construction

[0077] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0078] A new feature of the LTE-A system is to support uplink discontinuous transmission, which can obtain diversity gain and improve uplink throughput performance.

[0079] In PUSCH discontinuous resource allocation, the concept of multi-cluster transmission is introduced. Each cluster (that is, resource cluster) includes one or more continuous RBs, multiple resource clusters can be allocated to a UE at the same time, and the size and number of resource clusters can be flexibly scheduled.

[0080] The new standard (Rel-10) of the LTE-A system already supports the simultaneous allocation of two resource clusters on the same component How is the channel quality of each component carrier, multiple resourc...
