Abstract

The application provides a scheduling method and system of the multi-cluster resources in an uplink shared channel. The method comprises the steps of gathering the users needing to be distributed with the uplink resources, generating a user list, calculating the carrier priorities on different carriers of the users in the user list, determining the first carriers and the second carriers corresponding to the users, distributing the uplink resources to the user having the highest scheduling priority in the user list, and bearing the to-be-transmitted resources of the users via the resource clusters of the first carriers and the second carriers, wherein the first carriers having the highest priorities are used to bear the to-be-transmitted resources of the users as much as possible. According to the present invention, the frequency spectrum efficiency of the frequency spectrum resources of each resource cluster is guaranteed while guaranteeing the channel conditions distributed to the resource clusters of the users, thereby improving the resource utilization efficiency of a physical uplink shared channel (PUSCH).

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 (Long Term Evolvement, LTE) technology. In the LTE-A system, uplink channel estimation and signal demodulation are mainly completed 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 estimatio...

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...
