Uplink resource allocation method and uplink resource allocation device

Abstract

The invention discloses an uplink resource allocation method, which includes scanning time slots in a resource pool to obtain free available spreading factors SF and channelization codes in all the time slots, extracting time slots with identical SF and identical power gains and corresponding time slot-code channel combinations in the free available SF and the channelization codes to form a middle resource block, analyzing spreading factors in the middle resource block to form a resource block, and allocating resources for users according to transmission capacity of a single time slot of the resource block and user resource requirements. An uplink resource allocation device is further disclosed. By means of the uplink resource allocation method and the uplink resource allocation device, resource waste in allocation can be reduced, the number of users a system can accommodate is increased, and resource use ratio of the system is improved.

Description

technical field [0001] The present invention relates to mobile communication resource allocation technology, in particular to an uplink resource allocation method and an uplink resource allocation device. Background technique [0002] As a further evolution of the Time Division-Synchronous Code Division Multiple Access (TD-SCDMA, Time Division-Synchronous Code Division Multiple Access) system, the Third Generation Partnership Project (3GPP, 3 rd Generation Partnership Project) introduces Time Division Duplex (TDD, Time Division Duplex) High Speed ​​Packet Access Plus (HSPA+, High Speed ​​Package Access Plus) technology in R8. From the evolution of High Speed ​​Uplink Packet Access (HSUPA, High Speed ​​Uplink Packet Access) of TD-SCDMA system to HSPA+, the scheduling algorithm, as the core algorithm of system wireless resource management and resource allocation, has always been the focus of research. The base station reasonably allocates cell resources and user transmission...

Problems solved by technology

[0015] It can be seen from the above that the existing resource allocation methods of time-division allocation or code-division allocation are relatively single, which is likely to cause waste of resource allocation and cannot flexibly match and adapt to service resource requirements. For example, for time-division allocation methods, due to The base station allocates all the code channel resources in the calculated time slot to the user. For the user transmitting the SPS service, the user may only need some code channel resources in the time slot to meet the SPS service requirements (user The amount of cache), like this, just wasted other code channel resources in this time slot, thereby also limited the maximum number of SPS users that the TD-SCDMA system can accommodate; Although the code division allocation method has a smaller Resource allocation granularity, but similar problems exist

That is to say, the existing uplink resource allocation method, due to the single resource allocation method, leads to the waste of allocated resources, reduces the number of users that the system can accommodate, makes the system resource utilization rate low, and cannot match and adapt to multi-service resources. requirements, especially for the uplink resource allocation of small data volume services
