Embodiment 1

[0070] In this embodiment, the users can be sorted according to their scheduling priority and the user with the highest priority can be determined; the HS-SCCH resources available on the current air interface with different index numbers can be assigned to the user with the highest scheduling priority; and in each Under the index number, pre-allocate the available HS-SCCH resources of the current air interface for each user in turn according to the user's scheduling priority, and obtain the pre-allocation scheme under each index number; then according to the QoS performance requirements of the HSDPA system, HS-SCCH resource utilization Determine the pre-allocation scheme for implementing allocation, and allocate the shared control channel resources according to the pre-allocation scheme.

[0071] Further, the available HS-SCCH resources of the current air interface can be sorted according to the size of the index number; under each index number, the HS-SCCH resources available ...

Embodiment 2

[0093] This embodiment is based on the established HS-SCCH in the HSDPA system as a clue, the system allocates the HS-SCCH mechanism, first sorts the index number of the available HS-SCCH resource of the current air interface, and determines the current air interface available HS with the lowest index number -SCCH resource; then assign the HS-SCCH resource available to the current air interface with the lowest index number to users with different scheduling priorities; in each scheduling priority, according to the index number of the available HS-SCCH resource on the current air interface, assign each The available HS-SCCH resources of the current air interface are pre-allocated to users with different scheduling priorities, and the pre-allocation scheme under each scheduling priority is obtained; finally, the pre-allocation is determined according to the QoS performance requirements of the HSDPA system and the utilization rate of HS-SCCH resources. scheme, and allocate shared ...

Embodiment 3

[0108] This embodiment is an HS-SCCH priority allocation method with a low index number. During implementation, the HS-SCCH resources available on the current air interface can be allocated sequentially according to the user's scheduling priority; Available HS-SCCH resources for the current air interface allocated in sequence.

[0109] That is, during scheduling, strictly according to the order of user priorities, select the HS-SCCH with the lowest number and not occupied by high-priority users in the respective HS-SCCH candidate resource sets for use. In the implementation, choosing the lowest index number to implement can make the implementation more convenient and occupy less processor resources.

[0110] For example, in the current HSDPA system, 4 pairs of shared channels with HS-SCCH numbers 0 to 3 have been established, and there are 5 users online, and their priority order is user 0>1>2>3>4, assuming that each priority user The standby HS-SCCH resource set such as Fi...

Abstract

The invention discloses a method, a system and a base station for distributing the shared control channel resources of the high-speed downlink shared channel of a high-speed downlink package access system; the invention comprises that Node B acquires the user uplink time slot and the processing capacity of a physical channel and the Node B distributes the shared control channel resources for users according to the uplink capacity, the present idle available shared channel resources and the service quality and performance requests of the high-speed downlink package access system. The invention avoids the phenomenon that when the shared information which is corresponding to the shard control channel resources distributed to users indicates that the channel resources exceeds the uplink processing capacity of the user, the user could not feed back and confirm or does not confirm the indication information of the channel quality; in this way, the high-speed downlink package access system could implement normal adaptive modulation and coding (AMC) and the hybrid automatic repeat request (HARQ) processing. With the invention, the shared control channel resources of the high-speed downlink package access system could be fully utilized with high efficiency.

Description

technical field [0001] The invention relates to high-speed downlink packet access system technology, in particular to a method, system and base station for allocating shared control channel resources of high-speed downlink shared channels in the high-speed downlink packet access system. Background technique [0002] In the HSDPA (High Speed ​​Downlink Packet Access, high-speed downlink packet access, high-speed downlink packet access) system to allocate resources for users, the user is required to establish HS-SICH (Shared Information Channel for HS-DSCH, HS-DSCH sharing in each uplink time slot) Information indication channel, where HS-DSCH is the total number of physical channels such as High Speed ​​Downlink Shared Channel (High Speed ​​Downlink Shared Channel), UL DPCH (UpLink Dedicated Physical Channel, uplink dedicated physical channel) and the total time occupied by these uplink physical channels The number of slots does not exceed the user's uplink processing capabil...
