Embodiment Construction

[0023] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0024] The present invention proposes a method for HS-SCCH code channel scheduling selection, which is used for the selection of MAC-hs module scheduling HS-SCCH code channel in WCDMA system NodeB, refer to figure 1 , is the HS-SCCH code channel scheduling selection flow chart of the present invention, and concrete steps are as follows:

[0025] Step S101, assign weights to all users in the current scheduling candidate queue, and the weights of high-priority users are greater than the weights of low-priority users, denoted as Wue.

[0026] If the number of users in the current scheduling candidate queue is N, the weights of each user can be set to N, N-1, . . . 1 according to the scheduling priority from high to low.

[0027] The aforementioned scheduling candidate queue is the user queue waiting for scheduling. This queue is the queue that t...

Abstract

The invention discloses a method for dispatching and choosing of an HS-SCCH code track of a system WCDMA, used for choosing of dispatching the HS-SCCH code track of a MAC-hs module in a node B of the system WCDMA, and the method includes: step one, a weight is endowed to all users of a current dispatching candidate queue, wherein, a weight of users of high priority is higher than a weight of users of low priority; step 2, all users of the candidate queue are dispatched in an order of from top to bottom according to a priority level of the users and the HS-SCCH code track is chosen for these users; step three, whether the dispatching of all users of the current dispatching candidate queue is finished or whether dispatching resources are used up are judged, if yes, the dispatching can be ended and gets into the next dispatching cycle; if no, step two is carried out circularly. An adoption of the invention can assure a simple and highly efficient dispatching and choosing of the HS-SCCH code track.

Description

technical field [0001] The invention relates to a method for scheduling and selecting HS-SCCH code channels in a WCDMA system, in particular to a method for scheduling and selecting HS-SCCH code channels when used for MAC-hs scheduling of NodeB in the WCDMA system. Background technique [0002] In the MAC-hs (High Speed ​​Media Access Control Module) scheduling of the WCDMA system, each scheduling period (TTI) needs to determine the scheduling priority of the user according to the scheduling priority of the user, select resources for user scheduling according to the available resources of the system, and determine the scheduling Wireless parameters. [0003] The HS-SCCH (High Speed ​​Shared Control Code Channel) is an important system resource, carrying control information of the user's downlink HSDPA data channel. The HS-SCCH code channel in the cell is a shared channel, which can be used by multiple users in time-sharing. At the same time, each user has its own HS-SCCH co...
