[0005] In the existing HSPA configuration, basically only one Enhanced Dedicated Channel Absolute Grant Channel (E-AGCH) is configured on the downlink time slot. Since there is no E-AGCH, the remaining code channel resources cannot be scheduled and used, such as the empty E-PUCH code channel of TS1 in the case of frame division

Embodiment Construction
[0043] The solution of the present invention is described in detail below through specific examples.
[0044] Embodiment 1 of the present invention is directed to the case of configuring one E-AGCH. The scheduling process of this embodiment is as follows Figure 4 shown, including the following steps:
[0045] Step 401: In the Nth frame currently scheduled, calculate the priorities of all UEs accessed in the cell.
[0046]Step 402: Determine whether the previous frame, that is, the N-1th frame, has a multi-frame grant allocated by the UE. If so, the E-PUCH resource of TS2 in the scheduled frame N+2 corresponding to the current frame has been occupied, and all Among the UEs that have not been scheduled, select the UE with the highest priority, allocate the E-PUCH resource of TS1 in the N+2th frame to the UE, set N=N+1, and return to step 401; otherwise, execute step 403.
[0047] Step 403: Among all unscheduled UEs in the currently scheduled Nth frame, select the UE with the...

Abstract
The invention provides an enhanced high-speed packet access scheduling method which comprises the following steps of: A, at an Nth frame of the current scheduling, judging whether more than one frame of E-PUCH (Enhanced-Physical Uplink Channel) resources are assigned by user equipment (UE) at the previous frame, namely an (N-1)th frame, if so, executing the step B, otherwise, executing the step C; B, selecting one of UE from all the unscheduled UE at the Nth frame, assigning the E-PUCH resources of the TS1 (Time Slot 1) at an (N+2)th frame to the UE, setting N to be equal to N+1, and returning to the step A; C, selecting one of UE from all the unscheduled UE at the Nth frame as the first UE, and calculating the number of code channels which are used for the first UE to actually send data; D, judging whether the number of the code channels which are used for the first UE to actually send data is less than 16, if so, scheduling the first UE by adopting the existing scheduling mode, assigning the E-PUCH resources of the first UE by using an E-AGCH (E-DCH Absolute Grant Channel), setting N to be equal to N+1, and returning to the step A, otherwise, executing the step E; and E, assigning more than one frame of the E-PUCH resources to the first UE, setting N to be equal to N+1, and returning to the step A. The invention also provides an enhanced high-speed packet access scheduling device.
Description
technical field [0001] The invention relates to the technical field of Time Division Synchronous Code Division Multiple Access (TD-SCDMA), in particular to an enhanced high-speed packet access (HSPA) scheduling method and device. Background technique [0002] The typical configuration of TD-SCDMA system HSPA network time slot switching point is 2:4, that is, two uplink time slots and four downlink time slots, resource pool configuration and control channel configuration are as follows: figure 1 As shown, one E-AGCH is configured. [0003] The downlink accompanying channel (ADPCH) is basically configured in the HSPA network, and the ADPCH adopts the method of frame division multiplexing. The situation of the code channel with 2 times the frame division is as follows figure 2 As shown, taking two frames as a cycle, the enhanced physical uplink channel (E-PUCH) with 4 code channels and the dedicated physical channel (DPCH) with 6 code channels are configured in the time slot...
