AI Technical Summary

Problems solved by technology

Due to the existence of Chip Offset, Node B also needs a certain amount of time to process UEs. If the scheduling period is relatively small, such as 10ms, and the number of UEs to be scheduled is relatively large, it may not be possible to process all UEs within one scheduling period. Delayed delivery of scheduling results
As mentioned above, the result of the delayed transmission of the scheduling result is that the UE cannot update the SG value and select the E-TFCI according to the normal timing relationship, so that the normal scheduling cannot be realized.

Embodiment 1

[0056] image 3 It is a flowchart of uplink scheduling controlled by a base station according to Embodiment 1 of the present invention. Such as image 3 As shown, in this embodiment, the uplink scheduling controlled by the base station mainly includes the following steps:

[0057] Step 301: Node B divides all UEs in the cell into two groups according to the Chip Offset randomly allocated to UEs by the system.

[0058] Since the value range of the Chip Offset is 0 to 149, preferably, UEs are grouped according to the principle of equal distribution, for example, UEs whose Chip Offset values ​​are in the range of [0, 74] are used as UEs in the first group, and UEs whose Chip Offset values ​​are within the range of [75, 149] are the UEs in the second group.

[0059] It should be understood that the value of the Chip Offset that is an odd number may also be used as the first group, and the value of the Chip Offset that is an even number may be used as the second group.

Abstract

This invention discloses an uplink dispatch method for base station control including: dividing UE in an area into N groups based on the code chip offset of the UE to dispatch UE of N groups in N dispatch periods, in which, although the original dispatch period is maintained, yet the dispatched UE numbers in each period can be reduced so as to reduce the problem that Node B is unable to issue the dispatch result in the time stated in the protocol since it has not enough time to process UE and secure that UE can update E-TFCI occording to normal time sequences to realize normal dispatch.

Description

technical field [0001] The present invention relates to High Speed ​​Uplink Packet Access (HSUPA, High Speed ​​Uplink PacketAccess) technology, in particular to an uplink scheduling method controlled by a base station. Background technique [0002] HSUPA technology is a new technology introduced by 3GPP in the Rel'6 protocol to improve the uplink transmission rate. It adopts uplink fast scheduling controlled by Node B, hybrid automatic repeat request (HARQ, Hybrid Automatic Repeat Request), and 2ms short frame technology , so that the user's uplink throughput rate has been greatly improved, theoretically supporting a peak rate of up to 5.76Mbps, and the system's uplink capacity has also been greatly improved, so that multimedia services and packet data transmission can be better developed. [0003] Scheduling data services of user equipment (UE, User Equipment) has always been an important research topic of 3GPP, and uplink scheduling technology is one of the basic problems....
