Uplink signaling transmission method and uplink resource allocation method

Abstract

The invention discloses an uplink signaling transmission method and an uplink resource allocation method, wherein, the transmission method comprises the following steps: a. a network reserves code channel resources of a shared feedback channel (HS-SICH) using a high-speed downlink data access technology for UE which supports an MIMO function according to a double-flow feedback mode and informs the UE; and b. when the UE adopts single-flow transmission, the UE transmits a signaling for assisting a base station with downlink scheduling to the base station by utilizing code channel resources of the HS-SICH according to a single-flow mode, and transmits an uplink signaling for assisting the base station with uplink scheduling or interference control to the base station by the unused code channel resources in the reserved code channel resources. The invention can reduce access delay when the base station carries out uplink resource allocation and avoid waste of the code channel resources.

Description

technical field [0001] The present invention relates to a control signaling transmission technology in a mobile communication system, in particular to an uplink signaling transmission method and an uplink resource allocation method realized by the method. Background technique [0002] In the existing mobile communication system, the base station usually performs uplink scheduling according to the uplink signaling transmitted by the UE, that is, the Buffer data size, service priority and other information carried in the UE Scheduling Request Information (SI). For example, in the TD-SCDMA system, the uplink scheduling request information is sent to the base station ( NodeB), the NodeB decides whether to allocate uplink resources to the user equipment (UE) according to the uplink scheduling request information. Since RACH and E-RUCCH are common channels, resource requests through these channels may conflict or collide. After the conflict, RACH access needs to be performed agai...

AI Technical Summary

Problems solved by technology

Since RACH and E-RUCCH are common channels, resource requests through these channels may conflict or collide. After the conflict, RACH access needs to be performed again, resulting in a large access delay.

In addition, this method requires the system to reserve E-RUCCH and RACH resources, so there is a problem of wasting code channel resources

[0003] It can be seen that the existing method of transmitting the above-mentioned uplink control signaling to the base station will cause a long access delay when the base station allocates uplink resources and waste code channel resources.
