Abstract

This invention provides a method and a device for boosting up cover of UPA local areas, the method mainly includes: obtaining the power needed by the least UPAMAC-esPDU, the available power and the available SG sent by UE; transmitting a relationship among the power needed by the least PDU frame, the available power and the available SG according to the UE; selecting the related information transmitting strategy, especially when the available power resource of the UE is not enough, it allows the UE to transmit EDCH frame containing a least PDU datum. According to the method and device of the embodiment of the invention, it can enhance the UPA local areas covering and improve the user service at the area boundary.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method and device for enhancing UPA (Uplink Packet Access, Uplink Packet Access) cell coverage. Background technique [0002] HSUPA (High Speed ​​Uplink Packet Access, High Speed ​​Uplink Packet Access) is an important new feature in the third generation wireless communication (3G) WCDMA standard. For UPA users, the UE (User Equipment, user equipment) upload rate depends on the authorization value SG (Schedule Grant) given to the UE by the base station (NodeB) and the UE sends E-DPDCH (E-DCH DedicatedPhysical Data Channel, enhanced ( Uplink) dedicated physical data channel) data available power P avil E-DPDCH . When the UE is at the cell boundary, the transmission power of DPDCH (Dedicated Physical Data Channel, Dedicated Physical Data Channel) and DPCCH (Dedicated Physical Control Channel, Dedicated Physical Control Channel) of the UE is increased, and P avil ...
