Problems solved by technology

[0005] Generally, when the existing power control technology configures the gain factor for the user equipment, the network notifies the user equipment of the gain factors of E-DPDCH and E-DPCCH through signaling (such as radio bearer control signaling). Different, the required QoS may also be different. Therefore, when performing power control, the uplink physical channels (including E-DPDCH and E-DPCCH) will be required to be configured with different gain factors, and the user equipment will be notified of the two enhanced The gain factor of the uplink dedicated physical channel occupies precious high-level signaling bandwidth, which undoubtedly increases the high-level signaling load of the network
[0006] In addition, since the gain factors of E-DPDCH and E-DPCCH are associated with the transmission format of the transmission channel, different transmission formats will require different gain factors. make the load heavier

Embodiment Construction

[0078] refer to figure 1 , which is a schematic diagram of the wireless interface protocol layer of the application of the enhanced uplink dedicated physical channel of the present invention.

[0079] According to the protocol specification of 3GPP, the wireless interface protocol layer of WCDMA is divided into three layers. Such as figure 1 As shown, the bottom layer is the physical layer, and the protocol layer above the physical layer (L1) is called the data link layer (L2) and the network layer (L3). In the UTRA FDD radio interface, the data link layer is divided into several sublayers. On the control plane, the data link layer (L2) consists of two sub-layers - medium access control (MAC) protocol and radio link control (RLC) protocol; on the user plane, in addition to MAC and RLC, there are two A protocol related to specific services: Packet Data Convergence Protocol (PDCP) and Broadcast / Multicast Control Protocol (BMC), the enhanced uplink dedicated physical channel o...

Abstract

This invention discloses one strengthening upper link special physical signal channel power control method, which comprises the following steps: the network side sending needed power control strengthened special physical data signal channel gains factors to user device and strengthened upper special physical control signal channel power added bias; user device determines the relative strengthened upper special physical data channel gains factors and the control signal channel gains factors; user device processing the relative power control according to the strengthened physical special signal channel factors and the said sure gain upper special physical control signal channel for power control. The invention also discloses one relative strengthened special physical signal channel control device.

Description

technical field [0001] The present invention relates to the power control technology in the wideband code division multiple access (WCDMA) mobile communication system, more specifically, the present invention relates to a kind of enhanced uplink dedicated physics Channel power control method and device. Background technique [0002] WCDMA is a standard technology of the third generation of mobile communication. Usually, the physical channels of WCDMA are divided into uplink and downlink. There are two dedicated physical channels and one public physical channel in the uplink, where the two dedicated physical channels are Dedicated Physical Data Channel (DPDCH: Dedicated Physical Data Channel) and Dedicated Physical Control Channel (DPCCH: Dedicated Physical Control Channel), public physical channel The channel is a Physical Random Access Channel (PRACH: Physical Random Access Channel). User data is transmitted on dedicated physical data channels; and control information on ...
