Embodiment Construction

[0035] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0036] Such as figure 1 As shown, this embodiment strengthens the physical channel power control method related to the high-speed shared channel in the public state of the connected mode, including the following steps:

[0037] Step 110, the radio network controller sends signaling to the base station, the signaling carries the maximum transmit power (MaxHsPower) available for the physical channel related to the high-speed downlink shared channel, that is, the two physical channels HS-PDSCH and HS-SCCH The sum of the maximum transmit power;

[0038] The above signaling may be a common transport channel establishment request message or a common transport channel reconfiguration request message. The maximum transmission power is a relative value, which is the deviation between the transmission power (minimum transmission power) requir...

Abstract

The present invention discloses a method for controlling the power of the physical channel mapped by the high-speed descending sharing channel, and the method comprises the following steps: (a) informing the maximum emitting power of the physical channel mapped by the high-speed descending sharing channel by the wireless network controller, and the maximum emitting power is the deviation value between the emitting power which is needed when the subscriber facility correctly receives the data with the high-speed descending sharing channel at the edge of the subdistrict and the emitting power of the common pilot channel; (b) when the wireless network controller transmits the data which needs to be transmitted to the subscriber facility to the base station, carrying the emitting power level used in transmitting the data in the data frame of the high-speed descending sharing channel; and (c) when the base station transmits data to the subscriber facility, confirming the emitting power which is actually used by the physical channel according to the pre-obtained maximum emitting power, the emitting power level and the emitting power of the common pilot channel, and transmitting signaling and / or data to the subscriber terminal.

Description

technical field [0001] The invention relates to a method for controlling the power of the physical channel mapped by the high-speed downlink shared channel in the public state of the enhanced connection mode in a mobile communication system. Background technique [0002] In order to improve the user's high data traffic and system throughput, 3GPP's R5 standard protocol introduces a high-speed packet shared transmission channel (High Speed ​​Downlink Shared Channel: HS-DSCH), the physical channel mapped by the channel adopts time division and code division way, and the channel uses Hybrid Automatic Repeat (HARQ) and Adaptive Modulation Coding (AMC) technology, making the peak rate up to 10.8Mbps to 30Mbps. Its ultimate purpose is to increase the capacity of the system and reduce transmission delay by providing access to high-speed packet services to improve users' requirements for quality of service (QoS). [0003] The current protocol uses the supplementary common control p...
