Embodiment Construction

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] 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:

[0033] Step 110, the radio network controller sends signaling to the base station, the signaling carries the maximum transmission power MaxHspdschPower that can be used by the protocol data unit of the media access control entity of the high-speed downlink shared channel in one transmission time interval, or carries Maximum transmit power MaxHsscchPower available for MaxHspdschPower and HS-SCCH;

[0034] The above signaling may be a common transport channel establishment request message or a common transport channel reconfiguration request message. The radio network controller can calculate the maximum transmit powe...

Abstract

The invention relates to a method for controlling power of a physics channel mapped by a high speed downstream sharing channel, comprising: (a) a wireless network controller informs a base station via signaling that a protocol data unit of a media accession controlling entity of the high speed downstream sharing channel can use a maximum transmitting power MaxHspdschPower or a maximum transmitting power which can be used by the MaxHspdschPower and a sharing controlling channel HS-SCCH for the high speed downstream sharing channel in a transmission time interval; (b) when the wireless network controller sends data which needs to be transmitted to a user device to the base station, an emission power level used for transmitting the data is carried in data frame of the high speed downstream sharing channel; (c) when sending the data to the user device, the base station determines an actually used emission power of HS-PDSCH and HS-SCCH according to the MaxHspdschPower, the emission power level and an emission power of a public pilot channel which are gained in advance, and uses the actually used emission power of HS-PDSCH and HS-SCCH to send the signaling and / or data.

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...
