Problems solved by technology

Therefore, the power difference between the E-AGCH and the dedicated physical channel, that is, the power offset should change with the number of wireless connections and the quality of each wireless connection, and it is difficult for the base station to adjust itself
In this way, the demodulation accuracy of E-AGCH cannot be guaranteed for all users, or in order to ensure the demodulation accuracy of users, the base station transmits relatively large E-GACH power in a conservative manner, resulting in unnecessary power consumption
[0007] To sum up, in the process of implementing the present invention, the inventors found that in the prior art at least the configured E-AGCH transmission power is often relatively large, resulting in unnecessary power consumption

Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention more clearly, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] An embodiment of the present invention provides a method for determining E-AGCH transmission power.

[0028] In the embodiment of the present invention, the transmit power of the E-AGCH is determined according to the transmit power of the common pilot channel CPICH, the channel quality indicator and the power offset.

[0029] Normally, when HSUPA is used for uplink, HSDPA high-speed downlink packet access is used for downlink, and the serving cells of HSUPA and HSDPA are the same. In this case, the user equipment (User Equipment, UE) will periodically send a channel quality indicator (ChannelQuality Indicator, CQI) to the Node B, which indicates the downlink channel quality of the serving cell, so the transmission power of the ...

Abstract

The embodiment of the invention provides a determination method for improving an enhanced E-AGCH emitting power and device thereof, which mainly comprises that: a power bias is acquired, the E-AGCH emitting power can be determined according to a common pilot channel CPICH emitting power and a channel quality indication CQI as well as the power bias, thereby the E-AGCH emitting power can be reasonably configured so as to adapt the change of a wireless channel.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a technology for determining the transmit power of an enhanced absolute grant channel. Background technique [0002] HSUPA (High Speed ​​Downlink Packet Access, High Speed ​​Uplink Packet Access) is a wireless side uplink enhancement technology introduced in the R6 version of the 3GPP protocol system. It uses fast retransmission, hybrid ARQ (Automatic Repeat Request, automatic repeat request) and base station-based distributed control method to complete the high-speed uplink data transmission function. Five new physical channels, E-DPDCH (Enhanced Dedicated Physical Channel), E-DPCCH (Enhanced Dedicated Physical Control Channel), E-AGCH (Enhanced Absolute Grant Channel), E-RGCH (Enhanced Relative Authorized channel), E-HICH and two new MAC entities MAC-e and MAC-es, and move the packet scheduling function from RNC to NodeB, realizing fast packet scheduling based on NodeB, and...
