Problems solved by technology

[0013] The purpose of the present invention is to provide a method for sending an enhanced uplink control channel, to overcome the problem in the prior art that only the number determined by the high layer can be sent when the number actually required by the E-UCCH is less than the number determined by the high layer. The disadvantage that the quality of the generated E-UCCH cannot be guaranteed

Embodiment Construction

[0036] The core of the present invention is to provide a method for sending an enhanced uplink control channel, which maps the E-UCCH to the E-PUCCH for sending. During specific implementation, the E-PUCCH channel is introduced, and the E-UCCH that has undergone channel coding, rate matching, bit scrambling and interleaving is mapped to the data symbol part of the E-PUCCH for transmission. A CRC check code can also be added to ensure that the receiving end only receives correct E-UCCH messages.

[0037] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0038] As mentioned earlier, when the number of E-PUCHs allocated to E-PUCHs in a TTI is less than the number of E-UCCHs actually required to be sent, it will be sent according to the number of allocations. In this way, the number of E-UCCHs sent R...

Abstract

The present invention discloses a transmitting method for enhancing the ascending control communication channel, which is used in the high-speed ascending grouping assessing technique, an enhancing physical upgoing control channel E-PUCCH is taken into the method, and the method comprises the steps of: treating the enhancing upgoing control channel E-PUCCH; and mapping the treated E-UCCH to the E-PUCCH and transmitting. Wherein the processing procedure to the E-UCCH includes channel coding, speed adapting, bit scrambling and interweaving, otherwise, the redundant cyclic checking code can be added before the processing procedure. Using the invention as the incoming E-PUCCH partly transmits the data symbol which is mapped to the E-PUCCH after the process of channel coding, speed adapting, bit scrambling and weaving, the quality of the E-UCCH is guaranteed. Meanwhile, the receiving end can judge whether the E-UCCH is correctly received with adding the CRC checking code.

Description

technical field [0001] The present invention relates to a high speed uplink packet access (High Speed ​​Uplink Packet Access, HSUPA) technology, in particular to a method for sending an enhanced uplink control channel. Background technique [0002] High Speed ​​Uplink Packet Access (HSUPA) is a technology developed for high-speed transmission of uplink data based on the third-generation mobile communication technology. It can provide complete multimedia, video streams and other information required by IMT2000. Services based on Internet Protocol (Internet Protocol, IP). [0003] In order to support HSUPA technology, some transmission channels and control channels have been added. [0004] The newly added transport channels include: Enhanced Dedicated Transport Channel (E-DCH) and Enhanced Uplink Control Channel (E-UCCH). [0005] The newly added physical channels include: Enhanced Uplink Physical Channel (E-PUCH) and Absolute Acknowledgment Channel (E-AGCH). [0006] Amon...
