Embodiment Construction

[0061] The present invention will be described below in conjunction with specific embodiments and accompanying drawings.

[0062] In the known technology, the mobile terminal sends signaling to the Node B through the E-UCCH in the E-PUCH, and the Node B calculates the modulation mode of the data transmitted in the E-PUCH according to the TFCI of the E-UCCH signaling, and adopts the calculated modulation mode The step of demodulating data, and the present invention adopts following method:

[0063] Add the modulation mode identifier indicating the modulation mode of the E-PUCH data part to the signaling, encode and modulate the signaling containing the modulation mode identifier of the E-PUCH data part, and send it to the Node B.

[0064] After receiving the signaling, the Node B directly demodulates the data according to the modulation mode indicated by the modulation mode identifier of the E-PUCH data part.

[0065] In order to realize the above method, the signaling needs t...

Abstract

The invention provides a TDCDMA system high-speed uplink packet access signaling transmitting method which includes the following steps: a mobile terminal transmits a signaling to a node B through E-UCCH in E-PUCH; the node B calculates a type of modulation of data transmitted in the E-PUCH according to TFCI of the E-UCCH signaling; the data is processed with the steps of modulation by adopting the calculated type of modulation, wherein, the steps further include: step one, a modulation type mark which indicates the type of modulation of the data part of the E-PUCH is arranged in the signaling, which includes the modulation type mark of the data part of the E-PUCH is transmitted to the node B after coded modulation; step two, the signaling is received by the node B, the modulation type mark of the data part of the E-PUCH is obtained from the signaling, the data transmitted in the E-PUCH is demodulated according to the type indicated by the modulation of the modulation type mark of the data part of the E-PUCH, thereby solving the problem that the signaling transmission mode easily causes errors in the data part in the prior art.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a high-speed uplink packet access signaling transmission method of a time division code division multiple access system. Background technique [0002] In the third-generation mobile communication system, in order to provide higher-speed uplink packet services and improve spectrum utilization efficiency, 3GPP (3rd Generation Partnership Project) introduced HSUPA (High Speed ​​Uplink Packet Access) into the specifications of WCDMA and TD-CDMA systems , high-speed uplink packet access) feature, that is, the uplink enhanced feature. [0003] The HSUPA system is also known as the uplink enhancement system. In the TD-CDMA system, the physical layer of the HSUPA system introduces the E-PUCH (E-DCH Physical Uplink Channel, E-DCH physical uplink channel) physical channel for transmitting E-DCH type CCTrCH (Coded Composite TransportChannel, Coded Composite Transport Channel). A sche...
