Embodiment Construction

[0090] The core of the present invention is to provide a method and system for message multiplexing on E-HICH. During specific implementation, the TPC and SS messages of the E-PUCH in the non-scheduled transmission are multiplexed on the idle bits of the E-HICH channel. The present invention also provides a method and system for sending messages on E-HICH, in which the ACK / NACKs of users with the same incoming wave direction or similar signal quality are multiplexed on the E-HICH channel, and the method of message multiplexing on E-HICH is applied The method and system process and send the signal.

[0091] 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.

[0092] The method and system for message multiplexing on the E-HICH are introduced below.

Abstract

The present invention discloses a method of the message multiplexing on the acknowledgement indicator channel (E-HICH). After multiplexing the converted response messages of different subscribers, the E-HICH channel generates idle bits, in which a power controlling and synchronizing message is filled and then sent out in the form of spread spectrum. The present invention also discloses a system of the message multiplexing on the acknowledgement indicator channel (E-HICH) and the method and system of message sending on the E-HICH, which applies the method of the message multiplexing on the acknowledgement indicator channel (E-HICH). By applying the present invention, the control and synchronization of the E-PUCH channel power in the course of non-dispatching transmission can be realized, the sending of the multi-beam shaped E-PUCH can also be realized, furthermore the control of power is realized, and the performance of the channel is increased.

Description

technical field [0001] The present invention relates to the technical field of High Speed ​​Uplink Packet Access (HSUPA) in Time Division-Synchronous Code Division Multiple Access (Time Division-Synchronous Code Division Multiple Access, TD-SCDMA), in particular to an E-HICH A message multiplexing and sending method and system. 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] HSUPA in TD-SCDMA adopts some new technologies to support these services. These new technologies include: [0004] (1). Uplink shared channels are used to improve resource utilization. [0005] (2). Several scheduling based on NodeB (base station) are adopted, and physical resources and ...
