A distribution method for uplink resource

Abstract

The invention relates to a method for distributing ascending resource, used in communication system with multi-user complex. Wherein, it comprises that: using time division multiplex method to divide one ascending transmission time slit into one or several data signal transmission time sections and reference signal transmission time sections; said data signal transmission time section carriers the user data to the receiver; the reference signal transmission time section transmits the reference signal known by receiver for evaluating and testing channel to the receiver; the data signal occupies the time-domain resource not layered; the reference signal occupies available frequency resource via CDMA.

Description

technical field

[0001] The present invention relates to the field of wireless communication, in particular to an uplink resource allocation method. The uplink resources include various network resources that the wireless terminal needs to occupy when sending signaling or data to the network side. Background technique

[0002] In a wireless communication system, the receiver needs to know the corresponding channel information to demodulate the data, and channel compensation by means of equalization can effectively improve the receiving performance. This is usually done by sending a reference signal carrying a known sequence at the receiver. accomplish. In a multi-user system, the wireless channel path of each user transmission is different, so the channel fading experienced by each user is also different, so that the current user has better transmission performance in some transmission frequency bands, while in some frequency bands Possibly deep decline. From the point of ...
