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 ...

Examples

Embodiment Construction

[0028] In the method of the present invention, each user sends a reference signal known to the receiving end to the receiving end while sending the uplink data signal. The reference signal can provide the receiver with channel information for channel estimation and channel measurement information for channel measurement.

[0029] In the present invention, the reference signal and the data signal are time-division multiplexed. In a transmission time interval (transmission time interval, TTI), it is divided into one or more data signal transmission periods and reference signal transmission periods; the data signal transmission period is used to transmit data signals carrying user data to the receiving end; reference signal transmission The period is used to transmit reference signals known by the receiving end and used to obtain channel information on the transmission frequency band and channel quality measurement information on the full frequency band to the receiving end.
