Embodiment Construction

[0072] The present invention adopts the channel tree structure in the prior art to manage wireless resources and allocate them to user terminals. The specific persistent resource allocation method is described as follows:

[0073] The present invention divides the channel ID into the following four categories:

[0074] Part of the wireless resources indicated by the channel ID of the first type belong to persistent resources currently occupied by a user terminal;

[0075] All wireless resources indicated by the channel ID of the second type do not belong to the current persistent resource of a user terminal;

[0076] The wireless resources indicated by the channel ID of the third type all belong to the persistent resources currently occupied by a user terminal;

[0077] The wireless resources indicated by the fourth type of channel ID may be available wireless resources;

[0078] Among them, the first type of channel ID is a newly added type of the present invention, and the...

Abstract

This invention discloses an assigning method for persistent occupied resources including: a base station sends a message assigning a first kind of persistent occupied resource to a UE carrying with ID of a first kind of channels and takes a supplement field in the message valid, in which, part of radio resource instructed by the ID of the first kind channels belongs to the currently occupied persistent resource of the UE, after receiving the assigning message, the UE releases the resource occupied currently same to the that in the instructed first channel ID and increases other resources not belonging to the persistent one of the UE as its own persistent resource. This invention also discloses related base stations, UE and a radio system.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method for assigning persistent resources (persistent resources) in an OFDM mobile communication system using Orthogonal Frequency Division Multiplexing (OFDM) technology, and corresponding base stations, User terminals and wireless systems. Background technique [0002] OFDM technology is a physical layer technology adopted in Air Interface Evolution (AIE) Phase 2 Mobile Broadband Wireless Access (MBWA) of 3GPP2. OFDM technology divides the physical layer resources in the wireless communication system into several orthogonal narrowband sub-carriers in the frequency domain, and high-speed data streams are transmitted in parallel on each sub-carrier through serial-to-parallel conversion. Due to the narrowband characteristics of the sub-carriers, it can overcome the influence of multipath and greatly eliminate the interference between symbols; due to the orthogonal ...
