Abstract

The invention discloses a method for a user terminal to access network by a radio relay, comprising steps that: at first, the base station determines whether there is enough resource for supporting access of the user terminal according to the cell resource using situation and the bandwidth request information forwarded by a relay station and sent by a user terminal, if so, the base station feeds back an access permission response information to the relay station, and distributes corresponding channel resources to an access link and a relay link; the access permission response information received relay station forwards the response information to the user terminal, and the user terminal receives the response information from the response information from the relay station, determines the final object relay station and the object base station, sends a relay starting command to the object relay station, and gets access to the network. Applying the method, network access by user terminals in cross-covered region at edge of multiple cells is implemented by the relay of the radio relay station.

Description

technical field

[0001] The invention relates to a cellular relay communication system, in particular to a method for a user terminal to access a network through a wireless relay. Background technique

[0002] With the commercialization of 3G systems, B3G / 4G technologies with higher speed, higher spectrum efficiency, higher coverage and stronger service support capabilities have entered the standardization stage. ITU plans to complete the B3G spectrum planning in 2007, and in 2010 The main standards were completed in 2012, commercial use began in 2012, and large-scale commercial use began in 2015. B3G / 4G requires that the transmission rate can reach 1Gbps, and the required spectrum is at least 100MHz. It is difficult to find such broadband spectrum requirements in existing frequency bands, so a higher frequency band, such as 5GHz or 6GHz, needs to be allocated to B3G / 4G.

[0003] Although increasing the working frequency band can solve the frequency allocation problem of B3...
