Abstract

The invention discloses a wireless access network, a terminal, a frequency spectrum using/multiplexing method and a communication implementation method. The frequency spectrum using method comprises the following steps that: working bands of a radio frequency receiving channel and a radio frequency emission channel of the terminal are configured to simultaneously cover a frequency band of a time division duplex TDD system and a frequency band, which is adjacent to the frequency band of the time division duplex TDD system, of a frequency division duplex FDD system; the terminal transmits data on the configured working bands. By configuring the used frequency spectrum of the wireless access network, the wireless access network, the terminal, the frequency spectrum using/multiplexing method and the communication implementation method of the invention solve the configuration problem of carriers special for an MBMS and allow a plurality of wireless access networks to provide services to respective user in parallel, thereby improving the service efficiency of the frequency spectrum and support ability of breaking through the services.

Description

technical field [0001] The present invention relates to the communication field, in particular to a wireless access network system, a terminal, a frequency spectrum usage / multiplexing method, and a communication implementation method. Background technique [0002] The Long Term Evolution (LTE for short) system standard formulated by the 3rd Generation Partnership Project (3GPP for short) includes the following systems: Time Division Duplexing (Time Division Duplexing for short) A system that works in TDD mode, a system that works in Frequency Division Duplex (FDD) mode, and a multimedia broadcast multicast service system (Multi-cast and Broadcast Multimedia System, referred to as MBMS) that works in a dedicated downlink carrier mode . [0003] At present, in the 3GPP system, according to the situation of adjacent channel interference, the feasibility of using the TDD spectrum in the three frequency bands of 1900-1920MHz, 2010-2025MHz, and 2570-2620MHz for MBMS is analyzed. ...
