Abstract:
1. A method for configuring physical resource when communication systems coexist, wherein, the method is applied to a situation of adjacent frequency coexistence of a World-wide Interoperability for Microwave Access (Wimax) system and a Long Term Evolution (LTE) system, and both systems using a Time Division Duplex (TDD) mode, comprising: configuring physical resources of a Wimax 16e frame according to configuration information of a LTE frame by the following modes: configuring a number of downlink symbols in the Wimax 16e frame and shift time of an initial location of the Wimax 16e frame relative to an initial location of a half frame of the LTE frame according to a constraint condition that a downlink area of the Wimax 16e frame is included in a downlink area of the LTE frame in a time domain; configuring a number of uplink symbols and a time length of a Transmission/Receive Transition Gap (TTG) in the Wimax 16e frame according to a constraint condition that an uplink area of the Wimax 16e frame is included in an uplink area of the LTE frame in the time domain, wherein, a handover period of the LTE frame is 5 ms; wherein, the step of configuring shift time of an initial location of the Wimax 16e frame relative to an initial location of a half frame of the LTE frame comprises: when a number of downlink subframes in a first half frame of the LTE frame N≧2, configuring the shift time as (N−1)ms using a forward shift mode; alternatively, configuring the shift time as (6−N)ms using a backward shift mode; when N=1, configuring the shift time as 0.
