Duplex communication method, terminal scheduling method and system

A method for scheduling a terminal, comprising:

• determining capability information of a terminal when the terminal makes a request for a service, wherein the capability information includes a band for receiving a signal supported by the terminal, a band for sending a signal supported by the terminal, and a capability of the terminal sending and receiving a signal in parallel in a time division duplexing (TDD) licensed band and a frequency division duplexing (FDD) licensed band;
• allocating a band resource for the terminal according to the capability information of the terminal and currently available band resources, and sending information of the allocated band resource to the terminal in a band currently used by the terminal, wherein the allocated band resource includes a bidirectionally used band, and at least one of an uplink band and a downlink band includes a unidirectionally used band, and the unidirectionally used band is a band for unidirectional uplink transmission or a band for unidirectional downlink transmission;
• and
• communicating with the terminal in a manner of time division duplexing by way of the allocated band resource;
• wherein
• the downlink band and the uplink band are of a following relationship:
• center frequencies of the downlink band and the uplink band are different, and the downlink band and the uplink band are partially overlapped;
• or
• center frequencies of the downlink band and the uplink band are the same, and bandwidths of the downlink band and the uplink band are different.

A system for scheduling a terminal, comprising:

• a terminal, configured to:
• communicate in a manner of time division duplexing by way of an allocated band resource after receiving information of the allocated band resource;
• and
• a wireless access point, configured to:
• determine capability information of the terminal, allocate the band resource for the terminal according to the capability information of the terminal and currently available band resources, send the information of the allocated band resource to the terminal in a band currently used by the terminal, and communicate with the terminal in the manner of time division duplexing by way of the allocated band resource, wherein the capability information includes a band for receiving a signal supported by the terminal, a band for sending a signal supported by the terminal, and a capability of the terminal sending and receiving a signal in parallel in a time division duplexing (TDD) licensed band and a frequency division duplexing (FDD) licensed band, the allocated band resource includes a unidirectionally used band, and at least one of an uplink band and a downlink band includes a unidirectionally used band, wherein the unidirectionally used band is a band for unidirectional uplink transmission or a band for unidirectional downlink transmission;
• wherein
• the downlink band and the uplink band are of a following relationship:
• center frequencies of the downlink band and the uplink band are different, and the downlink band and the uplink band are partially overlapped;
• or
• center frequencies of the downlink band and the uplink band are the same, and bandwidths of the downlink band and the uplink band are different.

A wireless access point, comprising:

• a sending unit, configured to send a signal to a terminal in a downlink band within a first time interval;
• and
• a receiving unit, configured to received a signal sent by the terminal in an uplink band within a second time interval,
• the downlink band including a bidirectionally used band in a manner of time division and a unidirectional downlink band, and the uplink band only including a bidirectionally used band in the manner of time division;
• or
• the downlink band only including a bidirectionally used band in the manner of time division, and the uplink band including a bidirectionally used band in the manner of time division and a unidirectional uplink band;
• or
• the downlink band including a bidirectionally used band in the manner of time division and a unidirectional downlink band, and the uplink band including a bidirectionally used band in the manner of time division and a unidirectional uplink band;
• wherein
• the downlink band and the uplink band are of a following relationship:
• center frequencies of the downlink band and the uplink band are different, and the downlink band and the uplink band are partially overlapped;
• or
• center frequencies of the downlink band and the uplink band are the same, and bandwidths of the downlink band and the unlink band are different.
