Abstract

The present invention discloses an inter-layer scheduling method. The method includes the following steps: Step S302, the wireless terminal measures the signal quality of the first type of wireless contact and the second type of wireless contact, and reports the measurement result to the communication processing and communication processing on the network side. a control unit; and step S304, the communication processing and control unit on the network side determines according to the measurement result that the wireless terminal uses the first type of wireless contact or the second type of wireless contact. The invention also discloses a double-layer wireless access system. The system includes a communication processing and control unit for dynamically changing the traffic channel of the first type of wireless contact and the second type of wireless contact according to the measurement result obtained by the wireless terminal measuring the channel quality of the first type of wireless contact and the second type of wireless contact. The traffic channel of the second type of wireless contact is allocated to the wireless terminal. The invention realizes the optimal use of the wireless access point resources of the macro cell, and reduces the requirement for the coverage quality of the wireless access point of the micro cell and the difficulty of layout.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a double-layer wireless access system and an inter-layer scheduling method under a layered cell architecture. Background technique [0002] The invention mainly relates to the existing dispatching technology, the interlayer switching technology of the existing layered wireless access network and the diversity technology based on the layered wireless access network. [0003] In the design of HSUPA (High-Speed ​​Uplink Packet Access) and HSDPA (High-Speed ​​Downlink Packet Access) of the 3G system, in order to use the diversity gain among users to improve the throughput of the cell, the scheduling technology implemented by NodeB is adopted. The service based on NodeB scheduling is called a scheduling service, and the scheduling service is divided into an uplink scheduling service and a downlink scheduling service. In the implementation of the uplink scheduling service, before...
