摘要： An adaptive time division duplexing (ATDD) method and apparatus for duplexing transmissions on a communication link in wireless communication systems. Communication link efficient is enhanced by dynamically adapting to the uplink and downlink bandwidth requirements of the communication channels. Time slots are flexibly and dynamically allocated for uplink or downlink transmissions depending upon the bandwidth needs of a channel. Communication link bandwidth requirements are continuously monitored using sets of predetermined bandwidth requirement parameters. Communication channels are configured to have either symmetric or asymmetric uplink/downlink bandwidths depending upon the needs of the channel. Channel bandwidth asymmetry can be configured alternatively in favor of the uplink transmissions (i.e., more time slots are allocated for uplink transmissions than for downlink transmissions) or in favor of the downlink transmissions (i.e., more time slots are allocated for downlink transmissions than for uplink transmissions). A myriad of time slot allocation schemes are possible. One simplified time slot allocation scheme uses a “frame-based” approach. A preferred channel bandwidth analysis technique is disclosed which monitors and updates bandwidth requirement parameters associated with communication sessions, base stations and cell cluster controllers. In accordance with this technique, a communication session is preferably assigned both an “initial” and an “actual” set of bandwidth parameters.

摘要： A radio communication apparatus in a radio packet communication system constituted by a plurality of radio stations and having a plurality of radio channels is provided. To allow radio stations belonging to different radio links to directly communicate with each other, when a packet as data is to be transmitted, a channel control section (101) inquires of a channel registration section (102) about a radio channel used for reception by a radio station corresponding to the destination address in input transmission data, and a radio channel used for packet transmission is selected. The packet is then transmitted from a transmission/reception section (103) via the selected radio channel. When a packet is to be received, the radio channel in the transmission/reception section (103) is switched to the self-station radio channel stored in a self-station channel storage section (104).
