Dynamic allocation of subframe scheduling for time divison duplex operation in a packet-based wireless communication system

摘要

Systems and methods for enabling the dynamic allocation of certain sub frames as downlink or uplink resources in a time division duplexed over the air communications system. A base station or eNB may allocate certain subframes within a repeating radio frame of a TDD configuration as either DL or UL subframes for communicating to user equipment or UE devices to increase efficient use of system resources based on the data to be transmitted. Methods for determining the capabilities of a selected UE and based on the determining step, dynamically allocating certain subframes are disclosed. The methods and systems are compatible with user equipment that does not support the dynamic allocation of subframes.

1. A method, comprising:
receiving, at a user equipment over an air interface in one or more fixed downlink subframes from a node, a subframe allocation for a time division duplex frame comprising at least one fixed subframe and a plurality of flexible subframes, the subframe allocation identifying a plurality of flexible subframes and indicating an assignment for each of the plurality of flexible subframes as an uplink subframe or a downlink subframe, the assignment based on an indication received at the node indicating whether the user equipment supports dynamic allocation of subframes; and forming, by the user equipment, a subframe pattern that includes at least one fixed uplink subframe, at least one fixed downlink subframe, and a plurality of flexible subframes, each flexible subframe allocated as an uplink subframe or a downlink subframe based on the received subframe allocation.
