DYNAMIC CONFIGURATION OF SUBFRAMES IN A RADIO COMMUNICATIONS SYSTEM

摘要

The technology disclosed provides the ability for a subframe to be dynamically configured in time division duplex (TDD) communications between a UE radio terminal and a radio network node. A frame structure includes one or more subframes preconfigured as a downlink subframe, one or more subframes preconfigured as an uplink subframe, and one or more dynamically configurable subframes. Each dynamically configurable subframe includes a guard time period and at least a downlink part for transporting a dynamically configurable amount of downlink information, and in some embodiments, uplink information. A configuration for dynamically configurable subframes is determined for transmission and/or reception between the UE radio terminal and the radio network node.

1. A radio network node for use in a radio communications network using time division duplex (TDD) to communicate with user equipment (UE) radio terminals, comprising:
electronic circuitry configured to:
process data for a frame structure that includes one or more subframes preconfigured as a downlink subframe, one or more subframes preconfigured as an uplink subframe, and one or more dynamically configurable subframes, each dynamically configurable subframe including a guard time period and at least a downlink part for transporting a dynamically configurable amount of downlink information, wherein the length of the guard time period and of the downlink part is dynamically configurable and determine a configuration for one or more dynamically configurable subframes; radio receive circuitry; and radio transmit circuitry configured to
signal information about the determined configuration for one or more dynamically configurable subframes to the user equipment radio terminals on a control channel; andtransmit information in a downlink part of dynamically configurable subframes.
