DOWNLINK CONTROL CHANNEL DESIGN AND SIGNALING FOR BEAMFORMED SYSTEMS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240276510 titled 'DOWNLINK CONTROL CHANNEL DESIGN AND SIGNALING FOR BEAMFORMED SYSTEMS

Abstract: The patent application discusses the application of transmit and/or receive beamforming to the control channel transmission/reception in mmw access link system design. Techniques are proposed to identify candidate control channel beams and their location in the subframe structure to enhance the efficiency of WTRU operation. A framework for beam-formed control channel design is outlined to support varying capabilities of MBS and/or WTRUs, as well as time and/or spatial domain multiplexing of control channel beams. Modifications to reference signal design in a multi-beam system may help discover, identify, measure, and/or decode a control channel beam while mitigating inter-beam interference. WTRU monitoring may involve considering beam search space in addition to time and/or frequency search space. Enhancements to downlink control channel may facilitate scheduling narrow data beams to achieve high resource utilization, especially with large available bandwidths and spatially distributed WTRUs.

Original Abstract Submitted

transmit and/or receive beamforming may be applied to the control channel transmission/reception, e.g., in mmw access link system design. techniques to identify candidate control channel beams and/or their location in the subframe structure may provide for efficient wtru operation. a framework for beam formed control channel design may support varying capabilities of mbs and/or wtrus, and/or may support time and/or spatial domain multiplexing of control channel beams. for a multi-beam system, modifications to reference signal design may discover, identify, measure, and/or decode a control channel beam. techniques may mitigate inter-beam interference. wtru monitoring may consider beam search space, perhaps in addition to time and/or frequency search space. enhancements to downlink control channel may support scheduling narrow data beams. scheduling techniques may achieve high resource utilization, e.g., perhaps when large bandwidths are available and/or wtrus may be spatially distributed.
