DOWNLINK CONTROL AND DATA CHANNEL CONFIGURATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 18249761 titled 'DOWNLINK CONTROL AND DATA CHANNEL CONFIGURATION

Simplified Explanation

This patent application is about a method for configuring downlink control and data channels in a wireless communication system. Here are the key points:

  • The method involves determining the transmission scheme of control information for a second device based on certain criteria related to multicast and broadcast services.
  • The control information is related to scheduling multicast service traffic to the second device.
  • Configuration information is transmitted to the second device to enable it to obtain the control information.
  • The control information is then transmitted to the second device on a control channel between the first and second devices, based on the determined transmission scheme.
  • This decouples the scheduling mechanism of multicast traffic on the downlink data channel from the transmission mechanism of control information on the downlink control channel.
  • The result is a more flexible and dynamic downlink channel configuration and increased efficiency of radio resources.


Original Abstract Submitted

Embodiments of the present disclosure relate to downlink control and data channel configuration. A method comprises: determining, at a first device, a transmission scheme of control information for a second device based on at least one multicast and broadcast service related criterion, the control information related to scheduling multicast service traffic to the second device; transmitting, to the second device, configuration information for causing the second device to obtain the control information; and transmitting, to the second device and based on the determined transmission scheme, the control information on a control channel between the first device and the second device. In this way, the correlation between the scheduling mechanism of multicast traffic on the downlink data channel and the transmission mechanism of control information on the downlink control channel can be decoupled, resulting in a flexible and dynamic downlink channel configuration and an increased radio resource efficiency.
