Wireless communication method with configuration parameters for different carriers
A recently granted patent (Publication Number: US11778636B2) describes a method for wireless devices to receive and transmit control information in a cellular network. The method involves receiving configuration parameters and information indicating the cell type from a base station. The cells in the network are categorized into two types: the first cell type and the second cell type. Cells associated with the second cell type are configured to operate without a common reference signal in downlink transmission time intervals that do not have a packet. The wireless device then transmits control information of a second cell associated with the second cell type via an uplink channel of a first cell associated with the first cell type.
The patent also includes additional claims and methods related to the skipping of common reference signals, the configuration of downlink transmission time intervals, and the presence of synchronization signals in different cell types. The wireless device is designed to receive messages from the base station indicating the location of primary and secondary synchronization signals in the second cell. The downlink transmission time intervals are referred to as subframes, and the control information is transmitted based on a downlink transmission via the second cell in one or more second downlink transmission time intervals.
The patent also covers a base station that transmits configuration parameters and information indicating the cell type to the wireless devices. The base station can skip the transmission of a common reference signal in the downlink transmission time intervals and transmit messages indicating the location of synchronization signals in the second cell.
Overall, this patent describes a method and system for efficient control information transmission in a cellular network, allowing for different cell types and the selective use of common reference signals. The invention aims to improve the performance and reliability of wireless communication systems.
