Abstract
The present disclosure relates to a method for operating a base station of a wireless communication network. Precoding information for concentrating a radio-frequency power of a transmitted radio-frequency signal to a group of terminal devices arranged in a sub area of a coverage area of the base station is determined and applied to an antenna array of the base station. A synchronization signal is transmitted from the base station to the group of terminal devices using the precoding information.
Claims13
A method for operating a base station of a wireless communication network, the base station comprising an antenna array having a plurality of antennas configured to communicate wirelessly with terminal devices positioned within a coverage area of the base station, a spatial transmission characteristic of the antenna array being configurable by applying precoding information, the method comprising:
- determining the precoding information for concentrating a radio frequency power of a transmitted radio frequency signal to a group of terminal devices arranged in a sub area of the coverage area of the base station,
- applying the determined precoding information to the antenna array,
- transmitting, from the base station to the group of terminal devices, a synchronization signal using the precoding information,
- receiving time interval information from at least one terminal device of the group of terminal devices, the time interval information indicating a required maximum time interval for synchronizing the at least one terminal device, and
- determining schedule information indicating a schedule for transmitting the synchronization signal using the precoding information.
A base station, comprising:
- an antenna array having a plurality of antennas configured to communicate wirelessly with terminal devices positioned within a coverage area of the base station, a spatial transmission characteristic of the antenna array being configurable by applying precoding information, and
- a control unit configured
- to determine precoding information for concentrating a radio frequency power of a transmitted radio frequency signal to a group of terminal devices arranged in a sub area of the coverage area of the base station,
- to apply the determined precoding information to the antenna array,
- to transmit a synchronization signal using the precoding information,
- to receive time interval information from at least one terminal device of the group of terminal devices, the time interval information indicating a required maximum time interval for synchronizing the at least one terminal device, and
- to determine schedule information indicating a schedule for transmitting the synchronization signal using the precoding information.
A terminal device, comprising
- at least one antenna configured to wirelessly communicate with a base station of a wireless communication network,
- a synchronization control unit configured
- to receive a sequence of synchronization signals from the base station,
- to acquire timing and/or frequency information of the base station based on the synchronization signals, and
- to transmit time interval information to the base station, the time interval information indicating a required maximum time interval for synchronizing the terminal device.
