Abstract
A method of operating a lower-layer split central unit, LLS-CU, includes allocating a plurality of downlink signals to a plurality of physical resource blocks, PRBs, of a physical downlink channel, generating a data-associated control information, DACI, message including a section description associated with the plurality of downlink signals, the DACI message including an indication of a plurality of sets of beamforming weights to be applied by a radio unit, RU, when transmitting the plurality of downlink signals to the UE, transmitting the DACI message to the RU, and transmitting the plurality of downlink signals to the RU for transmission to the UE.
Claims18
A method of operating a lower-layer split central unit (LLS-CU) in a network node of a wireless communication system, comprising:
- providing, at the LLS-CU, a plurality of downlink signals to be transmitted to a user equipment (UE) over a wireless radio interface;
- allocating the plurality of downlink signals to a plurality of physical resource blocks (PRBs) of a physical downlink channel of the wireless radio interface to be used for transmitting the plurality of downlink signals to the UE;
- generating a data-associated control information (DACI) message including a section description associated with the plurality of downlink signals, the DACI message including an indication of a plurality of sets of beamforming weights to be applied by a radio unit (RU) when transmitting the plurality of downlink signals to the UE;
- transmitting the DACI message to the RU;
- and
- transmitting the plurality of downlink signals to the RU for transmission to the UE.
A lower-layer split central unit (LLS-CU) in a network node of a wireless communication system, comprising:
- a processor circuit;
- a transceiver coupled to the processor circuit and configured to communicate with a radio unit (RU);
- and
- a memory coupled to the processor circuit, the memory comprising machine readable program instructions that, when executed by the processor circuit, cause the LLS-CU to perform operations comprising:
- providing, at the LLS-CU, a plurality of downlink signals to be transmitted to a user equipment (UE) over a wireless radio interface;
- allocating the plurality of downlink signals to a plurality of physical resource blocks (PRBs) of a physical downlink channel of the wireless radio interface to be used for transmitting the plurality of downlink signals to the UE;
- generating a data-associated control information (DACI) message including a section description associated with the plurality of downlink signals, the DACI message including an indication of a plurality of sets of beamforming weights to be applied by the RU when transmitting the plurality of downlink signals to the UE;
- transmitting the DACI message to the RU;
- and
- transmitting the plurality of downlink signals to the RU for transmission to the UE.
A non-transitory computer-readable medium comprising computer-readable instructions which, when executed by a processor, cause the processor to perform operations comprising:
- providing a plurality of downlink signals to be transmitted to a user equipment (UE) over a wireless radio interface;
- allocating the plurality of downlink signals to a plurality of physical resource blocks (PRBs) of a physical downlink channel of the wireless radio interface to be used for transmitting the plurality of downlink signals to the UE;
- generating a data-associated control information (DACI) message including a section description associated with the plurality of downlink signals, the DACI message including an indication of a plurality of sets of beamforming weights to be applied by a radio unit (RU) when transmitting the plurality of downlink signals to the UE;
- transmitting the DACI message to the RU;
- and
- transmitting the plurality of downlink signals to the RU for transmission to the UE.
