Abstract
Embodiments of the present disclosure relate to methods, devices and computer storage media for communication. A method comprises transmitting, from a network device to a terminal device, a set of repetitions of downlink control information (DCI) for scheduling data transmissions from the network device to the terminal device; performing, based on the set of repetitions of the DCI, the data transmissions from the network device to the terminal device; and receiving, from the terminal device, a single feedback signal for the data transmissions. Embodiments of the present disclosure can improve reliability and robustness for Physical Downlink Control Channel (PDCCH).
Claims12
A method of communication, the method comprising:
- transmitting, from a network device to a terminal device, a plurality of Physical Downlink Control Channel (PDCCH) candidates, the plurality of PDCCH candidates corresponding to downlink control information (DCI) for scheduling a transmission from the terminal device to the network device, wherein each of the plurality of PDCCH candidates comprises a same transmission power control (TPC) command for power control of the transmission;
- decoding the transmission from the terminal device, wherein power of the transmission is controlled based on the same TPC command comprised in one of the plurality of PDCCH candidates.
A method of communication, the method comprising:
- receiving, at a terminal device and from a network device, a plurality of PDCCH candidates, the plurality of Physical Downlink Control Channel (PDCCH) candidates corresponding to downlink control information (DCI) for scheduling a transmission from the terminal device to the network device, wherein each of the plurality of PDCCH candidates comprises a same transmission power control (TPC) command for power control of the transmission;
- detecting, from the plurality of PDCCH candidates, the DCI with the same TPC command;
- controlling, based on the TPC command, power of the transmission from the terminal device to the network device.
A network device, comprising:
- at least one memory having program instructions stored therein;
- at least one processor configured to execute the program instructions, that when executed performs a method comprising:
- transmitting, to a terminal device, a plurality of Physical Downlink Control Channel (PDCCH) candidates, the plurality of PDCCH candidates corresponding to downlink control information (DCI) for scheduling a transmission from the terminal device to the network device, wherein each of the plurality of PDCCH candidates comprises a same transmission power control (TPC) command for power control of the transmission;
- decoding the transmission from the terminal device, wherein power of the transmission is controlled based on the same TPC command comprised in one of the plurality of PDCCH candidates.
A terminal device, comprising:
- at least one memory having program instructions stored therein;
- at least one processor configured to execute the program instructions, that when executed performs a method comprising:
- receiving, from a network device, a plurality of Physical Downlink Control Channel (PDCCH) candidates, the plurality of PDCCH candidates corresponding to downlink control information (DCI) for scheduling a transmission from the terminal device to the network device, wherein each of the plurality of PDCCH candidates comprises a same transmission power control (TPC) command for power control of the transmission;
- detecting, from the plurality of PDCCH candidates, the DCI with the same TPC command;
- controlling, based on the TPC command, power of the transmission from the terminal device to the network device.
