Abstract
A method includes: determining, by an access network device, at least one piece of downlink control information, where the downlink control information includes at least one slot format indication; and sending, by the access network device, the downlink control information to a group of user equipment on a group common downlink control channel, where the group of user equipment operates in M bandwidth parts, the at least one slot format indication is used to indicate a slot format corresponding to N numerologies of the M bandwidth parts, and both N and M are positive integers greater than 1.
Claims14
A method, comprising:
- receiving downlink control information, wherein the downlink control information is received using a group common downlink control channel, the downlink control information indicates a reference slot format, the reference slot format corresponds to a reference numerology, and the group common downlink control channel is common to a group of user equipment (UEs);
- and
- determining, based on the reference numerology, the reference slot format, and a numerology corresponding to a bandwidth part, a slot format corresponding to the bandwidth part;
- wherein the group of UEs operates in M bandwidth parts, the reference slot format is for a reference numerology in N numerologies of the M bandwidth pails, wherein both N and M are positive integers greater than 1, and wherein:
- a value of N corresponds to a frequency range;
- or
- the value of N is indicated using a physical broadcast channel or a system message.
An apparatus, comprising:
- a transceiver, configured to receive downlink control information, wherein the downlink control information is received using a group common downlink channel, the downlink control information indicates a reference slot format, the reference slot format corresponds to a reference numerology, and the group common downlink channel is common to a group of user equipment (UEs);
- a processor;
- and
- a non-transitory computer-readable storage medium storing a program to be executed by the processor, the program including instructions for:
- determining, based on the reference numerology, the reference slot format, and a numerology corresponding to a bandwidth part, a slot format corresponding to the bandwidth part;
- wherein the group of UEs operates in M bandwidth parts, the reference slot format is for a reference numerology in N numerologies of the M bandwidth pails, wherein both N and M are positive integers greater than 1, and wherein:
- a value of N corresponds to a frequency range;
- or
- the value of N is indicated using a physical broadcast channel or a system message.
A non-transitory computer-readable medium comprising instructions which, when executed by a computer, cause the computer to:
- receive downlink control information, wherein the downlink control information is received using a group common downlink control channel, the downlink control information indicates a reference slot format, the reference slot format corresponds to a reference numerology, and the group common downlink control channel is common to a group of user equipment (UEs);
- and
- determine, based on the reference numerology, the reference slot format, and a numerology corresponding to a bandwidth part, a slot format corresponding to the bandwidth part;
- wherein the group of UEs operates in M bandwidth parts, the reference slot format is for a reference numerology in N numerologies of the M bandwidth pails, wherein both N and M are positive integers greater than 1, and wherein:
- a value of N corresponds to a frequency range;
- or
- the value of N is indicated using a physical broadcast channel or a system message.
