Abstract
In a control information transmission method according to present disclosure, a user equipment acquires configuration information of an enhanced physical downlink control channel (EPDCCH) set. The user equipment determines, according to the configuration information and from the EPDCCH set, at least one EPDCCH set in which an EPDCCH needs to be monitored. The user equipment monitors an EPDCCH on a resource corresponding to the at least one EPDCCH set, to acquire control information sent by a base station.
Claims20
A method, comprising:
- sending, by a network device, a broadcast message on a broadcast channel, wherein the broadcast message comprises location indication information of a first resource;
- sending, by the network device, first downlink control information on a first physical downlink control channel in the first resource, wherein the first downlink control information indicates configuration information of at least two physical downlink control channel sets;
- sending, by the network device, transmission bandwidth configuration information, wherein the transmission bandwidth configuration information indicates a transmission bandwidth of a terminal device;
- and
- determining, by the network device, according to the transmission bandwidth of the terminal device, at least one physical downlink control channel set from the at least two physical downlink control channel sets corresponding to the configuration information;
- and
- sending, by the network device, second control information on a second physical downlink control channel in the at least one physical downlink control channel set.
An apparatus, comprising:
- at least one processor;
- and
- a non-transitory computer-readable storage medium coupled to the at least one processor and storing programming instructions for execution by the at least one processor, wherein the programming instructions instruct the at least one processor to:
- send a broadcast message on a broadcast channel, wherein the broadcast message comprises location indication information of a first resource;
- send first downlink control information on a first physical downlink control channel in the first resource, wherein the first downlink control information indicates configuration information of at least two physical downlink control channel sets;
- send transmission bandwidth configuration information, wherein the transmission bandwidth configuration information indicates a transmission bandwidth of a terminal device;
- determine at least one physical downlink control channel set from the at least two physical downlink control channel sets corresponding to the configuration information according to the transmission bandwidth of the terminal device;
- and
- send second control information on a second physical downlink control channel in the at least one physical downlink control channel set.
A non-transitory computer readable medium, having computer-executable instructions stored thereon, wherein the instructions when executed by a network device, cause the network device to implement operations comprising:
- sending a broadcast message on a broadcast channel, wherein the broadcast message comprises location indication information of a first resource;
- sending first downlink control information on a first physical downlink control channel in the first resource, wherein the first downlink control information indicates configuration information of at least two physical downlink control channel sets;
- sending transmission bandwidth configuration information, wherein the transmission bandwidth configuration information indicates a transmission bandwidth of a terminal device;
- determining at least one physical downlink control channel set from the at least two physical downlink control channel sets corresponding to the configuration information according to the transmission bandwidth of the terminal device;
- and
- sending second control information on a second physical downlink control channel in the at least one physical downlink control channel set.
