Abstract
The present disclosure relates to data transmission methods, terminal devices, and base station systems. In one example method, a base station sends information about a first control resource set and information about a second control resource set to a terminal device. The terminal device detects first control information in a first control channel candidate set, and detects second control information in a second control channel candidate set.
Claims17
A data transmission method, wherein the method comprises:
- receiving, by a terminal device, first configuration information and second configuration information from a base station, wherein the first configuration information comprises information about a first control resource set, and wherein the second configuration information comprises information about a second control resource set;
- detecting, by the terminal device, first control information in a first control channel candidate set corresponding to the first control resource set;
- and
- in response to successfully detecting the first control information in the first control channel candidate set corresponding to the first control resource set, detecting, by the terminal device, second control information in a second control channel candidate set corresponding to the second control resource set, wherein a sum of a size of the first control channel candidate set and a size of the second control channel candidate set is not greater than a first threshold.
A terminal device, comprising:
- a transceiver, the transceiver configured to receive first configuration information and second configuration information from a base station, wherein the first configuration information comprises information about a first control resource set, and wherein the second configuration information comprises information about a second control resource set;
- and
- at least one processor, the at least one processor configured to:
- detect first control information in a first control channel candidate set corresponding to the first control resource set;
- and
- in response to successfully detecting the first control information in the first control channel candidate set corresponding to the first control resource set, detect second control information in a second control channel candidate set corresponding to the second control resource set, wherein a sum of a size of the first control channel candidate set and a size of the second control channel candidate set is not greater than a first threshold.
A base station system, comprising a first base station and a second base station, wherein:
- the first base station is configured to:
- send first configuration information and second configuration information to a terminal device, wherein the first configuration information comprises information about a first control resource set, and wherein the second configuration information comprises information about a second control resource set;
- and
- send first control information to the terminal device in a first control channel candidate set corresponding to the first control resource set;
- and
- the second base station is configured to:
- send second control information to the terminal device in a second control channel candidate set corresponding to the second control resource set, wherein a sum of a size of the first control channel candidate set and a size of the second control channel candidate set is not greater than a first threshold.
