Abstract
Embodiments of this application disclose an information transmission method and an apparatus. The method includes: sending, by a terminal to a base station, capability indication information used to indicate whether the terminal supports non-coherent joint transmission; and receiving downlink control information sent by the base station, where the downlink control information is based on the capability indication information. According to the embodiments of this application, the base station can know whether the terminal supports NCJT, so as to select an appropriate transmission mode.
Claims20
A method for information transmission comprising:
- sending, to a base station, capability indication information used to indicate whether a terminal supports non-coherent joint transmission, wherein the capability indication information is used to indicate whether the terminal supports receiving at least two pieces of downlink control information;
- receiving a parameter of the downlink control information from the base station, wherein the parameter comprises a maximum quantity of to-be-sent downlink control information and the parameter is based on the capability indication information;
- and
- receiving downlink control information from the base station, wherein the downlink control information is based on the capability indication information.
A method for information transmission comprising:
- receiving capability indication information that is received from a terminal and used to indicate whether the terminal supports non-coherent joint transmission, wherein the capability indication information is used to indicate whether the terminal supports receiving at least two pieces of downlink control information;
- determining a parameter of the downlink control information based on the capability indication information, wherein the parameter comprises a maximum quantity of to-be-sent downlink control information;
- and
- sending the downlink control information and the parameter to the terminal based on the capability indication information.
An apparatus comprising:
- a processor;
- and a memory, wherein the memory is configured to store a program code including instructions, which, when executed by the processor, causes the processor to perform a method comprising:
- sending, to a base station, capability indication information used to indicate whether a terminal supports non-coherent joint transmission, wherein the capability indication information is used to indicate whether the terminal supports receiving at least two pieces of downlink control information;
- receiving a parameter of the downlink control information from the base station, wherein the parameter comprises a maximum quantity of to-be-sent downlink control information and the parameter is based on the capability indication information;
- and
- receiving the downlink control information from the base station, wherein the downlink control information is based on the capability indication information.
An apparatus comprising:
- a processor;
- and
- a memory, wherein the memory is configured to store a program code including instructions, which, when executed by the processor, causes the processor to perform a method comprising:
- receiving capability indication information that is from a terminal and used to indicate whether the terminal supports non-coherent joint transmission, wherein the capability indication information is used to indicate whether the terminal supports receiving at least two pieces of downlink control information;
- determining a parameter of the downlink control information based on the capability indication information and whether a base station supports the non-coherent joint transmission, wherein the parameter comprises a maximum quantity of to-be-sent downlink control information;
