Abstract
Embodiments of this application provide a parameter determining method, a base station, and user equipment. The parameter determining method provided in this application includes: determining, by a base station, a first subcarrier spacing corresponding to UE; and notifying, by the base station, the UE of the first subcarrier spacing. In the embodiments of this application, the UE may accurately learn of, in a multi-subcarrier-spacing system, a subcarrier spacing used for data transmission, and then perform data transmission. This can effectively ensure that the UE performs a corresponding service, thereby meeting a corresponding service requirement.
Claims25
-24. (canceled)
A method, comprising:
- receiving first information from a base station via a broadcast channel, wherein the first information indicates a first subcarrier spacing, and the first subcarrier spacing is to be used for a common channel;
- receiving system information from the base station via a physical downlink shared channel, wherein the system information comprises second information indicating a second subcarrier spacing;
- and
- sending a random access channel to the base station based on the second subcarrier spacing.
An apparatus, comprising:
- a processor;
- and
- a non-transitory memory coupled to the processor and storing program instructions;
- wherein the program instructions, when executed by the processor, cause the apparatus to:
- receive first information from a base station via a broadcast channel, wherein the first information indicates a first subcarrier spacing, and the first subcarrier spacing is to be used for a common channel;
- receive system information from the base station via a physical downlink shared channel, wherein the system information comprises second information indicating a second subcarrier spacing;
- and
- send a random access channel to the base station based on the second subcarrier spacing.
A method, comprising:
- sending first information to a terminal via a broadcast channel, wherein the first information indicates a first subcarrier spacing, and the first subcarrier spacing is to be used for a common channel;
- sending system information to the terminal via a physical downlink shared channel, wherein the system information comprises second information indicating a second subcarrier spacing;
- and
- receiving a random access channel from the terminal based on the second subcarrier spacing.
An apparatus, comprising:
- a processor;
- and
- a non-transitory memory coupled to the processor and storing program instructions;
- wherein the program instructions, when executed by the processor, cause the apparatus to:
- send first information to a terminal via a broadcast channel, wherein the first information indicates a first subcarrier spacing, and the first subcarrier spacing is to be used for a common channel;
- send system information to the terminal via a physical downlink shared channel, wherein the system information comprises second information indicating a second subcarrier spacing;
- and
- receive a random access channel from the terminal based on the second subcarrier spacing.
