Abstract
A method and apparatus for random access on an unlicensed spectrum, and a storage medium involve: a terminal acquiring a beacon frame sent by a WLAN AP working on n available spectrums for random access, n being a positive integer; the terminal selecting, according to channel indication information included in the beacon frame, a first available spectrum for random access from among the n available spectrums for random access; and the terminal initiating random access on the first available spectrum for random access.
Claims13
A method for random access in an unlicensed frequency band, comprising:
- acquiring, by a terminal, beacon frames from Wireless Local Area Network Access Points (WLAN APs) operating on n random access available frequency bands, wherein a random access available frequency band is a frequency band, in the unlicensed frequency band, available for the terminal to initiate the random access, and n is a positive integer;
- selecting, by the terminal, a first random access available frequency band from the n random access available frequency bands based on channel indication information in respective beacon frames, wherein channel indication information in a beacon frame sent by a WLAN AP operating on an i-th random access available frequency band indicates a channel congestion level of the i-th random access available frequency band, and i is a positive integer less than or equal to n;
- and
- initiating, by the terminal, the random access in the first random access available frequency band.
A device for random access in an unlicensed frequency band, applied to a terminal, the device comprising:
- a receiver;
- a processor;
- and
- a memory for storing instructions executable by the processor,
- wherein the processor is configured to execute the instructions to:
- control the receiver to acquire beacon frames from Wireless Local Area Network Access Points (WLAN APs) operating on n random access available frequency bands, wherein a random access available frequency band is a frequency band, in the unlicensed frequency band, available for the terminal to initiate the random access, and n is a positive integer;
- select a first random access available frequency band from the n random access available frequency bands based on channel indication information in respective beacon frames, wherein channel indication information in a beacon frame sent by a WLAN AP operating on an i-th random access available frequency band indicates a channel congestion level of the i-th random access available frequency band, and i is a positive integer less than or equal to n;
- and
- initiate the random access in the first random access available frequency band.
-11. (canceled)
A non-transitory computer-readable storage medium having stored thereon a computer program which, when being executed by a processor, causes the processor to implement a method for random access in an unlicensed frequency band, the method comprising:
- acquiring beacon frames from Wireless Local Area Network Access Points (WLAN APs) operating on n random access available frequency bands, wherein a random access available frequency band is a frequency band, in the unlicensed frequency band, available for a terminal to initiate the random access, and n is a positive integer;
- selecting a first random access available frequency band from the n random access available frequency bands based on channel indication information in respective beacon frames, wherein channel indication information in a beacon frame sent by a WLAN AP operating on an i-th random access available frequency band indicates a channel congestion level of the i-th random access available frequency band, and i is a positive integer less than or equal to n;
- and
- initiating the random access in the first random access available frequency band.
