Abstract
Embodiments of the present disclosure provide an uplink access method, a base station, and user equipment. The method includes: sending, by a base station, N signals and N pieces of physical random access channel PRACH resource indication information, where N is an integer greater than or equal to 2; and receiving, by the base station, a random access preamble sequence of the user equipment on PRACH resources indicated by the N pieces of PRACH resource indication information. Based on the foregoing solution, a quantity of random access preamble sequences sent by the user equipment is reduced, and uplink access complexity is reduced.
Claims16
An uplink access method, comprising:
- receiving, by user equipment, N signals and N pieces of physical random access channel (PRACH) resource indication information, wherein N is an integer greater than or equal to 2, and wherein an ith piece of PRACH resource indication information is carried in an ith channel, a time-frequency-code resource used by an ith signal has a preset relationship with a time-frequency-code resource used by the ith channel, and i is an integer that is greater than or equal to 1 and less than or equal to N;
- and
- selecting, by the user equipment, a PRACH resource, and sending a random access preamble sequence by using the PRACH resource.
A base station, comprising:
- a transmitter and a receiver wherein
- the transmitter is configured to send N signals and N pieces of physical random access channel (PRACH) resource indication information, wherein N is an integer greater than or equal to 2, and wherein an ith piece of PRACH resource indication information is carried in an ith channel, a time-frequency-code resource used by an ith signal has a preset relationship with a time-frequency-code resource used by the ith channel, and i is an integer that is greater than or equal to 1 and less than or equal to N;
- and
- the receiver is configured to receive a random access preamble sequence of a user equipment on PRACH resources indicated by the N pieces of PRACH resource indication information.
A user equipment apparatus, comprising:
- a receiver and a transmitter, wherein
- the receiver is configured to receive N signals and N pieces of physical random access channel (PRACH) resource indication information, wherein M is an integer greater than or equal to 2, and wherein an ith piece of PRACH resource indication information is carried in an ith channel, a time-frequency-code resource used by an ith signal has a preset relationship with a time-frequency-code resource used by the ith channel, and i is an integer that is greater than or equal to 1 and less than or equal to N;
- the processor is configured to select a PRACH resource;
- and
- the transmitter is configured to send a random access preamble sequence by using the PRACH resource.
