METHOD FOR PREDETERMINING RESOURCE IN RANDOM ACCESS, USER EQUIPMENT, AND BASE STATION |
摘要 |
Embodiments of the present disclosure relate to the communications field, and provide a method for predetermining a resource in random access, user equipment, and a base station, so that a process of random access can be simplified, and reliability of information transmission in the process of random access can be improved. The method is: an implicit manner is used to indicate some or all of identifiers of a random access preamble index; so that a message in a procedure of random access is simplified, and at the same time resources used for transmitting an RAR reply message, transmitting a contention resolution message, retransmitting an RAR reply message, and retransmitting a contention resolution message are configured by using signaling or preset by a system. The embodiments of the present disclosure are used for a process of random access. |

1. A method for predetermining a resource in a process of random access, wherein the method comprises:
receiving a random access preamble sent by user equipment, and determining preamble information according to the received random access preamble, wherein the preamble information comprises one or more of the following: the random access preamble, a random access preamble index, an index of a time resource used for transmitting the random access preamble, an index of a frequency resource used for transmitting the random access preamble, a start time resource in the time resource used for transmitting the random access preamble, and a start frequency resource used for transmitting the random access preamble; determining an RAR resource corresponding to the random access preamble according to a correspondence between the preamble information and random access response RAR resource information, wherein the RAR resource information comprises one or more of the following: the RAR resource, an RAR resource index, an index of a time resource used for transmitting an RAR message, an index of a frequency resource used for transmitting the RAR message, a start time resource in the time resource used for transmitting the RAR message, and a start frequency resource used for transmitting the RAR message, and the correspondence between the preamble information and the RAR resource information is configured by using signaling or preset by a system; and sending the RAR message corresponding to the random access preamble to the user equipment on the RAR resource corresponding to the random access preamble. |
