Method and system for allocating random access channel resource
First Claim
1. A method for allocating random access channel resources, comprising:
- a first node sending random access channel configuration information through a downlink channel, wherein the information comprises at least configuration information of a random access channel allocated to a second node;
wherein the method further comprises;
dividing second nodes into one or more sets based on different coverage improvement targets that need to be supported, one second node in each set corresponds to one coverage improvement level;
wherein a value range of a coverage improvement target corresponding to each coverage improvement level is determined by a number of coverage improvement levels and a maximum value of the coverage improvements and in accordance with a predefined rule;
or,the value range of the coverage improvement target corresponding to each coverage improvement level is determined by the number of coverage improvement levels, the maximum value of the coverage improvements and a minimum value of the coverage improvements and in accordance with the predefined rule;
wherein the predefined rule is any of the following;
the value range of the coverage improvement target corresponding to each coverage improvement level is equal and has no overlapping, and value ranges of all coverage improvement targets which are put together are the same as a range from the minimum value of coverage improvement targets to the maximum value of coverage improvement targets;
the value range of the coverage improvement target corresponding to each coverage improvement level is equal and has no overlapping, and value ranges of all coverage improvement targets which are put together are less than the range from the minimum value of coverage improvement targets to the maximum value of coverage improvement targets;
the value range of the coverage improvement target corresponding to each coverage improvement level has no overlapping, and a proportional relationship of a length of a value range of the coverage improvement target corresponding to each coverage improvement level is configured by a system or sent by the first node through the downlink channel to the second node, the value ranges of all the coverage improvement targets which are put together are the same as the range from the minimum value of coverage improvement targets to the maximum value of coverage improvement targets,the value range of the coverage improvement target corresponding to each coverage improvement level has no overlapping, the proportional relationship of the length of the value range of the coverage improvement target corresponding to each coverage improvement level is configured by the system or sent by the first node through the downlink channel to the second node, and the value ranges of all the coverage improvement targets which are put together are less than the value range from the minimum value of coverage improvement targets to the maximum value of coverage improvement targets.
