APPARATUS AND METHOD FOR ADJUSTING RANDOM ACCESS POWER CONTROL PARAMETER
First Claim
1. A method for adjusting a random access power control parameter, comprising:
- obtaining, by a base station, random access information reported by multiple user equipment (UEs), wherein the random access information comprises a contention conflict indication and a number of times of sending a preamble;
collecting, by the base station, statistics on the random access information including contention conflict indication indicating a non-contention conflict;
determining, by the base station, a first random access probability according to the random access information including contention conflict indication indicating a non-contention conflict, wherein the first random access probability represents a probability of random access in which the number of times of sending a preamble is 1; and
adjusting, by the base station, a first random access power control parameter according to the first random access probability, wherein the first random access power control parameter is a preamble-initial-received-target-power.

Abstract
The embodiment of the present invention provides an apparatus and a method for adjusting a control parameter. The method in the embodiment of the present invention includes: obtaining, by a base station, random access information reported by multiple user equipment (UEs), where the random access information includes a contention conflict indication and a number of times of sending a preamble; collecting, by the base station, statistics on the random access information including contention conflict indication indicating a non-contention conflict; determining, by the base station, a first random access probability according to the random access information including contention conflict indication indicating a non-contention conflict; and adjusting, by the base station, a first random access power control parameter according to the first random access probability, where the first random access power control parameter is a preamble-initial-received-target-power.

11. An apparatus, comprising:
-
a transceiver, configured to obtain random access information reported by multiple user equipment (UEs), wherein the random access information comprises a contention conflict indication and a number of times of sending a preamble; a memory, configured to store the random access information reported by the multiple UEs; and a processor, configured to;
collect statistics on the random access information including contention conflict indication indicating a non-contention conflict;
determine a first random access probability according to the random access information including contention conflict indication indicating a non-contention conflict, wherein the first random access probability represents a probability of random access in which the number of times of sending a preamble is 1; and
adjust a first random access power control parameter according to the first random access probability, wherein the first random access power control parameter is a preamble-initial-received-target-power. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
