Embodiment 1

[0075] In this embodiment, the length of the reporting cycle is an integer multiple of the length of the statistical cycle, and the UE reports multiple groups of statistical results at one time. The specific implementation is as follows:

[0076] 1. When configuring RSSI measurement, in addition to the existing measurement parameters, the eNB configures the statistical cycle for the UE; the length of the reporting cycle is an integer multiple of the length of the statistical cycle;

[0077] 2. The UE performs statistics on the average of the RSSI measurement value and the percentage above the threshold based on each statistical cycle;

[0078] 3. When the reporting period ends, the UE reports a measurement result, and in this report, the UE reports information carrying the measurement results of each statistical period in this reporting period.

Embodiment 2

[0083] In this embodiment, the length of the reporting cycle is longer than the length of the statistical cycle, and the UE only reports the last group of statistical results. In specific implementation:

[0084] 1. When configuring RSSI measurement, in addition to the existing measurement parameters, the eNB configures the statistical cycle for the UE; the length of the reporting cycle is greater than the length of the statistical cycle;

[0085] 2. The UE takes the end time of a reporting cycle as the end point, determines the starting position of the statistical time according to the length of the statistical cycle, and performs statistics on the average and percentage higher than the threshold of the RSSI measurement value in the statistical cycle;

[0086] 3. At the end of the reporting period, the UE reports a measurement result, and in this report, the UE reports information carrying the measurement results of the corresponding statistical period in this reporting perio...

Abstract

The invention discloses a method for indicating and reporting received signal strength indication and a device thereof. The method comprises the steps that statistics of the statistical period length of the received signal strength indication (RSSI) performed by user equipment (UE) is determined at a base station side and the period length is reported; and the UE is indicated to perform statistics according to the statistical period length and perform reporting according to the reported period length. The statistical period length of the RSSI indicated by the base station is received at the UE side and the period length is reported; averaging is performed on the RSSI measurement value based on the statistical period length and / or statistics of the percentage that the RSSI measurement value is higher than the threshold is performed; and the average value of the RSSI measurement value after averaging and / or the statistical value of the percentage that the RSSI measurement value is higher than the threshold in the statistical period is reported according to the reported period length. The reporting overhead and the measurement accuracy can be balanced by the method and the device.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method and device for indicating and reporting received signal strength indications. Background technique [0002] With the continuous growth of mobile data traffic, spectrum resources are becoming more and more tight, and only using authorized spectrum resources for network deployment and service transmission may not be able to meet the traffic demand. Therefore, the Long Term Evolution (LTE, Long Term Evolution) system can be considered in Deploy transmission on unlicensed spectrum resources to improve user experience and expand coverage. When LTE is deployed in an unlicensed spectrum, its unlicensed carrier needs to be used in conjunction with a licensed carrier. Therefore, the related technology is also called LAA (Licensed Assisted Access, licensed carrier assisted access). [0003] 1) Introduction to the principle of LBT (listen Before Talk) on unlicensed ...
