Embodiment 1

[0224] Embodiment 1: In this embodiment, measurement configuration information is configured through dedicated signaling, and event-triggered reporting is used. The specific process is as follows:

[0225] 1. The eNB configures the UE to report the LBT result through RRC dedicated signaling, where the measurement configuration information in the RRC dedicated signaling is as follows:

[0226] a) Frequency point or frequency point list of the cell to be measured: such as F1, F2;

[0227] b) The preset measurement time period D;

[0228] c) The reporting condition is event-triggered reporting; the events that trigger reporting are as follows:

[0229] Trigger event E1: the statistical LBT failure probability is greater than or equal to the first upper limit; and / or

[0230] Trigger event E2: the total number of counted LBTs is greater than or equal to the first number threshold.

[0231] Preset parameters: the first upper limit and the first threshold.

[0232] d) Report con...

Embodiment 2

[0243] Embodiment 2: In this embodiment, the measurement configuration information is configured through dedicated signaling, and a periodic triggering method is adopted. The specific process is as follows:

[0244] 1: The eNB configures the UE to report the LBT result through RRC dedicated signaling, where the measurement configuration information in the RRC dedicated signaling is as follows:

[0245] a) The identification or identification list of the cell to be measured: such as Cell ID1, Cell ID2;

[0246] b) The LBT priority that needs to be counted;

[0247] c) Reporting condition: periodic trigger;

[0248] Trigger period T;

[0249] Reporting content: the probability of LBT failure of the corresponding frequency point, and / or the number of times of LBT failure / success, etc.

[0250] d) Whether to report auxiliary information: whether to report UE location information while reporting statistical results.

[0251] 2: After receiving the measurement configuration info...

Embodiment 3

[0258] Embodiment 3: In this embodiment, configuration measurement configuration information is configured through a system message (broadcast message), and an event trigger mode is adopted. The specific process is as follows:

[0259] 1: The eNB configures all UEs in a specific cell (that is, the cell to be measured) to report LBT results through the RRC system message. The measurement configuration information in the RRC system message is as follows:

[0260] a) The preset measurement time period D;

[0261] b) Reporting condition: event trigger; where the trigger event is as follows:

[0262] Trigger event E1: the statistical LBT failure probability is greater than or equal to the first upper limit; and / or

[0263] Trigger event E2: the total number of counted LBTs is greater than or equal to the first number threshold.

[0264] Preset parameters: the first upper limit and the first threshold.

[0265] d) Report content: the number of LBT failures and the number of LBT s...

Abstract

The invention discloses a measurement method in an unlicensed spectrum and equipment which are used for solving a problem that the network cannot accurately schedule data transmission of LTE (Long Term Evolution) UE on an unlicensed carrier because the LTE UE needs to share the spectrum in a time division manner with other wireless communication technologies on the unlicensed spectrum. The measurement method comprises the steps that the UE performs LBT on the unlicensed spectrum when determining that uplink transmission needs to be performed and calculates an LBT result; and the UE sends reporting information related with the LBT result calculated by the UE when determining that a reporting condition is met. The UE sends the reporting information related with the LBT result calculated by the UE to network equipment so as to enable the network equipment to determine whether the UE is suitable to work in the corresponding unlicensed spectrum cell or not according to the LBT result calculated by the UE.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a measurement method and equipment in an unlicensed frequency spectrum. Background technique [0002] For mobile operators, licensed spectrum (Licensed Bands) has always been their core assets, the basis for providing high-quality wireless communication services, and will play a pivotal role in the foreseeable future. However, with the vigorous development of the mobile Internet, the contradiction between the outbreak of public demand for high-bandwidth wireless services and the scarcity of spectrum resources has become increasingly acute. Unlicensed spectrum (Unlicensed Bands) still has abundant resources and great development as a supplement to licensed spectrum. space. Taking the 5GHz frequency band as an example, the total number of unlicensed spectrum resources allocated by countries around the world exceeds 500MHz. [0003] Licensed-Assisted Access (LAA for short) i...
