Embodiment 1

[0040] figure 1 is a flowchart illustrating a method performed by a user equipment according to Embodiment 1 of the present invention.

[0041] Embodiment 1 provides an RACH reporting manner including enhanced coverage level information.

[0042] Such as figure 1 As shown, in step 101, a UE receives a RACH report request from a base station.

[0043] When receiving the RACH report request, in step 103, the UE reports the RACH report to the base station. At this time, the UE sets the content of the RACH report (ie, the rach-report information element) according to the following:

[0044] Setting the first information element (such as numberofpreamblesent) is used to indicate the number of random access preambles sent by the MAC layer in the last (recently) successfully completed random access process;

[0045] Set the value of the corresponding field in the second information element to "TURE" or "1", if the random access for at least one transmission for each enhanced cove...

Embodiment 2

[0051] figure 2 is a flowchart illustrating a method performed by a user equipment according to Embodiment 2 of the present invention.

[0052] Embodiment 2 provides another RACH reporting manner including enhanced coverage level information.

[0053] Such as figure 2 As shown, in step 201, a UE receives a RACH report request from a base station.

[0054] When receiving the RACH report request, in step 203, the UE reports the RACH report to the base station. At this time, the UE sets the content of the RACH report (ie, the rach-report information element) according to the following:

[0055] Setting the first information element (such as numberofpreamblesent) is used to indicate the number of random access preambles sent by the MAC layer in the last (recently) successfully completed random access process;

[0056] Set the value in the third information element to "TURE" or "1", if contention was detected or described as contention resolution for at least one sent random ac...

Embodiment 3

[0063] image 3 is a flowchart illustrating a method performed by a user equipment according to Embodiment 3 of the present invention.

[0064] Embodiment 3 provides yet another RACH reporting manner including enhanced coverage level information.

[0065] Such as image 3 As shown, in step 301, a UE receives a RACH report request from a base station.

[0066] When receiving the RACH report request, in step 303, the UE reports the RACH report to the base station. At this time, the UE sets the content of the RACH report (ie, the rach-report information element) according to the following:

[0067] Setting the first information element (such as numberofpreamblesent) is used to indicate the number of random access preambles sent by the MAC layer in the last (recently) successfully completed random access process;

[0068] Set the value in the third information element to "TURE" or "1", if contention was detected or described as contention resolution for at least one sent rando...

Abstract

The invention provides a method executed by user equipment. The method comprises the following steps: receiving a random access channel RACH report request from a base station; and when an RACH reportrequest from the base station is received, the user equipment reports an RACH report to the base station, the RACH report showing RACH performance of the user equipment for an enhanced coverage leveland / or early data transmission (EDT).

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and more specifically, the present invention relates to a method executed by user equipment and corresponding user equipment. Background technique [0002] In a wireless network, network optimization can achieve the purpose of optimizing network performance. Generally, data collection and data analysis are carried out on the existing deployed and operating networks to find out the reasons that affect the network quality, and to improve network performance by modifying the configured network parameters, adjusting the network structure and deployed equipment, etc. For Self-configuration and Self-Optimization Network (Self-configuration and Self-Optimization Network) refers to the process of automatically adjusting the network based on user equipment and / or base station measurements / performance measurements. The network side can configure the UE to perform SON measurement. T...
