Description

A method, device and storage medium for reporting and receiving information

technical field

The present invention relates to the technical field of wireless communication, in particular to an information reporting and receiving method, device and storage medium.

Background technique

With the rapid development of wireless communication technology, the Internet of Things (IoT) technology has emerged as the times require. Among them, machine-to-machine (M2M) is an important direction of IoT development, and M2M devices are mostly relatively small , Battery-powered systems, such as smart meter reading systems, need to periodically monitor and report the usage of water, electricity, and gas.

For NB-IOT terminals and bandwidth-limited (BL) terminals, the concept of Coverage Enhancement Level (CE Level, CoverageEnhancement Level) is introduced. CE Level is divided into three levels from 0 to 2, corresponding to the signal attenuation of 144dB, 154dB, and 164dB respectively.

The base station will configure corresponding NPRACH (Narrowband Physical Random Access Channel, Narrowband Physical Random Access Channel) resources for each CE Level. The terminal will select corresponding PRACH resources and PRACH retransmission times according to its CE Level. When the random access procedure fails due to the Preamble (preamble) transmission phase, the NB-IoT terminal will re-perform the random access procedure on the NPRACH resources of a higher CE Level until all NPRACH resources of the CE Level are tried.

However, for NB-IoT terminals that successfully enter the RACH (Random Access Channel, Random Access Channel) MSg3 transmission stage in the Preamble stage, when the random access process fails, the NPRACH resources with the same CE Level will be reserved and restarted. Perform random access retries. The premise of this design is to assume that NB-IoT can enter the MSg3 (Message3, information 3) stage, which means that the CE Level of the NB-IoT terminal is selected properly, and the Preamble transmission can be successfully received by the base station.

Since the wireless network environment is constantly changing, it may not be possible for the NB-IOT terminal to use the NPRACH resource corresponding to the CE Level of the last random access attempt to perform random access during the Preamble transmission phase. If the settings are inappropriate, unnecessary preamble retransmissions will be caused, which will cause interference to the network and increase the delay for NB-IOT terminals to access the network.

Detailed ways

In order to reduce network interference and reduce the time delay for Internet of Things terminals or terminals with limited bandwidth to access the network, embodiments of the present invention provide an information reporting and receiving method, device, and storage medium.

The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention, and in the absence of conflict, the present invention The embodiments and the features in the embodiments can be combined with each other.

The terminal random access process is as follows: the base station broadcasts the RSRP threshold corresponding to each CE Level on the BCCH (Broadcast Control Channel, broadcast control channel), as well as the RACH resource and configuration information corresponding to each CE Level; the terminal measures the current serving cell RSRP (Reference Signal Received Power), and compare it with the CE Level threshold received on BCCH to determine the current coverage enhancement level corresponding to itself. According to the determined coverage enhancement level, use the corresponding PRACH resource parameters to initiate a random access procedure. When the random access procedure fails due to the Preamble (preamble) transmission stage, the terminal will select the NPRACH (Narrowband Physical Random Access Channel) resource corresponding to a higher CE Level to perform the random access procedure again until the trial is completed up to all NPRACH resources corresponding to the CE Level. If wireless network parameters such as the CE Level threshold and the maximum number of preamble retransmissions are not set properly, preamble retransmissions will be caused, which will cause interference to the network and increase the delay for terminals to access the network. Therefore, in the embodiment of the present invention, the relevant information in the random access process is reported by the terminal to assist the network side in setting more reasonable wireless network parameters such as the CE level threshold and the maximum number of preamble retransmissions. Specifically, during the random access process according to the CE level indicated by the network or the CE level selected by the terminal, the terminal records the information in the random access process, and selects an appropriate time to report it to the base station, and the base station reports it to the network management Device or server to optimize wireless network parameters.

As shown in FIG. 1, it is a schematic diagram of the implementation flow of the information reporting method provided by the embodiment of the present invention, which may include the following steps:

S11. Initiate a random access procedure by using the physical random access channel resource parameters corresponding to the initial coverage enhancement level.

Among them, before sending the first Preamble, the terminal measures the RSRP of the current serving cell, compares the RSRP with the CE Level threshold received from BCCH, and determines the initial coverage level according to the comparison result; or the terminal obtains the initial coverage enhancement from the signaling sent by the base station Level, where the signaling sent by the base station may include MAC (Media Access Control) signaling, RRC (Radio Resource Control) signaling or PDCCH order (for example, the base station has data to be sent to the terminal, when the terminal UL link lost is detected, Initiate PDCCH order) and so on.

During specific implementation, before initiating the random access procedure, the terminal first reads the BCCH to obtain available RACH (random access channel) resources, and initiates the random access procedure according to the acquired RACH (random access channel) resources.

In this step, the terminal selects a preamble from the available PRACH resource parameters corresponding to the initial coverage enhancement level, and initiates a random access procedure according to the maximum number of retransmissions of each preamble and the number of preamble retransmissions configured by the base station for the initial coverage level.

S12. When the random access response is received or it is judged that the current random access fails, record the log information of the current random access channel.

(6) Coverage enhancement level used for random access message 3 (MSg3) transmission;

That is, when the last preamble sent by the terminal is detected by the base station, the coverage enhancement level corresponding to the PRACH resource used.

(7) The resource number used for PRACH (Physical Random Access Channel) resource selection;

The resource number may be randomly selected by the terminal itself, or may be obtained according to a PDCCH (Physical Downlink Control Channel, physical downlink control channel) order from the base station.

(8) The carrier number used for MSg3 transmission;

The carrier number may be the carrier number of the anchor carrier, or the carrier number of the non-anchor carrier.

(9) The number of retransmissions of the Preamble when the Preamble (preamble) response is received;

That is, when the Preamble finally received the response, the Preamble was retransmitted several times.

(10) GPS (Global Positioning System) geographic location information;

The geographic location information may be geographic location information of the terminal.

(11) Timestamp information.

The terminal records one or more items of the above information and stores them locally.
