Description

Communication method, communication device, and storage medium technical field

The present disclosure relates to the field of communication technologies, and in particular, to a communication method, a communication device, and a storage medium.

Background technique

In the unlicensed spectrum (New Radio-Unlicensed, NR-U), the transmitter generally needs to perform clear channel assessment (CCA) before sending data. If the interference level in the channel is estimated to be lower than the detection threshold (the detection threshold is specified by the communication protocol) according to the CCA detection result, it is determined that the channel is idle, and the transmitter can occupy the channel to send data. The maximum channel occupy time (MCOT) of the channel occupied by the transmitter is specified by the protocol or configured/instructed by the base station. If the interference level in the channel is estimated to be higher than the detection threshold according to the CCA detection result, the transmitter determines that the channel is busy, and the transmitter cannot occupy the channel to send data. The above process of performing channel access and sending data may be referred to as using the channel access mechanism of listen before talk (LBT) to send data.

In the unlicensed spectrum in the high frequency range, due to the large attenuation of the high frequency channel, even if the distance between the transmitters is relatively close, the mutual interference between them may be relatively small, so the unlicensed spectrum with less serious interference can be used. Adopt the channel access mechanism of no-LBT. That is, the transmitting end may not need to perform LBT before sending data, but directly send data.

However, how to apply the channel access mechanism of no-LBT and the channel access mechanism of LBT to effectively avoid interference and improve transmission efficiency is a technical problem that needs to be solved urgently.

The embodiments of the present disclosure do not limit the number of network devices and the number of terminals included in the wireless communication system.

It can be further understood that the wireless communication system according to the embodiment of the present disclosure is a network that provides a wireless communication function. Wireless communication systems can use different communication technologies, such as code division multiple access (CDMA), wideband code division multiple access (WCDMA), time division multiple access (TDMA) , frequency division multiple access (frequency division multiple access, FDMA), orthogonal frequency division multiple access (orthogonal frequency-division multiple access, OFDMA), single carrier frequency division multiple access (single Carrier FDMA, SC-FDMA), carrier sense Carrier Sense Multiple Access with Collision Avoidance. According to the capacity, speed, delay and other factors of different networks, the network can be divided into 2G (English: generation) network, 3G network, 4G network or future evolution network, such as 5G network, 5G network can also be called a new wireless network ( New Radio, NR). For convenience of description, the present disclosure will sometimes refer to a wireless communication network simply as a network.

Further, the network devices involved in the present disclosure may also be referred to as radio access network devices. The wireless access network device may be: a base station, an evolved node B (evolved node B, base station), a home base station, an access point (AP) in a wireless fidelity (wireless fidelity, WIFI) system, a wireless relay A node, a wireless backhaul node, a transmission point (TP) or a transmission and reception point (TRP), etc., can also be a gNB in an NR system, or can also be a component or part of a device that constitutes a base station Wait. When it is a vehicle-to-everything (V2X) communication system, the network device may also be an in-vehicle device.

It should be understood that the embodiments of the present disclosure do not limit the specific technology and specific device form adopted by the terminal.

In the related art, before the terminal and the network device send information, the transmitter (network device or terminal) as the information sending end needs to use a corresponding channel access mechanism to access the channel and then send the information. There are various channel access mechanisms. For example, the LBT channel access mechanism can be used to perform CCA on the unlicensed spectrum, and the transmitter sends information after the CCA is successful, or the no-LBT channel can be used on the unlicensed spectrum. The access mechanism directly accesses the channel to send information.

Since the unlicensed spectrum supports multiple channel access mechanisms, different channel access mechanisms have different advantages. For example, the channel access mechanism of LBT can effectively avoid interference, and the channel access mechanism of no-LBT can improve the efficiency of communication transmission. However, with the development of communication technology, how to effectively avoid interference and improve transmission efficiency is a hot issue that needs to be studied.

An embodiment of the present disclosure provides a communication method, in which a transmitter determines a channel access mechanism based on actual channel conditions. For example, a condition for performing channel access mechanism switching is preset, and when the channel detection result satisfies the condition, a channel access mechanism is performed. switch to effectively avoid interference and improve transmission efficiency.

FIG. 2 is a flow chart of a communication method according to an exemplary embodiment. As shown in FIG. 2 , the communication method is used in a transmitter, which may be a terminal or a network device, and includes the following steps.

In step S11, the currently adopted first channel access mechanism is determined.

In the embodiment of the present disclosure, the first channel access mechanism currently adopted by the transmitting end may be an LBT channel access mechanism or a no-LBT channel access mechanism.

In an implementation manner, in the embodiment of the present disclosure, the transmitting end may perform channel detection, and determine whether to perform switching of the channel access mechanism based on the channel detection result. For example, channel energy detection, interference value detection, etc. are performed.

Wherein, in the embodiment of the present disclosure, a condition for performing channel access mechanism switching may be preset, which is hereinafter referred to as the first condition.

The transmitting end may determine whether to switch the channel access mechanism based on the channel detection result and the first condition.

In step S12, in response to the channel detection result satisfying the first condition, switching from the first channel access mechanism to the second channel access mechanism.

In the embodiment of the present disclosure, if the channel detection result satisfies the first condition, the transmitter switches the channel access mechanism from the first channel access mechanism to the second channel access mechanism. Wherein, the second channel access mechanism is different from the first channel access mechanism.

In one embodiment, the first channel access mechanism is an LBT channel access mechanism, and the second channel access mechanism is a no-LBT channel access mechanism. In another embodiment, the first channel access mechanism is a no-LBT channel access mechanism, and the second channel access mechanism is an LBT channel access mechanism.

In the embodiment of the present disclosure, when the channel detection result satisfies the first condition, the currently adopted first channel access mechanism is switched to the second channel access mechanism, and the channel access mechanism on the unlicensed spectrum is switched to effectively avoid interference and improve transmission efficiency.

In the embodiments of the present disclosure, the communication methods involved in the foregoing embodiments are described below in combination with practical applications.

In an example, the first channel access mechanism in the embodiment of the present disclosure may be a default channel access mechanism.

In the embodiment of the present disclosure, the channel access mechanism set by default is stipulated by a protocol or configured by a network device. For example, the protocol stipulates that the default channel access mechanism used by the transmitting end is the LBT channel access mechanism, or may also be the no-LBT channel access mechanism. For another example, the default channel access mechanism configured by the network device (eg, the base station) for the transmitting end is the LBT channel access mechanism, or may also be the no-LBT channel access mechanism.

In another example, the first channel access mechanism may also be a channel access mechanism currently used by the transmitting end after changing the default channel access mechanism. For example, the first channel access mechanism may be the channel access mechanism after the channel access mechanism is switched by the transmitting end, and then based on the channel access mechanism after the channel access mechanism switch, it continues to detect and determine whether to continue the channel access. mechanism switching.

In the embodiment of the present disclosure, the first channel access mechanism may be an LBT channel access mechanism or a no-LBT channel access mechanism, and the second channel access mechanism may be a no-LBT channel access mechanism or an LBT channel access mechanism.

In an example of the present disclosure, the first channel access mechanism is an LBT channel access mechanism, and the second channel access mechanism is a no-LBT channel access mechanism as an example for description.

In one embodiment, the transmitter determines that the currently used first channel access mechanism is the LBT channel access mechanism, and can use the traditional method to perform energy detection before LBT channel access. After that, it is determined that the channel interference is low, and it can be determined that the channel access mechanism needs to be switched, for example, switching to the no-LBT channel access mechanism, so as to improve the communication transmission efficiency under the condition of low interference.

Wherein, in the embodiment of the present disclosure, the first channel access mechanism is the LBT channel access mechanism, and the second channel access mechanism is the no-LBT channel access mechanism, and the first condition may be set to determine the interference based on the energy before the LBT channel access. The relatively low energy detection threshold is hereinafter referred to as the first energy detection threshold. The energy before the access of the LBT channel is lower than the first energy detection threshold, which can be understood as the fact that the channel interference is low, and the impact on the communication transmission is within an acceptable range.

In one embodiment, the transmitting end performs energy detection before the access of the first number of LBT channels, and if the mean value of the energy detection results before the access of the first number of LBT channels is less than or equal to the first energy detection threshold, the channel is determined. The interference situation is low, and the no-LBT channel access mechanism can be switched at this time. It can also be understood that when the transmitter uses the LBT channel access mechanism, it can be determined whether to switch to no-LBT by comparing the average value of the energy detection of one or more (first number) LBTs with the first energy detection threshold value. . When the interference is found to be low after a period of channel measurement, it switches to no-LBT autonomously.

Wherein, in this embodiment of the present disclosure, the first quantity for performing energy detection before LBT channel access may be a protocol agreement, or may be configured by a network device.

The first energy detection threshold value in the embodiment of the present disclosure may be a protocol agreement, or may be configured by a network device.

Further, in the embodiment of the present disclosure, the mean value of the energy detection results of the first number of LBT channels before access may be a linear mean value, or may be a weighted mean value, a geometric mean value, a harmonic mean value, etc. of different samples determined by using different mean value calculation methods. .

In another example of the present disclosure, the first channel access mechanism is a no-LBT channel access mechanism, and the second channel access mechanism is an LBT channel access mechanism as an example for description.

In an embodiment, when the transmitting end determines that the currently used first channel access mechanism is the no-LBT channel access mechanism, channel energy detection can be performed. In the case of LBT monitoring, the channel access mechanism can be switched to the LBT channel access mechanism.

In an embodiment, the first channel access mechanism is the no-LBT channel access mechanism, and the second channel access mechanism is the LBT channel access mechanism, the first condition may be set to determine the interference situation based on the channel energy detection result. The relatively low energy detection threshold value is hereinafter referred to as the second energy detection threshold value. The channel energy detection result is greater than the second energy detection threshold, indicating that the channel interference is relatively large, and LBT monitoring is required to reduce the influence of interference on communication performance.

In one embodiment, when the transmitter uses the no-LBT channel access mechanism for channel access, the transmitter performs periodic energy detection with a specified cycle duration (hereinafter referred to as the first cycle duration). Or the channel energy detection result detected in multiple cycles (hereinafter referred to as the second number of cycles) exceeds the second energy detection threshold, it can be determined that the channel interference is relatively large, and the channel is switched to the LBT channel access mechanism to perform LBT monitoring. Reduce the impact of interference on communication performance. That is, the transmitting end performs periodic channel energy detection with the first period duration. The channel detection result satisfies the first condition, including: the second number of periodic channel energy detection results is greater than the second energy detection threshold.

Wherein, in the case where the no-LBT channel access mechanism is adopted in the embodiment of the present disclosure, the second quantity of periodic energy detection performed by the transmitting end may be stipulated in the protocol, or may be configured by the network device.

Further, in the embodiment of the present disclosure, when the no-LBT channel access mechanism is adopted, the first period duration of the periodic energy detection performed by the transmitting end may be specified in the protocol or configured by the network device.

Further, in the embodiment of the present disclosure, the second energy detection threshold value may be stipulated in a protocol, or may be configured by a network device.

The communication method provided by the embodiment of the present disclosure can switch the channel access mechanism, for example, switch between the LBT channel access mechanism and the no-LBT channel access mechanism, and realize the channel access mechanism switching on the unlicensed spectrum, In order to effectively avoid interference and improve transmission efficiency.

The communication method provided by the embodiment of the present disclosure can be applied to the process of channel access by the transmitter in the process of information sending by the network device and the terminal.
