Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to communication methods, communication devices and storage media. Background Technology

[0002] In unlicensed spectrum (New Radio-Unlicensed, NR-U), the transmitter typically performs clear channel assessment (CCA) before sending data. If the interference level in the channel, as assessed by the CCA, is below a detection threshold (defined by the communication protocol), the channel is considered idle, and the transmitter can occupy the channel to send data. The maximum channel occupy time (MCOT) is determined by the protocol or configured / indicated by the base station. If the interference level in the channel, as assessed by the CCA, is above the detection threshold, the transmitter determines the channel is busy and cannot occupy the channel to send data. This process of channel access and data transmission can be referred to as using a listen-before-talk (LBT) channel access mechanism for data transmission.

[0003] In the unlicensed spectrum within the high-frequency range, due to the significant attenuation of high-frequency channels, even if the transmitters are close together, the mutual interference may be relatively small. Therefore, for unlicensed spectrum where interference is not severe, a no-LBT channel access mechanism can be adopted. That is, the transmitter can transmit data directly without performing LBT before transmitting data.

[0004] However, how to apply no-LBT and LBT channel access mechanisms to effectively avoid interference and improve transmission efficiency is a technical problem that urgently needs to be solved. Summary of the Invention

[0033] Figure 5This is a block diagram illustrating a communication apparatus according to an exemplary embodiment. Detailed Implementation

[0034] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0035] The communication method provided in this disclosure can be applied to... Figure 1 The wireless communication system shown. (See attached image) Figure 1 As shown, this wireless communication system includes a terminal and a network device. The terminal and the network device send and receive information through wireless resources.

[0036] Understandable, Figure 1 The wireless communication system shown is for illustrative purposes only. A wireless communication system may also include other network devices, such as core network equipment, wireless relay equipment, and wireless backhaul equipment. Figure 1 Not shown in the diagram. This disclosure does not limit the number of network devices and terminals included in the wireless communication system.

[0037] It is further understood that the wireless communication system of this disclosure is a network providing wireless communication functionality. The wireless communication system can employ 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 (FDMA), orthogonal frequency-division multiple access (OFDMA), single-carrier frequency division multiple access (SC-FDMA), and carrier sense multiple access with collision avoidance. Based on factors such as capacity, speed, and latency, networks can be categorized as 2G networks, 3G networks, 4G networks, or future evolution networks, such as 5G networks. 5G networks can also be referred to as New Radio (NR). For ease of description, this disclosure may sometimes simply refer to the wireless communication network as a network.

[0038] Furthermore, the network device involved in this disclosure can also be referred to as a wireless access network device. This wireless access network device can be: a base station, an evolved Node B (eB) base station, a home base station, an access point (AP) in a Wireless Fidelity (WIFI) system, a wireless relay node, a wireless backhaul node, a transmission point (TP), or a transmission and reception point (TRP), etc. It can also be a gNB in ​​an NR system, or a component or part of a base station. When it is a vehicle-to-everything (V2X) communication system, the network device can also be an in-vehicle device. It should be understood that the specific technologies and device forms used in the embodiments of this disclosure are not limited.

[0039] Furthermore, the terminal involved in this disclosure can also be referred to as a terminal device, user equipment (UE), mobile station (MS), mobile terminal (MT), etc., and is a device that provides voice and / or data connectivity to a user. For example, a terminal can be a handheld device with wireless connectivity, an in-vehicle device, etc. Currently, some examples of terminals include: smartphones (Mobile Phones), pocket personal computers (PPCs), handheld computers, personal digital assistants (PDAs), laptops, tablets, wearable devices, or in-vehicle devices, etc. In addition, when it is a vehicle-to-everything (V2X) communication system, the terminal device can also be an in-vehicle device. It should be understood that the embodiments of this disclosure do not limit the specific technology or specific device form adopted by the terminal.

[0040] In related technologies, before a terminal and network device can transmit information, the transmitting end (network device or terminal) needs to access the channel using an appropriate channel access mechanism before transmitting the information. There are various channel access mechanisms. For example, on unlicensed spectrum, the LBT channel access mechanism can be used for CCA (Continuous Access Compatibility), and the transmitting end transmits information after successful CCA. Alternatively, on unlicensed spectrum, the no-LBT channel access mechanism can be used to directly access the channel and transmit information.

[0041] Because unlicensed spectrum supports multiple channel access mechanisms, each with its own advantages, such as LBT (Locally Access Bypass) effectively avoiding interference and no-LBT (No-LBT) improving communication transmission efficiency, how to effectively avoid interference while simultaneously improving transmission efficiency remains a hot research topic as communication technology advances.

[0042] This disclosure provides a communication method in which the transmitting end determines the channel access mechanism based on actual channel conditions. For example, the conditions for switching the channel access mechanism are preset. When the channel detection result meets the conditions, the channel access mechanism is switched to effectively avoid interference and improve transmission efficiency.

[0043] In this embodiment of the disclosure, for ease of description, the channel access mechanism currently used by the transmitter is referred to as the first channel access mechanism, and the channel access mechanism after the transmitter switches is referred to as the second channel access mechanism.

[0044] Figure 2 This is a flowchart illustrating a communication method according to an exemplary embodiment, such as... Figure 2As shown, the communication method is used in the transmitting end, which can be a terminal or a network device, and includes the following steps.

[0045] In step S11, the first channel access mechanism currently being used is determined.

[0046] In this embodiment of the disclosure, the first channel access mechanism currently used by the transmitter can be either the LBT channel access mechanism or the no-LBT channel access mechanism.

[0047] In one embodiment of this disclosure, the transmitting end can perform channel detection and determine whether to switch the channel access mechanism based on the channel detection results. For example, this may involve channel energy detection or interference value detection.

[0048] In this embodiment of the disclosure, the conditions for switching the channel access mechanism can be preset, which are referred to as the first conditions.

[0049] The transmitter can determine whether to switch the channel access mechanism based on the channel detection results and the first condition.

[0050] In step S12, in response to the channel detection result satisfying the first condition, the system switches from the first channel access mechanism to the second channel access mechanism.

[0051] In this embodiment of the disclosure, if the channel detection result meets the first condition, the transmitter switches the channel access mechanism from the first channel access mechanism to the second channel access mechanism. The second channel access mechanism differs from the first channel access mechanism.

[0052] 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.

[0053] In this embodiment of the disclosure, when the channel detection result meets the first condition, the current first channel access mechanism is switched to the second channel access mechanism to realize the switching of channel access mechanism on the unlicensed spectrum, so as to effectively avoid interference and improve transmission efficiency.

[0054] The communication methods involved in the above embodiments will be described below in conjunction with practical applications.

[0055] In one example, the first channel access mechanism in this embodiment of the present disclosure may be the default channel access mechanism.

[0056] In this embodiment of the disclosure, the default channel access mechanism is determined by the protocol or configured by the network device. For example, the protocol may stipulate that the default channel access mechanism used by the transmitter is the LBT channel access mechanism, or it may be a no-LBT channel access mechanism. As another example, the network device (e.g., a base station) may configure the default channel access mechanism used by the transmitter to be the LBT channel access mechanism, or it may be a no-LBT channel access mechanism.

[0057] In another example, the first channel access mechanism can also be a modified version of the default channel access mechanism and the channel access mechanism currently used by the transmitter. For example, the first channel access mechanism can be the channel access mechanism after the transmitter switches its channel access mechanism, and then, based on this new channel access mechanism, the transmitter continues to detect and determine whether to continue switching the channel access mechanism.

[0058] In this embodiment of the 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.

[0059] In one example disclosed herein, the first channel access mechanism is an LBT channel access mechanism and the second channel access mechanism is a no-LBT channel access mechanism.

[0060] In one implementation, the transmitter determines that the first channel access mechanism currently in use is the LBT channel access mechanism. It can perform LBT channel access pre-access energy detection in a traditional manner. If, after performing a certain number of LBT channel access pre-access energy detections, it is determined that the channel interference is low, it can be determined that the channel access mechanism needs to be switched, for example, to the no-LBT channel access mechanism, so as to improve communication transmission efficiency under low interference conditions.

[0061] In this 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. A first condition can be set as an energy detection threshold value, hereinafter referred to as the first energy detection threshold value, to determine a relatively low interference level based on the energy level before LBT channel access. If the energy level before LBT channel access is lower than this first energy detection threshold value, it can be understood that the channel interference is low, and the impact on communication transmission is within an acceptable range.

[0062] In one implementation, the transmitter performs a first number of LBT channel access pre-access energy checks. If the average of the first number of LBT channel access pre-access energy checks is less than or equal to a first energy detection threshold, then the channel interference is determined to be low, and the transmitter can switch to the no-LBT channel access mechanism. Alternatively, when using the LBT channel access mechanism, the transmitter can determine whether to switch to no-LBT by comparing the average of one or more (the first number) LBT energy checks with the first energy detection threshold. When channel measurements over a period of time indicate low interference, the transmitter autonomously switches to no-LBT.

[0063] In this embodiment of the disclosure, the first number of energy detections performed before LBT channel access can be agreed upon by the protocol or configured by the network device.

[0064] In this embodiment of the present disclosure, the first energy detection threshold value may be agreed upon by a protocol or configured by the network device.

[0065] Furthermore, in this embodiment, the mean value of the energy detection results of the first number of LBT channels before access can be a linear mean, or it can be a mean value determined by different mean calculation methods such as weighted mean, geometric mean, and harmonic mean of different samples.

[0066] In another example of this 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, which will be used as an example for illustration.

[0067] In one implementation, if the transmitter determines that the currently used first channel access mechanism is the no-LBT channel access mechanism, channel energy detection can be performed. If the channel energy detection result indicates that the channel interference is significant and LBT monitoring is required, the channel access mechanism can be switched to the LBT channel access mechanism.

[0068] In one implementation, where the first channel access mechanism is a no-LBT channel access mechanism and the second channel access mechanism is an LBT channel access mechanism, a first condition can be set as an energy detection threshold value with relatively low interference based on the channel energy detection result, hereinafter referred to as the second energy detection threshold value. If the channel energy detection result is greater than the second energy detection threshold value, it indicates that the channel interference is relatively large, and LBT monitoring is required to reduce the impact of interference on communication performance.

[0069] In one implementation, when the transmitter uses a no-LBT channel access mechanism for channel access, the transmitter performs periodic energy detection for a specified period duration (hereinafter referred to as the first period duration). If the channel energy detection results within one or more periods (hereinafter referred to as the second number of periods) exceed the second energy detection threshold, it can be determined that the channel interference is significant, and the transmitter switches to the LBT channel access mechanism for LBT monitoring to reduce the impact of interference on communication performance. That is, the transmitter performs periodic channel energy detection for the first period duration. The channel detection results satisfy a first condition, including: the second number of periodic channel energy detection results are greater than the second energy detection threshold.

[0070] In this embodiment of the present disclosure, when using the no-LBT channel access mechanism, the second number of periodic energy detections performed by the transmitter can be agreed upon by the protocol or configured by the network device.

[0071] Furthermore, in this embodiment of the present disclosure, when using the no-LBT channel access mechanism, the duration of the first period of the periodic energy detection performed by the transmitter can be agreed upon by the protocol or configured by the network device.

[0072] Furthermore, in this embodiment of the present disclosure, the second energy detection threshold can be agreed upon by the protocol or configured by the network device.

[0073] The communication method provided in this disclosure can switch the channel access mechanism, such as switching between the LBT channel access mechanism and the no-LBT channel access mechanism, to achieve channel access mechanism switching on unlicensed spectrum, so as to effectively avoid interference and improve transmission efficiency.

[0074] The communication method provided in this disclosure can be applied to the process of the transmitting end accessing the channel during the information transmission process of network devices and terminals.

[0075] Based on the same concept, embodiments of this disclosure also provide a communication device.

[0076] It is understood that the communication device provided in this disclosure includes hardware structures and / or software modules corresponding to each function in order to achieve the above-mentioned functions. In conjunction with the units and algorithm steps of the various examples disclosed in this disclosure, this disclosure can be implemented in hardware or a combination of hardware and computer software. Whether a function is executed by hardware or by computer software driving hardware depends on the specific application and design constraints of the technical solution. Those skilled in the art can use different methods to implement the described functions for each specific application, but such implementation should not be considered beyond the scope of the technical solutions of this disclosure.

[0079] In one implementation, the first channel access mechanism is the Listen Before Talk (LBT) channel access mechanism, and the second channel access mechanism is the No-LBT channel access mechanism.

[0081] In one implementation, the first channel access mechanism is a no-LBT channel access mechanism without listening first and speaking later, and the second channel access mechanism is a LBT channel access mechanism with listening first and speaking later.

[0082] In one embodiment, the processing unit 101 is further configured to perform periodic channel energy detection for a first period duration. The channel detection result satisfies a first condition, including: a second number of periodic channel energy detection results being greater than a second energy detection threshold.

[0083] In one implementation, the first channel access mechanism is the default channel access mechanism.
