Communication optimization method and apparatus, communication device, and storage medium Cross-reference to related applications

[0001] This application is based on Chinese Patent Application No. 2024110570240 entitled "Communication optimization method and apparatus, communication device, and storage medium" filed on August 2, 2024, which is incorporated by reference in its entirety into this application. TECHNICAL FIELD

[0002] The present application relates to the technical field of wireless communication, and in particular to a communication optimization method and apparatus, a communication device, and a storage medium. BACKGROUND

[0003] In a wireless communication system, a more critical task is to adjust the processing mode of data transmission and reception and select the communication parameters involved in the data transmission and reception process according to the state of the wireless channel, so as to better ensure the efficiency of data transmission. With the introduction of sensing technology, the wireless communication system can combine sensing technology to determine the wireless channel state of the user equipment, thereby optimizing the communication quality of the user equipment.

[0004] For example, in a possible scenario, there are obstructions between the base station and the user equipment, which can be houses, cars, etc. If these obstructions are located on the LOS (Line-of-Sight path) between the base station and the user equipment, it will cause the communication quality to decline, and by combining sensing technology, the wireless communication system can construct a virtual "LOS path" for the user equipment according to the sensing information (location of obstacles, etc.) and positioning information (location of user equipment, etc.), so that the user equipment can communicate based on the virtual "LOS path", thereby optimizing the communication quality of the user equipment.

[0054] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application is further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.

[0055] Currently, sensing technology is being introduced into wireless communication systems, through which the wireless communication systems can obtain multi-dimensional and multi-level sensing information of target objects, environment, substances, etc., thereby serving industrial upgrading, social governance and smart life, etc. Referring to FIG. 1, in the current wireless communication system, the sensing modes mainly include the following:

[0056] 1. Base station self-sending and self-receiving. The base station (base station A) sends a sensing signal, and after the sensing signal is reflected by the measured object, the base station (base station A) receives the reflected wave.

[0057] 2. One base station sending and another base station receiving. The base station A sends a sensing signal, and after the sensing signal is reflected by the measured object, the base station B receives the reflected wave.

[0058] 3. User equipment sending and base station receiving. The user equipment (terminal A) sends a sensing signal, and after the sensing signal is reflected by the measured object, the base station (base station A) receives the reflected wave.

[0059] 4. Base station sending and user equipment receiving. The base station (base station B) sends a sensing signal, and after the sensing signal is reflected by the measured object, the user equipment (terminal B) receives the reflected wave.

[0060] 5. User equipment self-sending and self-receiving. The user equipment (terminal A) sends a sensing signal, and after the sensing signal is reflected by the measured object, the user equipment (terminal A) receives the reflected wave.

[0061] 6. One user equipment sending and another user equipment receiving. Terminal A sends a sensing signal, and after the sensing signal is reflected by the measured object, terminal B receives the reflected wave.

[0062] The above sensing modes can be classified into two types of sensing technologies:

[0063] 1. Single-base sensing technology: Single-base sensing technology refers to that the transmitter and the receiver of the sensing system are located at the same position, the sensing signal transmitted by the transmitter is reflected by the target to be sensed, and then is received by the receiver at the same position as the transmitter and is subjected to sensing processing. For example, mode 1 and mode 5 above.

[0064] 2. Double-base sensing technology: Double-base sensing technology refers to that the antennas at different positions in space perform transmission and reception. For example, other modes than mode 1 and mode 5 above.

[0065] With the introduction of sensing technology, communication and sensing integration (which can also be referred to as communication-sensing fusion) has become an important research direction at present. In practical applications, there are many application scenarios of communication-sensing fusion, and typical scenarios can include indoor communication-sensing fusion scenarios, outdoor communication-sensing fusion scenarios, and the like.

[0066] In practical applications, a wireless communication system can also determine the wireless channel state of a user equipment in combination with sensing technology, so as to optimize the communication quality of the user equipment.

[0067] For example, refer to FIG. 2. In a possible scenario, there are obstructions between the base station and the user equipment, which can be houses, vehicles, and the like. If these obstructions are located on the LOS (Line-of-Sight path) between the base station and the user equipment (as shown by the dashed line in FIG. 2), the communication quality will be degraded. In combination with sensing technology, the wireless communication system can construct a virtual “LOS path” (as shown by the solid line in FIG. 2) for the user equipment according to sensing information (the position of the obstacle, etc.) and positioning information (the position of the user equipment, etc.), so that the user equipment can communicate based on the virtual “LOS path”, thereby optimizing the communication quality of the user equipment.

[0068] However, in the current communication quality optimization scenario, the wireless communication system needs to know the identity of the user equipment, so as to determine the position of the user equipment, and thus to perform targeted optimization of the communication quality of the user equipment. However, in many cases, the sensing technology cannot identify the identity of the user equipment, and in this case, it is impossible to perform targeted communication quality optimization processing on the user equipment.

[0069] Based on this, the application provides a communication optimization method, in which a first communication device can acquire a target geographic area, wherein the target geographic area is determined based on obstacle awareness information, and then, communication coverage in the target geographic area is optimized. Since the communication coverage in the target geographic area is optimized, user equipment located in the target geographic area can all obtain optimized communication quality. In other words, the communication optimization method provided by the application does not need to perform targeted communication quality optimization on user equipment by identifying the identity of the user equipment, but performs universal and non-targeted communication quality optimization on user equipment in the target geographic area, thereby achieving the effect of optimizing the communication quality of user equipment without identifying the identity of the user equipment.

[0070] It should be noted that the beneficial effects or technical problems solved by the embodiments of the application are not limited to this, but can also be other implicit or related problems. For details, please refer to the description of the following embodiments.

In optional embodiments of the application, the first communication device can be user equipment, or the first communication device can be a network side device. In optional embodiments of the application, the network side device can be, for example, an access network device.

[0072] The user equipment involved in the embodiments of the present application can be a wireless terminal, which can be a device providing voice and / or other service data connectivity to a user, or a handheld device with wireless connection function, or other processing device connected to a wireless modem. The wireless terminal can be a USB storage device, other personal computer memory device and dongle, and can also communicate with one or more core networks (CN) through a radio access network (RAN). The wireless terminal can be a mobile terminal, such as a mobile phone (or called "cellular" phone) and a computer with mobile terminal device, for example, a portable, pocket, handheld, built-in or vehicle-mounted mobile device, which exchanges voice and / or data with a radio access network. For example, the wireless terminal can be a personal communication service (PCS) phone, a cordless phone, a session initiated protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a personal computer, a tablet computer, a machine type communication (MTC) terminal device, etc. The wireless terminal can also be called a system, a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, a user device, a wireless access device and a router / modem satisfying the limitation of the definition, etc., which are not limited in the embodiments of the present application.

[0073] The access network device involved in the present application can be a base station in an access network. Among them, the base station involved in the embodiments of the present application can be a base station (Base Transceiver Station, BTS) in Global System of Mobile communication (GSM) or Code Division Multiple Access (CDMA), or a base station (NodeB, NB) in Wideband Code Division Multiple Access (WCDMA), or an evolved base station (eNB or eNodeB) in LTE, or a base station in a 5G network, or a base station in a future communication system, which is not limited here.

[0074] In addition, it should be noted that the communication optimization method provided by the embodiments of the present application can be applied to various different communication scenarios, and the following embodiments of the present application will provide two exemplary applicable communication scenarios:

[0075] 1. The scenario of communication between user equipment and network side.

[0076] In this communication scenario, the user equipment communicates with the access network device through a wireless interface, such as a Uu interface, and the technical solution provided by the embodiments of the present application can optimize the communication quality of the wireless interface.

[0077] Among them, the communication scenario can include a communication scenario with fixed position of the access network device and a communication scenario with unfixed position of the access network device, wherein the position of the access network device does not change in the communication scenario with fixed position of the access network device, and the position of the user equipment can be moved, and in the communication scenario with unfixed position of the access network device, the position of the access network device and the position of the user equipment can be moved, for example, the access network device can be a drone base station, or the access network device can be a satellite base station, etc.

[0078] 2. The scenario of direct communication between user equipment and user equipment.

[0079] In this communication scenario, the user equipment communicates with other user equipment through a direct communication interface (an interface for direct communication between user equipment), and the technical solution provided by the embodiments of the present application can optimize the communication quality of the direct communication interface.

[0080] The technical solutions of the present application and how the technical solutions solve the above technical problems will be described in detail below with specific examples. The following specific examples can be combined with each other, and the same or similar concepts or processes can not be described again in some examples. The embodiments of the present application will be described below with reference to the drawings.

[0081] In one embodiment, as shown in FIG. 3, a communication optimization method is provided, which is described below by taking the first communication device as an example, including the following steps:

[0082] Step 301, the first communication device acquires a target geographic area.

[0083] The target geographic area is determined based on obstacle awareness information, the obstacle awareness information is information obtained by perceiving a target obstacle, the target obstacle can be one or more, and the obstacle awareness information can include position information, volume information, etc. of the target obstacle, which is not limited in the embodiments of the present application.

[0084] The target geographic area can be an area whose communication quality is affected by the target obstacle, for example, the target geographic area can be an area whose channel quality is deteriorated due to the target obstacle, or the target geographic area can be a coverage hole area caused by the target obstacle. In some embodiments, the target geographic area can be an area whose communication quality between the user equipment and the network side is affected by the target obstacle, or an area whose direct communication quality between the user equipment and the user equipment is affected by the target obstacle.

[0085] In optional embodiments of the present application, the target obstacle can be an obstacle between the user equipment and the network side device, and / or the target obstacle can be an obstacle between the user equipment and the user equipment. The obstacle between the user equipment and the network side device can affect the communication quality between the user equipment and the network side, and the obstacle between the user equipment and the user equipment can affect the communication quality of the direct communication between the user equipment and the user equipment.

[0086] In optional embodiments of the present application, the target obstacle can be a moving obstacle, such as a truck, etc., or a fixed obstacle, such as a building, etc.

[0087] In optional embodiments of the present application, the moving obstacle can refer to a relatively moving obstacle. For example, in a communication scenario in which the base station is not fixed, the obstacle moves relative to the base station because the position of the base station changes. In this case, the obstacle that moves relative to the base station is a relatively moving obstacle. For example, the base station can be a drone, and the obstacle can be a building. Because the drone moves, the building moves relative to the drone, and thus the building is a relatively moving obstacle.

[0088] In optional embodiments of the present application, the target obstacle can be a newly appearing obstacle. The newly appearing obstacle can be understood as an obstacle that does not appear in a historical period but appears currently. For example, the newly appearing obstacle can be a temporarily parked truck or a newly built house.

[0089] In optional embodiments of the present application, the first communication device can obtain the target geographic area. For example, the first communication device can obtain the position, size, coordinates, and the like of the target geographic area. The embodiments of the present application do not make specific limitations in this regard.

[0090] In step 302, the first communication device performs optimization processing on the communication coverage in the target geographic area.

[0091] In optional embodiments of the present application, the first communication device can optimize the communication coverage in multiple different communication scenarios in the target geographic area, so that the communication quality of the user equipment in different scenarios in the target geographic area can be improved.

[0092] The communication optimization method provided in the embodiments of the present application can be used to obtain a target geographic area based on obstacle perception information, and then perform optimization processing on the communication coverage in the target geographic area. Because the optimization processing is performed on the communication coverage in the target geographic area, the communication quality of the user equipment in the target geographic area can be improved. In other words, the communication optimization method provided in the present application does not need to identify the identity of the user equipment to perform targeted optimization of the communication quality of the user equipment, but performs universal and non-targeted optimization of the communication quality of the user equipment in the target geographic area, thereby achieving the effect of optimizing the communication quality of the user equipment without identifying the identity of the user equipment.

[0093] As described above, in optional embodiments of the present application, the first communication device can be a network side device or user equipment. In the following, the embodiments of the present application will be described with respect to the first communication device being user equipment and the first communication device being a network side device.

[0094] First, the first communication device is user equipment.

[0095] In optional embodiments of the present application, the user equipment acquires the target geographical area in the following two possible ways: 1. The user equipment determines the target geographical area by itself; 2. The user equipment acquires the target geographical area from the network side equipment.

[0096] In optional embodiments of the present application, the user equipment determines the target geographical area by itself, including at least one of the following possible cases:

[0097] 1. The user equipment determines the target geographical area according to the configuration information sent by the network side.

[0098] For example, in one possible implementation, the configuration information sent by the network side can include a trigger condition, and then the user equipment can execute the geographical area determination process to determine the target geographical area when the condition is met.

[0099] For another example, in another possible implementation, the configuration information sent by the network side can include algorithm indication information, and then the user equipment can determine the target geographical area based on the algorithm type and / or algorithm parameters indicated by the algorithm indication information. It should be noted that the specific content of the configuration information sent by the network side is not limited in the embodiments of the present application.

[0100] 2. The user equipment acquires the obstacle perception information and determines the target geographical area according to the obstacle perception information.

[0101] In optional embodiments of the present application, the obstacle perception information can be obtained by the user equipment based on perception technology.

[0102] In some embodiments, the obstacle perception information can be obtained by the user equipment based on the target obstacle between the user equipment and the network side, or the obstacle perception information can be obtained by the user equipment based on the target obstacle between the user equipment and other user equipment. In some embodiments, for the user equipment in the non-connected state, the user equipment can perceive the target obstacle between the user equipment and other user equipment before directly communicating with other user equipment or during the process of directly communicating with other user equipment, to obtain the obstacle perception information.

[0103] In optional embodiments of the present application, the user equipment can perceive when the communication quality of the user equipment has been affected by the obstacle, to obtain the obstacle perception information. For example, if the user equipment is located in a communication shadow area blocked by the obstacle, the user equipment can perceive to obtain the obstacle perception information.

[0104] In optional embodiments of the present application, the user equipment can periodically perceive to obtain the obstacle perception information.

[0105] In optional embodiments of the present application, the user equipment can perceive the newly emerged obstacle to obtain the obstacle perception information.
