Background

With the continuous development of communication technology, the existing wireless spectrum resources have been unable to meet the requirements of users in practical use, and therefore, wireless access network devices and terminal devices for information transmission through high-frequency signals appear in the cells of the cellular communication system.

However, when the radio access network device and the terminal device transmit the high-frequency signal by using the beamforming method, the beam generated by the beamforming has directivity and is easily blocked by an obstacle, so that the signal stability is poor.

Therefore, how to transmit information by the radio access network device and the terminal device in the cell using the high-frequency signal is an urgent problem to be solved.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the embodiments of the present invention, "a plurality" means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

The terminal device according to the embodiments of the present invention may be a device providing voice and/or data connectivity to a user, a handheld device having a wireless connection function, or another processing device connected to a wireless modem. Wireless terminals, which may be mobile terminals such as mobile telephones (or "cellular" telephones) and computers having mobile terminals, such as portable, pocket, hand-held, computer-included, or vehicle-mounted mobile devices, may communicate with one or more core networks via a Radio Access Network (RAN), which may exchange language and/or data with the RAN. For example, Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), and the like. A wireless Terminal may also be referred to as a system, a Subscriber Unit (Subscriber Unit), a Subscriber Station (Subscriber Station), a Mobile Station (Mobile), a Remote Station (Remote Station), an Access Point (Access Point), a Remote Terminal (Remote Terminal), an Access Terminal (Access Terminal), a User Terminal (User Terminal), a User Agent (User Agent), a User Device (User Device), or a User Equipment (User Equipment).

The radio access network device according to the embodiments of the present invention may be a base station, an access point, or a device in an access network that communicates with a wireless terminal over an air interface through one or more sectors.

The base station may also coordinate management of attributes for the air interface. For example, the Base Station may be a Base Transceiver Station (BTS) in GSM or CDMA, a Base Station (NodeB) in WCDMA, or an evolved Node B (eNB or e-NodeB) in LTE, and the present application is not limited thereto.

With the continuous development of communication technology, the existing wireless spectrum resources cannot meet the requirements of users in practical use, so in the future 5G communication system, the wireless access network device and the terminal device can transmit information by using high-frequency signals.

Fig. 1 is an application scenario diagram provided in the embodiment of the present invention. As shown in fig. 1, when the radio access network device and the terminal device transmit information by using high frequency signals, if the high frequency signals are transmitted between the radio access network device and the terminal device in an omnidirectional antenna transmission mode, the attenuation of the high frequency signals during transmission is relatively large, so that the coverage area of a cell is small. The inner circle shown in fig. 1 with the cell antenna as the center of circle is the coverage area of the cell when the radio access network device and the terminal device transmit the high-frequency signal in the omni-directional antenna transmission mode.

In order to improve the coverage of a cell, in a future 5G communication system, a radio access network device and a terminal device may transmit a high-frequency signal in a beamforming transmission mode. The beam forming is a signal preprocessing technology based on an antenna array, that is, the beam forming can generate a beam with directivity by adjusting the weighting coefficient of each array element in the antenna array, so that obvious array gain can be obtained. Therefore, when the radio access network device and the terminal device transmit the high-frequency signal by using the beamforming transmission mode, the coverage area of the cell can be enlarged, the throughput at the edge of the cell can be improved, and the like. It should be noted that the difference between the omni-directional antenna transmission mode and the beamforming transmission mode is that the coverage area of the signal once sent by the omni-directional antenna transmission mode is the coverage area of the cell, while the signal once sent by the beamforming transmission mode can only cover a partial area of the cell, that is, the area where the terminal device is located, and the two transmission modes may be implemented by using different antennas. The transmission angle of the signal transmitted when the omni-directional antenna transmission mode is adopted may be 360 degrees, or may be an angle lower than 360 degrees, for example: 120 degrees, the specific angle can be determined according to the range of the cell to be covered.

The outer circle shown in fig. 1 with the cell antenna as the center of a circle is the coverage area of the cell when the radio access network device and the terminal device transmit the high-frequency signal in the beamforming transmission mode. However, since the beams generated using the beamformed transmission mode are directional, each beam generated using the beamformed transmission mode can only be directed in a smaller direction. For example: in fig. 1, when the radio access network device transmits a high-frequency signal to the terminal device 1 in a beamforming transmission mode, a generated beam only points to an area where the terminal device 1 is located. At this time, if an obstacle exists between the antenna and the terminal apparatus 1, the terminal apparatus 1 may not receive the signal, and reliability of transmission is reduced.

However, when the high-frequency signal is transmitted between the radio access network device and the terminal device in the omni-directional antenna transmission mode, since the signal transmitted in the omni-directional antenna transmission mode can cover the entire cell, even if an obstacle exists between the terminal device and the radio access network device, the terminal device can still receive the signal transmitted by the access network device in a manner that the signal transmitted by the omni-directional antenna is reflected by another building, and thus, the reliability of transmission can be ensured. For example: in fig. 1, when the radio access network device transmits a high-frequency signal to the terminal device 2 through the omnidirectional antenna, although an obstacle exists between the terminal device 2 and the antenna, the terminal device 2 may still receive the signal transmitted by the access network device in a manner of a signal transmitted by an antenna reflected by another building, thereby ensuring the reliability of transmission.

In view of the above situation, the transmission method provided in the embodiments of the present invention provides a hybrid transmission technology, that is, information can be transmitted between the radio access network device and the terminal device in an omni-directional antenna transmission manner and a beamforming transmission manner at the same time, so that the transmission reliability is ensured, the coverage area of the cell is expanded, and the throughput of the cell is improved. Therefore, the transmission method, the terminal device and the radio access network device provided in the embodiments of the present invention are intended to solve the technical problem of how to transmit information by using the radio access network device and the terminal device in a cell using a high frequency signal in the prior art.

The technical solution of the present invention will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.

Fig. 2 is a signaling flowchart of a transmission method according to an embodiment of the present invention. In this embodiment, the radio access network device and the terminal device both have the capability of transmitting information by simultaneously using an omni-directional antenna transmission mode and a beamforming transmission mode. The embodiment relates to a specific process that when a radio access network device uses a first time-frequency resource and a first transmission mode and terminal equipment transmit information on a first cell, the radio access network device indicates the terminal equipment to use a second time-frequency resource and a second transmission mode and the radio access network equipment to transmit information on the first cell through indication information, so that the terminal equipment simultaneously uses the first transmission mode and the second transmission mode and the radio access network equipment to transmit information on the first cell. As shown in fig. 2, the method includes:

s101, the wireless access network equipment uses a first time-frequency resource on a first cell and adopts a first transmission mode to transmit information with the terminal equipment.

Specifically, the radio access network device and the terminal device are a radio access network device and a terminal device that perform information transmission through a high-frequency signal. In this embodiment, the radio access network device currently uses the first time-frequency resource on the first cell (for example, the serving cell currently serving the terminal device) to transmit information with the terminal device by using the first transmission method, that is, the radio access network device currently uses one transmission method to transmit information with the terminal device. The first transmission mode may be an omni-directional antenna transmission mode or a beamforming transmission mode. When the radio access network equipment adopts an omnidirectional antenna transmission mode to transmit information with the terminal equipment, signals sent by the radio access network equipment and the terminal equipment can cover the whole cell. When the wireless access network equipment adopts a beam forming transmission mode to transmit information with the terminal equipment, signals sent by the wireless access network equipment and the terminal equipment can cover the area where the terminal equipment is located.

Fig. 3 is a schematic diagram of a first time-frequency resource provided by the embodiment of the invention, fig. 4 is a schematic diagram of a second time-frequency resource provided by the embodiment of the invention, and fig. 5 is a schematic diagram of a third time-frequency resource provided by the embodiment of the invention. As shown in fig. 3, the first time-frequency resource used when the radio access network device transmits information with the terminal device in the first transmission mode in the first cell may be: and occupying all frequency bands of the first cell in a frequency domain and occupying time-frequency resources for a period of time in a time domain. As shown in fig. 4, the first time-frequency resource may also be a time-frequency resource that occupies a part of a frequency band of the first cell in a frequency domain and occupies all time in a time domain. As shown in fig. 5, the first time-frequency resource may also be a time-frequency resource that occupies a partial frequency band of the first cell in a frequency domain and occupies a period of time in a time domain.

S102, the wireless access network equipment sends indication information to the terminal equipment.

Specifically, in the process that the radio access network device uses the first time-frequency resource in the first cell and adopts the first transmission mode to transmit information with the terminal device, the radio access network device may send the indication information to the terminal device to indicate that the terminal device uses the second time-frequency resource in the first cell and adopts the second transmission mode to transmit information with the radio access network device.

The second transmission mode is a transmission mode different from the first transmission mode. For example: the first transmission mode is an omnidirectional antenna transmission mode, the second transmission mode is a beam forming transmission mode, or the first transmission mode is a beam forming transmission mode, and the second transmission mode is an omnidirectional antenna transmission mode.

The second time frequency resource is different from the first time frequency resource. For example, as shown in fig. 3, when the first time-frequency resource is a time-frequency resource that occupies all frequency bands of the first cell in a frequency domain and occupies a period of time in a time domain, the second time-frequency resource may be a time-frequency resource that occupies a different time from the first time-frequency resource. At this time, the second time-frequency resource may occupy all frequency bands of the first cell in the frequency domain, or may occupy a part of frequency bands of the first cell, which is not limited. As shown in fig. 4, when the first time-frequency resource occupies a part of the frequency band of the first cell in the frequency domain and occupies all the time in the time domain, the second time-frequency resource may be a time-frequency resource occupying a different frequency band from the first time-frequency resource. At this time, the second time-frequency resource may occupy all time in the time domain, or may occupy only a period of time, which is not limited. As shown in fig. 5, when the first time-frequency resource is a time-frequency resource that occupies a part of a frequency band of the first cell in a frequency domain and occupies a period of time in a time domain, the second time-frequency resource may be a time-frequency resource that occupies a different time from the first time-frequency resource, may also be a time-frequency resource that occupies a different frequency band from the first time-frequency resource, and may also be a time-frequency resource that occupies a different time from the first time-frequency resource and occupies a different frequency band, which is not limited.

S103, the terminal equipment receives the indication information.

And S104, the terminal equipment transmits information with the wireless access network equipment by using the first time-frequency resource and adopting the first transmission mode on the first cell, and transmits information with the wireless access network equipment by using the second time-frequency resource and adopting the second transmission mode.

Specifically, after receiving the indication information sent by the radio access network device, the terminal device may transmit information with the radio access network device using the first time-frequency resource and the first transmission mode in the first cell, and transmit information with the radio access network device using the second time-frequency resource and the second transmission mode according to the indication information. For example: when the first transmission mode is an omnidirectional antenna transmission mode and the second transmission mode is a beam forming transmission mode, the terminal equipment transmits information with the wireless access network equipment by using the first time-frequency resource and the omnidirectional antenna transmission mode on the first cell, and transmits information with the wireless access network equipment by using the beam forming transmission mode and the second time-frequency resource. When the first transmission mode is a beam forming transmission mode and the second transmission mode is an omnidirectional antenna transmission mode, the terminal equipment transmits information with the wireless access network equipment by using the first time-frequency resource and the beam forming transmission mode on the first cell, and transmits information with the wireless access network equipment by using the second time-frequency resource and the omnidirectional antenna transmission mode.

The information transmitted by the terminal device and the wireless access network device in the omni-directional antenna transmission mode and the information transmitted in the beam forming transmission mode may be the same information or different information. Taking transmission of different information as an example, the terminal device and the radio access network device may transmit the control signaling (stability of the transmitted control signaling can be ensured) in an omnidirectional antenna transmission manner, and transmit the data (transmission efficiency of the data can be improved) in a beam forming transmission manner; data can also be transmitted by adopting an omnidirectional antenna transmission mode (for example, data corresponding to a low-delay high-reliability service can be determined according to the configuration of wireless access network equipment), and a beam forming transmission mode is adopted to transmit a control signaling; and an omnidirectional antenna transmission mode can be adopted to transmit a part of control signaling and a part of data, and a beam forming transmission mode can be adopted to transmit the other part of control signaling and the other part of data.

By the method, when the terminal equipment only uses the omnidirectional antenna transmission mode or the beam forming transmission mode and the wireless access network equipment to transmit information on the first cell, after receiving the indication information sent by the wireless access network equipment, the terminal equipment can simultaneously use different transmission modes and different wireless access network equipment to transmit information on different time-frequency resources, namely simultaneously use the omnidirectional antenna transmission mode and the beam forming transmission mode to transmit information with the wireless access network equipment. The omnidirectional antenna transmission mode can improve the transmission reliability, and the beam forming transmission mode can enlarge the coverage area of a large area and improve the throughput of the edge of the cell. Therefore, the wireless access network equipment and the terminal equipment transmit information simultaneously in an omnidirectional antenna transmission mode and a beam forming transmission mode, so that the coverage area of the cell is enlarged and the throughput of the cell is improved while the transmission reliability is ensured. Meanwhile, when the wireless access network equipment and the terminal equipment simultaneously use the omnidirectional antenna transmission mode and the beam forming transmission mode for information transmission, different time-frequency resources are adopted, so that mutual interference can be reduced, and the transmission reliability is improved.

The transmission method provided by the embodiment of the invention is directed to a wireless access network device and a terminal device which transmit information through high-frequency signals, when the wireless access network device uses a first time-frequency resource on a first cell and adopts a first transmission mode and the terminal device to transmit information, the wireless access network device can send indication information to the terminal device to indicate the terminal device to use a second time-frequency resource on the first cell and adopt the second transmission mode and the wireless access network device to transmit information, so that the terminal device simultaneously adopts the first transmission mode and the second transmission mode on the first cell and the wireless access network device to transmit information, namely simultaneously adopts an omnidirectional antenna transmission mode and a beam forming transmission mode to transmit information with the wireless access network device. By the method, when the radio access network equipment and the terminal equipment transmit information by using the high-frequency signal, the reliability of transmission can be ensured, the coverage range of a large cell can be expanded, and the throughput of the cell can be improved.

Fig. 6 is a flowchart illustrating another transmission method according to an embodiment of the present invention. As shown in fig. 6, this embodiment relates to a specific process of the above radio access network device sending instruction information to a terminal device, and on the basis of the above embodiment, the above S102 includes:

s201, the wireless access network equipment obtains the judgment parameter value.

Specifically, in this embodiment, the radio access network device may obtain a decision parameter value for determining whether to send the indication information to the terminal device. When the first transmission mode is an omni-directional antenna transmission mode and the second transmission mode is a beamforming transmission mode, the decision parameter may include any one of the following: cell reference signal measurement parameters, data transmission rate. Wherein, the cell reference signal corresponding to the cell reference signal measurement parameter here is: and the access network equipment adopts an omnidirectional antenna transmission mode to send the cell reference signal to the terminal equipment. When the first transmission mode is a beamforming transmission mode and the second transmission mode is an omni-directional antenna transmission mode, the decision parameter may include: cell reference signal measurement parameters.

Taking the above-mentioned decision parameter including the cell reference signal measurement parameter as an example, when the radio access network device adopts the omnidirectional antenna transmission mode or the beam forming transmission mode to transmit information with the terminal device, the radio access network device may periodically or in real time obtain the cell reference signal measurement parameter value. The cell reference signal measurement parameter value may be a value obtained by measuring a cell reference signal by a terminal device. Here, the cell reference signal measurement parameter corresponding to the cell reference signal measurement parameter value may be: the cell Reference Signal Received Power (RSRP) may also be referred to as the cell Reference Signal Receiving Quality (RSRQ). The present embodiment does not limit the manner in which the radio access network device obtains the cell reference signal measurement parameter value. For example: the radio access network equipment can receive the cell reference signal measurement parameter value directly sent by the terminal equipment. The radio access network device may further obtain the cell reference signal measurement parameter value through calculation by receiving information used for calculating the cell reference signal measurement parameter value, which is carried in the measurement report sent by the terminal device. The radio access network device may further obtain the cell reference signal measurement parameter value through other existing manners, which is not described herein again.

Taking the above-mentioned decision parameter including the data transmission rate as an example, when the wireless access network device transmits information with the terminal device in the omni-directional antenna transmission manner, the wireless access network device may obtain the data transmission rate value. The present embodiment does not limit the manner in which the radio access network device obtains the data transmission rate value. For example: the radio access network device may receive a data transmission rate value sent by the terminal device, where the data transmission rate value may be a data transmission rate value determined by the terminal device according to an actual service. The wireless access network equipment can also determine a data transmission rate value and the like according to the data volume to be sent to the terminal equipment.

S202, when the wireless access network equipment determines that the judgment parameter value meets the preset condition, the wireless access network equipment sends indication information to the terminal equipment.

Specifically, after the radio access network device obtains the decision parameter value, it may determine whether the decision parameter value satisfies a preset condition according to a preset condition corresponding to the decision parameter value. And when the judgment parameter value meets the preset condition, the wireless access network equipment sends indication information to the terminal equipment so as to indicate the terminal equipment to simultaneously adopt an omnidirectional antenna transmission mode and a beam forming transmission mode to transmit information with the wireless access network equipment.

Taking the example that the decision parameter includes a cell reference signal measurement parameter, and the radio access network device currently adopts an omni-directional antenna transmission mode and transmits information with the terminal device, at this time, the preset condition may be, for example, "the cell reference signal measurement parameter value is less than or equal to a first preset threshold". In this case, the radio access network device may determine whether the cell reference signal measurement parameter value satisfies the preset condition by determining whether the cell reference signal measurement parameter value is less than or equal to a first preset threshold. Since the cell reference signal measurement parameter value may reflect the distance between the terminal device and the cell antenna, the first preset threshold may be determined according to the coverage area of the cell omnidirectional antenna. Based on the above manner, the radio access network device may determine whether the terminal device is located at the edge of the coverage area of the omnidirectional antenna, and then when the terminal device is located at the edge of the coverage area of the omnidirectional antenna, the radio access network device may send the indication information to the terminal device to indicate that the terminal device transmits information with the radio access network device by using the omnidirectional antenna transmission manner and the beamforming transmission manner at the same time. By the method, the communication interruption between the terminal equipment and the wireless access network equipment when the terminal equipment moves to the area (such as the beam forming coverage area) outside the coverage area of the omnidirectional antenna can be avoided, the transmission reliability is ensured, and the coverage area of the cell is expanded.

Taking the above-mentioned decision parameters including data transmission rate, the current omnidirectional antenna transmission mode adopted by the wireless access network device and the information transmission between the wireless access network device and the terminal device as an example. At this time, the preset condition may be, for example, "the data transmission rate value is greater than or equal to the second preset threshold". In this case, the radio access network device may determine whether the data transmission rate value satisfies the preset condition by determining whether the data transmission rate value is greater than or equal to a second preset threshold. The second preset threshold may be specifically determined according to a system configuration. The data transmission rate value can reflect the throughput of the wireless access network equipment and the terminal equipment, so that the wireless access network equipment can judge the throughput of the wireless access network equipment and the terminal equipment, and further when the throughput of the wireless access network equipment and the terminal equipment is high, the wireless access network equipment can send indication information to the terminal equipment so as to indicate the terminal equipment to simultaneously adopt an omnidirectional antenna transmission mode and a beam forming transmission mode to transmit information with the wireless access network equipment. Because the quality of signals transmitted by the beamforming transmission mode is good when the wireless access network equipment and the terminal equipment transmit information by the beamforming transmission mode, the wireless access network equipment and the terminal equipment can transmit information of a higher modulation mode (the higher the modulation mode is, the larger the information quantity which can be transmitted by the same time-frequency resource is), and therefore when the wireless access network equipment and the terminal equipment transmit information by the omnidirectional antenna transmission mode and the beamforming transmission mode, the throughput of the terminal equipment and the wireless access network equipment can be improved, and further the throughput of a cell can be improved.

Taking the above-mentioned decision parameters including cell reference signal measurement parameters, the information transmitted by the wireless access network device and the terminal device currently using the beamforming transmission mode as an example. At this time, the preset condition may be, for example, "the cell reference signal measurement parameter value is greater than or equal to a third preset threshold". In this case, the radio access network device may determine whether the cell reference signal measurement parameter value satisfies the preset condition by determining whether the cell reference signal measurement parameter value is greater than or equal to a third preset threshold. Since the cell reference signal measurement parameter value may reflect the distance between the terminal device and the cell antenna, the third preset threshold may be determined according to the coverage area of the cell omnidirectional antenna. Based on the above manner, the radio access network device may determine whether the terminal device is located within the coverage of the omnidirectional antenna, and then when the terminal device is located within the coverage of the omnidirectional antenna, the radio access network device may send the indication information to the terminal device to indicate that the terminal device simultaneously adopts the omnidirectional antenna transmission manner and the beamforming transmission manner to transmit the information. By the method, when the terminal equipment moves to the coverage range of the omnidirectional antenna, the terminal equipment and the wireless access network equipment can simultaneously adopt a beam forming transmission mode and an omnidirectional antenna transmission mode to transmit information, so that the condition that the terminal equipment cannot transmit information with the access network equipment due to the fact that an obstacle exists between the antenna and the terminal equipment is avoided, and transmission reliability is ensured.

The transmission method provided by the embodiment of the invention is directed to a wireless access network device and a terminal device which transmit information through high-frequency signals, when the wireless access network device uses a first time-frequency resource on a first cell and adopts a first transmission mode and the terminal device to transmit information, the wireless access network device can send indication information to the terminal device when determining that a judgment parameter value meets a preset condition so as to indicate the terminal device to use a second time-frequency resource on the first cell and adopt a second transmission mode and the wireless access network device to transmit information, so that the terminal device and the wireless access network device simultaneously adopt the first transmission mode and the second transmission mode on the first cell to transmit information, namely simultaneously adopt an omnidirectional antenna transmission mode and a beam forming transmission mode to transmit information. By the method, when the radio access network equipment and the terminal equipment transmit information by using the high-frequency signal, the reliability of transmission can be ensured, the coverage range of a large cell can be expanded, and the throughput of the cell can be improved.

Fig. 7 is a signaling flowchart of another transmission method according to an embodiment of the present invention. As shown in fig. 7, this embodiment relates to a specific process of the above-mentioned radio access network device receiving capability indication information sent by the terminal device, before the step S102, the method may further include:

s301, the terminal device sends the capability indication information to the wireless access network device.

Specifically, in this embodiment, the terminal device may send the capability indication information to the radio access network device. The capability indication information is used for indicating that the terminal equipment has the capability of simultaneously adopting an omnidirectional antenna transmission mode and a beam forming transmission mode to transmit information. The wireless access network equipment sends the indication information to the terminal equipment after determining that the terminal equipment has the capability of simultaneously adopting an omnidirectional antenna transmission mode and a beam forming transmission mode to transmit information through the capability indication information. By the method, the accuracy of the indication information sent by the wireless access network equipment can be ensured, the condition that the wireless access network equipment sends the indication information to the terminal equipment which does not have the capability of simultaneously adopting an omnidirectional antenna transmission mode and a beam forming transmission mode to transmit the information is avoided, and the useless expense of the wireless access network equipment is reduced. Meanwhile, the performance of the terminal equipment with the capability of transmitting information by adopting an omnidirectional antenna transmission mode and a beam forming transmission mode is improved.

Optionally, the terminal device may send the capability indication information to the radio access network device through an access procedure when accessing the first cell, may send the capability indication information to the radio access network device after accessing the first cell, and may send the capability indication information to the radio access network device when transmitting information with the radio access network device in the first transmission mode. Of course, the terminal device may also send the capability indication information to the radio access network device in other cases, which is not limited in the present invention.

In order to reduce signaling overhead, the capability indication information may include a bit number. The value of the bit number may be 0 or 1, for example: when the capability indication information includes 0, that is, the indication terminal device has the capability of simultaneously adopting the omnidirectional antenna transmission mode and the beamforming transmission mode to transmit information, and when the capability indication information includes 1, that is, the indication terminal device does not have the capability of simultaneously adopting the omnidirectional antenna transmission mode and the beamforming transmission mode to transmit information. Or, when the capability indication information includes 1, indicating that the terminal device does not have the capability of simultaneously adopting the omnidirectional antenna transmission mode and the beamforming transmission mode to transmit information, and when the capability indication information includes 0, indicating that the terminal device has the capability of simultaneously adopting the omnidirectional antenna transmission mode and the beamforming transmission mode to transmit information.

S302, the wireless access network equipment receives the capability indication information.

The transmission method provided by the embodiment of the invention aims at the wireless access network equipment and the terminal equipment which transmit information through high-frequency signals, when the radio access network equipment uses the first time-frequency resource on the first cell and adopts the first transmission mode to transmit information with the terminal equipment, the radio access network equipment can send the indication information to the terminal equipment when determining that the terminal equipment has the capability of simultaneously adopting the omnidirectional antenna transmission mode and the beamforming transmission mode to transmit information based on the capability indication information sent by the terminal equipment, instructing the terminal device to use the second time-frequency resource on the first cell and to transmit information with the radio access network device in the second transmission mode, the terminal equipment and the wireless access network equipment transmit information on the first cell by adopting the first transmission mode and the second transmission mode simultaneously, namely, the terminal equipment and the wireless access network equipment transmit information by adopting the omnidirectional antenna transmission mode and the beam forming transmission mode simultaneously. By the method, the accuracy of the indication information sent by the wireless access network equipment can be ensured, the condition that the wireless access network equipment sends the indication information to the terminal equipment which does not have the capability of simultaneously adopting an omnidirectional antenna transmission mode and a beam forming transmission mode to transmit the information is avoided, and the useless expense of the wireless access network equipment is reduced. Meanwhile, the performance of the terminal equipment with the capability of transmitting information by adopting an omnidirectional antenna transmission mode and a beam forming transmission mode is improved.

Further, on the basis of the above embodiment, the method may further include the steps of: and the wireless access network equipment sends time-frequency resource configuration information to the terminal equipment.

Specifically, the radio access network device may send the time-frequency resource configuration information to the terminal device when the terminal device initially accesses the first cell, or before the radio access network device and the terminal device transmit information. The time frequency resource configuration information is used for indicating available time frequency resources when an omnidirectional antenna transmission mode is adopted or/and available time frequency resources when a beam forming transmission mode is adopted. The sum of the available time-frequency resources when the omnidirectional antenna transmission mode is adopted and the available time-frequency resources when the beam forming transmission mode is adopted can be the total time-frequency resources of the first cell. The size of the available time-frequency resource when the omnidirectional antenna transmission mode is adopted and the size of the available time-frequency resource when the beam forming transmission mode is adopted can be configured in advance, and the available time-frequency resource when the omnidirectional antenna transmission mode is adopted and the available time-frequency resource when the beam forming transmission mode is adopted can be dynamically determined for the wireless access network equipment according to the use condition of the current time-frequency resource of the first cell, namely the terminal equipment quantity of the first cell which currently adopts the omnidirectional antenna transmission mode to transmit information and the terminal equipment quantity of the first cell which currently adopts the beam forming transmission mode to transmit information.

In this way, when the terminal device transmits information with the radio access network device in the first cell in the first transmission mode, and transmits information with the second transmission mode, the terminal device may determine the available time-frequency resources (i.e., the first time-frequency resources or the second time-frequency resources) corresponding to the adopted transmission mode according to the adopted transmission mode and the time-frequency resource configuration information, so that the terminal device may transmit information with the radio access network device on the available time-frequency resources corresponding to the adopted transmission mode. That is, the terminal device transmits information (for example, control signaling or data) with the radio access network device by using the time-frequency resources available for the omnidirectional antenna on the first cell and by using the transmission mode of the omnidirectional antenna, and transmits information (for example, control signaling or data) with the radio access network device by using the time-frequency resources available for beamforming. By the method, when the terminal equipment transmits information with the wireless access network equipment, the terminal equipment can monitor the information sent to the terminal equipment by the wireless access network equipment on the available time-frequency resources corresponding to the adopted transmission mode, and the information transmission efficiency of the terminal equipment and the wireless access network equipment is improved.

In specific implementation, how the time-frequency resource configuration information indicates, to the terminal device, the available time-frequency resources when the omni-directional antenna transmission mode is adopted and the available time-frequency resources when the beamforming transmission mode is adopted is not limited, for example: the time-frequency resource allocation information can indicate the available time-frequency resources when the omnidirectional antenna transmission mode is adopted and the available time-frequency resources when the beam forming transmission mode is adopted to the terminal equipment by carrying the available time-frequency resources when the omnidirectional antenna transmission mode is adopted and the available time-frequency resources when the beam forming transmission mode is adopted, can indicate the available time-frequency resources when the omnidirectional antenna transmission mode is adopted and the available time-frequency resources when the beam forming transmission mode is adopted to the terminal equipment by carrying the occupation ratio of the available time-frequency resources when the omnidirectional antenna transmission mode is adopted to the total time-frequency resources of the first cell and the occupation ratio of the available time-frequency resources when the beam forming transmission mode is adopted to the total time-frequency resources of the first cell, and can indicate the available time-frequency resources when the omnidirectional antenna transmission mode is adopted and the available time-frequency resources when the beam forming transmission mode is adopted to the terminal equipment by carrying the available time-frequency resources when the omnidirectional antenna transmission mode is adopted and the beam forming transmission mode is adopted to the terminal equipment Time frequency resources available during the input mode, etc., and the method is not limited.

The transmission method provided by the embodiment of the invention aims at the wireless access network equipment and the terminal equipment which transmit information through high-frequency signals, and before the wireless access network equipment transmits information with the terminal equipment on the first cell, the wireless access network equipment can send time-frequency resource configuration information to the terminal equipment so as to indicate available time-frequency resources when an omnidirectional antenna transmission mode is adopted and available time-frequency resources when a beam forming transmission mode is adopted. Therefore, when the terminal equipment uses the first time-frequency resource, adopts the first transmission mode and the wireless access network equipment to transmit information on the first cell and uses the second time-frequency resource, adopts the second transmission mode and the wireless access network equipment to transmit information, the terminal equipment can monitor the information sent to the terminal equipment by the wireless access network equipment on the available time-frequency resource corresponding to the currently adopted transmission mode, and the efficiency of information transmission between the terminal equipment and the wireless access network equipment is improved.

The following describes the transmission method provided by the present invention in detail with reference to several specific examples.

Example 1: fig. 8 is a signaling flowchart of another transmission method according to an embodiment of the present invention. In this example, the decision parameter includes a cell reference signal measurement parameter, and the preset condition is that "the cell reference signal measurement parameter value is less than or equal to a first preset threshold". The embodiment relates to a specific process that when a wireless access network device uses a first time-frequency resource and adopts an omnidirectional antenna transmission mode and a terminal device to transmit information on a first cell, the terminal device is instructed by instruction information to use a second time-frequency resource and adopt a beam forming transmission mode and the wireless access network device to transmit information on the first cell, so that the terminal device and the wireless access network device simultaneously adopt the omnidirectional antenna transmission mode and the beam forming transmission mode to transmit information on the first cell. As shown in fig. 8, the method may include:

s401, the wireless access network equipment uses a first time-frequency resource on a first cell and adopts an omnidirectional antenna transmission mode to transmit information with the terminal equipment.

For the description of S401, reference may be specifically made to S101, which is not described again.

S402, the terminal equipment sends the cell reference signal measurement parameter value to the wireless access network equipment.

Specifically, in this embodiment, when the terminal device uses the first time-frequency resource in the first cell and adopts an omni-directional antenna transmission mode to transmit information with the radio access network device, the terminal device may receive a cell reference signal sent by the radio access network device through the omni-directional antenna. Therefore, the terminal device may measure the received cell reference signal in real time or periodically to obtain a cell reference signal measurement parameter value, for example: and the RSRP or the RSRQ is used for sending the cell reference signal measurement parameter value to the wireless access network equipment, so that the wireless access network equipment determines whether to send the indication information to the terminal equipment according to the cell reference signal measurement parameter value.

Optionally, in another implementation manner of the present invention, the terminal device may further measure the received cell reference signal after receiving the measurement indication information sent by the radio access network device. In this way, the number of times that the terminal device measures the cell reference signal can be reduced, thereby enabling the power consumption of the terminal device to be reduced.

And S403, the radio access network equipment receives the cell reference signal measurement parameter value.

S404, the wireless access network equipment judges whether the cell reference signal measurement parameter value is less than or equal to a first preset threshold value.

Specifically, the first preset threshold may be determined according to a coverage area of the cell omni-directional antenna. Since the cell reference signal measurement parameter value may reflect the distance between the terminal device and the cell antenna, the radio access network device may determine whether the terminal device is located at the edge of the coverage area of the omnidirectional antenna by determining whether the cell reference signal measurement parameter value is smaller than or equal to a first preset threshold.

S405, when the cell reference signal measurement parameter value is smaller than or equal to a first preset threshold value, the wireless access network equipment determines that the cell reference signal measurement parameter value meets a preset condition.

Specifically, if the radio access network device determines that the cell reference signal measurement parameter value is greater than the first preset threshold value according to the cell reference signal measurement parameter value, it indicates that the terminal device is still located in the coverage area of the omnidirectional antenna currently. At this time, if the radio access network device continues to use the omni-directional antenna transmission mode to transmit information with the terminal device, the transmission performance is not affected, and therefore, the radio access network device may not send the indication information to the terminal device, so as to reduce the system overhead. And if the wireless access network equipment determines that the cell reference signal measurement parameter value is less than or equal to a first preset threshold value according to the cell reference signal measurement parameter value, namely when the terminal equipment is positioned at the edge of the coverage range of the omnidirectional antenna, determining that the cell reference signal measurement parameter value meets a preset condition.

S406, the wireless access network equipment sends the indication information to the terminal equipment.

Specifically, when the radio access network device determines that the cell reference signal measurement parameter value meets the preset condition, it indicates that the terminal device is currently located at the edge of the coverage area of the omnidirectional antenna. At this time, the terminal device may move to an area outside the coverage of the omnidirectional antenna (e.g., a beamforming coverage), so that the radio access network device may send the indication information to the terminal device to indicate that the terminal device simultaneously adopts an omnidirectional antenna transmission mode and a beamforming transmission mode to transmit information with the radio access network device. By the method, when the terminal equipment moves to the area (such as the wave beam forming coverage area) outside the coverage area of the omnidirectional antenna, the terminal equipment can still adopt the wave beam forming transmission mode and the wireless access network equipment to transmit information, so that the coverage area of a cell is enlarged while the transmission reliability is ensured.

S407, the terminal device receives the indication information.

S408, the terminal device transmits information with the wireless access network device by using the first time-frequency resource and the omnidirectional antenna transmission mode on the first cell, and transmits information with the wireless access network device by using the second time-frequency resource and the beam forming transmission mode.

For the descriptions of S407 to S408, reference may be specifically made to the descriptions of S103 to S104, which are not described again.

The transmission method provided by the embodiment of the invention is directed to a wireless access network device and a terminal device which transmit information through high-frequency signals, when the wireless access network device uses a first time-frequency resource on a first cell and adopts an omnidirectional antenna transmission mode and the terminal device to transmit information, the wireless access network device can send indication information to the terminal device when the terminal device is at the edge of the coverage range of the omnidirectional antenna, so as to indicate the terminal device to use a second time-frequency resource on the first cell and adopt a beam forming transmission mode and the wireless access network device to transmit information, and therefore the terminal device and the wireless access network device simultaneously adopt the omnidirectional antenna transmission mode and the beam forming transmission mode to transmit information on the first cell. By the method, when the terminal equipment moves to the area (such as the wave beam forming coverage area) outside the coverage area of the omnidirectional antenna, the terminal equipment can still transmit information with the wireless access network equipment through the wave beam forming transmission mode, so that the coverage area of a cell is expanded while the transmission reliability is ensured.

Example 2: fig. 9 is a signaling flowchart of another transmission method according to an embodiment of the present invention. In this example, the decision parameter includes a data transmission rate, and the preset condition is that "the data transmission rate value is greater than or equal to a second preset threshold". The embodiment relates to a specific process that when a wireless access network device uses a first time-frequency resource and adopts an omnidirectional antenna transmission mode and a terminal device to transmit information on a first cell, the terminal device is instructed by instruction information to use a second time-frequency resource and adopt a beam forming transmission mode and the wireless access network device to transmit information on the first cell, so that the terminal device and the wireless access network device simultaneously adopt the omnidirectional antenna transmission mode and the beam forming transmission mode to transmit information on the first cell. As shown in fig. 9, the method may include:

s501, the wireless access network equipment uses a first time-frequency resource on a first cell and adopts an omnidirectional antenna transmission mode to transmit information with the terminal equipment.

For the description of S501, reference may be made to S101, which is not described again.

S502, the terminal equipment sends the data transmission rate value to the wireless access network equipment.

Specifically, in this embodiment, when the terminal device uses the first time-frequency resource in the first cell and transmits information to the radio access network device in an omni-directional antenna transmission manner, the terminal device may determine a data transmission rate value currently required to be used by the terminal device based on a current service type (for example, downloading a service, watching a video service, and the like), and send the data transmission rate value to the radio access network device, so that the radio access network device determines whether to send the indication information to the terminal device according to the data transmission rate value.

S503, the radio access network device receives the data transmission rate value.

Optionally, in another implementation manner of the present invention, the following steps may be further adopted for S502 to S503: the wireless access network equipment determines a data transmission rate value according to the data volume to be sent to the terminal equipment. In some embodiments, how to determine the data transmission rate value by the radio access network device according to the data amount to be sent to the terminal device may refer to the prior art.

S504, the wireless access network equipment judges whether the data transmission rate value is larger than or equal to a second preset threshold value.

Specifically, the second preset threshold may be determined according to a system configuration. Because the data transmission rate value may reflect the throughput of the radio access network device and the terminal device, the radio access network device may determine the throughput of the radio access network device and the terminal device by determining whether the data transmission rate value is greater than or equal to the second preset threshold.

And S505, when the data transmission rate value is greater than or equal to a second preset threshold value, the wireless access network equipment determines that the data transmission rate value meets a preset condition.

Specifically, if the radio access network device determines that the data transmission rate value is smaller than the second preset threshold value according to the data transmission rate value, it indicates that the current throughput of the radio access network device and the terminal device is smaller. At this time, if the radio access network device continues to use the omni-directional antenna transmission mode to transmit information with the terminal device, the transmission performance is not affected, and therefore, the radio access network device may not send the indication information to the terminal device, so as to reduce the system overhead. And if the wireless access network equipment determines that the data transmission rate value is greater than or equal to a second preset threshold value according to the data transmission rate value, namely the throughput of the wireless access network equipment and the terminal equipment is higher, determining that the data transmission rate value meets the preset condition.

S506, the wireless access network equipment sends the indication information to the terminal equipment.

Specifically, when the radio access network device determines that the data transmission rate value satisfies the preset condition, it indicates that the throughput of the radio access network device and the terminal device is high. At this time, the radio access network device and the terminal device need to use a larger data transmission rate to transmit information, so that the radio access network device can send indication information to the terminal device to indicate that the terminal device simultaneously adopts an omnidirectional antenna transmission mode and a beamforming transmission mode to transmit information with the radio access network device. Because the quality of signals transmitted by the beamforming transmission mode is good when the wireless access network equipment and the terminal equipment transmit information by adopting the beamforming transmission mode, the wireless access network equipment and the terminal equipment can transmit information with a higher modulation mode (the higher the modulation mode is, the larger the information amount transmitted at one time).

And S507, the terminal equipment receives the indication information.

And S508, the terminal equipment transmits information with the wireless access network equipment by using the first time-frequency resource and the omnidirectional antenna transmission mode on the first cell, and transmits information with the wireless access network equipment by using the second time-frequency resource and the beam forming transmission mode.

The descriptions of S507-S508 may specifically refer to the descriptions of S103-S104, which are not described again.

The transmission method provided by the embodiment of the invention is directed to a wireless access network device and a terminal device which transmit information through high-frequency signals, when the wireless access network device uses a first time-frequency resource on a first cell and adopts an omnidirectional antenna transmission mode and the terminal device to transmit information, the wireless access network device can send indication information to the terminal device when the throughput of the wireless access network device and the terminal device is large so as to indicate the terminal device to use a second time-frequency resource on the first cell and adopt a beam forming transmission mode and the wireless access network device to transmit information, so that the terminal device and the wireless access network device simultaneously adopt the omnidirectional antenna transmission mode and the beam forming transmission mode on the first cell to transmit information. By the method, when the throughput of the wireless access network equipment and the terminal equipment is large, and the wireless access network equipment and the terminal equipment can simultaneously adopt an omnidirectional antenna transmission mode and a beam forming transmission mode to transmit information, the throughput of the terminal equipment and the wireless access network equipment is improved, and further the throughput of a cell can be improved.

Example 3: fig. 10 is a signaling flowchart of another transmission method according to an embodiment of the present invention. In this example, the decision parameter includes a cell reference signal measurement parameter, and the preset condition is that "the cell reference signal measurement parameter value is greater than or equal to a third preset threshold". The embodiment relates to a specific process that when a wireless access network device uses a first time-frequency resource and adopts a beam forming transmission mode and a terminal device to transmit information on a first cell, the terminal device is instructed by indication information to use a second time-frequency resource and adopt an omnidirectional antenna transmission mode and a wireless access network device to transmit information on the first cell, so that the terminal device and the wireless access network device simultaneously adopt the omnidirectional antenna transmission mode and the beam forming transmission mode to transmit information on the first cell. As shown in fig. 10, the method may include:

s601, the wireless access network equipment uses a first time-frequency resource on a first cell and adopts a beam forming transmission mode to transmit information with the terminal equipment.

For the description of S601, reference may be specifically made to S101, which is not described again.

S602, the terminal equipment sends the cell reference signal measurement parameter value to the wireless access network equipment.

Specifically, in this embodiment, when the terminal device uses the first time-frequency resource on the first cell and transmits information with the radio access network device by using a beamforming transmission method, the terminal device may measure, in real time or periodically, the received cell reference signal after receiving the cell reference signal sent by the radio access network device through the omni-directional antenna, to obtain a cell reference signal measurement parameter value, for example: and the RSRP or the RSRQ is used for sending the cell reference signal measurement parameter value to the wireless access network equipment, so that the wireless access network equipment determines whether to send the indication information to the terminal equipment according to the cell reference signal measurement parameter value.

S603, the wireless access network equipment receives the cell reference signal measurement parameter value.

S604, the wireless access network equipment judges whether the cell reference signal measurement parameter value is larger than or equal to a third preset threshold value.

Specifically, the third preset threshold may be determined according to a coverage area of the cell omni-directional antenna. Since the cell reference signal measurement parameter value may reflect the distance between the terminal device and the cell antenna, the radio access network device may determine whether the terminal device is located within the coverage of the omnidirectional antenna by determining whether the cell reference signal measurement parameter value is equal to or greater than a third preset threshold.

The third preset threshold may be the same as the first preset threshold, and may also be greater than the first preset threshold, so as to avoid that the terminal device is continuously switched from the beamforming transmission mode to the beamforming transmission mode and the omnidirectional antenna transmission mode when the terminal device is located at the edge of the coverage area of the omnidirectional antenna, and then switched from the beamforming transmission mode and the omnidirectional antenna transmission mode to the beamforming transmission mode, thereby ensuring the stability of transmission.

S605, when the cell reference signal measurement parameter value is greater than or equal to a third preset threshold value, the wireless access network equipment determines that the cell reference signal measurement parameter value meets a preset condition.

Specifically, if the radio access network device determines that the cell reference signal measurement parameter value is smaller than the third preset threshold value according to the cell reference signal measurement parameter value, it indicates that the terminal device is still located outside the coverage area of the omnidirectional antenna currently. At this time, the radio access network device cannot transmit information with the terminal device in an omnidirectional antenna transmission manner, and therefore, the radio access network device may not send the indication information to the terminal device, so as to reduce system overhead. And if the wireless access network equipment determines that the cell reference signal measurement parameter value is larger than or equal to a third preset threshold value according to the cell reference signal measurement parameter value, namely when the terminal equipment is positioned in the coverage range of the omnidirectional antenna, determining that the cell reference signal measurement parameter value meets a preset condition.

And S606, the wireless access network equipment sends the indication information to the terminal equipment.

Specifically, when the radio access network device determines that the cell reference signal measurement parameter value meets the preset condition, it indicates that the terminal device is located within the coverage of the omnidirectional antenna. At this time, the terminal device may transmit information with the radio access network device in an omnidirectional antenna transmission manner, so that the radio access network device may send indication information to the terminal device to indicate that the terminal device transmits information with the radio access network device in an omnidirectional antenna transmission manner and a beamforming transmission manner at the same time. By the method, when the terminal equipment moves to the coverage range of the omnidirectional antenna, the terminal equipment and the wireless access network equipment can simultaneously adopt the beamforming transmission mode and the omnidirectional antenna transmission mode to transmit information, so that the condition that the terminal equipment cannot transmit the information with the access network equipment in the beamforming transmission mode due to the existence of obstacles between the antenna and the terminal equipment is avoided, and the transmission reliability is ensured.

S607, the terminal device receives the indication information.

And S608, the terminal device transmits information with the wireless access network device by using the first time-frequency resource and adopting a beam forming transmission mode on the first cell, and transmits information with the wireless access network device by using the second time-frequency resource and adopting an omnidirectional antenna transmission mode.

For the descriptions of S607 to S608, reference may be specifically made to the descriptions of S103 to S104, which are not described again.

Optionally, in another implementation manner of the present invention, if the indication information is further used for indicating a type of information transmitted by the terminal device when the omni-directional antenna transmission manner is adopted; the type of information referred to herein may include control signaling or data, among others. The terminal device may transmit, on the first cell, information other than the information corresponding to the information type indicated by the indication information, using the first time-frequency resource and using the beamforming transmission mode, and transmit, by using the second time-frequency resource and using the omnidirectional antenna transmission mode, the information corresponding to the information type indicated by the indication information, to the radio access network device.

If the radio access network device sends the time-frequency resource configuration information to the terminal device in the implementation manner, the terminal device may determine an available time-frequency resource (i.e., the first time-frequency resource or the second time-frequency resource) corresponding to the adopted transmission manner according to the adopted transmission manner and the time-frequency resource configuration information, so that the terminal device may transmit information with the radio access network device on the available time-frequency resource corresponding to the adopted transmission manner. That is, the terminal device uses the time-frequency resource available to the omnidirectional antenna on the first cell, and uses the transmission mode of the omnidirectional antenna to transmit information (for example, control signaling or data) corresponding to the information type indicated by the indication information transmitted by the radio access network device, and uses the time-frequency resource available to the beamforming transmission mode to transmit information other than the information type indicated by the indication information, by the radio access network device. For example: if the information type indicated by the indication information is a control signaling, the terminal equipment adopts a beam forming transmission mode to transmit data with the wireless access network equipment; if the information type indicated by the indication information is data, the terminal device transmits a control signaling with the radio access network device when adopting a beamforming transmission mode. By the method, when the terminal equipment transmits information with the wireless access network equipment, the terminal equipment can monitor the information sent to the terminal equipment by the wireless access network equipment on the available time-frequency resources corresponding to the adopted transmission mode, and the information transmission efficiency of the terminal equipment and the wireless access network equipment is improved.

The transmission method provided by the embodiment of the invention is directed to a wireless access network device and a terminal device which transmit information through high-frequency signals, when the wireless access network device uses a first time-frequency resource on a first cell and adopts a beam forming transmission mode and the terminal device to transmit information, the wireless access network device can send indication information to the terminal device when the terminal device is located in the coverage range of an omnidirectional antenna so as to indicate the terminal device to use a second time-frequency resource on the first cell and adopt the omnidirectional antenna transmission mode and the wireless access network device to transmit information, so that the terminal device and the wireless access network device simultaneously adopt the omnidirectional antenna transmission mode and the beam forming transmission mode to transmit information on the first cell. By the method, when the terminal equipment moves to the coverage range of the omnidirectional antenna, the terminal equipment and the wireless access network equipment can simultaneously adopt the beam forming transmission mode and the omnidirectional antenna transmission mode to transmit information, so that the condition that the terminal equipment cannot transmit the information with the wireless access network equipment in the beam forming transmission mode due to the existence of obstacles between the antenna and the terminal equipment is avoided, and the transmission reliability is ensured.

Optionally, in another implementation manner of the present invention, in order to avoid a situation that when a terminal device located within a coverage area of an omnidirectional antenna transmits information using a beamforming transmission manner and a Radio access network device, a Radio link fails due to sudden attenuation of a transmission signal due to blocking of an obstacle, so that the terminal device triggers Radio Resource Control (RRC) connection reestablishment, the Radio access network device may further pre-allocate a semi-static Resource to the terminal device on a frequency Resource available in the omnidirectional antenna transmission manner. Therefore, when the terminal device and the wireless access network device cannot communicate in a beamforming transmission mode, the terminal device and the wireless access network device also perform Control signaling interaction through the pre-configured semi-static Resource to know that the wireless access network device cannot currently communicate in the beamforming transmission mode or that the transmitting angle of the beam adopted in the current beamforming transmission mode is unavailable, so that the wireless access network device can recover the communication with the terminal device by changing the transmitting angle of the beam in beamforming and the like, the condition that the terminal device triggers Radio Resource Control (RRC) connection reestablishment is avoided, signaling overhead is reduced, and system resources are saved.

In all the embodiments described above, the radio access network device and the terminal device transmit in the first cell by using two transmission modes at the same time, or may be further extended to transmit in the first cell by using the first transmission mode and transmit in the second cell under the radio access network device by using the second transmission mode. The basic principle, procedure and technical effect are basically the same as that of using two transmission modes simultaneously in one cell, and are not described again.

Those skilled in the art will understand that the above transmission method is applicable to a terminal device having the capability of transmitting information by using both an omnidirectional antenna transmission mode and a beamforming transmission mode, and for a terminal device that cannot use both transmission modes, the radio access network device may instruct the terminal device to switch from the omnidirectional antenna transmission mode to the beamforming transmission mode according to the methods listed in the above examples (for example, when the terminal device is at the edge of the coverage area of the omnidirectional antenna, or when the terminal device moves from the coverage area of the omnidirectional antenna to the outside of the coverage area of the omnidirectional antenna, or when the throughput of the terminal device located in the coverage area of the omnidirectional antenna is large), or instruct the terminal device to switch from the beamforming transmission mode to the omnidirectional antenna transmission mode (for example, when the terminal device moves from the outside of the coverage area of the omnidirectional antenna to the coverage area of the omnidirectional antenna), etc., the implementation principle and implementation manner are basically the same as those described above, and are not described again.
