In the beamforming technology, a network device side is configured with a plurality of downlink transmission beams (hereinafter, both referred to as downlink transmission beams) and corresponding reception beams, a User Equipment (UE) side is also configured with a plurality of uplink transmission beams (hereinafter, both referred to as uplink transmission beams) and corresponding reception beams, the network device may transmit downlink data to the UE through the downlink transmission beams, the UE receives downlink data through the reception beams of the UE, and similarly, the UE may transmit uplink data to the network device through the uplink transmission beams, and the network device receives uplink data through the reception beams of the network device. Specifically, before the network device and the UE transmit uplink and downlink data using beams, first determining which beam or beams are used to transmit data and determining which beam or beams are used to receive data, taking transmitting uplink data as an example, in a random access process, the UE may transmit a reference signal to the network device using a plurality of uplink transmission beams of the UE, and after the network device receives the reference signal transmitted by the UE using a receiving beam thereof, may select one or more uplink transmission beams from the plurality of uplink transmission beams, which are higher RSRP, better RSRP, or higher RSSI, according to a Received Signal Strength Indicator (RSSI) or the like, and notify the UE of information of the selected uplink transmission beams, therefore, the UE can transmit uplink data to the network device by using the uplink transmission beam selected by the network device.

Detailed Description

The term "and/or" herein is merely an association describing an associated object, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone.

The terms "first" and "second," and the like, in the description and in the claims of embodiments of the present invention are used for distinguishing between different objects and not for describing a particular order of the objects. For example, the first uplink transmission beam and the second uplink transmission beam, etc. are used to distinguish different transmission beams, rather than to describe a specific order of transmission beams.

In the embodiments of the present invention, words such as "exemplary" or "for example" are used to mean serving as examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "e.g.," an embodiment of the present invention is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

In the description of the embodiments of the present invention, the meaning of "a plurality" means two or more unless otherwise specified. For example, a plurality of processing units refers to two or more processing units; the plurality of systems refers to two or more systems.

First, some concepts related to a method, an apparatus, and a system for training a transmission beam according to embodiments of the present invention are explained.

Beam (beam): is a communication resource, which may be referred to as a space resource, a precoding vector, i.e. refers to a transmission or reception precoding vector having energy transmission performability. In 5G and future wireless communication systems, beam forming technology can be used between communication devices to limit the energy of transmission signals within a certain beam direction, thereby increasing the efficiency of signal and reception. Different beams may be considered different resources and the same information or different information may be transmitted through different beams. The beam can be divided into a transmitting beam and a receiving beam, and the beam transmitting beam can refer to the distribution of signal intensity formed in different directions in space after the signals are transmitted by the antenna. A receive beam may refer to the distribution of signal strength of a wireless signal received from an antenna in spatially different directions.

Beam pair (beam pair): the transmit beam and the receive beam are a pair of beam pairs, for example, taking the network device and the UE as an example, a downlink transmit beam of the network device and a corresponding receive beam of the UE are a pair of beam pairs, or an uplink transmit beam of the UE and a corresponding receive beam of the network device are a pair of beam pairs, and a link formed by the beam pairs is called a Beam Pair Link (BPL). Illustratively, as shown in fig. 1, a network device generates a plurality of downlink transmission beams (i.e., transmission beams) by using a beamforming technique, in fig. 1, 4 downlink transmission beams (denoted as beam 1, beam 2, beam 3, and beam 4, respectively) are generated by the network device, there are 3 corresponding reception beams of a UE (denoted as beam 5, beam 6, and beam 7, respectively), the network device uses beam 3 to transmit a downlink signal to the UE, and the UE can receive the downlink signal transmitted by the network device through beam 6.

Before data transmission, transmission beams need to be determined first to select one transmission beam with better channel quality for transmitting data. Determining the transmission beam includes determining a downlink transmission beam and determining an uplink transmission beam.

The process of determining the downlink transmission beam may include: the network device transmits one or more reference signals to the UE through each downlink transmission beam (i.e., a transmission beam), wherein the reference signals transmitted through different downlink transmission beams may be resource-multiplexed (e.g., time-domain and/or frequency-domain resource-multiplexed by time division, frequency division, code division, or a combination thereof); the UE receives a reference signal sent by each downlink transmission beam of the network equipment through each receiving beam of the multiple receiving beams, estimates the channel quality from each downlink transmission beam of the network equipment to each receiving beam of the UE according to the received multiple reference signals, determines the downlink transmission beam of which the channel quality meets the preset condition, and feeds back the identification information of the downlink transmission beam to the network equipment. Subsequently, the network device may transmit a control channel, a data channel, or a sounding signal, etc. by using the downlink transmission beam.

For example, assume that the network device can generate 4 transmit beams, labeled as beams 1, 2, 3, respectively; the UE may generate 3 receive beams, labeled as beams a, b, respectively. Then, the network device transmits reference signals through beams 1, 2, and 3, respectively; the UE receives the reference signal through the beam a and the reference signal through the beam b, then determines the reference signal received by each receiving beam according to the received reference signal, estimates the channel quality of each beam pair (specifically, the beam pair consisting of the beam 1 and the beam a, the beam pair consisting of the beam 2 and the beam a, the beam pair consisting of the beam 3 and the beam a, the beam pair consisting of the beam 1 and the beam b, the beam pair consisting of the beam 2 and the beam b, and the beam pair consisting of the beam 3 and the beam b), and determines the downlink transmission beam satisfying a preset condition, and if the determined beam pair is the beam pair consisting of the beam 3 and the beam a with the best channel quality, the UE may feed back the identification information of the beam 3 to the network device.

The process of determining the uplink transmission beam may include: the UE transmits one or more reference signals to the network device through each uplink transmission beam (i.e., transmission beam), wherein the reference signals transmitted through different uplink transmission beams may be resource-multiplexed (e.g., time-domain and/or frequency-domain resource-multiplexed by time division, frequency division, code division, or a combination thereof); the network equipment receives a reference signal sent by each uplink transmission beam of the UE through each of the plurality of receiving beams, estimates the channel quality of each uplink transmission beam of the UE to each receiving beam of the network equipment according to the plurality of received reference signals, and determines the uplink transmission beam of which the channel quality meets the preset condition. Subsequently, the UE may transmit a control channel, a data channel, or a sounding signal, etc. using the uplink transmission beam.

It should be noted that the technical solution provided in the embodiment of the present invention is mainly discussed with respect to how to determine the uplink transmission beam, that is, the uplink transmission beam is determined based on the determination of the downlink transmission beam (how to determine the downlink transmission beam, which is not described or limited in the embodiment of the present invention). See in particular the detailed description of the examples below.

In order to solve the problems in the background art, that is, in order to reduce the influence of interference in a communication system on the accuracy of selecting an uplink transmission beam by a network device, embodiments of the present invention provide a method, an apparatus, and a system for training a transmission beam, where after a network device configures a resource (which may be referred to as a first resource) for a UE to transmit identification information of the UE using at least one uplink transmission beam, the network device may also configure a resource (which may be referred to as a second resource) for the UE to transmit uplink information using at least one uplink transmission beam, so that the UE may transmit uplink information to the network device using the uplink transmission beam on the second resource, so that the network device may more accurately select an uplink transmission beam with better signal quality from the at least one uplink transmission beam according to each uplink information transmitted by the UE using the at least one uplink transmission beam, the method is used for subsequent data transmission between the UE and the network equipment, and can improve the transmission quality of uplink data.

The method for training the beam provided by the embodiment of the invention can be applied to various wireless communication systems using the beam forming technology, such as NR systems, next generation LTE systems, Wireless Local Area Networks (WLAN) systems, Bluetooth communication systems and other wireless communication systems. Taking the NR system as an example, fig. 2 is a schematic structural diagram of the NR system according to an embodiment of the present invention. In fig. 2, the NR system may include a core network with a new air interface and an access network with a new air interface, where a functional entity of the access network includes network device 10 and UE 11, and the functional entity of the access network may further include relay device 12, where UE 11 and network device 10 may establish a connection through link 1, UE 11 may also establish a connection through link 3 with relay device 12 first, and relay device 12 then establishes a connection through link 2 with network device 10, so that UE 11 may access the access network.

It is to be understood that, in connection with fig. 2, for a network device, relay device 12 may be considered a user equipment of network device 10, and for a UE, relay device 12 may be considered a network device of UE 11.

Exemplarily, the embodiment of the present invention takes UE as a mobile phone as an example, and introduces a hardware structure of the UE. The following describes each component of the mobile phone provided by the embodiment of the present invention with reference to fig. 4. As shown in fig. 4, a mobile phone provided in an embodiment of the present invention includes: a processor 30, a Radio Frequency (RF) circuit 31, a power supply 32, a memory 33, an input unit 34, a display unit 35, and an audio circuit 36. Those skilled in the art will appreciate that the configuration of the handset shown in fig. 4 does not constitute a limitation of the handset, and may include more or fewer components than those shown in fig. 4, or may combine some of the components shown in fig. 4, or may be arranged differently than those shown in fig. 4.

The processor 30 is the control center of the handset and connects the various parts of the entire handset using various interfaces and lines. The overall monitoring of the handset is performed by executing or executing software programs and/or modules stored in the memory 33 and calling data stored in the memory 33 to perform various functions of the handset and process the data. Alternatively, processor 30 may include one or more processing units. Optionally, the processor 30 may integrate an application processor and a modem processor, wherein the application processor mainly processes an operating system, a user interface, an application program, and the like; the modem processor handles primarily wireless communications. It will be appreciated that the modem processor described above may also be a processor separate from the processor 30.

The RF circuit 31 may be used to receive and transmit signals during the transmission and reception of information or during a call. For example, the downlink information of the base station is received and then processed by the processor 30; in addition, the uplink data is transmitted to the base station. Typically, the RF circuit includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a Low Noise Amplifier (LNA), and a duplexer. In addition, the handset may also communicate wirelessly with other devices in the network via the RF circuitry 31. The wireless communication may use any communication standard or protocol, including but not limited to global system for mobile communications (GSM), General Packet Radio Service (GPRS), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), LTE, email, and Short Messaging Service (SMS), among others.

The power supply 32 may be used to power various components of the handset, and the power supply 32 may be a battery. Optionally, the power source may be logically connected to the processor 30 through a power management system, so as to implement functions of managing charging, discharging, power consumption management, and the like through the power management system.

The memory 33 may be used to store software programs and/or modules, and the processor 30 executes various functional applications and data processing of the mobile phone by operating the software programs and/or modules stored in the memory 33. The memory 33 may mainly include a storage program area and a storage data area, wherein the storage program area may store an operating system, an application program required by at least one function (such as a sound playing function, an image playing function, etc.), and the like; the storage data area may store data (such as audio data, image data, a phonebook, etc.) created according to the use of the cellular phone, and the like. Further, the memory 33 may include high speed random access memory, and may also include non-volatile memory, such as at least one magnetic disk storage device, flash memory device, or other volatile solid state storage device.

The input unit 34 may be used to receive input numeric or character information and generate key signal inputs related to user settings and function control of the cellular phone. Specifically, the input unit 34 may include a touch screen 341 and other input devices 342. The touch screen 341, also called a touch panel, may collect touch operations of a user on or near the touch screen 341 (for example, operations of the user on or near the touch screen 341 using any suitable object or accessory such as a finger or a stylus pen), and drive the corresponding connection device according to a preset program. Alternatively, the touch screen 341 may include two parts, a touch detection device and a touch controller. The touch detection device detects the touch direction of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch sensing device, converts the touch information into touch point coordinates, sends the touch point coordinates to the processor 30, and can receive and execute commands sent by the processor 30. In addition, the touch screen 341 may be implemented in various types, such as a resistive type, a capacitive type, an infrared ray, and a surface acoustic wave. Other input devices 342 may include, but are not limited to, one or more of a physical keyboard, function keys (such as volume control keys, power switch keys, etc.), a trackball, a mouse, and a joystick.

The display unit 35 may be used to display information input by the user or information provided to the user and various menus of the mobile phone. The display unit 35 may include a display panel 351. Alternatively, the display panel 351 may be configured in the form of a Liquid Crystal Display (LCD), an organic light-emitting diode (OLED), or the like. Further, the touch screen 341 may cover the display panel 351, and when the touch screen 341 detects a touch operation on or near the touch screen, the touch screen is transmitted to the processor 30 to determine the type of the touch event, and then the processor 30 provides a corresponding visual output on the display panel 351 according to the type of the touch event. Although in fig. 4, the touch screen 341 and the display panel 351 are two separate components to implement the input and output functions of the mobile phone, in some embodiments, the touch screen 341 and the display panel 351 may be integrated to implement the input and output functions of the mobile phone.

Audio circuitry 36, a speaker 361, and a microphone 362 for providing an audio interface between a user and a cell phone. In one aspect, the audio circuit 36 may transmit the electrical signal converted from the received audio data to the speaker 361, and the audio signal is converted into a sound signal by the speaker 361 for output. On the other hand, the microphone 362 converts the collected sound signals into electrical signals, which are received by the audio circuit 36 and converted into audio data, which are then output by the processor 30 to the RF circuit 31 for transmission to, for example, another cellular phone, or output by the processor 30 to the memory 33 for further processing.

Optionally, the handset as shown in fig. 4 may also include various sensors. Such as gyroscope sensors, hygrometer sensors, infrared sensors, magnetometer sensors, etc., and will not be described in detail herein.

Optionally, the mobile phone shown in fig. 4 may further include a Wi-Fi module, a bluetooth module, and the like, which are not described herein again.

It should be noted that the method for training a transmission beam provided in the embodiment of the present invention may be implemented in a random access process, so as to determine an uplink transmission beam used for the UE to send uplink information.

First, taking the existing LTE system as an example, a random access procedure is briefly described, as shown in fig. 5, the random access procedure includes S101 to S105:

s101, the network equipment sends basic system information to the UE.

The basic system information may be a System Information Block (SIB), such as SIB2, which is system information block 2. The basic system information includes some parameter configuration information of the preamble sequence configured for the UE by the network device.

S102, the UE receives basic system information sent by the network equipment and sends a leader sequence to the network equipment.

After the UE receives the basic system information sent by the network device, the UE may determine a format of the preamble sequence according to the basic system information, the UE sends a time-frequency resource of the preamble sequence, and the UE sends the preamble sequence of a specified format on the time-frequency resource configured for the UE by the network device, where the preamble sequence is used to notify the network device that the UE has a random access request.

S103, the network equipment receives the leader sequence sent by the UE, detects the received leader sequence, and sends a random access response message to the UE if the network equipment detects the leader sequence and estimates the time delay of a channel for transmitting the leader sequence.

Optionally, the random access response message (RAR) is a message 2 in the random access process, and the random access response message may carry an index of a preamble sequence, a time advance (time advance), uplink grant (uplink grant) information, and the like. The uplink grant information may be used to indicate time-frequency resources for the UE to send the message 3.

S104, the UE receives the random access response message sent by the network equipment and sends a message 3 on the time-frequency resource designated by the uplink authorization information of the random access response message.

It should be noted that after the UE sends one preamble sequence, the UE needs to wait for the random access response message sent by the network device. In the LTE system, a random access response time window may be carried in the system information, where the random access response time window refers to a time period for attempting to receive a random access response after the UE transmits a random access preamble. If the UE receives the random access response in the random access response time window, sending a message 3 on a time-frequency resource appointed by the random access response; if the UE does not receive the random access response within the random access response time window, the random access procedure fails. The UE may reinitiate the random access procedure.

Optionally, the content of the message 3 may not be limited, and the message 3 may include a Radio Resource Control (RRC) connection request, a control message, and service data. For example, in a contention-based random access procedure, there may be multiple UEs contending for access to a network, and each UE may multiplex the message 3 and carry respective identification information in the message 3, so that the network device determines that at least one UE accesses the network.

S105, the network equipment receives the message 3 sent by the UE and sends a message 4 to the UE.

For example, in the contention based random access process, after the UE sends the message 3 carrying the identification information of the UE to the network device, the network device receives the message 3 and determines that at least one UE is a UE that can access the network from the multiple UEs, and then the network device may carry the identification information of the selected at least one UE in the message 4 and send the message to the at least one UE to notify the at least one UE that the contention channel succeeds, so that the at least one UE can access the network.

At this point, the random access procedure ends.

The method for training a transmission beam according to the embodiment of the present invention is described in detail below with reference to the above random access procedure, and as shown in fig. 6, the method may include S201 to S215:

s201, the network equipment sends synchronization information to the UE.

The synchronization information may include a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS), a Master Information Block (MIB), and an SIB.

In the embodiment of the invention, the synchronization signal is used for time synchronization, frequency synchronization, symbol synchronization, frame synchronization, cyclic prefix and cell identification acquisition and the like between the UE and the network equipment; the MIB and SIB are both system information, and mainly include some system information necessary for the UE to operate in a certain cell, such as a cell identifier, an uplink/downlink subframe ratio, and a neighbor cell identifier. The MIB may be transmitted on a Physical Broadcast Channel (PBCH), and the SIB may be transmitted on a Physical Downlink Shared Channel (PDSCH).

Optionally, the information carried in the SIB may further include at least one of the following a1-a 2:

a1, a mapping relationship between Physical Random Access Channel (PRACH) resources and identification information of at least one uplink transmission beam of the first UE.

The PRACH resource is used for the UE to send a preamble sequence, and may include a time domain resource and a frequency domain resource, where the time domain resource may include at least one of the following resources: the start time, end time, duration, symbols (e.g., OFDM symbols), slots, subframes, mini-slots, etc., of the transmission preamble sequence. The frequency domain resources may include at least one of the following resources: frequency band, sub-band, physical resource block, frequency domain location, subcarrier, etc.

The mapping relationship between the PRACH resource and the identification information of the at least one uplink transmission beam of the first UE may be understood as a mapping relationship between the PRACH resource and the at least one uplink transmission beam of the first UE, and the network device may instruct the first UE to transmit the preamble sequence on different PRACH resources when the first UE transmits the preamble sequence on different uplink transmission beams, for example, the first UE may transmit the preamble sequence on the first PRACH resource by using beam 1, and the first UE may transmit the preamble sequence on the second PRACH resource by using beam 2.

It should be noted that, in this embodiment of the present invention, the first PRACH resource is different from the second PRACH resource, which means that the time domain resource or the frequency domain resource of the first PRACH resource is different from that of the first PRACH resource, where the time domain resource of the first PRACH resource is different from that of the second PRACH resource, and at least one of the listed time domain resources (i.e., a start time, an end time, a duration, a symbol (e.g., an OFDM symbol), a slot, a subframe, a mini-subframe, and a mini-slot of a transmission preamble sequence) is different from at least one of the time domain resources (also including at least one of the listed time domain resources) corresponding to the second PRACH resource.

For example, assuming that the first UE has 3 uplink transmission beams, table 1 shows an example of a mapping relationship between PRACH resources and identification information of the transmission beam of the first UE.

TABLE 1

PRACH resource	Identification of transmission beams
		First PRACH resource	beam	1
Second PRACH resource	beam 2
		Third PRACH resource	beam 3

With reference to table 1, the network device may carry a mapping relationship between the PRACH resource and the identification information of at least one uplink transmission beam of the first UE in the SIB, and send the mapping relationship to the first UE.

A2, mapping relation between the preamble sequence sent by the first UE and the identification information of at least one uplink transmission beam of the first UE.

In this embodiment of the present invention, a mapping relationship between a preamble sequence sent by a first UE and identification information of at least one uplink transmission beam of the first UE may be understood as a mapping relationship between a preamble sequence sent by the first UE and at least one uplink transmission beam of the first UE, where the preamble sequences sent by the first UE using different transmission beams may be the same or different, and the network device may instruct the first UE to use the preamble sequence sent by the transmission beam, for example, the first UE uses beam 1 to send the first preamble sequence, and the first UE uses beam 2 to send the second preamble sequence.

Also, for example, assume that the first UE has 3 uplink transmission beams, as shown in table 2, there is an example of a mapping relationship between a preamble and identification information of the transmission beam of the first UE.

TABLE 2

Leader sequence	Identification of transmission beams
		First preamble	beam	1
Second preamble	beam 2
		Third preamble	beam 3

With reference to table 2, the network device may carry a mapping relationship between the preamble sequence and the identification information of at least one uplink transmission beam of the first UE in the SIB, and send the mapping relationship to the first UE.

Optionally, in this embodiment of the present invention, the network device may further send, to the first UE, a mapping relationship between the PRACH resource and at least one downlink transmission beam of the network device (the at least one downlink transmission beam is at least one downlink transmission beam of the network device selected by the UE), or send, to the first UE, a mapping relationship between the preamble sequence and at least one downlink transmission beam of the network device.

In this embodiment of the present invention, the identification information of the transmission beam may be any one of the following information: characteristics of the transmission beam (i.e., ID (identity) of the transmission beam), an ID generated based on the ID of the transmission beam, a name of the transmission beam, an index generated based on the index of the transmission beam, a derivative value of the ID of the transmission beam, a derivative value of the name of the transmission beam, a derivative value of the index of the transmission beam, a hash value of the ID of the transmission beam, a hash value of a name of the transmission beam, a hash value of an index of the transmission beam, a truncated value of an ID of the transmission beam, a truncated value of a name of the transmission beam, a truncated value of an index of the transmission beam, a hash value of an ID of the transmission beam combined with plaintext information, a hash value of a name of the transmission beam combined with plaintext information, a hash value of an index of the transmission beam combined with plaintext information, a bit table of an ID of the transmission beam, a bit table of a name of the transmission beam, a bit table of an index of the transmission beam, a bit table of the transmission beam, and the like.

S202, the first UE receives the synchronization information sent by the network equipment.

In the embodiment of the invention, after the first UE receives the synchronization information sent by the network equipment, the first UE can synchronize with the time and the frequency of the network equipment according to the synchronization information, so that the UE can access the network conveniently.

S203, the first UE transmits a preamble sequence to the network device using at least one uplink transmission beam.

In the embodiment of the present invention, the first UE may carry the preamble sequence in the message 1 in the random access process and send the preamble sequence to the network device, and in the process that the first UE uses at least one uplink transmission beam to send the preamble sequence, the first UE may explicitly indicate or implicitly indicate the transmission beam used by the first UE.

The method for the first UE to explicitly indicate the transmission beam used by the first UE may include: when the first UE transmits the preamble sequence to the network device using at least one uplink transmission beam, the first UE carries the identification information of the at least one uplink transmission beam, so that the transmission beam used by the first UE can be indicated to the network device. For example, when the first UE transmits the preamble sequence to the network device using beam 1 of the first UE, the first UE may carry the identifier of beam 1 (for example, beam 1).

Optionally, in this embodiment of the present invention, the resource capable of carrying the identification information of the uplink transmission beam of the first UE may be acquired from an SIB, or may be acquired from a resource predefined or agreed by the network device and the first UE, so that the first UE sends the identification information of at least one uplink transmission beam of the first UE on the corresponding resource.

The method for the first UE to implicitly indicate the transmission beam used by the first UE may include: the first UE indicates the transmission beam used by the first UE according to the mapping relation between the PRACH resource and the identification information of the at least one uplink transmission beam of the first UE or the mapping relation between the preamble sequence and the at least one uplink transmission beam of the first UE.

In this embodiment of the present invention, after the first UE receives the synchronization information, the first UE may obtain, from an SIB message, a mapping relationship between the PRACH resource and the identification information of the at least one uplink transmission beam of the first UE, or the first UE may obtain, from the SIB message, a mapping relationship between the preamble sequence and the identification information of the at least one uplink transmission beam of the first UE, where for a description of the mapping relationship between the PRACH resource and the identification information of the at least one uplink transmission beam of the first UE, table 1 and other related descriptions in S201 above may be referred to, and for a description of the mapping relationship between the preamble sequence and the identification information of the at least one uplink transmission beam of the first UE, table 2 and other related descriptions in S201 above may be referred to.

Exemplarily, with reference to table 1 above, if the first PRACH resource has a mapping relationship with beam 1, the first UE transmits a preamble sequence on the first PRACH resource, which indicates that the first UE transmits the preamble sequence using beam 1; with reference to table 2, if the first preamble sequence has a mapping relationship with the beam 1, the preamble sequence sent by the first UE is the first preamble, and identifies that the first UE uses the beam 1 to send the preamble sequence.

Optionally, in this embodiment of the present invention, in a process that the first UE uses at least one uplink transmission beam to send the preamble sequence, the first UE may further explicitly or implicitly indicate at least one downlink transmission beam of the network device selected by the first UE.

The method for the first UE to explicitly indicate at least one downlink transmission beam of the network equipment selected by the first UE comprises the following steps: when the first UE sends the preamble sequence to the network device using at least one uplink transmission beam, the first UE carries the identification information of at least one downlink transmission beam of the network device selected by the first UE. For example, when the first UE sends the preamble sequence to the network device, if the first UE carries the identification information of the first beam of the network device, it indicates that the downlink transmission beam of the network device selected by the first UE is the first beam, and if the first UE carries the identification information of the second beam of the network device, it indicates that the downlink transmission beam of the network device selected by the first UE is the second beam.

The method for the first UE to implicitly indicate the at least one downlink transmission beam of the network device selected by the first UE may include: the first UE indicates the downlink transmission beam of the network equipment selected by the first UE according to the mapping relation between the PRACH resource and the identification information of the at least one downlink transmission beam of the network equipment or the mapping relation between the preamble sequence and the at least one downlink transmission beam of the network equipment.

For example, after receiving the synchronization information, the first UE may obtain, from the SIB message, a mapping relationship between the PRACH resource and the identification information of the at least one downlink transmission beam of the network device, or the first UE may obtain, from the SIB message, a mapping relationship between the preamble sequence and the identification information of the at least one downlink transmission beam of the network device. If the first PRACH resource has a mapping relationship with a first beam of the network device, the first UE sends a preamble sequence on the first PRACH resource, indicating that a downlink transmission beam of the network device selected by the first UE is a first downlink transmission beam (i.e., indicating that the network device sends downlink information to the first UE using the first downlink transmission beam); if the first preamble has a mapping relationship with the first beam of the network device, the first UE sends the first preamble to the network device, which indicates that the downlink transmission beam of the network device selected by the first UE is the first downlink transmission beam.

It should be noted that, in the embodiment of the present invention, the first UE may send different preamble sequences to the network device by using different uplink transmission beams, and the first UE may also send the same preamble sequence to the network device by using different uplink transmission beams.

Alternatively, the network device may know which transmission beam used by the first UE to transmit the preamble sequence according to the implicit indication of the first UE (i.e., the first UE implicitly indicates the transmission beam used by the first UE as described in S204 above).

S205, the network equipment sends the first resource information to the first UE.

For example, the at least one first uplink transmission beam includes beam 1, beam 2, and beam 3, and the first UE sends the identification information of the first UE to the network device by using the three beams one by one, that is, the UE first sends the identification information of the first UE to the network device by using beam 1, then sends the identification information of the first UE to the network device by using beam 2, and finally sends the identification information of the first UE to the network device by using beam 3. The order in which the first UE uses the beam 1, the beam 2, and the beam 3 is not particularly limited.

It should be noted that, in the embodiment of the present invention, the network device may configure, according to the PRACH resource used when the first UE sends the preamble sequence, the second resource for the first UE, for example, if the PRACH resource used by the first UE satisfies that n uplink transmission beams are used to send the preamble sequence, the second resource configured for the first UE by the network device satisfies that n uplink transmission beams are used to send the uplink information.

For other relevant descriptions of the second resource, reference may be made to the specific description of the first resource and the PRACH resource in the foregoing embodiment, and details are not described here again.

In the embodiment of the present invention, the network device may determine, according to the preamble sequence received and transmitted through different uplink transmission beams (i.e., at least one uplink transmission beam), a part of uplink transmission beams with better channel quality from at least one first uplink transmission beam.

It should be noted that, since the method for the network device to determine at least one first uplink transmission beam according to the preamble sequence sent by the first UE is similar to the method for the network device to determine at least one second uplink transmission beam from at least one uplink transmission beam according to the uplink information sent by the first UE in S213, for the detailed process for the network device to determine at least one first uplink transmission beam according to the preamble sequence sent by the first UE, reference may be made to the related description in S213, which is not described herein again.

In the method for training transmission beams provided in the embodiment of the present invention, in a process that a first UE accesses a network, after a network device receives a preamble sequence sent by the first UE using at least one uplink transmission beam, the network device sends first resource information to the first UE, and then the first UE may send, on a first resource indicated by the first resource information, identification information of the first UE to the network device using the at least one first uplink transmission beam, and after the network device receives the identification information of the first UE, the network device may also send, to the first UE, second resource information for the first UE to send, on a second resource indicated by the second resource information, uplink information to the network device using the at least one uplink transmission beam, so that the network device may determine at least one second uplink transmission beam from the at least one uplink transmission beam according to the uplink information sent by the first UE, and transmitting information of the at least one second uplink transmission beam to the first UE.

Optionally, in this embodiment of the present invention, in a case that the network device receives identification information of at least two UEs transmitted by at least two UEs on the first resource, the network device may transmit identification information of each UE to the at least two UEs, and the network device may configure, for each of the at least two UEs, a respective second resource for transmitting uplink information, and after the network device transmits the respective second resource information of the at least two UEs to the at least two UEs, transmit, to each of the at least two UEs, first indication information for instructing each UE to transmit uplink information using at least one uplink transmission beam of each UE, that is, in this case, for each UE, the network device may interact with the network device to perform the above-mentioned S209-S219, so that the network device may simultaneously select uplink transmission beams of the at least two UEs, namely, the training of the transmission beams with at least two UEs is completed simultaneously, so that the efficiency of uplink transmission beam selection can be improved.

To sum up, in the method for training transmission beams provided in the embodiment of the present invention, when the network device has a judgment conflict, the network device may configure the second resource for the first UE, and determine at least one second uplink transmission beam from the at least one uplink transmission beam according to the uplink information sent by the first UE on the second resource by using the at least one uplink transmission beam, so as to improve accuracy of training the uplink transmission beam, and thus improve transmission quality of uplink data.

Optionally, in this embodiment of the present invention, the network device may further send, to the first UE, an order of uplink transmission beams that is indicated by the network device and used for the first UE to send the uplink information on the second resource, for example, it is assumed that the first UE sends the uplink information to the network device using 3 uplink transmission beams, and the 3 uplink transmission beams are respectively denoted as beam 1, beam 2, and beam 3, and the network device may indicate the order in which the first UE sends the uplink information using the 3 uplink transmission beams, for example, the network device may indicate that the first UE sends the uplink information to the network device using beam 3 first, then sends the uplink information to the network device using beam 1, and finally sends the uplink information to the network device using beam 2.

Optionally, in this embodiment of the present invention, the network device may further group the at least one second uplink transmission beam determined by the network device, and then send the group information to the first UE. The grouping information includes at least one item of group identification information and identification information of an uplink transmission beam corresponding to the group identification information. The grouping information of the transmission beams may indicate which transmission beams are in a group in at least one second uplink transmission beam of the first UE, so that when the first UE fails to transmit uplink data to the network device using one transmission beam (for example, beam 1) of the at least one second uplink transmission beam, the first UE may transmit uplink data to the network device using another transmission beam in the same transmission beam group as beam 1, so as to ensure that the network device successfully receives the uplink data transmitted by the first UE.

Specifically, the network device groups the at least one second uplink transmission beam according to a predetermined range of at least one of the strength, the path loss, the SNR, the RSRP, the RSRQ, and the RSSI of a received signal of the uplink information transmitted by the first UE through the at least one second uplink transmission beam. For example, taking the predetermined range of the received signal strength as an example, the network device divides the second uplink transmission beams with the received signal strength within the same predetermined range into one transmission beam group, for example, the predetermined range may be three intervals, so that at least one second uplink transmission beam may be divided into three groups.

Optionally, the network device may further group the at least one second uplink transmission beam according to a characteristic of spatial quasi-correlation of the at least one second uplink transmission beam, and divide the spatial quasi-correlation transmission beam into one transmission beam group.

It should be noted that, in the embodiment of the present invention, information similar to the identification information of the transmission beam described in the foregoing embodiment may be taken as group identification information, and details are not described here again.

It should be noted that, in the embodiment of the present invention, the identification information of the indicated uplink transmission beam, the type of the uplink information, the number of times of transmitting the uplink information, the sequence of the uplink transmission beam, and the packet information sent by the network device are carried in an SIB and sent to the first UE.
