First, a method, a device, and a system involved in training a transmission beam provided by an embodiment of the present invention are explained.

Beam: A communication resource, which can be called a spatial resource, a precoding vector, that is, a transmission or reception precoding vector with energy transmission execution. In 5G and future wireless communication systems, beamforming techniques can be used between communication devices to limit the energy of the transmitted signal to a certain beam direction, thereby increasing signal and reception efficiency. Different beams can be considered as different resources, and the same information or different information can be transmitted through different beams. The beam can be divided into a transmit beam and a receive beam, and the beam transmit beam can be a signal intensity distribution formed in different directions of the space after the signal is transmitted through the antenna. The receive beam may refer to a signal strength distribution of wireless signals received from the antenna in different directions in space.

Beam pair: The transmit beam and the receive beam are a pair of beam pairs. exemplarily, taking the network device and the UE as an example, the downlink transmission beam of the network device and the corresponding UE receive beam are a pair of beams. For example, the uplink transmission beam of the UE and the receiving beam of the corresponding network device are a pair of beam pairs, and the link formed by the beam pair is called a beam pair link (BPL). Exemplarily, as shown in FIG. 1 , the network device generates multiple downlink transmission beams (ie, transmit beams) by using beamforming technology, and FIG. 1 generates four downlink transmission beams by network devices (respectively recorded as beam 1) , beam 2, beam 3 and beam 4), there are 3 receiving beams of the corresponding UE (respectively referred to as beam 5, beam 6 and beam 7), and the network device uses beam 3 to transmit downlink signals to the UE, and the UE can pass the beam 6 Receive the downlink signal sent by the network device.

Subsequently, the network device can use the downlink transmission beam to transmit a control channel, a data channel, a sounding signal, and the like.

For example, assume that the network device can generate four transmit beams, labeled as beams 1, 2, and 3, respectively; the UE can generate three receive beams, labeled as beams a, b, respectively. Then, the network device separately transmits the reference signal through the beams 1, 2, and 3; the UE receives the reference signal through the beam a, and receives the reference signal through the beam b, and then determines the reference signal estimate received by each of the receive beams according to the received reference signal. Channel quality of each beam pair (specifically: beam pair composed of beam 1 and beam a, beam pair composed of beam 2 and beam a, beam pair composed of beam 3 and beam a, beam pair composed of beam 1 and beam b The beam quality of the beam pair formed by beam 2 and beam b, the beam pair formed by beam 3 and beam b, and the downlink transmission beam satisfying the preset condition, and the determined beam pair is the beam composed of beam 3 and beam a The channel quality of the pair is the best, and the UE can feed back the identification information of the beam 3 to the network device.

The process of determining an uplink transmission beam may include: the UE transmitting one or more reference signals to the network device by using each uplink transmission beam (ie, a transmit beam), where the reference signals transmitted through different uplink transmission beams may be resource-multiplexed (for example, time domain and/or frequency domain resource multiplexing by time division, frequency division, code division mode or a combination thereof); the network device receives each uplink transmission of the UE through each of the plurality of reception beams respectively. a reference signal transmitted by the beam, and then estimating each of the UEs according to the received plurality of reference signals Uplinking the channel to the channel quality of each receive beam of the network device, and determining an uplink transmit beam whose channel quality meets a preset condition. Subsequently, the UE may use the uplink transmission beam to transmit a control channel, a data channel, a sounding signal, and the like.

It should be noted that the method for training a transmission beam provided by the embodiment of the present invention may be in a random access process. Implementation to determine an uplink transmission beam for the UE to transmit uplink information.

First, the existing LTE system is taken as an example to briefly describe the random access procedure. As shown in FIG. 5, the random access procedure includes S101-S105:

S101. The network device sends basic system information to the UE.

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

S102. The UE receives basic system information sent by the network device, and sends a preamble sequence to the network device.

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

S103. The network device receives the preamble sequence sent by the UE, and detects the received preamble sequence. If the network device detects the preamble sequence and estimates the delay of the channel transmitting the preamble sequence, the network device sends a random access response to the UE. Message.

Optionally, the random access response (RAR) is the message 2 in the random access process, and the index of the preamble sequence, the time advance, and the uplink grant may be carried in the random access response message. (uplink grant) information, etc. The uplink grant information may be used to indicate that the UE sends the time-frequency resource of the message 3.

S104. The UE receives the random access response message sent by the network device, and sends the message 3 on the time-frequency resource specified by the uplink grant information of the random access response message.

It should be noted that after the UE sends a preamble sequence, it needs to wait for a random access response message sent by the network device. In the LTE system, the random access response time window may be carried in the system information, where the random access response time window refers to a time period in which the UE attempts to receive the random access response after transmitting the random access preamble. If the UE receives the random access response in the random access response time window, the message 3 is sent on the time-frequency resource specified by the random access response; if the UE does not receive the random access response in the random access response time window , this random access process failed. The UE may re-initiate the random access procedure.

Optionally, the content of the message 3 may be not 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 competing for access networks, each UE may multiplex message 3, and carry respective identification information in message 3, so that the network device determines at least one UE. Access to the network.

S105. The network device receives the message 3 sent by the UE, and sends the message 4 to the UE.

The message 4 is a conflict resolution message. For example, in the contention-based random access procedure described above, after the UE sends the message 3 carrying the identifier information of the UE to the network device, the network device receives the message 3 and obtains from the multiple UEs. Determining that the at least one UE is a UE that can access the network, and then the network device may carry the selected identifier information of the at least one UE in the message 4 and send the information to the at least one UE, to notify the at least one UE to contend for the channel success, so that At least one UE can access the network.

At this point, the random access process ends.
