Description

Information transmission method, network device and terminal device

Technical Field

The present application relates to the field of communications, and more particularly, to a method for transmitting information, a network device, and a terminal device.

Background Art

In the 5G system, or also known as the New Radio (NR) system, multi-beam can be used to achieve coverage in different directions and areas. For uplink transmission, the network device has multiple uplink receive beams, and the terminal device has multiple uplink transmit beams. The uplink receive beams and the uplink transmit beams need to match to obtain good reception effects. If the matching is not good, it will lead to poor uplink reception performance or even ineffective reception.

When a terminal device accesses a network device, it often needs to try using different uplink transmit beams to send signals. The network device also needs to try different uplink receive beams to find the best matching uplink transmit beam and uplink receive beam. Network devices often have a large number of uplink receive beams. If the terminal device sequentially tries each uplink transmit beam to match the signal conditions of each receive beam of the network device, determining which uplink transmit beam to use for random access signals to access the network device will result in significant access latency.

It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and/or" is simply a description of an association between related objects, indicating that three possible relationships exist. For example, "A and/or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character "/" generally indicates that the related objects are in an "or" relationship.

When a terminal device that is using network services moves from one cell (called the "source cell") to another cell (called the "target cell"), or due to reasons such as wireless transmission service load adjustment, activation operation maintenance, equipment failure, etc., in order to ensure communication continuity and service quality, it is necessary to transfer the communication link between the terminal device and the source cell to the target cell. This process is the cell switching process.

In the LTE system, terminal device cell handover can be categorized as intra-site handover (i.e., the source and target cells belong to the same network device) or inter-site handover (i.e., the source and target cells belong to different network devices). Inter-site handover can also include X2-based handover and S1-based handover. X2-based handover can be performed when the X2 interface data is fully configured and working properly. Generally speaking, X2-based handover has a higher priority than S1-based handover.

The following describes a method 500 for transmitting information according to an embodiment of the present application from the perspective of a target cell in conjunction with FIG5 . Specifically, the method 500 can be executed by a network device to which the target cell belongs. As shown in FIG5 , the method 500 includes:

501. The target cell obtains configuration information of a measured signal, where the configuration information of the measured signal is used by a terminal device to send the measured signal according to the configuration information of the measured signal.

502. The target cell determines, according to the measured signal sent by the terminal device, a beam corresponding to at least one uplink transmission channel of the target cell;

503. The target cell transmits the at least one uplink transmission channel of the target cell using a beam corresponding to the at least one uplink transmission channel of the target cell.

Specifically, the target cell can obtain the configuration information of the measured signal. Optionally, the configuration information of the measured signal can be determined by negotiation between the source cell and the target cell. At this time, the target cell can directly obtain the configuration information of the measured signal, or the configuration information of the measured signal can also be sent by the source cell to the target cell. For example, the source cell can determine that the information of the signal currently being periodically sent by the terminal device is the configuration information of the measured signal, and then send the determined configuration information of the measured signal to the target cell.

Optionally, in some embodiments, the configuration information of the measured signal includes at least one of the following:

Send information about the time domain resources used by the measured signal, send information about the frequency domain resources used by the measured signal, send information about the channel or signal resources used by the measured signal, and the sending method of the measured signal.

After the target cell learns the configuration information of the measured signal, it can measure the measured signal on the resources indicated by the configuration information of the measured signal, thereby determining the beam corresponding to at least one uplink transmission channel of the target cell. The target cell can then use the determined beam corresponding to the at least one uplink transmission channel to transmit the at least one uplink transmission channel. Because the beam corresponding to the at least one uplink transmission channel is determined by the target cell using the measured signal sent by the measurement terminal device, the beam corresponding to the at least one uplink transmission channel has better reception performance, thereby improving uplink transmission performance.

Optionally, in some embodiments, the method further comprises:

The target cell determines, based on the measured signal sent by the terminal device, identification information of a beam corresponding to at least one uplink transmission channel of the terminal device and/or resource information used to transmit the at least one uplink transmission channel;

The target cell sends a first notification message to the source cell, and the first notification message includes identification information of the beam corresponding to at least one uplink transmission channel of the terminal device determined by the target cell, and/or resource information used to transmit the at least one uplink transmission channel.

Specifically, the target cell can also determine the identification information of the beam corresponding to at least one uplink transmission channel of the terminal device, and/or the resource information for transmitting the at least one uplink transmission channel based on the measured signal sent by the terminal device. The target cell can also send a first notification message to the source cell to inform the source cell of the identification information of the beam corresponding to at least one uplink transmission channel of the terminal device determined by the target cell, and/or the resource information for transmitting the at least one uplink transmission channel. Since the terminal device has not yet accessed the target cell and cannot communicate with the target cell, the source cell can forward the above message determined by the target cell to the terminal device, so that the terminal device can access the target cell using the resources indicated by the above message. Therefore, it avoids the problem that the terminal device needs to try to use different transmission beams to send random access-related signals when accessing the target cell, resulting in excessive access delay.

Optionally, in some embodiments, the configuration information of the measured signal is determined by negotiation between the source cell and the target cell.

That is to say, the source cell and the target cell belong to different network devices, and the configuration information of the measured signal can be determined by the two network devices through signaling interaction, or if the source cell and the target cell belong to the same network device, the configuration information of the measured signal can be determined by this network device.

Optionally, in some embodiments, the target cell acquiring configuration information of the measured signal includes:

The target cell receives the configuration information of the measured signal sent by the source cell, where the configuration information of the measured signal is determined by the source cell based on information of the signal periodically sent by the terminal device.

Specifically, the configuration information of the measured signal can be determined by the source cell. If the terminal device is periodically sending a first signal, the source cell can also determine the configuration information of the measured signal based on the information of the first signal, that is, the signal being sent by the terminal device can be used as the measured signal for measurement in the target cell.

Optionally, in some embodiments, the identification information of the beam corresponding to the at least one uplink transmission channel of the terminal device includes a beam identifier or number of the beam corresponding to the at least one uplink transmission channel of the terminal device;

The resource information used to transmit the at least one uplink transmission channel includes at least one of the following:

Information on time domain resources used to transmit the at least one uplink transmission channel and information on frequency domain resources used to transmit the at least one uplink transmission channel.

Optionally, in some embodiments, the source cell and the target cell belong to the same network device.

In this case, the handover of the terminal device between the source cell and the target cell is an intra-site handover, and the source cell and the target cell negotiate the configuration information of the measured signal, and the target cell sends the first notification message to the source cell, which can all be executed in S205 shown in Figure 2.

Optionally, in some embodiments, the source cell and the target cell belong to different network devices.

In this case, the handover of the terminal device between the source cell and the target cell belongs to inter-site handover. For inter-site handover based on the X2 interface, the source cell and the target cell negotiate the configuration information of the measured signal, or the target cell sends a first notification message to the source cell, which can be performed in S305 and S307 shown in Figure 3. That is, the source cell and the target cell can negotiate the configuration information of the measured signal through a handover request message and a handover request confirmation message, or the first notification message can be a handover request confirmation message. Alternatively, for inter-site handover based on the S1 interface, the source cell and the target cell negotiate the configuration information of the measured signal, or the target cell sends a first notification message to the source cell, which can be performed in some steps of S405, S406, S408 and S409 shown in Figure 4.

The above text, in conjunction with FIG5 , describes in detail the method for transmitting information according to an embodiment of the present invention from the perspective of the target cell. The following text, in conjunction with FIG6 , describes in detail the method for transmitting information according to an embodiment of the present invention from the perspective of the terminal device. It should be understood that the description on the target cell side corresponds to the description on the terminal device side. Similar descriptions can be found above. To avoid repetition, they will not be repeated here.

FIG6 is a schematic flowchart of a method 600 for transmitting information according to an embodiment of the present application, described from the perspective of a terminal device. As shown in FIG6 , the method 600 includes:

601. The terminal device sends a measured signal, where the measured signal is used by a target cell to determine identification information of a beam corresponding to at least one uplink transmission channel of the terminal device and/or resource information for transmitting the at least one uplink transmission channel.

602. The terminal device receives a notification message from a source cell, where the notification message includes identification information of a beam corresponding to at least one uplink transmission channel of the terminal device determined by the target cell, and/or resource information for transmitting the at least one uplink transmission channel.

Specifically, the terminal device can send a measured signal, and the measured signal can be used by the target cell to determine the identification information of the beam corresponding to at least one uplink transmission channel of the terminal device by measuring the measured signal, and/or the resource information for transmitting the at least one uplink transmission channel. The terminal device can also receive a notification message from the source cell, and the notification message includes the above information determined by the target cell, so that the terminal device can use the beam corresponding to at least one uplink transmission channel of the terminal device to transmit the uplink transmission channel. Since the beam corresponding to at least one uplink transmission channel of the terminal device is determined by the target cell through measuring the measured signal, the terminal device can directly access the target cell through the beam corresponding to the at least one uplink transmission channel, without trying to use each transmitting beam to send a signal in turn, and then determining the transmitting beam with a higher matching degree with the receiving beam of the target cell, resulting in a problem of larger access delay.

Optionally, in some embodiments, the measured signal is also used by the target cell to determine a beam corresponding to at least one uplink transmission channel of the target cell.

That is to say, the target cell can not only determine the beam corresponding to at least one uplink transmission channel of the terminal device based on the measured signal (the beam is a transmitting beam for uplink transmission), but also determine the beam corresponding to at least one uplink transmission channel of the target cell (the beam is a receiving beam for uplink transmission). The above-mentioned transmitting beam and receiving beam are beams with a high degree of matching, so that the target cell can use the beam corresponding to at least one uplink transmission channel of the target cell, and the terminal device can use the beam corresponding to at least one uplink transmission channel of the terminal device for uplink transmission, thereby improving the uplink transmission performance.

Optionally, in some embodiments, the identification information of the beam corresponding to the at least one uplink transmission channel of the terminal device includes a beam identifier or number of the beam corresponding to the at least one uplink transmission channel of the terminal device;

The resource information used to transmit the at least one uplink transmission channel includes at least one of the following:

Information on time domain resources used to transmit the at least one uplink transmission channel and information on frequency domain resources used to transmit the at least one uplink transmission channel.

Optionally, in some embodiments, the measured signal is a signal periodically sent by the terminal device.

Specifically, if the terminal device is periodically sending a first signal, the source cell can also determine the configuration information of the measured signal based on the information of the first signal, that is, the signal being sent by the terminal device can be used as the measured signal for measurement in the target cell.

Specifically, if the terminal device is periodically sending a first signal, the source cell can also determine the configuration information of the measured signal based on the information of the first signal, that is, the signal being sent by the terminal device can be used as the measured signal for measurement in the target cell.

The transmission mode of the measured signal may include periodic transmission, non-periodic transmission, or triggered transmission.

For inter-site handover based on the X2 port, the source cell and the target cell negotiate the configuration information of the measured signal, or the target cell sends a first notification message to the source cell, which can be performed in S305 and S307 shown in Figure 3. That is, the source cell and the target cell can negotiate the configuration information of the measured signal through a handover request message and a handover request confirmation message, or the first notification message can be a handover request confirmation message. The source cell sends a notification message to the terminal device in S308 shown in Figure 3, that is, the notification message can be an RRC connection reconfiguration message. Or for inter-site handover based on the S1 port, the source cell and the target cell negotiate the configuration information of the measured signal in some steps of S405, S406, S408 and S409 shown in Figure 4.
