Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a beam-based transmission control method and a beam-based transmission control device.
Background
In New Radio (NR) technology, which is a New Radio technology of the fifth generation mobile communication technology (5G), when signals are transmitted using high frequencies, transmission path penetration loss and the like are large, and a coverage area is small. In order to improve the coverage, the 5G communication generally adopts a transmission method of multiple beams (beams) to improve the signal strength, that is, all the transmission powers are concentrated on one beam at the same time, and one beam only covers one direction. For example, if a beam is used to cover 360 degrees in 4 different units of time, the beam only needs to cover 90 degrees in each unit of time, so that the coverage radius can be increased.
Currently, a single beam-based transmission mode, that is, an omni-directional transmission mode, can simultaneously cover the whole direction, but the coverage radius of each direction is small. The coverage radius of a multi-beam based transmission mode is large, but each beam needs to poll at different time, which brings a certain time delay. Therefore, how to select a suitable transmission method becomes a problem to be solved urgently at present.

Fig. 1 is a flowchart illustrating a beam-based transmission control method according to an embodiment of the present invention. As shown in fig. 1, the beam-based transmission control method according to the embodiment of the present invention specifically includes steps S101 to S103.
S101, the first equipment acquires measurement information between the first equipment and the second equipment.
Specifically, the first device obtains measurement information between the first device and the second device, where the measurement information includes distance information and/or received signal strength of a reference signal. In the embodiment of the present invention, the first device may be a base station or a user terminal, and the second device may be a base station or a user terminal, that is, when the first device is a base station, the second device may be a base station or a user terminal; when the first device is a user terminal, the second device may be a base station or a user terminal. The measurement information in the present example includes distance information and/or received signal strength of a reference signal. Taking the first device as a base station and the second device as a user equipment as an example, the base station may obtain measurement information between the base station and the user equipment, for example, distance information between the base station and the user equipment. In the embodiment of the present invention, the reference signal is sent by the second device, and after receiving the reference signal, the first device may determine the received signal strength of the reference signal.
S102, the first equipment selects a signal transmission mode corresponding to the measurement information.
Specifically, the first device selects a signal transmission mode corresponding to the measurement information. In the embodiment of the present invention, two selection modes may be included: the first method is that a single beam signal transmission mode and/or a multi-beam signal transmission mode are/is selected according to the measurement information, and when the multi-beam signal transmission mode is adopted for signal transmission, the width of a beam signal corresponding to the measurement information and the number of beams scanned at the same time are selected; second, when signal transmission fails during signal transmission using a single beam signal transmission method, the signal transmission is performed using a multi-beam signal transmission method, and the width of the beam signal corresponding to the measurement information and the number of beams scanned at the same time are selected. In the first mode, the first device may compare the measurement information with a preset threshold range, select a corresponding signal transmission mode, and select a width of a beam signal corresponding to the measurement information and a beam number of simultaneous scanning when the signal transmission mode of multiple beams is adopted for signal transmission. In the embodiment of the invention, the width of the beam signal is the coverage angle of the beam signal, and the number of beams scanned at the same time is the number of beams which are simultaneously transmitted.
And S103, the first equipment adopts the signal transmission mode to carry out signal transmission.
Specifically, the first device performs signal transmission by using the signal transmission method. For example, the user terminal, as the first device, may transmit the random access preamble in the selected signaling scheme. As another example, the base station may transmit a paging message using the selected signaling scheme as the first device.
In the embodiment of the invention, the first device acquires the measurement information between the first device and the second device, the measurement information comprises distance information and/or the received signal strength of the reference signal, then selects the signal transmission mode corresponding to the measurement information, finally adopts the signal transmission mode to carry out signal transmission, and selects the proper signal transmission mode to carry out signal transmission through the acquired measurement information, thereby being beneficial to improving the signal transmission quality and reducing the time delay.
Fig. 2 is a flowchart illustrating another beam-based transmission control method according to an embodiment of the present invention. As shown in fig. 2, another beam-based transmission control method according to the embodiment of the present invention specifically includes steps S201 to S204.
S201, the first device transmits signals in a single beam signal transmission mode.
Specifically, in the embodiment of the present invention, the first device is a base station or a user terminal; the second device is a base station or a user terminal. The first device may first use a single beam signal transmission mode, that is, omni-directional antenna transmission, and the number of transmission times may be preset, for example, the number of transmission times is set to 1 or 2, and if the single beam transmission mode fails to transmit within a preset number of times, a multi-beam signal transmission mode is used for signal transmission, and corresponding transmission parameters are set. For example, the first device is a ue, and the ue sends a random access code, or the first device is a base station, and the base station sends a paging message. For the first device, if the first device can transmit the random access code or the paging message in the single beam signal transmission mode and can successfully transmit the random access code or the paging message, the time delay caused by using the multiple beam signal transmission mode can be avoided.
Optionally, in the embodiment of the present invention, the following transmission may be used to transmit without considering the complexity of the device: firstly, the transmission is carried out by adopting a single beam mode, if the transmission fails, the beam width is reduced, for example, the width is changed by covering 360 degrees, 180 degrees and 90 degrees … … degrees, 1 degree, until the beam width is adopted to ensure the successful signal transmission.
S202, the first equipment acquires measurement information between the first equipment and the second equipment.
Specifically, the first device obtains measurement information between the first device and the second device, where the measurement information includes distance information and/or received signal strength of a reference signal. When the measurement information is the received signal strength of the reference signal, the measurement information can be acquired by the following method: the first device receives the reference signal sent by the second device, and then determines the received signal strength of the reference signal according to the received power of the reference signal. In this embodiment of the present invention, if the first device is a user equipment and the second device is a base station, the Reference Signal may be one or a combination of multiple types, such as a Cell Reference Signal (CRS), a Channel State Information Reference Signal (CSI-RS), a Discovery Reference Signal (DRS), a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS), and the like, which are transmitted by the base station. If the first device is a base station and the second device is a user equipment, the Reference Signal may be one or a combination of multiple types, such as a DeModulation Reference Signal (DMRS) and a Sounding Reference Signal (SRS), which are sent by the user equipment. If the first device and the second device are both user terminals, the reference signal may be a reference signal related to the Sidelink, such as one or more combinations of a Sidelink synchronization signal (Sidelink synchronization signals), a Physical Sidelink Discovery Channel (PSDCH), a Sidelink Demodulation reference signal (Sidelink Demodulation reference signals), and the like.
If the measurement information is distance information, the measurement information can be acquired in the following manner: the first device receives the reference signal and the broadcast information sent by the second device, and determines the distance information between the first device and the second device according to the receiving power of the reference signal and the sending power of the reference signal contained in the broadcast information. For example, if the first device is a ue, the second device is a base station, the reference signal may be one or a combination of multiple types of CRS, CSI-RS, DRS, PSS/SSS transmitted by the base station, and the Broadcast Information, that is, the Broadcast Information including the transmission power of the reference signal of the base station, transmitted by the base station may be included in a main system module (Master Information block, MIB) and a System Information Block (SIB) of a Physical Broadcast Channel (PBCH). For another example, if the first device and the second device are both user terminals, the reference signal may be a reference signal related to the Sidelink, such as one or a combination of multiple types of Sidelink synchronization signals, PSDCH, Sidelink demodulation reference signals, and the like, and the Broadcast information is a Physical Sidelink Broadcast Channel (Physical Sidelink Broadcast Channel) and includes the reference signal transmission power of the user terminal.
Optionally, if the measurement information is distance information, the base station may receive a random access request sent by the user terminal, where the random access request carries the distance information between the base station and the user terminal. Or, the base station may receive an uplink scheduling request sent by the user terminal, where the uplink scheduling request carries distance information between the base station and the user terminal.
S203, if the signal transmission fails, the first device transmits signals in a multi-beam signal transmission mode, and selects the width of beam signals corresponding to the measurement information and the quantity of beams scanned at the same time.
Specifically, if the signal transmission fails, the first device performs signal transmission by using a multi-beam signal transmission mode, and selects the width of the beam signal corresponding to the measurement information and the number of beams scanned at the same time. The width of the beam signal is the coverage angle of the beam signal, and the number of beams scanned at the same time is the number of beams simultaneously transmitting signals.
And S204, the first equipment adopts the signal transmission mode to carry out signal transmission.
Specifically, the first device performs signal transmission by using the signal transmission method. For example, the user terminal, as the first device, may transmit the random access preamble in the selected signaling scheme. As another example, the base station may transmit the paging message in the selected signaling scheme as the first device.
In the embodiment of the invention, a first device performs signal transmission by adopting a single beam signal transmission mode, then obtains measurement information between the first device and a second device, wherein the measurement information comprises distance information and/or received signal strength of a reference signal, if the signal transmission fails, the first device performs signal transmission by adopting a multi-beam signal transmission mode, selects the width of a beam signal corresponding to the measurement information and the quantity of beams scanned at the same time, and finally performs signal transmission by adopting the signal transmission mode, and selects a proper signal transmission mode to perform signal transmission by using the obtained measurement information, thereby being beneficial to improving the signal transmission quality and reducing the time delay.

Specifically, if the distance information D1 is not less than D1 and less than D2, the distance information belongs to a fifth preset threshold range, the first device preferentially selects a single beam signal transmission mode, if the signal transmission is successful, the transmission mode is not selected, otherwise, the signal transmission fails, and the first device further selects a multi-beam signal transmission mode and selects the width of the beam signal corresponding to the distance information and the number of beams scanned at the same time. In the embodiment of the invention, the transmission times can be preset while the single beam signal transmission mode is selected, and after the preset transmission is achieved, the multi-beam signal transmission mode is further selected. The width of the beam signal is the coverage angle of the beam signal, and the number of beams scanned at the same time is the number of beams simultaneously transmitting signals.
S306, if the distance information belongs to a sixth preset threshold range, the first equipment selects a multi-beam signal transmission mode, and selects the width of beam signals corresponding to the distance information and the quantity of beams scanned at the same time.
Specifically, if the distance information D1 is greater than or equal to D2, the distance information belongs to a sixth preset threshold range, the first device has multiple beam signal transmission modes, and selects the width of the beam signal corresponding to the distance information and the number of beams scanned at the same time.
And S307, the first equipment adopts the signal transmission mode to carry out signal transmission.
Specifically, the first device performs signal transmission by using the signal transmission method. For example, the user terminal, as the first device, may transmit the random access preamble in the selected signaling scheme. As another example, the base station may transmit the paging message in the selected signaling scheme as the first device.
