In order to solve the above existing problems, the present disclosure provides a method, an apparatus, a storage medium, and an electronic device for determining a communication resource, where access request information sent by a first device (e.g., an IAB device) may be received by a network device (e.g., a base station), and then a first reference signal is sent to the first device according to identification information of the first device carried in the access request information, and the network device sends the first reference signal to the first device through at least one first preset beam, where identifications or sequences of first reference signals sent on different first preset beams are different, and then the first device may measure a reception strength of the first reference signal sent by each received first preset beam and return the reception strength to the network device, so that the network device may determine a communication beam (generally including a sending beam and a receiving beam) of the network device according to the reception strength, that is, and determine an optimal transmission beam of the communication beam of the network device according to the measurement result of the reception strength of the first reference signal sent by the first device, so that an optimal transmission efficiency of the communication beam of the network device may be matched, and thus data transmission efficiency may be achieved.
Specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.
Fig. 1 is a flowchart illustrating a method for determining communication resources, applied to a network device (e.g., a base station), according to an exemplary embodiment, and the method includes the following steps:
in step 101, access request information sent by a first device is received, where the access request information includes identification information of the first device.
The first device may include an IAB device, and the access request information may further include a number of preset receiving beams of the first device, a number of second preset transmitting beams of the first device, and beam indication information indicating whether the transmitting beam and the receiving beam of the first device have correlation.
The correlation here means that the transmission beam and the reception beam have a correspondence relationship, that is, if the transmission beam and the reception beam of the first device have a correlation, it can be understood that when the transmission beam of the first device is determined, the reception beam of the first device corresponding to the transmission beam can be directly determined based on the correspondence relationship between the transmission beam and the reception beam, and accordingly, when the reception beam of the first device is determined, the transmission beam of the first device corresponding to the reception beam can be directly determined based on the correspondence relationship between the transmission beam and the reception beam.
In step 102, a first reference signal is transmitted to the first device through at least one first preset beam, so that the first device measures the received strength of the first reference signal.
The identifiers or sequences of the first reference signals sent on different first preset beams are different, the first preset beams are preset sending beams of the network device, and the first reference signals carry reference signal identifiers corresponding to the first preset beams for sending the first reference signals, that is, the identifiers of the first reference signals and the identifiers of the first preset beams have a one-to-one correspondence relationship.
In step 103, response information sent by the first device is received, where the response information includes the received strength measured by the first device for each first reference signal and a corresponding first reference signal identifier.
In step 104, a communication beam of the network device is determined according to the reception strength.
In this step, a first preset beam corresponding to the first reference signal with the highest reception intensity may be determined as a first transmission beam used by the network device to transmit a signal to the first device.
In addition, the communication beam further includes a first receiving beam, and generally, the beam of the transmission signal of the network device and the beam of the reception signal have a one-to-one correspondence relationship, so after the first transmission beam is determined, the first receiving beam corresponding to the first transmission beam can be determined according to a preset correspondence relationship, where the preset correspondence relationship is a correspondence relationship between the beam of the reception signal of the network device and the beam of the transmission signal.
By adopting the method, the network equipment can determine the communication beam of the network equipment according to the measurement result of the first equipment on the receiving intensity of the first reference signal sent based on different first preset beams, so that the network equipment can adopt the best communication beam with the highest receiving intensity of the transmitted reference signal to perform data transmission matching, thereby realizing the best state of data transmission and also effectively improving the transmission efficiency of data.
Fig. 2 is a flowchart illustrating a method for determining communication resources, applied to a first device (e.g., an IAB device), according to an example embodiment, and shown in fig. 2, the method includes the following steps:
in step 201, access request information is sent to the network device, where the access request information includes identification information of the first device.
The network device may be a base station, and the access request information may further include a number of preset receiving beams of the first device, a number of second preset transmitting beams of the first device, and beam indication information used for indicating whether the transmitting beam and the receiving beam of the first device have correlation, where the second preset transmitting beam is a transmitting beam supported by the first device and preset for the first device.
The correlation here means that the transmission beam and the reception beam have a correspondence relationship, that is, if the transmission beam and the reception beam of the first device have a correlation, it can be understood that when the transmission beam of the first device is determined, the reception beam of the first device corresponding to the transmission beam can be directly determined based on the correspondence relationship between the transmission beam and the reception beam, and accordingly, when the reception beam of the first device is determined, the transmission beam of the first device corresponding to the reception beam can be directly determined based on the correspondence relationship between the transmission beam and the reception beam.
In step 202, a first reference signal sent by the network device information through at least one first preset beam is received, where the identities or sequences of the first reference signals sent on different first preset beams are different.
The first preset beam is a preset transmission beam of the network device, and the first reference signal carries a reference signal identifier corresponding to the first preset beam for transmitting the first reference signal, that is, the identifier of the first reference signal and the identifier of the first preset beam have a one-to-one correspondence relationship.
In step 203, the receiving strength of the first reference signal is measured, and response information is sent to the network device, where the response information includes the receiving strength measured by the first device for each first reference signal and a corresponding first reference signal identifier, so that the network device determines a communication beam of the network device according to the receiving strength.
The communication beam includes a first transmission beam and a first reception beam, the first transmission beam may be an optimal transmission beam corresponding to a reference signal with the highest reception intensity among reference signals transmitted by the network device, and the first reception beam may be an optimal reception beam for the network device to receive signals optimally.
By adopting the method, the first device can measure the receiving intensity of the first reference signal sent by the network device by adopting different first preset beams, so that the network device can determine the first sending beam and the first receiving beam of the network device based on the measurement result, and the network device can adopt the best communication beam with the highest receiving intensity of the transmitted reference signal to carry out data transmission matching, thereby realizing the best state of data transmission and also effectively improving the transmission efficiency of data.
Fig. 3 is a flow chart illustrating a method of determining communication resources according to an exemplary embodiment, as shown in fig. 3, the method including the steps of:
in step 301, a first device sends access request information to a network device, where the access request information includes identification information of the first device.
The first device may be an IAB device, the network device may be a base station, and when the first device initially accesses the network device, the access request information may be sent to the network device, and the access request information may further include the number of second preset transmission beams of the first device, and beam indication information used for indicating whether a transmission beam and a reception beam of the first device have correlation, where the second preset transmission beam is a transmission beam supported by the first device and preset for the first device.
The correlation here means that the transmission beam and the reception beam have a correspondence relationship, that is, if the transmission beam and the reception beam of the first device have a correlation, it can be understood that when the transmission beam of the first device is determined, the reception beam of the first device corresponding to the transmission beam can be directly determined based on the correspondence relationship between the transmission beam and the reception beam, and accordingly, when the reception beam of the first device is determined, the transmission beam of the first device corresponding to the reception beam can be directly determined based on the correspondence relationship between the transmission beam and the reception beam.
In this step, in the process that the first device sends the access request information to the network device, one transmission beam may be randomly selected from the second preset transmission beams supported by the first device to send the access request information, or multiple second preset transmission beams supported by the first device may be polled to send the access request information.
In addition, after receiving the access request message, the network device may return access response information to the first device, so that the first device establishes a connection with the network device, where the access response information may be that the network device randomly selects one of the transmission beams supported by the network device to transmit.
In step 302, the network device transmits a first reference signal to the first device through at least one first preset beam according to the identification information of the first device.
The identifiers or sequences of the first reference signals sent on different first preset beams are different, the first preset beams are preset sending beams of the network device, and the first reference signals carry reference signal identifiers corresponding to the first preset beams for sending the first reference signals, that is, the identifiers of the first reference signals and the identifiers of the first preset beams have a one-to-one correspondence relationship.
For example, if the first preset beam of the network device includes three beams, i.e., beam 1, beam 2, and beam 3, the network device may send an a reference signal to the first device through beam 1, send a b reference signal to the first device through beam 2, and send a c reference signal to the first device through beam 3, where the a reference signal carries a reference signal identifier a corresponding to beam 1, the b reference signal carries a reference signal identifier b corresponding to beam 2, and the c reference signal carries a reference signal identifier c corresponding to beam 3.
Since different beams have different signal coverage angles, in this embodiment, an optimal transmission beam may be determined for the network device in a plurality of the first preset beams by performing steps 303 to 304, so that the network device may perform data transmission through the optimal transmission beam, thereby improving data transmission efficiency.
In step 303, the first device measures the received strength of the first reference signal and sends response information to the network device, where the response information includes the received strength measured by the first device for each first reference signal and a corresponding first reference signal identifier.
It should be noted that, in order to facilitate comparison of the received strengths of the first reference signals transmitted by different first preset beams, the initial signal strengths of the different first reference signals are the same before the first reference signals are transmitted by the different first preset beams, for example, continuing to take the example in step 302, assuming that the initial signal strength of the a reference signal is a1 before the a reference signal is transmitted to the first device through the beam 1, the initial signal strength of the b reference signal is b1 before the b reference signal is transmitted to the first device through the beam 2, the initial signal strength of the c reference signal is c1 before the c reference signal is transmitted to the first device through the beam 3, then a1= b1= c1, but after the first device receives the a reference signal, the b reference signal and the c reference signal respectively, since the three reference signals are transmitted by different first preset beams respectively, and since the signal coverage angles of the different beams are also different, the first device determines that the received strengths of the different first reference signals are the same.
In step 304, the network device determines a first preset beam corresponding to the first reference signal with the highest receiving strength as a first transmission beam used by the network device to transmit a signal to the first device.
The first transmission beam may be an optimal transmission beam corresponding to a reference signal with the highest reception intensity among the reference signals transmitted by the network device.
For example, continuing with the example in step 303, a1 is the initial signal strength of the a reference signal, b1 is the initial signal strength of the b reference signal, and c1 is the initial signal strength of the c reference signal, after the network device transmits the a reference signal to the first device through the beam 1, the first device measures the reception strength of the a reference signal as a2, after the network device transmits the b reference signal to the first device through the beam 2, the first device measures the reception strength of the b reference signal as b2, after the network device transmits the c reference signal to the first device through the beam 3, the first device measures the reception strength of the c reference signal as c2, (due to the existence of the signal attenuation problem, a1 > a2, b1 > b2, and c1 > c 2), at this time, the network device may receive the reception strengths of the three reference signals transmitted by the first device, and if the network device determines that a2 > b2 > c2, it may determine that the first reference signal with the highest reception strength is the first reference signal, and thus, this example may be a beam, and this may not be a beam.
In step 305, the network device determines a first receiving beam corresponding to the first transmitting beam according to a preset correspondence.
The preset corresponding relationship is a corresponding relationship between a beam of the network device for receiving signals and a beam of the network device for transmitting signals, and the first receiving beam can be an optimal receiving beam for the network device for receiving signals.
Generally, beams of transmission signals of a network device have a one-to-one correspondence relationship with beams of reception signals, and therefore, after the first transmission beam of the network device is determined through performing steps 301 to 304, the first reception beam of the network device corresponding to the first transmission beam can be determined according to the preset correspondence relationship through performing this step.
In step 306, the network device transmits a first preset number of second reference signals to the first device through the first transmission beam.
The first preset number is not less than the number of preset receiving beams of the first device, so that the first device determines a second receiving beam of the first device in a plurality of the preset receiving beams according to the second reference signal.
In addition, the access request information further includes the number of preset receiving beams of the first device, so that after the network device determines the first sending beam with the best sending signal quality, a first preset number of second reference signals may be sent to the first device through the first sending beam, so that the first device may determine a second receiving beam of the first device in a plurality of preset receiving beams according to the second reference signals, where the second receiving beam is an optimal receiving beam of the first device with the best receiving signal quality, and the first preset number is not less than the number of preset receiving beams, so that it may be ensured that each of the preset receiving beams of the first device may receive the second reference signal.
In step 307, the first device receives, through at least one preset receive beam, a second reference signal transmitted by the network device through the first transmit beam.
Wherein, the initial signal strengths of the plurality of second reference signals transmitted by the network device are all the same.
In step 308, the first device performs signal strength measurement on the second reference signal received by each preset receiving beam, and determines that the preset receiving beam corresponding to the target reference signal with the highest received signal strength is the second receiving beam.
For example, assuming that the first device supports 3 preset receive beams, which are the receive beam x, the receive beam y, and the receive beam z, respectively, if the first device determines that the signal strength of the second reference signal received by the receive beam x and transmitted by the network device is x1, determines that the signal strength of the second reference signal received by the receive beam y and transmitted by the network device is y1, determines that the signal strength of the second reference signal received by the receive beam z and transmitted by the network device is z1, and x1 < y1 < z1, it may be determined that the signal strength of the second reference signal received by the receive beam z is the highest, so that the first device may determine the receive beam z of the 3 preset receive beams as the second receive beam of the first device.
In addition, it has already been mentioned above that the access request information may further include the number of second preset transmission beams of the first device and beam indication information used for indicating whether the transmission beam and the reception beam of the first device have a correlation, the explanation of the correlation has already been described in step 301, which is not described herein again, and after step 308 is executed, the optimal reception beam of the first device (i.e., the second reception beam) may be determined, but if the network device determines that the transmission beam and the reception beam of the first device do not have a correlation according to the beam indication information, it is described that the transmission beam and the reception beam of the first device do not have a corresponding relationship, that is, the optimal transmission beam of the first device cannot be determined by the second reception beam, in this case, in this embodiment, the transmission beam (i.e., the second transmission beam) of the first device may be determined optimally by performing steps 309 to 311.
In step 309, if it is determined that the transmission beam and the reception beam of the first device do not have correlation according to the beam indication information, the network device transmits uplink reference signal configuration information to the first device.
The uplink reference signal configuration information includes a second preset number of uplink reference signals, where the second preset number is not less than the number of the second preset transmission beams of the first device, and the uplink reference signal configuration information may include SRS configuration information.
In step 310, the first device sends uplink reference signals to the network device through at least one second preset sending beam according to the uplink reference signal configuration information.
The uplink reference signal may include an SRS signal, and the uplink reference signal carries identification information corresponding to a second preset transmission beam, where the first device transmits the uplink reference signal.
In step 311, the network device determines, among the second preset transmission beams, that the beam for transmitting the target uplink reference signal is the second transmission beam of the first device, and transmits the identification information of the second transmission beam to the first device.
The target uplink reference signal is an uplink reference signal with the highest reception strength received by the network device.
For example, assuming that the first device supports 3 second preset transmission beams, which are a transmission beam h, a transmission beam j and a transmission beam k, respectively, and the first device transmits an uplink reference signal n1 to the network device through the transmission beam h, transmits an uplink reference signal n2 to the network device through the transmission beam j, and transmits an uplink reference signal n3 to the network device through the transmission beam k, after the network device receives the three uplink reference signals, the network device may measure the received strength of each received uplink reference signal, so that the second preset transmission beam corresponding to the target uplink reference signal with the highest transmission strength may be selected as the second transmission beam, for example, if the network device measures that the reception strength of the uplink reference signal n1 is m1, the reception strength of the uplink reference signal n2 is m2, the reception strength of the uplink reference signal n3 is m3, and m2 > m1 > m3, the uplink reference signal n2 may be determined as the target uplink reference signal, and the network device may further determine that the transmission beam j corresponding to the uplink reference signal n2 is the second transmission beam, which is not limited by the foregoing examples.
In step 312, the first device determines the second transmission beam based on the identification information of the second transmission beam.
After determining the second transmission beam, the network device may send the determined identification information of the second transmission beam to the first device, so that the first device may determine an optimal transmission beam (i.e., the second transmission beam) among a plurality of second preset transmission beams according to the identification information of the second transmission beam.
To this end, the optimal transmit beam (i.e., the first transmit beam) and the optimal receive beam (i.e., the first receive beam) of the network device, and the optimal transmit beam (i.e., the second transmit beam) and the optimal receive beam (i.e., the second receive beam) of the first device are determined.
By adopting the method, the network device may determine, according to a measurement result of the first device on the reception intensity of the first reference signal transmitted based on different first preset beams, a first transmission beam of the network device, and further determine a first reception beam of the network device corresponding to the first transmission beam, and the network device may further determine, for the first device, a second transmission beam in the second preset transmission beam based on uplink reference signals respectively transmitted by the first device through a plurality of second preset transmission beams under the condition that it is determined that the transmission beam and the reception beam of the first device do not have correlation.
