[0040] Embodiments of the present disclosure are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0041] Power control is an important element in communication systems. By using appropriate power, uplink capacity can be increased, power consumption of mobile phones can be reduced, and uplink interference to neighboring cells can be reduced. Path loss value (PL) is an important factor affecting the uplink power of each channel. A clear path loss value is required to further calculate the power value of each uplink channel. In related technologies, multi-antenna transmission schemes all use the same power value. For different path losses on each antenna, the normalization strategy used is:

[0042] 1. Take the instantaneous maximum value of the line loss of each antenna as the path loss value of all antennas to calculate the transmit power of the uplink channel. This can increase the transmit power, improve the transmission performance, and increase the demodulation accuracy on the base station side;

[0043] 2. Take the instantaneous minimum value of the line loss of each antenna as the path loss value of all antennas to calculate the transmit power of the uplink channel. This can reduce the transmit power, reduce power consumption, and enhance the battery life of the mobile phone;

[0044] 3. Take the instantaneous average value of the line loss of each antenna as the path loss value of all antennas to calculate the transmit power of the uplink channel. This can enhance the transmit power of some antennas and save power consumption to a certain extent.

[0045] 4. Taking the long-term smoothed value of each antenna's path loss as the path loss value of all antennas to calculate the transmit power of the uplink channel can enhance the transmit power of some antennas, while saving power consumption to a certain extent and reducing the possibility of power mutation.

[0046] For the above four processing methods, no matter which one is used, each antenna uses the same transmission power in the end, and it is impossible to perform differentiated processing for different path loss values ​​of the antenna. For antennas with smaller path loss, a smaller transmission power could have been used, but due to policy restrictions, a larger power is required to transmit, which increases power consumption; for antennas with larger path loss, a larger transmission power should have been used, but due to policy restrictions, a smaller power is used to transmit, affecting the demodulation performance on the base station side. When the difference is large, the impact is more serious, which is manifested as insufficient mobile phone battery or uplink transmission failure.

[0047] In summary, in order to solve the technical problems in the related art, the embodiment of the present disclosure provides a power determination method, by determining a first measurement value and a second measurement value; according to the first measurement value and the second measurement value, respectively determining a first power corresponding to the first antenna and a second power corresponding to the second antenna; at the first power, sending an uplink channel and / or a signal to the network device through the first antenna, and / or, at the second power, sending an uplink channel and / or a signal to the network device through the second antenna. By independently estimating and saving the measurement value of each antenna, the optimal transmission power can be calculated for each transmitting antenna, thereby reducing power consumption while ensuring performance.

[0048] The power determination method provided in the present application will be described in detail below with reference to the accompanying drawings.

[0049] Figure 1 FIG. 1 is a flow chart of a power determination method proposed in an embodiment of the present disclosure. Figure 1 As shown, the method can be executed by a terminal. The method can include the following steps.

[0050] Step 101: determine a first measurement value and a second measurement value.

[0051] In the embodiment of the present disclosure, the terminal supports at least the first antenna and the second antenna. Exemplarily, supporting the first antenna and the second antenna indicates that the terminal supports multi-antenna transmission. Exemplarily, the terminal includes two or more antennas.

[0052] In some embodiments, the first measurement value corresponds to a first antenna and the second measurement value corresponds to a second antenna.

[0053] In some embodiments, the number of first antennas and the number of second antennas are not limited. Specifically, there may be multiple first antennas and multiple second antennas, and the measurement values ​​of the multiple first antennas and the multiple second antennas are determined respectively for the subsequent determination of the power of each antenna.

[0054] In some embodiments, the first measurement value is obtained by measuring a first reference signal received by a first antenna, and the second measurement value is obtained by measuring a second reference signal received by a second antenna.

[0055] In some embodiments, the first measurement value and / or the second measurement value includes at least one of the following: Reference Signal Receiving Power (RSRP), Reference Signal Receiving Quality (RSRQ), Received Signal Strength Indication (RSSI), Signal to Interference plus Noise Ratio (SINR), Channel Impulse Response (CIR), Power Delay Profile (PDP), and Delay Profile (DP).

[0056] In the above embodiment, the measurement value obtained by measuring the reference signal may be used for subsequent power calculation and determination of the target antenna, where the target antenna indicates an antenna used to send an uplink channel or signal.

[0057] Step 102: Determine a first power corresponding to the first antenna and a second power corresponding to the second antenna based on the first measurement value and the second measurement value.

[0058] In some embodiments, determining the first power and the second power is calculated based on a power calculation formula specified by a protocol.

[0059] In some embodiments, the power calculation formula is determined according to the type of the reference signal.

[0060] In the above embodiment, different power calculation formulas are determined based on different reference signals, and the power value can be obtained by performing calculations in combination with the data.

[0061] For example, power calculation may be performed based on a corresponding power calculation formula according to the type of uplink channel and / or signal transmitted (PRACH, or PUSCH, or PUCCH, or SRS).

[0062] In some embodiments, the respective powers corresponding to the plurality of first antennas and the respective powers corresponding to the plurality of second antennas may be determined respectively according to the plurality of measurement values.

[0063] Step 103: sending an uplink channel and / or signal through the first antenna at a first power, and / or sending an uplink channel and / or signal through the second antenna at a second power.

[0064] In some embodiments, based on the calculated transmit power of each antenna, after the target antenna is selected, transmission can be performed on the target antenna based on the calculated transmit power, thereby reducing power consumption while ensuring optimal transmit power.

[0065] In some embodiments, the antenna with the largest measurement value may be selected as the target antenna, or the target antenna may be determined by other means, which is not limited by the present disclosure.

[0066] In some embodiments, the target antenna may be one or more of the first antenna and the second antenna, and the target antenna may be all or part of the antennas supported by the terminal. For example, when the first antenna is selected as the target antenna, the uplink channel and / or signal may be sent through the first antenna at a first power. For another example, when the second antenna is selected as the target antenna, the uplink channel and / or signal may be sent through the second antenna at a second power. For another example, when both the first antenna and the second antenna are used as target antennas, the uplink channel and / or signal may be sent through the first antenna at a first power, and the uplink channel and / or signal may be sent through the second antenna at a second power.

[0067] In summary, the above embodiments of the present application determine the first measurement value and the second measurement value; determine the first power corresponding to the first antenna and the second power corresponding to the second antenna respectively according to the first measurement value and the second measurement value; send the uplink channel and / or signal to the network device through the first antenna at the first power, and / or, send the uplink channel and / or signal to the network device through the second antenna at the second power. By independently estimating and saving the measurement value of each antenna, the optimal transmission power can be calculated for each transmitting antenna, thereby reducing power consumption while ensuring performance.

[0068] Figure 2 A flow chart of a method for determining a first measurement value and a second measurement value proposed in an embodiment of the present disclosure. Figure 2 The illustrated embodiment may include the following steps.

[0069] Step 201: receiving a first reference signal sent by a network device through a first antenna, and receiving a second reference signal sent by a network device through a second antenna.

[0070] In some embodiments, the network device may be a base station.

[0071] In some embodiments, the reference signal may be a "downlink reference signal".

[0072] In some embodiments, the reference signal sent by the network device may be one or more.

[0073] In some embodiments, the terminal receives one or more reference signals sent by the network device, and measures each reference signal separately.

[0074] In some embodiments, there may be multiple first antennas and multiple second antennas. For example, multiple first antennas receive first reference signals sent by the network device, and multiple second antennas receive multiple second reference signals sent by the network device.

[0075] Step 202: measure a first reference signal and a second reference signal respectively to obtain a first measurement value and a second measurement value.

[0076] In some embodiments, the first measurement and the second measurement are used to determine the target antenna.

[0077] In some embodiments, a plurality of first measurement values ​​may be obtained by measuring first reference signals received by a plurality of first antennas, and a plurality of second measurement values ​​may be obtained by measuring second reference signals received by a plurality of second antennas.

[0078] In the embodiment of the present disclosure, by measuring the reference signal, a first measurement value and / or a second measurement value is obtained, which can be used to subsequently calculate the power of different antennas, respectively, so as to determine the target antenna for uplink transmission.

[0079] In summary, a first reference signal sent by a network device is received through a first antenna, and a second reference signal sent by a network device is received through a second antenna, and the first reference signal and the second reference signal are measured respectively to obtain a first measurement value and a second measurement value, which can be used to subsequently determine the path loss and power of different antennas respectively, and can avoid extra power consumption caused by each antenna using the same transmission power or insufficient power of the mobile phone or uplink transmission failure.

[0080] Figure 3 A flow chart of a method for determining a first power and a second power according to a first path loss value and a second path loss value proposed in an embodiment of the present disclosure. Figure 3 The illustrated embodiment includes the following steps:

[0081] Step 301: Determine a first path loss value corresponding to a first antenna and a second path loss value corresponding to a second antenna according to a first measurement value and a second measurement value.

[0082] In some embodiments, the path loss value may be used to calculate the power value of the corresponding antenna.

[0083] In some embodiments, a plurality of first path loss values ​​corresponding to a plurality of first antennas and a plurality of second path loss values ​​corresponding to a plurality of second antennas may be determined based on a plurality of first measurement values ​​and a plurality of second measurement values, wherein the measurement values ​​and the path loss values ​​are in one-to-one correspondence.

[0084] In some embodiments, see Figure 4 The illustrated embodiment may use other related methods to calculate the path loss value based on the measured value, which will not be described in detail in this embodiment.

[0085] Step 302: Determine a first power and a second power according to the first path loss value and the second path loss value respectively.

[0086] In some embodiments, the corresponding multiple first powers and multiple second powers may be determined based on multiple first path loss values ​​corresponding to multiple first antennas and multiple second path loss values ​​corresponding to multiple second antennas, wherein the antennas and the powers are in a one-to-one correspondence.

[0087] In the embodiments of the present disclosure, the power corresponding to the antenna can be further calculated by calculating the path loss value, thereby determining the corresponding power of each antenna.

[0088] For example, the power calculation may be performed based on the corresponding power calculation formula according to the type of uplink channel and / or signal to be sent (PRACH, PUSCH, PUCCH, or SRS). In summary, the first measurement value corresponding to the first antenna and the second measurement value corresponding to the second antenna are based on Figure 4 The illustrated embodiment or other related methods may be used to calculate the path loss value, determine the first path loss value corresponding to the first antenna, and the second path loss value corresponding to the second antenna, which can be used to subsequently determine the first power and the second power respectively, thereby determining the power value corresponding to each antenna, and avoiding using the same power for transmission when selecting an antenna for transmission, resulting in additional power consumption or insufficient mobile phone battery or uplink transmission failure.

[0089] Figure 4 A flow chart of a method for determining a first path loss value and a second path loss value proposed in an embodiment of the present disclosure. Figure 4 The illustrated embodiment includes the following steps:

[0090] Step 401: Acquire reference signal energy sent by a network device.

[0091] In some embodiments, the reference signal energy may be a reference signal energy sent by a base station as a benchmark reference value.

[0092] In some embodiments, the reference signal energy may be a setting value in a radio resource control (RRC) parameter, for example, 10 dBm.

[0093] In some embodiments, the reference signal energy may be sent simultaneously with the reference signal or before sending the reference signal.

[0094] Step 402: Determine a first difference between a reference signal energy and a first measurement value and a second difference between a reference signal energy and a second measurement value.

[0095] In some embodiments, the difference between the reference signal energy and the measured value is the path loss value.

[0096] For example, when the measured value is 8 dBm, the difference between the reference signal energy and the measured value is 2 dBm, and the path loss value of the antenna is 2 dBm.

[0097] In some embodiments, the first measurement value and the second measurement value may be multiple. Specifically, the differences between the reference signal energy and the multiple first measurement values ​​and the multiple second measurement values ​​may be determined respectively to obtain multiple first difference values ​​and multiple second difference values.

[0098] Step 403: determine the first difference as a first path loss value, and determine the second difference as a second path loss value.

[0099] In some embodiments, the first difference may be multiple, and the second difference may be multiple. Specifically, the multiple first difference values ​​correspond to the multiple first antennas, that is, the multiple first difference values ​​are the first path loss values ​​corresponding to the multiple first antennas, and the multiple second difference values ​​correspond to the multiple second antennas, that is, the multiple second difference values ​​are the second path loss values ​​corresponding to the multiple second antennas.

[0100] In summary, the reference signal energy sent by the obtained network device is used as the benchmark reference value. Figure 2 The difference between the first measurement value and / or the second measurement value determined in the calculation and the benchmark reference value is used as the path loss value, and the path loss of each antenna when transmitting data can be obtained, which is used for the subsequent calculation of the power corresponding to the antenna, so as to avoid using the same power for transmission when selecting the antenna for transmission, resulting in additional power consumption or insufficient mobile phone power or uplink transmission failure.

[0115] Step 502: Determine a first power and a second power respectively according to the first path loss value, the second path loss value, and communication parameters corresponding to the type.

[0116] In some embodiments, the first path loss value is a first difference between the reference signal energy and the first measurement value, and the second path loss value is a second difference between the reference signal energy and the second measurement value.

[0117] In some embodiments, the type is the type of uplink channel and / or signal to be sent. For example, the type can be a random access channel and / or signal (Physiacal Random Access Channel, PRACH), an uplink shared channel and / or signal (Physical Uplink Shared Channel, PUSCH), an uplink control channel and / or signal (Physical Uplink Control Channel, PUCCH), and an uplink reference signal (Sounding reference signal, SRS).
