For example, when the frequency band used for inter-frequency measurement is a frequency band below 3 GHz, and the reference signal is SS Block, when 15KHz subcarrier spacing is used for transmission, in this case, the maximum transmission of the reference signal The number is 4 and the transmission duration is 2 ms. However, the number of reference signals actually transmitted is 2 and the actually transmitted reference signal is the first time domain at the time domain position of the original 4 reference signals transmitted. For the reference signal transmitted in the position and the second time domain position, the network device can send an indication message to the terminal device. The indication message includes the actual number of transmitted reference signals is 2. The selection rule of the reference signal is to select the original transmitted 4 reference signals The reference signal transmitted in the first time domain position and the second time domain position in the time domain position of the time, at this time, the terminal device can determine that the transmission duration of the transmitted reference signal is 1 ms according to the indication message.

Optionally, the number of reference signals actually acquired by the terminal device in the cell may also be indicated to the terminal device by the network device in the form of bits.

For example, when the frequency band used for inter-frequency measurement is a frequency band below 3 GHz, the reference signal is SS Block, and the 15KHz sub-carrier interval transmission is used. In this case, the maximum number of reference signals is 4 and the transmission duration is 2ms, however, at this time, the actual number of reference signals transmitted is two, and the network device may send a "1100" field to the terminal device, indicating that the terminal device is the first in the time domain position of the original transmission of four reference signals. The reference signal is transmitted in the time domain position and the second time domain position. Through this field, the terminal device can learn that the actually transmitted reference signal occupies the first two time domain positions of the original time domain position of the 4 reference signals. Therefore, The terminal device can determine that the transmission duration of the transmission reference signal is 1 ms; when the field sent by the network device to the terminal device is “0101”, the field indicates that the terminal device is in the time domain position of the original transmission of 4 reference signals. The two time domain positions and the fourth time domain position transmit the reference signal. If the transmission start time of the reference signal carried in the configuration signal of the reference signal is the first time domain position of the time domain position of the original transmission of four reference signals, In this case, the terminal device may determine that the transmission duration of the reference signal is still 2 ms.

Therefore, the terminal device can determine the transmission duration of the reference signal in the cell according to the information such as the number of actually transmitted reference signals, the position of the transmitted reference signal in the time domain, and the information such as the start time of transmitting the reference signal.

It should be understood that the length of the measured GAP may be the first transmission duration, or may be greater than the first transmission duration.

Optionally, in some embodiments, since the cells on the first target measurement frequency point may not be synchronized very accurately, there is a certain error in the transmission time when each cell transmits the reference signal, in order to compensate The influence of the error on the length of the measurement GAP can be determined by adding a time margin to the first transmission duration after the first transmission duration is determined, so as to ensure that the determined measurement GAP can cover the first GAP The transmission duration of reference signals transmitted by all cells on the target measurement frequency.

Optionally, the time margin may be preset, and after the terminal device determines the first transmission duration according to the configuration message of the reference signal, adding the preset time margin to the first transmission duration may be obtained Measure the length of GAP.

Optionally, the time margin can also be determined according to the time synchronization relationship between multiple cells on the first target measurement frequency point.

The time synchronization relationship may include at least symbol-level synchronization and slot-level synchronization. The symbol-level synchronization is a time duration of transmission of a reference signal between every two cells in a plurality of cells differs by one symbol, and slot-level synchronization is The transmission time of the reference signal transmitted between every two cells in the multiple cells differs by one slot.

Optionally, when the time synchronization relationship between cells is symbol-level synchronization, the determined time margin is less than the time margin determined when the time synchronization relationship between cells is slot-level synchronization, for example, between cells When the time synchronization relationship is symbol-level synchronization, the time margin can be determined to be 0.2 ms, and when the time synchronization relationship between cells is slot-level synchronization, the time margin can be determined to be 1 ms.

Optionally, in some embodiments, the terminal device receives a synchronization status indication message sent by the network device, and the synchronization status indication message is used to indicate a time synchronization relationship between multiple cells on the first target frequency point.

Optionally, in some embodiments, the network device may also indicate the time synchronization relationship between the cells to the terminal device in the form of bits. For example, the network device may use a 1-bit field or a 2-bit field. Indicates the time synchronization relationship between cells to the terminal device. The network device can use "0" to indicate that the time synchronization relationship between cells is symbol-level synchronization, and "1" indicates that the synchronization relationship between cells is slot-level synchronization. Or, you can use "00" to indicate that the time synchronization relationship between cells is symbol-level synchronization, "01" indicates that the synchronization relationship between cells is slot-level synchronization, "10" indicates that the cells are not synchronized, and so on.

Optionally, in some embodiments, when multiple cells on the first target measurement frequency point are not synchronized, the measurement GAP may be set to a default of 6 ms.

Therefore, when determining the length of the measurement GAP, you can first determine whether the multiple cells on the first target measurement frequency are synchronized. When the multiple cells are synchronized or approximately synchronized, you can use the configuration information of the reference signal and The time margin determines the length of the measured GAP. When multiple cells are not synchronized, the length of the measured GAP can be directly set to 6 ms.

When the determined length of the measured GAP is less than 6 ms, the terminal device may send or receive data messages at times other than the determined length of the measured GAP, thereby reducing the influence of the measured GAP on data transmission.

When the reference signal includes both SS Block and CSI-RS, when determining the length of the measured GAP, it is necessary to determine whether there is a time interval between the transmission of the SS Block and the transmission of CSI-RS. If there is a time interval, the measurement of the GAP The length should be the sum of the transmission time, the time margin required for transmitting the two reference signals, and the time interval of the two reference signals.

For example, in the cell A on the first measurement target frequency point, according to the configuration information of the reference signal, it is determined that the transmission duration of the transmission reference signal SS Block is T1, and the transmission duration of the transmission reference signal CSI-RS is T2, the reference signal The transmission interval between the SS Block and the reference signal CSI-RS is T0, and the time margin is T3. Assuming that the first measurement target frequency only includes cell A, then it can be determined that the measurement GAP is T1+T2+T3+T0, that is, the length of the GAP needs to cover the reference signal SS Block and the reference signal CSI-RS. When other cells are included on the first measurement target frequency point, the above two of each cell can be calculated separately The transmission duration of the reference signal, and then separately calculate the first transmission duration of the above two reference signals, and determine the sum of the first transmission duration of the above two reference signals and the transmission interval and time margin between the reference signals as Measure the length of GAP.

The above embodiment uses the terminal device to determine the length of the measured GAP according to the configuration information of the reference signal of at least one cell on the first target measurement frequency sent by the network device as an example to explain how to determine the length of the measured GAP. If you directly receive the GAP length measurement message, how to determine the GAP length measurement will be performed by the network device.

The network device may determine the transmission duration of the reference signal of each cell according to the transmission status of the reference signal of each cell on the first target frequency point, and determine the first transmission duration, where the first transmission duration meets the preset The conditional transmission duration, and then according to the first transmission duration, determine the length of the measured GAP, and send the length of the measured GAP to the terminal device.

Optionally, in some embodiments, the configuration information of the reference signals of multiple cells on the first target measurement frequency point sent by the network device to the terminal device may not be carried in the configuration message of the GAP measurement, that is to say , The network device can directly send the configuration signal of the reference signal to the terminal device. When the length of the measured GAP needs to be determined, the terminal device can determine the length of the measured GAP and determine the measured GAP according to the content carried in the configuration message of the reference signal The length method is the same as the above method, and for the sake of brevity, it will not be repeated here.
