6GHz-56.2GHz6GHz-56.2GHz	6464

The terminal device may obtain, from the configuration information of the reference signals of the multiple cells on the first target measurement frequency point sent by the network device, the start of the reference signal transmission of each of the multiple cells on the first target measurement frequency point. Time and/or end time, or the number of reference signals actually transmitted in each cell, according to which the terminal device can determine a reference signal of each of the plurality of cells on the first target measurement frequency point The transmission duration, or the configuration information of the reference signal having the longest transmission duration of the reference signal is selected from the configuration information of the reference signals of the plurality of cells, and then the transmission duration that satisfies the preset condition according to the transmission duration of the reference signal of each cell Or determining the configuration information of the reference signal corresponding to the transmission duration that meets the preset condition, determining the first transmission duration, and then determining the length of the measurement GAP according to the first transmission duration.

It should be understood that the configuration information of the reference signal received by the terminal device may also be the configuration information of the reference signal corresponding to the transmission duration of the reference signal selected by the network device that meets the preset condition, and the terminal device includes the reference according to the reference signal configuration information. The start time, the end time of the transmission of the signal, or the number of reference signals actually transmitted, determine the first transmission duration, and determine the length of the measurement GAP according to the first transmission duration.

Optionally, the number of the reference signals that are actually transmitted by the terminal device in the cell may be notified by the network device by using the indication information, where the indication information may also carry the location of the actual transmitted reference signal in the time domain. The rule may be a preset rule, and the indication information may be a field in the configuration information of the reference signal.

For example, when the frequency band in which the inter-frequency measurement is performed is in the frequency band below 3 GHz, the reference signal is SS Block, and when the subcarrier spacing is transmitted at 15 kHz, in this case, the maximum number of transmissions of the reference signal is 4, and the transmission duration is 2 ms. However, the number of reference signals actually transmitted is two, and the actually transmitted reference signal is transmitted in the first time domain position and the second time domain position in the time domain position of the original transmission of four reference signals. Reference signal, the network device can send to the terminal device Sending indication information, where the number of reference signals actually transmitted is 2, and the selection rule of the reference signal is to select the first time domain position and the second time domain position in the time domain position of the original four transmission reference signals. The reference signal transmitted, at this time, the terminal device can determine, according to the indication information, that the transmission duration of the transmitted reference signal is 1 ms.

Optionally, the number of reference signals that the terminal device obtains the actual transmission in the cell may also be indicated by the network device in the form of a bit to the terminal device.

For example, when the frequency band in which the inter-frequency measurement is performed is in the frequency band below 3 GHz, the reference signal is SS Block, and when the subcarrier spacing is transmitted at 15 kHz, in this case, the maximum number of transmissions of the reference signal is 4, and the transmission duration is 2 ms. However, the number of reference signals actually transmitted at this time is two, and the network device may send a field of "1100" to the terminal device, indicating the first time domain of the terminal device in the time domain position of the original transmission of four reference signals. The location and the second time domain location transmit a reference signal, and the terminal device can learn that the actually transmitted reference signal occupies the first two time domain positions of the time domain location of the original four reference signals, and therefore, the terminal device can determine The transmission reference signal has a transmission duration of 1 ms; when the field transmitted by the network device to the terminal device is “0101”, the field indicates the second time domain location and the fourth location of the terminal device in the time domain position of the original transmission of four reference signals. The reference signal is transmitted in the time domain position. If the reference signal carried in the configuration information of the reference signal is transmitted, the original transmission time is 4 references. First time domain position of the position number of the time domain, at this time, the terminal device may determine the reference length still 2ms transmission signal.

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

It should be understood that the length of the measurement 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 very accurately synchronized, there is a certain error in the transmission duration when each cell transmits the reference signal, in order to compensate the The effect of the error on measuring the length of the GAP may be performed by adding a time margin to the first transmission duration to obtain a measurement GAP after determining the first transmission duration, thereby ensuring that the determined measurement GAP can cover the first target measurement frequency. The transmission duration of the reference signal transmitted by all cells on the point.

Optionally, the time margin may be preset, and after the terminal device determines the first transmission duration according to the configuration information of the reference signal, adding a preset time to the first transmission duration The balance can be obtained by measuring the length of the GAP.

Optionally, the time margin may also determine a time margin according to a 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, where the transmission duration of the transmission reference signal between each of the plurality of cells differs by one symbol, and the slot level synchronization is multiple. The transmission duration of the reference signals transmitted between every two cells in the cell differs by the length of one slot.

Optionally, when the time synchronization relationship between the cells is symbol level synchronization, the determined time margin is smaller than a time synchronization relationship determined when the time synchronization relationship between the cells is a 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. 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 the synchronization status indication information sent by the network device, where the synchronization status indication information is used to indicate a time synchronization relationship between the multiple cells on the first target frequency point.

Optionally, in some embodiments, the network device may further indicate a time synchronization relationship between the cells in the form of a bit, for example, the network device may be in the form of a 1-bit field or a 2-bit field. The device indicates the time synchronization relationship between the cells, and the network device may use "0" to indicate that the time synchronization relationship between the cells is symbol level synchronization, and "1" indicates that the synchronization relationship between the cells is slot level synchronization, or may also be used. "00" indicates 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 cells are not synchronized, and the like.

Optionally, in some embodiments, when the 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 measured GAP, it may first determine whether synchronization is performed between multiple cells on the first target measurement frequency point, and when synchronization or approximate synchronization between multiple cells, according to configuration information of the reference signal and The time margin is determined to measure the length of the GAP. When the multiple cells are not synchronized, the length of the measurement GAP can be directly set to 6 ms.

When the determined measurement GAP length is less than 6 ms, the terminal device can transmit or receive data information at a time other than the determined measurement GAP length, thereby reducing the influence of the measurement GAP on the data transmission.

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

For example, in the cell A at the first measurement target frequency, 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, and the reference signal SS Block The transmission interval between the reference signal CSI-RS and the reference signal CSI-RS is T0, and the time margin is T3. If the first measurement target frequency point only includes the cell A, it can be determined that the measurement GAP is T1+T2+T3+T0, that is, measurement The length of the GAP needs to cover the reference signal SS Block and the reference signal CSI-RS. When the other measurement target frequency points include other cells, the transmission durations of the two reference signals of each cell may be separately calculated, and then the foregoing calculations are respectively performed. The first transmission duration of the two reference signals determines the sum of the first transmission duration of the two reference signals and the transmission interval and the time margin between the reference signals as the length of the measurement GAP.

In the above embodiment, the terminal device determines the length of the measured GAP according to the configuration information of the reference signal of the reference signal of the at least one cell of the first target measurement frequency point sent by the network device, and describes how to determine the length of the measured GAP, if the terminal device directly Receiving the length information of the measurement GAP, how to determine the length of the measurement GAP will be performed by the network device.

And determining, according to the first transmission duration, the length of the measured GAP, and transmitting the length of the measurement GAP to the terminal device.

When the length of the measurement GAP needs to be determined, the terminal device can determine the length of the measured GAP according to the content carried in the configuration information of the reference signal, and determine the length of the measured GAP. The method is the same as the above method, and is not described here for brevity.
