It should be understood that the first target measurement frequency point may be any frequency point different from the frequency point at which the terminal device is currently located, the terminal device performs inter-frequency or inter-system measurement on the first target measurement frequency point, and when the terminal device performs the inter-frequency or inter-system measurement, the terminal device stops sending and receiving data information at the frequency point at which the terminal device is currently located.

Optionally, in some embodiments, the configuration information of the measurement GAP may include length information of the measurement GAP, or may include configuration information of a reference signal of at least one cell on the first target measurement frequency point.

It should be understood that, when the configuration information of the measurement GAP includes length information of the measurement GAP, that is, the network device directly notifies the terminal device of the length of the measurement GAP required for performing inter-frequency or inter-system measurement, the terminal device only needs to perform RRM in the measurement GAP according to the length of the measurement GAP.

When the configuration information of the measurement GAP includes configuration information of a reference signal of at least one cell on the first target measurement frequency point, the configuration information of the reference signal is used for the terminal device to determine the length of the measurement GAP according to the configuration information of the reference signal, that is, the network device sends information required for determining the length of the measurement GAP to the terminal device through the configuration information of the measurement GAP, so that the terminal device determines the length of the measurement GAP according to the information sent by the network device.

Optionally, in some embodiments, the configuration information of the reference signal may be used to indicate time-frequency resource information of the reference signal, and may further include the number of reference signals currently actually transmitted.

Optionally, in some embodiments, the RRM measurement may be a Reference Signal Receiving Power (RSRP) measurement, a Reference Signal Receiving Quality (RSRQ) measurement, or another type of measurement, which is not limited in this embodiment of the present invention.

Optionally, in some embodiments, the reference Signal may be a synchronization Signal Block (SS Block), a Channel state information reference Signal (CSI-RS), or both of them, or another reference Signal.

It should be understood that the embodiments of the present invention only use the two reference signals as examples to describe the reference signals, but the embodiments of the present invention are not limited thereto.

When the Reference Signal is SS Block, the network device sends SS burst set to the terminal device, where the SS burst set includes multiple SS blocks, each SS Block includes a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSs), and a Physical Broadcast Channel (PBCH) Signal, and the terminal device performs RRM measurement based on the SSs in the SS Block and/or a Demodulation Reference Signal (DMRS) in the PBCH.

Optionally, in some embodiments, when the configuration information of the measurement GAP includes configuration information of a reference signal of at least one cell on the first target measurement frequency point, the terminal device may determine, according to the configuration information of the reference signal of the at least one cell, a first transmission duration of the reference signal, and then determine, according to the first transmission duration, a length of the measurement GAP.

It should be understood that the first transmission duration may be a transmission duration satisfying a preset condition among transmission durations of reference signals of multiple cells on the first target frequency point.

Optionally, when the terminal device determines the first transmission time length of the reference signal according to the configuration information of the reference signal of at least one cell, the configuration information of the reference signal corresponding to the transmission time length meeting the preset condition in the transmission time lengths of the reference signals may be selected from the configuration information of the reference signals of multiple cells, the selected configuration information of the reference signal may be determined as the first reference signal configuration information, and then the first transmission time length is determined according to the first reference signal configuration information.

Optionally, when the terminal device determines the first transmission duration of the reference signal according to the configuration information of the reference signal of at least one cell on the first target frequency point, the configuration information of the reference signal sent by the network device and received by the terminal device may be the configuration information of the first reference signal selected by the network device from the configuration information of the reference signals of multiple cells, and the transmission duration of the reference signal corresponding to the configuration information of the first reference signal meets the transmission duration of the preset condition, that is, when the network device sends the configuration information of the reference signal to the terminal device, the configuration information of the reference signal meeting the requirement may be selected first, and after the configuration information of the reference signal meeting the requirement is selected, the configuration information of the reference signal meeting the requirement is sent to the terminal device, so that the terminal device may avoid calculating the transmission duration of the reference signal of each cell according to the configuration information of each reference signal, the efficiency of the terminal equipment for determining the transmission time of the reference signal is improved, and the signaling overhead is reduced.

Optionally, the terminal device may further determine, according to the received configuration information of the reference signals of the multiple cells sent by the network device, the transmission duration of the reference signal of each of the multiple cells, and then determine, as the first transmission duration, a transmission duration that meets a preset condition in the transmission durations of the reference signals.

Optionally, the transmission duration meeting the preset condition in the transmission durations of the reference signal may be a transmission duration having a maximum value, or may also be a transmission duration greater than or equal to a preset threshold, and when there are multiple transmission durations greater than or equal to the preset threshold, one transmission duration may be arbitrarily selected from the multiple transmission durations as the first transmission duration, or one transmission duration may be selected as the first transmission duration according to a predetermined rule, which is not limited in the embodiment of the present invention.

The determination of the length of the measurement GAP based on the configuration information of the reference signal is described below, taking the reference signal as SS Block as an example.

In the prior art, the maximum number of reference signals transmitted is different in different frequency bands, as shown in table 1, the maximum number of reference signals transmitted is 4 in a frequency band less than 3GHz, the maximum number of reference signals transmitted is 8 in a frequency band from 3GHz to 6GHz, and the maximum number of reference signals transmitted is 64 in a frequency band from 6GHz to 56.2GHz, in order to satisfy the transmission of the maximum number of reference signals, the transmission time length for transmitting the reference signals is generally set as the transmission time length required when the number of reference signals is maximum, however, the number of reference signals transmitted in actual reference signal transmission is not always the maximum number, and the number of reference signals transmitted may be smaller than the maximum number of reference signals in most cases, at this time, in the embodiment of the present invention, the terminal device may transmit the configuration information of the reference signals according to the network device, a transmission duration of the reference signal is determined.

TABLE 1 maximum number of reference signals

Frequency band	Maximum number of reference signals
		Less than 3GHz	4
3GHz-6GHz	8
		6GHz-56.2GHz	64

The terminal device may obtain the start time and/or the end time of the transmission of the reference signal of each of the multiple cells on the first target measurement frequency point from the configuration information of the reference signals of the multiple cells on the first target measurement frequency point sent by the network device, or may also obtain the number of the reference signals actually transmitted in each cell, and according to these information, the terminal device may determine the transmission duration of the reference signal of each of the multiple cells on the first target measurement frequency point, or select the configuration information of the reference signal with the longest transmission duration of the reference signal from the configuration information of the reference signals of the multiple cells, and then determine the first transmission duration according to the transmission duration satisfying the preset condition in the transmission durations of the reference signals of each cell or the configuration information of the reference signal corresponding to the transmission duration satisfying the preset condition, and then determining the length of the measurement GAP according to the first transmission time length.

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 time length of the reference signal selected by the network device, where the transmission time length of the reference signal meets the preset condition, and the terminal device determines the first transmission time length according to the start time and the end time of transmission of the reference signal included in the configuration information of the reference signal or the number of actually transmitted reference signals, and then determines the length of the measurement GAP according to the first transmission time length.

Optionally, the number of the reference signals actually transmitted in the cell obtained by the terminal device may be notified to the terminal device by the network device in a manner of indication information, the indication information may also carry a selection rule of the position of the actually transmitted reference signal in the time domain, the selection rule may be a preset rule, and the indication information may be a field in configuration information of the reference signal.

For example, when the frequency band for performing inter-frequency measurement is a frequency band of 3GHz or less, the reference signal is SS Block, and the transmission is performed at a subcarrier interval of 15KHz, in this case, the maximum number of transmissions of the reference signal is 4, and the transmission duration is 2ms, however, the number of the actually transmitted reference signals is 2, and the actually transmitted reference signals are the reference signals transmitted at the first time domain position and the second time domain position on the time domain position where the 4 reference signals are originally transmitted, the network device may send the indication information to the terminal device, the indication information includes that the number of reference signals actually transmitted is 2, the selection rule of the reference signals is to select the reference signals transmitted at the first time domain position and the second time domain position of the time domain positions where 4 reference signals are originally transmitted, at this time, the terminal equipment can determine the transmission time length of the transmitted reference signal to be 1ms according to the indication information.

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

For example, when the frequency band for performing inter-frequency measurement is a frequency band below 3GHz, the reference signal is SS Block, and a subcarrier interval of 15KHz is used for transmission, in this case, the maximum transmission number of the reference signal is 4, and the transmission duration is 2ms, however, at this time, the number of the reference signals actually transmitted is 2, the network device may send a field of "1100" to the terminal device, and indicate the terminal device to transmit the reference signal at the first time domain position and the second time domain position on the time domain position where the 4 reference signals were originally transmitted, and through this field, the terminal device may know that the reference signals actually transmitted occupy the first two time domain positions of the time domain positions where the 4 reference signals were originally transmitted, and therefore, the terminal device may determine that the transmission duration for transmitting the reference signals is 1 ms; when a field sent to the terminal device by the network device is "0101", the field indicates that the terminal device transmits the reference signal at the second time domain position and the fourth time domain position on the time domain position where the 4 reference signals were originally transmitted, and if the transmission start time of the reference signal carried in the configuration information of the reference signal is the first time domain position of the time domain position where the 4 reference signals were originally transmitted, the terminal device can determine that the transmission duration of the reference signal is still 2ms at this time.

Therefore, the terminal device may determine the transmission duration of the reference signal in the cell according to the number of actually transmitted reference signals, the information such as 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 measurement GAP may be the first transmission duration, or may be greater than the first transmission duration.

Optionally, in some embodiments, because synchronization between cells at the first target measurement frequency may not be very accurate, there is a certain error in transmission duration when each cell transmits a reference signal, and in order to compensate for the influence of the error on the length of the measurement GAP, a time margin may be added to the first transmission duration to obtain the measurement GAP after the first transmission duration is determined, so as to ensure that the determined measurement GAP may cover the transmission durations of the reference signals transmitted by all cells at the first target measurement frequency.

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, the length of the measurement GAP may be obtained by adding the preset time margin to the first transmission duration.

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

The time synchronization relationship may include at least symbol-level synchronization and slot-level synchronization, where the symbol-level synchronization is that transmission durations for transmitting reference signals between every two cells in the plurality of cells differ by a duration of one symbol, and the slot-level synchronization is that transmission durations for transmitting reference signals between every two cells in the plurality of cells differ by a duration of one slot.

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

Optionally, in some embodiments, the terminal device receives synchronization status indication information sent by the network device, where the synchronization status indication information 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 further indicate the time synchronization relationship between the cells to the terminal device in the form of a bit, for example, the network device may indicate the time synchronization relationship between the cells to the terminal device in the form of a 1-bit field or a 2-bit field, the network device may use "0" to indicate that the time synchronization relationship between the cells is symbol-level synchronization, "1" to indicate that the synchronization relationship between the cells is slot-level synchronization, or may also use "00" to indicate that the time synchronization relationship between the cells is symbol-level synchronization, "01" to indicate that the synchronization relationship between the cells is slot-level synchronization, "10" to indicate that the cells are not synchronized, and so on.

Optionally, in some embodiments, when there is no synchronization between multiple cells on the first target measurement frequency point, the measurement GAP may be set to be a default 6 ms.

Therefore, when determining the length of the measurement GAP, it may first determine whether multiple cells on the first target measurement frequency are synchronized, and when multiple cells are synchronized or approximately synchronized, the length of the measurement GAP may be determined according to the configuration information of the reference signal and the time margin, and when multiple cells are not synchronized, the length of the measurement GAP may be directly set to 6 ms.

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

When the reference signal includes both SS Block and CSI-RS, when determining the length of the measurement GAP, it needs to determine whether there is a time interval between SS Block transmission and CSI-RS transmission, and if there is a time interval, the length of the measurement GAP should be the sum of the transmission duration, the time margin, and the time interval between the two reference signals.

For example, in a cell a on a first measurement target frequency point, according to the configuration information of the reference signal, it is determined that the transmission duration for transmitting the reference signal SS Block is T1, the transmission duration for transmitting the reference signal CSI-RS is T2, the transmission interval between the reference signal SS Block and the reference signal CSI-RS is T0, and the time margin is T3, and assuming that the first measurement target frequency point only includes the cell a, it may be determined that the measurement GAP is T1+ T2+ T3+ T0, i.e. measuring the length of the GAP needs to cover the reference signal SS Block and the reference signal CSI-RS, when the first measurement target frequency point further includes other cells, the transmission durations of the two reference signals of each cell may be respectively calculated, and then the first transmission durations of the two reference signals are respectively calculated, and the sum of the first transmission durations of the two reference signals and the transmission interval and the time margin between the reference signals is determined as the length of the measurement GAP.

In the above embodiment, how to determine the length of the measurement GAP is described by taking an example that the terminal device determines the length of the measurement 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, and if the terminal device directly receives the length information of the measurement GAP, how to determine the length of the measurement GAP is executed by the network device.

The network device may determine the transmission duration of the reference signal of each cell according to the transmission condition of the reference signal of each cell on the first target frequency point, determine a first transmission duration, where the first transmission duration is a transmission duration satisfying a preset condition, determine the length of the measurement GAP according to the first transmission duration, and send the length of the measurement GAP to the terminal device.

Optionally, in some embodiments, the configuration information of the reference signals of the multiple cells on the first target measurement frequency point, which is sent by the network device to the terminal device, may also not be carried in the configuration information for measuring the GAP, that is, the network device may directly send the configuration information of the reference signals to the terminal device, when the length of the measurement GAP needs to be determined, the terminal device may determine the length of the measurement GAP according to the content carried in the configuration information of the reference signals, and the method for determining the length of the measurement GAP is the same as the above method, and is not described herein again for brevity.
