Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of communication, in particular to a scheduling method of measurement gap and device thereof. BACKGROUND

[0002] In a new radio (NR) system, when a terminal device performs mobility measurement, if the reference signal of the to-be-measured neighbor cell is not in the current activated bandwidth part (BWP) frequency domain, the terminal device needs to measure a gap to complete the mobility measurement.

[0003] Generally, the BWP can be switched by a downlink control information (DCI), a timer, and the like. When the BWP is switched by the DCI indication, the switching is more dynamic or faster than the measurement gap. In this case, the network can always assume that the measurement gap is used for mobility measurement, which will cause a loss of throughput for the network and the terminal.

[0069] To facilitate understanding, first introduce the terms involved in the present application.

[0070] 1. Downlink control information (DCI)

[0071] DCI is carried by a physical downlink control channel (PDCCH), and DCI can include uplink and downlink resource allocation, hybrid automatic repeat request (HARQ) information, power control, etc. The PDCCH is a physical channel used to carry downlink scheduling information.

[0072] 2. Bandwidth part (BWP)

[0073] BWP (Bandwidth Part) is a subset of the total bandwidth, which flexibly adjusts the terminal device receiving and transmitting bandwidth size through bandwidth adaptation in NR, so that the terminal device receiving and transmitting bandwidth does not need to be as large as the bandwidth of the cell.

[0074] 3. Measurement gap

[0075] The measurement gap is a kind of inter-frequency measurement mode, and the specific operation is as follows: when inter-frequency measurement is performed, a part of time (i.e., measurement gap time) is reserved, in which time, the terminal device does not send and receive any data, and the receiver is adjusted to the target cell frequency point to perform inter-frequency measurement, and then is switched to the current cell after the interval time ends.

[0076] In order to better understand the scheduling method of the measurement gap disclosed in the embodiments of the present application, first, the communication system to which the embodiments of the present application are applicable is described below.

[0077] Please refer to Figure 1 , Figure 1 The architecture of a communication system provided by the embodiments of the present application is shown in the figure. The communication system can include, but is not limited to, one network device and one terminal device, Figure 1 The number and form of devices shown in the figure are only for example and do not constitute a limitation on the embodiments of the present application, and in actual applications, two or more network devices and two or more terminal devices can be included.

[0081] It can be understood that the communication system described in the embodiments of the present application is for more clearly illustrating the technical solutions of the embodiments of the present application, and does not constitute a limitation on the technical solutions provided by the embodiments of the present application. Those skilled in the art can know that the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems as the system architecture evolves and new service scenarios appear.

[0082] The method for scheduling measurement gap and the device thereof provided by the present application will be described in detail below with reference to the accompanying drawings.

[0083] Please refer to Figure 2 , Figure 2 is a method flow diagram for scheduling measurement gap provided by the embodiments of the present application, which is executed by a terminal device. As Figure 2 shown, the method can include but is not limited to the following steps:

[0084] Step S21: receiving first indication information, wherein the first indication information is used to indicate the state of the measurement gap.

[0085] In the present disclosure, considering that when the BWP is switched by the DCI command, the BWP switching is faster than the measurement gap, in order to avoid the network always assuming that the measurement gap is used for mobility measurement, causing the waste of resources, the network device can indicate the state of each measurement gap to the terminal device through the first indication information, and then the terminal device can quickly activate or deactivate the measurement gap according to the measurement gap state indicated in the indication information, thereby avoiding resource waste.

[0086] In the present disclosure, when the terminal device receives the BWP switching instruction, it can determine the state of the measurement gap on the currently activated BWP according to the first indication information, and then dynamically activate or deactivate the measurement gap.

[0087] Optionally, the first indication information can include the state of the measurement gap corresponding to each configured BWP on each serving cell, or can include the state of the measurement gap corresponding to each serving cell. The state of the measurement gap can include activation or deactivation.

[0088] By implementing the embodiments of the present disclosure, the terminal device can dynamically activate or deactivate the measurement gap according to the state of the measurement gap in the first indication information after receiving the indication information. In this way, it can be avoided that the measurement gap is always assumed to be used for mobility measurement, thereby facilitating to avoid resource waste.

[0089] Please refer to Figure 3 , Figure 3 is another method flow diagram for scheduling measurement gap provided by the embodiments of the present application. AsFigure 3 As shown, the method can be performed by a terminal device, and can include but is not limited to the following steps:

[0090] Step S31: receiving first indication information, the first indication information being used to indicate the state of measurement gap on each configured BWP of each serving cell.

[0091] In the present disclosure, there can be multiple serving cells for each terminal device, each cell can be configured with multiple BWPs, and the terminal device can perform mobility measurement on each cell. Therefore, the first indication information can contain the state indication information of measurement gap of each BWP configured by each serving cell, so that the terminal device can quickly query the state of measurement gap on the currently activated BWP based on the first indication information when performing BWP switching.

[0092] Optionally, the first indication information can be organized in the following manner. When implemented, the content indicated in the first indication information can be as shown in Table 1 below:

[0093] Table 1

[0094]

[0095] In the above table, ON represents that the configured measurement gap is in the activated state, OFF represents that the configured measurement gap is in the deactivated state, the column of ServCellIndex represents the serving cell number, and the next row of BWP-Id represents the BWP number. The intersection cell of ServCellIndex#0 row and BWP-Id#0 column is ON, indicating that when the terminal device is in the serving cell with index 0 and switches to the BWP with number 0, the measurement gap should be set to the activated state. Similarly, the intersection cell of ServCellIndex#0 row and BWP-Id#1 column is OFF, indicating that when the terminal device is in the serving cell with index 0 and switches to the BWP with number 1, the measurement gap should be set to the deactivated state.

[0096] It can be understood that each element and each corresponding relationship in Table 1 exists independently; these elements and corresponding relationships are exemplarily listed in the same table, but it does not mean that all elements and corresponding relationships in the table must exist at the same time according to Table 1. The value of each element and each corresponding relationship is independent of any other element value or corresponding relationship in Table 1. Therefore, those skilled in the art can understand that the value of each element and each corresponding relationship in Table 1 is an independent embodiment.

[0097] Optionally, the above first indication information can also refer to the current protocol form to indicate the number of serving cells and the state of measurement gap on each serving cell.

[0098] For example, the first indication information indicates that the terminal device currently corresponds to 4 serving cells, the measurement gap state of the serving cell 1 is active, the measurement gap state of the serving cell 2 is deactivated, the measurement gap state of the serving cell 3 is deactivated, and the measurement gap state of the serving cell 4 is active. When the terminal device performs mobility measurement, if the current serving cell is the serving cell 3, it can be known from the first indication information that the current measurement gap is deactivated, so that the measurement gap can be deactivated.

[0099] It can be understood that the indication form and the state transformation of the measurement gap are not dependent on the switching of the BWP, but are dependent on the switching of the serving cell.

[0100] By implementing the embodiments of the present disclosure, the first indication information can more comprehensively and effectively indicate the state of the measurement gap corresponding to each BWP, so that the terminal device can dynamically adjust the state of the measurement gap according to the switching of the BWP, thereby avoiding the network being always in the state of the activated measurement gap and wasting resources.

[0101] Please refer to Figure 4 , Figure 4 is another method flow diagram for scheduling the measurement gap provided by the embodiments of the present disclosure, and the method is executed by the terminal device. As shown in Figure 4 , the method can include but is not limited to the following steps:

[0102] Step S41: receiving first indication information based on the measurement gap configuration signaling, the first indication information being used to indicate the state of the measurement gap.

[0103] In the communication system, information is usually transmitted in a certain way. In the present disclosure, the first indication information can be recorded in the measurement gap configuration command MeasGapConfig, that is, the network device can indicate the state of each measurement gap when configuring the measurement gap for the terminal device.

[0104] The content and implementation form of the first indication information can refer to any embodiment of the present disclosure, which will not be described here

[0105] Step S42: activating or deactivating the measurement gap according to the state of the measurement gap in the first indication information.

[0106] In the present disclosure, after the terminal device receives the first indication information, it can query the state of the corresponding measurement gap according to the to-be-measured cell and the currently activated BWP. When the state of the measurement gap is activated, the measurement gap is activated. When the state of the measurement gap is deactivated, the measurement gap is deactivated.

[0107] For example: Suppose that the terminal device is currently in the Serving Cell of ServCellIndex#1 and the activated BWP is BWP-id#1. By querying the first indication information, it can be determined that the measurement gap corresponding to ServCellIndex#1 and BWP-id#1 is in an active state, and then the measurement gap can be activated.

[0108] Optionally, when the terminal device switches to BWP-id#2 according to the BWP handover instruction information, the terminal device can query the status indication information of the measurement gap corresponding to BWP-id#2 of the serving cell ServCellIndex#1 in the first instruction information. When the status indication information is active, the measurement gap is kept active and mobility measurement is performed; when the status indication information is deactivated, the measurement gap is deactivated and mobility measurement is not performed.

[0109] By implementing the embodiments of this disclosure, the terminal device can quickly update the status of the measurement gap as needed, based on the status of the measurement gap indicated in the measurement gap configuration signaling. This avoids the measurement gap from remaining in an active state, saving resources.

[0110] Please see Figure 5 , Figure 5 This is a schematic flowchart of another method for scheduling measurement gaps provided in this application embodiment, which is executed by a terminal device. Figure 5 As shown, the method may include, but is not limited to, the following steps:

[0111] Step S51: Receive second indication information, wherein the second indication information is used to indicate the BWP after the switch.

[0112] Optionally, the second indication information can be DCI information.

[0113] In this disclosure, when the terminal device is moving, the network device can send BWP handover instruction information to the terminal device in real time according to the current location of the terminal device, so as to instruct the terminal device to perform BWP handover.

[0114] Step S52: Activate or deactivate the measurement gap corresponding to the switched BWP according to the status of the measurement gap corresponding to the switched BWP in the first instruction information.

[0115] Wherein, each BWP in each serving cell can correspond to a measurement gap state, when the terminal device receives the BWP switching indication, the terminal device can determine the interval gap state corresponding to the switched BWP according to the BWP state indicated in the first indication information, and then switch the measurement gap state, so that the switching of the measurement gap can be synchronized with the switching of the BWP. Wherein, the first indication information can be pre-configured in the terminal device, or the terminal device can receive the first indication information before receiving the second indication information, or the terminal device can receive the first indication information at the same time as receiving the second indication information. In this disclosure, after receiving the first indication information and the second indication information, the terminal device can query the state of the measurement gap indicated by the first indication information according to the serving cell and the second indication information for indicating the BWP switching, to determine the state of the measurement gap corresponding to the switched BWP. When the state of the measurement gap is activated, the measurement gap is activated; when the state of the measurement gap is deactivated, the measurement gap is deactivated.

[0116] For example, assuming that the terminal device is currently located in the ServCellIndex#1 serving cell, the activated BWP is BWP-id#1, and the measurement gap is activated, and the terminal device receives the second indication information indicating the switched cell as BWP-id#2. The terminal device can determine the state of the measurement gap corresponding to the ServCellIndex#1 serving cell and the BWP-id#2 according to the indication in the first indication information. When the state indication information is activated, the measurement gap is kept in the activated state and the mobility measurement is performed; when the state indication information is deactivated, the measurement gap is deactivated and the mobility measurement is not performed. Through the implementation of the embodiments of the disclosure, after receiving the second indication information for indicating the BWP switching, the terminal device can activate or deactivate the measurement gap according to the state of the measurement gap corresponding to the switched BWP in the first indication information. In this way, the measurement gap can be avoided to be always in the state of being assumed for mobility measurement, thereby facilitating to avoid resource waste. Please refer to Figure 6 , Figure 6 is another method flow diagram for scheduling the measurement gap provided by the embodiments of the present application, which is executed by the network device. As shown in Figure 6 , the method can include but is not limited to the following steps:

[0117] Step S61: sending first indication information, wherein the first indication information is used to indicate the state of the measurement gap.

[0118] In the present disclosure, considering that the BWP switching is faster than the measurement gap when the BWP is switched by means of the DCI command, in order to avoid the network always assuming the measurement gap for mobility measurement, causing the waste of resources, the network device can indicate the state of each measurement gap to the terminal device through the first indication information, so that the terminal device can quickly activate or deactivate the measurement gap according to the measurement gap state indicated in the first indication information, thereby avoiding resource waste.

[0119] Optionally, the first indication information can include the state of the measurement gap corresponding to each configured BWP on each serving cell, or can include the state of the measurement gap corresponding to each serving cell. The state of the measurement gap can include activation or deactivation.

[0120] By implementing the embodiments of the present disclosure, the network device indicates the state of the measurement gap to the terminal device, so that the terminal device can dynamically activate or deactivate the measurement gap. In this way, it can be avoided that the measurement gap is always assumed to be used for mobility measurement, thereby facilitating to avoid resource waste.

[0121] Please refer to Figure 7 , Figure 7 is another method flow diagram for scheduling the measurement gap provided by the embodiments of the present application, and the method is performed by the network device. As Figure 7 shown, the method can include but is not limited to the following steps:

[0122] Step S71: sending first indication information, the first indication information being used to indicate the state of the measurement gap on each configured BWP on each serving cell.

[0123] In the present disclosure, there can be multiple serving cells for each terminal device, each cell can be configured with multiple BWP, and the terminal device can perform mobility measurement on each cell. Therefore, the first indication information can include the state indication information of the measurement gap of each BWP configured by each serving cell, so that the terminal device can quickly query the state of the measurement gap on the currently activated BWP based on the first indication information when performing BWP switching.

[0124] Optionally, the content indicated in the first indication information can be as shown in Table 1 in the present disclosure, which will not be described here again.

[0125] It can be understood that the network device sends the first indication information to the terminal device, and the terminal device can quickly query the state of the corresponding measurement gap when performing BWP switching after receiving the first indication information, and then activate or deactivate the measurement gap.

[0126] Optionally, the first indication information can also indicate the number of serving cells and the state of the measurement gap on each serving cell according to the current protocol form.

[0127] For example, the first indication information indicates that the terminal device currently corresponds to 4 serving cells, the measurement gap state of the serving cell 1 is active, the measurement gap state of the serving cell 2 is deactivated, the measurement gap state of the serving cell 3 is deactivated, and the measurement gap state of the serving cell 4 is active. When the terminal device performs mobility measurement and the current serving cell is the serving cell 3, it can be known from the first indication information that the current measurement gap is deactivated, so the measurement gap can be deactivated.

[0128] It can be understood that the indication form and the state transformation of the measurement gap are not dependent on the switching of the BWP, but are dependent on the switching of the serving cell.

[0129] Through the implementation of the embodiments of the present disclosure, the indication information can more comprehensively and effectively indicate the state of the measurement gap corresponding to each BWP, so that the terminal device can dynamically adjust the state of the measurement gap according to the switching of the BWP, thereby avoiding the network being in the state of the measurement gap being activated all the time and wasting resources.

[0130] Please refer to Figure 8 , Figure 8 is another method flow diagram for scheduling the measurement gap provided by the embodiments of the present application, and the method is executed by the network device. As shown in Figure 8 , the method can include but is not limited to the following steps:

[0131] Step S81: sending first indication information based on measurement gap configuration signaling.

[0132] In a communication system, information is usually transmitted in a certain way. In the present disclosure, the indication information can be recorded in the measurement gap configuration command MeasGapConfig, that is, the network device can indicate the state of each measurement gap when configuring the measurement gap for the terminal device.

[0133] In the present disclosure, after the terminal device receives the first indication information, it can query the state of the corresponding measurement gap according to the serving cell and the currently activated BWP. When the state of the measurement gap is active, the measurement gap is activated; when the state of the measurement gap is deactivated, the measurement gap is deactivated.

[0134] For example, assuming that the terminal device currently locates in a serving cell ServCellIndex#1 and the activated BWP is BWP-id#1, and the measurement gap is activated. When the terminal device switches to BWP-id#2 according to the BWP switching indication information, the terminal device can query the state indication information of the measurement gap corresponding to BWP-id#2 of the ServCellIndex#1 serving cell in the first indication information. When the state indication information is activated, the measurement gap is kept in the activated state, and the mobility measurement is performed. When the state indication information is deactivated, the measurement gap is deactivated, and the mobility measurement is not performed.

[0135] By implementing the embodiments of the present disclosure, the network device indicates the state of the measurement gap to the terminal device through the measurement gap configuration signaling, and then the terminal device can quickly update the state of the measurement gap according to the needs. In this way, the measurement gap is avoided to be always activated, and the resources are saved.

[0136] Please refer to Figure 9 , Figure 9 is another method flow diagram for scheduling the measurement gap provided by the embodiments of the present application, and the method is executed by the network device. As Figure 9 shown, the method can include but is not limited to the following steps:

[0137] Step S91: sending second indication information, wherein the second indication information is used to indicate the switched BWP.

[0138] Optionally, the second indication information can be DCI information.

[0139] In the present disclosure, the network device can send the BWP switching indication information to the terminal device in real time according to the current location of the terminal device during the movement of the terminal device, so as to instruct the terminal device to switch the BWP.
