Description

Gap selection method and device

Technical field

The present invention relates to the field of communications, and in particular, to a Gap selection method and apparatus.

Background technique

In a wireless communication system, a user equipment (English: user equipment; abbreviated as: UE) needs to measure a signal of a neighboring cell adjacent to a serving cell while communicating with a base station controlling a serving cell in a serving cell (Cell). In order to perform cell handover at an appropriate timing, the neighboring cell is also switched to the serving cell of the UE. Due to the limitation of the transceiver, the UE cannot communicate with the base station and perform neighbor cell measurement at the same time. In this case, the base station needs to configure the measurement Gap for the UE, and the measurement Gap is the period during which the UE performs measurement. The UE interrupts communication with the base station in the measurement Gap to perform neighbor cell measurement; during the time other than measuring Gap, the UE maintains communication with the base station. Specifically, the base station configures a measurement Gap mode for the UE, and the measurement Gap mode specifies the time when the measurement Gap appears. For example, in one measurement Gap mode, one measurement gap occurs every 40 ms.

Device to Device (D2D) refers to a mode in which UEs discover and communicate with each other through a side link (English: Sidelink; SL: short). In this mode, a UE directly Information is transmitted to another UE without relaying through the base station. The D2D resources used by the UE on the SL are part of the serving cell or neighbor cell resources. Due to the limitations of the transceiver, the UE cannot transmit data packets on the SL and maintain communication with the base station at the same time. In this case, the base station needs to configure the SL Gap for the UE, and the SL Gap is the period during which the UE performs side-link transmission or reception (period) ). The UE interrupts communication with the base station in the SL Gap, and transmits the data packet on the SL; the UE maintains communication with the base station outside the time of the SL Gap.

The base station may configure the measurement Gap and the SL Gap for the same UE as needed. When the UE cannot transmit the data packet in the SL while performing the neighbor cell measurement, the base station needs to configure the UE with the SL Gap and the measurement that are completely staggered from each other. Gap, so that the SL Gap and the measurement Gap do not conflict with each other, so that the UE can transmit the data packet on the SL in the SL Gap without the neighboring area measurement; the neighboring area measurement is performed in the measurement Gap, and the data packet is not transmitted on the SL. Maintain communication with the base station outside of the measurement gap and outside of the SL Gap. The above configuration requirements cause the base station to configure the measurement Gap and SL Gap for the UE. Often complicated, affecting the efficiency of the Gap configuration.

Referring to FIG. 3A, a flowchart of still another method for selecting a Gap according to an embodiment of the present invention is shown. In this embodiment, the UE selects a measurement Gap or SL Gap according to a relative priority between the measurement Gap and the SL Gap. . The Gap selection method may include:

In step 301, the base station determines a measurement Gap configured for the UE.

When the method is applied to a long term evolution (LTE) system, the base station is specifically an eNB (eNodeB); when the method is applied to a universal mobile telecommunications system (English: (universal mobile telecommunications system; UMTS for short) The base station is specifically an NB (NodeB); when the method is applied to wireless fidelity (English: Wireless Fidelity; English: WiFi), the base station is specifically an access point (English: access point; abbreviation: AP).

Generally, one UE includes one transceiver, and one transceiver can only transmit and receive signals at one frequency point at the same time. Therefore, when the neighboring cell of the serving cell of the UE is different from the serving cell, the base station needs to configure the measurement Gap for the UE. In order to enable the UE to interrupt communication with the base station in the measurement Gap, the neighboring area measurement is performed; in the time other than the measurement of the Gap, the UE maintains communication with the base station, and does not perform neighboring area measurement.

In this embodiment, the base station configures the time when the measurement Gap occurs for the UE according to various factors, wherein the time for measuring the Gap occurrence is determined by the start time, the period of occurrence of the measurement Gap, and the duration of the measurement Gap. The start time may be directly sent by the base station, or may be calculated by the UE according to the offset after the base station sends the offset, which is not limited in this embodiment.

In this embodiment, the base station configures the occurrence period of the measurement Gap according to the number of different frequencies measured by the base station as an example for description. Specifically, when the number of different frequencies is large, the occurrence period of the measurement Gap is configured to be small; when the number of different frequencies is small, the appearance period of the measurement Gap is configured to be large.

When configuring the duration of each measurement Gap, in one possible implementation, the duration that each measurement Gap is configured by the base station when configuring the measurement Gap; in another possible implementation, by the UE Determine how long each measurement Gap lasts.

Wherein, when the UE determines the duration of each measurement Gap, the UE can read the duration of each measurement Gap specified in the communication protocol; or the UE can determine the duration of each measurement Gap itself. When the UE determines the duration of each measurement Gap, the UE may notify the base station of the duration of each measurement Gap, or may not notify the base station, which is not limited in this embodiment.

Step 302: The base station generates configuration information, where the configuration information is used to indicate a time when the measurement Gap appears.

Step 303: The base station sends configuration information to the UE.

Step 304: The UE receives configuration information sent by the base station.

Step 305: The UE determines, according to the time when the Gap is measured and the time when the SL Gap appears, whether the measurement Gap and the SL Gap conflict, and the time when the SL Gap appears is configured according to a predetermined policy.

Among them, the time of occurrence of SL Gap is determined by the starting time, the appearance period of SL Gap and the duration of SL Gap.

In this embodiment, the configuration of the time when the SL Gap occurs may be sent by the base station, or may be determined by the UE. The following two implementation manners are respectively introduced:

When the configuration of the appearance period of the SL Gap is sent by the base station, the base station configures the appearance period of the SL Gap for the UE according to various factors. For example, the base station configures the appearance period of the SL Gap for the UE according to the available resources, thereby ensuring that the available resources are available for the UE. Transfer packets in SL Gap. The UE transmitting the data packet in the SL Gap may specifically include: the UE receives the data packet on the SL through the SL Gap, or the UE sends the data packet on the SL through the SL Gap.

It should be noted that, when configuring the appearance period of the SL Gap, in a possible manner, the base station configures an appearance period for each SL Gap. For example, the appearance period of each SL Gap is 40 ms, and every 40 ms occurs. An SL Gap; In another possible implementation, the base station configures a SL Gap packet as a packet by using a predetermined number of SL Gaps, for example, three SL Gaps as one packet, and each SL Gap The occurrence period of the packet is 40 ms, and a SL Gap packet appears every 40 ms.

When the duration of the SL Gap is configured, in a possible implementation manner, the duration of the SL Gap is configured by the base station when configuring the appearance period of the SL Gap; in another possible implementation, the UE determines The duration of SL Gap. Wherein, when the UE determines the duration of the SL Gap, the UE can read the duration of the SL Gap specified in the communication protocol; or the UE can determine the duration of the SL Gap itself. When the UE determines the duration of the SL Gap, the UE may notify the base station of the duration of the SL Gap, or may not notify the base station, which is not limited in this embodiment.

It should be noted that, in configuring the duration of the SL Gap, in one possible manner, the base station configures the duration of each SL Gap, for example, the duration of each SL Gap is 10 ms; in another possibility In the implementation manner, the base station configures a predetermined number of SL Gaps as one packet, and configures a duration of the SL Gap packet, for example, three SL Gaps are used as one packet, and each SL Gap packet lasts for 100 ms. At this time, configure 3 durations of 10ms in a period of 100ms. SL Gap. For example, SL Gap occurs when the 10ms, 30ms, and 50ms are configured, or SL Gap occurs when the 20ms, 60ms, and 80ms are configured. This embodiment is not limited.

The base station may also add information for indicating the time when the SL Gap appears together to the configuration information in step 302 to save signaling that the base station wastes by transmitting the two kinds of information through the additional configuration information.

When the configuration of the appearance period of the SL Gap is determined by the UE, the UE may read the appearance period of the SL Gap specified in the communication protocol; or, the UE may determine the appearance period of the SL Gap itself. When the UE determines the appearance period of the SL Gap, the UE may notify the base station of the occurrence period of the SL Gap, or may not notify the base station, which is not limited in this embodiment. The process of determining the appearance period of the SL Gap by the UE itself is the same as the process of configuring the appearance period of the SL Gap by the base station, and details are not described herein.

The UE also needs to determine the duration of the SL Gap. In a possible implementation, the length of time that the SL Gap is configured by the base station; in another possible implementation, when the UE determines the appearance period of the SL Gap Determine the duration of SL Gap. Wherein, when the UE determines the duration of the SL Gap, the UE can read the duration of the SL Gap specified in the communication protocol; or the UE can determine the duration of the SL Gap itself. When the UE determines the duration of the SL Gap, the UE may notify the base station of the duration of the SL Gap, or may not notify the base station, which is not limited in this embodiment.

Regardless of whether the configuration of the SL Gap is configured by the base station or determined by the UE, there is no need to consider whether the measurement of the gap between the Gap and the SL Gap conflicts, thereby reducing the requirements of configuring the measurement Gap and SL Gap, and improving the efficiency of configuring the Gap. Among them, measuring the conflict between Gap and SL Gap refers to measuring the time when the Gap appears and the time conflict of SL Gap. Please refer to the schematic diagram of measuring Gap and SL Gap shown in FIG. 3B, in which the third SL Gap conflicts with the second measurement Gap, and the fourth SL Gap conflicts with the third measurement Gap.

After determining the measurement of Gap and SL Gap, the UE performs timing, performs neighbor measurement during the time when the measurement Gap occurs, and transmits the data packet on the SL during the time when the SL Gap occurs. Since the measurement Gap and the SL Gap may collide, and the UE can only select one of the measurement Gap and the SL Gap at the same time, the UE performs the neighbor measurement in the measurement Gap or before transmitting the data packet on the SL through the SL Gap. It is also necessary to judge whether the measurement Gap and the SL Gap conflict.

Specifically, according to the time when the measurement Gap appears and the time when the SL Gap appears, it is judged whether the measurement Gap and the SL Gap conflict, including:

1) Determine the next measurement Gap corresponding to the current time according to the time when the measurement Gap appears. And the time period of the next SL Gap after the current time is determined according to the time when the SL Gap appears, determining whether the time period corresponding to the measurement gap overlaps with the time period of the SL Gap, and the minimum value of the time period corresponding to the measurement Gap is the measurement Gap. The time period, the maximum value of the time period corresponding to the measurement Gap is the sum of the time period for measuring the gap and the time period required for the UE to switch from measuring Gap to SL Gap; or

2) Determine the time period corresponding to the next SL Gap after the current time according to the time when the SL Gap appears, and determine the time period of the next measurement Gap after the current time according to the time when the measurement Gap appears, and determine the time period and measurement corresponding to the SL Gap. Whether the time period of Gap overlaps, the minimum value of the time period corresponding to SL Gap is the time period of SL Gap, the maximum value of the time period corresponding to SL Gap is the sum of the time period of SL Gap and the time period required for the UE to switch from SL Gap to measure Gap .

When a measurement gap occurs after the current time, the first time is obtained by positioning the first time length based on the start time of the measurement gap, and whether a SL Gap occurs in the time period determined by the detection start time and the first time. When a SL Gap appears in the time period, it is determined that the measurement Gap conflicts with the SL Gap; when there is no SL Gap in the time period, it is determined that the measurement Gap and the SL Gap do not conflict, and the first time is the smallest. The value is the duration of the measurement Gap. The maximum value is the duration of the measurement of the duration of the Gap plus the first predetermined duration. The first predetermined duration is the length of time required for the UE to switch from measuring Gap to SL Gap. In the actual implementation, the first predetermined duration may be set to 0.5 ms, or may be set to other values, which is not limited in this embodiment. or,

When a SL Gap occurs after the current time, the second time is obtained by positioning the second time based on the start time of the SL Gap, and whether a measurement Gap occurs during the time period determined by the detection start time and the second time. When a measurement Gap occurs during the time period, it is determined that the SL Gap conflicts with the measurement Gap; when a measurement Gap does not occur within the time period, it is determined that the SL Gap does not conflict with the measurement Gap, and the second time is minimum. The value is the duration of the SL Gap. The maximum value is the duration of the SL Gap plus the second predetermined duration. The second predetermined duration is the length of time required for the UE to switch from SL Gap to Gap. In the actual implementation, the second predetermined duration may be set to 0.5 ms, or may be set to other values, and the second predetermined duration is the same as or different from the first predetermined duration. This embodiment is not limited.

Step 306, when the measurement Gap collides with the SL Gap, the UE acquires the relative priority between the measurement Gap and the SL Gap, and the relative priority between the measurement Gap and the SL Gap is sent by the base station, or the measurement Gap and The relative priority between SL Gaps is determined by the UE.

In a possible implementation manner, the relative priority between the measurement Gap and the SL Gap is sent by the base station; in another possible implementation, the measurement between the Gap and the SL Gap is determined by the UE. For priority. Wherein, when the UE decides to measure the relative priority between the Gap and the SL Gap, the UE can read the relative priority between the measurement Gap and the SL Gap specified in the communication protocol; or the UE can decide to measure the Gap and the SL by itself. The relative priority between Gaps. When the UE determines to measure the relative priority between the Gap and the SL Gap, the UE may notify the base station of the relative priority between the Gap and the SL Gap, or may not notify the base station, which is not limited in this embodiment.

When the relative priority between the Gap and the SL Gap is sent by the base station, the method provided by the embodiment further includes: the base station sends a relative priority between the measurement Gap and the SL Gap to the UE, where the Gap and the SL Gap are measured. The relative priority between them is used to indicate that the UE chooses to measure the Gap or SL Gap.

Specifically, the base station and the UE agree that the base station delivers the high priority Gap or the low priority Gap. After that, the base station only needs to send the measurement Gap or SL Gap to the UE, and the UE can explicitly measure the Gap and the SL Gap. Relative priority between. For example, the base station and the UE agree that the base station delivers the high priority Gap, and when the base station sends the measurement Gap, the UE determines that the measurement Gap is a high priority with respect to the SL Gap; when the base station sends the SL Gap, The UE determines that the SL Gap is a high priority with respect to the measurement Gap. Alternatively, the base station separately calculates the priority values for the Gap and SL Gap measurements, and the UE compares the two values to determine the relative priority between the measurement Gap and the SL Gap. In this embodiment, the smaller the value is, the higher the priority is. For example, if the value of the priority configured by the base station for measuring Gap is 2, and the value of the priority configured for SL Gap is 3, the UE can determine the measurement Gap relative to the SL. Gap is a high priority. Of course, the base station can also perform the measurement of the relative priority between the Gap and the SL Gap in other manners, which is not limited in this embodiment.

Optionally, the base station may add the relative priority between the measurement Gap and the SL Gap to the configuration information in the step 302, and send the UE to the UE to save the relative relationship between the measurement Gap and the SL Gap by using the additional configuration information. Signaling wasted by priority.

Step 307, when the measurement Gap is higher priority than the SL Gap, the UE selects the measurement Gap, and step 308 is performed.

When the measurement Gap is high priority compared to SL Gap, it indicates that the importance of performing the neighbor cell measurement is higher than the importance of transmitting the data packet on the SL, at which time the UE chooses to measure the Gap.

In step 308, the UE performs neighbor cell measurement in the measurement Gap, and ends the process.

In step 309, when the measurement Gap is lower priority than the SL Gap, the UE selects SL Gap.

When the measurement Gap is lower priority than the SL Gap, it indicates that the importance of performing the neighbor cell measurement is lower than the importance of transmitting the data packet on the SL, at which time the UE selects the SL Gap.

In step 310, the UE transmits a data packet in the SL Gap.

In addition, by measuring the Gap or SL Gap according to the relative priority between the measurement Gap and SL Gap, it is possible to select the measurement Gap when measuring the Gap with respect to the SL Gap, and to measure the Gap with respect to the SL Gap. In the case of level, SL Gap is selected, so that the Gap selected by the UE meets the actual requirements, and the accuracy of the Gap selection is improved.

Referring to FIG. 4, a flowchart of still another method for selecting a Gap according to an embodiment of the present invention is shown. In this embodiment, a UE selects a measurement Gap or SL Gap according to a signal parameter of a serving cell of a UE. The Gap selection method may include:

In step 401, the base station determines a measurement Gap configured for the UE.

Step 402: The base station generates configuration information, where the configuration information is used to indicate the time when the measurement Gap appears.

Step 403: The base station sends configuration information to the UE.

Step 404: The UE receives configuration information sent by the base station.

Step 405: The UE determines, according to the time when the Gap is measured and the time when the SL Gap appears, whether the measurement Gap and the SL Gap conflict, and the time when the SL Gap appears is configured according to a predetermined policy.

The implementation process of the steps 401-405 is described in detail in steps 301-305, and details are not described herein.

Step 406: When the measurement Gap collides with the SL Gap, the UE acquires a signal parameter of the serving cell of the UE, where the signal parameter is signal strength or signal quality.

In this embodiment, whether the signal parameter is signal strength or signal quality may be pre-agreed by the base station and the UE. Among them, the signal strength and signal quality are used to indicate the quality of the signal of the serving cell. The technology for obtaining the signal strength or the signal quality of the UE is very mature, and is not described in this embodiment.

Step 407: The UE compares the signal parameter and the signal threshold, where the signal threshold is sent by the base station, or the signal threshold is determined by the UE.

The signal threshold is related to the signal parameter acquired by the UE. For example, when the signal parameter acquired by the UE is the signal strength, the signal threshold is the signal strength threshold; when the signal parameter acquired by the UE is For signal quality, the signal threshold is the signal quality threshold.

In a possible implementation, the signal threshold is sent by the base station; in another possible implementation, the signal threshold is determined by the UE. Wherein, when the signal threshold is determined by the UE, the UE may read the signal threshold specified in the communication protocol; or the UE may determine the signal threshold by itself. When the UE determines the signal threshold, the UE may notify the base station of the signal threshold, or may not notify the base station, which is not limited in this embodiment.

When the signal is sent by the base station, the method provided by the embodiment further includes: the base station sends a signal threshold to the UE, where the threshold is used to indicate that the UE selects the measurement Gap or SL Gap.

Optionally, the base station may add the signal threshold value to the configuration information in step 402 and send the signal to the UE to save the signaling that the base station wastes by sending the signal threshold value through the additional configuration information.

It should be noted that the UE can also obtain the signal strength and signal quality of the serving cell at the same time. The signal threshold at this time includes the signal strength threshold and the signal quality threshold, and the UE needs to set the signal strength and the signal strength threshold. The values are compared and the signal quality is compared to the signal quality threshold. In a possible implementation manner, when the signal strength is greater than the signal strength threshold or the signal quality is greater than the signal quality threshold, determining that the signal parameter is greater than the signal threshold; when the signal strength is less than the signal strength threshold and the signal quality When the signal quality threshold is less than, the signal parameter is determined to be smaller than the signal threshold. In another possible implementation manner, when the signal strength is greater than the signal strength threshold and the signal quality is greater than the signal quality threshold, determining that the signal parameter is greater than the signal threshold; when the signal strength is less than the signal strength threshold or signal When the quality is less than the signal quality threshold, it is determined that the signal parameter is less than the signal threshold.

Step 408: When the signal parameter is less than the signal threshold, the UE selects the measurement Gap, and performs step 409.

When the signal parameter is smaller than the signal threshold, it indicates that the serving cell signal is poor at this time, and the UE preferentially performs the neighboring cell measurement, so that when the signal of the neighboring cell is good, the neighboring cell is switched to the serving cell of the UE in time to ensure Normal communication of the UE.

In step 409, the UE performs neighbor cell measurement in the measurement Gap, and ends the process.

Step 410: When the signal parameter is greater than the signal threshold, the UE selects SL Gap.

When the signal parameter is greater than the signal threshold, it indicates that the serving cell signal is good at this time, and the UE does not have to preferentially perform neighbor cell measurement.

In step 411, the UE transmits a data packet in the SL Gap.

In summary, the Gap selection method provided by the embodiment of the present invention selects one of the measurement Gap and the SL Gap when the measurement Gap conflicts with the SL Gap; when the measurement Gap is selected, the measurement is performed. Neighbor measurement is performed in Gap; or, when SL Gap is selected, the data packet is transmitted in SL Gap, so that when the Gap and SL Gap collisions are measured, the UE can still perform neighbor measurement in the measurement Gap or in SL Gap. It is not necessary to configure the measurement Gap and SL Gap which are completely staggered from each other, thereby solving the measurement Gap and SL Gap which are completely staggered from each other, which makes the configuration of Gap difficult and the configuration efficiency is low, and the efficiency of configuring Gap is improved. Effect.

In addition, by selecting the measurement Gap or SL Gap according to the signal parameter of the serving cell of the UE, when the signal of the serving cell is poor, the measurement Gap can be selected to preferentially perform the neighboring cell measurement, and when the signal of the neighboring cell is good, timely The neighboring cell is switched to the serving cell of the UE to ensure normal communication of the UE.

Referring to FIG. 5, a flowchart of still another method for selecting a Gap according to an embodiment of the present invention is shown. In this embodiment, a UE selects a measurement Gap or SL Gap according to a priority of a data packet. The Gap selection method may include:

In step 501, the base station determines a measurement Gap configured for the UE.

Step 502: The base station generates configuration information, where the configuration information is used to indicate a time when the measurement Gap appears.

Step 503: The base station sends configuration information to the UE.

Step 504: The UE receives configuration information sent by the base station.

Step 505: The UE determines, according to the time when the Gap is measured and the time when the SL Gap appears, whether the measurement Gap and the SL Gap conflict, and the time when the SL Gap appears is configured according to a predetermined policy.

The implementation process of the steps 501-505 is described in detail in steps 301-305, and details are not described herein.

Step 506, when the measurement Gap collides with the SL Gap, the UE acquires the priority of the data packet.

A packet is a packet that will be transmitted on the SL through SL Gap. The priority of the data packet may be represented by a numerical value, for example, the value of the priority of the data packet is 1, or the value of the priority of the data packet is 4 or the like, which is not limited in this embodiment. The technology for the UE to obtain the priority of the data packet is very mature, and is not described in this embodiment.

Step 507: The UE compares the priority of the data packet with the data packet priority threshold, and the data packet priority threshold is sent by the base station, or the data packet priority threshold is determined by the UE.

In a possible implementation manner, the data packet priority threshold is sent by the base station; in another possible implementation, the data packet priority threshold is determined by the UE. The UE may read the packet priority threshold specified in the communication protocol when the UE determines the packet priority threshold. Alternatively, the UE may determine the packet priority threshold. When the UE itself determines the packet priority gate In the limit, the UE may notify the base station of the packet priority threshold, or may not notify the base station, which is not limited in this embodiment.

When the data packet priority threshold is sent by the base station, the method provided by the embodiment further includes: the base station sends a data packet priority threshold to the UE, where the data packet priority threshold is used to indicate that the UE selects the measurement. Gap or SL Gap.

Optionally, the base station may add the data packet priority threshold to the configuration information in step 502 and send the signal to the UE to save the signaling that the base station wastes by sending the data packet priority threshold by using the additional configuration information.

Assume that the smaller the value, the higher the priority, and the priority value of the packet is 2, and the packet priority threshold is 3, then the priority of the packet is higher than the packet priority threshold; When the level threshold is 1, the priority of the packet is lower than the packet priority threshold.

Step 508: When the priority of the data packet is lower than the data packet priority threshold, the UE selects the measurement Gap, and performs step 509.

When the priority of the data packet is lower than the packet priority threshold, it indicates that the data packet to be transmitted on the SL is not very urgent, and the UE prefers to measure the Gap.

In step 509, the UE performs neighbor cell measurement in the measurement Gap, and ends the process.

Step 510: When the priority of the data packet is higher than the data packet priority threshold, the UE selects SL Gap.

When the priority of the packet is higher than the packet priority threshold, it indicates that the packet to be transmitted on the SL is urgent, and the UE prefers SL Gap.

In step 511, the UE transmits a data packet in the SL Gap.

In addition, by selecting the measurement measurement Gap or SL Gap according to the priority of the data packet, it can be determined that the data packet to be transmitted on the SL through the SL Gap is urgent when the priority of the data packet is higher than the data packet priority threshold. At this time, SL Gap is preferred to ensure the normal operation of the business.

Referring to FIG. 6, which is a flowchart of a method for selecting a Gap selection method according to an embodiment of the present invention. In this embodiment, the UE selects whether the data packet belongs to public security (English: Public Safety; PS: service selection). Measurements measure Gap or SL Gap. The Gap selection method may include:

In step 601, the base station determines a measurement Gap configured for the UE.

Step 602: The base station generates configuration information, where the configuration information is used to indicate a time when the measurement Gap appears.

Step 603: The base station sends configuration information to the UE.

Step 604: The UE receives configuration information sent by the base station.

Step 605: The UE determines, according to the time when the Gap is measured and the time when the SL Gap appears, whether the measurement Gap and the SL Gap conflict, and the time when the SL Gap appears is configured according to a predetermined policy.

The implementation process of steps 601-605 is described in detail in steps 301-305, and details are not described herein.

Step 606: When the measurement Gap collides with the SL Gap, the UE determines whether the data packet belongs to the PS service.

Among them, the PS service refers to the business involving public safety. For example, the PS service includes military communication services; the non-PS service includes civil or commercial communication services.

When it is determined whether the data packet belongs to the PS service, in a possible implementation manner, the UE determines, according to its own attribute, whether the data packet belongs to the PS service, for example, when the UE is a military walkie-talkie, all data packets transmitted by the UE are Belongs to the PS business. In another possible implementation manner, the UE determines, according to the attribute of the data packet, whether the data packet belongs to the PS service, for example, the UE reads the destination Internet address (English: Internet Protocol; IP) and the destination port of the data packet. Detecting whether the destination IP address and the destination port are the destination IP address and the destination port used in the PS service. When the destination IP address and the destination port are the destination IP address and the destination port used in the PS service, it is determined that the data packet belongs to the PS service. When the destination IP address and the destination port are not the destination IP address and the destination port used in the PS service, it is determined that the data packet does not belong to the PS service. Certainly, the UE may determine, by other means, whether the data packet belongs to the PS service, which is not limited in this embodiment.

Step 607: When the data packet does not belong to the PS service, the UE selects the measurement Gap, and step 608 is performed.

When the data packet does not belong to the PS service, it indicates that the data packet that needs to be transmitted on the SL is not very urgent, and the UE prefers to measure the Gap.

In step 608, the UE performs neighbor cell measurement in the measurement Gap, and ends the process.

Step 609, when the data packet belongs to the PS service, the UE selects the SL Gap.

When the data packet belongs to the PS service, it indicates that the data packet that needs to be transmitted on the SL is urgent, and the UE prefers SL Gap.

In step 610, the UE transmits a data packet in the SL Gap.

In summary, the Gap selection method provided by the embodiment of the present invention selects one of the measurement Gap and the SL Gap when the measurement Gap conflicts with the SL Gap; when the measurement Gap is selected, the neighboring area is measured in the measurement Gap. Measurement; or, when SL Gap is selected, the data packet is transmitted in SL Gap, so that when the Gap and SL Gap collisions are measured, the UE can still perform neighbor cell measurement in the measurement Gap or transmit the data packet in the SL Gap, without In order to configure the Gap and SL Gap which are completely staggered from each other, the Gap and SL Gap which are completely misaligned with each other are solved, which makes the configuration of the Gap difficult and the configuration efficiency low, and the effect of improving the efficiency of configuring the Gap is achieved.

In addition, by selecting whether to measure the measurement gap or SL Gap according to whether the data packet to be transmitted in the SL Gap belongs to the PS service, it can be determined that the data packet to be transmitted on the SL through the SL Gap is urgent when the data packet belongs to the PS service. SL Gap is preferred in order to ensure the normal operation of the business.

Referring to FIG. 7, a flowchart of a method for selecting a Gap selection method according to an embodiment of the present invention is shown. In this embodiment, the UE selects a measurement Gap according to whether the frequency of the neighboring cell belongs to a reduced performance group. Or SL Gap. The Gap selection method may include:

In step 701, the base station determines a measurement Gap configured for the UE.

Step 702: The base station generates configuration information, where the configuration information is used to indicate a time when the measurement Gap appears.

Step 703: The base station sends configuration information to the UE.

Step 704: The UE receives configuration information sent by the base station.

Step 705: The UE determines, according to the time when the Gap is measured and the time when the SL Gap appears, whether the measurement Gap and the SL Gap conflict, and the time when the SL Gap appears is configured according to a predetermined policy.

The implementation process of steps 701-705 is described in detail in steps 301-305, and details are not described herein.

Step 706: When the measurement Gap collides with the SL Gap, the UE determines whether the frequency of the neighboring cell belongs to the reduction performance group, and the reduction performance group is a frequency packet with the worst delay performance among the frequency groups, and the frequency packet is required for the UE. The measured frequencies are grouped.

Measurements of frequencies in the depletion performance group are generally not measurements of mobility services. For example, the frequency in the reduction performance group is measured to find a cell to be unloaded or to find an AP that can be accessed. Since the measurement of the frequency in the reduction performance group is not used to find the switchable neighboring cell, it is generally not urgent to measure the frequency in the performance reduction group. The UE can determine whether the frequency of the neighboring cell belongs to the reduction performance group. Choose to measure Gap or SL Gap.

Generally, the base station sends measurement configuration information to the UE, where the measurement configuration information includes at least one measurement. The frequency is measured, and each measurement frequency belongs to one of two frequency groups. One of the two frequency groups is a reduction performance group, and the other is a normal performance group. In a specific implementation, the UE may first determine the frequency of the neighboring cell to be measured in the measurement Gap, determine the frequency packet to which the frequency belongs, and determine whether the frequency of the neighboring cell belongs to the reduction performance group according to the frequency group to which it belongs.

Step 707: When the frequency does not belong to the reduction performance group, the UE selects the measurement Gap, and performs step 708.

When the frequency of the neighboring cell does not belong to the performance reduction group, it indicates that the UE may look for a switchable neighboring cell through the neighboring cell measurement. The signal quality of the serving cell may be poor. The UE preferentially measures the Gap for neighboring cell measurement. When the signal of the neighboring cell is good, the neighboring cell is switched to the serving cell of the UE in time to ensure normal communication of the UE.

In step 708, the UE performs neighbor cell measurement in the measurement Gap, and ends the process.

Step 709: When the frequency of the neighboring cell belongs to the reduction performance group, the UE selects SL Gap.

When the frequency of the neighboring cell belongs to the performance reduction group, it indicates that the neighboring cell measurement is not very urgent, and the UE selects SL Gap.

In step 710, the UE transmits a data packet in the SL Gap.

In addition, by selecting whether to measure the Gap or the SL Gap according to whether the frequency of the neighboring cell belongs to the performance reduction group, it may be determined that the UE may find the switchable neighbor cell through the neighbor cell measurement when the frequency of the neighboring cell does not belong to the performance reduction group. At this time, the signal quality of the serving cell may be poor. The UE preferentially measures the gap to measure the neighboring cell, so that when the signal of the neighboring cell is good, the neighboring cell is switched to the serving cell of the UE in time to ensure normal communication of the UE.

Referring to FIG. 8, which is a flowchart of a method for selecting a Gap selection method according to an embodiment of the present invention. In this embodiment, the UE selects a Gap according to whether the SL Gap is used to receive a data packet or is used to send a data packet. SL Gap. The Gap selection method may include:

In step 801, the base station determines a measurement Gap configured for the UE.

Step 802: The base station generates configuration information, where the configuration information is used to indicate the time when the measurement Gap appears.

Step 803: The base station sends configuration information to the UE.

Step 804: The UE receives configuration information sent by the base station.

Step 805: The UE determines, according to the time when the Gap is measured and the time when the SL Gap appears, whether the measurement Gap and the SL Gap conflict, and the time when the SL Gap appears is configured according to a predetermined policy.

The implementation process of steps 801-805 is described in detail in steps 301-305, and details are not described herein.

Step 806, when the measurement Gap collides with the SL Gap, the UE determines whether the SL Gap is used to receive the data packet or is used to send the data packet, and the SL Gap is used to receive the data packet or to send the data packet as indicated by the base station, or Whether the SL Gap is used to receive data packets or to send data packets is determined by the UE.

In a possible implementation, the base station indicates whether the SL Gap is used to receive the data packet or is used to send the data packet. In another possible implementation manner, the UE determines whether the SL Gap is used to receive the data packet or To send a packet. Wherein, when the UE determines whether the SL Gap is used to receive the data packet or is used to send the data packet, the UE can read whether the SL Gap specified in the communication protocol is used to receive the data packet or to send the data packet; or, the UE can It determines whether SL Gap is used to receive data packets or to send data packets. When the UE determines whether the SL Gap is used to receive the data packet or is used to send the data packet, the UE may use the SL Gap to receive the data packet or use the data packet to notify the base station, or may not notify the base station, which is not used in this embodiment. limited.

When the base station indicates that the SL Gap is used to receive the data packet or is used to send the data packet, the method provided by the embodiment further includes: the base station indicating to the UE whether the SL Gap is used to receive the data packet or to send the data packet, SL Whether Gap is used to receive data packets or to send data packets is used to instruct the UE to choose to measure Gap or SL Gap.

Optionally, the base station may indicate, by using the configuration information in step 802, whether the SL Gap is used to receive the data packet or to send the data packet, so as to save the base station from using additional configuration information to indicate whether the SL Gap is used to receive the data packet or to send the data packet. Signaling wasted by the packet.

In this embodiment, the UE may select to measure the Gap when the SL Gap is used to receive the data packet, and select the SL Gap when the SL Gap is used to send the data packet; the UE may also use the measurement Gap in the SL Gap to send the data packet. SL Gap is used to select SL Gap when receiving packets. In a possible implementation manner, the foregoing selection rule is sent by the base station; in another possible implementation manner, the foregoing selection rule is determined by the UE. Wherein, when the selection rule is determined by the UE, the UE may read the foregoing selection rule specified in the communication protocol; or the UE may determine the selection rule by itself. When the UE determines the above selection rule, the UE may notify the base station of the foregoing selection rule, or may not notify the base station, The embodiment is not limited.

When multiple UEs communicate with each other on the SL at the same time, since only one UE can be sent to transmit data packets at the same time, other UEs receive data packets, and the duration of each UE transmitting data packets is far less than the duration of receiving data packets. Therefore, the importance of transmitting the data packet is higher than the importance of receiving the data packet. Preferably, the UE selects the measurement Gap when the SL Gap is used to receive the data packet, and selects the SL Gap when the SL Gap is used to send the data packet. Ensure the normal transmission of data packets.

In order to facilitate the understanding of the duration of the transmitted data packet and the duration of the received data packet, the present embodiment uses the SL communication for 10 minutes between the five UEs as an example. The duration of each data packet sent by each UE is 2 minutes. The duration of receiving the packet is 8 minutes.

Step 807, when the SL Gap is used to receive the data packet, the UE selects the measurement Gap, and performs step 808.

In step 808, the UE performs neighbor cell measurement in the measurement Gap, and ends the process.

Step 809, when SL Gap is used to send a data packet, the UE selects SL Gap.

In step 810, the UE transmits a data packet in the SL Gap.
