[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This disclosure claims priority to Chinese patent application number 2023111948721, filed on September 15, 2023, entitled “Method and device for determining gap GAP parameters,” which is incorporated herein by reference in its entirety. Technical Field

[0003] The present disclosure relates to the field of communication technology, and in particular to a method and device for determining a gap (GAP) parameter. Background Art

[0004] In the New Radio (NR) system, the terminal periodically detects the frequencies of its serving cell and adjacent cells and reports the detection results to the network device. The network device then determines the signal quality of the serving cell and adjacent cells based on the detection results, thereby controlling whether the terminal performs cell switching based on the signal quality of the serving cell and adjacent cells.

[0005] Based on the existing NR protocol, before a terminal detects the frequencies of its serving cell and neighboring cells, it usually needs to first receive the GAP parameters configured by the network device, and then perform frequency detection based on the GAP parameters configured by the network device.

[0006] In the prior art, when network devices configure GAP parameters for terminals, they do not consider the impact of inconsistent frame header offsets at different frequencies on the configured GAP parameters. This can cause the terminal to be unable to perform frequency detection based on the configured GAP parameters, thereby affecting the mobility of the terminal in the connected state.

[0125] In the embodiments of the present disclosure, the term "and / or" describes the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0126] In the embodiments of the present disclosure, the term "plurality" refers to two or more than two, and other quantifiers are similar thereto.

[0127] The technical solutions provided by the embodiments of the present disclosure can be applied to a variety of systems, such as 5G systems.

[0128] The terminal involved in the embodiments of the present disclosure may refer to a device that provides voice and / or data connectivity to a user, a handheld device with wireless connection capabilities, or other processing devices connected to a wireless modem. In different systems, the name of the terminal may also be different. For example, in a 5G system, the terminal may be called User Equipment (UE). A wireless terminal device can communicate with one or more core networks (CN) via a radio access network (RAN). The wireless terminal device can be a mobile terminal device, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal device. For example, it can be a portable, pocket-sized, handheld, computer-built-in, or vehicle-mounted mobile device that exchanges voice and / or data with a radio access network. For example, Personal Communication Service (PCS) phones, cordless phones, Session Initiated Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), and other devices. The wireless terminal device may also be referred to as a system, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, a remote terminal device, an access terminal device, a user terminal device, a user agent, or a user device, but is not limited in the embodiments of the present disclosure.

[0129] The network device involved in the embodiments of the present disclosure may be a base station, which may include multiple cells providing services to terminals. Depending on the specific application scenario, the base station may also be called an access point, or may be a device in an access network that communicates with a wireless terminal device through one or more sectors on an air interface, or may be called another name. The network device may be used to interchange received air frames with Internet Protocol (IP) packets, acting as a router between the wireless terminal device and the rest of the access network, wherein the rest of the access network may include an Internet Protocol (IP) communication network. The network device may also coordinate the attribute management of the air interface. For example, the network device involved in the embodiments of the present disclosure may be a base transceiver station (BTS) in the Global System for Mobile communications (GSM) or code division multiple access (CDMA), a network device (NodeB) in wide-band code division multiple access (WCDMA), an evolutionary Node B (eNB or e-NodeB) in the long term evolution (LTE) system, a 5G base station (gNB) in the 5G network architecture (next generation system), a home evolved Node B (HeNB), a relay node, a femto, a pico, etc., and is not limited in the embodiments of the present disclosure. In some network structures, the network device may include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit may also be geographically separated.

[0130] For example, in an embodiment of the present disclosure, a network device and a terminal device may each use one or more antennas for multiple-input multiple-output (MIMO) transmission. MIMO transmission may be single-user MIMO (SU-MIMO) or multi-user MIMO (MU-MIMO). Depending on the form and number of antenna combinations, MIMO transmission may be 2D-MIMO, 3D-MIMO, FD-MIMO, or massive-MIMO, or may be diversity transmission, precoded transmission, or beamforming transmission.

[0131] In the New Radio (NR) system, the terminal periodically detects the frequencies of its serving cell and neighboring cells and reports the detection results to the network device, which then determines the signal quality of the serving cell and neighboring cells based on the detection results. If the signal quality of the reference signal of the neighboring cell is lower than the specified signal quality threshold, the terminal is instructed to continue to reside in the serving cell; conversely, if the signal quality of the reference signal of the neighboring cell is higher than the specified signal quality threshold, the terminal is instructed to switch from the serving cell to the neighboring cell to ensure that the terminal always resides in the cell with a better reference signal.

[0132] Based on the existing NR protocol, the terminal usually needs to first receive the GAP parameters configured by the network device, and then perform frequency detection based on the GAP parameters configured by the network device. Among them, the GAP parameters mainly include GapMgl, GapMgrp, GapOffset, and GapMgta. GapMgl indicates the GAP measurement duration, GapMgrp indicates the GAP period, GapOffset indicates the GAP starting position, and GapMgta indicates the GAP radio frequency switching timing.

[0133] It is understood that, in addition to the above four parameters, the GAP parameters may also include other parameters, which may be set according to actual needs. In the subsequent description, the GAP parameters including GapMgl, GapMgrp, GapOffset, and GapMgta will be described as an example.

[0134] In the prior art, when configuring GAP parameters for terminals, network devices fail to consider the impact of inconsistent frame header offsets across different frequencies on the configured GAP parameters. This can result in the terminal being unable to perform frequency detection based on the configured GAP parameters, thus affecting the terminal's mobility in a connected state.

[0135] Specifically, in the prior art, in the process of determining the values ​​of GapMgl and GapMgrp, these two parameters are used as a combined parameter, called GapPattern, to determine the values ​​of GapMgl and GapMgrp together.

[0136] In the presence of heterogeneous system frequencies, a GapPattern with a GapMgl value of 6ms among the preset multiple GapPatterns can be determined as multiple candidate GapPatterns; then, based on the longest GapMgrp and the shortest GapMgl among the multiple candidate GapPatterns, the final GapPattern is determined from the multiple candidate GapPatterns, and the GapMgl and GapMgrp in the final GapPattern are the determined GapMgl and GapMgrp.

[0137] In the presence of heterodyne frequency points, the value of GapMgl can be determined based on GapMgl>=(SmtcDuration+2*GapMgta). Assuming that the value of GapMgl is Ams, the GapPattern with the GapMgl value of Ams among the preset multiple GapPatterns is determined as multiple candidate GapPatterns, and then the final GapPattern is determined from the multiple candidate GapPatterns based on the longest GapMgrp and the shortest GapMgl among the multiple candidate GapPatterns. The GapMgl and GapMgrp in the final GapPattern are the determined GapMgl and GapMgrp.

[0138] Through the above description, the values ​​of GapMgl and GapMgrp can be determined. When determining the value of GapOffset, the value of GapOffset can be determined according to SmtcIndex*SmtcPeriod+(SmtcOffset+SmtcPeriod-GapOffsetIndex)%SmtcPeriod.

[0139] Among them, SmtcIndex indicates the SMTC period index within the GAP period, SmtcPeriod indicates the SMTC period, SmtcOffset indicates the SMTC starting position, GapOffsetIndex indicates the available GapOffset position index within the SMTC measurement period, and SMTC is SSB Measurement Timing Configuration.

[0140] The SmtcIndex range is [0, GapMgrp / SmtcPeriod-1] and indicates the index of the SMTC period within the GAP period. Typically, the GAP period is greater than the SMTC period and they are multiples of each other. The GapOffsetIndex range is [0, GapMgl–SmtcDuration–2*GapMgta] and indicates the index of the available GapOffset positions within an SMTC measurement period.

[0141] When determining GapMgta, considering that the value of GapMgta is the same as the RF conversion time, the value of GapMgta is fixedly configured to be 0.5ms.

[0142] Based on the above description, the values ​​of GAP parameters including GapMgl, GapMgrp, GapOffset, and GapMgta can be determined. If multiple GapOffsets exist, it is necessary to consider the discrete configuration of GAPs between users in the cell, and try to stagger the scheduling timing of different users. Specifically, the discrete configurations between SMTC cycles are prioritized, followed by discrete configurations within the SMTC cycle. Within the discrete SMTC interval, the GapOffset with the smallest number of users is selected as the final GapOffset to determine the GAP parameters.

[0143] For easier understanding, an example of existing GAP parameter configuration is given. In this example, assuming that inter-frequency point 1: the frame header offset is configured as 0, SmtcPeriod = 20ms, SmtcOffset = 0ms, SmtcDuration = 2ms; inter-frequency point 2: the frame header offset is configured as 3ms, SmtcPeriod = 20ms, SmtcOffset = 0ms, SmtcDuration = 2ms, then the existing GAP parameter configuration method is adopted, and the impact of inconsistent frame header offsets between inter-frequency points 1 and 2 on the configured GAP parameters is not considered. The calculated GapOffset can be shown in Figure 1. Figure 1 is a schematic diagram of a GapOffset configuration provided by the prior art. The GapOffset is configured as 47ms, 48ms, 49ms, and 0ms. At any of the GapOffset positions, only the measurement of inter-frequency point 1 can be achieved, while the measurement of inter-frequency point 2 cannot be achieved. This will cause the terminal to be unable to perform frequency detection based on the configured GAP parameters, thereby affecting the mobility of the terminal in the connected state.

[0144] In order to fully consider the impact of inconsistent frame header offsets of different frequency points on the configured GAP parameters, so that the terminal can accurately perform frequency detection based on the configured GAP parameters, in the embodiment of the present disclosure, the SmtcOffset of each frequency point can be uniformly converted into an inter-frequency SMTC starting position based on the Global Positioning System (GPS), and the GPS-based inter-frequency SMTC starting position of each frequency point can be obtained, which can be recorded as AbsSmtcOffset, and the GAP parameters can be determined based on the GPS-based inter-frequency SMTC starting position of each frequency point.

[0145] It can be seen that by determining the GPS-based inter-frequency SMTC starting position of each frequency point and determining the GAP parameters based on the GPS-based inter-frequency SMTC starting position of each frequency point, the influence of inconsistent frame header offsets of different frequency points on the configured GAP parameters can be avoided to a certain extent, so that the determined GAP parameters can cover the measurement time domain positions of all inter-frequency points as much as possible, so that the terminal can accurately perform frequency detection based on the configured GAP parameters.

[0146] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure and not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present disclosure.

[0147] FIG2 is a flow chart of a method for determining a gap GAP parameter provided by an embodiment of the present disclosure. The method for determining a gap GAP parameter can be applied to a network device. For example, referring to FIG2 , the method for determining a gap GAP parameter may include:

[0148] S201: Determine an inter-frequency SMTC starting position of each of a plurality of frequency points to be detected, wherein at least two of the plurality of frequency points to be detected have different frame header offsets, and the inter-frequency SMTC starting position is determined based on a global positioning system (GPS).

[0149] In the embodiment of the present disclosure, precisely because of the impact of inconsistent frame header offsets of different frequency points on the configuration of GAP parameters, when configuring GAP parameters, the SmtcOffset of multiple frequency points to be detected is uniformly converted into the GPS-based heterofrequency SMTC starting position, so as to avoid the impact of inconsistent frame header offsets of different frequency points on the configuration of GAP parameters to a certain extent.

[0150] After determining the respective inter-frequency SMTC starting positions of the multiple frequency points to be detected, the following S202 may be executed:

[0151] S202. Determine target combination parameters and target GAP starting position based on the respective inter-frequency SMTC starting positions of multiple frequency points to be detected. The target combination parameters include target GAP measurement duration and target GAP period. The GAP parameters include target GAP measurement duration, target GAP period and target GAP starting position.

[0152] For example, in the embodiment of the present disclosure, the GAP parameters include the target GAP measurement duration, the target GAP period, and the target GAP starting position, and may also include the GAP radio frequency switching timing, which can be specifically set according to actual needs.

[0153] It should be noted that in the embodiment of the present disclosure, unlike the existing GAP radio frequency switching timing which is fixed at 0.5ms, the GAP radio frequency switching timing can be configured to 0ms, 0.25ms, and 0.5ms, and the GAP time domain position can be adjusted within a finer time domain range, including STMC with different frame header offsets.

[0154] It can be seen that in the embodiment of the present disclosure, when determining the GAP parameters, the starting position of the hetero-frequency SMTC of each of the multiple frequency points to be detected can be determined first, and there are at least two frequency points with different frame header offsets among the multiple frequency points to be detected, and the hetero-frequency SMTC starting position is determined based on GPS; then, based on the hetero-frequency SMTC starting position of each of the multiple frequency points to be detected, the target combination parameters and the target GAP starting position are determined, and the target combination parameters include the target GAP measurement duration and the target GAP period; the GAP parameters include the target GAP measurement duration, the target GAP period and the target GAP starting position. In this way, by determining the GAP parameters based on the hetero-frequency SMTC starting position of each of the multiple frequency points to be detected, the influence of inconsistent frame header offsets of different frequency points on the configured GAP parameters can be avoided to a certain extent, so that the determined GAP parameters can cover the measurement time domain positions of all hetero-frequencies as much as possible, so that the terminal can accurately perform frequency detection based on the configured GAP parameters.

[0155] Based on the embodiment shown in FIG2 above, in order to facilitate understanding of how to determine the target combination parameters and the target GAP starting position based on the respective hetero-frequency SMTC starting positions of multiple frequency points to be detected in the embodiment of the present disclosure, the embodiment shown in FIG3 will be described in detail below.

[0156] FIG3 is a flow chart of determining a target combination parameter and a target GAP starting position according to an embodiment of the present disclosure. The method can be applied to a network device. For example, referring to FIG2 , the method may include:

[0157] S301. Determine the initial combination parameters based on the respective inter-frequency SMTC starting positions of the multiple frequency points to be detected, and determine the multiple candidate GAP starting positions corresponding to the multiple frequency points to be detected based on the respective inter-frequency SMTC starting positions of the multiple frequency points to be detected, the GAP RF conversion timing and the initial combination parameters. The initial combination parameters include the initial GAP measurement duration and the initial GAP period.

[0158] For example, in the embodiment of the present disclosure, based on the respective inter-frequency SMTC starting positions of multiple frequency points to be detected, determining the initial combination parameters, that is, determining the initial GAP measurement duration and the initial GAP period, may include two possible scenarios:

[0159] In one possible scenario, multiple frequencies to be detected include frequencies from different systems. When determining the initial combination parameters, a combination parameter with a GapMgl value of 6ms among the preset multiple combination parameters GapPattern is used as a multiple candidate combination parameter. Each candidate combination parameter includes a candidate GAP measurement duration and a candidate GAP period. A target combination parameter is then determined from the multiple candidate combination parameters based on the longest GAP period.

[0160] For example, in the embodiment of the present disclosure, the preset multiple combination parameters can be seen in the following Table 1:

[0161] Table 1

[0162] As shown in Table 1 above, the number of preset multiple combination parameters can be 24. Among the 24 combination parameters GapPattern, the combination parameter with the value of GapMgl being 6ms is determined as multiple candidate combination parameters, and the multiple candidate combination parameters are combination parameters with combination parameter identifiers of 0, 1, 4 and 5.

[0163] In another possible scenario, there are inter-frequency frequencies among the multiple frequencies to be detected. When determining the initial combination parameters, multiple candidate combination parameters can be determined based on the inter-frequency SMTC starting positions of the multiple frequencies to be detected and the preset GAP RF conversion timing. Each candidate combination parameter includes a candidate GAP measurement duration and a candidate GAP period. Then, based on the longest GAP period included in the multiple candidate combination parameters, the target combination parameters are determined from the multiple candidate combination parameters.

[0164] The GAP parameters also include a GAP radio frequency switching timing.

[0165] For example, in this possible scenario, based on the respective inter-frequency SMTC starting positions of multiple frequency points to be detected and the preset GAP RF conversion timing, when determining multiple candidate combination parameters, the value of GapMgl can be determined based on GapMgl>=(SmtcDuration+2*GapMgta), and based on the value of GapMgl, multiple candidate combination parameters are determined from the preset multiple combination parameters GapPattern. Among them, the preset multiple combination parameters can be seen in Table 1 and will not be repeated here.

[0166] In combination with any of the above possible scenarios, when determining the target combination parameter from multiple candidate combination parameters based on the longest GAP period included in multiple candidate combination parameters, the number of candidate combination parameters including the longest GAP period can be determined first; when the number of candidate combination parameters is one, the candidate combination parameter including the longest GAP period can be directly determined as the initial combination parameter; when the number of candidate combination parameters is multiple, the candidate combination parameter corresponding to the shortest GAP measurement duration among the candidate combination parameters including the longest GAP period is determined as the initial combination parameter.

[0167] The GAP measurement duration in the initial combination parameters is the initial GAP measurement duration; the GAP period in the initial combination parameters is the initial GAP period, thereby determining the initial GAP measurement duration and the initial GAP period.

[0168] For example, the multiple candidate combination parameters include combination parameters with combination parameter identifiers of 0, 1, 4, and 5, namely, combination parameter 0, combination parameter 1, combination parameter 4, and combination parameter 5. In combination parameter 0, the GAP measurement duration is 6, and the GAP period is 40; in combination parameter 1, the GAP measurement duration is 6, and the GAP period is 80; in combination parameter 4, the GAP measurement duration is 6, and the GAP period is 20; and in combination parameter 5, the GAP measurement duration is 6, and the GAP period is 160. The longest GAP period is 160, and the candidate combination parameter including the longest GAP period 160 is combination parameter 5. Therefore, combination parameter 5 can be directly determined as the initial combination parameter.

[0169] For another example, the multiple candidate combination parameters include combination parameters with combination parameter identifiers of 0, 1, 3, and 4, namely, combination parameter 0, combination parameter 1, combination parameter 3, and combination parameter 4. In combination parameter 0, the GAP measurement duration is 6 and the GAP period is 40; in combination parameter 1, the GAP measurement duration is 6 and the GAP period is 80; in combination parameter 3, the GAP measurement duration is 3 and the GAP period is 80; and in combination parameter 4, the GAP measurement duration is 6 and the GAP period is 20. The longest GAP period is 80, and the candidate combination parameters that include the longest GAP period 80 are combination parameter 1 and combination parameter 3. In this case, the shortest GAP measurement duration between combination parameter 1 and combination parameter 3 is further determined, and the shortest GAP measurement duration is 3. Combination parameter 1, which includes the shortest GAP measurement duration 3, is determined as the initial combination parameter.

[0170] In combination with the above description, the GAP measurement duration in the initial combination parameters is the initial GAP measurement duration; the GAP period in the initial combination parameters is the initial GAP period, thereby determining the initial GAP measurement duration and the initial GAP period.

[0171] For example, in an embodiment of the present disclosure, when determining multiple candidate GAP starting positions corresponding to each of the multiple frequency points to be detected based on the respective inter-frequency SMTC starting positions, GAP radio frequency conversion timings, and initial combination parameters of the multiple frequency points to be detected, the configuration granularity of the GAP measurement can be appropriately relaxed. The existing technology can only configure the GAP measurement interval with an accuracy of 1ms. In an embodiment of the present disclosure, by flexibly configuring the GAP radio frequency conversion timing, that is, the GapMgta configuration, the GAP measurement interval can be configured with an accuracy of 0.5ms. At the same time, the calculation of the candidate GAP starting position takes into account the influence of the inter-frequency frame header offset, as follows:

[0172] For each frequency point to be detected, the minimum value of the GAP starting position is determined based on the inter-frequency SMTC starting position of the frequency point to be detected, the GAP RF conversion duration of the frequency point to be detected, the GAP RF conversion timing and the initial combination parameters; and the maximum value of the GAP starting position is determined based on the inter-frequency SMTC starting position of the frequency point to be detected, the GAP RF conversion duration and the initial GAP period; and then based on the SMTC period index, the SMTC period, the minimum value of the GAP starting position and the maximum value of the GAP starting position, multiple candidate GAP starting positions corresponding to the frequency point to be detected are jointly determined.

[0173] The minimum value of the GAP starting position can be understood as the configuration lower limit of the GAP starting position, and the maximum value of the GAP starting position can be understood as the configuration upper limit of the GAP starting position.

[0174] For example, in the embodiment of the present disclosure, when determining the minimum value of the GAP starting position based on the inter-frequency SMTC starting position of the frequency to be detected, the GAP RF conversion duration of the frequency to be detected, the GAP RF conversion timing and the initial combination parameters, the minimum value of the GAP starting position can be determined based on GapOffsetMin = (AbsSmtcOffset + SmtcDuration + RfSwitchTime + GapMgta - GapMgl + GapMgrp) mod GapMgrp, thereby calculating the minimum value of the GAP starting position.

[0175] Among them, GapOffsetMin represents the minimum value of the GAP starting position, AbsSmtcOffset represents the starting position of the inter-frequency SMTC, SmtcDuration represents the SMTC duration, RfSwitchTime represents the GAP radio frequency switching duration, GapMgta represents the GAP radio frequency switching timing, GapMgl represents the initial GAP measurement duration, and GapMgrp represents the initial GAP period.

[0176] For example, in an embodiment of the present disclosure, when determining the maximum value of the GAP starting position based on the inter-frequency SMTC starting position of the frequency point to be detected, the GAP RF conversion time and the initial GAP period, the maximum value of the GAP starting position can be determined based on GapOffsetMax = (AbsSmtcOffset-RfSwitchTime+GapMgta+GapMgrp) mod GapMgrp, thereby calculating the maximum value of the GAP starting position.

[0177] Among them, GapOffsetMax indicates the maximum value of the GAP starting position, AbsSmtcOffset indicates the starting position of the inter-frequency SMTC, RfSwitchTime indicates the GAP radio frequency switching duration, GapMgta indicates the GAP radio frequency switching timing, and GapMgrp indicates the initial GAP period. For example, the GAP radio frequency switching duration can be set to 0.5ms, which can be set according to actual needs.

[0178] For example, in an embodiment of the present disclosure, when determining multiple candidate GAP starting positions corresponding to the frequency point to be detected based on the SMTC cycle index, the SMTC cycle, the minimum value of the GAP starting position, and the maximum value of the GAP starting position, the candidate GAP starting position index can be first determined based on the minimum value of the GAP starting position and the maximum value of the GAP starting position; and then, based on the SMTC cycle index, the SMTC cycle, the minimum value of the GAP starting position, and the candidate GAP starting position index, multiple candidate GAP starting positions can be jointly determined.

[0179] For example, when determining multiple candidate GAP starting positions based on the SMTC period index, SMTC period, GAP starting position minimum value and candidate GAP starting position index, multiple candidate GAP starting positions can be determined based on SmtcIndex*SmtcPeriod+(GapOffsetMin+GapOffsetIndex)mod SmtcPeriod, thereby calculating multiple candidate GAP starting positions.

[0180] Among them, SmtcIndex represents the SMTC period index, SmtcPeriod represents the SMTC period, GapOffsetMin represents the minimum value for determining the GAP starting position, and GapOffsetIndex represents the candidate GAP starting position index.

[0181] For example, when determining the SMTC cycle index, the difference between the candidate GAP cycle and the SMTC cycle may be determined first; then, based on the difference, the SMTC cycle index may be determined, thereby calculating and obtaining the SMTC cycle index.

[0182] For example, the value range of the SMTC period index is [0, GapOffsetMax–GapOffsetMin].

[0183] Combined with the above description, for multiple frequency points to be detected, multiple corresponding candidate GAP starting positions can be calculated, so that the target GAP starting position and target combination parameters can be further determined based on the multiple corresponding candidate GAP starting positions of the multiple frequency points to be detected, that is, the following S302-S304 are executed.

[0184] Among them, the target GAP starting position is the GAP starting position in the final configured GAP parameters, the GAP measurement duration in the target combination parameters is the GAP measurement duration in the final configured GAP parameters, and the GAP period in the target combination parameters is the GAP period in the final configured GAP parameters.

[0185] S302: Determine whether there is a same candidate GAP starting position among multiple candidate GAP starting positions corresponding to multiple frequency points to be detected.

[0186] It can be understood that in the embodiment of the present disclosure, after the frame header offset is introduced, it is theoretically possible that the configuration of the GAP parameters can cover all heterogeneous frequency points, or it is possible that the configuration of the GAP parameters cannot cover all heterogeneous frequency points. Specifically, this can be judged by determining whether there is the same candidate GAP starting position for multiple candidate GAP starting positions corresponding to multiple frequency points to be detected.

[0187] For example, in an embodiment of the present disclosure, when determining whether multiple candidate GAP starting positions corresponding to multiple frequency points to be detected have the same candidate GAP starting position, the multiple candidate GAP starting positions corresponding to the frequency points of the first priority among the multiple frequency points to be detected can be recorded as a first GapOffset set and saved as an available GapOffset set; the intersection of the available GapOffset set and the second GapOffset set corresponding to the frequency points of the second priority is taken to obtain a new available GapOffset set; the new available GapOffset set is then intersected with the third GapOffset set corresponding to the frequency points of the third priority to obtain a new available GapOffset set; and so on, the available GapOffset set is continuously updated until all the frequency points to be detected are traversed. If the available GapOffset set is empty, it means that the multiple candidate GAP starting positions corresponding to the multiple frequency points to be detected do not have the same candidate GAP starting position; if the available GapOffset set is not empty, it means that the multiple candidate GAP starting positions corresponding to the multiple frequency points to be detected have the same candidate GAP starting position.

[0188] It can be understood that when determining whether there are multiple candidate GAP starting positions corresponding to multiple frequency points to be detected, the above is just an example of taking the intersection in the order of priority to illustrate whether there are the same candidate GAP starting positions. It can also be determined in other orders, such as taking the intersection in the order of the identification of the points to be detected, to determine whether there are the same candidate GAP starting positions. The specific settings can be made according to actual needs.

[0189] For example, if the multiple candidate GAP starting positions corresponding to the multiple frequency points to be detected do not have the same candidate GAP starting position, it means that the configuration of the GAP parameters cannot cover all inter-frequency frequency points. In this case, in order to detect high-priority inter-frequency frequency points as much as possible, the embodiment of the present disclosure introduces an inter-frequency frequency point fallback mechanism. Specifically, when configuring the GAP parameters, high-priority frequency points are given priority, followed by low-priority frequency points. If it is not possible to cover all inter-frequency frequency points, the coverage of the low-priority frequency points can be abandoned and the coverage of the high-priority frequency points can be retained, that is, the following S303 is executed. If the multiple candidate GAP starting positions corresponding to the multiple frequency points to be detected do have the same candidate GAP starting position, it means that the configuration of the GAP parameters can cover all inter-frequency frequency points. In this case, the following S304 is executed.

[0190] S303. When it is determined that there is no identical candidate GAP starting position, remove the frequency point with the lowest priority from the multiple frequency points to be detected, and determine the updated frequency point as the new multiple frequency points to be detected. Repeat the above operation until the same candidate GAP starting position exists among the multiple candidate GAP starting positions corresponding to the new frequency points to be detected.

[0191] Assume that the multiple frequencies to be detected include frequency 1, frequency 2, frequency 3, frequency 4, and frequency 5. The multiple frequencies to be detected are sorted in descending order of priority, namely frequency 1, frequency 2, frequency 3, frequency 4, and frequency 5. That is, frequency 1 has the highest priority and frequency 5 has the lowest priority.

[0192] For example, if there is no identical candidate GAP starting position among the multiple candidate GAP starting positions corresponding to frequency point 1, frequency point 2, frequency point 3, frequency point 4 and frequency point 5, it means that the configuration of the GAP parameters cannot cover all inter-frequency frequency points. In this case, high-priority frequency points are given priority, followed by low-priority frequency points. Frequency point 5 with the lowest priority is removed from the multiple frequency points to be detected to obtain multiple new frequency points to be detected, including frequency point 1, frequency point 2, frequency point 3 and frequency point 4; and the new initial combination parameters are determined based on the inter-frequency SMTC starting positions of frequency point 1, frequency point 2, frequency point 3 and frequency point 4. , and based on the respective inter-frequency SMTC starting positions, GAP RF conversion timing and new initial combination parameters of frequency point 1, frequency point 2, frequency point 3 and frequency point 4, determine the multiple candidate GAP starting positions corresponding to each of frequency point 1, frequency point 2, frequency point 3 and frequency point 4; then determine whether the multiple candidate GAP starting positions corresponding to each of frequency point 1, frequency point 2, frequency point 3 and frequency point 4 have the same candidate GAP starting position, until the multiple candidate GAP starting positions corresponding to each of the new multiple frequency points to be detected have the same candidate GAP starting position, and the same candidate GAP starting position can cover all inter-frequency frequency points.

[0193] In the case of determining the same candidate GAP starting position, the specific implementation of determining the target GAP starting position and the target combination parameters can be found in the following S304.

[0194] S304: When there are identical candidate GAP starting positions, determine a target GAP starting position from the identical candidate GAP starting positions based on the number of terminals corresponding to the identical candidate GAP starting positions, and determine the initial combination parameters as the target combination parameters.

[0195] In combination with the description in the above S303, for example, if it is determined that multiple candidate GAP starting positions corresponding to frequency point 1, frequency point 2, frequency point 3 and frequency point 4 respectively have the same candidate GAP starting position, assuming that the same candidate GAP starting position includes candidate GAP starting position 1, candidate GAP starting position 2 and candidate GAP starting position 3, then according to the number of terminals served by candidate GAP starting position 1, candidate GAP starting position 2 and candidate GAP starting position 3 respectively, the candidate GAP starting position with the least number of terminals served can be determined from candidate GAP starting position 1, candidate GAP starting position 2 and candidate GAP starting position 3, and the candidate GAP starting position with the least number of terminals served is determined as the target GAP starting position. Correspondingly, the calculated initial combination parameters are determined as the target combination parameters, the GAP measurement duration in the target combination parameters is the target GAP measurement duration; and the GAP period in the target combination parameters is the target GAP period.

[0196] It can be seen that in the embodiment of the present disclosure, when determining the GAP parameters, the initial combination parameters can be first determined based on the respective inter-frequency SMTC starting positions of the multiple frequency points to be detected, and the multiple candidate GAP starting positions corresponding to the multiple frequency points to be detected can be determined based on the respective inter-frequency SMTC starting positions of the multiple frequency points to be detected, the GAP RF conversion timing and the initial combination parameters; and it can be determined whether the multiple candidate GAP starting positions corresponding to the multiple frequency points to be detected have the same candidate GAP starting position; and then the target GAP starting position, target GAP measurement duration and target GAP period are determined based on whether the same candidate GAP starting position exists, and the impact of the introduction of frame header offset on the GAP parameter configuration is fully considered. In this way, the impact of inconsistent frame header offsets of different frequency points on the configured GAP parameters can be avoided to a certain extent, so that the determined GAP parameters can cover all inter-frequency measurement time domain positions as much as possible, so that the terminal can accurately perform frequency detection based on the configured GAP parameters.

[0197] In order to facilitate understanding of the method for determining the gap GAP parameter provided by the embodiment of the present disclosure, the following two examples of GAP parameter configuration are listed for illustration.

[0198] Example 1

[0199] Assume that the frame header offset of inter-frequency point 1 is configured as 0, SmtcPeriod = 20ms, SmtcOffset = 0ms, and SmtcDuration = 2ms; the frame header offset of inter-frequency point 2 is configured as 3ms, SmtcPeriod = 20ms, SmtcOffset = 0ms, and SmtcDuration = 2ms; and the frame header offset of the current serving cell is configured as 0.

[0200] Using the method for determining the gap GAP parameters provided in the embodiment of the present disclosure, it is possible to calculate GapPattern = 0, GapMgrp = 40ms, GapMgl = 6ms, and GapMgta = 0.5ms. Correspondingly, a reference diagram of GapOffset can be seen in Figure 4, which is a schematic diagram of a GapOffset configuration provided by the embodiment of the present disclosure. The GapOffset configuration is 0ms, which can cover the measurement time domain positions of inter-frequency points 1 and 2, thereby enabling the terminal to accurately perform frequency point detection based on the configured GAP parameters.

[0201] Example 2

[0202] Example 2 includes two hetero-frequency points with different frame header offsets and corresponding SMTC configurations. The serving cell can choose to simultaneously measure the GAP parameter configurations of the two hetero-frequency points through the gap GAP parameter determination method provided by the embodiment of the present disclosure, that is, the determined GAP parameters can simultaneously cover the measurement time domain positions of the two hetero-frequency points.

[0203] Assume that the frame header offset of inter-frequency point 1 is configured as 0, SmtcPeriod = 20ms, SmtcOffset = 0ms, and SmtcDuration = 2ms; the frame header offset of inter-frequency point 2 is configured as 2.5ms, SmtcPeriod = 20ms, SmtcOffset = 0ms, and SmtcDuration = 2ms; and the frame header offset of the current serving cell is configured as 0.

[0204] By adopting the method for determining the gap GAP parameters provided by the embodiment of the present disclosure, it is possible to calculate GapPattern = 0, GapMgrp = 40ms, GapMgl = 6ms, and GapMgta = 0.5ms. Correspondingly, the reference diagram of GapOffset can be seen in Figure 5, which is a schematic diagram of another GapOffset configuration provided by the embodiment of the present disclosure. In Gap parameter configuration 1, GapOffset is configured to 49ms and GapMgta is configured to 0ms; in Gap parameter configuration 2, GapOffset is configured to 0ms and GapMgta is configured to 0.5ms. In this way, by flexibly configuring GapMgta, the optional position of GapOffset can be increased; and when GapOffset is configured to 49ms and GapOffset is configured to 0ms, the measurement time domain positions of the inter-frequency frequency point 1 and the inter-frequency frequency point 2 can be covered, so that the terminal can accurately perform frequency point detection based on the configured GAP parameters.

[0205] FIG6 is a schematic diagram of the structure of a network device provided by an embodiment of the present disclosure. As shown in FIG6 , the transmitting and receiving point includes a memory 620, a transceiver 600, and a processor 610, wherein:

[0206] The memory 620 is used to store computer programs; the transceiver 600 is used to send and receive data under the control of the processor 610; the processor 610 is used to read the computer program in the memory 620 and perform the following operations:

[0207] Determine respective inter-frequency SMTC starting positions of a plurality of frequency points to be detected, wherein at least two frequency points among the plurality of frequency points to be detected have different frame header offsets, and the inter-frequency SMTC starting positions are determined based on a global positioning system (GPS).

[0208] Based on the respective inter-frequency SMTC starting positions of the multiple frequency points to be detected, target combination parameters and target GAP starting positions are determined, where the target combination parameters include a target GAP measurement duration and a target GAP period.

[0209] The GAP parameters include the target GAP measurement duration, the target GAP period, and the target GAP starting position.

[0210] Specifically, the transceiver 600 is configured to receive and send data under the control of the processor 610 .

[0211] In FIG6 , the bus architecture may include any number of interconnected buses and bridges, specifically various circuits linked together by one or more processors represented by processor 610 and memory represented by memory 620.
