Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a method and device for determining a gap GAP parameter. Background Art

[0002] In the New Radio (NR) system, the terminal will periodically detect the frequency points of its serving cell and adjacent cells, and report the detection results to the network device, so that the network device determines the signal quality of the serving cell and the adjacent cell based on the detection results, and controls whether the terminal performs cell switching according to the signal quality of the serving cell and the adjacent cell.

[0003] Based on the existing NR protocol, before a terminal detects the frequencies of its serving cell and adjacent 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.

[0004] In the prior art, when a network device configures GAP parameters for a terminal, it does not consider the impact of inconsistent frame header offsets at different frequencies on the configured GAP parameters. This causes 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.

[0122] In the embodiments of the present application, the term "and / or" describes the association relationship of the associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0123] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0124] The technical solution provided in the embodiments of the present application can be applicable to a variety of systems, such as a 5G system.

[0125] Among them, the terminal involved in the embodiment of the present application may be a device that provides voice and / or data connectivity to a user, a handheld device with a wireless connection function, 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 a 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 may be a mobile terminal device, such as a mobile phone (or a "cellular" phone) and a computer with a mobile terminal device. For example, it may be a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device that exchanges language and / or data with a wireless access network. For example, personal communication service (PCS) phones, cordless phones, session initiation 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, and a user device, but is not limited in the embodiments of the present application.

[0126] The network device involved in the embodiment of the present application may be a base station, which may include multiple cells providing services for the terminal. Depending on the specific application scenario, the base station may also be called an access point, or may be a device in the access network that communicates with the wireless terminal device through one or more sectors on the air interface, or other names. The network device may be used to interchange received air frames with Internet Protocol (IP) packets, and serve 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 application may be a network device (Base Transceiver Station, BTS) in the Global System for Mobile communications (Global System for Mobile communications, GSM) or Code Division Multiple Access (Code Division Multiple Access, CDMA), or a network device (NodeB) in Wide-band Code Division Multiple Access (WCDMA), or an evolutionary network device (evolutional Node B, eNB or e-NodeB) in the long term evolution (long term evolution, LTE) system, a 5G base station (gNB) in the 5G network architecture (next generation system), or a home evolved Node B (Home evolved Node B, HeNB), a relay node, a home base station (femto), a pico base station (pico), etc., which is not limited in the embodiments of the present application. 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 arranged geographically separately.

[0127] For example, in an embodiment of the present application, one or more antennas may be used between the network device and the terminal device for multiple input multiple output (MIMO) transmission, and the MIMO transmission may be single user MIMO (SU-MIMO) or multi-user MIMO (MU-MIMO). Depending on the form and number of the antenna combination, the MIMO transmission may be 2D-MIMO, 3D-MIMO, FD-MIMO or massive-MIMO, or it may be diversity transmission, precoded transmission or beamforming transmission, etc.

[0128] In the New Radio (NR) system, the terminal will periodically detect the frequency points of its serving cell and adjacent cells, and report the detection results to the network device, so that the network device determines the signal quality of the serving cell and adjacent cells based on the detection results. If the signal quality of the reference signal of the adjacent cell is lower than the specified signal quality threshold, the terminal is instructed to continue to stay in the serving cell; on the contrary, if the signal quality of the reference signal of the adjacent cell is higher than the specified signal quality threshold, the terminal is instructed to switch from the serving cell to the adjacent cell to ensure that the terminal always stays in the cell with a better reference signal.

[0129] 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 RF conversion timing.

[0130] It is understandable that the GAP parameters may include other parameters in addition to the above four 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.

[0131] In the prior art, when the network device configures GAP parameters for the terminal, the impact of inconsistent frame header offsets of different frequencies on the configured GAP parameters is not considered, which 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.

[0132] 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.

[0133] In the presence of heterogeneous system frequencies, a GapPattern in which the GapMgl value is 6ms among the preset multiple GapPattern can be determined as multiple candidate GapPattern; then, based on the longest GapMgrp and the shortest GapMgl among the multiple candidate GapPattern, the final GapPattern is determined from the multiple candidate GapPattern, and the GapMgl and GapMgrp in the final GapPattern are the determined GapMgl and GapMgrp.

[0134] 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 value of GapMgl Ams among the preset multiple GapPatterns is determined as multiple candidate GapPattern, and then the final GapPattern is determined from the multiple candidate GapPattern based on the longest GapMgrp and the shortest GapMgl among the multiple candidate GapPattern. The GapMgl and GapMgrp in the final GapPattern are the determined GapMgl and GapMgrp.

[0135] 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+SmtcPeroid-GapOffsetIndex)%SmtcPeriod.

[0136] Among them, SmtcIndex indicates the SMTC period index in the GAP period, SmtcPeriod indicates the SMTC period, SmtcOffset indicates the SMTC starting position, GapOffsetIndex indicates that there is an available GapOffset position index in the SMTC measurement period, and SMTC is SSB Measurement Timing Configuration, SSB measurement timing configuration.

[0137] Among them, the range of SmtcIndex is [0, GapMgrp / SmtcPeriod-1], which indicates the SMTC period index within the GAP period. Usually, the GAP period is greater than the SMTC period and they are multiples. The range of GapOffsetIndex is [0, GapMgl–SmtcDuration–2*GapMgta], which indicates that there are available GapOffset position indexes within an SMTC measurement period.

[0138] 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 0.5 ms.

[0139] Combined with the above description, the GAP parameters including GapMgl, GapMgrp, GapOffset, and GapMgta can be determined. If there are multiple GapOffsets, it is necessary to consider the discrete configuration of GAP between cell users and try to stagger the scheduling timing of different users, including: giving priority to the discreteness between SMTC cycles; secondly, the discreteness within the SMTC cycle; within the SMTC discrete interval, select the GapOffset with fewer users as the final GapOffset to determine the GAP parameters.

[0140] For ease of understanding, an example of existing GAP parameter configuration is given. In this example, assuming that inter-frequency point 1: frame header offset is configured as 0, SmtcPeriod = 20ms, SmtcOffset = 0ms, SmtcDuration = 2ms; inter-frequency point 2: frame header offset is configured as 3ms, SmtcPeriod = 20ms, SmtcOffset = 0ms, SmtcDuration = 2ms, then the existing GAP parameter configuration method is used, and the impact of inconsistent frame header offsets between inter-frequency points 1 and 2 on the configuration of GAP parameters is not considered. The calculated GapOffset can be found in Figure 1 As shown, Figure 1 A schematic diagram of a GapOffset configuration provided for the prior art, in which the GapOffset is configured as 47ms, 48ms, 49ms, and 0ms. At any of the GapOffset positions, only the measurement of the heterofrequency frequency point 1 can be achieved, while the measurement of the heterofrequency 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.

[0141] 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 an embodiment of the present application, 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.

[0142] It can be seen that by determining the GPS-based heterofrequency SMTC starting position of each frequency point and determining the GAP parameters based on the GPS-based heterofrequency 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 all heterofrequency measurement time domain positions as much as possible, so that the terminal can accurately perform frequency detection based on the configured GAP parameters.

[0143] Below, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0144] Figure 2 The present invention provides a flow chart of a method for determining a gap GAP parameter according to an embodiment of the present invention. The method for determining a gap GAP parameter can be applied to a network device. For example, see Figure 2 As shown, the method for determining the gap GAP parameter may include:

[0145] 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.

[0146] In the embodiment of the present application, precisely because of the impact of inconsistent frame header offsets of different frequency points on the configuration of GAP parameters, when configuring the 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.

[0147] After determining the respective inter-frequency SMTC starting positions of the multiple frequency points to be detected, the following S202 may be executed:

[0148] S202. Determine target combination parameters and target GAP starting position based on respective hetero-frequency SMTC starting positions of multiple frequency points to be detected. The target combination parameters include target GAP measurement duration and target GAP period. Among them, GAP parameters include target GAP measurement duration, target GAP period and target GAP starting position.

[0149] For example, in the embodiment of the present application, 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 conversion timing, which can be specifically set according to actual needs.

[0150] It should be noted that in the embodiment of the present application, 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.

[0151] It can be seen that in the embodiment of the present application, when determining the GAP parameters, the inter-frequency SMTC starting positions of each of the multiple frequency points to be detected can be determined first, and there are at least two frequency points among the multiple frequency points to be detected with different frame header offsets, and the inter-frequency SMTC starting positions are determined based on GPS; then, based on the inter-frequency SMTC starting positions 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, the GAP parameters are determined based on the inter-frequency SMTC starting positions of each of the multiple frequency points to be detected, which can avoid the influence of inconsistent frame header offsets of different frequency points on the configuration of GAP parameters 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.

[0152] Based on the above Figure 2 In order to facilitate understanding of the embodiment of the present application, how to determine the target combination parameter and the target GAP starting position based on the respective inter-frequency SMTC starting positions of multiple frequency points to be detected, the following will be described. Figure 3 The illustrated embodiments are described in detail.

[0153] Figure 3The present invention provides a flow chart of determining a target combination parameter and a target GAP starting position, which can be applied to a network device. For example, see Figure 2 As shown, the method may include:

[0154] S301. Determine initial combination parameters based on the respective inter-frequency SMTC starting positions of the multiple frequency points to be detected, and determine 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 an initial GAP measurement duration and an initial GAP period.

[0155] For example, in an embodiment of the present application, 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:

[0156] In a possible scenario, there are heterogeneous system frequencies among multiple frequencies to be detected. When determining the initial combination parameters, the combination parameter with the value of GapMgl of 6ms in the preset multiple combination parameters GapPattern is determined as multiple candidate combination parameters; each candidate combination parameter includes a candidate GAP measurement duration and a candidate GAP period; and then based on the longest GAP period included in the multiple candidate combination parameters, the target combination parameter is determined from the multiple candidate combination parameters.

[0157] For example, in the embodiment of the present application, the preset multiple combination parameters can be seen in the following Table 1:

[0158] Table 1

[0159]

[0160]

[0161] 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 in which GapMgl takes the value of 6ms is determined as multiple candidate combination parameters, and the multiple candidate combination parameters are combination parameters whose combination parameter identifiers are 0, 1, 4 and 5.

[0162] In another possible scenario, there are hetero-frequency points among the multiple frequency points to be detected. When determining the initial combination parameters, multiple candidate combination parameters can be determined based on the hetero-frequency SMTC starting positions of the multiple frequency points 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; and 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.

[0163] The GAP parameters also include GAP radio frequency switching timing.

[0164] For example, in this possible scenario, when determining multiple candidate combination parameters based on the respective hetero-frequency SMTC starting positions of multiple frequency points to be detected and the preset GAP RF conversion timing, the value of GapMgl can be determined based on GapMgl>=(SmtcDuration+2*GapMgta), and multiple candidate combination parameters can be determined from the preset multiple combination parameters GapPattern based on the value of GapMgl. Among them, the preset multiple combination parameters can be seen in Table 1, which will not be repeated here.

[0165] In combination with any of the above possible scenarios, when determining the target combination parameters 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.

[0166] 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.

[0167] 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. Among them, the GAP measurement duration in combination parameter 0 is 6, and the GAP cycle is 40; the GAP measurement duration in combination parameter 1 is 6, and the GAP cycle is 80; the GAP measurement duration in combination parameter 4 is 6, and the GAP cycle is 20; and the GAP measurement duration in combination parameter 5 is 6, and the GAP cycle is 160. Among them, the longest GAP cycle is 160, and the candidate combination parameter including the longest GAP cycle 160 is combination parameter 5, so combination parameter 5 can be directly determined as the initial combination parameter.

[0168] For another example, 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. Among them, the GAP measurement duration in combination parameter 0 is 6, and the GAP cycle is 40; the GAP measurement duration in combination parameter 1 is 6, and the GAP cycle is 80; the GAP measurement duration in combination parameter 3 is 3, and the GAP cycle is 80; the GAP measurement duration in combination parameter 4 is 6, and the GAP cycle is 20. Among them, the longest GAP cycle is 80, and the candidate combination parameters including the longest GAP cycle 80 are combination parameter 1 and combination parameter 3; in this case, the shortest GAP measurement duration of combination parameter 1 and combination parameter 3 is further determined, and the shortest GAP measurement duration is 3, and combination parameter 1 including the shortest GAP measurement duration 3 is determined as the initial combination parameter.

[0169] 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.

[0170] For example, in an embodiment of the present application, 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, when determining the multiple candidate GAP starting positions corresponding to the multiple frequency points to be detected, the configuration granularity of the GAP measurement can be appropriately relaxed. The prior art can only configure the GAP measurement interval with an accuracy of 1ms. In an embodiment of the present application, by flexibly configuring the GAP RF 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:

[0171] 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.

[0172] 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.

[0173] By way of example, in an embodiment of the present application, when determining the minimum value of the GAP starting position based on the hetero-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.

[0174] Among them, GapOffsetMin represents the minimum value of the GAP starting position, AbsSmtcOffset represents the starting position of the heterofrequency 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.

[0175] By way of example, in an embodiment of the present application, when determining the maximum value of the GAP starting position based on the heterofrequency SMTC starting position of the frequency to be detected, the GAP RF conversion duration 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.

[0176] 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 time, GapMgta indicates the GAP radio frequency switching time, and GapMgrp indicates the initial GAP period. For example, the GAP radio frequency switching time can be set to 0.5ms, which can be set according to actual needs.

[0177] By way of example, in an embodiment of the present application, 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 GAP starting position value, and the maximum GAP starting position value, the candidate GAP starting position index can be first determined based on the minimum GAP starting position value and the maximum GAP starting position value; and then, based on the SMTC cycle index, the SMTC cycle, the minimum GAP starting position value, and the candidate GAP starting position index, multiple candidate GAP starting positions can be jointly determined.

[0178] 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.

[0179] Among them, SmtcIndex represents the SMTC period index, SmtcPeriod represents the SMTC period, GapOffsetMin represents the minimum value of the GAP starting position, and GapOffsetIndex represents the candidate GAP starting position index.

[0180] 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.

[0181] For example, the value range of the SMTC period index is [0, GapOffsetMax–GapOffsetMin].

[0182] 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 candidate GAP starting positions corresponding to the multiple frequency points to be detected, that is, the following S302-S304 are executed.

[0183] Among them, the target GAP starting position is the GAP starting position in the finally configured GAP parameters, the GAP measurement duration in the target combination parameters is the GAP measurement duration in the finally configured GAP parameters, and the GAP period in the target combination parameters is the GAP period in the finally configured GAP parameters.

[0184] 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.

[0185] It can be understood that in the embodiment of the present application, after the frame header offset is introduced, it is theoretically possible that the configuration of the GAP parameters can cover all heterofrequency points, or it is possible that the configuration of the GAP parameters cannot cover all heterofrequency points. Specifically, it can be judged by determining whether there are the same candidate GAP starting positions for multiple candidate GAP starting positions corresponding to multiple frequency points to be detected.

[0186] By way of example, in an embodiment of the present application, 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 the first GapOffset set and saved as the 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 multiple 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.

[0187] It can be understood that when determining whether there are the same candidate GAP starting positions among the multiple candidate GAP starting positions corresponding to the multiple frequency points to be detected, the above is only explained by taking the intersection in the order of priority. 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 setting can be made according to actual needs.

[0188] For example, when there is no identical candidate GAP starting position among multiple candidate GAP starting positions corresponding to multiple frequency points to be detected, it means that the configuration of 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 application introduces an inter-frequency frequency point fallback mechanism. Specifically, when configuring GAP parameters, high-priority frequency points are given priority, followed by low-priority frequency points. If all inter-frequency frequency points cannot be covered, the coverage of low-priority frequency points can be abandoned, and the coverage of high-priority frequency points is retained, that is, the following S303 is executed. When there is an identical candidate GAP starting position among multiple candidate GAP starting positions corresponding to multiple frequency points to be detected, it means that the configuration of GAP parameters can cover all inter-frequency frequency points. In this case, the following S304 is executed.

[0189] 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, and 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.

[0190] Assuming 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.

[0191] 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 heterofrequency 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 heterofrequency 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 of frequency point 1, frequency point 2, frequency point 3 and frequency point 4, the GAP RF conversion timing and the new initial combination parameters, 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 frequencies to be detected have the same candidate GAP starting position, and the same candidate GAP starting position can cover all inter-frequency frequency points.

[0192] In the case of determining the same candidate GAP start position, the specific implementation of determining the target GAP start position and the target combination parameter may refer to the following S304.

[0193] 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.

[0194] In combination with the description in S303 above, for example, if it is determined that there is an identical candidate GAP starting position among multiple candidate GAP starting positions corresponding to frequency 1, frequency 2, frequency 3 and frequency 4, assuming that the identical 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 served terminals 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 served terminals is determined as the target GAP starting position, and 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.

[0195] It can be seen that in the embodiment of the present application, when determining the GAP parameters, the initial combination parameters can be first determined based on the respective hetero-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 hetero-frequency SMTC starting positions of the multiple frequency points to be detected, the GAP RF conversion timing and the initial combination parameters; and it is 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, so that the impact of inconsistent frame header offsets of different frequencies on the configured GAP parameters can be avoided to a certain extent, so that the determined GAP parameters can cover all hetero-frequency measurement time domain positions as much as possible, so that the terminal can accurately perform frequency detection based on the configured GAP parameters.

[0196] In order to facilitate understanding of the method for determining the gap GAP parameter provided in the embodiment of the present application, the following two examples of GAP parameter configuration are listed for illustration.

[0197] Example 1

[0198] Assume that the inter-frequency point 1: the frame header offset is configured to 0, SmtcPeriod = 20ms, SmtcOffset = 0ms, SmtcDuration = 2ms; the inter-frequency point 2: the frame header offset is configured to 3ms, SmtcPeriod = 20ms, SmtcOffset = 0ms, SmtcDuration = 2ms; the frame header offset of the current serving cell is configured to 0.

[0199] By using the method for determining the gap GAP parameters provided in the embodiment of the present application, it is possible to calculate GapPattern = 0, GapMgrp = 40ms, GapMgl = 6ms, and GapMgta = 0.5ms. Correspondingly, the reference diagram of GapOffset can be found in Figure 4 As shown, Figure 4 A schematic diagram of a GapOffset configuration provided for the implementation of the present application, where the GapOffset is configured to 0ms, can cover the measurement time domain positions of inter-frequency frequency point 1 and inter-frequency frequency point 2, so that the terminal can accurately perform frequency point detection based on the configured GAP parameters.

[0200] Example 2

[0201] Example 2 includes two hetero-frequency points with different frame header offsets and corresponding SMTC configurations. The service cell can choose to simultaneously measure the GAP parameter configuration of the two hetero-frequency points through the method for determining the gap GAP parameters provided in the embodiment of the present application, that is, the determined GAP parameters can simultaneously cover the measurement time domain positions of the two hetero-frequency points.

[0202] Assume that the inter-frequency point 1: the frame header offset is configured to 0, SmtcPeriod = 20ms, SmtcOffset = 0ms, SmtcDuration = 2ms; the inter-frequency point 2: the frame header offset is configured to 2.5ms, SmtcPeriod = 20ms, SmtcOffset = 0ms, SmtcDuration = 2ms; the frame header offset of the current serving cell is configured to 0.

[0203] By using the method for determining the gap GAP parameters provided in the embodiment of the present application, it is possible to calculate GapPattern = 0, GapMgrp = 40ms, GapMgl = 6ms, and GapMgta = 0.5ms. Correspondingly, the reference diagram of GapOffset can be found in Figure 5 As shown, Figure 5 A schematic diagram of another GapOffset configuration provided for the implementation of the present application, 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 hetero-frequency frequency points 1 and 2 can be covered, so that the terminal can accurately perform frequency detection based on the configured GAP parameters.

[0204] Figure 6A schematic diagram of the structure of a network device provided in an embodiment of the present application is shown in FIG. Figure 6 As shown, the transmitting and receiving point includes a memory 620, a transceiver 600, and a processor 610, wherein:

[0205] 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:

[0206] Determine the inter-frequency SMTC starting positions 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 positions are determined based on a global positioning system GPS.

[0207] Based on the respective inter-frequency SMTC starting positions of the multiple frequency points to be detected, a target combination parameter and a target GAP starting position are determined, wherein the target combination parameter includes a target GAP measurement duration and a target GAP period.

[0208] The GAP parameters include the target GAP measurement duration, the target GAP period, and the target GAP starting position.

[0209] Specifically, the transceiver 600 is used to receive and send data under the control of the processor 610 .

[0210] Among them, Figure 6 In the embodiment, the bus architecture may include any number of interconnected buses and bridges, specifically linking together various circuits of one or more processors represented by processor 610 and memory represented by memory 620.
