Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to the technical field of communication, and in particular, to a frequency position determination method and device. BACKGROUND

[0002] Currently, the synchronization of a communication system usually uses a primary synchronization signal and a secondary synchronization signal to synchronize signals. The time interval between the primary synchronization signal and the secondary synchronization signal in the time domain is large, which increases the synchronization time length required for the primary synchronization signal and the secondary synchronization signal to synchronize. In order to reduce the synchronization time length and save power consumption, a resynchronization signal (RSS) is introduced. The resynchronization signal occupies two consecutive resource blocks (RBs) in the frequency domain, and can be any two RBs in the system bandwidth. The low-order RB of the two RBs is notified to the terminal by the base station through signaling.

[0003] In the prior art, the terminal can also measure the RSS of the neighboring cells of the serving cell, thereby further enhancing the mobile performance of the user. However, in the prior art, the frequency domain position information of the RSS needs to be indicated by 7 bits, and when there are many neighboring cells, the signaling overhead is large. SUMMARY

[0004] In order to solve the above technical problems, the present application provides a frequency position determination method for a terminal device to determine the frequency position of the RSS of each cell. The specific scheme is as follows:

[0006] In the present application, the first device determines the frequency position of the first signal based on the first information and the cell identifier. Since the cell identifier can narrow the frequency range corresponding to the frequency position of the first signal, the first information can determine the frequency position of the first signal within the smaller frequency range defined by the cell identifier. Generally speaking, the smaller the indicated frequency range, the smaller the signaling overhead. Therefore, by determining the frequency position of the first signal based on the first information and the cell identifier, the signaling overhead can be effectively reduced. In addition, since the cell identifier or the first information can limit the frequency position of the first signal corresponding to different cells within different candidate frequency ranges, the collision of the frequency positions of the first signals between the serving cell and the neighboring cells, and between multiple neighboring cells, can be reduced, thereby reducing the mutual interference between the serving cell and the neighboring cells, and between multiple neighboring cells, and improving the system performance.

[0077] In the prior art, the terminal can further enhance the mobility performance of the user by measuring the RSS of the neighboring cells of the serving cell. Currently, the frequency configuration information of each RSS needs to use 7-bit signaling to inform the terminal. When there are many neighboring cells, the signaling overhead is large.

[0078] In order to solve the problem of large signaling overhead required for indicating the frequency location of the RSS in the prior art, the embodiment of the present application provides a frequency location determination method. Please refer to Fig. 2(a), which is a schematic diagram of an interaction process between a first device and a second device according to the embodiment of the present application. The frequency location determination method according to the embodiment of the present application mainly includes the following steps:

[0079] 201. The second device determines first information, and the first information is used for indicating the first device to determine the frequency location of the first signal of the first cell.

[0080] The first cell can be any cell, which can be a serving cell or a neighboring cell of the serving cell. The first signal can be a re-synchronization signal (RSS) or other signals, which are not limited in the present application.

[0081] Correspondingly, if the first cell is the serving cell, the frequency location of the first signal can be the frequency location of the RSS of the serving cell. If the first cell is the neighboring cell of the serving cell, the frequency location of the first signal can be the frequency location of the RSS of the neighboring cell of the serving cell.

[0082] Optionally, the first cell includes the serving cell and / or the neighboring cell of the serving cell. The first signal of the first cell includes the first signal of the serving cell and / or the first signal of the neighboring cell of the serving cell. The first information used for indicating the first device to determine the frequency location of the first signal includes the first information used for indicating the first device to determine the frequency location of the first signal of the serving cell and / or the first signal of the neighboring cell of the serving cell, and further indicating at least one of the following: 1. indicating whether the frequency location of the first signal of the serving cell is same as the frequency location of the first signal of the neighboring cell of the serving cell; 2. indicating whether the frequency set in which the first signal of the serving cell is located is same as the frequency set in which the first signal of the neighboring cell of the serving cell is located, and the frequency set includes a narrow band.

[0083] Optionally, the second device determines second information, and the second information is used for indicating whether the frequency location of the first signal of the serving cell is same as the frequency location of the first signal of the neighboring cell of the serving cell, and / or whether the frequency set in which the first signal of the serving cell is located is same as the frequency set in which the first signal of the neighboring cell of the serving cell is located, and the frequency set includes a narrow band.

[0084] Further, the second device sends the second information to the first device, and the first device receives the second information and determines, according to the second information, that the frequency position of the first signal of the serving cell is the same as or different from the frequency position of the first signal of the neighboring cell of the serving cell; and / or, the frequency set in which the first signal of the serving cell is located is the same as or different from the frequency set in which the first signal of the neighboring cell of the serving cell is located.

[0085] 202. The second device sends the first information to the first device.

[0086] The first information can indicate a frequency set, and the first information can also indicate a corresponding frequency position in the frequency set. The first information can also indicate an offset, and the first information can also indicate a frequency position. The frequency set includes at least one frequency unit, and the frequency unit can be a resource block or a narrowband.

[0087] Optionally, a frequency set can include one or more resource blocks or one or more narrowbands. Optionally, a frequency position can include a resource block number or a narrowband number.

[0088] A frequency set corresponds to an index, which can be a number or not. For example, when a frequency set is a narrowband, and when a narrowband corresponds to a frequency set, the narrowband number can be used as the index of the frequency set, or the narrowband number can not be used as the index of the frequency set, for example, a corresponding relationship between the narrowband number and the index is established. A frequency set corresponds to an index, and the number corresponding to each resource block in the narrowband can be considered as a frequency position.

[0089] When the first information indicates a frequency set, a corresponding frequency position in the frequency set, an offset, or a frequency position, the specific indication content of the first information can be a value or a parameter, including N bits.

[0090] Specifically, the first information indicates a corresponding frequency position in the frequency set. Taking a narrowband as an example, a narrowband usually includes 6 resource blocks, at this time N can be 3, and the first information uses 3 bits to indicate each resource block in the narrowband, for example: 000 indicates the first resource block (numbered k1) in the narrowband, 001 indicates the second resource block (numbered k2) in the narrowband, 010 indicates the third resource block (numbered k3) in the narrowband, 011 indicates the fourth resource block (numbered k4) in the narrowband, 100 indicates the fifth resource block (numbered k5) in the narrowband, and 101 indicates the sixth resource block (numbered k6) in the narrowband. The order of the numbers k1-k6 can be from low bit to high bit, or from high bit to low bit.

[0091] Specifically, the first information indicates a frequency set. Taking a narrowband as an example of the frequency set, the system bandwidth includes L narrowbands, N can be ceil{log2(L)} bits, and the first information uses N bits to indicate the position of the narrowband in the system bandwidth. The position of the narrowband can be determined by a narrowband index, and the first information indicates the narrowband index to determine the position of the narrowband. For example, when the system bandwidth is 10 MHz and includes 8 narrowbands, N=3, 000 indicates the narrowband with the narrowband index 0, 001 indicates the narrowband with the narrowband index 1, 010 indicates the narrowband with the narrowband index 2, 011 indicates the narrowband with the narrowband index 3, 100 indicates the narrowband with the narrowband index 4, 101 indicates the narrowband with the narrowband index 5, 110 indicates the narrowband with the narrowband index 6, and 111 indicates the narrowband with the narrowband index 7.

[0092] Specifically, the first information indicates an offset, and the offset granularity is a first frequency unit. For example, the first frequency unit is a resource block, a narrowband, or L resource blocks, and L can be predefined or indicated by the second device. For example, the first information indicates an offset M, and the first signal is offset by M first frequency units. Optionally, the offset can be in the direction of a larger resource block number or in the direction of a smaller resource block number.

[0093] Specifically, the first information indicates a frequency position, which can be a narrowband number, a resource block number, or a subcarrier number. The first information can directly indicate the frequency position or indicate the frequency position according to a certain correspondence relationship.

[0094] It should be noted that, because the frequency position of the first signal is determined based on the first information and the cell identifier in the technical solution of the present application, the frequency range indicated by the first information can be reduced, and thus the signaling overhead can be saved.

[0095] 203. The first device determines the frequency position of the first signal according to the first information and the cell identifier.

[0096] The first device determines the frequency position of the first signal according to the first information and the cell identifier, which can be implemented in the following ways:

[0097] Firstly, the first device determines a first frequency set according to the cell identifier, the first frequency set including at least one frequency unit; and the first device determines the frequency position of the first signal in the first frequency set according to the first information.

[0098] For example, the first system bandwidth includes at least one frequency set, each frequency set including at least one frequency unit, and each frequency set corresponding to an index; the first device determines the first frequency set according to the cell identifier, and the following steps can be performed:

[0099] Step 11: The first device determines the first parameter according to the cell identifier.

[0100] The first parameter can be equal to the cell identifier. The first parameter can also be calculated from the cell identifier, and the specific calculation method includes but is not limited to one or more of the following: the cell identifier is divided by the first variable and rounded up, the cell identifier is divided by the second variable and rounded down, and the cell identifier is divided by the third variable and taken as a remainder.

[0101] Optionally, all of the first variable, the second variable, and the third variable can be constants, and the value of each variable is arbitrary; all of the first variable, the second variable, and the third variable can be configured by the first device; a part of the first variable, the second variable, and the third variable is configured by the first device, and another part of the first variable, the second variable, and the third variable is a constant, and the value of each variable in this part is arbitrary. It should be noted that this part of the description is applicable to the first variable, the second variable, and the third variable involved in the following description of the present application, and will not be repeated hereinafter.

[0102] Step 12: The first device determines the first index corresponding to the first parameter.

[0103] The first index can be equal to the first parameter. The first index and the first parameter have a corresponding relationship, the first index is determined by the first parameter and the corresponding relationship, and the corresponding relationship can include but is not limited to a corresponding relationship table or a corresponding relationship formula.

[0104] Step 13: The first device determines the first frequency set corresponding to the first index in the at least one frequency set.

[0105] The first index can be a narrowband number, for example, one narrowband corresponds to one frequency set.

[0106] For example, the first device determines the frequency position of the first signal in the first frequency set according to the first indication information, and can perform the following steps:

[0107] Step 14: The first device determines the second parameter according to the first information.

[0108] The second parameter can be directly indicated by the first information.

[0109] Step 15: The first device determines the frequency position corresponding to the second parameter in the first frequency set, and the frequency position corresponding to the second parameter in the first frequency set is the frequency position of the first signal.

[0110] The second way: The first device determines the second frequency set according to the first information, and the second frequency set includes at least one frequency unit; the first device determines the frequency position of the first signal in the second frequency set according to the cell identifier.

[0111] In particular, the second system bandwidth comprises at least one frequency set, each frequency set comprises at least one frequency unit, and each frequency set corresponds to an index;

[0112] For example, the first device determines the second frequency set according to the first information, and can perform the following steps:

[0113] Step 21: The first device determines the second index corresponding to the first information.

[0114] The second index can be directly indicated by the first information.

[0115] Step 22: The first device determines the second frequency set corresponding to the second index in the at least one frequency set.

[0116] For example, the first device determines the frequency position of the first signal in the second frequency set according to the cell identifier, and can perform the following steps:

[0117] Step 23: The first device determines the third parameter according to the cell identifier.

[0118] The third parameter can be equal to the cell identifier. The third parameter can also be calculated from the cell identifier, and the specific calculation method includes but is not limited to one or more of the following algorithms: the cell identifier is divided by the first variable and the upper integer is taken, the cell identifier is divided by the second variable and the lower integer is taken, and the cell identifier is calculated with respect to the third variable. Remainder.

[0119] Step 24: The first device determines the frequency position corresponding to the third parameter in the second frequency set, and the frequency position corresponding to the third parameter in the second frequency set is the frequency position of the first signal.

[0120] For example, the first device determines the second frequency set as N RBs (such as N=4, and the RB numbers are k1, k2, k3, and k4) according to the first information, and determines the position of the lowest RB of the first signal in the second frequency set according to the cell identifier (cell-ID), such as determining the position of the lowest RB of the first signal according to the following formula.

[0121] Wherein cell-ID, M, a are predefined constants or parameters configured by the network, x is configured by the base station through a higher layer or determined according to the first indication information or predefined, and f is the frequency position of the first signal.

[0122] Wherein, the cell-ID can be referred to as cell identity, and also can be referred to as physical layer cell identity. The first information indicates that the second frequency set is N RBs (such as N=4, and the RB numbers are k1, k2, k3, k4), and the number of the lowest RB of the first signal in the second frequency set is determined by the formula, such as x=N=4, M=1, a=0, when the cell-ID is 100, f=0, that is, the number of the lowest RB of the first signal k1 at this time.

[0123] It should be noted that the example corresponding to the first mode described above is the same as the example in the second mode described above, and the related description can refer to the description in the example described above, which will not be repeated here.

[0124] The third mode: the first device determines the first frequency position according to the cell-ID; the first device determines the first offset according to the first information; and the first device determines the frequency position of the first signal according to the first frequency position and the first offset.

[0125] In addition, the first device can also determine the first offset according to the first information; and the first device determines the frequency position of the first signal according to the first offset, the cell-ID, and the system bandwidth.

[0126] The first device can determine the first frequency position according to the cell-ID, which can perform the following steps:

[0127] Step 31: The first device determines the fourth parameter according to the cell-ID.

[0128] Similarly, the fourth parameter can be equal to the cell-ID. The fourth parameter can also be calculated from the cell-ID, and the specific calculation method includes but is not limited to one or more of the following: the cell-ID divided by the first variable and rounded up, the cell-ID divided by the second variable and rounded down, and the cell-ID modulo the third variable.

[0129] Step 32: The first device determines the third index corresponding to the fourth parameter.

[0130] Similarly, the third index can be equal to the fourth parameter. The third index and the fourth parameter have a corresponding relationship, and the third index is determined by the fourth parameter and the corresponding relationship, and the corresponding relationship can include but is not limited to a corresponding relationship table.

[0131] Step 33: The first device determines the frequency position corresponding to the third index, and the frequency position corresponding to the third index is the first frequency position.

[0132] Similarly, the third index can be equal to its corresponding frequency position, such as a resource block number. The frequency position (resource block number) corresponding to the third index can also be obtained by calculation from the third index. The specific calculation methods include but are not limited to one or more of the following algorithms: cell identity divided by the first variable and rounded up, cell identity divided by the second variable and rounded down, cell identity modulo the third variable.

[0133] For example, the first device determines the first offset according to the first information, and can perform the following steps:

[0134] Step 34: The first device determines the fifth parameter according to the first information.

[0135] The fifth parameter can be directly indicated by the first information.

[0136] Step 35: The first device determines the offset corresponding to the fifth parameter, and the offset corresponding to the fifth parameter is the first offset.

[0137] The fifth parameter can be equal to its corresponding offset. The offset corresponding to the fifth parameter can also be obtained by calculation from the fifth parameter. The specific calculation methods include but are not limited to one or more of the following algorithms: cell identity divided by the first variable and rounded up, cell identity divided by the second variable and rounded down, cell identity modulo the third variable. Step 36, determining the frequency position of the first signal according to the first offset and the first frequency position.

[0138] For example, the frequency position of the first signal is the position of the first frequency position offset by the first offset in the upward (high frequency direction, or large subcarrier number direction) direction, or the position of the first signal is the position of the first frequency position offset by the first offset in the downward (low frequency direction, or small subcarrier number direction) direction. It should be noted that the description of the first offset herein also applies to the second offset used in the fourth way.

[0139] For example, the first device can also determine the position of the first signal according to the first offset, the first frequency position and the system bandwidth. For example, the position of the first signal is calculated according to the following formula: (p+q)mod z, where p is the resource block number corresponding to the first frequency position, q is the first offset, and z is the number of resource blocks included in the system bandwidth. It should be noted that the description of the first offset herein also applies to the second offset used in the fourth way. Fourth way: the first device determines the second frequency position according to the first information; the first device determines the second offset according to the cell identity; the first device determines the frequency position of the first signal according to the second frequency position and the second offset.

[0140] For example, the first device determines the second frequency position according to the first information, and can perform the following operations:

[0141] Step 41: The first device determines a sixth parameter according to the first information.

[0142] The sixth parameter can be directly indicated by the first information.

[0143] Step 42: The first device determines a frequency position corresponding to the sixth parameter, and the frequency position corresponding to the sixth parameter is a second frequency position.

[0144] Similarly, the sixth parameter can be equal to the frequency position corresponding thereto, such as a resource block number. The frequency position corresponding to the sixth parameter (such as a resource block number) can also be obtained by calculation from the sixth parameter. The specific calculation methods include but are not limited to one or more of the following algorithms: cell identity divided by a first variable and then rounded up, cell identity divided by a second variable and then rounded down, cell identity relative to a third variable.

[0145] For example, the first device determines a second offset according to the cell identity, and the following steps can be performed:

[0146] Step 43: The first device determines a seventh parameter according to the cell identity.

[0147] Step 44: The first device determines a fourth index corresponding to the seventh parameter.

[0148] Step 45: The first device determines a fourth index corresponding to the offset, and the fourth index corresponding to the offset is a second offset.

[0149] For example, the first device determines an offset N according to the cell identity (or the first information), and N is an integer greater than or equal to 1. The first device determines a frequency position (resource block number) k1 according to the first information (or the cell identity), and the frequency position of the first signal is a resource block with a resource block number of (k1+N) or (k1+N) mod B, where B is the number of resource blocks contained in the system bandwidth, and mod is a remainder function.

[0150] The fifth way: The first device determines the frequency position of the first signal in a third frequency set according to the first information and the cell identity, and the third frequency set is predefined or configured by the second device.

[0151] For example, the first device determines the frequency position of the first signal according to the first information, the cell identity, and a first formula. The first formula can be:

[0152] The f is a frequency position or an index corresponding to a frequency set; The value of the cell identity, and a and / or M are determined according to the first information. The number of resource blocks or narrow bands in the third frequency set is less than or equal to x. Optionally, M and a can be indicated by first indication information and second indication information, respectively.

[0153] The sixth method: the first device determines the frequency granularity according to the first information, and determines the frequency position of the first signal at the frequency granularity according to the cell identifier; or the first device determines the frequency granularity according to the cell identifier, wherein the frequency granularity refers to the number of frequency units included between adjacent candidate positions of the first signal, and the frequency unit can be a resource block, a subcarrier or a narrowband. The candidate position of the first signal is a possible position of the first signal.

[0154] For example, the first device determines the frequency position of the first signal at the frequency granularity according to the cell identifier (or the first information).

[0155] For example, the first information (or the cell identifier) indicates that the frequency granularity is N, and the frequency position of the first signal at the frequency granularity is calculated according to the following formula.

[0156] The formula can be: Or Wherein f is the index corresponding to the frequency position or the frequency set, is the value of the cell identifier, M is predefined or configured by the second device, the second device can refer to the network, B is the number of resource blocks included in the system bandwidth, mod is the remainder function, N is the frequency granularity, and P is a predefined constant or configured by the second device.

[0157] The first system bandwidth and the second system bandwidth mentioned above refer to the working bandwidth of the communication system, and the working bandwidth of the first device is smaller than the working bandwidth of the communication system. The working bandwidth of the communication system can be the system bandwidth of the long term evolution (LTE) in particular. As shown in Table 1, it is a kind of corresponding relationship between the system bandwidth and the resource block (RB).

[0158] Table 1

[0159]

[0160] Optionally, the first device measures the intensity of the first signal at the frequency position of the first signal.

[0161] It should be noted that the formula mentioned in the present application is only an exemplary description, and any method with the same result as the formula is the protection content of the present application.

[0162] In order to further reduce the signaling overhead, another method for determining the frequency position is provided in the embodiments of the present application.

[0166] 205、The first device determines a frequency location of the first signal according to the cell identity of the first cell.

[0167] Correspondingly, if the first cell is a serving cell, the frequency location of the first signal can be a frequency location of an RSS of the serving cell. If the first cell is a neighboring cell of the serving cell, the frequency location of the first signal can be a frequency location of an RSS of the neighboring cell of the serving cell.

[0168] The system bandwidth includes a plurality of frequency sets, each frequency set includes at least one frequency unit, and each frequency set corresponds to an index. The first device determines the frequency location of the first signal according to the cell identity of the first cell, and the following steps can be performed:

[0169] Step 61: The first device determines an eighth parameter according to the cell identity.

[0170] Similarly, the eighth parameter can be equal to the cell identity. The eighth parameter can also be calculated from the cell identity, and the specific calculation method includes but is not limited to one or more algorithms of the ceiling function, the floor function, and the remainder function.

[0171] Step 62: The first device determines a fifth index corresponding to the eighth parameter.

[0172] Step 63: The first device determines a fourth frequency set corresponding to the fifth index.

[0173] Step 64: The first device determines a frequency location in the fourth frequency set, and the frequency location corresponding to the fourth frequency set is the frequency location of the first signal.

[0174] Optionally, the first device measures the strength of the first signal at the frequency location of the first signal.
