Description

Method and device for determining frequency position

Technical Field

The embodiment of the application relates to the technical field of communication, in particular to a method and equipment for determining a frequency position.

Background

Synchronization of current communication systems generally employs a primary synchronization signal and a secondary synchronization signal for signal synchronization. The time interval between the main synchronous signal and the auxiliary synchronous signal in the time domain is larger, and the synchronization time length required by the synchronization of the main synchronous signal and the auxiliary synchronous signal is increased. In order to reduce the synchronization time and save power consumption, a re-synchronization signal (RSS) is introduced. The resynchronization signal occupies 2 consecutive Resource Blocks (RBs) in the frequency domain and may be any two RBs within the system bandwidth, the lower RB of the two RBs being signaled to the terminal by the base station.

In the prior art, the terminal may further enhance the mobility performance of the user by measuring RSS of neighboring cells of the serving cell. However, in the prior art, the frequency domain location information of RSS needs 7 bits to indicate, and when there are many neighboring cells, the signaling overhead is large.

The first cell may be any one, and the first cell may be a serving cell or a neighboring cell of the serving cell. The first signal may be a re-synchronization signal RSS, or may be another signal, which is not limited in this application.

Accordingly, if the first cell is a serving cell, the frequency location of the first signal may be the frequency location of the RSS of the serving cell. If the first cell is a neighboring cell of the serving cell, the frequency location of the first signal may be a frequency location of an RSS of the neighboring cell of the serving cell.

Optionally, the first cell includes: a serving cell, and/or a neighbor 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 a neighboring cell of the serving cell. The first information for instructing the first device to determine a frequency location of the first signal includes: the first information is used for instructing the first equipment to determine the frequency position of the first signal of the serving cell and/or the first signals of the adjacent cells of the serving cell; also at least one of the following is indicated: indicating whether the frequency position of a first signal of a serving cell is the same as the frequency position of a first signal of an adjacent cell of the serving cell; and secondly, indicating whether the frequency set of the first signal of the serving cell is the same as the frequency set of the first signal of the adjacent cell of the serving cell, wherein the frequency set comprises a narrow band.

Optionally, the second device determines second information, where the second information is used to indicate: whether the frequency position of the first signal of the serving cell is the same as the frequency position 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 the same as the frequency set in which the first signal of the neighboring cell of the serving cell is located, wherein the frequency set comprises a narrow band.

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: 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 of the first signal of the serving cell is the same as or different from the frequency set of the first signal of the adjacent cell of the serving cell.

202. The second device sends the first information to the first device.

The first information may indicate a frequency set, and the first information may also indicate a corresponding frequency position in the frequency set. The first information may also indicate an offset and the first information may also indicate a frequency location. The frequency set includes at least one frequency unit, which may be a resource block or a narrowband.

Optionally, one set of frequencies may include: one or more resource blocks, or one or more narrow bands. Optionally, the frequency locations may include: resource block number or narrowband number.

One frequency set corresponds to one index, which may or may not be a number of the frequency set. For example, when a frequency set is a narrowband, and when a narrowband corresponds to a frequency set, the narrowband number may be used as an index of the frequency set, or the narrowband number may not be used as an index of the frequency set, for example, a corresponding relationship between the narrowband number and the index is established. One frequency set corresponds to one index, and the number corresponding to each resource block in the narrowband can be regarded as one frequency position.

When the first information indicates a frequency set, a corresponding frequency position in the frequency set, an offset, or a frequency position, the first information specific indication content thereof may be a value or a parameter, including N bits.

Specifically, the first information indicates a corresponding frequency position in the frequency set, taking the frequency set as a narrow band as an example, one narrow band generally includes 6 resource blocks, in this case, N may be 3, and the first information indicates each resource block in the narrow band using 3 bits, for example: 000 indicates the first resource block within the narrowband (numbered k1), 001 indicates the second resource block within the narrowband (numbered k2), 010 indicates the third resource block within the narrowband (numbered k3), 011 indicates the fourth resource block within the narrowband (numbered k4), 100 indicates the fifth resource block within the narrowband (numbered k5), 101 indicates the sixth resource block within the narrowband (numbered k6), wherein the order of the numbers k1-k6 may be from low bit to high bit or from high bit to low bit.

Specifically, the first information indicates a frequency set, for example, the frequency set is a narrow band, the system bandwidth includes L narrow bands, in this case, N may be ceil { log2(L) } bits, and the first information indicates the position of the narrow band in the system bandwidth by using N bits. The location of the narrowband may be determined by a narrowband index, and the first information indicates the narrowband index to determine the location of the narrowband. If the system bandwidth is 10MHz, 8 narrow bands are included, where N is 3, for example: 000 indicates a narrowband whose narrowband index is 0, 001 indicates a narrowband whose narrowband index is 1, 010 indicates a narrowband whose narrowband index is 2, 011 indicates a narrowband whose narrowband index is 3, 100 indicates a narrowband whose narrowband index is 4, 101 indicates a narrowband whose narrowband index is 5, 110 indicates a narrowband whose narrowband index is 6, and 111 indicates a narrowband whose narrowband index is 7.

In particular, the first information indicates an offset with an offset granularity of a first frequency unit, e.g., the first frequency unit is a resource block, a narrowband, or L resource blocks, L may be predefined or indicated by the second device. Illustratively, the first information indicates an offset of M, and then M first frequency units are offset. Alternatively, the offset may be in the direction of a large resource block number, or may be in the direction of a small resource block number.

Specifically, the first information indicates a frequency position, which may be a narrowband number, a resource block number, or a subcarrier number. The first information may directly indicate the frequency location, or the first indication information may indicate the frequency location according to a certain corresponding relationship.

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