detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is an embodiment of the invention, but not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of the present invention.

The terms "first", "second", "third", "fourth", etc. (if present) in the specification and claims of the present invention and the above figures are used to distinguish similar objects without being used for Describe a specific order or order. It is to be understood that the data so used may be interchanged where appropriate so that the embodiments described herein can be implemented in a sequence other than what is illustrated or described herein. In addition, the terms "comprises" and "comprises" and "the" and "the" are intended to cover a non-exclusive inclusion, for example, a process, method, system, product, or device that comprises a series of steps or units is not necessarily limited to Those steps or units may include other steps or units not explicitly listed or inherent to such processes, methods, products or devices.

In order to facilitate the understanding of the embodiments of the present invention, the principle of reporting the band combination in the present invention is described below:

The present invention solves the problem of reporting a large amount of redundant data in the process of reporting a plurality of frequency band combinations in the prior art, and proposes a reporting mode of a band combination with an extended threshold to solve the problem of reporting a large amount of redundant data in the prior art. By newly adding an extended threshold cell in the band combination, for example, the cell of the extended threshold may be “Expand Threshold”, the value of the extended threshold is smaller than the data of the band parameter cell in the band combination, and the band parameter cell The identification of the frequency band in the frequency band combination (English full name: Identity, English abbreviation: ID) is indicated, and the frequency band combination includes one or more frequency band parameter cells. After receiving the frequency band combination of the cell with the extended threshold, the base station may perform the subset decomposition by using the extended threshold, and the decomposed subset is the frequency band combination supported by the UE. The decomposition mode of the subset decomposition by the extended threshold is: If the data of the band parameter cell in the band combination is m and the value of the spreading threshold is n, the band combination is decomposed into a band combination containing X band parameter cells by an extended threshold, where n≤X<m, And n is a positive integer and X is a natural number. Obviously, the present invention can realize one or more frequency band combinations and one or more frequency band combination decompositions by selecting one or more frequency band combinations from the frequency band combinations to be reported and decomposing by selecting one or more frequency band combinations. The subset of the frequency band is composed of the frequency band combination to be reported. It can be seen that, in the case that the frequency band combination data to be reported is large, the number of frequency band combinations reported by the present invention will be much smaller than the frequency band combination reported in the prior art. It is natural that the present invention can reduce the reporting of redundant data.

Based on the above principles, the present invention will be described by way of the following examples:

Referring to FIG. 1, an embodiment of a method for reporting a frequency band combination in an embodiment of the present invention includes:

The base station receives the frequency band combination reported by the user equipment UE, where the frequency band combination carries an extended threshold, and the extended threshold is less than or equal to the number of frequency band parameter cells in the frequency band combination;

In this embodiment, after the UE reports the frequency band combination to the base station, and the frequency band combination carries an extended threshold, the base station receives the extended threshold and the frequency band combination.

The extended threshold is a positive integer, and the extended threshold is less than or equal to the number of frequency band parameter cells in the frequency band combination.

It should be noted that the above band combination includes one or more band parameter cells, and the band parameter cell indicates the ID of the band in the band combination and the support capability of the band.

Optionally, in some embodiments of the present invention, the foregoing frequency band combination is located in the set, specifically:

It should be noted that if the frequency band is combined into the first frequency band combination, the set may further include other frequency band combinations, such as a second frequency band combination and a third frequency band combination.

Optionally, in some embodiments of the present invention, after receiving the frequency band combination, the method further includes: if the extended threshold is smaller than the number of frequency band parameter cells in the frequency band combination, the base station decomposes the frequency band combination by using the extended threshold Get multiple extended band combinations.

It should be noted that, in some embodiments of the present invention, a specific decomposition manner of a plurality of extended frequency band combinations is obtained by decomposing the frequency band combination by the base station through the extended threshold, as follows:

If the number of the band parameter cells in the band combination is m, and the value of the spreading threshold is n, the base station decomposes the band combination into a plurality of extended band combinations containing X band parameter cells by using the extended threshold. Where n≤X<m.

Suppose the band combination is {1, A+B+C}, obviously m is 3, n is 1, then X is 1 and 2, and {1, A+B+C} is decomposed to get {A}, {B} , {C}, {A+B}, {A+C}, and {B+C}.

In addition, since the same band parameter cell may exist in the band combination, when the same band parameter cell exists, a repeated extended band combination occurs in the plurality of extended band combinations obtained by the decomposition, and therefore, some of the present invention In an embodiment, the method further includes:

The repeated extended band combinations in the plurality of extended band combinations described above are removed.

For example, the band combination is {3, A+B+B+D}, and the decomposition yields: {A+B+B}, {A+B+D}, and {B+B+D}.

102. The base station determines, by using the extended threshold, that the frequency band combination supported by the UE includes: the frequency band combination and a plurality of extended frequency band combinations, where the multiple extended frequency bands are combined into a subset of the frequency band combination.

Obviously, the band combination and the plurality of extended bands are combined into a part supported by the UE or a combination of all bands.

It should be noted that if the spreading threshold is equal to the number of band parameter cells in the band combination, the base station does not need to decompose the band combination by the extended threshold.

Optionally, in some embodiments of the present invention, the method further includes:

The target band parameter cell in the plurality of extended band combinations has information of the target band parameter cell in the band combination, the information including an identification ID of a target band indicated by the target band parameter cell, and in the band combination The support capability of the target frequency band, wherein the target frequency band parameter cell is any one of the plurality of extended frequency band combinations.

If the frequency band combination and the plurality of extended frequency bands are combined into a frequency band combination of the part supported by the UE, in order to obtain all the frequency band combinations supported by the UE, it is obvious that one or more frequency band combinations carrying the extended threshold are required, and the UE is combined to form a UE. All of the supported frequency band combinations, and thus, in some embodiments of the present invention, if the frequency band combination is a first frequency band combination, the plurality of extended frequency bands are combined into a plurality of first extended frequency band combinations, and the set further includes a second a combination of the second frequency band carrying the target extension threshold, the base station decomposing the second frequency band combination by the target expansion threshold, to obtain a plurality of second extended frequency band combinations, where the plurality of second extended frequency bands are combined a subset of the two-band combination; the base station determining that the frequency band combination supported by the UE comprises: the second frequency band combination and the plurality of second extended frequency band combinations.

It can be understood that, by using the foregoing method, the base station can acquire all frequency band combinations supported by the UE.

It should be noted that, in practical applications, the same plurality of frequency band combinations may exist in the plurality of first extended frequency band combinations and the plurality of second extended frequency band combinations, and thus, in some embodiments of the present invention, The case of the same band combination is handled as follows:

And if the plurality of first extension band combinations and the plurality of second extension bands are combined to have the same extended band combination Y, the extended band combination Y is used from the plurality of second extended band combinations. And removing, wherein the first frequency band combination is decomposed before the second frequency band combination.

For example, the above set is {{1, A+B}, {1, A+C}}, and {1, A+B} is decomposed to get {A} and {B}; for {1, A+C} decomposition Get {A} and {C}, where A in {1, A+C} is repeated, discarding the resulting {A}, leaving {C}.

In this embodiment, the present invention does not report the extended frequency band combination in the process of reporting, and the base station can obtain the extended frequency band combination by extending the threshold, and the base station obtains the extended frequency band combination by reporting the extended frequency band combination by the UE in the prior art. For the same purpose, and with respect to the prior art, the present invention eliminates the process of reporting the extended band combination. In the case of a large number of extended band combinations, the prior art reports a large amount of redundant data in the process of reporting the extended band combination. Therefore, the present invention can reduce the reporting of redundant data.

The method for reporting the reported frequency band combination of the present invention is described above from the base station side, and the method for reporting the band combination of the present invention is described below from the UE side:

Referring to FIG. 2, an embodiment of a method for reporting a frequency band combination in an embodiment of the present invention includes:

201. The user equipment UE generates a frequency band combination.

In this embodiment, after the user equipment UE determines a plurality of frequency band combinations to be reported, the UE generates a frequency band combination.

Optionally, in some embodiments of the present invention, the UE may generate a frequency band combination by:

Selecting a frequency band combination from a plurality of frequency band combinations to be reported, so that the plurality of frequency bands obtained by decomposing the selected frequency band combination by the decomposition method of the extended threshold are combined into frequency band combinations in the plurality of frequency band combinations to be reported;

Combining the selected frequency bands as a band combination;

The decomposition of the above extended thresholds includes:

If the number of the frequency band parameter cells in the selected frequency band combination is m, and the value of the extended threshold is n, the selected frequency band combination is decomposed into multiple extensions including X frequency band parameter cells by using the extended threshold. Band combination, where n ≤ X < m.

Obviously, the other frequency band combinations can be selected from the plurality of frequency band combinations to be reported, so that the decomposed frequency band combination and the selected frequency band combination form a plurality of frequency band combinations to be reported, so that the base station can acquire all the multiple to be reported. Band combination.

202. The UE reports the frequency band combination to the base station, where the frequency band combination carries an extended threshold, and the extension The threshold is less than or equal to the number of the frequency band parameter cells in the frequency band combination, so that after receiving the frequency band combination, the base station determines, by using the extended threshold, that the frequency band combination supported by the UE includes: the frequency band combination and the multiple extended frequency band combinations, Multiple extended frequency bands are combined into a subset of the frequency band combinations.

After the UE generates the frequency band combination, the UE reports the frequency band combination to the base station, where the frequency band combination carries an extended threshold, the extended threshold is a positive integer, and the extended threshold is less than or equal to the number of the frequency band parameter cells in the frequency band combination, The frequency band combination and the plurality of extended frequency bands obtained by the above-described extended threshold decomposition are combined into a frequency band combination supported by the UE, and the plurality of extended frequency bands are combined as a subset of the frequency band combination.

Obviously, after receiving the frequency band combination, the base station decomposes the frequency band combination by using an extended threshold to obtain the plurality of extended frequency band combinations, and determines that the frequency band combination supported by the UE comprises: the frequency band combination and the plurality of extended frequency band combinations.

Optionally, in some embodiments of the present invention, the base station acquires all frequency band combinations supported by the UE by reporting the frequency band combination, specifically:

If the UE supports all the frequency band combinations of the different frequency bands respectively indicated by the plurality of frequency band parameter cells, and the support capability of the frequency bands in all the frequency band combinations remains unchanged, the UE reports the frequency band combination to the base station, and the frequency band is used. The combination carries an extended threshold, and the value of the extended threshold is 1.

For example, if the UE supports all frequency band combinations of different frequency bands respectively indicated by the n frequency band parameter cells, the support capabilities of the different frequency bands indicated by the n frequency band parameter cells in all the above frequency band combinations are supported. In the prior art, the reporting method needs to report 2 ⁿ -1 frequency band combinations. According to the present invention, only one frequency band combination needs to be reported. It is assumed that the UE supports all frequency band combinations of four frequency bands a, b, c, and d. Corresponding to the four frequency band parameter cells of A, B, C, and D respectively, the number of frequency band combinations required by the prior art reporting method is 15, and only one method needs to be reported in the manner of using the frequency band combining extension threshold of the present invention. That is, report {1, A+B+C+D}.

It can be understood that the support capability of the frequency band indicated by the band parameter cell in the above example remains unchanged in all frequency band combinations. In practical applications, the frequency band indicated by the band parameter cell supports the support in different frequency band combinations. Possible changes, for example, the UE also supports all frequency band combinations of the four frequency bands a, b, c, and d, and also corresponds to four frequency band parameter cells A, B, C, and D, respectively, but c and d are supported by the capability. The corresponding band parameter cells are C1 and D1 at 1CC or 2CC, and the corresponding band parameter cells are C2 and D2 at 3CC or 4CC, which is required by the prior art reporting method. The number of required frequency band combinations is 15. The method of using the band combination with the extended threshold of the present invention only needs to report seven, as follows:

{{3,A+B+C2+D2},{1,A+B},{2,A+C1},{2,A+D1},{2,B+C1},{2,B+ D1}, {1, C1+D1}}

It should be noted that the above 1CC, 2CC, 3CC, and 4CC refer to a band combination of one band parameter cell, a band combination of two band parameter cells, a band combination of three band parameter cells, and four bands, respectively. The frequency band combination of the parameter cells.

In this embodiment, the present invention does not report the extended frequency band combination in the process of reporting, and the base station can obtain the extended frequency band combination by extending the threshold, so that the base station reports the extended frequency band combination through the UE in the prior art, and obtains the extended frequency band combination. For the same purpose, and with respect to the prior art, the present invention omits the process of reporting the extended band combination. In the case of a large number of extended band combinations, the prior art reports a large amount of redundant data in the process of reporting the extended band combination. Therefore, the present invention can reduce the reporting of redundant data.

For ease of understanding, a method for reporting a band combination according to an embodiment of the present invention is described below in an actual application scenario:

Assume that the set supported by the UE is {{A+B+C}, {A+B}, {A+C}, {A}, {B}, {C}}, and the unsupported band combination is {B+C }, in order to ensure that the reported frequency band combination and the frequency band subset obtained by the frequency band combination decomposition are the frequency band combinations supported by the UE, the UE is from the set {{A+B+C}, {A+B}, {A+C}, { A}, {B}, {C}} select {A+B+C}, {A+B}, and {A+C}, and configure the extended threshold 3 for {A+B+C}, which is {A +B}Configure the extended threshold 1, configure the extended threshold 1 for {A+C}, and the UE generates {{3, A+B+C}, {1, A+B}, {1, A+C}}, UE Reporting {{3, A+B+C}, {1, A+B}, {1, A+C}} to the base station, the base station receives {{3, A+B+C}, {1, reported by the UE. A+B}, {1, A+C}}, without decomposing {3, A+B+C}, directly obtain {A+B+C}, and decompose {1, A+B} to obtain {A}, {B}, and {A+B} of {1, A+B} itself, decompose {1, A+C} to get {A}, {C}, remove {A}, retain {C }, and {1, A+C}'s own {A+B}, whereby the base station acquires the set supported by the UE {{A+B+C}, {A+B}, {A+C}, {A },{B},{C}}.
