Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
As described in the background art, in the related art, when a terminal reports UE capacity to a network side, the carrier aggregation capability and the multi-antenna capability of the terminal are respectively indicated by a ca-bandwidth csdl field and a supported mimo-capability dl field.
However, due to the limitation of the radio frequency and baseband processing capability of the terminal itself, some terminals are of the multi-antenna technology that do not support some carrier combinations, i.e. support downlink continuous multi-carrier aggregation, some carriers support downlink multi-stream, and other carriers support 2-stream, e.g. support 4-stream, 2-stream and 4-stream transmission on three simultaneous continuous carriers, i.e. support carrier 1 (4-stream) + carrier 2 (4-stream) + carrier 3 (2-stream) or carrier 1 (2-stream) + carrier 2 (4-stream) + carrier 3 (4-stream), in this case, when the terminal reports its capability, it still indicates its carrier aggregation capability and multi-antenna capability through the ca-bandwidthcsdl field and the supported mimo-capability dl field, respectively, however, when it indicates its carrier aggregation capability and multi-antenna capability through the ca-bandwidthcsdl field and the supported mimo-capability dl field, only partial sequential layer combination can be achieved, and the carrier aggregation capability and the multi-antenna capability of the terminal cannot be accurately reflected, so that the network side cannot accurately configure carrier resources for the terminal according to the UE capacity.
For example, suppose that a terminal reports that it supports B41 (frequency band) downlink continuous three-carrier aggregation, and two continuous carriers are downlink 4 streams, and another carrier is 2 streams (because the terminal radio frequency has a requirement on bandwidth, some terminals do not support some combined multi-antenna technologies, for example, the terminal does not support 4 streams, 2 streams, and 4 streams on three continuous carriers at the same time), that is, carrier 1(4 streams) + carrier 2(4 streams) + carrier 3(2 streams), or carrier 1(2 streams) + carrier 2(4 streams) + carrier 3(4 streams), is simply expressed as 442 or 224, and the following description is made according to a simple expression of numbers.
However, the intraBandContiguousCC-InfoList-r12 field does not represent the supported order of the layer number combinations. Therefore, when the terminal reports in this way, the network side will understand that the terminal supports any two carriers as 4 streams, and the other carrier as 2 streams. This obviously does not match the actual capabilities of the terminal. This will occur: the network side can carry out configuration according to the maximum capability reported by the terminal understood by the network side, and configuration failure can occur at the moment; after the network side finds that the configuration is failed, all carriers may be configured as 2 streams, so that the maximum capability of the terminal cannot be exerted, an expected effect cannot be achieved, and user experience is affected.
Based on this, in various embodiments of the present invention, the terminal places the first information and the second information in a message for reporting the carrier aggregation capability of the terminal; the first information is used for indicating M continuous carriers which can be aggregated and are supported by the terminal, and P-layer data transmission is supported on N carriers in the M carriers; m is an integer greater than or equal to 3; n is an integer greater than or equal to 2; n is less than M; p is an integer greater than 2; the second information is used for indicating the positions of the frequency points of the N carriers in the M continuous carrier frequency points; the first information and the second information can indicate a layer number combination sequence supported by the terminal under continuous carrier aggregation; sending the message for reporting the carrier aggregation capability of the terminal to a network side; the network equipment determines M continuous carriers which can be aggregated and are supported by the terminal by utilizing the first information, and P-layer data transmission is supported on N carriers in the M carriers; determining the positions of the frequency points of the N carriers in the M continuous carrier frequency points by using the second information; and determining the layer number combination sequence supported by the terminal under the continuous carrier aggregation by using the first information and the second information.
According to the scheme provided by the embodiment of the invention, the first information and the second information are combined to indicate the supported layer number combination sequence of the terminal under the continuous carrier aggregation, so that the capability (carrier aggregation capability) of the terminal can be accurately reported when the terminal supports the continuous multi-carrier aggregation and part of carriers support multi-stream, and the network side can accurately understand the capability of the terminal.
An embodiment of the present invention provides a method for processing terminal capability, which is applied to a terminal, and as shown in fig. 1, the method includes:
step 101: placing the first information and the second information in a message for reporting the carrier aggregation capability of the terminal;
here, the first information is used to indicate that the terminal supports M contiguous carriers capable of being aggregated, and supports P-layer data transmission on N carriers of the M carriers; the second information is used for indicating the positions of the frequency points of the N carriers in the M continuous carrier frequency points; the first information and the second information can indicate a layer number combination order supported by the terminal under continuous carrier aggregation.
That is, the terminal indicates the combination order of the number of layers supported by the terminal under the continuous carrier aggregation by combining the first information and the second information.
Wherein M is an integer greater than or equal to 3; n is an integer greater than or equal to 2; n is less than M; p is an integer greater than 2.
In an embodiment, the second information is used to indicate whether N carriers are continuous and whether a frequency point of a carrier supporting P-layer data transmission belongs to an edge frequency point of M continuous carrier frequency points.
In practical application, the terminal generally reports its own capability through an RRC message, and for the downlink carrier aggregation capability, the ca-bandwidth csdl field is generally used for indication.
Based on this, in an embodiment, the specific implementation of this step may include:
setting a ca-BandwidthClassDL field of an RRC message by using the first information; and adding corresponding indication bit identification in the ca-BandwidthClassDL field by using the second information.
That is, similar to the related art, the terminal sets the first information in the ca-bandwidth cslasdl field, and further adds a corresponding indication bit identifier in the ca-bandwidth csdl field using the second information, thereby indicating the order of the number of layer combinations supported by itself under the contiguous carrier aggregation, that is, all the number of layer combinations supported, by combining the first information and the second information.
For the indication bit identification, it can be set as required. For example, a field "lack-layers" may be introduced into the ca-bandwidth csdl field, and then the supportable layer combination order of the terminal may be reported by combining intra-band non-contiguous carrier aggregation with the field. The rock-layers may be 2 bits (bits), that is, the rock-layers may be fields consisting of two bits, assuming bit1 and bit2 in order from high to low.
How to use the stack-layers to indicate whether the N carriers are continuous and whether the frequency point of the carrier supporting P-layer data transmission belongs to the edge frequency point of the M continuous carrier frequency points is described in detail below.
As shown in fig. 2, in practical application, considering the limitation of the terminal radio frequency unit, for example, considering that only one radio frequency unit supports a higher stream number, such as 4 streams, and the like, and the other radio frequency unit only supports 2 streams, whether a carrier frequency supporting 4 streams is continuously required or not is indicated by bit1, that is, bit1 represents whether a frequency point supporting P streams (multiple streams) is continuously required or not.
Meanwhile, considering the limitation of the baseband processing capability, there may be a case that the same radio frequency channel supporting multiple streams (for example, 4 streams) only supports partial carrier frequencies to support higher stream numbers for multiple streams such as RF1, but the baseband processing capability is poor, so that only N continuous carrier frequencies in M carriers can support higher stream numbers, and the remaining M-N carriers only support 2 streams, that is, represented by bit2, that is, the bit2 represents that in the supported combination, except for requiring that N carrier frequencies supporting P streams are continuous, a frequency point allowed to support 4 streams is not an edge frequency point in carrier aggregation.
Specific meanings of bit1 and bit2 values shown in table 1 can be obtained according to the two requirements.
TABLE 1
This is illustrated below in conjunction with fig. 2 and table 1.
Assuming that X is 3, a is 2, B is 1, and the carrier frequency in RF1 of the radio frequency unit is required to be continuous, then only 442, 244, and not 424 are supported. Meanwhile, in the supported combination, 2 carrier frequencies supporting 4 streams are required to be continuous, and the frequency points supporting 4 streams are also required to belong to edge frequency points in carrier aggregation, so that specific meanings of bit1 and bit2 values in table 1 are combined, that is, bit1 is 0 and bit2 is 0, that is, lack-layers is 00.
For another example, assuming that X is 5, a is 3, B is 2, and RF1 of the radio frequency unit supports only 2 carrier frequency 4 streams, 24422, 44222, 22244, 22442 are supported, and 42422, 42242, 22424, 42224, etc. are not supported, so that, in combination with the specific meanings of bit1 and bit2 in table 1, bit1 is 0 and bit2 is 1, that is, lack-layers is 01.
For example, the above downlink continuous three-carrier aggregation supports an example in which two continuous carriers are 4 streams and the other carrier is 2 streams. The terminal reporting mode is as follows:
then, specific values of bit1 and bit2 in the lack-layers shown in Table 2 can be obtained by combining specific flow numbers.
TABLE 2
Among them, it should be noted that: for example 1, 244 refers to the order of consecutive carrier frequencies, the first carrier supporting 2 streams, the second and third supporting 4 streams.
It should be noted that: in practical applications, two bits may be used to respectively indicate corresponding meanings (i.e. to respectively indicate the meanings characterized by bit1 and bit 2), or two different parameter names may be used to respectively indicate corresponding meanings, which is not limited in the embodiment of the present invention.
In practical application, the carrier aggregation capability of the mobile terminal can be reported to the network side, and the multi-antenna capability of the mobile terminal can also be reported to the network side.
Based on this, in an embodiment, when the first information and the second information are placed in a message for reporting carrier aggregation capability of the terminal, the method may further include:
placing the third information in the message for reporting the carrier aggregation capability of the terminal; the third information is used for indicating the number of layers of transmission data supported by each antenna of the terminal.
Here, in actual use, the terminal sets a supported mimo-capability dl field of an RRC message using the third information.
Step 102: and sending the message for reporting the carrier aggregation capability of the terminal to a network side.
Correspondingly, an embodiment of the present invention further provides a method for processing terminal capabilities, which is applied to a network device, and as shown in fig. 3, the method includes:
step 301: receiving a message which is sent by a terminal and used for reporting the carrier aggregation capability of the terminal;
step 302: analyzing the message for reporting the carrier aggregation capability of the terminal to obtain first information and second information;
here, in an embodiment, the network device receives an RRC message sent by the terminal;
analyzing a ca-BandwidthClassDL field of the RRC message to obtain the first information; and obtaining the second information according to the indication bit mark added in the ca-Bandwidth ClassDL field.
In practical application, the carrier aggregation capability of the mobile terminal can be reported to the network side, and the multi-antenna capability of the mobile terminal can also be reported to the network side.
Based on this, in an embodiment, the network device analyzes the message for reporting the terminal carrier aggregation capability, and further obtains third information;
and the network equipment determines the number of layers of transmission data supported by each antenna of the terminal by using the third information.
Here, in actual application, the terminal may set a supported mimo-capability dl field of the RRC message using the third information.
Correspondingly, the network device analyzes the supported mimo-capability dl field of the RRC message to obtain the third information.
In practical application, the network device may be a base station, or may be other access network devices.
Step 303: determining M continuous carriers which can be aggregated and are supported by the terminal by using first information, and supporting P-layer data transmission on N carriers in the M carriers; determining the positions of the frequency points of the N carriers in the M continuous carrier frequency points by using the second information;
