Description

Method, system and device for reporting carrier aggregation bandwidth capability

technical field

The present invention relates to the field of communication technologies, and in particular to a method, a system, a network side device and a terminal for reporting a carrier aggregation bandwidth capability of a terminal.

Background technique

At present, each carrier supported by the LTE-Advanced system adopts the basic bandwidth configuration of LTE, and the configuration supports 6 bandwidths of 1.4MHz, 3MHz, 5MHz, 10MHz, 15MHz, and 20MHz. Based on these 6 bandwidths, in the case of two carrier aggregations, there may be a total of 36 carrier aggregation bandwidth configuration modes, as shown in Table 1.

Table 1:

Carrier aggregation bandwidth (MHz) 20+20 20+15 20+10 ... 15+15 15+10 ... 1.4+1.4

For the terminal, due to software limitations, it cannot support various carrier aggregation bandwidths that may be generated by two carrier aggregations. This may cause some problems: For example, when the carrier aggregation bandwidth configured in the local carrier network is 20+20MHz, and the carrier aggregation bandwidth configured in the roaming carrier network is 20+15MHz, if the terminal only supports carrier aggregation of 20+20MHz bandwidth, after accessing the network of the roaming operator, because the carrier aggregation bandwidth configured in the roaming operator network does not match the carrier aggregation bandwidth supported by the terminal, the terminal cannot continue to work in multi-carrier aggregation mode, but only Can work in non-carrier aggregation mode. In this scenario, the terminal must send a notification message to the network side, so that the network side of the roaming operator network knows the carrier aggregation bandwidth that the terminal can support, so as to realize accurate scheduling of the terminal.

In the prior art, the terminal uses a terminal capability (UE Capability) message as the notification message. Corresponding to the 36 carrier aggregation bandwidths shown in Table 1, 36 bits can be used in the UE Capability message to carry the identifiers corresponding to the 36 carrier aggregation bandwidths. For any carrier aggregation bandwidth, the identifier may specifically be an identifier indicating whether the terminal supports the carrier aggregation bandwidth, as shown in Table 2 below.

Table 2:

Carrier aggregation bandwidth Indicates that the terminal supports carrier aggregation bandwidth identification Indicates that the terminal does not support carrier aggregation bandwidth identification 20+20 1 0 20+15 1 0 20+10 1 0 ... ... ... 1.4+1.4 1 0

Based on the corresponding relationship shown in Table 2, when a terminal supporting carrier aggregation bandwidth 20+20, 20+15, and 20+10 sends a UE Capability message to the network side, the identifier carried in the above 36 bits is "1110... 0". However, when a terminal supporting carrier aggregation bandwidth 20+20 sends a UECapability message to the network side, the identifier carried in the above 36 bits is "1000...0".

Using the above existing technology, the terminal needs to use 36 bits to notify the network side of the carrier aggregation bandwidth it supports, which requires a large space for information bearing. In addition, when the terminal determines the identifier to send, it needs to determine the identifiers corresponding to the carrier aggregation bandwidth supported by itself according to Table 2. If the terminal supports more carrier aggregation bandwidth, this method will consume more processing resources of the terminal. .

Detailed ways

In order to solve the problems of large occupied information carrying space and large processing resources consumed in the determination method of carrier aggregation bandwidth in the prior art, an embodiment of the present invention provides a solution for reporting the capability of a terminal to support carrier aggregation bandwidth. In this solution, the terminal carries the carrier aggregation bandwidth capability identifier of the terminal in the specified bits contained in the Feature Group Indicators (FGI, Feature Group Indicators) bits of the UE Capability message, so that the carrier aggregation bandwidth capability identifier of the terminal only occupies a small amount of information bearer space; at the same time, the above-mentioned terminals support carrier aggregation bandwidth capability identifiers can correspond to multiple carrier aggregation bandwidths (carrier aggregation bandwidth sets) at the same time, and the terminal does not need to determine the identifiers corresponding to the multiple carrier aggregation bandwidths it supports one by one, thus saving The processing resources of the terminal.

The solutions provided by the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

Embodiments of the present invention firstly provide a method for determining carrier aggregation bandwidth as shown in FIG. 1 , and the specific process of the method includes the following steps:

Step 11, the network side receives the UE Capability message sent by the terminal;

The TS36.331 standard defines the FGI bit of the information element (information element) of the UE Capability message. According to this definition, the FGI bits are composed of 32 bit sets in total, and the content carried by each bit is defined as an identifier used to indicate that the terminal supports a certain or some mandatory features. For example, for a certain mandatory feature, if it is verified through the test of the UE that it supports the mandatory feature, then the flag corresponding to the bit bearer of the mandatory feature is 1; and if it is verified that the UE does not support the mandatory feature , then the flag carried by this bit is 0.

In the embodiment of the present invention, in order to avoid making too many changes to the existing standard, it is considered that the FGI bit can be used to bear the carrier aggregation bandwidth capability identifier of the terminal.

Step 12, the network side obtains the carrier aggregation bandwidth capability identification of the terminal from the specified bits included in the FGI bit of the UE Capability message;

In order to reduce the information bearing space occupied by the carrier aggregation bandwidth capability identifier of the terminal, the number of specified bits mentioned here can generally be specified to be smaller than the predetermined total number of various carrier aggregation bandwidths supported by the communication system. For example, for the situation that 36 carrier aggregation bandwidths may appear in two carrier aggregations, the number of designated bits should be less than 36. Since the FGI bits are only 32 bits, in a case where 36 types of carrier aggregation bandwidths may appear, the entire FGI bits can actually be used to carry the carrier aggregation bandwidth capability identifier of the terminal. However, since the information carried by the first 28 bits of the FGI bits has been defined in the TS36.331 standard, the 29th to 32nd bits of the FGI bits are preferably used in the embodiment of the present invention to carry the carrier aggregation bandwidth capability of the terminal logo. Optionally, one or two bits of the 29th to 32nd bits may be used to carry the identifier. The specific implementation will be described in a specific embodiment later, and will not be repeated here.

Step 13: The network side determines the obtained carrier aggregation bandwidth capability of the terminal from the pre-agreed correspondence between the carrier aggregation bandwidth capability identifier of the terminal and the carrier aggregation bandwidth set supported by the terminal according to the obtained carrier aggregation bandwidth capability identification of the terminal Identifies the corresponding carrier aggregation bandwidth set.

In the embodiment of the present invention, the carrier aggregation bandwidth set supported by the terminal in the above correspondence relationship may not be limited to include: the carrier aggregation bandwidth set supported by the terminal's highest bandwidth support capability, and the carrier aggregation bandwidth set supported by the terminal's minimum bandwidth support capability bandwidth collection.

In the embodiment of the present invention, the carrier aggregation bandwidth capability identifier supported by the terminal corresponds to the carrier aggregation bandwidth set supported by the terminal. Since the carrier aggregation bandwidth set can contain one or more carrier aggregation bandwidths, even if the terminal supports multiple carrier aggregation bandwidths, these carrier aggregation bandwidths can only correspond to one terminal support carrier aggregation bandwidth capability identification, so it only needs to be executed once An operation of determining that the terminal supports the carrier aggregation bandwidth capability identifier. Different from the method in the prior art that requires the terminal to determine the identifiers corresponding to the carrier aggregation bandwidth it supports one by one, in the embodiment of the present invention, the method that one terminal supports the carrier aggregation bandwidth capability identifier corresponding to multiple carrier aggregation bandwidths can save the terminal The purpose of processing resources.

At the same time, for the transmission process on the terminal side, the embodiment of the present invention also provides another method for reporting the capability of the terminal to support carrier aggregation bandwidth, so as to solve the problem of large occupied information bearing space and costly information in the prior art carrier aggregation bandwidth reporting method. The problem of dealing with more resources. The method includes: first, the terminal bears the carrier aggregation bandwidth capability identifier of the terminal in specified bits included in the FGI bit of the terminal capability message; then, sends the terminal capability message to the network side.

The practical application of the solutions provided by the embodiments of the present invention will be described in detail below with a specific example.

In practical application, the carrier aggregation bandwidth supported by the terminal is defined in the radio frequency specification. For carrier aggregation in the Band40 frequency band, you can define the maximum bandwidth support capability of the terminal. The carrier aggregation bandwidth set supported includes: 20+20MHz, 20+10MHz, 15+15MHz, 20+15MHz, 20+5MHz; and the minimum bandwidth support capability The supported carrier aggregation bandwidth set includes: 20+20MHz, 20+10MHz.

For the carrier aggregation bandwidth sets respectively supported by the highest bandwidth support capability and the minimum bandwidth support capability, one bit may be selected from the FGI bits to carry the corresponding terminal support carrier aggregation bandwidth capability identifier. For example, the 29th bit of the FGI bit can be designated to carry the identifier. When the terminal adopts the highest bandwidth support capability, the flag is 1; otherwise, the flag is 0.

In addition to the division method of the carrier aggregation bandwidth set described above, four carrier aggregation bandwidth sets can also be divided according to the carrier aggregation bandwidth that may appear in the communication system. The carrier aggregation bandwidth contained in each set is as follows:

Carrier aggregation bandwidth set 1: 20+20MHz, 20+10MHz, 20+15MHz, 15+15MHz, 20+5MHz;

Carrier aggregation bandwidth set 2: 20+20MHz, 20+10MHz;

Carrier aggregation bandwidth set 3: 20+20MHz, 20+10MHz, 20+5MHz;

Carrier aggregation bandwidth set 4: 20+20MHz, 20+15MHz.

For the above four carrier aggregation bandwidth sets, two bits may be selected from the FGI bits to carry the corresponding terminal support carrier aggregation bandwidth capability identifier. For example, the 30th and 31st bits of the FGI bits may be designated to carry the identifier. Specifically, the identifier "00" may indicate carrier aggregation bandwidth set 1; the identifier "01" may indicate carrier aggregation bandwidth set 2; the identifier "10" may indicate carrier aggregation bandwidth set 3; the identifier "11" may indicate carrier aggregation bandwidth set 4 . In addition, only one bit may be selected among the FGI bits to bear the corresponding terminal support carrier aggregation bandwidth capability identifier. For example, the 32nd bit of the FGI bit may be designated to carry the identifier. Specifically, the identifier "0" may represent all aggregated carrier bandwidths in carrier aggregation bandwidth sets 1 and 2; the identifier "1" may represent all aggregated carrier bandwidths in carrier aggregation bandwidth sets 3 and 4.

Based on the above settings, assuming that a terminal supporting bandwidth set 1 roams to a certain cell, the network-side device (base station in this scenario) determines the carrier aggregation bandwidth of the terminal as shown in Figure 2, including:

Step 21, the terminal determines that the carrier aggregation bandwidth supported by itself is the above-mentioned carrier aggregation bandwidth set 2 by reading the factory setting information stored in the terminal, that is, 20+20MHz, 20+10MHz;

Step 22, the terminal determines that the identifier corresponding to the carrier aggregation bandwidth set 2 is 01 according to the corresponding relationship between the pre-agreed carrier aggregation bandwidth and the carrier aggregation bandwidth capability identifier supported by the terminal;

Step 23, the terminal sends the identity 01 carried in the 30th and 31st bits of the FGI bits of the UE Capability message to the base station;

Step 24, after receiving the UE Capability message, the base station parses out the identifier 01 from the 30th and 31st bits of the FGI bits;

Step 25, the base station determines the carrier aggregation bandwidth set corresponding to the identifier 01: 20+20MHz, 20+10MHz according to the correspondence between the pre-agreed carrier aggregation bandwidth and the carrier aggregation bandwidth capability identifier supported by the terminal;

Step 26, the base station schedules the terminal according to the determined carrier aggregation bandwidth set.

In step 26, if the carrier aggregation bandwidth supported by the network side is 20+20MHz, after determining that the terminal supports the corresponding carrier aggregation bandwidth, the base station executes the scheduling method under carrier aggregation—such as configuring the primary and secondary carriers for the terminal, Perform resource scheduling and the like for the terminal on two 20MHz carriers at the same time.

If the carrier aggregation bandwidth supported by the network side is 20+15MHz, after determining that the terminal does not support the corresponding carrier aggregation bandwidth, the base station cannot schedule the terminal according to the carrier aggregation method, but can only schedule the terminal to a certain carrier. Make it work in the form of non-carrier aggregation, so as to prevent the abnormality from exceeding the terminal capability. For example, the terminal can be scheduled to work on one of the two carriers according to the service request of the terminal. If the service volume corresponding to the service request of the terminal is very large, the terminal can be scheduled to work on the 20MHz carrier; or the terminal can be reasonably scheduled according to the load conditions of the two carriers supported by the network side.

Corresponding to the method for determining the carrier aggregation bandwidth provided by the embodiment of the present invention, the embodiment of the present invention also provides a system for determining the carrier aggregation bandwidth, which is used to solve the problem that the carrier aggregation bandwidth determination method in the prior art has a relatively large occupied information bearing space.
