Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a method, terminal and device for reporting and receiving a position of a direct current component carrier. Background Art

[0002] The OFDM (Orthogonal Frequency Division Multiplexing) system uses a zero intermediate frequency receiver. In order to avoid interference caused by local oscillator leakage, the uplink transmission in 4G technology is offset by 7.5KHz to avoid interference caused by the uplink DC (Direct Current) carrier. 5G technology uses OFDM signals for uplink, and the baseband signal is not offset by 7.5KHz. At the same time, due to the flexible transmission bandwidth (such as bandwidth part BWP, etc.), no additional processing is done on the uplink carrier offset, but the terminal reporting method is introduced to help the network confirm the position of the DC carrier. The terminal reports the DC carrier position on each BWP of each cell. The network uses this information to determine the DC carrier position, and then avoids interference by punching holes in the corresponding carrier position and avoiding scheduling.

[0003] The terminal informs the network of the possible location of the DC carrier by reporting the location of the DC carrier on each serving cell BWP. For example, if a cell has 4 BWPs, the DC carrier location corresponding to the 4 BWPs of this cell is reported; if the terminal is in carrier aggregation mode and has 2 or more serving cells, the terminal reports the DC carrier location of the BWP corresponding to each serving cell.

[0004] However, in the carrier aggregation mode, the existing DC location reporting method will cause problems. In the intra-band carrier aggregation scenario, considering different terminal implementations, some terminals use one RF channel to implement uplink carrier aggregation, and some terminals use multiple sets of RF channels to implement uplink carrier aggregation. For terminals that use one set of RF channels for each carrier, they can reuse the current standard method to report the DC location of each BWP in each service cell; however, for terminals that use one RF channel or multiple carriers share one RF channel to implement uplink carrier aggregation, the existing method of reporting DC location through each BWP in each service cell cannot be used. Summary of the invention

[0005] The present invention provides a method, terminal and device for reporting and receiving the locations of direct current component carriers (Tx Direct Current locations), which can improve the uplink performance of carrier aggregation.

[0058] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0059] like Figure 1 As shown, an embodiment of the present invention provides a method for reporting the position of a DC component carrier, which is applied to a terminal, and the method includes:

[0060] Step 11: reporting the position of the DC component carrier in the case of the bandwidth part BWP combination of the carrier aggregation.

[0061] If in the carrier aggregation scenario, there may be multiple possible terminal implementation solutions, such as Figure 2 , Figure 3 as well as Figure 4As shown in FIG. 1 , the DC position reporting mode of the terminal under the flexible BWP configuration affects the uplink performance of carrier aggregation, especially the uplink transmission under high-order modulation, where: Figure 2 In the example, BWP3 of cell 1 and BWP1' of cell 2 share a radio frequency channel; Figure 3 In the example, BWP1 of cell 1 and BWP of cell 2 use independent radio frequency channels; Figure 4 In the embodiment of the present invention, the BWP4 of cell 1 and the BWP1' of cell 2 share a radio frequency channel. In the embodiment of the present invention, the serving cell includes a primary cell and a secondary cell, and the BWP combination of carrier aggregation is the BWP combination of the serving cell.

[0062] This embodiment of the present invention can improve the carrier aggregation uplink performance by reporting the position of the DC component carrier in the case of BWP combination.

[0063] In an optional embodiment of the present invention, the above step 11 may include:

[0064] If the terminal does not report the position of the DC component carrier independently, it reports the position of the DC component carrier in the case of the bandwidth part BWP combination of carrier aggregation; wherein, reporting the position of the DC component carrier independently includes: reporting the position of a DC component carrier in a bandwidth part BWP of a cell or a carrier.

[0065] In an optional embodiment of the present invention, the above step 11 may include:

[0066] Step 111, reporting the positions of the DC component carriers corresponding to all BWP combinations of the current multiple service cells of the terminal; all BWP combinations of the multiple service cells here include: in the case of a combination of multiple cells, the combination of the BWP of each cell with any BWP of other cells, for example, the combination of BWP1 of cell 1 and BWP1' of cell 2, the combination of BWP1 of cell 1 and BWP2' of cell 2, the combination of BWP1 of cell 1 and BWP3' of cell 2, the combination of BWP1 of cell 1 and BWP4' of cell 2, and similarly, the combination of BWP2 of cell 1 and BWP1' of cell 2, the combination of BWP2 of cell 1 and BWP2' of cell 2, the combination of BWP2 of cell 1 and BWP3' of cell 2, the combination of BWP2 of cell 1 and BWP4' of cell 2, etc.; or,

[0067] Step 112, reporting or determining a window range in the frequency domain, when the BWP combination is within the window range, based on the BWP combination, reporting the position of the DC component DC carrier is the middle position of the window; or, when the BWP combination is outside the window range, reporting the position of the DC component DC carrier independently.

[0068] In the above embodiments of the present invention, the BWP combination is represented by a serving cell index and a BWP ID.

[0069] In the above embodiment of the present invention, the position of the DC component carrier is represented by a subcarrier index.

[0070] In an optional embodiment of the present invention, the method for reporting the position of the DC component carrier may further include: if the configuration of the bandwidth part BWP is updated, then based on the updated BWP combination, updating the position of the DC component carrier.

[0071] In an optional embodiment of the present invention, updating the position of the DC component carrier includes:

[0072] The position of the DC component DC carrier is updated periodically.

[0073] In an optional embodiment of the present invention, reporting the position of the DC component carrier includes:

[0074] The position of the DC component carrier is reported through radio resource control RRC signaling.

[0075] The implementation of step 111 may specifically include:

[0076] 1111) The network configures the terminal to report the DC location information of the carrier aggregation;

[0077] 1112) The terminal traverses all possible BWP combinations of the carrier aggregation serving cell and reports the DC location of all serving cell BWP combinations, where the location of the DC location is less than or equal to the number of BWPs in the BWP combination; the BWP combination can be indicated by the serving cell index (ServCellIndex) and the BWP ID; the DC location (Tx Direct Currentlocations) is indicated by the subcarrier index;

[0078] Take two cells as an example. The cells are configured with BWP1, BWP2, BWP3, and BWP4. Cell 2 is configured with BWP1'BWP2'BWP3'BWP4'. The terminal reports:

[0079] In the case of BWP1+BWP1', DC location (Tx Direct Current locations), DC location In the case of BWP1+BWP2', DC location (location);

[0080] In the case of BWP1+BWP3', DC location;

[0081] In the case of BWP1+BWP4', DC location;

[0082] In the case of BWP2+BWP1', DC location;

[0083] In the case of BWP2+BWP2', DC location;

[0084] In the case of BWP2+BWP3', DC location;

[0085] In the case of BWP2+BWP4', DC location;

[0086] In the case of BWP3+BWP1', DC location;

[0087] In the case of BWP3+BWP2', DC location;

[0088] In the case of BWP3+BWP3', DC location;

[0089] In the case of BWP3+BWP4', DC location;

[0090] In the case of BWP4+BWP1', DC location;

[0091] In the case of BWP4+BWP2', DC location;

[0092] In the case of BWP4+BWP3', DC location;

[0093] In the case of BWP4+BWP4', DC location;

[0094] There are 16 cases in total, and the DC carrier position in each case

[0095] The current protocol only supports 4 BWPs per cell, and only 1 BWP can be activated at the same time; the current protocol supports carrier aggregation of 16 carriers

[0096] 1113) The network determines the DC position according to its currently activated BWP. At the DC position, the network may not schedule the terminal to send uplink, thereby avoiding interference caused by local oscillator leakage and improving the uplink carrier aggregation SNR and high-order modulation performance;

[0097] 1114) If the network updates the BWP configuration, the terminal updates the DC position in 1112);

[0098] 1115) The network configures the terminal to periodically update the DC location information.

[0099] The implementation of the above step 112 may specifically include:

[0100] The current protocol can support carrier aggregation of 16 carriers. If each cell is configured with 4 BWPs, the reporting combination will increase exponentially (4^16). Here, a more general way to save overhead is adopted:

[0101] 1121) The network configures the terminal to report the DC location information of the carrier aggregation;

[0102] 1122) Whether the terminal reports an independent DC location;

[0103] 1123) The range of the terminal reporting the DC position, the range is a frequency domain window, as long as the activated BWP combination is within this window, it means that the terminal has only one DC position, if it exceeds this window, it means independent DC position. The window can be an absolute frequency domain window or a relative frequency domain bandwidth window;

[0104] The terminal can report a bandwidth range to inform the network that when the frequency domain resources of the aggregated BWP are within a certain bandwidth range window, the terminal has only one DC location. This bandwidth is determined by the bandwidth of the RF channel or the bandwidth of the power amplifier, such as 100MHz, 150MHz, 200MHz or full bandwidth (full bandwidth means the bandwidth of the aggregated carrier under carrier aggregation), and this window is relative bandwidth and can slide, indicating that the RF channel or power amplifier of the terminal can also slide. Taking 100MHz as an example, it means that there is only one DC location within the range of 100MHz. If it exceeds 100MHz, it is an independent DC location.

[0105] For example, Figure 4 In the figure, when BWP4 of cell 1 and BWP1′ of cell 2 are activated simultaneously, there is only one DC position, which is at the center of BWP4+BWP1′;

[0106] like Figure 5 As shown, when BWP4 of cell 1 and BWP2' of cell 2 are activated at the same time, there are two DC positions, which are respectively in the middle of BWP4 and BWP2'.

[0107] The terminal can report an absolute frequency domain range to inform the network that there is only one DC position within the frequency domain range of the aggregated BWP. This frequency domain range is determined by the frequency domain range supported by the RF channel or the frequency domain range supported by the power amplifier. The frequency domain range can be a determined frequency position or subcarrier index. For example, the frequency domain range is from cell 1 subcarrier index 10 to cell 2 subcarrier index 300. If it exceeds this range, it is an independent DC position. If it does not exceed this range, it is 1 DC position.

[0108] 1124) For the case where the DC position is not independent, the terminal reports the DC position under the serving cell BWP combination (falls back to the traversal mode of reporting);

[0109] Independent DC location means that the DC location of each serving cell is independent, i.e., each cell reports the DC location of each BWP;

[0110] 1125) For the case where the DC position is not independent, the terminal reports the DC position under the serving cell BWP combination;

[0111] For example, Figure 6 As shown, when the terminal reports more than 100MHz, it is an independent DC position. Then the terminal also needs to report the DC position of the following combination;

[0112] In the case of BWP2+BWP1', DC position;

[0113] In the case of BWP3+BWP1', DC position;

[0114] In the case of BWP3+BWP2', DC position;

[0115] 1126) The network determines the DC position based on its currently activated BWP. At the DC position, the network may not schedule the terminal to send uplink, thus avoiding interference caused by local oscillator leakage and improving the uplink carrier aggregation SNR and high-order modulation performance.

[0116] 1127) If the network updates the BWP configuration, the terminal updates the DC position in 1124, 1125;

[0117] 1128) The network configuration terminal periodically updates the DC location information. When updating, only the specific location of the DC location (the information in 1124 and 1125) is updated. There is no need to update the independent DC location information (the information in 1122 and 1123).

[0118] The above-mentioned embodiments of the present invention report the position of the DC carrier through a combination based on BWP, thereby solving the impact of the uplink DC component in the case of terminal carrier aggregation and improving the uplink performance of carrier aggregation.
