Description
Technical Field
The present disclosure relates to the field of communications technologies, and in particular, to an information transmission method NR base station, NR terminal, and storage medium.
Background
The dynamic spectrum sharing technology (DSS, dynamic Spectrum Sharing, also called LTE-NR coexistence technology in the 3gpp RAN4 standard) between LTE (Long Term Evolution )/NR (New Radio) is one of the important features introduced in the early deployment of the current 5G network in order to save the cost of building a station and deployment time. The essence of the method is that LTE and NR share the same frequency spectrum, and a network side allocates resources for a terminal to carry out 4G/5G transmission.
In the above scenario, the 4G LTE neighbor cell has larger interference to the data transmission of the cell. With the gradual network-withdrawal of the 4G LTE, the occurrence of downlink data in neighboring cells gradually decreases, but the downlink cell-specific reference signals (CRS, cell Reference Signal) which are normally open and occupy fixed resources in LTE still cause larger interference to the 5G NR terminal in the present cell in a relatively long period of time in the future.
It should be noted that the information disclosed in the above background section is only for enhancing understanding of the background of the present disclosure and thus may include information that does not constitute prior art known to those of ordinary skill in the art.

Fig. 1 is a flowchart illustrating an information transmission method according to an exemplary embodiment.
As shown in fig. 1, the information transmission method provided in the embodiment of the present disclosure may include step S102.
In step S102, if the NR terminal supports multiple LTE neighbor cell CRS (Cell Reference Signal ) interference suppression capabilities, the NR terminal reports the interference suppression capabilities to the NR base station.
In the embodiment of the disclosure, an NR base station may initiate a capability query request to an NR terminal, where the NR terminal may receive the capability query request, and if the NR terminal supports interference suppression capability, the NR terminal may report the interference suppression capability of the terminal to the NR base station according to the capability query request.
In the embodiments of the present disclosure, an NR terminal may support multiple interference scenarios, where multiple interference scenarios may refer to two or more interference scenarios, and in the following description, two interference scenarios (i.e., a first interference scenario and a second interference scenario) are taken as examples, but the present disclosure is not limited thereto.
The terminal supporting interference suppression can better suppress the interference of the CRS through measurement, estimation and equalization algorithms.
In an exemplary embodiment, the above-described interference suppression capability may include at least two of a first interference suppression capability, a second interference suppression capability, a third interference suppression capability, a fourth interference suppression capability, a fifth interference suppression capability, a sixth interference suppression capability, a seventh interference suppression capability, and an eighth interference suppression capability (hereinafter may be simply referred to as "capability 1" to "capability 8").
The first interference suppression capability may be an interference suppression capability of the NR terminal supporting the first receiving algorithm based on the network signaling assistance in the first interference scenario, the second interference suppression capability may be an interference suppression capability of the NR terminal supporting the first receiving algorithm based on the network signaling assistance in the first interference scenario, the third interference suppression capability may be an interference suppression capability of the NR terminal supporting the second receiving algorithm based on the network signaling assistance in the first interference scenario, the fourth interference suppression capability may be an interference suppression capability of the NR terminal supporting the second receiving algorithm based on the network signaling assistance in the first interference scenario, the fifth interference suppression capability may be an interference suppression capability of the NR terminal supporting the second receiving algorithm based on the network signaling assistance in the second interference scenario, the sixth interference suppression capability may be an interference suppression capability of the NR terminal supporting the first receiving algorithm based on the network signaling assistance in the second interference scenario, the seventh interference suppression capability may be an interference suppression capability of the NR terminal supporting the second receiving algorithm based on the second interference suppression algorithm based on the second interference scenario, the second interference suppression capability of the NR terminal supporting the network signaling assistance in the second interference scenario.
In the embodiment of the present disclosure, the first interference scenario (may also be referred to as interference scenario 1) may be that the terminal receives LTE interference from the serving base station, and the terminal receives LTE CRS interference of the neighboring cell; the second interference scenario (which may also be referred to as interference scenario 2) may be that the terminal only receives neighbor LTE CRS interference.
In the embodiment of the disclosure, the interference suppression capability based on the first receiving algorithm may be a neighboring CRS interference cancellation capability, and the interference suppression capability based on the second receiving algorithm may be an interference suppression capability based on LLR weighting (Log Likelihood Ratio weighting, log likelihood ratio weight adjustment).
Specifically, the base station may initiate capability query to the NR terminal through RRC signaling specified by the protocol, and the terminal supporting the CRS interference suppression related capability of the neighboring cell in the LTE NR coexistence scenario may report at least two of the following terminal capabilities to the base station:
capability 1: the terminal supports 'neighbor cell CRS interference elimination' without network signaling assistance under the interference scene 1;
capability 2: the terminal supports 'neighbor cell CRS interference elimination' which requires network signaling assistance under the interference scene 1;
capability 3: the terminal supports 'LLR weighting-based interference suppression' without network signaling assistance under interference scene 1;
Capability 4: the terminal supports 'LLR weighting-based interference suppression' which requires network signaling assistance under an interference scene 1;
capacity 5: the terminal supports 'neighbor cell CRS interference elimination' without network signaling assistance under the interference scene 2;
capability 6: the terminal supports 'neighbor cell CRS interference elimination' which requires network signaling assistance under the interference scene 2;
capability 7: the terminal supports 'LLR weighting-based interference suppression' without network signaling assistance under interference scene 2;
capacity 8: the terminal supports 'LLR weighting-based interference suppression' of 'network signaling assistance' under interference scenario 2.
In an exemplary embodiment, the above-described interference suppression capability may further include a ninth interference suppression capability (hereinafter, abbreviated as capability 9); the ninth interference suppression capability is the number of NR carriers for suppressing the maximum neighbor cell CRS interference supported by the NR terminal in the carrier aggregation scene.
In an exemplary embodiment, if the first interference suppression capability, the second interference suppression capability, the third interference suppression capability, the fourth interference suppression capability, the fifth interference suppression capability, the sixth interference suppression capability, the seventh interference suppression capability, and the eighth interference suppression capability are represented by values, the values may simultaneously represent the number of NR carriers of the maximum neighbor cell CRS interference suppression that the NR terminal can support in the carrier aggregation scenario.
Specifically, the terminal may report one or more of the following capabilities on the basis of reporting at least one of the above capabilities 1 to 8 to the base station:
capability 9: the number of NR cells for the maximum neighbor cell CRS interference suppression supported by the terminal in the carrier aggregation scene;
capacity 10: and when the NR subcarrier interval is 30k, whether the terminal supports adjacent cell LTE CRS interference suppression or not.
The number of NR cells in "capability 9" (i.e., the number of NR cells with maximum neighbor CRS interference suppression supported by the terminal in a carrier aggregation scenario) may also be reported by the values of "capability 1 to capability 8" at the same time.
In the embodiment of the disclosure, the "capability 1 to capability 8" reported by the terminal to the base station may be a True/False, or may be a value, so long as the value exists, the reporting of the "capability 1 to capability 8" can be considered, and meanwhile, the value may also represent the number of NR cells that can be supported by the terminal in the "capability 9" under the carrier aggregation scenario and have the greatest adjacent cell CRS interference suppression.
In an exemplary embodiment, the reporting granularity of the interference suppression capability is a frequency range (frequency range), a duplex mode (duplex mode) and a subcarrier (sub carrier spacing) supported by the NR terminal, and/or a frequency band supported by the NR terminal.
That is, the reporting granularity of the interference suppression capability may be a frequency band supported by the NR terminal, the reporting granularity of the interference suppression capability may be a frequency range supported by the NR terminal, a duplex mode, and a subcarrier, and the reporting granularity of the interference suppression capability may also be a frequency band supported by the NR terminal, a frequency range supported by the NR terminal, a duplex mode, and a subcarrier.
Specifically, the NR terminal may report the interference suppression capability of the NR terminal according to the frequency band supported by the NR terminal.
For example, the NR terminal supports the band a, the band B, and the band C, the NR terminal supports the "capability 1" and the "capability 5" for the band a, the NR terminal supports the "capability 3" for the band B, the NR terminal does not support the interference suppression capability for the band C, the NR terminal may report the capability supported for the band a alone, report the capability supported for the band B alone, the NR terminal does not support the interference suppression capability for the band C, and the interference suppression capability may not be reported for the band C.
Specifically, the NR terminal may report the interference suppression capability for the frequency range, duplex mode and subcarrier supported by the NR terminal, that is, it may be considered that the NR terminal supports the same interference suppression capability in all supported frequency bands of the frequency range, duplex mode and subcarrier supported by the NR terminal (for example, FR1, TDD, 30 kHz).
For example, the NR terminal reports to the base station all interference suppression capabilities supported by the NR terminal.
In an exemplary embodiment, the number of interference suppression capabilities includes a first interference suppression capability, then the NR base station defaults to the NR terminal while supporting a second interference suppression capability; or, if the plurality of interference suppression capabilities include the third interference suppression capability, the NR base station defaults to the NR terminal and simultaneously supports the fourth interference suppression capability; or, if the plurality of interference suppression capabilities include a fifth interference suppression capability, the NR base station defaults to the NR terminal and simultaneously supports the sixth interference suppression capability; alternatively, the number of interference suppression capabilities includes a seventh interference suppression capability, then the NR base station defaults to the NR terminal supporting the eighth interference suppression capability simultaneously.
Specifically, reporting a terminal supporting 'neighbor cell CRS interference cancellation without network signaling assistance' (capability 1), the network may default that the terminal supports interference suppression based on network signaling assistance in the same interference scenario at the same time, for example, if the terminal reports supporting capability 1, the base station may default that the terminal supports capability 2 at the same time; if the terminal reports the supporting capability 3, the base station can default the terminal to simultaneously support the capability 4; if the terminal reports the supporting capability 5, the base station can default the terminal to simultaneously support the capability 6; if the terminal reports the supporting capability 7, the base station can default the terminal to support the capability 8 at the same time.
The above capabilities 1-10 may be defined in the TS 38.306 and TS 38.331 standards.
Fig. 2 is a flowchart illustrating another information transmission method according to an exemplary embodiment.
As shown in fig. 2, the information transmission method provided in the embodiment of the present disclosure may include step S202 on the basis of fig. 1.
In step S202, if the several interference suppression capabilities include at least one of the first interference suppression capability, the second interference suppression capability, the third interference suppression capability, and the fourth interference suppression capability and only include the second interference suppression capability and the fourth interference suppression capability, the NR base station in the first interference scenario instructs the NR terminal to turn on or off the neighbor CRS interference suppression function; and if the plurality of interference suppression capabilities are included in the fifth interference suppression capability, the sixth interference suppression capability, the seventh interference suppression capability and the eighth interference suppression capability and only include at least one of the sixth interference suppression capability and the eighth interference suppression capability, the NR base station in the second interference scene instructs the NR terminal to turn on or off the adjacent cell CRS interference suppression function.
Specifically, for the terminals with only reporting supporting capability 2/4/6/8 (and/or relation) in the above capabilities 1 to 8, the base station indicates that neighboring cell LTE CRS interference exists in the terminal network by one of the following modes, and simultaneously indicates that the terminal turns on or off the neighboring cell CRS interference suppression function.
In an exemplary embodiment, if several interference suppression capabilities are included in the first interference suppression capability, the second interference suppression capability, the third interference suppression capability and the fourth interference suppression capability and include only the second interference suppression capability and/or the fourth interference suppression capability, the NR base station in the first interference scenario uses LTE CRS rate matching signaling (LTE-CRS-to-interference) of the terminal, and implicitly instructs the NR terminal to turn on the neighbor CRS interference suppression function.
Specifically, for a terminal that only supports capability 2 and/or capability 4 in capability 1, capability 2, capability 3 and capability 4, the base station may use LTE-CRS-to-match signaling defined in TS38.331 to implicitly instruct the terminal to simultaneously start the neighbor cell CRS interference suppression function.
In an exemplary embodiment, if several interference suppression capabilities are included in the fifth interference suppression capability, the sixth interference suppression capability, the seventh interference suppression capability, and the eighth interference suppression capability, and include only the sixth interference suppression capability and/or the eighth interference suppression capability, the NR base station in the second interference scenario uses a neighbor cell LTE measurement indication signaling (MeasObjectEUTRA) or an uplink 7.5kHz frequency offset indication signaling (frequency shift7p5 kHz) to implicitly instruct the NR terminal to turn on the neighbor cell CRS interference suppression function.
Specifically, for a terminal that only supports capability 6 and/or capability 8 in capability 5, capability 6, capability 7 and capability 8, the base station may use neighbor cell LTE measurement indication signaling defined in TS38.331, or uplink 7.5kHz frequency offset indication signaling, to implicitly indicate that the terminal simultaneously starts a neighbor cell CRS interference suppression function.
In an exemplary embodiment, the NR base station instructs the NR terminal to turn on or off the neighbor CRS interference suppression function when the present cell receives downlink data through the target RRC signaling display.
Specifically, the base station may explicitly instruct the terminal to turn on or off the neighboring CRS interference suppression function when the terminal receives downlink data in the cell through target RRC (Radio Resource Control ) signaling. The target RRC signaling may be an additional RRC signaling different from the LTE-CRS-to-match around signaling, the neighbor cell LTE measurement indication signaling, and the uplink 7.5kHz frequency offset indication signaling.
The above RRC signaling may be defined in the TS 38.214 and TS38.331 standards.

In the embodiment of the present disclosure, if the plurality of interference suppression capabilities include at least one of the first interference suppression capability and the third interference suppression capability in the first interference suppression capability, the second interference suppression capability, the third interference suppression capability and the fourth interference suppression capability, the NR terminal in the first interference scenario automatically turns on or off the neighboring cell CRS interference suppression function according to the neighboring cell interference condition; and if the plurality of interference suppression capabilities include at least one of the fifth interference suppression capability and the seventh interference suppression capability in the fifth interference suppression capability, the sixth interference suppression capability, the seventh interference suppression capability and the eighth interference suppression capability, the NR terminal in the second interference scene automatically starts or closes the adjacent cell CRS interference suppression function according to the adjacent cell interference condition.
That is, for the terminal with capability 1/3/5/7 (and/or relation) reported in the above-mentioned capability 1-8, the base station may optionally instruct the terminal to turn on or off the neighboring cell CRS interference suppression function through the above-mentioned RRC signaling; the terminal can also automatically start or close the adjacent cell CRS interference suppression function according to the adjacent cell interference condition.
In the embodiment of the disclosure, the base station instructs the terminal to turn on or off the neighboring cell CRS interference suppression function, so that the terminal does not need to frequently detect neighboring cell signals, thereby saving the detection energy consumption of the terminal.
Specifically, for the terminal with the supporting capability 1/2/5/7 reported in the above capability 1 to capability 8, the base station instructs the terminal to turn on or off the neighboring cell CRS interference suppression function in one of the following ways.
In an exemplary embodiment, if the plurality of interference suppression capabilities include the first interference suppression capability and/or the third interference suppression capability in the first interference suppression capability, the second interference suppression capability, the third interference suppression capability and the fourth interference suppression capability, the NR base station in the first interference scenario uses LTE CRS rate matching signaling of the terminal to implicitly instruct the NR terminal to turn on the neighbor CRS interference suppression function.
Specifically, for a terminal that reports support capability 1 and/or capability 3 in capability 1, capability 2, capability 3 and capability 4, the base station may implicitly instruct the terminal to simultaneously start the neighbor CRS interference suppression function by using LTE-CRS-to-matching signaling defined in TS 38.331.
In an exemplary embodiment, if the several interference suppression capabilities include the fifth interference suppression capability and/or the seventh interference suppression capability in the fifth interference suppression capability, the sixth interference suppression capability, the seventh interference suppression capability and the eighth interference suppression capability, the NR base station in the second interference scenario uses the neighbor cell LTE measurement signaling or the uplink 7.5kHz frequency offset indication signaling to implicitly instruct the NR terminal to turn on the neighbor cell CRS interference suppression function.

Fig. 5 is a flowchart illustrating another information transmission method according to an exemplary embodiment.
As shown in fig. 5, the information transmission method provided in the embodiment of the present disclosure may include step S502 on the basis of fig. 1.
In step S502, if the plurality of interference suppression capabilities include at least one of the first interference suppression capability, the third interference suppression capability, the fifth interference suppression capability, and the seventh interference suppression capability, the NR base station sends a list including N arrays to the NR terminal through RRC signaling, where N is an integer greater than or equal to 1, and each array in the list is used to indicate neighbor cell CRS information possibly overlapping with the own cell of the NR terminal.
In the embodiment of the disclosure, for the terminal with reporting support capability of 1/3/5/7, the base station may optionally indicate the CRS information of the neighbor cell through the above RRC signaling, so that the terminal does not need to perform neighbor cell signal detection frequently.
The information included in the list in the embodiment shown in fig. 5 may be the same as the information included in the list in the embodiment shown in fig. 4, and in particular, reference may be made to the text description of the embodiment shown in fig. 4, which is not repeated herein.
In the embodiment of the disclosure, for example, in an NR LTE coexistence scenario, the system bandwidth of the present cell 5G is B1, the system bandwidth of the neighboring cell a is B2, the system bandwidth of the neighboring cell B is B3, where the frequency domain overlapping portion of B1 and B2 is B12, and the frequency domain overlapping portion of B1 and B3 is B13.
For example, it is known at the 5G NR network side that, for a 5G terminal accessing a serving cell, a base station will initiate a capability query to the terminal, and the terminal reports the CRS interference suppression capability of the terminal neighboring cell to the base station, i.e. whether the terminal supports one or more of the "capability 1 to capability 10" described above.
For example, the terminal M only reports supporting capability 2 and/or capability 4, and the base station may use LTE-CRS-to-matcharound signaling to implicitly instruct the terminal M to turn on the neighbor CRS interference suppression function.
For example, the terminal M only reports the supporting capability 6 and/or the capability 8, and the base station may use the neighbor cell LTE measurement indication signaling, or the uplink 7.5kHz frequency offset indication signaling, to implicitly instruct the terminal M to turn on the neighbor cell CRS interference suppression function.
For example, the terminal M only reports at least one of supporting capability 2, capability 4, capability 6 or capability 8, and the base station may explicitly instruct the terminal M to turn on or off the CRS interference suppression function of the neighboring cell when the terminal M receives the downlink data in the cell through the target RRC signaling.
For example, the terminal M reports support capability 1 and/or capability 3, and the base station may optionally use LTE-CRS-to-match around signaling to implicitly instruct the terminal M to turn on the neighbor CRS interference suppression function.
For example, the terminal M only reports supporting capability 5 and/or capability 7, and the base station may optionally use neighboring cell LTE measurement indication signaling, or uplink 7.5kHz frequency offset indication signaling, to implicitly instruct the terminal M to turn on the neighboring cell CRS interference suppression function.
For example, the terminal M only reports at least one of supporting capability 1, capability 3, capability 5 or capability 7, and the base station may optionally explicitly instruct the terminal M to turn on or off the CRS interference suppression function of the neighboring cell when the terminal M receives the downlink data in the cell through the target RRC signaling.
In addition, the base station can also directly send the neighbor cell CRS configuration information to the terminal through RRC signaling, instruct the terminal M to perform CRS interference suppression at the corresponding position.
According to the information transmission method provided by the embodiment of the disclosure, the NR base station can receive the LTE neighbor cell CRS interference suppression capability under the multi-interference scene supported by the NR terminal and reported by the NR terminal, and the NR base station can instruct the NR terminal to start or close the interference suppression function according to the interference suppression capability reported by the NR terminal. The method can assist the NR terminal to perform interference suppression under the NR LTE coexistence scene, and the reliability of the terminal for receiving the downlink data is improved to a greater extent.
In addition, the network side can optionally inform the terminal of the information such as the frequency domain position and/or the interference signal sequence when the 4G CRS interferes with the source cell, so as to assist the terminal in interference detection and suppression, and improve the receiving reliability of the 5G terminal in a DSS scene while saving the detection energy consumption of the terminal.
