The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless expressly specified otherwise.
Some communication terms or nouns referred to in this application are explained below.
1. Beam (beam)
The beam's implementation in the New Radio (NR) protocol may be referred to as spatial filter (spatial domainfilter), spatial filter (spatial filter) or spatial parameter (spatial parameter). The beam used to transmit the signal may be referred to as a transmit beam (transmission beam, tx beam), spatial transmit filter (spatial domain transmission filter), or spatial transmit parameters (spatial transmissionparameter); the beam used to receive the signal may be referred to as a receive beam (Rx beam), a spatial receive filter (spatial domain receive filter), or spatial receive parameters (spatial RXparameter).
The transmit beam may refer to a distribution of signal strengths formed in spatially different directions after signals are transmitted through the antennas, and the receive beam may refer to a distribution of signal strengths of wireless signals received from the antennas in spatially different directions.
It should be understood that the above listed NR protocols are examples only for the implementation of beams and should not constitute any limitation to the present application. The present application does not exclude the possibility of defining other terms in future protocols to represent the same or similar meanings.
Furthermore, the beam may be a wide beam, or a narrow beam, or other type of beam. The technique of forming the beam may be a beamforming technique or other technique. The beamforming technique may specifically be a digital beamforming technique, an analog beamforming technique, or a hybrid digital/analog beamforming technique, etc. Different beams may be considered different resources. The same information or different information may be transmitted through different beams.
Alternatively, a plurality of beams having the same or similar communication characteristics are regarded as one beam. One or more antenna ports may be included in a beam for transmitting data channels, control channels, and sounding signals, etc. One or more antenna ports forming a beam may also be considered as a set of antenna ports.
In the embodiment of the present application, if no specific description is made, the beam refers to a transmission beam of the network device. In beam measurement, each beam of the network device corresponds to a resource, and thus the beam to which the resource corresponds can be uniquely identified by an index of the resource.
2. Channel information
The channel information may include one or more of the following: beam quality, channel quality indication (channel quality indicator, CQI), precoding matrix indicator (precoding matrix indicator, PMI), layer Indicator (LI), rank Indicator (RI), delay spread (delay spread), doppler spread (doppler spread), doppler shift (doppler shift), average delay (average delay), average gain, spatial reception parameters (spatial Rx parameters).
The beam quality may be one of the following: reference signal received power (reference signal receiving power, RSRP), reference signal received quality (reference signal receiving quality, RSRQ), or signal to interference plus noise ratio (signal to interference plus noise ratio, SINR).
The spatial reception parameters may include one or more of the following: angle of arrival (AOA), average AOA, AOA spread, angle of departure (angle of departure, AOD), average angle of departure AOD, AOD spread, receive antenna spatial correlation parameter, transmit antenna spatial correlation parameter.
Optionally, in the embodiment of the present application, the object to be reported by using absolute value quantization is not limited to the beam quality in the channel information, but may be other information except the beam quality in the channel information, and in the embodiment of the present application, the object to be reported by using differential quantization is not limited to the beam quality, but may be other information except the beam quality in the channel information, which is not limited herein.
3. Beam quality information
The beam quality information is quantitatively determined for the beam quality. For example, for reference signal received power (reference signal receiving power, RSRP), if the terminal device only needs to report the RSRP of one reference signal, or for the largest one of the RSRP of multiple reference signals reported by the terminal device, the beam quality information is determined by quantization of the RSRP. For other RSRPs than the maximum RSRP among the RSRPs of the plurality of reference signals reported by the terminal device, the beam quality information is determined by quantizing the differential RSRP, where the differential RSRP may be, for example, a difference between the maximum RSRP and the RSRP other than the maximum RSRP.
4. Absolute value quantization and differential quantization
Absolute value quantization, i.e. quantifying the measured value. For example, according to the 3GPP standard protocol TS 38.133 v16.1.0 table 10.1.6.1-1, if the RSRP measured value is-100 dBm, the beam quality information corresponding to the quantized result is RSRP_57, and if the RSRP is reported using 7 bits according to the requirement of the 3GPP standard protocol TS 38.214 v16.2.0, 0111001 is obtained.
Differential quantization, i.e. the quantization of the difference between two measured values. For example, if the two beam qualities are-105.5 dBm and-100 dBm, respectively, with the maximum value of-100 dBm as a reference, the differential RSRP corresponding to-105.5 dBm is-5.5 dB, that is, the difference between-105.5 dBm and-100 dBm, and the terminal device quantizes the differential RSRP of-5.5 dB according to the 3GPP standard protocol TS 38.133 v16.1.0 table 10.1.6.1-2, and then the quantized result thereof corresponds to the beam quality information of diffrsrp_2. If 4 bits are used to report the differential RSRP according to the requirement of the 3GPP standard protocol TS 38.214 v16.2.0, 0010 is obtained.
The foregoing briefly describes the meanings of some nouns (or terms) according to the embodiments of the present application, and in order to better understand the channel information reporting method provided by the embodiments of the present application, the system architecture and/or the application scenario of the channel information reporting method provided by the embodiments of the present application will be described below. It can be understood that the scenario described in the embodiments of the present application is for more clearly describing the technical solutions of the embodiments of the present application, and does not constitute a limitation on the technical solutions provided by the embodiments of the present application.
To facilitate an understanding of the present application, related art knowledge related to embodiments of the present application is described herein.
In general, the access network device may send configuration information to the terminal device, including resource configuration information and reporting configuration information. The resource configuration information comprises one or more resource sets, each resource set comprises one or more downlink signal resources, and each downlink signal resource corresponds to one wave beam. The downlink signal includes: channel state information reference signals (channel state informationreference signal, CSI-RS), cell specific reference signals (cell specific reference signal, CS-RS), UE specific reference signals (user equipment specific reference signal, US-RS), demodulation reference signals (demodulation reference signal, DMRS), and synchronization signals/physical broadcast channel blocks (synchronization signal/physical broadcast channel block, SS/PBCH block). Wherein SS/PBCH block may be simply referred to as a synchronization signal block (synchronization signal block, SSB). Reporting the configuration information includes at least one of: the resource identification of the downlink signal to be reported by the terminal equipment, the number of beam quality to be reported by the terminal equipment, and the like. In addition, the reporting configuration information further includes an identifier of the resource configuration information to instruct the terminal device to measure the reference signal based on which resource configured by the resource configuration information.
Further, the access network device may send one or more reference signals to the terminal device via one or more transmit beams. The terminal device receives one or more reference signals over one or more receive beams. And measuring one or more reference signals received by the terminal equipment to obtain one or more beam quality. The terminal device may then report the beam quality. In one possible manner, the terminal device may report according to the configuration information, for example, the beam quality is reported according to the number of beam qualities that the terminal device needs to report. Finally, the access network device can select a beam suitable for data transmission according to the beam quality and the scheduling policy reported by the terminal device and indicate the beam to the terminal device.
It should be noted that, in one implementation manner, the terminal device may report all or part of all the measured beam qualities to the access network device according to the configuration of the access network device, for example, the terminal device measures 3 beam qualities, and then the terminal device reports the 2 beam qualities to the access network device. In another implementation manner, the terminal device may report beam quality greater than a threshold value in the measured beam qualities to the access network device, for example, the terminal device measures 3 beam qualities, where 2 beam qualities are greater than the threshold value, and the terminal device reports the 2 beam qualities to the access network device.
Secondly, when the number of the reported beam quality is greater than 1, the terminal equipment can take the beam quality with the best quality as a reference value, and quantize the rest beam quality except the reference value by adopting differential quantization and report.
Further, the terminal device may refer to different bit widths when reporting the quantized beam quality. For example, referring to table 1, in table 1, the bit width (bit width) corresponding to RSRP (RSRP with best quality) is 7, and the bit width corresponding to differential RSRP (differential RSRP) is 4, that is, the bit width corresponding to RSRP requiring differential reporting is 4. It will be appreciated that the specific values of the bit widths are not limiting in this application.
Table 1: bit width involved in reporting beam quality
| Field (field) | Bit width |
| RSRP | 7 |
| differential RSRP | 4 |
It will be appreciated that for the best quality beam quality, the terminal device uses absolute value quantization to report using 7 bits. If the best quality RSRP is-100 dBm, in combination with table 3, it can be determined that the beam quality information corresponding to-100 dBm is rsrp_57, and rsrp_57 is represented by a binary bit as 0111001. In addition, for the best beam quality, the corresponding quantization step is 1dB. For the beam qualities other than the beam quality with the best quality, the terminal device may quantize according to the difference between each beam quality in the other beam qualities and the beam quality with the best quality, that is, differentially quantize each beam quality in the other beam qualities to report using 4 bits. For example, the best quality RSRP1 is-100 dBm, RSRP2 is-105.5 dBm, and RSRP3 is-110 dBm. Then the difference between RSRP2 and RSRP1 is-5.5 dB and the difference between RSRP3 and RSRP1 is-11 dB. Further, referring to table 2, in table 2, the quantization range corresponding to diffrsrp_1 is: -2 is greater than or equal to DeltaRSRP > -4; the quantization range corresponding to diffrsrp_2 is: -4 is greater than or equal to DeltaRSRP > -6; the quantization range corresponding to diffrsrp_3 is: -6 is greater than or equal to DeltaRSRP > -8; the quantization range corresponding to diffrsrp_4 is: -8 is greater than or equal to DeltaRSRP > -10; the quantization range corresponding to diffrsrp_5 is: -10 > ΔRSRP > -12. I.e. the quantization step sizes are all 2dB. It can be seen by combining Table 2 that the quantization range within which-5.5 dB falls is-4. Gtoreq.DELTA.RSRP > -6, i.e., the beam quality information corresponding to RSRP2 is DIFFRSRP_2, and DIFFRSRP_2 is represented as 0010 in binary bits; the quantization range within which-11 dB falls is-10 ≡DeltaRSRP > -12, namely, the beam quality information corresponding to RSRP2 is DIFFRSRP_5, and DIFFRSRP_5 is represented as 0101 by binary bits.
Table 2: correspondence between reported values and quantized ranges (intercepted from standard protocol TS38.133 table)
In summary, it can be seen that the quantization process of beam quality is related to the quantization step size. For example, the best beam quality is-80 dBm, one of the other beam qualities is-84.1 dBm, and the other beam quality is-85.9 dBm. Then the difference between-84.1 dBm and-80 dBm is-4.1 dBm, the difference between-84.1 dBm and-85.9 dBm is-5.9 dB, and by combining with Table 2, it can be seen that the quantization ranges of-4.1 dB and-5.9 dB are-4.gtoreq.ΔRSRP > -6, i.e. DIFFRSRP_2 is reported by the terminal equipment to the access network equipment. Meanwhile, when the access network equipment analyzes DIFFRSRP_2 according to the quantization step length and the best beam quality, the access network equipment can determine that the corresponding DIFFRSRP_2 is-84 dBm to-86 dBm for-84.1 dBm and-85.9 dBm because-4 which corresponds to DIFFRSRP_2 is more than or equal to delta RSRP > -6. And-86 dBm and-84.1 dBm by 1.9dB, -84dBm and-85.9 dBm by 1.9dB. It can be seen that for one beam quality, the terminal device can approach a maximum of 2dB error at quantization or at resolution of the access network device. Therefore, how to reduce quantization error is a problem to be solved.
Based on this, the embodiment of the present application proposes a channel information reporting method to solve the above problem, and the following details of the embodiment of the present application are described.

Alternatively, the terminal device may randomly select the quantization mode, and this method is more consistent with the random dithering noise principle. For example, the terminal device quantizes the first beam quality at least twice according to at least two quantization modes, and determines at least two beam quality information, including: the terminal equipment quantifies the first beam quality in a first quantification mode according to the first probability determination to obtain first beam quality information in at least two beam quality information; and the terminal equipment quantifies the first beam quality in a second quantification mode according to the second probability determination, so as to obtain second beam quality information in at least two beam quality information. The first probability and the second probability may be the same or different, and the specific sizes of the first probability and the second probability are not limited herein. It will be appreciated that in this application, the first probability may also be referred to as an offset probability, although the offset probability is merely a name, and is not limited by this application.

For example, if the first beam quality is the beam quality that needs to be quantized and reported by adopting an absolute value, the third preset offset is 0.5dB, referring to table 4 and table 5, it can be seen that if the first reported value and the second reported value are rsrp_57, the first quantization range is-100 < RSRP < -99, and the second quantization range is-100+0.5 < RSRP < -99+0.5, that is, -99.5 < RSRP < -98.5; if the first reporting value and the second reporting value are both RSRP_58, the first quantization range is-99.ltoreq.RSRP < -98, and the second quantization range is-99+0.5.ltoreq.RSRP < -98+0.5, that is-98.5.ltoreq.RSRP < -97.5.

For example, if the first beam quality is the beam quality that needs to be reported using differential quantization, if the fourth preset offset is 1dB, referring to Table 6 and Table 7, it can be seen that if the third reporting value and the fourth reporting value are DIFFRSRP_1, the third quantization range is-2 ΔRSRP > -4, the fourth quantization range-2+1 ΔRSRP > -4+1, i.e., -1 ΔRSRP > -3; if the third reporting value and the fourth reporting value are DIFFRSRP_2, the third quantization range is-4 equal to or greater than DeltaRSRP > -6, and the fourth quantization range is-4+1 equal to or greater than DeltaRSRP > -6+1, namely-3 equal to or greater than DeltaRSRP > -5.

As another example, for SINR, the first quantization accuracy is 0.5dB; for differential SINR, the first quantization accuracy is 1dB.

Further, for example, -100.ltoreq.RSRP < -99.5, the difference between the maximum and minimum is 0.5, i.e. the quantization accuracy supported by the terminal device is 0.5dB.
Table 8: fifth mapping relation
| A plurality of fifth measured values | Multiple fifth quantization ranges | Unit (unit) |

Optionally, if the access network device determines the third beam quality information according to an average value or a weighted average value of at least two beam quality information, a quantization range corresponding to the third beam quality information is a quantization range corresponding to the measurement value a in the fifth mapping relationship or a quantization range corresponding to the measurement value B in the sixth mapping relationship. Wherein the third beam quality information is the same as the measurement value a, or the third beam quality information is closest to the measurement value a; the third beam quality information is the same as, or closest to, measurement B.
For example, referring to table 9, it can be seen that, when the beam quality information reported by the access network device for the 1 st time by the terminal device is 0111001, that is, rsrp_57, and the beam quality information reported by the access network device for the 2 nd time by the terminal device is 0111010, that is, rsrp_58, the access network device can determine rsrp_57.5 according to the average value of rsrp_57 and rsrp_58. By combining Table 8, it can be seen that the corresponding quantization range is-99.5.ltoreq.RSRP < -99.
Table 9: twice reported beam quality information and average value thereof
| Report 1 st time | Report 2 | Mean value of |
| 0111001 | 0111010 | RSRP_57.5 |
For example, if the beam quality information reported by the access network device receiving terminal device 1 st time is 0111001, i.e. rsrp_57, the beam quality information reported by the access network device receiving terminal device 2 nd time is 0111010, i.e. rsrp_58, and the beam quality information reported by the access network device receiving terminal device 3 rd time is 0111001, i.e. rsrp_57. Then, the average value of rsrp_57, rsrp_58, and rsrp_57 is rsrp_57.3. In combination with Table 8, it can be seen that RSRP_57.3 is closest to RSRP_57.5. Therefore, when the access network device determines the quantization range of the RSRP_57.3, the quantization range corresponding to the RSRP_57.5 can be used as the quantization range corresponding to the RSRP_57.3, namely, the quantization range corresponding to the RSRP_57.3 is-99.5.ltoreq.RSRP < -99.

Optionally, if the access network device determines the fourth beam quality information according to an average value or a weighted average value of at least two beam quality information, the quantization range corresponding to the fourth beam quality information is the quantization range corresponding to the measurement value C in the seventh mapping relationship or the quantization range corresponding to the measurement value D in the eighth mapping relationship. Wherein the fourth beam quality information is the same as the measurement value C, or the fourth beam quality information is closest to the measurement value C; the fourth beam quality information is the same as or closest to the measurement value D.
For example, referring to table 11, it may be seen that, when the access network device receives the first report of the beam quality information of the terminal device 1 and is 0010, that is, diffrsrp_2, and the access network device receives the second report of the beam quality information of the terminal device 2 and is 0011, that is, diffrsrp_3, the access network device may determine diffrsrp_2.5 according to the average value of diffrsrp_2 and diffrsrp_3. As can be seen by combining Table 10, the corresponding quantization range is-5.gtoreq.ΔRSRP > -6.
Table 11: twice reported beam quality information and average value thereof
| Report 1 st time | Report 2 | Mean value of |
| 0010 | 0011 | DIFFRSRP_2.5 |
It can be understood that, the beam quality information reported by the access network device for the 1 st time by the receiving terminal device is 0010, i.e. diffrsrp_2, the beam quality information reported by the access network device for the 2 nd time by the receiving terminal device is 0011, i.e. diffrsrp_3, and the beam quality information reported by the access network device for the 3 rd time by the receiving terminal device is 0010, i.e. diffrsrp_2, then the average value of diffrsrp_2, diffrsrp_3 and diffrsrp_2 is diffrsrp_2.3. In combination with table 10, it can be seen that diffrsrp_2.3 is closest to diffrsrp_2.5, and therefore, when the access network device determines the quantization range of diffrsrp_2.3, the quantization range corresponding to diffrsrp_2.5 can be used as the quantization range corresponding to diffrsrp_2.3, i.e. the quantization range corresponding to diffrsrp_2.3 is-5+.DELTA.rsrp > -6.

That is, in the present application, the quantization accuracy is improved from 2dB to 1dB, i.e., the quantization accuracy is improved by 2 times.
