Technical field

The present disclosure relates to the field of communications technologies, and in particular, to a channel state information transmission method, a communication device, and a device.

Background technique

In the LTE radio communication system, the aperiodic CSI (Channel State Information) is transmitted through the physical uplink shared channel (PUSCH), and the base station eNodeB triggers the terminal UE to perform the reporting of the aperiodic CSI by scheduling the downlink control information DCI of the uplink data. In the downlink control information DCI for scheduling the uplink data, an information field in the village is used to trigger the aperiodic CSI reporting. When the information field indicates that the terminal needs to report the aperiodic CSI, the terminal performs the aperiodic CSI reporting on the PUSCH in the predefined location.

In the LTE system, the RI (rank indication) and the CQI (Channel Quality Indicator)/PMI (Precoding Matrix Indicator) are independently coded. When the PUSCH does not contain data only When the transmission of control information is included, the RI is mapped to data symbols #1, #4, #7, #10 (under normal cyclic prefix conditions) or symbol #0 other than DMRS (Demodulation Reference Signal). #3,#5,#8(Under extended cyclic prefix conditions), the number of REs (Resource Element) that are specifically occupied is determined according to the following formula:

Wherein, O is the number of RI bits; O _CQI-MIN is the number of CQI bits including CRC (Cyclic Redundancy Check). When determining O _CQI-MIN , all RIs of the serving cell that triggers aperiodic reporting are assumed. Is 1;

Is the scheduling bandwidth of the PUSCH in the current subframe represented by the subcarrier;

Is the number of scheduling symbols of the PUSCH in the current subframe;

Is the code rate offset value of RI relative to CQI. In addition to the resources occupied by the RI, the remaining resources in the PUSCH are used to transmit CQI/PMI information.

As the demand for mobile communication services changes, organizations such as the ITU (International Telecommunication Union) and 3GPP have begun to research new wireless communication systems (for example, 5G NR, 5 Generation New RAT). Currently, in a 5G NR (air interface), the aperiodic CSI transmitted on the PUSCH may also include two parts, where the first part CSI includes the RI and the first part of the CQI/PMI information, and the second part of the CSI includes the remaining CQI/PMI information. The first part of the CSI and the second part of the CSI are independently coded and mapped.

Since the content of the two parts of CSI in NR is different from that in LTE, on the other hand, the design of DMRS is different from that in LTE, and the number and location of symbols occupied by DMRS are not fixed, so CSI in LTE cannot be reused. Resource mapping mechanism. Therefore, in the NR, for the CSI transmitted on the PUSCH, when the uplink shared channel UL-SCH data transmission is not included in the PUSCH, there is no specific method for determining how to use each part of the CSI for transmission on the PUSCH.

Manner 3: pre-defining a set of code rates that can be used by the first part of the CSI in the protocol; receiving downlink control information that can trigger the terminal to send the first part of CSI, and determining, according to the indication information of the specific indication field in the downlink control information, One code rate in the set of code rates is used as a target code rate of the first partial CSI; the code rate set includes two or more code rates.

In this manner, a set of code rates is predefined in a protocol or a standard, and the code rate set also includes two or more code rates, and the first partial CSI may use any one of the code rate sets as the first The target bit rate used by some CSIs. The specific first rate of the CSI is used as the target code rate, which can be indicated by the specific indication field of the downlink control information DCI, which is a DCI capable of triggering the terminal to send the first partial CSI.

It should be noted that, in the third manner, the specific indication field in the downlink control information is: a hybrid automatic repeat request HARQ process number indication information field;

The indication information of the HARQ process number indication information field is used to indicate a code rate associated with the modulation order of the first partial CSI in the protocol preset table. The default form of the above agreement is: Table 6.1.4.1-1 of 3GPP Protocol 38.213. That is, the hybrid automatic retransmission request HARQ process number indication information field indicates the code rate corresponding to the modulation order of the first partial CSI described in Table 6.1.4.1-1 of the 3GPP protocol 38.213.

Preferably, in a case where the modulation order of the first partial CSI is 2, the high three-bit information or the low three-bit information of the HARQ process number indication information field is used to indicate the modulation and the modulation in the protocol preset table. 8 code rates with an order of 2;

It should be further noted that, when the first part of the CSI specifically uses the code rate of the first set of CSI as the target code rate of the first partial CSI by using the downlink control information DCI or the high layer signaling of the base station, the downlink control information DCI is used. The indication information of the specific indication domain or the indication information in the high layer signaling may directly indicate a certain code rate in the code rate set or indirectly indicate the code rate by indicating a certain code rate sequence number in the code rate set. For example, the code rate set is {0.08, 0.15, 0.25, 0.35, 0.45, 0.60, 0.80}, and the indication information may directly indicate that the target code rate of the first partial CSI is 0.15, or the indication information may indicate the target bit rate of the first partial CSI. The second value in the set of code rates indirectly indicates that the target code rate is 0.15.

Preferably, the determining, according to the target code rate used by the first partial CSI, the information bit number of the first partial CSI, and the modulation order of the first partial CSI, determining resource elements available on the PUSCH for the first partial CSI transmission The number of steps for RE, including:

among them,

It should be noted that if the number of resource units RE available for the first partial CSI transmission on the PUSCH is greater than the number of resource units RE available for the uplink control information UCI transmission on the PUSCH, the PUSCH can be used for the uplink control information UCI. The transmitted resource elements RE are each determined to be resource elements RE available for the first partial CSI transmission, and it is determined that there are no resource elements RE available for the second partial CSI transmission on the PUSCH.

The number of REs available for UCI transmission on the PUSCH is set to the upper limit of the number of resource units available for the first partial CSI transmission, when the calculated number of REs available for the first partial CSI transmission is greater than the RE available for UCI transmission on the PUSCH The number of REs available for the first partial CSI transmission in this transmission is equal to the number of REs available for UCI transmission on the PUSCH.

The actual code rate corresponding to the second part of the CSI specifically refers to the actual code rate corresponding to the total number of bits included in the second part of the CSI. For example, the second partial CSI uses QPSK modulation, and the second partial CSI includes 60 bits in total, and the corresponding actual code rate is 60/(50*2)=0.6.

In summary, in the foregoing embodiment of the present disclosure, the resource used for transmitting the second part of the CSI may be smaller than the actual resource that the second part of the CSI needs to occupy. In this case, the second part of the CSI may not be used for the second transmission. Part of the CSI is transmitted over the resource, at which point it is necessary to determine the number of bits of the second partial CSI that it can transmit on the resources available for the second partial CSI transmission, thereby ensuring that the resources available for the second partial CSI transmission are correct. A portion of the bits of the second portion of the CSI are transmitted.

For example, a resource available for the second partial CSI transmission on the PUCSCH includes a total of 50 REs; the second partial CSI uses QPSK (Quadrature Phase Shift Keyin) modulation, and the second partial CSI code The rate threshold is 0.4.

If the second partial CSI includes a total of 60 bits, the corresponding actual code rate is 60/(50*2)=0.6, which is greater than the code rate threshold of the second partial CSI by 0.4, according to the second part of the CSI. The discarding rule discards 30 bits, and the remaining 30 bits of the second part of the CSI, and recalculates the actual code rate corresponding to the remaining second part of the CSI by 30/(50*2)=0.3, which is smaller than the code of the second part of the CSI. The rate threshold is 0.4, and the second partial CSI of 30 bits is transmitted on the resource transmitted by the second part of the CSI.

In order to more clearly describe the embodiment of the present disclosure, a channel state information CSI transmission method is provided, which will be specifically described below in conjunction with two examples.

Example one

It is assumed that the base station indicates through the DCI that the PUSCH does not contain data transmission, and only includes transmission of aperiodic CSI. The aperiodic CSI is divided into a first partial CSI and a second partial CSI; wherein the first partial CSI includes 50 bits and the second partial CSI includes 100 bits. When the base station allocates 14 OFDM symbols and 2 RB resources to the current PUSCH transmission, if the DMRS occupies the first OFDM symbol, the number of RE resources available for UCI transmission is 13*12*2=312.

First, the target bit rate used by the first part of the CSI is obtained.

Manner 1: The target code rate used by the base station to directly configure the first part of the CSI is 0.15.

Manner 2: The base station configures the first part of the CSI to use a set of code rates of {[0.08, 0.15, 0.25, 0.35, 0.45, 0.60, 0.80]}, and then indicates, by DCI, that the first part of the CSI uses a target code rate of 0.15.

Manner 3: The set of code rate values used by the first part of the CSI is defined as {[0.08, 0.15, 0.25, 0.35, 0.45, 0.60, 0.80]}, and the base station indicates, by the high layer signaling, that the first part of the CSI uses the target bit rate. The second value is 0.15.

Manner 4: The base station may indicate the modulation order of the first partial CSI and the target code rate used by using the MCS information field in the DCI. For example, a column of target code rate is added to the MCS table defined in the standard as the target bit rate used by the first partial CSI. As shown in Table 1, only the I _MCS 3 to 23 in the table indicates the modulation order of the first partial CSI. And target bit rate.

Table 1 MCS indication of PUSCH

Manner 5: The base station may indicate the target code of the first part of the CSI through the MCS information field in the DCI (excluding one or more combinations of using other information fields (eg, HARQ process indication information field, RV indication field, NDI indication field)) Rate and / or modulation order. For example, using the target code rate in the MCS table defined in the standard as the target code rate used for the first partial CSI, as shown in Table 2, the target code rate of the first partial CSI is indicated using I _{MCS 0-27} in the table and / Or modulation order, MCS information field in DCI (does not exclude using one or more combinations of other information fields (such as HARQ process indication information field, RV indication field, NDI indication field)) to indicate which MCS in the table is used. index.

Manner 6: The base station obtains the modulation order of the first part of the CSI through the MCS information field and the NDI information field and/or the RV information field, and indicates the information in the protocol preset table by using the HARQ process in the downlink control information DCI. The code rate associated with the modulation order of a portion of the CSI. The above preset form of the agreement is: Table 6.1.4.1-1 of 3GPP protocol 38.213. For example, Table 2 is Table 6.1.4.1-1 of the 3GPP protocol 38.213. When the modulation order of the first partial CSI is 2, the high three or lower three bits of the 4 bits of the information field are indicated by the HARQ process number to indicate The code rate corresponding to the I _MCS 2 to 9 in the table; when the modulation order of the CSI is 4, the upper three bits or the lower three bits of the 4 bits of the information field are indicated by the HARQ process number to indicate the I _MCS in the table. The code rate corresponding to 10 to 16; when the modulation order of the CSI is 6, the 4-bit information of the information field of the HARQ process number is used to indicate the code rate corresponding to the I _MCS 18 to 27 in the table.

In this example, the first partial CSI includes 50 bits, and if the first partial CSI uses QPSK (Quadrature Phase Shift Keyin) modulation, and the target code rate is 0.15, then

Then 167 RE resources in the PUSCH can be used to transmit the first partial CSI. As shown in Figure 2, the identifier is

RE resource for DMRS transmission, identified as

RE resources are available for the transmission of the first part of the CSI. RE resources that can be used for the second part of CSI transmission

As shown in Figure 2, the identifier is

The RE resources can be used for the transmission of the second part of the CSI.

Example two

It is assumed that the base station indicates through the DCI that the PUSCH does not contain data transmission, and only includes transmission of aperiodic CSI. The aperiodic CSI is divided into a first partial CSI and a second partial CSI; wherein the first partial CSI includes 50 bits and the second partial CSI includes 100 bits. When the base station allocates 14 OFDM symbols and 1 RB resource to the current PUSCH transmission, if the DMRS occupies the first OFDM symbol, the number of RE resources available for UCI transmission is 13*12=156.

It is assumed that the corresponding target code rate in the MCS table (ie, Table 1) defined in the standard 38.214 is used as the target code rate of the first partial CSI. The base station indicates that the MCS corresponding to the CSI transmission is 0 in the DCI, and the corresponding modulation order is 2, and the target code rate used by the first partial CSI is 120/1024.

In this example, the first partial CSI contains 50 bits, using QPSK modulation, then

In this case, since the number of REs occupied by the first partial CSI is 214, which is greater than the number 156 of REs available for UCI transmission in the PUSCH, the number of RE resources used by the first partial CSI in the current transmission is determined. It is equal to the number of RE resources available for UCI transmission in the PUSCH. Correspondingly, there is no RE resource available for the second partial CSI transmission on the current PUSCH. In short, the first partial CSI is transmitted only on the current PUSCH, and all the second partial CSIs are discarded.

In summary, in the foregoing embodiment of the present disclosure, when two-part CSI is transmitted on the PUSCH and there is no data, resources available for the first partial CSI transmission on the PUSCH are determined according to the target code rate of the first partial CSI, and the remaining available on the PUSCH is determined. The resource is a resource that can be used for the second part of CSI transmission, so that the CSI information on the PUSCH in the 5G NR system can be correctly transmitted, thereby ensuring the performance of the NR system.
