- the number of network devices and terminal devices included in the communication system may also be other numbers.
- the UE sends UCI to the gNB through PUSCH
- the UE may miss the physical uplink control channel (PDCCH)
- the perception of the number of HARQ-ACK bits that needs to be fed back is wrong, that is, the actual feedback of the UE is
- the number of HARQ-ACK bits is less than the number of HARQ-ACK bits that the gNB schedules to feed back; in turn, all UCI sent by the UE through the PUSCH may not be correctly received by the gNB.
- the communication protocol defines a reserved RE (reserved RE for HARQ-ACK) for HARQ-ACK in the scenario where the UE sends UCI through PUSCH to gNB, that is, Reserve RE.
- RE reserved RE for HARQ-ACK
- the reserved RE is generated according to the number of HARQ-ACK information bits as 2.
- HARQ-ACK is sent on the reserved RE. At this time, it is equivalent to HARQ-ACK puncturing the CSI-part2 that has been mapped on the reserved RE.
- the PUSCH can be divided into two parts in the time domain.
- the two parts are called the first hop (hop1) and the second hop (hop2).
- the frequency domain resources of hop1 and hop2 are different.
- HARQ-ACK, CSI-part1 and CSI-part2 will also be mapped to hop1 and hop2 according to preset rules.
- mapping rules can be visually represented in Figure 2. As shown in Figure 2, CSI-part1 is only mapped to non-reserved REs; CSI-part2 is mapped to both reserved REs and non-reserved REs; if there is HARQ-ACK (information bit If it is 1 or 2), it is mapped to the reserved RE (equivalent to puncturing on the resource to which the coded bit of CSI-part2 has been mapped).
- HARQ-ACK information bit If it is 1 or 2
- the frequency hopping rules for the number of PUSCH symbols include frequency hopping within slots (slots) and frequency hopping between slots, specifically:
- the number of symbols in hop1 is half of the total number of PUSCH symbols and rounded down, namely
- the number of hop2 symbols is the total number of PUSCH symbols minus the number of hop1 symbols, that is among them It is the total number of PUSCH symbols in a slot.
- hop1 and hop2 are divided in time by slot. For example, if the slot number is an even number, it is hop1, and if the slot number is an odd number, it is hop2.
- the possible situations of frequency hopping in the slot include: the number of symbols that can carry data in hop1 and hop2 are equal; or, The number of data-carrying symbols of hop1 is 1 less than that of hop2; in the case of frequency hopping between slots, the number of data-carrying symbols of hop1 and hop2 is the same.
- the frequency hopping splitting rules for the number of coded bits mapped by the reserved RE are as follows:
- N L is the number of layers of PUSCH transmission
- Q m is a modulation order PUSCH. It can be seen from formula (1) and formula (2),
- Number of REs that can carry data on hop1 among them Is the number of symbols of hop1, As a collection Size, collection It is the number of REs that can carry data on l on the symbol.
- Number of REs that can carry data on hop2 among them Is the number of symbols of hop2.
- the number of REs that can carry data on PUSCH symbols after the first set of consecutive DMRS symbols on PUSCH hop1 The definition of 1 (1) is the first symbol index without DMRS after the first set of consecutive DMRS symbols; the set of consecutive DMRS symbols may include one DMRS symbol or multiple consecutive DMRS symbols.
- the coded bit frequency hopping split rules for each part of UCI are as follows.
- the number of HARQ-ACK coded bits is G ACK
- the number of HARQ-ACK coded bits sent on hop1 and hop2 are respectively:
- G ACK (2) G ACK -G ACK (1).
- G CSI-part1 (2) G CSI-part1 -G CSI-part1 (1) (6)
- G CSI-part2 (1) M 1 ⁇ N L ⁇ Q m -G CSI-part1 (1) (8)
- the number of coded bits of CSI-part1 is exactly equal to the number of coded bits mapped by all REs that can carry data on hop1 and hop2 of PUSCH except for reserved REs, namely
- G CSI-part2 (1)+G CSI-part2 (2) (M 1 +M 2 ) ⁇ N L ⁇ Q m -G CSI-part1 (14)
- the number of CSI-part1 coded bits on hop2 is greater than the number of coded bits mapped by the unreserved RE; and CSI-part1 cannot be carried by the reserved RE. Therefore, the transmission of CSI-part1 is incomplete.
- PUSCH is a single-carrier discrete Fourier transform spread orthogonal frequency division multiplexing (discrete Fourier transform spread orthogonal frequency division multiplexing, DFT-s-OFDM)
- DFT-s-OFDM discrete Fourier transform spread orthogonal frequency division multiplexing
- the above RE that does not transmit any data may destroy one or the other of hop2
- the uplink transmission of multiple symbols has a low peak-to-average power ratio (PAPR) characteristic of a single carrier.
- PAPR peak-to-average power ratio
- the symbol involved in this application is a time unit, and may be an orthogonal frequency-division multiplexing (OFDM) symbol.
- OFDM orthogonal frequency-division multiplexing
- this application provides a communication method that can solve the above-mentioned incomplete transmission of CSI-part1. In addition, it can also solve the above-mentioned problem that single carrier characteristics are destroyed when signals are sent on hop2 using DFT-s-OFDM waveforms. .
- the communication method includes:
- the downlink control information is used to schedule PUSCH.
- the PUSCH is only used to carry UCI.
- the PUSCH includes a first frequency hopping resource and a second frequency hopping resource. The time domain of the first frequency hopping resource starts The symbol is located before the time domain start symbol of the second frequency hopping resource.
- the first frequency hopping resource and the second frequency hopping resource are, for example, the aforementioned hop1 and hop2.
- the frequency domain resources of the first frequency hopping resource and the second frequency hopping resource are different, and the above difference means that the frequency domain resources of the first frequency hopping resource partially overlap with the frequency domain resources of the second frequency hopping resource, or No overlap at all.
- the time-frequency end position of the first frequency hopping resource is adjacent to the time domain start position of the second frequency hopping resource.
- the first frequency hopping resource is a continuous or discontinuous resource in the time domain
- the second frequency hopping resource is a continuous or discontinuous resource in the time domain. This explanation of frequency hopping resources can be applied to other methods or implementations in this application.
- the downlink control information described in S410 is, for example, downlink control information (DCI) transmitted through PDCCH.
- DCI downlink control information
- the base station can indicate whether the PUSCH is only used to transmit UCI through the different states of 1 bit in the DCI, that is, this one
- the different states of the bits are used to indicate whether the current communication scene is UCI-only.
- S420 Send a first UCI on the PUSCH, where the first UCI includes at least one of HARQ-ACK, CSI-part1, and CSI-part2;
- the number of coded bits mapped on the reserved RE in the first frequency hopping resource is the first value
- the number of coded bits mapped on the reserved RE in the second frequency hopping resource is the second value
- the first value is not less than the first value.
- Two values, the reserved RE in the first frequency hopping resource and the reserved RE in the second frequency hopping resource are REs reserved for potential HARQ-ACK transmission with the number of bits not greater than 2. "Potential HARQ-ACK transmission" is further explained here. In the embodiment of this application, HARQ-ACK may be transmitted on PUSCH or may not be actually transmitted. These reserved REs will be reserved regardless of transmission. These reserved REs correspond to a certain number of coded bits mapped on them.
- the number of HARQ-ACK bits involved in the "potential HARQ-ACK transmission" is not greater than 2, and when specifically calculating the number of mapped coded bits, the reserved RE will be calculated according to the number of HARQ-ACK bits equal to 2.
- the number of mapped coding bits When the embodiment of this application involves the number of coded bits mapped on the reserved RE, if there is no actual transmission, it can be understood as the number of coded bits that can be mapped on the reserved RE, or the corresponding number of coded bits. .
- the reason for the incomplete information transmission of CSI-part1 is that the number of coded bits mapped by CSI-part1 on the second frequency hopping resource is less, that is, the number of REs used to map CSI-part1 on the second frequency hopping resource is relatively large. As a result, CSI-part1 cannot be fully mapped to the second frequency hopping resource.
- the communication solution provided in this application reduces the number of coded bits that can be mapped by the reserved RE in the second frequency hopping resource, thereby increasing the number of The number of REs used to map CSI-part1 in the two frequency hopping resources solves the problem of incomplete information transmission in CSI-part1 caused by frequency hopping transmission of UCI in UCI-only scenarios.
- the method 400 solves the above-mentioned incomplete CSI-part1 transmission. While solving the problem shown in Figure 3.
- the “number of coded bits mapped by the reserved RE in the first frequency hopping resource is the first value
- the number of coded bits mapped by the reserved RE in the second frequency hopping resource is the second value
- the first value "Not less than the second value” refers to: reducing the number of reserved REs in the second frequency hopping resource to make the second value greater than or equal to the first value.
- the method 400 further includes:
- the “number of coded bits mapped on the reserved RE in the first frequency hopping resource and the reserved RE in the second frequency hopping resource” refers to the reserved RE and the second hop in the first frequency hopping resource.
- the sum of the number of coded bits that can be mapped by the reserved RE in the frequency resource should not be understood as the number of coded bits actually mapped by the reserved RE in the first frequency hopping resource and the reserved RE in the second frequency hopping resource.
- the first value is And/or, the second value is Wherein, N L is the number of layers of the PUSCH transmission, Q m is a modulation order of the first UCI, i.e., modulation order of the transmission of UCI on PUSCH.
- the method 400 further includes:
- G ACK of HARQ-ACK in the first UCI where the number of coded bits mapped by HARQ-ACK in the first UCI on the first frequency hopping resource is G ACK (1), G ACK (1)
- the value of is the smaller of the following two values:
- M 3 ⁇ N L ⁇ Q m represents the number of coded bits that can be used for data-carrying RE mapping after the symbols carrying the first group of consecutive DMRS on the first frequency hopping resource, or called the first frequency hopping The number of coded bits that can be used for data-bearing RE mapping after the first group of consecutive DMRS symbols on the resource, where the DMRS symbols are symbols used to carry DMRS.
- N L is the number of transmission layers of PUSCH
- Q m is a modulation order of the first UCI.
- the number of the first group of consecutive DMRS symbols may be one or more.
- Figure 5 shows four PUSCH resources-PUSCH1, PUSCH2, PUSCH3, and PUSCH4 from top to bottom (the upper and lower order is only used to logically distinguish 4 PUSCH resources and does not limit any frequency domain positional relationship).
- the start symbols of PUSCH1 and PUSCH3 are DMRS symbols, and the start symbols of PUSCH2 and PUSCH4 are not DMRS symbols.
- the first group of consecutive DMRS symbols in PUSCH1 and PUSCH2 only includes one symbol
- the first group of consecutive DMRS symbols in PUSCH3 and PUSCH4 includes multiple symbols.
- Step 1 gNB configures the standard parameter ⁇ and code rate compensation parameter for the UE through RRC signaling
- the value of the scale parameter ⁇ is greater than 0 and less than or equal to 1, and the configuration method of the bit rate compensation parameter can be configured with one set of values or multiple sets of values. If a set of values is configured, the values are directly reorganized in the subsequent steps; if multiple sets of values are configured, the index can be indicated by the downlink control information (DCI) in step 2.
- DCI downlink control information
- Step 2 The gNB sends DCI to the UE through the PDCCH.
- the DCI includes but not limited to the following information: PUSCH resources allocated to the UE, whether the PUSCH is UCI-only (or whether it contains UL-SCH), and whether the PUSCH is Frequency hopping, PUSCH transmission layer number, and modulation and coding strategy index (I MCS ), PUSCH transmission layer number N L , with The index (optional) and other parameters.
- Step 3 the UE receives the DCI, parses the PUSCH resource allocated to the UE, whether the PUSCH UCI-only, PUSCH whether frequency hopping, and I MCS, PUSCH transmission parameters such as the number of layers N L; I MCS UE obtained by look-up table Code rate R and modulation order Q m ; if there is in DCI with , The UE parses out according to the index with And use it in subsequent steps.
- Step 4 If the UE parses that the PUSCH is UCI-only, and the number of HARQ-ACK information bits that the UE needs to send is not more than 2 (that is, the number of HARQ-ACK information bits is 0, 1, or 2), the UE uses the following formula Calculate the number of reserved REs reserved for HARQ-ACK (in the following formula, 2 in the denominator is calculated based on the HARQ-ACK information bit being 2):
- the UE according to ⁇ , R, Q m , N L and other parameters, the number of HARQ-ACK coded bits G ACK , the number of CSI-part1 coded bits G CSI-part1 , and the number of CSI-part2 coded bits G CSI-part2 are calculated .
- Step 5 If the UE analyzes that PUSCH requires frequency hopping, the UE calculates the number of coded bits on hop1 and hop2 for HARQ-ACK, CSI-part1 and CSI-part2 respectively according to the following formula:
- G ACK (2) G ACK -G ACK (1)
- G CSI-part1 (2) G CSI-part1 -G CSI-part1 (1);
- G CSI-part2 (1) M 1 ⁇ N L ⁇ Q m -G CSI-part1 (1);
- G CSI-part2 (2) M 2 ⁇ N L ⁇ Q m -G CSI-part1 (2);
- the UE separately calculates the number of coded bits mapped by the reserved RE reserved for HARQ-ACK on hop1 and hop2 according to the following equations:
- Step 6 The UE maps HARQ-ACK, CSI-part1 and CSI-part2 coded bits to PUSCH according to the parameters calculated in step 5.
- Table 1 is the result obtained using the method of the prior art
- Table 2 is the result obtained using the method of the present application.
- Table 2 is the result of calculation using the communication method provided by this application. From the second to last row and the third to last row of Table 2, it can be seen that the number of coded bits transmitted by the unreserved RE on hop2 and CSI-part1 are mapped on the unpredicted Leave the same number of coded bits on the RE. From the first to last row and the fourth to last row of Table 2, it can be seen that the number of coded bits for the reserved RE mapping of hop2 Equal to the number of coded bits mapped by CSI-part2 on hop2, and all reserved REs have data transmission.
- the calculation method of the present invention aligns the number of coded bits mapped by the unreserved RE in the two hops and the number of coded bits of the CSI-part1 in the two hops, and solves the problems of the prior art.
- the number of HARQ-ACK coded bits is G ACK
- the number of HARQ-ACK coded bits sent on hop1 and hop2 are respectively:
- G ACK (2) G ACK -G ACK (1).
- the problem with the above splitting rule is that the unreserved RE of hop1 is not enough to carry the number of coded bits of CSI-part1 in hop1, resulting in incomplete transmission of CSI-part1.
- the parameter M 1 ⁇ N L ⁇ Q m -G ACK (1) on the right side of the minimum function min( ⁇ , ⁇ ) is used to limit the upper limit of the resource occupied by CSI-part1 in hop1 (hereinafter referred to as its It is the first upper limit), that is, the HARQ-ACK resource in hop1 cannot be occupied.
- the second upper limit the upper limit of the resource occupied by CSI-part1 in hop1
- G ACK is the number of coded bits calculated according to the actual number of HARQ-ACK information bits, and It is the number of coded bits mapped by the reserved RE calculated according to the number of HARQ-ACK information bits as 2. Therefore, if the actual number of HARQ-ACK information bits is 0 or 1, then there is So that for hop1 At this time, the first upper limit is greater than the second upper limit, which may cause the unreserved RE of hop1 to be insufficient to carry the number of coded bits G CSI-part1 (1) of CSI-part1 in hop1.
