- the UE determines the HARQ-ACK codebook according to the actually scheduled PDSCH. Since only the actually scheduled PDSCH is fed back, the size of the HARQ-ACK codebook is usually smaller than the semi-static HARQ-ACK codebook The size of the codebook.
- the specific type of codebook used by the UE is determined by the RRC configuration.
- DAI Downlink Control Information
- C-DAI counter DAI
- total DAI total DAI
- T-DAI total DAI
- the UE determines the codebook for HARQ-Ack feedback according to the received DAI.
- the resource in DCI has only two bits, so the UE can only judge that less than 4 PDCCH missed detections through the information of DAI.
- the following situations can be included:
- the PDSCH transmission can be a non-repetitively transmitted PDSCH, or a repeatedly transmitted PDSCH, and redundant versions of multiple PDSCHs that are repeatedly transmitted. Version, RV) can be the same or different.
- each PDCCH has a corresponding HARQ-Ack feedback bit. For example, if two PDCCHs are used to schedule a PDSCH transmission, then HARQ-Ack must be fed back to both PDCCHs, which will cause the number of feedback bits to be redundant and reduce the feedback performance. Wherein, the transmission of the two PDCCHs may be repeated transmission or non-repetitive transmission.
- the UE does not miss a part of the PDCCH.
- Check any PDCCH Therefore, when the PDCCH is introduced to repeatedly schedule PDSCH transmission, a new DAI counting method needs to be introduced, so that the UE does not need to feed back multiple HARQ-Ack bits to multiple PDCCHs that schedule the same PDSCH, and at the same time avoid detecting the same DAI.
- FIG. 2 is a flowchart of a DAI counting method provided by an embodiment of the present application. The method is applied to a terminal. As shown in FIG. 2, it includes the following steps:
- Step 201 In the case where the physical downlink control channel PDCCH is configured for repeated transmission, DAI counting is performed with reference to the PDCCH listening opportunity.
- the network device can configure whether the terminal performs PDCCH repeated transmission.
- the repeated PDCCH transmission can be understood as multiple PDCCHs scheduling the same PDSCH transmission, or the network is configured with the UE to schedule the same PDSCH transmission monitoring at multiple PDCCH monitoring opportunities.
- the foregoing reference PDCCH monitoring opportunity may be any one of the PDCCH monitoring opportunities corresponding to the multiple PDCCHs configured to be repeatedly transmitted.
- the foregoing reference PDCCH monitoring opportunity may be specifically indicated by the network device, or may be agreed upon by the protocol. Since the reference PDCCH monitoring opportunity is defined, the DAI can be counted according to the monitoring opportunity where the detected PDCCH is located. Specifically, it can first determine whether the monitoring opportunity where the currently detected PDCCH is located is a reference PDCCH monitoring opportunity.
- the DAI count can be performed at the monitoring opportunity according to the DAI value carried by the detected PDCCH ; If the monitoring opportunity is not a reference PDCCH monitoring opportunity, then DAI counting is not performed at this monitoring opportunity, or in other words, DAI counting is not performed. If DAI is counted, the detected DAI is compared with the temporary DAI. The DAI counting is not performed, that is, the detected DAI is not used for comparison with the temporary DAI, and the temporary DAI is the DAI value currently stored by the UE.
- the embodiment of this application defines DAI counting at the reference PDCCH listening opportunity. In this way, in the scenario of multiple PDCCH repeated transmission, there is no need to feed back multiple HARQ-Ack bits for multiple PDCCHs that schedule the same PDSCH. In the case of detecting the same DAI, it is considered that there is a missed detection of the PDCCH. Therefore, the embodiment of the present application solves the problem of DAI counting in a scenario where multiple PDCCHs are repeatedly transmitted.
- the reference PDCCH monitoring opportunity includes any one of the following:
- the first PDCCH monitoring opportunity or the last PDCCH monitoring opportunity Among the M PDCCH monitoring opportunities corresponding to the repeated M PDCCHs, the first PDCCH monitoring opportunity or the last PDCCH monitoring opportunity; where M is an integer greater than 1.
- the above-mentioned reference PDCCH monitoring opportunity may be indicated by a network device, or may be agreed upon by a protocol.
- the network device may indicate the specific PDCCH monitoring opportunity as the reference PDCCH monitoring opportunity.
- the network device may indicate the reference PDCCH monitoring opportunity through signaling such as RRC and DCI.
- the network device may indicate the reference PDCCH monitoring opportunity when configuring the terminal for repeated PDCCH transmission, and the indicated reference monitoring opportunity may be any one of the multiple PDCCH monitoring opportunities configured for repeated transmission.
- a certain monitoring opportunity of the multiple PDCCH monitoring opportunities that are repeatedly transmitted may be configured as a reference PDCCH monitoring opportunity through a protocol agreement. For example, among the M PDCCH monitoring opportunities corresponding to the repeated M PDCCHs, the first PDCCH monitoring opportunity or the last PDCCH monitoring opportunity.
- the position of the foregoing reference PDCCH monitoring opportunity is determined according to any one of the following:
- the first indication information carried by the PDCCH where the first indication information is used to indicate the sort position of the PDCCH in the M PDCCHs.
- the network device may indicate the first PDCCH monitoring opportunity among the M PDCCH monitoring opportunities corresponding to the M PDCCHs. After determining the first PDCCH monitoring opportunity, the terminal can determine the position corresponding to the reference PDCCH monitoring opportunity. Specifically, the network device may indicate in the PDCCH transmitted corresponding to the first PDCCH monitoring opportunity that the PDCCH is the PDCCH transmitted at the first PDCCH monitoring opportunity. For example, it may indicate the PDCCH transmitted in the PDCCH transmitted at the first PDCCH monitoring opportunity. The PDCCH is the first PDCCH. The first PDCCH can understand the PDCCH transmitted by the first PDCCH monitoring opportunity among the M PDCCH monitoring opportunities.
- the M PDCCH monitoring opportunities correspond to the transmission of the M PDCCHs. PDCCH for one transmission. If the last PDCCH monitoring opportunity is a reference monitoring opportunity, the terminal can determine the first PDCCH monitoring opportunity according to this information to determine other ordered PDCCH monitoring opportunities, for example, determine the M-1th PDCCH monitoring opportunity after the first PDCCH monitoring opportunity It is the last PDCCH monitoring opportunity, and is used as a reference PDCCH monitoring opportunity. Of course, other signaling can also be used to indicate the location of the first PDCCH monitoring opportunity.
- the PDCCH may directly carry the first indication information used to indicate the sorting position of the PDCCH in the M PDCCHs.
- the sort position can be understood as: the position of the PDCCH transmission in the configured M PDCCH transmissions, such as the Nth PDCCH transmission or the Nth PDCCH.
- the Nth PDCCH transmission can be understood as the PDCCH transmitted at the Nth PDCCH monitoring opportunity among the M PDCCH monitoring opportunities corresponding to the repeated M PDCCHs, and N is a positive integer less than or equal to M.
- the reference PDCCH monitoring opportunity is the third PDCCH monitoring opportunity.
- the terminal can determine the reference PDCCH monitoring opportunity according to the indication information.
- the terminal detects that the first indication information in the PDCCH indicates the If the PDCCH is the N-1th PDCCH transmission, or the N-1th PDCCH monitoring opportunity, the terminal can determine that the next PDCCH monitoring opportunity is the Nth PDCCH monitoring opportunity, that is, the Nth PDCCH monitoring opportunity, which is determined to be the PDCCH reference monitoring Opportunity; in the same way, if the first PDCCH monitoring opportunity, or the first PDCCH transmission is a reference PDCCH monitoring opportunity, the terminal can also forward the first PDCCH monitoring opportunity in turn to determine the reference PDCCH monitoring opportunity.
- indication information can be introduced in the PDCCH to indicate whether the DAI field in the PDCCH of the terminal is counted. If the information indicates that DAI counting is performed, the UE performs DAI counting; otherwise, the terminal does not perform DAI counting. That is, the UE ignores the DAI value at the current PDCCH monitoring opportunity.
- the method may not be limited to that the network is configured with repeated PDCCH transmission, or configured with multiple PDCCH monitoring opportunities to detect the same PDSCH scheduling information.
- the performing DAI counting at the reference PDCCH monitoring opportunity includes:
- the DAI value in the detected PDCCH is counted at the reference PDCCH monitoring opportunity.
- the DAI value when counting the DAI with reference to the PDCCH listening opportunity, it may be the DAI value corresponding to the DAI carried by any PDCCH of the M PDCCHs.
- the DAI value may be detected for the reference listening opportunity, or it may be the reference listening opportunity The DAI value has been detected before, so no further restrictions will be made here.
- the method further includes:
- DAI since DAI usually uses a small number of bits, for example, there are only 2 bits. Then, if 4 PDCCHs are not transmitted, the value of C-DAI will be repeated, that is, DAI has completed one round of the cycle, and the counter j is used to count the number of cycles of the DAI value to determine how many rounds of the DAI value have been cycled to determine The number of bits in the HARQ-Ack codebook.
- the 4 PDCCHs means that 4 PDCCHs need to be sent, and each PDCCH has multiple repeated transmissions, that is, there are multiple PDCCH monitoring opportunities for each PDCCH. It should be understood that when the number of numerical cycles is counted, an increment operation can be performed each time.
- determining whether to count the counter of the number of DAI cycles includes:
- the counter of the number of DAI cycles does not count
- the preset conditions include:
- N PDCCHs are detected at the PDCCH monitoring opportunity for repeated PDCCH transmission, and the values of DAI carried by the N PDCCHs are the same.
- the preset condition further includes:
- the physical downlink shared channel PDSCH scheduling information scheduled by the N PDCCHs is the same.
- the PDSCH scheduling information may include at least one of the following: New Data Indicator (NDI), HARQ process number (process number), PDSCH resources, transport block size, redundancy version, HARQ
- NDI New Data Indicator
- process number process number
- PDSCH resources transport block size
- redundancy version HARQ
- MCS Modulation and Coding Scheme
- the foregoing possible DAI includes at least one of a counter DAI and a total DAI.
- the aforementioned PDSCH resources may include at least one of the following: time-frequency resources, carrier, mapping mode, demodulation reference signal (Demodulation Reference Signal, DMRS), resource allocation mode, and so on.
- the mapping mode may include whether frequency hopping.
- the method further includes:
- the hybrid automatic repeat request response HARQ-ACK codebook is determined, and L is a positive integer greater than 1.
- the UE may detect PDCCHs with the same or different DAI values, and the detected PDSCH scheduling information of the L PDCCHs are the same, then according to the detected DAI values in the L PDCCHs and the L PDCCHs DCI repetition count information of the downlink control information, determine the HARQ-ACK codebook for the hybrid automatic repeat request response.
- the manner of determining the HARQ-Ack codebook may be: for the PDCCH with the same PDSCH scheduling information, the HARQ-Ack feedback information is fed back once.
- X 2 ⁇ Q
- x is the difference between the DAI value detected by the terminal and the stored DAI value.
- the DAI value carried in the PDCCH is compared with the currently stored DAI value to obtain the difference x.
