- uplink data both downlink data transmission and HARQ-ACK feedback are applicable.
- the main idea is to illustrate the basic idea of the method. For example, the formation of two types of HARQ-ACKs.
- the method can be used for HARQ-ACK feedback of downlink data, which can also be used for uplink data), when HARQ-ACKs required for receiving multiple transport blocks TB are in one PUCCH
- the number of CBG HARQ-ACK bits per TB feedback is 10 bits.
- the UE receives TB1, TB2, TB3, TB4 and TB5 in slot n, slot n+1, slot n+2, slot n+3, slot n+4, respectively. These TBs are required to be in slot n.
- HARQ-ACK feedback is performed in +6. It is assumed that the decoding condition of the UE for TB1 to TB5 is TB1, the decoding of TB2 and TB4 is correct (the CRC of TB is passed), the decoding of TB3 and TB5 is incorrect, and all of the CBGs are correct (the CRC check of all CBs included in the CBG is passed) ), some CBG errors.
- the TB-level HARQ-ACKs formed by the UE are: 11010, 1 indicates ACK (correct reception), and 0 indicates NACK (not correctly received).
- CBG-level HARQ-ACKs are formed for TB3 and TB5 (here, in TB3, the first and second CBGs are not correctly received, and the remaining CBGs are correctly received, and the first to fourth CBGs in TB5 are not correctly received, and the remaining CBGs are correctly received.
- the probability of a data transmission being correct is 90%, which, in this way, actually saves 90% of the bits in this example. So the bit overhead saved in this way is very significant.
- the transmitting end receives the TB level HARQ-ACKs, and then determines the TB which is NACK according to the TB level HARQ-ACKs, and then determines the number of bits and each tag of the CBG HARQ-ACKs according to the number and order of the TBs marked as NACK.
- CBG HARQ-ACKs bits for TB of NACK For example, after receiving the TB-level HARQ-ACKs, the sender will find that the 3rd and 5th TBs are marked as NACK after decoding, and further consider that there are CBGs corresponding to the 3rd and 5th TBs in the CBG HARQ-ACKs. Level of HARQ-ACKs.
- the transmitting end then decodes the CBG HARQ-ACKs to obtain the CBG HARQ-ACKs of the 3rd and 5th TBs. In this way, the sender considers that the first, second, and fourth TBs are correctly received without retransmission, and the third and fifth TBs are not correctly decoded.
- the CBG marked as NACK needs to be retransmitted (actually Retransmission of CBs in CBGs marked as NACK).
- the number of CBG HARQ-ACK bits fed back by each TB may correspond to one bit per CBG.
- Each TB is divided into several CBGs, which may be configured by the transmitting end through RRC signaling and/or physical layer signaling, or may be configured by the transmitting end to configure a total CBG value for multiple TBs, and then CBGs of different TBs.
- the number is related according to the number of layers used in the TB transmission. For example, the more the number of layers, the more the number of CBGs corresponding to the TB from the total CBG value. It may also be the number of CBGs configured for each TB through high layer RRC signaling.
- the specific sending methods include the following:
- the code After connecting multiple types of HARQ-ACKs in series, the code is modulated and transmitted.
- the number of bits of the second type of HARQ-ACKs is changed according to the number of TBs marked as NACK each time. Therefore, if two types of HARQ-ACKs are concatenated, then coded and then transmitted, it may cause the sender to receive.
- the detection complexity is increased when the HARQ-ACKs fed back by the receiving end, but this method only needs to use one PUCCH channel. Further, consider combining methods that reduce detection complexity, such as combining rate matching. Since the resource for transmitting HARQ-ACKs and the modulation and coding information MCS allocated by the transmitting end for the receiving end are both configured, the receiving end modulates and codes according to the modulation and coding strategy (MCS) information, and then maps the resource to the resource through rate matching.
- MCS modulation and coding strategy
- Uplink Control Information (UCI) (including HARQ-ACKs) corresponds to different PUCCH formats according to the number of transmitted bits. Also, the number of symbols used in the NR according to the PUCCH corresponds to a different PUCCH transmission scheme (for convenience, the PUCCH is divided into a short PUCCH and a long PUCCH). The short PUCCH occupies 1 to 2 symbols, and the number of long PUCCH symbols is greater than 4.
- the PUCCH format in the text includes the number of symbols used by the PUCCH and the number of bits to be transmitted, meaning of two levels.
- the PUCCH format for example, for a UCT of 1 to 2 bits, if one or two symbols are configured, one PUCCH format will be used; if configured for at least four symbols, another PUCCH format will be used. .
- a PUCCH format will be used, if configured as at least 4 symbols
- Another PUCCH format will be used; for more than X bits, if configured for at least 4 symbols, another PUCCH format will be used.
- the PUCCH format for the case of greater than or equal to 3, less than or equal to X bits, if configured as 1 or 2 symbols, one PUCCH format will be used, and if configured to be at least 4 symbols, another PUCCH format will be used.
- the first type is determined because the total number of TBs is determined (the sender is aware) and the TB HARQ-ACK of one bit per TB, so the total number of bits of the first type of HARQ-ACKs is determined. Then, according to the number of symbols configured by the sender, the corresponding PUCCH format is determined to be transmitted on the allocated resources. In the second type, the total number of bits is changed.
- the resources allocated by the sender are also allocated according to the maximum demand. However, when the receiver sends the packet, it does not need to be mapped to all resources, and only needs to be sent according to the configured parameters. .
- the sender first decodes the first type of HARQ-ACKs, knows the number of TBs and the sequence position marked as NACK, and then determines the total number of bits of the second type of HARQ-ACKs according to the TB marked as NACK, and then decodes The second type of HARQ-ACKs.
- the PUCCH format specifically used by the two types is relatively large, and can be determined according to the bit number allocation.
- two long PUCCHs are respectively corresponding, and two long PUCCHs are allowed to be time division or frequency division multiplexed; or two short PUCCHs are respectively allowed, and two long PUCCHs are allowed to be time division or frequency division multiplexed; or one corresponding to a long PUCCH,
- the other corresponds to a short PUCCH and allows two PUCCHs to be time division multiplexed.
- the same resource may be allocated to the two types of HARQ-ACKs, and the PUCCH corresponding to the two HARQ-ACKs is frequency-divided or time-division or code-multiplexed in the resource.
- the transmitting end configures a PUCCH resource set for the receiving end.
- a PUCCH resource set there are multiple specific PUCCH resources corresponding to different formats, different symbol numbers, and different bit numbers.
- the collections are included:
- a specific PUCCH resource 1 that transmits a 1-bit HARQ-ACK and one symbol (including a symbol position);
- a specific PUCCH resource 2 transmitting 1 bit HARQ-ACK and 2 symbols (including symbol positions);
- a specific PUCCH resource 3 transmitting 2 bits of HARQ-ACKs and 1 symbol (including symbol positions);
- a specific PUCCH resource 4 that transmits 2 bits of HARQ-ACKs and 2 symbols (including symbol positions);
- N is greater than or equal to 4, less than or equal to 14, N is different, there are multiple specific PUCCH resources) symbols (including symbol positions);
- the specific value of X is still under discussion, for example, the value is 11, or 22.
- N is greater than or equal to 4, less than or equal to 14, N is different, there are multiple specific PUCCH resources) symbols (including symbol locations);
- the transmitting end may configure a suitable set for the receiving end, for example, configuring four possible PUCCH resources, and then the receiving end according to the number of bits of the formed HARQ-ACKs from the configured set (also combining the number of OFDM symbols required by the PUCCH) Selecting a suitable specific PUCCH resource to transmit corresponding HARQ-ACKs respectively.
- the receiving end may also implicitly notify the transmitting end of the specific PUCCH resource selected by the DMRS of the PUCCH in the example 4. This comparison is suitable for a plurality of identical specific PUCCH resources in the set.
- An example is the configuration of a PUCCH resource set, which can independently apply the configuration of the PUCCH resource set.
- a plurality of specific PUCCH resources included in the current PUCCH resource refer to frequency domain resources. To save overhead, it is recommended to perform a new definition for the PUCCH resource set.
- a specific PUCCH resource may also have more attributes (except the resource attributes of the frequency domain), for example, may also include a PUCCH format, a PUCCH start symbol, and a PUCCH duration (eg, PUCCH). The number of symbols), the slot in which the PUCCH is located, whether it is frequency hopping, sequence or codeword information. These attributes can be represented in a tabular or joint encoding.
- Each specific PUCCH resource in the PUCCH resource set includes: a physical resource block (PRB) index, a PUCCH start symbol, a duration, and a slot information. Then for a 1 to 2 bit PUCCH, the sequence or codeword information needs to be increased. Sequence or codeword information is not required for PUCCHs larger than 2 bits.
- a PUCCH resource set includes n specific PUCCH resources, and the value of n can be determined according to the requirements of the UE. For example, when the UE is in static or low speed, the value of n can be configured to be small; if the UE is moving at a high speed, the value of n can be configured to be large.
- PUCCH format it can be determined according to the number of bits to be fed back and the number of symbols (duration duration) for allocating a specific PUCCH, since both the base station and the UE know the number of bits that need to be fed back, so the PUCCH format can be implicit. Whether PUCCH is frequency hopping is directly configured through high layer signaling.
- the specific operation is: the base station configures a PUCCH resource set for the UE, and has a frequency domain resource, a start symbol, a duration, and a corresponding slot for each specific PUCCH resource in the set. Typically, four specific PUCCH resources are configured. Then, the specific used PUCCH resource is indicated by the physical layer signaling for each UE feedback from the set. For a PUCCH of 1 to 2 bits, the base station also configures sequence or codeword information corresponding to the corresponding 1 to 2 bits of information for each specific PUCCH resource. The UE receives the PUCCH resource set configured by the base station, determines the specific PUCCH resource corresponding to the current feedback according to the indication signaling of the physical layer, and then performs PUCCH transmission according to the requirement of the PUCCH resource.
- the resource derives the resource corresponding to the PUCCH of the CBG HARQ-ACKs. This saves signaling for allocating resources for another type of PUCCH. Considering that the total number of bits of the TB-level HARQ-ACKs is determined, it is allocated a corresponding PUCCH resource, and then the PUCCH resources of another type of HARQ-ACKs are deduced according to the agreed rules by its PUCCH resources.
- both types of HARQ-ACKs are long PUCCHs, they can be configured to share the same frequency domain resources. And their time domain symbols are contiguous, it can be understood that two PUCCHs are time divisions in the same frequency domain resource.
- the two types of HARQ-ACKs have the same frequency domain resource intra-frequency division multiplexing, and some resources in the resource are reserved for the first type of HARQ-ACKs, and then some physical resource blocks or sub-parts are agreed.
- the carrier is given to the second type of HARQ-ACKs.
- the two resources are multiplexed according to the agreed pattern in the frequency domain, or the two types of HARQ-ACKs respectively occupy part of the frequency domain resources (in units of physical resource blocks PRB or subcarriers) and the frequency domain resources of the two parts are continuous.
- the initial frequency domain position corresponding to the second type of HARQ-ACKs is implicitly obtained by the end type of the first type of HARQ-ACKs, and the number of persistent resources in the frequency domain can be marked according to the TB level in the HARQ-ACKs.
- the number of TBs of NACK and the number of CBGs per TB are determined.
- the total bit of the TB HARQ-ACKs is 10 bits, 5 bits are NACK, 5 bits are ACK, so the PUCCH format corresponding to the medium load is used for transmission, and the transmitting end allocates a PRB (assumed to be PRBn) to the receiving end for transmission.
- PUCCH of TB HARQ-ACKs it is assumed that each TB has 10 CBGs, and each CBG has one HARQ-ACK.
- the CBG HARQ-ACKs have 50 bits, and according to the coding modulation mode configured by the transmitting end for the 50-bit HARQ-ACKs, four PRBs are required ( It is assumed that 4 PRBs are required for transmission.
- the resources of the second HARQ-ACKs are consecutive 4 PRBs after the PRBn.
- both the transmitting end and the receiving end can obtain the resources of the second HARQ-ACKs according to the first PRBn, thereby saving signaling for allocating resources for the second HARQ-ACKs resource.
- the TB HARQ-ACK and the CBG HARQ-ACK are respectively fed back to the transmitting end by using the adjacent first resource and the second resource.
- the second resource is reserved according to the total number of TBs scheduled and the preset transmission error probability. For example, there is another method for allocating resources for the PUCCH of the second HARQ-ACKs. Considering that its number of bits is related to the number of TBs transmitted, and the statistical probability of a TB transmission error is 10%, it can be allocated a corresponding resource size according to the total number of scheduled TBs. For example, if 10 TBs are scheduled, then one TB can be decoded, so that the CBG HARQ-ACK bit corresponds to one TB, thereby allocating resources for it. More conservative can increase the ratio.
- the allocated resource may adopt the above manner, and there is an agreed relationship between the resource of the TB HARQ-ACK and the resource of the CBG HARQ-ACK, so that only the resource of the TB HARQ-ACK needs to be notified, thereby reducing the resource allocation. Signaling.
- Resources are reserved based on the number of TBs scheduled and the preset probability.
- Case 3 When the CRC check of the CB in the TBs fails, and the CRC of the TBs is not verified, only the TB HARQ-ACKs are transmitted and both are NACK, and the CBG HARQ-ACKs are not transmitted.
- the receiving end notifies the sending end by using the DMRS, and the receiving end transmits the format information used by the PUCCH and/or the specific PUCCH resource information.
- the main purpose of this mode is to determine the number of HARQ-ACKs bits to be fed back according to the actual decoding situation, and then determine the specific PUCCH format to be transmitted in the allocated resources.
- the allocated resource may also be a resource set from one PUCCH configured by the sender, and the UE selects a specific PUCCH resource from the set.
- the transmitting end needs to detect multiple possibilities blindly, which increases the complexity.
- the related information of the DMRS using the PUCCH in this example implicitly informs the transmitting end, the PUCCH format used by the receiving end, and/or the specific PUCCH resource, because the transmitting end needs to decode the DMRS before decoding the PUCCH, so the DMRS using the PUCCH is used.
- the related information implicitly informs the sender that it is convenient and does not increase overhead. It is also relatively easy to consider that the transmitting end detects the DMRS related information.
- the PUCCH format information used by the receiving end can be implicitly notified by the DMRS, where the PUCCH format information includes at least one of the following: a short format, a long format, a PUCCH symbol number, and a PUCCH symbol position.
- the PUCCH format information may also be a different PUCCH format in the PUCCH resource set configured by the transmitting end for the receiving end or a PUCCH format set configured by the transmitting end for the receiving end, indicating which format is used specifically.
- the specific PUCCH resource information of the PUCCH used by the receiving end can be implicitly notified by the DMRS.
- the transmitting end configures a PUCCH resource set for the receiving end, and includes a plurality of specific PUCCH resources.
- the receiving end implicitly notifies the receiving end which specific PUCCH resource is used by the DMRS.
- the PUCCH resource in the set has a binding relationship with at least one of a PUCCH format, a PUCCH symbol number, and a PUCCH symbol position (a location in a slot).
- the specific PUCCH resource in the set corresponds to its own PUCCH format; the specific PUCCH resource in the set corresponds to its own PUCCH symbol number and symbol position; in the set, different specific PUCCH resources have their own PUCCH format. And the number of symbols and the position of the symbol. It can also be understood that one PUCCH resource in the set corresponds to its own transmission mode.
- the receiving end selects or configures a specific PUCCH resource, the corresponding code modulation mode, the number of matches and the symbol position are determined.
- the DMRS implicit notification specifically including at least one of the following ways:
- a HARQ-ACK for forming 1 bit for the multiple TBs is further added, as follows:
- a specific PUCCH resource in the PUCCH resource set configured by the transmitting end for the receiving end corresponds to a 1-bit HARQ-ACK format.
- the feedback of the receiving end is received from the specific PUCCH resource in the PUCCH resource set. If the decoding is ACK, the sender considers that all TBs are correctly received by the receiving end.
- a NACK of one bit is fed back (this is regarded as a third type of HARQ-ACK), and all TB TB-level HARQ-ACKs are not sent, and the TB marked as NACK (Currently for all TB) CBG HARQ-ACKs are sent.
- the probability of occurrence of this situation is very low, because the transmission of the transmission data channel introduces various guarantee mechanisms, so the statistical probability of transmission reliability is 90%.
- the manner in the above implementation may be adopted, such as the manner of determining the resource, the manner of determining the format, and the like.
- a specific PUCCH resource in the PUCCH resource set configured by the transmitting end for the receiving end corresponds to a 1-bit HARQ-ACK format.
- the feedback of the receiving end is received from the specific PUCCH resource in the PUCCH resource set.
- the transmitting end considers that all TBs are not correctly received by the receiving end, and then receives the CBG HARQ-ACKs from another specific PUCCH resource (here, it is assumed that there is a specific PUCCH resource corresponding to the transmission in the PUCCH resource.
- Multi-bit HARQ-ACKs format after correct decoding, retransmit each TB error CBG.
- the number of bits of the HARQ-ACKs can be reduced by using the embodiment, thereby reducing the overhead and saving the power consumption of the receiving end. It does not affect the performance of CBG retransmission.
