The following describes in detail a feedback information sending method according to an embodiment of the present application with reference to the accompanying drawings and a specific embodiment and an application scenario thereof.
Fig. 2 shows a flowchart of a feedback information sending method provided in an embodiment of the present application, where the method may be executed by a terminal, in other words, the method may be executed by software or hardware installed in the terminal. As shown in fig. 2, the method may include the following steps.
Step S201, determining a feedback position corresponding to the physical downlink shared channel scheduled by the downlink control information according to the feedback mode and the received target parameter value and according to a first rule.
The target parameter value may be selected from k1 sets configured in a higher layer, and when the number of k1 candidate values included in k1 sets is greater than 1, which k1 value is specifically adopted as the target parameter value may be indicated in the downlink control information. The target parameter value may also be carried by downlink control information.
There are various feedback mode setting methods, and in one embodiment, a default feedback mode may be set in advance for the terminal, and the default feedback mode may be indicated by a high-level indication or a protocol. In another embodiment, the feedback mode is determined by the first indication information.
Wherein the first indication information is obtained by at least one of the following methods:
pre-defining according to a protocol;
according to the base station indication;
according to the high-level indication;
indicated by an indication field carried in the downlink control information.
The terminal can select one of multiple preset feedback modes through the received first indication information, and determine a feedback position corresponding to each scheduled PDSCH according to a first rule by combining the received target parameter value, so as to send feedback information corresponding to the PDSCH, such as HARQ-ACK, at the feedback position.
It should be understood that the feedback position is located in a Channel for Uplink transmission, which may be a Physical Uplink Control Channel (PUCCH) or a Physical Uplink Shared Channel (PUSCH).
Therefore, according to the feedback information sending method provided by the embodiment of the application, the terminal can determine the feedback position corresponding to the physical downlink shared channel scheduled by the downlink control information according to the feedback mode and the received target parameter value and the first rule, so that the terminal can confirm the feedback position of each physical downlink shared channel under the condition that one downlink control information schedules a plurality of PDSCHs, accurate transmission of the feedback information is ensured, and the transmission efficiency of data is improved.
Fig. 3 shows another flowchart of a feedback information sending method provided in an embodiment of the present application, where the method may be executed by a terminal, in other words, the method may be executed by software or hardware installed in the terminal. As shown in fig. 3, the method may include the steps of:
step S301, under the condition that the feedback mode is that the received physical downlink shared channels perform feedback at the same time, determining feedback positions corresponding to all the physical downlink shared channels by taking a first time slot where the first physical downlink shared channel is located as a reference according to a received first target parameter value; wherein the first target parameter value indicates an interval of the feedback position from the first slot.
There are various feedback setting methods.
In one embodiment, a default feedback mode may be preset for the terminal in advance, and the default feedback mode may be indicated by a higher layer or a protocol.
In another embodiment, the feedback mode is determined by the first indication information;
wherein the first indication information is obtained by at least one of the following methods:
predefining according to a protocol;
according to the base station indication;
according to the high-level indication;
indicated by an indication field carried in the downlink control information.
The first physical downlink shared information may be any scheduled PDSCH, and in one embodiment, the first physical downlink shared channel is the last PDSCH or the first PDSCH in the scheduled PDSCH.
It should be understood that the first target parameter value is a numerical value, i.e., a value of K1.
As shown in fig. 4, DCI D1 schedules multiple PDSCHs P1-P5, and according to the value of k1, a feedback position B1 corresponding to each PDSCH can be determined, where an interval between the feedback position B1 and the last PDSCH P5 is indicated by k1, for example, if the last PDSCH P5 is located in n, the slot where the feedback position is located is n + k 1. Equivalently, only one value of k1 is needed to determine the feedback position of each PDSCH scheduled.
Therefore, according to the feedback information sending method provided in the embodiment of the present application, when the feedback manner is that the received physical downlink shared channels are fed back at the same time, the feedback positions corresponding to all the physical downlink shared channels are determined according to the received first target parameter value with the first time slot where the first physical downlink shared channel is located as a reference, so that when one downlink control information schedules multiple PDSCHs, the terminal can confirm the feedback position of each physical downlink shared channel through a small DCI overhead, ensure accurate transmission of feedback information, and improve data transmission efficiency.
Fig. 5 shows another flowchart of a feedback information sending method provided in an embodiment of the present application, where the method may be executed by a terminal, in other words, the method may be executed by software or hardware installed in the terminal. As shown in fig. 5, the method may include the steps of:
step S501, grouping the received physical downlink shared channels when the feedback mode is that the received physical downlink shared channels perform feedback at different times.
There are various feedback setting methods. In one embodiment, a default feedback mode may be preset for the terminal in advance, and the default feedback mode may be indicated by a higher layer or a protocol. In another embodiment, the feedback mode is determined by the first indication information;
wherein the first indication information is obtained by at least one of the following methods:
pre-defining according to a protocol;
according to the base station indication;
according to the high-level indication;
indicated by an indication field carried in the downlink control information.
Further, the grouping the received physical downlink shared channels includes:
grouping the received physical downlink shared channels according to the following at least one grouping parameter;
wherein the grouping parameters include:
a first number of physical downlink shared channels included in each packet;
each packet includes a second number of time slots occupied by the physical downlink shared channel.
The calling mode of the called PDSCH can be set according to actual needs, and comprises the following steps: each PDSCH occupies one slot (slot), and a plurality of PDSCHs may be scheduled in one slot. Therefore, when grouping is performed, corresponding grouping parameters can be set according to the transmission mode of the PDSCH. For example, for a mode in which each PDSCH occupies one slot, only the first number or the second number needs to be determined for grouping. When the multiple PDSCHs are called for one slot, grouping is performed according to a combination of the first number and the second number.
In one embodiment, the scheduled multiple PDSCHs may be grouped based on a first number L, one group of every L PDSCHs, up to the last PDSCH scheduled.
In another embodiment, the plurality of time slots in which the scheduled PDSCHs are located may be grouped based on the second number N, with PDSCHs included in every N time slots as a group until the time slot in which the last scheduled PDSCH is located.
Further, the first number or the second number is determined by at least one of:
protocol pre-configuration;
a high-level indication;
subcarrier Spacing (SCS) of the received physical downlink control channel;
the subcarrier interval of the physical downlink shared channel is scheduled; equivalently, according to the scaling relationship between the different SCS received or scheduled and the first data or the second number, e.g. default SCS480K, 4 PDSCH are grouped; SCS 960K, 8 PDSCHs in a group;
bit length of the feedback information. A bit (bit) length of the feedback information needs to be acquired in case that a single DCI schedules a plurality of PDSCHs.
Further, the bit length of the feedback information is determined by at least one of:
pre-configuring a protocol;
a high-level indication;
the subcarrier interval of the received physical downlink control channel;
and the subcarrier interval of the scheduled physical downlink shared channel.
For example, a protocol pre-configures a fixed bit length for feeding back each time when a plurality of PDSCHs are scheduled by DCI, and if default feedback information is HARQ-ACK with a bit length of 4bits, grouping the plurality of PDSCHs according to the 4 bits. Taking the example of grouping according to the first number, assuming that there are 16 PDSCHs in total, every 4 are grouped; assuming a total of 8 PDSCHs, every 2 is a group; assuming a total of 14 PDSCHs, the first three groups each contain 4 PDSCHs and the last group contains 2 PDSCHs, or the groups may be grouped such that the first group contains 2 PDSCHs and the last three groups contain 4 PDSCHs. In the grouping process, the number of PDSCHs contained in each group can be set according to needs to ensure that the bit length of the HARQ-ACK fed back each time is consistent. Taking grouping according to the second number as an example, assuming that 16 slots are occupied by 20 PDSCHs in total, every 4 PDSCHs are grouped to ensure that the number of bits of the fed-back HARQ-ACK is consistent.
Step S502, determining the feedback position corresponding to each group according to the grouping result and the received target parameter value.
And according to the grouping result, combining the received target parameter values to respectively determine the feedback position of each PDSCH grouping.
The received target parameter value may be selected from k1 sets configured by a higher layer, and when the k1 candidate values included in the k1 set are greater than 1, which k1 value is specifically adopted as the target parameter value may be indicated in the received downlink control information. The target parameter value may also be carried by downlink control information.
It should be understood that the feedback positions corresponding to the obtained groups may be different, the same, or partially the same. Taking three packets as an example, the first packet, the second packet and the third packet correspond to feedback positions B1, B2 and B3, respectively, then B1, B2 and B3 may be three different slots, may also be the same slot, or 2 of them are in the same slot. For simplicity, in the following embodiments, the example of three different time slots are B1, B2 and B3.
Therefore, in the feedback information sending method provided by the embodiment of the present application, when the feedback manner is that the received physical downlink shared channels are fed back at different times, the received physical downlink shared channels are grouped; and determining the feedback position corresponding to each group according to the grouping result and the received target parameter value, so that the terminal confirms the feedback position of each physical downlink shared channel under the condition that one downlink control information schedules a plurality of PDSCHs, the accurate transmission of the feedback information is ensured, and the transmission efficiency of data is improved.
Fig. 6 shows another flowchart of a feedback information sending method provided in an embodiment of the present application, where the method may be executed by a terminal, in other words, the method may be executed by software or hardware installed in the terminal. As shown in fig. 6, the method may include the steps of:
step S601, grouping the received physical downlink shared channels when the feedback mode is that the received physical downlink shared channels perform feedback at different times.
The method executed in step S601 is the same as that in step S501, and the same or similar beneficial effects are obtained, and the details of the same parts are not repeated herein.
Step S602, determining a feedback position corresponding to each group according to a target parameter value received in the downlink control information and a corresponding relation between the target parameter value and each group.
The target parameter value received by the terminal from the downlink control information has a correspondence relationship (combination) with each PDSCH packet.
In one embodiment, the target parameter values received in the downlink control information include second target parameter values respectively corresponding to the groups; and the second target parameter value takes the time slot of the second physical downlink shared channel in the corresponding group as a reference.
The second physical downlink shared channel may be any one of the assigned PDSCHs in the group, and in an embodiment, the second physical downlink shared channel is the last physical downlink shared channel or the first physical downlink shared channel in the group where the second physical downlink shared channel is located.
As shown in fig. 7, the result for the grouping of PDSCH is P1 and P2 as PDSCH first packets, P3 and P4 as PDSCH second packets, and P5 as PDSCH third packets. The received target parameter values include: the first group corresponds to k1 ═ 10, the second group corresponds to k1 ═ 11, and the third group corresponds to k1 ═ 15. The slot B1 of the PUCCH or PUSCH corresponding to the first packet is obtained as the feedback position at an interval of k1 ═ 10 with respect to the slot of the last PDSCH P2 of the first packet. And taking the slot of the last PDSCH P4 in the second packet as a reference, and taking k 1-11 as an interval, obtaining the slot B2 of the PUCCH or PUSCH as a feedback position corresponding to the second packet. The slot B3 in which the feedback position of the PUCCH or PUSCH corresponding to the third packet is located is obtained at intervals of k1 ═ 15 with respect to the slot in which the last PDSCH P5 of the third packet is located.
In another embodiment, the target parameter value received in the downlink control information includes a third target parameter value corresponding to the first packet; and the third target parameter value takes the time slot of the second physical downlink shared channel of the first group as a reference.
One target parameter value, i.e. a third target parameter value corresponding to the first packet, is provided in the DCI.
The first packet is the first packet or the last packet in all packets, or any designated packet.
And the terminal determines the feedback position corresponding to each group according to the third target parameter value and the grouping sequence.
In an embodiment, when the third target parameter value indicates that the feedback position corresponding to the first packet is in the first time slot, sequentially adding 1 or subtracting 1 according to the packet order with reference to the first time slot, and determining the time slot in which the feedback position corresponding to each packet is located, where the time slot in which the feedback position is located is the time slot for uplink transmission.
In one embodiment, if the timeslot after adding 1 or subtracting 1 is the timeslot for downlink transmission, the timeslot is skipped and the 1 addition or subtraction is continued until the timeslot is the timeslot for uplink transmission.
As shown in fig. 8, P1 and P2 are PDSCH first packets, P3 and P4 are PDSCH second packets, and P5 is PDSCH third packets. The terminal receives the third target parameter k1 corresponding to the first group, and with the time slot of the first PDSCH P1 in the first group as the reference, first obtains the feedback position B1 corresponding to the first group, and sequentially adds 1 to the feedback positions corresponding to other groups to obtain the feedback position B2 corresponding to the second group and the feedback position B3 corresponding to the third group.
As shown in fig. 9, after the feedback positions B1 and B2 corresponding to the first packet and the second packet are obtained, since the time slot after B2 is the time slot for downlink transmission, when determining the feedback position corresponding to the third packet by sequentially adding 1, it is necessary to continuously skip two time slots B3 and B4 for downlink transmission, and take B5 as the feedback position corresponding to the third packet.
As shown in fig. 8, taking subtracting 1 in sequence as an example, the third target parameter k1 corresponding to the third packet is received, and the feedback position B3 corresponding to the third packet is obtained first by taking the slot where the last PDSCH P5 in the third packet is located as a reference, and then subtracting 1 in sequence according to the feedback positions corresponding to other packets, so as to obtain the feedback position B2 corresponding to the second packet and the feedback position B1 corresponding to the first packet.
As shown in fig. 9, also taking the example of sequentially subtracting 1, after obtaining the feedback position B5 corresponding to the third packet, since the time slot before B5 is the time slot for downlink transmission, when determining the feedback position corresponding to the second packet by sequentially subtracting 1, it is necessary to continuously skip two time slots B4 and B3 for downlink transmission, and respectively take B2 and B1 as the feedback positions corresponding to the second packet and the first packet.
Further, not necessarily a numerical type of the received target parameter value. The data type of the target parameter value is indicated by second indication information;
wherein the data types include at least one of: numeric type, non-numeric type.
The second indication information is determined by at least one of:
a target indication field of the downlink control information; wherein the target indication field is used for indicating the data type of the target parameter value; the target indication field may be an additional indication field added in DCI;
target values of other indication fields in the downlink control information; wherein the target value is indicative of a data type of a target parameter value; the target indication field may also be a DCI existing indication field, and the data type of the target parameter value is indicated by a specific target value.
If there are a plurality of received target parameter values, the data type of each target parameter or the data type of a part of the target parameters may be indicated by the second indication information. The second indication information may also be determined by a target indication field of the downlink control information or a target value of another indication field in the downlink control information.
The data type of a part of the target parameter values may be a plurality of target parameter values connected to the received target parameter values, generally, a plurality of target parameter values are connected after the first target parameter value starts.
Therefore, in the feedback information sending method provided by the embodiment of the present application, when the feedback manner is that the received physical downlink shared channels are fed back at different times, the received physical downlink shared channels are grouped; according to the target parameter values received in the downlink control information and the corresponding relation between the target parameter values and each group, the feedback position corresponding to each group is determined, and various corresponding relations and determination methods of the feedback positions are provided, so that the terminal can flexibly select the method for determining the feedback position of each PDSCH according to the requirement under the condition that one downlink control information schedules a plurality of PDSCHs, the accurate transmission of the feedback information is ensured, and the transmission efficiency of data is improved.
It should be noted that, in the feedback information sending method provided in the embodiment of the present application, the execution main body may be a feedback information sending apparatus, or a control module in the feedback information sending apparatus for executing the feedback information sending method. In the embodiment of the present application, a method for a feedback information sending apparatus to execute feedback information sending is taken as an example, and an apparatus for sending feedback information provided in the embodiment of the present application is described.
