The network device may be a base station, and the base station may include various macro base stations, micro base stations, relay stations, access points, and the like.

For example, in an LTE network, called an Evolved Node B (eNB or eNodeB), in a third generation (3 rd generation,3 g) network, called a Node B (Node B), or a network device in a subsequent Evolved communication system, etc., although the terms are not limiting.
As shown in fig. 1, an embodiment of the present invention provides a transmission method 100 of HARQ-ACK feedback information, which may be performed by a terminal device, in other words, the method may be performed by software or hardware installed in the terminal device, and the method includes the following steps:
s102: and if the transmission direction of the symbol set of the time slot in which the first resource of the physical channel is positioned conflicts with the transmission direction of the symbol set of the target time slot, determining the target available resource behind the first resource.
The HARQ-ACK feedback information corresponds to a PDSCH configured by SPS; the physical channel is used for carrying HARQ-ACK feedback information.
The first resource may be determined by the terminal device based on a parameter (dl-DataToUL-ACK, abbreviated as K1) configured by a higher layer. Specifically, as shown in fig. 2, the resource location of the PDSCH received by the terminal device is time slot n, and based on the parameter K1=3, the determined first resource is time slot n +3.
It should be noted that, in each embodiment of this specification, a resource, such as a first resource, may refer to a time unit, such as a slot (slot), a symbol, and for convenience of understanding, in the following embodiments, a slot is often used as an example for description.
The transmission direction of the symbol set of the slot (referred to as the transmission direction of the symbol set of the slot for short) may include Uplink (UL), downlink (DL), or flexible (flexible), etc. The transmission direction of the symbol set of the target time slot may be the transmission direction of the symbol set of the time slot that the terminal device can use to send HARQ-ACK feedback information. Optionally, the transmission direction of the symbol set of the target timeslot is uplink; of course, in other embodiments, the transmission direction of the symbol set of the target slot may also include flexibility.
The symbol set mentioned here may specifically refer to symbols occupied by the physical channel in one slot, for example, one slot includes 14 symbols, the physical channel occupies 9 th to 14 th symbols, and the symbol set mentioned here may be the 9 th to 14 th symbols mentioned above.
The transmission direction of the symbol set of the time slot in which the first resource is located and the transmission direction of the symbol set of the target time slot conflict with each other, which may be that the transmission direction of the symbol set of the time slot in which the first resource is located and the transmission direction of the symbol set of the target time slot are not the same. Specifically, for example, the transmission direction of the symbol set of the target timeslot is uplink, and the transmission direction of the symbol set of the timeslot in which the first resource is located is downlink or flexible.
In other embodiments, there is also a case that the transmission direction of the symbol set of the time slot in which the first resource is located does not conflict with the transmission direction of the symbol set of the target time slot, that is, the transmission direction of the symbol set of the time slot in which the first resource is located is consistent with the transmission direction of the symbol set of the target time slot. Specifically, for example, the transmission direction of the symbol set of the target timeslot is uplink, and the transmission direction of the symbol set of the timeslot in which the first resource is located is also uplink. In this embodiment, the terminal device may send the physical channel of the HARQ-ACK feedback information directly over the first resource bearer.
The Physical Channel is used for carrying HARQ-ACK feedback information, and may be a Physical Uplink Control Channel (PUCCH) or a Physical Uplink Shared Channel (PUSCH).
In the example shown in fig. 2, the first resource is a slot n +3, the transmission direction of the symbol set of the slot n +3 is downlink, and the terminal device obviously cannot transmit uplink information (HARQ-ACK feedback information) through the first resource, so that the terminal device may determine an available resource after the first resource.
In fig. 2, slot n +4 is a self-contained slot, assuming no available slot; the time slot n +5 is an uplink time slot and is an available time slot; slot n +6 is also an uplink slot and is also an available slot.
In some embodiments, resources that collide with the transmission direction of the symbol set of the target slot may be referred to as unavailable resources, and resources that do not collide with the transmission direction of the symbol set of the target slot may be referred to as available resources. When the first resource collides with the transmission direction of the symbol set of the target slot, that is, the first resource is an unavailable resource, the terminal device may determine the first available resource after the first resource as the target available resource, for example, the slot n +5 is determined as the target available slot in fig. 2.
The target available resource mentioned in this specification may be an available resource for transmitting a physical channel carrying HARQ-ACK feedback information. Optionally, the transmission direction of the symbol set of the slot of the target available resource is consistent with the transmission direction of the symbol set of the target slot, and both are uplink resources.
S104: and sending a physical channel carrying HARQ-ACK feedback information through the target available resources.
As shown in fig. 2, the target available resource is a time slot n +5, and the terminal device may send a physical channel carrying HARQ-ACK feedback information through a corresponding symbol in the time slot n +5.
In the embodiment of the invention, if the transmission direction of the symbol set of the time slot in which the resource of the physical channel bearing the HARQ-ACK feedback information is located conflicts with the transmission direction of the symbol set of the target time slot, the terminal equipment can determine the available resource behind the resource and send the physical channel bearing the HARQ-ACK feedback information through the available resource. The embodiment of the invention provides a solution for a processing mechanism of the terminal equipment when the resource conflicts, which is convenient for realizing the timely transmission of the HARQ-ACK feedback information and improving the communication effectiveness.
The embodiment of the invention is particularly suitable for a scene that the resource fed back by the HARQ-ACK is easy to conflict under the condition that a plurality of SPS configurations are configured in an NR system, in particular to the condition of time division duplex TDD time slot format configuration of downlink heavy service.
In the above-mentioned S102 of the embodiment 100, referring to determining the target available resource after the first resource, in an implementation, the terminal device may sequentially determine the resources after the first resource until the available resource is found. For example, in fig. 2, the first resource is a time slot n +3, the terminal device first determines whether the time slot n +4 is an available time slot, in fig. 2, the time slot n +4 is a self-contained time slot, and if it is not an available time slot, it continues to determine whether the time slot n +5 is an available time slot, in fig. 2, the time slot n +5 is an available time slot, and the terminal device may determine the time slot n +5 as a target available time slot (i.e., the aforementioned target available resource).
In another implementation, the reference in S102 of the embodiment 100 to the target available resource after the first resource is determined may specifically be: determining a target available resource behind the first resource according to the first parameter in the feedback timing set; wherein the feedback timing set is a high level configuration.
The feedback timing set may also be referred to as a set of HARQ-ACK timing values, where the HARQ-ACK timing value is a parameter in the set, and the first parameter is one HARQ-ACK timing value in the set of HARQ-ACK timing values. In this embodiment, the network device may configure a dedicated HARQ-ACK timing value set for the terminal device through RRC signaling, where the set includes multiple HARQ-ACK timing values, which are referred to as K1 values, and K1 may be a slot unit. Therefore, this embodiment may also be referred to as feedback timing set corresponding to the PDSCH of the SPS configuration.
Optionally, before S102 of embodiment 100, the terminal device may further determine, according to the second parameter in the feedback timing set, the first resource of the physical channel carrying the HARQ-ACK feedback information.
The second parameter is one HARQ-ACK timing value of the set of HARQ-ACK timing values. In one example, the set of feedback timings is {1,2,3,4,5}, the second parameter is 3, and the first parameter may be greater than the second parameter, e.g., the first parameter is 4 or 5.
In this embodiment, since the first parameter is greater than the second parameter, sufficient processing time (i.e., time for processing the PDSCH) is provided for the terminal device, and it is avoided that the terminal device does not complete processing of the PDSCH when the determined target available resource is used, which is convenient for implementing effective transmission of HARQ-ACK feedback information, and improves communication effectiveness.
Considering that the number of the first parameters in the feedback timing set is larger than the second parameters, in an embodiment, the above-mentioned determining the target available resources after the first resources according to the first parameters in the feedback timing set includes: and sequentially determining the transmission direction of the symbol set of the time slot of the resource corresponding to the first parameter according to the sequence of the first parameters until determining the available resource of the physical channel carrying the HARQ-ACK feedback information, wherein the available resource does not conflict with the transmission direction of the symbol set of the target time slot.
Optionally, in this embodiment, it may be sequentially determined whether the transmission direction of the symbol set of the time slot in which the resource corresponding to the first parameter is located conflicts with the transmission direction of the symbol set of the target time slot until determining the available resource of the physical channel carrying the HARQ-ACK feedback information.
Specifically, for example, if the transmission direction of the symbol set of the time slot in which the resource corresponding to a certain first parameter is located is the same as the transmission direction of the symbol set of the target time slot, it is determined that the resource corresponding to the first parameter is the target available resource.
Optionally, before the embodiment is performed, the terminal device may further determine an ordering of the plurality of first parameters.
Optionally, the ordering of the plurality of first parameters may be from small to large. Specifically, for this embodiment, the feedback timing set is {1,2,3,4,5}, the second parameter is 3, and the first parameter includes 4,5. The first parameter is ordered 4 before 5, that is, the transmission direction of the symbol set of the time slot in which the resource corresponding to the first parameter 4 is located is determined first:
if the resource corresponding to the first parameter 4 is an available resource, directly determining the resource corresponding to the first parameter 4 as a target available resource;
if the resource corresponding to the first parameter 4 is an unavailable resource, determining the resource corresponding to the first parameter 5; if the resource corresponding to the first parameter 5 is an available resource, determining the resource corresponding to the first parameter 5 as a target available resource;
if the resource corresponding to the first parameter 5 is an unavailable resource, the terminal device may also discard the HARQ-ACK feedback information, which will form another embodiment of the present invention, that is:
and if the available resources of the physical channel carrying the HARQ-ACK feedback information do not exist after the first resources are determined according to a plurality of first parameters (namely parameters larger than the second parameters) in the feedback timing set, discarding the HARQ-ACK feedback information.
Optionally, the physical channel mentioned in S104 of the foregoing embodiment 100 for transmitting (carrying HARQ-ACK feedback information) through the target available resource includes: and if a Physical Uplink Control Channel (PUCCH) or a Physical Uplink Shared Channel (PUSCH) in the target available resource is not scheduled or configured to send Uplink Control Information (UCI), sending the HARQ-ACK feedback Information through the PUCCH or sending the HARQ-ACK feedback Information through the PUSCH. The PUCCH or PUSCH in this embodiment may be a channel resource configured by the network device for transmitting HARQ-ACK feedback information.
Optionally, the sending the physical channel through the target available resource mentioned in S104 of the foregoing embodiment 100 includes: and if the PUCCH or PUSCH in the target available resource is scheduled or configured to send UCI, multiplexing the HARQ-ACK feedback information and the UCI, and sending the multiplexed information through the PUCCH or PUSCH. The PUCCH or PUSCH in this embodiment may be a channel resource configured or scheduled by the network device for transmitting HARQ-ACK feedback information. The embodiment multiplexes a plurality of information, which is convenient for improving the utilization rate of resources.
In order to describe the transmission method of the HARQ-ACK feedback information in detail, several specific embodiments are described below.
Example one
As shown in fig. 2, assume that the network device configures PDSCH-to-HARQ-ACK feedback timing K1 (dl-DataToUL-ACK) for SPS configuration 1 to have a value of 3.
The time when the terminal device receives the PDSCH is time slot n, and the first time slot determined according to K1=3 is time slot 3, but the network configures a time slot format, the transmission direction of time slot n +3 is downlink, and the time slot cannot be used for HARQ-ACK feedback.
If the HARQ-ACK feedback information of the SPS configuration 1 is discarded, the network device does not know whether the terminal device correctly receives the SPS service, and the network device needs to dynamically schedule the SPS service to ensure the reliability of transmission, but this wastes the resource utilization rate of the system.
This embodiment thus allows the terminal device to defer the HARQ-ACK bit of SPS configuration 1 to the next available uplink slot for transmission, e.g., to slot n +5 in fig. 2.
The embodiment of the invention provides a solution for a processing mechanism of the terminal equipment when the resource conflicts, which is convenient for realizing the effective transmission of the HARQ-ACK feedback information, is convenient for saving the resource utilization rate of the system and improving the communication effectiveness.
Example two
In this embodiment, the feedback timing set configured by the network device for the terminal device includes 4 elements (or parameters), which are 2,3,4,5 respectively.
As shown in fig. 2, assume that the network device configures PDSCH-to-HARQ-ACK feedback timing K1 (dl-DataToUL-ACK) for SPS configuration 1 to have a value of 3.
The time when the terminal device receives the PDSCH is time slot n, and the first time slot determined according to K1=3 is time slot 3, but the network configures a time slot format, the transmission direction of time slot n +3 is downlink, and the time slot cannot be used for HARQ-ACK feedback.
In this embodiment, the terminal device arranges the parameters in the feedback timing set in order from small to large, and then sequentially checks whether the timeslot corresponding to the parameters 4 and 5 (a value greater than the configured feedback timing, that is, 3) is an available timeslot (UL timeslot).
Feeding back HARQ-ACK feedback information if the HARQ-ACK feedback information is available; if none is available, it means that the parameter values in the feedback timing set do not meet the requirements, and the HARQ-ACK feedback information for the PDSCH of this SPS configuration 1 will be discarded.
In this embodiment, the timeslot corresponding to parameter 4 is a self-contained timeslot, which is assumed not to be an available timeslot; the time slot corresponding to the parameter 5 is an uplink time slot and is an available time slot, and therefore, the terminal device sends HARQ-ACK feedback information through the time slot 5.
This embodiment may look up in a predefined order, e.g., in increasing order of parameters in the feedback timing set, and then starting backwards from the value of the configured feedback timing (e.g., parameter 3), and then looking from small to large until available uplink resources are found.
In this embodiment, the value of the feedback timing configured by the network device is 3, and the terminal device only detects whether the timeslot corresponding to the parameter greater than 3 in the feedback timing set is an available timeslot, but does not detect the timeslot corresponding to the parameter less than 3, which provides sufficient processing time (i.e., time for processing the PDSCH) for the terminal device, so as to implement effective transmission of HARQ-ACK feedback information and improve communication effectiveness.
Meanwhile, in order to ensure that the terminal device and the network device have the same understanding, the delayed time slot only uses the uplink time slot, and does not use the flexible time slot (or symbol).
Optionally, in the embodiment shown in fig. 2, there is also a case that the transmission direction of the symbol set of the time slot in which the first resource is located does not conflict with the transmission direction of the symbol set of the target time slot, that is, the transmission direction of the symbol set of the time slot of the first resource is consistent with the transmission direction of the symbol set of the target time slot.
As shown in fig. 2, assume that the network device configures PDSCH-to-HARQ-ACK feedback timing K1 (dl-DataToUL-ACK) for SPS configuration 2 to have a value of 4.
