Below in conjunction with attached drawing, the technical scheme provided by various embodiments of the present application will be described in detail.
Fig. 1 is the embodiment flow chart of the method for the present invention pair.
The embodiment of the present application proposes a kind of release semi-persistent scheduling hybrid automatic repeat-request feedback method, includes:
Step 101 configures at least one semi-persistent scheduling, and high-level signaling configures at least one alternative collection, each alternative
Concentrating includes at least one chosen candidate value；
For example, configuring to N number of semi-persistent scheduling, N >=2, in high-level signaling, every 1 alternative collection is exclusively used in described in 1
Semi-persistent scheduling configuration；Alternatively, high-level signaling includes 1 alternative collection for being exclusively used in discharging N number of semi-persistent scheduling configuration.
For example, constituting the alternative collection by the value that high-level signaling " dl-DataToUL-ACK " is configured.
Step 102, Physical Downlink Control Channel include the instruction for discharging at least one semi-persistent scheduling configuration；
The network equipment is semi-statically configured by Physical Downlink Control Channel release.For example, the release half that the network equipment is sent
There are two types of formats for the Physical Downlink Control Channel of static configuration: DCI format 1_0 and DCI format1_1.Time slot (or son
Time slot) HARQ-ACK corresponding to the Physical Downlink Control Channel that is semi-statically configured of the release that sends in n is in time slot (or the period of the day from 11 p.m. to 1 a.m
Gap) n+k feedback, the value of k is by " PDSCH-to-HARQ-timing-indicator " or high-level signaling " dl- in DCI
DataToUL-ACK " is determined.
For example, the case where being semi-statically configured for the release sent with DCI format 1_0, DCI field include
" PDSCH-to-HARQ-timing-indicator ", is used to indicate the value of k, and indicated value corresponds in { 1,2,3,4,5,6,7,8 }
1.
Step 103 is indicated using one in whole chosen candidate values as response time, for indicating first time unit and the
Relative time locations between two time quantums；
In step 103, it is first determined one in N number of alternative collection configured for N number of semi-persistent scheduling is target
Alternative collection, alternatively, using 1 alternative collection for being exclusively used in discharging N number of semi-persistent scheduling configuration as target alternative collection.Again with institute
1 chosen candidate value for stating target alternative concentration is indicated as the response time.
The first time unit is the last symbol of the corresponding control resource set of the Physical Downlink Control Channel
The time quantum at place or the first time unit are referred to by time-domain resource allocation field in the Physical Downlink Control Channel
Show；
Second time quantum is for transmitting the HARQ-ACK information place for responding the Physical Downlink Control Channel
Time quantum；
The time quantum is time slot or sub-slots.
It, should if the target alternative collection only includes 1 chosen candidate value in any one embodiment of the application method
Chosen candidate value may be used as unique response time instruction.
For example, if the alternative collection that high-level signaling " dl-DataToUL-ACK " is configured only includes a value, DCI
It does not include " PDSCH-to-HARQ-timing-indicator " field in format 1_1, the value of k is " dl-DataToUL-
The value that ACK " is configured.
In any one embodiment of the application method, if the target alternative collection includes at least two chosen candidate values
When, it is indexed in the Physical Downlink Control Channel comprising chosen candidate value, when determining unique response for concentrating from target alternative
Between indicate.
For example, when being semi-statically configured with the release that DCI format 1_1 is sent, if high-level signaling " dl-DataToUL-
ACK " configures multiple values, then includes " PDSCH-to-HARQ-timing-indicator " field in DCI format 1_1, should
One in the multiple values of the alternative collection that the value of field instruction k is configured for " dl-DataToUL-ACK ".
1 is selected in N number of alternative collection and is used as target alternative collection, for example, the target alternative collection is the semi-static tune of k-th
The alternative collection of configuration is spent, wherein K is preset.
For another example the target alternative collection is the alternative collection of k-th semi-persistent scheduling configuration, controlled in the physical down
It include the instruction of K value in channel.
Alternatively, the target alternative collection is the alternative collection of k-th semi-persistent scheduling configuration, the k-th semi-persistent scheduling
The alternative collection of configuration includes the smallest chosen candidate value in the alternative collection of N number of semi-persistent scheduling configuration.
Alternatively, the target alternative collection is the alternative collection of k-th semi-persistent scheduling configuration, the k-th semi-persistent scheduling
The alternative collection of configuration includes maximum chosen candidate value in the alternative collection of N number of semi-persistent scheduling configuration.
Herein, 1≤K≤N.
Fig. 2 is the embodiment flow chart that the method for the present invention is used for terminal device.
Any one embodiment of the application method is used for terminal device comprising the steps of:
Step 201 configures at least one described semi-persistent scheduling, and high-level signaling configures at least one alternative collection, each
It include at least one chosen candidate value in alternative collection；
For example, described be semi-statically configured is N number of.It is semi-statically configured to each, the network equipment is set by RRC signaling to terminal
Standby configuration semi-persistent resource, for example, constituting the alternative collection by the value that high-level signaling " dl-DataToUL-ACK " is configured.
Step 202 receives Physical Downlink Control Channel, and the Physical Downlink Control Channel includes that discharge at least one half quiet
The instruction of state scheduling configuration；
In step 202, terminal device obtains Physical Downlink Control Channel, and the Physical Downlink Control Channel is for discharging half
Static scheduling configuration.
Terminal device reception is semi-statically configured, after determining that activation is semi-statically configured by reception Physical Downlink Control Channel,
Data are received in corresponding resource according to the semi-static period.If terminal device receives the network equipment and is controlled by physical down
Channel release is semi-statically configured parameter, then terminal device, which stops at, is semi-statically configured corresponding resource reception data.
Step 203 determines that one in whole chosen candidate values indicates as response time, for indicate first time unit and
Relative time locations between second time quantum；
The first time unit is the last symbol of the corresponding control resource set of the Physical Downlink Control Channel
The time quantum at place or the first time unit are referred to by time-domain resource allocation field in the Physical Downlink Control Channel
Show；Second time quantum, be for transmit where the HARQ-ACK information for responding the Physical Downlink Control Channel when
Between unit；The time quantum is time slot or sub-slots；
In step 203, the terminal device it needs to be determined that HARQ-ACK information feedback time.The terminal device root
Determine that object time, the object time are that the terminal device sends the physical down according to the Physical Downlink Control Channel
The time of the HARQ-ACK response message of control channel.
Terminal device selected target alternative collection in alternative collection, then 1 chosen candidate value is selected from target alternative concentration.Step
203A~B provides two embodiments:
Step 203A, the described Physical Downlink Control Channel includes the instruction for discharging N number of semi-persistent scheduling configuration, N >=2；It is high
In layer signaling, every 1 alternative collection is exclusively used in 1 semi-persistent scheduling configuration；It determines and is used for N number of semi-persistent scheduling
One in N number of alternative collection of configuration is target alternative collection；Using 1 chosen candidate value that the target alternative is concentrated as the response
Time instruction.
For example, the case where being semi-statically configured for the release sent with DCI format 1_1, if high-level signaling configures
Alternative collection as target alternative collection include multiple values, then include indication field in DCI format 1_1, which indicates k
One in multiple values that value is configured by high-level signaling；If the alternative collection of high-level signaling configuration is only matched as target alternative collection
A value is set, then does not need to include indication field in DCI format 1_1, response time indicates that (k) is the high-level signaling
The value configured.
Step 203B, the described Physical Downlink Control Channel includes the instruction for discharging N number of semi-persistent scheduling configuration, N >=2；It is high
Layer signaling includes 1 alternative collection for being exclusively used in discharging N number of semi-persistent scheduling configuration, as target alternative collection, with the mesh
1 chosen candidate value in mark alternative collection is indicated as the response time.
For example, if Physical Downlink Control Channel release N (N >=2) are a is semi-statically configured, and this N number of is semi-statically configured pair
" dl-DataToUL-ACK " configuration answered is different, then terminal device configures true according to preset second " dl-DataToUL-ACK "
It sets the goal the time.
According to the value that second " dl-DataToUL-ACK " is configured, and the N number of semi-static Physical Downlink Control Channel of release
In " PDSCH-to-HARQ-timing-indicator " field, terminal device can determine value k.Terminal device is according under physics
The value of time slot or sub-slots and k where the last symbol of corresponding control resource set (CORSET) of row control channel determines
The object time of corresponding HARQ-ACK feedback.Alternatively, terminal device distributes word according to time-domain resource in Physical Downlink Control Channel
The value of section instruction and k determine the object time of corresponding HARQ-ACK feedback.Second " dl-DataToUL-ACK " is independently of N number of
It is semi-statically configured, is exclusively used in terminal device and determines the feedback for discharging semi-static Physical Downlink Control Channel corresponding HARQ instance-ACK
Time.
Alternatively, determining value k according to the value that second " dl-DataToUL-ACK " is configured.Terminal device is according to physical down
The value of time slot or sub-slots and k where the last symbol of the corresponding control resource set of control channel determines corresponding HARQ-
The object time of ACK feedback.Alternatively, terminal device is according to the instruction of time-domain resource allocation field and k in Physical Downlink Control Channel
Value determine object time of corresponding HARQ-ACK feedback.Second " dl-DataToUL-ACK " is independently of N number of be semi-statically configured
, it is exclusively used in terminal device and determines the feedback time for discharging semi-static Physical Downlink Control Channel corresponding HARQ instance-ACK.
Step 204 sends the HARQ-ACK information in second time quantum.
Terminal device, which is sent, sends HARQ-ACK information for the semi-static Physical Downlink Control Channel of release.
If the Physical Downlink Control Channel information that the release that the network equipment is sent is semi-statically configured does not have in terminal
It is correctly received, which determines semi-persistent resource still according to the period that downlink is semi-statically configured, corresponding half
Static resource receives data.The unnecessary interference received between processing and up channel of terminal device is caused in this way, is influenced
System effectiveness.Therefore, it after terminal device receives the Physical Downlink Control Channel that release is semi-statically configured, is sent to the network equipment
For the ACK information of the Physical Downlink Control Channel.
Fig. 3 is to indicate to determine the second time quantum schematic diagram according to first time unit and response time.
When the value that " dl-DataToUL-ACK " is configured is sub-slots, DCI field " PDSCH-to-HARQ-timing-
Indicator ", or the value of k that " dl-DataToUL-ACK " is configured refer between the first sub-slots and the second sub-slots
Number of time slots.First sub-slots refer to that the Physical Downlink Control Channel that release is semi-statically configured corresponds to control resource set most
Sub-slots where the latter symbol.Alternatively, the first sub-slots refer to the Physical Downlink Control Channel that release is semi-statically configured
Sub-slots where the last symbol of corresponding control resource set.
For the Physical Downlink Control Channel that release is semi-statically configured, do not need to send out according to the configuration of sub-slots
It send.Such as the time span of the corresponding control resource set of Physical Downlink Control Channel can be greater than the length of sub-slots, under physics
The time of the corresponding control resource set of row control channel is also possible to the boundary across between sub-slots.HARQ- based on sub-slots
ACK feedback is not meant to that downlink transfer is also based on sub-slots.First sub-slots mentioned here, which are that release is semi-static, matches
Sub-slots where the last symbol of the corresponding control resource set of the Physical Downlink Control Channel set.Downlink sub-slots are bases
The virtual sub-slots of the corresponding configuration of the sub-slots of ascending HARQ-ACK feedback.By taking 1 sub-slots includes 7 symbols as an example, use
It is located at the sub-slots n_1 in time slot n in the corresponding control resource set of Physical Downlink Control Channel that release is semi-statically configured.That
, the k=3 corresponding object time is the sub-slots n+1_2 in time slot n+1.
Alternatively, if terminal device receives the network equipment and is semi-statically configured by Physical Downlink Control Channel release,
Terminal device, which stops at, to be semi-statically configured corresponding resource reception or sends data.Under the physics that release downlink is semi-statically configured
Row control channel is scrambled using CS-RNTI.And discharge identification field carrying in the Physical Downlink Control Channel being semi-statically configured
Information be presupposed information.For example, as shown in the table, identification information includes HARQ process number, redundancy versions, modulating-coding
Scheme, frequency domain resource distribution.
The Physical Downlink Control Channel being semi-statically configured is discharged in addition to above-mentioned identification field, other fields are matched for semi-static
If setting the effect without other instructions, the position of determining object time can be used as.If Physical Downlink Control Channel includes
Discharge the instruction of at least one semi-persistent scheduling configuration；Each semi-persistent scheduling is configured, it is standby by high-level signaling configuration one
Selected works.One alternative collection includes at least one chosen candidate value, for indicating opposite between first time unit and the second time quantum
Time location.Second time quantum be for transmit where the HARQ-ACK information for responding the Physical Downlink Control Channel when
Between unit.Preferably, with the time quantum of the time-domain resource allocation field instruction first time in Physical Downlink Control Channel.It is right
The time quantum of first time how is indicated in time-domain resource allocation field, and the present invention does not limit particularly.For example, may be used
With the option of time quantum where presetting a variety of first time units, indicated by time-domain resource allocation field it is preset it is a variety of in
It is a kind of.For example, the time-domain resource allocation field for discharging the Physical Downlink Control Channel being semi-statically configured has 4 bit informations,
It then can at most indicate preset 16 kinds of first time units.Alternatively, can also be with preset time resource length and non-temporal list
Member, but resource longer than time quantum or short.For example time quantum is sub-slots, a sub-slots include that 7 symbols are long
Degree.But time-domain resource distribution field indicating length be the time-domain resource of 9 symbols or indicating length be 4 to symbol when
Domain resource, it is in this case, single with the time where the last symbol of the time-domain resource of time domain resource allocation field instruction
Member is used as first time unit.
Fig. 4 is that response time is selected to indicate to determine the second time quantum schematic diagram in multiple alternative collections.
Assuming that sub-slots are configured to include 2 sub-slots in 1 time slot, each sub-slots include 7 symbols.Illustrate N=
