Detailed Description
The term "and/or" in the embodiments of the present invention describes an association relationship of associated objects, and indicates that three relationships may exist, for example, a and/or B may indicate: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
In the embodiments of the present application, the term "plurality" means two or more, and other terms are similar thereto.
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
It should be appreciated that flexible timing relationships are supported in the 5G new air interface (NR). For a Physical Uplink Control Channel (PUCCH), a corresponding Physical Downlink Control Channel (PDCCH) indicates a scheduling timing relationship (HARQ timing, i.e., K1) between a Physical Downlink Shared Channel (PDSCH) and the PUCCH. For a Physical Uplink Shared Channel (PUSCH), a PDCCH carrying Scheduling information thereof indicates a Scheduling timing relationship (K2) between the PUSCH and the PDCCH. Specifically, the PDCCH uses a feedback timing indication field from the PDSCH in the Downlink Control Information (DCI) to a Hybrid Automatic Repeat request-ACKnowledgement (HARQ-ACK) to indicate the number of time slots K1 from the end of the PDSCH to the start of the HARQ-ACK, that is, the PDSCH transmission at the end position in time slot n performs HARQ-ACK transmission in time slot n + K1. The full set of K1 is {0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15}, and is typically allocated to the terminal for up to 8 values. The value of K1 is in units of slots, i.e., K1=1 denotes an interval of 1 slot. K1=0 corresponds to the last PUCCH slot overlapping the received PDSCH or PDCCH indicating the SPS PDSCH release.
A Time Domain Resource Allocation (TDRA) indication field in the DCI indicates a time slot offset K2 between a time slot in which the PUSCH is located and a time slot in which the DCI is located, and the DCI of time slot n indicates that the PUSCH transmission is performed in time slot n + K2. The full set of K2 is {0,1,2,3,4, \8230; \8230, 32}, and is typically configured to the terminal by a TDRA table with a maximum of 16 values. The value of K2 is in units of slots, i.e., K2=1 denotes an interval of 1 slot. K2=0 corresponds to the first PUSCH slot overlapping the slot in which the received PDCCH is located.
The embodiment of the invention provides a transmission processing method and device. The method and the device are based on the same application concept, and because the principles of solving the problems of the method and the device are similar, the implementation of the device and the method can be mutually referred, and repeated parts are not described again.
As shown in fig. 1, a transmission processing method provided in an embodiment of the present invention includes:
102, the terminal determines a corresponding uplink transmission position according to the first configuration information and/or the second configuration information;
wherein the first configuration information includes a plurality of K1 s, an
The time unit of each K1 is a time slot, and the number of the configured K1 is larger than a first value; or each time unit of K1 is one or more of preset time units;
the second configuration information includes a plurality of K2's, an
Each time unit of K2 is a time slot, and the number of the configured K2 is larger than a second value; alternatively, the time unit of each K2 is one or more of the preset time units.
Here, the first value is a preset number threshold of K1, such as 8; the second value is a preset number threshold of K2, such as 16. That is, on the one hand, the number of the configured plural K1 and/or K2 increases when the time units thereof are all time slots, and the range of the selectable value is expanded. On the other hand, for the configured multiple K1 and/or K2, the time unit of each K1 and/or K2 is one or more of the preset time units, the range of the selectable value is also expanded, and the time range of the selectable value is more flexible. Therefore, the determined uplink transmission position can be better covered in the corresponding service beam scanning period, and the transmission quality is ensured.
Optionally, the preset time unit comprises at least one of:
milliseconds;
a beam period;
a time slot.
That is, the 1 time unit may be a combination of any one or more of the following: milliseconds, beam period, time slots. Wherein the 1 time unit is not limited to one or more of 1 millisecond, 1 beam period, and 1 time slot.
Taking the first configuration information as an example, if the first configuration information includes a plurality of K1, the following are respectively: k11 K11, K12, and K13 may be the same or different time units, and may be one or more of the preset time units, for example, K11 is 5ms +1sl, K12 is 1 beam period, and K13 is 1 beam period +2sl. Where sl represents a slot unit (slot).
Certainly, when the first configuration information includes that the plurality of K1 are all the same preset time unit, and the time unit is a time slot, the number of K1 in the plurality of K1 is greater than the first value; similarly, the second configuration information includes that the plurality of K2 are all the same preset time unit, and when the time unit is a time slot, the number of K2 in the plurality of K2 is greater than the second value.
Optionally, in a case that the time unit of each K1 is one or more of preset time units, the plurality of K1 belongs to the same set; alternatively, each K1 is assigned to a different set, and the time unit of K1 in the different sets is different.
That is, for the first configuration information including a plurality of K1, in the case that the time unit of each K1 is one or more of the preset time units, the plurality of K1 may belong to one set, and it may also be understood that the first configuration information configures one K1 set. The time unit corresponding to the K1 set may be a combination of any one of the following: x1 milliseconds, where X1 is an integer greater than or equal to 1; y1 beam periods, wherein Y1 is an integer greater than or equal to 1; z1 time slots, wherein Z1 is an integer greater than or equal to 1.
Alternatively, the plurality of K1 s correspond to different K1 sets, different K1 sets correspond to different time units, and each K1 is determined by a plurality of K1 sets, which may be understood as that the first configuration information configures a plurality of K1 sets. The time unit corresponding to each K1 set may be any one of the following: x2 milliseconds, where X2 is an integer greater than or equal to 0; y2 beam periods, wherein Y2 is an integer greater than or equal to 0; z2 time slots, where Z2 is an integer greater than or equal to 0. Here, the values in each K1 set are only partial K1, and the value of K1 requires multiple K1 sets to determine. For example, M K1 sets are configured to correspond to different time units respectively, and the value of one K1 is equal to K1_1+ K1_2+ \8230 ++ K1_ M, wherein K1_1, K1_2, \8230; + K1_ M is the value of the portion K1 corresponding to the K1 set of the different time units.
In this embodiment, the configuration of K2 allows for implementation of a TDRA table, and optionally, in the case that the time unit of each K2 is one or more of preset time units, the plurality of K2 belongs to the same set.
That is, the second configuration information includes a plurality of K2, and in the case that the time unit of each K2 is one or more of the preset time units, the plurality of K2 may belong to one set, or it may be understood that the second configuration information configures one K2 set. The time unit corresponding to the K2 set may be a combination of any one of the following: x3 milliseconds, where X3 is an integer greater than or equal to 1; y3 beam periods, wherein Y3 is an integer greater than or equal to 1; z3 time slots, where Z3 is an integer greater than or equal to 1.
It should be noted that, after configuration is completed, on one hand, the terminal can determine currently applicable K1 and/or K2 based on the configuration; on the other hand, after the configuration, the network side device may further indicate currently applicable K1 and/or K2 through DCI. As such, in response to the indication of the network-side device, optionally before step 201, the method further includes:
the terminal receives downlink control information DCI, wherein the DCI comprises first indication information of K1 or second indication information of K2.
Thus, the terminal can determine the currently applicable K1 or K2 through the received DCI. The first indication information is K1 indication domain information in DCI for scheduling PDSCH, and the second indication information is TDRA indication domain information in DCI for scheduling PUSCH.
Optionally, when the time unit of each K1 included in the first configuration information is a time slot, the size of the first indication information is determined by the number of configured K1;
under the condition that the time unit of each K1 included in the first configuration information is one or more of preset time units, if the plurality of K1 belong to the same set, the size of the first indication information is determined by the number of configured K1; and if each K1 belongs to different sets, jointly determining the number of the configured K1 and the number of the sets.
If the time unit of each configured K1 of the first configuration information is a time slot, and the number P of configured K1 is greater than a first value, the size of the first indication information may be ceil (log 2 (P)). If 16K 1 are configured, and the time unit of each K1 is a time slot, the size (i.e., the number of bits) of the first indication information is 4 bits.
If the first configuration information configures each time unit of K1 as one or more of the preset time units, and all configured K1 (Q K1) belong to the same set, the size of the first indication information may be ceil (log 2 (Q)). For example, if 1K 1 set is configured to include 16K 1, and the time unit of each K1 of the K1 set is one or more of the preset time units, the size (i.e., the number of bits) of the first indication information is 4 bits.
If the time unit of each K1 configured by the first configuration information is one or more of the preset time units, and each configured K1 belongs to different sets (M K1 sets), the time units of the K1 in the different sets are different, and the number of the K1 values in each K1 set is I 1 ,I 2 ,……,I M Then the size of the first indication information may be ceil (log 2 (I) 1 )+log2(I 2 )+……+log2(I M )). For example, 2K 1 sets are configured, a first K1 set corresponds to a preset time unit as a timeslot, the first K1 set includes 2 values, a second K1 set corresponds to a preset time unit as milliseconds, and the second K1 set includes 4 values, then the size (i.e., the bit number) of the first indication information may be 3 (i.e., 1+ 2) bits, i.e., 1 bit indicates that the first K1 set corresponds to a predetermined time unitThe value, 2 bits, indicates the value corresponding to the second set of K1.
In this embodiment, optionally, step 102 includes:
under the condition that the DCI comprises the first indication information, the terminal determines a target K1 according to the first indication information and the first configuration information;
and the terminal determines the position of the PUCCH according to the target K1, the first offset value and the position of the PDSCH.
For the received DCI including the first indication information, the first indication information and the first configuration information are combined to determine a target K1, and then, the position of the corresponding PUCCH is determined according to the target K1, the first offset value, and the position of the PDSCH. Here, the first offset value K-offset is a pre-configured compensation value, such as a fixed offset length configured to the terminal by the base station through higher layer signaling. For feedback timing in satellite communications, K-offset is also denoted as TA-offset.
Of course, if the first offset value is not considered (i.e. the first offset value is 0), after the target K1 is determined, the position of the corresponding PUCCH may be determined directly from the positions of the target K1 and the PDSCH.
In the following, the application of the embodiment of the present application is described with reference to specific scenarios:
as shown in fig. 2, the transmitted subcarriers are spaced 120khz apart and contain 8 slots in 1 ms.

a seventh mode, a base station configures two K1 sets for a terminal, a PDSCH transmitted in a slot n determines a HARQ-ACK feedback slot based on n + K-offset + K1_1+ K1 \ 2, where the value of K-offset is 80 slots, a first configured K1 set is {5ms,6ms,7ms,8ms,20ms,21ms,22ms,23ms }, a second configured K1 set is {0sl,1sl,2sl,3sl }, and the size of first indication information (K1 indication domain information bit number) in DCI is 5 bits, where the first three bits are used to indicate a value in the first K1 set, and the last two bits are used to indicate a value in the second K1 set;
and determining a HARQ-ACK feedback time slot based on the time slot n + K1_1+ K1 \ u 2 by the PDSCH transmitted in the time slot n, wherein the base station configures a first K1 set of {10ms, 111ms, 12ms and 13ms } and a second K1 set of {0sl,1sl,2sl and 3sl } for the terminal, and the size of first indication information (K1 indicates the domain information bit number) in the DCI is 4 bits, wherein the first two bits are used for indicating the value in the first K1 set, and the last two bits are used for indicating the value in the second K1 set.
In the first and second modes, the time unit of each K1 configured corresponding to the first configuration information is a time slot, and the number of configured K1 is greater than the first value; a third mode and a sixth mode, where the time unit of each K1 is configured to correspond to the first configuration information, and all configured K1 belongs to the same set; in the seventh and eighth modes, the time unit of each K1 is configured to correspond to the first configuration information, and the configured K1 belongs to different sets, and the time units of K1 in different sets are different.
In this embodiment, for K2, it is configured in each row of the TDRA, so specifically, the configuration of K2 is implemented by extending the number of K2 for K2 whose time units are time slots when the base station configures the TDRA table; the same or different preset time units may also be configured for the K2 value in each row, for example, the K2 value in the first row in the TDRA table is configured to be 5ms, the K2 value in the second row is 6ms, the K2 value in the third row is 20ms, the K2 value in the fourth row is 20ms +1sl, and the like, and the specific parameters are configured through the base station. If the second indication information in the DCI indicates K2, the indication is performed by using the TDRA, which is not described herein again.
Optionally, step 102 comprises:
under the condition that the DCI comprises the second indication information, the terminal determines a target K2 according to the second indication information and the second configuration information;
and the terminal determines the position of the PUSCH according to the target K2, the second deviation value and the position of the PDCCH.
For the received DCI including the second indication information, the second indication information and the second configuration information are combined to determine a target K2, and then the position of the corresponding PUSCH is determined according to the target K2, the second offset value and the position of the PDCCH. Here, the second offset value K-offset is a pre-configured compensation value, such as a fixed offset length configured by the base station to the terminal through higher layer signaling. For feedback timing in satellite communications, K-offset is also denoted as TA-offset.
Of course, if the second offset value is not considered (i.e. the second offset value is 0), after the target K2 is determined, the corresponding PUSCH position may be determined directly from the positions of the target K2 and the PDCCH.
For example, for a PDCCH transmitted in slot n, slot n + K-offset + K2 is a PUSCH transmission slot, or a PUSCH transmission slot is determined based on n + K2.
It should be noted that, in the embodiment of the present invention, when determining the HARQ-ACK feedback slot or the PUSCH transmission slot, the units of the slots n, K-offset, K1, and K2 may be different, and therefore, the slots need to be converted into the same time unit. For the HARQ-ACK feedback sequence, converting into a PUCCH time slot unit; for PUSCH scheduling timing, the slot units of the PUSCH may all be converted. For example, when determining the HARQ-ACK feedback timing, the time unit of K-offset is millisecond and the time unit of K1 is slot for PDSCH whose end position is transmitted in uplink slot n, and the feedback slot of HARQ-ACK is n + K-offset x2 u + K1. For another example, when determining the HARQ-ACK feedback timing, for the PDSCH whose end position is transmitted in uplink slot n, the time unit of K1 is the beam period (10 ms), and then the feedback slot of HARQ-ACK is n + K1 × 10 × 2 u . In the above example, u is a parameter number corresponding to the uplink SCS; for example, a u value of 3 for 120 kHz.
To sum up, the method of the embodiment of the present invention can support indicating an effective HARQ-ACK feedback slot or PUSCH transmission slot when a service beam is periodically switched among different wave positions in satellite communication, and implement transmission timing indication in a time period covering a current wave position within a service beam scanning period.
