Description

Uplink time domain resource scheduling method and network equipment

Technical Field

The present application relates to the field of communications technologies, and in particular, to a method and a network device for scheduling uplink time domain resources.

Background

In a wireless communication system, a terminal device may perform uplink transmission using a time-frequency resource allocated to the terminal device by a network device, where the time-frequency resource includes a time-domain resource and a frequency-domain resource. Before the terminal equipment performs uplink transmission by using the time-frequency resources allocated by the network equipment, the network equipment is required to schedule and allocate the time-frequency resources, and the network equipment allocates the time-frequency resources and the frequency-domain resources to the terminal equipment through time-domain scheduling and frequency-domain scheduling respectively.

In the New Radio (NR) technology, there are two time domain scheduling modes, one is a slot-based time domain scheduling mode, that is, one slot transmits scheduling information once, and the number of symbols included in one slot is 14; the other is a time domain scheduling mode based on a micro-slot (mini-slot), namely, scheduling information is sent for multiple times in one slot, and the number of symbols contained in one mini-slot is 1-13. The scheduling Information sent by the network device includes an indication of an uplink time domain resource allocated to the terminal, and the scheduling Information needs to indicate a starting symbol of the time domain resource and a number of symbols corresponding to the time domain resource. In the current NR technology, combination parameters among a starting symbol, a symbol number, and a time domain scheduling manner in uplink time domain resource allocation are not yet determined, and a value range (1 to 14) of the starting symbol and a value range (1 to 14) of the symbol number are large, if the starting symbol and the symbol number in two value ranges are combined in a one-to-one correspondence manner, a large number of combination parameters are formed, so that a large number of bits are required for indicating the combination parameters, and signaling overhead is large.

In one possible design, in a case that the time domain scheduling manner configured for the terminal device is a micro-slot based time domain scheduling manner, the target number of symbols in the set of numbers of symbols is greater than or equal to 1, and is less than or equal to a difference between a total number of symbols included in the slot and a number of second symbols in the slot before a target starting symbol in the set of starting symbols, and is less than or equal to 13.

Detailed Description

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.

Before introducing the scheme of the present application, a combination situation among the starting symbol, the number of symbols, and a time domain scheduling manner, which is formed according to the original value range of the starting symbol and the original value range of the number of symbols, is introduced. The combination of the initial symbol count and initial symbol count formed from the initial symbol count and initial symbol count ranges is shown in table 1:

initial symbol	Number of symbols
		1	1，2，3，4，…，14
2	1，2，3，4，…，13
		3	1，2，3，4，…，12
…	1, 2, 3, 4, …, 15-start symbol
		14	1

TABLE 1

As can be seen from table 1, in the combination of the start symbol and the number of symbols, one start symbol may correspond to 14 kinds of symbol numbers, and the combination of the start symbol and the number of symbols is 14 × 15/2=105, and if all 105 combinations are indicated by the time domain resource indication, the time domain resource indication requires 7 bits.

Further, the combination of the starting symbol, the number of symbols, and the time-domain scheduling mode is shown in table 2, assuming that a represents the time-domain scheduling mode based on the time slot, and B represents the time-domain scheduling mode based on the micro-slot:

time domain scheduling mode	Initial symbol	Number of symbols
			A	1	1，2，3，4，…，14
A	2	1，2，3，4，…，13
			…	…	1, 2, 3, 4, …, 15-start symbol
A	14	1
			B	1	1，2，3，4，…，14
B	2	1，2，3，4，…，13
			…	…	1, 2, 3, 4, …, 15-start symbol
B	14	1

TABLE 2

The combination formed by the starting symbol, the number of symbols and the time domain scheduling mode is 105 × 2=210, and if the time domain resource indication further needs to indicate that the time domain resource is the time domain resource allocated based on which time domain scheduling mode, the time domain resource indication needs to have the bit number of 8.

As can be seen from tables 1 and 2, the combination of the initial symbol, the number of symbols, and the time domain scheduling manner formed according to the original value range of the initial symbol and the original value range of the number of symbols is more, the number of bits required for time domain resource indication is more, and the signaling overhead is large.

According to the scheme, the value range of the initial symbol and the value range of the symbol number of the uplink time domain resource are limited, unnecessary combinations are eliminated, the combinations among the initial symbol, the symbol number and the time domain scheduling mode are reduced, the number of bits required by time domain resource indication is reduced, and signaling overhead is reduced.

Referring to fig. 1, fig. 1 is a flowchart illustrating a method for scheduling uplink time domain resources according to an embodiment of the present application, where the method may be executed on a network device providing a wireless function for a terminal device, and as shown in the figure, the method includes:

s101, determining uplink time domain resources allocated to the terminal equipment.

Specifically, the uplink time domain resource allocated to the terminal device may be determined according to the current service type of the terminal device, the current time domain scheduling mode configured for the terminal device, the current time domain resource required by the terminal device, the current allocation condition of the uplink time domain resource, and the like. For example, when a terminal device is performing a high-reliability Low-Latency (URLLC) service, a current service type of the terminal device is URLLC, and if time domain resources required by the terminal device are 3 Orthogonal Frequency Division Multiplexing (OFDM) symbols and currently idle uplink time domain resources are more, it is determined that uplink time domain resources allocated to the terminal device are uplink time domain resources of 3 OFDM symbols.

S102, determining a target time domain resource indication in an uplink time domain resource index table according to a time domain scheduling mode configured for the terminal device and the uplink time domain resource, where the target time domain resource indication is used to indicate a first starting symbol of the uplink time domain resource in a time slot and a first symbol number corresponding to the uplink time domain resource, the first starting symbol is a starting symbol in a starting symbol set associated with the time domain scheduling mode and a time slot acquisition mode, and the first symbol number is a symbol number in a symbol number set associated with the time domain scheduling mode, the time slot acquisition mode and the starting symbol.

In the embodiment of the present application, the time domain scheduling mode refers to a time domain scheduling mode currently configured for the terminal device, where the time domain scheduling mode configured for the terminal device is determined by a service type of the terminal device. For example, if the current service performed by the terminal device is an enhanced Mobile broadband (eMBB) service, the current time domain scheduling mode configured for the terminal device is a time domain scheduling mode based on a time slot; for another example, if the service currently performed by the terminal device is a URLLC service, the time domain scheduling mode currently configured for the terminal device is a time domain scheduling mode based on a micro slot, and is not limited to the description herein.

In the embodiment of the present application, the timeslot knowing mode refers to whether the terminal device knows the symbol distribution of the timeslot, where if the terminal device does not know the symbol distribution of the timeslot, the timeslot knowing mode is an unknown mode, and if the terminal device knows the symbol distribution of the timeslot, the timeslot knowing mode is a known mode.

Here, there are two possible cases where the slot-aware mode is an unknown mode: 1) the symbol distribution condition of the time slot is not informed to the terminal equipment at present; 2) the terminal device has been informed of the symbol distribution of the slot currently through RRC signaling or DCI signaling, but has not yet confirmed that the terminal device has received correctly. The slot learning mode is specifically a known mode: the terminal device has been informed of the symbol distribution of the slot by RRC signaling or DCI signaling, and has confirmed that the terminal device has correctly received.

Here, the symbol distribution of the slot refers to the number of Downlink (DL) symbols, flexible Uplink (UL) symbols, and flexible Downlink (unlown or flexible) symbols included in the slot, and the positions of the DL symbols, the unlown or flexible symbols, and the UL symbols in the slot, where the DL symbols are earlier in the slot than the unlown or flexible symbols in the slot, and the unlown or flexible symbols are earlier in the slot than the UL symbols in the slot. The symbol distribution of the slot may be as shown in fig. 2, where a is a case where a slot only includes DL symbols, B is a case where B slot only includes unknown or flexible symbols, C is a case where C slot only includes UL symbols, D is a case where D slot includes DL symbols and unknown or flexible symbols, E is a case where E slot includes DL symbols and UL symbols, F is a case where F slot includes unknown or flexible symbols and UL symbols, and G is a case where G slot includes DL symbols, unknown or flexible symbols and UL symbols.

In the embodiment of the application, under the condition that the time slot learning mode is an unknown mode, all symbols in the time slot can be used as unknown or flexible symbols, and the unknown or flexible symbols can be used for uplink transmission and downlink transmission; in the case where the slot-learning mode is a known mode, the symbol distribution of the slot may be any one of a to G in fig. 2.

In the embodiment of the present application, the number of the starting symbols in the starting symbol set associated with the time domain scheduling mode and the time slot learning mode and the number of the symbols in the symbol number set associated with the time domain scheduling mode, the time slot learning mode and the starting symbols may be as follows:

in the first case, the time domain scheduling mode configured for the terminal device is a time domain scheduling mode based on a time slot, and the time slot learning mode is an unknown mode. The position of the starting symbol in the starting symbol set in the slot is earlier than or equal to the position of the corresponding first symbol indicated by the PDSCH-start in the RRC signaling, and the target symbol number in the symbol number set is determined by the difference between the total number of symbols contained in the slot and the number of second symbols in the slot before the target starting symbol in the starting symbol set.

In this application, the second symbol refers to a symbol positioned before the start symbol in the slot.

Specifically, for example, the PDSCH-start indicates that the corresponding first symbol is the 3 rd symbol in the slot, the starting symbol in the starting symbol set may be the 1 st symbol, the 2 nd symbol or the 3 rd symbol in the slot, and the target symbol number in the symbol number set may be 14 (the target starting symbol is the 1 st symbol in the slot), 13 (the target starting symbol is the 2 nd symbol in the slot) or 12 (the target starting symbol is the 3 rd symbol in the slot).

In the second case, the time domain scheduling mode configured for the terminal device is the micro-slot-based time domain scheduling mode and the time slot learning mode is the unknown mode. A starting symbol in the starting symbol set is at any position in the slot, a target number of symbols in the symbol number set is greater than or equal to 1, and is less than or equal to a difference between a total number of symbols contained in the slot and a number of second symbols in the slot before the target starting symbol in the starting symbol set, and is less than or equal to 13.

Specifically, the starting symbol in the starting symbol set may be the 1 st symbol, the 2 nd symbol, …, the 14 th symbol, and the target symbol number in the symbol number set may be 1 to 13 (the target starting symbol is the 1 st symbol in the slot), 1 to 13 (the target starting symbol is the 2 nd symbol in the slot), …, 1 (the target starting symbol is the 14 th symbol in the slot).

In the third case, the time domain scheduling mode configured for the terminal device is a time domain scheduling mode based on the time slot, and the time slot learning mode is a known mode. The position of the starting symbol in the starting symbol set in the time slot is later than or equal to the position of the first flexible uplink and downlink symbol in the time slot, and is earlier than or equal to the position of the first uplink symbol in the time slot or the position of the last symbol in the time slot, and the target symbol number in the symbol number set is determined by the difference between the total number of symbols contained in the time slot and the number of second symbols in the time slot before the target starting symbol in the starting symbol set.

Specifically, for example, the first flexible uplink and downlink symbol in the slot is the 5 th symbol in the slot, and the first uplink symbol is the 9 th symbol in the slot, the target start symbol in the start symbol set may be the 5 th symbol, the 6 th symbol, the 7 th symbol, the 8 th symbol, the 9 th symbol in the start symbol set, and the target symbol number in the symbol number set may be 10 (the target start symbol is the 5 th symbol in the slot), 9 (the target start symbol is the 6 th symbol in the slot), …, 6 (the target start symbol is the 9 th symbol in the slot). For another example, the first flexible uplink and downlink symbol in the slot is the 5 th symbol in the slot, and there is no uplink symbol in the slot, the target start symbol in the start symbol set may be the 5 th symbol, the 6 th symbol, …, and the 14 th symbol in the slot, and the target symbol number in the symbol number set may be 10 (the target start symbol is the 5 th symbol in the slot), 9 (the target start symbol is the 6 th symbol in the slot), …, 1 (the target start symbol is the 14 th symbol in the slot).

In the fourth case, the time domain scheduling mode configured for the terminal device is a micro-slot-based time domain scheduling mode, and the slot learning mode is a known mode. The position of the starting symbol in the starting symbol set in the time slot is any one of the positions of the flexible uplink and downlink symbols and the position of the uplink symbol, the target symbol number in the symbol number set is greater than or equal to 1, and is less than or equal to the difference between the total number of symbols contained in the time slot and the number of second symbols before the target starting symbol in the starting symbol set in the time slot, and is less than or equal to 13.

Specifically, for example, the timeslot includes 3 flexible uplink and downlink symbols and 5 uplink symbols, the target start symbol in the start symbol set may be the 7 th symbol, the 8 th symbol, …, and the 14 th symbol in the timeslot, and the target symbol number in the symbol number set may be 1 to 8 (the target start symbol is the 7 th symbol in the timeslot), 1 to 7 (the target start symbol is the 8 th start symbol in the timeslot), …, 1 (the target start symbol is the 14 th symbol in the timeslot).

Here, the combinations of the starting symbol and the number of symbols formed by correspondingly combining the starting symbol in the starting symbol set and the number of symbols in the symbol number set in the four cases may be as shown in tables 3 to 6, where the following describes the combination of the starting symbol in the starting symbol set and the number of symbols in the symbol number set in combination with tables 3 to 6, where table 3 is the combination case in the first case, where the maximum value of PDSCH-start is 4, that is, the first symbol is at the latest the 4 th symbol in the slot:

initial symbol	Number of symbols
		1	14
2	13
		3	12
4	11

TABLE 3

As can be seen from table 3, in the first case, there are at most 4 combinations of the starting symbol and the number of symbols of the uplink time domain resource, if the 4 combinations in table 3 are indicated by using the time domain resource indication, the number of bits required by the time domain resource indication is at most 2, and since the first starting symbol and the first symbol number respectively belong to the starting symbol set and the symbol number set in the first case, the number of bits occupied by the target time domain resource indication is 2, which reduces signaling overhead.

Table 4 is the combination in the second case:

initial symbol	Number of symbols
		1	1，2，3，4，…，13
2	1，2，3，4，…，13
		3	1，2，3，4，…，12
…	…
		14	1

TABLE 4

As can be seen from table 4, in the second case, there are at most 1+2+3+ … +13+13=104 combinations of the starting symbol and the number of symbols of the uplink time domain resource, and if the time domain resource indication indicates 104 combinations in table 4, the time domain resource indication needs 7 bits at most, that is, the target time domain resource indicates 7 bits, which saves signaling overhead.

Table 5 is a combination case in the third case, where the first flexible uplink and downlink symbol is at the earliest the 1 st symbol in the slot, and the first uplink symbol is at the latest the last symbol in the slot:

initial symbol	Number of symbols
		1	14
2	13
		3	12
…	…
		14	1

TABLE 5

As can be seen from table 5, in the third case, there are at most 14 combinations of the starting symbol and the number of symbols of the uplink time domain resource, and if the 14 combinations in table 5 are indicated by using the time domain resource indication, the number of bits required by the time domain resource indication is at most 4, that is, the number of bits indicated by the target time domain resource is 4, which saves signaling overhead.

Table 6 shows the combination in the fourth case, where the flexible uplink and downlink signal or uplink symbol is the first symbol in the timeslot at the earliest and the flexible uplink and downlink symbol or uplink symbol is the second symbol in the timeslot at the latest:

TABLE 6

As can be seen from table 6, there are at most 104 combinations of starting symbols and symbol numbers, and if the combinations of 104 in table 6 are indicated by using the time domain resource indication, the number of bits required by the time domain resource indication is at most 7, that is, the number of bits indicated by the target time domain resource is 7, thereby saving signaling overhead.

It should be noted that tables 3 to 6 show the maximum value of the combination types, and in an alternative embodiment, some combinations may be selected from the combinations shown in tables 3 to 6 as combination parameters of the starting symbol and the number of symbols of the uplink time domain resource, so as to reduce the number of combinations, and further reduce the number of bits required for indicating the time domain resource indication of the uplink time domain resource, so as to save signaling overhead.

In a possible implementation manner, four uplink time domain resource index tables may be respectively designed to store the corresponding relationship between the combinations in tables 3 to 6 and the time domain resource indications, where the uplink time domain resource index tables are formed by correspondingly combining the start symbol set and the symbol number set corresponding thereto. The uplink time domain resource index table formed by the initial symbol set and the symbol number set correspondingly is described below.

Specifically, for the combination shown in table 3, an uplink time domain resource index table shown in table 7 may be designed:

time domain resource indication	Initial symbol	Number of symbols	Time domain scheduling mode	Time slot learn mode
					00	1	14	A	Is unknown
01	2	13	A	Is unknown
					10	3	12	A	Is unknown
11	4	11	A	Is unknown

Wherein, the time domain scheduling mode is a mode indicating that the time domain scheduling mode is a time domain scheduling mode based on a time slot, and in table 7, 4 combinations of the starting symbols in the starting symbol set and the number of symbols in the symbol number set are respectively indicated by 00 to 11 when the time domain scheduling mode configured for the terminal device is the time domain scheduling mode based on the time slot and the time slot learning mode is an unknown mode.

For the combination shown in table 4, an uplink time domain resource index table as shown in table 8 can be designed:

					0011001	2	13	B	Is unknown
…	…	…	B	Is unknown
					1100111	14	1	B	Is unknown

TABLE 8

Wherein, the time domain scheduling mode is B, which means that the time domain scheduling mode is a micro-slot-based time domain scheduling mode, and in table 8, 104 combinations of the starting symbols in the starting symbol set and the number of symbols in the symbol number set are respectively indicated by using time domain resource indications with a value range of 0000000-1100111 when the time domain scheduling mode configured for the terminal device is the micro-slot-based time domain scheduling mode and the time slot learning mode is an unknown mode.

For the combination shown in table 5, an uplink time domain resource index table as shown in table 9 can be designed:
