Fig. 1 shows a block diagram of a wireless communication system to which embodiments of the present application are applicable. The wireless communication system includes a terminal 11 and a network-side device 12. Wherein, the terminal 11 may also be called a terminal Device or a User Equipment (UE), the terminal 11 may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer) or a notebook Computer, a Personal Digital Assistant (PDA), a palmtop Computer, a netbook, a super-Mobile Personal Computer (UMPC), a Mobile Internet Device (MID), a Wearable Device (Wearable Device) or a vehicle-mounted Device (VUE), a pedestrian terminal (PUE), and other terminal side devices, the Wearable Device includes: smart watches, bracelets, earphones, glasses, and the like. It should be noted that the embodiment of the present application does not limit the specific type of the terminal 11. The network-side device 12 may be a Base Station or a core network, where the Base Station may be referred to as a node B, an evolved node B, an access Point, a Base Transceiver Station (BTS), a radio Base Station, a radio Transceiver, a Basic Service Set (BSS), an Extended Service Set (ESS), a node B, an evolved node B (eNB), a home node B, a WLAN access Point, a WiFi node, a Transmit Receiving Point (TRP), or some other suitable terminology in the field, as long as the same technical effect is achieved, the Base Station is not limited to a specific technical vocabulary, and it should be noted that, in the embodiment of the present application, only the Base Station in the NR system is taken as an example, but a specific type of the Base Station is not limited.

Currently, in a TDD communication system, when a network side device configures a slot format, the network side device may be configured by using TDD-UL-DL-ConfigCommon. Specifically, the network side device may indicate the number of time slots for downlink transmission through the indication field nrofDownlinkSlots, indicate the number of time slots for uplink transmission using the indication field nrofUplinkSlots, and the remaining time slots may be flexible time slots (in the case where the uplink/downlink transmission period and the SCS are determined, the number of time slots in each frame is fixed, and after the network side device indicates the number of time slots for uplink transmission and downlink transmission, the remaining time slots are the number of flexible time slots). Wherein, the nrofDownlinkSlots and the nrofUplinkSlots each include a specific number of bits.

In the case that the frequency of the SCS is high, the number of slots that need to be configured may increase sharply, and thus, when the network-side device uses nrofdownlinlinskslots and nrofuplingslots to indicate the number of slots for downlink transmission and the number of slots for uplink transmission, respectively, the number of bits in the nrofdownlinlinslots and nrofuplingslots is limited, and a problem that a format of a part of the slots cannot be configured may occur.

Taking the SCS frequencies of 480KHz and 960KHz and the transmission cycle of 10ms as an example, when the frequency of the SCS is 480KHz and the transmission cycle of 10ms, the number of slots in one frame is 320, since the maximum number of uplink slots may be 320 (at this time, the number of downlink slots is 0), and the maximum number of downlink slots may also be 320 (at this time, the number of uplink slots is 0), therefore, the two indication fields nrofDownlinkSlots and nrofUplinkSlots may each include 9 bits, and thus, the format of each slot may be configured effectively. However, when the transmission cycle of the SCS with a frequency of 960KHz is 10ms, the number of slots in one frame will increase to 640, in this case, if 9 bits of nrofDownlinkSlots and nrofUplinkSlots are used to refer to the number of slots for downlink transmission and the number of slots for uplink transmission, respectively, the number of slots for uplink transmission/downlink transmission can be indicated by 512 at most, and when the number of slots for uplink transmission/downlink transmission is greater than 512, the number of slots for uplink transmission/downlink transmission will not be effectively indicated by nrofDownlinkSlots and nrofUplinkSlots.

In view of the fact that the number of different uplink and downlink transmission time slots under more scenes can be indicated by means of indexes, a unique corresponding first index can be determined in advance for the number of uplink and downlink transmission time slots under different scenes, when the network side equipment configures the format of the time slots, the first index can be indicated by a first indication field in configuration information, and the number of uplink transmission time slots and the number of downlink transmission time slots are determined by the terminal based on the first index. In this way, because the format of a larger number of slots can be indicated by means of the index, when the number of slots needing to be configured is larger, the number of slots in different formats can be effectively indicated by the first index, so that the format of each slot can be effectively configured.

The timeslot configuration method, the terminal and the network side device provided by the embodiments of the present application are described in detail below with reference to the drawings and some embodiments and application scenarios thereof.

As shown in fig. 2, the present embodiment provides a timeslot configuration method 200, which may be performed by a terminal, in other words, by software or hardware installed in the terminal, and the method includes the following steps.

S202: the terminal receives configuration information, wherein the configuration information comprises a first indication field, and the first indication field is used for indicating a first index.

In S202, the network side device may determine, in advance, a corresponding first index for the number of uplink and downlink time slots in different scenarios, where the first index may correspond to unique uplink time slot data and unique downlink time slot number. In this way, when configuring the slot format, the network side device may send configuration information to the terminal device, where the configuration information includes a first indication field, and the first indication field is used to indicate the first index.

The first indication field may be composed of one indication field or a plurality of indication fields. Alternatively, the plurality of indication fields may be two indication fields nroflinkslots and nroflinlinkslots in a TDD-UL-DL-configuration common configuration in the related art. The first indication field may include a plurality of bits therein, and the plurality of bits may be used to indicate the first index. Alternatively, the maximum value of the plurality of bits may be greater than the maximum value of the first index, which may be understood as the combined number of the number of slots for different uplink and downlink transmissions.

After the network side device sends the configuration information to the terminal, the terminal may receive the configuration information from the network side device.

S204: a first number of timeslots for uplink transmission and a second number of timeslots for downlink transmission are determined based on the first index.

After receiving the configuration information, the terminal may determine the number of uplink slots and the number of downlink slots based on the first index indicated by the configuration information. Here, for the sake of distinction, the number of slots for uplink transmission may be represented by a first number of slots, and the number of slots for downlink transmission may be represented by a second number of slots.

In this embodiment, when determining the first number of time slots and the second number of time slots based on the first index, the terminal may be implemented in at least two ways, and the two ways will be described below.

The first implementation mode comprises the following steps:

the terminal may determine a first number of time slots based on the first index and a predefined first function and a second number of time slots based on the first index and a predefined second function.

The first function may be related to the first number of slots, the total number of slots, and the first index, i.e., the first function may represent a functional relationship between the first number of slots, the total number of slots, and the first index. The second function may be related to the second number of slots and the first index, i.e. the second function may characterize a functional relationship between the second number of slots and the first index. The total number of time slots can be determined based on the current SCS and the transmission period of the uplink and downlink.

Alternatively, the first function may be related to the first number of slots and the first index, and the first function may characterize a functional relationship between the first number of slots and the first index. The second function is related to the second number of slots, the total number of slots, and the first index, and may characterize a functional relationship between the second number of slots, the total number of slots, and the first index.

The first function and the second function may be predefined by a protocol, and a unique first number of time slots may be determined based on the first function and the first index, and a unique second number of time slots may be determined based on the second function and the first index.

For ease of understanding, how the network side device determines (or the protocol predefines) the first function and the second function and how the terminal determines the first slot number and the second slot number based on the first function and the second function may be described below by taking 640 slot numbers (which may correspond to an SCS of 960KHz and a transmission cycle of 10 ms) that need to be configured and 18 bits (which may be bits in nrofDownlinkSlots and nrofUplinkSlots) included in the first indication field as examples.

In the case that there are 640 total slots in the dl-UL-transmission periodicity period, the correspondence between the first index x indicated by 18 bits and the number of slots for different uplink and downlink transmissions may be obtained in consideration of the number of slots for all possible uplink and downlink transmissions, as shown in table 1 below.

TABLE 1

First index x	First number of slots Y1	A second number of time slots Y2
			000…00	M	0
000…01	M-1	0
			000…10	M-1	1
	M-2	0
				M-2	1
	M-2	2
				……
	0	M-1
			111…11	0	M

M in table 1 above is 639. As can be seen from table 1, the total number of time slots for all possible uplink and downlink transmissions is 1+2+ \8230; +640= 205120. Consider that the maximum index for 18 bits is 2 ¹⁸ -1=262143, greater than 205120, so the first index indicated by 18 bits can be used to represent 205120 combinations, and each combination can correspond to oneA first index, one first index may correspond to a unique first number of slots Y1 and a unique second number of slots Y2. The first slot number Y1 may be expressed by a function having a first index x, and the second slot number Y2 may be derived by the first slot number Y1 and the first index x.

The derivation of the first and second functions may be as follows:

assuming that the same first slot number Y1 in table 1 corresponds to a group i, the relationship between x and i can be expressed as follows:

the formula for i can be derived based on the above formula:

since i is an integer, the following relationship equation between i and the first index x can be determined based on the above formula of i:

since the same first slot number may correspond to a group i, the first slot number Y1 may be expressed as the following formula:

m is a value obtained by subtracting one from the total number of slots, and M is 639 when the total number of slots is 640.

For the second number of slots Y2, the relationship of Y2 to the first index x may be expressed as the following equation:

the following lighting relationship between Y2 and the first index x can be obtained by deriving the formula of Y2:

based on the derivation process described above, it can be determined that the first function is:

the second function is:

based on the same derivation, the first function can also be determined as:

the second function is:

based on the first function and the second function, when determining the first number of time slots and the second number of time slots based on the first index, the terminal may determine a unique first number of time slots based on the first function and a unique second number of time slots based on the second function.

It should be noted that, the formula derivation process of the first function and the second function is described by taking the total number of slots as an example, and in the case that the total number of slots is other numbers, the first function and the second function may also be derived based on the same method, and here, the derivation processes of the first function and the second function in other total numbers of slots are not illustrated.

The second implementation mode comprises the following steps:

the terminal may determine the second index based on the first index and a predefined first formula. If the second index is less than the first specified value, the first number of time slots may be determined based on the first index and a predefined third function, and the second number of time slots may be determined based on the first index and a predefined fourth function. If the second index is greater than or equal to the first specified value, the first number of slots may be determined based on the first index and a predefined fifth function, and the second number of slots may be determined based on the first index and a predefined sixth function.

The first specified value may be determined based on the total number of timeslots, which may be pre-configured by the network side device or predefined by the protocol, and the total number of timeslots is determined by the SCS and the transmission period of the uplink and downlink. Alternatively, the first specified value may be equal to the total number of time slots minus one.

The first formula is related to the first index and a second specified value, which may also be determined based on the total number of timeslots, specifically pre-configured by the network side device or predefined by the protocol. The first specified value and the second specified value may be the same or different.

The third function, the fourth function, the fifth function, and the sixth function described above are all related to the first index and the second specified value, but the four functions are different from the functional relationship between the first index and the second specified value. Specifically, the third function represents a first functional relationship between the first number of slots and the first index and the second specified value, the fourth function represents a second functional relationship between the second number of slots and the first index and the second specified value, the fifth function represents a third functional relationship between the first number of slots and the first index and the second specified value, and the sixth function represents a fourth functional relationship between the second number of slots and the first index and the second specified value.

The third function, the fourth function, the fifth function, and the sixth function may be predefined by a protocol, and a unique first number of slots may be determined based on the third function, the first index, and the second specified value, a unique second number of slots may be determined based on the fourth function, the first index, and the second specified value, a unique first number of slots may be determined based on the fifth function, the first index, and the second specified value, and a unique second number of slots may be determined based on the sixth function, the first index, and the second specified value.

In a possible implementation manner, the first index may be determined by referring to a calculation manner of similar index values (starting position and length flag values, abbreviated as SLIV), so as to obtain the third function, the fourth function, the fifth function, and the sixth function. The specific implementation is as follows.

First, a boundary value a may be set for the first slot number and the second slot number, a being a positive integer. Alternatively, a may be determined by the total number of slots, and may specifically be represented as:

or

B is an integer, the value may be-1, 0, or 1, and the like, specifically configured in advance by the network side device or predefined by the protocol, and M is determined by the total number of time slots, optionally, M may be equal to the total number of time slots minus one.

Secondly, referring to the calculation method of the SLIV, the first index x may be obtained as follows:

if 0＝<Y1<＝A

x＝M*(Y1+Q)+Y2+N

Else A<Y1<＝M

x＝M*(M–Y1+G)+M–Y2+H。

alternatively, it may be:

if 0＝<Y2<＝A

x＝M*(Y2+Q)+Y1+N

Else A<Y2<＝M

x＝M*(M–Y2+G)+M–Y1+H。

q, N, G, and H are integers, and at least one of Q, N, G, and H may be configured by a network side device or predefined by a protocol. Alternatively, Q, N, G, H and the above M, a may satisfy the following relation:

N+Q<0，G+H>＝0，A>＝(M+1-MQ-N)/(M-1)。

in the case that the total number of timeslots is M, the number of combinations of the number of timeslots for different uplink and downlink transmissions may be expressed as follows:

when the network side device configures the first index, the maximum numerical value corresponding to the plurality of bits used needs to be greater than the number of combinations.

The terminal may determine the second index based on a predefined first formula after receiving the first index. Alternatively, the first formula may be expressed as

Wherein M may be regarded as the second specified value, specifically, the total number of timeslots is decreased by one.

After determining the second index, if the second index is smaller than the first specified value, it may be determined that the relationship between the first slot number and the size of the boundary value a is 0= and<Y1<= A, in this case can be obtained

Y2= x% M-N. If the second index is greater than or equal to the first designated value, it is determined that the first slot number and the boundary value A have a size relationship of A<Y1<= M, in this case, can be obtained

Y2＝M+H-x％M。

Alternatively, after the second index is determined, if the second index is smaller than the first specified value, it may be determined that the size relationship between the second slot number and the boundary value a is 0= and<Y2<= a, in which case Y1= x% M-N can be obtained,

if the second index is greater than or equal to the first designated value, it is determined that the first slot number and the boundary value A have a size relationship of A<Y1<= M, in which case Y1= M + H-x% M can be obtained,

through the above steps, the terminal may determine a unique first slot number and a unique second slot number based on the first index. Wherein the third function is:

the fourth function is: y2= x% M-N, or, the third function is: y1= x% M-N, the fourth function being:

the fifth function is:

the sixth function is: y2= M + H-x% M, or, the fifth function is: y1= M + H-x% M, the sixth function being:

in the embodiment of the application, a unique corresponding first index may be determined in advance for the number of uplink and downlink transmission slots in different scenarios, when the network side device configures the format of the slot, the first index may be indicated by a first indication field in the configuration information, and the terminal determines the number of uplink transmission slots and the number of downlink transmission slots based on the first index. In this way, because the format of a greater number of slots can be indicated by means of the index, when the number of slots that need to be configured is greater, the number of slots of different formats can be effectively indicated by the first index, so that the format of each slot can be effectively configured.

As shown in fig. 3, the present embodiment provides a timeslot configuration method 300, which may be performed by a network-side device, in other words, the method may be performed by software or hardware installed in the network-side device, and the method includes the following steps.

S302: the network side equipment sends configuration information, wherein the configuration information comprises a first indication field, the first indication field is used for indicating a first index, and the first index is used for determining the first time slot number of uplink transmission and the second time slot number of downlink transmission.

In S302, the network side device may determine, in advance, a corresponding first index for the number of uplink and downlink time slots in different scenarios, where the first index may correspond to unique uplink time slot data and unique downlink time slot number. Thus, when configuring the slot format, the network side device may send configuration information to the terminal device, where the configuration information includes a first indication field, and the first indication field is used to indicate the first index.

In an implementation manner, the first index is used for determining the first number of time slots and the second number of time slots, and specifically, the first index and a predefined first function are used for determining the first number of time slots, and the first index and a predefined second function are used for determining the second number of time slots. The first function, the first slot number, the total slot number and the first index may represent a functional relationship between the first slot number, the total slot number and the first index. The second function is related to the second time slot number and the first index, and can characterize the functional relationship between the second time slot number and the first index, and the total number of the time slots is determined by the transmission period of the SCS. Alternatively, the first function is related to the first number of slots and the first index, and the first function may characterize a functional relationship between the first number of slots and the first index. The second function is related to the second number of slots, the total number of slots, and the first index, and may characterize a functional relationship between the second number of slots, the total number of slots, and the first index.

The first function and the second function may be pre-configured by the network side device or predefined by a protocol. In a possible implementation manner, the specific derivation processes of the first function and the second function can be referred to the corresponding contents in the embodiment shown in fig. 2, and the description is not repeated here.

In another implementation, the first index is further used to determine the second index by a predefined first formula. In this case, the first index is used to determine the first number of slots and the second number of slots, and specifically, in a case where the second index is smaller than the first specified value, the first index and a predefined third function are used to determine the first number of slots, and the first index and a predefined fourth function are used to determine the second number of slots. In the case where the second index is greater than or equal to the first specified value, the first index and the predefined fifth function are used to determine the first number of slots, and the first index and the predefined sixth function are used to determine the second number of slots. The first designated value may be determined based on the total number of timeslots, specifically pre-configured by the network side device or predefined by the protocol, and the total number of timeslots may be determined by the current SCS and transmission period.

The first formula is associated with a first index and a second specified value, the second specified value being determined based on the total number of time slots. Third function the fourth function, the fifth function and the sixth function are each related to the first index and the second specified value, wherein the third function characterizes a first functional relationship between the first number of slots and the first index and the second specified value. The fourth function characterizes a second functional relationship between the second number of slots and the first index and the second specified value. The fifth function characterizes a third functional relationship between the first number of slots and the first index and the second specified value. The sixth function characterizes a fourth functional relationship between the second number of slots and the first index and the second specified value.

In a possible implementation manner, the third function, the fourth function, the fifth function and the sixth function may be determined by referring to a calculation manner of similar index values (starting position and length flag values, abbreviated as SLIV), and may specifically refer to corresponding contents in the embodiment shown in fig. 2, and a description thereof is not repeated here.

In this embodiment, after the network side device sends the configuration information to the terminal, the terminal may determine the corresponding first slot number and second slot number based on the first index indicated in the configuration information, and a specific implementation manner may refer to the embodiment shown in fig. 2, which is not described again here.
