Description

Technical Field

[0001] This application belongs to the field of terminal communication technology, specifically relating to a time slot configuration method, a terminal, and a network-side device. Background Technology

[0002] In communication systems, terminals and network-side devices can use different subcarrier spacings (SCS) for data and control channel transmission. Typically, a frame can include multiple time slots for different subcarrier spacings. To support more flexible scheduling, especially in Time Division Duplex (TDD) systems, different time slot formats can be designed for each frame, and the network-side device configures the format of the time slots within each frame during communication. Specifically, the time slot format can include three types: a time slot used only for downlink transmission, or only for uplink transmission, or a hybrid time slot. When configuring the time slot format, the network-side device can configure the number of time slots used for uplink transmission and the number of time slots used for downlink transmission; the remaining unconfigured time slots can be flexible time slots.

[0003] Currently, higher frequency SCSs have been introduced into communication systems. With higher SCS frequencies, the number of time slots that need to be configured increases dramatically. As a result, when network-side devices configure the format of time slots within each frame based on the current scheme, they may encounter problems in effectively configuring the format of certain time slots. Summary of the Invention

All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0037] It is worth noting that the technologies described in this application are not limited to Long Term Evolution (LTE) / LTE-Advanced (LTE-A) systems, but can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA), and other systems.

The following description describes New Radio (NR) systems for illustrative purposes, and the term NR is used in most of the following description; however, these technologies can also be applied to applications other than NR systems, such as 6th generation (6G) radio systems. th Generation 6G communication system.

[0038] Figure 1This diagram illustrates a block diagram of a wireless communication system applicable to embodiments of this application. The wireless communication system includes a terminal 11 and a network-side device 12. The terminal 11 can also be referred to as a terminal device or user equipment (UE). The terminal 11 can be a mobile phone, tablet computer, laptop computer, personal digital assistant (PDA), handheld computer, netbook, ultra-mobile personal computer (UMPC), mobile internet device (MID), wearable device, vehicle-mounted device (VUE), pedestrian terminal (PUE), etc. Wearable devices include smartwatches, wristbands, headphones, glasses, etc. It should be noted that this application does not limit the specific type of terminal 11.

The base station is not limited to specific technical terms. It should be noted that in this application embodiment, only the base station in the NR system is used as an example, but the specific type of base station is not limited.

[0039] Currently, in TDD communication systems, network-side devices can use TDD-UL-DL-ConfigCommon to configure the timeslot format. Specifically, the network-side device can indicate the number of timeslots for downlink transmission using the `nrofDownlinkSlots` field and the number of timeslots for uplink transmission using the `nrofUplinkSlots` field. The remaining timeslots can be flexible (given that the uplink / downlink transmission period and SCS are fixed, the number of timeslots per frame is fixed; after the network-side device indicates the number of timeslots for uplink and downlink transmission, the remaining number of timeslots is the number of flexible timeslots). Both `nrofDownlinkSlots` and `nrofUplinkSlots` include a specific number of bits.

[0040] When the frequency of SCS is high, the number of time slots in a frame will increase dramatically. As a result, when network-side devices use nrofDownlinkSlots and nrofUplinkSlots to indicate the number of time slots for downlink transmission and uplink transmission respectively, they will encounter the problem of being unable to configure the format of some time slots due to the limited number of bits in nrofDownlinkSlots and nrofUplinkSlots.

[0041] Taking SCS frequencies of 480kHz and 960kHz and a transmission period of 10ms as an example, when the SCS frequency is 480kHz and the transmission period is 10ms, the number of time slots in one frame is 320. Since the maximum number of uplink transmission time slots can be 320 (at which time the number of downlink transmission time slots is 0), and the maximum number of downlink transmission time slots can also be 320 (at which time the number of uplink transmission time slots is 0), the two indicator fields nrofDownlinkSlots and nrofUplinkSlots can each contain 9 bits, thereby enabling effective configuration of the format of each time slot. However, when the SCS frequency is 960kHz and the transmission period is 10ms, the number of time slots in one frame will increase to 640. In this case, if 9 bits of nrofDownlinkSlots and nrofUplinkSlots are used to indicate the number of downlink and uplink time slots respectively, a maximum of 512 uplink / downlink time slots can be indicated. When the number of uplink / downlink time slots is greater than 512, it will be impossible to effectively indicate the number of uplink / downlink time slots through nrofDownlinkSlots and nrofUplinkSlots.

[0042] To address the current problem of the inability to effectively configure the format of certain time slots, embodiments of this application provide a time slot configuration method, a terminal, and a network-side device. When the number of time slots is large, by dividing the existing number of bits into multiple groups of bits and using multiple groups of bits to jointly indicate the number of time slots in different formats, or by adding new bits and combining them with the existing number of bits to jointly indicate the number of time slots in different formats, the number of time slots in different formats can be effectively indicated, thereby enabling effective configuration of the format of each time slot.

[0043] It should be noted that the embodiments of this application can solve the above-mentioned technical problems in two different ways. One way is that, considering the sum of the number of uplink transmission slots and the number of downlink transmission slots does not exceed the total number of slots, it is not necessary to allocate more bits to indicate the number of uplink transmission slots and the number of downlink transmission slots respectively. For example, in the case of the above-mentioned SCS of 960KHz and transmission period of 10ms, it is not necessary to allocate 10 bits to nrofDownlinkSlots and nrofUplinkSlots respectively. Another way is to increase the number of bits, thereby using more bits to configure the format of more slots. For example, in the case of the above-mentioned SCS of 960KHz and transmission period of 10ms, 10 bits can be used to indicate the number of uplink transmission slots and the number of downlink transmission slots respectively.

[0044] The time slot configuration method, terminal, and network-side device provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0045] like Figure 2 As shown in the figure, this application embodiment provides a time slot configuration method 200, which can be executed by a terminal. In other words, the method can be executed by software or hardware installed on the terminal. The method includes the following steps.

[0046] S202: The terminal receives configuration information, which includes a first indication field. The configuration information is used to indicate a first target bit and a second target bit through a first indication method or a second indication method. The first target bit is used to indicate the number of uplink transmission time slots, and the second target bit is used to indicate the number of downlink transmission time slots. The first indication method includes dividing multiple bits in the first indication field into multiple groups of bits and using multiple groups of bits for joint indication. The second indication method includes using the first indication field in conjunction with other fields for joint indication.

[0047] When configuring the timeslot format, the network-side device can send configuration information to the terminal. This configuration information is used to indicate the number of bits (i.e., the first target bits) used to indicate the number of timeslots for uplink transmission and the number of bits (i.e., the second target bits) used to indicate the number of timeslots for downlink transmission, either through a first indication method or a second indication method.

[0048] The configuration information described above may include a first indication field, which may consist of one indication field or multiple indication fields. Optionally, these multiple indication fields may be the two indication fields nrofDownlinkSlots and nrofUplinkSlots in the current TDD-UL-DL-ConfigurationCommon configuration. The first indication field may include multiple bits, the number of which may be the total number of bits used to indicate the number of uplink transmission slots and the number of bits used to indicate the number of downlink transmission slots in the prior art. Of course, the number of these multiple bits may also be configured by the network-side device according to the actual situation, and no specific limitation is made here.

[0049] The first indication method described above can be understood as changing the way bits are indicated, i.e., changing how the terminal interprets bits, without increasing the number of bits, to achieve the purpose of using existing multiple bits to indicate the format of more time slots. Specifically, it involves grouping existing multiple bits and using the grouped multiple bits for joint indication. The second indication method described above can be understood as adding multiple bits to the existing multiple bits to jointly indicate the number of uplink and downlink transmission time slots. Taking the need to indicate 640 time slots (corresponding to an SCS of 960kHz and a transmission period of 10ms) as an example, the existing multiple bits could be 18 bits (including 9 bits for indicating the number of uplink transmission time slots and 9 bits for indicating the number of downlink transmission time slots) used to indicate the format of 320 time slots (corresponding to an SCS of 480kHz and a transmission period of 10ms) . Of course, in other SCS scenarios, the existing multiple bits can also be other numbers of bits, which will not be illustrated here.

[0050] In this embodiment, when the configuration information is used to indicate the first target bit and the second target bit through the first indication method, the multiple bits in the first indication field may include the first target bit and the second target bit. The first target bit and the second target bit do not overlap, and the sum of the number of the first target bit and the second target bit is less than or equal to the total number of bits in the first indication field. That is, the network-side device can use one or more bits from the first indication field as the first target bit and one or more bits from the remaining bits as the second target bit.

[0051] When the configuration information is used to indicate the first target bit and the second target bit through the aforementioned second indication method, the configuration information may further include a second indication field. This second indication field can be understood as other fields that, together with the first indication field, indicate the number of the first bit and the number of the second bit; that is, the second indication method represents indication jointly provided by the first indication field and the second indication field. Optionally, the second indication field and the first indication field may belong to the same indication domain, meaning the second indication field is a newly added field within the indication domain of the first indication field. Alternatively, the second indication field may belong to a different indication domain than the first indication field. The indication domain to which the second indication field belongs may be a newly added indication domain, or the second indication field may be an available field within a specified indication domain. This specified indication domain may be configured by the network-side device or predefined by the protocol. Optionally, this specified indication domain may be nrofUplinkSymbols or nrofDownlinkSymbols in the existing TDD-UL-DL-ConfigurationCommon configuration.

[0052] S204: Determine the first target bit and the second target bit based on the configuration information.

[0053] After receiving configuration information from the network-side device, the terminal can determine the first target bit and the second target bit based on the configuration information.

[0054] In this embodiment, when the terminal determines the first target bit and the second target bit based on the configuration information, it can determine the first target bit and the second target bit based on the first indication method or the second indication method. The specific indication method used can be configured by the network-side device, predefined by the protocol, or determined based on the actual situation. In one possible implementation, when the terminal determines based on the actual situation, it can determine whether a first preset condition is met. If so, the first target bit and the second target bit can be determined based on the second indication method; otherwise, the first target bit and the second target bit can be determined based on the first indication method.

[0055] The first preset condition mentioned above may include at least one of the following: the transmission frequency range of the System Information Block 1 (SIB1) is a specified frequency (e.g., FR2 / FR2-2), the SCS is a specified frequency (e.g., 960KHz), and the transmission period of the uplink / downlink is a specified period (e.g., 10ms).

[0056] Optionally, in certain specific scenarios, if the network-side device does not configure certain parameters, the terminal may not execute S204, that is, it may not determine the first target bit and the second target bit based on the time slot configuration method of this application embodiment. For example, when the SCS configured by the network-side device is 960KHz, the transmission period is not configured to be 10ms. In this way, the network-side device does not need to indicate the format of more time slots through existing bits, nor does it need to add new bits to jointly indicate the time slot format with existing bits. This application embodiment only uses the execution of S204 as an example for illustration.

[0057] The following will explain in detail how the terminal determines the first target bit and the second target bit based on the first indication method and the second indication method, respectively.

[0058] When the terminal determines the first target bit and the second target bit based on the first indication method, the specific implementation method is as follows:

[0059] S2041: Determine a first non-overlapping first bit, a second bit, and a third bit from a plurality of bits in a first indicator field based on a first method.

[0060] The sum of the number of the first, second, and third bits can be equal to the total number of bits in the first indicator field. This first method can be pre-configured by the network-side device or pre-defined by the protocol. That is, the network-side device or protocol can configure or define how many bits in the first indicator field are the first bit, how many are the second bit, and how many are the third bit. The number of the first, second, and third bits can be zero, one, or more; the specific number can be determined based on the actual situation and is not specifically limited here. For example, the network-side device can configure (or the protocol pre-define) that N bits out of P bits in the first indicator field are the first bit, M bits are the second bit, and Q bits are the third bit, where N, M, and Q are all integers greater than or equal to 0, and the sum of N, M, and Q is less than or equal to P.

[0061] Furthermore, the positions of the first, second, and third bits within the multiple bits of the first indication field can also be configured by the network-side device or predefined by the protocol. That is, the network-side device or protocol can configure or define which specific bit in the multiple bits of the first indication field is the first bit, which is the second bit, and which is the third bit. For example, the network-side device can configure (or the protocol predefine) that the first N bits of the P bits in the aforementioned first indication field are the first bit, the middle M bits are the second bit, and the last Q bits are the third bit; alternatively, it can configure the first N bits as the first bit, the last M bits as the second bit, and the middle Q bits as the third bit. Of course, other cases are also possible, which will not be illustrated here.

[0062] Optionally, network-side devices and protocols can pre-configure or pre-define the positions of the first bit, the second bit, and the third bit within the multiple bits of the first indication field using the first method described above. In other words, based on the first method, the terminal can determine not only the number of each of the first, second, and third bits, but also their specific positions within the multiple bits of the first indication field.

[0063] S2042: Determine the non-overlapping fourth and fifth bits from the third bit based on the second method.

[0064] When there are one or more third bits, the terminal can determine the non-overlapping fourth and fifth bits from the third bits based on the second method. The sum of the number of fourth and fifth bits can be less than or equal to the total number of third bits.

[0065] The second method involves pre-configuration by the network-side device or pre-definition by the protocol. Specifically, the network-side device or protocol configures or defines how many bits in the third bit can be the fourth bit and how many bits can be the fifth bit. The number of fourth and fifth bits can be zero, one, or more. Furthermore, the positions of the fourth and fifth bits within the third bit can also be configured by the network-side device or pre-defined by the protocol. That is, the network-side device or protocol can configure or define which specific bit in the third bit is the fourth bit and which is the fifth bit. Optionally, the network-side device and protocol can pre-configure or pre-define the positions of the fourth and fifth bits within the third bit using the second method described above. In other words, based on the second method, the terminal can determine not only the number of fourth and fifth bits but also their specific positions within the third bit.

[0066] When the terminal determines the non-overlapping fourth and fifth bits from the third bits based on the second method, it can specifically determine the sixth bit from the third bits based on the second method. Determining the sixth bit can involve identifying which specific bit in the third bits is the sixth bit. After determining the sixth bit, the fourth and fifth bits can be determined based on it. The sixth bit can be one or more bits from the third bits, and it is used to indicate the fourth and fifth bits. Specifically, it can indicate the number of each of the fourth and fifth bits, as well as their specific positions within the third bits.

[0067] In one implementation, when the terminal determines the fourth and fifth bits based on the sixth bit, it can determine the fourth and fifth bits jointly based on a first mapping relationship and the sixth bit. The first mapping relationship can be understood as the mapping relationship between the value of the sixth bit and the number of fourth bits and the number of fifth bits. This first mapping relationship can be pre-configured by the network-side device or predefined by the protocol. The fourth and fifth bits jointly indicated by the first preset mapping relationship and the sixth bit are the other bits in the third bit set, excluding the sixth bit.

[0068] Taking the third bit as an example of 6 bits, and assuming that the sixth bit is the first two bits, the first mapping relationship (that is, the mapping relationship between the value of the sixth bit and the number of the fourth bit and the number of the fifth bit) can be represented by Table 1 below.

[0069] Table 1

[0070] The value of the sixth bit Number of fourth bits Number of fifth bits 00 0 4 01 1 3 10 2 2 11 3 1

[0071] As shown in Table 1, when the sixth bit is 00, all remaining bits of the third bit can be used as the fifth bit, and the number of fourth bits is 0. When the sixth bit is 01, the first or last bit of the remaining bits of the third bit can be used as the fourth bit, and the remaining three bits can be used as the fifth bit. When the sixth bit is 10, the first two or last two bits of the remaining bits of the third bit can be used as the fourth bit, and the remaining two bits can be used as the fifth bit. When the sixth bit is 11, the first three or last three bits of the remaining bits of the third bit can be used as the fourth bit, and the remaining bit can be used as the fifth bit.

[0072] Of course, in other implementations, when the sixth bit has a value of 00 / 01 / 10 / 11, the number of fourth and fifth bits in Table 1 above can also be other numbers. For example, when the sixth bit has a value of 00, the remaining four bits of the third bit can all be used as the fourth bit, or the first or last bit of the remaining bits of the third bit can be used as the fourth bit, and one of the remaining three bits can be used as the fifth bit, and so on. These will not be illustrated in detail here.

[0073] In another implementation, when the terminal determines the fourth and fifth bits based on the sixth bit, it can combine one or more bits from the sixth bit to jointly determine the fourth and fifth bits, that is, one or more bits from the sixth bit can be used as the fourth or fifth bit, or as a part of the fourth or fifth bit.

[0074] Specifically, the non-overlapping eighth and ninth bits can be determined from the seventh bits based on the sixth bit and the second mapping relationship. The seventh bit refers to all bits in the third bits except the sixth bit, and there can be one or more seventh bits. Determining the eighth and ninth bits from the seventh bits can mean identifying which specific bit in the seventh bits is the eighth bit and which is the ninth bit. The sum of the number of eighth and ninth bits can be less than or equal to the total number of seventh bits. The second mapping relationship is the mapping relationship between the value of the sixth bit and the number of eighth and ninth bits. Optionally, when the number of sixth bits is fixed, this second mapping relationship can be the same as the first mapping relationship described above (the number of eighth bits equals the number of fourth bits, and the number of ninth bits equals the number of fifth bits, or the number of eighth bits equals the number of fifth bits, and the number of ninth bits equals the number of fourth bits).

[0075] After determining the eighth and ninth bits based on the second mapping relationship and the sixth bit, the fourth and fifth bits can be determined in any of the following ways:

[0076] The first method involves designating a specific bit from the eighth and sixth bits as the fourth bit, and the ninth bit as the fifth bit; alternatively, the eighth bit can be designated as the fourth bit, and a specific bit from the ninth and sixth bits can be designated as the fifth bit. The specific bit in the sixth bit can be one or more bits from the sixth bit set, which can be pre-configured by the network-side device or predefined by the protocol.

[0077] The second method: When the specified bit is set to the first specified value, the eighth bit and the specified bit are designated as the fourth bit, and the ninth bit is designated as the fifth bit; or, the eighth bit is designated as the fourth bit, and the ninth bit and the specified bit are designated as the fifth bit. The first specified value can be 0 or 1.

[0078] The difference between the two methods is that, for the first method, regardless of the value of the specified bit in the sixth bit, the fourth bit or the fifth bit is determined based on the specified bit. For the second method, the fourth bit or the fifth bit is determined based on the specified bit only when the specified bit is the first specified value.

[0079] It should be noted that when determining the fourth or fifth bit based on a specified bit in the sixth bit, that specified bit can be used as the most significant bit, the least significant bit, or the most significant or least significant bit of the final determined first or second target bit. This can be configured by the network-side device or predefined by the protocol; no specific limitations are made here.

[0080] Taking the third bit as an example of 6 bits, and assuming the sixth bit is the first 2 bits, the second mapping relationship (i.e. the mapping relationship between the value of the sixth bit and the number of the eighth and ninth bits) can be represented by Table 2 below.

[0081] Table 2

[0082] The value of the sixth bit Number of eighth bits Number of ninth bits 00 0 4 01 1 3 10 2 2 11 3 1

[0083] In Table 2, the rightmost bit of the sixth bit can be used as the specified bit mentioned above, and the value 1 can be used as the first specified value mentioned above. Thus, taking the sixth bit as having values ​​of 00 and 01 as an example:

[0084] When determining the fourth and fifth bits based on the first method described above, if the sixth bit is 00, then the rightmost bit of the sixth bit can be used as the fourth bit, and the remaining four bits of the third bit (i.e., the ninth bit) can be used as the fifth bit; or the rightmost bit of the sixth bit can be used as the fifth bit, and the remaining four bits of the third bit (i.e., the ninth bit) can be used as the fourth bit. If the sixth bit is 01, then the rightmost bit of the sixth bit and the first or last bit of the remaining four bits of the third bit (i.e., the eighth bit) can be used as the fourth bit, and the remaining three bits (i.e., the ninth bit) can be used as the fifth bit; or the rightmost bit of the sixth bit and the first three or last three bits of the remaining four bits of the third bit (i.e., the ninth bit) can be used as the fourth bit, and the remaining bit (i.e., the eighth bit) can be used as the fifth bit.

[0085] When determining the fourth and fifth bits based on the second method described above, if the sixth bit is 00, then the remaining four bits of the third bit (i.e., the ninth bit) can be used as the fifth bit, and the number of fourth bits is 0; or the remaining four bits of the third bit (i.e., the ninth bit) can be used as the fourth bit, and the number of fifth bits is 0. If the sixth bit is 01, then the rightmost bit of the sixth bit and the first or last bit of the remaining four bits of the third bit (i.e., the eighth bit) can be used as the fourth bit, and the remaining three bits (i.e., the ninth bit) can be used as the fifth bit; or the rightmost bit of the sixth bit and the first three or last three bits of the remaining four bits of the third bit (i.e., the ninth bit) can be used as the fourth bit, and the remaining one bit (i.e., the eighth bit) can be used as the fifth bit.

[0086] Of course, the number of eighth bits and ninth bits in Table 2 above are only illustrative examples. In other implementations, there may be other numbers, which will not be listed here.

[0087] S2043: Determine the first bit and the fourth bit as the first target bit, and determine the second bit and the fifth bit as the second target bit.

[0088] After determining the fourth and fifth bits in S2042, the first and fourth bits can be designated as the first target bits, and the second and fifth bits as the second target bits. Therefore, through S2041 to S2043, based on the first indication method indicated by the configuration information issued by the network-side device, the first target bits for indicating the number of uplink time slots and the second target bits for indicating the number of downlink time slots can be determined.

[0089] When the terminal determines the first target bit and the second target bit based on the aforementioned second indication method, it can determine the first target bit and the second target bit based on the first indication field and the second indication field in the configuration information. The second indication field may include a predetermined number of bits, the sum of which, along with the number of bits in the first indication field, can equal the total number of bits required by the existing time slot configuration method to indicate the number of uplink and downlink transmission time slots. For example, in a format indicating 640 time slots (corresponding to an SCS of 960 kHz and a transmission period of 10 ms), when using the existing time slot configuration method, 10 bits are needed to indicate the number of uplink transmission time slots, and 10 bits are needed to indicate the number of downlink transmission time slots. If the first indication field includes 18 bits, then the predetermined number of bits in the second indication field is 2 bits.

[0090] When determining the first target bit and the second target bit based on the first indication field and the second indication field, the first target bit and the second target bit can be determined from multiple bits obtained by combining the first indication field and the second indication field using a third method. Specifically, the first target bit and the second target bit do not overlap in the multiple bits obtained by combining them, and the sum of the number of first target bits and the number of second target bits is equal to the total number of bits obtained by combining them. The third method can be pre-configured by the network-side device or pre-defined by the protocol, and the positions of the first target bit and the second target bit in the multiple bits obtained by combining them can also be pre-configured by the network-side device or pre-defined by the protocol. Optionally, the network-side device and the protocol can configure or define the positions of the first target bit and the second target bit in the multiple bits obtained by combining them using the aforementioned third method; that is, the terminal can determine which specific bit in the multiple bits obtained by combining them is the first target bit and which bit is the second target bit based on the third method.

[0091] Taking an example where the first indication field includes 18 bits and the second indication field includes 2 bits, when indicating the format of 640 time slots, the third method can instruct that the first 9 bits of the first indication field and the first bit of the second indication field are determined as the first target bit, and the remaining 9 bits of the first indication field and the other bit of the second indication field are determined as the second target bit. Alternatively, the third method can also instruct that the first 10 bits of the first indication field are determined as the first target bit, and the remaining 8 bits of the first indication field and the 2 bits of the second indication field are determined as the second target bit. Alternatively, the third method can only indicate the number of bits, with the specific position of the bits configured by the network-side device or predefined by the protocol.

[0092] S206: Determine the number of uplink transmission time slots based on the first target bit, and determine the number of downlink transmission time slots based on the second target bit.

[0093] After the terminal determines the first target bit and the second target bit in the manner described in S204, it can determine the number of uplink transmission time slots based on the first target bit and the number of downlink transmission time slots based on the second target bit.

[0094] For example, if a network-side device needs to indicate the format of 640 time slots, and the first indication field includes 18 bits, then, when the terminal determines the first target bit and the second target bit based on the first indication method, if the first bit has 6 bits, the second bit has 6 bits, the fourth bit of the third bit has 2 bits, and the fifth bit has 1 bit, then the number of first target bits is 8 and the number of second target bits is 7. Assuming the value of the first target bit is 01000010 and the value of the second target bit is 0010101, then the number of uplink transmission time slots is 67, the number of downlink transmission time slots is 22, and the remaining time slots can be flexible time slots. Specifically, the 67 uplink transmission time slots can be 67 consecutive time slots starting from the last time slot, and the 22 downlink transmission time slots can be 22 consecutive time slots starting from the first time slot, with the intermediate time slots all being flexible time slots.

[0095] In this embodiment, when configuring the time slot format, the network-side device can send configuration information including a first indication field to the terminal. This configuration information is used to indicate the number of uplink and downlink time slots through a first indication method or a second indication method. The first indication method involves dividing multiple bits in the first indication field into multiple groups of bits and using these multiple groups of bits for joint indication. The second indication method involves the first indication field combined with other fields for joint indication. Thus, when the number of time slots is large, by dividing the existing number of bits into multiple groups of bits and using these groups of bits to jointly indicate the number of time slots in different formats, or by adding new bits and combining them with the existing number of bits to jointly indicate the number of time slots in different formats, effective indication of the number of time slots in different formats can be achieved, thereby enabling effective configuration of the format of each time slot.

[0096] like Figure 3 As shown in the figure, this application embodiment provides a time slot configuration method 300, which can be executed by a network-side device. In other words, the method can be executed by software or hardware installed on the network-side device, and the method includes the following steps.

[0097] S302: The network-side device sends configuration information; wherein the configuration information includes a first indication field, the configuration information is used to indicate a first target bit and a second target bit through a first indication method or a second indication method, the first target bit is used to indicate the number of uplink transmission time slots, the second target bit is used to indicate the number of downlink transmission time slots, the first indication method includes dividing multiple bits in the first indication field into multiple groups of bits, and using multiple groups of bits for joint indication, the second indication method includes the first indication field combined with other fields for joint indication.

[0098] When configuring the timeslot format, the network-side device can send configuration information to the terminal. This configuration information is used to indicate the number of bits (i.e., the first target bits) used to indicate the number of timeslots for uplink transmission and the number of bits (i.e., the second target bits) used to indicate the number of timeslots for downlink transmission, either through a first indication method or a second indication method.

[0099] The configuration information described above may include a first indication field, which may consist of one indication field or multiple indication fields. The first indication method can be understood as, without increasing the number of bits, changing the way bits are indicated—that is, changing how the terminal interprets bits—to achieve the purpose of using existing multiple bits to indicate the format of more time slots. Specifically, it involves grouping existing multiple bits and using the grouped bits for joint indication. The second indication method can be understood as adding multiple bits to the existing multiple bits to jointly indicate the number of uplink and downlink transmission time slots. For a detailed understanding of the first indication field, the first indication method, and the second indication method, please refer to [link to relevant documentation]. Figure 2 The corresponding content in the illustrated embodiments will not be repeated here.

[0100] When the configuration information is used to indicate the first target bit and the second target bit through the first indication method, the first target bit and the second target bit are included in the multiple bits of the first indication field, the first target bit and the second target bit do not overlap, and the sum of the number of the first target bit and the second target bit is less than or equal to the total number of multiple bits.

[0101] The aforementioned first indication method is used to indicate non-overlapping first, second, and third bits among a plurality of bits, and to indicate non-overlapping fourth and fifth bits among the third bits, wherein the number of fourth and fifth bits can be zero or one or more. The sum of the number of first, second, and third bits is equal to the total number of bits in the first indication field. The first target bit includes the first and fourth bits, and the second target bit includes the second and fifth bits.

[0102] The first method described above can be pre-configured by the network-side device or pre-defined by the protocol. The positions of the first bit, the second bit, and the third bit among the multiple bits of the first indication field are pre-configured by the network-side device or pre-defined by the protocol. Optionally, the network-side device and the protocol can indicate the positions of the first bit, the second bit, and the third bit among the multiple bits of the first indication field using the first method, so that the terminal can determine which bits are the first bit, which bits are the second bit, and which bits are the third bit among the multiple bits of the first indication field based on the first method.

[0103] The second method described above can be pre-configured by the network-side device or pre-defined by the protocol. The positions of the fourth and fifth bits within the third bit are pre-configured by the network-side device or pre-defined by the protocol. Optionally, the network-side device and the protocol can indicate the positions of the fourth and fifth bits within the third bit through the second method, so that the terminal can determine not only the number of each of the fourth and fifth bits, but also their specific positions within the third bit based on the second method.

[0104] In this embodiment, the second method is specifically used to determine the sixth bit from the third bit, and the sixth bit is used to indicate the fourth and fifth bits. Determining the sixth bit from the third bit can mean determining which specific bit in the third bit is the sixth bit. When indicating the fourth and fifth bits using the sixth bit, this can be achieved through at least the following two implementation methods.

[0105] In one implementation, the sixth bit is used to indicate the fourth and fifth bits through a first mapping relationship. The first mapping relationship is a mapping between the value of the sixth bit and the number of fourth and fifth bits, where the fourth and fifth bits are the other bits in the third bit set excluding the sixth bit.

[0106] Taking the network-side device indicating that the third bit is 6 bits as an example, and assuming that the network-side device also indicates that the sixth bit is the first two bits of the third bit, then the first mapping relationship (that is, the mapping relationship between the value of the sixth bit and the number of the fourth bit and the number of the fifth bit) can be represented by Table 3 below.

[0107] Table 3

[0108] The value of the sixth bit Number of fourth bits Number of fifth bits 00 0 4 01 1 3 10 2 2 11 3 1

[0109] As shown in Table 3, when the sixth bit is 00, it indicates that all remaining bits of the third bit are used as the fifth bit, and the number of fourth bits is 0. When the sixth bit is 01, it indicates that the first or last bit of the remaining bits of the third bit is used as the fourth bit, and the remaining three can be used as the fifth bit. When the sixth bit is 10, it indicates that the first two or last two bits of the remaining bits of the third bit are used as the fourth bit, and the remaining two can be used as the fifth bit. When the sixth bit is 11, it indicates that the first three or last three bits of the remaining bits of the third bit are used as the fourth bit, and the remaining one is used as the fifth bit.

[0110] Of course, in other implementations, when the value of the sixth bit is 00 / 01 / 10 / 11, the number of the fourth and fifth bits indicated by the sixth bit in Table 3 above can also be other numbers, which will not be illustrated here.

[0111] In another implementation, the sixth bit can indicate whether the fourth or fifth bit is determined based on a specified bit within the sixth bit. Specifically, in the first implementation, the sixth bit can be used to indicate that the eighth bit from the seventh bit and a specified bit from the sixth bit are determined as the fourth bit, and the ninth bit from the seventh bit are determined as the fifth bit, or the eighth bit is determined as the fourth bit, and the ninth bit and a specified bit from the sixth bit are determined as the fifth bit. In the second implementation, the sixth bit is used to determine the eighth bit and a specified bit as the fourth bit, and the ninth bit as the fifth bit, or the eighth bit is determined as the fourth bit, and the ninth bit and a specified bit are determined as the fifth bit, when the specified bit has a first specified value. Here, the seventh bit refers to all bits in the third bit group except the sixth bit; the eighth and ninth bits do not overlap; there is a second mapping relationship between the number of eighth bits, the number of ninth bits, and the value of the sixth bit; and the sum of the number of eighth and ninth bits is less than the total number of seventh bits. The indication of the eighth and ninth bits here can indicate which specific bit is the eighth and ninth bit.

[0112] The specified bit in the sixth bit can be one or more bits in the sixth bit, which can be pre-configured by the network-side device or pre-defined by the protocol. Optionally, when the number of sixth bits is fixed, the above second mapping relationship can be the same as the above first mapping relationship (the number of eighth bits is equal to the number of fourth bits, the number of ninth bits is equal to the number of fifth bits, or the number of eighth bits is equal to the number of fifth bits, and the number of ninth bits is equal to the number of fourth bits).

[0113] In addition, when the network-side device indicates that a specified bit in the sixth bit is the fourth bit or the fifth bit, it can also indicate or be predefined by the protocol whether the specified bit is the most significant bit or the least significant bit of the fourth / fifth bit, or it can also indicate whether the specified bit is the most significant bit or the least significant bit of the first / second target bit that is finally determined.

[0114] Taking the third bit as an example of 6 bits, assuming that the network-side device indicates that the sixth bit is the first 2 bits of the third bit, the second mapping relationship (that is, the mapping relationship between the value of the sixth bit and the number of the eighth bit and the number of the ninth bit) can be represented by Table 4 below.

[0115] Table 4

[0116] The value of the sixth bit Number of eighth bits Number of ninth bits 00 0 4 01 1 3 10 2 2 11 3 1

[0117] Table 4 indicates that the rightmost bit of the sixth bit is the specified bit mentioned above, with the value 1 being the first specified value. Thus, taking the sixth bit as 00 or 01 as an example:

[0118] When indicating the fourth and fifth bits based on the first method described above, if the sixth bit is 00, then the sixth bit is used to indicate that the rightmost bit of the sixth bit is used as the fourth bit, and the remaining four bits of the third bit (i.e., the ninth bit) are used as the fifth bit, or it is used to indicate that the rightmost bit of the sixth bit is used as the fifth bit, and the remaining four bits of the third bit (i.e., the ninth bit) are used as the fourth bit. If the sixth bit is 01, then the sixth bit is used to indicate that the rightmost bit of the sixth bit and the first or last bit of the remaining four bits of the third bit (i.e., the eighth bit) are used as the fourth bit, and the remaining three bits (i.e., the ninth bit) are used as the fifth bit, or it is used to indicate that the rightmost bit of the sixth bit and the first three or last three bits of the remaining four bits of the third bit (i.e., the ninth bit) are used as the fourth bit, and the remaining one bit (i.e., the eighth bit) is used as the fifth bit.

[0119] When indicating the fourth and fifth bits based on the second method described above, if the sixth bit is 00, then the sixth bit is used to indicate that the remaining 4 bits of the third bit (i.e., the ninth bit) are used as the fifth bit, and the number of fourth bits is 0; or it is used to indicate that the remaining 4 bits of the third bit (i.e., the ninth bit) are used as the fourth bit, and the number of fifth bits is 0. If the sixth bit is 01, then the sixth bit is used to indicate that the rightmost bit of the sixth bit and the first or last bit of the remaining 4 bits of the third bit (i.e., the eighth bit) are used as the fourth bit, and the remaining 3 bits (i.e., the ninth bit) are used as the fifth bit; or it is used to indicate that the rightmost bit of the sixth bit and the first or last 3 bits of the remaining 4 bits of the third bit (i.e., the ninth bit) are used as the fourth bit, and the remaining 1 bit (i.e., the eighth bit) is used as the fifth bit.

[0120] Of course, the number of eighth bits and the number of ninth bits indicated by the sixth bit in Table 4 above are only illustrative examples. In other implementations, other numbers can also be indicated, which will not be illustrated here.

[0121] When the network-side device indicates the first target bit and the second target bit through the aforementioned second indication method, the configuration information also includes a second indication field. Therefore, the network-side device indicates the first target bit and the second target bit through the second indication method, specifically by the first indication field and the second indication field working together.

[0122] The second indicator field and the first indicator field can belong to the same indicator domain, meaning the second indicator field is a newly added field within the indicator domain containing the first indicator field. Alternatively, the second indicator field can belong to a different indicator domain than the first indicator field. The indicator domain to which the second indicator field belongs can be a newly added indicator domain, or it can be an available field within a specified indicator domain. This specified indicator domain can be configured by the network-side device or predefined by the protocol. Optionally, this specified indicator domain can be nrofUplinkSymbols or nrofDownlinkSymbols in the existing TDD-UL-DL-ConfigurationCommon configuration.

[0123] It should be noted that when indicating the first target bit and the second target bit, the network-side device can indicate them using either a first indication method or a second indication method. The specific indication method used can be determined by the network-side device or predefined according to the protocol. Optionally, under the condition that a first preset condition is met, the network-side device can indicate the first target bit and the second target bit using the second indication method.

[0124] The first preset condition mentioned above includes at least one of the following: the transmission frequency range of SIB1 is a specified frequency (e.g., FR2 / FR2-2), the SCS is a specified frequency (e.g., 960KHz), and the transmission period of the uplink / downlink is a specified period (e.g., 10ms).

[0125] The second indication field may include a set number of bits. When the network-side device indicates the first target bit and the second target bit using the second indication method, specifically, the second indication method is used to indicate the first target bit and the second target bit using a third method. The first target bit and the second target bit do not overlap in the multiple bits obtained by combining the first and second indication fields, and the sum of the number of the first target bit and the second target bit is equal to the total number of bits obtained by the combination. The third method is pre-configured by the network-side device or pre-defined by the protocol. The positions of the first target bit and the second target bit in the multiple bits obtained by the combination are pre-configured by the network-side device or pre-defined by the protocol. Optionally, the network-side device and the protocol can configure or define the positions of the first target bit and the second target bit in the multiple bits obtained by the combination using the aforementioned third method, so that the terminal can determine, based on the third method, which specific bit in the multiple bits obtained by combining the first and second indication fields is the first target bit and which bit is the second target bit. See [link to documentation] for details. Figure 2 The corresponding content in the illustrated embodiments will not be described again here.

[0126] In this embodiment, after the network-side device sends configuration information to the terminal, the terminal can determine the first target bit and the second target bit based on the configuration information. The specific implementation of the terminal determining the first target bit and the second target bit can be found in [reference needed]. Figure 2 The embodiments shown will not be described again here.

[0127] In this embodiment, when configuring the time slot format, the network-side device can send configuration information including a first indication field to the terminal. This configuration information is used to indicate the number of uplink and downlink time slots through a first indication method or a second indication method. The first indication method involves dividing multiple bits in the first indication field into multiple groups of bits and using these multiple groups of bits for joint indication. The second indication method involves the first indication field combined with other fields for joint indication. Thus, when the number of time slots is large, by dividing the existing number of bits into multiple groups of bits and using these groups of bits to jointly indicate the number of time slots in different formats, or by adding new bits and combining them with the existing number of bits to jointly indicate the number of time slots in different formats, effective indication of the number of time slots in different formats can be achieved, thereby enabling effective configuration of the format of each time slot.

[0128] It should be noted that the time slot configuration method provided in this application can be executed by a time slot configuration device or a control module in the time slot configuration for executing the time slot configuration method. This application uses the execution of the time slot configuration method by a time slot configuration device as an example to illustrate the time slot configuration device provided in this application.

[0130] The receiving module 401 is used to receive configuration information, which includes a first indication field.

The first target bit is used to indicate the number of uplink transmission time slots, and the second target bit is used to indicate the number of downlink transmission time slots. The first indication method includes dividing multiple bits in the first indication field into multiple groups of bits and performing joint indication through the multiple groups of bits.
