It will be appreciated that the terminal devices to which embodiments of the present application relate may be devices for providing voice and/or data connectivity to a user, handheld devices having wireless connection capability, or other processing devices connected to a wireless modem. The terminal equipment may also be a wireless terminal, wherein the wireless terminal may communicate with one or more core networks via a Radio Access Network (RAN), and the wireless terminal may be a mobile terminal such as a mobile telephone (or referred to as a "cellular" telephone), or a computer having a mobile terminal, for example, a portable, pocket, hand-held, computer-included, or vehicle-mounted mobile device, which exchanges language and/or data with the RAN. For example, the wireless terminal may be a Personal Communication Service (PCS) phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), or the like. A wireless terminal may also be referred to as a system, a subscriber unit (subscriber unit), a subscriber station (subscriber station), a mobile station (mobile), a remote station (remote station), an Access Point (AP), a remote terminal (remote terminal), an access terminal (access terminal), a user terminal (user terminal), a user agent (user agent), a user equipment (user device), or a User Equipment (UE), and the like, which are not limited in the embodiments of the present application.

The embodiment of the present application is not limited to this.
Some terms of the embodiments of the present application are explained below.
Frequency domain resource unit: the unit of the resource in the time slot format indicated to the terminal device by the network device on the frequency domain may be CC, BWP, carrier band (carrier band), or the like, which is not limited in this embodiment of the application. The BWP in the embodiment of the present application may be a continuous frequency domain resource or a discontinuous frequency domain resource.
Time slot: also called slot, a unit of resource for transmitting data in time domain, a slot usually contains multiple symbols/chips, and each symbol/chip may have the same or different transmission direction.
The configuration parameter, which may also be referred to as numerology, includes a subcarrier interval, a type of a time unit, or a Cyclic Prefix (CP), where it should be noted that the configuration parameter may include at least one of the subcarrier interval, the type of the time unit, and the CP, and may further include other parameters such as a Fast Fourier Transform (FFT) point number, which is not limited in this embodiment. Specifically, the configuration parameters are parameters for describing frequency domain resource units, and different configuration parameters corresponding to the frequency domain resource units may cause different time domain widths of the symbols. Taking the subcarrier spacing as an example, if the subcarrier spacing corresponding to the frequency domain resource unit is 15 kilohertz (KHz), the time domain width of one symbol is 1/15000 seconds(s), and if the subcarrier spacing corresponding to the frequency domain resource unit is 30KHz, the time domain width of one symbol is 1/30000s, in NR, when the subcarrier spacing (subcarrier spacing) is less than or equal to 60KHz, the number of symbols included in each slot is 7 or 14; when the subcarrier spacing is >60KHz, the number of symbols included per slot is 14.
The slot format, also called slot format, is used to indicate the transmission direction of each symbol/chip on a slot, or information such as content carried on one or more symbols/chips by a terminal device. For example, the slot format shown in fig. 2: DL format0, DL format1, DL format2, DL format3, UL format0, UL format1, and UL format2, wherein the slot format shown in fig. 2 is only an example, in an actual communication system, only a part or all of the slot format shown in fig. 2 may be used, and other types of slot formats may also be used, which is not limited in the embodiment of the present application.
The time slot format set comprises at least one time slot format and is obtained by dividing all time slot formats used in the communication system according to a certain rule. For example, assuming that the slot format used in the communication system is as shown in fig. 2, when the division rule indicates that transmission directions of any two slot formats belonging to the same slot format set respectively at the same time domain position do not collide, the slot format shown in fig. 2 may be divided into a slot format set 1 and a slot format set 2, where the slot format set 1 includes DL format0, DL format1, DL format2, and DL format3, and the slot format set 2 includes UL format0, UL format1, and UL format2, and taking DL format0, DL format1, DL format3, and UL format0 as examples, DL format0 and DL format1 both transmit downlink data at time domain position a, DL format3 is empty at time domain position a, that is, no data is transmitted at time domain position a, and UL format0 transmits uplink data at time domain position a, therefore, the transmission directions of DL format0, DL format1 and UL format0 at time domain position a collide, the transmission directions of DL format0, DL format1 and DL format3 at time domain position a do not collide, however, since DL format3 is empty at time domain position a, the transmission directions of DL format3 and UL format0 at time domain position a do not conflict, whereas DL format3 transmits downlink data at time domain position B, UL format0 transmits uplink data at time domain position B, therefore the transmission directions of DL format3 and UL format0 at time domain position B collide, therefore DL format3 and UL format0 belong to different slot format sets, while the transmission directions of the DL format0, DL format1 and DL format3 at any time domain position do not collide, therefore, DL format0, DL format1 and DL format3 belong to the same slot format set.
In addition, it should be further noted that, in the embodiment of the present application, the division of the slot format set is not limited to the above-mentioned division rule, and the example may also be based on the alignment condition of the control signal region, so long as the symbol positions carrying the control data in each slot format on one slot are aligned and do not collide, the slot format set may be divided into the same slot format set. Taking the slot format shown in fig. 2 as an example, if the transmission directions at the time domain positions for transmitting the uplink control information and the downlink control information do not conflict, the slot format shown in fig. 2 is divided into a slot format set a and a slot format set b, where the slot format set a includes DL format0, DL format2, DL format3, UL format0, UL format1 and UL format2, and the slot format set b includes DL format 1. Or the division of the slot format set is divided according to the alignment relation of symbols among different numerologies, and the like. Taking numerology including subcarrier spacing as an example, different subcarrier spacings may result in different time domain widths of symbols, and it may be predefined which time domain positions of the time slot formats of the frequency domain resource units corresponding to different subcarrier spacings cannot collide with each other, for example, the first symbol in the time slot format of the frequency domain resource unit corresponding to the subcarrier spacing of 15KHz does not collide with the transmission directions of the first two symbols in the time slot format of the frequency domain resource unit corresponding to the subcarrier spacing of 30 KHz. However, no matter how the slot format set is divided, the indication mode of the slot format in the embodiment of the present application is applicable.
The frequency domain resource unit is taken as BWP for example to describe in detail below, and when the frequency domain resource unit is CC or other frequency domain resource for transmitting information, it is similar to when the frequency domain resource unit is BWP, and is not described herein again.
As shown in fig. 3, a method for indicating a slot format according to an embodiment of the present application includes:
in step 300, the network device determines first indication information and second indication information, where the first indication information is used to indicate a slot format set, the slot format set includes a first slot format, the second indication information is used to indicate the first slot format, the first slot format is a slot format of a first BWP, and the first BWP is configured by the network device to the first terminal device for communication.
Step 301, the network device sends the first indication information and the second indication information to the first terminal device.
Step 302, after receiving the first indication information and the second indication information sent by the network device, the first terminal device determines the slot format of the first BWP according to the first indication information and the second indication information.
It should be noted that, in this embodiment of the present application, the first indication information and the second indication information may be carried in one signaling message, or the first indication information and the second indication information are respectively carried in different signaling messages, which is not limited in this embodiment of the present application.
For example, the first indication information and the second indication information may be carried in a Radio Resource Control (RRC) signaling, a Medium Access Control (MAC) signaling, or a Downlink Control Information (DCI) signaling, and the embodiment of the present invention is not limited thereto.
In addition, the first indication information may be carried in MAC or DCI signaling of the main frequency domain resource unit or the reference frequency domain resource unit, and the second indication information may be carried in DCI signaling of each frequency domain resource unit, or the first indication information may be carried in MAC or DCI signaling of the main frequency domain resource unit or the reference frequency domain resource unit, and the second indication information may be carried in MAC or DCI signaling of the main frequency domain resource unit or the reference frequency domain resource unit, and the like. The primary frequency domain resource unit or the reference frequency domain resource unit is a frequency domain resource configured by the network device to the terminal device as a reference configuration of all frequency domain resource units, or the primary frequency domain resource unit or the reference frequency domain resource unit is a frequency domain resource unit in which the terminal device is located when the terminal device first accesses the network, or the primary frequency domain resource unit or the reference frequency domain resource unit is a frequency domain resource in which a group common Physical Downlink Control Channel (PDCCH) is located, wherein the group common PDCCH is a channel for transmitting a group of terminal device control information. The frequency domain resource unit is a frequency domain resource configured by the network device for data transmission to the terminal device, for example, a frequency domain resource in which a Physical Downlink Shared Channel (PDSCH) or a Physical Uplink Shared Channel (PUSCH) is located.
For example, the first indication information is carried in group common DCI, and the second indication information is carried in specific DCI, so that when the slot format sets of multiple BWPs belong to the same slot format set, the first indication information may be sent to multiple terminal devices through group common DCI, where the multiple terminal devices are terminal devices configured with at least one BWP of the multiple BWPs.
In the embodiment of the present application, since the slot format of the BWP may be indicated by the first indication information and the second indication information together, the first indication information may indicate a common part of the slot format of the BWP, and the second indication information may indicate a specific part of the BWP, when the network device configures multiple BWPs for one or more terminal devices in a cell, the network device may indicate the slot formats of multiple BWPs by sending the first indication information and the second indication information, which may help to reduce the number of bits of information used for indicating the slot format and save overhead of the system.
The following describes the method for indicating the timeslot format in this embodiment in detail by taking a TDD system as an example.
In a TDD system, uplink communication and downlink communication cannot be performed simultaneously at a certain time point (e.g. a symbol in a slot) in a frequency band. Therefore, in the TDD system, all slot formats used in the TDD system can be divided according to a rule that transmission directions located at the same time domain position do not collide. The time slot format used in the TDD system is exemplified by the time slot format shown in fig. 2, but the time slot format shown in fig. 2 is not limited in the communication system. When the time slot format set 1 and the time slot format set 2 are obtained by dividing according to a rule that transmission directions located at the same time domain position do not conflict, wherein the time slot format set 1 includes DL format0, DL format1, DL format2 and DL format3, and the time slot format set 2 includes UL format0, UL format1 and UL format 2.
It is assumed that in slot1, the network device configures BWP1 and BWP2 for end device 1, the network device configures BWP3, BWP4 and BWP5 for end device 2, and the network device configures BWP6 for end device 3, where BWP1, BWP2, BWP3, BWP4, BWP5 and BWP6 may or may not overlap each other. If the slot format of BWP1, the slot format of BWP2, the slot format of BWP3, the slot format of BWP4, the slot format of BWP5, and the BWP6 are all suitable to belong to slot format set 1 on slot1, the first indication information is used to indicate slot format set 1, the first indication information may be identification information of slot format set 1, such as a serial number, an enumerated value, or the like, and the network device may send the first indication information to terminal device 1, terminal device 2, and terminal device 3 in a multicast or broadcast manner, and then only needs to send the first indication information once at the network device, and terminal device 1, terminal device 2, and terminal device 3 can all obtain the first indication information without repeatedly sending the first indication information many times, thereby helping to reduce signaling overhead in the system.
For the second indication information, assuming that the slot format of BWP1 is DL format0, the slot format of BWP2 is DL format1, the slot format of BWP3 is DL format3, the slot format of BWP4 is DL format0, the slot format of BWP5 is DL format2, and the slot format of BWP6 is DL format1, since slot format set 1 includes 4 types of slot formats, it should be noted that the slot format set 1 may indicate different slot formats through 2-bit information, and on slot1, the slot format of BWP configured by the network device to the terminal device may also use only a part of slot formats in slot format set 1, for example, the network device configures BWP0 to terminal device a and also configures BWP0 to terminal device b, where the slot format of BWP0 configured by terminal device a is DL format1, and the slot format of BWP0 configured by terminal device 2 is DLformat0, the timeslot format set 1 includes DL format0, DL format1, DL format2, and DL format3, and the BWP configured by the network device to the terminal device only uses two timeslot formats in the timeslot format set 1.
One possible implementation is: each of the second indication information is used to indicate a slot format of a BWP, when all the second indication information is sent to the terminal device 1, the terminal device 2, and the terminal device 3 in a signaling message, in order to enable different terminal devices to determine which second indication information is used to indicate the slot format of the BWP configured by the network device to itself, the order of the second indication information may be agreed in advance, or the network device notifies the terminal device of the order of the second indication information in advance, which is not limited in this embodiment of the present application, for example, the second indication information is carried in the first signaling message, where the second indication information is arranged sequentially from left to right according to the order of BWP1, BWP2, BWP3, BWP4, BWP5, and BWP6, and after receiving the first signaling message, the terminal device 1 only needs to parse the second indication information at the first position and the second position from left to right in the first signaling message, the second indication information at other locations need not be parsed. In this case, in order to reduce the overhead of signaling, the network device may send the first signaling message to the terminal device in a multicast or broadcast manner, so that the network device sends the first signaling message once, and the terminal device 1, the terminal device 2, and the terminal device 3 may all obtain the first signaling message. In this case, therefore, since the first indication information may be indicated by 1-bit information and each second indication information may be indicated by 2-bit information, the indication information of the slot formats of BWPs 1-BWP 6 may be indicated by (1+2+2+2+ 2) bits, which reduces the signaling overhead of the system compared to the prior art in which 3-bit information is used alone to indicate a slot format of a BWP.
In addition to this, the second indication information may also be directly transmitted to the corresponding terminal device, for example, the second indication information indicating the slot format of BWP1 and the second indication information indicating the slot format of BWP2 in the second indication information may be directly transmitted to terminal device 1 without being transmitted to other terminal devices.
It should be noted that, in the embodiment of the present application, the same BWP may be configured to multiple terminal devices, and the slot format of the BWP needs to be indicated to the terminal devices respectively. For example, the network device configures BWP1 to both terminal device 1 and terminal device 2, but on slot1, the slot format of BWP1 is DLformat0 for terminal device 1, and the slot format of BWP1 is DL format1 for terminal device 2, and at this time, it needs to indicate the slot formats of BWP1 to terminal device 1 and terminal device 2, respectively.
In addition, in order to save the overhead of the signaling message, since the slot format of BWP1 and the slot format of BWP4 are both DL format0, and the slot format of BWP2 and the slot format of BWP6 are both DL format1, another possible implementation manner is: the slot format of BWP1 and the slot format of BWP4 may be indicated by one second indication information, and the slot format of BWP2 and the slot format of BWP6 may be indicated by another second indication information. Specifically, BWP1 is configured by the network device to terminal device 1, BWP2 is configured by the network device to terminal device 2, and the slot format of BWP1 and the slot format of BWP2 are both indicated by the second indication information indicating DL format0, so that the network device needs to send the second indication information to both terminal device 1 and terminal device 2, and the second indication information may be sent to terminal device 1 and terminal device 2 in a multicast or broadcast manner. In this case, optionally, when all the second indication information is carried in one signaling message to be sent, for example, the second indication information is carried in the first signaling message, since the slot format of BWP1 and the slot format of BWP4 are both DL format0, the slot format of BWP2 and the slot format of BWP6 are both DL format1, where the second indication information is arranged in the order of BWP1/BWP4, BWP2/BWP6, BWP3, and BWP from left to right, and the network device agrees in advance with the arrangement order of the second indication information in the first signaling message by the terminal device, or notifies the terminal device in advance of the arrangement order of the second indication information in the first signaling message, so that the terminal device can read the second indication information belonging to itself from the first signaling message.
Further, when the slot format of BWP1 and the slot format of BWP2 configured by the network device to the terminal device 1 are the same, in order to enable the terminal device 1 to know which slot formats indicated by the second indication information correspond to multiple BWPs, optionally, the network device sends third indication information to the terminal device, where the third indication information is used to indicate at least two BWPs corresponding to the same slot format in the slot format set. For example, BWP1 and BWP2 correspond to DLformat0 in slot format set 1, respectively, and the third indication information is used to indicate BWP1 and BWP 2.
Further, in NR, each BWP corresponds to a configuration parameter, where the configuration parameter includes a subcarrier interval, a type of a time unit, or a Cyclic Prefix (CP) type, etc.; when the BWP configuration parameters are the same, the slot formats of the BWPs are the same, and the terminal device may determine which BWPs have the same slot format according to the BWP configuration parameters.
Specifically, as shown in fig. 4, BWP1 corresponds to a subcarrier interval of 30KHz, BWP2, BWP3 correspond to a subcarrier interval of 15KHz, respectively, since the time domain width of each symbol is 1/30000 seconds(s) when the subcarrier interval is 30KHz and the time domain width of each symbol is 1/15000s when the subcarrier interval is 15KHz, when the number of symbols included in one slot is the same as the number of symbols included in one slot when the subcarrier interval is 15KHz, the slot when the subcarrier interval is 15KHz corresponds to 2 slots when the subcarrier interval is 30KHz, if the slot when the subcarrier interval is 15KHz is the first slot, the slot when the subcarrier interval is 30KHz is the second slot, and since the slot format of BWP is the slot format of BWP on one slot, different time domain subcarrier intervals may have different widths, therefore, in order to ensure the integrity of each slot, in the embodiment of the present application, the slot used by the slot format indication information is taken as the slot with the largest time domain width among all slots, or is taken as the least common multiple of the time domain widths of all slots, and in the above case, the slot is the first slot. Taking fig. 4 as an example, in addition to using the first indication information to indicate the slot format set, for BWP1, since 2 second slots are included in one first slot, it is necessary to indicate the slot format of BWP1 on the first second slot and indicate the slot format of BWP1 on the second slot.
Since in this case, the slot formats corresponding to the BWPs corresponding to the same configuration parameter are usually the same, but in some special cases, there may be a case where the slot formats corresponding to the BWPs corresponding to the same configuration parameter are different, in order to make the terminal device know which slot formats corresponding to the same BWPs are different, when the network device configures the first BWP and the second BWP to the terminal device, where the configuration parameters corresponding to the first BWP and the second BWP are the same, but the slot format of the first BWP is different from the slot format of the second BWP, optionally, the network device sends fourth indication information to the terminal device, where the fourth indication information is used to indicate the first BWP and the second BWP. For example, the fourth indication information may be identification information of the first BWP and the second BWP.
It should be noted that, when at least three BWPs exist in at least one BWP and correspond to the configuration parameter 1, but the slot formats corresponding to the at least three BWPs are different, the fourth indication information is used to indicate the at least three BWPs.
It should be further noted that, in the embodiment of the present application, in addition to indicating the slot format corresponding to the BWP on the current slot, the slot format corresponding to the current slot and the BWP on the subsequent multiple slots may also be indicated, where the manner of indicating the slot format is similar to that of indicating the slot format described above.
