Communication method, device, chip and module equipment

[0001] This application claims priority to the Chinese patent application with application number 202311048880.5 filed with the State Intellectual Property Office of China on August 18, 2023, and priority to the Chinese patent application with the invention name “A communication method, device, chip and module equipment”, all contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communications, and in particular to a communication method, apparatus, chip, and module equipment. Background Art

[0003] In communications technology, network devices can use time division duplex (TDD) communication. When using TDD, a time slot can be used for either uplink or downlink transmission. Generally, network devices configure a TDD frame structure for terminal devices, allowing them to use the time domain resources within the TDD frame structure for data transmission. However, this single uplink and downlink time slot ratio can result in significant transmission latency, making it unsuitable for wider transmission needs.

[0004] Summary of the Invention

[0005] The present application provides a communication method, device, chip and module equipment that can reduce transmission delay and thus meet more transmission needs.

[0006] In a first aspect, a communication method is provided, comprising: receiving configuration information from a network device, where the configuration information is used to determine a subband full duplex (SBFD) area within a period.

[0007] As can be seen, in the above embodiment, the terminal device can receive network configuration information, which can be used to determine the SBFD area within a period. In other words, the terminal device can obtain the time-frequency resources for uplink and / or downlink transmission. For example, a timeslot can be used for both uplink transmission and downlink reception. This allows the terminal device to perform both uplink transmission and downlink reception in that timeslot, thereby reducing transmission latency and meeting more transmission requirements.

[0008] Optionally, in combination with the first aspect, the configuration information is used to determine the SBFD area within the cycle, including: the configuration information is used to indicate the first non-SBFD area and the second non-SBFD area within the cycle; wherein the SBFD area is the area in the cycle other than the first non-SBFD area and the second non-SBFD area.

[0009] As can be seen, in the above embodiment, the network device can indicate the first and second non-SBFD areas within a period to the terminal device, so that the terminal device can determine the SBFD area based on the first and second non-SBFD areas. In other words, even if the SBFD area is not explicitly indicated, the terminal device can deduce the SBFD area based on the first and second non-SBFD areas, providing greater flexibility.

[0010] Optionally, in combination with the first aspect, the configuration information is used to indicate the first non-SBFD area within the cycle, including: the configuration information is used to indicate a first number and a second number; the first number is the number of consecutive first non-SBFD time units starting from the start position of the cycle, and the second number is the number of consecutive non-SBFD time subunits or consecutive non-SBFD time subunit groups included in adjacent time units located after the consecutive first non-SBFD time units in the cycle; the first non-SBFD area is determined based on the first number and the second number; or, the configuration information is used to indicate a third number; the third number is the number of consecutive non-SBFD time subunits or consecutive non-SBFD time subunit groups starting from the start position of the cycle; the first non-SBFD area is determined based on the third number.

[0011] It can be seen that in the above embodiment, the network device can indicate a number, such as the first number and the second number, or the third number, so that the terminal device can determine the first non-SBFD area. In this way, signaling overhead can be saved.

[0012] Optionally, in combination with the first aspect, the configuration information is used to indicate the second non-SBFD area within the cycle, including: the configuration information is used to indicate a fourth number and a fifth number; the fourth number is the number of consecutive second non-SBFD time units starting from the end position of the cycle, and the fifth number is the number of consecutive non-SBFD time subunits or consecutive non-SBFD time subunit groups included in the adjacent time units located before the consecutive second non-SBFD time units in the cycle; the second non-SBFD area is determined based on the fourth number and the fifth number; or, the configuration information is used to indicate a sixth number; the sixth number is the number of consecutive non-SBFD time subunits or consecutive non-SBFD time subunit groups starting from the end position of the cycle; the second non-SBFD area is determined based on the sixth number.

[0013] It can be seen that in the above embodiment, the network device can indicate a number, such as the fourth number and the fifth number, or the sixth number, so that the terminal device can determine the second non-SBFD area. In this way, signaling overhead can be saved.

[0014] Optionally, in combination with the first aspect, the configuration information is used to determine the SBFD area within the cycle, including: the configuration information is used to indicate a seventh number and an eighth number; the seventh number is the number of continuous SBFD time units within the cycle, and the eighth number is the number of continuous SBFD time sub-units or continuous SBFD time sub-unit groups included in adjacent time units located after the continuous SBFD time unit within the cycle; the SBFD area is determined based on the seventh number and the eighth number; or, the configuration information is used to indicate a ninth number; the ninth number is the number of continuous SBFD time sub-units or continuous SBFD time sub-unit groups within the cycle; the SBFD area is determined based on the ninth number.

[0015] It can be seen that in the above embodiment, the network device can indicate numbers, such as the seventh number and the eighth number, or the ninth number, etc., so that the terminal device can determine the SBFD area. In this way, signaling overhead can be saved.

[0016] Optionally, in combination with the first aspect, the configuration information is also used to indicate a tenth number, which is the number of non-SBFD time sub-units or non-SBFD time sub-unit groups included in the adjacent time units located after the first consecutive non-SBFD time units in the cycle, and the first consecutive non-SBFD time units start at the start position of the cycle. The eleventh number is determined based on the tenth number, and the eleventh number is the number of consecutive SBFD time sub-units or consecutive SBFD time sub-unit groups included in the adjacent time units located before the consecutive SBFD time units in the cycle; or, the configuration information is also used to indicate the eleventh number; wherein, the SBFD area is determined based on the seventh number and the eighth number, including: the SBFD area is determined based on the seventh number, the eighth number and the eleventh number.

[0017] As can be seen, in the above embodiment, the network device can also indicate the tenth number so that the terminal device can determine the eleventh number, thereby indirectly determining the eleventh number based on the tenth number, which provides greater flexibility. Alternatively, the network device can also indicate the eleventh number, allowing the terminal device to directly obtain the number of consecutive SBFD time subunits or consecutive SBFD time subunit groups included in the adjacent time unit preceding the consecutive SBFD time unit within the cycle, thereby reducing calculation time within the terminal device. In addition, because the terminal device can determine the SBFD area based on the seventh, eighth, and eleventh numbers, signaling overhead can be reduced and the determined SBFD area can be more accurately determined.

[0018] Optionally, in combination with the first aspect, the configuration information is used to determine the SBFD area within the cycle, including: the configuration information is used to indicate the position, time length, twelfth number and thirteenth number of the starting time unit corresponding to the SBFD area within the cycle; the twelfth number is the number of consecutive SBFD time sub-units or consecutive SBFD time sub-unit groups included in the starting time unit, and the thirteenth number is the number of consecutive SBFD time sub-units or consecutive SBFD time sub-unit groups included in the last time unit in the area determined based on the position and time length of the starting time unit corresponding to the SBFD area; the SBFD area is determined based on the position, time length, twelfth number and thirteenth number of the starting time unit corresponding to the SBFD area; or, the configuration information is used to indicate the position, time length and fourteenth number of the starting time unit corresponding to the SBFD area within the cycle; the fourteenth number is the number of consecutive SBFD time sub-units or consecutive SBFD time sub-unit groups in the area determined based on the position and time length of the starting time unit corresponding to the SBFD area; the SBFD area is determined based on the position, time length and fourteenth number of the starting time unit corresponding to the SBFD area.

[0019] As can be seen, in the above embodiment, the network device can indicate the location of the starting time unit, the time length, and the relevant number (such as the twelfth and thirteenth numbers, or the fourteenth number, etc.) so that the terminal device can determine the SBFD area. This can save signaling overhead and make the determination of the SBFD area more accurate.

[0020] Optionally, in combination with the first aspect, the configuration information is used to determine the SBFD area within the period, including: the configuration information is used to indicate the type of time sub-unit included in the first time unit within the period; when the type of all time sub-units included in the first time unit is SBFD, the first time unit is located in the SBFD area; and / or, when the type of at least one time sub-unit included in the first time unit is SBFD, at least one time sub-unit is located in the SBFD area.

[0021] It can be seen that in the above embodiment, the network device can indicate the type of time subunit included in the first time unit within the cycle, so that the terminal device can know the area where the time subunit is located, such as the SBFD area. In this way, the terminal device can know the time-frequency resources for uplink and / or downlink transmission. For example, a time slot can be used for both uplink transmission and downlink reception. This allows the terminal device to perform both uplink transmission and downlink reception in the time slot, thereby reducing transmission delay and meeting more transmission requirements.

[0062] In some possible implementations, the terminal device can be deployed on land, including indoors or outdoors, handheld, wearable or vehicle-mounted; can be deployed on the water surface (such as ships, etc.); can be deployed in the air (such as airplanes, balloons and satellites, etc.).

[0063] In some possible implementations, the terminal device may include a device with wireless communication functionality, such as a chip system, a chip, or a chip module. For example, the chip system may include a chip and may also include other discrete devices.

[0064] In some possible implementations, the terminal device described in the embodiments of the present application may be a chip, a chip module, a device, a unit, etc., without specific limitation.

[0065] 2. Network Equipment

[0066] A network device may be a device with transceiver functions that can communicate with terminal devices.

[0067] In some possible implementations, the network device may be responsible for radio resource management (RRM), quality of service (QoS) management, data compression and encryption, data transmission and reception, etc. on the air interface side.

[0068] In some possible implementations, the network device may include a base station (BS) in a communication system or a device deployed in a radio access network (RAN) for providing wireless communication functions, that is, the network device may include a device in the RAN.

[0069] For example, the devices in the RAN may include an evolved node B (eNB or eNodeB) in an LTE communication system, a next generation evolved node B (ng-eNB) in an NR communication system, a next generation node B (gNB) in an NR communication system, a master node (MN) in a dual-connection architecture, a second node or secondary node (SN) in a dual-connection architecture, etc., without specific limitation.

For example, the network device includes a centralized unit (CU) and a distributed unit (DU), such as a gNB-CU and a gNB-DU. Furthermore, in other embodiments of the present application, the network device may also include an active antenna unit (AAU). The CU implements part of the functions of the network device, and the DU implements another part of the functions of the network device. For example, the CU is responsible for processing non-real-time protocols and services, and implements the functions of the radio resource control (RRC) layer, the service data adaptation protocol (SDAP) layer, and the packet data convergence protocol (PDCP) layer. The DU is responsible for processing physical layer protocols and real-time services, and implements the functions of the radio link control (RLC) layer, the medium access control (MAC) layer, and the physical (PHY) layer. In addition, the AAU can implement some physical layer processing functions, RF processing, and related functions of the active antenna. Because RRC layer information ultimately becomes PHY layer information, or is converted from PHY layer information, in this network deployment, high-layer signaling (such as RRC signaling) can be considered to be generated by the CU and sent by the DU, or sent jointly by the DU and AAU. It is understood that network devices may include at least one of the CU, DU, and AAU. Furthermore, the CU may be classified as a RAN device, or as a core network device, without specific limitation.

Among them, multi-site coherent cooperative transmission can be joint coherent transmission of multiple sites, or different data belonging to the same physical downlink shared channel (PDSCH) are sent from different sites to the terminal device, or multiple sites are virtualized into one site for transmission. Names with the same meaning specified in other standards also apply to this application, that is, this application does not limit the names of these parameters. The sites in multi-site coherent cooperative transmission can be remote radio heads (RRHs), transmission and reception points (TRPs), network devices, etc., and there is no specific limitation on this.

For example, the satellite may be a low earth orbit (LEO) satellite, a medium earth orbit (MEO) satellite, a geostationary earth orbit (GEO) satellite, a high elliptical orbit (HEO) satellite, etc. Alternatively, the network device may be a base station located on land, water, or the like.

[0079] In some possible implementations, a network device may provide services for a cell, and a terminal device in the cell may communicate with the network device using transmission resources (e.g., spectrum resources).

Of course, with the evolution of communication technology, the number of symbols included in a time slot may also be other values, and this application does not limit it.

[0085] It should be noted that the symbols involved in this application may be orthogonal frequency-division multiplexing (OFDM) symbols.

[0097] 1. Configuration information is used to indicate a first number and a second number; the first number is the number of consecutive first non-SBFD time units starting at the start position of the cycle, and the second number is the number of consecutive non-SBFD time subunits or consecutive non-SBFD time subunit groups included in the adjacent time units following the consecutive first non-SBFD time units within the cycle; the first non-SBFD region is determined based on the first and second numbers. A non-SBFD time unit (such as a first non-SBFD time unit) mentioned in this application refers to a time unit used for uplink or downlink transmission. A non-SBFD time subunit mentioned in this application refers to a time subunit used for uplink or downlink transmission. A non-SBFD time subunit group mentioned in this application may include at least one non-SBFD time subunit. For example, in 4-1 of Figure 4 , it is assumed that the first number is the number of consecutive non-SBFD time slots starting at the start position of the cycle, and the second number is the number of consecutive non-SBFD symbols included in the adjacent time slots following the consecutive non-SBFD time slots within the cycle.

The configuration information indicates a third number; the third number is the number of consecutive non-SBFD time subunits or groups of consecutive non-SBFD time subunits starting at the start of the cycle; the first non-SBFD region is determined based on the third number. For example, in 4-2 of Figure 4 , it is assumed that the third number is the number of consecutive non-SBFD symbols starting at the start of the cycle. Thus, the first non-SBFD region can be determined based on the third number. Optionally, the consecutive non-SBFD time subunits mentioned herein may be located within at least one non-SBFD time unit. Alternatively, the consecutive non-SBFD time subunit groups mentioned herein may be located within at least one non-SBFD time unit.

Optionally, the consecutive non-SBFD time subunits mentioned herein may be located within at least one non-SBFD time unit. Alternatively, the consecutive non-SBFD time subunit groups mentioned herein may be located within at least one non-SBFD time unit.

The SBFD time subunits mentioned in this application refer to time subunits used for uplink and downlink transmission. The SBFD time subunit group mentioned in this application may include at least one SBFD time subunit. For example, in 6-1 of Figure 6 , it is assumed that the seventh number is the number of consecutive SBFD time slots within a cycle, and the eighth number is the number of consecutive SBFD symbols included in the adjacent time slots following the consecutive SBFD time slots within the cycle. In this way, the SBFD area can be determined based on the seventh and eighth numbers.

[0103] Optionally, when the configuration information is used to indicate the seventh number and the eighth number, the configuration information may also be used to indicate the tenth number or the eleventh number.

[0104] The tenth number is the number of non-SBFD time subunits or non-SBFD time subunit groups included in the adjacent time units following the first consecutive non-SBFD time unit within the cycle, where the first consecutive non-SBFD time unit starts at the beginning of the cycle. The eleventh number is the number of consecutive SBFD time subunits or consecutive SBFD time subunit groups included in the adjacent time units preceding the consecutive SBFD time unit within the cycle.

[0105] Optionally, if the configuration information also indicates the tenth number, the eleventh number can be determined based on the tenth number. For example, if the adjacent time unit following the first consecutive non-SBFD time unit is a time slot, and the number of non-SBFD symbols included in the time slot is 4, then the tenth number is 4. If the total number of symbols included in the time slot is 14, then the eleventh number is 10, that is, 14-4=10.

[0106] Optionally, the SBFD area is determined based on the seventh number and the eighth number, including: the SBFD area is determined based on the seventh number, the eighth number and the eleventh number.

[0107] 3.

For example, assume that the ninth number is the number of consecutive SBFD symbols within a cycle. Thus, the SBFD region can be determined based on the ninth number. Optionally, the consecutive SBFD time subunits mentioned herein may be within at least one SBFD time unit. Alternatively, the consecutive SBFD time subunit groups mentioned herein may be within at least one SBFD time unit.

[0108] 4. The configuration information is used to indicate the position, time length, twelfth number, and thirteenth number of the starting time unit corresponding to the SBFD region within the period; the twelfth number is the number of consecutive SBFD time subunits or consecutive SBFD time subunit groups included in the starting time unit, and the thirteenth number is the number of consecutive SBFD time subunits or consecutive SBFD time subunit groups included in the last time unit in the region determined based on the position and time length of the starting time unit corresponding to the SBFD region; the SBFD region is determined based on the position, time length, twelfth number, and thirteenth number of the starting time unit corresponding to the SBFD region. For example, in 7-1 of Figure 7, it is assumed that the region determined based on the position and time length of the starting time slot corresponding to the SBFD region includes three time slots, namely, the starting time slot, the middle time slot, and the last time slot from left to right. The twelfth number is the number of consecutive SBFD symbols included in the starting time slot, such as 8. The thirteenth number is the number of consecutive SBFD symbols included in the last time slot, such as 6. In this way, the SBFD region may include 8 consecutive SBFD symbols in the starting time slot, the middle time slot, and 6 consecutive SBFD symbols in the last time slot.

[0109] 5. The configuration information is used to indicate the position, time length, and fourteenth number of the starting time unit corresponding to the SBFD region within the period; the fourteenth number is the number of consecutive SBFD time subunits or consecutive SBFD time subunit groups within the region determined based on the position and time length of the starting time unit corresponding to the SBFD region; the SBFD region is determined based on the position, time length, and fourteenth number of the starting time unit corresponding to the SBFD region. For example, in 7-2 of Figure 7 , it is assumed that the region determined based on the position and time length of the starting time slot corresponding to the SBFD region includes three time slots, which are the starting time slot, the middle time slot, and the last time slot from left to right. The fourteenth number is the number of consecutive SBFD symbols included in the three time slots, such as 28. In this way, the SBFD region can include 28 consecutive SBFD symbols in the three time slots.

[0110] 6. The configuration information is used to indicate the type of time subunits included in the first time unit within the period; when all time subunits included in the first time unit are of SBFD type, the first time unit is located in the SBFD area; and / or, when at least one time subunit included in the first time unit is of SBFD type, the at least one time subunit is located in the SBFD area. Optionally, at least one time subunit is located at the start or end of the SBFD area. As shown in Figure 3, there are a total of 5 time slots from left to right. The type of at least one symbol included in the second time slot from left to right is SBFD, therefore, the at least one symbol included in the second time slot is located in the SBFD area. The at least one symbol included in the second time slot is located at the start position of the SBFD area. The type of at least one symbol included in the fourth time slot from left to right is SBFD, therefore, the at least one symbol included in the fourth time slot is located in the SBFD area. The at least one symbol included in the fourth time slot is located at the end position of the SBFD area.

[0111] Optionally, the number of first time units may be one or more. That is, the configuration information may be used to indicate the type of time subunits included in each first time unit within a period. For example, if all time subunits included in the first time unit are of non-SBFD type, the first time unit is located in the first non-SBFD area or the second non-SBFD area. The non-SBFD mentioned here may refer to uplink or downlink. If all symbols included in a time slot are of uplink type, the time slot is located in the first non-SBFD area.

[0112] It should be noted that the above-mentioned methods 1 to 6 are merely examples of some solutions and can be combined. This solution does not limit this. In addition, any one of the first non-SBFD area and the second non-SBFD area can be indicated by configuration information. For details, please refer to the description of the above-mentioned method 1. Alternatively, the first non-SBFD area can be determined by the SBFD area and / or the second non-SBFD area. Alternatively, the second non-SBFD area can be determined by the SBFD area and / or the first non-SBFD area, etc., which are not limited here.

[0113] Alternatively, the second non-SBFD region can be determined by the SBFD region or the first non-SBFD region

[0114] Optionally, for the second method described above, if the configuration information also indicates a tenth number (the tenth number is the number of non-SBFD time subunits or non-SBFD time subunit groups included in adjacent time units following the first consecutive non-SBFD time units within the period), the period may also include a guard interval. Optionally, the guard interval is the area within the period excluding the SBFD area, the first non-SBFD area, and the second non-SBFD area. As shown in Figure 8, the guard interval may be located after the first non-SBFD area and before the SBFD area.

[0115] Optionally, the configuration information mentioned in any of the above methods 1 to 5 can be carried in cell-level signaling, such as system information blocks 1 (SIB1). For example, the configuration information can be carried in the ServingCellConfigCommon signaling of SIB1, signaling with similar definitions or functions, signaling of extended fields, or signaling of extended fields of ServingCellConfigCommon, etc. For example, the ServingCellConfigCommon signaling can include SBFD-ConfigurationCommon-r19 signaling. The configuration information can be carried in the SBFD-ConfigurationCommon-r19 signaling.

[0116] Optionally, the configuration information mentioned in the above method six can be carried in UE dedicated signaling, such as radio resource control (RRC) signaling, media access control layer control element (MAC CE) or downlink control information (DCI).

[0117] As can be seen, in the above embodiment, the terminal device can receive network configuration information, which can be used to determine the SBFD area within a period. In other words, the terminal device can obtain the time-frequency resources for uplink and / or downlink transmission. For example, a timeslot can be used for both uplink transmission and downlink reception. This allows the terminal device to perform both uplink transmission and downlink reception in that timeslot, thereby reducing transmission latency and meeting more transmission requirements.
