Description

Technical Field

[0001] The present invention relates to the field of wireless communication technologies, and in particular, to a communication method and device, and a computer-readable storage medium. Background Art

[0002] In the existing Time Division Duplexing (TDD) system, the transmission directions of all frequency-domain resources of a TDD carrier need to be the same at the same moment, and the uplink and downlink time slot ratios of different frequency-domain resources cannot be flexibly configured. With the diversification of data services, different services have different requirements for uplink and downlink transmissions, and a single uplink and downlink time slot ratio cannot meet the requirements of different services.

[0003] In the prior art, a sub-band full-duplex transmission scheme is proposed. A network device (such as a base station, etc.) divides the same TDD carrier into different sub-bands in the frequency domain, and simultaneously performs uplink reception and downlink transmission on different sub-bands respectively. Summary of the Invention

[0004] One of the purposes of the embodiments of the present invention is to provide a communication method, in which a terminal device can determine symbols of sub-band full duplex within a time slot.

[0005] In a first aspect, the present invention provides a communication method, including: obtaining first configuration information, where the first configuration information configures first symbols of sub-band full duplex, and the first symbols include at least one downlink symbol and / or flexible symbols.

[0006] The network device configures first symbols of sub-band full duplex through the first configuration information. Based on the first configuration information, the terminal device can determine the first symbols of sub-band full duplex, perform uplink data transmission on the uplink sub-bands of the frequency-domain resources of the first symbols, and perform downlink data reception on the downlink sub-bands of the frequency-domain resources of the first symbols.

[0007] Optionally, the first configuration information is sent via cell-level high-layer signaling.

[0008] Optionally, the terminal device may further obtain second configuration information, where the second configuration information indicates that the transmission direction of the downlink symbol is downlink transmission; and / or, the second configuration information indicates that the transmission direction of the flexible symbol is downlink transmission or flexible transmission.

[0009] The network device may also send second configuration information to the terminal device. Based on the second configuration information, the terminal device may determine the transmission direction of the first symbol. When the first symbol is a downlink symbol, the second configuration information indicates that the transmission direction of the first symbol is downlink transmission; when the first symbol is a flexible symbol, the second configuration information indicates that the transmission direction of the first symbol is downlink transmission or flexible transmission. After configuring the first symbol through the first configuration information, the indication of the transmission direction of the first symbol by the second configuration information is restricted. Or rather, the indication of the transmission direction of the first symbol by the second configuration information is limited by the configuration of the first configuration information.

[0010] Optionally, the second configuration information may be carried by terminal device-level high-layer signaling or by dynamic signaling.

[0011] Optionally, the first symbol includes a flexible symbol, and the frequency-domain resources of the flexible symbol include an uplink sub-band and a downlink sub-band. When the second configuration information is carried by dynamic signaling, the uplink sub-band of the first symbol is used to transmit dynamically scheduled uplink data, and the downlink sub-band of the first symbol transmits dynamically scheduled downlink data.

[0012] Optionally, when the terminal device detects a conflict between the semi-statically configured uplink data transmission and the semi-statically configured downlink data reception within the first symbol, it may stop the uplink data transmission or stop the downlink data reception based on the data priority.

[0013] Optionally, the priority of the configured grant physical uplink shared channel CG-PUSCH may be higher than the priority of the channel state information reference signal CSI-RS; or, the priority of the physical downlink control channel PDCCH may be higher than the priority of the physical uplink control channel PUCCH; or, the priority of the PDCCH may be higher than the priority of the CG-PUSCH; or, the priority of the semi-persistent scheduling physical downlink shared channel SPS PDSCH may be higher than the priority of the uplink reference signal SRS; or, the priority of the physical random access channel PRACH may be higher than the priority of the SPS PDSCH; or, the priority of the PRACH may be higher than the priority of the PDCCH; or, the priority of the PRACH may be higher than the priority of the CSI-RS; or, the priority of the signal / channel with a front-starting symbol in the time domain is higher than the priority of the signal / channel with a later-starting symbol.

[0014] In the first symbol, if there is a conflict in the time domain between the semi-statically configured uplink data transmission and the semi-statically configured downlink data, the terminal device may determine whether to perform uplink data transmission or downlink data reception based on the data priority, providing a solution for the data conflict scenario.

[0015] Second aspect, the present invention provides another communication method, including: sending first configuration information, where the first configuration information configures a first symbol of sub-band full duplex, and the first symbol includes at least one downlink symbol and / or flexible symbol.

[0016] Optionally, the network device may send the first configuration information by using cell-level high-layer signaling.

[0017] Optionally, the network device may further send second configuration information to the terminal device, where the second configuration information indicates that the transmission direction of the downlink symbol is downlink transmission; and / or, the second configuration information indicates that the transmission direction of the flexible symbol is downlink transmission or flexible transmission.

[0018] Optionally, the network device may send the second configuration information by using terminal device-level high-layer signaling; or, carry the second configuration information by using dynamic signaling.

[0019] Third aspect, the present invention provides a communication device, including: an acquisition unit, configured to acquire first configuration information, where the first configuration information configures a first symbol of sub-band full duplex, and the first symbol includes at least one downlink symbol and / or flexible symbol.

[0020] Fourth aspect, the present invention provides another communication device, including: a sending unit, configured to send first configuration information, where the first configuration information configures a first symbol of sub-band full duplex, and the first symbol includes at least one downlink symbol and / or flexible symbol.

[0021] Fifth aspect, the present invention further provides a computer-readable storage medium, where the computer-readable storage medium is a non-volatile storage medium or a non-transitory storage medium, and a computer program is stored thereon. When the computer program is run by a processor, it executes the steps of any one of the above-mentioned communication methods.

[0022] Sixth aspect, the present invention further provides another communication device, including a memory and a processor. A computer program that can run on the processor is stored on the memory.

Exemplarily, the chip system can include a chip and can also include other discrete devices.

[0033] In some embodiments, the network device can also communicate with an Internet Protocol (IP) network, such as the Internet, a private IP network, or other data networks, etc.

[0034] The embodiments of the present invention provide a communication method, which will be described in detail through specific steps with reference to Figure 1 , as follows.

[0035] In an embodiment of the present invention, the communication method provided in step 101 below may be executed by a chip with data processing capabilities (such as a baseband chip) in a terminal device, or may be executed by a chip module with data processing capabilities in the terminal device, or may also be executed by the terminal device. In the following embodiments, the case where the terminal device executes is taken as an example for description.

[0036] Step 101: Obtain first configuration information, where the first configuration information configures a first symbol for sub-band full duplex.

[0037] In an embodiment of the present invention, a network device may configure a first symbol for sub-band full duplex for a terminal device. The network device may send the first configuration information to the terminal device, and indicate, through the first configuration information, the first symbol in one or more time slots to the terminal device. The first symbol may include at least one downlink symbol and / or flexible symbol. The network device may determine, according to specific application requirements, the time slots configured with the first symbol, and the number of first symbols configured in the corresponding time slots.

[0038] Thus, through the first configuration information, the network device can indicate the time domain position of sub-band full duplex, and the time domain position of sub-band full duplex is the time domain position of the first symbol.

[0039] In a specific implementation, the network device may also configure the frequency domain position of sub-band full duplex for the terminal device. Specifically, the network device may configure the frequency domain position of sub-band full duplex based on different subcarrier intervals. The frequency domain position of sub-band full duplex may include an uplink sub-band and a downlink sub-band. The uplink sub-band may be used for uplink data transmission, and the downlink sub-band may be used for downlink data reception.

[0040] In an embodiment of the present invention, the network device may carry the first configuration information through cell-level high-layer signaling. The terminal device may receive the cell-level high-layer signaling and obtain the first configuration information therefrom. The terminal device may determine the first symbol of sub-band full duplex based on the first configuration information.

[0041] In some embodiments, the cell-level high-layer signaling may include a System Information Block (SIB), or radio resource control (RRC) signaling, or a Medium Access Control Control Element (MAC CE), etc.

[0042] Specifically, when the cell high-layer signaling includes an SIB, the first configuration information may be carried through the TDD-UL-DL-ConfigCommon parameter in the SIB.

[0043] In a specific implementation, the first symbol may include at least one downlink symbol and / or a flexible symbol. Among them, the downlink symbol may refer to a symbol configured by a network device for downlink data transmission; the flexible symbol may refer to a symbol configured by a network device without a determined transmission direction, and the network device may specify the transmission direction of the flexible symbol as downlink or uplink through control signaling.

[0044] It can be known from specific applications that all symbols within a time slot may all be uplink symbols, or all be downlink symbols, or all be flexible symbols, or include at least two of uplink symbols, downlink symbols, and flexible symbols.

[0045] Referring to Figures 2 to 6 , several schematic diagrams of symbol distributions within existing time slots are given. Figure 2 In [reference], a time slot includes 14 symbols, and all 14 symbols are downlink symbols for downlink data reception. Figure 3 In [reference], a time slot includes 14 symbols, and all 14 symbols are uplink symbols for uplink data transmission. Figure 4 In [reference], a time slot includes 14 symbols, and all 14 symbols are flexible symbols. Figure 5 In [reference], a time slot includes 14 symbols, where symbols 0 to 4 are downlink symbols, symbols 5 to 6 are flexible symbols, and symbols 7 to 13 are uplink symbols. Figure 6 In [reference], symbols 0 to 2 and symbols 7 to 9 are uplink symbols, symbols 3 to 5 and symbols 10 to 11 are flexible symbols, and symbols 6 and symbols 12 to 13 are downlink symbols.

[0046] Thus, the network device may, through the first configuration information, indicate to the terminal device the first symbol of subband full duplex within the time slot. The terminal device may, based on the first configuration information, perform uplink data transmission in the uplink subband corresponding to the first symbol and perform downlink data reception in the downlink subband corresponding to the first symbol.

[0047] Referring to Figure 7 , a schematic diagram of an application scenario in an embodiment of the present invention is given.

[0048] Figure 7 In [reference], all symbols in time slot slot n are downlink symbols. All symbols in time slot slot n + 1 may achieve subband full duplex (that is, all symbols in time slot slot n + 1 are first symbols), and the uplink subbands for uplink data transmission are as shown by U in Figure 7 , and the downlink subbands for downlink data reception are as shown by D in Figure 7 .

[0049] All symbols in time slot slot n+2 can also achieve sub-band full duplex (i.e., all symbols in time slot slot n+2 are first symbols), and the uplink sub-band for uplink data transmission is as shown in Figure 7 U in Figure 7 shown, and the downlink sub-band for downlink data reception is as shown in

[0050] D in

[0051] Symbols 0 to 9 in time slot slot n+3 can all achieve sub-band full duplex, symbol 10 is a flexible symbol, and symbols 11 to 13 are used for uplink data transmission. All symbols in time slot slot n+4 are used for uplink data transmission.

[0051] In the embodiments of the present invention, after the network device configures sub-band full duplex on the first symbol through the first configuration information, the network device can also indicate the transmission direction of the first symbol through the second configuration information.

[0052] In a specific implementation, when the network device indicates the transmission direction of the first symbol through the second configuration information, the transmission direction of the first symbol is restricted.

[0053] In a specific implementation, the second configuration information can be carried by the terminal device-level high-layer signaling. The network device can indicate the corresponding transmission direction of the first symbol through the terminal device-level high-layer signaling.

[0054] In some embodiments, the terminal device-level high-layer signaling can be the TDD-UL-DL-ConfigDedicated signaling.

[0055] Specifically, if the first symbol includes a downlink symbol, the network device can indicate, through the second configuration information, that the transmission direction of the downlink symbol is downlink transmission.

[0056] That is to say, if the first symbol is a downlink symbol, when the network device indicates the transmission direction of the first symbol through the second configuration information, it still indicates that the transmission direction of the first symbol is downlink data reception.

[0057] If the first symbol includes a flexible symbol, the network device can indicate, through the second configuration information, that the transmission direction of the flexible symbol is downlink transmission or flexible transmission.

[0058] That is to say, if the first symbol is a flexible symbol, when the network device indicates the transmission direction of the first symbol through the second configuration information, it can indicate that the transmission direction of the first symbol is downlink data reception, or flexible transmission.

[0059] In the embodiments of the present invention, the second configuration information can also be carried by dynamic signaling to configure the transmission direction of the first symbol through the dynamic signaling.

[0060] In some embodiments, the dynamic signaling may include Slot Format Information (SFI), and the number of uplink symbols, downlink symbols, and flexible symbols in a time slot is indicated by the SFI signaling.

[0061] After the network device configures the first symbol of sub-band full duplex through the first indication information, if the first symbol is a downlink symbol, the SFI signaling may indicate that the transmission direction of the first symbol is downlink data reception; if the first symbol is a flexible symbol, the SFI signaling may indicate that the transmission direction of the first symbol is downlink data reception, or the transmission direction of the first symbol is flexible reception (that is, indicate that the first symbol is a flexible symbol).

[0062] Specifically, if the SFI signaling indicates that the first symbol is a downlink symbol, the terminal device may perform uplink data transmission on the uplink sub-band corresponding to the first symbol and perform downlink data reception on the downlink sub-band corresponding to the first symbol.

[0063] If the SFI signaling indicates that the first symbol is a flexible symbol, the terminal device may send dynamically scheduled uplink data on the uplink sub-band corresponding to the first symbol and send scheduled downlink data on the downlink sub-band corresponding to the first symbol.

[0064] In some embodiments, if the SFI signaling indicates that the first symbol is a flexible symbol, the terminal device does not send non-dynamically scheduled uplink data (such as uplink CG-PUSCH configured by high-layer signaling, periodic measurement reference signals, etc.) on the uplink sub-band corresponding to the first symbol; the terminal device does not send non-dynamically scheduled downlink data (such as periodic CSI-RS, SPS PDSCH, etc.) on the downlink sub-band corresponding to the first symbol.

[0065] In the embodiments of the present invention, within the first symbol, there may be a conflict between semi-statically configured uplink data transmission and semi-statically configured downlink data reception. When the terminal device detects the above conflict, it may stop uplink data transmission or downlink data reception based on the data priority.

[0066] In specific implementation, the data priority may be determined based on the type of semi-static signal / channel.

[0067] In some embodiments, the priority of the Configured Grant Physical Uplink Shared Channel (CG-PUSCH) is higher than that of the Channel State Information Reference Signal (CSI-RS); and / or, the priority of the Physical Downlink Control Channel (PDCCH) is higher than that of the Physical Uplink Control Channel (PUCCH); and / or, the priority of the PDCCH is higher than that of the CG-PUSCH; and / or, the priority of the Physical Random Access Channel (PRACH) is higher than that of the semi-persistent scheduling (SPS) PDSCH, PDCCH, and CSI-RS; or, in the same time slot, the priority of the signal / channel with an earlier starting symbol in the time domain is higher than that of the signal / channel with a later starting symbol.

[0068] Referring to Figure 8 , a schematic diagram of resolving resource conflicts in a semi-static configuration according to an embodiment of the present invention is given. Figure 8 In [the figure], in slot n+1, within the first symbol of the subband full duplex, there is a semi-statically configured CG-PUSCH and a semi-statically configured CSI-RS. From the above data priorities, it can be determined that the priority of the semi-statically configured CG-PUSCH is higher than that of the CSI-RS. Therefore, in the frequency domain resources of the first symbol of slot n+1, an uplink transmission of the CG-PUSCH is performed, and the downlink transmission of the CSI-RS is discarded.

[0069] Continuing to refer to Figure 8 , in slot n+2, within the first symbol of the subband full duplex, there is a semi-statically configured PDCCH and a semi-statically configured CG-PUSCH. From the above data priorities, it can be determined that the priority of the semi-statically configured PDCCH is higher than that of the CG-PUSCH. Therefore, in the frequency domain resources of the first symbol of slot n+2, a downlink transmission of the PDCCH is performed, and the uplink transmission of the CG-PUSCH is discarded.

[0070] Continuing to refer to Figure 8, in slot n+3, within the first symbol of subband full duplex, there is a semi-statically configured SPS PDSCH and a semi-statically configured CG-PUSCH. In the time domain, the starting symbol of the SPS PDSCH is earlier than that of the CG-PUSCH, so the priority of the SPS PDSCH is higher than that of the CG-PUSCH. On the frequency domain resources of the first symbol in slot n+3, downlink transmission of the SPS PDSCH is performed, and the uplink transmission of the CG-PUSCH is discarded.
