Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a communication method and device. Background Art

[0002] Time division duplexing (TDD) refers to a technology in which all frequency domain resources in a time unit can only be used for uplink or downlink transmission. Simultaneous full duplexing refers to a technology in which both uplink and downlink transmission can be carried out in a time-frequency unit.

[0003] In the TDD transmission system of the existing new radio (NR) system, if both uplink transmission and downlink transmission exist on a flexible symbol, the scheduling types in the two directions are used to determine which direction to transmit in.

[0004] However, in a simultaneous, co-frequency, full-duplex transmission system, if both uplink and downlink transmissions are performed on the same time-frequency resource, the frequency of simultaneous uplink and downlink transmissions increases significantly, causing the transmitted signals to self-interfere with the received signals. For example, for network equipment, transmitting downlink signals on the same time-frequency resource will self-interfere with the received uplink signal. For another example, for terminal devices, transmitting uplink signals on the same time-frequency resource will self-interfere with the received downlink signal. Therefore, how to reduce the self-interference of simultaneous, co-frequency, full-duplex transmission for important channels / signals remains to be studied. Summary of the Invention

[0129] 1. Simultaneous and same-frequency full-duplex technology.

[0130] Simultaneous, same-frequency full-duplex technology allows network devices and terminal devices to simultaneously transmit uplink and downlink signals on the same time-frequency resources. Network devices can send downlink signals and receive uplink signals on the same time-frequency resources. Terminal devices can also send uplink signals and receive downlink signals on the same time-frequency resources.

[0131] In addition, in the embodiments of the present application, for network devices, uplink transmission refers to uplink reception, and downlink transmission refers to downlink transmission; for terminal devices, uplink transmission refers to uplink transmission, and downlink transmission refers to downlink reception.

[0132] For example, Figure 2 A schematic diagram of a resource. Figure 2 Each square in the figure represents a time-frequency resource, and "U / D" means that the time-frequency resource can be used for both uplink and downlink transmission.

[0133] 2. Transmission principles.

[0134] In time division duplexing (TDD) transmission systems and frequency division duplexing (FDD) transmission systems that do not support full duplex, when the time-frequency resources occupied by uplink transmission overlap with those occupied by downlink transmission, dynamically scheduled transmission takes precedence over semi-persistently scheduled transmission. When the time-frequency resources occupied by dynamically scheduled transmission overlap with those occupied by semi-persistently scheduled transmission in the opposite direction of dynamically scheduled transmission, the semi-persistently scheduled transmission can be canceled.

[0135] For example, Figure 3a is a scheduling diagram. Figure 3a As shown, downlink control information (DCI) dynamically schedules the physical downlink shared channel (PDSCH), while the physical uplink shared channel (PUSCH) belongs to the semi-static scheduling transmission. Figure 3aAs shown, after the terminal device decodes the received DCI, it is determined that the time-frequency resources occupied by the PDSCH scheduled by the DCI overlap with the time-frequency resources occupied by the semi-static PUSCH. Since the priority of the dynamic scheduling transmission is higher than the priority of the semi-static scheduling transmission, the terminal device prioritizes the reception of the PDSCH and cancels the transmission of the semi-static PUSCH. In addition, the preparation time for the terminal device to cancel the transmission of the semi-static PUSCH is the time window T. If the terminal device starts to send the semi-static PUSCH after the time window T, the transmission of the semi-static PUSCH is canceled; if the terminal device sends the semi-static PUSCH before the time window T, the semi-static PUSCH may not be canceled and may be sent.

[0136] For example, Figure 3b This is another scheduling diagram. Figure 3b As shown, DCI dynamically schedules PDSCH, and the channel sounding reference signal (SRS) belongs to the semi-statically scheduled transmission. When the terminal device decodes the received DCI and determines that the time-frequency resources occupied by the PDSCH scheduled by the DCI overlap with the time-frequency resources occupied by the SRS, the priority of the dynamically scheduled transmission is higher than the priority of the semi-statically scheduled transmission. The terminal device then gives priority to ensuring the reception of PDSCH and cancels the transmission of the semi-static SRS. In addition, the preparation time for the terminal device to cancel the transmission of the semi-static SRS is time window T. If the terminal device sends a semi-static SRS before time window T, the transmission of the SRS before time window T can be guaranteed, and the transmission of the SRS after time window T can be canceled.

[0137] When the time-frequency resources occupied by the physical uplink control channel (PUCCH) / PUSCH / SRS / physical random access channel (PRACH) transmission overlap, the terminal device does not send PUCCH / PUSCH / PRACH, and the terminal device sends SRS on the time-frequency resources that do not overlap with the time-frequency resources occupied by other signals.

[0138] PUCCH is divided into five formats: 0-4. For format 3, the hybrid automatic repeat request (HARQ), scheduling request (SR), channel state information part 1 (CSI part 1), and channel state information part 2 (CSI part 2) determine their distance from the demodulation reference signal (DMRS) according to different priorities.

[0139] See also Figure 4 , Figure 4 This is a schematic diagram of a signal time domain structure. Specifically, Figure 4 This is a schematic diagram of the time domain structure of PUCCH corresponding to format 3. Figure 4 As shown in the figure, the priority of HARQ, SR, and CSI part 1 is higher than that of CSI part 2. That is, the priority relationship between HARQ, SR, and CSI part 1 and CSI part 2 is HARQ, SR, and CSI part 1 > CSI part 2. Therefore, the distance between HARQ, SR, and CSI part 1 and DMRS is closer than that between CSI part 2 and DMRS.

[0140] For format 4, the distance between HARQ, CSI part 1 and CSI part 2 and DMRS is determined by the priority relationship between HARQ, CSI part 1 and CSI part 2. Figure 5 and Figure 6 , Figure 5 and Figure 6 They are schematic diagrams of another signal time domain structure. Specifically, Figure 5 and Figure 6 This is a schematic diagram of the time domain structure of PUCCH corresponding to format 4. Figure 5 and Figure 6 In the example, the priority relationship among HARQ, CSI part1 and CSI part2 is HARQ>CSI part1>CSI part2. Therefore, HARQ is placed first, then CSI part1, and finally CSI part2. Figure 5As shown, DMRS is located in the third column, HARQ is placed in the fourth column, CSI part 1 is placed in the first and second columns, and CSI part 2 is placed in the second, fourth, and fifth columns. Figure 6 As shown, DMRS is located in the first column, HARQ is placed in the second column, CSI part 1 is placed in the third and fourth columns, and CSI part 2 is placed in the second, fourth, and fifth columns. It can be seen that when the position of DMRS is different, the position of CSI part 1 relative to DMRS is different.

[0141] Currently, terminal devices and network devices simultaneously perform uplink and downlink transmissions on the same time-frequency resources, which will cause self-interference to the signal transmission between the network devices and the terminal devices. Figure 7 is a scheduling diagram. Figure 7 As shown, the time when the network device sends the downlink signal overlaps with the time when the terminal device sends the uplink signal. As a result, the time when the terminal device receives the downlink signal overlaps with the time when the uplink signal is sent. As a result, the reception of the downlink signal is interfered with by the transmission of the uplink signal, which reduces the accuracy of the downlink signal reception. In addition, if the time when the network device sends the downlink signal overlaps with the time when it receives the uplink signal, the transmission of the downlink signal interferes with the reception of the uplink signal, which reduces the accuracy of the downlink and uplink signal reception.

[0142] It can be seen that when terminal devices and network devices perform uplink and downlink transmissions simultaneously on the same time-frequency resources, self-interference occurs, which will reduce the accuracy of signal reception.

[0143] Based on the above description, the embodiment of the present application proposes a communication method 100. Figure 8 is a schematic diagram of a communication method 100, which includes but is not limited to:

[0144] S101. When the first time-frequency resource occupied by the first uplink signal / channel overlaps with the second time-frequency resource occupied by the first downlink signal / channel, the terminal device sends the first uplink signal / channel on the third time-frequency resource, and cancels or partially cancels the reception of the first downlink signal / channel on the second time-frequency resource according to the priority of the first uplink signal / channel and the priority of the first downlink signal / channel; or, when the first time-frequency resource occupied by the first uplink signal / channel overlaps with the second time-frequency resource occupied by the first downlink signal / channel, the terminal device receives the first downlink signal / channel on the third time-frequency resource, and cancels or partially cancels the sending of the first uplink signal / channel on the first time-frequency resource according to the priority of the first uplink signal / channel and the priority of the first downlink signal / channel; the third time-frequency resource is the overlapping part of the first time-frequency resource and the second time-frequency resource.

[0145] Accordingly, when the first time-frequency resource occupied by the first uplink signal / channel overlaps with the second time-frequency resource occupied by the first downlink signal / channel, the network device receives the first uplink signal / channel on the third time-frequency resource and cancels or partially cancels the sending of the first downlink signal / channel on the second time-frequency resource based on the priority of the first uplink signal / channel and the priority of the first downlink signal / channel; or, when the first time-frequency resource occupied by the first uplink signal / channel overlaps with the second time-frequency resource occupied by the first downlink signal / channel, the network device sends the first downlink signal / channel on the third time-frequency resource and cancels or partially cancels the reception of the first uplink signal / channel on the first time-frequency resource based on the priority of the first uplink signal / channel and the priority of the first downlink signal / channel; the third time-frequency resource is the overlapping part of the first time-frequency resource and the second time-frequency resource.

[0146] The first time-frequency resource occupied by the first uplink signal / channel may be the time-frequency resource used by the terminal device to send the first uplink signal / channel, or may be the time-frequency resource used by the network device to receive the first uplink signal / channel. The second time-frequency resource occupied by the first downlink signal / channel may be the time-frequency resource used by the terminal device to receive the first downlink signal / channel, or may be the time-frequency resource used by the network device to send the first downlink signal / channel.

[0147] The third time-frequency resource is the overlapping part of the first time-frequency resource and the second time-frequency resource, that is, the third time-frequency resource is the overlapping time-frequency resource between the first time-frequency resource and the second time-frequency resource. Figure 9 is a schematic diagram of resource distribution. Figure 9 As shown, the first time-frequency resource is a time-frequency resource occupying t1 to t3 in the time domain and f2 to f4 in the frequency domain; the second time-frequency resource is a time-frequency resource occupying t2 to t4 in the time domain and f1 to f3 in the frequency domain; the third time-frequency resource is a time-frequency resource occupying t2 to t3 in the time domain and f2 to f3 in the frequency domain, that is, the third time-frequency resource is Figure 9 The time-frequency resources represented by the slashed part. For example, Figure 10 This is a distribution diagram of another resource. Figure 10 This is another resource distribution diagram. Figure 10 As shown, the first time-frequency resource is a time-frequency resource occupying t1 to t3 in the time domain and f1 to f2 in the frequency domain; the second time-frequency resource is a time-frequency resource occupying t2 to t4 in the time domain and f1 to f2 in the frequency domain; the third time-frequency resource is a time-frequency resource occupying t2 to t3 in the time domain and f1 to f2 in the frequency domain, that is, the third time-frequency resource is Figure 10 The time-frequency resources represented by the slashed part.

[0148] In an optional implementation, the first uplink signal / channel may be one of a random access channel (RACH), a PUCCH, a PUSCH, uplink control information (UCI), and an SRS. The first downlink signal / channel may be one of a physical downlink control channel (PDCCH), a PDSCH, a DCI, and a downlink reference signal.

[0149] It is understandable that the embodiments of the present application do not limit the specific implementation of the first uplink signal / channel and the specific implementation of the first downlink signal / channel.

[0150] The specific implementation of S101 is described below:

[0151] Implementation method 1: The terminal device determines signal transmission on the third time-frequency resource according to the priority of the first uplink signal / channel and the priority of the first downlink signal / channel.

[0152] In an optional embodiment, the terminal device sends the first uplink signal / channel on the third time-frequency resource and cancels or partially cancels the reception of the first downlink signal / channel on the second time-frequency resource based on the priority of the first uplink signal / channel and the priority of the first downlink signal / channel, including: when the priority of the first uplink signal / channel is higher than the priority of the first downlink signal / channel, sending the first uplink signal / channel on the third time-frequency resource and canceling or partially canceling the reception of the first downlink signal / channel on the second time-frequency resource.

[0153] It can be seen that when the priority of the first uplink signal / channel is higher than the priority of the first downlink signal / channel, the terminal device gives priority to ensuring the transmission of the first uplink signal / channel, thereby canceling or partially canceling the reception of the first downlink signal / channel on the second time-frequency resource, thereby improving the accuracy of the reception of the first downlink signal / channel.

[0154] Optionally, the terminal device partially cancels reception of the first downlink signal / channel on the second time-frequency resource, including: receiving the first downlink signal / channel on a fourth time-frequency resource, and canceling reception of the first downlink signal / channel on a third time-frequency resource. The fourth time-frequency resource is a portion of the second time-frequency resource that does not overlap with the first time-frequency resource.

[0155] For example, Figure 9 As shown, the fourth time-frequency resource is as follows Figure 9 As shown in the dark black pattern. Then, the terminal device Figure 9The first uplink signal / channel is sent on the time-frequency resource shown in the light gray and oblique pattern portion, and the reception of the first downlink signal / channel on the time-frequency resource shown in the dark black and oblique pattern portion is canceled. Alternatively, the terminal device Figure 9 The first downlink signal / channel is received on the time-frequency resource shown in the dark black pattern portion, and Figure 9 The first uplink signal / channel is sent on the time-frequency resources shown in the light gray and oblique line pattern parts.

[0156] For example, Figure 10 As shown, the fourth time-frequency resource is as follows Figure 10 As shown in the dark black pattern. Then, the terminal device Figure 10 The first uplink signal / channel is sent on the time-frequency resource shown in the light gray and oblique pattern portion, and the reception of the first downlink signal / channel on the time-frequency resource shown in the dark black and oblique pattern portion is canceled. Alternatively, the terminal device Figure 10 The first downlink signal / channel is received on the time-frequency resource shown in the dark black pattern portion, and Figure 10 The first uplink signal / channel is sent on the time-frequency resources shown in the light gray and oblique line pattern parts.

[0157] Accordingly, the network device receives the first uplink signal / channel on the third time-frequency resource and cancels or partially cancels the sending of the first downlink signal / channel on the second time-frequency resource based on the priority of the first uplink signal / channel and the priority of the first downlink signal / channel, including: when the priority of the first uplink signal / channel is higher than the priority of the first downlink signal / channel, receiving the first uplink signal / channel on the third time-frequency resource and canceling or partially canceling the sending of the first downlink signal / channel on the second time-frequency resource.

[0158] Optionally, the network device partially cancels the sending of the first downlink signal / channel on the second time-frequency resource, including: sending the first downlink signal / channel on the fourth time-frequency resource, and canceling the sending of the first downlink signal / channel on the third time-frequency resource.

[0159] For example, network devices in Figure 9 The first uplink signal / channel is received on the time-frequency resource shown in the light gray and oblique pattern portion, and the transmission of the first downlink signal / channel on the time-frequency resource shown in the dark black and oblique pattern portion is canceled. Alternatively, the network device Figure 9 The first downlink signal / channel is sent on the time-frequency resource shown in the dark black pattern portion, and Figure 9 The first uplink signal / channel is received on the time-frequency resources shown in the light gray and oblique line pattern parts.

[0160] For example, network devices in Figure 10The first uplink signal / channel is received on the time-frequency resource shown in the light gray and oblique pattern portion, and the transmission of the first downlink signal / channel on the time-frequency resource shown in the dark black and oblique pattern portion is canceled. Alternatively, the network device Figure 10 The first downlink signal / channel is sent on the time-frequency resource shown in the dark black pattern portion, and Figure 10 The first uplink signal / channel is received on the time-frequency resources shown in the light gray and oblique line pattern parts.

[0161] Optionally, when the priority of the first uplink signal / channel is higher than the priority of the first downlink signal / channel, the terminal device sends the first uplink signal / channel on the third time-frequency resource and can receive the first downlink signal / channel on the second time-frequency resource. Correspondingly, when the priority of the first uplink signal / channel is higher than the priority of the first downlink signal / channel, the network device receives the first uplink signal / channel on the third time-frequency resource and can send the first downlink signal / channel on the second time-frequency resource.

[0162] In another optional implementation, the terminal device receives the first downlink signal / channel on the third time-frequency resource and cancels or partially cancels the transmission of the first uplink signal / channel on the first time-frequency resource based on the priority of the first uplink signal / channel and the priority of the first downlink signal / channel, including: when the priority of the first uplink signal / channel is lower than the priority of the first downlink signal / channel, receiving the first downlink signal / channel on the third time-frequency resource and canceling or partially canceling the transmission of the first uplink signal / channel on the first time-frequency resource.

[0163] It can be seen that when the priority of the first uplink signal / channel is lower than the priority of the first downlink signal / channel, the terminal device gives priority to ensuring the reception of the first downlink signal / channel, thereby canceling or partially canceling the transmission of the first uplink signal / channel on the first time-frequency resource, thereby improving the accuracy of the reception of the first downlink signal / channel.

[0164] Optionally, the terminal device partially cancels the transmission of the first uplink signal / channel on the first time-frequency resource, including: sending the first uplink signal / channel on the fifth time-frequency resource, and canceling the transmission of the first uplink signal / channel on the third time-frequency resource. The fifth time-frequency resource is the portion of the first time-frequency resource that does not overlap with the second time-frequency resource.

[0165] For example, Figure 9 As shown, the fifth time-frequency resource is as follows Figure 9 As shown in the light grey pattern. Then, the terminal device Figure 9 The first downlink signal / channel is received on the time-frequency resource shown in the dark black and oblique pattern portion, and the transmission of the first uplink signal / channel on the time-frequency resource shown in the light gray and oblique pattern portion is canceled. Alternatively, the terminal device receives the first downlink signal / channel on the time-frequency resource shown in the dark black and oblique pattern portion, and cancels the transmission of the first uplink signal / channel on the time-frequency resource shown in the light gray and oblique pattern portion. Figure 9 The first uplink signal / channel is sent on the time-frequency resource shown in the light grey pattern portion, and Figure 9 The first downlink signal / channel is received on the time-frequency resources shown in the dark black and oblique line pattern parts.

[0166] For example, Figure 10 As shown, the fifth time-frequency resource is as follows Figure 10 As shown in the light grey pattern. Then, the terminal device Figure 10 The first downlink signal / channel is received on the time-frequency resource shown in the dark black and oblique pattern portion, and the transmission of the first uplink signal / channel on the time-frequency resource shown in the light gray and oblique pattern portion is canceled. Alternatively, the terminal device receives the first downlink signal / channel on the time-frequency resource shown in the dark black and oblique pattern portion, and cancels the transmission of the first uplink signal / channel on the time-frequency resource shown in the light gray and oblique pattern portion. Figure 10 The first uplink signal / channel is sent on the time-frequency resource shown in the light grey pattern portion, and Figure 10 The first downlink signal / channel is received on the time-frequency resources shown in the dark black and oblique line pattern parts.

[0167] Accordingly, the network device sends the first downlink signal / channel on the third time-frequency resource and cancels or partially cancels the reception of the first uplink signal / channel on the first time-frequency resource according to the priority of the first uplink signal / channel and the priority of the first downlink signal / channel, including: when the priority of the first uplink signal / channel is lower than the priority of the first downlink signal / channel, sending the first downlink signal / channel on the third time-frequency resource and canceling or partially canceling the reception of the first uplink signal / channel on the first time-frequency resource.

[0168] Optionally, the network device partially cancels reception of the first uplink signal / channel on the first time-frequency resource, including: receiving the first uplink signal / channel on the fifth time-frequency resource, and canceling reception of the first uplink signal / channel on the third time-frequency resource.

[0169] For example, network devices in Figure 9 The first downlink signal / channel is sent on the time-frequency resource shown in the dark black and oblique pattern portion, and the reception of the first uplink signal / channel on the time-frequency resource shown in the light gray and oblique pattern portion is canceled. Alternatively, the network device Figure 9 The first uplink signal / channel is received on the time-frequency resource shown in the light grey pattern portion, and Figure 9 The first downlink signal / channel is sent on the time-frequency resources shown in the dark black and oblique line pattern parts.

[0170] For example, Figure 10 As shown, the network equipment is Figure 10The first downlink signal / channel is sent on the time-frequency resource shown in the dark black and oblique pattern portion, and the reception of the first uplink signal / channel on the time-frequency resource shown in the light gray and oblique pattern portion is canceled. Alternatively, the terminal device Figure 10 The first uplink signal / channel is received on the time-frequency resource shown in the light grey pattern portion, and Figure 10 The first downlink signal / channel is sent on the time-frequency resources shown in the dark black and oblique line pattern parts.

[0171] In an optional embodiment, the terminal device further determines first configuration information, where the first configuration information includes a priority between one or more uplink signals / channels and one or more downlink signals / channels, wherein the one or more uplink signals / channels include a first uplink signal / channel, and the one or more downlink signals / channels include a first downlink signal / channel.

[0172] Optionally, the terminal device determines the first configuration information, including: receiving the first configuration information from the network device. Optionally, the terminal device determines the first configuration information, including: the terminal device negotiates the first configuration information with the network device, that is, the first configuration information may be pre-negotiated between the network device and the terminal device.

[0173] Exemplarily, the first configuration information includes the priority of each signal of PUSCH, PUCCH, PDSCH and PDCCH, and the priority relationship between the four signals is: PDCCH>PUCCH>PUSCH>PDSCH. The first uplink signal / channel is PUSCH, and the first downlink signal / channel is PDSCH. When the first time-frequency resource occupied by PUSCH overlaps with the second time-frequency resource occupied by PDSCH, PUSCH has a higher priority than PDSCH, and the terminal device sends PUSCH on the third time-frequency resource, and cancels or partially cancels the reception of PDSCH on the second time-frequency resource.

[0174] Exemplarily, the first configuration information includes the priority of each signal of PUSCH, PUCCH, PDSCH and PDCCH, and the priority relationship between the four signals is: PDCCH>PUCCH>PDSCH>PUSCH. The first uplink signal / channel is PUSCH, and the first downlink signal / channel is PDSCH. When the first time-frequency resource occupied by PUSCH overlaps with the second time-frequency resource occupied by PDSCH, PDSCH has a higher priority than PUSCH, and the terminal device receives PDSCH on the third time-frequency resource, and cancels or partially cancels the transmission of PUSCH on the first time-frequency resource.

[0175] Correspondingly, the network device may also determine first configuration information, where the first configuration information includes priorities between one or more uplink signals / channels and one or more downlink signals / channels.

[0176] Implementation method 2: The terminal device determines signal transmission on the third time-frequency resource according to the priority of the first uplink signal / channel and the priority of the first downlink signal / channel, as well as the first threshold and the second threshold.

[0177] In an optional implementation, the terminal device sends the first uplink signal / channel on the third time-frequency resource and cancels or partially cancels the reception of the first downlink signal / channel on the second time-frequency resource based on the priority of the first uplink signal / channel and the priority of the first downlink signal / channel, including: when the priority of the first uplink signal / channel is greater than the first threshold and the priority of the first downlink signal / channel is less than the second threshold, sending the first uplink signal / channel on the third time-frequency resource and canceling or partially canceling the reception of the first downlink signal / channel on the second time-frequency resource.

[0178] The first threshold is determined by the priority among multiple uplink signals / channels, and the second threshold is determined by the priority among multiple downlink signals / channels. The multiple uplink signals / channels include the first uplink signal / channel, and the multiple downlink signals / channels include the first downlink signal / channel.

[0179] It can be seen that when the priority of the first uplink signal / channel of the terminal device is greater than the first threshold and the priority of the first downlink signal / channel is less than the second threshold, the transmission of the first uplink signal / channel is prioritized, thereby canceling or partially canceling the reception of the first downlink signal / channel on the second time-frequency resource, which can ensure the reception of the first uplink signal / channel on the network device side and ensure the reception of part of the first downlink signal / channel on the terminal device side.

[0180] Accordingly, the network device receives the first uplink signal / channel on the third time-frequency resource and cancels or partially cancels the sending of the first downlink signal / channel on the second time-frequency resource based on the priority of the first uplink signal / channel and the priority of the first downlink signal / channel, including: when the priority of the first uplink signal / channel is greater than the first threshold and the priority of the first downlink signal / channel is less than the second threshold, receiving the first uplink signal / channel on the third time-frequency resource and canceling or partially canceling the sending of the first downlink signal / channel on the second time-frequency resource.

[0181] Among them, the implementation method of the terminal device partially canceling the reception of the first downlink signal / channel on the second time-frequency resource, and the implementation method of the network device partially canceling the transmission of the first downlink signal / channel on the second time-frequency resource can be referred to the above implementation method 1 and will not be repeated here.

[0182] In another optional implementation, the terminal device receives the first downlink signal / channel on the third time-frequency resource and cancels or partially cancels the transmission of the first uplink signal / channel on the first time-frequency resource based on the priority of the first uplink signal / channel and the priority of the first downlink signal / channel, including: when the priority of the first uplink signal / channel is less than the first threshold and the priority of the first downlink signal / channel is greater than the second threshold, receiving the first downlink signal / channel on the third time-frequency resource and canceling or partially canceling the transmission of the first uplink signal / channel on the first time-frequency resource.

[0183] It can be seen that when the priority of the first uplink signal / channel is less than the first threshold and the priority of the first downlink signal / channel is greater than the second threshold, the terminal device gives priority to ensuring the reception of the first downlink signal / channel, thereby canceling or partially canceling the transmission of the first uplink signal / channel on the first time-frequency resource, thereby improving the accuracy of the reception of the first downlink signal / channel.

[0184] Accordingly, the network device sends the first downlink signal / channel on the third time-frequency resource and cancels or partially cancels the reception of the first uplink signal / channel on the first time-frequency resource based on the priority of the first uplink signal / channel and the priority of the first downlink signal / channel, including: when the priority of the first uplink signal / channel is less than the first threshold and the priority of the first downlink signal / channel is greater than the second threshold, sending the first downlink signal / channel on the third time-frequency resource and canceling or partially canceling the reception of the first uplink signal / channel on the first time-frequency resource.

[0185] Among them, the implementation method of the terminal device partially canceling the sending of the first uplink signal / channel on the first time-frequency resource, and the implementation method of the network device partially canceling the receiving of the first uplink signal / channel on the first time-frequency resource can be referred to the above implementation method 1 and will not be repeated here.

[0186] In an optional embodiment, the terminal device further determines second configuration information, the second configuration information including priorities among multiple uplink signals / channels and priorities among multiple downlink signals / channels, wherein the multiple uplink signals / channels include a first uplink signal / channel, and the multiple downlink signals / channels include a first downlink signal / channel.

[0187] Optionally, the terminal device determines the second configuration information, including: the terminal device receives the second configuration information from the network device. Optionally, the terminal device determines the second configuration information, including: the terminal device negotiates the second configuration information with the network device, that is, the second configuration information can be pre-negotiated between the network device and the terminal device.

[0188] Optionally, the second configuration information may include a first threshold and a second threshold. The first threshold is determined by the priority between multiple uplink signals / channels, and the second threshold is determined by the priority between multiple downlink signals / channels. For example, the first threshold is determined by the priority between PUSCH and PUCCH, and the second threshold is determined by the priority between PDSCH and PDCCH.

[0189] Exemplarily, the second configuration information includes priorities among PRACH, SRS, PUSCH, and PUCCH, as well as priorities among synchronization signal blocks (SSB), channel state information reference signals (CSI-RS), phase tracking reference signals (PTRS), positioning reference signals (PRS), PDSCH, and PDCCH. The priority relationship among PRACH, SRS, PUSCH, and PUCCH is: PRACH>PUCCH>PUSCH>SRS, and the priority relationship among SSB, CSI-RS, PTRS, PRS, PDSCH, and PDCCH is: SSB>PDCCH>PDSCH>CSI-RS>PTRS>PRS. The first uplink signal / channel is PUCCH, the first downlink signal / channel is PDSCH, the first threshold is the priority of PUSCH, and the second threshold is the priority of PDCCH. When the first time-frequency resources occupied by PUCCH overlap with the second time-frequency resources occupied by PDSCH, and the priority of PUCCH is higher than the priority of PUSCH, and the priority of PDSCH is lower than the priority of PDCCH, the terminal device sends PUCCH on the third time-frequency resources, and cancels or partially cancels the reception of PDSCH on the second time-frequency resources.

[0190] Exemplarily, the second configuration information includes priorities among PRACH, SRS, PUSCH, and PUCCH, and priorities among SSB, CSI-RS, PTRS, PRS, PDSCH, and PDCCH. The priority relationship among PRACH, SRS, PUSCH, and PUCCH is: PRACH>PUCCH>PUSCH>SRS, and the priority relationship among SSB, CSI-RS, PTRS, PRS, PDSCH, and PDCCH is: SSB>PDCCH>PDSCH>CSI-RS>PTRS>PRS. The first uplink signal / channel is PUSCH, the first downlink signal / channel is PDCCH, the first threshold is the priority of PUCCH, and the second threshold is the priority of PDSCH. When the first time-frequency resource occupied by PUSCH overlaps with the second time-frequency resource occupied by PDCCH, and the priority of PUSCH is lower than the priority of PUCCH, and the priority of PDCCH is higher than the priority of PDSCH, the terminal device receives PDCCH on the third time-frequency resource, and cancels or partially cancels the transmission of PUSCH on the first time-frequency resource.

[0191] Correspondingly, the network device may also determine second configuration information, where the second configuration information includes priorities among multiple uplink signals / channels and priorities among multiple downlink signals / channels.

[0192] Optionally, a numerical value may be used to represent the priority. For example, the larger the numerical value of the priority of the first uplink signal / channel, the higher the priority of the first uplink signal / channel; or, the smaller the numerical value of the priority of the first uplink signal / channel, the higher the priority of the first uplink signal / channel. The relationship between the numerical value of the priority of the first downlink signal / channel and the priority is similar, and the embodiments of the present application do not limit this. Optionally, the priority may also be represented by letters. For example, A, B, and C are used to represent the priority of the first uplink signal / channel, and the priority represented by A is higher than the priority represented by B, and the priority represented by B is higher than the priority represented by C. Optionally, the priority may also be represented by levels. For example, the first level, the second level, and the third level are used to represent the priority of the first uplink signal / channel, and the priority represented by the first level is higher than the priority represented by the second level, and the priority represented by the second level is higher than the priority represented by the third level.

[0193] When the priority value of the first uplink signal / channel is smaller, indicating that the priority of the first uplink signal / channel is higher, the terminal device receives the first downlink signal / channel on the third time-frequency resource and cancels or partially cancels the sending of the first uplink signal / channel on the first time-frequency resource according to the priority of the first uplink signal / channel and the priority of the first downlink signal / channel, including: when the priority of the first uplink signal / channel is greater than the first threshold and the priority of the first downlink signal / channel is less than the second threshold, receiving the first downlink signal / channel on the third time-frequency resource and canceling or partially canceling the sending of the first uplink signal / channel on the first time-frequency resource.

[0194] Optionally, different contents of the same signal / channel may have different priorities. For example, the priority relationship among HARQ, CSI part 1, and CSI part 2 in UCI is: HARQ > CSI part 1 > CSI part 2.

[0195] In an embodiment of the present application, when the first time-frequency resource occupied by the first uplink signal / channel overlaps with the second time-frequency resource occupied by the first downlink signal / channel, the terminal device sends the first uplink signal / channel on the third time-frequency resource and cancels or partially cancels the reception of the first downlink signal / channel on the second time-frequency resource based on the priority of the first uplink signal / channel and the priority of the first downlink signal / channel; or receives the first downlink signal / channel on the third time-frequency resource and cancels or partially cancels the transmission of the first uplink signal / channel on the first time-frequency resource based on the priority of the first uplink signal / channel and the priority of the first downlink signal / channel. The third time-frequency resource is the overlapping portion of the first time-frequency resource and the second time-frequency resource.

[0196] It can be seen that when the first time-frequency resource occupied by the uplink signal / channel of the terminal device overlaps with the second time-frequency resource occupied by the downlink signal / channel, the terminal device determines to send the uplink signal / channel or receive the downlink signal / channel on the overlapping time-frequency resource between the first time-frequency resource and the second time-frequency resource according to the priority of the uplink signal / channel and the priority of the downlink signal / channel. This can reduce self-interference in simultaneous co-frequency full-duplex, thereby ensuring the reception of the first uplink signal / channel on the network device side, and ensuring the reception of part of the first downlink signal / channel on the terminal device side.

[0197] This embodiment of the application proposes a communication method 200. Figure 11 2 is a flow chart of a communication method 200, which includes but is not limited to:

[0198] S201. The terminal device determines a transmission direction on a sixth time-frequency resource, and the sixth time-frequency resource supports a half-duplex communication mode.

[0199] The sixth time-frequency resource is a time-frequency resource that supports half-duplex communication mode. On the sixth time-frequency resource, a terminal device can transmit the first uplink signal / channel at a certain time but cannot receive the first downlink signal / channel; alternatively, on the sixth time-frequency resource, a terminal device can receive the first downlink signal / channel at a certain time but cannot transmit the first uplink signal / channel. In other words, for the sixth time-frequency resource, a terminal device cannot simultaneously transmit the first uplink signal / channel and receive the first downlink signal / channel.

[0200] Correspondingly, the network device can also determine the transmission direction on the sixth time-frequency resource, and the sixth time-frequency resource supports a half-duplex communication mode.

[0201] S202: The terminal device cancels the transmission in the opposite direction of the transmission. Correspondingly, the network device cancels the transmission in the opposite direction of the transmission.

[0202] In an optional implementation, the terminal device determines a transmission direction on a sixth time-frequency resource and cancels transmission opposite to the transmission direction, including: determining third configuration information, where the third configuration information is used to configure the transmission direction on the sixth time-frequency resource. Based on the third configuration information, the terminal device determines the transmission direction on the sixth time-frequency resource and cancels transmission opposite to the transmission direction.

[0203] Optionally, the terminal device determines the third configuration information, including: receiving the third configuration information from the network device. Optionally, the terminal device determines the third configuration information, including: the terminal device negotiates the third configuration information with the network device, that is, the third configuration information may be pre-negotiated between the network device and the terminal device.

[0204] It can be seen that the terminal device can determine the transmission direction on the sixth time-frequency resource based on the third configuration information, and cancel the transmission opposite to the transmission direction on the sixth time-frequency resource, thereby ensuring the transmission direction on the sixth time-frequency resource, and further improving the accuracy of receiving downlink signals / channels on the sixth time-frequency resource.

[0205] Optionally, the terminal device determines the transmission direction on the sixth time-frequency resource based on the third configuration information, and cancels the transmission opposite to the transmission direction, including: when the third configuration information is uplink transmission, determining the transmission direction on the sixth time-frequency resource as uplink transmission, and canceling the downlink transmission on the sixth time-frequency resource; when the third configuration information is downlink transmission, determining the transmission direction on the sixth time-frequency resource as downlink transmission, and canceling the uplink transmission on the sixth time-frequency resource.

[0206] In an optional implementation, the terminal device determines the transmission direction on the sixth time-frequency resource and cancels the transmission opposite to the transmission direction, including: when the priority of the first uplink signal / channel is higher than the priority of the first downlink signal / channel, determining the transmission direction on the sixth time-frequency resource as uplink transmission and canceling the downlink transmission on the sixth time-frequency resource; when the priority of the first uplink signal / channel is lower than the priority of the first downlink signal / channel, the terminal device determines the transmission direction on the sixth time-frequency resource as downlink transmission and cancels the uplink transmission on the sixth time-frequency resource. The first time-frequency resource occupied by the first uplink signal / channel and the second time-frequency resource occupied by the first downlink signal / channel overlap with the sixth time-frequency resource.

[0207] Among them, when the priority of the first uplink signal / channel of the terminal device is higher than the priority of the first downlink signal / channel, the terminal device determines that the transmission direction on the sixth time-frequency resource is uplink transmission, and cancels the downlink transmission on the sixth time-frequency resource, which means: when the priority of the first uplink signal / channel is higher than the priority of the first downlink signal / channel, the first uplink signal / channel is sent on the sixth time-frequency resource, and the reception of the first downlink signal / channel on the sixth time-frequency resource is canceled. When the priority of the first uplink signal / channel of the terminal device is lower than the priority of the first downlink signal / channel, the terminal device determines that the transmission direction on the sixth time-frequency resource is downlink transmission, and cancels the uplink transmission on the sixth time-frequency resource, which means: when the priority of the first uplink signal / channel is lower than the priority of the first downlink signal / channel, the first downlink signal / channel is received on the sixth time-frequency resource, and the sending of the first uplink signal / channel on the sixth time-frequency resource is canceled.

[0208] In an optional implementation, the terminal device determines first configuration information, where the first configuration information includes priorities between one or more uplink signals / channels and one or more downlink signals / channels. The one or more uplink signals / channels include a first uplink signal / channel, and the one or more downlink signals / channels include a first downlink signal / channel. The implementation method for the terminal device to determine the first configuration information can be found in the above implementation method and will not be repeated here.

[0209] Exemplarily, the first configuration information includes the priority of each signal of PUSCH, PUCCH, PDSCH and PDCCH, and the priority relationship between the four signals is: PDCCH>PUCCH>PUSCH>PDSCH. The first uplink signal / channel is PUSCH, and the first downlink signal / channel is PDSCH. The terminal device determines that the transmission direction on the sixth time-frequency resource is uplink transmission, and cancels the downlink transmission on the sixth time-frequency resource.

[0210] Exemplarily, the first configuration information includes the priority of each signal of PUSCH, PUCCH, PDSCH and PDCCH, and the priority relationship between the four signals is: PDCCH>PUCCH>PDSCH>PUSCH. The first uplink signal / channel is PUSCH, and the first downlink signal / channel is PDSCH. The terminal device determines that the transmission direction on the sixth time-frequency resource is downlink transmission, and cancels the uplink transmission on the sixth time-frequency resource.

[0211] In another optional implementation, the terminal device determines the transmission direction on the sixth time-frequency resource and cancels the transmission opposite to the transmission direction, including: when the priority of the first uplink signal / channel is greater than the first threshold and the priority of the first downlink signal / channel is less than the second threshold, the transmission direction on the sixth time-frequency resource is determined to be uplink transmission, and the downlink transmission on the sixth time-frequency resource is canceled; when the priority of the first uplink signal / channel is less than the first threshold and the priority of the first downlink signal / channel is greater than the second threshold, the terminal device determines the transmission direction on the sixth time-frequency resource to be downlink transmission, and cancels the uplink transmission on the sixth time-frequency resource. The first time-frequency resource occupied by the first uplink signal / channel and the second time-frequency resource occupied by the first downlink signal / channel overlap with the sixth time-frequency resource.

[0212] In an optional embodiment, the terminal device determines second configuration information, where the second configuration information includes priorities among multiple uplink signals / channels and priorities among multiple downlink signals / channels, wherein the multiple uplink signals / channels include a first uplink signal / channel, and the multiple downlink signals / channels include a first downlink signal / channel.

[0213] Among them, the implementation method for the terminal device to determine the second configuration information can be referred to the above implementation method and will not be repeated here.

[0214] Exemplarily, the second configuration information includes the priorities among PRACH, SRS, PUSCH and PUCCH, and the priorities among SSB, CSI-RS, PTRS, PRS, PDSCH and PDCCH. The priority relationship among PRACH, SRS, PUSCH and PUCCH is: PRACH>PUCCH>PUSCH>SRS, and the priority relationship among SSB, CSI-RS, PTRS, PRS, PDSCH and PDCCH is: SSB>PDCCH>PDSCH>CSI-RS>PTRS>PRS. The first uplink signal / channel is PUCCH, the first downlink signal / channel is PDSCH, the first threshold is the priority of PUSCH, and the second threshold is the priority of PDCCH. The priority of PUCCH is higher than that of PUSCH, and the priority of PDSCH is lower than that of PDCCH. The terminal device determines that the transmission direction on the sixth time-frequency resource is uplink transmission, and cancels the downlink transmission on the sixth time-frequency resource.

[0215] Exemplarily, the second configuration information includes the priorities among PRACH, SRS, PUSCH and PUCCH, and the priorities among SSB, CSI-RS, PTRS, PRS, PDSCH and PDCCH. The priority relationship among PRACH, SRS, PUSCH and PUCCH is: PRACH>PUCCH>PUSCH>SRS, and the priority relationship among SSB, CSI-RS, PTRS, PRS, PDSCH and PDCCH is: SSB>PDCCH>PDSCH>CSI-RS>PTRS>PRS. The first uplink signal / channel is PUSCH, the first downlink signal / channel is PDCCH, the first threshold is the priority of PUCCH, and the second threshold is the priority of PDSCH. The priority of PUSCH is lower than the priority of PUCCH, and the priority of PDCCH is higher than the priority of PDSCH. The terminal device determines that the transmission direction on the sixth time-frequency resource is downlink transmission, and cancels the uplink transmission on the sixth time-frequency resource.

[0216] In this embodiment of the present application, a terminal device determines a transmission direction on a sixth time-frequency resource that supports a half-duplex communication mode. The terminal device cancels transmissions in the opposite direction of the transmission direction. Thus, the terminal device can determine a transmission direction on a time-frequency resource that supports a half-duplex communication mode and cancel transmissions in the opposite direction of the transmission direction, thereby reducing self-interference in simultaneous, co-frequency, full-duplex communication.
