[0157] Therefore, as an embodiment, the terminal does not expect the transmissions of the first downlink channel and the second uplink channel to overlap in the time domain, and can also be described in any of the following forms:

[0158] 1) The terminal expects the transmissions of the first downlink channel and the second uplink channel not to overlap in the time domain;

[0159] 2) The UE behavior when the transmissions of the first downlink channel and the second uplink channel overlap in the time domain is undefined;

[0160] 3) There is no restriction on the behavior of the terminal when the transmission of the first downlink channel and the transmission of the second uplink channel overlap in the time domain;

[0161] 4) If the transmission of the first downlink channel and the transmission of the second uplink channel overlap in the time domain, the terminal will ignore or not execute the corresponding configuration or indication of the network;

[0162] 5) It is recommended that the base station not configure / indicate that the transmission of the first downlink channel and the transmission of the second uplink channel overlap in the time domain.

[0163] The undefined terminal behavior means that when the terminal receives an unexpected network configuration / indication, the behavior of the terminal is undefined. At this time, the terminal may adopt any behavior. For example, in this solution, when the terminal receives an unexpected network configuration / indication, the terminal can choose to receive the first downlink channel, or transmit the second uplink channel, or neither receive the first downlink channel nor transmit the second uplink channel.

[0164] Optionally, the first action can be performed according to the authorization or scheduling method of the first downlink channel and the second uplink channel, or the timing relationship between the authorization or scheduling of the first downlink channel and the authorization or scheduling of the second uplink channel. The above terminal performing the first action according to the first information may include any of the following:

[0165] When the transmission of the first downlink channel and the transmission of the second uplink channel will overlap in the time domain, if the first downlink channel is scheduled by a first Downlink Control Information (DCI) format and the second uplink channel is scheduled by a second DCI format, the terminal performs the first operation or the second operation according to the order of the reception time of the Physical Downlink Control Channel (PDCCH) of the first DCI format and the reception time of the PDCCH of the second DCI format;

[0166] When the transmission of the first downlink channel and the transmission of the second uplink channel will overlap in the time domain, if the first downlink channel is scheduled by a third DCI format and the second uplink channel is configured with a grant, the terminal performs the first operation;

[0167] When the transmission of the first downlink channel and the transmission of the second uplink channel will overlap in the time domain, if the first downlink channel is configured with a grant and the second uplink channel is scheduled by a fourth DCI format, the terminal performs the second operation.

[0168] It should be noted that the first downlink channel is scheduled by the first DCI format, and can also be referred to as: the first downlink channel is dynamically granted DG, the first downlink channel is dynamically allocated downlink reception, etc.

[0169] The second uplink channel is scheduled by the second DCI format, and can also be referred to as: the second uplink channel is dynamically granted DG, the second uplink channel is dynamically allocated uplink transmission, etc.

[0170] The second uplink channel is configured with a grant, and can also be referred to as: the second uplink channel is a configured uplink grant, etc.

[0171] The first downlink channel is configured with a grant, and can also be referred to as: the first downlink channel is a configured downlink assignment, the first downlink channel is semi-persistent scheduling SPS, etc.

[0172] The DCI format can be abbreviated as DCI.

[0173] The reception time of the PDCCH of the first / second DCI format can also be referred to as: the reception time of the DCI corresponding to the first / second DCI format.

[0174] The "sequence relationship between the reception time of the PDCCH of the first DCI format and the reception time of the PDCCH of the second DCI format" can also be referred to as: the timing relationship between the reception time of the PDCCH of the first DCI format and the reception time of the PDCCH of the second DCI format.

[0175] Performing the first operation or the second operation according to the sequence relationship between the reception time of the PDCCH of the first DCI format and the reception time of the PDCCH of the second DCI format can also be expressed as: performing the first operation or the second operation according to the sequence relationship between the reception time of the first DCI and the reception time of the second DCI; or can be expressed as: performing the first operation or the second operation according to the timing relationship between the reception time of the PDCCH of the first DCI format and the reception time of the PDCCH of the second DCI format.

[0176] Optionally, performing the first operation or the second operation according to the order relationship between the reception time of the PDCCH of the first DCI format and the reception time of the PDCCH of the second DCI format may include at least one of the following:

[0177] (1) If the reception time of the PDCCH of the first DCI format is later than the reception time of the PDCCH of the second DCI format, the terminal performs the first operation;

[0178] For example Figure 2A As described above, if the first DCI schedules the first downlink channel (such as PDSCH), the second DCI schedules the second uplink channel (such as PUSCH), and the reception time of the first DCI is later than the reception time of the second DCI, then the UE receives the first downlink channel (such as PDSCH) and abandons / does not transmit the second uplink channel (such as PUSCH).

[0179] (2) If the end symbol of the PDCCH of the first DCI format is later than the end symbol of the PDCCH of the second DCI format, and the end symbol of the PDCCH of the first DCI format is before the start symbol of the second uplink channel, and the time interval between the end symbol of the PDCCH of the first DCI format and the start symbol of the second uplink channel is greater than or equal to the first duration, the terminal performs the first operation; the first duration can be agreed upon by the protocol or pre-configured, etc., for example, it is equal to M1 symbols, and M1 is a non-negative number;

[0180] Optionally, if the end symbol of the PDCCH of the first DCI format is later than the end symbol of the PDCCH of the second DCI format, and the end symbol of the PDCCH of the first DCI format is before the start symbol of the second uplink channel, and the time interval between the end symbol of the PDCCH of the first DCI format and the start symbol of the second uplink channel is greater than or equal to M1 symbols, the terminal determines to perform the first operation, where M1 is a non-negative number;

[0181] For example Figure 2B As described above, if the first DCI schedules the first downlink channel (such as PDSCH), the second DCI schedules the second uplink channel (such as PUSCH), the end symbol of the first DCI is later than the end symbol of the second DCI, and the end symbol i of the first DCI is before the start symbol j of the second uplink channel (such as PUSCH), and the time interval between the end symbol i of the first DCI format and the start symbol j of the second uplink channel (such as PUSCH) is greater than or equal to M1 symbols, then the UE receives the first downlink channel (such as PDSCH) and abandons / does not transmit the second uplink channel (such as PUSCH).

[0182] (3) If the reception time of the PDCCH of the second DCI format is later than the reception time of the PDCCH of the first DCI format, the terminal performs the second operation;

[0183] For example Figure 2C as described above, if the first DCI schedules a first downlink channel (such as PDSCH), the second DCI schedules a second uplink channel (such as PUSCH), the reception time of the second DCI is later than the reception time of the first DCI, then the UE transmits the second uplink channel (such as PUSCH), and abandons receiving / does not receive the first downlink channel (such as PDSCH).

[0184] (4) If the end symbol of the PDCCH of the second DCI format is later than the end symbol of the PDCCH of the first DCI format, and the end symbol of the PDCCH of the second DCI format is before the start symbol of the first downlink channel, and the time interval between the end symbol of the PDCCH of the second DCI format and the start symbol of the first downlink channel is greater than or equal to a second duration, the terminal performs the second operation; the second duration can be agreed upon by the protocol or pre-configured, etc., for example, it is equal to M2 symbols, and M2 is a non-negative number.

[0185] Optionally, if the end symbol of the PDCCH of the second DCI format is later than the end symbol of the PDCCH of the first DCI format, and the end symbol of the PDCCH of the second DCI format is before the start symbol of the first downlink channel, and the time interval between the end symbol of the PDCCH of the second DCI format and the start symbol of the first downlink channel is greater than or equal to M2 symbols, the terminal determines to perform the second operation, and M2 is a non-negative number;

[0186] For example Figure 2D as described above, if the first DCI schedules a first downlink channel (such as PDSCH), the second DCI schedules a second uplink channel (such as PUSCH), the end symbol of the second DCI is later than the end symbol of the first DCI, and the end symbol i of the second DCI is before the start symbol j of the first downlink channel (such as PDSCH), and the time interval between the end symbol i of the second DCI and the start symbol j of the first downlink channel (such as PDSCH) is greater than or equal to M2 symbols, then the UE transmits the second uplink channel (such as PUSCH), and abandons receiving / does not receive the first downlink channel (such as PDSCH).

[0187] It should be noted that the reception time of the PDCCH of the DCI format can sometimes also be referred to as: the reception time of the DCI.

[0188] The receiving time of the PDCCH includes but is not limited to: any one of the ending symbol of the PDCCH and the beginning symbol of the PDCCH. Preferably, the receiving time of the PDCCH is the ending symbol of the PDCCH.

[0189] The receiving time of the DCI includes but is not limited to: any one of the ending symbol of the DCI and the beginning symbol of the DCI. Preferably, the receiving time of the DCI is the ending symbol of the DCI.

[0190] Preferably, M1 and M2 are non-negative integers. M1 and M2 can be determined according to the UE processing capability.

[0191] Optionally, the transmission processing method in the embodiments of the present application may further include:

[0192] The terminal determines the transmission direction on the time unit according to the received configuration or indication information;

[0193] The terminal determines the transmission situation of the first downlink channel and the second uplink channel, and / or the overlapping situation of the first downlink channel and the second uplink channel in the time domain according to the transmission direction on the time unit.

[0194] Optionally, before step 11 above, the transmission processing method in the embodiments of the present application may further include:

[0195] The terminal determines the transmission direction on the time unit according to the received configuration or indication information; for example, the configuration or indication information includes but is not limited to: SBFD sub-band configuration, TDD-UL-DL-ConfigDedicated parameter, Slot Format Indicator (SFI), etc.; the time unit includes but is not limited to symbols, symbol sets, time slots, etc. In an alternative embodiment, when the time unit is a symbol, the terminal determines the symbol transmission direction according to the received configuration or indication information;

[0196] The terminal determines whether the first downlink channel and the second uplink channel can be transmitted according to the transmission direction on the time unit. Thereafter, if the first downlink channel and the second uplink channel can be transmitted, when the transmission of the first downlink channel and the transmission of the second uplink channel will overlap in the time domain, the terminal performs a first operation, or a second operation, or does not expect the transmission of the first downlink channel and the transmission of the second uplink channel to overlap in the time domain according to the first information.

[0197] As an alternative embodiment, the transmission processing procedure may include:

[0198] First, according to the uplink and downlink transmission direction determination rules (such as determined based on SBFD sub - band configuration, TDD - UL - DL - ConfigDedicated parameter, Slot Format Indicator (SFI), etc.), determine the symbol transmission direction, and based on the symbol transmission direction, determine whether the uplink channel and the downlink channel can transmit and their actual transmission resources;

[0199] Secondly, for the uplink channel and the downlink channel that can transmit:

[0200] 1> If the uplink channel and the downlink channel overlap in the time domain:

[0201] 2> If the terminal is not provided with a cross - direction priority configuration, or the terminal is provided with a cross - direction priority configuration and the cross - direction priorities of the uplink channel and the downlink channel are the same:

[0202] 31> If the dynamically allocated downlink reception overlaps with the dynamically allocated uplink transmission in the time domain, then determine the conflict resolution rule according to the reception timing of the PDCCH; for example, under certain timing constraint conditions, the transmission scheduled by the DCI in the later - received PDCCH overrides the transmission scheduled by the DCI in the earlier - received PDCCH;

[0203] 32> If the dynamically allocated downlink reception overlaps with the configured uplink grant in the time domain, then the downlink reception overrides the uplink transmission;

[0204] 33> If the configured downlink assignment overlaps with the dynamically allocated uplink transmission in the time domain, then the uplink transmission overrides the downlink reception;

[0205] 34>The terminal does not expect the configured downlink assignment and the configured uplink grant to overlap in the time domain; or, if the configured downlink assignment and the configured uplink grant overlap in the time domain, the terminal adopts the default behavior, such as the downlink overriding the uplink, or vice versa.

[0206] 2>If the terminal is provided with a cross-direction priority configuration and the cross-direction priorities of the uplink channel and the downlink channel are different, determine the conflict resolution rule at least according to the cross-direction priority configurations of the uplink channel and the downlink channel; for example, under certain timing constraint conditions, the high-priority transmission overrides the low-priority transmission.

[0207] In the embodiments of the present application, the first action may be performed according to the authorization or scheduling method of the first downlink channel and the second uplink channel. The above terminal performing the first action according to the first information may include any one of the following:

[0208] If the transmissions of the first downlink channel and the second uplink channel are both configured authorized, the terminal does not expect the transmissions of the first downlink channel and the second uplink channel to overlap in the time domain;

[0209] When the transmissions of the first downlink channel and the second uplink channel will overlap in the time domain, if the transmissions of the first downlink channel and the second uplink channel are both configured authorized, the terminal performs the first operation or the second operation;

[0210] If the transmission of the first downlink channel is scheduled by the fifth DCI format and the transmission of the second uplink channel is scheduled by the sixth DCI format, the terminal does not expect the transmissions of the first downlink channel and the second uplink channel to overlap in the time domain, such as the terminal not expecting the downlink scheduled by DG to conflict with the uplink scheduled by DG.

[0211] Optionally, the terminal not expecting the transmissions of the first downlink channel configured authorized and the second uplink channel configured authorized to overlap in the time domain can be understood as: if the terminal receives the above configuration, that is, the transmissions of the first downlink channel configured authorized and the second uplink channel configured authorized overlap in the time domain, the behavior of the terminal is undefined, and at this time the terminal can choose to receive the first downlink channel, or transmit the second uplink channel, or neither receive the first downlink channel nor transmit the second uplink channel.

[0212] Optionally, when the transmission of the first downlink channel configured for authorization and the transmission of the second uplink channel configured for authorization overlap in the time domain, the terminal performs the first operation or the second operation, which can be understood as: If the terminal receives the above configuration, that is, the transmission of the first downlink channel configured for authorization and the transmission of the second uplink channel configured for authorization overlap in the time domain, then the terminal adopts a certain default behavior. The default behavior can be a certain behavior specified by the protocol or pre-configured to ensure that the base station and the terminal have the same understanding of the relevant behavior. The default behavior can include any one of the following behaviors: the first downlink channel covers the second uplink channel, or the second uplink channel covers the first downlink channel.

[0213] Optionally, for the above solution, the terminal is not configured with a first priority; or, the terminal is configured with a first priority, and the first priority of the first downlink channel is the same as the first priority of the second uplink channel. That is to say, if the terminal is not configured with a first priority, or is configured with a first priority and the first priority of the first downlink channel is the same as the first priority of the second uplink channel, then the terminal performs the first operation or the second operation according to the authorization or scheduling method of the first downlink channel and the second uplink channel, or the timing relationship between the authorization or scheduling of the first downlink channel and the authorization or scheduling of the second uplink channel, or does not expect the transmission of the first downlink channel and the second uplink channel to overlap in the time domain. For the specific method of performing the first operation or the second operation, or not expecting the transmission of the first downlink channel and the second uplink channel to overlap in the time domain according to the authorization or scheduling method of the first downlink channel and the second uplink channel, or the timing relationship between the authorization or scheduling of the first downlink channel and the authorization or scheduling of the second uplink channel, reference can be made to the above description and will not be elaborated here.

[0214] It should be noted that the terminal not being configured with a first priority can also be referred to as: the terminal not being provided with a first priority. The terminal being configured with a first priority can also be referred to as: the terminal being provided with a first priority.

[0215] The first priority of the first downlink channel being the same as the first priority of the second uplink channel can also be referred to as: the cross-direction priority index of the first downlink channel being the same as the cross-direction priority index of the second uplink channel.

[0216] Optionally, performing the first behavior according to the first information can include:

[0217] If the terminal is configured with a first priority and the first priority of the first downlink channel is different from the first priority of the second uplink channel, then the terminal performs any one of the following:

[0218] Perform the first operation, such as determining that the transmission of the first downlink channel covers the transmission of the second uplink channel, at least when the first priority of the first downlink channel is higher than the first priority of the second uplink channel.

[0219] Perform the second operation, such as determining that the transmission of the second uplink channel covers the transmission of the first downlink channel, at least when the first priority of the second uplink channel is higher than the first priority of the first downlink channel.

[0220] It can be understood that the first operation or the second operation is performed according to the configuration of the first priority. The first downlink channel and the second uplink channel can be optionally scheduled by DCI format or configured grant.

[0221] Optionally, the first priority of the first downlink channel can be indicated according to a priority index. The first priority of the second uplink channel can be indicated according to a priority index.

[0222] In one embodiment, a larger priority index can indicate a higher priority. For example, the priority of priority index = 1 > the priority of priority index = 0. At this time, "the priority of the first downlink channel is higher than the priority of the second uplink channel" can also be referred to as "the priority index of the first downlink channel is greater than the priority index of the second uplink channel", or "the first downlink channel has a larger priority index, and the second uplink channel has a smaller priority index".

[0223] In another embodiment, it can also be that a smaller priority index indicates a higher priority. For example, the priority of priority index = 0 > the priority of priority index = 1. At this time, "the priority of the first downlink channel is higher than the priority of the second uplink channel" can also be referred to as "the priority index of the first downlink channel is less than the priority index of the second uplink channel", or "the first downlink channel has a smaller priority index, and the second uplink channel has a larger priority index".

[0224] In the embodiments of the present application, the first priority can be used to determine the priority between the uplink channel and the downlink channel. For example, an inter-direction dedicated priority configuration can be adopted, that is, in addition to the existing uplink channel priority index, a set of inter-direction dedicated priority configurations is added, simply referred to as CD-DPI (cross-direction-dedicate-priority-index). The CD-DPI is only used to determine the priority between different transmission directions. The terminal determines whether to use downlink transmission or uplink transmission according to the size of the CD-DPI.

[0225] Optionally, the DCI format and / or Radio Resource Control (RRC) signaling received by the terminal may include a first priority field and a second priority field. The first priority field is used to indicate the first priority (i.e., the cross-direction priority), and the second priority field is used to indicate the priority of the uplink channel.

[0226] It can be understood that the first priority field is a newly added priority field in this solution. In one embodiment, the DCI format includes a first priority field, and the first priority field is 1 bit; for example: 0 indicates low priority, 1 indicates high priority; or, 0 indicates high priority, 1 indicates low priority. In another embodiment, the RRC signaling includes a first priority field, and the first priority field is an enumerated variable with 2 values; for example, the enumerated variable is p0 and p1, where p0 indicates low priority and p1 indicates high priority; or, p0 indicates high priority and p1 indicates low priority.

[0227] The second priority field is an existing priority field. The base station and the terminal can determine the priorities of multiple uplink channels based on existing rules. The second priority field is, for example, the Priority indicator field in DCI Format 0_1, DCI Format 0_2, DCI Format 1_1, DCI Format 1_2, or the phy-PriorityIndex field in the configured grant PUSCH transmission and SR configuration, etc.

[0228] Optionally, the first priority can be used to determine the priority between at least 2 channels; the at least 2 channels include at least one of the following:

[0229] At least 1 uplink channel and at least 1 downlink channel;

[0230] At least two uplink channels;

[0231] At least two downlink channels.

[0232] For example, an inter-direction joint priority configuration can be adopted, such as extending the existing uplink channel priority index, so that the uplink channel and the downlink channel use the same set of extended priority indexes, which can be simply referred to as CD-JPI (cross-direction-join-priority-index). The CD-JPI can determine the priorities of different channels within the same transmission direction (intra-direction), and can also determine the priorities of different channels between different transmission directions (inter-direction). The terminal jointly determines the priorities between different channels according to the size of the CD-JPI.

[0233] It should be noted that the channel types of the at least two channels are not limited in this embodiment; for example, taking two channels as an example, they can be, but are not limited to: PUSCH and PDSCH, PUCCH and PDSCH, PUSCH and PUCCH, two PUCCHs, two PUSCHs, PDSCH and PDSCH, etc., and will not be enumerated one by one here.

[0234] Optionally, the DCI format and / or RRC signaling received by the terminal may include a third priority field, and the third priority field is used to indicate the priorities between at least two channels, and the at least two channels include at least one of the following: at least one uplink channel and at least one downlink channel; at least two uplink channels; at least two downlink channels.

[0235] Optionally, for the third priority domain, the Priority indicator field in some existing DCI formats can be extended. For example, the Priority indicator field in DCI Format 0_1, DCI Format 0_2, DCI Format 1_1, or DCI Format 1_2 can be extended from 1 bit to 2 bits to enable it to additionally indicate the priority between the uplink channel and the downlink channel; and / or, the phy-PriorityIndex field in some existing RRC signaling can be extended. For example, the phy-PriorityIndex field in the ConfiguredGrantConfig and SchedulingRequestResourceConfig IEs can be extended from 2 enumerated variables {p0, p1} to 3 or more enumerated variables, such as extended to {p0, p1, p2, p3}, to enable it to additionally indicate the priority between the uplink channel and the downlink channel; and / or, a third priority domain can be added to some existing RRC signaling. For example, a third priority domain can be added to the SPS-Config IE to enable it to additionally indicate the priority between the uplink channel and the downlink channel.

[0236] For example, for priority comparison, if the priority of the first channel is greater than the priority of the second channel, it can be determined that the first channel covers the second channel, where: the first channel is a DL channel and the second channel is a UL channel; or, the first channel is a UL channel and the second channel is a UL channel; or, the first channel is a DL channel and the second channel is a DL channel.

[0237] For another example, assume that the priority of the first PDSCH is p0, the priority of the second PDSCH is p2, the priority of the first PUSCH is p1, and the priority of the first PUCCH is p3, and the first PUCCH (p3) > the second PDSCH (p2) > the first PUSCH (p1) > the first PDSCH (p0). Then: if at least 2 channels among the above channels conflict, the higher-priority channel will cover the lower-priority channel in descending order of priority.

[0238] Optionally, the transmission processing method in the embodiments of this application may further include at least one of the following:

[0239] The terminal determines the first priority for receiving the PDSCH scheduled by the seventh DCI format according to the priority indication field in the seventh DCI format, and the first priority for the hybrid automatic repeat request acknowledgment HARQ-ACK feedback corresponding to the reception of the PDSCH.

[0240] The terminal determines the first priority for receiving the SPS PDSCH according to the priority indication field in the semi-persistent scheduling (SPS) configuration cell; and the first priority for HARQ-ACK feedback corresponding to the reception of the SPS PDSCH, and / or the first priority for HARQ-ACK feedback corresponding to the SPS release.

[0241] Optionally, when determining the first priority for receiving the PDSCH scheduled by the seventh DCI format and the first priority for HARQ-ACK feedback corresponding to the reception of the PDSCH according to the priority indication field in the seventh DCI format, the first priority for receiving the PDSCH is equal to the first priority for HARQ-ACK feedback corresponding to the reception of the PDSCH.

[0242] Optionally, when determining the first priority for receiving the SPS PDSCH, the first priority for HARQ-ACK feedback corresponding to the reception of the SPS PDSCH, and / or the first priority for HARQ-ACK feedback corresponding to the SPS release according to the priority indication field in the semi-persistent scheduling (SPS) configuration cell, at least one of the following is satisfied: the first priority for receiving the SPS PDSCH is equal to the first priority for HARQ-ACK feedback corresponding to the reception of the SPS PDSCH; the first priority for receiving the SPS PDSCH is less than or equal to the first priority for HARQ-ACK feedback corresponding to the SPS release.

[0243] Optionally, existing priority fields can be reused. For example, for HARQ-ACK feedback, existing priority fields, such as the Priority indicator field in the DL grant DCI and / or the harq-CodebookID field in the RRC SPS-Config IE, in addition to indicating the priority of the PUCCH / PUSCH carrying the HARQ-ACK feedback, also additionally indicate the priority of the PDSCH channel corresponding to the HARQ-ACK feedback.

[0244] Optionally, the priority indicator field in the seventh DCI format can simultaneously determine the first priority of PDSCH reception scheduled by the seventh DCI format and the first priority of HARQ-ACK feedback corresponding to the PDSCH reception. At this time, the first priority is used to determine the priority between at least two channels. The first priority of the first downlink channel may be: the priority of PDSCH reception indicated by the priority indicator field (such as the Priority indicator field) in the downlink DCI format; the first priority of the second uplink channel is: the priority of HARQ-ACK feedback corresponding to the PDSCH reception (Hybrid Automatic Repeat reQuest Acknowledgement, HARQ-ACK).

[0245] Optionally, the harq-CodebookID field in the priority indicator field of the semi-persistent scheduling (SPS) configuration information element (RRC SPS-Config IE) can simultaneously determine the first priority of SPS PDSCH reception, and the first priority of HARQ-ACK feedback corresponding to the SPS PDSCH reception, and / or the first priority of HARQ-ACK feedback corresponding to SPS release. At this time, the first priority is used to determine the priority between at least two channels. The first priority of the first downlink channel may be: the priority of PDSCH indicated by the harq-CodebookID field in the semi-persistent scheduling (SPS) configuration information element (IE); the first priority of the second uplink channel is: the priority of HARQ-ACK feedback corresponding to the PDSCH.

[0246] In an embodiment of the present application, the current priority indicator fields are fully reused, including the Priority indicator fields in UL grant DCI and DL grant DCI, the phy-PriorityIndex field in the RRC signaling for configuring uplink transmission, and the harq-CodebookID field for configuring downlink SPS transmission. Without increasing the number of bits of the current priority indicator fields, the meanings of some or all of the current priority indicator fields are reinterpreted so that they can simultaneously indicate the priority between UL channels / specific services and the priority between UL channels and DL channels; specifically including:

[0247] - UL grant DCI, such as the 1-bit Priorityindicator field in DCI Format 0_1 and DCI Format 0_2, is used to indicate / determine the priority of the scheduled PUSCH transmission (such as scheduled PUSCH transmissions) or the PUSCH transmission carrying semi-persistent CSI reports (such as PUSCH transmission with semi-persistent CSI report);

[0248] - DL grant DCI, such as the 1-bit Priorityindicator field in DCI Format 1_1 and DCI Format 1_2, is used to indicate / determine the priority of the scheduled PDSCH transmission and the priority of the triggered PUCCH transmission with associated HARQ-ACK information (such as triggered PUCCH transmission with corresponding HARQ-ACK information);

[0249] - The phy-PriorityIndex field in the RRC ConfiguredGrantConfig IE is used to indicate / determine the configured grant PUSCH transmission (such as configured grant PUSCH transmission);

[0250] - The phy-PriorityIndex field in the RRC SchedulingRequestResourceConfig IE is used to indicate / determine the priority of the PUCCH transmission carrying the SR for LBT failure recovery (such as PUCCH transmission with SR for LBT failure recovery);

[0251] - The harq-CodebookID field in the RRC SPS-Config IE is used to indicate / determine the priority of SPS PDSCH reception and the priority of the PUCCH transmission carrying HARQ-ACK feedback for SPS PDSCH reception or release (PUCCH transmission with HARQ-ACK information corresponding to a SPS PDSCH reception or a SPS PDSCH release).

[0252] As shown in Table 1 below, for non-HARQ-ACK feedback, the channels affected by the priority field in this solution are the same as those in the prior art; for HARQ-ACK feedback, in this solution, the priority field (such as the Priorityindicator field in the DL grant DCI and the harq-CodebookID field in the RRC SPS-Config IE, etc.) not only indicates the priority of the PUCCH / PUSCH carrying the HARQ-ACK feedback, but also additionally indicates the priority of the PDSCH channel corresponding to the HARQ-ACK feedback.

[0253] Table 1

[0255] In some embodiments, when the PDSCH channel overlaps with the uplink transmission in the time domain, the terminal can compare the priority of the PDSCH channel and the priority of the uplink transmission, and determine whether to receive the downlink channel, transmit the uplink channel, or consider the uplink-downlink conflict as an undefined behavior.

[0256] Optionally, when the first priority is used to determine the priority between at least two channels, the first priorities of the first downlink channel and the second uplink channel may satisfy at least one of the following:

[0257] The priority of receiving the PDSCH scheduled by the downlink DCI format is equal to the priority of the HARQ-ACK feedback corresponding to the reception of the PDSCH;

[0258] The priority of receiving the SPS PDSCH configured by the higher layer is equal to the priority of the HARQ-ACK feedback corresponding to the reception of the SPS PDSCH;

[0259] The priority of receiving the SPS PDSCH configured by the higher layer is less than or equal to the priority of the HARQ-ACK feedback corresponding to the release of the SPS PDSCH.

[0260] It should be noted that DL transmission includes: DL transmission (from the perspective of the base station) and DL reception (from the perspective of the terminal). UL transmission includes: UL transmission (from the perspective of the terminal) and UL reception (from the perspective of the base station). Therefore, transmission is a superordinate concept of transmission and reception.

[0261] Such as Figure 3AAs shown, without changing the number of bits of the priority field of the existing DCI-scheduled PDSCH reception or SPS PDSCH reception, but reinterpreting the meaning of the priority indicated by it, so that it can simultaneously indicate the priority of HARQ-ACK feedback (UL channel) and the priority of the PDSCH channel (DL channel) corresponding to the HARQ-ACK feedback. In particular, the priority of the DCI-scheduled PDSCH reception or SPS PDSCH reception is equal to the priority of the HARQ-ACK feedback corresponding to the PDSCH reception, that is, the DCI-scheduled PDSCH reception or SPS PDSCH reception and the uplink channel carrying the corresponding HARQ-ACK feedback have the same priority n.

[0262] Based on the above method, the first 2 combinations in Table 2 below can be supported, but the last 2 combinations cannot be supported. However, as shown in the remarks, the last 2 combinations are abnormal situations and do not need to be supported.

[0263] Table 2

[0264]

[0265]

[0266] Considering that the uplink channel carrying the HARQ-ACK feedback of SPS PDSCH release is more important than the ordinary SPS PDSCH reception, its priority can be set higher, that is, the first priority of SPS PDSCH reception is less than or equal to the first priority of the HARQ-ACK feedback corresponding to the SPS release.

[0267] Optionally, determine the first priority of the HARQ-ACK feedback of SPS PDSCH release according to protocol agreement or higher-layer configuration. For example, through protocol agreement or higher-layer configuration, determine that the priority of the HARQ-ACK feedback of SPS PDSCH release is m, and the determination of priority m has nothing to do with the harq-CodebookID field in the RRC SPS-Config IE. m is generally a higher priority.

[0268] Optionally, determine the first priority of the HARQ-ACK feedback of SPS PDSCH release according to the priority indication in the harq-CodebookID field and protocol agreement or higher-layer configuration. For example, the first priority = max{harq-CodebookID, m}, where the priority m is determined by protocol agreement or higher-layer configuration.

[0269] Optionally, according to the priority indication in the harq-CodebookID field, look up a table to determine at least one of the first priority for SPS PDSCH reception, the first priority for HARQ-ACK feedback corresponding to SPS PDSCH reception, and the first priority for HARQ-ACK feedback for SPS PDSCH release. Table 3 gives an example of a look-up table.

[0270] Table 3

[0271]

[0272] As Figure 3B shown, the priority of the uplink channel carrying the HARQ-ACK feedback for SPS PDSCH release can be set to m, and the priorities of SPS PDSCH reception and the corresponding HARQ-ACK feedback can be set to n, and m≥n.

[0273] Optionally, when performing the first operation, such as determining that the transmission of the first downlink channel covers the transmission of the second uplink channel, the transmission processing method in this embodiment may further include:

[0274] The terminal transmits the cancelled service on the second uplink channel according to the next transmission opportunity or the base station scheduling to ensure the normal transmission of the service.

[0275] For example, if the downlink transmission covers the uplink transmission, the terminal can actively transmit the cancelled uplink service at the subsequent CG PUSCH transmission opportunity; or, since the base station knows that this uplink transmission is cancelled, the base station can then schedule the terminal for uplink transmission through UL grant DCI; the terminal transmits the cancelled uplink service on the uplink resources scheduled by the base station.

[0276] Optionally, when performing the second operation, such as determining that the transmission of the second uplink channel covers the transmission of the first downlink channel, the transmission processing method in this embodiment may further include:

[0277] The terminal receives the cancelled service on the first downlink channel according to the base station scheduling or the pre-configured transmission opportunity.

[0278] For example, if the uplink transmission covers the downlink transmission, the base station can transmit the cancelled downlink service through subsequent downlink DCI scheduling or SPS PDSCH transmission opportunity; the terminal can receive the cancelled downlink service based on the DCI scheduling indication of the base station or the pre-configured SPS PDSCH transmission opportunity.

[0279] Please refer to Figure 4 ,Figure 4 It is a flowchart of a transmission processing method provided by an embodiment of the present application. This method is applied to a base station, such as Figure 4 shown, and the method includes the following steps:

[0280] Step 41: The base station performs a second behavior according to the first information; the second behavior includes at least one of the following: when the transmission of the first downlink channel of the terminal and the transmission of the second uplink channel will overlap in the time domain, determining that the terminal performs a first operation or a second operation; determining to avoid scheduling or configuring the transmission of the first downlink channel of the terminal and the transmission of the second uplink channel to overlap in the time domain.

[0281] In an embodiment of the present application, the first information includes at least one of the following: the configuration of the first priority of the first downlink channel and the second uplink channel, the authorization or scheduling method of the first downlink channel and the second uplink channel, and the timing relationship between the authorization or scheduling of the first downlink channel and the authorization or scheduling of the second uplink channel.

[0286] Determining that the transmission of the second uplink channel covers the transmission of the first downlink channel;

[0287] Transmitting the second uplink channel, and / or, abandoning the reception or not receiving the first downlink channel.

[0288] The situation where the transmission of the first downlink channel covers the transmission of the second uplink channel can also be described as: the first downlink channel covers the second uplink channel; or described as: receiving the first downlink channel, and / or, abandoning (cancel) the transmission / not transmitting the second uplink channel. Among them, abandoning (cancel) the transmission of the second uplink channel can also be referred to as: the second uplink channel shall not be transmitted.

[0289] The situation where the transmission of the second uplink channel covers the transmission of the first downlink channel can also be described as: the second uplink channel covers the first downlink channel; or described as: abandoning (cancel) the reception / not receiving the first downlink channel, and / or, transmitting the second uplink channel. Among them, abandoning (cancel) the reception of the first downlink channel can also be referred to as: the first downlink channel shall not be received.

[0290] Therefore, through the solution in this application, it can be determined how to handle the uplink and downlink transmission conflicts of the terminal, such as solving the transmission conflict problem between different transmission directions (inter-direction) in a full-duplex network, and improving the transmission reliability.

[0291] Optionally, the first priority may also be referred to as the cross-direction priority, and can be at least used to determine the priority between different transmission directions.

[0296] If the first downlink channel is scheduled by the first DCI format and the second uplink channel is scheduled by the second DCI format, the base station determines whether the terminal performs the first operation or the second operation according to the time sequence relationship between the reception time of the PDCCH of the first DCI format and the reception time of the PDCCH of the second DCI format;

[0297] If the first downlink channel is scheduled by a third DCI format and the second uplink channel is configured with grant, the base station determines that the terminal performs the first operation;

[0302] If the reception time of the PDCCH of the second DCI format is later than the reception time of the PDCCH of the first DCI format, the base station determines that the terminal performs the second operation;

[0304] Optionally, performing the second behavior according to the first information further includes any one of the following:

[0305] If the transmissions of the first downlink channel and the second uplink channel are both configured with grant, the base station, through scheduling or configuration, avoids the transmissions of the first downlink channel and the second uplink channel overlapping in the time domain;

[0306] When the transmission of the first downlink channel and the transmission of the second uplink channel will overlap in the time domain, if both the transmission of the first downlink channel and the transmission of the second uplink channel are configured grants, the base station determines that the terminal performs the first operation or the second operation;

[0307] If the transmission of the first downlink channel is scheduled by the fifth DCI format and the transmission of the second uplink channel is scheduled by the sixth DCI format, the base station avoids the transmission of the first downlink channel and the transmission of the second uplink channel from overlapping in the time domain through scheduling or configuration.

[0308] Optionally, for the above solution, the terminal is not configured with a first priority; or, the terminal is configured with a first priority, and the first priority of the first downlink channel is the same as the first priority of the second uplink channel.

[0309] Optionally, the above determination that the terminal performs the first operation or the second operation includes:

[0322] 1) If the UE is provided with a cross-direction priority configuration and the priority associated with the second uplink channel does not reach the highest priority, then the base station can indicate through DCI that the first downlink channel is associated with a higher priority, so that the transmission on the first downlink channel covers the transmission on the second uplink channel;

[0323] 2) If the UE is not provided with a cross-direction priority configuration, then the base station can first use the second DCI to schedule the second uplink channel and then use the first DCI to schedule the first downlink channel, that is, according to the Figure 5A shown specific timing relationship, so that the transmission on the first downlink channel covers the transmission on the second uplink channel;
