In an SBFD network, base stations are capable of simultaneous transmission and reception, but terminals do not. If uplink and downlink transmission resources overlap in the time domain, the terminal must select a specific transmission direction.

[0159] Therefore, as an embodiment, the terminal does not expect the transmission of the first downlink channel and the transmission of the second uplink channel to overlap in the time domain, which can also be described in any of the following forms:

[0160] 1) The terminal expects that the transmission of the first downlink channel and the transmission of the second uplink channel do not overlap in the time domain;

[0161] 2) The behavior of the terminal when the transmission on the first downlink channel and the transmission on the second uplink channel overlap in the time domain is undefined;

[0162] 3) When the transmission of the first downlink channel and the transmission of the second uplink channel overlap in the time domain, no constraints are imposed on the terminal behavior;

[0163] 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 instruction of the network;

[0164] 5) It is recommended that the base station not configure / instruct that the transmission of the first downlink channel and the transmission of the second uplink channel overlap in the time domain.

[0165] The undefined terminal behavior means that when a terminal receives an unexpected network configuration / indication, its behavior is undefined. In this case, the terminal may adopt any behavior. For example, in this solution, when a terminal receives an unexpected network configuration / indication, it may choose to receive the first downlink channel, transmit the second uplink channel, or neither receive nor transmit the first downlink channel.

[0166] Optionally, the first behavior may be performed based on 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 terminal performing the first behavior based on the first information may include any of the following:

[0167] When transmission of the first downlink channel and 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 a sequence of reception times of a PDCCH in the first DCI format and a PDCCH in the second DCI format;

[0168] When transmission of the first downlink channel and 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;

[0169] When transmission of the first downlink channel and 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.

[0170] It should be noted that the first downlink channel is scheduled by the first DCI format, which can also be called: the first downlink channel is dynamically granted DG, the first downlink channel is dynamically allocated downlink reception, etc.

[0171] The second uplink channel is scheduled by the second DCI format, which may also be referred to as: the second uplink channel is dynamically granted DG, the second uplink channel is dynamically allocated uplink transmission, etc.

[0172] The second uplink channel is configured with a grant (configured grant), which may also be referred to as: the second uplink channel is a configured uplink grant (configured uplink grant), etc.

[0173] The first downlink channel is configured with a grant, which may also be referred to as: the first downlink channel is configured with a downlink assignment, the first downlink channel is semi-persistent scheduling (SPS), and the like.

[0174] The DCI format may be referred to as DCI for short.

[0175] The reception time of the PDCCH of the first / second DCI format may also be referred to as the reception time of the DCI corresponding to the first / second DCI format.

[0176] The "sequential relationship between the reception time of the PDCCH in the first DCI format and the reception time of the PDCCH in the second DCI format" can also be referred to as: the timing relationship between the reception time of the PDCCH in the first DCI format and the reception time of the PDCCH in the second DCI format.

[0177] The performing of the first operation or the second operation according to the chronological relationship between the reception moments of the PDCCH of the first DCI format and the reception moments of the PDCCH of the second DCI format can also be expressed as: performing the first operation or the second operation according to the chronological relationship between the reception moments of the PDCCH of the first DCI format and the reception moments of the PDCCH of the second DCI format; or can be expressed as: performing the first operation or the second operation according to the timing relationship between the reception moments of the PDCCH of the first DCI format and the reception moments of the PDCCH of the second DCI format.

[0178] Optionally, the performing of the first operation or the second operation according to the sequence of the reception time of the PDCCH in the first DCI format and the reception time of the PDCCH in the second DCI format may include at least one of the following:

[0179] (1) If the reception time of the PDCCH in the first DCI format is later than the reception time of the PDCCH in the second DCI format, the terminal performs the first operation;

[0180] For example, as shown in Figure 2A, 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, the UE receives the first downlink channel (such as PDSCH) and gives up transmitting / does not transmit the second uplink channel (such as PUSCH).

[0181] (2) If the end symbol of the PDCCH in the first DCI format is later than the end symbol of the PDCCH in the second DCI format, and the end symbol of the PDCCH in 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 in the first DCI format and the start symbol of the second uplink channel is greater than or equal to a first duration, the terminal performs the first operation; the first duration can be agreed upon or pre-configured, for example, equal to M1 symbols, where M1 is a non-negative number;

[0182] Optionally, if the end symbol of the PDCCH in the first DCI format is later than the end symbol of the PDCCH in the second DCI format, and the end symbol of the PDCCH in 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 in 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, and M1 is a non-negative number;

[0183] For example, as shown in Figure 2B, 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 gives up transmitting / does not transmit the second uplink channel (such as PUSCH).

[0184] (3) If the reception time of the PDCCH in the second DCI format is later than the reception time of the PDCCH in the first DCI format, the terminal performs the second operation;

[0185] For example, as shown in Figure 2C, 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 second DCI is later than the reception time of the first DCI, the UE transmits the second uplink channel (such as PUSCH) and gives up receiving / not receiving the first downlink channel (such as PDSCH).

[0186] (4) If the end symbol of the PDCCH in the second DCI format is later than the end symbol of the PDCCH in the first DCI format, and the end symbol of the PDCCH in 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 in 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 or pre-configured, for example, equal to M2 symbols, and M2 is a non-negative number.

[0187] Optionally, if the end symbol of the PDCCH in the second DCI format is later than the end symbol of the PDCCH in the first DCI format, and the end symbol of the PDCCH in 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 in 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;

[0188] For example, as shown in Figure 2D, 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 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 gives up receiving / not receiving the first downlink channel (such as PDSCH).

[0189] It should be noted that the reception time of the PDCCH in the DCI format may sometimes also be referred to as the reception time of the DCI.

[0190] 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.

[0191] 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.

[0192] Preferably, M1 and M2 are non-negative integers. M1 and M2 may be determined according to the terminal processing capability (UE processing capability).

[0193] Optionally, the transmission processing method in the embodiment of the present disclosure may further include:

[0194] The terminal determines the transmission direction on the time unit according to the received configuration or instruction information;

[0195] The terminal determines, according to the transmission direction in the time unit, transmission conditions of the first downlink channel and the second uplink channel, and / or an overlap condition of the first downlink channel and the second uplink channel in the time domain.

[0196] Optionally, before step 11 above, the transmission processing method in the embodiment of the present disclosure may further include:

[0197] The terminal determines the transmission direction on the time unit based on the received configuration or indication information; for example, the configuration or indication information includes but is not limited to: SBFD subband configuration, TDD-UL-DL-ConfigDedicated parameter, slot format indicator (SFI), etc.; the time unit includes but is not limited to a symbol, a symbol set, a time slot, etc. In an optional embodiment, the time unit is a symbol, and the terminal determines the symbol transmission direction based on the received configuration or indication information;

[0198] The terminal determines, based on the transmission direction in the time unit, whether the first downlink channel and the second uplink channel can be transmitted. Thereafter, if the first downlink channel and the second uplink channel can be transmitted, when transmission of the first downlink channel and transmission of the second uplink channel will overlap in the time domain, the terminal performs a first operation or a second operation based on the first information, or does not expect transmission of the first downlink channel and transmission of the second uplink channel to overlap in the time domain.

[0199] As an optional embodiment, the transmission process may include:

[0200] First, the symbol transmission direction is determined based on the uplink and downlink transmission direction determination rules (e.g., based on the SBFD subband configuration, TDD-UL-DL-ConfigDedicated parameters, Slot Format Indicator (SFI)), and based on the symbol transmission direction, whether the uplink and downlink channels can be transmitted and their actual transmission resources are determined.

[0201] Secondly, for the uplink and downlink channels that can be transmitted:

[0202] 1> If the uplink channel and downlink channel overlap in the time domain:

[0203] 2> If the terminal is not provided with cross-direction priority configuration, or the terminal is provided with cross-direction priority configuration and the cross-direction priorities of the uplink channel and the downlink channel are the same:

[0204] 31> If dynamically allocated downlink reception and dynamically allocated uplink transmission overlap in the time domain, a conflict resolution rule is determined based on the PDCCH reception timing. For example, if certain timing constraints are met, the DCI-scheduled transmission in the later-received PDCCH overrides the DCI-scheduled transmission in the earlier-received PDCCH.

[0205] 32> If the dynamically allocated downlink reception and the configured uplink grant overlap in the time domain, the downlink reception overrides the uplink transmission;

[0206] 33> If the configured downlink assignment and the dynamically allocated uplink transmission overlap in the time domain, the uplink transmission overrides the downlink reception;

[0207] 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 that the downlink overrides the uplink, or vice versa.

[0208] 2> If the terminal is provided with cross-directional priority configuration, and the cross-directional priorities of the uplink channel and the downlink channel are different, the conflict resolution rule is determined based on at least the cross-directional priority configuration of the uplink channel and the downlink channel; for example, under certain timing constraints, high-priority transmission overrides low-priority transmission.

[0209] In the embodiment of the present disclosure, the first action may be performed according to the authorization or scheduling mode of the first downlink channel and the second uplink channel. The terminal may perform the first action according to the first information, including any of the following:

[0210] If both transmission on the first downlink channel and transmission on the second uplink channel are configured as authorized, the terminal does not expect transmission on the first downlink channel and transmission on the second uplink channel to overlap in the time domain;

[0211] When transmission of the first downlink channel and transmission of the second uplink channel will overlap in the time domain, if both transmission of the first downlink channel and transmission of the second uplink channel are configured as authorized, the terminal performs the first operation or the second operation;

[0212] 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 transmission of the first downlink channel and the transmission of the second uplink channel to overlap in the time domain, such as the terminal does not expect the DG-scheduled downlink to conflict with the DG-scheduled uplink.

[0213] Optionally, the terminal does not expect the transmission of the first downlink channel configured for authorization and the transmission of the second uplink channel configured for authorization to overlap in the time domain. It can be understood that: 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 behavior of the terminal is undefined. 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.

[0214] 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 a consistent 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, and the second uplink channel covers the first downlink channel.

[0215] Optionally, for the above solution, the terminal is not configured with the first priority; or the terminal is configured with the 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, if the terminal is not configured with the first priority, or is configured with the 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 transmission of the second uplink channel to overlap in the time domain. As for how to perform 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 not expect the transmission of the first downlink channel and the transmission of the second uplink channel to overlap in the time domain, please refer to the above description and will not be repeated here.

[0216] It should be noted that the terminal not being configured with the first priority may also be referred to as the terminal not being provided with the first priority. The terminal being configured with the first priority may also be referred to as the terminal being provided with the first priority.

[0217] The first priority of the first downlink channel is the same as the first priority of the second uplink channel, which can also be called: the cross-directional priority index (index) of the first downlink channel is the same as the cross-directional priority index (index) of the second uplink channel.

[0218] Optionally, executing the first action according to the first information may include:

[0219] If the terminal is configured with the first priority, and the first priority of the first downlink channel is different from the first priority of the second uplink channel, the terminal performs any one of the following:

[0220] At least when the first priority of the first downlink channel is higher than the first priority of the second uplink channel, performing the first operation, such as determining that transmission of the first downlink channel covers transmission of the second uplink channel;

[0221] At least when the first priority of the second uplink channel is higher than the first priority of the first downlink channel, the second operation is performed, such as determining that transmission of the second uplink channel covers transmission of the first downlink channel.

[0222] It is understandable 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 scheduled by a DCI format or configured with a grant.

[0223] Optionally, the first priority of the first downlink channel may be indicated by a priority index. The first priority of the second uplink channel may be indicated by a priority index.

[0224] In one embodiment, a larger priority index may indicate a higher priority. For example, priority index = 1 > priority index = 0. In this case, "the priority of the first downlink channel is higher than the priority of the second uplink channel" may 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 as "the first downlink channel has a larger priority index, and the second uplink channel has a smaller priority index."

[0225] In another embodiment, a smaller priority index may indicate a higher priority. For example, priority index = 0 > priority index = 1. In this case, "the priority of the first downlink channel is higher than the priority of the second uplink channel" may also be referred to as "the priority index of the first downlink channel is smaller than the priority index of the second uplink channel," or as "the first downlink channel has a smaller priority index, and the second uplink channel has a larger priority index."

[0226] In the disclosed embodiment, the first priority level can be used to determine the priority between an uplink channel and a downlink channel. For example, a cross-direction dedicated priority configuration can be used. That is, in addition to the existing uplink channel priority index, a new cross-direction dedicated priority configuration, referred to as CD-DPI (cross-direction-dedicated-priority-index), can be added. The CD-DPI is only used to determine the priority between different transmission directions. The terminal determines whether to use downlink or uplink transmission based on the size of the CD-DPI.

[0227] 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, wherein the first priority field is used to indicate a first priority (i.e., cross-directional priority), and the second priority field is used to indicate the priority of the uplink channel.

[0228] It is understandable 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 enumeration variable with 2 values; for example, the enumeration variables are p0 and p1, where p0 indicates low priority and p1 indicates high priority; or, p0 indicates high priority and p1 indicates low priority.

[0229] The second priority field is an existing priority field. The base station and terminal can use the second priority field to determine multiple uplink channel priorities based on existing rules. The second priority field can be, for example, the Priority indicator field in DCI Format 0_1, DCI Format 0_2, DCI Format 1_1, or DCI Format 1_2, or the phy-PriorityIndex field in the configured grant PUSCH transmission and SR configuration.

[0230] Optionally, the first priority may be used to determine a priority between at least two channels; the at least two channels include at least one of the following:

[0231] At least one uplink channel and at least one downlink channel;

[0232] At least 2 uplink channels;

[0233] At least 2 downlink channels.

[0234] For example, a cross-direction joint priority configuration can be used, such as expanding the existing uplink channel priority index so that both the uplink and downlink channels use the same extended priority index, referred to as a cross-direction-join-priority-index (CD-JPI). The CD-JPI can determine the priorities of different channels within the same transmission direction (intra-direction) as well as between different transmission directions (inter-direction). The terminal jointly determines the priorities of different channels based on the size of the CD-JPI.

[0235] It should be noted that this embodiment does not limit the channel type of the at least two channels; for example, taking two channels as an example, the options are but not limited to: PUSCH and PDSCH, PUCCH and PDSCH, PUSCH and PUCCH, 2 PUCCHs, 2 PUSCHs, PDSCH and PDSCH, etc., which are not listed one by one here.

[0236] 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 priority between at least 2 channels, and the at least 2 channels include at least one of the following: at least 1 uplink channel and at least 1 downlink channel; at least 2 uplink channels; at least 2 downlink channels.

[0237] Optionally, for the third priority field, the Priority indicator field in some existing DCI formats can be extended, such as extending the Priority indicator field in DCI Format 0_1, DCI Format 0_2, DCI Format 1_1 or DCI Format 1_2 from 1 bit to 2 bits, so that it can additionally indicate the priority between the uplink channel and the downlink channel; and / or, the phy-PriorityIndex field in some existing RRC signaling is extended, such as extending the phy-PriorityIndex field of ConfiguredGrantConfig and SchedulingRequestResourceConfig IE from 2 enumeration variables {p0, p1} to 3 or more enumeration variables, such as extending to {p0, p1, p2, p3}, so that it can additionally indicate the priority between the uplink channel and the downlink channel; and / or, adding a third priority field in some existing RRC signaling, such as adding a third priority field in SPS-Config IE, so that it can additionally indicate the priority between the uplink channel and the downlink channel.

[0238] 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 downlink (DL) channel and the second channel is an uplink (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.

[0239] For another example, assuming 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, 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 two of the above channels conflict, the higher-priority channel will cover the lower-priority channel in order of priority from high to low.

[0240] Optionally, the transmission processing method in the embodiment of the present disclosure may further include at least one of the following:

[0241] The terminal determines, according to the priority indication field in the seventh DCI format, a first priority for receiving a PDSCH scheduled by the seventh DCI format and a first priority for receiving a corresponding hybrid automatic repeat request acknowledgement HARQ-ACK feedback by the PDSCH;

[0242] The terminal determines the first priority of SPS PDSCH reception according to the priority indication field in the semi-persistent scheduling SPS configuration information element; 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 the SPS release.

[0243] Optionally, when the first priority of PDSCH reception scheduled by the seventh DCI format and the first priority of the PDSCH reception corresponding HARQ-ACK feedback are determined according to the priority indication field in the seventh DCI format, the first priority of the PDSCH reception is equal to the first priority of the PDSCH reception corresponding HARQ-ACK feedback.

[0244] Optionally, when determining the first priority of SPS PDSCH reception, the first priority of HARQ-ACK feedback corresponding to the SPS PDSCH reception, and / or the first priority of HARQ-ACK feedback corresponding to the SPS release based on the priority indication field in the semi-persistent scheduling SPS configuration information element, at least one of the following items is satisfied: the first priority of SPS PDSCH reception is equal to the first priority of HARQ-ACK feedback corresponding to the SPS PDSCH reception; the first priority of SPS PDSCH reception is less than or equal to the first priority of HARQ-ACK feedback corresponding to the SPS release.

[0245] Optionally, an existing priority field can be reused. For example, for HARQ-ACK feedback, the existing priority field, such as the Priority indicator field in the downlink grant (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 indicates the priority of the PDSCH channel corresponding to the HARQ-ACK feedback.

[0246] Optionally, the priority indicator field Priority indicator of the seventh DCI format can simultaneously determine the first priority of the PDSCH reception scheduled by the seventh DCI format and the first priority of the PDSCH reception corresponding to the HARQ-ACK feedback. 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 can be: the priority of the 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 the PDSCH reception corresponding to the hybrid automatic repeat request acknowledgment (Hybrid Automatic Repeat reQuest Acknowledgement, HARQ-ACK) feedback.

[0247] Optionally, the priority indication field harq-CodebookID field in the semi-persistent scheduling SPS configuration information element RRC SPS-Config IE can simultaneously determine the first priority of SPS PDSCH reception, as well as the first priority of the HARQ-ACK feedback corresponding to the SPS PDSCH reception, and / or the first priority of the HARQ-ACK feedback corresponding to the 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 can be: the priority of the 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 the HARQ-ACK feedback corresponding to the PDSCH.

[0248] In one embodiment of the present disclosure, the current priority indicator field is fully reused, including the Priority indicator field in UL grant DCI and DL grant DCI, the phy-PriorityIndex field in the RRC signaling used to configure uplink transmission, and the harq-CodebookID field used to configure downlink SPS transmission. Without increasing the number of bits in the current priority indicator field, the meaning of part or all of the current priority indicator field is reinterpreted to enable it to simultaneously indicate the priority between UL channels / specific services, as well as the priority between UL channels and DL channels. Specifically, the following steps are performed:

[0249] -UL grant DCI, such as the 1-bit Priority indicator field in DCI Format 0_1 ​​and DCI Format 0_2, used to indicate / determine the priority of scheduled PUSCH transmissions (e.g., scheduled PUSCH transmissions) or PUSCH transmissions carrying semi-persistent CSI reports (e.g., PUSCH transmissions with semi-persistent CSI reports);

[0250] -DL grant DCI, such as the 1-bit Priority indicator field in DCI Format 1_1 and DCI Format 1_2, is used to indicate / determine the priority of scheduled PDSCH transmissions and the priority of triggered PUCCH transmissions with corresponding HARQ-ACK information;

[0251] -The phy-PriorityIndex field in the RRC ConfiguredGrantConfig IE is used to indicate / determine the configured granted PUSCH transmission (e.g., configured grant PUSCH transmission);

[0252] -The phy-PriorityIndex field in the RRC SchedulingRequestResourceConfig IE is used to indicate / determine the priority of the PUCCH transmission carrying the SR for Listen-Before-Talk (LBT) failure recovery (e.g., PUCCH transmission with SR for LBT failure recovery);

[0253] -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 PUCCH transmission with HARQ-ACK information corresponding to a SPS PDSCH reception or a SPS PDSCH release.

[0254] As shown in Table 1 below, for non-HARQ-ACK feedback, the channels affected by the priority field in this scheme are the same as those in the prior art; for HARQ-ACK feedback, the priority field in this scheme (such as the Priority indicator field in the DL grant DCI and the harq-CodebookID field in the RRC SPS-Config IE, etc.) In addition to indicating the priority of the PUCCH / PUSCH carrying the HARQ-ACK feedback, it also additionally indicates the priority of the PDSCH channel corresponding to the HARQ-ACK feedback.

[0255] Table 1

[0256] 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 interpret the uplink-downlink conflict as undefined behavior.

[0257] 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:

[0258] The priority of receiving a PDSCH scheduled in a downlink DCI format is equal to the priority of receiving the corresponding HARQ-ACK feedback for the PDSCH;

[0259] The priority of the SPS PDSCH reception configured by the higher layer is equal to the priority of the HARQ-ACK feedback corresponding to the SPS PDSCH reception;

[0260] The priority of SPS PDSCH reception configured by the higher layer is less than or equal to the priority of HARQ-ACK feedback corresponding to SPS PDSCH release.

[0261] It should be noted that DL transmission includes DL transmission (from the base station's perspective) and DL reception (from the terminal's perspective). UL transmission includes UL transmission (from the terminal's perspective) and UL reception (from the base station's perspective). Therefore, transmission is a higher-level concept than transmission and reception.

[0262] As shown in Figure 3A, the number of bits of the priority field of the existing DCI-scheduled PDSCH reception (reception) or SPS PDSCH reception is not changed, but the meaning of the priority indicated therein is reinterpreted so that it can simultaneously indicate the priority of the 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 (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 (reception) or SPS PDSCH reception and the uplink channel carrying the corresponding HARQ-ACK feedback have the same priority n.

[0263] Based on the above method, the first two combinations in Table 2 below are supported, but the last two combinations are not supported. However, as noted in the notes, the last two combinations are abnormal and do not need to be supported.

[0264] Table 2

[0265] Considering that the uplink channel carrying the HARQ-ACK feedback of the SPS PDSCH release is more important than the ordinary SPS PDSCH reception, its priority can be set higher, that is, the first priority of the SPS PDSCH reception is less than or equal to the first priority of the HARQ-ACK feedback corresponding to the SPS release.

[0266] Optionally, the first priority of the HARQ-ACK feedback for the SPS PDSCH release is determined according to protocol agreement or high-level configuration. For example, the priority of the HARQ-ACK feedback for the SPS PDSCH release is determined to be m according to protocol agreement or high-level configuration. The determination of priority m is independent of the harq-CodebookID field in the RRC SPS-Config IE. m is generally a higher priority.

[0267] Optionally, a first priority level of HARQ-ACK feedback for the SPS PDSCH release is determined based on the priority indication in the harq-CodebookID field and protocol agreement or high-level configuration. For example, the first priority level = max{harq-CodebookID, m}, where priority level m is determined by protocol agreement or high-level configuration.

[0268] Optionally, based on the priority indication in the harq-CodebookID field, a table lookup is performed 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 shows an embodiment of a lookup table.

[0269] Table 3

[0270] As shown in FIG3B , the priority of the uplink channel carrying the HARQ-ACK feedback of the SPS PDSCH release can be set to m, and the priority of the SPS PDSCH reception and the corresponding HARQ-ACK feedback can be set to n, and m≥n.

[0271] Optionally, when performing the first operation, such as determining that transmission on the first downlink channel covers transmission on the second uplink channel, the transmission processing method in this embodiment may further include:

[0272] The terminal transmits the cancelled service on the second uplink channel according to the next transmission opportunity or base station scheduling to ensure normal transmission of the service.

[0273] For example, if the downlink transmission covers the uplink transmission, the terminal can actively transmit the canceled uplink service in the subsequent CG PUSCH transmission opportunity; or, the base station knows that the uplink transmission is canceled, so the base station can schedule the terminal for uplink transmission through UL grant DCI; the terminal transmits the canceled uplink service on the uplink resources scheduled by the base station.

[0274] 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:

[0275] The terminal receives the cancelled service on the first downlink channel according to a transmission opportunity scheduled or pre-configured by the base station.

[0276] For example, if uplink transmission covers downlink transmission, the base station can transmit the canceled downlink service through subsequent downlink DCI scheduling or SPS PDSCH transmission opportunity; the terminal can receive the canceled downlink service based on the DCI scheduling indication of the base station or the pre-configured SPS PDSCH transmission opportunity.

[0277] Please refer to FIG4 , which is a flowchart of a transmission processing method provided by an embodiment of the present disclosure. The method is applied to a base station. As shown in FIG4 , the method includes the following steps:

[0285] The second uplink channel is transmitted, and / or the first downlink channel is abandoned or not received.

[0286] The transmission of the first downlink channel overriding the transmission of the second uplink channel can also be described as: the first downlink channel overriding the second uplink channel; or as: receiving the first downlink channel and / or canceling / not transmitting the second uplink channel. Canceling the transmission of the second uplink channel can also be referred to as: the second uplink channel shall not be transmitted.

[0295] If the first downlink channel is scheduled by the third DCI format and the second uplink channel is configured with authorization, the base station determines that the terminal performs the first operation;

[0300] If the reception time of the PDCCH in the second DCI format is later than the reception time of the PDCCH in the first DCI format, the base station determines that the terminal performs the second operation;

[0302] Optionally, performing the second action according to the first information further includes any of the following:

[0303] If both transmission of the first downlink channel and transmission of the second uplink channel are configured as authorized, the base station avoids, through scheduling or configuration, transmission of the first downlink channel and transmission of the second uplink channel from overlapping in the time domain;

[0304] When transmission of the first downlink channel and transmission of the second uplink channel will overlap in the time domain, if both transmission of the first downlink channel and transmission of the second uplink channel are configured as authorized, the base station determines that the terminal performs the first operation or the second operation;

For this purpose, the base station may adopt any of the following methods:
