Description

Technical Field

[0001] This application relates to the field of communication technology, specifically to a communication processing method, apparatus, device, and medium. Background Technology

[0002] In a Sub-Band Full Duplex (SBFD) system, the base station can simultaneously transmit and receive uplink and downlink signals using SBFD symbols. Traditionally, if the repetitive transmission of the Dynamic Physical Downlink Shared Channel (PDSCH) and the Configured Grant (CG) Physical Uplink Shared Channel (PUSCH) overlap in the time domain and meet timing requirements, the terminal will receive the Dynamic PDSCH but not transmit the CG PUSCH. However, considering that if the CG PUSCH is a high-priority transmission, continuous repetitive PDSCH transmission would occupy continuous time resources, making it impossible to transmit the CG PUSCH with low latency. This is detrimental to Ultra-Reliable Low-Latency Communications (URLLC) services. (See [link to relevant documentation]). Figure 1 Therefore, in a sub-band duplex system, when the high-priority CG PUSCH and the low-priority PDSCH overlap in the time domain, the terminal can send PUSCH but not receive PDSCH. Thus, determining the time slot in which the terminal actually receives the overlapping PDSCH is an urgent problem to be solved. Summary of the Invention

[0003] This application provides a communication processing method, apparatus, device, and medium to solve the problem of how to determine the time slots in which a terminal actually receives repeated PDSCH.

[0004] Firstly, a communication processing method is provided, applied to a terminal, including:

[0005] The time slot for receiving PDSCH repetitions is determined based on one or more of the following: PDSCH priority, PUSCH priority, PDSCH symbol, PUSCH symbol, and PUSCH type.

[0006] Optionally, the time slot for receiving PDSCH repetitions is determined based on one or more of the following: PDSCH priority, PUSCH priority, PDSCH symbol, PUSCH symbol, and PUSCH type, including:

[0007] If at least one symbol of the PUSCH in the first target time slot overlaps with at least one symbol of the PDSCH, the terminal determines that the first target time slot is a time slot for receiving repeated PDSCH based on one or more of the following: PDSCH priority, PUSCH priority, and PUSCH type; or determines that the first target time slot is not a time slot for receiving repeated PDSCH.

[0008] Optionally, determining that the first target time slot is not a time slot for receiving repeated PDSCHs based on one or more of the following: PDSCH priority, PUSCH priority, and PUSCH type, including:

[0009] When the first condition is met, it is determined that the first target time slot is not a time slot for receiving repeated PDSCH.

[0010] The first condition includes at least one of the following:

[0011] The PDSCH has a high priority, the PUSCH has a high priority, and the DCI that schedules the PDSCH also indicates that the PDSCH should not be received.

[0012] The PDSCH has a low priority, and the PUSCH has a high priority.

[0013] The PDSCH has a low priority, the PUSCH has a low priority, and the DCI that schedules the PDSCH also indicates that the PDSCH should not be received.

[0020] Based on the PUSCH processing time and the first time slot resource, a second time slot resource is determined. The second time slot resource is a subset of the first time slot resource, and the time interval between the first symbol of the PUSCH in each time slot of the second time slot resource and the last symbol of the CORESET of the DCI that schedules the PDSCH is less than or equal to the second time.

[0026] Optionally, the first time slot resource may be determined based on one or more of the following: PDSCH priority, PUSCH priority, and PUSCH type, including:

[0027] If at least one symbol of a low-priority PDSCH in a third target time slot overlaps with at least one symbol of a high-priority PUSCH, then the third target time slot is determined not to belong to the first time slot resource.

[0028] or,

[0029] If at least one symbol of the PDSCH of the third target time slot overlaps with at least one symbol of the configured grantPUSCH of the higher-layer signaling configuration, then the third target time slot is determined not to belong to the first time slot resource.

[0030] or,

[0031] If at least one symbol of a low-priority PDSCH in the third target time slot overlaps with at least one symbol of a low-priority PUSCH, then the third target time slot is determined to belong to or not belong to the first time slot resource according to the higher-layer signaling or the indication of the DCI that schedules the PDSCH transmission.

[0032] Optionally, the time slot for receiving PDSCH repetitions can be determined based on one or more of the following: PDSCH priority, PUSCH priority, PDSCH symbol, and PUSCH type.

[0034] Optionally, the third time slot resource is determined based on one or more of the following: PDSCH priority, PUSCH priority, PUSCH type, and PUSCH processing time, including:

[0035] If at least one symbol of a high-priority PDSCH in the fourth target time slot overlaps with at least one symbol of a high-priority PUSCH, the higher-layer signaling or the DCI scheduling the PDSCH transmission indicates that the fourth target time slot belongs to the third time slot resource. If the time interval between the first symbol of the PUSCH and the last symbol of the CORESET of the DCI scheduling the PDSCH is less than or equal to the fourth time, then the fourth target time slot is determined not to belong to the third time slot resource. Alternatively, if the time interval between the first symbol of the PUSCH and the last symbol of the CORESET of the DCI scheduling the PDSCH is greater than the fourth time, then the fourth target time slot is determined to belong to the third time slot resource.

[0036] or,

[0037] If at least one symbol of a high-priority PDSCH in the fourth target time slot overlaps with at least one symbol of a low-priority PUSCH, and if the time interval between the first symbol of the PUSCH and the last symbol of the CORESET of the DCI scheduling the PDSCH is greater than a third time, then the fourth target time slot is determined to belong to the third time slot resource; or, if the time interval between the first symbol of the PUSCH and the last symbol of the CORESET of the DCI scheduling the PDSCH is less than or equal to the third time, then the fourth target time slot is determined not to belong to the third time slot resource.

[0038] Optionally, the third time slot resource is determined based on one or more of the following: PDSCH priority, PUSCH priority, PUSCH type, and PUSCH processing time, including:

[0040] or,

[0041] If at least one symbol of the PDSCH transmission of the fifth target time slot overlaps with at least one symbol of the configuredgrant PUSCH transmission of the higher-layer signaling configuration, then the fifth target time slot is determined not to belong to the third time slot resource.

[0042] or,

[0043] If at least one symbol of a low-priority PDSCH transmission in the fifth target time slot overlaps with at least one symbol of a low-priority PUSCH transmission, the higher-layer signaling or the DCI scheduling the PDSCH transmission indicates that the fifth target time slot belongs to the third time slot resource. Furthermore, if the time interval between the first symbol of the PUSCH transmission and the last symbol of the CORESET of the DCI scheduling the PDSCH is less than or equal to the fifth time slot, then the fifth target time slot is determined not to belong to the third time slot resource. Alternatively, if the time interval between the first symbol of the PUSCH transmission and the last symbol of the CORESET of the DCI scheduling the PDSCH is greater than the fifth time slot, then the fifth target time slot is determined to belong to the third time slot resource.

[0044] Optionally, the first number of times the PDSCH repeats a slot count is determined by the protocol or by the network.

The accompanying drawings are for illustrative purposes only and are not intended to limit the scope of this application. Furthermore, the same reference numerals denote the same parts throughout the drawings. In the drawings:

[0059] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0060] The term "comprising," and any variations thereof, used in the specification and claims of this application, is intended to cover a non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product, or apparatus. Furthermore, the use of "and / or" in the specification and claims indicates at least one of the connected objects, such as A and / or B, indicating the inclusion of A alone, B alone, or both A and B.

[0061] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0062] In existing solutions, for symbols configured as flexible, since there is no definite Time Division Duplex (TDD) transmission direction, it is necessary to consider the conflict between uplink transmission configured at the higher layer and downlink Dynamic Grant (DG). The current solution requires the terminal to adjust the processing time (T...) based on the... proc,2 The relative relationship between the uplink transmission time and the downlink control information (DCI) format detection timing determines when uplink transmission is cancelled. Simply put, if the uplink transmission time is greater than the processing time (T... proc,2If the above condition is met, the uplink transmission can be cancelled; otherwise, the uplink transmission will not be cancelled.

[0063] Furthermore, existing technologies support repeated transmission of the Physical Downlink Shared Channel (PDSCH) in two ways: semi-static configuration of the repetition count and dynamic indication of the repetition count. Semi-static configuration involves configuring the PDSCH aggregation factor (pdsch-AggregationFactor) through Radio Resource Control (RRC) signaling. Upon receiving scheduling signaling, the terminal repeats the transmission on consecutive time slots of the pdsch-AggregationFactor. Dynamic indication of the repetition count involves the base station configuring the repetition count (repetitionNumber) in the PDSCH time-domain resource allocation table. When sending downlink scheduling signaling, the base station indicates the repetition count along with the PDSCH time-domain resource allocation. The terminal receives repeatedly transmitted PDSCH within consecutive repetitionNumber counts. In other words, current PDSCH repeated transmissions can only occur on consecutive time slots; if there is a conflict with TDD configuration, the PDSCH transmission is canceled.

[0064] See Figure 2 This application provides a communication processing method applied to a terminal, the specific steps of which include:

[0065] Step 201: Determine the time slot for receiving PDSCH repetitions based on one or more of the following: PDSCH priority, PUSCH priority, PDSCH symbol, PUSCH symbol, and PUSCH type.

[0066] Optionally, the above PUSCH can be a CG PUSCH.

[0067] Optionally, the priority of the PDSCH may include the priority of the DCI indication that schedules the PDSCH, which may be high priority or low priority.

[0068] Optionally, the priority of PUSCH includes the priority of PUSCH configured by higher-level signaling, which can be high priority or low priority.

[0069] Optionally, the type of the PUSCH includes one of the following:

[0070] The PUSCH is a configured grant for higher-level signaling configuration;

[0071] The data carried by the PUSCH belongs to different service types or different service type groups;

[0072] The data carried by the PUSCH belongs to different service priorities or different service priority groups;

[0073] The data carried by the PUSCH belongs to different logical channels or different logical channel groups;

[0074] The downlink control information for scheduling PUSCH belongs to different physical layer downlink control information formats (DCI format) or different DCI format groups;

[0075] The Radio Network Temporary Identifier (RNTI) used for scrambling scheduling PUSCH physical layer downlink control information is a different RNTI or belongs to a different RNTI;

[0076] The information carried by the downlink control information of the scheduling PUSCH is different.

[0077] In one embodiment of this application, determining the time slot for receiving PDSCH repetitions based on one or more of the following: PDSCH priority, PUSCH priority, PDSCH symbol, PUSCH symbol, and PUSCH type, includes:

[0078] In the case where at least one symbol of the PUSCH in the first target time slot overlaps with at least one symbol of the PDSCH, the terminal determines the first action based on one or more of the following: the priority of the PDSCH, the priority of the PUSCH, and the type of the PUSCH.

[0079] Wherein, the first behavior is determined to be at least one of the following:

[0080] 1) Determine the first target time slot as the time slot for receiving repeated PDSCH;

[0081] By specifying the first target time slot as the time slot for receiving PDSCH, we can not only directly determine the time slots where PDSCH is repeated, but also promote efficient management and optimization of network resources, ultimately improving the quality of service for users.

[0082] 2) Determine that the first target time slot is not a time slot for receiving repeated PDSCH;

[0083] By determining the time slots in which PDSCH data should not be received and adjusting the number of PDSCH repetitions within the remaining time slots, a mechanism is provided for the system to determine the optimal time slots for receiving PDSCH repetitions and to ensure that data transmission in these time slots is both efficient and reliable.

[0084] Optionally, if it is determined that the first target time slot is not the time slot for receiving the PDSCH repetition, the number of PDSCH repetitions may be further adjusted or not adjusted.

[0085] In one embodiment of this application, determining that the first target time slot is not a time slot for receiving repeated PDSCHs based on one or more of the following: PDSCH priority, PUSCH priority, and PUSCH type, includes:

[0086] When the first condition is met, it is determined that the first target time slot is not a time slot for receiving repeated PDSCH.

[0087] The first condition includes at least one of the following:

[0088] 1) The PDSCH has a high priority, the PUSCH has a high priority, and the DCI that schedules the PDSCH also indicates that the PDSCH should not be received.

[0089] 2) The PDSCH has a low priority, and the PUSCH has a high priority;

[0090] 3) The PDSCH has a low priority, the PUSCH has a low priority, and the DCI that schedules the PDSCH also indicates that the PDSCH should not be received.

[0091] 4) The PUSCH mentioned above is a Configuration Grant (CG) for higher-level signaling configuration.

[0092] That is, the priority between PDSCH and PUSCH is not considered. Only PDSCH is dynamically scheduled and PUSCH is semi-statically configured for CG transmission. When the dynamically scheduled PDSCH conflicts with the CG PUSCH, PDSCH is not received and CGPUSCH is transmitted instead.

[0093] In one embodiment of this application, before or after step 201, the method further includes:

[0094] If at least one symbol of the PUSCH in the first target time slot overlaps with at least one symbol of the PDSCH, and the time interval between the first symbol of the PUSCH and the last symbol of the control resource set CORESET of the DCI that schedules the PDSCH is less than or equal to a first time, part or all of the PUSCH is transmitted.

[0095] Optionally, if the first target time slot is determined to be a time slot for receiving repeated PDSCH, the method includes:

[0096] The first target time slot is included in the number of time slots repeated in PDSCH.

[0097] In one embodiment of this application, determining the time slot for receiving PDSCH repetitions based on one or more of the following: PDSCH priority, PUSCH priority, PDSCH symbol, PUSCH symbol, and PUSCH type includes:

[0098] The first time slot resource is determined based on one or more of the following: the priority of PDSCH, the priority of PUSCH, and the type of PUSCH. The first time slot resource includes a time slot for receiving PDSCH.

[0099] Based on the PUSCH processing time and the first time slot resource, a second time slot resource is determined. The second time slot resource is a subset of the first time slot resource, and the time interval between the first symbol of the PUSCH in each time slot of the second time slot resource and the last symbol of the CORESET of the DCI that schedules the PDSCH is less than or equal to the second time.

[0100] Based on the first and second time slot resources, determine the time slot for receiving PDSCH repetitions.

[0101] For example, the terminal determines the time slot of the difference set between the first time slot resource and the second time slot resource as the time slot of PDSCH repetition.

[0102] Optionally, the PUSCH processing time may include, but is not limited to, at least one of the following: 1) the start time of PUSCH transmission, such as the first symbol of PUSCH, 2) the time required for the UE to prepare to send data to the base station via PUSCH, etc.

[0103] In one embodiment of this application, determining the first time slot resource based on one or more of the following: PDSCH priority, PUSCH priority, and PUSCH type, including:

[0104] If at least one symbol of the high-priority PDSCH of the second target time slot overlaps with at least one symbol of the high-priority PUSCH, then the second target time slot is determined to belong to or not belong to the first time slot resource according to the indication of the higher-layer signaling or the DCI that schedules the PDSCH.

[0105] or,

[0106] If at least one symbol of the high-priority PDSCH of the second target time slot overlaps with at least one symbol of the low-priority PUSCH, then the second target time slot resource is determined to belong to the first time slot resource.

[0107] In one embodiment of this application, determining the first time slot resource based on one or more of the following: PDSCH priority, PUSCH priority, and PUSCH type, including:

[0108] If at least one symbol of a low-priority PDSCH in a third target time slot overlaps with at least one symbol of a high-priority PUSCH, then the third target time slot is determined not to belong to the first time slot resource.

[0109] or,

[0110] If at least one symbol of the PDSCH of the third target time slot overlaps with at least one symbol of the configured grantPUSCH of the higher-layer signaling configuration, then the third target time slot is determined not to belong to the first time slot resource.

[0111] or,

[0112] If at least one symbol of a low-priority PDSCH in the third target time slot overlaps with at least one symbol of a low-priority PUSCH, then the third target time slot is determined to belong to or not belong to the first time slot resource according to the higher-layer signaling or the indication of the DCI that schedules the PDSCH transmission.

[0113] In one embodiment of this application, determining the time slot for receiving PDSCH repetitions based on one or more of the following: PDSCH priority, PUSCH priority, PDSCH symbol, and PUSCH type, includes:

[0114] A third time slot resource is determined based on the PDSCH priority and / or the PUSCH priority, and the PUSCH processing time. The third time slot resource includes a time slot for receiving PDSCH.

[0115] In one embodiment of this application, a third time slot resource is determined based on one or more of the following: PDSCH priority, PUSCH priority, PUSCH type, and PUSCH processing time:

[0116] If at least one symbol of a high-priority PDSCH in the fourth target time slot overlaps with at least one symbol of a high-priority PUSCH, the higher-layer signaling or the DCI scheduling the PDSCH transmission indicates that the fourth target time slot belongs to the third time slot resource. If the time interval between the first symbol of the PUSCH and the last symbol of the CORESET of the DCI scheduling the PDSCH is less than or equal to the fourth time slot, then the fourth target time slot is determined not to belong to the third time slot resource. Alternatively, if the time interval between the first symbol of the PUSCH and the last symbol of the CORESET of the DCI scheduling the PDSCH is greater than the fourth time slot, then the fourth target time slot is determined to belong to the third time slot resource.

[0117] or,

[0118] If at least one symbol of a high-priority PDSCH in the fourth target time slot overlaps with at least one symbol of a low-priority PUSCH, and if the time interval between the first symbol of the PUSCH and the last symbol of the CORESET of the DCI scheduling the PDSCH is greater than a third time, then the fourth target time slot is determined to belong to the third time slot resource; or, if the time interval between the first symbol of the PUSCH and the last symbol of the CORESET of the DCI scheduling the PDSCH is less than or equal to the third time, then the fourth target time slot is determined not to belong to the third time slot resource. In one embodiment of this application, determining the third time slot resource based on one or more of the following: PDSCH priority, PUSCH priority, PUSCH type, and PUSCH processing time, includes:

[0119] If at least one symbol of a low-priority PDSCH transmission in the fifth target time slot overlaps with at least one symbol of a high-priority PUSCH transmission, then the fifth target time slot is determined not to belong to the third time slot resource.

[0120] or,

[0121] If at least one symbol of the PDSCH transmission of the fifth target time slot overlaps with at least one symbol of the configuredgrant PUSCH transmission of the higher-layer signaling configuration, then the fifth target time slot is determined not to belong to the third time slot resource.

[0122] or,

[0123] If at least one symbol of a low-priority PDSCH transmission in the fifth target time slot overlaps with at least one symbol of a low-priority PUSCH transmission, the higher-layer signaling or the DCI scheduling the PDSCH transmission indicates that the fifth target time slot belongs to the third time slot resource. Furthermore, if the time interval between the first symbol of the PUSCH transmission and the last symbol of the CORESET of the DCI scheduling the PDSCH is less than or equal to the fifth time slot, then the fifth target time slot is determined not to belong to the third time slot resource. Alternatively, if the time interval between the first symbol of the PUSCH transmission and the last symbol of the CORESET of the DCI scheduling the PDSCH is greater than the fifth time slot, then the fifth target time slot is determined to belong to the third time slot resource.

[0124] In one embodiment of this application, the first number of times the PDSCH repeats a slot count is agreed upon by the protocol or indicated by the network.

[0125] In one embodiment of this application, the priority of the PDSCH is indicated by the DCI that schedules the PDSCH, and / or the priority of the PUSCH is configured by higher-layer signaling.

[0126] In one embodiment of this application, after determining the first time slot resource or the third time slot resource, the method further includes:

[0127] The time slots for receiving PDSCH are included in the number of time slots for PDSCH repetition.

[0128] In this embodiment, the terminal determines the time slot for receiving PDSCH repetitions based on one or more of the following: the priority of PDSCH, the priority of PUSCH configured by higher-layer signaling, the symbol of PDSCH, the symbol of PUSCH, and the type of PUSCH. In this way, when a high-priority PUSCH and a low-priority PDSCH conflict in the time domain, the terminal can be allowed to send uplink PUSCH to meet the low latency requirements of URLLC services.

[0129] The following describes the method for determining PDSCH retransmission resources in this application, with reference to Embodiments 1 and 2.

[0130] Example 1: When at least one symbol of the PUSCH in the first target time slot overlaps with at least one symbol of the PDSCH, the terminal determines that the first target time slot is a time slot where PDSCH is not received, and adjusts the PDSCH repetition count. That is, this PDSCH is included in the PDSCH repetition count K, which means that the actual number of PDSCH transmissions is less than the configured or indicated number of PDSCH repetitions.

[0131] In this context, not receiving PDSCH is equivalent to ignoring PDSCH transmission.

[0132] In this embodiment, the terminal determines the PDSCH repetition count K based on the indication of higher-layer signaling or downlink control information (DCI). The terminal determines the symbols of the PDSCH based on the scheduling DCI, and the same transport block (TB) will occupy the same symbols in K consecutive time slots.

[0133] Furthermore, when at least one symbol of the PUSCH in the first target time slot overlaps with at least one symbol of the PDSCH, if the terminal meets at least one of the following first conditions, then it is determined that the first target time slot is not a time slot for receiving PDSCH repetitions, and the PDSCH repetition count is adjusted:

[0134] Condition 1) The priority indicated in the DCI that schedules this PDSCH is 1 (high priority).

[0135] a) If at least one symbol of the PDSCH in the first target time slot overlaps with at least one symbol of the PUSCH whose physical layer priority index (phy-PriorityIndex) is 1 (high priority) in the higher layer signaling configuration, the DCI of the higher layer signaling configuration or scheduling of the PDSCH indicates whether to receive the PDSCH, i.e. whether to ignore the PDSCH transmission.

[0136] Condition 2) The priority indicated in the DCI that schedules this PDSCH is 0 (low priority).

[0137] a) At least one symbol of the PDSCH in the first target time slot overlaps with at least one symbol of the PUSCH with a higher-layer signaling configuration phy-PriorityIndex of 1 (high priority).

[0138] b) If at least one symbol of the PDSCH in the first target time slot overlaps with at least one symbol of the PUSCH with a higher-layer signaling configuration phy-PriorityIndex of 0 (low priority), and the higher-layer signaling configuration or the DCI scheduling the PDSCH indicates whether to receive the PDSCH further, if at least one symbol of the PUSCH in the first target time slot overlaps with at least one symbol of the PDSCH, and if a PDSCH transmission is not ignored by the terminal, but the time interval between the first symbol of the PUSCH configured by the higher layer and the last symbol of the control resource set (CORESET) of the DCI scheduling the repeated transmission of PDSCH is less than or equal to the first time, then the terminal sends part or all of the PUSCH, that is, the terminal does not cancel part or all of the transmission of the PUSCH.

[0139] It is understood that this embodiment does not specifically limit the "first time".

[0140] Example 2: When at least one symbol of the PUSCH in the first target time slot overlaps with at least one symbol of the PDSCH, the terminal determines that the first target time slot is not the time slot for receiving PDSCH and does not adjust the PDSCH repetition count. That is, this PDSCH is not included in the repetition count, which means that the actual number of PDSCH transmissions is equal to the configured or indicated number of PDSCH repetitions.

[0141] In this embodiment, the terminal determines the number of repetitions K of PDSCH in the following ways:

[0142] The terminal determines the number of times K of PDSCH repetition based on the instruction of the DCI that configures or schedules PDSCH according to the higher-layer signaling. The terminal determines the time-domain symbol resource allocation of PDSCH according to the DCI that schedules PDSCH, and the same TB will occupy the same symbol resource allocation in K time slots.

[0143] Whether a particular time slot is included in K is determined as follows:

[0144] Method 1: First, determine the first time slot resource based on the priority of the DCI indication of the PDSCH scheduling and / or the priority of the PUSCH configured by the higher layer signaling, that is, determine the set of available time slots, and then determine whether to actually receive the time slots of PDSCH duplication based on the PUSCH processing time.

[0145] Step 1:

[0146] 1) If the priority of the DCI indicator for scheduling PDSCH is 1 (high priority):

[0147] a) If at least one symbol allocation of the PDSCH of the second target time slot overlaps with at least one symbol of the PUSCH with a higher-layer signaling configuration phy-PriorityIndex of 1 (high priority), the higher-layer signaling configuration or the DCI of the PDSCH scheduling indicates whether the second target time slot belongs to or does not belong to the first time slot resource, that is, whether the second target time slot is included in K.

[0148] b) If at least one symbol of the PDSCH of the second target time slot overlaps with at least one symbol of the PUSCH with a higher-layer signaling configuration phy-PriorityIndex of 0 (low priority), then the second target time slot belongs to the first time slot resource, that is, the second target time slot is counted in K.

[0149] 2) If the priority of the DCI indication for scheduling PDSCH is 0 (low priority):

[0150] a) If at least one symbol of the third target time slot PDSCH overlaps with at least one symbol of the PUSCH with a higher-layer signaling configuration phy-PriorityIndex of 1 (high priority), then the third target time slot does not belong to the first time slot resource, that is, the third target time slot is not included in K.

[0151] b) If at least one symbol of the PDSCH in the third target time slot overlaps with at least one symbol of the PUSCH in the higher-layer signaling configuration phy-PriorityIndex of 0 (low priority), the higher-layer signaling configuration or the DCI of the PDSCH scheduling indicates whether the third target time slot belongs to or does not belong to the first time slot resource, that is, whether the third target time slot is included in K.

[0152] Step 2:

[0153] The terminal determines the first time slot resource based on K and the above method. The first time slot resource includes time slots for receiving PDSCH. The first time slot resource can also be referred to as the first PDSCH reception opportunity set (e.g., including potential opportunities to receive PDSCH, i.e., time slots included in K).

[0154] For each time slot in the first time slot resource, if the time interval between the first symbol of the PUSCH configured by the higher layer and the last symbol of the CORESET of the DCI that is scheduled to repeatedly transmit PDSCH is less than the second time, then the time slot is included in the second time slot resource (or called the second PDSCH reception timing set), and the terminal does not cancel all or part of the transmission of the PUSCH that overlaps with it.

[0155] The terminal determines the time slot for receiving PDSCH repetition based on the first time slot resource and the second time slot resource. For example, the terminal receives PDSCH on the time slot of the difference set of the first time slot resource and the second time slot resource.

[0156] It is understood that this embodiment does not specifically limit the second time.

[0157] Method 2: Simultaneously determine the third time slot resource based on the priority indicated by the DCI of the PDSCH scheduling and / or the priority determination of the PUSCH configured by the higher layer signaling and the PUSCH processing time. The third time slot resource includes a time slot for receiving PDSCH.

[0158] 1) The priority indicated in the DCI for scheduling PDSCH is 1 (high priority):

[0159] a) If at least one symbol of the PDSCH of the fourth target time slot overlaps with at least one symbol of the PUSCH with a higher-layer signaling configuration phy-PriorityIndex of 1 (high priority), the higher-layer signaling configuration or the DCI of the PDSCH scheduling indicates whether the fourth target time slot belongs to or does not belong to the third time slot resource, that is, whether the fourth target time slot can be included in K.

[0160] i. If the higher-layer signaling configuration or the DCI of the scheduling PDSCH indicates that the fourth target time slot can be included in K, then perform either 1 or 2 below.

[0161] 1. If the time interval between the first symbol of the PUSCH and the last symbol of the CORESET of the DCI that schedules the repeated transmission of the PDSCH is less than or equal to (within) the fourth time, then it is determined that the fourth target time slot does not actually belong to the third time slot resource, that is, the fourth target time slot is not included in K (the transmission of part or all of the PUSCH is not cancelled).

[0162] 2. If the time interval between the first symbol of PUSCH and the last symbol of the CORESET of the DCI that schedules repeated PDSCH transmission is greater than the fourth time interval, then it is determined that the fourth target time slot actually belongs to the third time slot resource, that is, the fourth target time slot is actually counted in K (PUSCH transmission is cancelled).

[0163] b) If at least one symbol of the PDSCH in the fourth target time slot overlaps with at least one symbol of the PUSCH with a higher-layer signaling configuration phy-PriorityIndex of 0 (low priority), then perform either i or ii.

[0164] i. If the time interval between the first symbol of PUSCH and the last symbol of the CORESET of the DCI that schedules PDSCH is greater than the third time interval, then the fourth target time slot belongs to the third time slot resource, that is, the fourth target time slot is included in K.

[0165] ii. If the time interval between the first symbol of PUSCH and the last symbol of the CORESET of the DCI that schedules PDSCH is less than or equal to the third time interval, then the fourth target time slot does not belong to the third time slot resource, that is, the fourth target time slot is not included in K.

[0166] 2) The priority indicated in the DCI for scheduling PDSCH is 0 (low priority):

[0167] a) If at least one symbol allocation of the PDSCH of the fifth target time slot overlaps with at least one symbol of the PUSCH with a higher-layer signaling configuration phy-PriorityIndex of 1 (high priority), then the fifth target time slot is determined not to belong to the third time slot resource, that is, the fifth target time slot is not included in K.

[0168] b) If at least one symbol of the PDSCH of the fifth target time slot overlaps with at least one symbol of the PUSCH with a higher-layer signaling configuration phy-PriorityIndex of 0 (low priority), determine whether the fifth target time slot belongs to or does not belong to the third time slot resource based on the higher-layer signaling configuration or the DCI indication of the PDSCH scheduling, i.e., whether the fifth target time slot is included in K:

[0169] i. If the higher-layer signaling configuration or the DCI of the scheduling PDSCH indicates that the fifth target time slot belongs to the third time slot resource, that is, the fifth target time slot can be included in K, then execute 1 or 2 below;

[0170] 1. If the time interval between the first symbol of PUSCH and the last symbol of the CORESET of the DCI that schedules repeated transmission of PDSCH is less than or equal to the fifth time slot, then the fifth target time slot does not belong to the third time slot resource, that is, the fifth target time slot is not actually included in K.

[0171] 2. If the time interval between the first symbol of PUSCH and the last symbol of the CORESET of the DCI that is scheduled to be repeatedly transmitted by PDSCH is greater than the fifth time interval, then the fifth target time slot belongs to the third time slot resource, that is, the fifth target time slot is actually counted in K.

[0172] Furthermore, for Embodiments 1 and 2, the protocol predefines or the network instructs via signaling that for repeatedly transmitted PUSCH, the first number of times the available PDSCH slots are counted according to the above rules is, for example, 1 or N. For example, if it is 1, only the first PUSCH is counted for available PDSCH slots according to the above rules, and the other PUSCH slots are all included in K, or only the first N times of repeated PUSCH transmissions are used to determine whether to include them in K, and the others are included in K by default.
