Description

Technical Field

[0001] The present application relates to the field of communications. Background Art

[0002] Currently, the NR (New Radio) system supports a maximum of one semi-persistent scheduling (SPS) configuration on a BWP (Bandwidth Part) in a serving cell. In addition, according to the requirements of the existing business model, the SPS period is relatively long, with a minimum period of 10ms. However, with the introduction of new business models, the NR system needs to be able to activate multiple semi-persistent scheduling configurations simultaneously on a BWP in a serving cell. In addition, the minimum transmission period of SPS also needs to be significantly shortened. Therefore, when multiple SPS configurations on a BWP in a serving cell are activated at the same time, their corresponding HARQ-ACK (Hybrid Automatic Repeat request-Acknowledgement) information may be sent within the same time unit. However, existing technologies cannot solve this problem.

[0003] It should be noted that the above introduction to the technical background is merely intended to provide a clear and complete description of the technical solutions of this application and facilitate understanding by those skilled in the art. Simply because these solutions are described in the background technology section of this application, it should not be assumed that the above technical solutions are well known to those skilled in the art. Summary of the Invention

[0004] The inventors discovered that when at least two SPS configurations are activated simultaneously on the same BWP of the same serving cell, their corresponding HARQ-ACK information may be sent within the same time unit. However, existing mechanisms cannot handle this situation. Without a corresponding solution, the period, time domain location, etc. corresponding to the SPS configuration will be restricted. Moreover, since the HARQ-ACK information corresponding to multiple activated SPS configurations cannot be sent simultaneously, the HARQ-ACK information corresponding to some SPS configurations may be delayed, thereby increasing the latency of the corresponding HARQ-ACK feedback, thereby affecting system performance.

[0005] In order to solve at least one of the above problems or solve other similar problems, the embodiments of the present application provide a signal sending method, device and system, so that when at least two SPS configurations are activated simultaneously on the same BWP in the same cell, their corresponding HARQ-ACK information can be fed back within the same time unit, which not only enables the network side to more flexibly configure multiple SPSs in the same BWP in the same cell (more flexible period, starting position, etc.), but also reduces the delay of the HARQ-ACK information corresponding to the SPS configuration.

The term "and / or" includes any one and all combinations of one or more of the associated listed terms. The terms "comprising", "including", "having", etc. refer to the presence of the stated features, elements, components or components, but do not exclude the presence or addition of one or more other features, elements, components or components.

Furthermore, the term "said" should be understood to include both singular and plural forms, unless the context clearly indicates otherwise. Furthermore, the term "according to" should be understood to mean "at least in part based on...", and the term "based on" should be understood to mean "at least in part based on...", unless the context clearly indicates otherwise.

[0044] In the embodiments of the present application, the term "communication network" or "wireless communication network" may refer to a network that complies with any of the following communication standards, such as Long Term Evolution (LTE), enhanced Long Term Evolution (LTE-A, LTE-Advanced), Wideband Code Division Multiple Access (WCDMA), High-Speed ​​Packet Access (HSPA), etc.

[0045] Furthermore, communication between devices in the communication system may be carried out according to communication protocols of any stage, for example, including but not limited to the following communication protocols: 1G (generation), 2G, 2.5G, 2.75G, 3G, 4G, 4.5G and future 5G, New Radio (NR), etc., and / or other currently known or future communication protocols to be developed.

[0046] In the embodiments of the present application, the term "network device" refers to, for example, a device in a communication system that connects a terminal device to a communication network and provides services to the terminal device. Network devices may include, but are not limited to, the following devices: base station (BS), access point (AP), transmission reception point (TRP), broadcast transmitter, mobile management entity (MME), gateway, server, radio network controller (RNC), base station controller (BSC), etc.

[0047] Base stations may include, but are not limited to, NodeB (NB), evolved NodeB (eNodeB or eNB), and 5G base stations (gNB), among others. They may also include remote radio heads (RRHs), remote radio units (RRUs), relays, or low-power nodes (e.g., femto, pico, etc.). The term "base station" may include some or all of their functions, and each base station may provide communication coverage for a specific geographic area. The term "cell" may refer to a base station and / or its coverage area, depending on the context in which the term is used.

[0048] In the embodiments of the present application, the term "user equipment" (UE) refers to, for example, a device that accesses a communication network through a network device and receives network services, and may also be referred to as "terminal equipment" (TE). A terminal device may be fixed or mobile, and may also be referred to as a mobile station (MS), a terminal, a user, a subscriber station (SS), an access terminal (AT), a station, and the like.

[0049] Among them, terminal devices may include but are not limited to the following devices: cellular phones, personal digital assistants (PDAs), wireless modems, wireless communication devices, handheld devices, machine-type communication devices, laptop computers, cordless phones, smart phones, smart watches, digital cameras, etc.

[0050] For another example, in scenarios such as the Internet of Things (IoT), the terminal device can also be a machine or device for monitoring or measurement, such as but not limited to: machine type communication (MTC) terminal, vehicle-mounted communication terminal, device-to-device (D2D) terminal, machine-to-machine (M2M) terminal, and so on.

[0051] Currently, in the NR system, a data signal reception feedback mechanism is introduced for physical layer downlink data transmission. Specifically, the UE will receive the PDSCH at the specified time-frequency position according to the instructions of the base station (PDCCH, physical downlink control channel). At the same time, the UE needs to make corresponding HARQ feedback for the reception of the PDSCH. When the UE successfully decodes the PDSCH at the time-frequency position, the UE needs to feedback ACK to the base station; when the UE fails to decode the PDSCH at the time-frequency position, the UE needs to feedback NACK to the base station. By receiving the HARQ feedback from the UE, the base station can determine which downlink data needs to be retransmitted accordingly. At the same time, it can also determine the quality of the downlink channel based on the ratio of ACK and NACK in the HARQ feedback, and thus adjust the modulation and coding method of the downlink transmission accordingly.

[0052] In addition, in the NR system, the scheduling of downlink data is mainly divided into two methods: dynamic scheduling and semi-persistent scheduling (SPS). For dynamic scheduling, one PDCCH schedules a corresponding PDSCH. Semi-persistent scheduling means that one PDCCH can activate a series of PDSCH transmissions, where a series of PDSCHs are repeatedly transmitted with a period of P. When the UE receives the activation signaling of semi-persistent scheduling, the UE obtains the time-frequency position of the first PDSCH according to the indication in the PDCCH and the pre-configured indication. Thereafter, the UE continues to periodically receive or monitor the PDSCH in the time domain according to the previously stored PDCCH indication and related configuration information. When the UE receives the deactivation signaling of semi-persistent scheduling, the UE stops receiving or monitoring the corresponding PDSCH.

[0053] Regardless of dynamic scheduling or semi-persistent scheduling, for each PDSCH, the UE generally feeds back ACK or NACK information, that is, performing HARQ feedback.

[0054] For dynamic scheduling, the downlink control information (DCI) indicating the corresponding PDSCH contains a PDSCH-to-HARQ_feedback timing indicator field, which is used to indicate the offset k between the PDSCH and the PUCCH resource carrying the corresponding HARQ-ACK information bit (abbreviated as HARQ bit), such as Figure 1 That is, when the PDSCH is in slot n, its corresponding ACK or NACK feedback is sent in slot n+k. In addition, the DCI also includes a PUCCH resource indicator field, which is used to indicate the PUCCH resource carrying the corresponding HARQ-ACK information bits.

[0055] For semi-persistent scheduling, the DCI used to activate SPS contains the PDSCH-to-HARQ_feedbacktiming indicator field, which is used to indicate the offset k between each PDSCH and the PUCCH resource carrying the corresponding HARQ-ACK information bit, such as Figure 2 In addition, in addition to activating the PDSCH directly indicated by the DCI, if there is only HARQ feedback corresponding to the PDSCH (without the corresponding PDCCH) in the corresponding time slot, the UE determines the PUCCH resources used to carry the corresponding HARQ-ACK information bits according to IE n1PUCCH-AN in the SPS configuration.

[0056] When ACK / NACK feedback (i.e. HARQ-ACK information) for more than one PDSCH is instructed to be sent in the same time slot, in order to avoid power loss, the ACK / NACK information bits corresponding to semi-persistent scheduling and the ACK / NACK information bits corresponding to dynamic scheduling need to be multiplexed in the same uplink resource. Figure 3 As shown, when the ACK / NACK feedback of dynamic scheduling and semi-persistent scheduling are instructed to be sent in the same time slot, their corresponding ACK / NACK feedback contents will be put together and fed back on the uplink resources indicated by the dynamic scheduling (DCI#2).

[0057] In addition, when HARQ-ACK information corresponding to different PDSCHs is transmitted in the same time slot, the UE determines the order of the corresponding HARQ-ACK information bits according to predefined rules to generate the corresponding HARQ-ACK codebook. Once the codebook is generated, the UE will send an uplink signal (PUCCH / PUSCH) to carry the codebook.

[0058] In the description of the embodiments of the present application, HARQ-ACK information, that is, HARQ feedback information, may include both ACK information bits and NACK information bits.

[0059] exist Figure 1-Figure 3 In the corresponding description, time slot is used as the time unit, but the present application is not limited to this. The time unit involved in the present application may also be symbol (symbol) or sub-slot (sub-slot) or frame (frame) or sub-frame (sub-frame), etc.

[0060] The following describes the scenarios of the embodiments of the present application through examples, but the embodiments of the present application are not limited thereto.

[0061] Figure 4It is a schematic diagram of the application scenario of the embodiment of the present application, such as Figure 4 As shown, in the embodiment of the present application, for the convenience of explanation, the concept of a first set is defined, and the first set includes at least {SPS PDSCH #1, SPS PDSCH #2, ..., SPS PDSCH #M}, where one element represents one SPS PDSCH reception, denoted as SPS PDSCH #m, m = 1, 2, 3, ..., M, (M> = 2). Moreover, in the embodiment of the present application, SPS PDSCH #1, SPS PDSCH #2, ..., SPS PDSCH #M correspond to the same BWP or CC or serving cell or the same BWP of the same serving cell.

[0062] In the embodiment of the present application, one implementation is that the terminal device is configured in the time slot nK m Receive SPSPDSCH#m, and SPS PDSCH#m is activated, that is, the SPS corresponding to SPS PDSCH#m is configured in time slot nK m In the active state. Among them, n refers to the time slot corresponding to the SPS PDSCH#m for sending feedback information; K m Refers to the time domain offset between the PDSCH of SPS PDSCH#m and the corresponding HARQ feedback (PDSCH-to-HARQ-ACK-feedback timing value), that is, the time slot interval between the time slot in which SPS PDSCH#m is received and the time slot in which the corresponding HARQ-ACK information is received. It should be noted that the HARQ-ACK information corresponding to all SPS PDSCH receptions in the first set is sent in the same time slot (also known as time slot n).

[0063] In another embodiment of the present application, the terminal device is configured in time slot n m Receive SPSPDSCH#m, and SPS PDSCH#m is activated, that is, the SPS corresponding to SPS PDSCH#m is configured in time slot n m In the active state. Here, the (uplink) sub-time slot corresponding to SPS PDSCH#m is n'–K' m , that is, the PDSCH end symbol corresponding to SPS PDSCH#m is in sub-slot n'–K' m Wherein, n' refers to the sub-time slot corresponding to the SPS PDSCH#m in which the feedback information is sent, that is, the starting symbol of the uplink signal corresponding to the feedback information is in the sub-time slot n'; K' mRefers to the subslot interval between the subslot corresponding to the end symbol of the PDSCH corresponding to SPS PDSCH#m and the subslot corresponding to the end symbol of the HARQ feedback corresponding to SPS PDSCH#m (PDSCH-to-HARQ-ACK-feedback timing value). It should be noted that the HARQ-ACK information corresponding to all SPS PDSCH receptions in the first set is sent in the same subslot (i.e., subslot n').

[0064] The above description only takes time slots and sub-time slots as examples. The time unit in the above description may also be a subframe, a symbol, or a frame.

[0065] Various embodiments of the present application are described below with reference to the accompanying drawings. These embodiments are merely exemplary and are not intended to limit the present application.

[0066] Embodiments of the first aspect

[0067] An embodiment of the first aspect of the present application provides a signal sending method, which is applied to a terminal device. Figure 5 This is a schematic diagram of a signal sending method according to an embodiment of the first aspect of the present application. Figure 5 , the method comprising:

[0068] Operation 501: A terminal device generates a first feedback signal according to at least a first set, where the first set includes at least two SPS PDSCH receptions, and the SPS PDSCH receptions in the first set correspond to the same bandwidth part (BWP) or component carrier or serving cell or the same BWP of the same serving cell;

[0069] Operation 502: The terminal device sends the first feedback signal.

[0070] According to an embodiment of the present application, on the same BWP or CC or serving cell or the same BWP of the same serving cell (that is, the same BWP of a serving cell), the HARQ ACK information corresponding to at least two SPS PDSCH receptions can be fed back within the same time unit. Thus, the network device can more flexibly configure multiple SPSs in the same BWP or CC or serving cell or the same BWP of the same serving cell, and can also reduce the delay of the SPS feedback information.

[0071] In an embodiment of the present application, SPS PDSCH reception means that the terminal device monitors or receives the corresponding PDSCH according to the SPS activation DCI and the corresponding SPS configuration information. When the terminal device successfully decodes the SPS PDSCH at the corresponding time-frequency position, ACK is fed back. If the SPS PDSCH is not successfully decoded at the corresponding time-frequency position, NACK is fed back. Here, SPS activation DCI (i.e., DCI for activating SPS) refers to, with respect to the corresponding SPS configuration, the most recent SPS activation DCI in the time domain, that is, there is no other SPS activation DCI (belonging to the same SPS configuration) between the SPS activation DCI and its corresponding SPS PDSCH. In addition, the SPS activation DCI can be, for example, a DCI format scrambled by CS-RNTI. Among them, for example, the new data indicator field (new data indicator field) for enabling the transport block in the SPS activation DCI is "0", that is, "a new dataindicator field for the enabled transport block is set to'0'".

[0072] by Figure 2 For example, the SPS activation DCI is the leftmost DCI, and SPS PDSCH reception means that the UE monitors / receives the corresponding PDSCH in slot n or receives / monitors the corresponding PDSCH in slot n+P, or subsequently monitors / receives the corresponding PDSCH in slots with a period of P (for example, slot n+2P). Figure 3 For example, if the SPS activation DCI is DCI#1, SPS PDSCH reception means that the UE monitors / receives the corresponding PDSCH in slot n or receives / monitors the corresponding PDSCH in slot n+P, or subsequently monitors / receives the corresponding PDSCH in slots with a period of P (for example, slot n+2P). Figure 3 In the example, DCI#2 is dynamic DCI instead of the aforementioned SPS activation DCI, and the PDSCH scheduled by DCI#2 is not the PDSCH corresponding to the aforementioned SPS PDSCH reception.

[0073] In at least one embodiment of the embodiments of the present application, the SPS PDSCH reception in the first set corresponds to the same HARQ-ACK codebook, thereby enabling better utilization of system resources while also ensuring transmission reliability. For example, the HARQ-ACK feedback of SPS PDSCH#1, SPS PDSCH#2, ..., SPS PDSCH#M corresponds to the same HARQ-ACK codebook, which can be slot-based or sub-slot-based, but the present application is not limited thereto.

[0074] In one embodiment, the HARQ-ACK codebook identifiers of the SPS configurations corresponding to the SPS PDSCH receptions in the first set (SPS PDSCH#1, SPS PDSCH#2, ..., SPS PDSCH#M) are the same.

[0075] For example, in the first set, all SPS PDSCH receptions corresponding to semi-persistent scheduling contain 'codebook = slot-based' in the RRCIE, that is, all PDSCH HARQ feedback belongs to the slot-based HARQ-ACK codebook. Here, slot-based means that the time domain position of the uplink resource corresponding to the HARQ-ACK information is determined by the time domain indication in slot units.

[0076] For another example, in the first set, the RRC IE related to semi-persistent scheduling corresponding to all SPS PDSCH receptions contains 'codebook = sub-slot-based', that is, all PDSCH HARQ feedback belongs to the sub-slot-based HARQ-ACK codebook. Here, sub-slot-based means that the time domain position of the uplink resource corresponding to the HARQ-ACK information is determined by the time domain indication in sub-slot units.

[0077] For another example, in the first set, all RRC IEs related to semi-persistent scheduling corresponding to SPS PDSCH reception contain 'codebook=1', that is, all HARQ-ACK information of PDSCH corresponds to the first HARQ-ACK codebook.

[0078] For another example, in the first set, the RRC IE related to semi-persistent scheduling corresponding to all SPS PDSCH receptions contains 'codebook=2', that is, the HARQ-ACK information of all PDSCHs corresponds to the second HARQ-ACK codebook.

[0079] The above examples are just illustrations, and the present application is not limited thereto. Other similar examples can be derived based on the above examples, which will be omitted here.

[0080] In another embodiment, the HARQ-ACK codebook identifier in the SPS activation DCI corresponding to the SPS PDSCH receptions (SPS PDSCH#1, SPS PDSCH#2, ..., SPS PDSCH#M) in the first set is the same. Here, the SPS activation DCI corresponding to the SPS PDSCH reception means that the SPS PDSCH reception and the SPS activation DCI correspond to the same SPS configuration.

[0081] For example, the SPS activation DCI contains a 1-bit field where a codepoint of '0' represents the slot-based HARQ-ACK codebook, and a codepoint of '1' represents the sub-slot-based HARQ-ACK codebook. The value of this field in the SPS activation DCI corresponding to SPS PDSCH#1, SPS PDSCH#2, ..., SPS PDSCH#M is the same ('0' / '1').

[0082] For another example, the SPS activation DCI includes a field with a size of 2 bits, where a codepoint of '00' represents HARQ-ACK codebook 1, a codepoint of '01' represents HARQ-ACK codebook 2, a codepoint of '10' represents HARQ-ACK codebook 3, and a codepoint of '11' represents HARQ-ACK codebook 4. Here, the value of this field in the SPS activation DCI corresponding to SPS PDSCH#1, SPS PDSCH#2, ..., SPS PDSCH#M is the same.

[0083] In at least one embodiment of the embodiments of the present application, the first feedback signal includes feedback information corresponding to the SPS PDSCH reception in the first set, and the order of the feedback information corresponding to the SPS PDSCH reception in the first set in the first feedback signal is related to (or determined by) at least one of the following methods:

[0084] The order of the starting time domain position or the ending time domain position of the PDSCH corresponding to the SPS PDSCH reception in the first set;

[0085] an ascending or descending order of the SPS configuration IDs corresponding to the SPS PDSCH reception in the first set; and

[0086] The order of the starting time domain position or the ending time domain position of the SPS activation DCI corresponding to the SPS PDSCH reception in the first set.

[0087] Thus, the terminal device and the network device can determine the meaning of the HARQ-ACK information according to the order of the bits of the HARQ-ACK information. That is, they can determine whether the corresponding SPS PDSCH in the first set is successfully received.

[0088] In addition, when the above order is related to the starting time domain position or the ending time domain position of the PDSCH corresponding to the SPS PDSCH reception in the first set, not only can the starting / ending position of the PDSCH be used to distinguish the order of the corresponding HARQ-ACK information bits (bits), but also the SPS PDSCH reception with an earlier PDSCH time domain position can be given priority processing, thereby generating HARQ-ACK information bits earlier, which complies with the hardware processing timing, speeds up the processing process, and saves system resource overhead.

[0089] In addition, when the above order is related to the ascending or descending order of the SPS configuration ID corresponding to the SPS PDSCH reception in the first set, it not only enables the SPS configuration ID corresponding to the PDSCH to distinguish the order of the corresponding HARQ-ACK information bits, but also enables the PDSCHs corresponding to different SPS configuration IDs to have different priority levels. That is, when the UE cannot transmit all the HARQ-ACK bits corresponding to the SPS PDSCH receptions in the first set, it can remove some bits according to the order, so that the number of bits of the feedback information matches the corresponding transmission resources.

[0090] In addition, when the above order is related to the start time domain position or the end time domain position of the SPS activation DCI corresponding to the SPS PDSCH reception in the first set, it can not only enable the SPS activation DCI corresponding to the PDSCH to distinguish the order of the corresponding HARQ-ACK information bits, but also enable the PDSCHs corresponding to different SPS activation DCIs to have different priority levels. That is, when the UE cannot transmit all the HARQ-ACK information bits corresponding to the SPS PDSCH receptions in the first set, it can remove some bits according to the order, so that the number of bits of the feedback information matches the corresponding transmission resources.

[0091] Similar to the aforementioned time unit, the above-mentioned time domain position can be one of a frame, a subframe, a slot, a sub-slot, and a symbol, but the present application is not limited thereto.

[0092] For example, it is assumed that the feedback information bits corresponding to SPS PDSCH#1, SPS PDSCH#2, ..., SPS PDSCH#M are O1, O2, ..., O M In the first feedback signal, it is assumed that the order of the feedback information bits is {O1, O2, ..., O M}(from O1 to O M ), the order is determined by one of the following methods:

[0093] Method 1: The start or end position of the PDSCH signal, that is, the above order is determined by the start / end position of the PDSCH signal corresponding to SPS PDSCH#m. For example, the starting symbol of the PDSCH signal corresponding to SPS PDSCH#m is StartPDSCH#m, then:

[0094] Arranged in ascending order of the start position of the corresponding PDSCH signal in the time domain: StartPDSCH#1>=StartPDSCH#2>=…>=StartPDSCH#M;

[0095] Arranged in descending order in the time domain according to the starting position of the corresponding PDSCH signal means: StartPDSCH#1<=StartPDSCH#2<=…<=StartPDSCH#M.

[0096] Method 2, SPS configuration ID, that is, the above order is determined by the size of the SPS configuration ID (SPS config#m) corresponding to SPS PDSCH#m, for example,

[0097] In ascending order of corresponding SPS configuration IDs: SPS config#1>=SPS config#2>=…>=SPS config#M;

[0098] In descending order of the corresponding SPS configuration ID: SPS config#1<=SPS config#2<=…<=SPS config#M.

[0099] Method 3: The starting or ending position of the SPS activation DCI, that is, the above order is determined by the starting / ending position of the SPS activation DCI corresponding to SPS PDSCH#m. For example, the starting symbol of the SPS activation DCI corresponding to SPS PDSCH#m is StartPDCCH#m, then:

[0100] Arranged in ascending order of the start position of the corresponding PUCCH signal in the time domain: StartPDCCH#1>=StartPDCCH#2>=…>=StartPDCCH#M;

[0101] Arranged in descending order in the time domain according to the starting position of the corresponding PUCCH signal means: StartPDCCH#1<=StartPDCCH#2<=…<=StartPDCCH#M.

[0102] Here, the SPS activation DCI corresponding to the SPS PDSCH#m refers to the SPS activation DCI that is closest to the SPS PDSCH#m in the time domain and corresponds to the same SPS configuration.

[0103] The above three methods can be used separately or in combination. For example, first compare the starting position of PDSCH. If they are the same, further compare the size of SPS configuration ID, and vice versa. For another example, first compare the size of SPS configuration ID, and then compare the position of SPS activation DCI, and vice versa.

[0104] In the above-mentioned operation 501 of the embodiment of the present application, in at least one embodiment, the terminal device may generate the above-mentioned first feedback signal according to the first set and the maximum number of HARQ-ACK information bits. Here, the maximum number of HARQ-ACK information bits refers to: the maximum number of HARQ-ACK information bits related to SPS in an uplink signal (e.g., PUCCH).

[0105] In one embodiment, the maximum number of HARQ-ACK information bits may be indicated by RRC (Radio Resource Control) signaling, that is, configured by the network device through RRC signaling.

[0106] For example, the network device sends RRC signaling to the terminal device, which indicates that the terminal device is allowed to send a maximum of N packets in one uplink resource / signal. max HARQ feedback bits related to SPS, then N max is the maximum number of HARQ-ACK information bits mentioned above, and

[0107] When the total number of HARQ-ACK bits corresponding to all SPS PDSCH receptions in the first set is less than or equal to N max When the first feedback signal includes all SPS HARQ feedback bits corresponding to the SPS PDSCH reception in the first set;

[0108] When the total number of HARQ-ACK bits corresponding to all SPS PDSCH receptions in the first set is greater than N max When the first feedback signal contains a maximum of N max HARQ-ACK bits corresponding to the SPS PDSCH reception in the first set. At this time, only HARQ-ACK information corresponding to a portion of the SPS PDSCH reception in the first set is included in the first feedback signal.

[0109] In an embodiment of the present application, the terminal device can determine the above-mentioned part of the SPS PDSCH reception according to the order of the start / end domain positions of the PDSCH corresponding to the SPS PDSCH reception in the first set. For example, the first feedback signal only includes the feedback information (HARQ-ACK bit) of the SPS PDSCH reception at the front of the corresponding PDSCH start position, so that the number of transmitted bits is less than or equal to the above-mentioned N max .

[0110] In an embodiment of the present application, the terminal device may also determine the above-mentioned part of the SPS PDSCH reception according to the ascending / descending order of the SPS configuration ID corresponding to the SPS PDSCH reception in the first set. For example, the first feedback signal only includes the feedback information (HARQ-ACK bit) of the PDSCH reception corresponding to the smaller SPS configuration ID, so that the number of transmitted bits is less than or equal to the above-mentioned N max .

[0111] In an embodiment of the present application, the terminal device may also determine the reception of the above-mentioned part of the SPS PDSCH according to the order of the start / end domain positions of the SPS activation DCI corresponding to the SPS PDSCH reception in the first set. For example, the first feedback signal only includes the feedback information (HARQ-ACK bit) of the earlier PDSCH reception of the corresponding SPS activation DCI, so that the number of transmitted bits is less than or equal to the above-mentioned Nmax .

[0112] The above three methods can be used separately or in combination. For example, first compare the starting positions of the PDSCH. If they are the same, then further compare the size of the SPS configuration ID, and vice versa. For another example, first compare the size of the SPS configuration ID, then compare the position of the SPS activation DCI, and vice versa. The present application is not limited to this.

[0113] In another embodiment, the maximum number of HARQ-ACK information bits may also be related to the capacity of the first feedback signal. max The HARQ feedback bits associated with the SPS are not indicated by RRC signaling but are related to the capacity of the first feedback signal, for example, equal to each other. The capacity is related to the time-frequency domain resources, modulation scheme (MCS) and / or code rate of the above-mentioned first feedback signal, which will not be described in detail in this application. As a result, additional indication signaling indicating the maximum number of HARQ-ACK information bits can be avoided, thereby reducing system resource overhead.

[0114] In the above-mentioned operation 501 of the embodiment of the present application, in at least one embodiment, the terminal device can generate the above-mentioned first feedback signal based on the first set and the maximum number of ACKs related to HARQ-ACK information. Here, HARQ-ACK information refers to HARQ-ACK information related to SPS.

[0115] In one embodiment, the maximum number of ACKs related to HARQ-ACK information refers to the maximum number of ACKs related to HARQ-ACK information in an uplink signal (e.g., PUCCH), which can be indicated by RRC signaling, that is, configured by the network device through RRC signaling.

[0116] For example, the network device sends an RRC signaling to the terminal device, which indicates that the terminal device is allowed to send a maximum of P SPS-related 'ACKs' in one uplink resource, that is, it indicates that the terminal device has a maximum of P valid SPS PDSCH receptions, and the HARQ information corresponding to the reception of other SPS PDSCHs in the first set is NACK. Therefore, the number of ACKs that may be included in the feedback information is 0, 1, 2, ..., P. Assuming that the number of HARQ feedback bits related to SPS in the first feedback signal is N, the possible states of the feedback are 1, Therefore, the terminal device does not need to generate N bits of HARQ-ACK information in the first feedback signal, but instead generates a certain number of bits corresponding to all the possible states mentioned above, that is, the number of bits generated in the first feedback signal is: (P = 0, 1, 2, ...). In this way, RRC signaling can flexibly configure the number of ACKs, allowing more SPS PDSCHs to feedback HARQ-ACK information within the same time unit. Furthermore, limiting the number of ACKs can significantly reduce the possible combinations of feedback information, thereby saving the information bit overhead required for HARQ feedback.

[0117] In another embodiment, the maximum number of ACKs related to HARQ-ACK information is predefined. That is, the maximum number of P ACKs allowed to be sent related to SPS is not indicated by RRC but is predefined, for example, to 2. This avoids additional indication signaling (to indicate the number of ACKs) and saves signaling overhead.

[0118] According to the above method of the embodiment of the present application, the position of the HARQ-ACK information bit corresponding to each SPS PDSCH can be determined in the HARQ-ACK information, thereby, the network device and the terminal device can determine the meaning of the feedback information according to the order of the HARQ-ACK information bits.

[0119] In the embodiments of the present application, in at least one embodiment, the above-mentioned first feedback signal only includes the HARQ-ACK information corresponding to the PDSCH reception that does not correspond to the PDCCH (PDSCH without corresponding PDCCH), and does not include the HARQ-ACK information corresponding to the PDSCH reception that corresponds to the PDCCH (PDSCH with corresponding PDCCH). Here, PDSCH without corresponding PDCCH means that there is no PDCCH to directly schedule the PDSCH, such as the PDSCH in the SPS except for the initial PDSCH indicated by the SPS activation DCI. Here, the initial PDSCH refers to the first corresponding PDSCH after the SPS activation DCI. Therefore, since there is no directly corresponding PDCCH, the resource indication of the first feedback signal cannot be directly provided by the PDCCH, then the resource can be the uplink resource corresponding to an SPS PDSCH reception in the above-mentioned first set, or it can also be the uplink resource in the second set. The uplink resource in the second set can be related to the size of the HARQ-ACK information corresponding to the SPS PDSCH reception in the aforementioned first set, and the specific method will be described below.

[0120] In an embodiment of the present application, in at least one embodiment of operation 502, the terminal device may use a first uplink resource to send the above-mentioned first feedback signal, and the first uplink resource may be an uplink resource configured corresponding to an SPS PDSCH reception in the above-mentioned first set.

[0121] For example, the SPS PDSCH reception corresponding to the first uplink resource can be the SPS PDSCH reception with the largest or smallest SPS configuration ID corresponding to the SPSPDSCH reception in the first set. Assume that the PUCCH resource for HARQ-ACK feedback corresponding to the SPSPDSCH#m in the first set is PUCCH m , and the SPS configuration ID corresponding to SPS PDSCH#m is SPS m , the terminal device can use PUCCH i Sending the first feedback signal, wherein or

[0122] For another example, the SPS PDSCH reception corresponding to the first uplink resource can be the SPS PDSCH reception with the earliest or latest PDSCH start time domain position or end time domain position corresponding to the SPS PDSCH reception in the first set. Assume that the PUCCH resource for HARQ-ACK feedback corresponding to the SPS PDSCH#m in the first set is PUCCH m In addition, the PDSCH starting time domain position (symbol / time slot / sub-time slot) corresponding to SPS PDSCH#m is The terminal device can then use PUCCH i Send a first feedback signal, wherein or

[0123] For another example, the SPS PDSCH reception corresponding to the first uplink resource can be the SPS PDSCH reception with the earliest or latest start time domain position or end time domain position of the configured HARQ PUCCH resource corresponding to the SPS PDSCH reception in the first set. Assume that the configured PUCCH resource for HARQ-ACK feedback corresponding to SPS PDSCH#m in the first set is PUCCH m (For example, it is the PUCCH resource indicated by the HARQ PUCCH resource indication IE: n1PUCCH-AN in the corresponding SPS configuration SPS-config). m The starting time domain position (symbol / time slot / sub-time slot) of is The terminal device can then use PUCCH i Send a first feedback signal, wherein or

[0124] For another example, the SPS PDSCH reception corresponding to the first uplink resource can be an SPS PDSCH reception whose PUCCH corresponding to the SPS PDSCH reception in the first set meets the predefined timeline. Assume that the PUCCH resource for HARQ-ACK feedback corresponding to the SPS PDSCH#m in the first set is PUCCH m In addition, the end domain position (symbol / time slot / sub-time slot) of PDSCH corresponding to SPSPDSCH#m is In addition, the starting time domain position (symbol / time slot / sub-time slot) of the PUCCH corresponding to SPS PDSCH#m for carrying the corresponding HARQ-ACK information is when The terminal device can use PUCCH i Send a first feedback signal. Wherein, T is a predefined threshold, for example, the same as the N2 timeline, that is, equivalent to the minimum time domain interval between PDSCH transmission and corresponding HARQ-ACK feedback, which is related to the UE's reported capabilities and / or the (corresponding uplink) subcarrier spacing (SCS).

[0125] For another example, the SPS PDSCH reception corresponding to the first uplink resource may be an SPS PDSCH reception whose PUCCH capacity corresponding to the SPS PDSCH reception in the first set is greater than or equal to the corresponding total payload size. Assume that the PUCCH resource for HARQ-ACK feedback corresponding to the SPS PDSCH#m in the first set is PUCCH m In addition, the number of HARQ information bits corresponding to SPS PDSCH#m is N m In addition, the capacity of the PUCCH corresponding to SPS PDSCH#m for carrying the corresponding HARQ-ACK information is C m ,when The terminal device can use PUCCH i A first feedback signal is sent.

[0126] In this example, if there is no PUCCH with a capacity greater than or equal to the total load size, the terminal device can send the first feedback signal based on the PUCCH resource with the largest capacity. That is, the SPS PDSCH reception corresponding to the first uplink resource can be the SPS PDSCH reception in the first set with the largest PUCCH capacity. That is, if the SPS PDSCH in the first set does not have a corresponding PUCCH that meets the above conditions m , the terminal device can use PUCCH i’ Send a first feedback signal, wherein

[0127] In the embodiment of the present application, the capacity of the above-mentioned PUCCH is related to the time-frequency domain resource size, modulation mode, and / or code rate of the PUCCH resource, but the present application is not limited thereto.

[0128] In an embodiment of the present application, in at least one embodiment of operation 502, the terminal device may use (or based on) a second uplink resource to send the above-mentioned first feedback signal, and the second uplink resource belongs to a second set, and the second uplink resource is related to the size of the HARQ-ACK information corresponding to the SPS PDSCH reception in the first set.

[0129] Taking the second uplink resource as a PUCCH resource as an example, the second set may include {PUCCH#1, PUCCH#2, ..., PUCCH#K}, where one element is denoted as PUCCH#k, k=1, 2, 3, ..., K, (K>=1). Furthermore, for example, the uplink resources in the second set may be arranged in ascending or descending order according to resource capacity.

[0130] For example, assuming that the number of HARQ feedback bits corresponding to SPS PDSCH#m in the first set is N m In addition, the PUCCH resource capacity corresponding to PUCCH#k is C k ,when The terminal device can use PUCCH i If there is no PUCCH resource that meets the above conditions in the second set, the terminal device can send the first feedback signal according to the PUCCH k’ Sending a first feedback signal, wherein

[0131] For another example, assume that the payload size ranges corresponding to the second set {PUCCH#1, PUCCH#2, ..., PUCCH#K} are PUCCH#1→{P0, P1}, PUCCH#2→{P1, P2}, ..., PUCCH#K→{P K-1, P K}.when When the terminal device can use PUCCH k’ Send the first feedback signal. If there is no PUCCH that meets the above conditions k’ , then the terminal device according to PUCCH k” Sending a first feedback signal, wherein

[0132] In an embodiment of the present application, the above-mentioned second uplink resource can be indicated by RRC signaling, that is, the terminal device can use the above-mentioned second uplink resource to send the first feedback signal according to the RRC signaling. The RRC signaling is to instruct the terminal device to use the uplink resources in the second set to transmit the HARQ-ACK information corresponding to the SPS PDSCH reception in the first set. For example, the IE name of the RRC signaling is 'SPS-HARQ-multiplexing-PUCCH', which can be configured to be enabled (enable) or disabled (disabled) or not configured (for example, not being configured is equivalent to disabling). Under the condition that the RRC is enabled, the terminal device can transmit the HARQ information corresponding to the SPS PDSCH reception in the first set according to the uplink resources in the second set; if the indication of the RRC signaling is disabling, the terminal device needs to send the first feedback signal according to the HARQ PUCCH resource corresponding to the SPS PDSCH reception, and the specific implementation method is as described above.

[0133] In an embodiment of the present application, in at least one embodiment of operation 502, the terminal device may send a first feedback signal according to RRC signaling. For example, the enable status of the RRC signaling indicates that the terminal device allows the feedback information corresponding to at least two SPS PDSCHs on the same BWP to be multiplexed in the same uplink resource. For example, the IE name of the RRC signaling is 'SPS-HARQ-multiplexing', which can be configured to be enabled or disabled or not configured (for example, not being configured is equivalent to being disabled). That is, when the RRC signaling indicates the corresponding enable status, the terminal device can send the first feedback signal; if it is disabled (or not configured), the terminal device cannot send the first feedback signal.

[0134] In an embodiment of the present application, in at least one embodiment of operation 502, the terminal device may send a first feedback signal based on a reported terminal device capability (UE capability). The capability means that the terminal device is able to multiplex the feedback information corresponding to at least two SPS PDSCHs on the same BWP in the same uplink resource. The capability may be for all CCs / serving cells of the terminal device, or the capability may be reported separately by each CC / serving cell, and the present application is not limited thereto. When the terminal device has the capability and reports the corresponding information to the network device, the terminal device may send a first feedback signal according to the method described herein.

[0135] According to the above method of the embodiment of the present application, uplink resources (uplink signals) are selected to carry the above feedback information, so that the feedback information can be transmitted in uplink signals with appropriate time and frequency, ensuring the reliability of transmission, thereby improving system performance.

[0136] Through the method of the embodiment of the present application, the network device can more flexibly configure multiple SPSs in the same BWP / CC / serving cell / the same BWP of the same serving cell (more flexible period, starting position), and can also reduce the delay of SPS transmission feedback information.
