[0002] This disclosure relates to the field of communication technologies, and particularly to a method, apparatus, and related devices for determining candidate PDSCH reception timing.

Background Art

[0003] In the fifth-generation mobile communication (the 5 th Generation, 5G) New Radio (NR), the quasi-static Hybrid Automatic Repeat reQuest (HARQ) codebook needs to determine the length of the codebook based on the number of determined Physical Downlink Shared Channel (PDSCH) candidate reception timings.

[0004] In related technologies, the number of PDSCH candidate reception timings depends on the number of all downlink slots configured by the network side. The number of bits of the quasi-static HARQ codebook also depends on the number of PDSCH candidate reception timings. The resource overhead of the quasi-static HARQ codebook is large, resulting in high energy consumption during the interaction process between the network-side device and the terminal device, and large signaling overhead.

[Means for solving the problem]

[0006] To solve the above problem, this disclosure is implemented as follows.

[0007] In a first embodiment, an embodiment of the present disclosure provides a method for determining candidate PDSCH reception timing performed by a terminal, the method being: Determining the target time-domain resources, This includes determining the candidate PDSCH reception timing corresponding to the hybrid auto retransmission request response HARQ-ACK information based on the determined target time domain resource, The aforementioned target time domain resource is The network-side device instructs the terminal to use the first time domain resource, The network-side equipment transmits multicast traffic to a second time domain resource, The network-side equipment transmits broadcast messages to a third-time domain resource, It relates to a fourth time-domain resource corresponding to an unconfigured subcarrier interval, and at least one of the time-domain resources.

[0008] Selectively, the candidate PDSCH reception timing corresponding to the determined hybrid auto-retransmission request response HARQ-ACK information does not include time-domain resources related to the target time-domain resource.

[0009] Selectively, based on the determined target time-domain resource, the timing of candidate PDSCH reception corresponding to the hybrid auto-retransmission request response HARQ-ACK information can be determined.

Or, This includes removing row indices from a set of row indices allocated by PDSCH time domain resources that overlap with the target time domain resource, obtaining the remaining row indices allocated by PDSCH time domain resources, and determining a third set of candidate PDSCH reception timings corresponding to HARQ-ACK information based on the remaining row indices allocated by PDSCH time domain resources.

[0014] Selectively, the first message includes at least one of a system message, upper-layer signaling, and downlink control information (DCI).

[0027] To more clearly illustrate the technical solutions of the embodiments of this disclosure, the above briefly describes the drawings that are necessary for describing the embodiments of this disclosure. Obviously, the drawings in the above description are only a few embodiments of this disclosure, and those skilled in the art can obtain other drawings based on these without any creative effort.

[0028] The technical solutions in the embodiments of this disclosure will be described clearly and completely below with reference to the drawings of the embodiments of this disclosure. Clearly, the embodiments described are some embodiments of this disclosure, not all embodiments. All other embodiments obtained by a person skilled in the art without creative work based on the embodiments of this disclosure are within the scope of protection of this disclosure.

[0029] In the embodiments of this disclosure, terms such as “first,” “second,” etc., are not required to be used to describe a specific order or priority, but are used to distinguish similar objects. Furthermore, “including” and “having” and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or apparatus that includes a set of steps or units is not necessarily limited to those expressly listed, and may include those not expressly listed, or other steps or units specific to those processes, methods, products, or apparatus. Furthermore, as used in this disclosure, “and / or” means at least one of the connected objects, for example, A and / or B and / or C, and means including a distinct A, a distinct B, a distinct C, and seven cases in which both A and B exist, both B and C exist, both A and C exist, and A, B and C exist.

[0030] Figure 1 is a structural diagram of a network system to which embodiments of this disclosure may be applied. As shown in Figure 1, it includes a data transmitting device 11 and a data receiving device 12.

[0031] Here, communication is possible between the data transmitting device 11 and the data receiving device 12. The data transmitting device 11 sends ciphertext information (Ciphertext Block) to the data receiving device 12.

[0032] In actual application, the data transmitting device 11 may be a terminal (also called user equipment (UE)) and the data receiving device 12 may be a network-side device, or the data transmitting device 11 may be a network-side device and the data receiving device 12 may be a terminal, but is not limited to these.

[0033] The terminal may be a mobile phone, tablet (tablet personal computer), laptop computer, personal digital assistant (PDA), mobile internet device (MID), wearable device, or in-vehicle device. The network-side equipment may be a base station, access and mobility management function (AMF), relay, access point, or other network element.

[0034] The following describes the candidate PDSCH reception timing determination method according to the embodiments of this disclosure.

[0035] Figure 2 is a schematic flowchart of a candidate PDSCH reception timing determination method according to an embodiment of this disclosure. The candidate PDSCH reception timing determination method shown in Figure 2 can be executed by a terminal.

[0036] As shown in Figure 2, the candidate PDSCH reception timing determination method may include the following steps 201-202.

[0037] Step 201 determines the target time domain resources.

[0038] Here, the target time domain resource is The network-side device instructs the terminal to use the first time domain resource, The network-side equipment transmits multicast traffic to a second time domain resource, The network-side equipment transmits broadcast messages to a third-time domain resource, It relates to a fourth time-domain resource corresponding to an unconfigured subcarrier interval, and at least one of the time-domain resources.

[0039] Furthermore, the situation in which network-side equipment instructs the terminal can be understood as the situation in which network-side equipment notifies the terminal while preparing for sleep mode, allowing the network to conserve energy by going into sleep mode, taking its own energy-saving needs into consideration. Since the network does not perform any data task scheduling for the slots in which network-side equipment goes into sleep mode, the terminal does not need to provide feedback to the network-side equipment with a Hybrid Automatic Repeat reQuest (HARQ) codebook. In this way, not only is energy consumption from sending HARQ information by the terminal side saved, but energy consumption from receiving HARQ information by the network side is also saved, and the network-side equipment sends the sleep time and time-domain pattern (understood as the first time-domain resource mentioned above) to the terminal while preparing for sleep mode.

[0040] Furthermore, an unconfigured subcarrier interval should be understood as a subcarrier interval different from the subcarrier interval configured by the network-side equipment or the default subcarrier interval. If the target time-domain resource includes a fourth time-domain resource corresponding to an unconfigured subcarrier interval, the terminal can first obtain the subcarrier interval configured by the network-side equipment or the default subcarrier interval, then recognize the unconfigured subcarrier interval based on the network-side equipment's configured or default subcarrier interval, and then recognize the corresponding fourth time-domain resource. For business channels where some terminals support only one type of subcarrier interval, if the network transmits the terminal's unconfigured subcarrier interval over a portion of the time (i.e., the fourth time-domain resource), the terminal cannot receive business data and does not need to provide HARQ feedback.

[0041] For terminals that do not support multicast and / or broadcast operations, the network transmits multicast or broadcast operations over second-time domain resources or third-time domain resources, and these terminals do not need to receive multicast and / or broadcast operation data, nor do they need to perform HARQ feedback.

[0042] In step 202, based on the determined target time-domain resource, the timing for receiving candidate (Physical Downlink Shared Channel, PDSCH) information corresponding to Hybrid Automatic Repeat reQuest acknowledgement (HARQ-ACK) information is determined.

[0043] Furthermore, the candidate PDSCH reception timings corresponding to the determined HARQ-ACK information can be used to construct a quasi-static codebook.

[0044] In some embodiments, if the target time-domain resource includes a fourth time-domain resource corresponding to an unconfigured subcarrier interval, the terminal can directly exclude PDSCH time-domain resources corresponding to a subcarrier interval different from the subcarrier interval configured by the network-side equipment or the default subcarrier interval, based on the subcarrier interval configured by the network-side equipment or the default subcarrier interval.

[0045] For slots where the network side is asleep (first time domain resources), the network side does not perform any data task scheduling, so the terminal does not need to feed back mixed HARQ codebooks to the network side equipment. In this way, not only is the energy consumption of HARQ information transmission by the terminal side reduced, but the energy consumption of HARQ information reception by the network side is also reduced.

[0046] For business channels where some terminals support only one type of subcarrier interval, if the network transmits a subcarrier interval that is not configured for those terminals over a portion of the time (i.e., fourth time domain resources), the terminals will not be able to receive business data and will not need to provide HARQ feedback.

[0047] For terminals that do not support multicast and / or broadcast operations, the network transmits multicast or broadcast operations over second-time domain resources or third-time domain resources, and these terminals do not need to receive multicast and / or broadcast operation data, nor do they need to perform HARQ feedback.

[0048] As described above, based on the target time-domain resources, the number of candidate PDSCH reception timings corresponding to the determined HARQ-ACK information can be reduced, and the number of bits for codebook feedback can be further reduced, thereby saving network resources and lowering energy consumption and signaling overhead during the interaction process between network-side devices and terminal devices.

[0049] Selectively, the candidate PDSCH reception timing corresponding to the determined hybrid auto-retransmission request response HARQ-ACK information does not include time-domain resources related to the target time-domain resource.

[0050] As described above, the candidate PDSCH reception timing corresponding to the determined HARQ-ACK information may exclude other time-domain resources as appropriate when excluding time-domain resources associated with the target time-domain resource, and unlike the target time-domain resource, the other time-domain resources to be excluded may be determined during application according to actual demand, and the embodiments of this disclosure are not limited thereto.

[0051] Selectively, based on the determined target time-domain resource, the timing of candidate PDSCH reception corresponding to the hybrid auto-retransmission request response HARQ-ACK information can be determined. Based on the set of row indices allocated by the PDSCH time domain resource allocation, a first set of candidate PDSCH reception timings is determined, This includes removing candidate PDSCH reception timings that overlap with the target time-domain resource from the first set to obtain a second set of candidate PDSCH reception timings corresponding to HARQ-ACK information.

[0052] Here, the set of row indices resulting from the PDSCH time domain resource allocation is a PDSCH time domain resource table (hereinafter abbreviated as the first PDSCH table) that is pre-configured by the network-side device for the terminal, pre-defined by the protocol, or pre-configured by the terminal, and the first PDSCH table contains at least two rows of PDSCH time domain resources, each row of PDSCH time domain resources corresponds to one row index, and the first set can be obtained by calculating the candidate PDSCH reception timing for each row of PDSCH time domain resources.

[0053] Furthermore, before calculating the candidate PDSCH reception timing for each row's PDSCH time-domain resource, the terminal further removes the PDSCH time-domain resources for uplink (UL) transmission from the first PDSCH table based on the K1 value of each row's PDSCH time-domain resource to obtain the second PDSCH table (i.e., the PDSCH time-domain resource table after removing the UL slots), and then calculates the candidate PDSCH reception timing for each row's PDSCH time-domain resource in the second PDSCH table.

[0054] After obtaining the first set, the terminal can obtain a second set for codebook feedback by excluding candidate PDSCH reception timings that overlap with the target time-domain resource from the first set.

[0055] Selectively, based on the determined target time-domain resource, the timing of candidate PDSCH reception corresponding to the hybrid auto-retransmission request response HARQ-ACK information can be determined. From the set of row indices allocated by PDSCH time domain resources, remove the row indices allocated by PDSCH time domain resources that overlap with the target time domain resource, and obtain the remaining row indices allocated by PDSCH time domain resources. This includes determining a third set of candidate PDSCH reception timings corresponding to HARQ-ACK information based on the row index obtained by the allocation of the remaining PDSCH time domain resources.

[0056] As described above, in order to determine the candidate PDSCH reception timing corresponding to the HARQ-ACK information, first, row indexes resulting from PDSCH time domain resource allocations that overlap with the target time domain resource are removed from the first PDSCH table to obtain the third PDSCH table (corresponding to the row indexes resulting from the remaining PDSCH time domain resource allocations), and then the candidate PDSCH reception timings for the PDSCH time domain resources in each row of the third PDSCH table are calculated to obtain a third set for codebook feedback.

[0057] Furthermore, when removing row indexes in the first PDSCH table that are allocated to PDSCH time domain resources that overlap with the target time domain resource, it is also possible to delete row indexes allocated to PDSCH time domain resources corresponding to UL slots all at once. In this case, the PDSCH time domain resource of any row in the third PDSCH table will not overlap with the target time domain resource and will not correspond to an UL slot.

[0058] Furthermore, the second and third sets are the same set, and preferably the acquisition method for the third set (i.e., a method that first excludes row indexes from the first PDSCH table that overlap with the target time-domain resource allocation, and then determines the candidate PDSCH reception timing corresponding to the HARQ-ACK information based on row indexes that do not overlap with the target time-domain resource allocation) is applied to determine the candidate PDSCH reception timing corresponding to the HARQ-ACK information. Since the terminal does not receive any business data at these timings, this embodiment can reduce the overhead of the candidate PDSCH reception timing of the PDSCH time-domain resource and the overhead of the HARQ codebook, and further reduce the energy consumption and signaling overhead of the terminal and network-side equipment.

[0059] Selectively determining the target time domain resource is Receiving a first message transmitted from a network-side device, wherein the first message includes first instruction information for the target time-domain resource. This includes determining the target time-domain resource based on the first instruction information.

[0060] As described above, when network-side equipment does not need to feed back the HARQ codebook from the terminal, it generates a first message accompanied by first instruction information and transmits this first message downstream. This method eliminates the overlap with target time-domain resources when the terminal feeds back the HARQ codebook, thereby reducing the number of bits in the codebook feedback from the terminal and saving network resources.

[0061] Selectively, based on the determined target time-domain resource, the timing of candidate PDSCH reception corresponding to the hybrid auto-retransmission request response HARQ-ACK information can be determined. If the first time interval is less than the first time threshold, and / or if the second time interval is less than the second time threshold, the process includes determining a candidate PDSCH reception timing corresponding to the HARQ-ACK information based on the set of row indices allocated by the PDSCH time domain resource allocation. Here, the first time interval is the time interval between the first slot in which the terminal receives the first message and the terminal's current HARQ codebook feedback slot, and the second time interval is the time interval between the second slot corresponding to the target time domain resource and the terminal's current HARQ codebook feedback slot.

[0062] As described above, the method of configuring the first and second time thresholds prevents the decoding operation (used to determine the target time-domain resource) and / or exclusion operation (used to exclude PDSCH time-domain resources that overlap with the target time-domain resource) from taking too long, and ensures that the terminal's current HARQ codebook feedback operation is completed smoothly within a predetermined slot.

[0063] Here, if the first time interval is less than the first time threshold, it is explained that the terminal does not have enough time to decode the first instruction information in the first message during the current HARQ codebook operation. Therefore, during the current HARQ codebook operation, the terminal skips the step of eliminating physical downlink shared channel PDSCH time domain resources that overlap with the target time domain resource and directly determines the candidate PDSCH reception timing corresponding to the HARQ-ACK information based on the first PDSCH table.

[0064] If the second time interval is less than the second time threshold, the terminal explains that it does not have enough time to eliminate PDSCH time domain resources that overlap with the target time domain resource in the current HARQ codebook operation. Therefore, during the current HARQ codebook feedback operation, the terminal also skips the step of eliminating physical downlink shared channel PDSCH time domain resources that overlap with the target time domain resource and directly determines the candidate PDSCH reception timing corresponding to the HARQ-ACK information based on the first PDSCH table.

[0065] The first slot is faster than the second slot, and the second slot is faster than the terminal's current HARQ codebook feedback slot.

[0066] The terminal will, during the following HARQ codebook feedback operation, Based on the set of row indices allocated to the PDSCH time domain resource, a first set of candidate PDSCH reception timings can be determined. From this first set, candidate PDSCH reception timings that overlap with the target time domain resource can be excluded to obtain a second set of candidate PDSCH reception timings corresponding to the HARQ-ACK information. From the set of row indices allocated by PDSCH time domain resources, it is also possible to remove row indices allocated by PDSCH time domain resources that overlap with the target time domain resource, obtain the remaining row indices allocated by PDSCH time domain resources, and then determine a third set of candidate PDSCH reception timings corresponding to HARQ-ACK information based on the remaining row indices allocated by PDSCH time domain resources.

[0067] Here, the subsequent HARQ codebook feedback operation can be understood as an HARQ codebook feedback operation performed by the terminal after the current HARQ codebook feedback operation is completed and before the terminal receives a first message accompanied by first instruction information that is transmitted again from the network-side device, and this HARQ codebook feedback operation may occur once or two or more times.

[0068] The method may be further, If the first time interval is greater than or equal to the first time threshold, and the second time interval is greater than or equal to the second time threshold, Based on the set of row indices allocated to the PDSCH time domain resource, a first set of candidate PDSCH reception timings is determined, and from the first set, candidate PDSCH reception timings that overlap with the target time domain resource are excluded to obtain a second set of candidate PDSCH reception timings corresponding to the HARQ-ACK information. Or, This includes removing row indices from a set of row indices allocated by PDSCH time domain resources that overlap with the target time domain resource, obtaining the remaining row indices allocated by PDSCH time domain resources, and determining a third set of candidate PDSCH reception timings corresponding to HARQ-ACK information based on the remaining row indices allocated by PDSCH time domain resources.

[0069] As described above, if there is sufficient time to decode the first instruction information in the first message (meaning the first time interval is greater than or equal to the first time threshold), and sufficient time to eliminate PDSCH time domain resources that overlap with the target time domain resource, the terminal can achieve the objective of saving network resources by eliminating PDSCH time domain resources that overlap with the target time domain resource, thereby reducing the number of candidate PDSCH reception timings corresponding to the determined HARQ-ACK information, and further reducing the number of bits for codebook feedback.

[0070] Selectively, the first message includes at least one of the following: a system message, upper-layer signaling, and Downlink Control Information (DCI).

[0071] As described above, by configuring the first message to be at least one of a system message, upper-layer signaling, and DCI, the requirements for sending message down in complex scenarios are met, ensuring that network-side devices can smoothly complete the downlink operation for the first message.

[0072] Selectively, the first time-domain resource is, Time-domain resources not used for downlink reception, Time-domain resources for uplink transmission, Includes at least one of the following: a time-domain resource for sleep.

[0073] After selecting a candidate PDSCH reception timing corresponding to the hybrid auto retransmission request response HARQ-ACK information based on the determined target time-domain resource, the method further: This includes constructing HARQ information bits based on the candidate PDSCH reception timing corresponding to the HARQ-ACK information.

[0074] As described above, once the candidate PDSCH reception timing corresponding to the HARQ-ACK information is obtained, the HARQ information bits are constructed and the message feedback to the network-side device is completed.

[0075] Figure 3 is a schematic flowchart of another candidate PDSCH reception timing determination method according to an embodiment of this disclosure. The candidate PDSCH reception timing determination method shown in Figure 3 can be performed by network-side equipment.

[0076] As shown in Figure 3, the candidate PDSCH reception timing determination method may include the following step 301.

[0077] In step 301, the terminal is sent the first message to determine a target time domain resource based on the first message, and to determine a candidate PDSCH reception timing corresponding to the hybrid auto retransmission request response HARQ-ACK information based on the determined target time domain resource.

[0078] Here, the target time domain resource is The network-side device instructs the terminal to use the first time domain resource, The network-side equipment transmits multicast traffic to a second time domain resource, The network-side equipment transmits broadcast messages to a third-time domain resource, It relates to a fourth time-domain resource corresponding to an unconfigured subcarrier interval, and at least one of the time-domain resources.

[0079] Selectively, the candidate PDSCH reception timing corresponding to the determined hybrid auto-retransmission request response HARQ-ACK information does not include time-domain resources related to the target time-domain resource.

Therefore, you can refer to the relevant explanations in the above embodiment of the method and achieve the same beneficial effects. To avoid redundant explanations, the explanations are omitted here.
