Description

Technical Field

[0001] This application belongs to the field of communication technology, specifically relating to a semi-persistent scheduling (SPS) physical downlink shared channel (PDSCH) receiving method, apparatus, user equipment, and medium. Background Technology

[0002] In NR R16, only unicast service transmission is allowed. User Equipment (UE) can only receive one or more unicast PDSCHs in a time unit (e.g., time slot). When there are multiple SPS PDSCHs in a time unit, if the time domain resources of multiple SPS PDSCHs overlap or exceed the UE's capacity, the UE will determine to receive a maximum of X SPS PDSCHs with non-overlapping time domain resources according to a predefined method (e.g., according to the configuration index of the SPS PDSCH), where X is the maximum number of PDSCHs that the UE can receive in a time slot.

[0003] In NR Release 17, broadcast / multicast services are supported. Service data is primarily transmitted via group-common PDSCH. Multicast SPS PDSCH is an important transmission method for multicast services. In Release 17, a UE can simultaneously configure / activate both multicast and unicast SPS PDSCH, with a maximum total of eight. With the introduction of multicast broadcast features, NR supports TDM transmission of unicast PDSCH and group-common PDSCH within a single time slot (i.e., transmission of different symbols within a single time slot), and also supports transmission of unicast PDSCH and group-common PDSCH on different frequency domain resources (i.e., Frequency Division Multiplexing, FDM transmission).

[0004] Therefore, determining the UE's reception behavior when multiple SPS PDSCHs exist within a single time unit is a problem that urgently needs to be solved. Summary of the Invention

[0027] The following will provide examples of the technical terms involved in the technical solutions provided in the embodiments of this application.

[0028] 1) PDSCH receiving capability

[0029] In NR, a UE can receive more than one unicast PDSCH in a single time slot, depending on its capabilities. For example, two, four, or seven PDSCHs. However, these PDSCHs need to be transmitted on different symbols (i.e., Time Division Multiplexing (TDM) transmission). With the introduction of multicast broadcast features, NR supports the transmission of unicast PDSCHs and group common PDSCHs on different symbols within a single time slot (i.e., TDM transmission), and also supports the transmission of unicast PDSCHs and group common PDSCHs on different frequency domain resources (i.e., Frequency Division Multiplexing (FDM) transmission).

[0030] 2) NR R17 MBS service transmission

[0031] Currently, NR technology has evolved through two versions, Rel-15 and Rel-16. Neither of these versions supported broadcast and / or multicast features. However, in many important use cases (e.g., public safety and mission critical, V2X applications, transparent IPv4 / IPv6 multicast delivery, IPTV, software delivery over wireless, group communications and IoT applications), broadcast and / or multicast features can provide substantial improvements, especially in system efficiency and user experience. Therefore, in the upcoming Rel-17 version, NR will introduce broadcast / multicast features.

[0032] Multicast SPS PDSCH is an important transmission method for multicast services. In Release 17, a UE can configure and / or activate both multicast SPS PDSCH and unicast SPS PDSCH simultaneously, with a total of no more than 8.

[0033] 3) PDSCH Conflict Handling

[0034] In NR R16, a serving cell can be configured with multiple SPS PDSCHs (up to 8). Within a time slot, time domain resources may overlap for multiple SPS PDSCHs, or the number of SPS PDSCHs may exceed the UE's receiving capacity. In this case, the UE receives X SPS PDSCHs with non-overlapping time domain resources according to a predefined priority order, where X is the maximum number of PDSCHs the UE can receive within a time slot.

[0035] Therefore, when a UE supports receiving frequency division multiplexing unicast PDSCH and multicast PDSCH within a time unit, and when there are multiple SPS PDSCHs within a time unit, how to determine the UE's receiving behavior is an urgent problem to be solved.

[0036] In the SPS PDSCH receiving method, apparatus, UE, and medium provided in the embodiments of this application, when the UE configures and activates multiple SPS PDSCHs on a serving cell, and the number of SPS PDSCHs configured and activated for reception by the UE within a certain time unit is greater than 1, the UE can determine which SPS PDSCHs to receive based on at least one of the following: SPS PDSCH configuration index, PDSCH receiving capability, the number of SPS PDSCH types, and the frequency domain resource distribution of unicast SPS PDSCHs and multicast SPS PDSCHs among the multiple SPS PDSCHs, thereby improving the effectiveness of the communication system.

[0037] The SPS PDSCH receiving method, apparatus, UE, and medium provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0038] This application provides an SPS PDSCH receiving method, such as... Figure 2 As shown, the SPSPDSCH receiving method provided in this application embodiment may include the following steps 201 and 202:

[0039] Step 201: If there are at least two SPS PDSCHs in a time unit on a serving cell, the UE determines, based on the first information, to receive at least one of the at least two SPS PDSCHs.

[0040] In the embodiments of this application, the above-mentioned at least two SPS PDSCHs include at least one of the above-mentioned SPS PDSCHs.

[0041] In the embodiments of this application, the time unit includes at least one of the following: time slot, mini-slot, and sub-slot.

[0042] In this embodiment of the application, the first information mentioned above includes at least one of the following:

[0043] SPS PDSCH configuration index;

[0044] UE's PDSCH receiving capability;

[0045] Number of SPS PDSCH types;

[0046] The frequency domain resource distribution of at least two SPS PDSCHs, including unicast SPS PDSCH and multicast SPS PDSCH.

[0047] It is understood that the above-mentioned PDSCH reception capability is used to characterize the UE's ability to receive SPS PDSCH. For example, the maximum number of PDSCHs that the terminal can receive in a time slot (or in a time slot of a carrier / serving cell), and / or whether the UE can receive FDM unicast PDSCH and multicast PDSCH.

[0048] It is understandable that the frequency domain resource distribution of unicast SPS PDSCH and multicast SPS PDSCH in the aforementioned at least two SPS PDSCHs can also be interpreted as whether there are unicast SPS PDSCHs and multicast SPS PDSCHs with different frequency domain resources among the aforementioned at least two SPS PDSCHs. In other words, the UE can determine whether there are unicast SPS PDSCHs and multicast SPS PDSCHs with different frequency domain resources among the aforementioned at least two SPS PDSCHs based on the frequency domain resource distribution of unicast SPS PDSCHs and multicast SPS PDSCHs in the aforementioned at least two SPS PDSCHs.

[0049] Optionally, in this embodiment of the application, the step 201 above, "UE determines to receive at least one SPS PDSCH based on the first information," may include the following step 201a:

[0050] Step 201a: The UE determines, according to the first information, to receive at least one of the two SPS PDSCHs in the target manner.

[0051] In some possible embodiments, the above-mentioned objective method includes at least one of the following: a first method, a second method, and a third method, wherein:

[0052] The first method is: the UE determines that it will receive at most N first SPS PDSCHs;

[0053] The second method is: the UE determines that it will receive at most M second SPS PDSCHs and at most K third SPS PDSCHs;

[0054] The third method is: the UE determines to receive a first unicast SPS PDSCH and a first multicast SPS PDSCH transmitted in different frequency domains.

[0055] For example, N, M, and K are positive integers.

[0056] In one example, M equals N.

[0057] In one example, M = N-1.

[0058] In one example, M+K=N.

[0059] In one example, M+K = N+1.

[0060] In one example, K = 1.

[0061] It should be noted that in the two scenarios of M=N, K=1, or M=N-1, K=1, the above M second SPSPDSCHs are unicast SPS PDSCHs and the above K third SPS PDSCHs are multicast SPS PDSCHs.

[0062] For example, the time domains of the at most N first SPS PDSCHs do not overlap.

[0063] For example, the time domains of the at most M second SPS PDSCHs do not overlap; the time domains of the at most K third SPS PDSCHs do not overlap.

[0064] For example, the above-mentioned at most M second SPS PDSCHs satisfy the frequency division multiplexing transmission requirements; the above-mentioned at most K third SPS PDSCHs satisfy the frequency division multiplexing requirements. For example, each of the K third SPS PDSCHs is in a different frequency domain from the M second SPS PDSCHs; or, each of the K third SPS PDSCHs is in a different frequency domain from at least one second SPS PDSCH (and none of the K third SPS PDSCHs overlaps with any of the second SPS PDSCHs in time-frequency resources); or, each of the K third SPS PDSCHs is frequency-division multiplexed with at least one second SPS PDSCH; or, each of the K third SPS PDSCHs is on different resources from each of the second SPS PDSCHs (i.e., different time-domain and frequency-domain resources) (allowing the same time-domain resources or the same frequency-domain resources); or, on any time-domain symbol, there is at most one multicast SPS PDSCH and at most one unicast SPS PDSCH.

[0065] For example, such as Figure 3 As shown, Figure 3 Four examples are shown, in which:

[0066] In Example (case) 1, unicast SPS PDSCH1 and unicast SPS PDSCH2, and multicast SPS PDSCH4 and multicast SPS PDSCH3 are in the same frequency domain; unicast SPS PDSCH1 and multicast SPS PDSCH4, and unicast SPS PDSCH2 and multicast SPS PDSCH3 are in different time domains within the same time domain. That is, unicast SPS PDSCH 1 and multicast SPS PDSCH4 are frequency-division multiplexed; unicast SPS PDSCH 2 and multicast SPS PDSCH3 are frequency-division multiplexed.

[0067] In Example (case) 2, unicast SPS PDSCH1 and multicast SPS PDSCH2, and multicast SPS PDSCH4 and unicast SPS PDSCH3 are in the same frequency domain; unicast SPS PDSCH1 and multicast SPS PDSCH4, and multicast SPS PDSCH2 and unicast SPS PDSCH3 are in different time domains within the same time domain. That is, unicast SPS PDSCH1 and multicast SPS PDSCH4 are frequency-division multiplexed; unicast SPS PDSCH3 and multicast SPS PDSCH2 are frequency-division multiplexed.

[0068] In example (case) 3, unicast SPS PDSCH1 and unicast SPS PDSCH2, multicast SPSPDSCH4 and multicast SPS PDSCH3 are in the same frequency domain; unicast SPS PDSCH2 and multicast SPSPDSCH3 are in different frequency domains in the same time domain; unicast SPS PDSCH1 and multicast SPS PDSCH4 partially overlap in the frequency domain.

[0069] In example (case)4, unicast SPS PDSCH1, unicast SPS PDSCH2, and multicast SPS PDSCH4 are in the same frequency domain; unicast SPS PDSCH2 and multicast SPS PDSCH3 are in the same time domain.

[0070] It should be noted that in the examples above, there is at most one multicast SPSPDSCH and at most one unicast SPS PDSCH on any time-domain symbol.

[0071] It is worth noting that the frequency division multiplexing requirement in this invention may include at least one of the following:

[0072] In a time slot of a serving cell, there is at most one unicast PDSCH and one multicast PDSCH, and the frequency domain resources of the unicast PDSCH and multicast PDSCH do not overlap (i.e., they are in different frequency domains).

[0073] In a time slot of a serving cell, there are at most A unicast PDSCHs and one multicast PDSCH, and the frequency domain resources of the multicast PDSCH and any unicast PDSCH do not overlap (i.e., they are in different frequency domains), where A is a positive integer greater than or equal to 1.

[0074] In a time slot of a serving cell, there are at most A unicast PDSCHs and one multicast PDSCH, and the frequency domain resources of the multicast PDSCH and any unicast PDSCH do not overlap (i.e., in different frequency domains), and the multicast PDSCH cannot overlap with the time domain resources of more than one unicast PDSCH, where A is a positive integer greater than or equal to 1.

[0075] In a single time slot of a serving cell, there are at most A unicast PDSCHs and B multicast PDSCHs. Furthermore, in any given time-domain symbol, there is at most one multicast SPS PDSCH and at most one unicast SPS PDSCH, and the multicast PDSCHs cannot overlap with any unicast PDSCH in the time-frequency domain (i.e., both the time and frequency domains overlap). Here, A and B are positive integers greater than or equal to 1.

[0076] In a time slot of a serving cell, there are at most A unicast PDSCHs and B multicast PDSCHs. The multicast PDSCHs cannot overlap with any unicast PDSCH in the frequency domain, and the multicast PDSCHs cannot overlap with more than one unicast PDSCH in the time domain. Here, A and B are positive integers greater than or equal to 1.

[0077] For example, N is the maximum number of PDSCHs that the UE can receive within a time unit. For example, N is equal to 1, 2, 4, or 7.

[0078] For example, the second SPS PDSCH is a unicast SPS PDSCH; the third SPS PDSCH is a multicast SPS PDSCH; or, the second SPS PDSCH is a multicast SPS PDSCH; the third SPS PDSCH is a unicast SPS PDSCH.

[0079] For example, the third approach described above can also be understood as: the UE determines to receive a first unicast SPS PDSCH and a first multicast SPS PDSCH that meet FDM requirements (e.g., in different frequency domain resources).

[0080] Regarding the first method:

[0081] In one possible example, the UE can first select the SPS PDSCH with the lowest SPS PDSCH configuration index from all SPS PDSCHs in the time unit and determine whether to receive that SPS PDSCH. Then, it can exclude that SPS PDSCH from all SPSPDSCHs and exclude SPSPDSCHs whose time domain overlaps with the selected SPS PDSCH. This process is repeated until the number of selectable SPS PDSCHs is 0 or the number of selected SPS PDSCHs equals N. Further, the specific operation may include the following steps:

[0082] Step 0: Set j = 0, where j represents the number of SPS PDSCHs selected for decoding.

[0083] Step 1: The UE receives the PDSCH with the lowest configured SPS configuration index (sps-ConfigIndex) within set Q. Then, it sets j = j + 1 and specifies that the received SPS PDSCH is the surviving SPS PDSCH.

[0084] Here, set Q is the set of active SPS PDSCHs within this time slot (i.e., all SPS PDSCHs in this time unit).

[0085] Step 2: Remove from set Q any PDSCHs that survived from step 1, as well as any SPS PDSCHs that overlap with the time-domain resources of the PDSCHs that survived from step 1 (including partial overlap and full overlap, e.g., overlap of time-domain resources, or overlap of both time-domain and frequency-domain resources).

[0086] Step 3: Repeat Step 1 and Step 2 until set Q is empty or j equals N.

[0087] Regarding the second method:

[0088] In one possible embodiment, the UE can determine at most M second SPS PDSCHs that do not overlap in the time domain and at most K third SPS PDSCHs that do not overlap in the time domain, based on the SPS PDSCH configuration index, wherein the M second SPS PDSCHs and the third SPS PDSCHs satisfy the FDM requirements.

[0089] For example, the above-mentioned at most M second SPS PDSCHs and the above-mentioned at most K third SPS PDSCHs belong to different types (i.e. different casts). That is, if the former is a unicast SPS PDSCH, then the latter is a multicast SPS PDSCH; or, if the former is a multicast SPS PDSCH, then the latter is a unicast SPS PDSCH.

[0090] For example, the M second SPS PDSCHs and the K third SPS PDSCHs satisfy the FDM requirements, such as that any one of the M second SPS PDSCHs cannot overlap with any one of the K third SPS PDSCHs in the time-frequency domain resources. Alternatively, any one of the M second SPS PDSCHs cannot be on the same frequency domain resources as any one of the K third SPS PDSCHs.

[0091] In one possible approach, the UE determines M non-overlapping unicast SPS PDSCHs from all unicast SPS PDSCHs in the time slot, according to the first approach described above. Then, it selects K multicast SPS PDSCHs from all multicast SPS PDSCHs in the time slot that have the lowest sps-configIndex and satisfy the FDM requirements with the aforementioned M unicast SPS PDSCHs.

[0092] For example, the UE first selects the SPS PDSCH with the lowest sps-ConfigIndex among all multicast SPS PDSCHs in the time slot, and determines whether this SPS PDSCH meets the FDM requirements with the M unicast PDSCHs. If it meets the requirements, the UE decides to receive this SPS PDSCH; otherwise, it does not receive it. Then, the UE selects the SPS PDSCH with the second lowest sps-ConfigIndex among all multicast SPS PDSCHs in the time slot, and determines whether this SPS PDSCH meets the FDM requirements with the M unicast PDSCHs and whether its time domain overlaps with the previously determined multicast SPS PDSCH. If it meets the FDM requirements and its time domain does not overlap, the UE decides to receive this SPS PDSCH; otherwise, it does not receive it. This process continues until K multicast SPS PDSCHs are selected or all multicast SPS PDSCHs in the time slot have been evaluated.

[0093] In another possible approach, the UE determines M non-overlapping unicast SPS PDSCHs from all unicast SPS PDSCHs in the time slot according to the first approach described above. Then, it selects K non-overlapping multicast SPS PDSCHs from all multicast SPS PDSCHs in the time slot according to the first approach described above. Then, for each of the K multicast SPS PDSCHs, it determines whether it meets the FDM requirements of the M unicast SPS PDSCHs. If any of them does not meet the FDM requirements, the multicast SPS PDSCH is not received.

[0094] Regarding the third method:

[0095] In one possible approach, the UE selects the SPS PDSCH with the lowest sps-ConfigIndex and determines to receive that SPS PDSCH. The UE then selects an SPS PDSCH of a different frequency domain and type than that SPS PDSCH.

[0096] In another possible approach, the UE selects the SPS PDSCH with the lowest sps-ConfigIndex from all unicast SPS PDSCHs in the time unit, and selects the SPS PDSCH with the lowest sps-ConfigIndex from all multicast SPS PDSCHs in the time unit. If the two SPS PDSCHs are in different frequency domains, the UE receives both SPS PDSCHs.

[0097] In another possible approach, the UE selects the SPS PDSCH with the lowest sps-ConfigIndex from all unicast SPS PDSCHs in the time unit, and then selects the multicast SPS PDSCH with the lowest sps-ConfigIndex from all multicast SPS PDSCHs in the time unit that is in a different frequency domain from the selected SPS PDSCH.

[0098] Optionally, in this embodiment of the application, after step 201 above, the technical solution provided by this embodiment of the application may further include the following step 202:

[0099] Step 202: The UE provides a Hybrid Automatic Repeat Request Acknowledgment (HARQ-ACK) response to the received SPS PDSCH.

[0100] Thus, when a UE configures and activates multiple SPS PDSCHs on a serving cell, and the number of SPS PDSCHs configured and activated for reception by the UE within a certain time unit is greater than one, the UE can use appropriate methods to determine which SPS PDSCHs to receive. It can then provide corresponding HARQ-ACK feedback for these PDSCHs, while not receiving or providing HARQ-ACK feedback for the remaining SPS PDSCHs, thereby improving the effectiveness of the communication system.

[0101] In some possible embodiments, step 201 above, "UE determines to receive at least one SPS PDSCH based on the first information," may include step 201b as follows:

[0102] Step 201b: If the first condition is met, the UE determines to receive at least one SPS PDSCH from the at least two SPS PDSCHs according to the first method; otherwise, the UE determines to receive at least one SPS PDSCH from the at least two SPS PDSCHs according to the second method or the third method.

[0103] For example, the first condition mentioned above includes at least one of the following:

[0104] The UE does not have the ability to receive frequency division multiplexing unicast PDSCH and multicast PDSCH;

[0105] The UE does not have the ability to indicate the reception of frequency division multiplexed unicast PDSCH and multicast PDSCH;

[0106] The UE was not instructed to receive frequency division multiplexed unicast PDSCH and multicast PDSCH;

[0107] No multicast SPS PDSCH within a time unit;

[0108] There are no unicast SPS PDSCH and multicast SPS PDSCH transmitted in different frequency domains within a time unit;

[0109] Within a time unit, there is either only unicast SPS PDSCH or only multicast SPS PDSCH;

[0110] Within a time unit, there is no PDSCH that is transmitted in a different frequency domain from the SPS PDSCH with the lowest configuration index;

[0111] Within a time unit, there are no SPS PDSCHs of different types that are transmitted in different frequency domains and have the lowest configuration index;

[0112] There is no multicast SPS PDSCH that is transmitted in a different frequency domain than the unicast SPS PDSCH with the lowest configuration index within a time unit.

[0113] In one possible example, when the UE is able to receive FDMed unicast PDSCH and multicast PDSCH in a time unit (e.g., each time slot on a carrier), or when the UE indicates that it will receive FDMed unicast PDSCH and multicast PDSCH, if there is no multicast SPS PDSCH in that time unit (e.g., slot) (or there is no multicast SPS PDSCH transmitted in a different frequency domain than the unicast SPS PDSCH, or the configuration index of all multicast SPS PDSCHs is greater than the configuration index of the unicast SPS PDSCH), the UE determines which SPS PDSCH to receive in a first manner and provides corresponding HARQ-ACK feedback for the received SPS PDSCH; otherwise, the UE determines that it will receive one unicast SPS PDSCH and one multicast PDSCH that meet the FDM requirements (e.g., one unicast SPS PDSCH and one multicast PDSCH in different frequency domain resources).

[0114] In one possible example, if the UE is capable of receiving FDMed unicast PDSCH and multicast PDSCH within a time unit (e.g., each time slot on a carrier), the UE determines which SPS PDSCH to receive according to either the second or third method, or if the UE is configured to receive FDM PDSCH (e.g., fdmed-Reception-Multicast), i.e., the UE determines which SPS PDSCH to receive according to the second or third method, and provides corresponding HARQ-ACK feedback for the received SPS PDSCH. Otherwise (i.e., no FDMed unicast PDSCH and multicast PDSCH capability, or no FDMPDSCH reception configured), the UE determines which SPS PDSCH to receive according to the first method, and provides corresponding HARQ-ACK feedback for the received SPS PDSCH.

[0115] The technical solutions provided in the embodiments of this application will be illustrated by specific examples below.

[0116] For example, when a UE supports receiving an FDMed unicast SPS PDSCH and a multicast SPS PDSCH on a carrier (or a component carrier or a serving cell), if there are at least two SPS PDSCHs in the previous time slot of a certain serving cell (the SPS PDSCH may be an SPS PDSCH after conflict resolution with a semi-static uplink symbol), the UE determines the received SPS PDSCH in the following manner and provides HARQ-ACK feedback for these determined SPS PDSCHs, and does not provide HARQ-ACK feedback for SPS PDSCHs that are not determined to be received.

[0117] In one example, if the UE can receive FDMed unicast PDSCH and multicast PDSCH in each time slot on a carrier, the UE determines which SPS PDSCH to receive according to the second method, or if the UE is configured to receive FDM PDSCH (e.g., fdmed-Reception-Multicast), that is, the UE determines which SPS PDSCH to receive according to the second method and provides corresponding HARQ-ACK feedback for the SPS PDSCH received by the UE. Otherwise (i.e., there is no FDMed unicast PDSCH and multicast PDSCH capability, or the UE is not configured to receive FDM PDSCH), the UE determines which SPS PDSCH to receive according to the first method and provides corresponding HARQ-ACK feedback for the SPS PDSCH received by the UE.

[0118] It should be noted that when providing HARQ-ACK feedback for the SPS PDSCH received by the UE, the feedback method can be determined based on the HARQ-ACK feedback method corresponding to each SPS PDSCH. For example, there may be ACK / NACK feedback, NACK only feedback, or no feedback required, etc.

[0119] Example 1: For the second approach, the UE determines at most M non-overlapping unicast SPS PDSCHs and one multicast SPS PDSCH that meets FDM requirements (e.g., in different frequency domain resources) based on the SPS PDSCH configuration index. For example, following the method in Example 1, the UE determines M non-overlapping unicast SPS PDSCHs from all unicast SPS PDSCHs in the time slot. Then, from all multicasts in the time slot, it selects an SPS PDSCH with the lowest sps-configIndex that does not overlap with the frequency domain of the aforementioned M SPS PDSCHs.

[0120] For example, suppose a UE can receive a maximum of 4 PDSCHs in a time slot, i.e., N=4, and assume M=N-1 and K=1. For example, ... Figure 4 As shown, the UE first determines a maximum of M=3 non-overlapping unicast SPS PDSCHs from SPS PDSCH0, SPS PDSCH2, SPS PDSCH4, SPS PDSCH5, and SPS PDSCH6 according to the first method. The determined result is unicast SPS PDSCH0, unicast SPS PDSCH4, and unicast SPS PDSCH6. Then, from multicast SPS PDSCH1 and multicast SPS PDSCH3, it determines one SPS PDSCH that is in a different frequency domain from the three unicast SPS PDSCHs determined above, and has the lowest SPS PDSCH configuration index. Since multicast SPS PDSCH1 and unicast SPS PDSCH0 overlap in both time and frequency domains, and multicast SPS PDSCH3 and unicast SPS PDSCH6 are in different frequency domains, the UE determines to receive multicast SPS PDSCH3. In another approach, the multicast SPS PDSCH shares the same frequency domain resource as at least one unicast SPS PDSCH that is determined to be received. In this case, the UE in this embodiment determines not to receive the multicast PDSCH.

[0121] In another example, if the UE can receive FDMed unicast PDSCH and multicast PDSCH in each time slot on a carrier, the UE determines which SPS PDSCH to receive according to a third method, or if the UE is configured to receive FDM PDSCH (e.g., fdmed-Reception-Multicast), i.e., the UE determines which SPS PDSCH to receive according to the third method and provides corresponding HARQ-ACK feedback for the received SPS PDSCH. Otherwise (i.e., no FDMed unicast PDSCH and multicast PDSCH capability, or no FDM PDSCH reception configured), the UE determines which SPS PDSCH to receive according to the first method and provides corresponding HARQ-ACK feedback for the received SPS PDSCH.

[0122] Example 2: For the third method, if there is no multicast SPS PDSCH in the time slot (or no multicast SPS PDSCH transmitted in a different frequency domain than unicast, or the configuration index of all multicast SPS PDSCHs is greater than the configuration index of the unicast SPS PDSCH), then the UE determines which SPS PDSCHs to receive according to the first method and provides corresponding HARQ-ACK feedback for the received SPS PDSCHs. For example, such as... Figure 5 As shown, Figure 5 If slot n contains only unicast SPS PDSCH, then the UE determines to receive SPS PDSCH 0, SPS PDSCH4, and SPSPDSCH6 according to the first method.

[0123] Otherwise, the UE determines to receive one unicast SPS PDSCH and one multicast SPS PDSCH from FDMed.

[0124] Specifically, the UE can operate in the following two ways:

[0125] Specifically, the UE can perform the following operations:

[0126] Sub-mode 1: The UE selects the SPS PDSCH with the lowest sps-ConfigIndex and confirms that it will receive the SPS PDSCH. The UE then selects an SPS PDSCH with a different cast in a different frequency domain than the selected SPS PDSCH. If there are multiple SPS PDSCHs with different casts in different frequency domains than the selected SPS PDSCH, the UE selects the SPS PDSCH with the lowest sps-ConfigIndex and confirms that it will receive the selected SPS PDSCH. If there are no SPS PDSCHs with different casts in different frequency domains than the selected SPS PDSCH, the UE only receives the selected SPS PDSCH.

[0127] For example, such as Figure 5 As shown, in slot m, the UE first determines to receive SPS PDSCH0, and then selects an SPS PDSCH with a different frequency domain, a different cast, and the lowest configuration index, namely SPS PDSCH1.

[0128] Sub-method 2: The UE selects the SPS PDSCH with the lowest sps-ConfigIndex from all unicast SPS PDSCHs in the time slot, and selects the SPS PDSCH with the lowest sps-ConfigIndex from all multicast SPS PDSCHs in the time slot. If the two SPS PDSCHs are in different frequency domains, the UE receives both SPS PDSCHs; otherwise, the UE only receives the SPS PDSCH with the lower sps-ConfigIndex.

[0129] For example, such as Figure 5 As shown, in slot m, the UE first determines to receive SPS PDSCH0 and SPS PDSCH1 respectively. Since the frequency domain resources of the two are different, the UE determines to receive these two SPS PDSCHs.

[0130] It should be noted that, Figure 3 With Figure 5 In any of the attached figures, SPS PDSCH(m) refers to multicast SPSPDSCH. Figure 3 With Figure 5 In any of the attached figures, SPS PDSCH(u) refers to unicast SPS PDSCH.

[0131] In this embodiment of the application, when a UE configures and activates multiple SPS PDSCHs on a serving cell, and the number of SPS PDSCHs configured and activated for reception by the UE within a certain time unit is greater than 1, the UE can determine which SPS PDSCHs to receive based on at least one of the following: SPSPDSCH configuration index, PDSCH reception capability, number of SPS PDSCH types, and frequency domain resource distribution of unicast SPSPDSCHs and multicast SPS PDSCHs among the multiple SPS PDSCHs, thereby improving the effectiveness of the communication system.
