Description

[0001] This document generally relates to wireless communication, specifically fifth-generation (5G) or sixth-generation (6G) communication.

[0002] In 5G and 6G communications, metaverse and multimodal services are expected to become killer applications, posing challenges to the air interface. These applications involve transmitting multiple modes with differentiated Quality of Service (QoS) requirements within a single User Equipment (UE), with some modes having more stringent QoS requirements than existing services. One of the urgent problems to be solved is how to efficiently handle the concurrent and real-time transmission of multiple service streams.

[0045] Figure 1 A schematic diagram illustrating data reception according to an embodiment of this disclosure is shown. For example... Figure 1As shown, the Physical Downlink Shared Channel (PDSCH) overlaps with another PDSCH in time. In some implementations, the UE does not expect to receive a PDSCH that overlaps with another PDSCH in time, for the HARQ process ID in the scheduling cell. In some implementations, the UE does not support receiving more than one overlapping PDSCH in a single time slot. In some embodiments of this disclosure, the UE may support receiving more than one PDSCH that overlaps in time within a single timeslot (e.g., from one or more base stations (BS) or gNBs (gNodeB)).

[0046] In some embodiments of this disclosure, the UE may support receiving more than one PDSCH that overlaps in time and frequency within a single time slot (e.g., from one or more base stations (BS) or gNBs (gNodeB)).

[0047] In some implementations, for the generation of the Type-1 HARQ-ACK codebook, when generating the candidate PDSCH receive set, the UE can discard some PDSCHs when they overlap. In some implementations, the UE generates HARQ-ACK bits based on the candidate PDSCH receive set.

[0048] In some implementations, for the generation of the Type-2 HARQ-ACK codebook, the UE generates the HARQ-ACK bits based on the Downlink Allocation Indicator (DAI) field of the DCI (Downlink Control Information) signaling.

[0049] In some implementations, for codebook generation, the UE does not support more than one overlapping PDSCH feedback in a single time slot.

[0050] In some embodiments of this disclosure, the UE may support more than one overlapping PDSCH feedback in a time slot.

[0051] In some embodiments of this disclosure, the UE can perform: Receive at least one of the data from the first resource or the data from the second resource; and First information is transmitted via a first signaling, the first information being associated with at least one of data reception in a first resource or data reception in a second resource.

[0052] In some implementations, a first control signaling directs a first resource.

[0053] In some implementations, a second resource is indicated by a second control signaling that is different from the first control signaling.

[0054] In some implementations, the first resource and the second resource are indicated by the same control signaling (e.g., a first control signaling or a second control signaling).

[0055] The following paragraphs describe several aspects of the embodiments disclosed herein, including: Control signaling; First and second resources; The receipt of the first and / or second resources; and First message and first signaling.

[0056] Aspect 1: Control Signaling In some implementations, the control signaling is at least one of the following: higher-layer parameters or downlink control information (DCI) signaling. Higher-layer parameters may be RRC signaling (e.g., configuration...). SPS-Config This can be either Media Access Control (MAC) Control Element (MCCE) signaling or DCI signaling. In some cases, DCI signaling is UE-specific DCI signaling. In other cases, DCI signaling is group-common DCI signaling.

[0057] In some implementations, the information carried by the control signaling includes at least one of resource information or configuration information. Resource information may include at least one of the following: 1. Time-domain resource indication In some implementations, a time-domain resource indicator is used to determine the start and length indicator (SLIV) value of the time domain of the first resource.

[0058] In some cases, SLIV indicates the starting symbol of the first resource, as well as the symbol length or number of symbols of the first resource.

[0059] In some implementations, a time-domain resource indicator is used to determine the start and length indicator (SLIV) value of the time domain of the second resource.

[0060] In some cases, SLIV indicates the starting symbol of the second resource, as well as the symbol length or number of symbols of the second resource.

[0061] In some implementations, the time-domain resource indicator is used to determine the time-domain SLIV of the first and second resources.

[0062] In some cases, each SLIV indicates the start symbol of a time slot and the symbol length or number of symbols in the time slot. One SLIV indicates the start symbol of a first resource and the symbol length or number of symbols in the first resource, while another SLIV includes the start symbol of a second resource and the symbol length or number of symbols in the second resource.

[0063] 2. Frequency domain resource indication In some implementations, a frequency domain resource indicator is used to determine a bitmap or resource indicator value (RIV) in the frequency domain of a first resource.

[0064] In some cases, a bitmap or RIV indicates the resource block of the first resource.

[0065] In some implementations, the frequency domain resource indicator is a bitmap or RIV used to determine the frequency domain of the second resource.

[0066] In some cases, a bitmap or RIV indicates a resource block of a second resource.

[0067] In some implementations, the frequency domain resource indicator is a bitmap or RIV used to determine the frequency domain of the first and second resources.

[0068] In some cases, each bitmap or RIV indicates the resource block occupancy of a resource. One bitmap or RIV indicates the resource block of a first resource, and another bitmap or RIV indicates the resource block of a second resource. 3. Modulation and Coding Scheme (MCS) Indication In some implementations, the MCS indicator is used to determine the MCS level of the first resource.

[0069] In some implementations, the MCS indicator is used to determine the MCS level of the second resource.

[0070] In some implementations, the MCS indicator is used to determine the MCS level of the first and second resources.

[0071] In some implementations, the configuration information for the control signaling bearer may include at least one of the following: Number of floors; Demodulation reference signaling mode; The same configuration information for both the first and second resources (in this case, the configuration information for the first resource and the configuration information for the second resource can be the same); and / or Different configuration information for the first resource and the second resource (in this case, the configuration information for the first resource is different from the configuration information for the second resource).

[0072] Second aspect: First and second resources In some implementations, the first resource includes one or more Physical Downlink Shared Channels (PDSCHs). In some cases, the one or more PDSCHs are dynamically licensed PDSCHs. In some cases, the one or more PDSCHs are semi-persistent PDSCHs. In some cases, the one or more PDSCHs reside within a Common Frequency Resource (CFR). In some cases, the one or more PDSCHs reside within a specific frequency resource. In some cases, one or more PDSCHs are high-priority PDSCHs.

[0073] As an alternative, data with stricter latency is transmitted in high-priority PDSCH.

[0074] In some implementations, the second resource includes one or more PDSCHs. In some cases, the one or more PDSCHs are dynamically licensed PDSCHs. In some cases, the one or more PDSCHs are semi-persistent PDSCHs. In some cases, the one or more PDSCHs reside within a common frequency resource (CFR).

[0075] In some cases, one or more PDSCHs are low-priority PDSCHs.

[0076] As an alternative, data with more relaxed latency is transmitted in low-priority PDSCH.

[0077] In some implementations, data for the first resource is transmitted using a first codeword, while data for the second resource is transmitted using a second codeword. In some cases, when the total number of layers is not greater than the threshold, the data of the first resource is transmitted with the first codeword, and the data of the second resource is transmitted with the second codeword. As an alternative, the threshold is 4.

[0078] In some cases, the number of layers of the first codeword is different from the number of layers of the second codeword. In some implementations, the layer number of the first codeword and the layer number of the second codeword are determined by DCI signaling.

[0079] In some implementations, the data transmitted in either a first or second codeword is determined by DCI signaling. In some cases, one or more fields in the DCI signaling are used for codeword switching.

[0080] Third aspect: Receiving the first and / or second resources In some implementations, the UE receives data from the first resource and data from the second resource in a multiplexed mode. In some implementations, the multiplexing mode satisfies the following condition: the time and frequency domains of the first resource overlap with the time and frequency domains of the second resource. In some cases, the overlap between the time and frequency domains of the first resource and the second resource may include: the time and frequency domains of the first resource being a subset of the time and frequency domains of the second resource, or the time and frequency domains of the second resource being a subset of the time and frequency domains of the first resource.

[0081] In some implementations, the MCS level of the first resource is different from that of the second resource. In some cases, the MCS level includes the modulation order of the resource and the code rate of the resource.

[0082] In some implementations, the first resource and the second resource correspond to the same HARQ process identifier. In some cases, the same HARQ process ID is assigned to both the first and second resources. Within a designated scheduling cell, the UE needs to receive the first resource, which overlaps in time with the second resource under the same HARQ process ID.

[0083] In some cases, the same HARQ process ID is assigned to both the first and second resources. Within a designated scheduling cell, the UE needs to receive the first resource, which overlaps with the second resource under the same HARQ process ID in time and frequency.

[0084] In some cases, different HARQ process IDs are assigned to the first resource and the second resource, respectively. Within a designated scheduling cell, the radio terminal (UE) needs to receive the first resource, which overlaps in time with the second resource under different HARQ process IDs.

[0085] In some cases, different HARQ process IDs are assigned to the first resource and the second resource, respectively. Within a designated scheduling cell, the radio terminal (UE) needs to receive the first resource, which overlaps with the second resource under different HARQ process IDs in time and frequency.

[0086] In some implementations, the first resource and the second resource are allocated to a wireless communication terminal.

[0087] In some implementations, the first and second resources are reused when a certain condition is met (for example, the first and second resources are resources in multiplexing mode).

[0088] In some cases, this condition is related to and The value is related to, where This indicates the time slot interval between the first scheduling DCI signaling and the first resource, and This indicates the time slot interval between the scheduling DCI signaling and the second resource.

[0089] As an alternative, when and The difference between them (the larger one minus the smaller one, for example) When the threshold is not greater than the specified threshold, the wireless terminal needs to receive the first and second resources in multiplexing mode. This threshold is determined by RRC signaling or UE capabilities.

[0090] As an alternative, when and When the difference between the two resources exceeds a threshold, the wireless terminal needs to receive the first and second resources in multiplexing mode. This threshold is determined by RRC signaling or UE capabilities.

[0091] As an alternative, when and When the maximum value in the range is not greater than the threshold, the wireless terminal needs to receive the first and second resources in multiplexing mode. This threshold is determined by RRC signaling or UE capabilities.

[0092] As an alternative, when and When the maximum value in the range exceeds the threshold, the wireless terminal needs to receive the first and second resources in multiplexing mode. This threshold is determined by RRC signaling or UE capabilities.

[0093] As an alternative, when and When the minimum value in the threshold is not greater than the threshold value, the wireless terminal needs to receive the first resource and the second resource in multiplexing mode. This threshold value is determined by RRC signaling or UE capability.

[0094] As an alternative, when and When the minimum value in the threshold is greater than the threshold, the wireless terminal needs to receive the first and second resources in multiplexing mode. This threshold is determined by RRC signaling or UE capabilities.

[0095] As an alternative, when and When both values ​​are not greater than the threshold, the wireless terminal needs to receive the first resource and the second resource in multiplexing mode. This threshold is determined by RRC signaling or UE capabilities.

[0096] As an alternative, when and When both values ​​exceed the threshold, the wireless terminal needs to receive the first and second resources in multiplexing mode. This threshold is determined by RRC signaling or UE capabilities.

[0097] In some cases, this condition is related to and The values ​​are related to the difference between them, where This indicates the PDCCH monitoring timing index for the first resource, and This indicates the PDCCH monitoring timing index for the second resource. As an alternative, when and The difference between them (the larger one minus the smaller one, for example) When the threshold is not greater than the specified threshold, the wireless terminal needs to receive the first and second resources in multiplexing mode. This threshold is determined by RRC signaling or UE capabilities.

[0098] In some cases, this condition is related to and The value is related to, where The time slot interval between the resource representing the first information (e.g., PUCCH or PUSCH) and the first resource, and The time slot interval between the resource containing the first information (e.g., PUCCH or PUSCH) and the second resource.

[0099] As an alternative, when and When the minimum value in the threshold is not greater than the threshold value, the wireless terminal needs to receive the first resource and the second resource in multiplexing mode. This threshold value is determined by RRC signaling or UE capability.

[0100] As an alternative, when and When the minimum value in the threshold is greater than the threshold, the wireless terminal needs to receive the first and second resources in multiplexing mode. This threshold is determined by RRC signaling or UE capabilities.

[0101] As an alternative, when and When the maximum value in the range is not greater than the threshold, the wireless terminal needs to receive the first and second resources in multiplexing mode. This threshold is determined by RRC signaling or UE capabilities.

[0102] As an alternative, when and When the maximum value in the range exceeds the threshold, the wireless terminal needs to receive the first and second resources in multiplexing mode. This threshold is determined by RRC signaling or UE capabilities.

[0103] As an alternative, when and When both values ​​are not greater than the threshold, the wireless terminal needs to receive the first resource and the second resource in multiplexing mode. This threshold is determined by RRC signaling or UE capabilities.

[0104] As an alternative, when and When both values ​​exceed the threshold, the wireless terminal needs to receive the first and second resources in multiplexing mode. This threshold is determined by RRC signaling or UE capabilities.

[0105] In some cases, this condition is related to the value of a first interval, where the first interval represents the interval between the last symbol of the PDCCH monitoring timing for the first resource and the first symbol of the second resource.

[0106] As an alternative, when the first interval is greater than a threshold, the wireless terminal needs to receive the first and second resources in multiplexing mode. This threshold is determined by RRC signaling or UE capabilities.

[0107] As an alternative, when the first interval is not greater than a threshold, the wireless terminal needs to receive the first and second resources in a multiplexed mode. This threshold is determined by RRC signaling or UE capabilities.

[0108] In some implementations, the threshold is an integer, and the unit of the threshold is a symbol, a time slot, or a microsecond.

[0109] For example, two methods for multiplexing multiple PDSCHs are defined. It is assumed that the first resource carries high-priority haptic data scheduled by the first DCI signaling (high-priority DCI signaling), while the second resource carries low-priority video data scheduled by the second DCI signaling (low-priority DCI signaling).

[0110] Method (1) (see) Figure 10 For the location of overlapping REs (or resources), the wireless terminal does not need to receive video data (i.e., video data in the second resource) (part of the PDSCH transmitted via the overlapping RE is discarded), but the wireless terminal needs to receive haptic data (i.e., haptic data in the first resource, PDSCH_haptic).

[0111] Method (2) (see) Figure 11 For the location of overlapping REs (or resources), the UE needs to receive PUSCH_haptic. In this case, part of the PDSCH will not be discarded, but the complete PDSCH will be mapped to resources other than the overlapping REs. If method (1) is used, since it is too late to perform rate matching of the complete PDSCH, part of the PDSCH may be discarded.

[0112] In one implementation, the wireless terminal follows a timeline requirement, namely the timeline between the second scheduling DCI (i.e., the low-priority scheduling DCI for video data), the start symbol of the second resource (i.e., the low-priority PDSCH carrying video data), and the first scheduling DCI (i.e., the high-priority scheduling DCI for haptic data). The UE performs method (1) or method (2) according to the timeline requirement. In some cases, when the time offset from the second scheduling DCI to the first scheduling DCI is greater than a threshold, the UE executes method (2), in which the gNB has enough time to schedule two PDSCHs that overlap in time.

[0113] In some cases, when the time offset is defined as the time from the start symbol of the second resource (i.e., the low-priority PDSCH carrying video data) to the first scheduling DCI (i.e., the high-priority scheduling DCI used for haptic data), As an alternative, the time offset Nt = the time point of the first DCI - the time point of the second DCI.

[0114] As an alternative, the time offset Nt = the time point of the starting symbol of the second resource - the time point of the first DCI.

[0115] Case 1: Nt = threshold (e.g., 0), that is, the time offset from the first DCI to the second DCI is 0, and the UE executes method (2) (see Figure 12 ). Case 2: Nt < threshold (e.g., 0), UE executes method (1). In this case, it is too late for gNB to schedule two PDSCHs that overlap in time. In addition, when transmitting the second DCI, gNB may have already transmitted several symbols of the first PDSCH, making it difficult to reschedule the first PDSCH (see Figure 13). In some cases, this condition is related to the RNTI (Radio Network Temporary Identifier) ​​type of the DCI signaling that schedules the first resource and the DCI signaling that schedules the second resource.

[0116] As an alternative, when the first and second resources are scheduled by DCI signaling scrambled by C-RNTI (Cell Radio Network Temporary Identifier) ​​or CS-RNTI (Configured Scheduling Radio Network Temporary Identifier), the wireless terminal needs to receive the first and second resources in multiplexing mode.

[0117] In some implementations, the UE receives data from a first resource and data from a second resource, where the first resource and the second resource are located in a first codeword and a second codeword, respectively. In some cases, the data in the first resource and the data in the second resource belong to the same UE.

[0118] In some implementations, wireless communication terminals are not required to receive more data than the maximum number of resources in a time slot. In one implementation, the number of multiplexed resources in multiplexing mode does not exceed the maximum number of resources in a time slot. In one implementation, the maximum number of resources in a time slot is determined by RRC signaling or UE capabilities.

[0119] In one implementation, the wireless communication terminal is not required to receive more PDSCHs than the maximum number of PDSCHs in the time slot.

[0120] For example, based on RRC signaling or UE capabilities, the maximum number of resources in a time slot is set to 3. The UE can (or needs to) receive data from 1, 2, or 3 resources in a time slot.

[0121] Fourth aspect: First information and first signaling In some implementations, the first information includes a Type-1 HARQ-ACK codebook, which includes HARQ-ACK information sequentially used for data in the first resource and data in the second resource.

[0122] In one implementation, the Type-1 HARQ-ACK codebook includes HARQ ACK information for data used sequentially for a first resource and data for a second resource, wherein the first resource and the second resource are in a multiplexed mode.

[0123] In one implementation, the order is based on the timing of the PDCCH monitoring index corresponding to the first and second resources. In some cases, the order is ascending.

[0124] In some cases, the order is descending.

[0125] In some cases, the index for PDCCH monitoring timing corresponds to the search space set index.

[0126] For example, in ascending order, the first resource is indexed by the search space set. The first scheduling is the DCI scheduling, while the second resource is indexed by the search space set. The second scheduling DCI scheduling. When In the HARQ-ACK information of the first and second resources in multiplexing mode, the first bit is used for the data in the first resource, and the second bit is used for the data in the second resource. More specifically, when the HARQ-ACK information is "11", it implies that the first bit "1" indicates successful reception of data in the first resource, and the second bit "1" indicates successful reception of data in the second resource.

[0127] For example, in descending order, the first resource is indexed by the search space set. The first scheduling is the DCI scheduling, while the second resource is indexed by the search space set. The second scheduling DCI scheduling. When In the HARQ-ACK information of the first and second resources in multiplexing mode, the first bit is used for the data in the second resource, and the second bit is used for the data in the first resource. More specifically, when the HARQ-ACK information is "11", it implies that the first bit "1" indicates successful reception of data in the second resource, and the second bit "1" indicates successful reception of data in the first resource.

[0128] In one implementation, the sequence is based on the starting symbol index of the PDCCH monitoring timing corresponding to the first and second resources.

[0129] In some cases, the order is ascending. In some cases, the order is descending.

[0130] For example, in ascending order, the first resource is scheduled by the first scheduler DCI, where the starting symbol index of the PDCCH monitoring timing is... The second resource is scheduled by the second scheduler DCI, where the starting symbol index of the PDCCH monitoring timing is... .when In the HARQ-ACK information of the first and second resources in multiplexing mode, the first bit is used for the data in the first resource, and the second bit is used for the data in the second resource. More specifically, when the HARQ-ACK information is "11", it implies that the first bit "1" indicates successful reception of data in the first resource, and the second bit "1" indicates successful reception of data in the second resource.

[0131] For example, in descending order, the first resource is scheduled by the first scheduler DCI, where the starting symbol index of the PDCCH monitoring timing is... The second resource is scheduled by the second scheduler DCI, where the starting symbol index of the PDCCH monitoring timing is... .when In the HARQ-ACK information of the first and second resources in multiplexing mode, the first bit is used for the data in the second resource, and the second bit is used for the data in the first resource. More specifically, when the HARQ-ACK information is "11", it implies that the first bit "1" indicates successful reception of data in the second resource, and the second bit "1" indicates successful reception of data in the first resource.

[0132] In one implementation, the sequence is based on the end symbol index of the PDCCH monitoring timing corresponding to the first and second resources. In some cases, the order is ascending. In some cases, the order is descending.

[0133] For example, in ascending order, the first resource is scheduled by the first scheduler DCI, where the end symbol index of the PDCCH monitoring timing is... The second resource is scheduled by the second scheduler DCI, where the end symbol index of the PDCCH monitoring timing is... .when In the HARQ-ACK information of the first and second resources in multiplexing mode, the first bit corresponds to the data in the first resource, and the second bit corresponds to the data in the second resource. More specifically, when the HARQ-ACK information is "11", it implies that the first bit "1" indicates successful reception of data in the first resource, and the second bit "1" indicates successful reception of data in the second resource.

[0134] For example, in descending order, the first resource is scheduled by the first scheduler DCI, where the end symbol index of the PDCCH monitoring timing is... The second resource is scheduled by the second scheduler DCI, where the end symbol index of the PDCCH monitoring timing is... .when In the HARQ-ACK information of the first and second resources in multiplexing mode, the first bit corresponds to the data in the second resource, and the second bit corresponds to the data in the first resource. More specifically, when the HARQ-ACK information is "11", it implies that the first bit "1" indicates successful reception of data in the second resource, and the second bit "1" indicates successful reception of data in the first resource.

[0135] In one implementation, the sequence is based on the starting position parameter within the SLIV corresponding to the first and second resources.

[0136] In some cases, the starting position parameter within the SLIV of the first resource is the starting symbol index of the first resource.

[0137] In some cases, the starting position parameter within the SLIV of the second resource is the starting symbol index of the second resource.

[0138] In some cases, the order is ascending.

[0139] In some cases, the order is descending.

[0140] For example, in ascending order, the starting position parameter of the first resource (e.g., the starting symbol index) is The starting position parameter of the second resource (e.g., the starting symbol index) is .when In the HARQ-ACK information of the first and second resources in multiplexing mode, the first bit corresponds to the data in the first resource, and the second bit corresponds to the data in the second resource. More specifically, when the HARQ-ACK information is "11", it implies that the first bit "1" indicates successful reception of data in the first resource, and the second bit "1" indicates successful reception of data in the second resource.

[0141] For example, in descending order, the starting position parameter of the first resource (e.g., the starting symbol index) is The starting position parameter of the second resource (e.g., the starting symbol index) is .when In the HARQ-ACK information of the first and second resources in multiplexing mode, the first bit corresponds to the data in the second resource, and the second bit corresponds to the data in the first resource. More specifically, when the HARQ-ACK information is "11", it implies that the first bit "1" indicates successful reception of data in the second resource, and the second bit "1" indicates successful reception of data in the first resource.

[0142] In one implementation, the order is based on a length parameter within the SLIV corresponding to the first and second resources. In some cases, the length parameter within the SLIV of the first resource is the number of consecutive symbols occupied by the first resource.

[0143] In some cases, the length parameter within the SLIV of the second resource is the number of consecutive symbols occupied by the second resource.

[0144] In some cases, the order is ascending.

[0145] In some cases, the order is descending.

[0146] For example, in ascending order, the length parameter of the first resource (e.g., the number of consecutive symbols) is The length parameter of the second resource (e.g., the number of consecutive symbols) is .when In the HARQ-ACK information of the first and second resources in multiplexing mode, the first bit corresponds to the data in the first resource, and the second bit corresponds to the data in the second resource. More specifically, when the HARQ-ACK information is "11", it implies that the first bit "1" indicates successful reception of data in the first resource, and the second bit "1" indicates successful reception of data in the second resource.

[0147] For example, in the case of descending order, the length parameter of the first resource (e.g., the number of consecutive symbols) is The length parameter of the second resource (e.g., the number of consecutive symbols) is .when In the HARQ-ACK information of the first and second resources in multiplexing mode, the first bit corresponds to the data in the second resource, and the second bit corresponds to the data in the first resource. More specifically, when the HARQ-ACK information is "11", it implies that the first bit "1" indicates successful reception of data in the second resource, and the second bit "1" indicates successful reception of data in the first resource.

[0148] In one implementation, the sequence is based on an end position parameter derived from the SLIV corresponding to the first and second resources.

[0149] In some cases, the end position parameter of the first resource is the end symbol index of the first resource.

[0150] In some cases, the end position parameter of the second resource is the end symbol index of the second resource.

[0151] In some cases, the end symbol index is derived from the start symbol index and the number of consecutive symbols within the SLIV.

[0152] In some cases, the order is ascending.

[0153] In some cases, the order is descending.

[0154] For example, in ascending order, the end position parameter of the first resource (e.g., the end symbol index) is The end position parameter of the second resource (e.g., the end symbol index) is .when In the HARQ-ACK information of the first and second resources in multiplexing mode, the first bit corresponds to the data in the first resource, and the second bit corresponds to the data in the second resource. More specifically, when the HARQ-ACK information is "11", it implies that the first bit "1" indicates successful reception of data in the first resource, and the second bit "1" indicates successful reception of data in the second resource.

[0155] For example, in descending order, the end position parameter of the first resource (e.g., the end symbol index) is The end position parameter of the second resource (e.g., the end symbol index) is .when In the HARQ-ACK information of the first and second resources in multiplexing mode, the first bit corresponds to the data in the second resource, and the second bit corresponds to the data in the first resource. More specifically, when the HARQ-ACK information is "11", it implies that the first bit "1" indicates successful reception of data in the second resource, and the second bit "1" indicates successful reception of data in the first resource.

[0156] In one implementation, the sequence is based on the starting position parameter within the RIV or bitmap corresponding to the first and second resources.

[0157] In some cases, the starting position parameter within the RIV or bitmap of the first resource is the starting resource block index of the first resource.

[0158] In some cases, the starting position parameter within the RIV or bitmap of the second resource is the starting resource block index of the second resource.

[0159] In some cases, the order is ascending.

[0160] In some cases, the order is descending.

[0161] For example, in ascending order, the starting position parameter of the first resource (e.g., the starting resource block index) is The starting position parameter of the second resource (e.g., the starting resource block index) is .when In the HARQ-ACK information of the first and second resources in multiplexing mode, the first bit corresponds to the data in the first resource, and the second bit corresponds to the data in the second resource. More specifically, when the HARQ-ACK information is "11", it implies that the first bit "1" indicates successful reception of data in the first resource, and the second bit "1" indicates successful reception of data in the second resource.

[0162] For example, in descending order, the starting position parameter of the first resource (e.g., the starting resource block index) is The starting position parameter of the second resource (e.g., the starting resource block index) is .when In the HARQ-ACK information of the first and second resources in multiplexing mode, the first bit corresponds to the data in the second resource, and the second bit corresponds to the data in the first resource. More specifically, when the HARQ-ACK information is "11", it implies that the first bit "1" indicates successful reception of data in the second resource, and the second bit "1" indicates successful reception of data in the first resource.

[0163] In one embodiment, the order is based on the length parameter within the RIV or bitmap corresponding to the frequency domain indication of the first and second resources. In some cases, the length parameter within the RIV or bitmap of the first resource is the number of resource blocks occupied by the first resource.

[0164] In some cases, the length parameter within the RIV or bitmap of the second resource is the number of resource blocks occupied by the second resource.

[0165] In some cases, the number of resource blocks can be determined from the bitmap indication by counting the number of bit 1s in the bitmap and configuring the resource block group size.

[0166] In some cases, the order is ascending.

[0167] In some cases, the order is descending.

[0168] For example, in ascending order, the length parameter of the first resource (e.g., the number of resource blocks) is The length parameter of the second resource (e.g., the number of consecutive symbols) is .when In the HARQ-ACK information of the first and second resources in multiplexing mode, the first bit corresponds to the data in the first resource, and the second bit corresponds to the data in the second resource. More specifically, when the HARQ-ACK information is "11", it implies that the first bit "1" indicates successful reception of data in the first resource, and the second bit "1" indicates successful reception of data in the second resource.

[0169] For example, in descending order, the length parameter of the first resource (e.g., the number of resource blocks) is The length parameter of the second resource (e.g., the number of consecutive symbols) is .when In the HARQ-ACK information of the first and second resources in multiplexing mode, the first bit corresponds to the data in the second resource, and the second bit corresponds to the data in the first resource. More specifically, when the HARQ-ACK information is "11", it implies that the first bit "1" indicates successful reception of data in the second resource, and the second bit "1" indicates successful reception of data in the first resource.

[0170] In one embodiment, the sequence is based on an end position parameter derived from a RIV or bitmap corresponding to the first and second resources.

[0171] In some cases, the end position parameter of the first resource is the end resource block index of the first resource.

[0172] In some cases, the end position parameter of the second resource is the end resource block index of the second resource.

[0173] In some cases, the ending resource block index is derived from the starting resource block index and the number of resource blocks within the RIV.

[0174] In some cases, the end resource block index is derived from the last "1" in the bitmap and the configured resource block group size.

[0175] In some cases, the order is ascending. In some cases, the order is descending.

[0176] For example, in ascending order, the end position parameter of the first resource (e.g., the end resource block index) is The end position parameter of the second resource (e.g., the end resource block index) is .when In the HARQ-ACK information of the first and second resources in multiplexing mode, the first bit corresponds to the data in the first resource, and the second bit corresponds to the data in the second resource. More specifically, when the HARQ-ACK information is "11", it implies that the first bit "1" indicates successful reception of data in the first resource, and the second bit "1" indicates successful reception of data in the second resource.

[0177] For example, in descending order, the end position parameter of the first resource (e.g., the end resource block index) is The end position parameter of the second resource (e.g., the end resource block index) is .when In the HARQ-ACK information of the first and second resources in multiplexing mode, the first bit corresponds to the data in the second resource, and the second bit corresponds to the data in the first resource. More specifically, when the HARQ-ACK information is "11", it implies that the first bit "1" indicates successful reception of data in the second resource, and the second bit "1" indicates successful reception of data in the first resource.

[0178] In one implementation, the order is based on the importance of the Protocol Data Unit (PDU) set, which is determined by the General Packet Radio Service Tunneling Protocol User Plane (GTP-U) header corresponding to the first and second resources. In some cases, the order is ascending.

[0179] In some cases, the order is descending.

[0180] For example, in ascending order, the importance of the data in the first resource is... The importance of data in the second resource is .when In the HARQ-ACK information of the first and second resources in multiplexing mode, the first bit corresponds to the data in the first resource, and the second bit corresponds to the data in the second resource. More specifically, when the HARQ-ACK information is "11", it implies that the first bit "1" indicates successful reception of data in the first resource, and the second bit "1" indicates successful reception of data in the second resource.

[0181] For example, in descending order, the importance of the data in the first resource is... The importance of data in the second resource is .when In the HARQ-ACK information of the first and second resources in multiplexing mode, the first bit corresponds to the data in the second resource, and the second bit corresponds to the data in the first resource. More specifically, when the HARQ-ACK information is "11", it implies that the first bit "1" indicates successful reception of data in the second resource, and the second bit "1" indicates successful reception of data in the first resource.

[0182] In one implementation, the order is based on priority indicators corresponding to the first and second resources.

[0183] In some cases, priority indication is determined via DCI signaling.

[0184] In some cases, the order is ascending.

[0185] In some cases, the order is descending.

[0186] For example, in ascending order, the priority indicator for the data in the first resource is... The priority indicator for data in the second resource is .when In the HARQ-ACK information of the first and second resources in multiplexing mode, the first bit corresponds to the data in the first resource, and the second bit corresponds to the data in the second resource. More specifically, when the HARQ-ACK information is "11", it implies that the first bit "1" indicates successful reception of data in the first resource, and the second bit "1" indicates successful reception of data in the second resource.

[0187] For example, in descending order, the priority indicator for the data in the first resource is... The priority indicator for data in the second resource is .when In the HARQ-ACK information of the first and second resources in multiplexing mode, the first bit corresponds to the data in the second resource, and the second bit corresponds to the data in the first resource. More specifically, when the HARQ-ACK information is "11", it implies that the first bit "1" indicates successful reception of data in the second resource, and the second bit "1" indicates successful reception of data in the first resource.

[0188] In some implementations, the HARQ-ACK information in the Type-1 HARQ-ACK codebook is used for at least one of the data in the first resource and / or the data in the second resource.

[0189] In some implementations, each of the first resource and the second resource corresponds to a bit in the HARQ-ACK information within the Type-1 HARQ-ACK codebook to indicate the transmission status associated with the data in the first resource and / or the transmission status associated with the data in the second resource.

[0190] In some implementations, the Type-1 HARQ-ACK codebook includes HARQ ACK information for candidate PDSCH receive sets (also referred to herein as candidate PDSCH receive sets). For example... Figure 2 As shown, the candidate PDSCH reception set can be indicated by DCI signaling with a set of K1 values, where Nu indicates the time slot in which the UE transmits HARQ-ACK information to the BS.

[0191] In some implementations, the order of the first resource and the second resource in the candidate PDSCH reception set is based on the order in which the UE receives the data of the first resource and the data of the second resource in multiplexing mode, as described above.

[0192] In some implementations, the candidate PDSCH reception set is determined at least by a resource list or resource table, where each row includes one or more sets of parameters for each PDSCH reception (e.g., including at least one of slot offset, start and length indicator (SLIV), and / or PDSCH mapping type).

[0193] In some implementations, when receiving data of the first resource and data of the second resource in multiplexing mode, the parameter sets of the first resource and the parameter sets of the second resource are included in a row of a resource list or resource table.

[0194] For example, Figure 3 The diagram illustrates candidate PDSCH receptions for different resources within a time slot, including resources NMR0, NMR1, NMR2, NMR3, NMR4, and NMR5 in non-multiplexed mode (e.g., unicast or multicast resources not in multiplexed mode) and resources MR1 ​​(PDSCH 1) and MR2 (PDSCH 2) in multiplexed mode. In one example, the rows of resources NMR0, NMR1, NMR2, NMR3, NMR4, and NMR5 in a list or table can be represented as follows: r (row) = 0: S (starting position) = #2, L (length) = 4; r=1: S=#4, L=4; r=2: S=#8, L=3; r=3: S=#3, L=2; r=4: S=#5, L=3; and r=5: S=#11, L=4.

[0195] In one example, the rows of resources MR1 ​​and MR2 in a list or table can be represented as follows: r=6(1): S=#0, L=6; r=6(2): S=#1, L=3, Its indication corresponds to the parameter sets of resources MR1 ​​and MR2 being in the same row of the list or table (r=6).

[0196] In some implementations, when receiving data from a first resource and data from a second resource in a multiplexed mode, candidate PDSCH receptions for the first resource and the second resource are determined respectively.

[0197] For example, refer to Figure 3When receiving data from resource MR1 and data from resource MR2 in multiplexed mode, the candidate PDSCH reception includes both resource MR1 and resource MR2. Feedback (e.g., HARQ-ACK information) for resources MR1 ​​and MR2 is determined separately (e.g., using different HARQ-ACK bits). In some implementations, multiplexed mode resources (receiving data from the first and second resources in multiplexed mode) and other resources overlapping with the multiplexed resources (e.g., resources not in multiplexed mode) are not merged. Candidate PDSCH reception includes all resources in multiplexed mode.

[0198] For example, refer to Figure 3 Feedback from resources MR1 ​​and MR2 (e.g., HARQ-ACK information) can be two-bit HARQ-ACKs (one bit per resource). Feedback from resources NMR0, NMR1, NMR2, NMR3, NMR4, and NMR5 (e.g., HARQ-ACK information) can be combined into, for example, a three-bit HARQ-ACK.

[0199] In some implementations, a portion of the resources within the multiplexed mode resource is merged with other resources overlapping with the multiplexed resources in the non-multiplexed mode. Another portion of the resources within the multiplexed mode resource is determined separately. The candidate PDSCH receives the portion of the resources in multiplexed mode.

[0200] For example, the feedback from resource MR1 (e.g., HARQ-ACK information) can be combined with the feedback from resources NMR0, NMR1, NMR2, NMR3, NMR4, NMR5, and MR1 to generate, for example, a 3-bit HARQ-ACK. The feedback from resource MR2 (e.g., HARQ-ACK information) can be a 1-bit HARQ-ACK.

[0201] In one implementation, the merged resource within the multiplexing mode resource has the smallest SLIV length among the multiplexing mode resources.

[0202] In one implementation, the merged resource within the multiplexing mode resource has the largest SLIV length among the multiplexing mode resources.

[0203] In one implementation, the merged resource within the multiplexing mode resource has the smallest S0 (starting position) among the multiplexing mode resources. In one implementation, the merged resource within the multiplexing mode resource has the largest S0 (starting position) among the multiplexing mode resources.

[0204] In one embodiment, the HARQ-ACK bits for the candidate PDSCH reception of multiplexing mode resources are before the HARQ-ACK bits for the candidate PDSCH reception of other resources (merged unicast resources or multicast resources).

[0205] In one embodiment, the HARQ-ACK bits for the candidate PDSCH reception of multiplexing mode resources are after the HARQ-ACK bits for the candidate PDSCH reception of other resources (merged unicast resources or multicast resources).

[0206] In some embodiments, the HARQ-ACK information in response to one or more PDSCH receptions within a time slot includes N bits, where N is based on the maximum number of resources within a time slot.

[0207] In one embodiment, for each candidate PDSCH reception or for each time slot that needs to be fed back, the UE generates N-bit HARQ-ACK information, where N is an integer determined by the maximum number of multiplexed resources. Take Figure 2 as an example. The time slots that need to be fed back are K1 = {7, 6, 4, 3, 2, 1} (K1 = 5 is an uplink time slot, so it is excluded). Then, the UE generates 6*N-bit HARQ-ACK information to the BS, indicating that each time slot has N-bit HARQ-ACK information.

[0208] In one embodiment, for each candidate PDSCH reception or for each time slot that needs to be fed back, the UE generates corresponding N-bit HARQ-ACK information for each time slot. If there are K PDSCH receptions in a time slot, the UE generates K-bit HARQ ACK information according to the transmission status of the K PDSCH receptions respectively. As an alternative, for the N - K remaining bit HARQ-ACK information, the UE generates NACK (negative acknowledgment), where K < N, K is an integer and K >= 1.

[0209] As an alternative, for the N - K remaining bit HARQ-ACK information, the UE does not generate anything (null value).

[0210] In some embodiments, within a duration, the HARQ-ACK information in response to one or more PDSCH receptions within a time slot includes N bits.

[0211] In one embodiment, within a duration, the UE generates N-bit HARQ-ACK information for the candidate PDSCH reception or the time slot that needs to be fed back, and outside the duration, the UE generates 1-bit HARQ-ACK information for the candidate PDSCH reception or the time slot that needs to be fed back.

[0212] In some implementations, the duration is determined via RRC signaling. In some implementations, the duration is associated with the flow cycle. In some implementations, the HARQ-ACK information received in response to one or more PDSCHs within a time slot includes a 1-bit HARQ-ACK information. In one implementation, the UE generates one bit for multiplexing resources within the Type-1 HARQ-ACK codebook to indicate the transmission status of data in the multiplexing resources.

[0213] In some cases, the UE receives all resources within the multiplexed resource and generates a 1-bit HARQ-ACK by executing an AND function for all HARQ-ACK bits of all resources within the multiplexed resource.

[0214] In some cases, the UE receives a single resource within a multiplexed resource and generates a single HARQ-ACK for that single resource.

[0215] In some implementations, the first information includes a Type-2 HARQ-ACK codebook, which includes HARQ-ACK information for data in a first resource and HARQ-ACK information for data in a second resource.

[0216] In some implementations, the HARQ-ACK information for data in the first and second resources is based on the first downlink allocation index (DAI). In some cases, the first DAI differs from the counter DAI and the total DAI.

[0217] In some cases, the bit length of the first DAI field in DCI signaling is determined by the maximum number of multiplexing resources.

[0218] In some cases, the value of the first DAI in DCI signaling is associated with the number of multiplexing resources in that time slot.

[0219] For example, refer to Figure 4 The DCI signaling for scheduling each resource can have a counter DAI (Diagram showing the DCI signaling process) for statistical purposes. Figure 4 C-DAI in the middle and total DAI in the middle Figure 4In addition, for serving cell 2, at the timing corresponding to PDCCH monitoring timing index 2, the UE can receive DCI signaling for PDSCH 1 and PDSCH 2 in the scheduling multiplexing mode. For PDSCH 1 and PDSCH 2 in the multiplexing mode, the DCI signaling used to schedule PDSCH 1 and PDSCH 2 can have the first DAI (t-DAI) of the statistical multiplexing mode resources. Figure 4 The N-DAI field is 1 bit long if the maximum number of resources in the multiplexing mode is set to 2. For PDSCH 1, N-DAI = 0, and for PDSCH 2, N-DAI = 1. Therefore, for... Figure 4 In this case, the UE generates a 10-bit HARQ-ACK message.

[0220] In some implementations, when multiplexing mode resources are scheduled by a single DCI, a second DAI and / or a third DAI are used to count the resources within the multiplexing mode.

[0221] In one implementation, the second DAI is the counter DAI, and the third DAI is the total DAI.

[0222] In one implementation, the Type-2 HARQ-ACK codebook includes a first sub-codebook and a second sub-codebook.

[0223] In some cases, the UE generates HARQ-ACK bits for multiplexing mode resources in the first subcodebook.

[0224] In some cases, the UE generates HARQ-ACK bits in the second subcodebook for other resources (e.g., non-multiplexed mode resources).

[0225] In some cases, the second and third DAIs of the first subcodebook are independent of the second and third DAIs of the second subcodebook.

[0226] In some cases, the UE generates a HARQ-ACK codebook by appending the first subcodebook to the second subcodebook or by appending the second subcodebook to the first subcodebook.

[0227] For example, refer to Figure 5 The DCI signaling for scheduling each resource can have a counter DAI for resource statistics. Figure 5 C-DAI in the middle and total DAI in the middle Figure 5(T-DAI in the context of the UE). For serving cell 2, at the timing corresponding to PDCCH monitoring timing index 2, the UE can receive DCI signaling for two PDSCHs in scheduling multiplexed mode. For DCI signaling for PDSCHs in scheduling multiplexed mode, the HARQ-ACK bit can be placed in the first sub-codebook.
