[0044] In beyond 5G and 6G communications, a promising service has the characteristics of quasi-periodicity (affected by jitter), large and diverse data volumes, and strict latency requirements, including, for example, extended reality (XR) services. In the prior art, authorized transmissions, including configured grants (CG) and semi-persistent scheduling (SPS), are able to transmit periodic data through pre-configured resources without the need for authorization requests and excessive power consumption. However, due to the quasi-periodicity and the service characteristics of large and diverse data volumes, current SPS and CG do not support the transmission of such services. To this end, multiple SPS configurations and multiple CG configurations with adaptive parameter adjustment should be considered to support SPS / CG configurations for the transmission of XR services, wherein the adaptive parameter adjustment (such as activation, deactivation, parameter update, and resource fast authorization and release) is determined by control signaling. The present disclosure aims to propose a method for how the control signaling of adaptive parameter adjustment works.

[0045] The example titles of the following sections are used to facilitate understanding of the disclosed subject matter and do not limit the scope of the claimed subject matter in any way. Therefore, one or more features of one example section can be combined with one or more features of another example section. In addition, for the sake of clarity of explanation, 5G terminology is used, but the technology disclosed in this document is not limited to 5G technology, but can also be used in wireless systems implementing other protocols.

[0046] I. Introduction

[0047] Figure 1A-1BThe timeline of the current semi-persistent scheduling (SPS) and currently configured grant (CG) transmission is shown. For SPS transmission or CG transmission, the gNB first transmits RRC signaling SPS-config or ConfiguredGrantConfig, respectively. Then, DCI is used to activate SPS transmission or CG transmission. Finally, SPS transmission or CG transmission is activated, and data will be transmitted periodically in preconfigured resources. For SPS or CG transmission, the first SPS physical downlink shared channel (PDSCH) is received or the CG physical uplink shared channel (PUSCH) is transmitted in K time slots after the UE receives the DCI with the SPS or CG activation indication. At the same time, the gNB needs to receive HARQ-ACK information to confirm whether the UE has received the deactivation indication. Considering the processing capability of the UE, the HARQ-ACK information for the deactivation indication is transmitted in N symbols after the deactivation indication is received.

[0048] Figure 2 Shows the configuration of the current SPS or the current CG. Figure 3 Multiple SPS PDSCH configurations and multiple CG PUSCH configurations with adaptive parameter adjustment are shown. Figure 2-Figure 3 The one or more control signals may include configuration-related parameters, where the parameters may be related to activation, deactivation, parameter update, etc., and may have their own timelines. The control signaling may include radio resource control (RRC) signaling, downlink control information (DCI) signaling, and / or UCI signaling. The timeline of one or more control signaling may include the following: (1) Figure 4 As shown, from control signaling to resources; (2) as Figure 5 As shown, from control signaling to another control signaling; (3) as Figure 6 As shown, from resources to control signaling.

[0049] exist Figure 4 In the case (1) shown, when control signaling is transmitted or received in the nth time slot / symbol, the control signaling is valid for the SPS resource in the (n+K)th time slot / symbol, or the UE performs transmission or reception in the SPS resource in the (n+K)th time slot / symbol, or the UE performs an action in the (n+K)th time slot / symbol, such as activation, deactivation, or parameter update of the SPS resource. In the patent document, n and K are integers greater than or equal to 1.

[0050] exist Figure 5 In the case (2) shown, when the first control signaling is transmitted in the nth time slot / symbol, the control signaling is valid for the SPS resource when the second control signaling (e.g., DCI or an acknowledgment indication such as HARQ-ACK) is received or transmitted in the (n+K)th time slot / symbol, and then the UE performs transmission or reception in the SPS resource after the (n+K)th time slot / symbol, or the UE performs an action after the (n+K)th time slot / symbol, such as activation, deactivation, or updating of the SPS resource.

[0051] Alternatively, in Figure 5 In the case (2) shown, when the second control signaling (e.g., DCI or an acknowledgment indication such as HARQ-ACK) is transmitted or received in the nth time slot / symbol, the first control signaling should be transmitted or received in the (nK)th time slot / symbol or before the (nK)th time slot / symbol.

[0052] In the patent document, operations associated with one or more time slots / symbols may refer to operations of transmission or reception of an uplink channel (e.g., PUSCH) or a downlink channel (e.g., PDSCH), respectively, or do not include operations performed by the UE such as activation / deactivation of SPS resources. Figure 6 In the case (3) shown, when the transmission configuration of the SPS is associated with the nth, ... (n+delta)th, ... (n+K-1)th time slots / symbols, respectively, the control signaling is valid for the SPS resource in the (n+K)th time slot / symbol, or the UE performs transmission or reception in the SPS resource in the (n+K)th time slot / symbol, or the UE performs an action in the (n+K)th time slot / symbol, such as activation, deactivation, and confirmation of multiple SPS resources. In the example of case (3), the control signaling transmitted in the (n+K)th time slot / symbol can be an acknowledgment indication such as HARQ-ACK, which can be associated with data received in the SPS resources in the nth, ... (n+delta)th, ... (n+K-1)th time slots / symbols, or can be used to indicate the data.

[0053] In addition, Figure 4 In the case shown, when the operation is associated with the nth time slot / symbol, the control signaling should be transmitted or received in the (nK)th time slot. For example, when the UE performs transmission / reception / operation in the SPS resource in the nth time slot / symbol, uplink control information (UCI) for activating / deactivating the SPS resource can be transmitted or received in the (nK)th time slot.

[0054] In the patent document, the term SPS may refer to an SPS configuration for a downlink or a CG configuration for an uplink. In the patent document, the term SPS resource may refer to an SPS PDSCH for a downlink or a CG PUSCH for an uplink, and the term time and frequency resources are similar to the term SPS resources. In the patent document, the term operation may refer to transmission, reception, etc.

[0060] In some embodiments, the SPS configuration includes an SPS configuration index, wherein the SPS configuration includes an index corresponding to any one or more of the following:

[0061] 1. An information set for SPS configuration indexing, comprising any one or more of the following:

[0062] a. Periodicity information, which indicates the time length between a time and frequency domain resource and its previous and / or next time and frequency domain resource, or the time length between a time and frequency domain resource group and its previous and / or next time and frequency domain resource group, wherein the time and frequency resource group includes one or more time and frequency resources.

[0063] b. Duration length information, wherein the length information indicates the time length associated with the time and frequency resource group allocated to the UE, wherein the time length may be less than or equal to Figure 2 and Figure 3 Periodic information shown.

[0064] c. A valid or invalid indication that identifies one or more time slots that can be used for one or more time and frequency resources within a duration. In one example, a bitmap may be used to indicate the valid or invalid indication of a time slot.

[0065] d. Offset information, which indicates the time offset between two adjacent time and frequency resources within a time and frequency resource group.

[0066] 2. Some SPS resources

[0068] exist Fig.12 , the first time and frequency resources are transmitted or received in the Mth time slot, the second time and frequency resources are transmitted or received in the (M+10)th time slot, and so on.

[0069] In another example, the SPS configuration includes an SPS configuration index, which corresponds to the periodicity information, that is, the periodicity in SPS-config or the periodicity in ConfiguredGrantConfig, such as "10ms" or "10ms x 14 symbols", the length information of the duration is "5 time slots", the valid or invalid indication is a bitmap "10101", and the SPS configuration is as follows Fig.13 shown.

[0070] exist Fig.13 In the example, the first time and frequency resource group represented as resource group 1 includes the first time and frequency resources to the third time and frequency resources. If the offset information is set to "1 time slot", this pattern can also be realized, which is similar to the valid or invalid indication being set to "10101".

[0075] a. Periodic information for different SPS configuration indexes in the SPS set

[0076] b. Offset information for different SPS configuration indexes in the SPS set

[0077] c. Information about the number of SPS configuration indexes.

[0078] In one example, if you configure Fig.13The SPS set in the SPS configuration includes three SPS configuration indexes, such as {4, 5, 6}. As a result, the quantity information or number of SPS configuration indexes (such as Fig.13 The periodicity information of the three SPS configuration indexes is set to "10ms", and the offset information of the SPS configuration indexes from 4 to 6 is set to "0", "2" and "4", respectively.

[0079] exist Fig.14 In Fig.13 The patterns are similar, but the SPS set configurations are different. There are multiple SPS sets, and the gNB indicates one of the SPS sets for configuring the corresponding pattern based on the number information of the SPS configuration index.

[0080] According to the above example, the time and frequency resource groups are associated with the number information of the SPS configuration indexes, the multiple SPS configuration indexes, and the offset information.

[0109] C. In some cases, DCI signaling is used for SPS parameter updates

[0110] · The parameters of the DCI signaling include a DCI field to indicate that the DCI signaling is for SPS parameter update. · In some cases, the DCI field for update indication includes at least one of the following: "HARQ process number", "redundancy version"; "downlink allocation index"; "TPC command for scheduled PUCCH"; or "VRB to PRB mapping". One or more of these fields are reinterpreted as an update indication with P bits, where P is a positive integer. For example, when "redundancy version"

[0111] When set to all 1s and configured with duration length information, valid or invalid indication, or offset information, the LSB of the "HARQ process number" is an update indication. The update indication is set to "1", which means that the DCI is used for SPS parameter update, and the update indication is set to "0", which means that the DCI is not used for SPS parameter update. The state of the DCI field for SPS parameter update is different from the state of the DCI field for SPS activation.

[0112] In this case, the SPS parameters include any one or more of the following:

[0113] 1. Modulation and coding scheme (MCS) level

[0114] 2. Information of MCS table

[0115] 3. Time domain resource assignment (TDRA)

[0116] 4. Frequency domain resource assignment (FDRA)

[0117] 5. Number of layers

[0118] 6. Periodic Information

[0119] 7. Valid or invalid instructions

[0120] 8. Offset information

[0121] • The update parameters are valid in one or more time and frequency resource groups.

[0122] For example, Fig.15 As shown, the update DCI signaling updates the above parameters of the time and frequency resources in a time-frequency resource group.

[0123] For group common DCI, such as DCI format 2_6 or the newly defined DCI format 2, the parameters of the SPS configuration in the DCI signaling determine different types of indications through specially defined fields.

[0124] A. In some cases, DCI signaling is used for SPS activation or SPS deactivation / release

[0125] The parameters of the DCI signaling include a newly defined DCI field to indicate that the DCI signaling is for SPS activation. The newly defined field for indicating that the time and frequency resources in the time and frequency resource group are activated or deactivated is an "activation / release indication" with a length of one bit. When the field is indicated by "1", it means that the time and frequency resources in the time and frequency resource group are activated, and when the field is indicated by "0", it means that the time and frequency resources in the time and frequency resource group are activated.

[0126] When indicated, it means that the time and frequency resources in the time and frequency source group are released / deactivated.

[0127] B. In some cases, DCI signaling is used for SPS parameter updates

[0128] The parameters of the DCI signaling include a newly defined DCI field to indicate that the DCI signaling is for SPS parameter update. The newly defined field for indicating that the DCI signaling is for SPS parameter update. Other defined fields indicate update parameters such as MCS level; information of the MCS table; time domain resource allocation (TDRA); frequency domain resource allocation (FDRA); number of layers; periodicity information; valid or invalid indication; offset information.

[0129] o In some embodiments, the control signaling is uplink control information (UCI) signaling, including at least one (or any one or more) of an acknowledgement indication, an activation indication, or a deactivation indication.

[0130] The following example is based on Fig.16 .

[0131] In the example of confirmation indication, the UCI signaling is HARQ-ACK information of one or more time and frequency resources in the time and frequency resource group. Fig.16 , the first HARQ-ACK information is associated with the first two CG PUSCHs in resource group 1, and the second HARQ-ACK information is associated with all CG PUSCHs in resource group 2, where the time and frequency resource groups are represented by resource groups and the time and frequency resources are represented by CG PUSCHs.

[0132] The following example is based on Fig.17 .exist Fig.17 In the example, for activation or deactivation / release indication, the first activation UCI activates the first two CG PUSCHs in resource group 1, and when the UE receives the first release UCI, the third CG PUSCH is released. When the second activation UCI activates the second CG PUSCH, and when the UE does not receive the second activation UCI and the UE receives the second release UCI, the first CG PUSCH and the third CG PUSCH are released in resource group 2, respectively, where the time and frequency resource groups are represented by resource groups, and the time and frequency resources are represented by CG PUSCHs.

[0133] For example, the UCI signaling is a scheduling request (SR) for indicating activation, which means that one or more time and frequency resources in the time and frequency resource group are used for data transmission.

[0134] For example, the UCI signaling is a scheduling request (SR) for indicating deactivation / release, which means that one or more time and frequency resources in the time and frequency resource group are not used for data transmission.

[0135] For example, UCI signaling is a newly defined signaling, instead of HARQ-ACK information, scheduling request, CSI report, and carries activation indication and deactivation / release indication information. In some cases, there is one-bit length information in the newly defined signaling, where bit "1" indicates activation, meaning that one or more time and frequency resources in the time and frequency resource group are used for data transmission, and bit "0" indicates deactivation, meaning that another one or more time and frequency resources in the time and frequency group are not used for data transmission.

[0170] b. In some cases, K2min is the minimumSchedulingOffsetK2 in the RRC signaling PUSCH-Config.
