Description

[0001] This document relates generally to wireless communications, and in particular to 5G communications.

[0002] Extended Reality (XR) technologies, such as AR (Augmented Reality) and VR (Virtual Reality), are emerging in a variety of use cases, such as immersive gaming, smart transportation, collaboration, and concurrent engineering. From a wireless connectivity perspective, these use cases are assumed to be supported in enhanced NR (new radio) wireless networks, which require both high data rates and low network latency.

[0003] On the BS (base station) side, the data bursts received, decoded, and rendered for the XR service may include multiple traffic cycles. Therefore, the BS can configure a CG (configured grant) cycle for the traffic cycle, where the CG resources in each CG cycle are pre-configured. However, based on the statistical value of the packet size, the CG resources may be over-configured. This is because the packet size of the data burst for the XR service may be different between each CG cycle, so a portion of the pre-configured CG resources may be wasted in a CG cycle for transmitting a data packet with a small packet size. As a result, redundant CG resources are wasted.

[0004] This document relates to methods, systems, and devices for CG communications, and in particular to methods, systems, and devices for transmitting information associated with CG transmission opportunities.

[0104] Figure 23 A flowchart of a method according to an embodiment of the present disclosure is shown.

[0105] In one embodiment, uplink control information (UCI) is applied to a duration (e.g., a CG period) in which traffic is transmitted during a portion of transmission opportunities. That is, during a duration, one or more transmission opportunities (e.g., for data transmission) may not be used, and the UCI is configured to indicate relevant information to a BS (e.g., a gNB).

[0106] In the present disclosure, unused transmission opportunities (eg, for data transmission) may be referred to as unused transmission opportunities. Similarly, used transmission opportunities (eg, for data transmission) may be referred to as used transmission opportunities.

[0107] In the present disclosure, a transmission opportunity or opportunity may be equivalent to a CG (configuration grant) PUSCH (physical uplink shared channel) opportunity or CG opportunity, and vice versa.

[0108] In one embodiment, UCI is an indication of unused transmission opportunity(s) within a duration. The duration may include one or more CG periods.

[0109] In one embodiment, UCI may be an indication of (multiple) unused transmission opportunities within a duration, where the transmission opportunities are configured by multiple CGs and / or multiple carriers and / or multiple TRPs (Transmission and Reception Points).

[0110] Figure 1 FIG. 1 shows a schematic diagram of CG transmission according to an embodiment of the present disclosure. Figure 1 , CG PUSCH opportunity #3 in both carrier 1 and carrier 2 is an unused transmission opportunity. In an embodiment of the present disclosure, UCI may indicate (multiple) used / unused transmission opportunities configured by multiple carriers in one duration to reduce signal overhead.

[0111] In one embodiment, the UCI information indicates which transmission opportunity(s) within a duration are not used. Based on this information, the gNB can reschedule these unused resources (i.e., resources preconfigured for the unused transmission opportunity(s)).

[0112] UE (user equipment) side

[0113] In one embodiment, the UCI is / includes an indication of unused CG opportunities within a duration. In this embodiment, the duration may include a single CG period or multiple CG periods.

[0114] Figure 2 A schematic diagram of CG transmission according to an embodiment of the present disclosure is shown. In this embodiment, UCI is / includes an indication of (multiple) unused CG opportunities within a duration, and the duration may be / includes N CG cycles, where N is an integer greater than 1. Specifically, the services (assumptions) at the N CG cycles are the same or similar, and the resource usage at each CG cycle is also the same or similar. In one embodiment, UCI is transmitted to the BS to indicate that the last N1 CG PUSCH transmission opportunities in each CG cycle within the duration are not used, where N1 is a positive integer. Figure 1 In the example, N1=1.

[0115] Figure 3 FIG. 1 shows a schematic diagram of CG transmission according to an embodiment of the present disclosure. Figure 3In the embodiment, the services at multiple CG periods are changing, and the UE is able to predict the amount of data. For example, in the 1st CG period, CG PUSCH opportunity #3 is not used for data transmission. And in the last CG period, CG PUSCH opportunity #2 and CG PUSCH opportunity #3 are not used for data transmission. In this embodiment, the UCI may indicate (multiple) unused CG opportunities in the duration. For example, the UCI indicates that the last (multiple) N1 CG opportunities in the 1st period of the duration are (multiple) unused transmission opportunities, the last (multiple) N2 CG opportunities in the 2nd period of the duration are (multiple) unused transmission opportunities, and so on. Therefore, for the indication of (multiple) unused CG opportunities in N CG periods, the content of the UCI may be (N1, N2, ..., NN).

[0116] In an embodiment, the UCI indicates that the opportunity(s) in a certain period in the duration and all opportunities after the certain period in the duration are not used.

[0117] In one embodiment, the UCI indicates that the opportunity(s) at the Kth cycle and all opportunities after the Kth cycle are not used. For example, the CG PUSCH opportunity is configured by CG configuration, wherein (multiple) CG PUSCH opportunities across K-1 CG cycles are configured and used for video frame transmission, while the remaining resources in the duration (e.g., a 16.67ms traffic cycle) are not used. At such an opportunity, the UE can transmit UCI indicating that the opportunity at the Kth cycle and all opportunities after the Kth cycle are not used.

[0118] In one embodiment, the CG PUSCH opportunities in the duration are configured by multiple CGs, or multiple CG groups, or in multiple carriers / cells or at multiple TRPs. In this embodiment, the UCI indicates unused resources outside of all CG PUSCH opportunities in the duration.

[0119] In one embodiment, the content in the UCI may include at least one of the following:

[0120] The number of unused CG PUSCH opportunities within N CG periods;

[0121] A time window within N CG periods; or

[0122] A bit string, where each bit indicates whether to use the CG PUSCH opportunity within N CG periods.

[0123] UCI indicates multiple CG configurations

The duration can be: the number of time slots, the period associated with the number of HARQ (hybrid automatic repeat request) process IDs, or the number of milliseconds.

[0125] In an embodiment where the UCI indicates unused transmission opportunities in one or more time durations for one or more CG configurations, the content structure of the UCI may be in the order of the CG configurations first and then in the time order.

[0126] In one embodiment, the content of the UCI is in ascending order based on the CG configuration index (eg, the configured grant configuration index (ConfiguredGrantConfigIndex)).

[0127] In one embodiment, the content of the UCI is in increasing order based on the CG group index.

[0128] In one embodiment, the content of the UCI is based on the priority order of the CG group index.

[0129] In one embodiment, the order of indication of unused CG opportunities is predefined by the BS.

[0130] For example, an unused CG opportunity with (with / having) CG opportunity index 1, CG index 2, and CG index 3 is indicated by one UCI. The content of the UCI may be {indication of CG opportunity index 2, indication of CG opportunity index 3, indication of CG opportunity index 1}.

[0131] In one embodiment, the UCI consists of or includes one or more bit blocks, wherein each bit block corresponds to a CG configuration, and each block includes information on the number of unused transmission opportunities corresponding to the CG configuration.

[0132] Figure 4 A schematic diagram of a UCI content structure according to an embodiment of the present disclosure is shown. Figure 4 In the illustrated embodiment, the UCI content structure is in the following order: bit blocks for multiple CG configurations in a first duration, bit blocks for multiple CG configurations in a second duration, and so on.

[0133] Figure 5 A schematic diagram of a UCI content structure according to an embodiment of the present disclosure is shown. Figure 5In the illustrated embodiment, the UE content structure is in the following order: bit blocks configured for the 1st CG in multiple durations, bit blocks configured for the 2nd CG in multiple durations, and so on.

[0134] Bit Matrix

[0135] In one embodiment, the bit matrix is ​​used as an indication (in the UCI) of unused transmission opportunities and / or used transmission opportunities from one or more CG configurations.

[0136] For example, the bit matrix may include indications of N transmission opportunities in M ​​CG configurations in multiple time durations, where N and M are integers.

[0137] Instead, the bit matrix follows Figure 6 In particular, the bit matrix is ​​in the following order: an indication of the transmission timing for the CG configuration in the first duration, an indication of the transmission timing for the CG configuration in the second duration, and so on.

[0138] Note that, in Figure 6 In FIG, the bit matrix is ​​depicted as a single row. Alternatively, the bit matrix may be in a form having multiple columns and multiple rows. For example, the bit matrix may be an M*N matrix.

[0139] In one embodiment, an M*N matrix may represent an indication of unused CG opportunities, wherein each row is associated with an opportunity index in the corresponding time domain and each column is associated with a CG configuration index. In the present disclosure, the M*N matrix may be named as a bit matrix form of indication-Type 0.

[0140] Figure 7 FIG. 1 is a schematic diagram showing a bit matrix indicating the transmission timing of a CG configuration according to an embodiment of the present disclosure. Figure 7 In the bit matrix, the contents are in the following order: indications for multiple CG periods in the 1st CG configuration, indications for multiple CG periods in the 2nd CG configuration, and so on.

[0141] Timing of transmitting UCI for multiple CG configurations

[0144] In one embodiment, UCI is transmitted in the transmission opportunity of (multiple) pre-configured CG configurations.

[0145] As shown in the following embodiments, the above-mentioned embodiment in which UCI indicates unused transmission opportunities for multiple CG configurations in multiple durations can also be applied to multiple cells, multiple carriers or multiple TRPs.

[0146] UCI indicates multiple cells

[0147] In some embodiments, the content of the UCI is based on the increasing order of multiple cell indexes (eg, cell identities).

[0148] In one embodiment, the UCI may be {an indication of a PCell, an indication of an SCell}.

[0149] In one embodiment, the content of the UCI is based on the priority order of the serving cells.

Figure 8 In the UCI, the UCI indicates unused transmission opportunities for one or more cells in one or more durations. Note that the UCI content is in the following order: PCell, 1st SCell, 2nd SCell in the first duration, PCell, 1st SCell, and 2nd SCell in the second duration, and so on.

[0153] Figure 9 A schematic diagram of the UCI content structure according to an embodiment of this embodiment is shown. Figure 9 In

[15] , UCI indicates unused transmission opportunities for one or more cells in one or more durations. Note that the UCI content is in the following order: multiple durations for PCell, multiple durations for 1st SCell, and so on.

[0154] Indicates the bit matrix form

[0155] In an embodiment, a bit matrix may be used to indicate used transmission opportunities and / or unused transmission opportunities from one or more cells in one or more time durations.

[0156] For example, the bit matrix includes the following information: the Nth transmission opportunity of the Mth CG configuration in the PCell and all SCells in multiple durations, where N and M are integers.

[0157] Figure 10 A schematic diagram of a UCI content structure according to an embodiment of the present disclosure is shown. Figure 10 In the first duration, the bit matrix indicates the transmission timing of the CG configuration, following the order of indications for the CG configuration, and then following the order of indications for the cell in the first duration. The same order of indications appears in subsequent durations.

[0158] Figure 11 A schematic diagram of a UCI content structure according to an embodiment of the present disclosure is shown. Figure 11 In , the bit matrix indicates the transmission timing of the CG configuration, following the order of indication for the CG configuration in a single cell, and then following the order of indication for the cell, where the transmission timing of the CG configuration for all durations in one cell is indicated first.

[0159] When to transmit UCI to indicate multiple cells

[0160] In one embodiment, UCI is transmitted in all transmission opportunities from CG configurations in both PCell and SCell in multiple time durations (e.g., multiple CG cycles).

[0161] In one embodiment, UCI is transmitted in a first transmission opportunity from a CG configuration in a PCell in a first duration.

[0162] In one embodiment, UCI is transmitted in the first transmission opportunity from the CG configuration in both the PCell and the SCell in the first duration.

[0164] In an embodiment, UCI is transmitted in a first duration in pre-configured transmission opportunity(s) from the CG configuration in both the PCell and the SCell.

[0165] UCI indicates the unused timing configured in different cell groups

[0166] In some embodiments, as Figure 12 and Figure 13 As shown, UCI indicates unused transmission opportunities from CG configurations in one or more cell groups in one or more time durations.

[0167] like Figure 12As shown, the UCI consists of a block of bits indicating that the transmission opportunities of the CG configurations follow the order indicated for the cell groups within the duration and then follow the order of the duration. Figure 13 As shown, the UCI consists of a block of bits indicating the transmission timing of the CG configuration, followed by an order of indications of the duration for the cell groups, and then followed by the order of the cell groups.

[0168] Indicates the bit matrix form

[0169] In an embodiment, a bit matrix may be used to indicate unused transmission opportunities and / or used transmission opportunities from one or more cells in one or more time durations.

In this embodiment, the bit matrix may include: the Nth transmission opportunity configured in the Mth CG in the PCell (Primary Cell), SpCell (Special Cell), and SCell (Secondary Cell) of both the MCG (Master Cell Group) and the SCG (Secondary Cell Group) in multiple durations, where N and M are integers.

[0171] Instead, the bit matrix first indicates the transmission timing of the CG configuration, following the order of indication for the CG configuration, and then following the order of indication for the cell in the first duration. And, in all subsequent durations, the same order of indication is produced (i.e., the bit matrix is ​​encoded by each duration).

[0186] UCI indicates different TRPs

[0187] In some embodiments, the UCI indicates unused transmission opportunities from a CG configuration in one or more transmission and reception points (TRPs) in one or more time durations.

[0188] Figure 16 A schematic diagram of a UCI structure according to an embodiment of the present disclosure is shown. Figure 16 In the first UCI block, the number of unused transmission opportunities for the CG configuration in the first TRP in the first duration is indicated, the number of unused transmission opportunities for the CG configuration in the first TRP in the second duration is indicated, and so on. Then, subsequent UCI blocks indicate the number of unused transmission opportunities for the CG configuration in the second TRP in the first duration, and so on (i.e., the indication is on a TRP-by-TRP basis).

[0189] Instead, the UCI indicates the total number of unused transmission opportunities for the CG configuration in the first TRP in multiple durations into the first UCI block, the total number of used transmission opportunities for the CG configuration in the second TRP in multiple durations into the first UCI block, and so on (see Figure 17 ).

[0190] Instead, an indication (e.g., a bitmap) of the CG configuration in the first TRP in the first duration is in the first UCI block, an indication of the CG configuration in the second TRP in the first duration is in the second UCI block, and so on. An indication of the CG configuration in the first TRP in the second duration is then in subsequent UCI blocks (i.e., the indication is on a per-duration basis).

[0191] Alternatively, indication information (e.g., a bitmap) of the CG configuration in the first TRP in the first duration is in the first UCI block, indication information of the CG configuration in the first TRP in the second duration is in the second UCI block, and so on, and then indication information (e.g., a bitmap) of the CG configuration in the second TRP in the first duration is in subsequent UCI blocks, and so on (i.e., the indication is TRP-by-TRP).

[0192] In one embodiment, a bit matrix is ​​used for unused transmission opportunities and / or unused transmission opportunities from one or more TRPs in one or more time durations.

[0193] In this case, the bit matrix includes: the Nth transmission opportunity of the CG configuration in the TRP in multiple durations, where N and M are integers.

[0194] Alternatively, the bit matrix first indicates the transmission timing of the CG configuration in the first TRP in the first duration, the transmission timing of the CG configuration in the second TRP in the first duration, and so on; then, it indicates the transmission timing of the CG configuration in the first TRP in the second duration, the transmission timing of the CG configuration in the second TRP in the second duration, and so on (i.e., the bit matrix is ​​encoded by duration one by one).

[0195] Alternatively, the bit matrix first indicates the transmission timing of the CG configuration in the first TRP in the first duration, the transmission timing of the CG configuration in the second TRP in the second duration, and so on; then, it indicates the transmission timing of the CG configuration in the second TRP in the first duration, the transmission timing of the CG configuration in the second TRP in the second duration, and so on (i.e., the bit matrix is ​​encoded TRP by TRP).

[0196] When to transmit UCI for multiple TRPs

[0197] In one embodiment, UCI is transmitted in all transmission opportunities of CG configurations from all TRPs in a time duration (e.g., a CG period).

[0198] In one embodiment, UCI is transmitted in all transmission opportunities of CG configurations from all TRPs in multiple time durations (e.g., multiple CG cycles).

[0199] In one embodiment, in a first (1st) duration, UCI is transmitted in a first transmission opportunity from a CG configuration in a first TRP.

[0200] In one embodiment, in a first (1st) duration, UCI is transmitted in the first transmission opportunity of the CG configuration from all TRPs.

[0201] In one embodiment, in a first (1st) duration, UCI is transmitted in a pre-configured (one or more) transmission opportunity(s) from the CG configuration in the first TRP.

[0202] In one embodiment, UCI is transmitted in a first (1st) duration in a preconfigured transmission opportunity(s) from a CG configuration in a preconfigured TRP.

[0203] UCI for one of multiple CG configurations

[0204] In some embodiments, the UCI indicates a selected CG configuration from among the preconfigured CG configurations. For example, the UCI may indicate the index of the selected CG configuration. The resources of the CG configuration are allowed to overlap with the resources of another CG configuration in the time domain or frequency domain.

[0205] In some embodiments, the UCI includes an indication of "UCI is used for 1 cycle" or "UCI is used for N cycles".

[0206] In one embodiment, the indication is a 1-bit flag in the UCI, indicating that the UCI is used for 1 cycle or the UCI is used for N>1 cycles.

[0207] For example, UCI is 5 bits, 1 bit of which indicates whether the UCI indicates a timing in 1 cycle, and the other 4 bits indicate resources not used in 1 cycle.

[0208] In an embodiment, the UCI is 9 bits, and 1 bit indicates whether the UCI indicates an opportunity in 1 cycle, and the other 8 bits indicate resources that are not used for a duration that may be two cycles.

[0209] In one embodiment, for UCIs for the same duration, the content of the UCIs should be the same.

[0210] In one embodiment, for UCIs indicating the same duration, if the content of a UCI is different from the previous UCI, the 1-bit flag of the UCI may indicate that it applies for 1 cycle. In this embodiment, overriding the UCI only changes the unused timing in a corresponding cycle.

[0211] UE reports UE capabilities

[0212] In an embodiment, the UE reports its UE capability of reporting non-use indication of CG PUSCH opportunities in multiple periods.

[0213] In one embodiment, the UE reports whether it has the UE capability to report non-usage indications of CGPUSCH opportunities for multiple CG configurations, multiple carriers / cells, and multiple TRPs.

[0214] In an embodiment, the UE reports its UE capability of whether to report an indication of non-use of CG PUSCH opportunities of the shared spectrum.

[0215] CG PUSCH timing configuration

[0216] In one embodiment, the UCI mechanism is based on CG PUSCH opportunities configured within a duration (eg, within a CG period). In the following, a method is shown on how to configure multiple CG PUSCH opportunities within a CG period.

[0217] In one embodiment, the network (e.g., BS) configures the CG PUSCH timing within the CG period by configuring RRC (Radio Resource Control) parameters. For example, the network configures a table labeled PUSCH-TimeDomainResourceAllocation size (1...maxN), which has maxN rows, where each row indicates the time domain resource allocation of multiple configured granted PUSCHs in the CG period. For example, each row is labeled PUSCH-Allocation SIZE (1...maxNrofMultiCG PUSCH), where maxNrofMultiCG-PUSCH is the maximum number of CG PUSCHs in the CG period, for example, maxNrofMultiCG-PUSCH=8.

[0218] In addition, each PUSCH-Allocation indicates a startSymbolAndLength (starting symbol and length) and an offset (offset).

[0219] In one embodiment, startSymbolAndLength indicates the starting symbol position and the length of the PUSCH.

[0220] In one embodiment, offset refers to / refers to the time offset between the PUSCH and the reference point.

[0221] For example, startSymbolAndLength can be set to S, and the length represented as L:

[0222] if(L-1)<=7then

[0223] startSymbolAndLength=14*(L-1)+S

[0224] else

[0225] startSymbolAndLength=14*(15-L)+(13-S)

[0226] the value of startSymbolAndLength can be (0...127).

[0227] In one embodiment, the DCI (Downlink Control Information) format indicates a row index of a table, which is configured via RRC (signaling). The configured table may be the table in the above embodiment, where each row indicates the time domain resource allocation of multiple configured grants PUSCH in the CG period.

[0228] In one embodiment, the offset may be a time offset between the PUSCH and a reference point, and the reference point is a time slot when the DCI is received.

[0229] In one embodiment, the bit field of the time domain resource allocation in the DCI format (e.g., DCI format 0-0, format 0-1, DCI format 0-2) indicates an index, where the index is linked to information of a row in a TDRA (Time domain resource assignment) table (e.g., the TDRA table can be the TDRA table shown in the above embodiment).

[0230] In one embodiment, the RRC parameters include: ConfiguredGrantConfigForMultiPUSCHs (configured grant configuration for multiple PUSCHs), which includes rrc-ConfiguredUplinkGrantMultiPUSCHs (rrc-configured uplink grant for multiple PUSCHs).

[0231] In one embodiment, rrc-ConfiguredUplinkGrantMultiPUSCHs includes time domain parameters, which provide multiple timeDomainOffsets and multiple PUSCH-Allocations.

[0232] In one embodiment, timeDomainOffset refers to / refers to the time offset between the PUSCH and the reference point (for example, the time offset of each CG PUSCH associated with the reference SFN (reference subframe number, reference subframe number), such as Figure 18 shown).

[0233] Specifically, each PUSCH allocation indicates startSymbolAndLength.

[0234] startSymbolAndLength indicates the starting symbol position and the length of the PUSCH.

[0235] The network may configure a table containing multiple PUSCH allocations, which may be the same as in the above embodiment.

[0236] In one embodiment, the RRC parameters include ConfiguredGrantConfigForMultiPUSCHs.

[0237] In one embodiment, ConfiguredGrantConfigForMultiPUSCHs includes rrc-ConfiguredUplinkGrantMultiPUSCHs, where rrc-ConfiguredUplinkGrantMultiPUSCHs includes time domain parameters, which provide timeDomainOffset and sub-offset.

[0238] In one embodiment, the sub-offset represents the time offset between adjacent CG PUSCH opportunities.

[0239] In one embodiment, the network configures a new (TDRA) table for time domain resource allocation for multiple PUSCHs within a CG period. The new table contains PUSCH allocations and PUSCH allocations. Note that this table may not indicate an offset. The network configures up to 16 rows in the TDRA table, where each row contains multiple time domain allocations.

[0240] In one embodiment, the formula in 3GPP TS 38.321 is reused and each timeDomainOffset is applied to the formula for generating the corresponding CG PUSCH opportunity in the next cycle and subsequent cycles.

[0241] In one embodiment, the network may configure a new (TDRA) table for time domain resource allocation of multiple PUSCHs in a CG period. The network may configure a maximum of 32 rows in the TDRA table. In this embodiment, the network may indicate whether to use the new TDRA table.

[0242] For example, higher layer signaling indicates whether to use a new TDRA table, where the TDRA table contains 32 rows, and each row indicates time domain resource allocation for multiple CG PUSCH opportunities.

[0243] In one embodiment, the RRC parameters include: ConfiguredGrantConfigForMultiPUSCHs, which includes rrc-ConfiguredUplinkGrantMultiPUSCHs. The rrc-ConfiguredUplinkGrantMultiPUSCHs includes time domain parameters for providing multiple time domain offsets and PUSCH allocations. The PUSCH allocation indicates the starting symbol and length (startSymbolAndLength).

[0244] Determine the resource allocation table for CG PUSCH

[0245] In the following, an embodiment of a table for PUSCH time domain resource allocation configuration is shown.
