In an embodiment, if a high layer parameter nrof_UTO_UCI is configured for a single CG (configured grant) configuration, the UTO-UCI is transmitted in CG PUSCH transmission (s) of the single CG configuration. The bits of the UTO-UCI for the single CG configuration have a one-to-one mapping to subsequent CG-PUSCH transmission occasions in an ascending order of their start times, where the CG-PUSCH transmission occasions are valid CG-PUSCH transmission occasions and invalid configured PUSCH grant (s) that are not transmitted due to collision with DL symbol (s) indicated by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated, if provided. If multiple CG configurations are configured for/to the UE and they all support the transmissions of the UTO-UCI, the UTO-UCI may be transmitted in CG periods of each CG configuration, resulting in significant signaling overhead. To this end, the UTO-UCI (signaling) for multiple CG configurations is proposed. To this end, the following topics may need to be discussed.

In the present disclosure, the CG-PUSCH transmission occasions may refer to transmission occasions, PUSCHs or CG-PUSCHs, and vice versa. That is, the transmission occasions have the same meaning as CG PUSCH transmission occasions in some embodiments. In some embodiments, the CG PUSCHs have the same meaning as CG PUSCH transmission occasions. In some embodiments, the PUSCHs have the same meaning as CG PUSCH transmission occasions. In some embodiments, the CG-PUSCH transmission occasions have the same meaning as CG PUSCH transmission occasions (i.e. without “-” ) .

FIRST SIGNALING INDICATION

In some embodiments, a first signaling is proposed. The first signaling may include the UTO-UCI for multiple CG configurations. The first signaling may be a bitmap type. The first signaling may be transmitted in (valid) CG PUSCH transmission occasions of the multiple CG configurations. The first signaling may be configured to have O^UTO-UCI length and/or an effective period/duration, wherein O^UTO-UCI is a positive integer. The effective period/duration is (determined based on) the O^UTO-UCIlength of the first signaling.

In an embodiment, the effective period/duration includes O^UTO-UCI valid CG PUSCH transmission occasions.

In some embodiments, the first signaling comprises a bitmap, which comprises bits one-to-one mapped to the transmission occasions of the plurality of CG configurations in the CG group in the effective period in an ascending order of a start time of each transmission occasion.

In an embodiment, the bitmap has a one-to-one mapping to O^UTO-UCI subsequent CG-PUSCH transmission occasions for the corresponding CG configurations in the effective period in ascending order of start time.

In some cases, the value of O^UTO-UCI is determined by the parameter nrof_UTO_UCI in ConfiguredGrantConfig

In some cases, the value of O^UTO-UCI is determined by the parameter nrof_UTO_UCI-r19 in ConfiguredGrantConfig. In these cases, the parameter nrof_UTO_UCI is ignored when the parameter nrof_UTO_UCI-r19 is configured.

In the present disclosure, the CG PUSCHs or transmission occasions in/of the CG configuration (s) may refer to the CG PUSCHs or transmission occasions in CG period (s) of the CG configuration (s) .

In an embodiment, the first signaling indicates usage of Nu valid CG PUSCHs in an effect period, where Nu is a positive integer and the Nu valid CG PUSCHs belong to multiple CG configurations.

FIG. 1 shows a schematic diagram of a first signaling according to an embodiment of the present disclosure. In FIG. 1, the first signaling (e.g., the UTO-UCI) comprises a 4-bit bitmap “XXXX” (i.e., Nu=4) , wherein each bit is used/configured to indicate the usage of 4 CG PUSCHs of the CG configurations 2 to 3. Specifically, the 1st bit of the bit map indicates the usage of the 1st CG PUSCH belonging to the CG configuration 2 in the effective period of the first signaling, the 2nd bit of the bit map indicates the usage of the 2nd CG PUSCH belonging to the CG configuration 3 in the effective period of the first signaling, the 3rd bit of the bit map indicates the usage of the 3rd CG PUSCH belonging to the CG configuration 2 in the effective period of the first signaling, and the 4th bit of the bit map indicates the usage of the 4th CG PUSCH belonging to the CG configuration 3 in the effective period of the first signaling. That is the first signaling is configured to indicates the usage of the CG PUSCHs of all related CG configurations in the effective period of the first signaling according to/in time sequence/order of the CG PUSCHs of all related CG configurations. The value of X can be ‘1’ or ‘0’ .

In some embodiments, the multiple CG configurations belong to one cell. That is, in these cases, the UE does not expect that the first signaling indicates whether the CG PUSCH transmission occasions are unused or not in multiple CG configurations cross different cells.

In an embodiment, the UE does not except to use/configure the UTO-UCI to indicate the CG PUSCH transmission occasions are unused for more than one CG configuration cross different cells.

In some cases, the bits of the first signaling have one-to-one mapping to O^UTO-UCI subsequent CG PUSCH transmission occasions in multiple CG configurations in an ascending order of their start times.

In some cases, a bit value of ‘0’ in the first signaling indicates that the UE may transmit CG-PUSCH, and a bit value of ‘1’ in the first signaling indicates that the UE will not transmit CG-PUSCH, in a corresponding CG-PUSCH TO (transmission occasion) .

In some cases, the O^UTO-UCI subsequent CG-PUSCH TOs do not include invalid CG PUSCH TOs where a UE does not transmit a PUSCH of the CG configuration in the cell due to collision with the DL symbol (s) indicated by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated if provided, or a symbol (s) of an SS/PBCH block with index provided by ssb-PositionsInBurst.

In some cases, the multiple CG configurations are all CG configurations configured to the UE.

In some cases, the multiple CG configurations belongs to a CG group configured to the UE.

As shown in FIG. 2, there are two CG configurations in the CG group (i.e., CG configuration 1, CG configuration 2) in the same cell. For the first signaling transmitted in the CG PUSCH transmission occasion#0 of the CG configuration 1, the effective time starts after the CG PUSCH transmission occasion#0 of CG configuration 1. In this embodiment, O^UTO-UCI is set to 4. In other words, the first signaling transmitted in the CG PUSCH transmission occasion#0 of CG configuration 1 indicates O^UTO-UCI = 4 transmission occasions after the CG PUSCH transmission occasion#0 of CG configuration 1. In the first signaling, there are 4 bits one-to-one mapping to the 4 transmission occasions of the CG configuration 1 and the CG configuration 2 in an ascending order of the start time. Specifcially, CG PUSCH transmission occasion#0 of the CG configuration 2, CG PUSCH transmission occasion#1 of the CG configuration 1, CG PUSCH transmission occasion#1 of the CG configuration 2 and CG PUSCH transmission occasion#2 of the CG configuration 2 are indicated by the first signaling in in the CG PUSCH transmission occasion#0 of CG configuration 1. Their start times are 15th symbol (first symbol of Slot#1) , 29th symbol (first symbol of Slot#2) , 43th symbol (first symbol of Slot#3) and 57th symbol (first symbol of Slot#4) , respectively. According to the start times of these four transmission occasions indicated by the first signaling, the bitmap in the first signaling sequentially indicate the CG PUSCH transmission occasion#0 of the CG configuration 2, the CG PUSCH transmission occasion#1 of the CG configuration 1, the CG PUSCH transmission occasion#1 of the CG configuration 2 and the CG PUSCH transmission occasion#2 of the CG configuration 2 from the most significant bit to the least significant bit of the bitmap.

In some embodiments, the multiple CG configurations belong to different cells.

In some cases, the bits of the first signaling have one-to-one mapping to Nu subsequent in CG PUSCHs in multiple configurations cross difference cells in an ascending order of the start times of the CG PUSCHs.

In some embodiments, the effective period is (determined based on) the length of bitmap.

In some embodiments, the effective period is based on the reference point.

In some embodiments, the start time of each transmission occasion is based on the reference point.

In an embodiment, the reference point is subcarrier spacing.

In an embodiment, the reference point is a symbol index.

In an embodiment, the reference point is a slot index.

In some cases, the start times of the transmission occasions in different cells are transport/transferred to the distance/difference between the start time of each transmission occasion in the corresponding cell and the reference point.

In these cases, the distance/difference is expressed as

wherein S_cell denotes the start time (symbol index) of the transmission occasion in its belonging cell, S_ref denotes the symbol index of the reference point, μ_celldenotes the subcarrier spacing of the cell of the transmission occasion and μ_ref denotes the subcarrier spacing of the reference point. The subcarrier spacing follows the relationship as:

In an embodiment, the length of the effective period is determined by the reference point.

In some cases, the effective period starts from the slot after the slot of CG PUSCH transmission occasion of the first signaling transmission.

In some cases, the start time of each transmission occasion is based on the subcarrier spacing of the primary cell.

As shown in FIG. 3, there are two CG configurations in the CG group (i.e., CG configuration 1 and CG configuration 2) in two different cells, cell 1 and cell 2. For the first signaling transmitted in the CG PUSCH transmission occasion#0 of the CG configuration 1, the effective time starts after the starting symbol of the CG PUSCH transmission occasion#0 of the CG configuration 1. The first signaling indicates O^UTO-UCI = 4 transmission occasions after the CG PUSCH transmission occasion#0 of the CG configuration 1. In this embodiment, it is assumed that the reference point is the first symbol of the cell 1 and the subcarrier spacings of the cell 1 and cell 2 are 15kHz (μ=0) and 30kHz (μ=1) , respectively. The distance between the CG PUSCH transmission occasion#0 of CG configuration 2 and reference point is D1 = (14-0) * (1/2) = 7. Similarly, the distance between the CG PUSCH transmission occasion#1 of the CG configuration 2 and the reference point is D2 = (42-0) * (1/2) = 21, the distance between the CG PUSCH transmission occasion#1 of the CG configuration 1 and the reference point is D3 = (28-0) * (1/1) =28, the distance between the CG PUSCH transmission occasion#2 of the CG configuration 2 and the reference point is D4 = (70-0) * (1/2) = 35. According to the distances of start times of these four transmission occasions and the reference point indicated by the first signaling, the bitmap in the first signaling indicates (the usage) the CG PUSCH transmission occasion#0 of the CG configuration 2, the CG PUSCH transmission occasion#1 of the CG configuration 2, the CG PUSCH transmission occasion#1 of the CG configuration 1 and the CG PUSCH transmission occasion#2 of the CG configuration 2 from the most significant bit to the least significant bit.

In some cases, the start time of the effective period of the first signaling is based on the time domain location of the first (1st) CG PUSCH in the effective period in the serving cell with the smallest index in the cell group.

In some cases, the start time of the effective period of the first signaling is based on the time domain location of the first (1st) CG PUSCH in the effective period in the serving cell with the largest index in the cell group.

In some cases, the start time of the effective period of the first signaling is based on the time domain location of the first (1st) CG PUSCH in the effective period in the serving cell with a predefined index in the cell group, where the preconfigured index is determined by an RRC (radio resource control) signaling.

In some cases, the start time of the effective period of the first signaling is based on the time domain location of the first (1st) CG PUSCH in the effective period in the primary serving cell.

In some cases, the subsequent CG PUSCHs of the multiple CG configurations is located at the earliest UL symbol after the last symbol of preceding CG PUSCH in the effective period.

In some cases, the multiple CG configurations are all CG configurations configured by a UE.

In some cases, the multiple CG configurations belongs to a CG configuration group configured by a UE.

In some cases, the first signaling comprises the UTO-UCI.

MULTIPLE CG CONFIGURATIONS CORRELATION

In an embodiment, the high layer signaling is an RRC signaling. For example, the name of the RRC signaling is UTO_UCI_ForMultiCG, or nrof_UTO_UCI-r19.

In some cases, the RRC signaling indicates the CG group identifier for determining the CG group.

In some cases, if the UE is provided a high layer parameter with the value equal to a time duration in the high layer signaling of the plurality of CG-PUSCH configurations, the UE multiplexes the UTO-UCI represented by multiple bitmaps in the time duration of O^UTO-UCI bits in each CG-PUSCH transmission for the corresponding CG-PUSCH configurations.

In an embodiment, the high layer signaling is in ConfiguredGrantConfig.

In an embodiment, the high layer signaling is in PUSCH-Config.

In an embodiment, the high layer signaling is the RRC signaling configuring the CG group information, where CG group comprises the plurality of CG configurations. For example, the name of RRC signaling is CGgroup, CGgroupID, CorrelatedCGID.

In an embodiment, the UE is provided a high layer parameter with the value equal to a time duration in the high layer signaling of the plurality of CG-PUSCH configurations.

For example, the name of the RRC signaling may be CGgroupID and the value of CGgroup ID can be 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, or 16. Moreover, the RRC signaling is in ConfiguredGrantConfig. Assuming there are 3 CG configurations CG0, CG1, and CG2 in the CG group with index 0, the RRC signaling CGgroupID is set to 0 in the ConfiguredGrantConfig of the CG0, the RRC signaling CGgroupID is set to 0 in the ConfiguredGrantConfig of the CG1, and the RRC signaling CGgroupID is set to 0 in the ConfiguredGrantConfig of the CG2. In such configurations, it implies that the CG group 0 comprises the CG0, the CG1, and the CG2. When/if the CGgroupID is configured, the UTO_UCI can indicate the CG PUSCHs of the CG0, the CG1 and the CG2 in the CG group 0.

In some cases, the first signaling indicates the usage of the CG PUSCHs of multiple CG configurations belonging to a single cell, multiple cells, or multi-TRPs (transmission reception points) .

In some cases, the first signaling includes UTO-UCI indicating whether the valid CG PUSCH transmission occasions belonging to multiple CG configurations in the effective period are unused or not, which is determined by an RRC (radio resource control) signaling.

For example, if the RRC signaling is configured, the first signaling indicates whether the valid CG PUSCHs belonging to multiple CG configurations in the effective period are unused or not. If the RRC signaling is not configured, the first signaling indicates whether the valid CG PUSCHs belonging to single CG configuration in the effective period are unused or not.

As an alternative, if a CG group is configured (by the RRC signaling) , the first signaling indicates the usage of valid CG PUSCHs belonging to multiple CG configurations, while if the CG group is not configured (by the RRC signaling) , the first signaling indicates the usage of valid CG PUSCHs belonging to single CG configuration.

In some cases, the multiple CG configurations belong to a CG group determined by the gNB.

In some cases, the CG configurations may be grouped according to their CG configuration indexes/IDs. For example, the CG configurations with IDs {0, 1, 2, 3} are in a group 1, the CG configurations with IDs {4, 5, 6, 7} are in a group 2, and so on. The number of CG configurations in one group and/or the number of groups is determined by an RRC signaling.

In some cases, the RRC signaling indicates the CG configuration index list for determining the CG group. For example, the name of RRC is CGIDlist, CGindexList where the RRC signaling is a sequence of integer. Moreover, the RRC signaling is in ConfiguredGrantConfig.

In some cases, the CG configuration index list includes all the CG configuration indexes in the same group.

In an embodiment of 3 CG configurations CG0, CG1, and CG2 in the CG group, the RRC signaling (e.g., CGIDlist or CGindexList) is set to {0, 1, 2} in all the ConfiguredGrantConfig of the CG0, the CG1 and the CG2. In such configurations, it implies that the CG group comprises the CG0, the CG1, and the CG2. When/If the CGIDlist is configured, the UTO_UCI can indicate the CG PUSCHs of the CG0, the CG1, and the CG2 in the CG group.

As an alternative, the CG configuration index list includes the CG configuration indexes except the CG configuration index of the CG configuration for which the high layer signaling is transmitted.

In an embodiment of 3 CG configurations CG0, CG1, and CG2 in the CG group, the RRC signaling (e.g., CGIDlist or CGindexList) is set to {1, 2} in the ConfiguredGrantConfig of the CG0, the RRC signaling (e.g., CGIDlist or CGindexList) is set to {0, 2} in the ConfiguredGrantConfig of the CG1 and the RRC signaling (e.g., CGIDlist or CGindexList) is set to {0,1} in the ConfiguredGrantConfig of the CG2. Such RRC signaling implies that the CG group comprises the CG0, the CG1, and the CG2. When/if CGIDlist is configured, the UTO_UCI can indicate the CG PUSCHs of the CG0, the CG1, and the CG2 in the CG group.

In some embodiments, the plurality of CG configurations in the CG group has the same periodicity.

In an embodiment, in one CG group, the values of parameter periodicity in ConfiguredGrantConfig of the plurality of CG configurations are same.

In some cases, periodicities of the CG configurations in a CG group have an integer multiple relationship. For example, the CG configurations in the same CG group may have the same periodicity. As an alternative, the periodicities of the CG configurations in the same group are multiples of one of the periodicities of the CG configurations.

For example, assuming there are 3 CG configurations CG0, CG1, and CG2 in the CG group, these three CG configurations have the same value of the parameter periodicity in their own ConfiguredGrantConfig, e.g., sym5x14.

In some embodiment, periodicities of the plurality of CG configurations are multiples of one of the periodicities of the plurality of CG configurations in the CG group.

In an embodiment, in one CG group, the values of parameter periodicity in ConfiguredGrantConfig of the plurality of CG configurations has a greatest common divisor which is larger than 1.

In an embodiment, in one CG group, the values of parameter periodicity in ConfiguredGrantConfig of the plurality of CG configurations are equal to the greatest common divisor which is larger than 1.

In an embodiment, in one CG group, the values of parameter periodicity in ConfiguredGrantConfig of the plurality of CG configurations are multiples of the greatest common divisor which is larger than 1.

In an embodiment, the unit of the value of the greatest common divisor is a slot.

In an embodiment, the unit of the value of the greatest common divisor is a symbol.

In some cases, the CG configurations in a CG group have periodicities with an integer multiple relationship and their offsets is smaller than a threshold, where the threshold is determined by RRC signaling.

In some cases, the CG configurations in a CG group are configured with an indication of enabling the first signaling.

In some embodiments, the plurality of CG configurations in a CG group has the same logical channel priority in one logical channel group.

In an embodiment, the plurality of CG configurations in the group has the same parameter priority of the ul-SpecificParameters in the RRC signaling LogicalChannelConfig.
