FIRST SIGNALING INDICATION

In some embodiments, a first signaling includes at least one information block set, which consists of one or more information blocks. In an embodiment, one information block may include a bitmap. In an embodiment, the information block set is associated with multiple CG configurations.

In some embodiment, the information block set is associated with the plurality of CG configurations in the CG group in the time duration in an ascending order of CG configuration indexes of the plurality of CG configurations.

In an embodiment, the information blocks in the information block set is ordered firstly from the smallest CG configuration index to the largest CG configuration index in one cell, and then from the smallest cell index to the largest cell index.

In an embodiment, the information blocks in the information block set is ordered firstly from the smallest CG configuration index to the largest CG configuration index in one cell, and then from the primary cell to the secondary cell.

In some embodiment, the information block set is associated with the plurality of CG configurations in the CG group in the time duration in a descending order of CG configuration indexes of the plurality of CG configurations.

In an embodiment, the information blocks in the information block set is ordered firstly from the largest CG configuration index to the smallest CG configuration index in one cell, and then from the smallest cell index to the largest cell index.

In an embodiment, the information blocks in the information block set is ordered firstly from the largest CG configuration index to the smallest CG configuration index in one cell, and then from the primary cell to the secondary cell.

FIG. 1 shows a schematic of an information block set according to an embodiment of the present disclosure. In FIG. 1, the information block set comprises N information blocks, wherein N is greater than 3. Each information block comprises/is a bitmap. The Bitmap 1 is for a CG configuration 1, the Bitmap 2 is for a CG configuration 2, and so on. Note that a bitmap is for a CG configuration represents that this bitmap is used to indicate whether (valid) transmission occasions (e.g., (valid) CG PUSCHs (physical uplink shared channels) ) of the CG configuration is unused or not. As shown in FIG. 1, the information block set indicates that whether the (valid) transmission occasions of each of CG configurations separately. Specifically, the information block set indicates that whether the (valid) transmission occasions of multiple CG configurations are unused in an ascending order of CG configuration index. Note that the information block set can be considered as a bitmap consisting of the bitmaps of the N information blocks.

In an embodiment, each information block is associated with one CG configuration.

In an embodiment, the CG configurations are in a CG group.

In an embodiment, each block includes a bitmap for the CG configuration.

In some cases, the time duration associated with the bitmap (e.g., the period of the transmission occasions indicated by the bitmap) is the length of bitmap, which is determined by the RRC signaling nrof_UTO_UCI. In these cases, the time durations of the bitmaps in the information blocks are different. In these cases, the length of bitmaps in the formation blocks are different.

In some cases, the time duration includes O^UTO-UCI valid CG PUSCH transmission occasions, where O^UTO-UCI is determined by the RRC signaling nrof_UTO_UCI.

For example, nrof_UTO_UCI is a parameter in ConfiguredGrantConfig. As a result, each CG configuration has its own nrof_UTO_UCI. Assuming there are three CG configurations in the CG group, i.e., CG0 (CG configuration with CG configuration index 0) , CG1 and CG2, there are N = 3 information blocks in the UTO-UCI signaling, nrof_UTO_UCI is set to 1 in ConfiguredGrantConfig of CG0, nrof_UTO_UCI is set to 2 in ConfiguredGrantConfig of the CG1, while nrof_UTO_UCI is set to 2 in ConfiguredGrantConfig of the CG2. Therefore, the total bit length of the UTO-UCI is 1+2+2=5.

In some cases, the time durations of the bitmaps for corresponding CG configurations are determined by a single high layer parameter.

In some cases, the single high layer parameter is nrof_UTO_UCI-r19.

In these cases, if nrof_UTO_UCI-r19 is configured, the nrof_UTO_UCI is ignored.

In one case, the time durations of the bitmaps in the information blocks are same.

In some cases, each bitmap of the information block comprises a first sub-block and/or a second sub-block, when/if the time durations of the bitmaps for corresponding CG configurations are determined by the single high layer parameter (e.g., nrof_UTO_UCI-r19) .

In one case, one or more information blocks comprise the first sub-block and the second sub-block.

In one case, one or more information blocks comprise the first sub-block.

In one case, one or more information blocks comprise the second sub-block.

In one case, the first sub-block includes the bitmap for the corresponding CG configuration, indicating whether the transmission occasions of the corresponding CG configuration are unused or not.

In one case, the second sub-block includes the reserved bits or padding bits for the corresponding CG configuration.

In one case, the first sub-block is located at most significant bits (MSBs) of the information block and the second sub-block follows the first sub-block in the information block.

As an alternative, the second sub-block is located at the MSBs of the information block and the first sub-block follows the second sub-block in the information block.

FIG. 2 shows a schematic diagram of an information block set according to an embodiment of the present disclosure. As shown in FIG 2, the time duration of each information block (i.e., bitmap) in the information block set is set to 4 (i.e., the length of bitmaps for each information block is 4) for all the three CG configurations (i.e., CG1, CG2 and CG3) . For the CG configuration 1, there are 2 valid transmission occasions (indicated by the information block set (e.g., UTO-UCI) ) . Therefore, the first sub-block includes 2 bits within the bitmap one-to-one mapped to the transmission occasions of the CG configuration 1. In addition, the second sub-block in the bitmap for the CG configuration 1 comprises includes 2 reserved bits or 2 padding bits. Similarly, there are 3 valid transmission occasions of the CG configuration 2 (indicated by the information block set (e.g., UTO-UCI) ) . Therefore, the first sub-block within the bitmap for the CG configuration 2 includes 3 bits one-to-one mapped to the 3 transmission occasions of the CG configuration 2. In addition, the second sub-block in the bitmap for the CG configuration 2 comprises includes 1 reserved bit or 1 padding bit. There are 4 valid transmission occasions of the CG configuration 3 (indicated by the information block set (e.g., UTO-UCI) ) . Therefore, the first sub-block within the bitmap for the CG configuration 3 includes 4 bits one-to-one mapped to the 4 transmission occasions of the CG configuration 3. In this embodiment, the bitmap for the CG configuration 3 does not include the second sub-block comprising the padding bits or reserved bits.

In some cases, the information blocks have different bit lengths. For example, the bit lengths are determined by high layer parameter (s) .

In some cases, the information blocks have the same bit length or a common bit length. In an embodiment, the common bit length is determined by high layer parameter (s) .

In some cases of the information blocks having the same bit length, each information block includes a first sub-block and/or a second sub-block, wherein the first sub-block is used to indicate whether the transmission occasions are unused in the time duration of the CG configuration and the second sub-block comprises reserved bits or padding bits.

In some cases, the first sub-block starts from the MSB and the second sub-block follows the first sub-block.

In some cases, the second sub-block starts from the MSB and the first sub-block follows the second sub-block.

In some cases, the multiple CG configurations are in a CG group which is associated with a single cell, multiple cells, or multi-TRPs (transmission reception points) .

In some embodiments, the plurality of bits within the bitmap are one-to-one mapped to transmission occasions of the associated CG configuration in the time duration in an ascending order of a start time of each transmission occasion.

In some cases, bits within the bitmap have one-to-one mapping to O^UTO-UCI valid CG PUSCH transmission occasions in an ascending order of start time.

In some cases, O^UTO-UCI bits of the bitmap determined by the time duration in the information block have a one-to-one mapping to O^UTO-UCI subsequent CG-PUSCH transmission occasions for the corresponding CG configuration in an ascending order of start time of the CG-PUSCH transmission occasion.

In some cases, O^UTO-UCI bits of the bitmap determined by the time duration in information block have a one-to-one mapping to O^UTO-UCI subsequent CG-PUSCH transmission occasions for the corresponding CG configuration in the CG group in ascending order of start time of the CG PUSCH transmission occasion.

In some cases, the start time is a starting symbol of each transmission occasion in the time duration of the corresponding/associated CG configuration.

As shown in FIG. 3, the start time of the CG PUSCH transmission occasions#0 of CG configuration 1 is the 1st symbol (first symbol of Slot #0) , the start time of CG PUSCH transmission#1 of CG configuration 1 is the 15th symbol (first symbol of Slot #1) , the start time of CG PUSCH transmission#2 of CG configuration 1 is the 29th symbol (first symbol of Slot #2) , the start time of CG PUSCH transmission occasion#3 of CG configuration 1 is the 43th symbol (first symbol of Slot #3) . The bitmap indicates the transmission occasions of CG configuration 1 in ascending order of start time (1st, 15th, 29th, 43th) . The bitmap for CG configuration 1 has four bits, the first bit indicates the CG PUSCH transmission occasions #0 is unused or not, the second bit indicates the CG PUSCH transmission occasions #1 is unused or not, the third bit indicates the CG PUSCH transmission occasions #2 is unused or not, the fourth bit indicates the CG PUSCH transmission occasions #3 is unused or not. The same rule is used for the bitmap indication for CG configuration 2.

In some cases, the O^UTO-UCI bits of the bitmap i in the information block i have a one-to-one mapping to O^UTO-UCI subsequent CG-PUSCH TOs (transmission occasions) for the CG configuration with a CG index j in ascending order of start time, where i = 0, ... N, N and j is an integer. For example, N = 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16.

In some cases, a bit value of ‘0’ indicates that the UE may use the corresponding CG PUSCH TO and/or transmit CG-PUSCH in the corresponding CG PUSCH TO, and a bit value of ‘1’ indicates that the UE will not use the corresponding CG PUSCH TO and/or transmit CG-PUSCH in the corresponding CG PUSCH TO.

In some cases, the O^UTO-UCI subsequent CG-PUSCH TOs of the CG configuration exclude invalid ones where a UE does not transmit a PUSCH 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 valid CG PUSCH transmission occasions of CG configurations are the transmission occasions without the 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 the corresponding cell.

FIG. 4 shows a schematic diagram of a relationship between bitmaps and CG PUSCHs of multiple CG configurations according to an embodiment of the present disclosure. In FIG. 4, a 5-bit bitmap XYYZZ may serve as or be comprised in the first signaling (e.g., UTO-UCI) and is configured to indicate whether (valid) CG PUSCH transmission occasions of CG configurations CG1, CG2 and CG3 are unused or not. Specifically, the 1-bit information block “X” in the 5-bit bitmap XYYZZ is for the CG1, the 2-bit information block “YY” in the 5-bit bitmap XYYZZ is for the CG2 and the 2-bit information block “ZZ” in the 5-bit bitmap XYYZZ is for the CG3. That is the 5-bit bitmap XYYZZ and its sub-bitmaps may refer to the abovementioned information block set and information blocks. In this embodiment, the CG configurations CG1 to CG3 are (configured) in the same CG group. As shown in FIG. 4, the bitmap indicates whether the (valid) CG PUSCHs of the configurations CG1 to CG3 are unused first/firstly in an ascending order of the CG configuration index and secondly in an order of the start time of the CG PUSCH transmission occasion.

In some cases, the first signaling includes/is the UTO-UCI.

MULTIPLE CG CONFIGURATIONS CORRELATION

In some embodiments, a high layer signaling indicating that the first signaling is configured to indicate whether the transmission occasions of the plurality of CG configurations are unused or not.

In an embodiment, the high layer signaling is RRC signaling. For example, the RRC signaling may be named UTO_UCI_ForMultiCG or nrof_UTO_UCI-r19.

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.

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 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 RRC signaling configuring the CG group information, where CG group comprises the plurality of CG configurations. For example, the RRC signaling may be named CGgroup, CGgroupID or CorrelatedCGID.

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

For example, the name of RRC signaling is 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 a 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 configuration, 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 PUSCH transmission occasions of the CG0, the CG1 and the CG2 in the CG group 0.

In some cases, the first signaling includes UTO-UCI indicating the usage of valid CG PUSCHs belonging to multiple CG configurations, which is determined by an RRC (radio resource control) signaling.

For example, if the RRC signaling is configured, the first signaling indicates the usage of the valid CG PUSCHs belonging to multiple CG configurations. If the RRC signaling is not configured, the first signaling indicates the usage of valid CG PUSCHs belonging to single CG configuration.

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 signaling is CGIDlist or CGindexList which is is a sequence of integer. Moreover, the RRC signaling is in ConfiguredGrantConfig.

As an alternative, the CG configuration index list includes all the CG configuration indexes in the same group.

Assuming there are 3 CG configurations CG0, CG1, and CG2 in 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 configuration, it implies CG group comprises the CG0, the CG1, and the CG2. When/If the RRC signaling is configured, the UTO_UCI can indicate the usage of 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 with 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 configuration implies that the CG group comprises the CG0, the CG1 and the CG2. When/If the RRC signaling is configured, the UTO_UCI can indicate the usage of 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 have 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.
