Description

[0001] The present disclosure relates generally to wireless communications, and particularly to 5G communications.

[0002] In communications beyond 5G and 6G, a promising service is characterized by quasi-periodicity (affected by jitter), large and diverse data volumes, and strict latency requirements, such as extended reality (XR) services. In the prior art, configuration grant (CG) enables the delivery of periodic data using pre-configured resources without the need for time-consuming grant requests. To cope with the large and variable size of data packets, it is considered to use multiple CG physical uplink shared channel (PUSCH) opportunities for transmission within a period. Due to the large and diverse service characteristics of data volumes, pre-configured resources may be over-configured, which leads to resource waste and thus low resource efficiency. To this end, it is considered to use uplink control information for resource release / reclaim to improve resource efficiency. However, the HARQ (Hybrid Automatic Repeat Request) process identifier (ID) of the released / reclaimed resources is still occupied, which leads to HARQ process identifier waste.

[0003] The present disclosure relates to methods, systems, and devices for CG communication, and particularly to methods, systems, and devices for determining HARQ process IDs for CG occasions.

[0142] Figure 11 An example of a schematic diagram of a wireless network node according to an embodiment of the present disclosure is shown.

[0143] Figure 1 FIG. 1 shows a schematic diagram of configuration authorization transmission according to an embodiment of the present disclosure. Figure 1 As shown, there can be multiple CG PUSCH opportunities in a CG cycle. That is, compared with the traditional CG configuration in which there is only one CG PUSCH in a single cycle, there is more than one CG PUSCH in one cycle.

[0144] In an embodiment, once the CG is activated, the BS (e.g., gNB) will allocate the CG PUSCH to the UE based on the configured parameters (e.g., RRC parameters) and the scheduling parameters (e.g., time domain allocation, frequency domain allocation, MCS level, etc.) in the activation signaling (RRC or DCI).

[0145] In an implementation, the process of configuring CG can be simply divided into:

[0146] Step 0: Parameter configuration

[0147] Step 1: Determine the transmission timing

[0148] Step 2: HARQ (Hybrid Automatic Repeat Request) process ID determination

[0149] Step 3: Resource Configuration

[0150] In the above process, steps 1 and 2 are determined by configured parameters, and step 3 is determined by scheduling parameters.

[0151] Regarding transmission opportunity determination, all available transmission opportunities are numbered and their symbol / slot positions can be derived as follows:

[0152] Type 1CG (RRC activation)

[0153] After configuring uplink grants for Grant Type 1, the MAC entity shall sequentially consider the Nth (N>=0) uplink grant occurring on symbols for which:

[0154] [(SFN×numberOfSlotsPerFrame×numberOfSymbolsPerSlot)+(slot number in the frame×numberOfSymbolsPerSlot)+symbol number in the slot]=

[0155] (timeReferenceSFN×numberOfSlotsPerFrame×numberOfSymbolsPerSlot+timeDomainOffset×numberOfSymbolsPerSlot+S+N×periodicity)modulo(1024×numberOfSlotsPerFrame×numberOfSymbolsPerSlot)

[0156] Type 2CG (DCI activated)

[0157] After configuring uplink grants for grant type 2, the MAC entity shall sequentially consider the Nth (N>=0) uplink grant occurring on symbols for which:

[0158] [(SFN×numberOfSlotsPerFrame×numberOfSymbolsPerSlot)+(slot number in the frame×numberOfSymbolsPerSlot)+symbol number in the slot]=

[0159] [(SFNstart time×numberOfSlotsPerFrame×numberOfSymbolsPerSlot+slotstart time×numberOfSymbolsPerSlot+symbolstart time)+N×periodicity]modulo(1024×numberOfSlotsPerFrame×numberOfSymbolsPerSlot)

[0160] The HARQ process ID for each transmission opportunity is determined according to the time domain position of the transmission opportunity.

[0161] For an uplink grant configured with neither harq-ProcID-Offset2 nor cg-RetransmissionTimer configured, the HARQ process ID associated with the first symbol of the UL transmission is derived from the following equation:

[0162] HARQ process ID=[floor(CURRENT_symbol / periodicity)]modulo nrofHARQ-Processes

[0163] For an uplink grant configured with harq-ProcID-Offset2, the HARQ process ID associated with the first symbol of the UL transmission is derived from the following equation:

[0164] HARQ process ID=[floor(CURRENT_symbol / periodicity)]modulo nrofHARQ-Processes+harq-ProcID-Offset2

[0165] "CURRENT_symbol" is the result of the transmission timing determination formula.

[0166] Figure 2 A schematic diagram of configuring grant transmission according to an embodiment of the present disclosure is shown. In this embodiment, the HARQ process ID of the first transmission opportunity in a time period is determined by the first formula, and the HARQ process IDs of the remaining transmission opportunities in the time period are based on the HARQ process ID of the first transmission opportunity.

[0167] Figure 3 A schematic diagram of configuring grant transmission according to an embodiment of the present disclosure is shown. In this embodiment, the HARQ process ID of a transmission opportunity within a time period is determined by a first formula.

[0168] Figure 4 FIG. 1 shows a schematic diagram of configuration authorization transmission according to an embodiment of the present disclosure. Figure 4 In the present disclosure, the HARQ process ID of a transmission opportunity is initially determined by a higher layer parameter. After the UE sends the first signaling indicating an unused transmission opportunity, the HARQ process ID may be modified. In the present disclosure, a transmission opportunity used / configured for data transmission is referred to as a "used transmission opportunity", and a transmission opportunity not used / configured for data transmission is referred to as an "unused transmission opportunity". For example, in Figure 4In the first time period of , the 0th, 1st and 2nd transmission opportunities are used transmission opportunities, while the 3rd and 4th transmission opportunities are unused transmission opportunities. In an embodiment, the first signaling may further explicitly or implicitly indicate an unused HARQ process ID (i.e., a HARQ process ID configured for an unused CG opportunity). Based on the released HARQ process ID determined by the first signaling, the HARQ process ID of the transmission opportunity in the subsequent time opportunity may be modified. For example, Figure 4 As shown, the HARQ IDs configured for the unused transmission opportunities (ie, the third and fourth transmission opportunities) in the first time period may be reused / recycled for the transmission opportunities in the second time period.

[0169] Note that in Figure 4 In the embodiment, the HARQ process ID for the transmission opportunity in the third time period is determined by a default method (for example, the same method as determining the HARQ process ID for the transmission opportunity in the first time period) because the first signaling is not sent in the second time period.

[0170] In an embodiment, the UE may:

[0171] receiving control signaling from a network node;

[0172] determining at least one first HARQ process ID for a plurality of transmission opportunities based on a first formula and control signaling;

[0173] sending first signaling associated with a transmission opportunity;

[0174] A plurality of second HARQ process IDs for the plurality of transmission opportunities are determined based on the first signaling.

[0175] In an embodiment, the first signaling may be used for transmission opportunities within a first time period, and the second HARQ process ID may be used for transmission opportunities within a second time period.

[0176] In an embodiment, the first time period and the second time period are consecutive time periods.

[0177] In the embodiment, the first formula is not limited to the formula.

[0178] The following items will be discussed further in the subsequent implementation:

[0179] - interpretation of control signalling;

[0180] - Explanation of transmission timing;

[0181] - interpretation of the first signalling;

[0186] In an embodiment, the RRC signaling may be ConfiguredGrantConfig.

[0187] In some embodiments, the control signaling may include downlink control information (DCI) signaling.

[0188] In an embodiment, DCI signaling is used for CG activation, such as DCI format 0_0 / 0_1 / 0_2 scrambled by CS-RNTI.

[0189] Explanation of transmission timing

[0190] In some embodiments, there is (only) one transmission opportunity in a time period, and this transmission opportunity is used to configure the grant transmission. In these embodiments, the transmission opportunity may be periodic.

[0191] In some embodiments, there are multiple transmission opportunities within a single time period, and the transmission opportunities are used to configure the grant transmission. In these embodiments, the time period can be periodic.

[0192] In an embodiment where a single time period includes multiple transmission opportunities, a portion of the transmission opportunities within a time period is used for data transmission, and another portion of the transmission opportunities within the same time period is not used for data transmission. In this disclosure, transmission opportunities used / configured for data transmission are referred to as "used transmission opportunities," and transmission opportunities not used / configured for data transmission are referred to as "unused transmission opportunities."

[0193] In some implementations, the length of the time period comprises a number of symbols.

[0194] In an embodiment, the number of symbols refers to the (symbol) duration covering multiple transmission opportunities.

[0195] In some implementations, the length of the time period comprises a number of time slots.

[0196] In an embodiment, the number of time slots refers to the duration (of time slots) covering multiple transmission opportunities.

[0197] In some implementations, the length of the time period comprises a number of milliseconds.

[0198] In an embodiment, the number of milliseconds refers to a duration (in milliseconds) covering multiple transmission opportunities.

[0199] In some implementations, the length of the time period comprises one period for configuration authorization.

[0200] In an embodiment, the length of the time period comprises a multiple of the cycles of the configuration authorization.

[0201] In an embodiment, the length of the time period is the period of the configuration grant configured by periodicity in RRC signaling configuredGrantConfig.

[0202] Explanation of the first signaling

[0203] In some embodiments, the first signaling includes at least one of the following:

[0204] - Uplink Control Information (UCI) signaling;

[0205] -MAC CE signaling.

[0206] In an embodiment, the UCI signaling is CG-UCI signaling.

[0207] In an embodiment, the UCI signaling is dedicated UCI signaling.

[0208] In some embodiments, the first signaling includes transmission opportunity release information of at least one unused transmission opportunity that was not used for data transmission within the first time period.

[0209] In an embodiment, the transmission opportunity release information includes the number of unused transmission opportunities in one or more time periods.

[0210] In an embodiment, the transmission opportunity release information includes the duration of unused transmission opportunities in one or more time periods.

[0211] In an embodiment, the transmission opportunity release information includes an indication (eg, a bitmap) for indicating whether the transmission opportunities in one or more time periods are used or unused.

[0212] In an embodiment, the indication (eg, a bitmap) included in the transmission opportunity release information is configured to indicate whether the transmission opportunities within one or more time periods are unused.

[0213] In some embodiments, the first signaling includes transmission opportunity release information of unused transmission opportunities not used for data transmission in the first time period and information of a first HARQ process ID of the unused transmission opportunities not used for data transmission in the first time period.

[0214] In an embodiment, the released transmission opportunity information indicates a HARQ process ID associated with the released / unused transmission opportunity.

[0215] For example, in Figure 4 In the example, the third and fourth transmission opportunities of the corresponding HARQ process IDs 3 and 4 are unused. In this embodiment, the first signaling may report the HARQ process IDs 3 and 4 to the base station.

[0216] In some implementations, the first signaling is sent in the CG PUSCH.

[0217] In an embodiment, the first signaling is sent in the first (1st) configured CG PUSCH in one or more time periods.

[0218] In an embodiment, the first signaling is sent in the first (1st) valid CG PUSCH in one or more time periods. The valid CG PUSCH refers to a CG PUSCH that carries data.

[0219] In an embodiment, the first signaling is sent in all valid CG PUSCHs in one or more time periods.

[0220] In an embodiment, the first signaling is sent in a preconfigured CG PUSCH in one or more time periods, wherein the preconfigured CG PUSCH is determined by at least RRC signaling.

[0221] In an embodiment, if the PUSCH collides with / overlaps with the CG PUSCH originally configured / used to send UCI signaling in the time domain, the first signaling is sent in the PUSCH scheduled by the DCI signaling.

[0222] In an embodiment, if the PUSCH collides with / overlaps with the CG PUSCH originally configured / used to send UCI signaling in the frequency domain, the first signaling is sent in the PUSCH scheduled by the DCI signaling.

[0223] In an embodiment, if the PUSCH collides with / overlaps the CG PUSCH originally configured / used to send the first signaling in both the time domain and the frequency domain, the first signaling is sent in the PUSCH scheduled by the DCI signaling.

[0224] In an embodiment, if the CG PUSCH configured to transmit the first signaling is erroneously decoded, the first signaling is transmitted in a PUSCH scheduled by DCI signaling. In addition, the PUSCH scheduled by DCI may be a retransmission PUSCH for the CG PUSCH.

[0225] In an embodiment, if the CG PUSCH configured to send the first signaling is erroneously decoded, the first signaling is sent in the next CG PUSCH within the same time period.

[0226] Method for determining the first HARQ process ID of transmission opportunity

[0227] In some embodiments, the valid transmission opportunity is a transmission opportunity that does not overlap with a physical uplink shared channel (PUSCH) scheduled by DCI signaling.

[0228] In some implementations, determining the first HARQ process ID of the transmission opportunity based on the first formula includes:

[0229] The HARQ process ID of the first transmission opportunity in each time period is determined based on the first formula, and the remaining transmission opportunities are determined based on the HARQ process ID of the first transmission opportunity in a time period.

[0230] In an embodiment, determining the first HARQ process ID of the first (valid) transmission opportunity in each time period based on the first formula includes calculating the HARQ process ID of the (valid) transmission opportunity using the first formula.

[0231] In an embodiment, determining the remaining transmission opportunities based on the HARQ process ID of the first transmission opportunity in a time period is to set the same HARQ process ID as the HARQ process ID of the first transmission opportunity in the time period for all remaining transmission opportunities.

[0232] For example, the HARQ process IDs of the remaining transmission opportunities within the time period are determined to be equal to the HARQ process ID of the first transmission opportunity within the time period.

[0233] In an embodiment, the remaining transmission opportunities in each time period are determined based on the HARQ process ID of the first transmission opportunity in each time period, including setting HARQ process IDs in an increasing order starting from the HARQ process ID of the first transmission opportunity in the time period for the remaining transmission opportunities.

[0234] Alternatively, the HARQ process IDs of the remaining transmission opportunities within the time period are determined to be arranged in ascending order starting from the HARQ process ID of the first transmission opportunity within the time period. For example, the HARQ process ID of the second transmission opportunity within the time period is equal to the HARQ process ID of the first transmission opportunity within the time period plus 1, the HARQ process ID of the third transmission opportunity within the time period is equal to the HARQ process ID of the first transmission opportunity within the time period plus 2, and so on.

[0235] In an embodiment, the remaining transmission opportunities do not overlap with the physical uplink shared channel (PUSCH) scheduled by DCI signaling. That is, the remaining transmission opportunities do not conflict with the PUSCH scheduled by DCI signaling.

[0236] In some implementations, determining the first HARQ process ID of the transmission opportunity based on the first formula includes:

[0237] The (all) HARQ process IDs of the transmission opportunities in each time period are determined based on the first formula.

[0238] In an embodiment, determining the first HARQ process ID of the (valid) transmission opportunities in each time period based on the first formula includes calculating the HARQ process IDs of all (valid) transmission opportunities in each time period using the first formula.

[0239] In some implementations, the first formula for determining the HARQ process ID of a transmission opportunity is associated with at least one of the following:

[0240] -Time position information of the starting symbol of the transmission opportunity;

[0241] - Period information (of a time period);

[0242] - Number of HARQ process IDs;

[0243] -Offset information.

[0244] In an embodiment, the offset information is determined by or based on the number of transmission opportunities in a time period. In this case, the offset information is a set of integer values ​​ranging from 0 to the number of transmission opportunities minus 1.

[0245] For example, if the number of transmission opportunities is 4, the offset information may be {0, 1, 2, 3}, or the offset information may be {2, 3, 0, 1} obtained by performing a 2-unit cyclic shift based on the ascending order set {0, 1, 2, 3}.

[0246] In an embodiment, the offset information is determined by or based on the number of first HARQ process IDs. In this case, the offset information is a set of integer values ​​ranging from 0 to the number of first HARQ process IDs minus 1.

[0247] For example, if the number of HARQ process IDs is 8, the offset information may be {0, 1, 2, 3, 4, 5, 6, 7}. Alternatively, the offset information may be {4, 5, 6, 7, 0, 1, 2, 3} obtained by performing a 4-unit cyclic shift based on the ascending sequence set {0, 1, 2, 3, 4, 5, 6, 7}.

[0248] In an embodiment, the first formula is associated with time position information of a start symbol of a transmission opportunity, period information determined by control signaling, and the number of first HARQ process IDs.

[0249] In some implementations, the first formula can be expressed as:

[0250] HARQ process ID=[floor(CURRENT_symbol / P)]modulo nrofHARQProcesses(+harq-ProcID-Offset2)

[0251] Wherein, CURRENT_symbol represents the time position information of the starting symbol of the transmission opportunity, P represents the period information determined by the control signaling, and nrofHARQ processes represents the number of first HARQ process IDs.

[0252] Alternatively, the period information P is a time period length indicating a period of configuration authorization, for example,

[0253] HARQ process ID=[floor(CURRENT_symbol / periodicity)]modulonrofHARQProcesses(+harq-ProcID-Offset2)

[0254] Alternatively, the period information P is the quotient of dividing the time period length by the number of transmission opportunities within a time period, for example,

[0255] HARQ process ID=[floor(CURRENT_symbol / periodicity / N)]modulonrofHARQProcesses(+harq-ProcID-Offset2)),

[0256] Where N is the number of transmission opportunities in a time period, when the length of the time period is the period of the configuration grant, or

[0257] HARQ process ID=[floor(CURRENT_symbol / D / N)]modulo nrofHARQProcesses(+harq-ProcID-Offset2),

[0258] Where D is the number of symbols covering multiple transmission opportunities, and the length of the time period is the duration of the symbols covering multiple transmission opportunities.

[0259] In an embodiment, the first formula is associated with time position information of a start symbol of a transmission opportunity, period information determined by control signaling, the number of first HARQ process IDs, and offset information.

[0260] In some implementations, the first formula can be expressed as:

[0261] HARQ process ID=[floor(CURRENT_symbol / P)+t i ]modulo nrofHARQProcesses(+harq-ProcID-Offset2),

[0262] Among them, t i Represents a value in the offset information. The offset information values ​​are used one by one, that is, i = mod(J, N) or i = mod(J, N) or i = mod(J, nrofHARQProcesses), where J represents the Jth transmission opportunity or the Jth time period. In addition, P = periodicity), P = periodicity / N, or P = D / N.

[0263] Alternatively, the first formula can be expressed as:

[0264] HARQ process ID=[floor(CURRENT_symbol / Periodicity)+t i ]modulonrofHARQProcesses(+harq-ProcID-Offset2)

[0265] Alternatively, the first formula can be expressed as:

[0266] HARQ process ID=[floor(CURRENT_symbol / periodicity / N)+t i ]modulonrofHARQProcesses(+harq-ProcID-Offset2),

[0267] Alternatively, the first formula can be expressed as:

[0268] HARQ process ID=[floor(CURRENT_symbol / D / N)+t i ]modulo nrofHARQProcesses(+harq-ProcID-Offset2)

[0269] Method for determining the second HARQ process ID of transmission timing

[0270] In some embodiments, the HARQ process ID group determined by the first signaling includes a first HARQ process ID of an unused transmission opportunity that is not used for data transmission within the first time period.

[0271] For example, Figure 4 As shown, the unused transmission opportunities are the 3rd and 4th transmission opportunities of the corresponding HARQ process ID = 3 and HARQ process ID = 4. Therefore, the HARQ process ID group is {3, 4}.

[0272] In some implementations, determining the second HARQ process ID of the transmission opportunity based on the first signaling includes:

[0273] The second HARQ process ID of the first (valid) transmission opportunity in a time period is determined based on the HARQ process ID group, and the second HARQ process IDs of the remaining transmission opportunities are determined based on the second HARQ process ID of the first (valid) transmission opportunity in a time period.

[0274] In an embodiment, determining the second HARQ process ID of the first (valid) transmission opportunity within a time period based on the HARQ process ID group includes selecting a predefined HARQ process ID from the HARQ process ID group.

[0275] In an embodiment, the predefined HARQ process ID is the largest HARQ process ID in the HARQ process ID group.

[0276] Alternatively, the predefined HARQ process ID is the smallest HARQ process ID in the HARQ process ID group.

[0277] Alternatively, the predefined HARQ process ID is a random HARQ process ID in the HARQ process ID group.

[0278] Alternatively, the predefined HARQ process ID is the first HARQ process ID in the HARQ process ID group.

[0279] Alternatively, the predefined HARQ process ID is a HARQ process ID following the last HARQ process ID in the HARQ process ID group.

[0280] For example, the second HARQ process ID of the first (valid) transmission opportunity in a time period is the first HARQ process ID in the second HARQ process ID group. In an embodiment where the HARQ process ID group is {ID1, ID2, ID3}, the first HARQ process ID is ID1.

[0281] In an embodiment, the second HARQ process IDs of the remaining transmission opportunities are determined based on the second HARQ process ID of the first (valid) transmission opportunity within a time period, including setting a HARQ process ID that is the same as the second HARQ process ID of the first (valid) transmission opportunity within the time period for all transmission opportunities within the time period.

[0282] For example, the second HARQ process IDs of the remaining transmission opportunities within the time period may be determined to be equal to the second HARQ process ID of the first (valid) transmission opportunity within the time period.

[0283] In an embodiment, the second HARQ process IDs of the remaining transmission opportunities are determined based on the second HARQ process ID of the first (valid) transmission opportunity within a time period, including setting the HARQ process IDs for the remaining transmission opportunities within the time period in an increasing order starting from the HARQ process ID of the first (valid) transmission opportunity within the time period.

[0284] For example, the HARQ process IDs of the remaining transmission opportunities within the time period are determined to be arranged in ascending order starting from the second HARQ process ID of the first (valid) transmission opportunity within the time period.

[0285] In an embodiment, the remaining transmission opportunities are valid transmission opportunities that do not overlap with the PUSCH scheduled by DCI signaling.

[0286] Figure 5 FIG. 1 shows a schematic diagram of configuration authorization transmission according to an embodiment of the present disclosure. Figure 5 In the embodiment, there are 5 transmission opportunities in a time period, and the total number of HARQ process IDs is also 5. In the first time period, the first HARQ process ID of the transmission opportunity is determined to be {0, 1, 2, 3, 4}. In this embodiment, the 3rd and 4th transmission opportunities in the 1st time period are unused transmission opportunities. Thus, the HARQ process ID group is {3, 4}, that is, the HARQ process IDs corresponding to the 3rd and 4th transmission opportunities in the 1st time period. For the determination of the HARQ process ID of the transmission opportunity in the 2nd time period, the HARQ process ID of the 1st transmission opportunity in the 2nd time period is set to the 1st HARQ process ID in the HARQ process ID group, that is, HARQ process ID = 3. In Figure 5, the HARQ process IDs of the remaining four transmission opportunities in the second time period may all be set to 3. Alternatively, the HARQ process IDs of the remaining four transmission opportunities in the second time period may be set to start from HARQ process ID=3 (i.e., {4, 0, 1, 2}) and arranged in ascending order.

[0287] In some embodiments, the HARQ process ID group determined by the first signaling includes a second HARQ process ID of an unused transmission opportunity not used for data transmission in the second time period.

[0288] Figure 6 FIG. 1 shows a schematic diagram of configuration authorization transmission according to an embodiment of the present disclosure. Figure 6 In the second time period, the HARQ process ID is Figure 5 The embodiment shown is determined. Figure 6 The previously determined second HARQ process ID is included in the HARQ process ID group indicated by the first signaling in the second time period to determine the HARQ process ID of the transmission opportunity in the third time period.

[0289] In some implementations, determining the second HARQ process ID of the transmission opportunity based on the first signaling includes:

[0290] The second HARQ process ID of the first (valid) transmission opportunity in a time period is determined based on the HARQ process ID group, and the second HARQ process IDs of the remaining transmission opportunities are determined based on the second HARQ process ID of the first (valid) transmission opportunity in a time period.

[0291] In an embodiment, determining the second HARQ process ID for the first (valid) transmission opportunity within a time period based on the HARQ process ID group includes selecting a predefined HARQ process ID from the HARQ process ID group.

[0292] In an embodiment, the predefined HARQ process ID is the largest HARQ process ID in the HARQ process ID group.

[0293] Alternatively, the predefined HARQ process ID is the smallest HARQ process ID in the HARQ process ID group.

[0294] Alternatively, the predefined HARQ process ID is a random HARQ process ID in the HARQ process ID group.

[0295] Alternatively, the predefined HARQ process ID is the first HARQ process ID in the HARQ process ID group.

[0296] Alternatively, the predefined HARQ process ID is a HARQ process ID following the last HARQ process ID in the HARQ process ID group.

[0297] For example, the second HARQ process ID of the first (valid) transmission opportunity in a time period is the first HARQ process ID in the HARQ process ID group. Assuming the HARQ process ID group is {ID1, ID2, ID3}, the first HARQ process ID is ID1.

[0298] In an embodiment, the second HARQ process IDs of the remaining transmission opportunities are determined based on the second HARQ process ID of the first (valid) transmission opportunity within a time period, including: for all transmission opportunities within the time period, setting the same HARQ process ID as the second HARQ process ID of the first (valid) transmission opportunity within the time period.

[0299] For example, the second HARQ process IDs of the remaining transmission opportunities within the time period may be determined to be equal to the second HARQ process ID of the first (valid) transmission opportunity within the time period.

[0300] In an embodiment, the second HARQ process IDs of the remaining transmission opportunities are determined based on the second HARQ process ID of the first (valid) transmission opportunity within a time period, including: for the remaining transmission opportunities within the time period to the remaining transmission opportunities, the HARQ process IDs are set in an increasing order starting from the HARQ process ID of the first (valid) transmission opportunity within the time period.

[0301] For example, the HARQ process IDs of the remaining transmission opportunities within the time period are determined to be arranged in ascending order starting from the second HARQ process ID of the first transmission opportunity within the time period.

[0302] In an embodiment, the remaining transmission opportunities are valid transmission opportunities that do not overlap with the PUSCH scheduled by DCI signaling.

[0303] exist Figure 6 In , 5 transmission opportunities are configured in one time period, and the total number of HARQ process IDs is also 5. Figure 5In the embodiment, in the second time period, the first HARQ process ID of the transmission opportunity is determined to be {3, 4, 0, 1, 2}. The 9th transmission opportunity is an unused transmission opportunity in the second time period. Therefore, the HARQ process ID group is {2}, that is, the corresponding HARQ process ID of the 9th transmission opportunity in the second time period. For the determination of the HARQ process ID of the transmission opportunity in the third time period, the HARQ process ID of the first transmission opportunity in the third time period is set to the first HARQ process ID in the HARQ process ID group, that is, HARQ process ID = 2. The HARQ process IDs of the remaining four transmission opportunities in the third time period can all be set to 2 or arranged in ascending order starting from HARQ process ID = 2 (such as {3, 4, 0, 1}).

[0304] In some embodiments, the HARQ process ID group determined by the first signaling includes a first HARQ process ID for a transmission opportunity used for data transmission within the first time period.

[0305] Figure 7 FIG. 1 shows a schematic diagram of configuration authorization transmission according to an embodiment of the present disclosure. Figure 7 , the transmission opportunities used in the first time period are the 0th, 1st and 2nd transmission opportunities with corresponding HARQ process IDs 0, 1 and 2. In this embodiment, the HARQ process ID group is {0, 1, 2}.

[0306] In some implementations, determining the second HARQ process ID of the transmission opportunity based on the first signaling includes:

[0307] The second HARQ process ID of the first (valid) transmission opportunity in a time period is determined based on the HARQ process ID group, and the second HARQ process IDs of the remaining transmission opportunities are determined based on the second HARQ process ID of the first transmission opportunity in a time period.

[0308] In an embodiment, determining the second HARQ process ID of the first (valid) transmission opportunity within a time period based on the HARQ process ID group includes selecting a predefined HARQ process ID from the HARQ process ID group.

[0309] In an embodiment, the predefined HARQ process ID is the largest HARQ process ID in the HARQ process ID group.

[0310] Alternatively, the predefined HARQ process ID is the smallest HARQ process ID in the HARQ process ID group.

[0311] Alternatively, the predefined HARQ process ID is a random HARQ process ID in the HARQ process ID group.

[0312] Alternatively, the predefined HARQ process ID is the first HARQ process ID in the HARQ process ID group.

[0313] Alternatively, the predefined HARQ process ID is a HARQ process ID following the last HARQ process ID in the HARQ process ID group.

[0314] For example, the second HARQ process ID of the first (valid) transmission opportunity in a time period is the HARQ process ID following the last HARQ process ID in the HARQ process ID group. In an embodiment where the HARQ process ID group is {ID1, ID2, ID3}, the HARQ process ID following the last HARQ process ID is [(ID3+1) modulo nrofHARQProcesses], where nrofHARQProcesses is the total number of HARQ process IDs.

[0315] In an embodiment, the second HARQ process IDs of the remaining transmission opportunities are determined based on the second HARQ process ID of the first (valid) transmission opportunity within a time period, including setting a HARQ process ID that is the same as the second HARQ process ID of the first (valid) transmission opportunity within the time period for all transmission opportunities within the time period.

[0316] For example, the second HARQ process IDs of the remaining transmission opportunities within the time period may be determined to be equal to the second HARQ process ID of the first (valid) transmission opportunity within the time period.

[0317] In an embodiment, the second HARQ process IDs of the remaining transmission opportunities are determined based on the second HARQ process ID of the first (valid) transmission opportunity within a time period, including setting the HARQ process IDs in ascending order starting from the HARQ process ID of the first (valid) transmission opportunity within the time period for the remaining transmission opportunities within the time period.

[0318] For example, the HARQ process IDs of the remaining transmission opportunities within the time period are determined to be arranged in ascending order starting from the second HARQ process ID of the first (valid) transmission opportunity within the time period.

[0319] In an embodiment, the remaining transmission opportunities are valid transmission opportunities that do not overlap with the PUSCH scheduled by DCI signaling.

[0320] Figure 7 FIG. 1 shows a schematic diagram of configuration authorization transmission according to an embodiment of the present disclosure. Figure 7In , 5 transmission opportunities are configured in one time period, and the total number of HARQ process IDs is also 5. Figure 7 In the first time period of the transmission opportunity, the first HARQ process ID of the transmission opportunity is determined to be {0, 1, 2, 3, 4}, wherein the 0th, 1st and 2nd transmission opportunities are the transmission opportunities used for transmitting data in the first time period. In this embodiment, the HARQ process ID group is {0, 1, 2}, i.e., the corresponding HARQ process IDs of the 0th, 1st and 2nd transmission opportunities in the first time period. For the determination of the HARQ process ID of the transmission opportunity in the second time period, the HARQ process ID of the 1st transmission opportunity in the second time period is set to the HARQ process ID after the last HARQ process ID in the HARQ process ID group, i.e., HARQ process ID=3. The HARQ process IDs of the remaining 4 transmission opportunities in the second time period can all be set to 3 or arranged in ascending order starting from HARQ process ID=3 (such as {4, 0, 1, 2}).

[0321] In some embodiments, the HARQ process ID group determined by the first signaling includes a second HARQ process ID for a transmission opportunity used for data transmission within the second time period.

[0322] For example, in Figure 8 , the transmission opportunities used in the second time period are the 5th, 6th, 7th and 8th transmission opportunities with corresponding HARQ process IDs = 3, 4, 0, 1. Therefore, the HARQ process ID group indicated by the first signaling is {3, 4, 0, 1}.

[0323] In some implementations, determining the second HARQ process ID of the transmission opportunity based on the first signaling includes:

[0324] The second HARQ process ID of the first (valid) transmission opportunity in a time period is determined based on the HARQ process ID group, and the second HARQ process IDs of the remaining transmission opportunities are determined based on the second HARQ process ID of the first (valid) transmission opportunity in a time period.

[0325] In an embodiment, determining the second HARQ process ID of the first (valid) transmission opportunity within a time period based on the HARQ process ID group includes selecting a predefined HARQ process ID from the HARQ process ID group.

[0326] In an embodiment, the predefined HARQ process ID is the largest HARQ process ID in the HARQ process ID group.

[0327] Alternatively, the predefined HARQ process ID is the smallest HARQ process ID in the HARQ process ID group.

[0328] Alternatively, the predefined HARQ process ID is a random HARQ process ID in the HARQ process ID group.

[0329] Alternatively, the predefined HARQ process ID is the first HARQ process ID in the HARQ process ID group.

[0330] Alternatively, the predefined HARQ process ID is a HARQ process ID following the last HARQ process ID in the HARQ process ID group.

[0331] For example, the second HARQ process ID for the first (valid) transmission opportunity within a time period is the HARQ process ID following the last HARQ process ID in the second HARQ process ID group. Assume the HARQ process ID group is {ID1, ID2, ID3}. The HARQ process ID following the last HARQ process ID is [(ID3+1) modulo nrofHARQProcesses], where nrofHARQProcesses is the total number of HARQ process IDs.

[0332] In an embodiment, the second HARQ process IDs of the remaining transmission opportunities are determined based on the second HARQ process ID of the first (valid) transmission opportunity within a time period, including setting a HARQ process ID that is the same as the second HARQ process ID of the first (valid) transmission opportunity within the time period for all transmission opportunities within the time period.

[0333] For example, the second HARQ process IDs of the remaining transmission opportunities within the time period may be determined to be equal to the second HARQ process ID of the first (valid) transmission opportunity within the time period.

[0334] In an embodiment, the second HARQ process IDs of the remaining transmission opportunities are determined based on the second HARQ process ID of the first (valid) transmission opportunity within a time period, including setting the HARQ process IDs for the remaining transmission opportunities within the time period in an increasing order starting from the HARQ process ID of the first (valid) transmission opportunity within the time period.

[0335] For example, the HARQ process IDs of the remaining transmission opportunities within the time period are determined to be arranged in ascending order starting from the second HARQ process ID of the first transmission opportunity within the time period.

[0336] In an embodiment, the remaining transmission opportunities are valid transmission opportunities that do not overlap with the PUSCH scheduled by DCI signaling.

[0337] Figure 8 FIG. 1 shows a schematic diagram of configuration authorization transmission according to an embodiment of the present disclosure. Figure 8 In , 5 transmission opportunities are configured in one time period, and the total number of HARQ process IDs is also 5. Figure 7 In an implementation manner, in the second time period, the second HARQ process ID of the transmission opportunity is determined to be {3, 4, 0, 1, 2}. The 5th, 6th, 7th and 8th transmission opportunities are the transmission opportunities used to transmit data in the second time period. In this implementation manner, the HARQ process ID group is {3, 4, 0, 1}, which are the corresponding HARQ process IDs of the 5th, 6th, 7th and 8th transmission opportunities in the second time period, respectively. For the determination of the HARQ process ID of the transmission opportunity in the third time period, the HARQ process ID of the first transmission opportunity in the second time period is set to the HARQ process ID after the last HARQ process ID in the HARQ process ID group, that is, HARQ process ID = (1+1) modulo 5 = 2. In addition, the HARQ process IDs of the remaining 4 transmission opportunities in the third time period can all be set to 2. Or they may be arranged in increasing order starting from HARQ process ID=2 (such as {3, 4, 0, 1}).

[0338] In some implementations, determining the second HARQ process ID of the transmission opportunity based on the first signaling includes:

[0339] The second HARQ process ID of the first (valid) transmission opportunity in a time period is determined based on the HARQ process ID group, and the second HARQ process IDs of the remaining transmission opportunities are determined based on the second HARQ process ID of the first (valid) transmission opportunity in a time period.

[0340] In an embodiment, determining the second HARQ process ID for the first (valid) transmission opportunity within a time period based on the HARQ process ID group includes selecting a predefined HARQ process ID from the HARQ process ID group, and adding the predefined HARQ process ID and an offset HARQ process ID, wherein the offset HARQ process ID is determined by at least RRC signaling.

[0341] In an embodiment, the offset HARQ process ID is different in each cycle. For example, the offset HARQ process ID is arranged in increasing order in each cycle.

[0342] In an embodiment, the value range of the offset HARQ process ID is from 0 to the number of HARQ process IDs configured by RRC signaling.

[0343] In an embodiment, offsetting the HARQ process ID is used to cyclically shift the HARQ process ID of the transmission opportunity.

[0344] The following process is the same as the above embodiment.

[0345] In some implementations, determining the second HARQ process ID of the transmission opportunity based on the first signaling includes:

[0346] The second HARQ process IDs of the first K (valid) transmission opportunities within a time period are determined based on the second HARQ process ID group, and the second HARQ process IDs of the remaining transmission opportunities are determined based on the second HARQ process IDs of the first K (valid) transmission opportunities within the time period, where K is a positive integer and K is not greater than N (i.e., the number of transmission opportunities within the time period).

[0347] In an embodiment, the second HARQ process IDs of the first K (valid) transmission opportunities in a time period are the K HARQ process IDs in the HARQ process ID group.

[0348] In an embodiment, the HARQ process ID group includes HARQ process IDs of unused transmission opportunities.

[0349] In an embodiment, the second HARQ process IDs of the remaining transmission opportunities within the time period are determined to be equal to the predefined HARQ process ID associated with the second HARQ process IDs of the first K (valid) transmission opportunities within the time period.

[0350] For example, the predefined HARQ process ID may be:

[0351] - Maximum HARQ process ID;

[0352] - Minimum HARQ process ID;

[0353] - Random HARQ process ID,

[0354] - the first HARQ process ID, or

[0355] -The last HARQ process ID.

[0356] In an embodiment, the HARQ process IDs of the remaining transmission opportunities within the time period are determined as HARQ process IDs in an increasing order starting from a predefined HARQ process ID within the HARQ process IDs of the first Kt (valid) transmission opportunities within the time period. For example, the predefined HARQ process ID may be the largest HARQ process ID in the second HARQ process ID group, the smallest HARQ process ID in the second HARQ process ID group, or a random HARQ process ID in the second HARQ process ID group.

[0357] In an embodiment, the remaining transmission opportunities do not overlap with the PUSCH scheduled by DCI signaling.

[0358] In an embodiment, the second HARQ process ID for the transmission opportunity is determined by cyclically shifting the HARQ process IDs in the first HARQ process ID group based on the first signaling.

[0359] In some implementations, determining the second HARQ process ID of the transmission opportunity based on the first signaling includes:

[0360] (All) HARQ process IDs of transmission opportunities within a time period are determined based on the second HARQ process ID group and the first formula.

[0361] In an embodiment, the first formula is associated with the time position information of the start symbol of the transmission opportunity, the period information, the number of HARQ process IDs and the offset information. This formula can refer to the above embodiment.

[0362] In an embodiment, the offset information includes an offset set including values ​​ranging from 0 to N-1 (ie, the number of transmission opportunities in a time period minus 1).

[0363] In an embodiment, the set of offsets includes a first subset of offsets and a second subset of offsets.

[0364] In an embodiment, the first offset subset includes values ​​ranging from 0 to N-1, excluding values ​​in the HARQ process ID group.

[0365] In an embodiment, the second subset of offsets includes values ​​in the HARQ process ID group.

[0366] In an embodiment, the HARQ process IDs of (valid) transmission opportunities within a time period are first determined by the first formula using the second subset of offsets, and then determined by the first formula using the first subset of offsets.

[0367] In an embodiment, the HARQ process ID group determined by the first signaling includes unused transmission opportunities (eg, Figure 6 The second HARQ process ID of the second transmission opportunity).

[0368] For example, Figure 6As shown, the HARQ process ID group includes the HARQ process IDs of unused transmission opportunities, that is, the HARQ process ID group in the second time period = {2}. Assuming that the offset information is a set of integer values ​​ranging from 0 to the number of transmission opportunities minus 1, the offset information is {3, 4, 0, 1, 2}. Then the first offset subset is {3, 4, 0, 1}, that is, the set {3, 4, 0, 1, 2} excludes 2 in the HARQ process ID group. The second offset subset is {2}. In this embodiment, the first formula can be expressed as:

[0369] HARQ process ID=[floor(CURRENT_symbol / periodicity / N)+t i ]modulonrofHARQProcesses(+harq-ProcID-Offset2)

[0370] In an embodiment, the HARQ process ID of a transmission opportunity within a time period is determined by first using the second offset subset in the first formula. i First, they are set one by one to the elements in the second offset subset, and if / after all the elements in the second offset subset are used, they are set one by one to the elements in the first offset subset. Figure 7 In the formula, HARQ process ID = [floor (CURRENT_symbol / periodicity / N) + 2] modulo nrofHARQProcesses (+harq-ProcID-Offset2), which is first used for the first transmission opportunity in the third time period (ie, the tenth transmission opportunity).

[0371] Therefore, all elements in the second offset subset are used. In the following implementation, the first formula uses the elements in the first offset subset one by one:

[0372] HARQ process ID = [floor(CURRENT_symbol / periodicity / N)+3]modulo fHARQProcesses(+harq-ProcID-Offset2), for the second transmission opportunity in the third time period (i.e., the 11th transmission opportunity);

[0373] HARQ process ID = [floor(CURRENT_symbol / periodicity / N)+4]modulo fHARQProcesses(+harq-ProcID-Offset2), for the third transmission opportunity in the third time period (i.e., the 12th transmission opportunity);

[0374] HARQ process ID = [floor(CURRENT_symbol / periodicity / N)+0]modulo fHARQProcesses(+harq-ProcID-Offset2), for the fourth transmission opportunity in the third time period (i.e., the 13th transmission opportunity);

[0375] HARQ process ID = [floor(CURRENT_symbol / periodicity / N)+1] modulo fHARQProcesses(+harq-ProcID-Offset2), which is used for the 5th transmission opportunity in the 3rd time period (ie, the 14th transmission opportunity).

[0376] In an embodiment, the HARQ process IDs of (valid) transmission opportunities within a time period are first determined by a first formula using a first subset of offsets, and then determined by a second formula using a second subset of offsets.

[0377] In an embodiment, the HARQ process ID group determined by the first signaling includes a second HARQ process ID for a transmission opportunity that is not used for data transmission within the first time period.

[0378] For example, Figure 8 As shown, the HARQ process ID group includes the HARQ process IDs of unused transmission opportunities, that is, the HARQ process ID group in the second time period = {3, 4, 0, 1}. Assuming that the offset information is a set of integer values ​​ranging from 0 to the number of transmission opportunities minus 1, in this embodiment, the offset information is {3, 4, 0, 1, 2}. Then the first offset subset is {2}, that is, the set {3, 4, 0, 1, 2} excludes {3, 4, 0, 1} in the HARQ process ID group. And the second offset subset is {2}. In this embodiment, the first formula can be expressed as:

[0379] HARQ process ID=[floor(CURRENT_symbol / periodicity / N)+t i ]modulonrofHARQProcesses(+harq-ProcID-Offset2).

[0380] In this embodiment, the HARQ process ID of the transmission opportunity within a time period is determined by first using the first offset subset by the first formula, which means that t in the first formula i First, they are set one by one to the elements in the first offset subset, and if / after all the elements of the first offset subset are used, they are set one by one to the elements in the second offset subset. Figure 8 The formula can be expressed as: HARQ process ID = [floor (CURRENT_symbol / periodicity / N) + 2] modulo nrofHARQProcesses (+harq-ProcID-Offset2), which is first used for the first transmission opportunity in the third time period (ie, the tenth transmission opportunity).

[0381] Therefore, all elements in the first offset subset are used. In the following, the elements in the second offset subset are used one by one in the first formula:

[0382] [floor(CURRENT_symbol / periodicity / N)+3]modulo nrofHARQProcesses(+harq-ProcID-Offset2) for the second transmission opportunity in the third time period (i.e., the 11th transmission opportunity);

[0383] HARQ process ID = [floor(CURRENT_symbol / periodicity / N)+4]modulo fHARQProcesses(+harq-ProcID-Offset2), for the third transmission opportunity in the third time period (i.e., the 12th transmission opportunity);

[0384] HARQ process ID = [floor(CURRENT_symbol / periodicity / N)+0]modulo fHARQProcesses(+harq-ProcID-Offset2), for the fourth transmission opportunity in the third time period (i.e., the 13th transmission opportunity);

[0385] HARQ process ID = [floor(CURRENT_symbol / periodicity / N)+1] modulo fHARQProcesses(+harq-ProcID-Offset2), which is used for the 5th transmission opportunity in the 3rd time period (ie, the 14th transmission opportunity).

[0386] The above implementation for determining the second HARQ process ID is basically intended to cyclically shift the first HARQ process ID.

[0387] In some implementations, the HARQ process ID group includes one or more first HARQ process IDs within a time period.

[0388] In some implementations, the HARQ process ID group includes one or more second HARQ process IDs within a time period.

[0389] For example, the HARQ process ID group includes the first HARQ process ID of a transmission opportunity that was not used within the previous Pv period, where Pv is a positive integer (eg, Pv=1).

[0390] For example, the HARQ process ID group includes a second HARQ process ID of a transmission opportunity that was not used within a previous Pv period, where Pv is a positive integer (eg, Pv=1).

[0391] For example, the HARQ process ID group includes the first HARQ process ID of a transmission opportunity used within the previous P period, where Pv is a positive integer (eg, Pv=1).

[0392] For example, the HARQ process ID group includes the second HARQ process ID of the transmission opportunity used in the previous P period, where Pv is a positive integer (eg, Pv=1).

[0393] In an embodiment, the first time period is a previous time period in which the first signaling is sent and the HARQ process ID of the unused transmission opportunity is obtained.

[0394] In an embodiment, the second time period is a current time period, in which the HARQ process IDs of all transmission opportunities need to be determined.

[0395] For example, in Figure 8 Alternatively, when the HARQ process ID of the transmission opportunity in the second time period needs to be determined, the first time period is the first time period and the second time period is the second time period.

[0396] Alternatively, when the HARQ process ID of the transmission opportunity in the third time period needs to be determined, the first time period is the second time period, and the second time period is the third time period.

[0397] In some implementations, when the first signaling is sent in the first time period, the second HARQ process ID overwrites the first HARQ process ID in the second time period.

[0398] In some implementations, when the first signaling is not sent in the first time period, the first HARQ process ID is used by default in the second time period.

[0399] In an embodiment, the case where the first signaling is not sent includes: the UE does not receive the scheduling DCI for retransmission within the configuredGrantTimer or the cg-retransmissionTimer.

[0400] In an embodiment, the number of HARQ process IDs in the HARQ process ID group is equal to the number of unused transmission opportunities in the previous Pv time period.

[0401] In an embodiment, the number of HARQ process IDs in the HARQ process ID group is equal to the number of transmission opportunities used in the previous Pv time period.
