DETAILED DESCRIPTION OF THE INVENTION

[0038] In exemplary embodiments, at least a method and apparatus is provided for scheduling retransmissions for a configured grant transmission burst using uplink grants for multiple TTIs.

[0039] In accordance with the embodiments of the invention described herein, methods are provided to improve the efficiency of configured NR-U grant operation by improving retransmission scheduling.

[0040] Some embodiments of the invention relate to the operation in the system of the new 5G radio interface (NR, new radio) in the unlicensed spectrum (NR-U), as well as possible further releases of access standards with the support of the licensed spectrum (LAA, LTE Licensed Assisted Access) . Emphasis is placed on non-grant operation, also known as configured uplink grants.

[0041] For Rel-15 NR basic operation, it is noted that in the uplink, the gNB can always dynamically allocate resources to the UE via the C-RNTI on the PDCCHs. The UE always monitors the PDCCH to find possible grants for uplink transmission when its downlink reception is enabled (activity controlled by DRX when configured).

[0042] In addition, using the configured grants, the R15 gNB can allocate uplink resources for initial HARQ transmissions to UEs. Two types of configured uplink grants are defined:

- with Type 1, the RRC directly grants the configured uplink grant (including periodicity); and/or

- with Type 2, the RRC determines the frequency of the configured uplink grant, while the PDCCH addressed to the CS-RNTI can either signal and activate the configured uplink grant or deactivate it; that is, the PDCCH addressed to the CS-RNTI ¹ uplink grant may be implicitly reused according to the periodicity determined by the RRC until deactivated.

When the configured uplink grant is active, if the UE cannot find its C-RNTI/CS-RNTI on the PDCCH(s), uplink transmission can be performed according to the configured uplink grant. Otherwise, if the UE finds its C-RNTI/CS-RNTI on the PDCCH(s), the PDCCH assignment overrides the configured uplink grant.

[0043] The CS-RNTI corresponds to the configured scheduling, and retransmissions other than repetitions are explicitly allocated via the PDCCH channel(s).

[0044] A somewhat similar mechanism is also supported in LTE where WI Release 15 (Rel-15 WI) "LTE Unlicensed Spectrum Enhancements" introduces support for autonomous UL transmissions in unlicensed spectrum (SCells with licensed spectrum enabled access) with the following key characteristics:

• UL Offline Access (AUL):

устройство UE может быть сконфигурировано посредством RRC с помощью набора подкадров и процессов HARQ, которые оно может использовать для автономных передач PUSCH;

the UE may be configured by RRC with a set of subframes and HARQ processes that it may use for autonomous PUSCH transmissions;

Операция AUL активируется и отключается с форматом DCI 0A или 4А;

AUL operation is enabled and disabled with DCI format 0A or 4A;

устройство UE пропускает выделение AUL, если в буферах UL нет данных;

the UE skips AUL assignment if there is no data in the UL buffers;

выделение PRB, MCS, а также циклический сдвиг DMRS и ортогональный код покрытия указываются для UE с активацией AUL DCI;

PRB allocation, MCS, and DMRS cyclic shift and orthogonal coverage code are indicated for UEs with AUL DCI enabled;

устройство UE указывает eNodeB вместе с каждой передачей UL идентификатор выбранного процесса HARQ, индикатор новых данных, версию избыточности, идентификатор UE, начальную и конечную точки PUSCH, а также указывает, может ли полученное устройством UE время занятости канала (СОТ, channel occupancy time) совместно использоваться с eNodeB; и/или

The UE indicates to the eNodeB with each UL transmission the selected HARQ process ID, new data indicator, redundancy version, UE ID, PUSCH start and end points, and whether the channel occupancy time (COT) received by the UE can be shared be used with eNodeB; and/or

eNodeB может предоставить UE обратную связь HARQ для процессов HARQ с поддержкой AUL, передать команду мощности и передать PMI через сообщение сигнализации управления DL, называемое AUL-DFI.

The eNodeB may provide the UE with HARQ feedback for AUL-enabled HARQ processes, transmit a power command, and transmit a PMI via a DL control signaling message called AUL-DFI.

[0045] AUL also allows configuring a set of starting positions for UEs with very fine hops within the first SC-FDMA symbol of a subframe: 16, 25, 34, 43, 52, or 61 microseconds after the subframe boundary or at the start of symbol #1. Since all UEs perform a "listen before talking" operation before transmitting AUL to determine if the channel is free, different starting points allow, for example, to prioritize transmissions for certain UEs (by assigning an earlier starting point) and reduce collisions. The transmission within the 1st symbol is not PUSCH data, but instead a very long CP extended from the next symbol #2. Basically, the CP extension is used to reserve a channel for a given UE by blocking other UEs.

[0046] The following are some of the conventions for configured NR-U grants (with some relevant parts underlined):

• CG support for both Type 1 and Type 2; and

• The following modifications to configured grant procedures are useful (not an exhaustive list):

• Removing the dependency of HARO process information on time. This can be achieved by introducing a UCI in PUSCH to carry the HARQ process ID, NDL RVID:

• The UE selects a HARQ process ID from the set of HARO IDs configured by RRC: and

• Additional information fields to be included in the UCL include at least the following:

• HARQID.

• NDI and RV,

• COT sharing information, FFS details,

• FFS: other information including UE ID;

• Introduction of Downlink Feedback Information (DFI), including pending HARQ feedback;

• Greater flexibility in resource allocation in the time domain

• For example, a bitmap approach or

• An NR Rel-15 based time domain resource allocation approach that includes {periodicity, frame offset, PUSCH start symbol and length, and K-repetition signaling},

• Additional aspects such as finer granularity in resource allocation and multiple resources over a period can be considered to increase flexibility in resource allocation in the time domain.

• Support for retransmissions without an explicit UL grant, also in CG resources.

• In the absence of feedback, the UE may not assume an ACK (but rather assume a NACK, based on some timer)

• Allowing sequential CG resources over time with no gaps between resources and non-sequential configured grant resources (not necessarily periodic) with gaps between resources

• To manage collisions between users, a set of pseudo-random starting positions are introduced with a degree of splitting into sub-symbols

• A user with a later start point will detect the earlier user when doing LBT and skip their transmission.

• To allocate resources in the time domain of a configured grant, the mechanisms in Rel-15 (both Type 1 and Type 2) are extended so that the number of allocated slots after a specified offset can be configured.

[0047] In accordance with embodiments of the present invention, the focus is on improving retransmission scheduling for CG-PUSCH transmissions so that the network can efficiently initiate a UE to retransmit data that was transmitted on CG-PUSCH resources but was not correctly received.

[0048] Unlicensed spectrum is inherently not as reliable as licensed wireless spectrum. This is because transmissions often originate from many different nodes using potentially different radio access technologies and are therefore not coordinated. This can cause bursts of interference in the working channels and random errors in data decoding. One effective way to deal with random errors is to repeat transmissions many times to increase the received energy per bit ratio and provide time domain diversity to protect against interference.

[0049] In addition to reliability, another key performance indicator (KPI, key performance indicator) for wireless services is delay. When considering uplink operation in the unlicensed spectrum, latency is a particular problem: since all nodes must normally perform a Listen Before You Talk (LBT) procedure before transmitting in the unlicensed spectrum to ensure that the channel is indeed not busy, it cannot be guaranteed that the transfer always takes place as it is supposed to. That is, each LBT procedure required before transmission increases this delay to some extent. This problem occurs in particular with scheduled uplink transmissions because the UE first needs to send a scheduling request (LBT#1), after which the gNB sends the UL grant (LBT#2) to the UE, and only after receiving the UL grant does the UE can transmit UL data (after executing one more LBT procedure, #3).

[0050] One way to reduce the delay associated with UL transmissions in unlicensed spectrum is to use configured grants. With the configured grants, the gNB can assign a UE (or typically a group of UEs) certain time-frequency resources that are periodically available and the UE is allowed to transmit in them without having to first send a scheduling request.

[0051] In an NR system with unlicensed spectrum, CG resources are assigned to UEs with RRC signaling indicating the periodicity of the CG resource burst, the duration of such a burst, and the start slot for the burst. In addition, resources may be activated or deactivated by downlink control information transmitted over the PDCCH (referred to in NR as SPS activation and SPS release). Moreover, there may be short gaps between resources to allow UEs to perform LBT before each transmission.

[0052] An example of this is shown in FIG. 1 where the periodicity is set to 10 slots and the duration of each CG resource burst is 3 slots. As shown in FIG. 1, an example of a CG-PUSCH resource configuration is shown. A burst of 6 resources, each occupying half a slot, is repeated every 10 slots with small gaps of 110 and 120 between resources to ensure LBT. In addition, as shown in FIG. 1, each slot is halved such that there are two non-overlapping PUSCH resource allocations in each slot, each having a duration of 7 symbols (including the LBT gap).

[0053] While LBT gaps are useful for ensuring uniform multiplexing of UEs in the time domain, on the other hand, in each gap, there is a possibility that a particular UE will lose the channel due to a negative LBT result. This is shown in FIG. 2. In another example, the channel may be busy at the start of a burst and become free during the duration of the burst.

[0054] As shown in FIG. 2, there are gaps 220 between all Tx transmissions 215. Thus, since the UE needs to perform LBT before each PUSCH transmission in a packet, it may not be able to transmit on all configured resources.

[0055] Typically, a UE may transmit during a plurality of PUSCH assignments in a UL CG resource packet. Unlike Rel-15 CG operation, with NR-U Rel-16 grants configured, the UE can independently select the HARQ process it uses for each CG transmission among the HARQ processes for which CG operation is enabled. This means that for a packet with few CG-PUSCH consecutive transmissions, the HARQ identifiers can in principle be in any arbitrary order. This complicates the scheduling of retransmissions of such data packets, since the gNB would have to provide a separate UL grant for scheduling each CG-PUSCH transmission, which would result in significant DL Control Channel (PDCCH) overhead. In addition, the PDCCH throughput or decoding capabilities of the UE may prevent multiple UL grants from being scheduled in a single DL slot.

[0056] In exemplary embodiments, a framework is provided to provide more flexible retransmission scheduling for configured grant PUSCH transmissions using UL grants for multiple TTIs.

[0057] One of the prior art solutions for scheduling CG-PUSCH retransmissions is the following:

- allow the UE to use autonomous retransmissions in CG-PUSCH resources after receiving a negative ACK for a given transport block via downlink feedback information (DFI):

Недостатком этого подхода является увеличенная задержка, а также возможные коллизии с каналами CG-PUSCH других UE, поскольку один и тот же ресурс CG обычно конфигурируется для множества UE;

The disadvantage of this approach is increased delay as well as possible collisions with other UEs' CG-PUSCHs since the same CG resource is typically configured for multiple UEs;

- scheduled retransmissions with regular UL grants

Это приводит к большому объему служебных данных PDCCH и/или низкой гибкости планирования из-за ограниченных возможностей UE, поскольку для каждого выделения PUSCH требуется отдельный грант; и/или

This results in high PDCCH overhead and/or low scheduling flexibility due to limited UE capabilities since a separate grant is required for each PUSCH allocation; and/or

- scheduled retransmissions with UL grants of multiple TTIs using consecutive HARQ-IDs for scheduled HARQ processes

Это часто нецелесообразно, поскольку идентификаторы процессов HARQ, которые может запланировать грант UL для множества TTI, всегда являются последовательными, в то время как идентификаторы процессов HARQ пакета передачи CG-PUSCH могут появляться в любом порядке.

This is often impractical because the HARQ process IDs that a UL grant may schedule for multiple TTIs are always sequential, while the HARQ process IDs of a CG-PUSCH transmission burst may appear in any order.

[0058] As discussed here, all three existing approaches have distinct drawbacks, and embodiments of the invention at least provide improved solutions for triggering CG-PUSCH retransmissions.

[0059] Before a detailed description of the exemplary embodiments of the invention, reference is made to FIGS. 7 to illustrate a simplified block diagram of various electronic devices suitable for use in embodiments of the present invention.

[0060] FIG. 7 shows a block diagram of one possible and non-limiting example of a system in which embodiments of the invention may be implemented. In FIG. 7, user equipment (UE) 110 is in wireless communication with wireless network 100. A UE is a wireless, typically mobile, device that can access a wireless network. UE 110 includes one or more processors 120, one or more memories 125, and one or more transceivers 130 interconnected via one or more buses 127. Each of the one or more transceivers 130 includes an Rx receiver 132 and a Tx transmitter 133. One or more buses 127 may be address, data, or control buses and may use any interconnection mechanism such as a series of lines on a motherboard or integrated circuit, optical fiber or other optical communications equipment, and the like. One or more transceivers 130 are connected to one or more antennas 128. One or more memory units 125 include computer program code 123. UE 110 includes a determination module comprising one or both of parts 140-1 and/or 140-2, which may be implemented in several ways. This determination module is an optional module and may be configured by software and/or processors to carry out the embodiments of the invention disclosed herein. These portions of the definition module may include processor configurations that may be implemented to carry out the embodiments of the invention disclosed herein. The determination module may be implemented in hardware as a determination module 140-1, for example, implemented as part of one or more processors 120. The determination module 140-1 may also be implemented in an integrated circuit or other hardware such as a field-programmable gate array. . In another example, the determination module may be implemented as a determination module 140-2, which is implemented as computer program code 123 and executed by one or more processors 120. In addition, the determination modules shown in FIG. 7 are optional and their operations may be performed by other UEs 110 as shown in FIG. 7. For example, one or more memory units 125 and computer program code 123 may be configured to cause one or more processors 120 to cause user device 110 to perform one or more operations as described herein. The UE 110 communicates with the node 170 of the radio access network (RAN, radio access network) through the wireless link 111.

[0061] RAN node 170 may be a base station that allows wireless devices such as UE 110 to access wireless network 100. For example, RAN node 170 may be a node (eg, base station) in an NR/5G network such as gNB (node that provides NR user and control layer protocol terminations towards UE 110) or ng-eNB (node that provides E-UTRA user and control layer protocol terminations towards UE 110 and connected via NG interface to core network (i.e. 5G Core (5CC))). RAN node 170 includes one or more processors 152, one or more memory units 155, one or more network interfaces (N/W I/F) 161, and one or more transceivers 160 interconnected via one or more buses 157. Each of one or more transceivers 160 includes an Rx receiver 162 and a Tx transmitter 163. One or more transceivers 160 are connected to one or more antennas 158. One or more memory units 155 include computer program code 153. RAN node 170 includes a scheduling module including one or both of the 150-1 and/or 150-2. These parts of the scheduling module may include processor configurations that may be implemented to carry out the embodiments of the invention disclosed herein, and may be implemented in several ways. The scheduling module may be implemented in hardware as a scheduling module 150-1, such as as part of one or more processors 152. The scheduling module 150-1 may also be implemented in an integrated circuit or in other hardware such as a field-programmable gate array. In another example, a scheduling module may be implemented as a scheduling module 150-2, which is implemented as computer program code 153 and executed by one or more processors 152. In addition, the scheduling modules shown in FIG. 7 are optional and their operations may be performed by other devices of RAN node 170 as shown in FIG. For example, one or more memory units 155 and computer program code 153 are configured to allow one or more processors 152 to cause RAN node 170 to perform one or more of the operations described herein. One or more network interfaces 161 communicate over the network, such as over links 176 and 131. Two or more RAN nodes 170 communicate using, for example, link 176. Link 176 may be wired, wireless, or both wired and wireless, and may implement, for example, an Xn interface for 5G, an X2 interface for LTE, or another suitable interface for other standards.

[0062] One or more buses 157 may be address, data, or control buses and may include any interconnection mechanism, such as a series of lines on a motherboard or integrated circuit, optical fiber or other optical communications equipment, wireless links, and the like. For example, one or more transceivers 160 may be implemented as a remote radio head (RRH) 195, with other elements of the RAN node 170 physically located in a different location than the RRH, and one or more buses 157 may be implemented partially in in the form of a fiber optic cable to connect other elements of the RAN 170 node to the RRH 195.

[0063] In other operations, the problem of unsuccessful detection of the transmission of a configured grant by the UE was considered. However, the proposed solution did not address the use of UL grants for the set of TTIs discussed in this document.

[0064] In one embodiment of the invention, a new method is provided for scheduling retransmissions for a burst of CG-PUSCH transmissions using UL grants for multiple TTIs. More specifically, at least a method and apparatus for:

1. indicating to the UE which of the CG-PUSCH transmissions in the CG-PUSCH resource packet of the UE should be retransmitted; and

2. determine the relationship between the UL grant for multiple TTIs and the CG-PUSCH transmission burst.

[0065] In addition, the method includes two options (Case 1 and Case 2 below) for specifying a HARQ process ID for HARQ processes that the UE should retransmit.

[0066] Case 1: The gNB gives the UE full freedom to choose the HARQ-ID in the CG-PUSCH packet. For retransmissions, when a UE receives a UL grant for a set of TTIs for a CG-PUSCH, it shall reinterpret the HARQ-IDs for the (re)transmitted CG-PUSCHs:

• Binding Method #1: The UL grant for multiple TTIs explicitly specifies the HARQ-ID of the first CG-PUSCH to be (re)transmitted and the number of PUSCHs (re)transmitted ("M"). The HARQ-IDs for a CG-PUSCH transmission other than the first are implicitly determined based on the first HARQ-ID and duration M in the UL grant for multiple TTIs;

• Binding Method #2: Alternatively, the HARQ-ID signaled by the gNB in the Multi-TTI Scheduling DCI may be reinterpreted as indicating the time of the first CG-PUSCH retransmitted, with the number of remaining retransmissions implicitly determined based on the first HARQ- The ID and duration of the UL grant of the set of TTIs.

[0067] Case 2: The gNB instructs (configures) the UE to sequentially select HARQ-IDs for CG transmission in the packet:

• Thus, the gNB can easily schedule retransmission using the UL grant for multiple TTIs.

[0068] The detailed operation of the UE according to the invention is described below:

- Step 1: receive from the gNB the CG PUSCH resource configuration and indicate the HARQ processes applicable for CG-PUSCH transmission (eg, HARQ processes 1 ... N _{HARQ_CG} );

- Step 2: Transmit N (at least one) of the CG-PUSCH transmissions in the resource burst configured for the CG-PUSCH and select a HARQ process ID for each such CG-PUSCH transmission:

- Assume that the HARQ identifiers for each CG-PUSCH transmission are designated as h ₁ , h ₂ , ... h _N , with the selected values not necessarily in any particular order;

- Step 3: Receive from the gNB a UL grant for multiple TTIs scheduling M PUSCH (re)transmissions, including:

- specifying the HARQ process ID and

- indication of the value of M indicating # of scheduled PUSCH transmissions:

- Note: both indications may be present in the UL grant for multiple TTIs;

- Step 4: determining whether bits such as UL Grant CRC bits for multiple TTIs are scrambled with C-RNTI or CS-RNTI (ie the RNTI used for CG transmissions);

- Step 5a: If the UL grant of the multiple TTIs is scrambled with the CS-RNTI (case 1 above):

- The UE shall include the CG-UCI in each scheduled (re)transmission,

- The UE transmits the first PUSCH within the scheduled M PUSCH transmissions using the HARQ process ID specified in step 3.

- Binding method #1: HARQ identifier (may be anything in the range h ₁ , h ₂ , ... h _N ) in the UL grant for a set of TTIs identifies the HARQ identifier of the first CG-PUSCH retransmission,

- Binding method #2: The UE reinterprets the HARQ process ID in the UL grant for the TTI set as a time offset relative to the first DCI slot of the TTI set, indicating the subframe, slot, slot half, or symbol of the first CG-PUSCH transmission in the UL CG packet for retransmission. For example, HARQ ID #0 in the UL multi-TTI grant may correspond to a CG-PUSCH that was transmitted in slot "x" that was two slots before the slot in which the UL multi-TTI grant was received (i.e., x=2 ), HARQ ID #1 corresponds to x=3, HARQ ID #2 corresponds to x=4, and so on. This may provide an alternative relationship between the DCI of a set of TTIs and the CG packet,

- HARQ identifiers for other M-1 TTIs are defined as follows:

- The next transmissions are transmissions that follow the transmission with the indicated HARQ ID (or the HARQ ID of the CG-PUSCH transmission pointed to by the reinterpreted HARQ ID field as described for linking method #2). This covers transmissions up to Pin- For transmissions beyond h _N , there are two alternatives:

- Alt1: if the grant for a set of TTIs specifies a number of HARQ processes M that is outside h _N , the UE may transmit data in these resources corresponding to other HARQ processes configured for CG transmissions,

- Alt2: M can serve as a DAI (Downlink Assignment Indicator) to ensure that the gNB does not miss (both UCI and PUSCH) any transmission from the UE within the packet. If the UE detects that M is different from the number of PUSCHs detected in the CG packet, it will ignore the NDI in the UL grant for the multiple TTIs and retransmit all the PUSCHs from the CG-PUSCH packet;

- Step 5b: If bits, such as UL grant CRC bits for multiple TTIs, are scrambled with C-RNTI:

- CG-UCI is not included in scheduled broadcasts,

- HARQ process numbering is sequential, starting at the specified HARQ-ID in the UL grant for a set of TTIs,

- As an embodiment of the invention, the gNB may indicate to the UE (eg, via RRC signaling) that the HARQ processes that the UE selects for CG transmissions should be sequential (case 2 above),

- As an embodiment of the invention, when a UL grant for a set of TTIs schedules a retransmission for a HARQ process that was transmitted by a CG-PUSCH, the HARQ processes pointed to by the UL grant for a set of TTIs are limited to a subset of the HARQ processes applicable for CG transmission -PUSH:

- for example, suppose 16 HARQ processes and HARQ processes 1-5 are allowed for CG-PUSCH, if the HARQ identifier specified in the UL grant for the set of TTIs is #3 and M=4 transmissions are scheduled, the UE shall transmit HARQ processes # 3, #4, #5 and #1.

[0069] It should be noted that in accordance with an embodiment of the invention, a process identification value, such as a HARQ identifier or a HARQ process identification, may be based on at least one bit field indicated to a network device by signaling, for example, without being limited to, uplink grant. In addition, the process identification value may explicitly indicate the HARQ process identifier for a particular data transmission, or may indicate, for example, a temporal reference to a previous data transmission. In addition, according to embodiments of the invention, the process ID value may be, for example, a HARQ process ID that the UE derives based on one or more process ID values.

[0070] Some examples in accordance with embodiments of the invention for determining transmitted HARQ processes are shown in FIG. 3.

[0071] FIG. 3 shows examples of how to determine transmitted HARQ process IDs. In FIG. 3 shows UE PUSCH transmission 310, gNB scheduling 320, and UE scheduled 330 transmission. As shown in FIG. 3, UE PUSCH transmission 310 and gNB scheduling 320 include four examples (A-D) of using and/or determining transmitted HARQ process identifiers according to embodiments of the invention. In all cases (A to D), it is assumed as a starting point that the UE transmitted four TVs in the CG-PUSCH consecutive resources corresponding to the HARQ IDs h1=1, h2=3, h3=4 and h4=6. These examples of using and/or defining transmitted HARQ process identifiers in accordance with embodiments of the invention include at least the following:

- Example A: gNB indicates by UL grant for multiple TTIs that the first retransmitted HARQ identifier is #1 and M=4 TB is to be transmitted. The HARQ processes for the remaining three TVs are the same as in the CG-PUSCH burst sent by the UE, ie #3, 4 and 6; The UE keeps track of the NDI indicator for each HARQ specified in the UL grant,

- Example B: The gNB may have missed (or misreceived) the TB for the HARQ #1 process, as well as the corresponding UCI) and decides to schedule M=3 TBs, the first one has HARQ ID #3. Accordingly, the UE transmits HARQ processes #3, 4 and 6;

- Example C: same as example B, but the gNB only schedules two HARQ processes, #3 and the next in sequence (#4); and

- Example D (corresponds to alternative Alt1 of step 5a): in this case, the gNB performs scheduling via UL grant for a set of TTIs for M=5 TB, the first of which corresponds to HARQ process #3. Since the UE's CG-PUSCH includes only 4 TBs (and 3 TBs from HARQ process ID #3 onwards), the UE will use the other two remaining PUSCH resources provided by the grant to transmit data corresponding to other CG-enabled HARQ processes on of your choice (in example D, these are #2 and #5).

[0072] FIG. 4 shows two examples E and F, where the UE cannot transmit one of the CG-PUSCHs in the CG-PUSCH transmission burst, for example, due to an unsuccessful LBT result. In addition, in FIG. 4 shows UE CG PUSCH transmission 410, gNB scheduling 420, and UE 430 scheduled transmission. These two examples include the case where the UE fails to transmit one of the CG-PUSCH (h3) in the CG-PUSCH transmission burst, leaving an empty gap between h2 and h4.

- Example E: The gNB schedules three CG-PUSCH resources for the UE with the first HARQ ID equal to #1. The UE transmits in the next two resources also PUSCH for the other two HARQ processes it used in this packet, i.e. #3 and #6,

- Example F (corresponds to Alt1 alternative in step 5a): gNB schedules by grant for a set of UL TTIs for M=3 TBs, the first of which corresponds to HARQ process #3. Since the UE has only transmitted 2 consecutive TVs (HARQ processes #1 and #3), the UE will use the remaining PUSCH resources provided by the grant to transmit data corresponding to another CG-enabled HARQ process of the UE's choice (in example F, this is #2) .

[0073] FIG. 5 shows examples G and H according to embodiments of the invention. Fig. 5 shows CG UE PUSCH transmission 510, gNB scheduling 520, and UE scheduled 530 transmission. In FIG. 5 shows an alternative implementation of the Alt2 step 5a as discussed above. As shown in FIG. 5, in example G, gNB indicates M=2, but the UE transmitted three TVs h1, h2 and h3 in UE CG PUSCH transmission packet 510.

[0074] It should be noted that it can be assumed that in FIG. 5 gNB misses UCI h2 (or h4):

- Example G and H (corresponds to Alt2 alternative of step 5a: UE transmits 3 TBs in CG-PUSCH packet. Received UL grant for multiple TTIs with CRC bits scrambled with CS-RNTI schedule two (M=2) transmissions :

- if the indicated HARQ ID has NDI switched (corresponding to a new transmission), the UE skips the transmission (here HARQ-ID #1) and retransmits the remaining PUSCHs corresponding to other HARQ-IDs (#3 and #6) as shown in example G. Otherwise, if retransmission is scheduled for HARQ process #1, the UE retransmits HARQ processes #1 and #3 as in the previous examples.

[0075] An advantage of the Alt2 alternative of step 5a is that the association between the NDI bits indicated in the DCI of multiple TTI scheduling and the corresponding HARQ process cannot become ambiguous. The disadvantage is that some processes may be retransmitted even if the gNB has already received them correctly, but this only happens if the gNB misses the CG-PUSCH UCI transmitted by the UE. UCI is supposed to be much more reliable than PUSCH.

[0076] FIG. 6 shows an embodiment of bonding method #2 in accordance with exemplary embodiments of the invention. In FIG. 6 shows UE PUSCH transmission 610, gNB scheduling 620, and UE scheduled transmission 630.

[0077] FIG. 6 shows that the gNB signaled multi-TTI UL grant uses a temporal offset (instead of the HARQ process ID) to identify the first PUSCH transmission in the (preceding) CG-PUSCH burst that the UE should retransmit. The temporal offset may be indicated by reusing the HARQ-ID field or by adding an additional DCI field to the UL grant for multiple TTIs. In this example, the offset is relative to the first configured transmission of the last CG packet. In other embodiments of the invention, the offset may be relative to the slot/symbol/half-slot in which the grant for the plurality of TTIs is received. Binding method 2 has the advantage that it allows the gNB to schedule retransmission for the Xth HARQ process sent in the CG-PUSCH packet in cases where the gNB can detect transmission from the UE (e.g., based on UE-specific DMRS detection) , but cannot decode the UCI including information about the HARQ process ID selected by the UE.

[0078] In each of FIGS. 8A and FIG. 8B shows a method in accordance with exemplary embodiments of the invention that can be performed with the device.

[0079] FIG. 8A illustrates operations that may be performed by a network device, such as, but not limited to, a network device such as UE 110 shown in FIG. 7. As shown at 810 in FIG. 8A, the method includes receiving, by a network device of a communication network, information containing an uplink grant for a plurality of transmission time slots with CRC bits scrambled with a radio network temporary identifier. As shown at 820 in FIG. 8A, the method includes determining, based on said information, by the network device a subset of data transmissions of a previous packet of data transmissions to be retransmitted by the network device. Then, as shown at step 830 in FIG. 8A, the method includes, based on said determination, a network device retransmitting a subset of data transmissions using the scheduled uplink grant resources.

[0080] In accordance with embodiments of the invention, as described in the paragraph above, a subset of data transmissions consists of at least one physical uplink shared channel transmission of a previous packet of data transmissions to be retransmitted.

[0081] In accordance with the embodiments of the invention, as described in the paragraphs above, the information containing the uplink grant contains at least one process identification value associated with a previous packet of data transmissions to be retransmitted, and the number of transmission time intervals, scheduled through the uplink grant.

[0082] According to the embodiments described in the paragraphs above, based on an uplink grant having CRC bits scrambled with a configured scheduling radio network temporary identifier, the network device includes configured grant uplink control information for each transmitting said subset of data, and retransmitting uses a scheduled uplink grant resource associated with a process identification value for each data transmission.

[0083] In accordance with the embodiments of the invention described in the paragraphs above, based on an uplink grant having CRC bits scrambled with a cell radio network temporary identifier, retransmission uses scheduled uplink grant resources associated with serial process ID values, starting with an initial process ID value indicated by at least one process ID value.

[0084] In accordance with the exemplary embodiments described in the paragraphs above, at least one uplink grant process identification value identifies one of the subframe, slot, or symbol of different packet transmission timeslots of a previously configured grant for retransmission.

[0085] In accordance with the embodiments described in the paragraphs above, at least one process identification value is a first process identification value indicating the first transmission of the retransmissions.

[0086] In accordance with the embodiments described in the paragraphs above, at least one process identification value indicates a temporal offset relative to the first slot of the uplink grant, wherein the temporal offset identifies the first subframe, slot, or symbol for the first transmission of the retransmission.

[0087] In accordance with the embodiments of the invention described in the paragraphs above, the process ID of at least one subsequent retransmission, different from the first transmission of a subset of data transmissions, is implicitly determined based on the first process ID of at least one process identification value and a duration in uplink grant.

[0088] In accordance with the embodiments of the invention, as described in the paragraphs above, each process identification scheduled with a grant is determined sequentially, starting with at least one process identification value, based on the uplink grant scrambled with a temporary identifier uplink radio network (RNTI dynamic grant).
