[0038] Turning to FIG. 1, this figure shows a block diagram of one possible and nonlimiting example in which the examples may be practiced. A user equipment (UE) 110, radio access network (RAN) node 170, and network element(s) 190 are illustrated. In the example of FIG. 1, the user equipment (UE) 110 is in wireless communication with a wireless network 100. A UE is a wireless device that can access the wireless network 100. The UE 110 includes one or more processors 120, one or more memories 125, and one or more transceivers 130 interconnected through one or more buses 127. Each of the one or more transceivers 130 includes a receiver, Rx, 132 and a transmitter, Tx, 133. The one or more buses 127 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, fiber optics or other optical communication equipment, and the like. The one or more transceivers 130 are connected to one or more antennas 128. The one or more memories 125 include computer program code 123. The UE 110 includes a module 140, comprising one of or both parts 140-1 and / or 140-2, which may be implemented in a number of ways. The module 140 may be implemented in hardware as module 140-1, such as being implemented as part of the one or more processors120. The module 140-1 may be implemented also as an integrated circuit or through other hardware such as a programmable gate array. In another example, the module 140 may be implemented as module 140-2, which is implemented as computer program code 123 and is executed by the one or more processors 120. For instance, the one or more memories 125 and the computer program code 123 may be configured to, with the one or more processors 120, cause the user equipment 110 to perform one or more of the operations as described herein. The UE 110 communicates with RAN node 170 via a wireless link 111.

[0039] The RAN node 170 in this example is a base station that provides access for wireless devices such as the UE 110 to the wireless network 100. The RAN node 170 may be, for example, a base station for 5G, also called New Radio (NR). In 5G, the RAN node 170 may be a NG-RAN node, which is defined as either a gNB or an ng-eNB. A gNB is a node providing NR user plane and control plane protocol terminations towards the UE, and connected via the NG interface (such as connection 131) to a 5GC (such as, for example, the network element(s) 190). The ng-eNB is a node providing E-UTRA user plane and control plane protocol terminations towards the UE, and connected via the NG interface (such as connection 131) to the 5GC. The NG-RAN node may include multiple gNBs, which may also include a central unit (CU) (gNB-CU) 196 and distributed unit(s) (DUs) (gNB-DUs), of which DU 195 is shown. Note that the DU 195 may include or be coupled to and control a radio unit (RU). The gNB-CU 196 is a logical node hosting radio resource control (RRC), SDAP and PDCP protocols of the gNB or RRC and PDCP protocols of the en-gNB that control the operation of one or more gNB-DUs. The gNB-CU 196 terminates the Fl interface connected with the gNB-DU 195. The Fl interface is illustrated as reference 198, although reference 198 also illustrates a link between remote elements of the RAN node 170 and centralized elements of the RAN node 170, such as between the gNB-CU 196 and the gNB-DU 195. The gNB-DU 195 is a logical node hosting RLC, MAC and PHY layers of the gNB or en-gNB, and its operation is partly controlled by gNB-CU 196. One gNB-CU 196 supports one or multiple cells. One cell may be supported with one gNB-DU 195, or one cell may be supported / shared with multiple DUs under RAN sharing. The gNB-DU 195 terminates the Fl interface 198 connected with the gNB-CU 196. Note that the DU 195 is considered to include the transceiver 160, e.g., as part of a RU, but some examples of this may have the transceiver 160 as part of a separate RU, e.g., under control of and connected to the DU 195. The RAN node 170 may also be an eNB (evolved NodeB) base station, for LTE (long term evolution), or any other suitable base station or node.

[0040] The RAN node 170 includes one or more processors 152, one or more memories 155, one or more network interfaces (N / W I / F(s)) 161, and one or more transceivers 160 interconnected through one or more buses 157. Each of the one or more transceivers 160 includes a receiver, Rx, 162 and a transmitter, Tx, 163. The one or more transceivers 160 are connected to one or more antennas 158. The one or more memories 155 include computer program code 153. The CU 196 may include the processor(s) 152, one or more memories 155, and network interfaces 161. Note that the DU 195 may also contain its own memory / memories and processor(s), and / or other hardware, but these are not shown.

[0041] The RAN node 170 includes a module 150, comprising one of or both parts 150-1 and / or 150-2, which may be implemented in a number of ways. The module 150 may be implemented in hardware as module 150-1, such as being implemented as part of the one or more processors 152. The module 150-1 may be implemented also as an integrated circuit or through other hardware such as a programmable gate array. In another example, the module 150 may be implemented as module 150-2, which is implemented as computer program code 153 and is executed by the one or more processors 152. For instance, the one or more memories 155 and the computer program code 153 are configured to, with the one or more processors 152, cause the RAN node 170 to perform one or more of the operations as described herein. Note that the functionality of the module 150 may be distributed, such as being distributed between the DU 195 and the CU 196, or be implemented solely in the DU 195.

[0042] The one or more network interfaces 161 communicate over a network such as via the links 176 and 131. Two or more gNBs 170 may communicate using, e.g., link 176. The link 176 may be wired or wireless or both and may implement, for example, an Xn interface for 5G, an X2 interface for LTE, or other suitable interface for other standards.

[0043] The 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, fiber optics or other optical communication equipment, wireless channels, and the like. For example, the one or more transceivers 160 may be implemented as a remote radio head (RRH) 195 for LTE or a distributed unit (DU) 195 for gNB implementation for 5G, with the other elements of the RAN node 170 possibly being physically in a different location from the RRH / DU 195, and the one or more buses 157 could be implemented in part as, for example, fiber optic cable or other suitable network connection to connect the other elements(e.g., a central unit (CU), gNB-CU 196) of the RAN node 170 to the RRH / DU 195. Reference 198 also indicates those suitable network link(s).

[0044] A RAN node / gNB can comprise one or more TRPs to which the methods described herein may be applied. FIG. 1 shows that the RAN node 170 comprises TRP 51 and TRP 52, in addition to the TRP represented by transceiver 160. Similar to transceiver 160, TRP 51 and TRP 52 may each include a transmitter and a receiver. The RAN node 170 may host or comprise other TRPs not shown in FIG. 1.

[0045] A relay node in NR is called an integrated access and backhaul node. A mobile termination part of the IAB node facilitates the backhaul (parent link) connection. In other words, the mobile termination part comprises the functionality which carries UE functionalities. The distributed unit part of the IAB node facilitates the so called access link (child link) connections (i.e. for access link UEs, and backhaul for other IAB nodes, in the case of multi-hop IAB). In other words, the distributed unit part is responsible for certain base station functionalities. The IAB scenario may follow the so called split architecture, where the central unit hosts the higher layer protocols to the UE and terminates the control plane and user plane interfaces to the 5G core network.

[0046] It is noted that the description herein indicates that “cells” perform functions, but it should be clear that equipment which forms the cell may perform the functions. The cell makes up part of a base station. That is, there can be multiple cells per base station. For example, there could be three cells for a single carrier frequency and associated bandwidth, each cell covering one-third of a 360 degree area so that the single base station’s coverage area covers an approximate oval or circle. Furthermore, each cell can correspond to a single carrier and a base station may use multiple carriers. So if there are three 120 degree cells per carrier and two carriers, then the base station has a total of 6 cells.

[0047] The wireless network 100 may include a network element or elements 190 that may include core network functionality, and which provides connectivity via a link or links 181 with a further network, such as a telephone network and / or a data communications network (e.g., the Internet). Such core network functionality for 5G may include location management functions (LMF(s)) and / or access and mobility management function(s) (AMF(S)) and / or user plane functions (UPF(s)) and / or session management function(s) (SMF(s)). Such core network functionality for LTE may include MME (mobility management entity) / SGW(serving gateway) functionality. Such core network functionality may include SON (self-organizing / optimizing network) functionality. These are merely example functions that may be supported by the network element(s) 190, and note that both 5G and LTE functions might be supported. The RAN node 170 is coupled via a link 131 to the network element 190. The link 131 may be implemented as, e.g., an NG interface for 5G, or an SI interface for LTE, or other suitable interface for other standards. The network element 190 includes one or more processors 175, one or more memories 171, and one or more network interfaces (N / W I / F(s)) 180, interconnected through one or more buses 185. The one or more memories 171 include computer program code 173. Computer program code 173 may include SON and / or MRO functionality 172.

[0048] The wireless network 100 may implement network virtualization, which is the process of combining hardware and software network resources and network functionality into a single, software-based administrative entity, or a virtual network. Network virtualization involves platform virtualization, often combined with resource virtualization. Network virtualization is categorized as either external, combining many networks, or parts of networks, into a virtual unit, or internal, providing network-like functionality to software containers on a single system. Note that the virtualized entities that result from the network virtualization are still implemented, at some level, using hardware such as processors 152 or 175 and memories 155 and 171, and also such virtualized entities create technical effects.

[0049] The computer readable memories 125, 155, and 171 may be of any type suitable to the local technical environment and may be implemented using any suitable data storage technology, such as semiconductor based memory devices, flash memory, magnetic memory devices and systems, optical memory devices and systems, non-transitory memory, transitory memory, fixed memory and removable memory. The computer readable memories 125, 155, and 171 may be means for performing storage functions. The processors 120, 152, and 175 may be of any type suitable to the local technical environment, and may include one or more of general purpose computers, special purpose computers, microprocessors, digital signal processors (DSPs) and processors based on a multi-core processor architecture, as nonlimiting examples. The processors 120, 152, and 175 may be means for performing functions, such as controlling the LTE 110, RAN node 170, network element(s) 190, and other functions as described herein.

[0050] In general, the various example embodiments of the user equipment 110 can include,but are not limited to, cellular telephones such as smart phones, tablets, personal digital assistants (PDAs) having wireless communication capabilities, portable computers having wireless communication capabilities, image capture devices such as digital cameras having wireless communication capabilities, gaming devices having wireless communication capabilities, music storage and playback devices having wireless communication capabilities, internet appliances including those permitting wireless internet access and browsing, tablets with wireless communication capabilities, head mounted displays such as those that implement virtual / augmented / mixed reality, as well as portable units or terminals that incorporate combinations of such functions. The UE 110 can also be a vehicle such as a car, or a UE mounted in a vehicle, a UAV such as e.g. a drone, or a UE mounted in a UAV. The user equipment 110 may be a terminal device, such as mobile phone, mobile device, sensor device etc., the terminal device being a device used by the user or not used by the user.

[0051] UE 110, RAN node 170, and / or network element(s) 190, (and associated memories, computer program code and modules) may be configured to implement (e.g. in part) the methods described herein. Thus, computer program code 123, module 140-1, module 140-2, and other elements / features shown in FIG. 1 of UE 110 may implement user equipment related aspects of the examples described herein. Similarly, computer program code 153, module 150-1, module 150-2, and other elements / features shown in FIG. 1 of RAN node 170 may implement gNB / TRP related aspects of the examples described herein. Computer program code 173 and other elements / features shown in FIG. 1 of network element(s) 190 may be configured to implement network element related aspects of the examples described herein.

[0052] Having thus introduced a suitable but non-limiting technical context for the practice of the example embodiments, the example embodiments are now described with greater specificity.

[0053] Repetitions are useful in a variety of cases e.g.: power limited UE, e.g. avoiding segmenting overhead (PUSCH), POLITE to decrease the peak interference among cells. (PDSCH), reduce PDCCH loading (PUSCH and PDSCH), higher latency links (e.g. Non terrestrial networks), and / or (PUSCH and PDSCH), and lower latency services (e.g. URLLC) (PUSCH and PDSCH).

[0054] With the current standard it is already possible to explicitly, dynamically adapt thenumber of repetitions with each DCI / dynamic grant, i.e. changing the number of repetitions on a per HARQ attempt basis.

[0055] However, even with this existing approach, the number of repetitions needs to be selected at the time the DCI grant is transmitted. As a result, especially with larger numbers of repetitions (e.g. with URLLC), or larger K (e.g. K2) values, and / or CG, the number of repetitions needs to be selected without the benefit of additional information which may become available after the scheduling DCI is sent, but prior to the last repetition. As a result, the number of repetitions selected may be larger or smaller than actually needed, e.g. when the RF channel conditions change after the DCI is sent / the HARQ attempt is scheduled.

[0056] Transmitting more repetitions than needed can waste energy, e.g. on the uplink can waste UE battery life, and on the downlink may waste network energy. However, without the proposed ability to refine the number of reps more dynamic way, the NW will not need to be as conservative when trying to hit a specific delay budget as in the event of degrading RF it can automatically get the benefit of extra repetitions. And in improving RF conditions, it can avoid the need to send extra repetitions.

[0057] Avoiding extra DCI signaling is a quite important benefit. Extra DCI signaling may for example require the UE to use excess power and excess resources.

[0058] Transmitting repetitions in general can generate excess interference, and can displace the PRBs for other UEs and services.

[0059] Repetitions are more likely to be used in cases where there is an elevated need to conserve energy. For example, cell edge UEs consume significantly higher Tx power bit where transmitting to gNB where there is additional fading etc. NTN links are also more energy constrained at both the UE (increased UE Tx power) and at the gNB (as it is a Satellite). URLLC and other high-priority applications can also be more sensitive to energy consumption at both the UE (increased UE Tx power) and at the gNB e.g. as the service may be for public safety, and be expected to work even during power outages.

[0060] Early Termination: Explicit signaling (where the NW can signal to explicitly terminate UE transmission of PUSCH repetitions early, for use in the case where the NW successfully decodes the PUSCH Tx after receiving a subset of the PUSCH repetitions) is a possible implementation, such as for multi-TB early termination for LTE-MTC. In this case,there are no DCI savings due to use of explicit ACK - as there may be a need to transmit a DCI to ACK a subset of the TBs. With an implicit ACK, there is flexibility on scheduling (e.g. it is possible to transition to a different narrowband, change number of repetitions, etc.). No explicit signaling is needed to implement the example embodiments described herein.

[0061] A UE Constrained Blind Decode Configuration for UE ES where NW constrains PDCCH AL Power may be implemented, related to using a NW defined configuration that contains rules for dynamically switching Aggregation Levels for reducing PDCCH blind decode attempts. In the approach related to the NW dynamically switching aggregation levels, the NW configuration rules do not set defined rules or set thresholds to control PUSCH and / or PDSCH repetitions.

[0062] A swift HARQ based on Machine Learning for latency minimization in URLLC may be implemented, where machine learning is employed to reduce HARQ latency by a Swift HARQ procedure. Swift HARQ couples the NACK message with an estimation concerning the number of retransmission rounds required to successfully decode the packet. Based on this feedback, the transmitter reacts early by dropping the non-decodable packet or enters a repetition mode in which the codewords continuously retransmit. The receiver, meanwhile, stops releasing the NACK message until the codeword is successfully decoded. The example embodiments described herein relate to defining a configuration containing a set of rules and thresholds to either increase or decrease repetitions in PUSCH or PDSCH dynamically. Further, the examples described herein do not rely on machine learning based techniques.

[0063] It is possible to enable and use an early Hybrid Automatic Repeat reQuest (HARQ) feedback for reducing the latency of acknowledged transmissions without disregarding spectral efficiency. As an enabler of such early feedback, this relates to a technique for predicting the decoder outcome before decoding occurs. The examples described herein relate to a configuration containing a set of rules and thresholds to either increase or decrease repetitions in PUSCH or PDSCH dynamically.

[0064] The examples described herein relate to dynamically and implicitly scaling the (number of) PUSCH and / or PDSCH repetitions based on history information of successful HARQ decodes and / or CQI / AL history.

[0065] The technical problem solved by the methods described herein is how to leverage more recent information about the channel, i.e. after the scheduling DCI, so that the UE canavoid sending excess repetitions, while still sending the additional repetitions when they are more likely needed and without requiring any additional signaling overhead. As such, the problem is to improve upon the existing approach where the number of repetitions needs to be selected at the time the DCI grant is transmitted so that the number of repetitions selected can benefit from additional information which may become available after the DCI is sent, but prior to the last repetition. This is especially important with larger numbers of repetitions, and larger K (e.g. K2) values. In this context, larger K values means a larger time offset from the DCI grant to the first transmission (on the UL, for example a larger K2 value). Transmitting more repetitions than needed can waste energy, e.g. on the uplink can waste UE battery life, and on the downlink may waste network energy. Transmitting repetitions in general can generate excess interference.

[0066] The problem is therefore how to, without requiring additional signaling overhead during the HARQ process, better avoid (UE) sending excess repetitions when they are less likely needed: in the uplink this can save UE battery life and avoid interference, and in the downlink this can avoid interference and save NW energy.

[0067] At a high level, described herein is a method (which may be relevant to standardization) where the NW configures UE with rules such that the UE implicitly limits / adapts which repetitions it transmits (or receives) based upon certain triggering information where that triggering information is known both the UE and NW.

[0068] This new NW configuration is sent to the UE over RRC, where DCI, or MAC CE etc. may further configure e.g. the thresholds / percentage / parameters such that: the NW and UE implicitly adapt the number of HARQ repetitions based on information received after the repetitions are scheduled (e.g. after the DCI for the dynamic grant); implicit adaptation is based on the jointly known recent history of AL / CSI, and recent history of HARQ retransmissions, i.e. which are jointly known at the transmitter and receiver; thresholds for that implicit switching (stretching / shortening or alternatively increasing / reducing the number of repetitions on PUSCH / PDSCH) are part of the (semi-static) RRC configuration.

[0069] For example: UE and NW implicitly terminate repetitions early (e.g. after 50% or 75% of the repetitions) if UE detects one or more of the following aspects are (or are changed) greater than or less than some threshold: CSI measurements, or AL of the recent history (last) DCI subsequent to the NW deciding on the number of reps indicated in the HARQ processDCI which is now being dynamically refined that the UE(s) decoded, or number of HARQ retransmissions (bundles) prior to HARQ successful decode on the other prior HARQ process, or number of HARQ retry reps on other HARQ process prior to successful decoding, or an extra explicit indicator appended to subsequent DCI for another HARQ process. The extra explicit indicator appended to subsequent DCI for another HARQ process would be optional, as it is preferred to avoid any new explicit signaling, but this could be included as a dependent claim. This explicit indication would add a couple bits to the DCI similar to what was done to append the PDCCH skipping and / or SSSG switching indication to another DCI in Rell7.

[0070] A subsequent DCI on another HARQ process has a number of repetitions and MCS choice for the repetitions. On a particular HARQ process the number of repetitions that have been indicated in DCI can be adapted according to a subsequent DCI on another HARQ process that may have a different number of repetitions and / or MCS.

[0071] The rules and aspects are known by both the UE and NW and can be used to estimate the SINR.

[0072] In other words: the network and the UE exchange a set of rules to limit / adapt which repetitions the UE or NW transmits (or receives), and at cell edge conditions the network and UE rely on a history of successfully decoded DCI and their corresponding AL, prevailing RF conditions determined via CSI measurements, and a history of number of HARQ attempts and / or repetitions on the same HARQ process and other active HARQ process ids (prior to HARQ successful decode on the prior HARQ process).

[0073] As a high-level illustration of dynamic PUSCH repetition scaling, FIG. 2 and FIG.3 show the UE decisions to scale repetitions based on Policy Rules. FIG. 2 shows a scenario where n8 repetitions (in other words, 8 repetitions) have been configured by the NW (at 202), and the UE 110 after a set of 2 PUSCH repetitions (namely PUSCH repetition 204 and PUSCH repetition 206) comes to a decision to scale the number of PUSCH repetitions to 4 (n4), including PUSCH repetition 208 and PUSCH repetition 210. The NW is synchronized to the UE decision because of a common shared set of policy rules to scale repetitions. Thus FIG. 2 is an illustration of UE 110 deciding to have less PUSCH repetitions based on configured policy rules.

[0074] FIG. 3 shows a scenario where nl repetition (in other words, 1 repetition) has been configured by the NW (at 302), and the UE 110 after 1 PUSCH repetition 304 comes to adecision to scale the number of PUSCH repetitions to 4 (n4), including performing PUSCH repetition 306, PUSCH repetition 308, and PUSCH repetition 310. The NW is synchronized to the UE decision because of a common shared set of policy rules to scale repetitions. FIG.3 is thus an illustration of UE 110 and the NW (e.g. RAN node 170) deciding to have more PUSCH repetitions based on configured policy rules.

[0075] The dynamic re-scaling of repetitions, mid-way through the repetitions, can be applied to both UL (PUSCH) and DL (PDSCH) repetitions. The principle of scaling PDSCH and PUSCH repetitions are both based on a common NW and UE policy and / or NW and UE information exchange.

[0076] Examples of policy for dynamically scaling HARQ repetitions (the examples below (1-5) are to be considered per HARQ process ID):

[0077] 1) Shrinking: Rep 8 DCI granted, but UE uses IR rule to only use Rep 4.

[0078] 2) Expanding: Rep 1 DCI granted, but UE uses IR rule to only use Rep X, X>1.

[0079] 3) Based on CQI Measurements history: If CQI measurements made at UE and reported to network is 6dB beyond the average wideband CQI measurements or average sub band CQI measurements over an allocated sub band, then the HARQ repetitions expand / scaled to a higher value.

[0080] 4. Based on DCI decoding and / or AL history: HARQ repetition on HARQ Id#n scales to a higher value (increases 2x from 4 to 8 repetitions) if either or both of i or ii: i. UE detects (in slot 4) more recent PDCCH DCIs on Id#n with lower AL (e.g. AL2 on HARQ ID#m) where the DCI for HARQ process #n (in slot 0) used the much higher AL8, 1. Where this implies the prior history of good channel conditions, is now trending toward much worse RF conditions, and NW uses this to additionally cause the UE to send the higher value of repetitions, and / or ii. UE detects (in slot 4) more recent PDCCH DCIs on Id#n for a larger number of repetitions (e.g. AL2 on HARQ ID#m) where the DCI for HARQ process #n (in slot 0) used the much higher AL8, 1. Where this implies the prior history of good channel conditions, is now trending toward much worse RF conditions, and NW uses this to additionally cause the UE to send the higher value of repetitions, iii. If more recent DCIs (Id#n) successfully decoded with lower AL (e.g. AL2 on HARQ ID#m, which is much lower than the AL8 on HARQ process #n, implying a history of good channel conditions, which isnow trending toward worse RF conditions), iv. If the current AL is higher (e.g. AL8).

[0081] 5) Based on history of HARQ repetitions for other active HARQ process ids, e.g. if HARQ repetition 8 was signaled, but then the UE received DCI for another HARQ process indicating no repetitions, then the 8 HARQ repetitions scales to a lower value.

[0082] Repetition may only be scaled (or skipped) after the triggering condition (as above) is known by both the UE and NW.

[0083] A sequence example timeline is summarized (for PUSCH repetition scaling) as follows (which example timeline is also shown in FIG. 4) with 2 HARQ process IDs (Id#n and Id#m, where m < n). Detailed logic flow and explanation is included herein. The same framework applies to PDSCH repetition scaling.

[0084] An example PUSCH repetition scaling timeline in FDD mode of operation is as follows:<

[0085] The option / range for repetition scaling can be configured as an attribute of theTDRA table.

[0086] TDRA Background: The uplink TDRA lookup tables Table 6.1.2.1.1-2, and Table 6.1.2.1.1-3 in 3GPP TS 38.214 include time domain resource allocation for multiple HARQ repetitions. In a DL DCI grant the network allocates TD resources for PUSCH transmissions corresponding to Transport Blocks following a TDRA pattern selected from the TDRA lookup table(s), in case of multiple PUSCH grants. DCI indicates the row number in the table.

[0087] In the FDD example, the TDRA (TimeDomainResourceAllocation) table, could be configured as follows:TDRA (timedomainresourceallocation) tableo Row 1 = Rep 1, K2=2, MCS XYZ, ..o Row 2 = Rep 2-6 , K2=2, MCS XYZ,o ...o Row 11 = Rep 4-4, K2=2, MCS XYZ,o Row 12 = Rep 8, K2=2, MCS XYZ,o Row 13 = Rep 4-8, K2=2, MCS XYZ,o ..Slot 0 send the DCI indicating an index into the TDRA table (example: TDRA table index points to Row 13 where Rep = 4-8, K2=2, MCS = XYZ)o NW looks up the PUSCH repetition configuration in this table and sees that the row in TDRA table that matches the configuration is - Row 13 o NW sends the value 13 in the DCI to the UE.

[0088] The HARQ process with its repetitions being refined (e.g. HARQ Id#n in section 6) could be either a dynamic grant, or a configured grant.

[0089] The examples described herein provide for a 3 GPP standards change where a configuration is introduced into the PUSCH-Config, and / or PDSCH-Config for dynamic rescaling of PUSCH repetitions.

[0090] The following Table 1 (also shown in FIG. 5) gives details of an example RRC configuration for PUSCH / PDSCH Repetition scaling. Table 1 consists of thresholds and rules that the UE and NW need to consider increasing or decreasing the repetition count of PUSCHand PDSCH repetitions respectively.

[0091] The configuration structure PXSCH-AggregationScalingThresholds-r20 (item 502) in Table 1 is used to set the rules and thresholds for dynamic scaling of PUSCH and PDSCH repetitions. This structure will be instantiated from the PUSCH-Config and PDSCH-Config and shall be initialized for UL and DL configurations respectively.Table 1<><><>

[0092] Table 1 thus shows an RRC configuration for dynamic scaling of PUSCH and PDSCH repetitions.

[0093] The TDRA tables for PUSCH (refer to Section 1 UL (PUSCH) Repetitions as follows) and PDSCH (refer to Section 2 DL (PDSCH) Repetitions as follows) resource allocation will also introduce additional entries to define repetition scaling factors in the event of the minimum thresholds defined in the above configuration are exceeded.

[0094] 1. UL (PUSCH) Repetitions

[0095] Additional TDRA table entries may be a configurable via RRC signaling. Each additional entry will define a Row index, a mapping type, a slot offset K2, a starting symbol S and an allocation length L.

[0096] The mapping may be used for either type A, or type B for the scheduled PUSCH transmission. Slot offset K2 provides the offset relative to DCI reception slot. Starting symbol specifies the symbol of the slot at which PUSCH transmission starts. The allocation length L defines a symbol length from the start symbol S. S and L can be indicated by a single SLIV indicator.

[0097] TDRA field of the DCI indicates one of the rows of the TDRA table. For example, if there are 16 entries in the TDRA table 4 bits are needed to cover the entire table in the DCI’s TDRA indicator field.

[0098] The scope of this IR is applicable to Resource Allocation in Time domain that considers UE specific PUSCH repetition scheduling. Below is the section from 3GPP TS 38.214 that specifies the PUSCH TDRA to be applied in scope of this IR.

[0099] 3GPP TS 38.214 mentions the following about PUSCH repetitions configured via pusch-AggregationFactor and the numberOfRepetitions.

[0100] The flow diagram in FIG. 6 shows the UE side handling of dynamically re-scaled PUSCH repetitions. The rules and thresholds exchanged between NW and UE at RRC configuration serve as a guidance for the UE to dynamically adjust its PUSCH repetitions. The NW will be synchronized to the UE implicitly when the repetitions are scaled up or scaled down as the same set of rules are evaluated on both sides of the radio interface for L1 / L2 scheduling. FIG. 6 thus shows the logic flow of dynamic PUSCH repetition scaling (per HARQ process) at the UE side.

[0101] UE Processing of Dynamic PUSCH repetition (per HARQ process) scaling (see FIG.6)

[0102] Step 1: UE Receives RRC Reconfiguration with PUSCH-config information containing, (Novel) Skip repetition configuration consisting of a repetition scaling factor. (Novel) Thresholds to check for scaling repetition count.

[0103] Step 2: UE decodes PUSCH grant from PDCCH DCI. DCI_format_0_l / DCI_format_0_2 will contain the Time domain resource assignment which carries the row index of the (Novel) PUSCH-TimeDomainResourceAllocationList-r20 configuration.

[0104] Described herein are example embodiments where the UE receives rules and / or policies for scaling PUSCH repetitions and the repetition scaling factor and thresholds that are part of the Rules / Policies are configured in the TDRA configuration contained in PUSCH-TimeDomainResourceAllocationList-r20.

[0105] Step 3: Following the PUSCH grant for HARQ Id#n, the UE transmits PUSCH repetitions according to TDRA index in DCI.

[0106] Step 4: Policy Rules in the TDRA configuration allow the UE to scale the PUSCH repetitions to a configured level.

[0107] Step 5: UE checks the Rules / conditions and thresholds during the transmission of repetitions and / or at the time of processing the new PUSCH grants for HARQ Id#n. UE determines if a particular Rule / condition or a combination of conditions are met for scaling the original repetition factor configured.

[0108] Step 6: If any one, or a combination of the configured conditions are met, the UE decides to scale the PUSCH repetitions by the amount configured in pusch-RepetitionScalingFactor.

[0109] If conditions are not met, then UE continues its PUSCH repetitions according to Step 3 or follows the number of PUSCH repetitions as configured in numberOfRepetitions.

[0110] In one example (with reference to Table 1 of FIG. 5 and Table 2 of FIG. 9, and the message sequence flow of FIG. 8A and FIG. 8B), if the pusch-AggregationF actor was set to n4, and the TDRA index indicated in DCI pointed to a configuration with pusch-RepetitionScalingF actor set to n2, if the conditions / thresholds in pusch-AggregationScalingThresholds-r20 contained in PUSCH-Config are met, the UE will set the number of PUSCH repetition counts to n2. This means that the PUSCH repetitions are reduced as per Policy rules / conditions.[OHl] The flow diagram in FIG. 7 shows the NW side handling of dynamically scaled PUSCH repetitions. In particular, FIG. 7 shows a logic flow of dynamic PUSCH repetition ( for each HARQ process) scaling at the NW side.

[0112] NW Processing of Dynamic PUSCH repetition (per HARQ Process) scaling (see FIG. 7)

[0113] Step 1: NW sends RRC Reconfiguration with PUSCH-config information containing, Skip repetition configuration consisting of a repetition scaling factor. Thresholds to check for scaling repetition count. PUSCH-TimeDomainResourceAllocationList-r20 configuration

[0114] Step 2: NW transmits PUSCH grant on PDCCH DCI. DCI_format_0_l / DCI_format_0_2 will contain the time domain resource assignment which carries the row index of the PUSCH allocation table.

[0115] Described herein are example embodiments where the network sets rules and / or policies for scaling PUSCH repetitions and the repetition scaling factor and thresholds that are part of the Rules / Policies are configured in the TDRA configuration contained in PUSCH-TimeDomainResourceAllocationList-r20.

[0116] Step 3 : Following the PUSCH grant, the NW receives PUSCH repetitions on HARQ Id#n with count according to TDRA index in DCI.

[0117] Step 4: Policy Rules in the TDRA configuration allow the UE to scale the PUSCH repetitions for HARQ Id#n to a configured level. These rules are known at both NW and UE.

[0118] NW evaluates the Rules / conditions and thresholds during the transmission of repetitions and / or at the time of processing the new PUSCH grants. UE determines if a particular Rule / condition or a combination of conditions are met for scaling the original repetition factor configured.

[0119] Step 6: If any one, or combination of the configured conditions are met, the NW expects the UE to scale the PUSCH repetitions by the amount configured in pusch-RepetitionScalingFactor.

[0120] If conditions are not met, then NW expects the UE to continue its PUSCH repetitions according to Step 3 or expects that the UE follows the number of PUSCH repetitions as configured in pusch-AggregationF actor / numberOfRepetitions.

[0121] In one example (with reference to Table 1 of FIG. 5 and Table 2 of FIG. 9, and the message signaling flow of FIG. 8A and FIG. 8B), DCI pointed to a configuration with numberOfRepetitions = n4. In the Policy Rules for Dynamic Repetition scaling, pusch-RepetitionScalingF actor is set to n2. The conditions / thresholds in pusch-AggregationScalingThresholds-r20 contained in PUSCH-Config are met, and the repetition scaling factor is 2x. Out of the 4 remaining repetitions that the UE is set to transmit, it will scale the number of repetitions by 2, and hence it will transmit only 2 out of the remaining 4. This means that the PUSCH repetitions are reduced as per Policy rules / conditions.

[0122] The message signaling flow diagram of FIG. 8A and FIG. 8B shows dynamic PUSCH repetition scaling per HARQ process Id after an evaluation of conditions / Policy Rules jointly by the UE and NW. No explicit signaling to scale repetitions is needed. In particular, FIG. 8A and FIG. 8B show a message Sequence flow for UE and NW side procedure for PUSCH repetition (for each HARQ process) scaling.

[0123] The following is an explanation of the message sequence flow shown in FIG. 8A and FIG. 8B between the UE side and the and NW side for PUSCH repetition scaling which is applicable to each active HARQ process:

[0124] The UE 110 and gNB 170 (the NW) are in an RRC CONNECTED mode or state.

[0125] Step 1 : UE capability information is transmitted from UE 110 to NW 170 to indicate its support of PUSCH repetition scaling, in an example by the UE 110 indicating to NW 170 ‘(pusch-RepetitionScaling: supported)’ as shown in FIG. 8A.

[0126] Step 2: gNB 170 determines UE’s PUSCH repetition Type A / B capability.

[0127] Step 3: RRC Reconfiguration from NW to UE to configure Rel-20 TDRA tables with additional rows having PUSCH repetition scaling factors, Beta Offsets, and Policy Rules and / or their combinations to enable evaluation of scaling of PUSCH repetitions. In particular, the gNB 170 transmits to the UE 110 an RRC reconfiguration (with Rel-20 TDRA tables, conditions, thresholds and timers for dynamic repetition scaling).

[0128] Steps 4-12: UL (and DL) data transfer between UE and NW, and PUSCH repetitions being transmitted from UE as in legacy procedures because the scaling of PUSCH repetitions on the UE side are not yet evaluated to be necessary.

[0129] Step 4: the UE 110 and gNB 170 perform data transfer (URLLC / eMBB).

[0130] Step 5: the gNB 170 determines that SINR conditions are met to enable PUSCH repetition.

[0131] Step 6: the UE 110 and gNB 170 perform activation of PUSCH repetition.

[0132] Step 7: the gNB 170 selects a PUSCH repetition and TDRA index.

[0133] Step 8: the gNB 170 transmits to UE 110 a PDCCH (DCI_0_l / DCI_0_2) R-16TDRA index with pusch-AggregationF actor = 4, and BetaOffsets.

[0134] Step 9: UE 110 transmits to the gNB 170 PUSCH repetition 1.

[0135] Step 10: UE 110 transmits to the gNB 170 PUSCH repetition 2.

[0136] Step 11 : UE 110 transmits to the gNB 170 PUSCH repetition 3.

[0137] Step 12: UE 110 transmits to the gNB 170 PUSCH repetition 4.

[0138] Steps 13-17: Evaluation of Policy Rules defined by NW for repetition scaling and configured to the UE in Step 2, yield a decision on UE (and NW) to move to a scaled PUSCH repetition mode. In this example it is a reduction in PUSCH repetition from n4 to n2.

[0139] Step 13: gNB 170 and UE 110 performs evaluation of one or more policy rules for dynamic repetition scaling.

[0140] Step 14: UE 110 decides scaling of PUSCH repetition to 2x, and looks up a TDRA Rel-20 configuration matching the repetition number for the evaluated condition, and gNB 170 decides scaling of PUSCH repetition to 2x, and looks up a TDRA Rel-20 configuration matching the repetition number for the evaluated condition.

[0141] Step 15: UE 110 prepares for dynamic scaling of PUSCH repetition Tx and optionally starts a configured timer for repetition scaling, and gNB 170 prepares for dynamic scaling of PUSCH repetition Tx and optionally starts a configured timer for repetition scaling.

[0142] Step 16: UE 110 transmits PUSCH repetition 1 to gNB 170.

[0143] Step 17: UE 110 transmits PUSCH repetition 2 to gNB 170.

[0144] Further, Table 2 below (Table 2 is also depicted in FIG. 9) shows proposed changes to the PUSCH-Config structure for enabling dynamic PUSCH repetition scaling.

[0145] Structure elements of PUSCH-Config are shown below and in FIG. 9:Table 2<>_

[0146] In particular, Table 2 shows PUSCH-Config structure changes to introduce dynamic PUSCH repetitions.

[0147] 2. DL (PDSCH) Repetitions

[0148] The scope of this IR is applicable to Resource Allocation in Time domain that considers UE specific PDCCH search space for PDSCH repetition scheduling. FIG. 10 shows the section from 3GPP TS 38.214 that specifies the PDSCH TDRA to be applied in scope of the embodiments described herein.

[0149] Table 3 provided below and in FIG. 11 shows proposed changes to PDSCH-Config structure in RRC configuration to enable dynamic PDSCH repetition scaling.

[0150] Structural elements of PDSCH-Config are highlighted as items 1102, 1104, and 1106.Table 3<>

[0151] Thus Table 3 shows changes to the PDSCH-Config structure in an RRC configuration to enable dynamic PDSCH repetition scaling.

[0152] The flow diagram in FIG. 12 shows the NW side handling of dynamically scaled PDSCH repetitions. The NW will be synchronized to the UE implicitly when the repetitions are scaled up or scaled down as the same set of rules are evaluated on both sides of the radio interface for L1 / L2 scheduling. FIG. 12 shows an example logic flow of dynamic PDSCH repetition scaling at the NW side.

[0153] NW Processing of Dynamic PDSCH repetition scaling (see FIG. 12):

[0154] Step 1 : NW sends to the UE, RRC Reconfiguration with PDSCH-config information containing, skip repetition configuration consisting of a repetition scaling factor. Thresholds to check for scaling repetition count.

[0155] Step 2: NW transmits DL grant in PDCCH DCI. DCI_format_l_0 / DCI_foimat_l_l will contain the Time domain resource assignment which carries the row index of the PDSCH-TimeDomainResourceAllocationList-r20 configuration.

[0156] Described herein are example embodiments where the network sets rules and / or policies for scaling PDSCH repetitions and the repetition scaling factor and thresholds that are part of the Rules / Policies are configured in the TDRA configuration contained in PDSCH-TimeDomainResourceAllocationList-r20.

[0157] Step 3: Following the PDCCH grant, the NW transmits PDSCH repetitions according to TDRA index in DCI.

[0158] Step 4: Policy Rules in the TDRA configuration allow the NW to scale the PDSCH repetitions to a configured level.

[0159] Step 5: NW checks the Rules / conditions and thresholds during the transmission of repetitions and / or at the time of processing the new PUSCH grants. NW determines if a particular Rule / condition or a combination of conditions are met for scaling the original repetition factor configured.

[0160] Step 6: If any one, or combination of the configured conditions are met, the NW decides to scale the PDSCH repetitions by the amount configured in pdsch-RepetitionScalingFactor.

[0161] If conditions are not met, then UE continues its PUSCH repetitions according to Step 3, or follows the number of PUSCH repetitions as configured in pdsch-AggregationF actor.

[0162] In one example (with reference to Table 3 of FIG. 11), if the pdsch-AggregationF actor was set to n8, and the TDRA index indicated in DCI pointed to a configuration with pdsch-RepetitionScalingF actor set to n4, if the conditions / thresholds in pdsch-AggregationScalingThresholds-r20 contained in PDSCH-Config are met, the NW will set the number of PDSCH repetition counts to n4. This means that the PDSCH repetitions are reduced as per Policy rules / conditions.

[0163] The flow diagram in FIG. 13 shows the UE side handling of dynamically scaled PDSCH repetitions from the NW. The rules and thresholds exchanged between NW and UE at RRC configuration serve as a guidance for the UE to adjust its receive window for number of PDSCH repetitions that can be scaled up or scaled down according to evaluation of configured rules and thresholds. FIG. 13 thus shows a logic flow of dynamic PDSCH repetition scaling at the UE side.

[0164] UE Processing of Dynamic PDSCH repetition scaling (see FIG. 13)

[0165] Step 1: UE receives RRC Reconfiguration with PDSCH-config information containing, Skip repetition configuration consisting of a repetition scaling factor. Thresholds to check for scaling repetition count.

[0166] Step 2: UE receives DL grant in PDCCH DCI. DCI_format_l_0 / DCI_format_l_l will contain the Time domain resource assignment which carries the row index of the (Novel) PDSCH-TimeDomainResourceAllocationList-r20 configuration.

[0167] Aspects introduced by the examples described herein include that the UE receives rules / policies for scaling PDSCH repetitions and the repetition scaling factor and thresholds that are part of the Rules / Policies are configured in the TDRA configuration contained in PD S CH-T imeD omainResource All ocati onLi st-r20.

[0168] Step 3 : Following the PDCCH grant, the UE receives PDSCH repetitions accordingto TDRA index in DCI.

[0169] Step 4: Policy Rules in the TDRA configuration allow the NW to scale the PDSCH repetitions to a configured level.

[0170] Since the UE and NW are both working on the same set of Policy rules for repetitions, the evaluation of conditions pertaining to that will be happening on both sides.

[0171] Step 5: UE evaluates the Rules / conditions and thresholds during the transmission of repetitions and / or at the time of processing the new PUSCH grants. NW determines if a particular Rule / condition or a combination of conditions are met for scaling the original repetition factor configured.

[0172] Step 6: If any one, or combination of the configured conditions are met, the UE expects the NW to scale the PDSCH repetitions by the amount configured in pdsch-RepetitionScalingFactor.

[0173] If conditions are not met, then UE expects that the NW continues its PDSCH repetitions according to Step 3, or follows the number of PDSCH repetitions as configured in pusch-AggregationF actor.

[0174] In one example (with reference to Table 3 of FIG. 11), if the pdsch-AggregationF actor was set to n8, and the TDRA index indicated in DCI pointed to a configuration with pdsch-RepetitionScalingF actor set to n4, (Novel) if the conditions / thresholds in pdsch-AggregationScalingThresholds-r20 contained in PDSCH-Config are met, the NW will set the number of PDSCH repetition counts to n4. This means that the PDSCH repetitions are reduced as per Policy rules / conditions.

[0175] The preferred embodiment is that the skipped repetitions are the last subset of the repetitions, but the skipped repetitions could also be specified as a specific noncontiguous set, for example every other repetition to preserve time diversity, while still reducing energy usage and interference. This noncontiguous option might be used for example with the PDSCH where the ACK / NACK timing is regardless aligned with the latest possible repetition within the bundle.

[0176] It is possible to also shift the HARQ ACK / NACK Tx timing by the UE in response to the above approach for the PDSCH.

[0177] FIG. 14A and FIG. 14B illustrate how the HARQ ACK / NACK Tx timing can be scaled as an offset to the last PDSCH repetition after PDSCH repetition scaling is done. In this illustration the offset KI considered from the last scaled PDSCH repetition i.e. after the 2nd PDSCH repetition. Alternatively, a KI offset corresponding to a scaled PDSCH repetition can also be configured by RRC configuration in the TDRA tables by having an additional entry for a KI offset corresponding to a scaled repetition count. Steps and configurations are shown in FIG. 14A and FIG. 14B. FIG. 14A and FIG. 14 thus together show a signaling flow diagram for PDSCH repetition for each HARQ Process with KI factor scaled depending on scaled PDSCH repetition count

[0178] The following is an explanation of the message sequence flow (of FIG. 14A and FIG. 14B) between UE and NW side for PDSCH repetition scaling which is applicable to each active HARQ process:

[0179] The UE 110 and gNB 170 (the NW) are in an RRC CONNECTED mode or state.

[0180] Step 1 : UE capability information is transmitted from UE 110 to NW 170 to indicate its support of repetition scaling, in an example by the UE 110 indicating to the NW 170 ‘(pdsch-RepetitionScaling: supported)’ as shown in FIG. 14A.

[0181] Step 2: gNB 170 determines UE’s scaled repetition capability.

[0182] Step 3: RRC Reconfiguration from NW to UE to configure Rel-20 TDRA tables with additional rows having PUSCH repetition scaling factors, Beta Offsets, KI offset for ACK / NACK, and Policy Rules and / or their combinations to enable evaluation of scaling of PDSCH repetitions. In particular, the gNB 170 transmits to the UE 110 an RRC reconfiguration (with Rel-20 TDRA tables, conditions, thresholds and timers, and KI offset for dynamic PDSCH repetition scaling).

[0183] Steps 4-6: UL (and DL) data transfer between UE and NW, and evaluation of SINR conditions on the NW side to enable PDSCH repetitions.

[0184] Step 4: the UE 110 and gNB 170 perform data transfer.

[0185] Step 5: the gNB 170 determines that SINR conditions are met to enable PDSCH repetition.

[0186] Step 6: the UE 110 and gNB 170 perform activation of PDSCH repetition.

[0187] Steps 7-13: DCI from NW indicates that legacy PDSCH repetition procedure is followed with legacy KI factor, and repetition factor of 4.

[0188] Step 7: the gNB 170 transmits to UE 110 a PDCCH (DCI_l_0 / DCI_l_l, HARQ Process Id#n, R-20 TDRA index with pdsch-AggregationFactgor=4, BetaOffsets).

[0189] Step 8: gNB 170 transmits to UE 110 PDSCH repetition 1.

[0190] Step 9: gNB 170 transmits to UE 110 PDSCH repetition 2.

[0191] Step 10: gNB 170 transmits to UE 110 PDSCH repetition 3.

[0192] Step 11 : gNB 170 transmits to UE 110 PDSCH repetition 4.

[0193] Step 12 (where Step 12 is at least after Step 11 and before Step 13): KI is configured to start from last PDSCH repetition.

[0194] Step 13 : UE 110 transmits to gNB 170 a PUCCH (ACK / NACK).

[0195] Steps 14-19: Evaluation of Policy Rules defined by NW for repetition scaling and configured to the UE in Step 2, yield a decision on UE (and NW) to move to a scaled PDSCH repetition mode. In this example it is a reduction in PDSCH repetition from n4 to n2. The KI offset for ACK / NACK from UE to NW is also scaled by the UE to offset KI slots from the latter (scaled) PDSCH repetition as shown in Step 18.

[0196] Step 14: UE 110 decides scaling of (HARQ Process Id#n) PDSCH repetition to 2x, and looks up a TDRA Rel-20 Configuration matching the repetition number for the evaluated condition, and gNB 170 decides scaling of PDSCH repetition to 2x, and looks up a TDRA Rel-20 configuration matching the repetition number for the evaluated condition.

[0197] Step 15: UE 110 prepares for dynamic scaling of PDSCH repetition Tx and optionally starts a configured timer for repetition scaling, and gNB 170 prepares for dynamic scaling of PDSCH repetition Tx and optionally starts a configured timer for repetition scaling.

[0198] Step 16: gNB 170 transmits to UE 110 PDSCH repetition 1.

[0199] Step 17: gNB 170 transmits to UE 110 PDSCH repetition 2.

[0200] Step 18 (where Step 18 is at least after Step 17 and before Step 19): KI is configured to start from the (scaled) last PDSCH repetition count.

[0201] Step 19: UE 110 transmits to gNB 170 a PUCCH (ACK / NACK) for HARQ Process Id#n.

[0202] 3. Handling of (fallback) cases where the signaling triggering the repetition switching was lost / not received

[0203] The gNB already provides for and handles multiple situations where there is potential need for fall back handling this signaling lost / UE / NW state mismatch problem, where some signaling between the UE and the NW is not received, such that the receiver may not know that the transmitter sent that signaling message.

[0204] This signaling lost and / or UE / NW state mismatch is handled with (1-3):

[0205] 1) 3 GPP skippable PUSCH has fallback handling where it performs DTX detection to handle the case where, for example the PDCCH DCI grant was lost such that the UE does not transmit on the PUSCH. With repetitions, this DTX detection is normally done across all of the repetitions. However, with the methods described herein, the network can additionally / separately perform this DTX detection on the last four repetitions as a part of an implementation, as a fallback approach for this existing case where some signaling between the UE and the NW is not received, such that the receiver may not know that the transmitter sent that signaling message.

[0206] 2) DRX inactivity timer, where the handset will not restart the DRX inactivity timer if it did not receive a PDCCH DCI, but the network doesn't immediately know that the UE did not receive that PDCCH DCI. In this case, the network can later observe if the UE transmitted / received on the UL / DL grant provided by that DCI as further fallback approach for this existing case where some signaling between the UE and the NW is not received, such that the receiver may not know that the transmitter sent that signaling message.

[0207] 3) DFT-S OFDM switching, where the network already performs multiple hypothesis decoding in multiple situations, e.g. where it attempts to receive the PUSCH with both DFT-S-OFDM and CP OFDM where there is some ambiguity with respect to the waveform switching time. Similarly, the multiple hypothesis decoding approach is anotherfallback option which can be used in an implementation dependent way within the network if needed - where some signaling between the UE and the NW is not received, such that the receiver may not know that the transmitter sent that signaling message.

[0208] Thus, described herein are embodiments where thresholds for scaling of repetitions are set up according to Table 1 of FIG. 5, including the syntax shown at item 502 of FIG. 5. These thresholds are configured to the UE by the NW via RRC signaling. The network and the UE monitor these thresholds. In the PDSCH repetition scaling case, when the network has to schedule repetitions of PDSCH towards the UE on a HARQ process, the thresholds are evaluated to check if repetitions can be scaled. The UE also evaluates these rules independently for the HARQ process, and since the thresholds are mutually agreed upon, the UE also expects the network to scale the repetitions when the thresholds for scaling them are met. The amount of scaling of repetitions depends on the range or value of repetition count in the TDRA table index that was indicated in the DCI signaling that scheduled the PDSCH grant for the HARQ process.

[0209] Uplink repetitions are from the UE to the NW. The repetitions have to be determined from the rules that are configured, and the scaling is applied according to the range of repetitions present in TDRA table index that is indicated in the DCI that schedules the HARQ process. The amount of scaling within the range is determined by the evaluation of thresholds. Thresholds are configured as one or more of a) previous AL history, b) CQI measurement history, c) number of HARQ reps on prior HARQ process, d) MCS indicated in the DCI of subsequent HARQ process that is scheduled by a subsequent DCI.

[0210] When the radio conditions are worse off (compared to configured thresholds) than when the DCI signal / indication for the repetitions was received by the UE, and / or the AL history of the DCI decoding on the HARQ process indicates higher AL (compared to configured thresholds), and / or the number of reps indicated by the DCI on another HARQ process is higher than the currently indicated number of reps on the DCI for the current HARQ process, and / or the MCS indicated by the DCI for the other HARQ process is lower than the currently indicated MCS on the DCI indication for the current HARQ process, then the repetitions of PUSCH (i.e. uplink reps) should be scaled up (based on the configured higher rep count in the range of reps), meaning that there is need to repeat more to get better chance of PUSCH to be decoded at the network, and the repetitions of PDSCH (i.e. downlink reps) should be scaled up (based on the configured higher rep count in the range of reps), meaningthat there is need to repeat more to get better chance of PDSCH to be decoded at the UE.

[0211] Conversely, if radio conditions are better (compared to configured thresholds) than when the DCI signal / indication for the repetitions was received by the UE, and / or the AL history of the DCI decoding on the HARQ process indicates lower AL (compared to configured thresholds), and / or the number of reps indicated by the DCI on another HARQ process is lower than the currently indicated number of reps on the DCI for the current HARQ process, and / or the MCS indicated by the DCI for the other HARQ process is higher than the currently indicated MCS on the DCI indication for the current HARQ process, then the repetitions of PUSCH (i.e. uplink reps) should be scaled down (based on the configured lower rep count in the range of reps), meaning that there is need to repeat less for a good chance of PUSCH to be decoded at the network, and the repetitions of PDSCH (i.e. downlink reps) should be scaled down (based on the configured lower rep count in the range of reps), meaning that there is need to repeat less for a good chance of PDSCH to be decoded at the UE.

[0212] 4. Advantages, technical effects, and benefits of Implicit Repetition Scaling

[0213] Advantages, technical effects, and benefits of implicit repetition scaling include that the examples described herein provide ability to, without extra HARQ signaling, rescale the number of repetitions in a more timely and dynamic fashion, e.g. after the repetitions have started so as to avoid UE transmission (or reception) of extra repetitions, based on new information that becomes available after the DCI scheduling the (CG or DG) repetition allocation, which is available at both the UE and the NW, so the e.g. UE (and NW) energy (and interference) can be conserved.

[0214] UE energy benefit applies if e.g. the number of repetitions is reduced, e.g. where not needed for URLLC PUSCH. This is in contrast to where the UE must Tx all (or none with skippable UL grant) of the repetitions within a “bundle” (due to a single DCI). This new IR allows the UE to send just some subset, thereby saving UE energy (i.e. skippable repetitions). Where repetitions are particularly likely to be used in cases where there is an elevated need to conserve energy. For example (1-3): 1) Cell edge UEs consume significantly higher Tx power bit where transmitting to gNB where there is additional fading etc. The 3GPP standard model has a parameter for this. This is value is also quantized where the UE signals this value to the NW, 2) NTN links are also more energy constrained at both the UE (increased UE Tx power) and at the gNB (as it is a Satellite), 3) URLLC and other high-priority can also bemore sensitive to energy consumption at both the UE (increased UE Tx power) and at the gNB e.g. as the service may be for public safety, and be expected to work even during power outages.

[0215] Reduced interference on DL (and UL) resulting from reduced PDSCH (and PUSCH) repetitions, and possibly reducing the PDCCH and other signaling needed.

[0216] Reduced scheduler blocking - Transmitting less repetitions where possible can avoid needlessly displacing PRBs usage by other UEs and services. If there is a collision then the NW detects elevated energy and throws out those 4 slots.

[0217] DCI Signaling Overhead reduction e.g.: in the expand / increase repetitions case -Avoids extra DCI, and provides extra repetitions when needed, adding those extra repetition allocations implicitly when they are more likely needed) is benefit if IR expands or shrinks the size of the allocation that the DCI granted - on the fly / i.e. when likely needed. In the shrink / reduce repetitions case - Avoids extra DCI or early termination signaling while still avoiding extra repetitions when needed.

[0218] The examples described herein may be applicable to 6G and beyond, to Rel-20, and to a larger group 6G technology that focuses on repetitions, and / or a dynamic implicit trigger structure: Dynamically avoiding Tx of latter repetitions based upon implicit triggers at both UE and NW, saving UE and NW energy, many of which also relate to repetitions.

[0219] The examples described herein may be applicable to 3 GPP, including 3 GPP TS 38.331 and 3GPP TS 38.213.

[0220] As used herein, met, satisfied, and fulfilled may be used interchangeable. For example, if the conditions for determining a repetition count (e.g. a scaled repetition count) are met, then the conditions for determining the repetition count are satisfied and are also fulfilled.
