Description

Background Technology

[0001] User equipment (UE) can establish connections with at least one of several different networks or network types (e.g., a Public Land Mobile Network (PLMN) operating a Radio Access Network (RAN)). A non-terrestrial network (NTN) refers to a network that utilizes non-terrestrial components (e.g., one or more satellites) to provide UEs with access to the PLMN.

[0002] Satellites or other components in an NTN network may have limited power; for example, satellites can recharge themselves via deployed solar panels. Furthermore, satellites may need to transmit numerous beams over their large coverage areas (e.g., hundreds, thousands, or millions of square kilometers). Therefore, each beam may have limited transmission power. Due to these limitations, downlink coverage enhancements for NTN networks are required. Summary of the Invention

[0003] Some example implementations relate to an apparatus having processing circuitry configured to process, based on signals received from the network, the Type 0 PDCCH common search space set (CSS) for scheduling System Information Blocks (SIBs) in the Physical Downlink Shared Channel (PDSCH) for the Physical Downlink Control Channel (PDCCH) and the configuration of whether to transmit the associated Type 0 PDCCH CSS, which includes the SIBs in the PDSCH, during PDCCH repetition, and to decode the symbols associated with the Type 0 PDCCH CSS and the associated Type 0 PDCCH CSS based on signals received from the network when the configuration indicates transmission of the associated Type 0 PDCCH CSS.

[0004] Other example embodiments relate to an apparatus having processing circuitry configured to process, based on signals received from a network, a first configuration for processing a reference signal transmission power for a reference signal transmitted by the network and a power control offset between two different types of reference signals; a second configuration for processing, based on signals received from the network, an indication of an increase or decrease in the reference signal transmission power of one of the two different types of reference signals; and to determine the path loss of one of the two different types of reference signals based on the reference signal transmission power and the increase or decrease in the reference signal transmission power of the one of the two different types of reference signals.

[0018] The example implementation can be further understood by referring to the following description and related figures, wherein the same elements have the same reference numerals. The example implementation relates to downlink (DL) coverage enhancement for NTN networks. Specifically, DL coverage enhancement can be at the link level for frequency range 1 NTN (FR1-NTN) (e.g., for the Physical Downlink Control Channel (PDCCH) or Physical Downlink Shared Channel (PDSCH)), or as a system-level enhancement for FR1-NTN or frequency range 2 NTN (FR2-NTN), which can allow dynamic and flexible power sharing across the entire satellite coverage area between satellite beams or different satellite beam patterns / sizes (e.g., wide or narrow).

[0019] Example embodiments are described with reference to user equipment (UE). However, references to the UE are provided for illustrative purposes only. The example embodiments may be used with any electronic components capable of establishing a connection to a network and configured with hardware, software, and / or firmware for exchanging information and data with the network. Therefore, the UE described herein is used to represent any suitable electronic component.

[0020] Example implementations are also described with reference to 5G New Radio (NR) networks. However, the reference to 5G NR networks is provided for illustrative purposes only. The example implementations can be used with any network capable of establishing a connection with the UE and exchanging information and data with the UE (e.g., 5G-Advanced networks, 6G networks, etc.).

[0021] The example implementation is described with reference to a 5G NR network integrated with a non-terrestrial network (NTN) that utilizes one or more satellites to provide UEs with access to a 5G NR radio access network (RAN). The satellite-based NTN can be deployed by a Public Land Mobile Network (PLMN) and can be further integrated with the PLMN's terrestrial network (TN). Throughout this description, non-terrestrial components are generally described as satellites. However, any reference to satellites is for illustrative purposes only, and the example implementation can be applied to other types of non-terrestrial components, such as aircraft, unmanned aerial vehicles (UAVs), etc.

[0022] The example implementations involve PDCCH repetition, PDSCH repetition, and PDSCH extension in an NTN network. PDCCH repetition can be applied to broadcast PDCCH transmissions and UE-specific PDCCH transmissions. The example implementations also involve reference signal transmission power in an NTN network. Each of these example implementations will be described in more detail below.

[0023] Figure 1An example network arrangement 100 according to various example implementations is shown. The example network arrangement 100 includes a UE 110. The UE 110 can be any type of electronic component configured to communicate via a network, such as a mobile phone, tablet computer, desktop computer, smartphone, phablet, embedded device, wearable device, Internet of Things (IoT) device, etc. A real network arrangement can include any number of UEs used by any number of users. Therefore, the example of a single UE 110 is provided for illustrative purposes only.

[0024] UE 110 can be configured to communicate with one or more networks. In the example of network deployment 100, the network with which UE 110 can wirelessly communicate is the 5G NR Radio Access Network (RAN) 120. However, UE 110 can also communicate with other types of networks (e.g., 5G cloud RAN, Next Generation RAN (NG-RAN), LTE RAN, legacy cellular networks, WLAN, etc.), and UE 110 can also communicate with the network via a wired connection. Referring to the example implementation, UE 110 can establish a connection with 5G NR RAN 120. Therefore, UE 110 may have a 5G NR chipset to communicate with NR RAN 120.

[0025] The 5G NR RAN 120 can be part of a public terrestrial mobile network (PLMN) that can be deployed by network operators (e.g., Verizon, AT&T, T-Mobile, etc.). The 5G NR RAN 120 may include, for example, cells or base stations (Node B, eNodeB, HeNB, eNB, gNB, gNodeB, macro cell, micro cell, small cell, femtocell, etc.) configured to transmit and receive services from UEs equipped with appropriate cellular chipsets.

[0026] In network deployment 100, 5G NR RAN 120 includes base stations (e.g., gNB 120A) that can be deployed in a terrestrial network (TN) or a non-terrestrial network (NTN). For example, satellite-based systems can be integrated with 5G NR RAN 120 to provide network access to UE 110 in an NTN deployment, and in some cases, the base stations can be located on non-terrestrial components (e.g., satellites). References will follow below. Figure 4 A more detailed description of the example NTN network architecture is provided.

[0027] return Figure 1 The network deployment 100 and gNB 120A may include one or more communication interfaces to exchange data and / or information with UE 110, the corresponding 5G NR RAN 120, cellular core network 130, Internet 140, etc.

[0028] UE 110 can connect to 5G NR-RAN 120 via gNB 120A. Any association procedure can be performed to connect UE 110 to 5G NR-RAN 120. For example, as discussed above, 5G NR-RAN 120 can be associated with a specific cell provider where UE 110 and / or its user have protocol and credential information (e.g., stored on a SIM card). Upon detecting the presence of 5G NR-RAN 120, UE 110 can send the corresponding credential information to associate with 5G NR-RAN 120. More specifically, UE 110 can be associated with a specific cell (e.g., gNB 120A). However, as mentioned above, the reference to 5G NR-RAN 120 is for illustrative purposes only, and any suitable type of RAN can be used.

[0029] In addition to the 5G NR RAN 120, network deployment 100 also includes a cellular core network 130, an Internet 140, an IP Multimedia Subsystem (IMS) 150, and a network service backbone 160. The cellular core network 130 can be viewed as a set of interconnected components that manage the operation and traffic of the cellular network. The cellular core network 130 also manages the traffic flowing between the cellular network and the Internet 140.

[0030] IMS 150 can generally be described as an architecture for delivering multimedia services to UE 110 using the IP protocol. IMS 150 can communicate with cellular core network 130 and the Internet 140 to provide multimedia services to UE 110. Network service backbone 160 communicates directly or indirectly with the Internet 140 and cellular core network 130. Network service backbone 160 can generally be described as a collection of components (e.g., servers, network storage deployments, etc.) that implement a set of services that can be used to extend the functionality of UE 110 in communicating with various networks.

[0031] Figure 2 Example UE 110 according to various example implementations is shown. (Refer to...) Figure 1 The network layout 100 is used to describe UE 110. UE 110 may include a processor 205, a memory layout 210, a display device 215, an input / output (I / O) device 220, a transceiver 225, and other components 230. Other components 230 may include, for example, audio input devices, audio output devices, power supplies, data acquisition devices, ports for electrically connecting UE 110 to other electronic devices, etc.

[0032] Processor 205 may be configured to execute multiple engines of UE 110. For example, an engine may include DL coverage engine 235. DL coverage engine 235 may perform various operations related to receiving PDCCH and PDSCH repetitions in an NTN network. To provide some general examples, DL coverage engine 235 may perform operations such as, but not limited to, determining the use of PDCCH repetition, determining the location of a search space set for PDCCH repetition, determining the use of PDSCH repetition, and determining the location of a search space set for PDSCH repetition. These and other operations are described in more detail below.

[0033] The engine 235 referenced above is provided as an application (e.g., a program) executed by processor 205 for illustrative purposes only. The functionality associated with engine 235 may also be represented as a separate, integrated component of UE 110, or as a modular component coupled to UE 110, such as an integrated circuit with or without firmware. For example, the integrated circuit may include input circuitry for receiving signals and processing circuitry for processing signals and other information. The engine may also be embodied as one application or multiple independent applications. Furthermore, in some UEs, the functionality described for processor 205 is split between two or more processors, such as a baseband processor and an application processor. Example implementations may be implemented according to any of these or other configurations of the UE.

[0034] Memory arrangement 210 may be a hardware component configured to store data related to operations performed by UE 110. Display device 215 may be a hardware component configured to display data to a user, while I / O device 220 may be a hardware component enabling a user to input data. Display device 215 and I / O device 220 may be separate components or may be integrated together (such as a touchscreen).

[0035] Transceiver 225 may be a hardware component configured to establish connections with 5G NR-RAN 120, LTE-RAN (not shown), legacy RAN (not shown), WLAN (not shown), etc. Accordingly, transceiver 225 may operate on a variety of different frequencies or channels (e.g., a continuous set of frequencies). Transceiver 225 includes circuitry configured to transmit and / or receive signals (e.g., control signals, data signals). Such signals may be encoded using information used to implement any of the methods described herein. Processor 205 may be operatively coupled to transceiver 225 and configured to receive signals from and / or transmit signals to transceiver 225. Processor 205 may be configured to encode and / or decode signals (e.g., signaling from a base station in the network) for use in implementing any of the methods described herein.

[0036] Figure 3 An example base station 300 is shown according to various example implementation schemes. Base station 300 may represent a gNB 120A or any other type of access node that UE 110 can use to establish connections and manage network operations.

[0037] Base station 300 may include processor 305, memory arrangement 310, input / output (I / O) devices 315, transceiver 320, and other components 325. Other components 325 may include, for example, audio input devices, audio output devices, batteries, data acquisition devices, ports for electrically connecting base station 300 to other electronic devices and / or power sources, TxRU, transceiver chains, antenna elements, antenna panels, etc.

[0038] Processor 305 may be configured to execute multiple engines of base station 300. For example, an engine may include DL coverage configuration engine 330. DL coverage configuration engine 330 may perform various operations related to configuring PDCCH repetition and PDSCH repetition for the UE. To provide some general examples, DL coverage configuration engine 330 may perform operations such as, but not limited to, configuring PDCCH repetition for the UE, configuring PDSCH repetition for the UE, and configuring reference signal transmission power for the UE. These and other operations are described in more detail below.

[0039] The engine 330 described above is merely an example of an application (e.g., a program) executed by the processor 305. The functionality associated with the engine 330 can also be represented as a separate integrated component of the base station 300, or as a modular component coupled to the base station 300, such as an integrated circuit with or without firmware. For example, the integrated circuit may include input circuitry for receiving signals and processing circuitry for processing signals and other information. Furthermore, in some base stations, the functionality described for the processor 305 is split among multiple processors (e.g., a baseband processor, an application processor, etc.). Example implementations can be implemented according to any of these or other configurations of the base station.

[0040] The memory arrangement 310 may be a hardware component configured to store data related to operations performed by the base station 300. The I / O device 315 may be a hardware component or port that enables a user to interact with the base station 300.

[0041] Transceiver 320 may be a hardware component configured to exchange data with UE 110 and any other UE in network arrangement 100. Transceiver 320 may operate on a variety of different frequencies or channels (e.g., a continuous set of frequencies). Therefore, transceiver 320 may include one or more components to enable data exchange with various networks and UEs. Transceiver 320 includes circuitry configured to transmit and / or receive signals (e.g., control signals, data signals). Such signals may be encoded using information used to implement any of the methods described herein. Processor 305 may be operatively coupled to transceiver 320 and configured to receive signals from and / or transmit signals to transceiver 320. Processor 305 may be configured to encode and / or decode signals (e.g., signaling from a UE) for use in implementing any of the methods described herein.

[0042] Figure 4 An example non-terrestrial network (NTN) architecture 400 is illustrated according to various example implementation schemes. NTN can refer to any network that uses non-terrestrial components such as satellites, aircraft, unmanned aerial vehicles (UAVs), etc. to provide network services to user terminals.

[0043] NTN architecture 400 represents a network arrangement including one or more satellites. In this example, it shows two satellites 410 and 420 integrated with a radio access network (RAN) 440. RAN 440 can be, for example, as described above... Figure 1 The 5G NR RAN 120 is described. The NTN architecture 400 includes a gateway 430 that connects the terrestrial network 440 to the NTN components. Figure 4 In the NTN architecture 400, gateway 430 and satellites 410 and 420 communicate via a feeder link. In some NTN deployments, satellites may be served by several gateways simultaneously.

[0044] Satellites 410 and 420 provide network services to UE 110 via a serving link (not shown). Satellites 410 and 420 may implement transparent payloads or regenerative payloads. A transparent payload refers to an arrangement in which satellites 410 and 420 receive signals and transmit an amplified version of those signals while performing frequency conversion. For example, satellite 410 may receive uplink communication from UE 110 at the serving link frequency and transmit an amplified version of the signal to gateway 430 at the feeder link frequency, or it may receive downlink communication via gateway 430 at the feeder link frequency and transmit an amplified version of the signal to UE 110 at the serving link frequency. A regenerative payload refers to an arrangement in which satellites 410 and 420 act as distributed units (DUs) or base stations (e.g., gNBs), where received signals are regenerated using signal processing techniques (e.g., demodulation, decoding, handover, encoding, modulation, etc.) before retransmission.

[0045] refer to Figure 1 In a regenerative payload arrangement, gNB 120A may be located in an aerospace component (e.g., Figure 4 On satellites 410 and / or 420. In a transparent payload arrangement, gNB 120A may be located on the ground, and satellites 410 and 420 are used to mirror the signal between gNB 120A and UE 110, as described above. In either case, in the example implementation, satellites 410 and 420 may transmit signals including the same PCI, as will be described in more detail below.

[0046] Figure 4 The example NTN architecture 400 shown is not intended to limit the example implementation in any way. NTNs can be integrated with 5G NR RAN and / or other networks in any of a variety of ways. For example, a typical satellite-based NTN may include a low Earth orbit (LEO) constellation comprising a range of satellites and gateways with extensive interconnectivity via ground-to-ground (G2G) links, satellite-to-satellite (S2S) links, ground-to-satellite (G2S) links, and satellite-to-ground (S2G) links. Other types of satellite-based NTNs may include geostationary orbit (GEO) satellites or medium Earth orbit (MEO) satellites.

[0047] Different types of NTNs each have their own advantages and disadvantages and can be deployed in various scenarios, depending on the objectives to be achieved, such as broad coverage across large areas, concentrated coverage in urban environments, or along high-traffic routes. Therefore, Figure 4 The NTN architecture 400 described herein is provided for illustrative purposes only.

[0048] As described above, some example implementations involve link-layer enhancements for FR1-NTN, such as enhancements to PDCCH and PDSCH. Example implementations describe enhancements to broadcast PDCCH and PDSCH related to System Information Block (SIB) operation. Broadcast PDCCH can provide scheduling for SIBs including SIB1. The broadcast can be a Type 0 PDCCH common search space (CSS) set using Downlink Control Information (DCI) format 1_0, where Cyclic Redundancy Check (CRC) is scrambled by System Information-Radio Network Temporary Identifier (SI-RNTI). The Main Information Block (MIB) includes pdcch-ConfigSIB1, which includes a controlResourceSetZero information element (IE) and a searchSpaceZero IE. SIB1 is included in the broadcast PDSCH and includes a PDCCH-ConfigCommon IE, which includes a searchSpaceSIB1 IE and a searchSpaceZero IE. In other example implementations, the PDCCH broadcast may be a Type 0A PDCCH CSS set with DCI format 1_0, where the CRC is scrambled by SI-RNTI. SIB1 may include a PDCCH-ConfigCommon IE, which includes a searchSpaceOtherSystemInformationIE. As will be described in more detail below, UE operation related to these PDCCH and PDSCH broadcasts can be enhanced to improve DL coverage against the NTN.

[0049] Some aspects of the exemplary implementation involve the design of predefined PDCCH monitoring timing for the type 0 CSS set. The example implementation is described with reference to a specific Time Division Multiplexing (TDM) implementation (e.g., a network without shared spectrum channel access and SSB-CORESET multiplexing mode 1).

[0050] Figure 5Example table 500, including predefined PDCCH monitoring timings for type 0 CSS sets, is shown according to various example implementations. As described above, the MIB broadcast by the network may include a searchSpaceZero IE, for example, 4 bits, corresponding to the values ​​(e.g., 0 to 15) of the index in table 500. This index includes a configuration that instructs the UE to schedule the PDCCH for SIB1. The configuration for each index may include a value (O) of the slot offset relative to the start of the frame, the number of search space sets per slot, a variable (M) related to the number of search space sets per slot, a first symbol index of the first search space set, and a first symbol index of the associated search space set. This configuration will be described in more detail below.

[0051] In the first case, the example implementation can expand the number of search space sets per time slot for those indexes that currently have only one search space set per time slot. This expansion can be applied to the indexes {0, 2, 4, 6, 8, 9, 10, 11, 12, 13, 14, 15} in Table 500, which currently have only one search space set per time slot.

[0052] In some example implementations, the associated search space set can be defined in the same time slot as the original search space set, for example, repeated in the same time slot. This is shown in Table 500 for the indexes {0, 2, 4, 6, 8, 9, 10, 11, 12, 13, 14, 15}, where the number of search space sets per time slot is defined as "1, 2 (if repeated)". Therefore, in these example implementations, if repetition is enabled, the search space set used for the listed indexes will be enhanced from one search space set (e.g., the original search space set referred to as the first search space set in Table 500) to two search space sets: the original search space set plus the associated search space set as the repeated search space set. The configuration for this associated search space set is shown in the rightmost column of Table 500.

[0053] In the first option, repetition can begin at the first symbol after the end of the first search space set. Figures 6A to 6C An example time-slot diagram illustrating an associated search space set starting at the first symbol after the end of the first search space set, according to various example implementation schemes, is shown.

[0054] Figure 6A A slot diagram 600 applicable to indices 0, 2, 4, 6, 8, and 9 is shown. In this example, the number of symbols used for the search space is three (3), for example, For example, slot diagram 600 can be applied to index 0 of table 500. The configuration of index 0 indicates that the first symbol index of the first search space set is 0. Therefore, the first 3 symbols of slot 600 are the original search space (SS) #0 602. Associated SS#0 604 begins at the first symbol after the end of SS#0 602, for example, symbol index 4. Figure 6A The diagram also shows a symbol for PDSCH 606, which includes SIB1.

[0055] Figure 6B The time slot diagram 610, which can be applied to indices 10, 12, and 14, is shown. Figure 6C Time slot diagram 620, which can be applied to indices 11, 13, and 15, is shown. Time slot diagrams 610 and 620 are similar to time slot diagram 600, except that the starting symbol used for SS#0 is different.

[0056] In the second option, repetition can begin at multiple symbols after the end of the first search space set. For example, refer to... Figure 6A In the time slot diagram 600, associated SS#0 does not start at symbol 4, but can start at a symbol greater than symbol 4. For example, there is a symbol gap between the end of SS#0 and the start of associated SS#0.

[0057] In other example implementations related to enhancing the listed indexes from one search space set to two search space sets, the associated search space set may be applied in a later time slot, e.g., repeated across time slots. In these example implementations, the same search space symbol position of the original SS#0 is applied to a later time slot. Similarly, the same PDSCH with the SIB1 symbol position is applied to a later time slot, e.g., PDSCH is repeated.

[0058] Figure 7 Example slot diagram 700 illustrates an association search space set in a slot later than the first search space set, according to various example implementations. Figure 7 In the example, the number of symbols used for the search space is three (3), for example, Therefore, time slots The first three symbols are the original SS#0 712. Associated SS#0 732 in the time slot. In the same symbol. Time slots 710 and 730 also include PDSCHs having SIB1 716 and SIB1 736 in the same symbol. Time slot diagram 700 also shows time slots n0+1 720 and n1+1 740, which can have similar designs to the corresponding time slots n0 and n1, for example, for SS#1.

[0059] Therefore, in these example implementations, the UE can monitor the PDCCH in the type0-PDCCH CSS set on two time slots (e.g., n0, n0+1), where The equation for n0 is defined in 3GPP Technical Specification (TS) 38.213, and its use herein is consistent with that definition. In the above equation, O and M are defined above and included in Table 500, i is the SSB index, and μ is the subcarrier spacing (e.g., μ is 0 for 15 kHz SCS, μ is 1 for 30 kHz SCS, μ is 2 for 60 kHz SCS, and so on).

[0060] If the UE detects that PDCCH duplication has been applied, the UE can monitor the PDCCH in the type0-PDCCH CSS set on two additional time slots (e.g., time slots with time slot indices n1 and n1+1), where , where N SSB N represents the number of synchronization signal blocks (SSBs) in an SSB cycle. For example, for L-band or S-band (e.g., NTN band less than 3 GHz), N... SSB It equals 4.

[0061] if If so, then the time slot is in a frame with an even-numbered System Frame Number (SFN) index. If If so, the time slot is in a frame with an odd number of SFN indices.

[0062] Figure 7 The examples shown illustrate indices 0, 2, 4, 6, 8, and 9. However, the principles described herein can also be applied to other indexes, such as an index for SS#0 where the starting symbol is later than the symbol index 0.

[0063] In the second case related to the design of the predefined PDCCH monitoring timing for the type0 CSS set, the example implementation can address those indexes for which two (2) search space sets have been defined, such as indexes {1, 3, 5, 7} in Table 500.

[0064] In an example implementation for the second scenario, an additional set of associated search spaces is defined in a later time slot, for example, repeating across time slots. The same search space symbol position can be applied to a later time slot.

[0065] Figure 8 Example slot diagram 800 illustrates an association search space set in a slot later than the first set of search space sets, according to various example implementations. Figure 8 In the example, the number of symbols used for the search space is three (3), for example, Therefore, time slots The first three symbols are the original SS#0 812 used for SSB#0, and the time slot The next three symbols are the original SS#0 814 for SSB#1, for example, the original two search space sets defined for the indexes {1, 3, 5, 7} in Table 500. The associated SS#0 832 for SSB#0 and the associated SS#0 834 for SSB#1 are in the time slot. The same symbols include, for example, enhancements for indexes {1, 3, 5, 7} in Table 500. Time slots 810 and 830 also include PDSCHs with SIB1 816 and SIB1 836 in the same symbols. Time slot diagram 800 also shows time slots n0+1 820 and n1+1 840, which can have similar designs to their corresponding time slots n0 and n1, for example, for SS#0.

[0066] In these example implementations, the UE can monitor the PDCCH in the type0-PDCCHCSS set on two time slots (e.g., n0, n0+1), where The equation used for n0 is defined in 3GPP Technical Specification (TS) 38.213, and its use in this document is consistent with the definition in that standard.

[0067] If the UE detects that PDCCH duplication has been applied, the UE can monitor the PDCCH in the type0-PDCCH CSS set on two additional time slots (e.g., time slots with time slot indices n1 and n1+1), where , where N SSB This represents the number of SSBs in the SSB cycle.

[0068] if If so, then the time slot is in a frame with an even-numbered (SFN) index. If If so, the time slot is in a frame with an odd number of SFN indices.

[0069] Other aspects of the exemplary implementation involve the design of a default PDSCH time-domain resource allocation (TDRA) for the normal cyclic prefix (CP). As described above, SIB1 can be carried in the PDSCH. The example implementation can support repetition for the PDSCH.

[0070] Figure 9Example Table 900 is shown, illustrating the default PDSCH Time Domain Resource Allocation (TDRA) for normal cyclic prefixes (CP) according to various example implementations. Table 900 shows the table index, columns indicating dmrs-Type A-position, and columns indicating the PDSCH mapping type. Table 900 also shows a column indicating the gap between PDCCH and PDSCH. A value of 0 indicates that PDCCH and PDSCH are in the same time slot. Refer above to Figures 6 to 7. Figure 8 Some examples of this situation are shown. For example, in Figure 7 In the diagram, PDSCH 716 with SIB1 is shown in the same time slot 710 as PDCCH. Column S is the start symbol of PDSCH, and column L is the length of PDSCH. This configuration will be described in more detail below.

[0071] In some example implementations, the extension for TDRA can be applied to the same time slot with PDCCH repetition as described above, or it can be applied to time slots where PDCCH repetition is not used. In these example implementations, some values ​​of L can be modified to support reliable PDSCH transmission. For example, referring to Table 900, for row index 7, the value L changes from 4 to 8 in the case of PDCCH repetition; for row index 10, the value L changes from 2 to 4 in the case of PDCCH repetition; and for row index 16, the value L changes from 4 to 6 in the case of PDCCH repetition.

[0072] Figure 10 Slot diagram 1000 illustrating TDRA extension for PDSCH according to various example implementations is shown. See index 7 of Table 900 for description. Figure 10 Examples are shown. Time slot 1010 on the left shows the original time slot without TDRA extension. Time slot 1020 on the right shows the applied TDRA extension.

[0073] exist Figure 10 In the example, the number of symbols used for the search space of PDCCH is three (3), for example, Therefore, the first three symbols of slot 1010 are the original SS#0 1012. As shown in Table 900, without extension, the starting symbol index of the PDSCH is 6, and its length is 4 symbols. Therefore, slot 1010 shows a PDSCH with SIB1, which starts at symbol index 6 and has a length of 4 symbols.

[0074] However, as Figure 9 As shown, the length L of index 7 can be expanded to a value with 8 symbols. Therefore, Figure 10Slot 1020 illustrates the applied TDRA extension. In this example, PDCCH repetition is also applied. However, PDCCH repetition is not required. Therefore, the first 3 symbols of slot 1020 are the original SS#0 1022, and the next 3 symbols are a repetition of the PDCCH associated with SS#0 1024. As shown in Table 900, in the case of extension, the starting symbol index of the PDSCH is 6, and its length is 8 symbols. Therefore, slot 1020 illustrates a PDSCH with SIB 1, which starts at symbol index 6 and has a length of 8 symbols.

[0075] Then, the bits sent in the extension (e.g., 8 symbols instead of the original 4 symbols) can be rate-matched output bits of the PDSCH, for example, using rate matching to extend the original information in the PDSCH from 4 bits to 8 bits.

[0076] In other example implementations, instead of extending the length of the PDSCH, PDSCH repeats can be used in conjunction with the PDCCH repeats described above. If PDCCH repeats occur in the same time slot, then PDSCH repeats can occupy the same time slot. Table 900 shows some examples of PDSCH repeat configurations. Specifically, a new set of (S',L') can be added to Table 900, where S' is the starting symbol index of the PDSCH repeat and L' is the length of the PDSCH repeat in symbols. For example, referring to Table 900, row index 7 includes a new set of (S',L') = (8,4) or (10,4), and row index 10 includes a new set of (S',L') = (11,2).

[0077] Figure 11 Example slot diagram 1100 illustrating PDSCH repetition according to various example implementations is shown. See index 7 of Table 900 for description. Figure 11 Examples. Slot 1110 on the left shows the original slot without PDSCH repetition. Slot 1120 on the right shows the applied PDSCH repetition.

[0078] exist Figure 11 In the example, the number of symbols used for the search space of PDCCH is three (3), for example, Therefore, the first three symbols of slot 1110 are the original SS#0 1112. As shown in Table 900, in the absence of PDSCH repetition, the starting symbol index of the PDSCH is 6, and its length is 4 symbols. Therefore, slot 1110 shows a PDSCH with SIB 1, which starts at symbol index 6 and has a length of 4 symbols.

[0079] However, as Figure 9 As shown, for this example, index 7 includes the PDSCH repeating configuration (S',L') = (10,4). Therefore, Figure 11 Slot 1120 shows a PDSCH repeat applied in conjunction with a PDCCH repeat. Therefore, the first three symbols of slot 1120 are the original SS#0 1122, and the next three symbols are a repeat of the PDCCH associated with SS#0 1124. As shown in Table 900, the original PDSCH has a starting symbol index of 6 and a length of 4 symbols. Therefore, slot 1120 shows the original PDSCH 1126 with SIB 1, which starts at symbol index 6 and has a length of 4 symbols. Then, slot 1120 shows the repeating PDSCH 1128 with SIB 1, which starts at symbol index 10 and has a length of 4 symbols.

[0080] Unlike the extension described above, the bits sent in PDSCH repeat 1128 are copies of the bits sent in the original PDSCH.

[0081] PDSCH repeat 1128 may also have a redundant version (RV). In some example embodiments, the RV of PDSCH repeat 1128 may be the same as the RV of the initial PDSCH 1126 as indicated in DCI format 1_0. In other example embodiments, the RV cycle may be applied based on the initial PDSCH 1126 as indicated in DCI format 1_0; for example, if DCI format 1_0 indicates RV=0, then the initial PDSCH 1126 is RV=0, and PDSCH repeat 1128 is RV=3. In still some other example embodiments, the RV of PDSCH repeat 1128 is always 0.

[0082] In other example implementations, PDSCH repetition can be applied to PDCCH repetition in different time slots, for example, in the same manner as the example described above for PDCCH repetition in different time slots.

[0083] Figure 12 Example slot diagram 1200 illustrates PDSCH repetition in a slot later than the original PDSCH, according to various example implementations. See row index 1 of Table 900 for a description. Figure 12 The example shows that the starting symbol index of PDSCH is 3 and the length is 11 symbols.

[0084] exist Figure 12 In the example, the number of symbols used for the PDCCH search space is three (3), for example, Therefore, time slots The first three symbols are the original SS#0 1212. The original PDSCH 1216 is shown as starting at symbol index 3 and in slot 1212. The length is 11 symbols, as configured in row index 1 of Table 900. Slot n11230 shows the associated SS#0 832 used for PDCCH repetition. Slot PDSCH repeat 1236 with the same configuration as in the original time slot is also shown. Time slot diagram 1200 also shows time slot n0+1 1220 and time slot n1+1 1240, which can have similar designs to the corresponding time slots n0 and n1, for example, for SS#0.

[0085] Similar to the examples above, PDSCH repeat 1236 may also have an RV. In some example implementations, the RV of PDSCH repeat 1236 may be the same as the RV of the initial PDSCH 1216 as indicated in DCI format 1_0. In other example implementations, the RV cycle may be applied based on the initial PDSCH 1216 as indicated in DCI format 1_0; for example, if DCI format 1_0 indicates RV=0, then the initial PDSCH 1216 is RV=0, and PDSCH repeat 1236 is RV=3. In still other example implementations, the RV of PDSCH repeat 1236 is always 0.

[0086] Figure 13 An example method 1300 for applying PDCCH / PDSCH repetition to SIB1 is illustrated according to various example implementations. In 1310, the UE may determine the search space set 0 configuration and PDCCH repetition indication. As described above, the MIB may have a field pdcch-ConfigSIB1, which includes a controlreSourceSetZero IE and a SearchSpaceZero IE, the SearchSpaceZero IE having 4 bits for an index indicating the timing of PDCCH monitoring, for example, an index associated with Table 500. The Physical Broadcast Channel (PBCH) physical layer payload indicates whether PDCCH repetition is enabled for Coreset 0; for example, an existing reserved field may be reused to provide this indication.

[0087] In 1320, the UE determines the time slot for PDCCH repetition based on the indicated SearchSpaceZero value. If SearchSpaceZero indicates a single search space set per time slot and PDCCH repetition for coreset 0, the UE can determine that the PDCCH repetition is in the same time slot as the first PDCCH and apply monitoring timing to the PDCCH repetition based on this determination. The start symbol position is predefined, for example, the first symbol after the last symbol of the first PDCCH.

[0088] If SearchSpaceZero indicates two search space sets per slot and PDCCH repetition for coreset 0, the UE can apply different PDCCH monitoring timings in different slots for PDCCH repetitions. The UE can, for example, use the example above where the PDCCH repetition occurs in a later slot (e.g., refer to...). Figure 7 and Figure 8 The equations provided in the described example determine the time slots used to monitor PDCCH repetitions. The start symbol position and duration for PDCCH repetitions are the same as those for the initial PDCCH transmission, for example, as defined in Table 500.

[0089] In step 1330, the UE determines the TDRA for either PDSCH or PDSCH repetition. The determination of the TDRA for either PDSCH or PDSCH repetition can be based on dynamic indications from the network. For example, as described above, the DCI schedules PDSCHs with reserved bits in SIB1 or PBCH. This determination can also depend on PDCCH repetition.

[0090] If a PDCCH repetition is indicated and the PDCCH repetition occurs in the same time slot, the UE can determine whether to apply a TDRA extension for the PDSCH based on the dynamic indication, for example, as defined in Table 900.

[0091] If a PDCCH repetition is indicated and the PDCCH repetition occurs in the same time slot, the UE can determine the TDRA to be applied for the PDSCH repetition based on the dynamic indication, for example, as defined in Table 900.

[0092] If PDCCH repetition is indicated and the PDCCH repetition occurs in different time slots, the UE can determine that PDSCH repetition and PDCCH repetition occur in the same time slot (e.g., as referenced). Figure 12 (as described in the example), and for example, the TDRA for PDSCH repetition is defined in Table 900.

[0093] The following example implementation provides an extension to the PDCCH repetition capability of NTN. As described above, PDCCH can be extended to provide PDCCH repetition in broadcast scenarios, for example, for SIB1. However, the repetition capability extension to NTN described herein can also be applied to dedicated PDCCH scenarios, for example, where the PDCCH is intended for a specific UE or a specific set of UEs.

[0094] In some example implementations, the ntn-PDCCH-Repetition-r19 field in the FeatureSetDownlink-v1900 IE is used to signal to the UE the extension of the PDCCH repetition capability for the NTN.

[0095] In other example implementations, a new UE feature for ntn-PDCCH-repetition can be introduced. This feature supports various configurations for PDCCH repetition. The first example configuration is intra-slot PDCCH repetition based on two associated SS sets linked to the corresponding CORESET, including PDCCH repetition for Type 3 CSS. The second example configuration is the required number of blind detections for two PDCCH candidates. The third example configuration is the maximum amount of overlap per scheduled component carrier per slot when one of the associated PDCCH candidates uses the same set of control channel elements (CCEs) as a separate (unassociated) PDCCH candidate. These configurations allow for UE-specific PDCCH repetition in NTN environments.

[0096] The example implementation described above relates to link-level enhancements for FR1-NTN. The following example implementations, for system-level enhancements for FR1-NTN and / or FR2-NTN, allow for dynamic and flexible power sharing across the entire satellite coverage area between satellite beams or different satellite beam patterns / sizes (e.g., wide or narrow).

[0097] In some example implementations, signaling for the reference signal power is implemented. In current NTN systems, the reference signal transmit power (e.g., SS-PBCH-BlockPower) is configured in the range of (-60, 50) dBm to indicate the average energy per resource cell (EPRE) of the secondary synchronization signal (SSS). Furthermore, the reference signal power control offset (e.g., powercontrolOffsetSS) is configured in the range of (-3, 0, 3, 6) dB to indicate the power offset of the NZP CSI-RS resource cell (RE) relative to the SSB RE; for example, the CSI-RS may have more or less power than the SSS. In some example implementations, the signaling for the reference signal power (e.g., SS-PBCH-BlockPower or powercontrolOffsetSS) can be defined per beam rather than per cell.

[0098] However, due to dynamic power sharing between beams, the transmit power of the SSS and / or NZP CSI-RS can be dynamically increased / decreased. An example implementation allows the network to notify the UE of this change in reference signal power.

[0099] In some example implementations, MAC CE signaling can be used to indicate a dynamic reduction in the transmit power of a reference signal (SSS or NZP CSI-RS). The MAC CE may include the reference signal type (e.g., SSS or NZP CSI-RS), the amount of additional power increase or decrease applied to the SSS or NZP CSI-RS transmit (e.g., X dB) (e.g., X = [0, 6] dB), and the duration of the dynamic reference signal power increase / decrease. If the duration expires, X can be reset to 0. If another MAC CE with a power reduction indication and a value of X' is received before the duration expires, X' replaces X.

[0100] The power increase / decrease to be activated by the UE can be determined based on different options. In the first option, if the MAC CE does not require HARQ-ACK, the UE determines that the power increase / decrease is activated 3ms after receiving the MAC CE. In the second option, if the MAC CE requires HARQ-ACK, the UE determines that the power increase / decrease is activated 3ms after the ACK of the PDSCH carrying the MAC CE.

[0101] Therefore, the additional reference signal transmit power reduction / increase can be used for CSI reporting based on path loss calculations. The path loss calculation for power reduction is based on the reference signal power of (SS-PBCH-BlockPower - X) or (SS-PBCH-BlockPower -powercontrolOffsetSS - X). The increase will be applied in the form of +X.
