Inter-slot repetition of pdcch and pdsch for receipt of SIB 1 for non-terrestrial networks

Abstract

A user equipment (UE) configured for operation in a fifth-generation (5G) new radio (NR) network may monitor type zero (TypeO) physical downlink control channel (PDCCH) common search space (CSS) of search space zero for a downlink control information (DCI) format 1 0. The UE may determine that the DCI format 1 0 is transmitted by a gNB with two inter-slot repetitions comprising a transmission of the DCI format 1 0 in a first slot of the TypeO PDCCH CSS of search space zero and a repetition of the DCI format 1 0 in a second slot of the TypeO PDCCH CSS of search space zero. The UE may determine that repetitions of a physical downlink shared channel (PDSCH) scheduled by the DCI format 1 0 are also to be transmitted with two inter-slot repetitions comprising a transmission of a first repetition of the PDSCH in the first slot of the TypeO PDCCH CSS of search space zero and a repetition of the PDSCH in the second slot of the TypeO PDCCH CSS of search space zero. A first repetition of the PDSCH may be received by the UE in the first slot of the TypeO PDCCH CSS of search space zero and a second repetition of the PDSCH may be received by the UE in the second slot of the TypeO PDCCH CSS of search space zero. The UE may decode at least one of the repetitions of the PDSCH scheduled by the DCI format 1 0 to obtain a system information block 1 (SIB1).

AG4617-PCT 1884.R40WO1INTER-SLOT REPETITION OF PDCCH AND PDSCH FOR RECEIPT OF SIB 1 FOR NON-TERRESTRIAL NETWORKSPRIORITY CLAIM

[0001] This application claims the benefit of priority to United States Provisional Patent Application Serial No. 63 / 736,102, filed December 19, 2024, [reference number AG4617-Z] which is incorporated herein by reference in its entirety.TECHNICAL FIELD

[0002] Embodiments pertain to wireless communications. Some embodiments relate to wireless networks including 3 GPP (Third Generation Partnership Project) and fifth-generation (5G) networks including 5G new radio (NR) (or 5G-NR) networks.BACKGROUND

[0003] Mobile communications have evolved significantly from early voice systems to today’s highly sophisticated integrated communication platform. With the increase in different types of devices communicating with various network devices, usage of 3GPP 5G NR systems has increased. The penetration of mobile devices (user equipment or UEs) in modem society has continued to drive demand for a wide variety of networked devices in many disparate environments. 5G NR wireless systems are forthcoming and are expected to enable even greater speed, connectivity, and usability, and are expected to increase throughput, coverage, and robustness and reduce latency and operational and capital expenditures. 5G-NR networks will continue to evolve based on 3 GPP LTE- Advanced with additional potential new radio access technologies (RATs) to enrich people’s lives with seamless wirelessAG4617-PCT 1884.R40WO1 connectivity solutions delivering fast, rich content and services. As current cellular network frequency is saturated, higher frequencies, such as millimeter wave (mmWave) frequency, can be beneficial due to their high bandwidth.

[0004] For a cellular system, coverage is an important factor for successful operation. Compared to LTE, 5G NR networks can be deployed at relatively higher carrier frequency in frequency range 1 (FR1) (e.g., at 3.5GHz). In this case, coverage loss is expected due to larger path-loss, which makes it more challenging to maintain an adequate quality of service. Typically, uplink coverage is the bottleneck for system operation considering the low transmit power at UE side. Moreover, the 5G NR cellular standard can be used for NonTerrestrial Networks (NTNs), where a UE is served via satellites or High- Altitude Platform Stations. Considering the significant distances between satellite and UE, additional coverage enhancements may be helpful for NTN deployment.BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The following description and the drawings sufficiently illustrate specific embodiments to enable those skilled in the art to practice them. Other embodiments may incorporate structural, logical, electrical, process, and other changes. Portions and features of some embodiments may be included in, or substituted for, those of other embodiments. Embodiments set forth in the claims encompass all available equivalents of those claims.

[0014] Embodiments disclosed herein are directed to a user equipment (UE) configured for operation in a fifth-generation (5G) new radio (NR) network. In these embodiments, the UE may monitor type zero (TypeO) physical downlink control channel (PDCCH) common search space (CSS) of search space zero for a downlink control information (DCI) format 1 0. The UE may determine that the DCI format 1 0 is transmitted by a gNB with two inter-slot repetitions comprising a transmission of the DCI format 1 0 in a first slot of the TypeO PDCCH CSS of search space zero and a repetition of the DCI format 1 0 in a second slot of the TypeO PDCCH CSS of search space zero. The UE may determine that repetitions of a physical downlink shared channel (PDSCH) scheduled by the DCI format 1 0 are also to be transmitted with two inter-slot repetitions comprising a transmission of a first repetition of the PDSCH in the first slot of the TypeO PDCCH CSS of search space zero and a repetition of the PDSCH in the second slot of the TypeO PDCCH CSS of search space zero. A first repetition of the PDSCH may be received by the UE in the first slot of the TypeO PDCCH CSS of search space zero and a second repetition of the PDSCH may be received by the UE in the second slot of the TypeO PDCCH CSS of search space zero. In these embodiments, the UE may decode at least one of the repetitions of the PDSCH scheduled by the DCI format 1 0 to obtain a system information block 1 (SIB1). These embodiments, as well as others, are described in more detail below.AG4617-PCT 1884.R40WO1

[0015] In some embodiments, the UE may assume that the DCI format 1 0 is transmitted with two inter-slot repetitions when the UE is accessing the NR via a non-terrestrial network (NTN). These embodiments, as well as others, are also described in more detail below.

[0016] In some embodiments, the use of the two inter-slot repetitions in the TypeO PDCCH CSS of search space zero for transmission of the DCI format 1 0 as well as for transmission of the PDSCH helps ensure that the UE can receive and properly decode the SIB1, particularly when transmitted from an NTN node, although the scope of the embodiments is not limited in this respect.

[0017] FIG. 1 A illustrates an architecture of a network in accordance with some embodiments. The network 140 A is shown to include user equipment (UE) 101 and UE 102. The UE 101 and UE 102 are illustrated as smartphones (e.g., handheld touchscreen mobile computing devices connectable to one or more cellular networks) but may also include any mobile or non-mobile computing device, such as Personal Data Assistants (PDAs), pagers, laptop computers, desktop computers, wireless handsets, drones, or any other computing device including a wired and / or wireless communications interface. The UE 101 and UE 102 can be collectively referred to herein as UE 101, and UE 101 can be used to perform one or more of the techniques disclosed herein.

[0018] Any of the radio links described herein (e.g., as used in the network 140 A or any other illustrated network) may operate according to any exemplary radio communication technology and / or standard.

[0019] LTE and LTE- Advanced are standards for wireless communications of high-speed data for UE such as mobile telephones. In LTE-Advanced and various wireless systems, carrier aggregation is a technology according to which multiple carrier signals operating on different frequencies may be used to carry communications for a single UE, thus increasing the bandwidth available to a single device. In some embodiments, carrier aggregation may be used where one or more component carriers operate on unlicensed frequencies.

[0020] Embodiments described herein can be used in the context of any spectrum management scheme including, for example, dedicated licensed spectrum, unlicensed spectrum, (licensed) shared spectrum (such as Licensed Shared Access (LSA) in 2.3-2.4 GHz, 3.4-3.6 GHz, 3.6-3.8 GHz, and furtherAG4617-PCT 1884.R40WO1 frequencies and Spectrum Access System (SAS) in 3.55-3.7 GHz and further frequencies).

[0021] Embodiments described herein can also be applied to different Single Carrier or OFDM flavors (CP-OFDM, SC-FDMA, SC-OFDM, filter bank-based multicarrier (FBMC), OFDMA, etc.) and in particular 3 GPP NR (New Radio) by allocating the OFDM carrier data bit vectors to the corresponding symbol resources.

[0022] In some embodiments, any of the UE 101 and UE 102 can comprise an Intemet-of-Things (loT) UE or a Cellular loT (CIoT) UE, which can comprise a network access layer designed for low-power loT applications utilizing short-lived UE connections. In some embodiments, any of the UE 101 and UE 102 can include a narrowband (NB) loT UE (e.g., such as an enhanced NB-IoT (eNB-IoT) UE and Further Enhanced (FeNB-IoT) UE). An loT UE can utilize technologies such as machine-to-machine (M2M) or machine-type communications (MTC) for exchanging data with an MTC server or device via a public land mobile network (PLMN), Proximity -Based Service (ProSe) or device-to-device (D2D) communication, sensor networks, or loT networks. The M2M or MTC exchange of data may be a machine-initiated exchange of data. An loT network includes interconnecting loT UEs, which may include uniquely identifiable embedded computing devices (within the Internet infrastructure), with short-lived connections. The loT UEs may execute background applications (e.g., keep-alive messages, status updates, etc.) to facilitate the connections of the loT network.

[0023] In some embodiments, any of the UE 101 and UE 102 can include enhanced MTC (eMTC) UEs or further enhanced MTC (FeMTC) UEs.

[0024] The UE 101 and UE 102 may be configured to connect, e.g., communicatively couple, with a radio access network (RAN) 110. The RAN 110 may be, for example, an Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN), a NextGen RAN (NG RAN), or some other type of RAN. The UE 101 and UE 102 utilize connections 103 and 104, respectively, each of which comprises a physical communications interface or layer (discussed in further detail below); in this example, the connections 103 and 104 are illustrated as an air interface to enableAG4617-PCT 1884.R40WO1 communicative coupling and can be consistent with cellular communications protocols, such as a Global System for Mobile Communications (GSM) protocol, a code-division multiple access (CDMA) network protocol, a Push-to- Talk (PTT) protocol, a PTT over Cellular (POC) protocol, a Universal Mobile Telecommunications System (UMTS) protocol, a 3GPP Long Term Evolution (LTE) protocol, a fifth-generation (5G) protocol, a New Radio (NR) protocol, and the like.

[0025] In an aspect, the UE 101 and UE 102 may further directly exchange communication data via a ProSe interface 105. The ProSe interface 105 may alternatively be referred to as a sidelink interface comprising one or more logical channels, including but not limited to a Physical Sidelink Control Channel (PSCCH), a Physical Sidelink Shared Channel (PSSCH), a Physical Sidelink Discovery Channel (PSDCH), and a Physical Sidelink Broadcast Channel (PSBCH).

[0026] The UE 102 is shown to be configured to access an access point (AP) 106 via connection 107. The connection 107 can comprise a local wireless connection, such as, for example, a connection consistent with any IEEE 802.11 protocol, according to which the AP 106 can comprise a wireless fidelity (WiFi) router. In this example, the AP 106 is shown to be connected to the Internet without connecting to the core network of the wireless system (described in further detail below).

[0027] The RAN 110 can include one or more access nodes that enable the connections 103 and 104. These access nodes (ANs) can be referred to as base stations (BSs), NodeBs, evolved NodeBs (eNBs), Next Generation NodeBs (gNBs), RAN nodes, and the like, and can comprise ground stations (e.g., terrestrial access points) or satellite stations providing coverage within a geographic area (e.g., a cell). In some embodiments, the RAN nodes 111 and 112 can be transmission / reception points (TRPs). In instances when the RAN nodes 111 and 112 are NodeBs (e.g., eNBs or gNBs), one or more TRPs can function within the communication cell of the NodeBs. The RAN 110 may include one or more RAN nodes for providing macrocells, e.g., macro-RAN node, and one or more RAN nodes for providing femtocells or picocells (e.g.,AG4617-PCT 1884.R40WO1 cells having smaller coverage areas, smaller user capacity, or higher bandwidth compared to macrocells), e.g., low power (LP) RAN node.

[0028] Any of the RAN nodes 111 and 112 can terminate the air interface protocol and can be the first point of contact for the UE 101 and UE 102. In some embodiments, any of the RAN nodes 111 and 112 can fulfill various logical functions for the RAN 110 including, but not limited to, radio network controller (RNC) functions such as radio bearer management, uplink and downlink dynamic radio resource management and data packet scheduling, and mobility management. In an example, any of the RAN nodes 111 and / or 112 can be a new generation Node-B (gNB), an evolved node-B (eNB), or another type of RAN node.

[0029] The RAN 110 is shown to be communicatively coupled to a core network (CN) 120 via an SI interface 113. In embodiments, the CN 120 may be an evolved packet core (EPC) network, a NextGen Packet Core (NPC) network, or some other type of CN. In this aspect, the SI interface 113 is split into two parts: the Sl-U interface 114, which carries traffic data between the RAN nodes 111 and 112 and the serving gateway (S-GW) 122, and the SI -mobility management entity (MME) interface 115, which is a signaling interface between the RAN nodes 111 and 112 and MMEs 121.

[0030] In this aspect, the CN 120 comprises the MMEs 121, the S-GW 122, the Packet Data Network (PDN) Gateway (P-GW) 123, and a home subscriber server (HSS) 124. The MMEs 121 may be similar in function to the control plane of legacy Serving General Packet Radio Service (GPRS) Support Nodes (SGSN). The MMEs 121 may manage mobility embodiments in access such as gateway selection and tracking area list management. The HSS 124 may comprise a database for network users, including subscription-related information to support the network entities handling of communication sessions. The CN 120 may comprise one or several HSSs 124, depending on the number of mobile subscribers, on the capacity of the equipment, on the organization of the network, etc. For example, the HSS 124 can provide support for routing / roaming, authentication, authorization, naming / addressing resolution, location dependencies, etc.AG4617-PCT 1884.R40WO1

[0031] The S-GW 122 may terminate the SI interface 113 towards the RAN 110, and routes data packets between the RAN 110 and the CN 120. In addition, the S-GW 122 may be a local mobility anchor point for inter-RAN node handovers and also may provide an anchor for inter-3 GPP mobility. Other responsibilities of the S-GW 122 may include a lawful intercept, charging, and some policy enforcement.

[0032] The P-GW 123 may terminate an SGi interface toward a PDN. The P-GW 123 may route data packets between the CN 120 and external networks such as a network including the application server 184 (alternatively referred to as application function (AF)) via an Internet Protocol (IP) interface 125. The P-GW 123 can also communicate data to other external networks 131 A, which can include the Internet, IP multimedia subsystem (IPS) network, and other networks. Generally, the application server 184 may be an element offering applications that use IP bearer resources with the core network (e.g., UMTS Packet Services (PS) domain, LTE PS data services, etc.). In this aspect, the P-GW 123 is shown to be communicatively coupled to an application server 184 via an IP interface 125. The application server 184 can also be configured to support one or more communication services (e.g., Voice-over-Internet Protocol (VoIP) sessions, PTT sessions, group communication sessions, social networking services, etc.) for the UE 101 and UE 102 via the CN 120.

[0033] The P-GW 123 may further be a node for policy enforcement and charging data collection. Policy and Charging Rules Function (PCRF) 126 is the policy and charging control element of the CN 120. In a non-roaming scenario, in some embodiments, there may be a single PCRF in the Home Public Land Mobile Network (HPLMN) associated with a UE's Internet Protocol Connectivity Access Network (IP-CAN) session. In a roaming scenario with a local breakout of traffic, there may be two PCRFs associated with a UE's IP- CAN session: a Home PCRF (H-PCRF) within an HPLMN and a Visited PCRF (V-PCRF) within a Visited Public Land Mobile Network (VPLMN). The PCRF 126 may be communicatively coupled to the application server 184 via the P- GW 123.

[0034] In some embodiments, the communication network 140 A can be an loT network or a 5G network, including 5G new radio network usingAG4617-PCT 1884.R40WO1 communications in the licensed (5G NR) and the unlicensed (5G NR-U) spectrum. One of the current enablers of loT is the narrowband-IoT (NB-IoT).

[0035] An NG system architecture can include the RAN 110 and a 5G network core (5GC). In these embodiments, the RAN 110 can include a plurality of nodes, such as gNBs and NG-eNBs. The CN 120 (e.g., a 5G core network or 5GC) can include an access and mobility function (AMF) and / or a user plane function (UPF). The AMF and the UPF can be communicatively coupled to the gNBs and the NG-eNBs via NG interfaces. More specifically, in some embodiments, the gNBs and the NG-eNBs can be connected to the AMF by NG- C interfaces, and to the UPF by NG-U interfaces. The gNBs and the NG-eNBs can be coupled to each other via Xn interfaces.

[0036] In some embodiments, the NG system architecture can use reference points between various nodes as provided by 3GPP Technical Specification (TS) 23.501 (e.g., V15.4.0, 2018-12). In some embodiments, each of the gNBs and the NG-eNBs can be implemented as a base station, a mobile edge server, a small cell, a home eNB, and so forth. In some embodiments, a gNB can be a master node (MN) and NG-eNB can be a secondary node (SN) in a 5G architecture.

[0037] In some embodiments, any of the UEs or base stations described in connection with FIG. 1 can be configured to perform the functionalities described herein. Rel-15 NR systems are designed to operate on the licensed spectrum. The NR-unlicensed (NR-U), a short-hand notation of the NR-based access to unlicensed spectrum, is a technology that enables the operation of NR systems on the unlicensed spectrum.

[0038] FIG. IB illustrates an example of a Non-Terrestrial Network (NTN) in accordance with some embodiments. The NTN 150 provides nonterrestrial NR access to a UE by means of an NTN payload 154 and an NTN Gateway 156, depicting a service link between the NTN payload 154 and a UE, and a feeder link between the NTN Gateway 156 and the NTN payload 154. In these NTN embodiments, the RAN 110 (FIG. 1A) may include NTN node 151, with gNB functionality and which may include the NTN payload 154 and the NTN Gateway 156. The CN 120 (FIG. 1 A) may include an access and mobilityAG4617-PCT 1884.R40WO1 function (AMF) and / or a user plane function (UPF) 150. The AMF and the UPF can be communicatively coupled to the RAN node 111 via NG interfacel52.

[0039] As mentioned above, additional coverage enhancements may be helpful for NTN deployment. For NTNs, the physical downlink shared channel (PDSCH) for carrying system information block 1 (SIB1) and physical downlink control channel (PDCCH) common search space (CSS) (except Type-3 PDCCH CSS) may be bottlenecks for downlink (DL) coverage. In this case, PDSCH repetitions for SIB1 transmission within 20ms may need to be supported to improve the coverage. To enable the repetitions for PDSCH repetitions for SIB1 within 20ms, certain design options are considered.

[0040] Some embodiments disclosed herein provide for transmission of PDSCH SIB1 repetitions for non-terrestrial networks. Some embodiments provide for PDSCH repetitions for SIB1 transmission within 20ms. Some embodiments provide for transmission of both PDCCH repetitions and PDSCH repetitions.

[0041] In accordance with some embodiments, a UE capable of PDSCH repetitions for broadcast channels, which assumed the DCI format 1 0 in the TypeO PDCCH CSS of searchSpaceZero transmitted with two inter-slot repetitions, may assume that PDSCHs scheduled by the DCI format 1 0 have also been transmitted with inter-slot repetitions in the same slots as the TypeO PDCCH CSS, with the same RV as indicated by the DCI format 1 0.

[0042] In some embodiments, one field may be included in the downlink control information (DCI) format 1 0 with Cyclic Redundancy Check (CRC) scrambled by system information - Radio Network Temporary Identifier (SI-RNTI) to indicate that N repetitions are applied for the PDSCH transmission carrying SIB1. In these embodiments, N may be predefined in the specification. In one option, when more than one value of N is defined, the field in the DCI may be used to indicate one value from the more than one value for PDSCH repetitions carrying SIB1 transmission. In another option, if N is fixed in the specification, a single bit field may be included in the reserved bits in DCI format 1 0 with CRC scrambled by SI-RNTI to indicate that the N repetitions are used for PDSCH carrying SIB1 transmission. In one example, N = 2. In particular, bit “1” may be used to indicate that the N repetitions are used forAG4617-PCT 1884.R40WO1PDSCH SIB1 transmission, where bit “0” may be used to indicate that the N repetitions are not used for PDSCH SIB1 transmission.

[0043] In these embodiments, for an indication of the PDSCH repetitions for SIB1 transmission, the following information may be transmitted by means of the DCI format 1 0 with CRC scrambled by SI-RNTI:- Frequency domain resource assignment -|"log2(A°BBWP(A°BBWP+ 1) / 2)"| bits‘BWPis the size of CORESET 0- Time domain resource assignment - 4 bits as defined in Clause 5.1.2.1 of 3GPP TS 38.214.- VRB-to-PRB mapping - 1 bit according to Table 7.3.1.2.2-5 of 3GPP TS 38.212.- Modulation and coding scheme - 5 bits as defined in Clause 5.1.3 of 3GPP TS 38.214, using Table 5.1.3.1-1- Redundancy version - 2 bits as defined in Table 7.3.1.1.1-2 of 3GPP TS 38.212.- System information indicator - 1 bit as defined in Table 7.3.1.2.1-2 of 3GPP TS 38.212.- Repetition indication - 1 bit for the indication of repetition for SIB1 within 20ms- Reserved bits - 16 bits for operation in a cell with shared spectrum channel access in frequency range 1 or for operation in a cell in frequency range 2- 2; otherwise 14 bits.

[0044] In some embodiments, UE is not expected to receive the field to indicate the repetitions for PDSCH SIB1 transmission and system information indicator with bit “1” simultaneously in the DCI format 1 0 with CRC scrambled by SI-RNTI. In another embodiment, one bit in each entry of time domain resource allocation table may be included to indicate that the N repetitions are applied to the PDSCH SIB1. In another option, one state in the modulation and coding scheme (MCS) may be repurposed to indicate that the N repetitions are applied to the PDSCH SIB1.

[0045] In another embodiment, the PDSCH repetition for SIB1 may be transmitted on the available slot, where the available slot is determined as the slot that the PDSCH repetition does not overlap with the UL symbols as indicated by tdd-UL-DL-ConfigurationCommon and / or by tdd-UL- DLC onfigurati onDedi cated .

[0046] Transmission of PDCCH repetitions and PDSCH repetitionsAG4617-PCT 1884.R40WO1

[0047] Embodiments for the transmission of PDCCH repetitions and PDSCH repetitions are provided as follows:

[0048] In some embodiments, in case of PDCCH repetitions for PDCCH CSS, slot offset between PDCCH and PDSCH, i.e., K0 is determined in accordance with the last slot for PDCCH repetitions and the first slot of PDSCH transmission. In some embodiments, the K0 is indicated as part of time domain resource allocation (TDRA) field in the downlink control information (DCI).

[0049] In some embodiments, if repetition is used for the scheduled PDSCH transmission, the slot offset between the PDCCH and PDSCH is determined in accordance with the last slot for PDCCH repetitions and the first slot of PDSCH repetitions.

[0050] In some embodiments, the PDCCH is for PDCCH CSS except Type3 PDCCH CSS, which includes TypeO, TypeOA, TypeOB, Typel, TypelA, Type2 and Type2A PDCCH CSS set. In this case, the PDCCH is for the PDCCH CSS with searchSpaceSIBl, searchSpaceOtherSystemlnformation, pagingSearchSpace, ra-SearchSpace, searchSpaceMCCH, searchSpaceMTCH, pei SearchSpace, and sdt-SearchSpace, respectively. In some embodiments, this may apply to the case when repetition is applied for PDCCH transmission and repetition is not applied for PDSCH transmission. In some other embodiments, this may apply to the case when there is gap between PDCCH and / or PDSCH repetition in time domain.

[0051] FIG. 2 illustrates PDCCH repetitions and a scheduled PDSCH transmission without repetitions, in accordance with some embodiments. In the example, repetition is used for PDCCH transmissions 202 in slot n and n+1, and repetition is not used for PDSCH transmission 204. For this option, K0 = 0 is used to indicate the slot offset between the last slot of PDCCH repetition in slot n+1 and the slot of PDSCH transmission 204 in slot n+1.

[0052] FIG. 3 illustrates an example of PDCCH repetitions and scheduled PDSCH repetitions, in accordance with some embodiments. In this example, repetition is used for PDCCH transmissions 302 in slot n and n+1, and for PDSCH transmission 304 in slot n+1 and n+2. For this option, K0 = 0 is usedAG4617-PCT 1884.R40WO1 to indicate the slot offset between the last slot of PDCCH repetition in slot n+1 and the first slot of PDSCH repetitions in slot n+1.

[0053] In some embodiments, in case of PDCCH repetitions for PDCCH CSS, slot offset between PDCCH and PDSCH, i.e., K0 is determined in accordance with the first slot for PDCCH repetitions and the first slot of PDSCH transmission.

[0054] In another option, in case of PDCCH repetitions for PDCCH CSS and the scheduled PDSCH repetitions, slot offset between PDCCH and PDSCH, i.e., K0 is determined in accordance with the first slot for PDCCH repetitions and the first slot of PDSCH repetitions.

[0055] In some aspect, the PDCCH is for PDCCH CSS except Type3 PDCCH CSS, which includes TypeO, TypeOA, TypeOB, Typel, TypelA, Type2 and Type2A PDCCH CSS set. In this case, the PDCCH is for the PDCCH CSS with searchSpaceSIBl, searchSpaceOtherSy steminformation, pagingSearchSpace, ra-SearchSpace, searchSpaceMCCH, searchSpaceMTCH, pei SearchSpace, and sdt-SearchSpace, respectively.

[0056] In some embodiments, this may apply to the case when repetition is applied for PDCCH transmission and repetition is not applied for PDSCH transmission. In addition, this may apply to the case when repetition is applied for PDCCH transmission and for PDSCH transmission. In some embodiments, this may apply to the case when there is gap between PDCCH and / or PDSCH repetition in time domain.

[0057] FIG. 4 illustrates an example of PDCCH repetitions and a scheduled PDSCH transmission without repetition, in accordance with some embodiments. In the example, repetition is used for PDCCH transmissions 402 in slot n and n+1, and repetition is not used for PDSCH transmission 404. For this option, K0 = 0 is used to indicate the slot offset between the first slot of PDCCH repetition in slot n and the slot of PDSCH transmission 404 in slot n.

[0058] FIG. 5 illustrates an example of PDCCH repetitions and scheduled PDSCH repetitions, in accordance with some embodiments. In the example, repetition is used for PDCCH transmissions 502 in slot n and n+1, and for PDSCH 504 in slot n and n+1. For this option, K0 = 0 is used to indicate theAG4617-PCT 1884.R40WO1 slot offset between the first slot of PDCCH repetition in slot n and the first slot of PDSCH repetitions in slot n.

[0059] In accordance with embodiments, a UE may monitor type zero (TypeO) physical downlink control channel (PDCCH) common search space (CSS) of search space zero for a downlink control information (DCI) format 1 0. The UE may also be configured to determine that the DCI format 1 0 is transmitted by a gNB with two inter-slot repetitions. The two inter-slot repetitions may comprise a transmission of the DCI format 1 0 in a first slot of the TypeO PDCCH CSS of search space zero and a repetition of the DCI format 1 0 in a second slot of the TypeO PDCCH CSS of search space zero. The UE may also be configured to determine that repetitions of a physical downlink shared channel (PDSCH) 504 scheduled by the DCI format 1 0 are also to be transmitted by the gNB with two inter-slot repetitions. The two inter-slot repetitions of the PDSCH 504 may comprise a transmission of a first repetition of the PDSCH 504A in the first slot 503A of the TypeO PDCCH CSS of search space zero and a repetition of the PDSCH 504B in the second slot 503B of the TypeO PDCCH CSS of search space zero. The UE may also be configured to decode the repetitions of the PDSCH 504 scheduled by the DCI format 1 0. In these embodiments, a first repetition of the PDSCH 504A may be received by the UE in the first slot 503A of the TypeO PDCCH CSS of search space zero and a second repetition of the PDSCH 504B may be received by the UE in the second slot 503B of the TypeO PDCCH CSS of search space zero. In these embodiments, the repetitions of the PDSCH 504 scheduled by the DCI format 1 0 may be received in the exact same slots as DCI format 1 0.

[0060] In some embodiments, when the UE assumes that the DCI format 1 0 is transmitted with two inter-slot repetitions, the UE is to assume that the repetitions of the PDSCH 504 scheduled by the DCI format 1 0 are to be transmitted with two inter-slot repetitions.

[0061] In some of these embodiments, the UE may assume repetitions for the TypeO PDCCH CSS of search space zero when indicated in a physical broadcast channel (PBCH). In some embodiments, the indication in the PBCH may comprise an enabling / disabling bit for PDCCH repetition of TypeO-PDCCHAG4617-PCT 1884.R40WO1CSS set of search Space Zero. In these embodiments, the UE may be capable of PDSCH repetitions for broadcast channels.

[0062] In some embodiments, the DCI format 1 0 is carried by a PDCCH transmission 502, In these embodiments, a first repetition of the PDCCH is received in the first slot 503A of the TypeO PDCCH CSS of search space zero and a second repetition of the PDCCH is received in the second slot 503B of the TypeO PDCCH CSS of search space zero. In these embodiments, the repetitions of the PDSCH 504 scheduled by the DCI format 1 0 are received in the exact same slots as repetitions of the PDCCH transmission 502 that carries the DCI format 1 0. In some embodiments, the DCI format 1 0 schedules the repetitions of the PDSCH 504.

[0063] In some embodiments, the UE may be configured to decode at least one of the repetitions of the PDSCH 504 scheduled by the DCI format 1 0 to obtain a system information block 1 (SIB1). In these embodiments, both repetitions of the PDSCH may have the same redundancy version (rv). In other words, both repetitions of the PDSCH may be transmitted by the gNB with the same rv.

[0064] In some embodiments, the DCI format 1 0 with CRC scrambled by SI-RNTI may include a redundancy version, a system information indicator and a repetition indication. In these embodiments, the system information indicator indicates that the SIB1 is carried by the PDSCH 504.

[0065] In some embodiments, the two inter-slot repetitions of the DCI format 1 0 and the two inter-slot repetitions of the PDSCH 504 scheduled by the DCI format 1 0 may be received from a node 151 of a non-terrestrial network (NTN) 150 (see FIG. IB). In some embodiments, the UE assumes that the DCI format 1 0 is transmitted with two inter-slot repetitions when the UE is accessing the NR via the NTN. In these embodiments, the UE is to assume that the repetitions of the PDSCH 504 scheduled by the DCI format 1 0 are to be transmitted with two inter-slot repetitions when the UE assumed that the DCI format 1 0 is transmitted with two inter-slot repetitions. In some embodiments, the UE may refrain from assuming that the DCI format 1 0 is transmitted with two inter-slot repetitions when the UE is accessing the NR via a terrestrial network, although the scope of the embodiments is not limited in this respect. InAG4617-PCT 1884.R40WO1 some embodiments, the node 151 of the NTN 150 may comprise a satellite or an airborne platform. In these embodiments, the node of the NTN may be part or the gNB, although this is not a requirement.

[0066] In some embodiments, for receipt of the SIB1 from the node 151 of the NTN 150, the DCI format 1 0 is transmitted with the two inter-slot repetitions in the TypeO PDCCH CSS of search space zero, and the PDSCH 504 scheduled by the DCI format 1 0 is transmitted with the two inter-slot repetitions in the TypeO PDCCH CSS of search space zero, the PDSCH 504 being transmitted in same slots as the DCI format 1 0.

[0067] In these embodiments, the use of the two inter-slot repetitions in the TypeO PDCCH CSS of search space zero for transmission of the DCI format 1 0 as well as for transmission of the PDSCH 504 helps ensure that the UE can receive and properly decode the SIB1, particularly when transmitted from an NTN node 151.

[0068] In accordance with embodiments, the UE monitors PDCCH candidates in a TypeO-PDCCH CSS set on a primary cell of the MCG configured by pdcch-ConfigSIB 1 in MIB or by searchSpaceSIB 1 in PDCCH- ConfigCommon or by searchSpaceZero in PDCCH-ConfigCommon for a DCI format 1 0 with CRC scrambled by a SI-RNTI. In accordance with embodiments, searchSpaceSIB Us the ID of the search space for SIB1 message. In the initial DL BWP of the UE's PCell, the network sets this field to 0. If the field is absent, the UE does not receive SIB1 in this BWP. In these embodiments, searchSpaceZero may comprise parameters of the common SearchSpace#0. The values are interpreted like the corresponding bits in MIB pdcch-ConfigSIB 1. Even though this field is only configured in the initial BWP (BWP#0), searchSpaceZero can be used in search spaces configured in other DL BWP(s) than the initial DL BWP if the certain conditions are satisfied. In some embodiments, the UE may monitor the TypeO PDCCH CSS of search space zero before receipt of a dedicated RRC configuration.

[0069] FIG. 6 illustrates a procedure for receiving PDCCH and PDSCH repetitions for SIB1 in accordance with some embodiments. In particular, at operation 602, UE may decode a PDCCH with repetitions that schedules a PDSCH SIB1 with repetitions. At operation 604, UE may determine the first slotAG4617-PCT 1884.R40WO1 for the PDSCH SIB1 with repetitions in accordance with the slot offset indication in the PDCCH with repetitions and last slot of the PDCCH repetitions. At operation 606, UE may decode the PDSCH SIB1 with repetitions in accordance with the determined first slot.

[0070] Some embodiments are directed to a user equipment (UE) configured for operation in a fifth-generation (5G) new radio (NR) network. In these embodiments, for receipt of a SIB1 from a non-terrestrial network (NTN), the UE may monitor type zero (TypeO) physical downlink control channel (PDCCH) common search space (CSS) of search space zero for a downlink control information (DCI) format 1 0 and determine that the DCI format 1 0 is transmitted by a gNB with two inter-slot repetitions. The two inter-slot repetitions may comprise a transmission of the DCI format 1 0 in a first slot of the TypeO PDCCH CSS of search space zero and a repetition of the DCI format 1 0 in a second slot of the TypeO PDCCH CSS of search space zero. In these embodiments, the UE may determine that repetitions of a physical downlink shared channel (PDSCH) 504 (FIG. 5) scheduled by the DCI format 1 0 are also to be transmitted by the gNB with two inter-slot repetitions. In these embodiments, the two inter-slot repetitions of the PDSCH 504 comprising transmission of a first repetition of the PDSCH 504A in the first slot 503 A of the TypeO PDCCH CSS of search space zero and a repetition of the PDSCH 504B in the second slot 503B of the TypeO PDCCH CSS of search space zero. In these embodiments, the UE assumes that the DCI format 1 0 is transmitted with two inter-slot repetitions when the UE is accessing the NR via the NTN, and the UE is to assume that the repetitions of the PDSCH 504 scheduled by the DCI format 1 0 are to be transmitted with two inter-slot repetitions when the UE assumed that the DCI format 1 0 is transmitted with two inter-slot repetitions. In some of these embodiments, the UE may refrain from assuming that the DCI format 1 0 is transmitted with two inter-slot repetitions when the UE is accessing the NR via a terrestrial network.

[0071] Some embodiments are directed to a computer-readable storage medium that stores instructions for execution by the processing circuitry of a user equipment (UE) configured for operation in a fifth-generation (5G) new radio (NR) network.AG4617-PCT 1884.R40WO1
