Nested configured grant - small data transfer occasion

Abstract

Various aspects of this disclosure generally relate to wireless communications. In some aspects, a user equipment (UE) can receive from a base station a configuration message indicating a radio resource allocation and transmission scheme for one or more first configuration grant small data transfer (CG-SDT) times and one or more second CG-SDT times. The one or more second CG-SDT times are at least partially nested within one or more first CG-SDT times in terms of time, frequency, or a combination thereof. The UE can therefore use the radio resource allocation and transmission scheme to transmit uplink communications to the base station within one or more first CG-SDT times or one or more second CG-SDT times. Many other aspects are provided.

Description

[0001] Cross-reference to related applications

[0002] This patent application claims priority to U.S. Provisional Patent Application No. 62 / 706,078, filed July 30, 2020, entitled “MULTIPLEXING PRECONFIGUREDUPLINK RESOURECE OSSCAIONS”, and U.S. Non-Provisional Patent Application No. 17 / 443,877, filed July 28, 2021, entitled “NESTING CONFIGURED GRANT-SMALL DATA TRANSFER OCCASIONS”, which are expressly incorporated herein by reference. Technical Field

[0003] Various aspects of this disclosure generally relate to wireless communication, and specifically to techniques and apparatus for authorized small data transmission timing in nested configurations. Background Technology

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunications services such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Access (FDMA) systems, Orthogonal Frequency Division Multiple Access (OFDMA) systems, Single Carrier Frequency Division Multiple Access (SC-FDMA) systems, Time Division Synchronous Code Division Multiple Access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE / LTE-Advanced is a collection of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard issued by the 3rd Generation Partnership Project (3GPP).

[0005] A wireless network may include one or more base stations that support communication between a user equipment (UE) or multiple UEs. A UE may communicate with a base station via downlink and uplink communication. "Downlink" (or "DL") refers to the communication link from the base station to the UE, while "uplink" (or "UL") refers to the communication link from the UE to the base station.

[0006] The aforementioned multiple access technologies have been adopted in various telecommunications standards to provide a common protocol enabling different UEs to communicate at the city, country, region, and / or global levels. New Radio (NR), which can be referred to as 5G, is a collection of enhancements to the LTE mobile standard issued by 3GPP. NR is designed to better support mobile broadband internet access by improving spectrum efficiency, reducing costs, improving service, utilizing new spectrum, and better integrating with other open standards by using Orthogonal Frequency Division Multiplexing (OFDM) with Cyclic Prefix (CP) on the downlink (CP-OFDM), and using CP-OFDM and / or Single Carrier Frequency Division Multiplexing (SC-FDM) (also known as Discrete Fourier Transform Extended OFDM (DFT-s-OFDM)) on the uplink, as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technologies, and carrier aggregation. As the demand for mobile broadband access continues to increase, further improvements to LTE, NR, and other wireless access technologies remain useful. Summary of the Invention

[0036] Various aspects of this disclosure are described more fully below with reference to the accompanying drawings. However, this disclosure may be embodied in many different forms and should not be construed as limited to any particular structure or function given throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of this disclosure to those skilled in the art. Those skilled in the art will understand that the scope of this disclosure is intended to cover any aspect of this disclosure disclosed herein, whether implemented independently of or in combination with any other aspect of this disclosure. For example, any number of aspects set forth herein may be used to implement an apparatus or practice. Furthermore, the scope of this disclosure is intended to cover such apparatus or methods practiced using structures, functions, or structures and functions other than those set forth herein or different from those set forth herein. It should be understood that any aspect of this disclosure disclosed herein may be embodied by one or more elements of the claims.

[0037] Several aspects of a telecommunications system will now be described with reference to various devices and technologies. These devices and technologies will be described in specific implementations below and illustrated in the accompanying drawings through various frames, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as “elements”). These elements can be implemented using hardware, software, or a combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the entire system.

[0038] While the terms commonly associated with 5G or New Radio (NR) Radio Access Technology (RAT) may be used to describe the aspects herein, the aspects of this disclosure can be applied to other RATs, such as 3G RAT, 4G RAT and / or RATs after 5G (e.g., 6G).

[0039] Figure 1This is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be or may include elements of a 5G (e.g., NR) network and / or a 4G (e.g., Long Term Evolution (LTE)) network, as well as other examples. The wireless network 100 may include one or more base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d), user equipment (UE) 120 or multiple UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e), and / or other network entities. Base station 110 is the entity communicating with UE 120. Base station 110 (sometimes referred to as BS) may include, for example, an NR base station, an LTE base station, a Node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, and / or a Transmit / Receive Point (TRP). Each base station 110 may provide communication coverage for a specific geographic area. In the 3rd Generation Partnership Project (3GPP), the term "cell" can refer to the coverage area of ​​base station 110 and / or the base station subsystem serving that coverage area, depending on the context in which the term is used.

[0040] Base station 110 can provide communication coverage for macro cells, pico cells, femtocells, and / or another type of cell. A macro cell can cover a relatively large geographical area (e.g., an area with a radius of several kilometers) and can allow unrestricted access by UE 120 with a service subscription. A pico cell can cover a relatively small geographical area and can allow unrestricted access by UE 120 with a service subscription. A femtocell can cover a relatively small geographical area (e.g., a residential area) and can allow restricted access by UE 120 associated with that femtocell (e.g., UE 120 in a closed subscriber group (CSG)). Base station 110 for macro cells can be referred to as a macro base station. Base station 110 for pico cells can be referred to as a pico base station. Base station 110 for femtocells can be referred to as a femtocell or a home base station. Figure 1 In the example shown, BS 110a can be a macro base station for macro cell 102a, BS 110b can be a pico base station for pico cell 102b, and BS 110c can be a femto base station for femto cell 102c. A base station can support one or more (e.g., three) cells.

[0041] In some examples, the cell may not have to be fixed, and the geographical area of ​​the cell may move depending on the location of the mobile base station 110 (e.g., a mobile base station). In some examples, base station 110 may interconnect with each other and / or interconnect to one or more other base stations 110 or network nodes (not shown) in the wireless network 100 using any suitable transport network via various types of backhaul interfaces such as direct physical connections or virtual networks.

[0042] Wireless network 100 may include one or more relay stations. A relay station is an entity capable of receiving data transmissions from an upstream station (e.g., base station 110 or UE 120) and delivering data transmissions to a downstream station (e.g., UE 120 or base station 110). A relay station may be a UE 120 capable of relaying transmissions to other UEs 120. Figure 1 In the example shown, BS 110d (e.g., a relay base station) can communicate with BS 110a (e.g., a macro base station) and UE 120d to facilitate communication between BS 110a and UE 120d. The base station 110 for relay communication can be referred to as a relay station, relay base station, repeater, etc.

[0043] Wireless network 100 can be a heterogeneous network, comprising different types of base stations 110, such as macro base stations, pico base stations, femto base stations, relay base stations, etc. These different types of base stations 110 can have different transmit power levels, different coverage areas, and / or different effects on interference in wireless network 100. For example, macro base stations can have high transmit power levels (e.g., 5 to 40 watts), while pico base stations, femto base stations, and relay base stations can have lower transmit power levels (e.g., 0.1 to 2 watts).

[0044] Network controller 130 can be coupled to or communicate with a group of base stations 110, and can provide coordination and control over these base stations 110. Network controller 130 can communicate with base stations 110 via backhaul communication links. Base stations 110 can communicate with each other directly or indirectly via wireless or wired backhaul communication links.

[0045] UE 120 may be distributed throughout the wireless network 100, and each UE 120 may be fixed or mobile. UE 120 may include, for example, access terminals, terminals, mobile stations, and / or subscriber units. UE 120 may be a cellular phone (e.g., a smartphone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet device, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smartwatch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or smart bracelet)), an entertainment device (e.g., a music device, a video device, and / or a satellite radio), a vehicle component or sensor, a smart meter / sensor, industrial manufacturing equipment, a GPS device, and / or any other suitable device configured to communicate via a wireless medium.

[0046] Some UEs 120 may be considered Machine-Type Communication (MTC) or Evolved or Enhanced Machine-Type Communication (eMTC) UEs. MTC UEs and / or eMTC UEs may include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags that can communicate with a base station, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (Narrowband IoT) devices. Some UEs 120 may be considered customer premises equipment. UE 120 may be included within a housing that houses the components of UE 120, such as processor components and / or memory components. In some examples, the processor components and memory components may be coupled together. For example, the processor components (e.g., one or more processors) and memory components (e.g., memory) may be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0047] Typically, any number of wireless networks 100 can be deployed in a given geographical area. Each wireless network 100 can support a specific RAT and can operate on one or more frequencies. A RAT can be referred to as a radio technology, air interface, etc. A frequency can be referred to as a carrier, frequency channel, etc. Each frequency can support a single RAT in a given geographical area to avoid interference between wireless networks using different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0048] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more bypass channels (e.g., without using base station 110 as an intermediary for communication with each other). For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, or vehicle-to-pedestrian (V2P) protocols) and / or mesh networks. In such examples, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0049] Devices in Wireless Network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, bands, channels, etc., by frequency or wavelength. For example, devices in Wireless Network 100 can communicate using one or more operating frequency bands. In 5G NR, two initial operating frequency bands have been identified as the frequency range designations FR1 (410MHz-7.125GHz) and FR2 (24.25GHz-52.6GHz). It should be understood that although a portion of FR1 is greater than 6GHz, in various documents and articles, FRi is often (interchangeably) referred to as the “below 6GHz” band. Similar naming issues sometimes occur with FR2, which is often (interchangeably) referred to as the “millimeter wave” band in documents and articles, although it is different from the Extremely High Frequency (EHF) band (30GHz-300GHz) identified as a “millimeter wave” band by the International Telecommunication Union (ITU).

[0050] The frequencies between FR1 and FR2 are generally referred to as intermediate frequency (IF) bands. Recent 5G NR studies have identified the operating bands of these IF bands as the frequency range designation FR3 (7.125GHz-24.25GHz). Bands falling within FR3 can inherit FR1 and / or FR2 characteristics, and thus can effectively extend the features of FR1 and / or FR2 into the IF band. Furthermore, higher frequency bands are currently being explored to extend 5G NR operation above 52.6GHz. For example, three higher operating bands have been identified as the frequency range designations FR4a or FR4-1 (52.6GHz-71GHz), FR4 (52.6GHz-114.25GHz), and FR5 (114.25GHz-300GHz). Each of these higher bands falls within the EHF band.

[0051] Considering the examples above, unless otherwise specifically stated, it should be understood that, as used herein, the terms "below 6 GHz," etc., can broadly refer to frequencies that can be less than 6 GHz, within FR1, or may include intermediate frequency band frequencies. Furthermore, unless otherwise specifically stated, it should be understood that, as used herein, the terms "millimeter wave," etc., can broadly refer to frequencies that can include intermediate frequency band frequencies, within FR2, FR4, FR4-a, or FR4-1 and / or FR5, or within the EHF band. It is contemplated that frequencies included in these operating frequency bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) can be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0052] As indicated above, Figure 1 This is provided as an example. Other examples may differ from the one provided. Figure 1 The example described.

[0053] Figure 2 This is a diagram illustrating an example 200 of communication between a base station 110 and a UE 120 in a wireless network 100 according to the present disclosure. The base station 110 may be equipped with antenna sets 234a to 234t, such as T antennas (T≥1). The UE 120 may be equipped with antenna sets 252a to 252r, such as R antennas (R≥1).

[0054] At base station 110, transmitting processor 220 can receive data from data source 212 intended for UE 120 (or a set of UEs 120). Transmitting processor 220 can select one or more modulation and coding schemes (MCS) for UE 120, at least in part, based on one or more Channel Quality Indicators (CQIs) received from UE 120. UE 120 can process (e.g., encode and modulate) the data for UE 120, at least in part, based on the MCS selected for UE 120, and can provide data symbols for UE 120. Transmitting processor 220 can process system information (e.g., for Semi-Static Resource Partitioning Information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper-layer signaling) and provide overhead symbols and control symbols. Transmitting processor 220 can generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signal (PSS) or secondary synchronization signal (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, where applicable, and can provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems 232 (e.g., T modems), shown as modems 232a to 232t. For example, each output symbol stream can be provided to a modulator component (shown as MOD) of modem 232. Each modem 232 can use a corresponding modulator component to process the corresponding output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modem 232 can further use a corresponding modulator component to process (e.g., convert to analog, amplify, filter, and / or up-convert) the output sample stream to obtain a downlink signal. Modems 232a to 232t can transmit a set of downlink signals (e.g., T downlink signals) via a corresponding set of antennas 234a to 234t, shown as antennas 234a to 234t.

[0055] At UE 120, antenna set 252 (shown as antennas 252a to 252r) can receive downlink signals from base station 110 and / or other base stations 110, and can provide a set of received signals (e.g., R received signals) to modem set 254 (e.g., R modems) shown as modems 254a to 254r. For example, each received signal can be provided to a demodulator component (shown as DEMOD) of modem 254. Each modem 254 can use a corresponding demodulator component to condition (e.g., filter, amplify, downconvert, and / or digitize) the received signal to obtain an input sample. Each modem 254 can use the demodulator component to further process the input sample (e.g., for OFDM) to obtain a received symbol. MIMO detector 256 can obtain the received symbols from modem 254, perform MIMO detection on these received symbols where applicable, and provide the detected symbols. The receiver processor 258 can process (e.g., demodulate and decode) the detected symbols, provide data for decoding of the UE 120 to the data sink 260, and provide control information and system information for decoding to the controller / processor 280. The term "controller / processor" can refer to one or more controllers, one or more processors, or a combination thereof. The channel processor can determine Reference Signal Received Power (RSRP) parameters, Received Signal Strength Indicator (RSSI) parameters, Reference Signal Received Quality (RSRQ) parameters, and / or CQI parameters, among other examples. In some examples, one or more components of the UE 120 may be included in the housing 284.

[0056] Network controller 130 may include communication unit 294, controller / processor 290, and memory 292. Network controller 130 may include one or more devices, such as those in a core network. Network controller 130 may communicate with base station 110 via communication unit 294.

[0057] One or more antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include one or more antenna panels, one or more antenna groups, one or more sets of antenna elements and / or one or more antenna arrays, and other examples, or may be included in one or more antenna panels, one or more antenna groups, one or more sets of antenna elements and / or one or more antenna arrays, and other examples. Antenna panels, antenna groups, sets of antenna elements and / or antenna arrays may include one or more antenna elements (within a single housing or multiple housings), sets of coplanar antenna elements, sets of non-coplanar antenna elements and / or one or more antenna elements coupled to one or more transmitting and / or receiving components, such as... Figure 2 One or more components.

[0058] On the uplink, at UE 120, the transmit processor 264 can receive and process data from data source 262 and control information from controller / processor 280 (e.g., for reporting including RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 264 can generate reference symbols for one or more reference signals. Symbols from the transmit processor 264 can be pre-encoded by the TX MIMO processor 266, where applicable, further processed by the modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to base station 110. In some examples, the modem 254 of UE 120 may include a modulator and demodulator. In some examples, UE 120 includes a transceiver. The transceiver may include any combination of antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, and / or TX MIMO processor 266. The transceiver can be used by a processor (e.g., controller / processor 280) and memory 282 to execute this document (e.g., reference). Figure 4A , Figure 4B , Figure 4C and Figures 5-10 (Aspects of any method described)

[0059] At base station 110, uplink signals from UE 120 and / or other UEs can be received by antenna 234, processed by modem 232 (e.g., a demodulator component of modem 232 shown as DEMOD), detected by MIMO detector 236 where applicable, and further processed by receive processor 238 to obtain decoded data and control information delivered by UE 120. Receive processor 238 can provide the decoded data to data sink 239 and the decoded control information to controller / processor 240. Base station 110 may include communication unit 244 and can communicate with network controller 130 via communication unit 244. Base station 110 may include scheduler 246 to schedule one or more UEs 120 for downlink and / or uplink communication. In some examples, modem 232 of base station 110 may include modulator and demodulator. In some examples, base station 110 includes transceiver. The transceiver may include any combination of antenna 234, modem 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TXMIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to execute this document (e.g., reference). Figure 4A , Figure 4B , Figure 4C and Figures 5-10 (Aspects of any method described)

[0060] The controller / processor 240 of base station 110, the controller / processor 280 of UE 120 and / or Figure 2 Any other component may perform one or more techniques associated with the authorization-small data transfer (CG-SDT) timing of the nested configuration, as described in more detail elsewhere herein. For example, the controller / processor 240 of base station 110, the controller / processor 280 of UE 120, and / or Figure 2 Any other component can execute or direct, for example Figure 7 Process 700 Figure 8 The process 800 Figure 9 The process 900 Figure 10 The operation of process 1000 and / or other processes as described herein. Memory 242 and memory 282 may store data and program code for base station 110 and UE 120, respectively. In some examples, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, one or more instructions, when executed by one or more processors of base station 110 and / or UE 120 (e.g., directly or after compilation, transformation, and / or interpretation), may cause one or more processors, UE 120, and / or base station 110 to perform or direct, for example... Figure 7 Process 700 Figure 8 The process 800 Figure 9 The process 900 Figure 10 The operation of process 1000 and / or other processes as described herein. In some examples, execution instructions may include run instructions, transform instructions, compile instructions and / or interpret instructions, among others.

[0061] In some aspects, the UE (e.g., UE 120) may include: components for receiving from a base station (e.g., base station 110) a configuration message indicating a radio resource allocation and transmission scheme for one or more first CG-SDT times and one or more second CG-SDT times, wherein the one or more second CG-SDT times are at least partially nested within one or more first CG-SDT times; and / or components for transmitting uplink communication to the base station using the radio resource allocation and transmission scheme within one or more first CG-SDT times or one or more second CG-SDT times. Components for the UE to perform the operations described herein may include one or more of, for example, antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, TXMIMO processor 266, controller / processor 280, or memory 282.

[0062] In some aspects, a base station (e.g., base station 110) may include: components for transmitting to a UE (e.g., UE 120) a configuration message indicating a radio resource allocation and transmission scheme for one or more first CG-SDT times and one or more second CG-SDT times, wherein the one or more second CG-SDT times are at least partially nested within one or more first CG-SDT times; and / or components for receiving uplink communication from the UE within one or more first CG-SDT times or one or more second CG-SDT times using the radio resource allocation and transmission scheme. Components for the base station to perform the operations described herein may include one or more of, for example, a transmit processor 220, a TX MIMO processor 230, a modem 232, an antenna 234, a MIMO detector 236, a receive processor 238, a controller / processor 240, a memory 242, or a scheduler 246.

[0063] Nested CG-SDT timing allows UEs to use the same time and / or frequency resources to transmit data to the base station, enabling the base station to allocate fewer time and / or frequency resources to the UE group. Therefore, the base station and UE group reduce network overhead and resource usage by improving the spectral efficiency of CG-SDT transmission.

[0064] In some aspects, the UE (e.g., UE 120) may include: components for receiving from a base station (e.g., base station 110) information indicating radio resource allocation, periodicity, transmission scheme, and resource size for a CG-SDT group including the UE; and / or components for receiving from the base station an index indicating one or more first CG-SDT opportunities, wherein the index is at least partially based on one or more frequency resources included in the one or more first CG-SDT opportunities, one or more time resources included in the one or more first CG-SDT opportunities, and one or more DMRS resources associated with the one or more first CG-SDT opportunities. Components for the UE to perform the operations described herein may include one or more of, for example, antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, TXMIMO processor 266, controller / processor 280, or memory 282.

[0065] In some aspects, a base station (e.g., base station 110) may include: components for transmitting to a UE (e.g., UE 120) information indicating radio resource allocation, periodicity, transmission scheme, and resource size for a CG-SDT group including the UE; and / or components for transmitting to the UE an index indicating one or more first CG-SDT opportunities, wherein the index is at least partially based on one or more frequency resources included in the one or more first CG-SDT opportunities, one or more time resources included in the one or more first CG-SDT opportunities, and one or more DMRS resources associated with the one or more first CG-SDT opportunities. Components for the base station to perform the operations described herein may include one or more of, for example, a transmit processor 220, a TXMIMO processor 230, a modem 232, an antenna 234, a MIMO detector 236, a receive processor 238, a controller / processor 240, a memory 242, or a scheduler 246.

[0066] Indexing CG-SDT timings based on frequency, time, and / or DMRS resources allows the base station to identify one of the CG-SGT timings using a single index, enabling the base station to allocate CG-SDT timings to UE groups with less transmission. Therefore, signaling overhead is reduced for both the base station and the UE group, and memory is saved.

[0067] Although Figure 2 The boxes in the diagram represent different components, but the functions described above with respect to the boxes can be implemented in a single hardware, software, or combined component, or in various combinations of components. For example, the functions described with respect to the transmit processor 264, receive processor 258, and / or TX MIMO processor 266 can be performed by the controller / processor 280 or under the control of the controller / processor 280.

[0068] As indicated above, Figure 2 This is provided as an example. Other examples may differ from the one provided. Figure 2 The example described.

[0069] Figure 3A This is a diagram illustrating example 300 of multiplexing uplink transmissions using various multiplexing modes according to this disclosure. For example, Figure 3A Various symbols are shown for uplink transmissions from a UE (e.g., UE 120), and various ways in which UE 120 can multiplex multiple uplink transmissions in various symbols. Figure 3A The striped pattern frames shown (e.g., 302a, 302b, 302c, 302d, 302e, 302f, 302g, 302h, 302i, 302j, and 302k) illustrate resource elements including data related to the sounding reference signal (SRS), and Figure 3A The black boxes shown (e.g., 304a, 304b, and 304c) indicate resource elements that include data related to DMRS. Additionally, Figure 3A The cross-shaded boxes shown (e.g., 306a, 306b, 306c, 306d, 306e, 306f, and 306g) indicate resource elements that include data related to uplink communication (e.g., Physical Uplink Shared Channel (PUSCH) communication), and Figure 3A The white boxes 308a, 308b, 308c and 308d shown indicate empty resource elements, resource elements containing other types of data and / or other types of resource elements.

[0070] As shown by reference numeral 310 in the attached figure, UE 120 may multiplex SRS and DMRS in DMRS-related symbols (e.g., SRS may be multiplexed with the preceding DMRS). For example, UE 120 may multiplex SRS and DMRS by using frequency domain multiplexing (FDM). In some aspects, using FDM may include transmitting SRS and DMRS on different resource block sets and / or transmitting SRS and DMRS on different frequency combs in the same resource block set (e.g., even frequency modulations for DMRS and odd frequency modulations for SRS, or even frequency modulations for SRS and odd frequency modulations for DMRS). Therefore, DMRS resource elements 304a, 304b, and 304c are separated from SRS resource elements 302a, 302b, 302c, and 302d. In some aspects, when operating in a first multiplexing mode, UE 120 may multiplex SRS as described above.

[0071] Additionally or alternatively, and as indicated by reference numeral 320, UE 120 may multiplex SRS and PUSCH communications. For example, UE 120 may multiplex SRS and PUSCH communications using FDM. As described above, using FDM may include transmitting SRS and PUSCH communications on different resource block sets and / or transmitting SRS and PUSCH communications on different frequency combs within the same resource block set (e.g., even-numbered frequency bands for PUSCH and odd-numbered frequency bands for SRS, or even-numbered frequency bands for SRS and odd-numbered frequency bands for PUSCH). Thus, PUSCH resource elements 306a, 306b, and 306c are separated from SRS resource elements 302e, 302f, 302g, and 302h. In some aspects, when operating in a second multiplexing mode, UE 120 may multiplex SRS as described above.

[0072] In some respects, UE 120 can access resource elements occupied by SRS (e.g., such as...) Figure 3ARate matching is performed on PUSCH communications around the subcarriers shown. In one example of rate matching, when the SRS occupies a subset of frequency moduli on an OFDM symbol, such as frequency moduli indices 0, 4, 8, etc. within each resource block, the UE 120 can map PUSCH communications to other frequency moduli in each resource block on the same OFDM symbol, such as mapping to frequency moduli indices 1, 2, 3, 5, 6, 7, 9, 10, 11, etc.

[0073] Additionally or alternatively, and as indicated by reference numeral 330 in the accompanying drawings, UE 120 may multiplex the SRS using spatial domain multiplexing (SDM). For example, SDM can allow multiple channels to overlap and allow different communications to be transmitted on the same resource element. In some aspects, UE 120 may multiplex the SRS such that the SRS partially overlaps with symbols including PUSCH communications, and the SRS and PUSCH communications can use the same resource element (e.g., as shown in Figure 330). Figure 3A (The subcarriers shown). Therefore, PUSCH resource elements 306d and 306f are separated from SRS resource elements (e.g., SRS resource element 302i), but PUSCH resource elements 306e and 306g overlap with SRS resource elements 302j and 302k. In some respects, when operating in the third multiplexing mode, UE 120 can multiplex the SRS as described above.

[0074] As indicated above, Figure 3A This is provided as an example. Other examples are possible and may differ from those provided. Figure 3A The example described.

[0075] Figure 3B This is a diagram illustrating Example 340 of an uplink transmission scheme according to the present disclosure. In some aspects, Example 340 can be configured for multi-cluster SC-FDMA transmission, etc. In Example 340, the channel bandwidth 350 is shown as 20 MHz (e.g., for LTE unlicensed (LTE-U)). Although the description herein focuses on 20 MHz, the description similarly applies to other bandwidths. Typically, the actual channel bandwidth 360 can be a subset of the channel bandwidth 350. In Example 340, the actual channel bandwidth 360 is shown as 100 resource blocks (RBs), which can be approximately 18 MHz. Although the description herein focuses on 100 RBs, the description similarly applies to other resource block allocations.

[0076] For an uplink transmission to be considered occupied channel bandwidth, it must span at least 80% of channel bandwidth 350. Therefore, in Example 340, the occupied channel bandwidth 370 is illustrated as 91 RBs, which can be approximately 16.4 MHz. Although this description focuses on 91 RBs, the description similarly applies to other resource block occupancy. In some aspects, for uplink transmissions such as PUSCH transmissions, 10 PUSCH channels can be multiplexed with a minimum interleaving granularity of 10 RBs to meet the occupied bandwidth requirement. Although this description focuses on 10 PUSCH channels with a minimum interleaving granularity of 10 RBs, the description similarly applies to other numbers of PUSCH channels and / or other minimum interleaving granularities. In Example 340, interleaving 1 to interleaving 10, including uplink transmission RBs 380 and 390 spanning the occupied channel bandwidth 370, meet the occupied bandwidth requirement for unlicensed spectrum in LTE-U deployments.

[0077] In some aspects, uplink signals such as the Physical Uplink Control Channel (PUCCH) and / or PUSCH signals, as well as other examples, can be based on a Local Frequency Division Multiplexing (LFDM) waveform occupying a set of subcarriers. Therefore, UE 120 can transmit different modulation symbols and / or perform at least some precoding for each subcarrier before delivering the frequency domain waveform.

[0078] As indicated above, Figure 3B This is provided as an example. Other examples are possible and may differ from those provided. Figure 3B The example described.

[0079] Some UEs can operate with fewer antennas (e.g., fewer Rx antennas) and / or reduced bandwidth (e.g., operating in the 5MHz-20MHz range instead of a 100MHz bandwidth) to conserve battery power. Such UEs can include smart devices (such as smartwatches and / or fitness trackers, and other examples), industrial sensors and / or video surveillance equipment, and other examples, and can be referred to as reduced-capacity UEs (“RedCap UEs”) or “NR-light UEs”.

[0080] To conserve battery power for RedCap UEs, base stations can provide CG-SDT timings, during which the RedCap UE can communicate with the base station even when it is in idle mode or inactive. As used herein, CG-SDT timings can also be referred to as Pre-Configured Uplink Resource (PUR) timings. For example, the 3GPP specification for 5G uses the term CG-SDT, while the 3GPP specification for LTE uses the term PUR.

[0081] Existing 3GPP specifications and / or other standards for PUR configuration are limited. For example, 3GPP specifications do not allow PUR opportunities to be shared by more than two UEs. Additionally, 3GPP specifications require UEs sharing PUR opportunities to use orthogonal DMRS with different cyclic shifts. Therefore, when configuring multiple UEs with PUR opportunities, the base station can use a large amount of spectrum.

[0082] The techniques and apparatus described herein allow a base station (e.g., base station 110) to configure a UE group (e.g., including UE 120) for one or more nested CG-SDT timings in time and / or frequency. A first CG-SDT timing may be associated with a set of time resources and a set of frequency resources, such that a second CG-SDT timing can be “nested” within the first CG-SDT timing by being associated with at least a subset of the set of time resources and / or a subset of the set of frequency resources. Nested CG-SDT timings allow UEs to use the same time resources and / or frequency resources to transmit data to base station 110, allowing base station 110 to allocate fewer time resources and / or frequency resources to the UE group. Therefore, base station 110 and the UE group reduce network overhead and resource usage by improving the spectral efficiency of CG-SDT transmission. As a result, network congestion is reduced, saving power at base station 110 and the UE group by reducing failed reception, failed decoding, and retransmissions.

[0083] Additionally or alternatively, the techniques and apparatus described herein allow base station 110 and the UE group to apply sequencing rules to multiple CG-SDT timings. Therefore, base station 110 reduces the signaling overhead used to configure CG-SDT timings, saving power and processing resources at both base station 110 and the UE group. Furthermore, as a result, network congestion is reduced, saving power at both base station 110 and the UE group by reducing failed reception, failed decoding, and retransmissions.

[0084] Figure 4A , Figure 4B and Figure 4C These are illustrations of examples 400, 410, and 420, respectively, relating to the timing of nested CG-SDT, according to this disclosure. Figures 4A-4CAs shown, Examples 400, 410, and 420 all include a first resource set and a second resource set for CG-SDT timing. A group of UEs (e.g., including UE 120 and one or more other UEs) can use the CG-SDT timing for uplink transmissions to a base station (e.g., base station 110). For example, uplink transmissions may include PUSCH transmissions. The UE group can share CG-SDT timing and can be distinguished by corresponding DMRS port indices associated with the corresponding UEs. In some aspects, base station 110 and the UE group can be included in a wireless network such as wireless network 100.

[0085] In Examples 400, 410, and 420, base station 110 may send a configuration message indicating one or more first CG-SDT timings and one or more second CG-SDT timings, and UE 120 may receive the configuration message. Figure 4A As shown, the CG-SDT resource 405 for the second CG-SDT timing is at least partially nested within the CG-SDT resource 401 for the first CG-SDT timing. The start of the CG-SDT resource 405 is not time-offset with the start of the CG-SDT resource 401, but is depicted with a stereo offset to show the nesting.

[0086] A first CG-SDT timing can be associated with a set of time resources and a set of frequency resources, such that a second CG-SDT timing can be "partially nested" within the first CG-SDT timing by being associated with at least a subset of time resources comprising the set of time resources and / or at least a subset of frequency resources comprising the set of frequency resources. Therefore, CG-SDT resource 405 is frequency-nested within CG-SDT resource 401 because CG-SDT resource 405 includes a subset of the frequency resources included in CG-SDT resource 401. In some aspects, CG-SDT resource 405 may additionally include one or more frequency resources not included in CG-SDT resource 405 but still partially nested. Similarly, CG-SDT resource 405 is time-nested within CG-SDT resource 401 because CG-SDT resource 405 includes the time resources included in CG-SDT resource 401. In some aspects, CG-SDT resource 405 may additionally include one or more time resources not included in CG-SDT resource 405 but still partially nested.

[0087] Similarly, such as Figure 4B As shown, CG-SDT resources 415a and 415b for the second CG-SDT timing are at least partially nested within CG-SDT resource 411 for the first CG-SDT timing. Similarly, as Figure 4CAs shown, CG-SDT resources 425a and 425b for the second CG-SDT timing are at least partially nested within CG-SDT resource 421 for the first CG-SDT timing.

[0088] Therefore, UE 120 can transmit uplink communication (e.g., PUSCH transmission) during either the first CG-SDT or the second CG-SDT, and base station 110 can receive uplink communication (e.g., PUSCH transmission) during either the first CG-SDT or the second CG-SDT. For example, base station 110 can configure UE 120 to use either the first CG-SDT or the second CG-SDT. Therefore, base station 110 can distinguish between the first uplink communication in the first CG-SDT and the second uplink communication in the second CG-SDT, at least in part, based on the different DMRS resources associated with the first uplink communication compared to the second uplink communication (e.g., associated with different antenna port indices and / or different DMRS indices).

[0089] In some respects, the first CG-SDT timing and the second CG-SDT timing can be associated with the same CG-SDT group including UE 120. For example, base station 110 can configure the UE group together, allocating the first CG-SDT timing to at least some of the UEs in the UE group and allocating the second CG-SDT timing to the other UEs in the UE group. By allocating the UE group together, base station 110 reduces signaling overhead because base station 110 can broadcast or multicast the allocation instead of allocating CG-SDT timing to individual UEs.

[0090] In some aspects, such as Figures 4A-4CAs shown, the second CG-SDT timing can be associated with a resource size different from the resource size associated with the first CG-SDT timing. In Example 400, CG-SDT resource 405 for the second CG-SDT timing includes 6 RBs, and CG-SDT resource 401 for the first CG-SDT timing includes 12 RBs. Similarly, in Example 410, CG-SDT resources 415a and 415b for the second CG-SDT timing include 6 RBs, and CG-SDT resource 411 for the first CG-SDT timing includes 12 RBs. Similarly, in Example 420, CG-SDT resources 425a and 425b for the second CG-SDT timing include 6 RBs, and CG-SDT resource 421 for the first CG-SDT timing includes 12 RBs. Other examples may include larger second CG-SDT timings (e.g., 7 RBs, 8 RBs, 9 RBs, etc.) or smaller second CG-SDT timings (e.g., 1 RB, 2 RBs, 3 RBs, 4 RBs, or 5 RBs). Additionally or alternatively, other examples include larger first CG-SDT timings (e.g., 14 RBs, 15 RBs, 16 RBs, etc.) or smaller first CG-SDT timings (e.g., 1 RB, 2 RBs, 3 RBs, etc.). By assigning some UEs within the group to first CG-SDT timings and the remaining UEs in the group to second CG-SDT timings, base station 110 is able to allocate smaller CG-SDT resources (e.g., CG-SDT resources 405, 415a, and 415b or 425a and 425b) to UEs expected to have less uplink communication, and larger CG-SDT resources (e.g., CG-SDT resources 401, 411, or 421, respectively) to UEs expected to have greater uplink communication. Therefore, base station 110 reduces the waiting time for UEs expected to have large uplink communication, while saving network spectrum allocated to UEs expected to have small uplink communication.

[0091] To avoid interference, base station 110 can utilize orthogonal (or at least quasi-orthogonal) multiplexing in one or more dimensions to configure the first CG-SDT timing and the second CG-SDT timing. For example, as described below, base station 110 can associate a first DMRS resource with a first CG-SDT timing, the first CG-SDT timing being orthogonal to a second DMRS resource associated with a second CG-SDT timing. In another example, as described below, base station 110 can associate a first beam with a first CG-SDT timing, the first CG-SDT timing being orthogonal to a second beam associated with a second CG-SDT timing. As shown in Examples 400, 410, and 420, one or more second CG-SDT timings are at least partially nested within a first CG-SDT timing in time. Therefore, as further illustrated in Examples 400, 410, and 420, the DMRS resources associated with the second CG-SDT timing (e.g., DMRS resources 407 in Example 400, DMRS resources 417a and 417b in Example 410, and DMRS resources 427a and 427b in Example 420) can be orthogonal (or at least quasi-orthogonal) to the DMRS resources associated with the first CG-SDT timing (e.g., DMRS resources 403 in Example 400, DMRS resources 413 in Example 410, and DMRS resources 423 in Example 420). For example, in Example 400, DMRS resources 417a and 417b can be associated with different cyclic shifts, different beams, and / or other different physical properties, such that DMRS resources 417a and 417b are orthogonal even if they overlap in time and frequency. Additionally or alternatively, one or more first CG-SDT timings may occupy frequencies different from those occupied by one or more second CG-SDT timings. Thus, the second CG-SDT timings may be at least partially nested with the first CG-SDT timings in time, but orthogonal in frequency.

[0092] As further illustrated in Examples 400, 410, and 420, one or more second CG-SDT timings are at least partially nested within a first CG-SDT timing in frequency. Therefore, as further illustrated in Examples 400, 410, and 420, the DMRS resources associated with the second CG-SDT timings (e.g., DMRS resources 407 in Example 400, 417a and 417b in Example 410, and 427a and 427b in Example 420) may be orthogonal (or at least quasi-orthogonal) to the DMRS resources associated with the first CG-SDT timings (e.g., DMRS resources 403 in Example 400, 413 in Example 410, and 423 in Example 420). Additionally or alternatively, one or more first CG-SDT timings may occupy a different time domain portion than the time domain portion occupied by one or more second CG-SDT timings. Therefore, the second CG-SDT timing can be at least partially nested with the first CG-SDT timing in frequency, but orthogonal in time.

[0093] Other examples may differ from those shown in Examples 400, 410, and 420. For example, one or more second CG-SDT timings may additionally or alternatively be spatially at least partially nested within a first CG-SDT timing. For example, a second CG-SDT timing may be associated with one or more beams that are included within a beam set associated with a first CG-SDT timing. Thus, DMRS resources associated with a second CG-SDT timing (e.g., DMRS resource 407 in Example 400, DMRS resources 417a and 417b in Example 410, and DMRS resources 427a and 427b in Example 420) may be at least partially shared with DMRS resources associated with a first CG-SDT timing (e.g., DMRS resource 403 in Example 400, DMRS resource 413 in Example 410, and DMRS resource 423 in Example 420). Furthermore, to avoid interference, one or more first CG-SDT timings may occupy different frequencies and / or different portions of the time domain than one or more second CG-SDT timings. For example, a second CG-SDT timing may be at least partially nested with a first CG-SDT timing in time, but separated in frequency to reduce interference. Alternatively, a second CG-SDT timing may be at least partially nested with a first CG-SDT timing in frequency, but separated in time to reduce interference.

[0094] like Figure 4BAs further illustrated in Example 410, base station 110 may indicate one or more mapping or repetition schemes in the time domain for the PUSCH used by UE 120 to transmit uplink communications therein. Additionally or alternatively, base station 110 may indicate MCS and / or frequency hopping for the PUSCH used by UE 120 to transmit uplink communications therein. Figure 4C Example 420 depicts an example of frequency hopping for a second CG-SDT timing. Additionally or alternatively, the first CG-SDT timing may include frequency hopping. For example, the first CG-SDT timing in Example 400 may include an additional set of CG-SDT resources that are temporally separated and frequency-shifted compared to CG-SDT resource 401. Therefore, the CG-SDT resources for the second CG-SDT timing may be nested only within CG-SDT resource 401, only within the additional set of CG-SDT resources, or both.

[0095] Such as combination Figure 6 In further detail, base station 110 can use indexes to allocate CG-SDT opportunities. For example, an index can identify different sets of CG-SDT opportunities that have the same resource size but are located in different parts of the frequency, time, and / or spatial domains. In some aspects, the index can be at least partially based on one or more frequency resources included in one or more CG-SDT opportunities (e.g., indicated by one or more frequency resource indices, where each index can be defined by f...). id (represented by) one or more time resources included in the CG-SDT timing (e.g., indicated by one or more time resource indices, where each index can be represented by t). id (representation), and one or more DMRS resources associated with the CG-SDT timing (e.g., indicated by one or more DMRS resource indexes, where each index can be represented by DMRS). id (This is a representation of the index). Therefore, the index can be based at least in part on ascending order of frequency resources, ascending order of time resources, and ascending order of DMRS resources, but rather sequentially. For example, the index can increase sequentially as different CG-SDT timing sets increase in frequency (but not in time or DMRS), then it can further increase sequentially as different CG-SDT timing sets increase in DMRS (but not in time), and finally sequentially as different CG-SDT timing sets increase in time. Other examples can modify the sequential increase order (e.g., time first, frequency second, and DMRS third; time first, DMRS second, and frequency third; frequency first, time second, and DMRS third; DMRS first, time second, and frequency third; and / or DMRS first, frequency second, and time third). In one example, the first CG-SDT timing can be associated with frequency resource index 0 (e.g., f).id =0), DMRS resource index 0 (e.g., DMRS idd =0) and time resource index 1 (e.g., t id =1) is associated with it. Similarly, the second CG-SDT timing can be associated with frequency resource index 1 (e.g., f id =1), DMRS resource index 1 (e.g., DMRS) id =1) and time resource index 1 (e.g., t) id =1) is associated, and the third CG-SDT timing can be associated with frequency resource index 1 (e.g., f id =1), DMRS resource index 0 (e.g., DMRS) idd =0) and time resource index 1 (e.g., t id =1) is associated. The fourth CG-SDT timing can be associated with frequency resource index 1 (e.g., f id =1), DMRS resource index 1 (e.g., DMRS) id =1) and time resource index 0 (e.g., t) id =0) associated. Therefore, the CG-SDT index can be assigned as follows: the first index (e.g., zero) is assigned to the first CG-SDT opportunity because the frequency resource index is zero and the remaining CG-SDT opportunity is associated with frequency resource index 1; the second index (e.g., 1) is assigned to the third CG-SDT opportunity because the DMRS resource index is zero and the remaining CG-SDT opportunity is associated with DMRS resource index 1; the third index (e.g., 2) is assigned to the fourth CG-SDT opportunity because the time resource index is zero and the remaining CG-SDT opportunity is associated with time resource index 1; and the last index (e.g., 3) is assigned to the remaining second CG-SDT opportunity.

[0096] The index may be based, at least in part, on one or more rules stored by base station 110 (e.g., programmed into base station 110 and / or otherwise pre-configured for base station 110) and / or on one or more rules stored by UE 120 (e.g., programmed into UE 120 and / or otherwise pre-configured for UE 120), but sequentially. For example, the stored rules may be based on 3GPP specifications and / or another standard. Additionally or alternatively, the index may be based, at least in part, on one or more rules indicated by base station 110 to UE 120, but sequentially. For example, base station 110 may perform Radio Resource Control (RRC) configuration on UE 120 to select from multiple stored rules. Alternatively, base station 110 may perform RRC configuration on UE 120 against rules without using stored rules.

[0097] By using combination Figures 4A-4CThe nested arrangement described improves the spectral efficiency of CG-SDT transmission between base station 110 and UE 120. Base station 110 can allocate groups of UEs together to different nested CG-SDT opportunities to reduce signaling overhead, as it can broadcast or multicast the allocation instead of allocating CG-SDT opportunities to individual UEs. Therefore, base station 110 and UE 120 reduce network overhead and resource consumption. Additionally, in some aspects, base station 110 can allocate some UEs within the group to smaller CG-SDT resources (e.g., to UEs expected to have less uplink communication) and allocate other UEs to larger CG-SDT resources (e.g., to UEs expected to have more uplink communication), reducing latency for UEs expected to have more uplink communication while conserving network spectrum allocated to UEs expected to have less uplink communication.

[0098] Additionally or alternatively, by using, for example, a combination Figures 4A-4C The described index reduces the signaling overhead for configuring CG-SDT timing for both base station 110 and UE 120. Base station 110 can identify CG-SDT timing using a single index (e.g., at least partially based on a frequency resource index, a time resource index, and / or a DMRS resource index), allowing base station 110 to send less information when allocating CG-SDT timing to UE 120. Therefore, base station 110 and UE 120 reduce network overhead and resource consumption.

[0099] As indicated above, Figures 4A-4C This is provided as an example. Other examples may differ from the one provided. Figures 4A-4C The example described.

[0100] Figure 5 This is a diagram illustrating an example 500 associated with a transmission chain for uplink transmission according to this disclosure. Figure 5 As shown, Example 500 illustrates a process for a UE (e.g., UE 120) to deliver uplink transmissions (e.g., PUSCH communication). For example, UE 120 may deliver uplink transmissions to a base station (e.g., base station 110). In some aspects, UE 120 may deliver uplink transmissions at CG-SDT timing (e.g., by base station 110, as in conjunction with...). Figure 4A Uplink transmissions are delivered in the configuration described in Figure 4C. In some respects, base station 110 and UE 120 may be included in a wireless network such as wireless network 100.

[0101] like Figure 5As shown, UE 120 can schedule transport block (TB) 501 for uplink transmission within the CG-SDT timing. UE 120 can encode TB 501 according to the channel used for the CG-SDT timing (box 503). In some aspects, UE 120 can additionally rate match TB 501 (box 503) (e.g., to avoid interference on the channel).

[0102] like Figure 5 As further shown, UE 120 can scramble the identifier of uplink transmissions (box 505). The scrambling identifier allows base station 110 to separate uplink transmissions delivered by UE 120 from other signals received from other UEs. In some aspects, UE 120 can scramble the identifier of uplink transmissions at least in part based on an index associated with the CG-SDT timing selected by UE 120 for the uplink transmission. Using the CG-SDT index allows base station 110 to separate uplink transmissions associated with one CG-SDT timing from uplink transmissions associated with another CG-SDT timing (e.g., nested or partially nested CG-SDT timings). In some aspects, the index may include or otherwise be at least in part based on, for example, a combination of... Figures 4A-4C The index described. Additionally or alternatively, such as... Figure 5 As further shown, UE 120 may scramble the identifier of the uplink transmission based at least in part on an index associated with DMRS 509 related to the CG-SDT timing. Using the DMRS index allows base station 110 to separate an uplink transmission from one UE in the CG-SDT group from another uplink transmission from another UE in the same CG-SDT group. Additionally or alternatively, UE 120 may scramble the identifier of the uplink transmission based at least in part on the identifier of the cell in which UE 120 is transmitting, the identifier of UE 120, and / or another identifier.

[0103] like Figure 5 As further shown, UE 120 can perform linear modulation (box 511), transform precoding (box 513), and / or inverse fast Fourier transform (IFFT) (box 515) on uplink transmissions including scrambling identifiers. As an addition or alternative to scrambling the identifiers of uplink transmissions using an index associated with DMRS 509, UE 120 can multiplex DMRS 509 with the IFFT-processed uplink transmission (MUX) (box 517).

[0104] like Figure 5 As further shown in the diagram, UE 120 can map multiplexed uplink transmissions to one or more radio resources for transmission during CG-SDT timing (Box 519). Figure 5 As indicated by reference numeral 507 in the accompanying drawings, mapping and DMRS 509 may have already been configured by base station 110 (e.g., using RRC signaling). For example, base station 110 may configure mapping and DMRS 509 when configuring CG-SDT timing. Therefore, UE 120 may generate signal 521 that encodes uplink transmissions for transmission during CG-SDT timing.

[0105] By using combination Figure 5 The described transmission chain allows UE 120 to associate uplink transmissions with an index of the CG-SDT timing selected by UE 120 for the uplink transmission. Therefore, UE 120 can use a combination of... Figures 4A-4C The described index allows base station 110 to distinguish uplink transmissions from UE 120 from other signals without having to send additional information (e.g., temporary identifiers, such as RNTI) to UE 120. Alternatively or additionally, UE 120 may associate uplink transmissions with an index of the DMRS configured by base station 110 for uplink transmissions. Therefore, UE 120 can use the DMRS index to allow base station 110 to distinguish uplink transmissions from UE 120 from other signals without having to send additional information (e.g., temporary identifiers, such as RNTI) to UE 120.

[0106] As indicated above, Figure 5 This is provided as an example. Other examples may differ from the one provided. Figure 5 The example described.

[0107] Figure 6 This is a diagram illustrating an example 600 associated with the timing of using CG-SDT for uplink transmission according to this disclosure. Figure 6 As shown, Example 600 includes communication between base station 110 and UE 120. In some aspects, base station 110 and UE 120 may be included in a wireless network such as wireless network 100. Base station 110 and UE 120 may communicate on a radio access link, which may include an uplink and a downlink. In performing the combination... Figure 6 While the operation described is in progress, UE 120 can be in inactive mode, idle state, or connected mode.

[0108] As shown in conjunction with reference to reference numeral 605, base station 110 may transmit a configuration message indicating a radio resource allocation and transmission scheme for one or more first CG-SDT opportunities and one or more second CG-SDT opportunities, and UE 120 may receive the configuration message. For example, the configuration message may include an RRC message. In some aspects, the configuration message may be a dedicated message or a group common message. For example, the configuration message may be addressed to a Radio Network Temporary Identifier (RNTI) associated with UE 120, or to a group RNTI (G-RNTI) and / or multiple RNTIs. In some aspects, one or more second CG-SDT opportunities may be at least partially nested within a first CG-SDT opportunity.

[0109] In some aspects, the configuration message may further indicate one or more search space configurations for responding to the message (e.g., as described in conjunction with reference numeral 615), one or more uplink control information (UCI) multiplexing schemes, one or more timing advance (TA) verification schemes (e.g., as described in conjunction with reference numeral 610), one or more power control schemes for initial transmissions, and / or one or more power control schemes for retransmissions (e.g., when UE 120 must retransmit uplink communication, as described in conjunction with reference numeral 615). For example, the configuration message may provide one or more parameters for UE 120 to apply to formulas (e.g., as defined in 3GPP specifications and / or another standard) to determine power control. In some aspects, the power control for retransmissions may be the same as or different from the power control for initial transmissions.

[0110] In some respects, the first CG-SDT timing and the second CG-SDT timing can be associated with the same CG-SDT group, including UE 120. Therefore, at least a portion of the configuration message can be broadcast to all UEs within the CG-SDT group. For example, the configuration message may include multiple indicators of the CG-SDT timing and associate these indicators with identifiers of different UEs within the CG-SDT group. Additionally or alternatively, at least a portion of the configuration message may be unicast to each UE within the CG-SDT group. For example, a configuration message may indicate a first CG-SDT timing for one or more first UEs in the CG-SDT group, a second CG-SDT timing for one or more second UEs in the CG-SDT group, and so on.

[0111] In some respects, and in combination Figures 4A-4C As described, one or more second CG-SDT timings may be associated with a resource size different from the resource size associated with the first CG-SDT timing. For example, one or more second CG-SDT timings may be smaller or larger in resource size than the first CG-SDT timing.

[0112] Additional or alternative land, and as in combination Figures 4A-4C As described, one or more second CG-SDT timings can be at least partially nested within a first CG-SDT timing in terms of time, frequency, and / or space. Therefore, as combined... Figures 4A-4C As described, the second CG-SDT timing and the first CG-SDT timing may be orthogonal (or at least quasi-orthogonal) in terms of time dimension, frequency dimension and / or associated DMRS resources.

[0113] In some aspects, the configuration message may also indicate one or more mapping or repetition schemes in the time domain for the PUSCH used by the UE 120 to transmit uplink communication (e.g., as described in conjunction with reference numeral 615). For example, as described in conjunction with... Figure 4B The first CG-SDT timing may be repeated in the time domain and at least partially nested within the first CG-SDT timing. Alternatively, the first CG-SDT timing may be repeated in the time domain. By using a mapping or repetition scheme in the time domain, base station 110 allows UE 120 to transmit larger uplink communications across repeated CG-SDT timings. Alternatively, base station 110 allows UE 120 to repeat uplink communications across repeated CG-SDT timings to improve the quality and / or reliability of uplink communications.

[0114] In some respects, one or more second CG-SDT timings may be associated with an MCS different from the MCS associated with the first CG-SDT timing, and may be at least partially nested within the first CG-SDT timing. For example, base station 110 may associate a second CG-SDT timing with an MCS that is higher or lower than the MCS associated with the first CG-SDT timing.

[0115] In addition to, or as an alternative to, configuration messages, base station 110 may send information indicating radio resource allocation, periodicity, transmission scheme, and resource size for a CG-SDT group including UE 120, and UE 120 may receive this information. Furthermore, base station 110 may further send an index indicating the timing of a first CG-SDT, and UE 120 may further receive this index. For example, as in combination with... Figures 4A-4C As described, the index may be based at least in part on one or more frequency resources included in the first CG-SDT timing, one or more time resources included in the first CG-SDT timing, and one or more DMRS resources associated with the first CG-SDT timing.

[0116] Such as combination Figures 4A-4CAs described, the index can be based, at least in part, on ascending order of frequency resources, ascending order of DMRS resources, and ascending order of time resources, but rather sequentially. In some respects, and as in combination Figures 4A-4C As further described, the index may be based at least in part on one or more rules stored by UE 120 and / or one or more rules indicated by base station 110, but rather sequentially.

[0117] In some respects, the information can further indicate the MCS, frequency hopping, and mapping or repetition scheme in the time domain for the CG-SDT group. For example, as in combination Figure 4C As described, one or more second CG-SDT timings can provide frequency hopping. Additionally or alternatively, such as in combination Figure 4B As described, one or more second CG-SDT timings can be repeated in the time domain.

[0118] In some aspects, base station 110 may send information and indexes in a broadcast message, and UE 120 may receive information and indexes in a broadcast message. For example, the information may include multiple indexes of CG-SDT timings and associate the indexes with identifiers of different UEs in the CG-SDT group. Additionally or alternatively, base station 110 may send information and indexes in UE-specific messages, and UE 120 may receive information and indexes in UE-specific messages. For example, base station 110 may send information and indexes associated with a first CG-SDT timing to a first UE in the CG-SDT group, send separate information and indexes associated with a second CG-SDT timing to a second UE in the CG-SDT group, and so on. In some aspects, base station 110 may provide information in a broadcast message and subsequently provide indexes in a UE-specific message.

[0119] As shown in conjunction with reference numeral 610 in the accompanying drawings, UE 120 can maintain TA with base station 110. In some aspects, UE 120 can maintain TA even when UE 120 enters idle mode and / or inactive state. For example, UE 120 can maintain TA when UE 120 is stationary or at least partially stationary (e.g., exhibiting mobility that meets a threshold).

[0120] In some aspects, as described in conjunction with reference numeral 615, UE 120 may verify the uplink TA before transmitting uplink communication. In some aspects, UE 120 may verify the uplink TA at least in part based on one or more criteria provided by base station 110. For example, as described above in conjunction with reference numeral 605, base station 110 may have already transmitted a TA verification scheme, and UE 120 may have already received the TA verification scheme. For example, the TA verification scheme may include a time-based scheme (e.g., the TA is valid for a period of time after synchronization) and / or a measurement-based scheme (e.g., the TA is valid as long as one or more measurements of one or more reference signals continue to satisfy one or more thresholds). In some aspects, UE 120 may measure reference signals (e.g., synchronization signal block (SSB), channel state information reference signal (CSI-RS), and / or another signal to verify the uplink TA). For example, UE 120 may apply one or more criteria from base station 110 to measurements to verify the TA before transmitting uplink communication during a first CG-SDT or a second CG-SDT.

[0121] As shown in conjunction with reference numeral 615, UE 120 may transmit uplink communication within a first CG-SDT or a second CG-SDT, using a radio resource allocation and transmission scheme for the selected CG-SDT, and base station 110 may receive the uplink communication. For example, the uplink communication may include PUSCH transmission. In some aspects, UE 120 may determine whether to transmit during the first or second CG-SDT based on whether base station 110 configures UE 120 for the first or second CG-SDT. For example, as described above, base station 110 may separately provide an index to UE 120 and / or associated with an identifier of UE 120, such that UE 120 may determine whether to use the first or second CG-SDT based at least in part on the index.

[0122] In some respects, and in combination Figure 5 As described, uplink communication may include identifiers based at least in part on an index associated with a first CG-SDT timing or a second CG-SDT timing selected by UE 120 for PUSCH transmission.

[0123] In some aspects, within the search space indicated by the configuration message, base station 110 may send a response at least partially based on uplink communication, and UE 120 may receive such a response. In some aspects, the uplink communication may be associated with an initial transmission or a retransmission. For example, in response to uplink communication, base station 110 may send a Physical Downlink Control Channel (PDCCH) message, and UE 120 may receive the PDCCH message.

[0124] By using combination Figure 6 The described techniques improve the spectral efficiency of CG-SDT transmission for base station 110 and UE 120. Therefore, base station 110 and UE 120 reduce network overhead and resource consumption. Additionally or alternatively, by using the index described in conjunction with reference numeral 605, base station 110 and UE 120 reduce signaling overhead for configuring CG-SDT timing. Therefore, base station 110 and UE 120 reduce network overhead and resource consumption.

[0125] As indicated above, Figure 6 This is provided as an example. Other examples may differ from the one provided. Figure 6 The example described.

[0126] Figure 7 This is a diagram illustrating an example process 700 performed by a UE according to this disclosure. Example process 700 is an example in which a UE (e.g., UE 120) performs operations associated with nested CG-SDT timing.

[0127] like Figure 7 As shown, in some aspects, process 700 may include receiving from a base station (e.g., base station 110) a configuration message (block 710) indicating a radio resource allocation and transmission scheme for one or more first CG-SDT opportunities and one or more second CG-SDT opportunities. For example, a UE (e.g., using antenna 252, modem 254, MIMO detector 256, receive processor 258, controller / processor 280, and / or memory 282) may receive from the base station the configuration message indicating a radio resource allocation and transmission scheme for one or more first CG-SDT opportunities and one or more second CG-SDT opportunities, as described herein. In some aspects, one or more second CG-SDT opportunities are at least partially nested within one or more first CG-SDT opportunities in terms of time, frequency, or a combination thereof.

[0128] like Figure 7As further shown, in some aspects, process 700 may include transmitting uplink communication to the base station during one or more first CG-SDT times or one or more second CG-SDT times using a radio resource allocation and transmission scheme (block 720). For example, a UE (e.g., using antenna 252, transmit processor 264, TXMIMO processor 266, modem 254, controller / processor 280, and / or memory 282) may use the radio resource allocation and transmission scheme as described herein to transmit uplink communication to the base station during one or more first CG-SDT times or one or more second CG-SDT times.

[0129] Process 700 may include additional aspects, such as any single aspect or any combination of aspects described below and / or in conjunction with one or more other process descriptions described elsewhere in this document.

[0130] In a first aspect, one or more first CG-SDT timings and one or more second CG-SDT timings are associated with the same CG-SDT group including the UE. This has the technical effect of reducing signaling overhead from base station 110 by allowing base station 110 to broadcast or multicast at least a portion of configuration messages.

[0131] In the second aspect, alone or in combination with the first aspect, one or more second CG-SDT timings are associated with resource sizes different from those associated with one or more first CG-SDT timings. This has the following technical effect: allowing base station 110 to allocate some UEs to smaller CG-SDT resources (e.g., to UEs expected to have less uplink communication) and allocate other UEs to larger CG-SDT resources (e.g., to UEs expected to have more uplink communication), thereby reducing the waiting time for UEs expected to have more uplink communication while saving network spectrum allocated to UEs expected to have less uplink communication.

[0132] In a third aspect, alone or in combination with one or more of the first and second aspects, a configuration message indicates frequency hopping for one or more first CG-SDT timings or one or more second CG-SDT timings. This has the technical effect of allowing for greater uplink communication using frequency hopping. Additionally or alternatively, this has the technical effect of increasing the reliability and / or quality of uplink communication by allowing uplink communication to be repeated at different frequencies.

[0133] In a fourth aspect, alone or in combination with one or more of the first to third aspects, one or more second CG-SDT opportunities are associated with an MCS different from that associated with one or more first CG-SDT opportunities. This has the following technical effect: allowing base station 110 to assign some UEs to CG-SDT opportunities with higher MCS (e.g., to UEs that are closer and / or associated with better radio conditions) and to assign other UEs to CG-SDT opportunities with lower MCS (e.g., to UEs that are farther away and / or associated with worse radio conditions) in order to increase the throughput of UEs associated with strong radio signals, while increasing the quality and / or reliability of UEs associated with weak radio signals.

[0134] In the fifth aspect, alone or in combination with one or more of the first through fourth aspects, the configuration message indicates one or more mapping or repetition schemes in the time domain for the PUSCH used to transmit uplink communication. This has the technical effect of allowing UE 120 to transmit larger uplink communications in the time domain. Additionally or alternatively, this has the technical effect of allowing UE 120 to increase reliability and / or quality by repeating uplink communications across the time domain.

[0135] In a sixth aspect, either alone or in combination with one or more of the first to fifth aspects, process 700 further includes receiving, from the base station and within a search space indicated by a configuration message, a response at least partially based on uplink communication, wherein the uplink communication is associated with an initial transmission or retransmission. This has the technical effect of allowing UE 120 to determine whether to retransmit the uplink communication to base station 110. Therefore, UE 120 ensures that base station 110 receives the uplink communication and subsequently conserves power and processing resources once the uplink communication has been received.

[0136] In a seventh aspect, alone or in combination with one or more of the first to sixth aspects, the uplink communication includes an identifier at least in part based on an index associated with one or more first CG-SDT timings or one or more second CG-SDT timings selected by the UE for DMRS and PUSCH transmission. This has the following technical effect: it allows the UE 120 to scramble the uplink communication, enabling the base station 110 to distinguish the uplink communication from other signals. Additionally, the UE 120 can scramble the uplink communication without receiving another identifier from the base station 110 for scrambling, which saves power, processing resources, and network overhead.

[0137] In the eighth aspect, alone or in combination with one or more of the first to seventh aspects, the configuration message also indicates at least one of the following: one or more search space configurations for responding to the message, one or more UCI multiplexing schemes, one or more TA authentication schemes, one or more power control schemes for initial transmission, or one or more power control schemes for retransmission.

[0138] In a ninth aspect, either alone or in combination with one or more of the first to eighth aspects, process 700 further includes: verifying (e.g., using a transmit processor 264, a TX MIMO processor 266, a modem 254, a controller / processor 280, and / or a memory 282) an uplink TA at least in part based on one or more criteria provided by the base station before transmitting uplink communication, such that uplink communication is transmitted at least in part based on the verified uplink TA. This has the technical effect of increasing the reliability and / or quality of uplink communication by ensuring that the UE 120 does not transmit uplink communication based on inaccurate TAs.

[0139] In the tenth aspect, either alone or in combination with one or more of the first to ninth aspects, the UE is in an inactive mode, an idle state, or a connected mode.

[0140] although Figure 7 The example box for process 700 is shown, but in some respects, process 700 may include more than Figure 7 The boxes depicted may include more boxes, fewer boxes, different boxes, or boxes arranged in a different manner.

For example, the UE (e.g., using antenna 252, modem 254, MIMO detector 256, receive processor 258, controller / processor 280, and / or memory 282) may receive from the base station the information indicating the resource allocation, periodicity, and resource size for a CG-SDT group including the UE, as described herein.
