Technical Field

[0004] The various aspects of this disclosure generally relate to wireless communication systems, and more particularly to the use of cyclic prefixes (CP) in wireless communication. Background Technology

[0005] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, message sending and receiving, and broadcasting. These systems can be multiple access systems capable of supporting communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems 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, and Single Carrier Frequency Division Multiple Access (SC-FDMA) systems.

[0006] These multiple access technologies have been adopted in various telecommunications standards to provide a common protocol enabling different wireless devices to communicate at the city, national, regional, and even global levels. For example, fifth-generation (5G) wireless communication technology (which may be referred to as 5G New Radio (5G NR)) is designed to expand and support a diverse range of use cases and applications relative to current mobile network generations. In one aspect, 5G communication technologies can include: enhanced mobile broadband for human-centric use cases of accessing multimedia content, services, and data; ultra-reliable low latency communication (URLLC) with certain specifications regarding latency and reliability; and massive machine-type communication, which allows for a very large number of connected devices and the transmission of relatively small amounts of non-latency-sensitive information. However, with the continued growth in demand for mobile broadband access, further improvements to 5G communication technologies and beyond may be expected. Summary of the Invention

[0027] The various aspects will now be described with reference to the accompanying drawings. In the following description, numerous specific details are set forth for illustrative purposes to provide a thorough understanding of one or more aspects. However, it will be apparent that such aspects can be practiced without these specific details.

[0028] The described features generally relate to supporting multiple Cyclic Prefix (CP) types in wireless communications. As described, nodes in a wireless network (such as a network with a fifth-generation (5G) New Radio (NR) configuration) can be configured with different CP types for different links, different signals transmitted on different links, etc. In one example, a node can be configured to use different CP types for each of at least two signals to communicate signals (e.g., transmit or receive) with one or more other nodes, where using different CP types can also result in different timelines for communication. For example, a base station can use a normal CP to transmit one or more broadcast signals and can multiplex one or more unicast signals using an extended CP with the one or more broadcast signals. In this example, a user equipment (UE) or other node can receive the one or more broadcast signals and / or unicast signals, which can be multiplexed (e.g., in a given time slot) and can each use a different CP type. In one example, the time slot format configuration for normal CP communication and extended CP communication can be coordinated to provide a desired level of compatibility to minimize conflicting communication directions (e.g., uplink to downlink) between symbols in the time slot.

[0029] For example, an NR UE can be semi-statically configured with a specific set of parameters (e.g., the parameter set may refer to CP overhead and / or subcarrier spacing (SCS)), where the NR can support extended CP for at least a 60 kHz SCS. In this configuration, for example, a time slot may include 12 orthogonal frequency division multiplexing (OFDM) symbols. The NR can also support normal CP, where a time slot may include 14 OFDM symbols. Additionally, in the NR, the uplink and downlink can be configured with different CP types (e.g., normal CP or extended CP). Additional configuration for using CP may be necessary.

[0030] Additionally, the slot format configuration for wireless networks (such as 5G NR) can be semi-static and UE-dependent. Each slot may include multiple symbols, each of which can be configured for downlink, uplink, or flexible communication. Slots configured for flexible communication can be dynamically reconfigured for downlink or uplink in a dynamic and / or UE-dependent manner (e.g., by dynamically configuring flexible symbols using a group-shared physical downlink control channel (GC-PDCCH)). Furthermore, CP type or length (e.g., normal CP, extended CP, etc.) configuration can be semi-static and UE-dependent, and different CP types can be associated with different timelines (e.g., different numbers of symbols in slots of similar length, where timelines may correspond to the number of symbols in a slot, the corresponding duration of a symbol or slot, etc.). In a specific example, some signals (such as the Primary Synchronization Signal (PSS), Secondary Synchronization Signal (SSS), Multicast Physical Downlink Shared Channel (PDSCH), etc.) can be configured to use the normal CP, while other unicast transmissions can be configured with extended CP in the same time slot. This can result in the multiplexing of normal CP communication and extended CP communication in the same time slot. The normal CP time slot format can be based on using a first number of OFDM symbols per time slot (e.g., 14), while the extended CP time slot format can be based on using a second number of OFDM symbols per time slot (e.g., 12), which can result in different communication timelines for each time slot.

[0031] The aspects described herein relate to the multiplexing of normal CP communication and extended CP communication, which may include adapting a time slot format for use with another CP type based on a time slot format defined for one CP type, wherein these time slot formats may be based on different timelines. Using the concepts described herein to adapt time slot formats can mitigate or minimize conflicts in the transmission directions between symbols of time slot formats occurring at the same or similar times. In one example, a network node may derive a time slot format for another CP type based on a time slot format used for one CP type and / or based on the associated timeline of the CP type. In another example, a network node (e.g., a base station) may configure another network node (e.g., a UE) to have a time slot format to be used for each CP type (e.g., by specifying an indicator representing the time slot format, such as a Time Slot Format Indicator (SFI) in the configuration), wherein the time slot format may exhibit a certain level of compatibility between various types of configured symbols in the time slot. In any case, a network node may be configured accordingly to convey multiplexed signals based on different CP types and / or associated with different corresponding timelines, while reducing conflicts in the communication directions between symbols on multiple timelines.

[0032] The following will be referenced Figure 1-7 To present the described features in more detail.

[0033] As used herein, the terms “component,” “module,” “system,” and similar terms are intended to include computer-related entities such as, but not limited to, hardware, firmware, combinations of hardware and software, software, or software in execution. For example, a component can be, but is not limited to, a process running on a processor, a processor, an object, an executable, a thread of execution, a program, and / or a computer. For illustration, both an application running on a computing device and the computing device itself can be components. One or more components may reside within a process and / or a thread of execution, and components may be localized on a single computer and / or distributed across two or more computers. Furthermore, these components can be executed from various computer-readable media on which various data structures are stored. These components can communicate by means of local and / or remote processes, such as by means of signals having one or more data packets, such as data from a component interacting with a local system, another component in a distributed system, and / or interacting with other systems across a network such as the Internet.

[0034] The technologies described herein can be used in various wireless communication systems, such as CDMA, TDMA, FDMA, OFDMA, SC-FDMA, and others. The terms "system" and "network" are generally used interchangeably. CDMA systems implement radio technologies such as CDMA2000 and Universal Terrestrial Radio Access (UTRA). CDMA2000 encompasses the IS-2000, IS-95, and IS-856 standards. IS-2000 versions 0 and A are often referred to as CDMA2000 1X, 1X, etc. IS-856 (TIA-856) is often referred to as CDMA2000 1xEV-DO, High Rate Packet Data (HRPD), etc. UTRA includes Wideband CDMA (WCDMA) and other CDMA variants. TDMA systems implement radio technologies such as Global System for Mobile Communications (GSM). OFDMA systems can implement technologies such as Ultra Mobile Broadband (UMB), Evolved UTRA (E-UTRA), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, and Flash-OFDM. TMRadio technologies such as UTRA and E-UTRA are part of the Universal Mobile Telecommunications System (UMTS). 3GPP Long Term Evolution (LTE) and LTE Advanced (LTE-A) are newer versions of UMTS using E-UTRA. UTRA, E-UTRA, UMTS, LTE, LTE-A, and GSM are described in documents from an organization called the Third Generation Partnership Project (3GPP). CDMA2000 and UMB are described in documents from an organization called the Third Generation Partnership Project 2 (3GPP2). The technologies described herein can be used with the systems and radio technologies mentioned above, as well as with other systems and radio technologies, including cellular (e.g., LTE) communications sharing a radio spectrum band. However, the following description describes LTE / LTE-A systems for illustrative purposes, and LTE terminology is used in most of the following description, but these technologies can also be applied beyond LTE / LTE-A applications (e.g., to 5G networks or other next-generation communication systems).

[0035] The following description provides examples and is not intended to limit the scope, applicability, or examples set forth in the claims. Changes may be made to the function and arrangement of the elements discussed without departing from the scope of this disclosure. Various procedures or components may be appropriately omitted, substituted, or added to the examples. For example, the described methods may be performed in a different order than described, and various steps may be added, omitted, or combined. Furthermore, features described with reference to some examples may be combined in other examples.

[0036] Various aspects or features will be presented in the form of systems that may include several devices, components, modules, and the like. It should be understood and appreciated that various systems may include additional devices, components, modules, etc., and / or may not include all the devices, components, modules, etc. discussed in conjunction with the accompanying drawings. Combinations of these approaches may also be used.

[0037] Figure 1 Examples of wireless communication systems 100 according to various aspects of this disclosure are described. Wireless communication system 100 may include one or more base stations 105, one or more UEs 115, and a core network 130. Core network 130 provides user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. Base stations 105 may interface with core network 130 via backhaul link 132 (e.g., S1, etc.). Base stations 105 may perform radio configuration and scheduling for communication with UEs 115, or may operate under the control of a base station controller (not shown). In various examples, base stations 105 may communicate with each other directly or indirectly (e.g., via core network 130) on backhaul link 134 (e.g., X2, etc.), which may be a wired or wireless communication link.

[0038] Base station 105 can wirelessly communicate with UE 115 via one or more base station antennas. Each base station 105 can provide communication coverage for its respective geographical coverage area 110. In some examples, base station 105 may be referred to as a network entity, base transceiver station, radio base station, access point, radio transceiver, B-node, evolved B-node (eNB), home B-node, home evolved B-node, gNB (e.g., in 5G NR), or some other suitable term. The geographical coverage area 110 of base station 105 may be divided into sectors (not shown) that constitute only a part of that coverage area. Wireless communication system 100 may include different types of base stations 105 (e.g., macro base stations or small cell base stations). There may be overlapping geographical coverage areas 110 of different technologies.

[0039] In some examples, wireless communication system 100 may be or include a Long Term Evolution (LTE) or LTE-Advanced (LTE-A) network. Wireless communication system 100 may also be a next-generation network, such as a 5G wireless communication network. In LTE / LTE-A networks, the term evolved B-node (eNB) (e.g., or gNB in ​​a 5G network) may generally be used to describe base station 105, while the term UE may generally be used to describe UE 115. Wireless communication system 100 may be a heterogeneous LTE / LTE-A network, where different types of eNBs provide coverage across various geographic areas. For example, each eNB or base station 105 may provide communication coverage for macrocells, small cells, or other types of cells. Depending on the context, the term "cell" is a 3GPP term that may be used to describe a base station, a carrier or component carrier associated with a base station, or the coverage area (e.g., a sector, etc.) of a carrier or base station.

[0040] Macrocells can cover relatively large geographical areas (e.g., with a radius of several kilometers) and allow unrestricted access by UEs 115 that have service subscriptions with network providers.

[0041] Small cells may include lower-power base stations (compared to macro cells) that can operate in the same or different (e.g., licensed, unlicensed, etc.) frequency bands as macro cells. Depending on the examples, small cells may include picocells, femtocells, and microcells. A picocell may, for example, cover a small geographic area and allow unrestricted access by UE 115 with a service subscription to a network provider. A femtocell may also cover a small geographic area (e.g., a residential area) and provide restricted access by UE 115 associated with that femtocell (e.g., UE 115 in a closed subscriber group (CSG), UE 115 of a user in a residence, etc.). An eNB used for a macrocell may be referred to as a macro eNB, gNB, etc. An eNB used for a small cell may be referred to as a small cell eNB, pico eNB, femtocell eNB, or home eNB. An eNB may support one or more (e.g., two, three, four, etc.) cells (e.g., component carriers).

[0042] The communication network, adaptable to various examples disclosed, can be a packet-based network operating according to a layered protocol stack, and the data in the user plane can be IP-based. The Packet Data Convergence Protocol (PDCP) layer can provide header compression, cryptography, integrity protection, etc., for IP packets. The Radio Link Control (RLC) layer can perform packet segmentation and reassembly for communication on logical channels. The Media Access Control (MAC) layer can perform priority handling and multiplex logical channels into transport channels. The MAC layer can also use HARQ to provide MAC layer retransmission, thereby improving link efficiency. In the control plane, the Radio Resource Control (RRC) protocol layer can provide the establishment, configuration, and maintenance of RRC connections between UE 115 and base station 105. The RRC protocol layer can also be used by the core network 130 to support radio bearers for user plane data. In the physical (PHY) layer, transport channels can be mapped to physical channels.

[0043] UE 115 can be distributed throughout the wireless communication system 100, and each UE 115 can be stationary or mobile. UE 115 may also include, or be referred to by those skilled in the art, as a mobile station, subscriber station, mobile unit, subscriber unit, wireless unit, remote unit, mobile device, wireless device, wireless communication device, remote device, mobile subscriber station, access terminal, mobile terminal, wireless terminal, remote terminal, handheld device, user agent, mobile client, client, or any other suitable term. UE 115 can be a cellular phone, personal digital assistant (PDA), wireless modem, wireless communication device, handheld device, tablet computer, laptop computer, cordless phone, wireless local loop (WLL) station, entertainment device, vehicle-mounted component, etc. The UE can communicate with various types of base stations and network equipment (including macro eNBs, small cell eNBs, relay base stations, etc.).

[0044] The communication link 125 shown in the wireless communication system 100 can carry UL transmission from UE 115 to base station 105, or downlink (DL) transmission from base station 105 to UE 115. Downlink transmission may also be referred to as forward link transmission, and uplink transmission may also be referred to as reverse link transmission. Each communication link 125 may include one or more carriers, where each carrier may be a signal composed of multiple subcarriers (e.g., waveform signals of different frequencies) modulated according to the various radio techniques described above. Each modulated signal may be transmitted on a different subcarrier and may carry control information (e.g., reference signals, control channels, etc.), overhead information, user data, etc. The communication link 125 may use frequency division duplex (FDD) (e.g., using paired spectrum resources) or time division duplex (TDD) operation (e.g., using unpaired spectrum resources) to transmit bidirectional communication. Frame structures for FDD (e.g., frame structure type 1) and frame structures for TDD (e.g., frame structure type 2) may be defined.

[0045] In various aspects of the wireless communication system 100, the base station 105 or UE 115 may include multiple antennas to employ an antenna diversity scheme to improve the communication quality and reliability between the base station 105 and the UE 115. Additionally or alternatively, the base station 105 or UE 115 may employ multiple-input multiple-output (MIMO) technology, which can utilize multipath environments to transmit multiple spatial layers carrying the same or different encoded data.

[0046] The wireless communication system 100 can support operation on multiple cells or carriers, a feature that may be referred to as carrier aggregation (CA) or multi-carrier operation. A carrier may also be referred to as a component carrier (CC), layer, channel, etc. The terms “carrier,” “component carrier,” “cell,” and “channel” are used interchangeably herein. The UE 115 may be configured with multiple downlink CCs for carrier aggregation and one or more uplink CCs. Carrier aggregation can be used in conjunction with both FDD and TDD component carriers.

[0047] In various aspects of the wireless communication system 100, one or more of the base stations 105 may include a multiplexing component 240 for multiplexing communications using different CP types based on different timelines, which may be based on lengths associated with the CP type. One or more of the UEs 115 may include a communication component 340 for receiving and decoding multiplexed communications based on different CP types. Additionally, in some examples, the one or more UEs 115 may additionally or alternatively include the multiplexing component 240 to multiplex communications of different CP types according to the aspects described herein, and / or the one or more base stations 105 may include the communication component 340 for receiving and decoding multiplexed communications. Moreover, in one example, different UEs 115 may include the multiplexing component 240 and / or the communication component 340 to facilitate UE-to-UE communication, etc.

[0048] Now go to Figure 2-8 The aspects described herein are illustrated with reference to one or more components and one or more methods capable of performing the actions or operations described herein, wherein the aspects shown in dashed lines may be optional. Although the following... Figure 4-5 The operations described herein are presented in a specific order and / or are presented as being performed by example components, but it should be understood that the order of these actions and the components performing the actions may vary depending on the implementation. Furthermore, it should be understood that the following actions, functions, and / or described components may be performed by a specially programmed processor, a processor executing specially programmed software or a computer-readable medium, or by any other combination of hardware and / or software components capable of performing the described actions or functions.

[0049] refer to Figure 2The diagram illustrates a block diagram 200 comprising a portion of a wireless communication system having multiple UEs 115 communicating with a base station 105 via a communication link 125, wherein the base station 105 is also connected to a network 210. UEs 115 may be examples of the UEs described in this disclosure, configured to receive and decode multiplexed communications of different CP types (e.g., communications that may overlap in the time domain). Furthermore, base station 105 may be examples of base stations described in this disclosure (e.g., eNB, gNB, other types of access points, etc., providing one or more macrocells, small cells, etc.), configured to multiplex and transmit communications using different CP types that may correspond to different communication timelines.

[0050] On the one hand, Figure 2 The base station may include one or more processors 205 and / or memory 202, which may be combined with multiplexing component 240 to operate in order to perform the functions and methods given in this disclosure (e.g., Figure 4 Method 400, etc. According to various aspects of this disclosure, multiplexing component 240 may include one or more components for multiplexing communications with different CP types (and thus potentially different communication timelines). In one example, multiplexing component 240 may include a time slot format indication component 242 for indicating the time slot format associated with a first CP type, and / or a time slot format derivation component 244 for deriving or interpolating (and / or additionally indicating) a second time slot format associated with a second CP type.

[0051] One or more processors 205 may include a modem 220 using one or more modem processors. Various functions relating to the multiplexing component 240 and / or its sub-components may be included in the modem 220 and / or processor 205, and in one aspect, may be performed by a single processor, while in other aspects, different functions may be performed by a combination of two or more different processors. For example, in one aspect, the one or more processors 205 may include a modem processor, or a baseband processor, or a digital signal processor, or a transmit processor, or a transceiver processor associated with transceiver 270, or any one or any combination of a system-on-a-chip (SoC). Specifically, the one or more processors 205 may perform the functions and components included in the multiplexing component 240. In another example, the multiplexing component 240 may operate at one or more communication layers (such as a physical layer (e.g., layer 1 (L1)), a media access control (MAC) layer (e.g., layer 2 (L2)), a PDCP layer, or an RLC layer (e.g., layer 3 (L3)) etc.) to multiplex communications and / or transmit indications for one or more CP types of timeslot formats, etc.

[0052] In some examples, the multiplexing component 240 and each of the sub-components may include hardware, firmware, and / or software, and may be configured to execute code or execute instructions stored in memory (e.g., a computer-readable storage medium, such as memory 202 discussed below). Moreover, in one aspect, Figure 2 Base station 105 may include a radio frequency (RF) front-end 290 and a transceiver 270 for receiving and transmitting radio transmissions to, for example, UE 115. Transceiver 270 may coordinate with modem 220 to receive signals for multiplexing component 240 or transmit signals generated by multiplexing component 240 to the UE. RF front-end 290 may be connected to one or more antennas 273 and may include one or more switches 292, one or more amplifiers (e.g., power amplifier (PA) 294 and / or low-noise amplifier 291), and one or more filters 293 for transmitting and receiving RF signals, transmitting and receiving signals, etc., on uplink and downlink channels. In one aspect, components of RF front-end 290 may be connected to transceiver 270. Transceiver 270 may be connected to one or more of modem 220 and processor 205.

[0053] Transceiver 270 can be configured to transmit (e.g., via transmitter (TX) radio 275) and receive (e.g., via receiver (RX) radio 280) wireless signals via antenna 273 through RF front end 290. In one aspect, transceiver 270 can be tuned to operate at a specified frequency so that base station 105 can communicate with, for example, UE 115. In another aspect, for example, modem 220 can configure transceiver 270 to operate at a specified frequency and power level based on the configuration of base station 105 and the communication protocol used by modem 220.

[0054] Figure 2 The base station 105 may further include a memory 202, such as for storing local versions of data and / or applications used herein, or multiplexing components 240 and / or one or more sub-components executed by the processor 205. The memory 202 may include any type of computer-readable medium that can be used by a computer or processor 205, such as random access memory (RAM), read-only memory (ROM), tape, magnetic disk, optical disk, volatile memory, non-volatile memory, and any combination thereof. In one aspect, for example, the memory 202 may be a computer-readable storage medium storing one or more computer-executable codes defining multiplexing components 240 and / or one or more sub-components thereof. Additionally or alternatively, the base station 105 may include a bus 211 for coupling one or more of the RF front-end 290, transceiver 270, memory 202, or processor 205, and for exchanging signaling information between each component and / or sub-component of the base station 105.

[0055] On one hand, processors 205 may correspond to the combination of Figure 9 The base station described in the text refers to one or more of the processors. Similarly, memory 202 may correspond to the combination of... Figure 9 The memory described by the base station in the text.

[0056] refer to Figure 3 The diagram illustrates a block diagram 300 comprising a portion of a wireless communication system having multiple UEs 115 communicating with a base station 105 via a communication link 125, wherein the base station 105 is also connected to a network 210. UEs 115 may be examples of the UEs described in this disclosure, configured to receive and decode multiplexed communications of different CP types (e.g., communications that may overlap in the time domain). Furthermore, base station 105 may be examples of base stations described in this disclosure (e.g., eNB, gNB, other types of access points, etc., providing one or more macrocells, small cells, etc.), configured to multiplex and transmit communications using different CP types that may correspond to different communication timelines.

[0057] On the one hand, Figure 3 The UE 115 may include one or more processors 305 and / or memory 302, which may be operated in conjunction with communication component 340 to perform the functions and methods given in this disclosure (e.g., Figure 5 Method 500, etc. According to various aspects of this disclosure, communication component 340 may include one or more components for receiving and decoding multiplexed communications with different CP types. For example, communication component 340 may include a time slot format determination component 342 for determining the time slot format of received communications associated with a first CP type, and / or a time slot format derivation component 344 for deriving the time slot format of received communications associated with a second CP type. In one example, communication component 340 may receive and decode communications received according to a first CP type and a second CP type.

[0058] One or more processors 305 may include a modem 320 using one or more modem processors. Various functions relating to the communication component 340 and / or its sub-components may be included in the modem 320 and / or processor 305, and in one aspect, may be performed by a single processor, while in other aspects, different functions may be performed by a combination of two or more different processors. For example, in one aspect, the one or more processors 305 may include a modem processor, or a baseband processor, or a digital signal processor, or a transmit processor, or a transceiver processor associated with transceiver 370, or any one or any combination of a system-on-a-chip (SoC). Specifically, the one or more processors 305 may perform the functions and components included in the communication component 340. In another example, the communication component 340 may operate at one or more communication layers (such as the physical layer or L1, the MAC layer or L2, the PDCP / RLC layer or L3, etc.) to receive communications with different CP types, receive time slot format indicators for communications relating to one or more of the different CP types, etc.

[0059] In some examples, communication component 340 and each of the sub-components may include hardware, firmware, and / or software, and may be configured to execute code or execute instructions stored in memory (e.g., a computer-readable storage medium, such as memory 302 discussed below). Moreover, in one aspect, Figure 3 UE 115 may include an RF front-end 390 and a transceiver 370 for receiving and transmitting radio transmissions to, for example, base station 105. Transceiver 370 may coordinate with modem 320 to receive signals including packets (e.g., and / or one or more associated PDUs). RF front-end 390 may be connected to one or more antennas 373 and may include one or more switches 392, one or more amplifiers (e.g., PA 394 and / or LNA 391), and one or more filters 393 for transmitting and receiving RF signals on uplink and downlink channels. In one aspect, components of RF front-end 390 may be connected to transceiver 370. Transceiver 370 may be connected to one or more of modem 320 and processor 305.

[0060] Transceiver 370 can be configured to transmit (e.g., via transmitter (TX) radio 375) and receive (e.g., via receiver (RX) radio 380) wireless signals via antenna 373 through RF front end 390. In one aspect, transceiver 370 can be tuned to operate at a specified frequency so that UE 115 can communicate with, for example, base station 105. In another aspect, for example, modem 320 can configure transceiver 370 to operate at a specified frequency and power level based on the configuration of UE 115 and the communication protocol used by modem 320.

[0061] Figure 3 The UE 115 may further include a memory 302, such as for storing data used herein and / or a local version of the application, or communication components 340 and / or one or more of their sub-components executed by the processor 305. The memory 302 may include any type of computer-readable medium that can be used by the computer or processor 305, such as RAM, ROM, tape, magnetic disk, optical disk, volatile memory, non-volatile memory, and any combination thereof. In one aspect, for example, the memory 302 may be a computer-readable storage medium storing one or more computer-executable codes defining communication components 340 and / or one or more of their sub-components. Additionally or alternatively, the UE 115 may include a bus 311 for coupling one or more of the RF front-end 390, transceiver 370, memory 302, or processor 305, and for exchanging signaling information between each component and / or sub-component of the UE 115.

[0062] On one hand, processors 305 may correspond to the combination of Figure 9 The UE describes one or more of the processors. Similarly, memory 302 may correspond to the combination of Figure 9 The memory described by the UE in the text.

[0063] Figure 4 A flowchart illustrating an example of a method 400 for multiplexing communications with different CP types (e.g., via a base station) is provided. In one example, the UE may also perform the functions described in method 400 and / or include... Figure 2 The corresponding components can reuse communication with different CP types.

[0064] Optionally, at block 402, a first timeslot format for the first CP type can be determined. In one aspect, the timeslot format indicating component 242 can determine the first timeslot format for the first CP type, for example, in conjunction with processor 205, memory 202, transceiver 270, multiplexing component 240, etc. For example, the timeslot format indicating component 242 can select the first timeslot format based on one or more parameters related to communication with UE 115, such as signal strength or quality, load at base station 105, buffer status reports from UE 115 indicating the amount of data to be transmitted, quality of service (QoS), bit rate, or other performance metrics of one or more links or bearers. For example, the timeslot format can correspond to the number and / or pattern of symbols defined in the timeslot for the communication direction (e.g., downlink, uplink, etc.). The timeslot format may also include one or more flexible symbols that can be dynamically configured for downlink or uplink communication. In one example, wireless technologies (such as 5G NR) can define several time slot formats that specify the number and / or mode of downlinks, uplinks, or flexible symbols within a time slot.

[0065] For example, Figure 6 Examples of time slot formats 600 and 610 defined for a normal CP in 5G NR are explained. For example, time slot format 600 includes three downlink symbols, followed by eight flexible symbols, followed by three uplink symbols, for a total of 14 symbols in the time slot. In another example, time slot format 610 includes two downlink symbols, followed by one flexible symbol, followed by four uplink symbols, followed by two downlink symbols, followed by one flexible symbol, followed by four uplink symbols, for a total of 14 symbols in the time slot. In one example, time slot format indicative component 242 can select the time slot format for a first CP type (e.g., normal CP) based on one or more time slot formats defined in a wireless communication technology such as 5G NR.

[0066] Optionally, at block 404, an indicator of the first time slot format can be transmitted. In one aspect, the time slot format indicator component 242 can transmit the first time slot format indicator, for example, in conjunction with processor 205, memory 202, transceiver 270, multiplexing component 240, etc. For example, the time slot format indicator component 242 can transmit the first time slot format indicator to one or more UEs 115 using indicators in configuration or related signaling, such as in downlink control information (DCI) in the downlink control channel (e.g., PDCCH). Moreover, in one example, the time slot format indicator component 242 can determine and / or indicate the communication direction (e.g., downlink or uplink) of flexible symbols in a time slot in a separate configuration. As described, the time slot format indicator component 242 can determine and / or transmit the indicator semi-statically, dynamically, etc., because the selected format can vary from UE to UE, from group to group, etc. For example, the time slot format indication component 242 can transmit time slot formats or related indicators in Radio Resource Control (RRC) signals, Dedicated Control Channel communications, etc. In one example, the time slot format indication component 242 can indicate an initial time slot format and can override the initial time slot format with a new time slot format in dynamic signaling.

[0067] Optionally, at block 406, a second timeslot format for the second CP type can be derived based on the first timeslot format. In one aspect, the timeslot format export component 244 can, for example, be combined with processors 205, memory 202, transceiver 270, multiplexing component 240, etc., to derive a second timeslot format for the second CP type based on the first timeslot format. As further described herein, this can include interpolating the second timeslot format from the first timeslot format such that one or more symbols are defined in the second timeslot format for downlink communication, uplink communication, flexible communication, etc., based on how the symbols are defined in the first timeslot format. In another example, this can include selecting a timeslot format for the second CP type that is indicated to be compatible with (or otherwise mapped to) the first timeslot format for the first CP type. In the latter example, base station 105 may include (e.g., stored in memory 202) a mapping between a timeslot format for a first CP type (e.g., normal CP) and a timeslot format for a second CP type (e.g., extended CP), which can be used to multiplex communications.

[0068] Furthermore, for example, CP types can have different parameter sets and can therefore be associated with different timelines used for communication. For example, in 5G NR, communication resources can be defined as a set of frequency resources (e.g., multiple subcarriers) on a set of time resources (e.g., multiple OFDM symbols). In one example, in 5G NR, a time slot can be defined to include multiple OFDM symbols, each OFDM symbol having several subcarriers determined based on the subcarrier spacing, and the number of OFDM symbols in the time slot can be at least partially determined based on the CP type used for the time slot (e.g., normal CP, extended CP, etc.). In one example, 5G NR can support OFDM symbol-level time division multiplexing for different CP types, as described herein. The allocation of OFDM symbols in each parameter set or CP type can be based on the corresponding OFDM symbol grid, where the OFDM symbol grid can be defined and repeated every 0.5 milliseconds (ms).

[0069] For example, for subcarrier spacing SCS NCP =2 μNCP • At 15 kHz, the normal CP symbol grid can be defined as:

[0070]

[0071] T s =1 / (30.72×10 6 [sec]

[0072]

[0073] k = 0, ..., 7·2 μNCP -1 (0.5ms span)

[0074] In another example, for the subcarrier spacing SCS ECP =2 μECP • 15 [kHz], the extended CP symbol grid can be defined as:

[0075]

[0076]

[0077] k = 0, ..., 6·2 μECP -1 (0.5ms span)

[0078] In 5G NR, for example, it can be assumed that the same subcarrier spacing (SCS) is configured for different CP types (e.g., μ). NCP =μ ECPHowever, different SCSs can also be configured for different CP types. In one example, uplink and downlink communication for any CP type can use different SCSs within a time slot, and / or different CP types can use different SCSs within a time slot. Additionally, sub-band frequency division multiplexing for different CP types can be used. In any case, for the coexistence of these signals in 5G NR with normal / extended CP LTE signals, it may be desirable to use the symbol grid (as defined above) for normal CP type communication and extended CP type communication to determine the symbol alignment and corresponding time slot format within a time slot.

[0079] For example, because different CP types can have different numbers of symbols per slot (e.g., and thus can be associated with different timelines for a given slot), symbol boundaries may not align, and deriving a slot format that is compatible (or largely compatible) in communication directions may be based on logic to resolve potential conflicts (where symbols for one CP type overlap with symbols for another CP type that have different communication directions (e.g., downlink, uplink, flexible, etc.)). In one example, slot format derivation component 244 may use this logic to derive a slot format for a second CP type based on the slot format of the first CP type, or the slot format may be associated in a configuration and this association may be based on this logic.

[0080] exist Figure 6An example is shown illustrating time slot formats 600 and 610 for normal CP and corresponding time slot formats 602 and 612 for extended CP, which can be defined to be compatible with time slot formats 600 and 610. As shown, time slot formats 600 and 610 can be defined based on a parameter set of 14 OFDM symbols per time slot (e.g., for normal CP) and can correspond to time slot formats 27 and 55 defined in 5G NR, respectively. Alternatively, for example, time slot formats 602 and 612 can be defined based on a parameter set of 12 OFDM symbols per time slot (e.g., for extended CP). In the depicted examples, time slot formats 600 and 602 may have a certain level of compatibility (or may be referred to as compatible) such that at least some symbols in time slot format 600 with a specific communication direction (e.g., downlink, uplink, or flexible) overlap in the time domain, while at least some other symbols in time slot format 602 have a similar communication direction. Similarly, time slot formats 610 and 612 similarly have a level of compatibility. In one example, time slot formats 600 and 602 may be defined for 5G NR communication and may be associated with each other as compatible time slot formats in the configuration (and similarly, time slot formats 610 and 612). However, in another example, time slot format derivation component 244 may interpolate time slot format 602 for extended CP based on the determined time slot format determined and / or indicated by time slot format indication component 242. Interpolation can be performed based on a rule set, which may be configured at base station 105 or UE 115, provided to UE 115 in a configuration from base station 105, etc. Using rules to determine the format of time slot(s) can, for example, help avoid severe inter-symbol / inter-carrier interference between communications.

[0081] Figure 7 The section explains local time slot formats, which describe examples of rules for determining the communication direction of symbols in an extended CP time slot format based on a determined or indicated normal CP time slot format. For example, as shown at 700, when two downlink symbols in the normal CP time slot format overlap with symbols in the extended CP time slot format, the symbols in the extended CP time slot format can be interpolated as downlink symbols. Similarly, as shown at 702, when two uplink symbols in the normal CP time slot format overlap with symbols in the extended CP time slot format, the symbols in the extended CP time slot format can be interpolated as uplink symbols.

[0082] For example, when downlink symbols and adjacent flexible symbols in the normal CP time slot format overlap with symbols in the extended CP time slot format, the symbols in the extended CP time slot format can be interpolated as downlink symbols (as shown at 704) or as flexible symbols (as shown at 706). Similarly, for example, when uplink symbols and adjacent flexible symbols in the normal CP time slot format overlap with symbols in the extended CP time slot format, the symbols in the extended CP time slot format can be interpolated as uplink symbols (as shown at 708) or as flexible symbols (as shown at 710). In one example, the rule for determining whether a symbol in the extended CP slot format is downlink / uplink or flexible can be based on one or more measurable criteria, such as the portion of the symbol in the normal CP slot format that overlaps with the symbol in the extended CP slot format (e.g., if downlink / uplink symbols in the normal CP slot format overlap more with symbols in the extended CP format than flexible symbols, the symbols in the extended CP format can be interpolated as downlink / uplink).

[0083] In another example, when downlink symbols and adjacent uplink symbols in the normal CP slot format overlap with symbols in the extended CP slot format, the symbols in the extended CP slot format can be interpolated as downlink symbols (as shown at 712), as uplink symbols (as shown at 714), or as reserved symbols (as shown at 716) (e.g., where a reserved symbol may indicate that any transmission or reception on that symbol is prohibited). In one example, the rules used to determine whether a symbol in the extended slot format is downlink, uplink, or reserved may indicate or otherwise be based on one or more measurable criteria, such as the portion of the symbol in the normal CP slot format that overlaps with the symbol in the extended CP slot format, interference criteria, etc. In any case, in a particular example, the slot format derivation component 244 can derive slot format 602 from slot format 600 using a set of rules, and / or can derive slot format 612 based on slot format 610. In any case, the derived timeslot format for the second CP (e.g., extended CP) may have at least some level of compatibility with the first timeslot format for the first CP (e.g., normal CP), such that at least some overlapping symbols may have at least a portion of time with the same communication direction (or one or more reserved symbols on which communication is not permitted). This allows transmissions from the base station (or from the UE) based on the first CP and the second CP, respectively, to be multiplexed and / or otherwise coexist in timeslots. In one example, base station 105 (e.g., via multiplexing component 240) may configure UE 115 to have one or more rules, or some indication of such rules (e.g., via RRC or higher-layer signaling), to ensure that UE 115 can also derive the second timeslot format based on the first timeslot format. In this example, the rules may be UE-specific, based on indicated UE capabilities (e.g., via RRC or higher-layer signaling), etc.

[0084] Refer again Figure 4 Optionally, at block 408, an indicator for the second time slot format can be transmitted. In one aspect, the time slot format export component 244 can transmit the indicator for the second time slot format, for example, in conjunction with processors 205, memory 202, transceiver 270, multiplexing component 240, etc. For example, the time slot format export component 244 can transmit the indicator for the second time slot format to one or more UEs 115 using an indicator in configuration or related signaling (such as in downlink control information (DCI) in a downlink control channel (e.g., PDCCH), a value map having values ​​indicating the communication direction of each symbol in the second time slot format, etc.

[0085] In method 400, at block 410, a first communication based on a first CP type and a second communication based on a second CP type can be multiplexed within a time slot. In one aspect, multiplexing component 240 can, for example, in conjunction with processor 205, memory 202, transceiver 270, etc., multiplex the first communication based on the first CP type and the second communication based on the second CP type within this time slot. As described, the first communication can be prepared for transmission based on a first time slot format and timeline associated with the first CP, such that the first communication can be prepared for transmission in symbols having an appropriate communication direction (e.g., a downlink for transmission at base station 105 or an uplink for transmission at UE 115). Similarly, the second communication can be prepared for transmission based on a second time slot format and timeline associated with the second CP, such that the second communication can be prepared for transmission in symbols having an appropriate communication direction (e.g., a downlink for transmission at base station 105 or an uplink for transmission at UE 115). The first and second communications can be multiplexed for transmission within the same time slot. In a specific example, the first and second communications may overlap in the time domain within a time slot, and their corresponding symbols may be associated with the same communication direction based on the defined time slot format.

[0086] In method 400, at block 412, within a time slot, a first communication may be transmitted based on a first timeline, and a second communication may be transmitted based on a second timeline. In one aspect, multiplexing component 240 may, for example, be integrated with processor 205, memory 202, transceiver 270, etc., to transmit the first communication based on the first timeline and the second communication based on the second timeline within the time slot. In this regard, the first and second communications may be transmitted in symbols of the first and second timelines, respectively, and the first and second timelines may appear within the same time slot. Additionally, as described, base station 105 may include components for additionally receiving, within a time slot, the multiplexed first communication (based on a first CP type) and the second communication (based on a second CP type) from UE 115.

[0087] In one example, transmitting the first and second communications at block 412 may optionally include defining one or more time slots between the first and second communications at block 414. In one aspect, multiplexing component 240 may define one or more time slots between the first and second communications, for example, in conjunction with processor 205, memory 202, transceiver 270, etc. For example, multiplexing component 240 may define one or more time slots during which communication may be prohibited, to align the first communication with a first timeline (e.g., with symbol boundaries of the first timeline) and / or to align the second communication with a second timeline (e.g., with symbol boundaries of the second timeline) to minimize the occurrence of conflicting symbol directions in the respective time slot formats. Figure 8An example is shown in the figure.

[0088] Figure 8 An example of timeline 800 for communication based on a first timeline for the normal CP type (including 14 OFDM symbols) and a second timeline for the extended CP type (including 12 OFDM symbols) is explained. In this example, after transmitting extended CP (ECP) control 802 and ECP data 804 in the first three symbols of the extended CP timeline, multiplexing component 240 may define a time gap (e.g., guard time 806) before transmitting normal CP (NCP) communication 808 to align communication 808 to the fifth symbol of the NCP timeline and NCP communication 810 to the seventh symbol. As shown, the time gap may include a share of OFDM symbols in one timeline or another to align with the boundary of the next OFDM symbol. Similarly, multiplexing component 240 may define a time gap (e.g., guard time 812) before transmitting additional ECP data 814 to align ECP data 814 to the tenth symbol of the ECP timeline.

[0089] Figure 5 A flowchart illustrating an example of a method 500 for receiving and / or decoding communications with different CP types (e.g., via a UE) is provided. In one example, the base station may also perform the functions described in method 500 and / or include... Figure 3 The corresponding components are used to receive and decode multiplexed communications with different CP types.

[0090] In method 500, optionally, at block 502, a first timeslot format indicator may be received. In one aspect, timeslot format determination component 342 may receive the first timeslot format indicator, for example, in conjunction with processor 305, memory 302, transceiver 370, communication component 340, etc. For example, timeslot format determination component 342 may receive the first timeslot format indicator from a configuration, receive the first timeslot format indicator in control channel communication (e.g., from base station 105), etc. In one example, as described, the indicator may be a value indicated in the configuration, where the value may correspond to a timeslot format defined in 5G NR (e.g., timeslot format 27 or 55, such as...). Figure 6 (As shown). In another example, the indicator may include a value map where each value indicates that the corresponding symbol in the time slot is downlink, uplink, flexible, etc. As described, the time slot format determination component 342 may receive or otherwise determine the indicator (e.g., in RRC signaling, dedicated control signaling, etc.) semi-statically, dynamically, etc., because the selected format may vary from UE to UE, from group to group, etc.

[0091] In method 500, optionally, at block 504, the first time slot format for the first CP type can be determined based on a first time slot format indicator. In one aspect, the time slot format determination component 342 can, for example, in conjunction with processors 305, memory 302, transceiver 370, communication component 340, etc., determine the first time slot format for the first CP type based on the first time slot format indicator. For example, the time slot format determination component 342 can determine the communication direction (e.g., downlink, uplink, flexible, etc.) of each symbol in the time slot based on the time slot format indicator. Additionally, in one example, the time slot format determination component 342 can determine the configuration for flexible symbols based on a separate configuration (e.g., from base station 105, etc.). The symbols can be aligned with a symbol grid corresponding to the first CP type (e.g., based on the number of symbols configured for the first CP type).

[0092] In method 500, optionally, at block 506, a second timeslot format can be exported. In one aspect, the timeslot format export component 344 can export the second timeslot format, for example, in conjunction with processor 305, memory 302, transceiver 370, communication component 340, etc. For example, the timeslot format export component 344 can be based on a first timeslot format (e.g., based on a reference format). Figure 6 and Figure 7 The second time slot format is derived using one or more rules described above. In one example, for this purpose, base station 105 and UE 115 may use the same or similar rule set (as described above) to derive the second time slot format based on the first time slot format to ensure that base station 105 and UE 115 derive the same time slot format. In one example, time slot format deriving component 344 may receive a rule set or some indication of the rule set from base station 105 (e.g., via RRC or higher-layer signaling). In one example, for this purpose, the rule set may be UE-specific and / or based on the indicated UE capabilities (e.g., indicated via RRC or higher-layer signaling). In another example, time slot format deriving component 344 may derive the second time slot format based on a separate time slot format indicator configured for the second time slot format (e.g., received in the configuration from base station 105, which may include values ​​indicating the format, a value map indicating the communication direction of each symbol in the time slot, etc.).

[0093] Furthermore, the first time slot format may relate to communication using a first CP type, and the second time slot format may relate to communication using a second CP type. Moreover, in this regard, the first time slot format may be based on a first timeline associated with the first CP type, and the second time slot format may be based on a second timeline associated with the second CP type, wherein the first and second timelines may differ based on having a different number of symbols per time slot. Symbols may be aligned with a symbol grid corresponding to the second CP type (e.g., based on the number of symbols configured for the second CP type). As described, the symbol grids for the first and second CP types may not be aligned within the time slot. In any case, the UE and the base station may communicate based on the determined symbol positions and communication directions.

[0094] For example, this could include receiving first communication at block 508 according to a first timeline and / or first timeslot format based on a first CP type. In one aspect, communication component 340 could, for example, in conjunction with processor 305, memory 302, transceiver 370, etc., receive first communication (e.g., transmission from base station 105) according to a first timeline and / or first timeslot format based on a first CP type (e.g., based on determining that a symbol is a downlink symbol for the first CP type). As described, the first timeslot format for the first CP type could include symbols having a specified communication direction, and communication component 340 could receive the first communication in symbols having an appropriate communication direction (e.g., a downlink for UE to receive signals or an uplink for base station to receive signals).

[0095] Communication based on the determined symbol position and communication direction may further include, at block 510, receiving second communication according to a second timeline and / or second timeslot format based on a second CP type, wherein the second communication is multiplexed with the first communication in the same time slot. In one aspect, communication component 340 may, for example, in conjunction with processor 305, memory 302, transceiver 370, etc., receive second communication (e.g., another transmission) according to a second timeline and / or second timeslot format based on a second CP type (e.g., based on determining that the symbol is a downlink symbol for the second CP type). The second communication may be multiplexed with the first communication in the same time slot (as described) and may therefore be transmitted in symbols of corresponding timelines that may have the same communication direction (e.g., a downlink for UE signal reception or an uplink for base station signal reception). As described, the second timeslot format for the second CP type may include symbols having a specified communication direction, which may overlap temporally with symbols of the first timeslot format having the same specified communication direction. Therefore, communication component 340 can receive first communication in a first symbol according to a first timeline and second communication in a second symbol according to a second timeline, which may have the same communication direction and / or may overlap in the time domain or otherwise overlap (e.g., downlink for UE to receive signals or uplink for base station to receive signals). In one example, communication component 340 can receive communication over one or more time slots (as referenced). Figure 8 The first and second communications described herein, wherein the one or more time slots may separate the communications so that the communications may be aligned with the appropriate symbol boundaries of their associated timelines as defined by their associated CP types. Additionally, as described, the UE 115 may include components for additionally transmitting the multiplexed first communications (based on the first CP type) and second communications (based on the second CP type) to the base station 105 within a time slot.

[0096] In method 500, at block 512, the first communication may be decoded based on a first length of a first CP type, and at block 514, the second communication may be decoded based on a second length of a second CP type. In one aspect, communication component 340 may, for example, decode the first communication based on the first length of a first CP type in conjunction with processor 305, memory 302, transceiver 370, etc., and may decode the second communication based on the second length of a second CP type. For example, communication component 340 may use an appropriate length of a given CP to verify a received signal and / or determine missing data from the beginning of the signal based on data at the end of the signal corresponding to the CP length.

[0097] Figure 9 This is a block diagram of a MIMO communication system 900, including base station 105 and UE 115. The MIMO communication system 900 can be explained in reference [reference needed]. Figure 1The wireless communication system 100 is described in various aspects. Base station 105 may be a reference. Figure 1-3 Examples of various aspects of the described base station 105 are provided. Base station 105 may be equipped with antennas 934 and 935, and UE 115 may be equipped with antennas 952 and 953. In the MIMO communication system 900, base station 105 can transmit data simultaneously on multiple communication links. Each communication link may be referred to as a "layer," and the "rank" of the communication link indicates the number of layers used for communication. For example, in a 2x2 MIMO communication system where base station 105 transmits two "layers," the rank of the communication link between base station 105 and UE 115 is 2.

[0098] At base station 105, transmit (Tx) processor 920 can receive data from a data source. Transmit processor 920 can process this data. Transmit processor 920 can also generate control symbols or reference symbols. Transmit MIMO processor 930 can perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, or reference symbols where applicable, and can provide the output symbol stream to transmit modulators / demodulators 932 and 933. Each modulator / demodulator 932 to 933 can process its respective output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator / demodulator 932 to 933 can further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a DL signal. In one example, the DL signal from modulators / demodulators 932 and 933 can be transmitted via antennas 934 and 935, respectively.

[0099] UE 115 can be used as a reference. Figure 1-3 Examples of various aspects of the described UE 115. At UE 115, UE antennas 952 and 953 can receive DL signals from base station 105 and can provide the received signals to modulators / demodulators 954 and 955, respectively. Each modulator / demodulator 954 to 955 can condition (e.g., filter, amplify, down-convert, and digitize) its respective received signal to obtain an input sample. Each modulator / demodulator 954 to 955 can further process the input sample (e.g., for OFDM, etc.) to obtain received symbols. MIMO detector 956 can obtain the received symbols from modulators / demodulators 954 and 955, perform MIMO detection on these received symbols where applicable, and provide detected symbols. Receive (Rx) processor 958 can process (e.g., demodulate, deinterleave, and decode) the detected symbols, provide the decoded data to UE 115 to a data output, and provide the decoded control information to processor 980 or memory 982.

[0100] In some cases, processor 980 may execute stored instructions to instantiate communication component 340 (e.g., see...). Figure 1 and 3 ).

[0101] On the uplink (UL), at UE 115, transmit processor 964 can receive and process data from a data source. Transmit processor 964 can also generate reference symbols for a reference signal. Symbols from transmit processor 964 can be pre-encoded by transmit MIMO processor 966 where applicable, further processed by modulators / demodulators 954 and 955 (e.g., for SC-FDMA, etc.), and transmitted to base station 105 according to communication parameters received from base station 105. At base station 105, UL signals from UE 115 can be received by antennas 934 and 935, processed by modulators / demodulators 932 and 933, detected by MIMO detector 936 where applicable, and further processed by receive processor 938. Receive processor 938 can provide decoded data to data output and processor 940 or memory 942.

[0102] In some cases, processor 940 may execute stored instructions to instantiate multiplexed component 240 (e.g., see [reference]). Figure 1 and 2 ).
