Abstract

Methods, systems, and devices for wireless communications are described. A communications device (also referred to as a user equipment (UE) or base station) may select a sequence from a set of sequences for communicating a payload including a set of bits. The length of the selected sequence may be based on the number of time periods used to communicate the payload and the number of frequency tones used to communicate the payload. The communications device may apply an interleaving function to the selected sequence to generate an interleaved sequence, and use the interleaved sequence to transmit the payload including the set of bits. Similarly, the communications device may receive the payload including the set of bits using the interleaved sequence, and apply an interleaving function to deinterleave the interleaved sequence to generate the selected sequence. The communications device may thereby decode the payload based on the selected sequence.

Technical Field

[0003] The following relates generally to wireless communications, and more particularly to sequence interleaving for communicating multi-bit payloads.

[0004] background

[0005] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcast, and the like. These systems may be able to support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth generation (4G) systems (such as long term evolution (LTE) systems, advanced LTE (LTE-A) systems, or LTE-A Pro systems), and fifth generation (5G) systems, which may be referred to as new radio (NR) systems. These systems may employ various technologies, such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM).

[0006] A wireless multiple-access communication system may include one or more base stations or one or more network access nodes, each of which simultaneously supports communication for multiple communication devices, which may also be referred to as user equipment (UE). Summary of the invention

[0007] Various aspects of the described technology relate to configuring a communication device (which may be additionally referred to as a user equipment (UE)) to support sequence-based wireless communication. In some cases, the UE may experience Doppler shift or delay spread, which may affect sequence-based wireless communication. In order to reduce or alleviate the impact of Doppler shift or delay spread on sequence-based wireless communication, the UE may be configured to provide sequence interleaving for sequence-based wireless communication. For example, the UE may be configured to select a sequence (e.g., an orthogonal sequence) to transmit information bits. The UE may apply an interleaving function to the selected sequence to generate an interleaved sequence, and use the interleaved sequence to transmit a payload including information bits. Similarly, a base station may use an interleaved sequence to receive a payload including information bits. The base station may apply an interleaving function to deinterleave the interleaved sequence to generate the selected sequence, and decode the payload based on the selected sequence. As a result, the UE may support higher reliability of sequence-based wireless communication in a wireless communication system that experiences Doppler shift, delay spread, or both.

[0046] A wireless communication system may include multiple communication devices, such as a UE and a base station (which may provide wireless communication services to the UE). For example, such a base station may be a next-generation B node or a gigabit B node (either of which may be referred to as a gNB) that may support multiple radio access technologies, including 4G systems (such as LTE systems) and 5G systems (which may be referred to as NR systems). Some wireless communication systems (such as 4G and 5G systems) may support sequence-based wireless communication between multiple communication devices (such as UEs and base stations). Examples of sequence-based wireless communication may use OFDM-based sequences, DFT-based sequences, and the like. Such sequences may have a time domain phase ramp attribute, a frequency domain phase ramp attribute, or both. Some wireless communication systems (such as 4G and 5G systems) may experience a Doppler effect, which may affect sequence-based wireless communication. Examples of the Doppler effect may include, for example, high Doppler spread, high delay spread, high Doppler shift, high delay shift, or a combination thereof. In some cases, the time domain phase ramp properties or frequency domain phase ramp properties of certain sequences may cause errors at the receiver due to corresponding time domain or frequency domain radio frequency propagation phenomena (e.g., Doppler shift or delay spread). As the demand for wireless communication efficiency increases, it may be desirable to provide improvements to sequence-based wireless communications to support higher reliability and lower latency, among other things.

[0047] The base station or UE or both may be configured to support sequence interleaving for sequence-based wireless communication to reduce or mitigate the Doppler effect on sequence-based wireless communication. For example, the base station or UE or both may be configured to provide sequence interleaving for sequence-based wireless communication to reduce or mitigate the effects of any combination of high Doppler spread, high delay spread, high Doppler frequency shift, high delay shift or radio frequency propagation phenomena. The base station or UE or both may select a sequence for conveying a payload including several bits from a set of sequences (e.g., orthogonal sequences). The length of the selected sequence may depend on the number of symbol periods used to convey the payload and the number of frequency modulations used to convey the payload. The base station or UE or both may apply an interleaving function to the selected sequence to generate an interleaved sequence.

[0048] Base station or UE or both can identify interleaving function based on the table that element index of selected sequence is mapped to element index of interleaved sequence.In some other examples, base station or UE or both can identify interleaving function based on equation that defines interleaving function.Base station or UE or both can use interleaved sequence to transmit payload including several bits thus.As a result, base station or UE or both can support higher reliability based on sequence wireless communication in wireless communication system experiencing high Doppler spread, high delay spread, high Doppler frequency shift, high delay shift or its combination.

[0049] Various aspects of the subject matter described in the present disclosure may be implemented to achieve one or more of the following potential advantages, among others. The techniques employed by the UE may provide benefits and enhancements to the operation of the UE. For example, the operations performed by the UE may provide improvements to sequence-based wireless communications. In some examples, configuring the UE to support sequence interleaving for sequence-based wireless communications may support improvements to power consumption, spectral efficiency, and in some examples, may promote enhanced efficiency for sequence-based wireless communications operations and other benefits.

[0050] Aspects of the present disclosure are initially described in the context of wireless communication systems. Aspects of the present disclosure are further illustrated and described by and with reference to apparatus diagrams, system diagrams, and flow diagrams related to sequence interleaving for communicating multi-bit payloads.

[0051] Figure 1 An example of a wireless communication system 100 supporting sequence interleaving for conveying multi-bit payloads according to various aspects of the present disclosure is illustrated. The wireless communication system 100 may include one or more base stations 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a long term evolution (LTE) network, an advanced LTE (LTE-A) network, an LTE-A Pro network, or a new radio (NR) network. In some examples, the wireless communication system 100 may support enhanced broadband communications, ultra-reliable (e.g., mission-critical) communications, low latency communications, communications with low-cost and low-complexity devices, or any combination thereof.

[0052] The base stations 105 may be dispersed throughout a geographic area to form the wireless communication system 100, and may be different forms of devices or devices with different capabilities. The base stations 105 and the UEs 115 may communicate wirelessly via one or more communication links 125. Each base station 105 may provide a coverage area 110 over which the UEs 115 and the base stations 105 may establish one or more communication links 125. The coverage area 110 may be an example of a geographic area over which the base stations 105 and the UEs 115 may support communication of signals according to one or more radio access technologies.

[0053] The UEs 115 may be dispersed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 may be stationary or mobile, or stationary and mobile at different times. The UEs 115 may be different forms of devices or devices with different capabilities. Figure 1Some example UEs 115 are illustrated in FIG. 1. The UEs 115 described herein may be capable of communicating with various types of devices, such as other UEs 115, base stations 105, or network equipment (e.g., core network nodes, relay devices, integrated access and backhaul (IAB) nodes, or other network equipment), such as Figure 1 as shown in .

[0054] Each base station 105 may communicate with the core network 130, or communicate with each other, or both. For example, the base station 105 may interface with the core network 130 via one or more backhaul links 120 (e.g., via S1, N2, N3 or other interfaces). The base stations 105 may communicate with each other directly (e.g., directly between the base stations 105), or indirectly (e.g., via the core network 130), or directly and indirectly on the backhaul link 120 (e.g., via X2, Xn or other interfaces). In some examples, the backhaul link 120 may be or include one or more wireless links. One or more of the base stations 105 described herein may include or may be referred to by a person of ordinary skill in the art as a base transceiver station, a radio base station, an access point, a radio transceiver, a B node, an evolved B node (eNB), a next generation B node or a gigabit B node (any of which may be referred to as a gNB), a home B node, a home evolved B node, or other suitable terms.

[0055] UE 115 may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable term, where "device" may also be referred to as a unit, a station, a terminal, or a client, etc. UE 115 may also include or may be referred to as a personal electronic device, such as a cellular phone, a personal digital assistant (PDA), a tablet computer, a laptop computer, or a personal computer. In some examples, UE 115 may include or be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communication (MTC) device, etc., which may be implemented in various objects such as appliances or vehicles, meters, etc. The UE 115 described herein may be able to communicate with various types of devices, such as other UEs 115 that may sometimes act as relays, as well as base stations 105 and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, relay base stations, etc., such as Figure 1 as shown in .

[0056] The UE 115 and the base station 105 may communicate wirelessly with each other via one or more communication links 125 on one or more carriers. The term "carrier" may refer to a set of radio frequency spectrum resources having a defined physical layer structure for supporting the communication link 125. For example, a carrier for the communication link 125 may include a portion of a radio frequency spectrum band (e.g., a bandwidth portion (BWP)) that operates according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling for coordinating carrier operations, user data, or other signaling. The wireless communication system 100 may support communication with the UE 115 using carrier aggregation or multi-carrier operation. The UE 115 may be configured to have multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation may be used in conjunction with both frequency division duplex (FDD) and time division duplex (TDD) component carriers.

[0057] In some examples (e.g., in a carrier aggregation configuration), a carrier may also have acquisition signaling or control signaling that coordinates the operation of other carriers. A carrier may be associated with a frequency channel (e.g., an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA) Absolute Radio Frequency Channel Number (EARFCN)) and may be located according to a channel grid for discovery by UE 115. A carrier may operate in a standalone mode in which initial acquisition and connection may be made by UE 115 via the carrier, or a carrier may operate in a non-standalone mode in which a connection is anchored using a different carrier (e.g., a different carrier of the same or different radio access technology).

[0058] The signal waveform transmitted on the carrier may include multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques, such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system using MCM technology, a resource element may include a code element period (e.g., the duration of a modulation code element) and a subcarrier, where the code element period and the subcarrier spacing are inversely related. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the code rate of the modulation scheme, or both). Thus, the more resource elements received by UE 115 and the higher the order of the modulation scheme, the higher the data rate of UE 115 can be. Wireless communication resources may refer to a combination of radio frequency spectrum resources, time resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers can further improve the data rate or data integrity of communication with UE 115.

[0059] One or more parameter designs for a carrier may be supported, where the parameter designs may include a subcarrier spacing (Δf) and a cyclic prefix. A carrier may be divided into one or more BWPs with the same or different parameter designs. In some examples, a UE 115 may be configured with multiple BWPs. In some examples, a single BWP for a carrier may be active at a given time, and communications for a UE 115 may be limited to the one or more active BWPs. The time interval of a base station 105 or a UE 115 may be expressed in multiples of a basic time unit, which may refer to, for example, a sampling period T s =1 / (Δf max ·Nf) seconds, where Δf max Nf may represent the maximum supported subcarrier spacing, and Nf may represent the maximum supported discrete Fourier transform (DFT) size. Time intervals of communication resources may be organized according to radio frames, each having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023).

[0060] Each frame may include a plurality of consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, a frame may be divided into subframes (e.g., in the time domain), and each subframe may be further divided into a number of time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include a number of code element periods (e.g., depending on the length of the cyclic prefix added before each code element period). In some wireless communication systems 100, the time slot may be further divided into a plurality of mini-time slots containing one or more code elements. Excluding the cyclic prefix, each code element period may include one or more (e.g., Nf) sampling periods. The duration of the code element period may depend on the subcarrier spacing or the operating frequency band. A subframe, a time slot, a mini-time slot or a code element may be the minimum scheduling unit of the wireless communication system 100 (e.g., in the time domain), and may be referred to as a transmission time interval (TTI). In some examples, the TTI duration (e.g., the number of code element periods in the TTI) may be variable. Additionally or alternatively, the minimum scheduling unit of the wireless communication system 100 may be dynamically selected (e.g., in bursts of shortened TTIs (sTTIs)).

[0061] Physical channels may be multiplexed on a carrier according to various techniques. Physical control channels and physical data channels may be multiplexed on a downlink carrier, for example, using one or more of a time division multiplexing (TDM) technique, a frequency division multiplexing (FDM) technique, or a hybrid TDM-FDM technique. A control region (e.g., a control resource set (CORESET)) for a physical control channel may be defined by a number of symbol periods and may extend across a system bandwidth or a subset of a system bandwidth of a carrier. One or more control regions (e.g., CORESETs) may be configured for a set of UEs 115. For example, one or more of the UEs 115 may monitor or search a control region for control information according to one or more search space sets, and each search space set may include one or more control channel candidates in one or more aggregation levels arranged in a cascaded manner. An aggregation level for a control channel candidate may refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with coded information for a control information format having a given payload size. The search space sets may include a common search space set configured for transmitting control information to multiple UEs 115 and a UE-specific search space set for transmitting control information to a specific UE 115 .

[0062] Each base station 105 may provide communication coverage via one or more cells (e.g., macro cells, small cells, hot spots, or other types of cells, or any combination thereof). The term "cell" may refer to a logical communication entity used to communicate with a base station 105 (e.g., on a carrier), and may be associated with an identifier (e.g., a physical cell identifier (PCID), a virtual cell identifier (VCID), or other) used to distinguish adjacent cells. In some examples, a cell may also refer to a geographic coverage area 110 or a portion of a geographic coverage area 110 (e.g., a sector) on which a logical communication entity operates. The range of such a cell may range from a smaller area (e.g., a structure, a subset of a structure) to a larger area depending on various factors (such as the capabilities of the base station 105). For example, a cell may be or include a building, a subset of a building, or an external space between or overlapping a geographic coverage area 110, as well as other examples.

[0063] A macro cell generally covers a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access to UEs 115 that have service subscriptions with a network provider that supports the macro cell. A small cell may be associated with a lower power base station 105 (compared to a macro cell), and the small cell may operate in the same or different (e.g., licensed, unlicensed) frequency band as the macro cell. A small cell may provide unrestricted access to UEs 115 that have service subscriptions with a network provider, or may provide restricted access to UEs 115 associated with the small cell (e.g., UEs 115 in a closed subscriber group (CSG), UEs 115 associated with users in a home or office). A base station 105 may support one or more cells and may also support communications on one or more cells using one or more component carriers.

[0064] In some examples, base stations 105 may be mobile and thus provide communication coverage for mobile geographic coverage areas 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, but the different geographic coverage areas 110 may be supported by the same base station 105. In other examples, overlapping geographic coverage areas 110 associated with different technologies may be supported by different base stations 105. The wireless communication system 100 may include, for example, a heterogeneous network in which different types of base stations 105 provide coverage for various geographic coverage areas 110 using the same or different radio access technologies.

[0065] The wireless communication system 100 may support synchronous or asynchronous operation. For synchronous operation, the base stations 105 may have similar frame timing, and transmissions from different base stations 105 may be approximately aligned in time. For asynchronous operation, the base stations 105 may have different frame timing, and transmissions from different base stations 105 may not be aligned in time in some examples. The techniques described herein may be used for synchronous or asynchronous operation.

[0066] Some UEs 115 may be configured to employ a reduced power consumption mode of operation, such as half-duplex communication (e.g., a mode that supports unidirectional communication via transmission or reception but not simultaneous transmission and reception). In some examples, half-duplex communication may be performed with a reduced peak rate. Other power saving techniques for UE 115 include entering a power saving deep sleep mode when not engaged in active communications, operating on a limited bandwidth (e.g., according to narrowband communications), or a combination of these techniques. For example, some UEs 115 may be configured to operate using a narrowband protocol type that is associated with a defined portion or range (e.g., a subcarrier or resource block (RB) set) within a carrier, within a guard band of a carrier, or outside a carrier.

[0067] The wireless communication system 100 may be configured to support ultra-reliable communication or low latency communication or various combinations thereof. For example, the wireless communication system 100 may be configured to support ultra-reliable low latency communication (URLLC) or mission-critical communication. UE 115 may be designed to support ultra-reliable, low latency or critical functions (e.g., mission-critical functions). Ultra-reliable communication may include private communication or group communication, and may be supported by one or more mission-critical services (such as mission-critical push-to-talk (MCPTT), mission-critical video (MCVideo), or mission-critical data (MCData). Support for mission-critical functions may include prioritization of services, and mission-critical services may be used for public safety or general commercial applications. The terms ultra-reliable, low latency, critical mission, and ultra-reliable low latency may be used interchangeably herein.

[0068] In some examples, UE 115 may also be able to communicate directly with other UE 115 over a device-to-device (D2D) communication link 135 (e.g., using a peer-to-peer (P2P) or D2D protocol). One or more UEs 115 utilizing D2D communication may be within a geographic coverage area 110 of a base station 105. Other UEs 115 in such a group may be outside the geographic coverage area 110 of the base station 105, or may not be able to receive transmissions from the base station 105 for other reasons. In some examples, each group of UEs 115 communicating via D2D communication may utilize a one-to-many (1:M) system, in which each UE 115 transmits to each other UE 115 in the group. In some examples, the base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication is performed between UEs 115 without involving the base station 105.

[0069] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC) or a 5G core (5GC), and the EPC or 5GC may include at least one control plane entity (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) for managing access and mobility, and at least one user plane entity (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)) for routing packets or interconnecting to an external network. The control plane entity may manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management of UE 115 served by a base station 105 associated with the core network 130. User IP packets may be delivered via a user plane entity, which may provide IP address allocation and other functions. The user plane entity may be connected to a network operator IP service 150. Operator IP services 150 may include access to the Internet, an intranet, an IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0070] Some network devices (such as base stations 105) may include subcomponents, such as access network entities 140, which may be examples of access node controllers (ANCs). Each access network entity 140 may communicate with each UE 115 through one or more other access network transport entities 145, which may be referred to as radio heads, smart radio heads, or transmission / reception points (TRPs). Each access network transport entity 145 may include one or more antenna panels. In some configurations, the various functions of each access network entity 140 or base station 105 may be distributed across various network devices (e.g., radio heads and ANCs) or merged into a single network device (e.g., base station 105).

[0071] The wireless communication system 100 may operate using one or more frequency bands, typically in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). In general, the 300 MHz to 3 GHz region is referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelengths range from about 1 decimeter to 1 meter long. UHF waves may be blocked or redirected by buildings and environmental features, but these waves may penetrate various structures sufficiently for macro cells to provide service to UEs 115 located indoors. Transmissions using UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than 100 kilometers) than transmissions using smaller frequencies and longer waves in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0072] The wireless communication system 100 may also operate in a super high frequency (SHF) zone using a frequency band from 3 GHz to 30 GHz (also known as a centimeter band) or in an extremely high frequency (EHF) zone of a spectrum (e.g., from 30 GHz to 300 GHz) (also known as a millimeter band). In some examples, the wireless communication system 100 may support millimeter wave (mmW) communications between UE 115 and base station 105, and the EHF antenna of the corresponding device may be smaller and more closely spaced than the UHF antenna. In some examples, this may facilitate the use of antenna arrays within the device. However, the propagation of EHF transmissions may be subject to even greater atmospheric attenuation and a shorter range than SHF or UHF transmissions. The technology disclosed herein may be adopted across transmissions using one or more different frequency zones, and the use of frequency bands specified across these frequency zones may vary by country or regulatory agency.

[0073] The wireless communication system 100 may utilize both licensed and unlicensed radio frequency spectrum bands. For example, the wireless communication system 100 may employ licensed assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology in an unlicensed band (such as the 5 GHz industrial, scientific, and medical (ISM) band). When operating in an unlicensed radio frequency spectrum band, devices (such as base stations 105 and UEs 115) may employ carrier sensing for conflict detection and avoidance. In some examples, operations in an unlicensed band may be based on a carrier aggregation configuration (e.g., LAA) in coordination with component carriers operating in a licensed band. Operations in an unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among others.

[0074] The base station 105 or UE 115 may be equipped with multiple antennas, which can be used to employ technologies such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of the base station 105 or UE 115 may be located in one or more antenna arrays or antenna panels that can support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly (such as an antenna tower). In some examples, the antennas or antenna arrays associated with the base station 105 may be located at different geographical locations. The base station 105 may have an antenna array having antenna ports of several rows and columns that the base station 105 can use to support beamforming for communications with the UE 115. Similarly, the UE 115 may have one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support radio frequency beamforming for signals transmitted via the antenna ports.

[0075] The base station 105 or UE 115 can use MIMO communication to utilize multipath signal propagation and improve spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such technology may be referred to as spatial multiplexing. For example, the transmitting device may transmit multiple signals via different antennas or different antenna combinations. Similarly, the receiving device may receive multiple signals via different antennas or different antenna combinations. Each of the multiple signals may be referred to as a separate spatial stream and may carry bits associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers may be associated with different antenna ports for channel measurement and reporting. MIMO technology includes single-user MIMO (SU-MIMO), in which multiple spatial layers are transmitted to the same receiving device; and multi-user MIMO (MU-MIMO), in which multiple spatial layers are transmitted to multiple devices.

[0076] Beamforming (which may also be referred to as spatial filtering, directional transmission, or directional reception) is a signal processing technique that may be used at a transmitting device or a receiving device (e.g., a base station 105, a UE 115) to shape or steer an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be achieved by combining signals communicated via antenna elements of an antenna array so that some signals propagating at a particular orientation relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to signals communicated via antenna elements may include the transmitting device or the receiving device applying an amplitude offset, a phase offset, or both to signals carried via antenna elements associated with the device. Adjustments associated with each antenna element may be defined by a set of beamforming weights associated with a particular orientation (e.g., relative to the antenna array of the transmitting device or the receiving device, or relative to some other orientation).

[0077] The base station 105 or the UE 115 may use beam sweeping techniques as part of a beamforming operation. For example, the base station 105 may use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communication with the UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted multiple times by the base station 105 in different directions. For example, the base station 105 may transmit signals according to different sets of beamforming weights associated with different transmission directions. Transmissions in different beam directions may be used (e.g., by a transmitting device (such as the base station 105) or a receiving device (such as the UE 115)) to identify a beam direction used by the base station 105 for later transmission or reception.

[0078] Some signals, such as data signals associated with a particular recipient device, may be transmitted by base station 105 in a single beam direction, e.g., a direction associated with a recipient device, such as UE 115. In some examples, a beam direction associated with transmissions along a single beam direction may be determined based on signals transmitted in one or more beam directions. For example, UE 115 may receive one or more signals transmitted by base station 105 in different directions and may report to base station 105 an indication of the signal received by UE 115 with the highest signal quality or other acceptable signal quality.

[0079] In some examples, transmission by a device (e.g., by a base station 105 or a UE 115) may be performed using multiple beam directions, and the device may use a combination of digital precoding or radio frequency beamforming to generate a combined beam for transmission (e.g., from the base station 105 to the UE 115). The UE 115 may report feedback indicating precoding weights for one or more beam directions, and the feedback may correspond to a configured number of beams across the system bandwidth or one or more subbands. The base station 105 may transmit a reference signal that may be precoded or unprecoded (e.g., a cell-specific reference signal (CRS), a channel state information reference signal (CSI-RS)). The UE 115 may provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., a multi-panel type codebook, a linear combination type codebook, a port selection type codebook). Although these techniques are described with reference to signals transmitted by base station 105 in one or more directions, UE 115 may use similar techniques to transmit signals multiple times in different directions (e.g., to identify a beam direction for subsequent transmission or reception by UE 115) or to transmit signals in a single direction (e.g., to transmit data to a receiving device).

[0080] A receiving device (e.g., UE 115) may try multiple reception configurations (e.g., directional listening) when receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from a base station 105. For example, the receiving device may try multiple reception directions by receiving via different antenna subarrays, processing received signals according to different antenna subarrays, receiving according to different receive beamforming weight sets (e.g., different directional listening weight sets) applied to signals received at multiple antenna elements of an antenna array, or processing received signals according to different receive beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, any of which may be referred to as "listening according to different reception configurations or reception directions." In some examples, the receiving device may use a single reception configuration to receive along a single beam direction (e.g., when receiving a data signal). The single reception configuration may be aligned on a beam direction determined based on listening according to different reception configuration directions (e.g., a beam direction determined to have the highest signal strength, the highest signal-to-noise ratio (SNR), or other acceptable signal quality based on listening according to multiple beam directions).

[0081] The wireless communication system 100 may be a packet-based network that operates according to a layered protocol stack. In the user plane, the communication of the bearer or packet data convergence protocol (PDCP) layer may be IP-based. The radio link control (RLC) layer may perform packet segmentation and reassembly to communicate on a logical channel. The media access control (MAC) layer may perform priority handling and multiplex logical channels into transport channels. The MAC layer may also use error detection techniques, error correction techniques, or both to support retransmission of the MAC layer to improve link efficiency. In the control plane, the radio resource control (RRC) protocol layer may provide the establishment, configuration, and maintenance of an RRC connection that supports radio bearers of user plane data between UE 115 and base station 105 or core network 130. In the physical layer, transport channels may be mapped to physical channels.

[0082] UE 115 and base station 105 may support retransmission of data to increase the likelihood that the data is successfully received. Hybrid automatic repeat request (HARQ) feedback is a technique for increasing the likelihood that data is correctly received on communication link 125. HARQ may include a combination of error detection (e.g., using a cyclic redundancy check (CRC)), forward error correction (FEC), and retransmission (e.g., automatic repeat request (ARQ)). HARQ may improve the throughput of the MAC layer in poor radio conditions (e.g., low signal-to-noise ratio conditions). In some examples, a device may support simultaneous slot HARQ feedback, wherein the device may provide HARQ feedback in a specific time slot for data received in a previous symbol in the time slot. In other cases, the device may provide HARQ feedback in a subsequent time slot or according to some other time interval.

[0083] The base station 105 or UE 115 or both may be configured to support sequence interleaving for sequence-based wireless communication to counter high Doppler spread, high delay spread, high Doppler shift, high delay shift or a combination thereof. For example, the base station 105 or UE 115 or both may select a sequence for conveying a payload including several bits from a set of sequences (e.g., orthogonal sequences). For example, the base station 105 or UE 115 or both may be configured to use an orthogonal sequence to transmit and receive a signal including a payload (e.g., a multi-bit payload). In some examples, the base station 105 or UE 115 or both may generate or be configured with an orthogonal sequence set, which may be equivalently referred to as an orthogonal code point set. Orthogonal sequences may be orthogonal in the time domain, the frequency domain, or both. The number of orthogonal sequences in the orthogonal sequence set may be based on the number of time periods such as orthogonal frequency division multiplexing (OFDM) symbols and the number of frequency tones such as the number of subcarriers, which are allocated for transmitting the payload of the signal.

[0084] For example, the base station 105 or the UE 115 or both may determine resource allocations for N OFDM symbols and M frequency tones, and may determine N×M orthogonal sequences accordingly. The base station 105 or the UE 115 or both may select an orthogonal sequence based on the size of the payload (e.g., the number of bits in the payload). For example, the base station 105 or the UE 115 or both may identify that the payload includes several bits, and may select several orthogonal sequences from a set of orthogonal sequences based on the number of bits. In some other examples, the base station 105 or the UE 115 or both may construct a codebook including orthogonal sequences. In the case where the codebook is constructed by the base station 105, the base station 105 may signal the constructed codebook to the UE 115.

[0085] Base station 105 or UE 115 or both can apply interleaving function to selected sequence to generate interleaved sequence in some examples.Base station 105 or UE 115 or both can identify the interleaving function based on the table of element index of the element index of the interleaved sequence mapped to.In some other examples, base station 105 or UE 115 or both can identify the interleaving function based on the equation defining the interleaving function.Base station 105 or UE 115 or both can use the interleaved sequence to transmit the payload including the several bits.As a result, when wireless communication system 100 experiences high Doppler spread, high delay spread, high Doppler frequency shift, high delay shift or its combination, base station 105 or UE 115 or both can support higher reliability based on sequence wireless communication.

[0086] Figure 2An example of a wireless communication system 200 that supports sequence interleaving for conveying multi-bit payloads according to various aspects of the present disclosure is illustrated. The wireless communication system 200 can support a variety of radio access technologies, including 4G systems (such as LTE systems, LTE-A systems, or LTE-A Pro systems), and 5G systems (which can be referred to as NR systems). In some examples, the wireless communication system 200 can implement aspects of the wireless communication system 100. For example, the wireless communication system 200 can support sequence-based wireless communication 205 between the base station 105 and the UE 115, which can be referenced Figure 1 Examples of corresponding devices described. The wireless communication system 200 can support improvements in power consumption and, in some examples, can facilitate higher reliability and lower latency for sequence-based wireless communications 205, among other benefits.

[0087] The base station 105 and the UE 115 may be configured with multiple antennas, which may be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output communications, or beamforming, or any combination thereof. The antennas of the base station 105 and the UE 115 may be located within one or more antenna arrays or antenna panels that may support multiple-input multiple-output operations or transmit or receive beamforming. For example, the antennas or antenna arrays associated with the base station 105 may be co-located at an antenna assembly such as an antenna tower. The base station 105 may have an antenna array having several rows and columns of antenna ports that the base station 105 may use to support beamforming for directional communications with the UE 115. Similarly, the UE 115 may have one or more antenna arrays that may support various multiple-input multiple-output or beamforming operations. Additionally or alternatively, the antenna panel may support radio frequency beamforming for signals transmitted via one or more antenna ports.

[0088] The base station 105 and the UE 115 may be configured to use multiple antennas to provide sequence-based wireless communication 205. The sequence-based wireless communication 205 may use orthogonal sequences, non-orthogonal sequences, etc. In some examples, the base station 105 and the UE 115 may be configured to use sequence-based wireless communication 205 to communicate various types of communications (e.g., control information, data) between the base station 105 and the UE 115. In other words, the wireless communication system 200 may support sequence-based wireless communication 205 to communicate various types of communications (e.g., control information, data) between a transmitter (e.g., a transmitter of the base station 105 or the UE 115) and a receiver (e.g., a receiver of the base station 105 or the UE 115).

[0089] exist Figure 2In an example of, sequence-based wireless communication 205 may include payload 210. Payload 210 may occupy a resource allocation of a resource grid. The resource grid may be based on the configuration of base station 105 and implemented by UE 115. For example, the resource grid may be applicable to an implementation or instance when UE 115 is configured to support sequence-based wireless communication with base station 105, or vice versa. The resource grid may include frequency and time resources across frequency domain and time domain. Frequency and time resources may include several subcarriers (e.g., several frequency tones) and several time periods (e.g., several symbols, such as OFDM symbols). Payload 210 may thus occupy a resource allocation of N OFDM symbols 215 and M frequency tones 220, and UE 115 may convey payload 210 using a sequence based on N OFDM symbols 215 and M frequency tones 220.

[0090] As described herein, N may correspond to any number, but may sometimes be defined within a range of 1 to 14. Similarly, M may correspond to any number, but may sometimes be defined within a range of 1 to 12. In some cases, such as when N=14 and M=12, the resource allocation may be a resource block. Payload 210 may be an example of any signal that includes information (e.g., a number of bits). For example, base station 105 may transmit a downlink signal that includes payload 210, or UE 115 may transmit an uplink signal that includes payload 210. For example, payload 210 may be an example of downlink control information (DCI), and accordingly, base station 105 may transmit payload 210 in a resource allocation of a physical downlink control channel (PDCCH). Likewise, payload 210 may be an example of uplink control information (UCI), and accordingly, UE 115 may transmit payload 210 in a resource allocation of a physical uplink control channel (PUCCH).

[0091] In some cases, the base station 105 and the UE 115 may experience radio frequency propagation phenomena such as high Doppler spread or high delay spread or both in the wireless communication system 200. Due to the high Doppler or large delay spread, the Doppler effect or delay spread may affect the sequence-based wireless communication between the base station 105 and the UE 115. In some cases, the base station 105 or the UE 115 or both may use an orthogonal sequence or a non-orthogonal sequence to convey the payload 210. For example, the base station 105 or the UE 115 or both may generate or configure a codebook of orthogonal sequences or non-orthogonal sequences, and the base station 105 or the UE 115 or both may select an orthogonal sequence or a non-orthogonal sequence from the codebook to convey the payload 210. The orthogonal or non-orthogonal sequence may have certain properties that increase the negative effects of Doppler shift or delay spread. For example, the sequence of the codebook may exhibit a time domain phase slope, a frequency domain phase slope, or both. In some cases, however, such use of orthogonal sequences or non-orthogonal sequences may not mitigate the effects of the Doppler effect (e.g., high Doppler spread, high delay spread, high Doppler shift, high delay shift, or a combination thereof) in the wireless communication system 200, which may reduce the likelihood of successful communication between the base station 105 or the UE 115.

[0092] The base stations 105 and UEs 115 may thus be configured to support operations for managing or improving sequence-based wireless communications to combat high Doppler spread, high delay spread, high Doppler shift, high delay shift, or a combination thereof in the wireless communication system 200. Additionally, the base stations 105 and UEs 115 in the wireless communication system 200 may support operations to conserve resources (e.g., time and frequency resources of the wireless communication system 200), battery life of the UEs 115, etc. For example, the base station 105 or the UE 115 or both may identify a number of bits (e.g., K bits) associated with the payload 210 and may generate a sequence set based in part on the number of bits.

[0093] For example, the base station 105 or the UE 115 or both may communicate via a resource allocation of a communication channel, and the base station 105 or the UE 115 or both may generate a number of orthogonal sequences (or non-orthogonal sequences) based on the resource allocation. For example, the base station 105 may allocate N OFDM symbols 215 and M frequency modulations 220 for transmission of the payload 210, and accordingly, the base station or the UE 115 or both may generate a number of orthogonal sequences equal to N×M. In some examples, each orthogonal sequence in the set of orthogonal sequences may have a length equal to the size of the resource allocation (e.g., the number of resource elements in the resource allocation, or N×M) so that each orthogonal sequence (or non-orthogonal sequence) may convey the payload 210 across the resource allocation. The base station 105 or the UE 115 or both may generate a set of N×M orthogonal sequences, and each orthogonal sequence may be associated with a length of N*M. Generation of orthogonal sequences with reference to Figure 3A and Figure 3B Describe in more detail.

[0094] The base station 105 or the UE 115 or both may determine a set of orthogonal sequences (or non-orthogonal sequences) based on the payload 210. For example, the base station 105 or the UE 115 or both may determine the size of the payload 210 (e.g., the number of bits included in the payload 210) and may determine the set of orthogonal sequences based on the size of the payload 210. For example, the payload 210 may include a number of bits equal to K, and accordingly, the number of orthogonal sequences within the determined set may be based on the value of K. In some examples, the base station 105 or the UE 115 or both may select a set of orthogonal sequences equal to 2 based on identifying that the payload 210 includes K bits. K In some examples, the base station 105 or the UE 115 or both may select 2 K orthogonal sequences, because 2 K The orthogonal sequences can provide a sequence for each possible value (ie, permutation) of the K bits.

[0095] UE 115 may identify an orthogonal sequence set (e.g., 2 KThe base station 105 may generate an orthogonal sequence set (orthogonal sequences), from which the UE 115 may select an orthogonal sequence to convey the payload 210. In the case where the base station 105 generates an orthogonal sequence set, the base station 105 may signal an indication of the orthogonal sequence set to the UE 115, and the UE 115 may construct a codebook including the indicated orthogonal sequence set. Alternatively, in the case where the UE 115 or both the base station 105 and the UE 115 generate an orthogonal sequence set, the UE 115 may construct a codebook including the orthogonal sequence set without additional signaling from the base station 105. In some examples, the UE 115 may construct the codebook so that each orthogonal sequence in the orthogonal sequence set in the codebook is associated with an index in the codebook. The base station 105 or the UE 115 or both may select an orthogonal sequence from the orthogonal sequence set (e.g., from the constructed codebook) based on the bits in the payload 210 to convey the payload 210.

[0096] In order to manage or improve sequence-based wireless communications while combating high Doppler spread, high delay spread, high Doppler frequency shift, high delay shift, or a combination thereof, the base station 105 or the UE 115 or both may apply an interleaving function to the generated orthogonal sequence (or the selected orthogonal sequence or non-orthogonal sequence). In some examples, the base station 105 or the UE 115 or both may use a nonlinear interleaving function. The generated orthogonal sequence (or the selected orthogonal sequence) may be represented as a=[a0,…,a K-1 ], where a corresponds to the value of a bit, and K is equal to the number of bits in the payload 210. The base station 105 or the UE 115 or both may apply an interleaving function to the generated orthogonal sequence (or the selected orthogonal sequence) a=[a0, ..., a K-1 ] to generate the expression b=[b0,…,b K-1 ], where b corresponds to the bit value and K is equal to the number of bits in the payload 210.

[0097] Base station 105 or UE 115 or both may identify the interleaving function based in part on a table or equation defining the interleaving function. In some examples, the interleaving function may be a second-order or higher-order polynomial equation. For example, the interleaving function may be defined by equation (1):

[0098] b i =a π(i) (1)

[0099] Where π(i) is a permutation or interleaving function π(·): {0, ..., K-1} → {0, ..., K-1}. Thus, the base station 105 or the UE 115 or both may generate an interleaved sequence b = [b0, ..., b k-1 ]. In some examples, the interleaving function may be a quadratic equation of length n as defined by equation (2):

[0100] Π(i)=(a0+a1i+a2i 2 )mod n (2)

[0101] Where a0, a1, a2 are selected so that Π(·) forms a permutation function. Alternatively, the interleaving function of length n may be defined by a table, such as the example Table 1 below. Each element index in the generated sequence may be mapped to an element index of the interleaved sequence in Table 1. Alternatively, UE 115 may receive signaling indicating the interleaving function for conveying payload 210. For example, UE 115 may receive configuration signaling from base station 105 to configure the interleaving for conveying payload 210.

[0102] Table 1 – Interleaving sequence of length 12

[0103] i Π(i) i Π(i) 0 0 6 2 1 9 7 6 2 4 8 5 3 3 9 10 4 1 10 7 5 8 11 1l

[0104] The configuration signaling may include a configuration message. The configuration message may be an RRC message. The base station 105 may enable and disable interleaving for conveying the payload 210 via an RRC message. For example, if the UE 115 receives a configuration message (e.g., an RRC message) including an indication that interleaving is enabled, the UE 115 may perform interleaving for conveying the payload 210 (e.g., enable the interleaver of the UE 115). Otherwise, the UE 115 may not perform (e.g., suppress execution) interleaving for conveying the payload 210 (e.g., disable the interleaver of the UE 115). In some examples, the configuration message (e.g., an RRC message) may include an indication that interleaving is disabled, and thereby the UE 115 may not perform (e.g., suppress execution) interleaving for conveying the payload 210 (e.g., disable the interleaver of the UE 115). In some other examples, the UE 115 may not perform (e.g., suppress execution) interleaving for conveying the payload 210 (e.g., disable the interleaver of the UE 115) based on the absence of the configuration message. That is, base station 105 may not transmit configuration signaling to UE 115, and based on not receiving the configuration signaling, UE 115 may determine that the interleaver of UE 115 is to be disabled.

[0105] In some examples, the base station 105 or the UE 115 or both may generate an orthogonal sequence based on the generated orthogonal sequence or the generated non-orthogonal sequence a=[a0, ..., a K-1 ] to generate a virtual matrix having a number of rows equal to the number of frequency tones used to convey the payload 210 and a number of columns equal to the number of symbols used to convey the payload 210. The base station 105 or the UE 115 or both may apply an interleaving function to the generated orthogonal sequence a=[a0, ..., a K-1] elements or values ​​within a column of the virtual matrix, where the length of the interleaving function is based on the number of frequency tones used to convey the payload 210.

[0106] In some examples, the base station 105 or the UE 115 or both may apply an interleaving function to the generated orthogonal sequence a=[a0, ..., a K-1 ] values ​​within the rows of the virtual matrix. In other examples, the base station 105 or the UE 115 or both may apply an interleaving function to the generated orthogonal sequence a=[a0, ..., a K-1 ] in the row of the virtual matrix and the generated orthogonal sequence a = [a0, ..., a K-1 ] is the value in the column of the virtual matrix. The interleaved reference of the generated orthogonal sequence Figure 4 Describe in more detail.

[0107] The base station 105 or the UE 115 or both may apply the permutation or interleaving in the frequency domain (e.g., on subcarriers in the frequency domain). In some other examples, the base station 105 or the UE 115 or both may apply the permutation or interleaving in the time domain (e.g., on OFDM symbols in the time domain). In other examples, the base station 105 or the UE 115 or both may apply the permutation or interleaving in both the frequency domain (e.g., on subcarriers in the frequency domain) and the time domain (e.g., on OFDM symbols in the time domain).

[0108] Base station 105 and UE 115 can thereby experience improvements to sequence-based wireless communications by supporting interleaving and permutation of sequences (e.g., orthogonal sequences). In some examples, configuring base station 105 and UE 115 to support uplink sequence-based wireless communications can support improvements to spectral efficiency and, in some examples, can promote higher reliability and lower latency for sequence-based wireless communications operations, among other benefits.

[0109] Figure 3A An example orthogonal matrix 300 - a that supports sequence interleaving for conveying multi-bit payloads in accordance with aspects of the present disclosure is illustrated. Figure 3B An example base sequence 300-b supporting sequence interleaving for communicating a multi-bit payload in accordance with aspects of the present disclosure is illustrated. In some examples, the orthogonal matrix 300-a and the base sequence 300-b may be implemented to implement aspects of the wireless communication system 100 and the wireless communication system 200. For example, the UE 115 or the base station 105 or both may use the orthogonal matrix 300-a and the base sequence 300-b to generate an orthogonal sequence set from which the UE 115 may select an orthogonal sequence to communicate a payload to the base station 105. The base station 105 and the UE 115 may be examples of corresponding devices as described herein.

[0110] The orthogonal matrix 300-a (which may be referred to as W) may be an orthogonal square matrix of size N (i.e., an N×N matrix). In some implementations, N may be equal to the number of symbols of the resource allocation associated with the transmission of the payload, as described with reference to Figure 2 Further, in some specific examples, the orthogonal matrix 300-a may be a discrete Fourier transform (DFT) matrix, and thus may be equivalently referred to as a DFT matrix. Accordingly, the rows or columns (eg, vectors) of the orthogonal matrix 300-a may be referred to as or Where n is the index of a row or column (e.g., the nth row or column) of the orthogonal matrix 300-a. Figure 3A It is explained that n=1, but n can be equal to any number n=0, 1, 2, ..., N-1.

[0111] The rows of the orthogonal matrix 300 - a may be defined by equation (3) shown below.

[0112]

[0113] The corresponding column of the orthogonal matrix 300-a may be equal to In equation (3), ω can be defined as ω = e -j2π / N Or ω=e j2π / N .vector Each column (or vector Each row of the orthogonal matrix 300-a may correspond to an OFDM symbol index i, where i=0 in the first column (e.g., the leftmost column) of the orthogonal matrix 300-a and increments by 1 until i=N-1 in the last column (e.g., the rightmost column) of the orthogonal matrix 300-a. In some cases, the OFDM symbol index i may correspond to an OFDM symbol of resource allocation that the UE 115 can use to transmit the payload. In some cases, the phase slope of a row or column of the orthogonal matrix 300-a may be defined as i*n, where i is the OFDM symbol index and n may describe the slope of the phase change. Thus, a column or row of the orthogonal matrix 300-a may include an entry for each OFDM symbol of resource allocation in one frequency modulation.

[0114] Base sequence 300-b (which may be equivalently referred to as base sequence ) may be a frequency domain base sequence of a cyclic shift. In other words, the base sequence 300-b may be a frequency domain base sequence S associated with a cyclic shift in the time domain. As such, the base sequence S may be based on a cyclic shift index m, where m=0, 1, 2, ..., M-1. In some aspects, M may be equal to the number of frequency tones of a resource allocation associated with the transmission of the payload, as described with reference to Figure 2 Equivalently, the base sequence S can be associated with a phase ramp vector in the frequency domain, such as e-j2πlm / M or e j2πlm / M , and the phase ramp vector and the basis sequence S can be multiplied together to determine the basis sequence As shown by base sequence 300-b.

[0115] For example, the base station 105 or the UE 115 or both may perform a DFT or a fast Fourier transform (FFT) on the base sequence S in the frequency domain to convert the base sequence S to the time domain, where in the time domain representation of the base sequence S (which may be referred to as ) has a length of M. The base station 105 or the UE 115 or both may apply the cyclic shift index m to To shift by index m It can effectively cycle The entries of are shifted forward or backward by m. The time domain cyclic shift can correspond to the frequency domain phase ramp vector e -j2πlm / M or e j2πlm / M . The index m of the phase ramp may correspond to the slope of the phase ramp (e.g., the phase ramp may be defined as m / M), and the index l may correspond to the frequency tone index of the resource allocation. As shown in the base sequence 300-b, S(0), S(1), S(2), ...S(l), ...S(M-1) may correspond to entries of the base sequence S for each frequency tone l=0, 1, 2, ..., M-1. Accordingly, the base sequence 300-b may include an entry for each frequency tone of the resource allocation in one OFDM codeword. In some cases, the base sequence 300-b may be a cell-specific base sequence so that each UE 115 within a cell of the base station 105 (e.g., within the geographic coverage area of ​​the base station 105) can use the same base sequence 300-b. Further, in some cases, the base sequence 300-b may have a low peak-to-average power ratio (PAPR) attribute and may be referred to as a low PAPR sequence.

[0116] like Figure 3B As illustrated, the base sequence 300-b may be a vector of size M×1. Additionally, the number of base sequences 300-b may be equal to the number of cyclic shift indices associated with the base sequences 300-b. For example, there may be M base sequences 300-b (e.g., one base sequence for each of M=0, 1, 2, ..., M-1). ). Further, each row of the base sequence 300-b may correspond to a frequency tone index l, where l=0 in the first row (e.g., the bottom row) and increments by 1 until l=M-1 in the last column (e.g., the top row). In this way, each frequency tone index l may correspond to a frequency tone of a resource allocation associated with the transmission of a payload. Accordingly, a number of base sequences 300-b may be considered (e.g., a number equal to M), and the number of base sequences 300-b may be visualized as a base sequence of dimension M×M (e.g., M cyclic shifts×M frequency tones). The matrix of .

[0117] As described herein, the base station 105 or the UE 115 or both may generate a set of orthogonal sequences. In some examples, the base station 105 or the UE 115 or both may generate a plurality of orthogonal sequences based on a product (such as a Kronecker product) of an orthogonal matrix 300-a and each of a plurality of base sequences 300-b. The Kronecker product of the orthogonal matrix 300-a and each of the plurality of base sequences 300-b may involve determining the Kronecker product of each row or column n of the orthogonal matrix 300-a and each cyclic shift index m of the base sequence 300-b, and repeating the operation for all permutations of n and m, where n=0, 1, ..., N-1 and m=0, 1, ..., M-1.

[0118] In this way, the number of orthogonal sequences in the set can be equal to the product of the dimension of the orthogonal matrix 300-a and the matrix representation of the base sequence 300-b. For example, the orthogonal matrix 300-a can be a matrix of size N×N, and the base sequence 300-b can be represented by a matrix of size M×M, and therefore, the Kronecker product between the two can result in a (N×M)×(N×M) matrix. In other words, the base station 105 or the UE 115 or both can generate a number of orthogonal sequences equal to N×M, and each orthogonal sequence can have a length of N×M. In this way, each orthogonal sequence can have a length equal to the number of resource elements included in the resource grid allocated to the UE 115 for transmission of the payload (e.g., OFDM symbol×the number of frequency-modulated resource elements).

[0119] In this way, the base station 105 or the UE 115 or both may generate an orthogonal sequence set based on the product of an orthogonal matrix having a size corresponding to the number of time periods and a cell-specific sequence of cyclic shifts having a length corresponding to the number of frequency tones, which may convey the payload across the resources allocated for the payload. The base station 105 or the UE 115 or both may repeat the Kronecker product for each unique pair (e.g., each unique (n, m) pair) of the row or column index n of the orthogonal matrix 300-a and each cyclic shift index m of the base sequence 300-b to generate N*M orthogonal sequences, each of which may convey the payload across each resource element in the resource grid defined by N OFDM symbols and M frequency tones. In some implementations, the base station 105 or the UE 115 or both may construct a codebook of a set of N*M orthogonal sequences based on the number of bits in the payload.

[0120] However, using Figure 3A and Figure 3B The sequences generated by the example techniques described in may be susceptible to high Doppler or large delay spread. For example, different columns of the orthogonal matrix 300-a may correspond to time domain phase slopes relative to each other column. Similarly, different entries of the base sequence 300-b may correspond to frequency domain phase slopes relative to each other slope. The phase slope properties of these sequences (in the time or frequency domain) and the sequences resulting from their multiplication may increase the likelihood of reception errors at a receiver that is experiencing certain RF propagation phenomena (e.g., high Doppler and / or large delay spread) because these time or frequency domain propagation phenomena may appear to the receiver as representing a sequence from a codebook that is different from the sequence used by the transmitter to convey the payload. Thus, in accordance with aspects of the present disclosure, the sequence selected to convey the payload (e.g., from a codebook) may be modified. Figure 3A and Figure 3B The orthogonal sequences generated by the process described in are interleaved (e.g., using a nonlinear interleaving function) to mitigate the effects of Doppler or delay spread by breaking the linear phase ramp properties of the sequences.

[0121] Figure 4 An example interleaving operation 400 is illustrated to support sequence interleaving for communicating a multi-bit payload in accordance with various aspects of the present disclosure. In some examples, a base station 105 or a UE 115 or both (which may be examples of corresponding devices as described herein) may perform an interleaving operation 400 to manage or improve sequence-based wireless communications when combating high Doppler spread, high delay spread, high Doppler shift, high delay shift, or a combination thereof. For example, a base station 105 or a UE 115 or both may generate a sequence (e.g., an orthogonal sequence) 405 (e.g., a=[a0, ..., a K-1], where a corresponds to the value of the bit and K is equal to the number of bits in the payload).

[0122] In some examples, the base station 105 or the UE 115 or both may generate a sequence 405a=[a0, ..., a K-1 ] to generate a virtual matrix 410 having a number of rows equal to the number of frequency tones used to convey the payload and a number of columns equal to the number of symbols used to convey the payload. In some examples, the base station 105 or the UE 115 or both may apply an interleaving function to the generated sequence 405a=[a0, ..., a K-1 ] elements or values ​​within a row of the virtual matrix, as illustrated by row interleaving 415. For example, base station 105 or UE 115 or both may permute the rows of the virtual matrix. In some examples, within each row of the virtual matrix, the elements (a0, ..., a K-1 ) is unchanged. Thus, the base station 105 or the UE 115 or both can interleave the subcarriers, and the same interleaver is applied to all symbol periods (e.g., OFDM symbols). In such examples, the length of the interleaving function is based on the number of time periods used to convey the payload (or otherwise based on the number of columns in the virtual matrix 410).

[0123] In some examples, the base station 105 or the UE 115 or both may apply an interleaving function to the generated sequence 405a=[a0, ..., a K-1 ] elements or values ​​within a column of the virtual matrix 405, as illustrated by column interleaving 420. For example, the base station 105 or the UE 115 or both may permute the columns of the virtual matrix. In some examples, within each column of the virtual matrix, the elements (a0, ..., a K-1 ) is unchanged. Thus, the base station 105 or the UE 115 or both can apply the same interleaver to all symbol periods (e.g., OFDM symbols) of each subcarrier. In such examples, the length of the interleaving function is based on the number of frequency tones used to convey the payload (or otherwise based on the number of rows in the virtual matrix 410).

[0124] In other examples, the base station 105 or the UE 115 or both may apply an interleaving function to the generated sequence 405a=[a0, ..., a K-1 ] the elements or values ​​in the rows of the virtual matrix and the generated sequence 405a=[a0,...,a K-1 ] values ​​within the columns of the virtual matrix, as illustrated by row and column interleaving 425. In some examples, within each column and each row of the virtual matrix, the elements (a0, ..., a K-1The interleaving function described with respect to the interleaving operation 400 is an example, and any other interleaving function may be used, such as a random interleaving function, an interleaving function defined by a formula, or an interleaving function defined by a table, as shown in FIG. Figure 3A as described.

[0125] The base station or UE 115 or both may thereby experience improvements to sequence-based wireless communications by supporting interleaving or permutation of sequences. In some examples, configuring the base station 105 or UE 115 or both to support sequence-based wireless communications may support improvements to sequence-based wireless communications, such as, for example, facilitating higher reliability and lower latency sequence-based wireless communications, among other benefits.

[0126] Figure 5 An example of a process flow 500 according to aspects of the present disclosure is illustrated. The process flow 500 may be implemented as described with reference to Figure 1 and 2 The process flow 500 may include aspects of the wireless communication systems 100 and 200 described herein. For example, the process flow 500 may reduce power consumption based on a configuration provided by the base station 105 and implemented by the UE 115, and may facilitate high reliability and low latency sequence-based wireless communication and other benefits. In the following description of the process flow 500, operations between the base station 105 and the UE 115 may be transmitted in an order different from the example order shown, or operations performed by the base station 105 and the UE 115 may be performed in a different order or at a different time. Some operations may also be omitted from the process flow 500, and other operations may be added to the process flow 500.

[0127] At 505, UE 115 (e.g., a transmitting device) may select a sequence for conveying a payload including a set of information bits. For example, UE 115 may select a sequence for conveying a payload including a set of information bits from a set of orthogonal sequences or non-orthogonal sequences. The length of the selected sequence may depend on the number of time periods used to convey the payload and the number of frequency tones used to convey the payload. In some examples, UE 115 may generate an orthogonal sequence set based on the product of an orthogonal matrix having a size corresponding to the number of time periods and a cell-specific sequence of cyclic shifts having a length corresponding to the number of frequency tones. The product may be a Kronecker product, and the orthogonal matrix may be a DFT matrix. Similarly, base station 105 may perform the same or similar operations when transmitting a payload to UE 115.

[0128] At 510, UE 115 may apply an interleaving function to the selected sequence. For example, UE 115 may apply an interleaving function to the selected sequence to generate an interleaved sequence. In some examples, UE 115 may identify the interleaving function based on a table that maps an element index of the selected sequence to an element index of the interleaved sequence. In some other examples, UE 115 may identify the interleaving function based on an equation that defines the interleaving function. In other examples, UE 115 may receive signaling indicating the interleaving function, or signaling configured to convey the interleaving of the payload, or both. The signaling may be RRC signaling, media access control-control element (MAC-CE) signaling, or DCI signaling, etc. For example, as Figure 3B As described, UE 115 may map the interleaved sequences to physical resources corresponding to the number of time periods used to convey the payload and the number of frequency tones used to convey the payload. Similarly, base station 105 may perform the same or similar operations when transmitting a payload to UE 115.

[0129] UE115 may generate a virtual matrix from the selected sequence, the virtual matrix having a number of rows equal to the number of frequency modulations used to convey the payload and a number of columns equal to the number of time periods used to convey the payload. In some examples, UE 115 may apply an interleaving function to the elements or values ​​of the selected sequence in the columns of the virtual matrix. The length of the interleaving function may be based on the number of frequency modulations used to convey the payload. In some other examples, UE 115 may apply an interleaving function to the elements or values ​​of the selected sequence in the rows of the virtual matrix. The length of the interleaving function may be based on the number of time periods used to convey the payload. In other examples, UE 115 may apply an interleaving function to the elements or values ​​of the selected sequence in the rows of the virtual matrix and the elements or values ​​of the selected sequence in the columns of the virtual matrix. The length of the interleaving function may depend on the product of the number of time periods used to convey the payload and the number of frequency modulations used to convey the payload. Similarly, base station 105 may perform the same or similar operations when transmitting a payload to UE 115. At 515, UE115 may transmit a payload to base station 105 using an interleaved sequence.

[0130] At 520, the base station 105 (e.g., a receiving device) may apply an interleaving function to deinterleave the interleaved sequence. For example, the base station 105 may use the interleaved sequence to receive a payload including a set of information bits, and apply the interleaving function to deinterleave the interleaved sequence to generate a selected sequence (e.g., a sequence used by the UE 115 to convey the payload). The length of the interleaved sequence may depend on the number of time periods used to convey the payload and the number of frequency tones used to convey the payload. In some examples, the base station 105 may identify the interleaving function based on a table that maps the element index of the selected sequence to the element index of the interleaved sequence. In some other examples, the base station 105 may identify the interleaving function based on an equation that defines the interleaving function. At 525, the base station 105 may decode the payload based on the selected sequence determined according to the deinterleaving process.

[0131] Figure 6 A block diagram 600 of a device 605 supporting sequence interleaving for communicating a multi-bit payload in accordance with aspects of the present disclosure is shown.

[0137] The transmitter 620 can transmit signals generated by other components of the device 605. In some examples, the transmitter 620 can be co-located with the receiver 610 in a transceiver module. For example, the transmitter 620 can be a reference Fig.10 Examples of aspects of the described transceiver 920. The transmitter 620 may utilize a single antenna or a collection of antennas.

[0138] Figure 7 A block diagram 700 of a device 705 supporting sequence interleaving for communicating a multi-bit payload according to aspects of the present disclosure is shown. The device 705 may be an example of aspects of the device 605 or the device 115 as described herein. The device 705 may include a receiver 710, a communication manager 715, and a transmitter 740. The device 705 may also include a processor. Each of these components may be in communication with each other (e.g., via one or more buses).

[0139] The receiver 710 may receive information such as packets, user data, or control information associated with various information channels (e.g., control channels, data channels, and information related to sequence interleaving for conveying multi-bit payloads, etc.). The information may be passed to other components of the device 705. The receiver 710 may be a reference Fig.10 Examples of aspects of the described transceiver 920. The receiver 710 may utilize a single antenna or a collection of antennas.

[0140] Communications manager 715 may be an example of aspects of communications manager 615 as described herein. Communications manager 715 may include sequence component 720, interleaving component 725, payload component 730, and decoding component 735. Communications manager 715 may be an example of aspects of communications manager 910 as described herein.

[0141] The sequence component 720 can select a sequence from the set of sequences for conveying a payload including a set of bits, wherein the length of the selected sequence is based on the number of time periods for conveying the payload and the number of frequency tones for conveying the payload. The interleaving component 725 can apply an interleaving function to the selected sequence to generate an interleaved sequence.

The communication manager 805 can be an example of aspects of the communication manager 615, the communication manager 715, or the communication manager 1010 described herein. The communication manager 805 can include a sequence component 810, an interleaving component 815, a payload component 820, a configuration component 825, a matrix component 830, and a decoding component 835. Each of these modules can communicate with each other directly or indirectly (e.g., via one or more buses).

[0145] The sequence component 810 may select a sequence from a sequence set for conveying a payload including a set of bits, wherein the length of the selected sequence is based on the number of time periods used to convey the payload and the number of frequency tones used to convey the payload. In some examples, the sequence component 810 may generate a sequence set based on the product of an orthogonal matrix having a size corresponding to the number of time periods and a cell-specific sequence of cyclic shifts having a length corresponding to the number of frequency tones, wherein the sequence set includes orthogonal sequences. In some cases, the product includes a Kronecker product. In some cases, the orthogonal matrix includes a DFT matrix. In some cases, the sequence set includes orthogonal sequences or non-orthogonal sequences.

[0146] Interleaving component 815 may apply an interleaving function to a selected sequence to generate an interleaved sequence. In some examples, interleaving component 815 may apply an interleaving function to deinterleave the interleaved sequence to generate the selected sequence. In some examples, interleaving component 815 may identify an interleaving function based on a table that maps an element index of the selected sequence to an element index of the interleaved sequence.
