[0004] Related technologies

[0005] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, broadcasts or other similar types of services. These wireless communication systems may employ multiple-access technologies capable of supporting communication with multiple users by sharing available wireless communication system resources with those users.

[0006] Although wireless communication systems have made tremendous technical progress over the years, challenges still exist.

[0026] Aspects of the present disclosure provide apparatus, methods, processing systems, and computer-readable media for processing data transmissions overlapping with energy harvesting (EH) opportunities.

[0027] A new generation of wireless devices can overcome the conventional limitations of onboard energy storage by harvesting energy from wireless signals (e.g., radio frequency (RF) signals) to perform wireless communications. Such energy harvesting devices may include, for example, user equipment (UE) and various other types of devices, such as radio frequency identification (RFID) devices (e.g., RFID tags). Energy harvesting devices can be considered a type of user equipment (UE) that provides a low-cost and low-power solution for many applications in wireless communication systems.

[0028] In some use cases, the main purpose of collecting energy is to be used in tasks such as data decoding, data reception, data encoding, and data transmission. The EH device may have a limited energy storage unit to store the collected energy, and the stored energy can be used to perform data decoding, encoding, filtering, processing, etc. In other cases, the purpose is not to fully charge the mobile phone battery, but to charge the battery of the device (such as a wearable smart watch or a UE with extremely low power or using an EH dedicated battery) in a way that enables the use of the collected energy to perform some tasks. Various tasks such as data decoding, operating certain filters, data encoding, sending or receiving data can be completed by the accumulation of energy collected over time. In some cases, the EH operating mode may occur when the battery of the UE (e.g., a phone) is at a critical low power level, and the energy collection mode can be used. In some cases, the EH module can be operated by the UE in an extremely low power mode, or when the UE decides to use such a low power saving mode. This can be based on a request for the EH operating mode requested from the UE to the NW.

[0029] In some cases, EH may refer to a variety of EH technologies / schemes to be implemented by an EH device. Examples of these EH technologies / schemes may include radio frequency (RF) EH, optical / laser EH, and solar EH. In some cases, EH in this disclosure refers to any wireless EH technology, such as RF and laser (using a laser beam), that can be provided from one device (e.g., a gNB) to an EH device (e.g., a UE). However, these ideas are applicable to other forms of wireless charging / transfer that can be supported from one device to another.

[0030] A network deployment device (node) that can operate in this manner may be referred to as a self-sustainable network. This is because nodes can interact in the network by sending collected energy. In some cases, semi-persistent scheduling (SPS) EH opportunities (time periods) may be assigned to EHs, which can help ensure that devices have sufficient opportunities to collect energy. However, a potential problem is that such SPS EH opportunities may overlap with SPS data opportunities. In the case where a power splitter is used for EH purposes, SPS data processing may be affected by energy collection. For example, the effective signal to interference plus noise ratio (SINR) of SPS data may be different (lower) when EH is being executed than when EH is not being executed.

[0031] However, aspects of the present disclosure provide processing techniques that can account for the overlap of SPS data with EH opportunities. For example, in some cases, when an SPS data opportunity overlaps an EH opportunity, a different (lower) modulation and coding scheme (MCS) can be used. By adjusting the MCS to account for the overlap between SPS data and EH opportunities, data can be decoded more reliably and overall performance can be improved.

[0032] Introduction to wireless communication networks

[0033] The techniques and methods described herein can be used in various wireless communication networks. Although various aspects may be described herein using terms commonly associated with 3G, 4G and / or 5G wireless technologies, various aspects of the present disclosure may also be applicable to other communication systems and standards not explicitly mentioned herein.

[0034] Figure 1 An example of a wireless communication network 100 is depicted in which various aspects described herein may be implemented.

[0035] In general, the wireless communication network 100 includes various network entities (alternatively, network elements or network nodes). A network entity is typically a communication device and / or a communication function performed by a communication device (e.g., user equipment (UE), base station (BS), component of a BS, server, etc.). For example, various functions of a network and various devices associated with and interacting with the network may be considered network entities. In addition, the wireless communication network 100 includes ground aspects, such as ground-based network entities (e.g., BS 102), and non-ground aspects, such as satellites 140 and aircraft 145, which may include airborne network entities (e.g., one or more BSs) capable of communicating with other network elements (e.g., ground BSs) and user equipment.

[0036] In the depicted example, the wireless communication network 100 includes a BS 102, a UE 104, and one or more core networks (such as an evolved packet core (EPC) 160 and a 5G core (5GC) network 190) that interoperate to provide communication services over various communication links (including wired and wireless links).

[0037] Figure 1 Various example UEs 104 are depicted, which may more generally include: a cellular phone, a smart phone, a Session Initiation Protocol (SIP) phone, a laptop, a personal digital assistant (PDA), a satellite radio, a global positioning system, a multimedia device, a video device, a digital audio player, a camera, a game console, a tablet computer, a smart device, a wearable device, a vehicle, an electric meter, a gas pump, a large or small kitchen appliance, a healthcare device, an implant, a sensor / actuator, a display, an Internet of Things (IoT) device, an Always-On (AON) device, an edge processing device, or other similar devices. UE 104 may also be more generally referred to as a mobile device, a wireless device, a wireless communication device, a station, a mobile station, a subscriber station, a mobile subscriber station, a mobile unit, a subscriber unit, a wireless unit, a remote unit, a remote device, an access terminal, a mobile terminal, a wireless terminal, a remote terminal, a handset, and others.

[0038] BS 102 communicates wirelessly with (e.g., sends signals to or receives signals from) UE 104 via communication link 120. Communication link 120 between BS 102 and UE 104 may include uplink (UL) (also referred to as a reverse link) transmissions from UE 104 to BS 102 and / or downlink (DL) (also referred to as a forward link) transmissions from BS 102 to UE 104. In various aspects, communication link 120 may use multiple-input multiple-output (MIMO) antenna technology, including spatial multiplexing, beamforming, and / or transmit diversity.

[0039] BS 102 may generally include: NodeB, enhanced NodeB (eNB), next generation enhanced NodeB (ng-eNB), next generation NodeB (gNB or gNodeB), access point, base transceiver station, radio base station, radio transceiver, transceiver function, transmission and reception point, and / or other. Each of BS 102 may provide communication coverage for a corresponding geographic coverage area 110, which may sometimes be referred to as a cell, and may overlap in some cases (e.g., a small cell 102' may have a coverage area 110' that overlaps with the coverage area 110 of a macro cell). For example, a BS may provide communication coverage for a macro cell (covering a relatively large geographic area), a pico cell (covering a relatively small geographic area, such as a stadium), a femto cell (relatively small geographic area (e.g., a home)), and / or other types of cells.

[0040] Although BS102 is depicted as a single communication device in various aspects, BS102 can be implemented in various configurations. For example, one or more components of the base station may be decomposed, including a central unit (CU), one or more distributed units (DU), one or more radio units (RU), a near real-time (near RT) RAN intelligent controller (RIC), or a non-real-time (non-RT) RIC, to name a few examples. In another example, various aspects of the base station may be virtualized. More generally, a base station (e.g., BS102) may include components located at a single physical location or components located at various physical locations. In an example in which the base station includes components located at various physical locations, each component may perform a function so that each component together implements a function similar to that of a base station located at a single physical location. In some aspects, a base station including components located at various physical locations may be referred to as a decomposed radio access network architecture (such as an open RAN (O-RAN) or virtualized RAN (VRAN) architecture). Figure 2 An example decomposed base station architecture is depicted and described.

[0041] Different BSs 102 within the wireless communication network 100 may also be configured to support different radio access technologies (such as 3G, 4G, and / or 5G). For example, a BS 102 configured for 4G LTE (collectively referred to as the Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN)) may interface with the EPC 160 via a first backhaul link 132 (e.g., an S1 interface). A BS 102 configured for 5G (e.g., 5G NR or Next Generation RAN (NG-RAN)) may interface with the 5GC 190 via a second backhaul link 184. The BSs 102 may communicate with each other directly or indirectly (e.g., via the EPC 160 or the 5GC 190) over a third backhaul link 134 (e.g., an X2 interface), which may be wired or wireless.

[0042] The wireless communication network 100 may subdivide the electromagnetic spectrum into various categories, frequency bands, channels, or other characteristics. In some aspects, the subdivision is provided based on wavelength and frequency, where frequency may also be referred to as a carrier, subcarrier, channel, tone, or subband. For example, 3GPP currently defines frequency range 1 (FR1) as including 410 MHz-7125 MHz, which is often (interchangeably) referred to as "below 6 GHz". Similarly, 3GPP currently defines frequency range 2 (FR2) as including 24,250 MHz-52,600 MHz, which is sometimes (interchangeably) referred to as "millimeter wave" ("mmW" or "mmWave"). A base station (e.g., a mmWave base station such as BS180) configured to communicate using mmWave / near mmWave radio bands may utilize beamforming (e.g., 182) with a UE (e.g., 104) to improve path loss and range.

[0043] The communication link 120 between the BS 102 and, for example, the UE 104 may be through one or more carriers, which may have different bandwidths (e.g., 5 MHz, 10 MHz, 15 MHz, 20 MHz, 100 MHz, 400 MHz, and / or other MHz) and may be aggregated in various aspects. The carriers may or may not be adjacent to each other. The allocation of carriers may be asymmetric with respect to DL and UL (e.g., more or fewer carriers may be allocated for DL ​​compared to UL).

[0044] Communications using higher frequency bands may have higher path loss and shorter range than communications at lower frequencies. Figure 1180) may utilize beamforming 182 with UE 104 to improve path loss and range. For example, BS 180 and UE 104 may each include multiple antennas, such as antenna elements, antenna panels, and / or antenna arrays, to facilitate beamforming. In some cases, BS 180 may send beamformed signals to UE 104 in one or more transmit directions 182'. UE 104 may receive beamformed signals from BS 180 in one or more receive directions 182". UE 104 may also send beamformed signals to BS 180 in one or more transmit directions 182". BS 180 may also receive beamformed signals from UE 104 in one or more receive directions 182'. BS 180 and UE 104 may then perform beam training to determine the best receive and transmit directions for each of BS 180 and UE 104. It is noteworthy that the transmit direction and receive direction of BS 180 may be the same or different. Similarly, the transmit direction and receive direction of UE 104 may be the same or different.

[0045] Wireless communication network 100 also includes Wi-Fi AP 150 that communicates with Wi-Fi station (STA) 152 via communication link 154 in, for example, the 2.4 GHz and / or 5 GHz unlicensed spectrum.

[0046] Certain UEs 104 may communicate with each other using a device-to-device (D2D) communication link 158. The D2D communication link 158 may use one or more sidelink channels, such as a physical sidelink broadcast channel (PSBCH), a physical sidelink discovery channel (PSDCH), a physical sidelink shared channel (PSSCH), a physical sidelink control channel (PSCCH), and / or a physical sidelink feedback channel (PSFCH).

[0047] The EPC 160 may include various functional components, including: a mobility management entity (MME) 162, other MMEs 164, a serving gateway 166, a multimedia broadcast multicast service (MBMS) gateway 168, a broadcast multicast service center (BM-SC) 170, and / or a packet data network (PDN) gateway 172, such as in the depicted example. The MME 162 may communicate with a home subscriber server (HSS) 174. The MME 162 is a control node that handles signaling between the UE 104 and the EPC 160. In general, the MME 162 provides bearer and connection management.

[0048] Generally, user Internet Protocol (IP) packets are delivered through the Serving Gateway 166, which itself is connected to the PDN Gateway 172. The PDN Gateway 172 provides UE IP address allocation and other functions. The PDN Gateway 172 and the BM-SC 170 are connected to the IP Services 176, which may include, for example, the Internet, an Intranet, an IP Multimedia Subsystem (IMS), a Packet Switched (PS) streaming media service, and / or other IP services.

[0049] The BM-SC 170 may provide functionality for MBMS user service provisioning and delivery. The BM-SC 170 may serve as an entry point for content provider MBMS delivery, may be used to authorize and initiate MBMS bearer services within a public land mobile network (PLMN), and / or may be used to schedule MBMS delivery. The MBMS Gateway 168 may be used to distribute MBMS services to BSs 102 belonging to a multicast broadcast single frequency network (MBSFN) area broadcasting a specific service, and / or may be responsible for session management (start / stop) and for collecting eMBMS related charging information.

[0050] 5GC 190 may include various functional components, including: access and mobility management function (AMF) 192, other AMFs 193, session management function (SMF) 194, and user plane function (UPF) 195. AMF 192 may communicate with unified data management (UDM) 196.

[0051] AMF 192 is a control node that handles signaling between UE 104 and 5GC 190. AMF 192 provides, for example, Quality of Service (QoS) flow and session management.

[0052] Internet Protocol (IP) packets are delivered through UPF 195, which is connected to IP Services 197 and provides UE IP address allocation and other functions for 5GC 190. IP Services 197 may include, for example, the Internet, Intranet, IMS, PS streaming services, and / or other IP services.

[0053] In various aspects, a network entity or network node may be implemented as a converged base station, a decomposed base station, a component of a base station, an integrated access and backhaul (IAB) node, a relay node, a sidelink node, to name a few examples.

[0054] Figure 2An example disaggregated base station 200 architecture is depicted. The disaggregated base station 200 architecture may include one or more central units (CUs) 210 that may communicate directly with a core network 220 via a backhaul link, or indirectly with the core network 220 through one or more disaggregated base station units, such as a near real-time (near-RT) RAN intelligent controller (RIC) 225 via an E2 link, or a non-real-time (non-RT) RIC 215 associated with a service management and orchestration (SMO) framework 205, or both. The CU 210 may communicate with one or more distributed units (DUs) 230 via respective midhaul links, such as an F1 interface. The DU 230 may communicate with one or more radio units (RUs) 240 via respective fronthaul links. The RU 240 may communicate with respective UEs 104 via one or more radio frequency (RF) access links. In some implementations, a UE 104 may be served simultaneously by multiple RUs 240.

[0055] Each of the units (e.g., CU 210, DU 230, RU 240, and near-RT RIC 225, non-RT RIC 215, and SMO framework 205) may include or be coupled to one or more interfaces configured to receive or send signals, data, or information (collectively, signals) via a wired or wireless transmission medium. Each of the units or an associated processor or controller that provides instructions to the communication interface of the unit may be configured to communicate with one or more of the other units via a transmission medium. For example, the units may include a wired interface configured to receive or send signals to one or more of the other units via a wired transmission medium. Additionally or alternatively, the unit may include a wireless interface that may include a receiver, a transmitter, or a transceiver (such as a radio frequency (RF) transceiver) configured to receive or send signals, or both, to one or more of the other units on a wireless transmission medium.

[0056] In some aspects, CU 210 may host one or more higher layer control functions. Such control functions may include radio resource control (RRC), packet data convergence protocol (PDCP), service data adaptation protocol (SDAP), etc. Each control function may be implemented using an interface configured to communicate signals with other control functions hosted by CU 210. CU 210 may be configured to handle user plane functions (e.g., central unit-user plane (CU-UP)), control plane functions (e.g., central unit-control plane (CU-CP)), or a combination thereof. In some specific implementations, CU 210 may be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP unit may communicate bidirectionally with the CU-CP unit via an interface (such as an E1 interface). As needed, CU 210 may be implemented to communicate with DU 230 for network control and signaling.

[0057] DU 230 may correspond to a logical unit that includes one or more base station functions for controlling the operation of one or more RUs 240. In some aspects, DU 230 may host one or more of a radio link control (RLC) layer, a medium access control (MAC) layer, and one or more high physical (PHY) layers (such as modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, etc.) at least in part according to a functional split such as those defined by the 3rd Generation Partnership Project (3GPP). In some aspects, DU 230 may also host one or more low PHY layers. Each layer (or module) may be implemented using an interface that is configured to communicate signals with other layers (and modules) hosted by DU 230 or with control functions hosted by CU 210.

[0058] The lower layer functionality may be implemented by one or more RUs 240. In some deployments, a RU 240 controlled by a DU 230 may correspond to a logical node that hosts RF processing functions or low PHY layer functions (such as performing Fast Fourier Transform (FFT), Inverse FFT (iFFT), digital beamforming, physical random access channel (PRACH) extraction and filtering, etc.), or both, based at least in part on a functional split (such as a lower layer functional split). In such an architecture, the RU 240 may be implemented to handle over-the-air (OTA) communications with one or more UEs 104. In some implementations, real-time and non-real-time aspects of control plane and user plane communications with the RU 240 may be controlled by the corresponding DU 230. In some scenarios, this configuration may enable the implementation of the DU 230 and the CU 210 in a cloud-based RAN architecture (such as a vRAN architecture).

[0059] The SMO framework 205 may be configured to support RAN deployment and provisioning of non-virtualized network elements and virtualized network elements. For non-virtualized network elements, the SMO framework 205 may be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which may be managed via an operation and maintenance interface (such as an O1 interface). For virtualized network elements, the SMO framework 205 may be configured to interact with a cloud computing platform (such as an open cloud (O-Cloud) 290) to perform network element lifecycle management (such as instantiating virtualized network elements) via a cloud computing platform interface (such as an O2 interface). Such virtualized network elements may include, but are not limited to, CU 210, DU 230, RU 240, and near-RT RIC 225. In some specific implementations, the SMO framework 205 may communicate with hardware aspects of the 4G RAN (such as an open eNB (O-eNB) 211) via the O1 interface. Additionally, in some specific implementations, the SMO framework 205 may communicate directly with one or more RUs 240 via the O1 interface. The SMO framework 205 may also include a non-RT RIC 215 configured to support the functionality of the SMO framework 205 .

[0060] The non-RT RIC 215 may be configured to include logic functions that enable non-real-time control and optimization of RAN elements and resources, artificial intelligence / machine learning (AI / ML) workflows including model training and updating, or policy-based guidance of applications / features in the near-RT RIC 225. The non-RT RIC 215 may be coupled to or in communication with the near-RT RIC 225 (such as via an A1 interface). The near-RT RIC 225 may be configured to include logic functions that enable near-real-time control and optimization of RAN elements and resources via data collection and actions through an interface (such as via an E2 interface) that connects one or more CUs 210, one or more DUs 230, or both, and the O-eNB with the near-RT RIC 225.

[0061] In some implementations, in order to generate an AI / ML model to be deployed in the near-RT RIC 225, the non-RT RIC 215 may receive parameters or external enrichment information from an external server. Such information may be utilized by the near-RT RIC 225 and may be received from a non-network data source or from a network function at the SMO framework 205 or the non-RT RIC 215. In some examples, the non-RT RIC 215 or the near-RT RIC 225 may be configured to tune RAN behavior or performance. For example, the non-RT RIC 215 may monitor long-term trends and patterns of performance and employ AI / ML models to perform corrective actions through the SMO framework 205 (such as via reconfiguration of O1) or via the creation of RAN management policies (such as A1 policies).

[0062] Figure 3 Aspects of an example BS 102 and UE 104 are depicted.

[0063] In general, BS 102 includes various processors (e.g., 320, 330, 338, and 340), antennas 334a-334t (collectively 334), transceivers 332a-332t (collectively 332) including modulators and demodulators, and other aspects that enable wireless transmission of data (e.g., data source 312) and wireless reception of data (e.g., data sink 339). For example, BS 102 can transmit and receive data between BS 102 and UE 104. BS 102 includes a controller / processor 340 that can be configured to implement various functions described herein related to wireless communication.

[0064] Generally speaking, the UE 104 includes various processors (e.g., 358, 364, 366, and 380), antennas 352a-352r (collectively 352), transceivers 354a-354r (collectively 354) including modulators and demodulators, and other aspects that enable wireless transmission of data (e.g., retrieved from a data source 362) and wireless reception of data (e.g., provided to a data sink 360). The UE 104 includes a controller / processor 380 that can be configured to implement various functions described herein related to wireless communications.

[0065] Regarding example downlink transmissions, BS 102 includes a transmit processor 320 that can receive data from a data source 312 and control information from a controller / processor 340. The control information can be for a physical broadcast channel (PBCH), a physical control format indicator channel (PCFICH), a physical HARQ indicator channel (PHICH), a physical downlink control channel (PDCCH), a group common PDCCH (GC PDCCH), and / or others. In some examples, the data can be for a physical downlink shared channel (PDSCH).

[0066] The transmit processor 320 may process (e.g., encode and symbol map) data and control information to obtain data symbols and control symbols, respectively. The transmit processor 320 may also generate reference symbols (such as for a primary synchronization signal (PSS), a secondary synchronization signal (SSS), a PBCH demodulation reference signal (DMRS), and a channel state information reference signal (CSI-RS)).

[0067] The transmit (TX) multiple-input multiple-output (MIMO) processor 330 may perform spatial processing (e.g., pre-decoding) on ​​data symbols, control symbols, and / or reference symbols, where applicable, and may provide an output symbol stream to a modulator (MOD) in a transceiver 332a-332t. Each modulator in the transceiver 332a-332t may process a corresponding output symbol stream to obtain an output sample stream. Each modulator may further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The downlink signals from the modulators in the transceivers 332a-332t may be transmitted via antennas 334a-334t, respectively.

[0068] To receive downlink transmissions, UE 104 includes antennas 352a-352r that can receive downlink signals from BS 102 and can provide received signals to demodulators (DEMODs) in transceivers 354a-354r, respectively. Each demodulator in transceivers 354a-354r can condition (e.g., filter, amplify, downconvert, and digitize) a corresponding received signal to obtain input samples. Each demodulator can further process the input samples to obtain received symbols.

[0069] A MIMO detector 356 may obtain received symbols from all demodulators in transceivers 354a-354r, perform MIMO detection on the received symbols if applicable, and provide detected symbols. A receive processor 358 may process (e.g., demodulate, deinterleave, and decode) the detected symbols, provide decoded data for UE 104 to a data sink 360, and provide decoded control information to a controller / processor 380.

[0070] With respect to example uplink transmissions, the UE 104 also includes a transmit processor 364 that may receive and process data from a data source 362 (e.g., for a PUSCH) and control information from a controller / processor 380 (e.g., for a physical uplink control channel (PUCCH)). The transmit processor 364 may also generate reference symbols for reference signals (e.g., for a sounding reference signal (SRS)). The symbols from the transmit processor 364 may be pre-decoded by a TX MIMO processor 366, if applicable, further processed by a modulator in the transceivers 354a-354r (e.g., for SC-FDM), and transmitted to the BS 102.

[0071] At BS 102, uplink signals from UE 104 may be received by antennas 334 a-334 t, processed by demodulators in transceivers 332 a-332 t, detected by MIMO detector 336 if applicable, and further processed by receive processor 338 to obtain decoded data and control information transmitted by UE 104. Receive processor 338 may provide decoded data to data sink 339 and decoded control information to controller / processor 340.

[0072] Memory 342 and memory 382 may store data and program codes for BS 102 and UE 104, respectively.

[0073] The scheduler 344 may schedule UEs for data transmission on the downlink and / or uplink.

[0074] In various aspects, BS 102 may be described as sending and receiving various types of data associated with the methods described herein. In these contexts, "sending" may refer to various mechanisms for outputting data, such as outputting data from a data source 312, a scheduler 344, a memory 342, a transmit processor 320, a controller / processor 340, a TX MIMO processor 330, a transceiver 332a-332t, an antenna 334a-334t, and / or other aspects described herein. Similarly, "receiving" may refer to various mechanisms for obtaining data, such as obtaining data from an antenna 334a-334t, a transceiver 332a-332t, a RX MIMO detector 336, a controller / processor 340, a receive processor 338, a scheduler 344, a memory 342, and / or other aspects described herein.

[0075] In various aspects, the UE 104 may also be described as sending and receiving various types of data associated with the methods described herein. In these contexts, "sending" may refer to various mechanisms for outputting data, such as outputting data from a data source 362, a memory 382, ​​a transmit processor 364, a controller / processor 380, a TX MIMO processor 366, a transceiver 354a-354t, an antenna 352a-352t, and / or other aspects described herein. Similarly, "receiving" may refer to various mechanisms for obtaining data, such as obtaining data from an antenna 352a-352t, a transceiver 354a-354t, a RX MIMO detector 356, a controller / processor 380, a receive processor 358, a memory 382, ​​and / or other aspects described herein.

[0076] In some aspects, the processor may be configured to perform various operations (such as those associated with the methods described herein) and send (output) data to or receive (obtain) data from another interface configured to send or receive data, respectively.

[0077] Figure 4A , Figure 4B , Figure 4C and Figure 4D Describes a method for use in a wireless communication network such as Figure 1 Various aspects of the data structure of the wireless communication network 100).

[0078] Specifically, Figure 4A is a diagram 400 illustrating an example of a first subframe within a 5G (e.g., 5G NR) frame structure, Figure 4B is a diagram 430 illustrating an example of a DL channel within a 5G subframe, Figure 4C is a diagram 450 illustrating an example of a second subframe within a 5G frame structure, and Figure 4D FIG480 is a diagram illustrating an example of UL channels within a 5G subframe.

[0079] Wireless communication systems may utilize orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) on both the uplink and downlink. Such systems may also support half-duplex operation using time division duplex (TDD). OFDM and single carrier frequency division multiplexing (SC-FDM) can be used to maximize the system bandwidth (e.g., Figure 4B and Figure 4D The modulation symbols may be transmitted in the frequency domain using OFDM and / or in the time domain using SC-FDM.

[0080] The wireless communication frame structure may be frequency division duplex (FDD), where for a particular set of subcarriers, subframes within the set of subcarriers are dedicated to either DL or UL. The wireless communication frame structure may also be time division duplex (TDD), where for a particular set of subcarriers, subframes within the set of subcarriers are dedicated to both DL and UL.

[0081] exist Figure 4A and Figure 4C In the wireless communication frame structure, TDD is used, where D is DL, U is UL, and X is used flexibly between DL / UL. The UE can be configured with a time slot format (dynamically configured by DL control information (DCI) or semi-statically / statically configured by radio resource control (RRC) signaling) through the received time slot format indicator (SFI). In the depicted example, the 10ms frame is divided into 10 equally sized 1ms subframes. Each subframe may include one or more time slots. In some examples, each time slot may include 7 or 14 symbols, depending on the time slot format. The subframe may also include micro-time slots, which typically have fewer symbols than the entire time slot. Other wireless communication technologies may have different frame structures and / or different channels.

[0082] In certain aspects, the number of time slots within a subframe is based on the time slot configuration and the parameter set. For example, for time slot configuration 0, different parameter sets (μ) 0 to 5 allow for 1, 2, 4, 8, 16, and 32 time slots per subframe, respectively. For time slot configuration 1, different parameter sets 0 to 2 allow for 2, 4, and 8 time slots per subframe, respectively. Thus, for time slot configuration 0 and parameter set μ, there are 14 symbols / time slot and 2μ time slots / subframe. The subcarrier spacing and symbol length / duration are a function of the parameter set. The subcarrier spacing may be equal to 2 μ × 15kHz, where μ is parameter set 0 to 5. Thus, parameter set μ=0 has a subcarrier spacing of 15kHz, and parameter set μ=5 has a subcarrier spacing of 480kHz. The symbol length / duration is inversely related to the subcarrier spacing. Figure 4A , Figure 4B , Figure 4C and Figure 4D An example is provided for slot configuration 0 with 14 symbols per slot and parameter set μ=2 with 4 slots per subframe. The slot duration is 0.25 ms, the subcarrier spacing is 60 kHz, and the symbol duration is approximately 16.67 μs.

[0083] like Figure 4A , Figure 4B , Figure 4C and Figure 4DAs depicted in , a resource grid can be used to represent a frame structure. Each time slot includes a resource block (RB) (also called a physical RB (PRB)) extending, for example, 12 consecutive subcarriers. The resource grid is divided into a plurality of resource elements (REs). The number of bits carried by each RE depends on the modulation scheme.

[0084] like Figure 4A As illustrated, some REs carry Figure 1 and Figure 3 The RS may include a demodulation RS (DMRS) and / or a channel state information reference signal (CSI-RS) for channel estimation at the UE. The RS may also include a beam measurement RS (BRS), a beam refinement RS (BRRS), and / or a phase tracking RS (PT-RS).

[0085] Figure 4B Examples of various DL channels within a subframe of a frame are illustrated.The Physical Downlink Control Channel (PDCCH) carries DCI within one or more Control Channel Elements (CCEs), each CCE comprising, for example, nine RE Groups (REGs), each REG comprising, for example, four consecutive REs in an OFDM symbol.

[0086] The primary synchronization signal (PSS) may be in symbol 2 of a particular subframe of a frame. The PSS is transmitted by a UE (e.g., Figure 1 and Figure 3 104) is used to determine subframe / symbol timing and physical layer identity.

[0087] A Secondary Synchronization Signal (SSS) may be within symbol 4 of a particular subframe of a frame. The SSS is used by the UE to determine the physical layer cell identity group number and radio frame timing.

[0088] Based on the physical layer identity and the physical layer cell identity group number, the UE can determine the physical cell identifier (PCI). Based on the PCI, the UE can determine the location of the aforementioned DMRS. The physical broadcast channel (PBCH) carrying the master information block (MIB) can be logically grouped with the PSS and SSS to form a synchronization signal (SS) / PBCH block. The MIB provides the system frame number (SFN) and the number of RBs in the system bandwidth. The physical downlink shared channel (PDSCH) carries user data, broadcast system information (such as system information blocks (SIBs)) that is not sent via the PBCH, and / or paging messages.

[0089] like Figure 4CAs illustrated, some REs carry DMRS for channel estimation at the base station (indicated as R for a particular configuration, but other DMRS configurations are also possible). The UE may send DMRS for PUCCH and DMRS for PUSCH. The PUSCH DMRS may be sent, for example, in the first one or two symbols of the PUSCH. The PUCCH DMRS may be sent in different configurations depending on whether a short PUCCH or a long PUCCH is sent and depending on the specific PUCCH format used. UE 104 may send a sounding reference signal (SRS). The SRS may be sent, for example, in the last symbol of a subframe. The SRS may have a comb structure, and the UE may send the SRS on one of the teeth of the comb. The SRS may be used by the base station for channel quality estimation to achieve frequency-dependent scheduling of the UL.

[0090] Figure 4D Examples of various UL channels within a subframe of a frame are illustrated. The PUCCH may be located at a position as indicated in one configuration. The PUCCH carries uplink control information (UCI), such as scheduling requests, channel quality indicator (CQI), precoding matrix indicator (PMI), rank indicator (RI), and HARQ ACK / NACK feedback. The PUSCH carries data and may additionally be used to carry a buffer status report (BSR), a power headroom report (PHR), and / or UCI.

[0091] Overview of Energy Harvesting

[0092] UEs capable of energy harvesting (EH) are part of a rapidly evolving technology impacting many industries due to their economic potential for inventory / asset management within warehouses, the Internet of Things (IoT), sustainable sensor networks in factories and / or agriculture, and smart homes, to name just a few example applications.

[0093] Some types of UEs can operate without a battery. Typically, UEs that operate without a battery are referred to as passive devices. Examples of passive devices include passive RFID devices, which operate by harvesting energy from received radio frequency signals (e.g., "over the air") to power receive and transmit circuits within the device. This harvested energy allows the passive device to transmit information, sometimes referred to as backscatter modulated information, without the need for a local power source within the device.

[0094] In other cases, such as Figure 5 As illustrated, the UE may be semi-passive and include onboard energy storage to supplement its ability to harvest energy from received signals (however, at a higher cost).

[0095] In some aspects, in addition to harvesting power from RF sources, energy harvesting devices can also accumulate energy from other direct energy sources (such as solar energy) to supplement their power needs. In some cases, semi-passive energy harvesting devices can include power-consuming RF components such as analog-to-digital converters (ADCs), mixers, and oscillators.

[0096] Energy harvesting devices are a type of user equipment that provides low-cost and low-power solutions for many applications in wireless communication systems. Such devices can be very power efficient, sometimes requiring less than 0.1 mW of power to operate. In addition, their relatively simple architecture and, in some cases, the lack of a battery means that such devices can be small, light, and easy to install or integrate into many types of environments or host devices. In general, EH-capable devices provide a practical and necessary solution for many networking applications that require low-cost, small footprint, durable, maintenance-free, and long-life communication devices. For example, EH-capable devices can be configured as long-durability industrial sensors, which alleviates the problem of replacing batteries in and around hazardous machinery.

[0097] Figure 5 An example system 500 is shown with a UE 550 configured to harvest energy from RF transmissions 525 from a network entity 510 (e.g., a gNB). In this mode of operation, the network entity 510 may also be referred to as an interrogator or scanner.

[0098] The network entity 510 includes an antenna 520 and an electronic unit 530. The antenna 520 radiates a signal transmitted by the reader 510 and receives a signal 5350 from a UE (such as UE 550) and / or other devices. The electronic unit 530 may include a transmitter and a receiver. The same pair of transmitter and receiver (or another pair of transmitter and receiver) may support two-way communication with a wireless network, a wireless device, etc. The electronic unit 530 may include a processing circuit (e.g., a processor) to perform processing on data transmitted and received by the network entity 510.

[0099] As shown, UE 550 includes an antenna 560 and a data storage element 570. Antenna 560 radiates signals transmitted by UE 550 and receives signals from network entity 510 and / or other devices. Data storage element 570 stores information for UE 550 in, for example, an electrically erasable programmable read-only memory (EEPROM) or another type of memory. UE 550 may also include an electronic unit that may process received signals and generate signals to be transmitted.

[0100] In some aspects, UE 550 may be a passive device without a battery. In this case, induction may be used to power UE 550. For example, in some cases, a magnetic field from a signal sent by network entity 510 may induce a current in UE 550, which may then operate based on the induced current. UE 550 may radiate its signal in response to receiving a signal from network entity 510 or some other device. In certain other aspects, UE 550 may optionally include an energy storage device 590, such as a battery, a capacitor, etc., for storing energy harvested using energy harvesting circuit 555, as described below.

[0101] Wireless technologies are increasingly useful in industrial applications such as ultra-reliable low-latency communications (URLLC) and machine-type communications (MTC). In such and other areas, it is desirable to support devices (e.g., passive RFID tags) that can harvest energy (such as RF signals, thermal energy, solar energy, etc.) from wireless energy sources (e.g., instead of or in combination with batteries or other energy storage devices (such as capacitors)).

[0102] There are various types of energy harvesting architectures, including separate receiver architectures, time-switched architectures, and power-split architectures. With separate receiver architectures, one receiver can be used to receive information (data processing) while a separate receiver is used for energy harvesting.

[0103] For a time-switched architecture, a node switches between an information receiver and an RF energy harvester. In this case, the energy harvested from source i at receiver j can be calculated as follows:

[0104] E j =ηP i |g i-j | 2 αT,

[0105] where 0≤α≤1 is the fraction of time allocated for energy harvesting. Let κ and W denote the noise spectral density and channel bandwidth, the data rate can be given as:

[0106]

[0107] like Figure 6 As illustrated, in a power split architecture, the received RF signal can be split into two streams for the information receiver and the RF energy harvester with different power levels. In this case, the energy harvested from source i at receiver j can be calculated as follows:

[0108] E j =ηρP i |g i-j | 2 T,

[0109] where 0≤ρ≤1 is the fraction of power allocated for energy harvesting. In this case, the data rate is given by:

[0110]

[0111] Example SPS PDSCH Configuration

[0112] Semi-persistent scheduling (SPS) resource allocation (sometimes referred to as configured downlink assignment) refers to a scheduling technique in which the user equipment (UE) is pre-configured with periodicity and offset by the network / base station (e.g., eNB, gNB, etc.).

[0113] like Figure 7 As illustrated, once preconfigured, if the UE is to receive an allocation of downlink resources, the allocation of SPS opportunities will be repeated according to the preconfigured periodicity p, resulting in periodic SPS opportunities. For SPS, the base station can use radio resource control (RRC) signaling to define the periodicity of the configured downlink assignments.

[0114] As used herein, the term opportunity generally refers to the time at which resources are allocated for a transmission that may or may not eventually occur. For example, a downlink transmission may or may not occur in an SPS opportunity. As shown, the UE may monitor the SPS opportunity at a certain time (K0) after the SPS configuration is activated via downlink control information (DCI). Parameter K1 specifies the PUCCH grant time in the time slot to transmit confirmation (HARQ-ACK) feedback after receiving the PDSCH in the SPS opportunity.

[0115] For SPS configuration, radio resource control (RRC) signaling usually configures SPS periodicity and HARQ-ACK feedback resources. Figure 8 As illustrated, SPS activation (and / or) reactivation may be triggered via DCI. Similarly, SPS release may also be triggered via DCI. A network entity (e.g., gNB) may use SPS activation DCI to activate a specific configured SPS. In the activation DCI, the gNB may indicate transmit (Tx) parameters such as modulation and coding scheme (MCS), RB allocation, and antenna ports for SPS transmission. The gNB may use SPS reactivation DCI to change Tx parameters (e.g., change one or more of MCS, RB allocation, or antenna ports for SPS).

[0116] Example Processing Techniques for Data Transmission Overlapping with Energy Harvesting (EH) Opportunities

[0117] As mentioned above, one potential problem with periodic transmissions (such as SPS or configured grant data) and EH schemes is that periodic EH opportunities may overlap with periodic data opportunities. For example, in the case where a power splitter is used for EH purposes (e.g., Figure 6 As shown), SPS data processing may be affected by energy harvesting. For example, the effective signal to interference plus noise ratio (SINR) of SPS data may be different (lower) when EH is being performed than when EH is not being performed. The present disclosure refers to the SPS data (PDSCH) opportunity as an example of a type of periodic transmission opportunity, and the techniques described herein may be applied to process any type of periodic transmission opportunity that overlaps with a periodically (e.g., SPS / configured grant) or dynamically / periodically allocated EH opportunity, including sidelink periodic transmissions between UEs or other types.

[0118] This may occur, for example, when data SPS is used to allow certain services such as Voice over Internet Protocol (VoIP) and periodic transmissions. With a single activation DCI, a train (or series) of PDSCH (or PUSCH) transmissions may be triggered and used to serve the UE. Aspects of the present disclosure provide techniques that may help account for situations where there is interaction (e.g., overlap) between EH opportunities and data SPS opportunities.

[0119] As will be described in more detail below, in some cases an offset / increment for the data MCS may be used. In other words, since an EH UE will use a power splitter, the effective SINR when EH is on may be different from (and lower than) the effective SINR when EH is off. Therefore, to account for this, a network entity (e.g., gNB) may use a different MCS for data transmissions that overlap with EH opportunities. An indication of the different MCS may be signaled to the UE.

[0120] For reference Fig. 9 The techniques proposed herein may be understood by referring to call flow diagram 900, which illustrates how a UE 904 may handle data transmission from a network entity 902 (e.g., a gNB or node of a decomposed base station) occurring in an SPS opportunity that overlaps with an EH opportunity.

[0121] As shown, the network entity may signal the SPS configuration to the UE. As described above, the SPS configuration may indicate a periodicity p for periodic SPS opportunities. Once SPS is activated (eg, via DCI), the UE may monitor SPS opportunities for data (PDSCH) transmission.

[0122] As shown, if the UE detects that an SPS PDSCH opportunity overlaps with a time period associated with EH, the UE may process the SPS PDSCH opportunity in a manner determined based on the overlap. For example, the UE may process an SPS PDSCH opportunity that overlaps in time with a first MCS that is lower than a second MCS used to process SPS PDSCH transmissions that do not overlap with EH operations.

[0123] The techniques described herein may consider various overlapping situations. Such situations may include, for example, a first situation where data SPS and EH SPS overlap, a second situation where data SPS and EH dynamic grant (DG) overlap, and a third situation where data SPS and EH discontinuous reception (DRX) overlap.

[0124] In some cases, a first set of configuration parameters may be utilized to process SPS PDSCH opportunities that are different from a second set of configuration parameters used to process SPS PDSCH opportunities that do not overlap with a time period associated with an EH. In some cases, the set of configuration parameters includes a modulation and coding scheme (MCS), a transmit port, a transmit rank, a power offset of a data channel or a demodulation reference signal (DMRS), a time domain resource allocation (TDRA), a frequency domain resource allocation (FDRA), a DMRS configuration, or at least one of any other parameters that may be provided in L1 / L2 / L3 signaling and may be adjusted due to overlap.

[0125] Fig.10 An example of a first case where the data SPS overlaps the EH SPS is illustrated. As shown, in this case, the MCS used for the DL when the EH is turned on can be lower than when there is no overlap between the data SPS and the EH SPS. In some cases, the amount of overlap may result in the need to transmit more MCS configuration information. For example, the configuration may indicate that a lower MCS is to be used when there is a certain amount of overlap (e.g., based on the number of symbols #sym that overlap).

[0126] In an SPS RRC configuration, the network entity may indicate an MCS increment (or offset). Alternatively, the network entity may indicate the MCS to be used in overlapping situations via RRC or medium access control (MAC) control element (CE) signaling. In some cases of partial overlap, the UE may discard the EH signal. In other words, in this case, the UE may not use the EH signal and may not operate the EH circuit, because this may mean enabling the power splitter, which may take some amount of time.

[0127] In some cases, when a partial or full allocation occurs, the gNB may require (or command) the UE to use two or more different power split factors. For example, the gNB may indicate the MCS to be used based on a threshold amount of OFDM symbol overlap. Different overlap scenarios may be associated by two or more MCS values, in addition to the value when there is no overlap with the EH SPS at all.

[0128] Fig.11 An example of the second case where the data SPS overlaps with an EH scheduled via a dynamic grant (DG) is illustrated. As shown, in this case, the EH DCI may schedule (indicate) one or more EH resources / allocations. The gNB may also indicate a new data MCS to use when the SPS opportunity overlaps with the data. To this end, an offset from the original data MCS may be signaled.

[0129] In general, the MCS may be a function of how much overlap there is between the data and the EH signal. In some cases, EH DG reception may be assumed to be an indication of canceling the data SPS opportunity (although this may be a function of how much symbol overlap there is between the two resources). In some cases, there may be a timeline defined for when a new MCS is valid after receiving the EH DCI. If this timeline is not met in time for a subsequent data SPS, the UE may discard the command and assume the old MCS.

[0130] Fig.12 An example of a third case where data SPS overlaps with EH DRX is illustrated. Various options exist for this scenario. For example, according to the first option, the gNB may indicate in the SPS activation or reactivation DCI a first MCS to be used if the EH circuit is open (MCS value 1) and a second MCS to be used if the EH circuit is closed (MCS value 2). In some cases, the MCS and offset may be configured.

[0131] According to the second option, based on the DRX design used by the UE, the gNB may adjust the data MCS accordingly without explicit signaling in the DCI. In some cases, the gNB may indicate (e.g., via RRC / MAC-CE) the MCS value / increment / offset to be used when the EH circuit is closed or open.

[0132] According to certain aspects, when the EH circuit is closed, the UE may cancel all SPS opportunities and / or any data. In other words, the UE may not be expected to monitor data for one or more SPS configurations or SPS plus DG. According to the first option, the gNB may not send any data to the UE. According to the second option, the gNB may still send this as data or as a dedicated / beamformed energy signal. In either case, the UE can harvest energy from the transmission.

[0133] Example Operation of User Equipment

[0134] Fig.13 It is shown that a UE (such as Figure 1 and Figure 3 An example of a method 1300 for performing wireless communications with a UE 104).

[0135] Method 1300 begins at step 1305, which detects that a periodic transmission (eg, SPS PDSCH) opportunity overlaps with a time period associated with an EH. In some cases, the operation of this step refers to or can be performed by reference to Fig.15 The described circuits for detection and / or codes for detection are implemented.

[0136] Then, method 1300 proceeds to step 1310, which processes the periodic transmission opportunity in a manner based on the overlap determination. In some cases, the operation of this step refers to or can be referred to as Fig.15 The described circuits for processing and / or codes for processing are performed.

[0137] In some aspects, the time period associated with EH comprises an SPS EH opportunity.

[0138] In some aspects, processing the SPS PDSCH opportunities in a manner based on overlap determination includes processing the SPS PDSCH opportunities with a first MCS that is lower than a second MCS used to process SPS PDSCH opportunities that do not overlap with a time period associated with an EH.

[0139] In some aspects, the method 1300 further includes determining the first MCS based on an absolute MCS value or an offset MCS value relative to the second MCS. In some cases, the operation of this step refers to or can be performed by reference to Fig.15 The described circuits for determining and / or codes for determining are performed.

[0140] In some aspects, the absolute MCS value or the offset MCS value is dynamically signaled or configured via RRC signaling.

[0141] In some aspects, the UE discards the EH signal when processing an SPS PDSCH opportunity.

[0142] In some aspects, the UE processes the EH signal using a first power split factor for an EH time period overlapping with an SPS PDSCH opportunity and using a second power split factor for an EH time period not overlapping with an SPS PDSCH opportunity.

[0143] In some aspects, the time period associated with the EH comprises an EH time period scheduled via the DCI.

[0144] In some aspects, processing the SPS PDSCH opportunity in a manner based on overlap determination includes processing the SPS PDSCH with an MCS indicated in the DCI.

[0145] In some aspects, the MCS indicated in the DCI is used to process the SPS PDSCH opportunity only if there is sufficient time between the DCI and the SPS PDSCH opportunity.

[0146] In some aspects, the SPS PDSCH opportunity is only cancelled if the overlap is greater than a threshold amount.

[0147] In some aspects, handling the SPS PDSCH opportunity in a manner based on the overlap determination includes canceling the SPS PDSCH opportunity.

[0148] In some aspects, the time period associated with the EH comprises a time period when EH circuitry of the UE is active.

[0149] In some aspects, processing the SPS PDSCH opportunities in a manner based on overlap determination includes processing the SPS PDSCH at a first MCS when the EH circuit is active that is lower than a second MCS used to process the SPS PDSCH opportunities when the EH circuit is inactive.

[0150] In some aspects, the first MCS and the second MCS are indicated via a DCI that activates or reactivates the SPS.

[0151] In some aspects, the first MCS and the second MCS are indicated via RRC or MAC-CE signaling.

[0152] In some aspects, handling the SPS PDSCH opportunity in a manner based on the overlap determination includes canceling the SPS PDSCH opportunity.

[0153] In one aspect, method 1300 or any aspect related thereto may be performed by an apparatus such as Fig.15 The method 1300 is performed by a communication device 1500, which includes various components that are operable, configured, or adapted to perform the method 1300. The communication device 1500 is described in more detail below.

[0154] It should be noted that Fig.13 This is merely one example of a method, and other methods including fewer, additional, or alternative steps may also be consistent with the present disclosure.

[0155] Example Operations of Network Entities

[0156] Fig.14 shows that network entities such as Figure 1 and Figure 3BS102 or as relative to Figure 2 An example of a method 1400 of performing wireless communications with a decomposed base station is discussed.

[0157] Method 1400 begins at step 1405, which detects that a periodic transmission (eg, SPS PDSCH) opportunity for a UE overlaps with a time period associated with an EH. In some cases, the operation of this step refers to or may be performed by reference to Fig.16 The described circuits for detection and / or codes for detection are implemented.

[0158] Then, method 1400 proceeds to step 1410, which processes the periodic transmission opportunity in a manner based on the overlap determination. In some cases, the operation of this step refers to or can be referred to as Fig.16 The described circuits for processing and / or codes for processing are performed.

[0159] In some aspects, the time period associated with EH comprises an SPS EH opportunity.

[0160] In some aspects, processing SPS PDSCH opportunities in an overlap-determined manner includes sending PDSCH in SPS PDSCH opportunities using a first MCS that is lower than a second MCS used to send PDSCH in SPS PDSCH opportunities that do not overlap with a time period associated with an EH.

[0161] In some aspects, the method 1400 also includes signaling to the UE an indication of the first MCS as an absolute MCS value or an offset MCS value relative to the second MCS.
