Description
[0001] CROSS-REFERENCE TO RELATED APPLICATIONS
[0002] This application claims the benefit of and priority to Greek Patent Application No. 20190100576, filed on December 24, 2019, which is assigned to the assignee of the present application and is hereby expressly incorporated herein by reference.
[0003] background
[0004] I. Public Domain
[0005] Aspects of the present disclosure relate to wireless communications and, more particularly, to techniques for user equipment to adapt operating bandwidth with reduced (or even zero) latency.
[0006] II. Description of Related Art
[0007] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, broadcast, etc. These wireless communication systems may employ multiple-access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple-access systems include Third Generation Partnership Project (3GPP) Long Term Evolution (LTE) systems, LTE-Advanced (LTE-A) systems, Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Access (FDMA) systems, Orthogonal Frequency Division Multiple Access (OFDMA) systems, Single Carrier Frequency Division Multiple Access (SC-FDMA) systems, and Time Division Synchronous Code Division Multiple Access (TD-SCDMA) systems, to name just a few.
[0008] In some examples, a wireless multiple access communication system may include several base stations (BS), each of which is capable of supporting communication of multiple communication devices (also referred to as user equipment (UE)) simultaneously. In an LTE or LTE-A network, a set of one or more base stations may define an evolved B node (eNB). In other examples (e.g., in a next generation, new radio (NR), or 5G network), a wireless multiple access communication system may include several distributed units (DUs) (e.g., edge units (EUs), edge nodes (ENs), radio heads (RHs), smart radio heads (SRHs), transmission reception points (TRPs), etc.) in communication with several central units (CUs) (e.g., central nodes (CNs), access node controllers (ANCs), etc.), wherein a set of one or more DUs in communication with a CU may define an access node (e.g., which may be referred to as a BS, a next generation B node (gNB or g B node), a TRP, etc.). A BS or DU may communicate with a set of UEs on a downlink channel (e.g., for transmission from a BS or DU to a UE) and an uplink channel (e.g., for transmission from a UE to a BS or DU).
[0009] These multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different wireless devices to communicate at a city, country, region, and even global level. New radio (e.g., 5G NR) is an example of an emerging telecommunication standard. NR is an enhancement set of the LTE mobile standard promulgated by 3GPP. NR is designed to better support mobile broadband Internet access by improving spectrum efficiency, reducing costs, improving services, utilizing new spectrum, and better integrating with other open standards using OFDMA with cyclic prefix (CP) on downlink (DL) and uplink (UL). To this end, NR supports beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation.
[0010] However, as the demand for mobile broadband access continues to grow, there is a need for further improvements to NR and LTE technologies. Preferably, these improvements should be applicable to other multiple access technologies and the telecommunication standards that employ these technologies.

[0041] Detailed Description
[0042] In many communication systems, when a UE adapts or changes the operating bandwidth (BW), a switching delay is usually imposed. However, in some cases, this switching delay can lead to lower spectral efficiency. For example, for a full-duplex (FD) communication system, the network may have to change the BW (including uplink (UL) / downlink (DL) allocation) from one time slot to another (or even within a time slot) without incurring such a switching delay.
[0043] To address this issue, aspects of the present disclosure provide apparatus, methods, processing systems, and computer-readable media that enable a UE operating with FD capability to adapt its operating BW with reduced (or zero) waiting time, compared to conventional techniques in which there is a switching delay caused by the UE adapting the operating BW. As described in more detail below, in certain aspects, one or more resource BWs within an active BW, such as an active bandwidth part (BWP), may be configured for the UE. Each resource BW within an active BWP may have a different time and / or frequency resource configuration. A resource BW may be viewed as a sub-BWP configuration, which may have contiguous or non-contiguous frequency resources within an active BWP. By defining multiple resource BWs in an active BWP in this manner, various aspects may enable the UE to switch to different resource BWs without incurring (or at least incurring reduced) switching delays.
[0044] The following description provides example techniques for adapting the operation of BW, but does not limit the scope, applicability or examples set forth in the claims. Changes may be made to the functions and arrangements of the elements discussed without departing from the scope of the present disclosure. Various examples may appropriately omit, replace, or add various procedures or components. For example, the described method may be performed in an order different from the order described, and various steps may be added, omitted, or combined. Moreover, the features described with reference to some examples may be combined in some other examples. For example, any number of aspects set forth herein may be used to implement a device or practice method. In addition, the scope of the present disclosure is intended to cover such devices or methods practiced using other structures, functionality, or structures and functionality as a supplement to the various aspects of the present disclosure set forth herein or in addition. It should be understood that any aspect of the present disclosure disclosed herein may be implemented by one or more elements of the claims. The wording "exemplary" is used herein to mean "used as an example, instance, or explanation". Any aspect described as "exemplary" herein is not necessarily to be interpreted as being superior to or superior to other aspects.
[0045] The techniques described herein may be used for various wireless communication technologies, such as 3GPP Long Term Evolution (LTE), Advanced LTE (LTE-A), Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single Carrier Frequency Division Multiple Access (SC-FDMA), Time Division Synchronous Code Division Multiple Access (TD-SCDMA), and other networks. The terms "network" and "system" are often used interchangeably.
[0046] A CDMA network may implement radio technologies such as Universal Terrestrial Radio Access (UTRA), cdma2000, etc. UTRA includes Wideband CDMA (WCDMA) and other variants of CDMA. cdma2000 covers IS-2000, IS-95, and IS-856 standards. A TDMA network may implement radio technologies such as Global System for Mobile Communications (GSM). An OFDMA network may implement radio technologies such as NR (e.g., 5G RA), Evolved UTRA (E-UTRA), Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE802.16 (WiMAX), IEEE 802.20, Flash-OFDMA, etc. UTRA and E-UTRA are part of Universal Mobile Telecommunications System (UMTS). LTE and LTE-A are versions of UMTS that use E-UTRA. UTRA, E-UTRA, UMTS, LTE, LTE-A, and GSM are described in documents from an organization called the Third Generation Partnership Project (3GPP). cdma2000 and UMB are described in documents from an organization named "3rd Generation Partnership Project 2" (3GPP2).
[0047] New Radio (NR) is an emerging wireless communication technology being developed in collaboration with the 5G Technical Forum (5GTF). NR access (e.g., 5G NR) can support a variety of wireless communication services, such as enhanced mobile broadband (eMBB) targeting wide bandwidth (e.g., 80MHz or higher), millimeter wave (mmW) targeting high carrier frequency (e.g., 25GHz or higher), massive machine type communication MTC (mMTC) targeting non-backward compatible MTC technology, and / or mission critical services targeting ultra-reliable low latency communication (URLLC). These services may include latency and reliability requirements. These services may also have different transmission time intervals (TTIs) to meet corresponding quality of service (QoS) requirements. In addition, these services can coexist in the same subframe.
[0048] The techniques described herein may be used for the wireless networks and radio technologies mentioned above as well as other wireless networks and radio technologies. For clarity, although various aspects may be described herein using terms typically associated with 3G and / or 4G wireless technologies, various aspects of the present disclosure may be applied in communication systems based on other generations, such as 5G and later generations, including NR technologies.
[0049] Figure 1 An example wireless communication network 100 is illustrated in which aspects of the present disclosure may be performed. For example, the wireless communication network 100 may be a full-duplex NR system (e.g., a full-duplex 5G network). Figure 1As shown in FIG. 1 , according to various aspects described herein, UE 120a has a BW component 160 that can be configured to adapt an operating BW of UE 120a without incurring a switching delay. For example, using BW component 160, UE 120a can receive an indication of at least one resource BW to be used for communication within an active BWP from a network entity (e.g., a gNB, such as BS 110a). Using BW component 160, UE 120a can perform communication with the network entity on at least one resource BW.
[0050] Similarly, if Figure 1 As shown in , according to various aspects described herein, BS 110a has a BW configuration component 170 that can configure a UE (such as UE 120a) to adapt an operating BW without incurring a switching delay. For example, using the BW configuration component 170, BS 110a can determine a plurality of resource BWs within an active BWP that can be used by a UE (e.g., UE 120a) for communication. Using the BW configuration component 170, BS 110a can signal an indication of at least one of the resource BWs to at least one UE (e.g., UE 120a), and can perform communication with the at least one UE on the at least one resource BW.
[0051] like Figure 1 As illustrated in , the wireless communication network 100 may include several base stations (BS) 110 and other network entities. The BS may be a station that communicates with a user equipment (UE). Each BS 110 may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to the coverage area of a B node (NB) and / or a NB subsystem serving the coverage area, depending on the context in which the term is used. In the NR system, the term "cell" and BS, next generation B node (gNB or g B node), access point (AP), distributed unit (DU), carrier, or transmission reception point (TRP) may be used interchangeably. In some examples, the cell may not necessarily be stationary, and the geographical area of the cell may move according to the location of the mobile BS. In some examples, the BS may be interconnected to each other and / or to one or more other BSs or network nodes (not shown) in the wireless communication network 100 through various types of backhaul interfaces (such as direct physical connections, wireless connections, virtual networks, or analogs using any suitable transmission networks).
[0052] In general, any number of wireless networks may be deployed in a given geographic area. Each wireless network may support a specific radio access technology (RAT) and may operate on one or more frequencies. RAT may also be referred to as radio technology, air interface, etc. Frequency may also be referred to as carrier, subcarrier, frequency channel, frequency modulation, subband, etc. Each frequency may support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.
[0053] A BS may provide communication coverage for macro cells, pico cells, femto cells, and / or other types of cells. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with service subscriptions. A femto cell may cover a relatively small geographic area (e.g., a residence) and may allow restricted access by UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG), UEs of users in a residence, etc.). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In Figure 1 In the example shown in FIG. 1 , BSs 110a, 110b, and 110c may be macro BSs for macro cells 102a, 102b, and 102c, respectively. BS 110x may be a pico BS for pico cell 102x. BSs 110y and 110z may be femto BSs for femto cells 102y and 102z, respectively. A BS may support one or more (e.g., three) cells.
[0054] The wireless communication network 100 may also include a relay station. A relay station is a station that receives transmissions of data and / or other information from an upstream station (e.g., a BS or a UE) and sends transmissions of the data and / or other information to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that relays transmissions for other UEs. Figure 1 In the example shown in , a relay station 110r may communicate with a BS 110a and a UE 120r to facilitate communication between the BS 110a and the UE 120r. A relay station may also be referred to as a relay BS, a relay, or the like.
[0055] The wireless communication network 100 may be a heterogeneous network including different types of BSs (e.g., macro BSs, pico BSs, femto BSs, relays, etc.). These different types of BSs may have different transmit power levels, different coverage areas, and different impacts on interference in the wireless communication network 100. For example, a macro BS may have a high transmit power level (e.g., 20 watts), while a pico BS, a femto BS, and a relay may have a lower transmit power level (e.g., 1 watt).
[0056] The wireless communication network 100 may support synchronous or asynchronous operation. For synchronous operation, each BS may have similar frame timing, and transmissions from different BSs may be roughly aligned in time. For asynchronous operation, each BS may have different frame timing, and transmissions from different BSs may not be aligned in time. The techniques described herein may be used for both synchronous and asynchronous operation.
[0057] A network controller 130 may couple to a set of BSs and provide coordination and control for the BSs. The network controller 130 may communicate with the BSs 110 via a backhaul. The BSs 110 may also communicate with each other (eg, directly or indirectly) via a wireless or wired backhaul.
[0058] UEs 120 (e.g., 120a, 120b, 120x, 120y, etc.) may be dispersed throughout the wireless communication network 100, and each UE may be stationary or mobile. A UE may also be referred to as a mobile station, a terminal, an access terminal, a subscriber unit, a station, a customer premises equipment (CPE), a cellular phone, a smart phone, a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, an appliance, a medical device or medical equipment, a biometric sensor / device, a wearable device (such as a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring, a smart bracelet, etc.)), an entertainment device (e.g., a music device, a video device, a satellite radio, etc.), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing equipment, a global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium. Some UEs may be considered as machine type communication (MTC) devices or evolved MTC (eMTC) devices. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, location tags, etc., which may communicate with a BS, another device (e.g., a remote device), or some other entity. A wireless node may provide connectivity for or to a network (e.g., a wide area network (such as the Internet) or a cellular network), for example, via a wired or wireless communication link. Some UEs may be considered as Internet of Things (IoT) devices, which may be narrowband IoT (NB-IoT) devices.
[0059] Some wireless networks (e.g., LTE) utilize orthogonal frequency division multiplexing (OFDM) on the downlink and single carrier frequency division multiplexing (SC-FDM) on the uplink. OFDM and SC-FDM divide the system bandwidth into multiple (K) orthogonal subcarriers, which are also often referred to as frequency modulation, frequency bins, etc. Each subcarrier can be modulated with data. In general, modulation symbols are sent in the frequency domain for OFDM and in the time domain for SC-FDM. The spacing between adjacent subcarriers can be fixed, and the total number of subcarriers (K) can depend on the system bandwidth. For example, the spacing of subcarriers can be 15kHz, and the minimum resource allocation (called a "resource block" (RB)) can be 12 subcarriers (or 180kHz). Therefore, for system bandwidths of 1.25, 2.5, 5, 10, or 20 megahertz (MHz), the nominal fast Fourier transform (FFT) size can be equal to 128, 256, 512, 1024, or 2048, respectively. The system bandwidth may also be divided into subbands. For example, a subband may cover 1.08 MHz (e.g., 6 RBs), and for a system bandwidth of 1.25, 2.5, 5, 10, or 20 MHz, there may be 1, 2, 4, 8, or 16 subbands, respectively. In LTE, the basic transmission time interval (TTI) or packet duration is a 1 ms subframe. In NR, a subframe is still 1 ms, but the basic TTI is called a slot. A subframe contains a variable number of slots (e.g., 1, 2, 4, 8, 16... slots), depending on the subcarrier spacing (SCS). NR RBs are 12 consecutive frequency subcarriers. NR may support a base subcarrier spacing of 15 KHz, and other subcarrier spacings may be defined relative to the base subcarrier spacing, e.g., 30 kHz, 60 kHz, 120 kHz, 240 kHz, etc. The symbol and slot lengths scale with the subcarrier spacing. The CP length also depends on the subcarrier spacing.
[0060] NR may utilize OFDM with CP on both uplink and downlink and include support for half-duplex operation using TDD. Beamforming may be supported and beam directions may be dynamically configured. MIMO transmissions with precoding may also be supported. In some examples, MIMO configurations in the DL may support up to 8 transmit antennas (with multi-layer DL transmissions of up to 8 streams) and up to 2 streams per UE. In some examples, multi-layer transmissions of up to 2 streams per UE may be supported. Aggregation of multiple cells may be supported using up to 8 serving cells.
[0061] In some examples, access to the air interface may be scheduled. A scheduling entity (e.g., BS) allocates resources for communication between some or all devices and equipment within its service area or cell. A scheduling entity may be responsible for scheduling, assigning, reconfiguring, and releasing resources for one or more subordinate entities. That is, for scheduled communications, subordinate entities utilize resources allocated by the scheduling entity. A base station is not the only entity that can be used as a scheduling entity. In some examples, a UE may act as a scheduling entity, and may schedule resources for one or more subordinate entities (e.g., one or more other UEs), and other UEs may utilize resources scheduled by the UE for wireless communication. In some examples, a UE may act as a scheduling entity in a peer-to-peer (P2P) network and / or in a mesh network. In a mesh network example, UEs may communicate directly with each other in addition to communicating with a scheduling entity.
[0062] In some examples, two or more subordinate entities (e.g., UEs) may communicate with each other using sidelink signals. Real-world applications of such sidelink communications may include public safety, proximity services, UE-to-network relay, vehicle-to-vehicle (V2V) communications, Internet of Everything (IoE) communications, IoT communications, mission-critical mesh networks, and / or various other suitable applications. Generally, a sidelink signal may refer to a signal that is communicated from one subordinate entity (e.g., UE1) to another subordinate entity (e.g., UE2) without relaying the communication through a scheduling entity (e.g., UE or BS), even if the scheduling entity may be used for scheduling and / or control purposes. In some examples, the sidelink signal may be communicated using a licensed spectrum (unlike wireless local area networks, which typically use an unlicensed spectrum).
[0063] exist Figure 1 In FIG. 1 , a solid line with double arrows indicates desired transmissions between a UE and a serving BS, which is a BS designated to serve the UE on the downlink and / or uplink. A thin dashed line with double arrows indicates potentially interfering transmissions between a UE and a BS.
[0064] Figure 2 BS 110 and UE 120 (eg, in Figure 1 For example, antenna 252, processors 266, 258, 264, and / or controller / processor 280 of UE 120 and / or antenna 234, processors 220, 230, 238, and / or controller / processor 240 of BS 110 may be used to perform the various techniques and methods described herein. Figure 2As shown in FIG. 1 , according to various aspects described herein, the controller / processor 240 of the BS 110 has a BW configuration component 170 that can configure a UE (such as UE 120a) to adapt the operating BW without incurring switching delays. Figure 2 As shown in , the controller / processor 280 of the UE 120 has a BW component 160 that can be configured to adapt the operating BW of the UE 120a without incurring handover delays in accordance with various aspects described herein.
[0065] At BS 110, transmit processor 220 may receive data from data source 212 and control information from controller / processor 240. The control information may be for a physical broadcast channel (PBCH), a physical control format indicator channel (PCFICH), a physical hybrid ARQ indicator channel (PHICH), a physical downlink control channel (PDCCH), a group common PDCCH (GC PDCCH), etc. Data may be for a physical downlink shared channel (PDSCH), etc. Processor 220 may process (e.g., encode and symbol map) data and control information to obtain data symbols and control symbols, respectively. Transmit processor 220 may also generate reference symbols (such as for a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a cell-specific reference signal (CRS)). Transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on data symbols, control symbols, and / or reference symbols, where applicable, and may provide output symbol streams to modulators (MODs) 232a-232t. Each modulator 232 may process a respective output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator may further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. The downlink signals from modulators 232a-232t may be transmitted via antennas 234a-234t, respectively.
[0066] At the UE 120, antennas 252a-252r may receive downlink signals from the BS 110 and may provide received signals to demodulators (DEMODs) 254a-254r in the transceiver, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) a respective received signal to obtain input samples. Each demodulator may further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. A MIMO detector 256 may obtain received symbols from all demodulators 254a-254r, perform MIMO detection on the received symbols where applicable, and provide detected symbols. A receive processor 258 may process (e.g., demodulate, deinterleave, and decode) the detected symbols, provide decoded data for the UE 120 to a data sink 260, and provide decoded control information to a controller / processor 280.
[0067] On the uplink, at the UE 120, the transmit processor 264 may receive and process data from a data source 262 (e.g., data for a physical uplink shared channel (PUSCH)) and control information from a controller / processor 280 (e.g., control information for a physical uplink control channel (PUCCH)). The transmit processor 264 may also generate reference symbols for a reference signal (e.g., a sounding reference signal (SRS)). The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266, if applicable, further processed by a demodulator 254a-254r in the transceiver (e.g., for SC-FDM, etc.), and transmitted to the base station 110. At the BS 110, the uplink signal from the UE 120 may be received by the antenna 234, processed by the modulator 232, detected by the MIMO detector 236, if applicable, and further processed by the receive processor 238 to obtain decoded data and control information sent by the UE 120. Receive processor 238 may provide decoded data to data sink 239 and decoded control information to controller / processor 240 .
[0068] Controllers / processors 240 and 280 may direct the operation at BS 110 and UE 120, respectively. Controller / processor 240 and / or other processors and modules at BS 110 may perform or direct the operation of Fig.16 The controller / processor 280 and / or other processors and modules at the UE 120 may perform or direct the execution of operations 1600 in the embodiment and / or other processes for the techniques described herein. Fig.151500 and / or for execution of other processes for the techniques described herein. Memories 242 and 282 may store data and program codes for BS 110 and UE 120, respectively. Scheduler 244 may schedule UEs for data transmission on the downlink and / or uplink.
[0069] Figure 3 300 is a diagram showing an example of a frame format for NR. The transmission timeline of each of the downlink and uplink may be divided into units of radio frames. Each radio frame may have a predetermined duration (e.g., 10 ms) and may be divided into 10 subframes with indices 0 to 9, each subframe being 1 ms. Each subframe may contain a variable number of slots (e.g., 1, 2, 4, 8, 16, ... slots), depending on the SCS. Each slot may include a variable number of symbol periods (e.g., 7, 12, or 14 symbols), depending on the SCS. An index may be assigned to the symbol period in each slot. The subslot structure may refer to a transmission time interval having a duration less than a slot (e.g., 2, 3, or 4 symbols). Each symbol in a slot may be configured as a link direction (e.g., DL, UL, or flexible) for data transmission, and the link direction for each subframe may be dynamically switched. The link direction may be based on the slot format. Each time slot may include DL / UL data and DL / UL control information.
[0070] In NR, synchronization signal blocks (SS) are transmitted. In certain aspects, each SSB may be transmitted in a burst, where each SSB in the burst corresponds to a different beam direction for UE-side beam management (e.g., including beam selection and / or beam refinement). The SSB includes the PSS, SSS, and a two-symbol PBCH. The SSB may be transmitted at a fixed time slot position (such as Figure 3 ) is transmitted in the codewords 0-3 shown in . PSS and SSS can be used by UE for cell search and acquisition. PSS can provide half-frame timing, and SS can provide CP length and frame timing. PSS and SSS can provide cell identity. PBCH carries some basic system information, such as downlink system bandwidth, timing information within radio frames, SS burst set periodicity, system frame number, etc. SSB can be organized into SS bursts to support beam sweeping. Further system information (such as remaining minimum system information (RMSI), system information block (SIB), other system information (OSI)) can be transmitted on the physical downlink shared channel (PDSCH) in certain subframes. SSB can be transmitted up to 64 times, for example, up to 64 different beam directions for millimeter waves. Multiple transmissions of SSB are called SS burst sets. SSBs in an SS burst set can be transmitted in the same frequency region, while SSBs in different SS burst sets can be transmitted in different frequency regions.
[0071] The fifth generation (5G) wireless network sets out the goal of providing ultra-high data rates and supporting a wide range of application scenarios. Wireless full-duplex (FD) communication is an emerging technology and is theoretically capable of doubling the link capacity compared to half-duplex communication. The main idea of wireless full-duplex communication is to enable radio network nodes to transmit and receive simultaneously at the same frequency in the same time slot. This is in contrast to traditional half-duplex operation where transmission and reception are different in time or frequency.
[0072] According to certain aspects, the wireless communication system can support various FD communication modes. For example, Figure 4A The FD communication mode with a FDBS (e.g., gNB1) and a HD UE (e.g., UE) is explained. Figure 4A In the example, the FD BS can communicate with two half-duplex terminals (i.e., UE1 and UE2) simultaneously in UL and DL using the same radio resources. Here, the FD BS may be susceptible to self-interference from its downlink-to-uplink operation and interference from other gNBs (e.g., gNB2). Similarly, the HDUE (e.g., UE1) may be susceptible to interference from other gNBs (e.g., gNB2) and interference from other UEs (e.g., UE2).
[0073] Figure 4B Another FD communication mode with a FD gNB (e.g., gNB1) and a FD UE (e.g., UE1) is illustrated. Figure 4B In the FD gNB, the FD UE and the FD gNB can communicate with each other simultaneously in UL and DL using the same radio resources. While communicating, the FD UE may be susceptible to self-interference, interference from other gNBs (e.g., gNB2), and interference from UE2.
[0074] Figure 4C Another FD communication mode with only FD UE (e.g., UE1) is illustrated. Here, the FD UE may communicate with multiple transmit reception points (e.g., multiple BSs, such as gNB1 and gNB2) simultaneously in UL and DL using the same radio resources. In this example, the FD UE may be susceptible to self-interference from UL to DL operation.
[0075] In addition to supporting various FD communication modes (also referred to herein as deployments), a wireless communication system may also support various types of FD operations. For example, Figure 5A The depicted In-Band Full Duplex (IBFD) is a type of FD operation where devices can transmit and receive on the same time and frequency resources. Figure 5AAs shown in 510 of FIG. 5 , in one aspect, the DL and UL may completely share the same IBFD time / frequency resources (eg, the DL and UL allocations within the IBFD time / frequency resources may completely overlap). Figure 5A As shown in 520, in one aspect, the DL and UL may partially share the same IBFD time / frequency resources (eg, the DL and UL allocations within the IBFD time / frequency resources may partially overlap).
[0076] Figure 5B Sub-band full duplex (SBFD) (also known as flexible duplex) as shown in is another type of FD operation, where devices can transmit and receive simultaneously on different frequency resources. Figure 5B As shown in , DL resources can be separated from UL resources in the frequency domain by a guard band. Due to the lower leakage, this operation mode reduces the self-interference cancellation requirements of the FD device.
[0077] In some aspects, there may be flexible and cross-UE DL / UL operation (across slots and within slots). Figure 6 An example usage of time / frequency resources for an FD gNB (e.g., gNB1) and HD UEs (e.g., UE2, UE2, and UE3) is illustrated. As shown, there may be simultaneous PDSCH and PUSCH grants for the same subframe / timeslot (for different UEs). For example, during the same subframe / timeslot, there is a PDSCH grant 602 for UE2, a PUSCH grant 604 for UE3, and a PDSCH grant 606 for UE1. Additionally, during the same subframe / timeslot, there is a PDSCH grant 608 for UE2, a PUSCH grant 610 for UE3, and a PDSCH grant 612 for UE1.
[0078] Figure 7 Another example use of time / frequency resources (e.g., example spectrum) for an FD gNB (e.g., gNB1) and an FD UE (e.g., UE2) is illustrated. As shown, Figure 6 In contrast, there may be simultaneous PDSCH and PUSCH grants for the same subframe / timeslot for the same UE (e.g., UE2) and / or different UEs. For example, there may be simultaneous UL and DL grants for a FD UE (e.g., UE2). Here, specifically, there are (i) PDSCH grant 702 and PDSCH grant 704 for the same UE2 in the same subframe / timeslot, and (ii) PDSCH grant 706 for UE1. Additionally, there are (i) PDSCH grant 708 and PDSCH grant 710 for the same UE2 in the same subframe / timeslot, and (ii) PDSCH grant 712 for UE1.
[0079] In current communication systems, switching delays are usually imposed when the UE adapts or changes the operating BWP. However, for FD wireless systems, the network may have to change the BW (and additional UL / DL allocations) from one time slot to another or even within a time slot without incurring such delays. Figure 6 and 7 In , for example, the UE may have to change the UL transmission (or DL reception) BWP between time slots with zero latency.
[0080] Typically, the switching delay associated with the adaptation of the BWP may be defined by a number of time slots (eg, # of time slots). Figure 8 Examples of BWP switching delays for different time slot lengths are illustrated. Fig. 9 As shown in FIG. 1 , when switching from a first BWP 902 (e.g., DL BWP#1) to a second BWP 906 (e.g., DL BWP#2), the BWP switching delay 904 may be applied. However, the switching delay may result in lower spectral efficiency. Accordingly, it may be desirable to provide a technique that enables FD devices (e.g., FD UE, FD BS, etc.) to change the operating BW in a flexible manner with minimal (or even zero) latency.
[0081] Example Bandwidth Operation for Full-Duplex User Equipment
[0082] Various aspects of the present disclosure provide techniques that enable FD devices (e.g., FD UEs) to adapt operating bandwidths with reduced (or zero) latency. More specifically, various aspects provide techniques for defining (or allocating) one or more resource BWs within an active BWP. Each resource BW may have a different configuration (e.g., a different portion of the time / frequency resources of the active BWP). By defining multiple resource BWs within an active BWP in this manner, a UE may switch to a different resource BW without incurring a switching delay. That is, the UE may adapt its operating BW with reduced (or zero) latency.
[0083] Note that the techniques described herein for defining a resource BW within an active BWP may be different from defining a wide BWP and changing DL allocations within the wide BWP. For example, in the latter approach, there may be a waste of allocations because the DL may have to be resource block group (RBG) aligned. Similarly, for the latter approach, it may not be possible to change the allocation for one PDSCH within a slot (e.g., NR typically allows multiple PDSCHs to be configured within a slot, each with a different frequency domain resource allocation (FDRA)). As used herein, a resource BW may also be referred to as a sub-BWP or other terminology.
[0084] In some aspects, the BS may define or configure one or more different resource BWs within the active BWP and dynamically indicate which resource BW to use. Fig.10 An example BWP configuration 1000 is illustrated in which four resource BWs (resource BW1 1004 , resource BW2 1006 , resource BW3 1008 , and resource BW4 1010 ) are defined in an active BWP 1002 , in accordance with certain aspects of the present disclosure.
[0085] Each resource BW 1004, 1006, 1008, and 1010 may be configured for uplink or downlink. In some aspects, the UL resource BW (e.g., the resource BW configured for uplink) may have a different configuration (e.g., frequency configuration) than the DL resource BW (e.g., the resource BW configured for downlink). Each resource BW 1004, 1006, 1008, and 1010 may have an optimized configuration for that resource BW (e.g., RBG). In some aspects, the UL and / or DL resource BWs may be non-overlapping (e.g., Figure 5B SBFD shown in ), partially overlapping (e.g., Figure 5A 520) or completely overlapped (e.g., Figure 5A 510 of ). The resource BWs may be contiguous (e.g., resource BW1 1004, resource BW2 1006, and resource BW4 1010 have contiguous sets of frequency resources) or disjoint (e.g., resource BW3 has disjoint sets of frequency resources). In some cases, the FDRA per resource BW may be determined using a smaller number of bits than the BWP.
[0086] In some aspects, resource BWs (e.g., resource BWs 1004, 1006, 1008, and 1010) within an active BWP (e.g., active BWP 1002) may be radio resource control (RRC) configured (e.g., configured via RRC signaling). In some aspects, an indication of a particular resource BW to use may be dynamically indicated via downlink control information (DCI) signaling.
[0087] In one aspect, the DCI indication may be slot-based. That is, the DCI indication may indicate that all symbols within a slot have a specific resource BW. Fig.11A An example BWP configuration 1100A is illustrated in which a resource BW 1104 is defined within an active BWP 1102. Here, the DCI indication then indicates that all symbols 0-13 within a slot have resource BW 1104, in accordance with certain aspects of the present disclosure.
[0088] In one aspect, the DCI indication may indicate that one or more symbols (within a slot) have a particular resource BW. In one example, the DCI indication may indicate that every N consecutive symbols of one or more slots are configured with a resource BW. Fig. 11B An example BWP configuration 1100B is illustrated in accordance with certain aspects of the present disclosure, wherein a resource BW 1108 (e.g., resource #1) and a resource BW 1110 (e.g., resource #2) are defined within an active BWP 1106. Here, a DCI indication may indicate that symbols 0-4 and symbols 9-13 have resource BW 1110 (e.g., for resource BW 1110, N=5), while symbols 5-8 have resource BW 1108 (e.g., for resource BW 1108, N=4). The size of the bundle (e.g., N) may be, for example, 1, 2, 4, 6, 7, 8, 14, etc. symbols. In one aspect, the DCI indication may indicate a time domain resource assignment (TDRA) per resource BW. For example, the DCI indication may indicate a starting symbol and a length (e.g., a number of consecutive symbols) of each resource BW.
[0089] Aspects also provide techniques to allow wideband HD operation and narrower band FD operation. To do this, the network may have to configure simultaneous UL / DL in the resource BW(s) within the active BWP. In one aspect, to allow simultaneous UL / DL, the network entity may employ PDSCH rate matching and demodulation reference signal (DMRS) puncturing. Fig.12 An example BW configuration 1200 is illustrated in accordance with certain aspects of the present disclosure, wherein PDSCH rate matching and / or DMRS puncturing may be used to allow simultaneous UL / DL in resource BW(s). Here, the BW configuration 1200 includes a DL BWP 1202 and a UL BWP 1204. Resource BW1 1206 is defined within the DL BWP 1202 and may be used for wideband HD operation. Resource BW2 1208 is also defined within the DL BWP 1202 and may be used for FD operation. To enable simultaneous UL / DL operation between resource BWs within an active BWP (e.g., DL BWP 1202), PDSCH in symbols 4-5 and 7-8 may be rate matched, and DMRS in symbol 6 may be punctured, e.g., because they conflict with UL and guard bands as shown. This process may be similar to SSB operation within an active DL BWP.
[0090] In some aspects, RBs that collide with the same UE UL, other UE UL, and guard bands may be punctured to allow simultaneous UL / DL between resource BWs of active BWPs. Fig.13 illustrates an example BW configuration 1300 (eg, similar to Fig.12 In this example, the conflicting resources (eg, set 1360 of RBs) may be punctured due to, for example, conflicts with the same UE UL, other UE ULs, and / or guard bands.
[0091] In some aspects, the symbols within an active BWP may be time division multiplexed (eg, each symbol is either UL or DL) to allow for simultaneous UL / DL. Fig.14 An example BW configuration 1400 is illustrated in which symbols 0-13 are time division multiplexed. That is, for each symbol 0-13, the symbol is either used for UL or used for DL.
[0092] Fig.15 1 is a flow diagram illustrating example operations 1500 for wireless communication in accordance with certain aspects of the present disclosure. Operations 1500 may be performed, for example, by a UE (e.g., such as Figure 1 Operation 1500 may be performed by UE 120 in wireless communication network 100 as shown in FIG. 1500 may be implemented as a processor on one or more processors (e.g., Figure 2 In addition, signal transmission and reception by the UE in operation 1500 may be performed by one or more antennas (e.g., Figure 2 In some aspects, signal transmission and / or reception by the UE may be achieved by obtaining and / or outputting signals via a bus interface of one or more processors (eg, controller / processor 280).
[0093] Operations 1500 may begin at block 1502, where the UE receives from a network entity (e.g., BS 110, such as a gNB) an indication of a first resource BW (e.g., resource BW 1004) to be used for communication among a plurality of resource BWs (e.g., resource BW 1004, resource BW 1006, resource BW 1008, and resource BW 1010) within an active BWP (e.g., active BWP 1002). In some aspects, each of the plurality of resource BWs may have a different frequency resource configuration. At block 1504, the UE performs communication with the network entity on the first resource BW.
[0094] In some aspects, the operations 1500 may further include switching from performing communications on a first resource BW (e.g., resource BW 1004) to performing communications on a second resource BW (e.g., resource BW 1006) of the plurality of resource BWs. Figure 8-9Compared to the depicted BWP switching delay, the UE can switch the second resource BW with reduced (e.g., close to zero) waiting time. In some aspects, the switching time can be lower than a threshold set based on a cyclic prefix (CP) length (e.g., the switching time can be a fraction of the CP length). In this way, various aspects enable the UE to adapt its operating BW without incurring significant switching delays associated with conventional techniques.
[0095] In some aspects, the UE may receive (at 1502) an indication of a first resource BW via DCI signaling. In one aspect, the DCI signaling may indicate a plurality of time slots to be used as the first resource BW (e.g., Fig.11A 1104) time slot (e.g., Fig.11A In another aspect, the DCI signaling may indicate a BW to be used as the first resource (e.g., Fig. 11B 1108) of a resource BW (e.g., Fig. 11B In another aspect, the DCI signaling may indicate the first resource BW (eg, Fig. 11B The start code element of the resource BW 1110 in Fig. 11B The codeword 0 of the BWP configuration 1100B in ) and the number of codewords to be used as the first resource BW from the starting codeword (e.g., N=5).
[0096] In some aspects, operations 1500 may further include receiving an indication of a plurality of resource BWs (e.g., resource BW 1004, resource BW 1006, resource BW 1008, and resource BW 1010) within an active BWP (e.g., active BWP 1002). In one aspect, the indication of the plurality of resource BWs within the active BWP may be received via RRC signaling. In some aspects, at least one resource BW of the plurality of resource BWs may include a disjoint set of frequency resources (e.g., Fig.10 Resources in BW 1008).
[0097] In some aspects, the plurality of resource BWs may include at least one of: (i) one or more resource BWs configured for uplink communication or (ii) one or more resource BWs configured for downlink communication. In some examples, at least one of the resource BWs configured for uplink communication may be non-overlapping relative to at least one of the resource BWs configured for downlink communication. In other examples, at least one of the resource BWs configured for uplink communication may overlap at least partially with at least one of the resource BWs configured for downlink communication.
[0098] In some aspects, operation 1500 may further include receiving from a network entity a configuration for performing simultaneous uplink and downlink operations in a first resource BW and a second resource BW in a plurality of resource BWs. In one aspect, the configuration may indicate that those resources in the first resource BW that conflict with resources of the second resource BW are rate matched or punctured. For example, the resources of the first BW may include a rate matched PDSCH and / or a punctured DMRS.
[0099] In one aspect, the configuration for performing simultaneous uplink and downlink operations may indicate that resources of the first resource BW are allocated to a UE and resources of the second resource BW are allocated to another UE. In one aspect, the configuration for performing simultaneous uplink and downlink operations may indicate that resources of the first resource BW and resources of the second resource BW are allocated to the same UE. In one aspect, the configuration for performing simultaneous uplink and downlink operations may indicate that resources of the first resource BW are time-division multiplexed with resources of the second resource BW.
[0100] Fig.16 1 is a flow diagram illustrating example operations 1600 for wireless communications in accordance with certain aspects of the present disclosure. Operations 1600 may be performed, for example, by a BS (e.g., such as Figure 1 Operation 1600 may be performed by BS 110 in wireless communication network 100 shown in FIG. 1600 may be implemented as a processor on one or more processors (e.g., Figure 2 In addition, signal transmission and reception by the BS in operation 1600 may be performed by, for example, one or more antennas (e.g., Figure 2 In some aspects, signal transmission and / or reception by the BS may be achieved by obtaining and / or outputting signals via a bus interface of one or more processors (eg, controller / processor 240).
[0101] Operations 1600 may begin at block 1602, where the BS determines a plurality of resource BWs (e.g., resource BW 1004, resource BW 1006, resource BW 1008, and resource BW 1010) available for communication by one or more UEs within an active BWP (e.g., active BWP 1002). In some aspects, each of the plurality of resource BWs may have a different frequency resource configuration. At block 1604, the BS signals an indication of a first resource BW (e.g., resource BW 1004) to a first UE among the one or more UEs. At block 1606, the BS performs communication with the first UE on the first resource BW.
[0102] In some aspects, the BS (at 1604) may signal an indication of the first resource BW via DCI signaling. In one aspect, the DCI signaling may indicate a plurality of time slots to be used as the first resource BW (e.g., Fig.11A 1104) in a time slot (e.g., Fig.11A In another aspect, the DCI signaling may indicate a BWP configuration 1100A in the first resource BW (eg, Fig. 11B 1108) of a resource BW (e.g., Fig. 11B In another aspect, the DCI signaling may indicate the first resource BW (eg, Fig. 11B The start code element of the resource BW 1110 in Fig. 11B The BWP configuration 1100B in FIG. 11B includes symbol 0 of the BWP configuration 1100B in FIG. 11B and the number of symbols to be used as the first resource BW starting from the starting symbol (eg, N=5).
[0103] In some aspects, operations 1600 may further include signaling an indication of a plurality of resource BWs (e.g., resource BW 1004, resource BW 1006, resource BW 1008, and resource BW 1010) within an active BWP (e.g., active BWP 1002). In one aspect, the indication of the plurality of resource BWs within the active BWP may be signaled via RRC signaling. In some aspects, at least one resource BW of the plurality of resource BWs may include a disjoint set of frequency resources (e.g., Fig.10 Resources in BW 1008).
[0104] In some aspects, the plurality of resource BWs may include at least one of: (i) one or more resource BWs configured for uplink communication or (ii) one or more resource BWs configured for downlink communication. In some examples, at least one of the resource BWs configured for uplink communication may be non-overlapping relative to at least one of the resource BWs configured for downlink communication. In other examples, at least one of the resource BWs configured for uplink communication may overlap at least partially with at least one of the resource BWs configured for downlink communication.
[0105] In some aspects, operation 1600 may further include determining a configuration for performing simultaneous uplink and downlink operations in a first resource BW and a second resource BW in a plurality of resource BWs. The first resource BW may be configured for a downlink, and the second resource BW may be configured for an uplink. Operation 1600 may further include signaling an indication of the configuration to the first UE.
[0106] In one aspect, the configuration may indicate that those resources of the first resource BW that collide with resources of the second resource BW are rate matched or punctured.For example, the resources of the first resource BW may include rate matched PDSCH and / or punctured DMRS.
[0107] In one aspect, the configuration may indicate that the resources of the first resource BW are allocated to a UE and the resources of the second resource BW are allocated to another UE. In one aspect, the configuration may indicate that the resources of the first resource BW and the resources of the second resource BW are allocated to the same UE. In one aspect, the configuration may indicate that the resources of the first resource BW and the resources of the second resource BW are time-division multiplexed.

[0166] The various operations of the methods described above may be performed by any suitable device capable of performing the corresponding functions. These devices may include various hardware and / or software components and / or modules, including but not limited to circuits, application specific integrated circuits (ASICs), or processors. Generally, where there are operations illustrated in the accompanying drawings, these operations may have corresponding paired device-plus-function components with similar numbers.
[0167] The various illustrative logical blocks, modules, and circuits described in conjunction with the present disclosure may be implemented or executed with a general purpose processor, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic device (PLD), discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described herein. A general purpose processor may be a microprocessor, but in the alternative, the processor may be any commercially available processor, controller, microcontroller, or state machine. The processor may also be implemented as a combination of computing devices, for example, a combination of a DSP and a microprocessor, a plurality of microprocessors, one or more microprocessors in conjunction with a DSP core, or any other such configuration.
[0168] If implemented in hardware, an example hardware configuration may include a processing system in a wireless node. The processing system may be implemented using a bus architecture. Depending on the specific application and overall design constraints of the processing system, the bus may include any number of interconnecting buses and bridges. The bus may link together various circuits including a processor, a machine-readable medium, and a bus interface. The bus interface may be used to connect a network adapter, etc., to the processing system via the bus. The network adapter may be used to implement the signal processing functions of the PHY layer. In the user terminal 120 (see Figure 1 ), a user interface (e.g., a keypad, display, mouse, joystick, etc.) may also be connected to the bus. The bus may also link various other circuits, such as timing sources, peripherals, voltage regulators, power management circuits, and the like, which are well known in the art and will not be described further. The processor may be implemented with one or more general and / or special purpose processors. Examples include microprocessors, microcontrollers, DSP processors, and other circuit systems capable of executing software. Those skilled in the art will recognize how to best implement the functionality described with respect to the processing system, depending on the specific application and the overall design constraints imposed on the overall system.
[0169] If implemented in software, each function may be stored on or transmitted by a computer-readable medium as one or more instructions or codes. Software should be broadly interpreted to mean instructions, data, or any combination thereof, whether referred to as software, firmware, middleware, microcode, hardware description language, or other. Computer-readable media include both computer storage media and communication media, which include any media that facilitate the transfer of computer programs from one place to another. The processor may be responsible for managing the bus and general processing, including executing software modules stored on a machine-readable storage medium. A computer-readable storage medium may be coupled to a processor so that the processor can read and write information from / to the storage medium. In an alternative, a storage medium may be integrated into a processor. As an example, a machine-readable medium may include a transmission line, a carrier modulated by data, and / or a computer-readable storage medium having instructions stored thereon that is separated from a wireless node, all of which may be accessed by a processor through a bus interface. Alternatively or additionally, a machine-readable medium or any part thereof may be integrated into a processor, such as a cache and / or a general register file, which may be the case. As an example, examples of machine-readable storage media may include RAM (random access memory), flash memory, ROM (read only memory), PROM (programmable read only memory), EPROM (erasable programmable read only memory), EEPROM (electrically erasable programmable read only memory), registers, magnetic disks, optical disks, hard drives, or any other suitable storage media, or any combination thereof. Machine-readable media may be implemented in a computer program product.
[0170] A software module may include a single instruction, or many instructions, and may be distributed over several different code segments, distributed between different programs, and distributed across multiple storage media. A computer-readable medium may include several software modules. These software modules include instructions that cause a processing system to perform various functions when executed by an apparatus such as a processor. These software modules may include a transmission module and a receiving module. Each software module may reside in a single storage device or may be distributed across multiple storage devices. As an example, when a triggering event occurs, a software module may be loaded into a RAM from a hard drive. During the execution of a software module, a processor may load some instructions into a cache to increase access speed. One or more cache lines may then be loaded into a general register file for execution by the processor. When describing the functionality of a software module as described below, it will be understood that such functionality is implemented by the processor when the processor executes instructions from the software module.
[0171] Likewise, any connection is properly termed a computer-readable medium. For example, if the software is transmitted from a website, server, or other remote source using a coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL), or wireless technology (such as infrared (IR), radio, and microwave), then the coaxial cable, fiber optic cable, twisted pair, DSL, or wireless technology (such as infrared, radio, and microwave) is included in the definition of medium. Disk and disc, as used herein, include compact disc (CD), laser disc, optical disc, digital versatile disc (DVD), floppy disk, and Disks, where disks often reproduce data magnetically, and discs reproduce data optically with lasers. Thus, in some aspects, computer-readable media may include non-transitory computer-readable media (e.g., tangible media). Additionally, for other aspects, computer-readable media may include transient computer-readable media (e.g., signals). Combinations of the above should also be included within the scope of computer-readable media.
[0172] Thus, some aspects may include a computer program product for performing the operations presented herein. For example, such a computer program product may include a computer-readable medium having instructions stored (and / or encoded) thereon, which instructions can be executed by one or more processors to perform the operations described herein. For example, for performing the operations described herein and in Figure 15-16 Instructions for the operations explained in .
[0173] In addition, it should be appreciated that modules and / or other appropriate means for performing the methods and techniques described herein may be downloaded and / or otherwise obtained by a user terminal and / or base station where applicable. For example, such a device can be coupled to a server to facilitate the transfer of means for performing the methods described herein. Alternatively, the various methods described herein can be provided via a storage device (e.g., RAM, ROM, a physical storage medium such as a compact disc (CD) or a floppy disk, etc.) so that once the storage device is coupled to or provided to a user terminal and / or base station, the device can obtain the various methods. In addition, any other suitable technology suitable for providing the methods and techniques described herein to a device may be utilized.
[0174] It will be understood that the claims are not limited to the precise configuration and components illustrated above.
