Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This patent application claims priority to and the benefit of pending Greek patent application No. 20200100420, filed on July 16, 2020, entitled “SCHEDULING FOR ACTIVE BANDWIDTH PARTS,” which patent application is assigned to the assignee of this application and is expressly incorporated herein by reference as if fully set forth below for all applicable purposes. Technical Field

[0003] The techniques discussed below relate generally to wireless communication networks, and more particularly, to sending scheduling information over an active bandwidth portion, where the scheduling information schedules communications over one or more active bandwidth portions. Background Art

[0004] In wireless communication systems, such as those specified under the 5G New Radio (NR) standard, base stations and user equipment (UE) can utilize beamforming to compensate for high path loss and short distances. Beamforming is a signal processing technique used with antenna arrays to enable directional signal transmission and / or reception. Each antenna in the antenna array transmits a signal that is combined with other signals from other antennas in the same array, so that signals at specific angles experience constructive interference, while other signals experience destructive interference.

[0005] The base station and the UE can select at least one beam pair link (BPL) for downlink and / or uplink communication between the base station and the UE. Each BPL includes a transmit beam and a receive beam at the base station and the UE, respectively. For example, on the downlink, the BPL includes a transmit beam at the base station and a receive beam at the UE. To increase data rates, multiple BPLs can be used to facilitate spatial multiplexing of multiple data streams from the base station to the UE.

[0006] In order to reduce latency and improve spectral efficiency within a cell, full-duplex (FD) communication can be used in 5G systems. In some examples, FD allows simultaneous two-way communication by using spatial multiplexing. In the case of FD using spatial multiplexing, different antenna arrays (e.g., different antenna panels) and beams can operate simultaneously, but FD simultaneous communication can still be achieved by spatial separation (e.g., such as by beam direction). The downlink and uplink frequency bands in FD communication can completely overlap, partially overlap, or be separated by a guard band therebetween. Summary of the Invention

[0041] The detailed description described below in conjunction with the accompanying drawings is intended to describe various configurations and is not intended to represent only configurations in which the concepts described herein may be practiced. The detailed description includes specific details for the purpose of providing a thorough understanding of the various concepts. However, it will be apparent to those skilled in the art that these concepts may be practiced without these specific details. In some cases, to avoid confusion between the concepts, well-known structures and components are shown in block diagram form.

[0042] Although various aspects and examples are described in this application by way of illustration of some examples, it will be understood by those skilled in the art that additional implementations and use cases can be implemented in a variety of different arrangements and scenarios. The innovations described herein can be implemented across a variety of different platform types, devices, systems, shapes, sizes, and packaging arrangements. For example, various aspects and / or uses can be implemented via integrated chip examples and other devices based on non-module components (e.g., end-user devices, vehicles, communication devices, computing devices, industrial devices, retail / purchasing devices, medical devices, artificial intelligence-enabled (AI-enabled) devices, etc.). Although some examples may or may not be specifically targeted at use cases or applications, a variety of applicability of the described innovations may occur. The range of implementations can range from chip-level or modular components to non-modular, non-chip-level implementations, and further to integrated, distributed, or original equipment manufacturer (OEM) devices or systems that incorporate one or more aspects of the described innovations. In some actual settings, the devices incorporating the various aspects and features described may also have to include additional components and features for implementing and practicing the claimed and described examples. For example, the transmission and reception of wireless signals must include multiple components for both analog and digital purposes (e.g., hardware components including antennas, radio frequency (RF) chains, power amplifiers, modulators, buffers, processors, interleavers, adders / summers, etc.). It is intended that the innovations described herein can be practiced in a variety of devices, chip-level components, systems, distributed arrangements, end-user devices, etc., of various sizes, shapes, and configurations.

[0043] In some aspects, the present disclosure relates to wireless communications using multiple active bandwidth parts (BWPs). For example, a base station may configure a user equipment (UE) with two or more active BWPs. The UE may then use the multiple active BWPs for full-duplex communication and / or to improve switching time from one active bandwidth part (BWP) to another.

[0044] In some aspects, the present disclosure relates to sending scheduling information on an active BWP, wherein the scheduling information schedules communications on one or more active BWPs. In some examples, a base station may send an indication to a UE specifying whether a scheduled physical downlink shared channel (PDSCH) is carried in one active BWP or in two active BWPs. In some examples, a base station may send an indication to a UE specifying at least one time domain resource allocation (TDRA) for one or more active BWPs. In some examples, a base station may send an indication to a UE specifying at least one frequency domain resource allocation (FDRA) for one or more active BWPs.

[0045] The various concepts presented in this disclosure can be implemented in a variety of telecommunication systems, network architectures, and communication standards. Figure 1 By way of illustrative example and not limitation, various aspects of the present disclosure are described with reference to a wireless communication system 100. The wireless communication system 100 includes three interacting domains: a core network 102, a radio access network (RAN) 104, and a user equipment (UE) 106. By means of the wireless communication system 100, the UE 106 can be enabled for data communication with an external data network 110, such as (but not limited to) the Internet.

[0046] The RAN 104 may implement any suitable wireless communication technology or technologies to provide radio access to the UE 106. As an example, the RAN 104 may operate in accordance with the 3rd Generation Partnership Project (3GPP) New Radio (NR) specifications, commonly referred to as 5G. As another example, the RAN 104 may operate under a mix of 5G NR and Evolved Universal Terrestrial Radio Access Network (eUTRAN) standards, commonly referred to as Long Term Evolution (LTE). 3GPP refers to such a hybrid RAN as the Next Generation RAN, or NG-RAN. In another example, the RAN 104 may operate in accordance with both the LTE and 5G NR standards. Of course, numerous other examples may be utilized within the scope of the present disclosure.

[0047] As shown, RAN 104 includes multiple base stations 108. Broadly speaking, a base station is a network element in a radio access network that is responsible for transmitting or receiving radio signals to or from a UE in one or more cells. In different technologies, standards, or contexts, a base station may be referred to by those skilled in the art as a base transceiver station (BTS), a radio base station, a radio transceiver, a transceiver function, a basic service set (Bss), an extended service set (ESS), an access point (AP), a node B (NB), an eNode B (eNB), a gNode B (gNB), a transmit and receive point (TRP), or some other suitable terminology. In some examples, a base station may include two or more TRPs that may be co-located or non-co-located. Each TRP may communicate in the same or different frequency bands and on the same or different carrier frequencies. In an example where RAN 104 operates according to both LTE and 5G NR standards, one of the base stations 108 may be an LTE base station, while the other may be a 5G NR base station.

[0048] The radio access network 104 is further shown to support wireless communications for multiple mobile devices. In the 3GPP standards, a mobile device may be referred to as a user equipment (UE) 106, but may also be referred to by those skilled in the art as a mobile station (MS), a subscriber station, a mobile unit, a subscriber unit, a wireless unit, a remote unit, a mobile device, a wireless device, a wireless communication device, a remote device, a mobile subscriber station, an access terminal (AT), a mobile terminal, a wireless terminal, a remote terminal, a handheld device, a terminal, a user agent, a mobile client, a client, or some other suitable terminology. The UE 106 may be a device that provides network service access to a user. In an example where the RAN 104 operates according to both LTE and 5G NR standards, the UE 106 may be an Evolved Universal Terrestrial Radio Access Network - New Radio Dual Connectivity (EN-DC) UE capable of simultaneously connecting to an LTE base station and an NR base station to receive data packets from both the LTE base station and the NR base station.

[0049] In this document, a mobile device does not necessarily have the ability to move, but can be stationary. The term mobile device or mobile equipment refers broadly to a variety of devices and technologies. A UE may include a number of hardware structural components whose size, shape, and arrangement facilitate communication; such components may include antennas, antenna arrays, RF chains, amplifiers, one or more processors, etc. electrically coupled to each other. For example, some non-limiting examples of mobile devices include mobile phones, cellular phones (handsets), smart phones, Session Initiation Protocol (SIP) phones, laptops, personal computers (PCs), notebooks, netbooks, smartbooks, tablet computers, personal digital assistants (PDAs), and various embedded systems, such as those corresponding to the Internet of Things (IoT).

[0050] Mobile devices may also be cars or other transportation vehicles, remote sensors or actuators, robots or robotic devices, satellite radios, global positioning system (GPS) devices, object tracking devices, drones, multirotors, quadcopters, remote control devices, consumer and / or wearable devices such as glasses, wearable cameras, virtual reality devices, smart watches, health or fitness trackers, digital audio players (e.g., MP3 players), cameras, game consoles, etc. Mobile devices may also be digital home or smart home devices such as home audio, video, and / or multimedia devices, appliances, vending machines, smart lighting, home security systems, smart meters, etc. Mobile devices may also be smart energy devices, security devices, solar panels or solar arrays, municipal infrastructure devices that control electricity, lighting, water, etc. (e.g., smart grids), industrial automation and enterprise devices, logistics controllers, agricultural equipment, etc. In addition, mobile devices may provide connected medical or telemedicine support, i.e., remote healthcare. Remote health devices may include remote health monitoring devices and remote health management devices, whose communications may be given priority treatment or priority access over other types of information, for example, in terms of priority access and / or associated QoS for the transmission of critical service data.

[0051] The wireless communication between RAN 104 and UE 106 can be described as utilizing an air interface. Transmissions from a base station (e.g., base station 108) to one or more UEs (e.g., UE 106) over the air interface can be referred to as downlink (DL) transmissions. In some examples, the term downlink can refer to point-to-multipoint transmissions originating from a base station (e.g., base station 108). Another way to describe this point-to-multipoint transmission scheme can be to use the term broadcast channel multiplexing. Transmissions from a UE (e.g., UE 106) to a base station (e.g., base station 108) can be referred to as uplink (UL) transmissions. In some examples, the term uplink can refer to point-to-point transmissions originating from a UE (e.g., UE 106).

[0052] In some examples, access to the air interface can be scheduled, where a scheduling entity (e.g., base station 108) allocates resources for communications between some or all devices and equipment within its service area or cell. In the present disclosure, as discussed further below, a scheduling entity can be responsible for scheduling, assigning, reconfiguring, and releasing resources for one or more scheduled entities (e.g., UEs). That is, for scheduled communications, multiple UEs 106, which can be scheduled entities, can utilize resources allocated by the scheduling entity (e.g., base station 108).

[0053] Base station 108 is not the only entity that can serve as a scheduling entity. That is, in some examples, a UE can act as a scheduling entity, scheduling resources for one or more scheduled entities (e.g., one or more other UEs). For example, a UE can communicate with other UEs in a peer-to-peer or device-to-device manner and / or in a relay configuration.

[0054] like Figure 1 As shown, a scheduling entity (e.g., base station 108) can broadcast downlink traffic 112 to one or more scheduled entities (e.g., UE 106). Broadly speaking, a scheduling entity is a node or device responsible for scheduling traffic in a wireless communication network (including downlink traffic 112 and, in some examples, uplink traffic 116 and / or uplink control information 118 from one or more scheduled entities to the scheduling entity). On the other hand, a scheduled entity is a node or device that receives downlink control information 114 (including, but not limited to, scheduling information (e.g., grants), synchronization or timing information, or other control information from another entity in the wireless communication network (such as a scheduling entity)).

[0055] In addition, uplink and / or downlink control information and / or traffic information can be divided into frames, subframes, time slots and / or symbols in time. As used herein, a symbol can refer to a time unit in which each subcarrier carries a resource element (RE) in an orthogonal frequency division multiplexing (OFDM) waveform. In some examples, a time slot can carry 7 or 14 OFDM symbols. A subframe can refer to a duration of 1 millisecond (ms). Multiple subframes or time slots can be grouped together to form a single frame or radio frame. In the present disclosure, a frame can refer to a predetermined duration (e.g., 10ms) for wireless transmission, with each frame consisting of, for example, 10 subframes of 1ms. Of course, these definitions are not required, and any suitable scheme for organizing a waveform can be utilized, and the various time divisions of a waveform can have any suitable duration.

[0056] Generally, base stations 108 may include a backhaul interface for communicating with a wireless communication system's backhaul 120. Backhaul 120 may provide a link between base stations 108 and core network 102. Furthermore, in some examples, a backhaul network may provide interconnections between base stations 108. Various types of backhaul interfaces may be employed, such as a direct physical connection using any suitable transport network, a virtual network, and the like.

[0057] The core network 102 can be part of the wireless communication system 100 and can be independent of the radio access technology used in the RAN 104. In some examples, the core network 102 can be configured according to 5G standards (e.g., 5GC). In other examples, the core network 102 can be configured according to 4G Evolved Packet Core (EPC) or any other suitable standard or configuration.

[0058] Now refer to Figure 2 , by way of example and not limitation, a schematic diagram of a radio access network (RAN) 200 is provided. In some examples, the RAN 200 may be similar to the one described above and in Figure 1 The RAN 104 is the same as shown in FIG.

[0059] The geographic area covered by the RAN 200 may be divided into cellular areas (cells) that may be uniquely identified by a user equipment (UE) based on an identity broadcast from an access point or base station. Figure 2 Cells 202, 204, 206, and 208 are shown, each of which may include one or more sectors (not shown). A sector is a sub-area of ​​a cell. All sectors within a cell are served by the same base station. A radio link within a sector may be identified by a single logical identifier belonging to that sector. In a cell divided into sectors, multiple sectors within the cell may be formed by antenna groups, with each antenna responsible for communicating with UEs in that portion of the cell.

[0060] Various base station arrangements can be utilized. For example, Figure 2 , two base stations 210 and 212 are shown in cells 202 and 204; and base station 214 is shown as controlling remote radio head (RRH) 216 in cell 206. That is, the base stations may have integrated antennas or may be connected to antennas or RRHs via feeder cables. In the example shown, cells 202, 204, and 206 may be referred to as macro cells because base stations 210, 212, and 214 support cells having large sizes. Additionally, base station 218 is shown in cell 208, which may overlap with one or more macro cells. In this example, cell 208 may be referred to as a small cell (e.g., a micro cell, pico cell, femto cell, home base station, home node B, home eNode B, etc.) because base station 218 supports cells having relatively small sizes. Cell size may be determined based on system design and component constraints.

[0061] It should be understood that the RAN 200 may include any number of wireless base stations and cells. In addition, relay nodes may be deployed to extend the size or coverage area of ​​a given cell. Base stations 210, 212, 214, 218 provide wireless access points to the core network for any number of mobile devices. In some examples, base stations 210, 212, 214, and / or 218 may be similar to those described above and in Figure 1 The base station / scheduling entity shown in is the same.

[0062] Figure 2 Also included is an unmanned aerial vehicle (UAV) 220, which can be a drone or a quadcopter. UAV 220 can be configured to function as a base station, or more specifically, as a mobile base station. That is, in some examples, the cell is not necessarily stationary, and the geographic area of ​​the cell can move depending on the location of a mobile base station (such as UAV 220).

[0063] Within the RAN 200, cells may include UEs that may communicate with one or more sectors of each cell. In addition, each base station 210, 212, 214, and 218 may be configured to provide connectivity to the core network 102 (see FIG. 1 ) for all UEs in the respective cell. Figure 1 ) access point. For example, UEs 222 and 224 can communicate with base station 210; UEs 226 and 228 can communicate with base station 212; UEs 230 and 232 can communicate with base station 214 through RRH 216; and UE 234 can communicate with base station 218. In some examples, UEs 222, 224, 226, 228, 230, 232, 234, 236, 238, 240, and / or 242 can communicate with the base stations described above and in Figure 1 In some examples, UAV 220 (e.g., a quadcopter) can be a mobile network node and can be configured to function as a UE. For example, UAV 220 can operate within cell 202 by communicating with base station 210.

[0064] In another aspect of the RAN 200, sidelink signals can be used between UEs without relying on scheduling or control information from a base station. For example, sidelink communications can be utilized in device-to-device (D2D) networks, peer-to-peer (P2P) networks, vehicle-to-vehicle (V2V) networks, vehicle-to-everything (V2X) networks, and / or other suitable sidelink networks. For example, two or more UEs (e.g., UEs 238, 240, and 242) can use sidelink signals 237 to communicate with each other without relaying the communications through a base station. In some examples, UEs 238, 240, and 242 can each act as a scheduling entity or transmitting sidelink device and / or a scheduled entity or receiving sidelink device to schedule resources and communicate sidelink signals 237 between them without relying on scheduling or control information from a base station. In other examples, two or more UEs (e.g., UEs 226 and 228) within the coverage area of ​​a base station (e.g., base station 212) may also communicate sidelink signals 227 via a direct link (sidelink) without passing the communication through base station 212. In this example, base station 212 may allocate resources to UEs 226 and 228 for the sidelink communication.

[0065] In the RAN 200, the ability of a UE to communicate independently of its location while moving is called mobility. The various physical channels between the UE and the radio access network are typically managed by an access and mobility management function (AMF, not shown). Figure 1 The AMF is established, maintained and released under the control of the core network 102), and the AMF may include a security context management function (SCMF) that manages security contexts for both control plane functions and user plane functions, and a security anchor function (sEAF) that performs authentication.

[0066] RAN 200 can utilize DL-based mobility or UL-based mobility to implement mobility and handover (i.e., transferring the UE's connection from one radio channel to another). In a network configured for DL-based mobility, during a call with a scheduling entity or at any other time, the UE can monitor various parameters of the signal from its serving cell and various parameters of neighboring cells. Depending on the quality of these parameters, the UE can maintain communication with one or more neighboring cells. During this time, if the UE moves from one cell to another, or if the signal quality from a neighboring cell exceeds the signal quality from the serving cell for a given amount of time, the UE can perform a handoff or handover from the serving cell to the neighboring (target) cell. For example, UE 224 (shown as a carrier, although any suitable form of UE may be used) can move from the geographic area corresponding to its serving cell (e.g., cell 202) to the geographic area corresponding to a neighboring cell (e.g., cell 206). When the signal strength or quality from a neighboring cell exceeds the signal strength or quality of the serving cell for a given amount of time, UE 224 may send a report message indicating this to its serving base station (e.g., base station 210). In response, UE 224 may receive a handover command, and the UE may proceed with the handover to cell 206.

[0067] In a network configured for UL-based mobility, the UL reference signal from each UE can be used by the network to select a serving cell for each UE. In some examples, base stations 210, 212, and 214 / 216 can broadcast a unified synchronization signal (e.g., a unified primary synchronization signal (PSS), a unified secondary synchronization signal (SSS), and a unified physical broadcast channel (PBCH)). UEs 222, 224, 226, 228, 230, and 232 can receive the unified synchronization signal, derive carrier frequency and slot timing from the synchronization signal, and send an uplink pilot or reference signal in response to the derived timing. The uplink pilot signal sent by a UE (e.g., UE 224) can be received simultaneously by two or more cells within the RAN 200 (e.g., base stations 210 and 214 / 216). Each of the cells can measure the strength of the pilot signal, and the radio access network (e.g., one or more of base stations 210 and 214 / 216 and / or a central node within the core network) can determine the serving cell for UE 224. As the UE 224 moves through the RAN 200, the network may continue to monitor the uplink pilot signals transmitted by the UE 224. When the signal strength or quality of the pilot signals measured by the neighboring cell exceeds the signal strength or quality measured by the serving cell, the RAN 200 may hand over the UE 224 from the serving cell to the neighboring cell with or without notifying the UE 224.

[0068] Although the synchronization signals transmitted by base stations 210, 212, and 214 / 216 may be uniform, the synchronization signals may not identify a specific cell, but may identify a region of multiple cells operating at the same frequency and / or the same timing. The use of these regions in 5G networks or other next-generation communication networks implements an uplink-based mobility framework and improves the efficiency of both the UE and the network because the number of mobility messages that need to be exchanged between the UE and the network can be reduced.

[0069] In various implementations, the air interface in the RAN 200 may utilize licensed spectrum, unlicensed spectrum, or shared spectrum. Licensed spectrum provides exclusive use of a portion of spectrum, typically through a mobile network operator purchasing a license from a government regulatory body. Unlicensed spectrum provides shared use of a portion of spectrum without requiring a government-granted license. While some technical regulations generally still need to be adhered to to access unlicensed spectrum, generally any operator or device can gain access. Shared spectrum may fall somewhere between licensed and unlicensed spectrum, where technical regulations or restrictions may be required to access the spectrum, but the spectrum may still be shared by multiple operators and / or multiple radio access technologies (RATs). For example, a licensee of a licensed portion of spectrum may provide licensed shared access (LSA) to share the spectrum with other parties, e.g., through appropriate licensee-determined conditions to gain access.

[0070] The electromagnetic spectrum is typically subdivided into various categories, bands, channels, etc. based on frequency / wavelength. In 5GNR, two initial operating bands have been identified for the frequency range designation FRI (410 MHz-7.125 GHz) and FR2 (24.25 GHz-52.6 GHz). It should be understood that although a portion of FR1 is greater than 6 GHz, FR1 is often referred to (interchangeably) as a "sub-6 GHz" band in various documents and articles. FR2 sometimes presents a similar naming issue, although it is different from the extremely high frequency (EHF) band (30 GHz-300 GHz) identified as a "millimeter wave" band by the International Telecommunication Union (ITU). However, in various documents and articles, FR2 is often referred to (interchangeably) as a "millimeter wave" band.

[0071] Frequencies between FR1 and FR2 are often referred to as mid-band frequencies. Recent 5G NR research has identified the operating bands for these mid-band frequencies as frequency range designation FR3 (7.125 GHz - 24.25 GHz). Frequency bands falling within FR3 can inherit FR1 characteristics and / or FR2 characteristics, effectively extending the features of FR1 and / or FR2 to mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operation above 52.6 GHz. For example, three higher operating bands have been identified as frequency range designations FR4-a or FR4-1 (52.6 GHz - 71 GHz), FR4 (52.6 GHz - 114.25 GHz), and FR5 (114.25 GHz - 300 GHz). Each of these higher frequency bands falls within the EHF band.

[0072] With the foregoing in mind, unless otherwise specifically stated, it should be understood that the term "sub-6 GHz," etc., as used herein, may broadly refer to frequencies below 6 GHz, which may be within FR1, or which may include mid-band frequencies. Furthermore, unless otherwise specifically stated, it should be understood that the term "millimeter wave," etc., as used herein, may broadly refer to frequencies which may include mid-band frequencies, which may be within FR2, FR4, FR4-a, FR4-1, and / or FR5, or which may be within the EHF band.

[0073] The air interface in the RAN 200 may utilize one or more multiplexing and multiple access algorithms to enable simultaneous communication of various devices. For example, the 5G NR specification utilizes orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) to provide multiple access for UL transmissions from UEs 222 and 224 to the base station 210, and provides multiplexing for DL ​​transmissions from the base station 210 to one or more UEs 222 and 224. In addition, for UL transmissions, the 5G NR specification provides support for discrete Fourier transform-spread-OFDM (DFT-s-OFDM) with CP (also known as single-carrier FDMA (SC-FDMA)). However, within the scope of the present disclosure, multiplexing and multiple access are not limited to the above schemes and may be provided using time division multiple access (TDMA), code division multiple access (CDMA), frequency division multiple access (FDMA), sparse code multiple access (SCMA), resource spread multiple access (RSMA), or other suitable multiple access schemes. Furthermore, DL transmissions from base station 210 to UEs 222 and 224 may be multiplexed using time division multiplexing (TDM), code division multiplexing (CDM), frequency division multiplexing (FDM), orthogonal frequency division multiplexing (OFDM), sparse code multiplexing (SCM), or other suitable multiplexing schemes.

[0074] The air interface in RAN 200 may further utilize one or more duplexing algorithms. Duplexing refers to a point-to-point communication link in which two endpoints can communicate with each other bidirectionally. Full-duplex means that both endpoints can communicate with each other simultaneously. Half-duplex means that only one endpoint can send information to the other endpoint at a time. Time division duplexing (TDD) is often used to implement half-duplex emulation for wireless links. In TDD, transmissions in different directions on a given channel are separated from each other using time division multiplexing. That is, at some times, the channel is dedicated to transmission in one direction, while at other times, the channel is dedicated to transmission in the other direction, where the direction can change very quickly, for example, several times per time slot. In wireless links, full-duplex channels generally rely on physical isolation between the transmitter and receiver, as well as appropriate interference cancellation techniques. Full-duplex emulation is often implemented for wireless links using frequency division duplexing (FDD) or space division duplexing (SDD). In FDD, transmissions in different directions operate on different carrier frequencies. In SDD, transmissions in different directions on a given channel are separated from each other using space division multiplexing (SDM). In other examples, full-duplex communication can be implemented within an unpaired spectrum (e.g., within a single carrier bandwidth), where transmissions in different directions occur within different sub-bands of the carrier bandwidth. This type of full-duplex communication can be referred to as sub-band full-duplex (SBFD), cross-division duplex (xDD), or flexible duplex.

[0075] Various aspects of the present disclosure will be described with reference to OFDM waveforms, examples of which are shown in Figure 3 Schematically illustrated in FIG. Those skilled in the art will appreciate that various aspects of the present disclosure may be applied to SC-FDMA waveforms in substantially the same manner as described below. That is, while some examples of the present disclosure may focus on OFDM links for clarity, it will be appreciated that the same principles may also be applied to SC-FDMA waveforms.

[0076] Now refer to Figure 3 , shows an expanded view of an example subframe 302, illustrating an OFDM resource grid. However, as those skilled in the art will readily appreciate, the physical (PHY) layer transmission structure for any particular application may differ from the examples described herein, depending on a number of factors. Here, time is in the horizontal direction, in units of OFDM symbols; frequency is in the vertical direction, in units of subcarriers of a carrier.

[0077] Resource grid 304 can be used to schematically represent the time-frequency resources used for a given antenna port. That is, in a multiple-input, multiple-output (MIMO) implementation with multiple available antenna ports, corresponding multiple resource grids 304 can be used for communication. Resource grid 304 is divided into multiple resource elements (REs) 306. An RE is 1 subcarrier x 1 symbol, the smallest discrete portion of the time-frequency grid, and contains a single complex value representing data from a physical channel or signal. Depending on the modulation utilized in a particular implementation, each RE can represent one or more information bits. In some examples, a block of REs can be referred to as a physical resource block (PRB) or more simply as a resource block (RB) 308, which contains any suitable number of consecutive subcarriers in the frequency domain. In one example, an RB can include 12 subcarriers, independent of the numerology used. In some examples, depending on the numerology used, an RB can include any suitable number of consecutive OFDM symbols in the time domain. In this disclosure, it is assumed that a single RB, such as RB 308, corresponds entirely to a single communication direction (either transmit or receive for a given device).

[0078] A collection of contiguous or non-contiguous resource blocks may be referred to herein as a resource block group (RBG), subband, or bandwidth part (BWP). A collection of subbands or BWPs may span the entire bandwidth. Scheduling a scheduled entity (e.g., a UE) for downlink, uplink, or sidelink transmissions typically involves scheduling one or more resource elements 306 within one or more subbands or bandwidth parts (BWPs). Thus, a UE typically utilizes only a subset of the resource grid 304. In some examples, an RB may be the smallest unit of resource that can be allocated to a UE. Therefore, the more RBs scheduled for a UE and the higher the modulation scheme selected for the air interface, the higher the data rate for the UE. RBs may be scheduled by a scheduling entity, such as a base station (e.g., gNB, eNB, etc.), or may be self-scheduled by the UE implementing D2D sidelink communication.

[0079] In this illustration, RB 308 is shown as occupying less than the entire bandwidth of subframe 302, with some subcarriers shown above and below RB 308. In a given implementation, subframe 302 may have a bandwidth corresponding to any number of one or more RBs 308. Furthermore, in this illustration, RB 308 is shown as occupying less than the entire duration of subframe 302, although this is only one possible example.

[0080] Each 1ms subframe 302 may be composed of one or more adjacent time slots. Figure 3In the example shown, as an illustrative example, a subframe 302 includes four time slots 310. In some examples, a time slot can be defined based on a specified number of OFDM symbols with a given cyclic prefix (CP) length. For example, a time slot can include 7 or 14 OFDM symbols with a nominal CP. Additional examples may include mini-slots with shorter durations (e.g., one to three OFDM symbols), which are sometimes referred to as shortened transmission time intervals (TTIs). In some cases, these mini-slots or shortened transmission time intervals (TTIs) may occupy resources scheduled for ongoing time slot transmissions for the same UE or different UEs. Any number of resource blocks can be utilized within a subframe or time slot.

[0081] An expanded view of one of the time slots 310 shows the time slot 310 including a control region 312 and a data region 314. Generally, the control region 312 may carry control channels, while the data region 314 may carry data channels. Of course, a time slot may contain all DL, all UL, or at least one DL portion and at least one UL portion. Figure 3 The structure shown in is only one example, and different slot structures may be utilized and may include one or more of each of the control region and the data region.

[0082] Although not in Figure 3 Although not shown in FIG, various REs 306 within RB 308 may be scheduled to carry one or more physical channels, including control channels, shared channels, data channels, etc. Other REs 306 within RB 308 may also carry pilot or reference signals. These pilot or reference signals may be used by a receiving device to perform channel estimation of the corresponding channels, which may enable coherent demodulation / detection of the control and / or data channels within RB 308.

[0083] In some examples, time slot 310 can be used for broadcast, multicast, groupcast, or unicast communication. For example, broadcast, multicast, or groupcast communication can refer to point-to-multipoint transmission from one device (e.g., a base station, UE, or other similar device) to other devices. Here, broadcast communication is delivered to all devices, while multicast or groupcast communication is delivered to multiple intended recipient devices. Unicast communication can refer to point-to-point transmission from one device to a single other device.

[0084] In an example of cellular communication via a cellular carrier via a Uu interface, for DL ​​transmission, a scheduling entity (e.g., a base station) may allocate one or more REs 306 (e.g., within a control region 312) to transmit DL control information including one or more DL control channels (e.g., a physical downlink control channel (PDCCH)) to one or more scheduled entities (e.g., UEs). The PDCCH carries downlink control information (DCI), including but not limited to power control commands (e.g., one or more open-loop power control parameters and / or one or more closed-loop power control parameters), scheduling information, grants, and / or RE assignments for DL ​​and UL transmissions. The PDCCH may also carry hybrid automatic repeat request (HARQ) feedback transmissions, such as acknowledgements (ACKs) or negative acknowledgements (NACKs). HARQ is a technique well known to those skilled in the art, in which the integrity of packet transmissions may be checked on the receiving side to ensure accuracy, for example, using any suitable integrity check mechanism (e.g., a checksum or cyclic redundancy check (CRC)). If the integrity of the transmission is confirmed, an ACK may be sent, while if it is not confirmed, a NACK may be sent. In response to the NACK, the transmitting device may send a HARQ retransmission, which may enable chase combining, incremental redundancy, and the like.

[0085] The base station may further allocate one or more REs 306 (e.g., in the control region 312 or the data region 314) for carrying other DL signals, such as a demodulation reference signal (DMRS); a phase tracking reference signal (PT-RS); a channel state information (CSI) reference signal (CSI-RS); and a synchronization signal block (SSB). The SSBs may be broadcast at regular intervals based on a period (e.g., 5, 10, 20, 30, 80, or 130 ms). The SSBs include a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcast control channel (PBCH). The UE may utilize the PSS and SSS to achieve radio frame, subframe, slot, and symbol synchronization in the time domain, identify the center of the channel (system) bandwidth in the frequency domain, and identify the physical cell identity (PCI) of the cell.

[0086] The PBCH in the SSB may also include a master information block (MIB), which includes various system information and parameters for decoding system information blocks (SIBs). The SIB may be, for example, system information type 1 (SIB1), which may include various additional (remaining) system information. Together, the MIB and SIB1 provide minimum system information (SI) for initial access. Examples of system information transmitted in the MIB may include, but are not limited to, subcarrier spacing (e.g., default downlink parameter set), system frame number, configuration of the PDCCH control resource set (CORESET) (e.g., PDCCH CORESET0), cell barred indicator, cell reselection indicator, raster offset, and search space of SIB1. Examples of remaining minimum system information (RMSI) transmitted in SIB1 may include, but are not limited to, random access search space, paging search space, downlink configuration information, and uplink configuration information. The base station may also send other system information (OsI).

[0087] In an UL transmission, a scheduled entity (e.g., a UE) may transmit UL control information (UCI) including one or more UL control channels (e.g., a physical uplink control channel (PUCCH)) to a scheduling entity using one or more REs 306. UCI may include various packet types and categories, including pilots, reference signals, and information configured to enable or assist in decoding uplink data transmissions. Examples of uplink reference signals may include sounding reference signals (SRs) and uplink DMRS. In some examples, UCI may include a scheduling request (SR), i.e., a request to a scheduling entity to schedule an uplink transmission. Here, in response to the SR transmitted on the UCI, the scheduling entity may send downlink control information (DCI) that may schedule resources for uplink packet transmission. UCI may also include HARQ feedback, channel state feedback (CSF), such as a CSI report, or any other suitable UCI.

[0088] In addition to control information, one or more REs 306 (e.g., within the data region 314) may be allocated for data traffic. Such data traffic may be carried on one or more traffic channels, such as, for DL ​​transmissions, on the physical downlink shared channel (PDSCH); or, for UL transmissions, on the physical uplink shared channel (PUSCH). In some examples, one or more REs 306 within the data region 314 may be configured to carry other signals, such as one or more SIBs and DMRS.

[0089] In an example of sidelink communication over a sidelink carrier via a Proximity Services (ProSe) PC5 interface, the control region 312 of a timeslot 310 may include a physical sidelink control channel (PSCCH), which includes sidelink control information (SCI) transmitted by an initiating (transmitting) sidelink device (e.g., a transmitting (Tx) V2X device or other Tx UE) to a set of one or more other receiving sidelink devices (e.g., a receiving (Rx) V2X device or other Rx UE). The data region 314 of the timeslot 310 may include a physical sidelink shared channel (PSSCH), which includes sidelink data traffic transmitted by the initiating (transmitting) sidelink device within resources reserved by the transmitting sidelink device on the sidelink carrier via the SCI. Other information may be further transmitted on each RE 306 within the timeslot 310. For example, HARQ feedback information may be transmitted from the receiving sidelink device to the transmitting sidelink device in a physical sidelink feedback channel (PSFCH) within the timeslot 310. Additionally, one or more reference signals may be transmitted within slot 310, such as a sidelink SSB, a sidelink CSI-RS, a sidelink SRS, and / or a sidelink positioning reference signal (PRS).

[0090] These physical channels are typically multiplexed and mapped onto transport channels for processing at the media access control (MAC) layer. Transport channels carry information blocks called transport blocks (TBs). Based on the modulation and coding scheme (MCS) and the number of RBs in a given transmission, the transport block size (TBS), which can correspond to the number of information bits, can be a controlled parameter.

[0091] References Figure 1-Figure 3 The channels or carriers described are not necessarily all channels or carriers that can be used between the scheduling entity and the scheduled entity, and a person skilled in the art will recognize that other channels or carriers may be used in addition to the channels or carriers shown, such as other traffic, control and feedback channels.

[0092] As described above, the UE and the base station (e.g., gNB) can use full-duplex communication. Figure 4A 、 Figure 4B and Figure 4C 404, a half-duplex UE 406, a first full-duplex UE 412, and a second full-duplex UE 408. The figures further illustrate the half-duplex UE 406, the first full-duplex UE 412, the second full-duplex UE 408, and different interference sources (e.g., cross-beam interference) for different gNB configurations, according to some aspects of the present disclosure. The half-duplex UE 406, the first full-duplex UE 412, and the second full-duplex UE 408 may correspond to Figure 1 、 Figure 2 、 Figure 11 and Figure 12 Any UE or scheduled entity shown in any of the figures.

[0093] exist Figure 4A , a full-duplex gNB 402 (e.g., a scheduling entity) transmits to a half-duplex UE 406. During the time of the transmission from the full-duplex gNB 402 to the half-duplex UE 406, the full-duplex gNB 402 receives self-interference 410 at its receiver (not shown) from its own transmission to the half-duplex UE 406, as well as interference from the neighboring gNB 404 and an uplink transmission from a second full-duplex UE 408. The half-duplex UE 406 also receives interference from the second full-duplex UE 408 and the neighboring gNB 404. Because the half-duplex UE 406 is a half-duplex UE, the half-duplex UE 406 does not transmit during the time of the transmission from the full-duplex gNB 402 to the half-duplex UE 406, and therefore, the half-duplex UE 406 does not receive self-interference. The full-duplex gNB 402 and the neighboring gNB 404 may each correspond to Figure 1 、 Figure 2 、 Figure 7A 、 Figure 11 and Figure 14 Any base station or scheduling entity shown in any of the figures.

[0094] exist Figure 4B , full-duplex gNB 402 sends a downlink transmission to a first full-duplex UE 412. During the time that the downlink transmission is being transmitted from full-duplex gNB 402 to first full-duplex UE 412, full-duplex gNB 402 receives at its receiver (not shown) a simultaneous uplink transmission from first full-duplex UE 412. Concurrently with the just-mentioned simultaneous downlink and uplink transmissions, first full-duplex UE 412 receives at its receiver (not shown) self-interference 414 from its own transmission to full-duplex gNB 402, as well as interference from neighboring gNB 404 and interference from second full-duplex UE 408.

[0095] Figure 4C A full-duplex gNB configured as a multi-TRP base station is shown, including a first TRP 402a and a second TRP 402b. The first TRP 402a is receiving an uplink transmission from a first full-duplex UE 412. During the time when the uplink transmission is being transmitted to the first TRP 402a, the first full-duplex UE 412 is also receiving a transmission from the second TRP 402b. In addition to the transmission received from the second TRP 418b, the first full-duplex UE 412 also receives self-interference 416 at its receiver (not shown) from its own transmission to the first TRP 402a.

[0096] Traditionally, it can be Figure 4A-4B Different frequency bands are allocated for transmission to alleviate the above interference. Figure 4A For a half-duplex UE 406, the interference can be mitigated if the interference from the neighboring gNB 404 and the second full-duplex UE 408 is at a different frequency than the frequency occupied by the downlink transmission from the full-duplex gNB 402 to the half-duplex UE 406. Figure 4B and Figure 4C For a first full-duplex UE 412, interference may be mitigated if self-interference 416 from the first full-duplex UE 412, interference from a neighboring gNB 404, and / or interference from a second full-duplex UE 408 are at a frequency different from a frequency occupied by downlink transmissions from the full-duplex gNB 402 to the half-duplex UE 406.

Figure 5A 5 shows a subset 523 of all NR operating bands 502 specified for TDD mode in duplex mode 508. The operating bands are exemplary and non-limiting.

[0100] Figure 5D is a diagram illustrating an example of a TDD FD modulation scheme 540 according to some aspects of the present disclosure. Figure 5D In the example shown, time is shown along the horizontal axis and frequency is shown along the vertical axis. Figure 5D As shown in the example diagram of , a full-duplex network can utilize sub-band FDD in the unpaired spectrum (e.g., Figure 6B 544 and downlink control channels 542, as well as multiple PUSCHs 546 and uplink control channels 548, are depicted as occupying the sub-bands identified as nz UL & DL. FD Single operating band nz UL&DL FD For uplink and downlink without separating the UL and DL information in time (e.g., they occupy the same time slot at the same time). The term "nz" refers to any of the NR operating bands 502 specified for TDD mode in the duplex mode 508. Figure 5A A subset 523 of all NR operating bands 502 designated for TDD mode in duplex mode 508 is shown in FIG. Figure 5D, a first guard band 550 and a second guard band 552 are depicted. The first guard band 550 and the second guard band 552 can be of the same bandwidth or of different bandwidths. One or both of the first guard band 550 and the second guard band 552 can be zero-bandwidth guard bands. The first guard band 550 and the second guard band 552 in the unpaired spectrum (individually or collectively) can be smaller than the guard band 520 in the paired spectrum.

[0101] Figure 6A and Figure 6B Various examples of TDD FD operations are shown. Figure 6A is a diagram illustrating two examples of inter-band full-duplex (IBFD) modulation 600 according to some aspects of the present disclosure. Figure 6A In the example shown, time is shown along the horizontal axis and frequency is shown along the vertical axis. A first example 602 of IBFD is depicted on the left, while a second example 604 is depicted on the right. In the first example 602, the UL time-frequency resources 606 completely overlap with a portion of the DL time-frequency resources 608. In the second example 604, the UL time-frequency resources 610 partially overlap with a portion of the DL time-frequency resources 612. Therefore, a device (e.g., a base station and / or a scheduled entity) that employs IBFD can transmit and receive on the same time and frequency resources. That is, the device can transmit and receive at the same frequency at the same time. UL and DL share the same time and frequency resources. The overlap in time-frequency resources can be complete (complete overlap), as in the first example 602, or partial, as in the second example 604.

In sub-band FDD 614, devices can transmit and receive simultaneously but on different frequency resources (e.g., within the same carrier bandwidth). In some examples, the different frequency resources can be in unpaired spectrum. Guard band 620 separates UL resources 616 from DL resources 618. In some scenarios, guard band 620 can be relatively narrow (e.g., a few RBs). Therefore, transmission in UL resources 616 may cause leakage in DL resources 618, and vice versa.

[0103] Figure 7A and Figure 7B It is shown that a wireless communication device (eg, base station, UE, etc.) can use multiple antenna panels to support full-duplex communication. Figure 7AFIG2 is a schematic diagram illustrating an antenna array 700 for a TRP atop a base station 702 according to aspects of the present disclosure. Antenna array 700 is divided into two panels (panel 1 704, panel 2 706) with a physical partition 708 therebetween. Each of the two panels can be an antenna subarray. A given panel can transmit and / or receive a beam or beam group. A different number of panels can be used in other examples.

[0104] Other types of devices may include multi-panel antenna arrays for full-duplex communication. For example, a UE may have a first panel on one side of the UE and a second panel on the opposite side of the UE. As another example, a UE may have four panels, one at each corner of the UE.

[0105] Figure 7B is to depict two panels ( Figure 7A FIG2 is a diagram of a transmit or receive configuration for a UE (e.g., panel 1 704 and panel 2 706, or two panels on a UE, etc.). According to some aspects of the present disclosure, transmit (TX) and receive (RX) configurations for two panels are depicted for various DL and UL channels that can be implemented in a device (e.g., a scheduling entity or a scheduled entity) implementing flexible TDD.

[0106] As described above, in some examples, flexible TDD may involve using two panels to operate in TDD mode (where two panels on the gNB and one or more panels on the UE are configured for DL ​​or UL) or SBFD mode (where one panel on each of the gNB and UE is configured for UL and the other panel on each of the gNB and UE is configured for DL), as described below with reference to Figure 7B described.

[0107] exist Figure 7B On the left, when the antenna array 700 communicates in only a single direction at a time, both panel 1 704 and panel 2 706 can be configured for unidirectional communication as an example of TDD mode illustrating DL transmissions. For example, both panels 704 and 706 can be configured to transmit DL control 710, DL data 712, and DL data 713 as an example of DL transmissions during TDD mode. Figure 7B In the middle, when the antenna array 700 is simultaneously transmitting a combination of DL data 715 and DL control 717 and receiving UL data (e.g., PUSCH 714) and UL control 718, panel 1 704 can be configured for DL ​​transmission (i.e., TX) and panel 2 706 can be configured for UL reception (i.e., RX). Figure 7BOn the right, when the antenna array 700 receives only UL data (e.g., PUSCH 720) and UL control 722, both panel 1 704 and panel 2 706 can be configured for UL reception. The antenna array 700 is therefore configurable for both TDD and full-duplex operation (e.g., flexible TDD). The physical separation 708 between panel 1 704 and panel 2 706 can provide improved isolation between the panels (e.g., greater than about 50 dB of improved isolation) when compared to two panels without the physical separation 708. The above discussion can also be applied to antenna arrays in another type of device (e.g., a UE, reversing the references to DL and UL).

[0108] Traditionally, a network can configure up to four BWPs for a UE's DL and up to four BWPs for its UL. The UE can then use one of these configured BWPs as the active BWP for communication. A BWP specifies a set of useful frequencies for the UE (e.g., the frequency range within the allocated frequency band that the UE monitors for DL ​​transmissions). Typically, BWPs are contiguous in frequency.

[0109] Conventionally, the amount of time required to switch from operating in one active BWP to activating another BWP and then operating in the newly activated BWP (BWP switching time) can be relatively long, as shown below in Table 1. In Table 1, Type 1 is for so-called fast switching, while Type 2 is for so-called slow switching.

[0110]

[0111] Table 1

[0112] The UE can be configured to switch from one BWP to another in different ways. In some scenarios, the base station can send a DCI including a BWP indicator that specifies the BWP to be used by the UE. In some scenarios (e.g., for DL ​​BWP), the UE can switch to the default BWP when a timer (e.g., Bwp-InactivityTimer: ServingCellConfig.bwp-InactivityTimer) expires. In some scenarios, the base station can send radio resource control (RRC) signaling that specifies the BWP to be used by the UE.

[0113] In some scenarios, the MAC entity at the UE can initiate BWP switching. For example, during a random access channel (RACH) procedure, if the current active BWP is not configured for RACH, the UE can switch to the default BWP to find the RACH configuration. For example, when initiating the RACH procedure, if the physical random access channel (PRACH) opportunity is not configured for the active UL BWP, the MAC layer can switch the active UL BWP to the initial uplink BWP. On the contrary, if the PRACH opportunity is configured for the active UL BWP, the UE will not need to switch the active UL BWP. For DL, in some examples, if the serving cell is a SpCell and if the bwp-id of the active DL BWP is different from the bwp-id of the active UL BWP, BWP switching can occur. SpCell refers to a primary cell (pCell) (e.g., PCell of an MCG) or a primary secondary cell (PSCell) (e.g., of an SCG).

[0114] The way in which BWP switching occurs may depend on the duplexing method used. In TDD, DL and UL BWP switching may occur simultaneously. In FDD, DL BWP and UL BWP may be switched independently of each other.

[0115] The frequency allocation for BWP can be specified by the frequency domain resource allocation (FDRA) signaled in the DCI. There are two standard types of FDRA: Type 0 and Type 1.

[0116] In Type 0 FDRA, frequency allocation is specified by a bitmap. In some examples, the size of the bitmap is 18 bits or 9 bits. This scheme allows for disjoint RB allocations. In some examples, the allocation is a multiple of RBs (e.g., RB Groups (RBGs)). In some examples, one bit in the bitmap can correspond to one RBG. The RBG size depends on the BWP size and the configuration type, as shown in Table 2. For example, the parameter rbg-Size [enumerated {configuration 1, configuration 2}] can specify the RGB size for different configurations.

[0118] Table 2

[0119] In Type 1 FDRA, the frequency allocation is specified by the start and length (e.g., the start and length indicator value (SLIV)). Therefore, FDRA Type 1 is a contiguous RB allocation. In some examples, the frequency allocation is determined by the resource block start (RB_start) and the number of contiguous RBs combined in the resource indicator value (RIV) field. Equation 1 shows an example formula for RIV.

[0123]

[0124] In some aspects, the present disclosure relates to configuring multiple active BWPs for a UE and communication operations related thereto. Because of the slot format in full-duplex and because of the repeated switching between HD and FD slots, it may be advantageous for a UE to use at least two active BWPs in the DL and / or at least two active BWPs in the UL. For example, having at least two active BWPs can reduce (e.g., minimize) BWP switching time and provide greater flexibility for FD operation. A full-duplex UE can be configured with two (or possibly more) active BWPs in the DL and / or two (or possibly more) active BWPs in the UL. In the event that both BWPs are active simultaneously, the network can schedule DL and / or UL on both active BWPs simultaneously.

[0125] When an FD UE is configured with two active BWPs, one of the two active BWPs may be designated as the primary active BWP, while the other active BWP may be designated as the secondary active BWP. Figure 8 As shown, for the allocated bandwidth 802 in which a first BWP 804, a second BWP 806, a third BWP 808, and a fourth BWP 810 are defined, the first BWP 804 may be designated as a primary active BWP and the third BWP 808 may be designated as a secondary active BWP.

[0126] The present disclosure relates in some aspects to cross-BWP scheduling. Here, a UE may be configured to monitor PDCCH in one active BWP and operate in one or more active BWPs (eg, receive PDSCH in one or two active BWPs based on the scheduling carried by the PDCCH).

[0127] like Figure 9 As shown in cross-BWP scheduling 900, a PDCCH 902 carried by a first active BWP 904 (e.g., a primary active BWP) may indicate that a PDSCH 906 is scheduled in the first active BWP 904 and / or a PDSCH 908 is scheduled in a second active BWP 910 (e.g., a secondary active BWP). In some aspects, this may save power when monitoring the PDCCH because the UE does not need to monitor two active BWPs. Advantageously, since the BWP switching time is essentially zero, such scheduling may not be subject to the time delay imposed by the BWP switching.

[0128] As a specific example, a PDCCH carrying DCI1_0 or DCI1_1 can schedule PDSCH transmission on two active BWPs. In different scenarios, the BWP indication in the DCI can take different forms.

[0129] In some examples, the DCI indicates that the UE will use the primary active BWP. In this case, the UE can determine the cross-BWP allocation based on the FDRA.

[0130] For example, for type 0 FDRA, a bitmap of the form [1 1 0 0] may indicate that PDSCH is scheduled in a single active BWP. Conversely, a bitmap of the form [1 1 0 0 0 1 1 0] may indicate that PDSCH is scheduled in two active BWPs.

[0131] For Type 1 FDRA, an RB with Rbstart=1 and length=4 may indicate that the PDSCH is scheduled in a single active BWP. Conversely, an RB with Rbstart=1 and length=12 (where the bandwidth of the first active BWP is less than 12 RBs) may indicate that the PDSCH is scheduled in two active BWPs. In other words, if the frequency allocation in the FDRA is greater than the bandwidth of the primary active BWP, the UE may determine that the PDSCH is also in the secondary active BWP. Conversely, if the frequency allocation in the FDRA is less than or equal to the bandwidth of the primary active BWP, the UE may determine that the PDSCH is only in the primary active BWP.

[0132] In some examples, the DCI indicates that the UE will use a specific active BWP (e.g., a primary active BWP), and the DCI also includes an indication (e.g., a bit) specifying whether cross-BWP scheduling exists. For example, one value of the indication (e.g., zero) may mean that the scheduled PDSCH is included in the indicated active BWP. Conversely, another value of the indication (e.g., 1) may mean that the scheduled PDSCH spans two active BWPs.

[0133] In some aspects, the present disclosure relates to TDRA signaling for cross-BWP scheduling. In some examples, the same TDRA is used for PDSCH in both active BWPs. In some examples, different TDRAs may be used for PDSCH in both active BWPs. The base station may configure the UE to expect one or the other of these options. Additionally, UE capability information may indicate whether the UE supports one or both of these options. For the case where different TDRAs are used for different active BWPs, several different approaches may be used.

[0134] In some examples, the base station sends two independent TDRAs to the UE to apply to different active BWPs. For example, the DCI may include a first TDRA for a first active BWP and a second TDRA for a second active BWP.

[0135] In some examples, the base station sends a TDRA and an index offset for the first active BWP to the UE. The UE uses the index offset to derive the TDRA for the second active BWP. In some examples, the index offset is an offset from the TDRA index of the signaled TDRA. Thus, the UE can add the index offset to the TDRA index to determine the TDRA index for the TDRA of the second active BWP. The index offset can be signaled via DCI, via RRC signaling, or via some other type of signaling.

[0136] In some examples, the base station sends a TDRA and a time offset for the first active BWP to the UE. The UE uses the time offset to derive the TDRA for the second active BWP. In some examples, the time offset indicates the number of symbols. Thus, the UE can add the time offset to the symbol position of the signaled TDRA to determine the symbol position of the TDRA for the second active BWP. The time offset can be signaled via DCI, via RRC signaling, or via some other type of signaling.

[0137] In some aspects, the present disclosure relates to FDRA signaling for cross-BWP scheduling. In some examples, the same FDRA is used for PDSCH in two active BWPs. In some examples, different FDRAs may be used for PDSCH in two active BWPs. For example, the base station may indicate a different bitmap (Type 0 FDRA) or SLIV (Type 1 FDRA) for each active BWP. The base station may configure the UE to expect one or the other of these options. In addition, UE capability information (e.g., sent by the UE) may indicate whether the UE supports one or both of these options.

[0138] In some examples, the same Type-0 FDRA is assigned to both active BWPs. In some examples, the RBG size can depend on the active BWP bandwidth. Thus, a different RBG size can be assigned to each active BWP. Furthermore, in some examples, the bitmap size can be 18 for one active BWP and 9 for another active BWP.

[0139] For this type 0 FDRA scenario, the UE is signaled with a bitmap of the FDRA that covers the active BWP. Because the active BWP may have different bandwidths, the active BWP may have different RBG sizes.

[0140] Under this assumption, in some examples, if 9 bits are assigned to each active BWP, the UE will receive a total of 18 bits. This can be supported by legacy UEs. On the other hand, if 18 bits are assigned to an active BWP, the UE may receive 27 to 36 bits, which may be a relatively large overload.

[0141] In some examples, the UE adds the bandwidth of each active BWP to determine the RBG size. Thus, whether the total number of bits is 9 or 18, the UE can calculate the total number of bits required to signal the FDRA.

[0142] In some examples, the same Type 1 FDRA is specified for both active BWPs. In this case, the base station can signal a Type 1 FDRA (e.g., SLIV). In this case, the UE can assume that there is a combined active BWP (e.g., by combining the active BWPs), where the SLIV indicates the start and length of the combined BWP. The UE can then discard any frequency allocations that are not in either active BWP.

[0143] refer to Figure 10 In the cross-BWP scheduling 1000, a PDCCH 1002 carried by a first active BWP 1004 (e.g., a primary active BWP) may indicate that a PDSCH 1006 is scheduled in the first active BWP 1004 and / or a PDSCH 1008 is scheduled in a second active BWP 1010 (e.g., a secondary active BWP). In this example, the combined BWP may span an allocation for PDSCH 1008 and an allocation for PDSCH 1006, with the UE dropping the frequency band between the two allocations.

[0144] If the starting plus length (e.g. SLIV) exceeds the limit of the higher frequency active BWP, the UE may apply cyclic allocation in the lower frequency active BWP. Figure 9 In the example shown, the first active BWP 904 is in a higher frequency band than the second active BWP 910. Assuming that the SLIV starts at the bottom of the PDSCH 906, the length calculation can start from there and continue upward until it reaches the upper boundary of the first active BWP 904, then wrap around to the lower boundary of the second active BWP 910 and all the way to the PDSCH 908.

[0145] Figure 11 An example of signaling 1100 in a wireless communication network including a BS 1102 and a UE 1104 is shown. In some examples, the UE 1104 may correspond to Figure 1 、 Figure 2 、 Figure 4B 、 Figure 4C 、 Figure 7A 、 Figure 7B and Figure 12 In some examples, BS 1102 may correspond to any one or more of the UEs or scheduled entities shown in FIG. Figure 1 、 Figure 2 、 Figure 4B 、 Figure 4C 、 Figure 7A 、 Figure 7B and Figure 14 Any one or more BSs or scheduling entities shown in .

[0146] exist Figure 11 At 1106, BS 1102 sends an indication of cross-BWP scheduling to UE 1104. For example, BS 1102 may send DCI via the PDCCH in the first active BWP (e.g., the primary active BWP). The DCI may indicate that the PDSCH is scheduled in the second active BWP (e.g., the secondary active BWP). The DCI may indicate that the PDSCH is scheduled in the first active BWP.

[0147] At 1108, UE 1104 identifies an active BWP to use for communication operations (e.g., monitoring). In some examples, UE 1104 may monitor the PDCCH in a primary active BWP (e.g., a designated primary active BWP or an active BWP with the lowest ID). Thus, at 1106, UE 1104 may receive the DCI sent by BS 1102.

[0148] At 1108, UE 1104 identifies an active BWP allocation for communications scheduled by the DCI. In some examples, the DCI may indicate whether the scheduling is cross-BWP scheduling. In some examples, the DCI may indicate at least one TDRA for the scheduled active BWP. In some examples, the DCI may indicate at least one FDRA for the scheduled active BWP.

[0149] At 1112, UE 1104 and BS 1102 may communicate via one or more active BWPs indicated by the DCI.

[0150] Figure 12 1 is a block diagram illustrating an example of a hardware implementation of a UE 1200 employing a processing system 1214. For example, the UE 1200 may be a user equipment (UE) or other device configured to wirelessly communicate with a base station, such as in Figures 1-11 In some implementations, the UE 1200 may correspond to Figure 1 、 Figure 2 、 Figure 4B 、 Figure 4C 、 Figure 7A 、 Figure 7B and Figure 11 Any UE or scheduled entity shown in any one or more of .

[0151] According to various aspects of the present disclosure, the processing system 1214 can be utilized to implement any element or any portion of an element or any combination of elements. The processing system 1214 may include one or more processors 1204. Examples of the processor 1204 include a microprocessor, a microcontroller, a digital signal processor (DSP), a field programmable gate array (FPGA), a programmable logic device (PLD), a state machine, a gated logic, a discrete hardware circuit, and other suitable hardware configured to perform the various functions described throughout the present disclosure. In various examples, the UE 1200 can be configured to perform any one or more functions described herein. That is, the processor 1204 utilized in the UE 1200 can be used to implement any one or more processes and steps described herein.

[0152] In some cases, the processor 1204 may be implemented via a baseband or modem chip, and in other implementations, the processor 1204 itself may include multiple devices distinct from the baseband or modem chip (e.g., where they can work together to implement the examples described herein). As described above, various hardware arrangements and components other than the baseband modem processor may be used in various implementations, including RF chains, power amplifiers, modulators, buffers, interleavers, adders / summers, etc.

[0153] In this example, the processing system 1214 can be implemented using a bus architecture, generally represented by bus 1202. Depending on the specific application of the processing system 1214 and the overall design constraints, the bus 1202 can include any number of interconnecting buses and bridges. The bus 1202 communicatively couples various circuits together, including one or more processors (generally represented by processor 1204), memory 1205, and computer-readable media (generally represented by computer-readable media 1206). The bus 1202 can also link various other circuits, such as timing sources, peripherals, voltage regulators, and power management circuits, which are well known in the art and are not described further. The bus interface 1208 provides an interface between the bus 1202 and the transceiver 1210 and antenna array 1220, as well as an interface between the bus 1202 and the interface 1230. The transceiver 1210 provides a communication interface or component for communicating with various other devices via a wireless transmission medium. The interface 1230 provides a communication interface or component for communicating with various other devices and equipment (e.g., other devices housed within the same device as the UE or other external devices) via an internal bus or an external transmission medium (such as an Ethernet cable). Depending on the nature of the device, the interface 1230 may include a user interface (e.g., a keyboard, display, speaker, microphone, joystick). Of course, such a user interface is optional and may be omitted in some examples (such as IoT devices).

[0154] Processor 1204 is responsible for managing bus 1202 and general processing, including the execution of software stored on computer-readable media 1206. When executed by processor 1204, this software causes processing system 1214 to perform the various functions described below for any particular device. Computer-readable media 1206 and memory 1205 may also be used to store data manipulated by processor 1204 when executing the software. For example, memory 1205 may store BWP information 1215 used by processor 1204 to perform communication operations as described herein.

[0155] One or more processors 1204 in the processing system can execute software. Software should be construed broadly to mean instructions, instruction sets, code, code segments, program code, programs, subroutines, software modules, applications, software applications, software packages, routines, subroutines, objects, executable programs, execution threads, procedures, functions, etc., whether referred to as software, firmware, middleware, microcode, hardware description language, or otherwise. The software may reside on a computer-readable medium 1206.

[0156] Computer-readable medium 1206 may be a non-transitory computer-readable medium. As examples, non-transitory computer-readable media include magnetic storage devices (e.g., hard disks, floppy disks, magnetic strips), optical disks (e.g., compact disks (CDs) or digital versatile disks (DVDs)), smart cards, flash memory devices (e.g., cards, sticks, or key drives), random access memory (RAM), read-only memory (ROM), programmable ROM (PROM), erasable PROM (EPROM), electrically erasable PROM (EEPROM), registers, removable disks, and any other suitable medium for storing software and / or instructions that can be accessed and read by a computer. Computer-readable medium 1206 may reside in processing system 1214, external to processing system 1214, or distributed across multiple entities including processing system 1214. Computer-readable medium 1206 may be embodied in a computer program product. For example, a computer program product may include a computer-readable medium in packaging material. Those skilled in the art will recognize how best to implement the described functionality presented throughout this disclosure depending on the specific application and the overall design constraints imposed on the entire system.

[0157] UE 1200 may be configured to perform any one or more of the operations described herein (e.g., as described above in conjunction with Figures 1-11 As described below, Figure 13 In some aspects of the present disclosure, the processor 1204 utilized in the UE 1200 may include circuits configured for various functions.

[0158] Processor 1204 may include communication and processing circuitry 1241. Communication and processing circuitry 1241 may be configured to communicate with a base station, such as a gNB. Communication and processing circuitry 1241 may include one or more hardware components that provide a physical structure for performing various processes associated with wireless communication (e.g., signal reception and / or signal transmission) as described herein. Communication and processing circuitry 1241 may also include one or more hardware components that provide a physical structure for performing various processes associated with signal processing (e.g., processing received signals and / or processing signals to be transmitted) as described herein. In some examples, communication and processing circuitry 1241 may include two or more transmit / receive chains, each configured to process signals of a different RAT (or RAN) type. Communication and processing circuitry 1241 may also be configured to execute communication and processing software 1251 contained on computer-readable medium 1206 to implement one or more functions described herein.

[0159] In some examples, the communication and processing circuitry 1241 may be configured to receive and process downlink beamforming signals at millimeter wave frequencies or sub-6 GHz frequencies via the transceiver 1210 and the antenna array 1220. For example, the communication and processing circuitry 1241 may be configured to receive a corresponding reference signal (e.g., SSB or CSI-RS) from a base station on each of a plurality of downlink beams during downlink beam scanning via at least one first antenna panel of the antenna array 1220. The communication and processing circuitry 1241 may also be configured to send a beam measurement report to the base station.

[0160] In some examples, the communication and processing circuitry 1241 may also be configured to generate and transmit uplink beamforming signals at millimeter wave frequencies or sub-6 GHz frequencies via the transceiver 1210 and the antenna array 1220. For example, the communication and processing circuitry 1241 may be configured to transmit a corresponding reference signal (e.g., an SRS or DMRS) to the base station on each of a plurality of uplink beams during uplink beam scanning via at least one second antenna panel of the antenna array 1220.

[0161] The communication and processing circuit 1241 may also be configured to generate a request and send it to the base station. For example, the request may be included in a MAC-CE carried in a PUSCH, a PUCCH or UCI in a PUSCH, a random access message, or an RRC message. The communication and processing circuit 1241 may also be configured to generate a scheduling request and send it to the base station (e.g., via UCI in a PUCCH) to receive an uplink grant for the PUSCH carrying the MAC-CE including the request.

[0162] The communication and processing circuit 1241 may also be configured to generate an uplink signal and transmit the uplink signal on one or more uplink transmit beams applied to the uplink signal. The uplink signal may include, for example, PUCCH, PUSCH, SRS, DMRS, or PRACH.

[0163] The communication and processing circuitry 1241 may also be configured to control the antenna array 1220 and the transceiver 1210 to search for and identify multiple downlink transmit beams during downlink beam scanning. The communication and processing circuitry 1241 may also be configured to, for each identified downlink transmit beam, obtain multiple beam measurements on each of the multiple downlink receive beams via the antenna array 1220. The communication and processing circuitry 1241 may also be configured to generate a beam measurement report for transmission to the base station using the communication and processing circuitry 1241.

[0164] The communication and processing circuitry 1241 may also be configured to identify one or more selected uplink beams based on beam measurements obtained from the downlink beam reference signal. In some examples, the communication and processing circuitry 1241 may be configured to compare, for each of the serving downlink transmit beams, the corresponding RSRP (or other beam measurement) measured on each of the downlink receive beams to identify the serving downlink receive beam and further utilize the serving downlink receive beam as the selected uplink transmit beam. For one of the downlink transmit beams, each serving downlink receive beam may have the highest measured RSRP (or other beam measurement).

[0165] The communication and processing circuitry 1241 may be configured to generate one or more uplink transmit beams for transmission in an uplink beam sweep. Each uplink transmit beam may carry an uplink reference signal (e.g., an SRS) for base station measurements. The communication and processing circuitry 1241 may also be configured to identify a selected uplink transmit beam selected by the base station based on the uplink beam measurements. For example, the communication and processing circuitry 1241 may be configured to receive an indication of the selected uplink transmit beam from the base station.

[0166] In yet other aspects, it should be noted that the antenna array 1230 can be configured by the processor 1204 (and the memory 1205 or the computer-readable medium 1206) to implement a first antenna panel and a second antenna panel. Furthermore, the processor 1204 (and the memory 1205 or the computer-readable medium 1206) can be configured to use the first antenna panel to transmit a first beam (e.g., a UL transmit beam for FD communication) and to use the second antenna panel to receive a second beam (e.g., a DL receive beam for FD communication). The processor 1204 can use the second antenna panel to measure the UE's self-interference with the FD communication.

[0167] In some implementations where the communication involves receiving information, the communication and processing circuitry 1241 may obtain information from a component of the UE 1200 (e.g., from the transceiver 1210 that receives information via radio frequency signaling or some other type of signaling appropriate to the applicable communication medium), process (e.g., decode) the information, and output the processed information. For example, the communication and processing circuitry 1241 may output the information to another component of the processor 1204, the memory 1205, or the bus interface 1208. In some examples, the communication and processing circuitry 1241 may receive one or more of a signal, a message, other information, or any combination thereof. In some examples, the communication and processing circuitry 1241 may receive the information via one or more channels.

In some examples, the wireless communication method 1300 may be composed of Figure 12 In some examples, the wireless communication method 1300 can be performed by any suitable device or component for performing the functions or algorithms described below.

[0176] At block 1302, a UE may receive bandwidth part (BWP) configuration information from a base station, the BWP configuration information specifying a first active BWP for the UE and a second active BWP for the UE. Figure 12 The BWP configuration circuitry 1242 and the communication and processing circuitry 1241 and transceiver 1210 shown and described may provide means for receiving bandwidth part (BWP) configuration information from a base station.

[0177] In some examples, the active BWP designated for the UE may also be designated for at least one other UE.In some examples, the BWP configuration information may designate at least one third active BWP for the UE.

[0178] At block 1304, the UE may receive downlink control information (DCI) from the base station, wherein the DCI indicates a resource of the first active BWP, the second active BWP, or at least one of the first active BWP and the second active BWP. Figure 12 The BWP management circuitry 1243 and the communication and processing circuitry 1241 and transceiver 1210 shown and described may provide means for receiving downlink control information (DCI) from a base station.

[0179] At block 1306, the UE may identify from the DCI at least one resource in the first active BWP, in the second active BWP, or in the first active BWP and the second active BWP. Figure 12 The BWP management circuitry 1243 shown and described may provide means for identifying at least one resource in a first active BWP, a second active BWP, or both the first active BWP and the second active BWP from a DCI.

[0180] In some examples, the DCI indicates that the first active BWP is the primary active BWP.In some examples, the UE may determine whether the at least one resource includes the first resource in the second active BWP.

[0181] In some examples, the DCI indicates a frequency domain resource allocation (FDRA).In some examples, determining whether the at least one resource includes a first resource in the second active BWP may include determining whether a first bandwidth specified by the FDRA is greater than a second bandwidth of the first active BWP.

[0182] In some examples, the DCI may also include a cross-BWP scheduling indication. In some examples, determining whether the at least one resource includes the first resource in the second active BWP is based on the indication. In some examples, the indication, when set to a first value, specifies that the first active BWP carries the scheduled physical downlink shared channel (PDSCH). The indication, when set to a second value, specifies that the first active BWP and the second active BWP jointly carry the scheduled PDSCH.

In some examples, the first bit set is 9 bits and the second bit set is 9 bits, the first bit set is 9 bits and the second bit set is 18 bits, or the first bit set is 18 bits and the second bit set is 18 bits. In some examples, the UE may determine a resource block group (RBG) size based on the sum of the first bandwidth of the first active BWP and the second bandwidth of the second active BWP, and calculate the number of bits in the bitmap based on the RBG size. In some examples, determining the RBG size is also based on a configuration option for the FDRA. In some examples, the method may also include selecting the configuration option based on the configuration of the primary active BWP.

[0188] In some examples, the DCI indicates a frequency domain resource allocation (FDRA) for a first active BWP and a second active BWP, and the FDRA is specified by a start and length indicator value (SLIV). In some examples, the SLIV indicates the start of the frequency allocation including the first active BWP and the second active BWP, and the length of the frequency allocation including the first active BWP and the second active BWP. In some examples, the UE may determine that the start plus length exceeds a boundary of the first active BWP, where the first active BWP is in a higher frequency band than the second active BWP, and apply a cyclic allocation in the second active BWP after determining that the start plus length exceeds the boundary of the first active BWP.

[0189] At block 1308, the UE may receive information from the base station via at least one resource. Figure 12 The BWP management circuitry 1243 and the communication and processing circuitry 1241 and transceiver 1210 shown and described may provide means for receiving information from a base station via at least one resource.

[0190] In some examples, the UE may receive the PDSCH via resources in a first active BWP. In some examples, the UE may receive the PDSCH via resources in a second active BWP. In some examples, the UE may receive the PDSCH via first resources in the first active BWP and second resources in the second active BWP.
