Indicates cross-carrier bundling

Abstract

Various aspects relate to indicating cross-carrier (e.g., cross-cell) bundling. In some aspects, bundling may involve delivering information delivered on multiple carriers (e.g., information delivered from multiple cells or information delivered to multiple cells), where the information delivered on the carriers is combinable at the receiver. For example, a communications device may deliver the same set of information (e.g., transport blocks with the same content) via multiple carriers, deliver different redundant versions of a set of information via different carriers, deliver information via different beams on different carriers, or use a combination of these techniques to deliver information. The present disclosure relates in some aspects to indicating whether bundling is applied across carriers. For example, downlink control information (DCI) that schedules transmissions on multiple carriers (e.g., multiple component carriers) may include an indication of whether bundling is applied across all scheduled carriers or across a subset of scheduled carriers.

[0002] The next generation wireless communication system (e.g., 5GS) may include a 5G core network and a 5G radio access network (RAN), such as a new radio (NR)-RAN.

[0027] Various aspects of the present disclosure relate to indicating cross-carrier (e.g., cross-cell) bundling. In some aspects, bundling may involve delivering information on multiple carriers (e.g., information delivered from multiple cells or information delivered to multiple cells), wherein the information delivered on the carriers is combinable at the receiver. For example, a communication device may deliver the same set of information (e.g., transport blocks with the same content) via multiple carriers, deliver different redundant versions of a set of information via different carriers, deliver information via different beams on different carriers, or use a combination of these techniques to deliver information. In some aspects, the present disclosure relates to indicating whether bundling is applied across carriers (e.g., across cells). For example, a single instance of downlink control information (e.g., downlink control information delivered via a single timeslot) that schedules transmissions on multiple carriers (e.g., multiple component carriers) may include an indication of whether bundling is applied across all scheduled carriers or a subset of scheduled carriers. A single instance of downlink control information may be referred to herein as a DCI or the DCI.

[0028] The detailed description set forth below in conjunction with the accompanying drawings is intended as a description of various configurations and is not intended to represent the 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 addition, alternative configurations may be designed without departing from the scope of the present disclosure. In addition, well-known elements will not be described in detail or will be omitted to avoid obfuscation of the relevant details of the present disclosure.

[0029] Although aspects and embodiments 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 may occur in many different arrangements and scenarios. The innovations described herein may be implemented across many different platform types, devices, systems, shapes, sizes, and packaging arrangements. For example, embodiments and / or uses may be implemented via integrated chip embodiments and other devices based on non-module components (e.g., end-user devices, vehicles, communication devices, computing devices, industrial equipment, retail / purchase equipment, medical devices, AI-enabled devices, etc.). Although some examples may or may not be specific to use cases or applications, a variety of applicability of the described innovations may occur. The scope of implementations may range from chip-level or modular components to non-modular, non-chip-level implementations, and further to aggregated, distributed, or OEM devices or systems incorporating one or more aspects of the described innovations. In some practical settings, devices incorporating the described aspects and features may also have to include additional components and features for implementing and practicing the claimed and described embodiments. For example, the transmission and reception of wireless signals must include multiple components for analog and digital purposes (e.g., hardware components including antennas, 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.

[0030] The various concepts presented throughout this disclosure may be implemented across a variety of telecommunication systems, network architectures and communication standards. Figure 1 , various aspects of the present disclosure are described with reference to a wireless communication system 100 as a non-limiting illustrative example. 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. The RAN 104 includes a plurality of base stations 108. By means of the wireless communication system 100, the UE 106 can achieve data communication with an external data network 110 such as (but not limited to) the Internet.

[0031] According to various aspects of the present disclosure, the RAN 104 (e.g., the base station 108) may be configured to bundle information across carriers 122 and indicate (e.g., in a DCI) whether bundling is applied across two or more carriers scheduled by the DCI. The base station 108 may also be configured to perform operations related to bundling. For example, depending on how the DCI configures bundling, the base station 108 may deliver information to and / or receive information from the UE 106 on one or more component carriers. In addition, the UE 106 may be configured to bundle information across carriers 124 and receive (e.g., via the DCI) an indication of whether bundling is applied across two or more carriers (e.g., scheduled by the DCI) and for performing operations related to bundling. For example, depending on how bundling is configured, the UE 106 may deliver or receive information on one or more component carriers. These and other aspects of indicating cross-carrier bundling will be described in more detail following the following description of the wireless communication system 100.

[0032] The RAN 104 may implement any suitable radio access technology (RAT) to provide wireless 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) specification (commonly referred to as 5G). As another example, the RAN 104 may operate under a mix of 5GNR and Evolved Universal Terrestrial Radio Access Network (eUTRAN) standards (commonly referred to as 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 LTE and 5G NR standards. Of course, many other examples may be utilized within the scope of the present disclosure.

[0033] The actual telecommunication standard, network architecture, and / or communication standard used will depend on the specific application and the overall design constraints imposed on the system. For illustrative purposes, various aspects in the context of 5G and / or LTE systems may be described below. However, it should be understood that the teachings herein may also be used for other systems. Therefore, references to functionality in the context of 5G and / or LTE terminology should be understood to be equally applicable to other types of technologies, networks, components, signaling, etc.

[0034] As described above, the RAN 104 includes multiple base stations 108. In broad terms, a base station is a network element in a radio access network that is responsible for transmitting to or receiving from the radio of a UE in one or more cells. In different technologies, standards, or scenarios, those skilled in the art may refer to a base station as a transmit-receive point (TRP), 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), or some other suitable terminology. In an example in which the RAN 104 operates according to LTE and 5G NR standards, one of the base stations 108 may be an LTE base station and the other may be a 5G NR base station. Therefore, the functionality of the base station discussed in this article can be similar to (or incorporated into) a CIoT base station (C-BS), a NodeB, an evolved NodeB (eNodeB), a radio access network (RAN) access node, a radio network controller (RNC), a base station (BS), a radio base station (RBS), a base station controller (BSC), a base transceiver station (BTS), a transceiver function (TF), a radio transceiver, a radio router, a basic service set (BSS), an extended service set (ESS), a macro cell, a macro node, a home eNB (HeNB), a micro cell, a micro node, a micro node, or some other suitable entity.

[0035] In some aspects, a base station may refer to a physical entity that incorporates the radio head functionality of a particular physical cell. In some aspects, a base station may include 5G New Radio (NR) functionality with an orthogonal frequency division multiplexing (OFDM) based air interface. NR may support, for example but not limited to, enhanced mobile broadband (eMBB), mission critical services, and large-scale deployment of IoT devices.

[0036] The radio access network 104 is further illustrated as supporting wireless communications for multiple mobile devices. In the 3GPP standard, a mobile device may be referred to as a user device (UE) 106, but may also be referred to 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 handset, a terminal, a user agent, a mobile client, a client, or some other suitable terminology by a person skilled in the art. UE 106 may be a device that provides access to network services to a user. In an example in which RAN 104 operates according to LTE and 5G NR standards, UE 106 may be an evolved universal terrestrial radio access network-new radio dual connectivity (EN-DC) UE that is capable of simultaneously connecting to an LTE base station and an NR base station to receive data packets from the LTE base station and the NR base station.

[0037] In this document, a "mobile" device does not necessarily need to have the ability to move, and can be stationary. The term mobile device or mobile device refers to a variety of devices and technologies. A UE may include multiple hardware structural components whose size, shape, and arrangement facilitate communication; these components can include antennas, antenna arrays, RF chains, amplifiers, one or more processors, etc. that are electrically coupled to each other. For example, some non-limiting examples of mobile devices include mobile phones, cellular (cellular) phones, smart phones, session initiation protocol (SIP) phones, laptops, personal computers (PCs), notebooks, netbooks, smart books, tablets, personal digital assistants (PDAs), and various embedded systems, such as corresponding to the "Internet of Things" (IoT). A mobile device may be a cellular device, an Internet of Things (IoT) device, a cellular IoT (CIoT) device, an LTE wireless cellular device, a machine type communication (MTC) cellular device, a smart alarm, a remote sensor, a smart phone, a mobile phone, a smart meter, a personal digital assistant (PDA), a personal computer, a mesh node, a tablet computer, etc. The mobile device may also be a car or other vehicle, a remote sensor or actuator, a robot or robotic device, a satellite radio, a global positioning system (GPS) device, an object tracking device, a drone, a multicopter, a quadcopter, a remote control device, a consumer and / or wearable device such as glasses, a wearable camera, a virtual reality device, a smart watch, a health or fitness tracker, a digital audio player (e.g., an MP3 player), a camera, a game console, etc. The mobile device may also be a digital home or smart home device such as home audio, video, and / or multimedia devices, appliances, vending machines, smart lighting, home security systems, smart meters, etc. The mobile device may also be a smart energy device, a security device, a solar panel or solar array, a municipal infrastructure device that controls power (e.g., a smart grid), lighting, water, etc.; industrial automation and enterprise devices; logistics controllers; agricultural equipment; military defense equipment, vehicles, aircraft, ships, and weapons, etc. In addition, the mobile device may provide connected medical or telemedicine support, i.e., remote health care. 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 critical service data transport.

[0038] 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 an air interface can be referred to as downlink (DL) transmissions. According to certain aspects of the present disclosure, the term downlink can refer to point-to-multipoint transmissions initiated at a scheduling entity (further described below; e.g., base station 108). Another way to describe the 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. According to other aspects of the present disclosure, the term uplink can refer to point-to-point transmissions initiated at a scheduled entity (further described below; e.g., UE 106).

[0039] In some examples, access to the air interface may be scheduled, wherein a scheduling entity (e.g., a 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 may be responsible for scheduling, allocating, reconfiguring, and releasing resources for one or more scheduled entities. That is, for scheduled communications, a UE 106, which may be a scheduled entity, may utilize resources allocated by the scheduling entity 108.

[0040] Base station 108 is not the only entity that can act as a scheduling entity. That is, in some examples, a UE can act as a scheduling entity to schedule resources for one or more scheduled entities (e.g., one or more other UEs).

[0041] like Figure 1 As shown, the scheduling entity 108 can broadcast downlink traffic 112 to one or more scheduled entities 106. In a broad sense, the scheduling entity 108 is a node or device responsible for scheduling traffic in the wireless communication network, including downlink traffic 112 and, in some examples, uplink traffic 116 from one or more scheduled entities 106 to the scheduling entity 108. On the other hand, the scheduled entity 106 is a node or device that receives downlink control information 114, which includes but is not limited to scheduling information (e.g., grants), synchronization or timing information, or other control information from another entity in the wireless communication network (e.g., the scheduling entity 108).

[0042] In addition, uplink and / or downlink control information and / or traffic information can be divided into frames, subframes, time slots and / or symbols by time. As used herein, a symbol can refer to a time unit in which each subcarrier in an orthogonal frequency division multiplexing (OFDM) waveform carries a resource element (RE). A time slot can carry 7 or 14 OFDM symbols. A subframe can refer to a duration of 1 millisecond. Multiple subframes or time slots can be grouped together to form a single frame or radio frame. 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.

[0043] Typically, the base stations 108 may include a backhaul interface for communicating with a backhaul portion 120 of the wireless communication system. The backhaul 120 may provide a link between the base stations 108 and the core network 102. Additionally, in some examples, the backhaul network may provide interconnections between the respective base stations 108. Various types of backhaul interfaces may be used, such as a direct physical connection using any suitable transport network, a virtual network, etc.

[0044] The core network 102 may be part of the wireless communication system 100 and may be independent of the radio access technology used in the RAN 104. In some examples, the core network 102 may be configured according to a 5G standard (e.g., 5GC). In other examples, the core network 102 may be configured according to a 4G Evolved Packet Core (EPC) or any other suitable standard or configuration.

[0045] Reference now Figure 2 , a schematic diagram of RAN 200 is provided as an example and not a limitation. In some examples, RAN 200 may be similar to the ones described above and Figure 1 The geographic area covered by the RAN 200 may be divided into cellular regions (cells) that can be uniquely identified by a user equipment (UE) based on an identity broadcast from an access point or base station. Figure 2 The diagram shows macro cells 202, 204, and 206 and small cells 208, 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 can be identified by a single logical identifier belonging to the sector. In a cell divided into sectors, multiple sectors within a cell can be formed by antenna groups, each antenna being responsible for communicating with a UE in a portion of the cell.

[0046] exist Figure 2, two base stations 210 and 212 are shown in cells 202 and 204; and a third base station 214 is shown as controlling a remote radio head (RRH) 216 in cell 206. That is, the base station can have an integrated antenna, or can be connected to an antenna or RRH via a feeder cable. In the illustrated example, cells 202, 204, and 126 can be referred to as macro cells because base stations 210, 212, and 214 support cells with large sizes. In addition, a base station 218 is shown in a small cell 208 (e.g., a micro cell, a micro cell, a femto cell, a home base station, a home node B, a home e Node B, etc.), which can overlap with one or more macro cells. In this example, cell 208 can be referred to as a small cell because base station 218 supports a cell with a relatively small size. The cell size can be determined according to system design and component constraints.

[0047] It should be understood that the radio access network 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 described in detail in the accompanying drawings. Figure 1 The same as the base station / scheduling entity 108 shown in FIG.

[0048] Within the RAN 200, a cell 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 access to the core network 102 (see FIG. 1 ) for all UEs in the corresponding cell. Figure 1 ) access point. For example, UEs 222 and 224 may communicate with base station 210; UEs 226 and 228 may communicate with base station 212; UEs 230 and 232 may communicate with base station 214 via RRH 216; and UE 234 may communicate with base station 218. In some examples, UEs 222, 224, 226, 228, 230, 232, 234, 238, 240, and / or 242 may communicate with the base stations described above and in Figure 1 The UE / scheduled entity 106 shown in FIG.

[0049] In some examples, an unmanned aerial vehicle (UAV) 220, which may be a drone or a quadcopter, can be a mobile network node and can be configured to act as a UE. For example, UAV 220 can operate within cell 202 by communicating with base station 210.

[0050] In another aspect of RAN 200, bypass signals can be used between UEs without having to rely on scheduling or control information from a base station. For example, two or more UEs (e.g., UE 226 and 228) can use peer-to-peer (P2P) or bypass signals 227 to communicate with each other without relaying the communication through a base station (e.g., base station 212). In another example, UE 238 is shown communicating with UEs 240 and 242. Here, UE 238 can be used as a scheduling entity or a primary bypass device, and UEs 240 and 242 can be used as scheduled entities or non-primary (e.g., auxiliary) bypass devices. In yet another example, a UE can act as a scheduling entity in a device-to-device (D2D), peer-to-peer (P2P) or vehicle-to-vehicle (V2V) network and / or in a mesh network. In the mesh network example, in addition to communicating with the scheduling entity, UEs 240 and 242 can optionally communicate directly with each other. Thus, in a wireless communication system having scheduled access to time-frequency resources and having a cellular configuration, a P2P configuration, or a mesh configuration, a scheduling entity and one or more scheduled entities can communicate using the scheduled resources. In some examples, bypass signal 227 includes bypass traffic (e.g., a physical bypass shared channel) and bypass control (e.g., a physical bypass control channel).

[0051] In the radio access network 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 usually managed by an access and mobility management function (AMF, not shown). Figure 1 The security context management function (SCMF) of the core network 102 may include managing the security context of both the control plane and the user plane functions, and the security anchor function (SEAF) that performs authentication.

[0052] The radio access network 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 period, 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 handover or handover from the serving cell to the neighboring (target) cell. For example, a UE 224 (illustrated as a vehicle, although any suitable form of UE can be used) can move from a geographic area corresponding to its serving cell 202 to a geographic area corresponding to a neighboring cell 206. When the signal strength or quality from a neighboring cell 206 exceeds the signal strength or quality of its serving cell 202 for a given amount of time, the UE 224 can send a report message indicating this situation to its serving base station 210. In response, UE 224 may receive a handover command, and the UE may perform a handover to cell 206 .

[0053] 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)). UE222, 224, 226, 228, 230, and 232 can receive the unified synchronization signal, derive the 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 (e.g., base stations 210 and 214 / 216) within the radio access network 200. Each cell 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 of UE 224. As UE 224 moves through radio access network 200, the network may continue to monitor uplink pilot signals sent by UE 224. When the signal strength or quality of the pilot signal measured by a neighboring cell exceeds the signal strength or quality measured by a serving cell, network 200 may handover UE 224 from the serving cell to a neighboring cell, with or without notifying UE 224.

[0054] 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 with the same timing. The use of regions in a 5G network or other next generation communication network implements an uplink-based mobility framework and improves the efficiency of 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.

[0055] In various embodiments, the air interface in the radio access network 200 can utilize licensed spectrum, unlicensed spectrum, or shared spectrum. Licensed spectrum provides exclusive use of a portion of the spectrum, typically achieved by a mobile network operator purchasing a license from a government regulator. Unlicensed spectrum provides shared use of a portion of the spectrum without the need for a government-granted license. While some technical rules generally still need to be followed to access unlicensed spectrum, generally any operator or device can gain access. Shared spectrum can be between licensed and unlicensed spectrum, where technical rules or restrictions may be required to access the spectrum, but the spectrum can still be shared by multiple operators and / or multiple RATs. For example, a license holder of a portion of licensed spectrum may provide licensed shared access (LSA) to share the spectrum with other parties, for example, to obtain access under appropriate conditions determined by the license holder.

[0056] The air interface in the radio access network 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 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 spectrum-OFDM (DFT-s-OFDM) through 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 extension multiple access (RSMA), or other suitable multiple access schemes. In addition, multiplexed DL transmissions from base station 210 to UEs 222 and 224 may be provided 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.

[0057] The air interface in the radio access network 200 may further utilize one or more duplex algorithms. Duplex refers to a point-to-point communication link in which two endpoints can communicate with each other bidirectionally. Full-duplex means that two endpoints can communicate with each other at the same time. Half-duplex means that only one endpoint can send information to the other endpoint at a time. In a wireless link, a full-duplex channel generally relies on physical isolation of the transmitter and receiver and suitable interference cancellation techniques. Full-duplex emulation generally implements a wireless link by utilizing frequency division duplex (FDD) or time division duplex (TDD). In FDD, transmissions in different directions operate at different carrier frequencies. 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 transmissions in one direction, and at other times, the channel is dedicated to transmissions in the other direction, where the direction can change very quickly, such as several times per time slot.

[0058] Channel coding can be used for transmissions over the radio access network 200 to achieve a low block error rate (BLER) while still achieving very high data rates. That is, wireless communications can typically utilize suitable error-correcting block codes. In a typical block code, an information message or sequence is segmented into code blocks (CBs), and then an encoder (e.g., CODEC) at the transmitting device mathematically adds redundancy to the information message. Utilizing this redundancy in the encoded information message can improve the reliability of the message, enabling correction of any bit errors that may occur due to noise.

[0059] In early 5G NR specifications, traffic was encoded using quasi-cyclic low-density parity check (LDPC) with two different base maps: one base map for large code blocks and / or high code rates, and another base map for other cases. Control information and the physical broadcast channel (PBCH) are encoded using polar coding based on nested sequences. For these channels, puncturing, shortening, and repetition are used for rate matching.

[0060] 5G-NR networks may further support carrier aggregation of component carriers transmitted from different transmit and receive points (TRPs) in a multi-cell transmission environment. In some aspects, the term component carrier refers to a carrier frequency (or frequency band) used for intra-cell communication. Figure 3 An example of a multi-cell transmission environment 300 is shown. The multi-cell transmission environment 300 includes a primary serving cell (PCell) 302 and one or more secondary serving cells (SCells) 306a, 306b, 306c, and 306d. PCell 302 can be referred to as an anchor cell that provides a radio resource control (RRC) connection to a UE. In some examples, the PCell and SCell can be collocated (e.g., different TRPs are co-located).

[0061] When carrier aggregation is configured, one or more of the SCells 306a-306d may be activated or added to the PCell 302 to form a serving cell serving a user equipment (UE) 310. Each serving cell corresponds to a component carrier (CC). The CC of the PCell 302 may be referred to as a primary CC, and the CC of the SCells 306a-306d may be referred to as a secondary CC. The PCell 302 and one or more SCells 306 may be provided by corresponding base stations 304 and 308a-308c or similar. Figure 1 and Figure 2 The scheduling entity shown in . Figure 3 In the example shown, SCells 306a-306c are served by corresponding base stations 308a-308c, respectively. However, SCell 306d is collocated with PCell 302. For example, base station 304 may include multiple TRPs, each supporting a different carrier. The coverage of PCell 302 and SCell 306d may be different because component carriers in different frequency bands may experience different path losses.

[0062] The PCell 302 may add or remove one or more SCells 306a-306d to improve reliability and / or increase data rates for connections to the UE 310. However, the PCell 302 may only change when switching to another PCell.

[0063] In some examples, PCell 302 can utilize a first radio access technology (RAT), such as LTE, and one or more SCells 306 can utilize a second RAT, such as 5G-NR. In this example, the multi-cell transmission environment can be referred to as a multi-RAT dual connection (MR-DC) environment. In some examples, PCell 302 can be a low-band cell and SCell 306 can be a high-band cell. The low-band (LB) cell uses CCs in a frequency band lower than the high-band cell. For example, a high-band cell can use a millimeter wave CC, and a low-band cell can use a CC in a frequency band lower than the millimeter wave (e.g., a frequency band lower than 6 GHz). In general, a cell using a millimeter wave CC is able to provide a larger bandwidth than a cell using a low-band CC. In addition, when using a carrier with a frequency higher than 6 GHz (e.g., millimeter wave), beamforming can be used to send and receive signals.

[0064] The PCell 302 is responsible not only for connection establishment, but also for radio resource management (RRM) and radio link monitoring (RLM) of the connection with the UE 310. For example, the PCell 302 can activate one or more SCells (e.g., SCell 306a) for multi-cell communication with the UE 310. In some examples, when the SCell 306a is not used for data transmission / reception, the PCell can activate the SCell 306a as needed instead of keeping the SCell activated in order to reduce the power consumption of the UE 310. However, there is a delay in the process of activating the SCell 306a, which is mainly due to the time involved in the time / frequency synchronization between the UE 310 and the SCell 306a. For example, in order to synchronize the UE 310 with the SCell 306a, the UE 310 and / or the SCell 306a can measure or utilize one or more reference signals communicated between the UE 310 and the SCell 306a. Examples of reference signals may include, but are not limited to, aperiodic or semi-persistent downlink CSI-RS, downlink synchronization signal blocks (SSBs), and / or uplink SRS.

[0065] In some aspects, the present disclosure relates to a single DCI indicating a joint bundle across multiple carriers (e.g., across CCs or cells). This scheme can be used, for example, in NR dynamic spectrum sharing (DSS). In DSS, cross-carrier scheduling can involve, for example, a physical downlink control channel (PDCCH) of a secondary cell (SCell) or a primary cell (PCell) scheduling a physical downlink shared channel (PDSCH) or a physical uplink shared channel (PUSCH) on a PCell and / or SCell.

[0066] Figure 4 Two examples are shown in which a single DCI schedules multiple carriers. In the first example 400A, on the first component carrier ( Figure 4 In the second example 400B, DCI 408 schedules a first PUSCH 410 (designated as PUSCH 1) on the second CC (designated as CC 1) and schedules a second PUSCH 412 (designated as PUSCH 2) on the third CC (designated as CC 2).

[0067] In various aspects of the present disclosure, when a single DCI schedules transmissions on multiple CCs, the DCI may indicate whether bundling is applied across all scheduled CCs or across a subset of scheduled CCs. By indicating bundling in this manner, a device receiving the DCI can efficiently determine whether bundling is used, where to use bundling (e.g., on which CCs), and how to configure bundling.

[0068] In some aspects, the term "bundling" as used herein relates to sending first information as a copy of second information on different CCs (cells). For example, a transport block (TB) including the same information may be delivered on different CCs. In some aspects, the term "bundling" as used herein relates to communicating first information that may be combined with second information on different CCs (cells). For example, a first data set may be delivered on a first CC and a second data set may be delivered on a second CC. The data sets may be generated so that a device receiving the data sets can combine the two data sets to improve the quality of the received data. For example, a UE may combine data sets received from a gNB to improve a downlink (DL) signal-to-noise-and-interference ratio (SINR). As another example, a gNB may combine data sets received from a UE to improve an uplink (UL) SINR. In some aspects, the term "bundling" as used herein relates to communicating first information and second information via different beams on different CCs (cells). The beams may be configured so that a device receiving the first information via a first beam on one CC and the second information via a second beam on another CC can combine the two data sets to improve the quality of the received information.

[0069] Various types of first information and second information may be bundled on different CCs scheduled by a single DCI. In some aspects, the information to be bundled may include: a demodulated reference signal (DMRS), PDSCH traffic, PUSCH traffic, physical uplink control channel (PUCCH) control information, physical random access channel (PRACH) information, a sounding reference signal (SRS), or a channel state information reference signal (CSI-RS). In other examples, other information may be bundled.

[0070] In some aspects, different redundancy versions (RVs) may be used to provide combinable first information and second information delivered on different CCs. For example, a device may deliver first information and second information associated with one RV on one CC, and deliver first information and second information associated with different RVs on another CC. In this case, the DCI may indicate that different RVs are to be used on different CCs.

[0071] For example, RV can be used in a hybrid automatic repeat request (HARQ) scheme. HARQ is a technique in which the integrity of a packet transmission (e.g., a code block) can be checked on the receiving side to ensure accuracy, for example, using any suitable integrity check mechanism, such as a checksum or a cyclic redundancy check (CRC). If the integrity of the transmission is confirmed, an ACK can be sent, and if it is not confirmed, a NACK can be sent. In response to the NACK, the transmitting device can send a HARQ retransmission, which can achieve chase combining, incremental redundancy, etc. In chase combining HARQ (HARQ-CC), the retransmitted code block is the same as the original transmission of the code block. That is, if the code block is not correctly decoded at the receiving device, resulting in a NACK, the transmitting device can retransmit a complete code block including the same information as the original transmission. Then, with the help of a process called soft combining, the information can be obtained ideally without error, where the redundant bits from the retransmission can be combined before decoding to increase the probability of correct reception of each bit. On the other hand, in incremental redundancy HARQ (HARQ-IR), the retransmitted code blocks can be different from the code blocks of the original transmission, and furthermore, if multiple retransmissions are performed, each retransmission can be different from each other. Here, the retransmissions can include different groups of coded bits: for example, corresponding to different code rates or algorithms; corresponding to different parts of the original code blocks, some of which may not have been sent in the original transmission; corresponding to forward error correction (FEC) bits that were not sent in the original transmission; or other suitable schemes. As with HARQ-CC, here, information can be obtained without error by combining the retransmitted bits with the originally transmitted bits using soft combining.

[0072] NR uses low-density parity-check (LDPC) codes for the DL shared channel. LDPC codes utilize HARQ-IR to deliver different data redundancy versions (RVs) on each retransmission. For example, four redundancy versions may be sent in the following default order: redundancy version 0 (RV0), redundancy version 2 (RV2), redundancy version 3 (RV3), and redundancy version 1 (RV1). Each redundancy version may include systematic bits (e.g., bits carrying information to be sent) and / or parity bits (e.g., bits carrying redundant information generated from a combination of the original information). For LDPC codes, not all RVs contain the same number of systematic bits. For example, Figure 5As shown in the coding diagram 500, RV0 and RV3 contain a large number of systematic bits and are therefore self-decodable (e.g., these bits can be used to decode data without additional bits). In contrast, RV1 and RV2 do not contain a large number of systematic bits (e.g., they may mainly include parity bits) and are therefore not self-decodable (e.g., it is generally not possible to decode data using these bits alone). Other types of RVs may be used in other examples.

[0073] In some aspects, different beams may be used to provide combinable first information and second information delivered on different CCs. Beamforming techniques may be used to counteract or reduce the effects of attenuation and provide highly directional communication beams that more efficiently use wireless communication channels. Beamforming typically utilizes an antenna array configured for directional signal transmission or reception. In order to transmit a beam through beamforming, the phase and relative amplitude of the signal transmitted by each transmitter or antenna are controlled so that a pattern of constructive and destructive interference is generated in the wavefront. At the receiver, signals from different antennas or sensors are combined to recover the beamformed signal. In some examples, a device (e.g., a base station) may include two or more TRPs, each communicating on a different CC. The base station may use one beam to send the first information and the second information on one CC, and use a different beam to send the first information and the second information on another CC. In this case, the DCI may indicate different beams to be used on different CCs.

[0074] For scheduled UL signals, the DCI may instruct the UE to send bundled (e.g., combined by the gNB) UL signals on different CCs. In response, the UE may deliver the same content (e.g., TB) on different CCs. As another example, the UE may respond by delivering information associated with the same or different RVs on different CCs. As yet another example, the UE may deliver information via different beams on different CCs. The UE may also use a combination of these techniques (e.g., different RVs and different beams).

[0075] For scheduled DL signals, the DCI may indicate to the UE to receive bundled (e.g., UE-combinable) DL signals on different CCs. That is, the gNB may deliver the same content (e.g., TB) on different CCs, the gNB may deliver information associated with the same or different RVs on different CCs, the gNB may deliver information via different beams on different CCs, or the gNB may use a combination of these techniques (e.g., different RVs and different beams).

[0076] The DCI may indicate whether the UE is to deliver bundled UL feedback signals (e.g., ACK / NACK) on different CCs (e.g., feedback signals that may be combined by the gNB). If the DCI indicates a bundled feedback signal, the DCI may indicate the corresponding configuration, such as the beams used on the different CCs.

[0077] Figure 6 6 is a schematic diagram of a wireless communication system 600 that can be used to provide cross-carrier bundling as taught herein. The wireless communication system 600 includes a first wireless communication device 602 (e.g., a base station) and a second wireless communication device 604 (e.g., a UE), and possibly other devices (not shown). In some embodiments, the first device 602 can communicate with Figure 1 In some embodiments, the second device 604 may correspond to the BS 108 (e.g., gNB, transmission and reception point, etc.) of the wireless communication network. Figure 1 Corresponding to UE106.

[0078] The first device 602 includes a communication controller 606 for controlling communication with (e.g., sending to and / or receiving from) the second device 604 and / or other devices via a transceiver 608. The second device 604 includes a communication controller 610 for controlling communication with (e.g., sending to and / or receiving from) the first device 602 and / or other devices via a transceiver 612.

[0079] The communication controller 606 includes a DCI generator 614 for generating a DCI 616 indicating cross-carrier bundling as taught herein. For example, the DCI generator 614 may generate a DCI including one or more indications of which CCs are bundled, what content / signals are bundled, how bundling is performed (e.g., same content, different RV, different beams, etc.), and the like.

[0080] The communication controller 606 also includes a cross-carrier communication controller 618 for delivering or receiving content / signals as taught herein via multiple CCs 620. For example, for downlink communications, the cross-carrier communication controller 618 can generate content / signals that are bundled on the CCs 620. For uplink communications, the cross-carrier communication controller 618 can process (e.g., combine) the content / signals that are bundled on the CCs 620.

[0081] The communication controller 610 of the second device 604 includes a DCI processor 622 for receiving and analyzing the DCI 616. For example, the DCI processor 622 can parse the indication included in the DCI to determine: which CCs are bundled, what content / signals are bundled, how the bundling is performed (e.g., same content, different RV, different beams, etc.), etc.

[0082] The communication controller 610 also includes a cross-carrier communication controller 624 for delivering or receiving content / signals via the CC 620, as taught herein. For example, for uplink communications, the cross-carrier communication controller 624 can generate content / signals that are bundled on the CC 620. For downlink communications, the cross-carrier communication controller 618 can process (e.g., combine) the content / signals that are bundled on the CC 620.

[0083] Figure 7 An example of signaling for cross-carrier bundling between devices in a wireless communication system 700 is shown. The system 700 includes a UE 702, a first BS 704, and a second BS 706. In some implementations, the UE 702 may communicate with Figure 1 106. In this example, the first BS 704 provides two cells (C0 and CC1), while the second BS 706 provides one cell (CC2). In other examples, all cells (CC0, CC1, and CC3) may be provided by a single BS. In some embodiments, BS 704 or BS 706 may be provided by a single BS. Figure 1 Corresponding to BS 108 (e.g., gNB, transmit and receive point, etc.).

[0084] At step 708, first BS 704 delivers DCI on CC0. The DCI indicates that bundling exists on CC1 and CC2 in accordance with the teachings herein.

[0085] As a first example, the DCI may indicate that the PDSCH is bundled across CC1 and CC2. In this case, at step 710, the first BS 704 delivers PDSCH 1 to the UE 702 on CC1, and at step 712, the second BS 706 delivers PDSCH 2 to the UE 702 on CC2.

[0086] As a second example, the DCI may indicate that PUSCH is bundled across CC1 and CC2. In this case, at step 714, UE 702 delivers PUSCH 1 to first BS 704 on CC1, and at step 716, UE 702 delivers PUSCH 2 to second BS 706 on CC2.

[0087] As a third example, the DCI may indicate that PUCCH is bundled across CC1 and CC2. In this case, at step 718, UE 702 delivers PUCCH 1 to first BS 704 on CC1, and at step 720, UE 702 delivers PUCCH 2 to second BS 706 on CC2.

[0088] In other examples, other types of signaling may be used.

[0089] Figure 8 An example of a schedule 800 that may be specified by a DCI is illustrated. As discussed herein, in some examples, the DCI may be carried in a PDCCH.

[0090] In time slot 0, the PDCCH 802 of the first cell (CC 1) schedules the bundled PDSCH transmission in time slot 1. Specifically, the DCI ( Figure 8 (not shown) schedules a first PDSCH 804 (PDSCH 1) with RV0 on CC1, and schedules a second PDSCH 806 (PDSCH 2) with RV2 on CC2. PDSCH 1 and PDSCH 2 have the same transport block or data information to be delivered. Therefore, the gNB ( Figure 8 804 and 806). The UE (not shown) receiving the PDCCH 802, the first PDSCH 804, and the second PDSCH 806 may encode the PDSCH information to obtain an RV0 data set and an RV2 data set. The gNB may then deliver the RV0 data set on CC1 and the RV2 data set on CC2. Figure 8 804 is an RV0 data set and the second PDSCH 806 is an RV2 data set. Therefore, the UE will be able to decode the first PDSCH 804 and the second PDSCH 806 (e.g., a combined data set) to obtain downlink information.

[0091] In time slot 2, PDCCH 808 of the first cell (CC 1) schedules bundled PUSCH transmission in time slot 3. Specifically, the DCI ( Figure 8 (not shown) schedules a first PUSCH 810 (PUSCH 1) with RV0 on CC1, and schedules a second PUSCH 812 (PUSCH 2) with RV2 on CC2. PUSCH 1 and PUSCH 2 have the same transport block or data information to be delivered. Therefore, the UE ( Figure 8 The UE may then deliver the RV0 data set on CC1 and the RV2 data set on CC2. The gNB (not shown) that delivers the PDCCH 808 and receives the first PUSCH 810 and the second PUSCH 812 Figure 8 The gNB (not shown) can thereby determine that the first PUSCH 810 is an RV0 data set and the second PUSCH 812 is an RV2 data set. Therefore, the gNB will be able to decode the first PUSCH 810 and the second PUSCH 812 (e.g., a combined data set) to obtain uplink information.

[0092] In time slot 4, PDCCH 814 of the first cell (CC 1) schedules bundled PUCCH transmission in time slot 5. Specifically, the DCI ( Figure 8 816 (PUCCH 1) is scheduled on CC1, and the second PUCCH 818 (PUCCH 2) is scheduled on CC2. PUCCH 1 and PUCCH 2 have the same uplink control information to be transmitted. Therefore, UE ( Figure 8 The UE may then deliver the first PUCCH 816 on CC1 and the second PUCCH 818 on CC2. The gNB (not shown) that delivers the PDCCH 84 and receives the first PUCCH 816 and the second PUCCH 818 may then deliver the first PUCCH 816 and the second PUCCH 818 to the UE. Figure 8 ) can thereby combine the PUCCH information to obtain uplink control information.

[0093] The present disclosure relates in some aspects to RV mapping schemes. For example, a specific RV value can be mapped to a set of RV values ​​for different CCs (cells). In this way, the size (e.g., number of bits) of the RV indication in the DCI can be reduced compared to a scheme in which, for example, a separate RV indication exists for each carrier.

[0094] Table 1 shows an example of RV mapping according to the teachings of this document. Here, the RV in the DCI is two bits. RV value 0 in the DCI is mapped to RV0 for CC1 and RV2 for CC2. RV value 2 in the DCI is mapped to RV2 for CC1 and RV3 for CC2. RV value 2 in the DCI is mapped to RV2 for CC1 and RV3 for CC2. RV value 3 in the DCI is mapped to RV3 for CC1 and RV1 for CC2. RV value 1 in the DCI is mapped to RV1 for CC1 and RV0 for CC2. Other RV mappings can be used in other examples. As another example, the RV mapping can be configured by RRC signaling. For example, RRC can configure an offset for RV. The RV in the DCI indicates the RV value to be used in CC1, and the RV to be used in CC2 is derived based on the RV indicated in the DCI and the offset configured by RRC signaling.

[0096] Table 1

[0097] Fig. 9An example of a DMRS schedule 900 that may be specified by a DCI is illustrated. As discussed herein, in some examples, the DCI may be carried in a PDCCH.

[0098] In time slot 0, PDCCH 902 of the first cell (CC 1) schedules the bundled PDSCH transmission in time slot 1. Specifically, the DCI ( Fig. 9 1 (not shown) schedules a first PDSCH 904 (PDSCH 1) on CC1 and a second PDSCH 906 (PDSCH 2) on CC2. In addition, the DCI schedules a DMRS in slot 1, as shown by the narrow diagonal hatched columns (e.g., DMRS 908 on CC1 and DMRS 910 on CC2). In this case, the gNB ( Fig. 9 (not shown) can use the same DMRS port (or the same code division multiplexing (CDM) port group) and the same precoder to deliver DMRS on CC1 and CC2. Fig. 9 (not shown) can thereby effectively restore the first PDSCH 904 and the second PDSCH 906 based on the DMRS to obtain downlink information. For better channel estimation, the DMRS 908 on CC1 and the DMRS 910 on CC2 can be jointly estimated at the UE.

[0099] In time slot 2, PDCCH 912 of the first cell (CC 1) schedules bundled PUSCH transmission in time slot 3. Specifically, the DCI ( Fig. 9 1 (not shown) schedules a first PUSCH 914 (PUSCH 1) on CC1 and a second PUSCH 916 (PUSCH 2) on CC2. In addition, the DCI schedules DMRS in slot 3, as shown by the narrow diagonal hatched columns. In this case, the UE ( Fig. 9 (not shown) can use the same DMRS port (or the same code division multiplexing (CDM) port group) and the same precoder to deliver DMRS on CC1 and CC2. Fig. 9 (not shown) can effectively recover the first PUSCH 914 and the second PUSCH 916 based on DMRS to obtain uplink information. For better channel estimation, the DMRS on CC1 and the DMRS on CC2 can be jointly estimated at the gNB.

[0100] In time slot 4, PDCCH 918 of the first cell (CC 1) schedules bundled PUCCH transmission in time slot 5. Specifically, the DCI ( Fig. 91) schedules a first PUCCH 920 (PUCCH 1) on CC1 and a second PUCCH 922 (PUCCH 2) on CC2. In addition, the DCI schedules DMRS in slot 3, as shown by the narrow diagonal hatched columns. In this case, the UE ( Fig. 9 (not shown) can use the same precoder to deliver DMRS on CC1 and CC2. The gNB delivering PDCCH918 ( Fig. 9 (not shown) can thereby effectively restore the first PUCCH 920 and the second PUCCH 922 based on the DMRS to obtain uplink control information.
