Abstract
Description
Technical Field
[0001] This disclosure relates to communication devices, infrastructure devices, and methods for transmitting data by communication equipment in a wireless communication network.
[0002] This application claims priority under the Paris Convention to European patent application EP 20202427.9, the contents of which are incorporated herein by reference. Background Technology
[0003] The background description provided herein is intended to provide a general overview of the contents of this disclosure. Within the scope described in this background section, the work of the inventors and aspects of the description that may not conform to the prior art at the time of application are neither explicitly nor implicitly acknowledged as prior art opposing the present invention.
[0004] The latest generation of mobile telecommunications systems, such as those based on the 3GPP-defined UMTS and LTE architectures, are capable of supporting a wider range of services than the simple voice and messaging services offered by previous generations of mobile telecommunications systems. For example, leveraging the improved radio interfaces and enhanced data rates provided by LTE systems, users can enjoy high-data-rate applications such as mobile video streaming and mobile video conferencing, which were previously only available through fixed-line data connections. Therefore, the demand for deploying such networks is strong, and the coverage areas of these networks—i.e., the geographical locations where network access is available—are expected to continue to increase rapidly.
[0005] Future wireless communication networks will be expected to routinely and efficiently support an ever-expanding range of devices associated with a wider range of data traffic profiles and types than those optimized for by existing systems. For example, future wireless communication networks are expected to efficiently support communication with devices including reduced-complexity devices, machine-type communication (MTC) devices, high-resolution video displays, virtual reality headsets, and more. Some of these different types of devices can be deployed in very large numbers, such as low-complexity devices supporting the “Internet of Things”, and are typically associated with the transmission of relatively small amounts of data with relatively high latency tolerances. Other types of devices, such as those supporting high-definition video streaming, can be associated with the transmission of relatively large amounts of data with relatively low latency tolerances. Other types of devices, such as those used for autonomous vehicle communication and other critical applications, can be characterized by data that should be transmitted over the network with low latency and high reliability. Depending on the application they run, individual device types may also be associated with different traffic profiles / characteristics. For example, when a smartphone is running a video streaming application (high downlink data), different considerations can be applied to effectively support data exchange with the smartphone compared to when the smartphone is running an internet browsing application (sporadic uplink and downlink data) or used for voice communication by emergency responders in an emergency (where data is subject to strict reliability and latency requirements).
[0006] In view of this, it is anticipated that future wireless communication networks, such as those that may be referred to as 5G or New Radio (NR) systems / New Radio Access Technology (RAT) systems, as well as future iterations / releases of existing systems, will be able to effectively support connectivity for a wide range of devices associated with different applications and data traffic profiles and requirements.
[0007] An example of the new service is called Ultra Reliable Low Latency Communication (URLLC) service, which, as the name suggests, requires the transmission of data units or packets with high reliability and low communication latency. Another example of the new service is Enhanced Mobile Broadband (eMBB) service, which is characterized by high capacity and requires support for up to 20Gb / s. Therefore, URLLC and eMBB type services represent challenging examples for LTE-type communication systems and 5G / NR communication systems.
[0008] The increasing use of different types of network infrastructure equipment and terminal devices associated with different traffic profiles has brought new challenges to effectively handling communications in wireless communication systems. Summary of the Invention
[0009] This disclosure can help resolve or mitigate at least some of the problems discussed above.
[0010] Embodiments of this technology can provide a method for operating a communication device configured to transmit data to a wireless communication network via a radio access interface.

Here, each transmission version of one or more transmission versions of CG-UCI is repeated multiple times during the transmission of uplink data.
[0011] Some further embodiments of this technology can provide a method for operating a communication device configured to transmit data to a wireless communication network via a wireless access interface. One method includes operating according to a configured authorized CG operating mode, the CG operating mode including determining a sequence of instances of uplink communication resources of the wireless access interface, transmitting a signal to the wireless communication network in at least one instance of the sequence of instances of uplink communication resources of the wireless access interface, transmitting uplink data to the wireless communication network in two or more instances of the sequence of instances of uplink communication resources of the wireless access interface as multiple repetitions of the uplink data, and transmitting one or more versions of uplink control information CG-UCI to the wireless communication network, each version of CG-UCI associated with multiple instances of the sequence of instances of uplink communication resources of the wireless access interface. Here, one or more transmitted versions of CG-UCI are each transmitted as two or more separate portions, each of the two or more portions being transmitted in different instances of the two or more instances during the transmission of uplink data.
[0012] In addition to methods for operating communication equipment, embodiments of this technology also relate to methods for operating infrastructure equipment, communication equipment, and infrastructure equipment, as well as circuitry for communication equipment and infrastructure equipment, allowing for more efficient use of radio resources through communication equipment.

[0044] Long Term Evolution Advanced Wireless Access (4G)
[0045] Figure 1 A schematic diagram is provided illustrating some basic functions of a mobile telecommunications network / system 6 that typically operates according to LTE principles. However, the mobile telecommunications network / system 6 may also support other radio access technologies and may be adapted to implement the embodiments of this disclosure described herein. Figure 1 The various elements and certain aspects of their respective operating modes are well known and defined in the relevant standards managed by the 3GPP (RTM) organization, and described in many books on the subject, such as those by Holma H. and TosK. A la A[1]. It should be understood that operational aspects of telecommunications networks not specifically described herein (e.g., regarding specific communication protocols and physical channels for communication between different components) can be implemented according to any known technology, such as modifications and supplements to relevant standards and known recommendations.
[0046] Network 6 includes multiple base stations 1 connected to core network 2. Each base station provides coverage area 3 (i.e., a cell) within which data can be transmitted to and from communication equipment 4. Although each base station 1... Figure 1 While shown as a single entity, those skilled in the art will understand that some functions of a base station can be performed by different, interconnected components, such as antennas (or antenna heads), remote radio heads, amplifiers, etc. One or more base stations can collectively form a radio access network.
[0047] Data is transmitted from base station 1 to communication equipment 4 within its respective coverage area 3 via a radio downlink. Data is transmitted from communication equipment 4 to base station 1 via a radio uplink. Core network 2 routes data to and from communication equipment 4 via each base station 1, and provides functions such as authentication, mobility management, and billing. Terminal equipment may also be referred to as mobile station, user equipment (UE), user terminal, mobile radio, communication equipment, etc. Services provided by core network 2 may include connections to the Internet or external telephone services. Core network 2 can further track the location of communication equipment 4, enabling it to effectively contact (i.e., page) communication equipment 4 to transmit downlink data to it.
[0048] Base stations, as examples of network infrastructure equipment, can also be referred to as transceiver stations, nodeBs, e-nodeBs, eNBs, g-nodeBs, gNBs, and so on. In this regard, different terms are generally associated with different generations of wireless telecommunication systems that provide elements offering broadly comparable functionality. However, certain embodiments of this disclosure can be equivalently implemented in different generations of wireless telecommunication systems, and for simplicity, certain terms may be used regardless of the underlying network architecture. That is, the use of specific terms associated with certain exemplary implementations is not intended to indicate that these implementations are limited to a particular generation of networks most likely associated with that specific term.
[0049] New radio access technology (5G)
[0050] Figure 2 An example configuration of a wireless communication network is shown, which uses some terminology proposed for and used in NR and 5G. Figure 2 In this configuration, multiple Transmit and Receive Points (TRPs) 10 are connected to Distributed Control Units (DUs) 41, 42 via a connection interface represented as line 16. Each TRP 10 is arranged to transmit and receive signals via a wireless access interface within the available radio frequency bandwidth of the wireless communication network. Thus, within the range used for performing radio communication via the wireless access interface, each TRP 10 forms a cell of the wireless communication network represented by circle 12. Therefore, wireless communication devices 14 within the radio communication range provided by cell 12 can transmit signals to and receive signals from TRPs 10 via the wireless access interface. Each unit in the distributed units 41, 42 is connected to a central unit (CU) 40 (which may be referred to as a control node) via interface 46. The central unit 40 is then connected to a core network 20, which may contain all other functions required for transmitting data for communicating with wireless communication devices, and the core network 20 may be connected to other networks 30.
[0051] Figure 2The components of the wireless access network shown can be in a manner similar to that of... Figure 1 The example describes the operation of the corresponding components in an LTE network. It should be understood that... Figure 2 The operational aspects of the telecommunications network shown, as well as other operational aspects of networks discussed herein according to embodiments of this disclosure (not specifically described) (e.g., regarding specific communication protocols and physical channels for communication between different elements), can be implemented according to any known technology, such as methods currently used for implementing such operational aspects of wireless telecommunications systems, for example, according to relevant standards.
[0052] Figure 2 The TRP 10 may partially have functions corresponding to a base station or eNodeB in an LTE network. Similarly, the communication device 14 may have functions corresponding to the UE device 4 known for operation with an LTE network. Therefore, it should be understood that the operational aspects of the new RAT network (e.g., regarding specific communication protocols and physical channels used for communication between different components) may differ from those known in LTE or other known mobile telecommunications standards. However, it will also be understood that each of the core network components, base stations, and communication devices of the new RAT network will be functionally similar to the core network components, base stations, and communication devices of an LTE wireless communication network, respectively.
[0053] In terms of broad top-level functionality, connecting to Figure 2 The core network 20 of the new RAT telecommunications system shown can be widely considered to be related to... Figure 1 Corresponding to the core network 20 shown, and the corresponding central unit 40 and its associated distributed unit / TRP 10 can be broadly considered to provide the same... Figure 1 The function corresponding to base station 1. The term network infrastructure equipment / access node can be used to include these elements and more conventional base station type elements of wireless telecommunications systems. Depending on the application at hand, the responsibility for scheduling transmissions on the radio interfaces between the various distributed units and communication equipment may lie with the control node / central unit and / or distributed unit / TRP. Figure 2 The symbol represents a communication device 14 within the coverage area of the first communication cell 12. Therefore, the communication device 14 can exchange signaling with the first central unit 40 in the first communication cell 12 through one of the distributed units 10 associated with the first communication cell 12.
[0054] Furthermore, it should be understood that Figure 2 This is merely an example of a proposed architecture for a telecommunications system based on the new RAT, in which methods based on the principles described herein can be employed, and the functionality disclosed herein can also be applied to wireless telecommunications systems with different architectures.
[0055] Therefore, certain embodiments of this disclosure, as discussed herein, can be adapted to various different architectures, such as Figure 1 and Figure 2 The example architecture shown is implemented in a wireless telecommunications system / network. Therefore, it should be understood that the specific wireless telecommunications architecture in any given implementation is not of primary significance to the principles described herein. In this regard, certain embodiments of this disclosure can be described generally in the context of communication between network infrastructure devices / access nodes and communication devices, where the specific properties of the network infrastructure devices / access nodes and communication devices will depend on the network infrastructure used in the implementation at hand. For example, in some scenarios, the network infrastructure devices / access nodes may include base stations, such as… Figure 1 The LTE-type base station 1 shown is adapted to provide functionality according to the principles described herein, and in other examples, network infrastructure equipment may include... Figure 2 The control unit / control node 40 and / or TRP 10 of the type shown are adapted to provide functionality in accordance with the principles described herein.
[0056] Figure 3 Provided Figure 2 A more detailed diagram of some components of the network shown is provided. Figure 3 In Chinese, as a simplified representation, such as Figure 2 The TRP 10 shown includes a wireless transmitter 30, a wireless receiver 32, and a controller or control processor 34, which is operable to control the transmitter 30 and the wireless receiver 32 to transmit and receive radio signals to one or more UEs 14 within the cell 12 formed by the TRP 10. Figure 3 As shown, example UE 14 is shown as including a respective transmitter 49, receiver 48 and controller 44, controller 44 being configured to control transmitter 49 and receiver 48 to transmit signals representing uplink data to the wireless communication network via the radio access interface formed by TRP 10, and to receive downlink data as signals transmitted by transmitter 30 and received by receiver 48 according to normal operation.
[0057] Transmitters 30, 49 and receivers 32, 48 (and other transmitters, receivers, and transceivers described in the examples and embodiments of this disclosure) may include radio frequency filters and amplifiers, as well as signal processing components and devices, for transmitting and receiving radio signals according to, for example, 5G / NR standards. Controllers 34, 44 (and other controllers described in the examples and embodiments of this disclosure) may be, for example, microprocessors, CPUs, or dedicated chipsets, configured to execute instructions stored on a computer-readable medium such as non-volatile memory. The processing steps described herein may be executed, for example, by a microprocessor in conjunction with random access memory, operating according to instructions stored on a computer-readable medium. The transmitters, receivers, and controllers in Figure 3 These are schematically shown as individual elements for ease of representation. However, it should be understood that the functionality of these elements can be provided in a variety of different ways, such as using one or more appropriately programmed programmable computers, or one or more appropriately configured application-specific integrated circuits / circuit groups / chips / chipsets. As will be understood, infrastructure equipment / TRP / base stations and UE / communication equipment will typically include a variety of other elements associated with their operational functions.
[0058] like Figure 3 As shown, TRP 10 also includes a network interface 50 connected to DU 42 via physical interface 16. Therefore, network interface 50 provides a communication link for data and signaling traffic from TRP 10 to core network 20 via DU 42 and CU 40.
[0059] The interface 46 between DU 42 and CU 40 is referred to as the F1 interface, which can be a physical interface or a logical interface. The F1 interface 46 between the CU and DU operates according to specifications 3GPP TS 38.470 and 3GPP TS 38.473 and can be formed by fiber optic or other wired or wireless high-bandwidth connections. In one example, the connection 16 from TRP 10 to DU 42 is via fiber optic. The connection between TRP 10 and the core network 20 is often referred to as the backhaul, which includes the interface 16 from the network interface 50 of TRP 10 to DU 42 and the F1 interface 46 from DU 42 to CU 40.
[0060] eURLLC and NR-U
[0061] Systems incorporating NR technology are expected to support different services (or service types), characterized by varying requirements for latency, data rate, and / or reliability. For example, enhanced mobile broadband (eMBB) services are characterized by high capacity, requiring support up to 20 Gb / s. Ultra-reliable and low-latency communication (URLLC) services require latency of 1-10 Gb / s within 1 ms. -5With a reliability of 99.999% or higher (99.9999%), a single transmission of a 32-byte data packet is made from the radio protocol layer 2 / 3SDU entry point to the radio protocol layer 2 / 3SDU exit point of the radio interface [2]. Massive machine-type communication (mMTC) is another example of a service that can be supported by an NR-based communication network. In addition, the system may support further enhancements related to the Industrial Internet of Things (IIoT) to support services with new requirements for high availability, high reliability, low latency, and, in some cases, high-precision positioning.
[0062] Enhanced URLLC (eURLLC)[3][4] specifies functions requiring high reliability and low latency, such as factory automation, transportation, power distribution, etc. It should be understood that URLLC and eMBB will have different requirements for uplink control information (UCI). Therefore, one of the current goals of eURLLC is to enhance UCI to support URLLC, where the aim is to allow more frequent transmission of UCI, such as more hybrid automatic repeat request acknowledgment (HARQ-ACK) feedback per time slot, and to support multiple HARQ-ACK codebooks for different traffic services. Solutions identified as adapting to more frequent UCI without interrupting high-priority and low-latency data transmission using the Physical Uplink Shared Channel (PUSCH) may include multiplexing UCI to PUSCH repeats.
[0063] Another service that incorporates NR technology is 5G NR in unlicensed spectrum (NR-U)[5], which enables devices to utilize shared and unlicensed spectrum bandwidth. Features such as Listen Before Talk (LBT) as specified in [5] can be incorporated into the NR frame structure for NR-U operation in unlicensed bands. As described in [4], one of the goals of eURLLC is to coordinate the configured licensed (CG)PUSCH operation in eURLLC and NR-U.
[0064] Unlicensed access to channels in frequency bands
[0065] The following paragraphs provide an explanation of current recommendations for accessing communications from unlicensed frequency bands. In unlicensed frequency bands, two or more systems can operate to communicate using the same communication resources. As a result, transmissions from different systems can interfere with each other, especially when, for example, each different system is configured according to different technology standards (e.g., Wi-Fi and 5G). Of course, transmissions from systems operating according to the same standards can also cause interference. Therefore, for each transmitter operating in an unlicensed frequency band, there is a regulatory requirement to use the LBT protocol to reduce interference between different systems sharing that band (operating according to the same or different technology standards). In LBT, a device wishing to transmit data packets will first sense any energy level in the frequency band above a threshold to determine if any other device is transmitting, i.e., it is listening. If no transmission is detected, the device will then transmit its data packets. Otherwise, if the device detects a transmission from another device, it will back off and try again later.
[0066] In NR-U, channel access can be dynamic (also known as load-based access) or semi-static (also known as frame-based access). Dynamic channel access schemes consist of one or more Clear Channel Assessment (CCA) phases within a contention window, followed by a Channel Occupancy Time (COT) phase, such as... Figure 4 As shown. LBT is performed by the NR-U device (e.g., gNB or UE) that wishes to perform a transmission during the CCA phase. According to the CCA phase, the NR-U device listens for one or more CCA slots, and if no other transmission is detected after the CCA phase (i.e., the energy level is determined to be below a threshold for the duration of one or more CCA slots), the NR-U device enters the COT phase, in which the NR-U device can transmit its data packets in the COT resources. In Dynamic Channel Access (DCA), the CCA and COT phases can have different lengths between different systems, while in Semi-Static Channel Access, the CCA and COT phases have fixed time windows and are synchronized for all systems sharing the frequency band. More details about channel access in NR-U can be found in the co-pending European patent application EP 20187799.0 [6].
[0067] In NR-U, a device can be either an initiating device or a responding device. The initiating device obtains a COT by performing a CCA, and typically it initiates the first transmission, such as transmitting an uplink grant from the gNB. The responding device receives a transmission from the initiating device and responds to the initiating device with a transmission; for example, the UE receives an uplink grant and transmits the corresponding PUSCH. As will be understood, the UE can also be an initiating device, for example, when the UE is transmitting a configured grant (CG) PUSCH, and the gNB can be a responding device.
[0068] There are two types of Dynamic Channel Access (DCA), referred to as Type 1 and Type 2. In Type 1 DCA, counter N is generated as 0 and CW... p A random number between the values of CW and the competition window size CW. p Set up in CW min,p and CW max,p Between. The duration and value of COT {CW min,p CW max,p The value p depends on the Channel Access Priority Class (CAPC) of the transmission. CAPC can be determined, for example, by the QoS of the transmitted data packets. Type 1 DCA is performed by the initiating device, and once a COT is obtained, one or more responding devices can use Type 2 DCA for their transmissions within the COT. If the gap between a single transmission from two devices is less than a predefined value (e.g., 25 μs), Type 2 DCA may require a short CCA or may not require a CCA before transmission. If the gap is greater than this predefined value, such as 25 μs, the responding device needs to perform Type 1 DCA.
[0069] Figure 5 It provides the frequency-time relationship for transmission in unlicensed frequency bands. For example... Figure 5 The examples shown illustrate both Type 1 DCA and Type 2 DCA transmissions. Figure 5 In the example shown, at time t0, the gNB wants to send an uplink grant UG#1 to the UE to schedule PUSCH#1. The gNB performs Type 1 DCA starting from a contention window with four CCAs 51, such that for this example, random number N = 4, and no energy is detected during the contention window 52, thus acquiring a COT 54 between times t1 and t4. Then, as indicated by arrow 56, the gNB transmits UG#1 to the UE that schedules PUSCH#1 at time t3. If the interval between times t2 and t3 between UG#1 and the start of its PUSCH#1 transmission is less than a threshold, the UE receiving the uplink grant UG#1 can use Type 2 DCA; otherwise, the UE will have to perform Type 1 DCA. That is, if the granted PUSCH#1 is less than the threshold time of the gNB transmission of the uplink grant UG#1 or other gNB transmissions, the UE does not need to compete for resources on the unlicensed band by transmitting in the CCA and then in the COT according to Type 1 DCA.
[0070] like Figure 6As shown, there are three types of Type 2DCA, which are defined relative to the length of the gap 61 between the transmission 62 of the first device (initiating device) and the transmission 64 of the second device (responding device) within the COT, and therefore by whether the second responding device needs to perform CCA. These types are:
[0071] • Type 2A: The interval between two transmissions is greater than 16 μs and not greater than 25 μs, and the UE performs a single clear channel assessment (CCA) within this interval.
[0072] • Type 2B: The interval between two transmissions is no greater than 16 μs, and the UE performs a single CCA within this interval; and
[0073] • Type 2C: The gap between two emissions does not exceed 16 μs, and CCA is not required within this gap of 61 μs.
[0074] A single COT can be shared by multiple devices; that is, a gNB can initiate a COT, which can then be shared with one or more UEs. For example, a gNB can initiate a COT, then transmit a UL authorization to a UE, and the UE can then use that COT to transmit a PUSCH. A device using a COT initiated by another device may not need to perform a CCA, or may only need to perform a short CCA. Those skilled in the art will understand that a UE can also initiate a COT.
[0075] Rel-15 configured license
[0076] As will be fully understood by those skilled in the art, the UE uses the Physical Uplink Shared Channel (PUSCH) for uplink data transmission. The PUSCH resources used for transmitting the PUSCH can be scheduled by the gNB using Dynamic Grant (DG) or Configured Grant (CG).
[0077] In Dynamic Grant PUSCH (DG-PUSCH), when uplink data arrives at its buffer, the UE typically sends a scheduling request (SR) to the gNB. In response to receiving the SR, the gNB then sends an uplink grant to the UE, for example via downlink control information (DCI) in DCI format 0_0, 0_1, or 0_2 carried over the physical downlink control channel (PDCCH), where the uplink grant is a PUSCH scheduling resource. The UE then uses the scheduled PUSCH (i.e., DG-PUSCH) to transmit its uplink data.
[0078] Observations indicate that the use of DG-PUSCH introduces latency because the UE needs to initiate a SR (Streaming Service) and must wait for uplink clearance before scheduling PUSCH resources. For regular and periodic traffic, DG-PUSCH results in sending multiple SRs and uplink clearances, which is not an efficient use of resources. Therefore, recognizing the drawbacks of DG-PUSCH, Configured Granted PUSCH (CG-PUSCH) was introduced in NR (Radio Resource Control). In CG-PUSCH, periodic PUSCH resources are pre-configured for the UE using Radio Resource Control (RRC), allowing the UE to transmit its uplink data in any of these periodically occurring CG-PUSCH resources without requesting it from an SR. There are two types of CG-PUSCH:
[0079] · Type 1 CG-PUSCH Once the RRC has configured the CG-PUSCH resource, the UE can use it without activation; and
[0080] · Type 2CG-PUSCH CG-PUSCH resources are first configured by the RRC. If the UE receives an activated DCI, the UE can only use the CG-PUSCH resource. The activated DCI is a UL authorization with a configured Scheduling Radio Network Temporary Identifier (CS-RNTI). Once the CG-PUSCH is activated, the UE can use it until it is deactivated by another DCI. Type 2 CG-PUSCH provides better control for the gNB scheduler, thus enabling more efficient resource utilization.
[0081] In the time domain, CG-PUSCH consists of a period P. CG It consists of the number of repetitions K = {1, 2, 4, 8}, the duration L of the PUSCH, and the starting symbol offset relative to the slot boundary S of the PUSCH. Figure 7 An example is shown where CG-PUSCH has a period P. CG = 224 symbols (or 16 time slots), repetition K = 4, duration L = 9 symbols, and start symbols S = 3 symbols starting from the time slot boundary. CG-PUSCH consists of transmission occasions (TOs), where TOs are the opportunities for the UE to transmit uplink data. It should be noted that if the UE has no uplink data to transmit, the UE does not need to use the TO, i.e., the CG-PUSCH resource. For example, in time slot n, the UE has no uplink data, so it does not transmit anything in the TO of that CG cycle, but in the next CG cycle starting from time slot n+16, the UE has uplink data, so it uses the TO in that CG cycle to transmit four repetitions of the uplink data.
[0082] The first TO in the CG cycle is associated with the redundant version RV=0. If the repetition K>1, each TO in the CG cycle is associated with an RV pattern configured in the RRC, where the RV pattern can be {0, 2, 3, 1}, {0, 3, 0, 3}, or {0, 0, 0, 0}. The RV pattern is configured in the RRC parameter repK-RV. For example, in Figure 7 In this context, the RV mode is {0, 2, 3, 1}. The first PUSCH emission in a CG cycle must always begin with RV = 0. For repetition K = 8, the RV mode cycles after the fourth repetition; that is, the RV mode restarts after the fourth repetition. For example, in... Figure 8 In this context, the RV mode = {0, 2, 3, 1}, and K = 8 repetitions. Here, the UE cycles through RV during the fifth repetition, where the RV mode restarts at the fifth TO of the CG cycle in time slot n+4.
[0083] Because HARQ is used for PUSCH transmissions, each PUSCH is associated with a HARQ process number (HPN), of which there are 16 HARQ processes, i.e., HPN = 0 to 15. In DG-PUSCH, the HPN is indicated in the UL authorization. For CG-PUSCH, since there is no UL authorization, each CG cycle is associated with an HPN and depends on the start symbol O of the first TO in the CG cycle. CG (in units of sign), period P CG (in symbols) and the number of HARQ processes N configured for CG-PUSCH HARQ [7] (That is, gNB can configure fewer than 16 HARQ processes for CG-PUSCH), i.e.:
[0084]
[0085] in It is the floor function and O CG The first symbol of the first time slot relative to the radio frame with SFN=0.
[0086] UL authorization is used to schedule CG-PUSCH retransmissions. That is, DG-PUSCH is used for retransmissions of CG-PUSCH that were not successfully decoded at the gNB. If the UE is within the pre-configured timer T... CG-ACK If no UL authorization for retransmitting CG-PUSCH is received, the UE will consider that it has successfully received CG-PUSCH.
[0087] Rel-16eURLLC CG-PUSCH
[0088] Since the first CG-PUSCH transmission must use a TO with RV=0, if the UE misses that TO, it may be unable to transmit any PUSCH during that CG cycle. For example, refer back to the reference. Figure 7 If uplink data arrives at the UE buffer in time slot n+1, the UE may only be ready to transmit the PUSCH in time slot n+2. However, the TO in time slot n+2 corresponds to RV=3, so the UE cannot begin its PUSCH transmission. It then must wait until the next CG period in time slot n+16, when the TO with RV=0, to begin its transmission. This introduces a delay to the PUSCH transmission, which may not meet the strict latency requirements of URLLC.
[0089] To improve reliability, as mentioned above, repetition is used to transmit PUSCH. For CG-PUSCH, if uplink data does not arrive before the first TO of the CG cycle, the UE may not be able to transmit the required number of repetitions, even if there are multiple TOs with RV=0 within that CG cycle. For example, in Figure 9 In this configuration, the CG-PUSCH is set to K=4 repetitions and RV pattern {0, 3, 0, 3}, allowing the first PUSCH transmission to begin in two TOs (i.e., the first TO and the third TO). Uplink data arrives at the UE buffer at the end of slot n, thus missing the first TO of the CG cycle. Since the UE must begin its PUSCH transmission in a TO with RV=0, the PUSCH is transmitted in slot n+2, i.e., in the nearest TO with RV=0. However, only two TOs remain in the CG cycle, and therefore the UE can only transmit two of the target four repetitions. This reduced PUSCH repetition transmission may not meet the stringent reliability requirements of URLLC.
[0090] Recognizing the limitations of Rel-15 CG-PUSCH, Rel-16 eURLLC introduced multiple CG-PUSCH, where a UE can be configured with up to 12 CG-PUSCH, each of which can be configured independently. This allows different CG-PUSCHs to start at different times, giving the UE multiple opportunities to transmit its PUSCH. For example, in... Figure 10In this configuration, the UE is equipped with four CG-PUSCHs, labeled CG#1, CG#2, CG#3, and CG#4, with each repeating K=4. These CG-PUSCHs are configured such that they begin within one slot offset from each other. In slot n+1, uplink data arrives at the UE's buffer, and the possible TOs that the UE can use to begin its PUSCH transmission are the third TO of CG#1 (slot n+2), the first TO of CG#3 (slot n+2), and the first TO of CG#4 (slot n+3). To ensure K=4 repetitions, the UE could use either CG#3 or CG#4, but since CG#3 provides the lowest latency, the UE chooses CG#3 for its PUSCH transmission, thus ensuring K=4 repetitions and minimizing latency. Those skilled in the art will understand that, Figure 10 The interleaving of multiple CG-PUSCH resources shown is just one possible configuration to ensure K repetitions are sent with minimal latency. The gNB is free to configure other configurations, as each CG-PUSCH can be configured individually.
[0091] For type 2 CG-PUSCH, a CG-PUSCH can be activated individually using the four-digit HPN field in the UL authorization. For deactivation, one or more CG-PUSCHs can be deactivated using the 16 states in the HPN field, where each state can be configured to indicate a combination of CG-PUSCHs used for deactivation.
[0092] There are two types of PUSCH mappings:
[0093] Type A: Where PUSCH begins at the start of the time slot, i.e., symbol offset S = 0; and
[0094] Type B: Where PUSCH can start from any symbol within a time slot, i.e., S = 0 to 13.
[0095] In Rel-15, slot-based PUSCH repetition, called PUSCH aggregation, was introduced to improve the reliability of PUSCH transmission. Figure 11 An example is shown where a PUSCH aggregation from slot n to slot n+3 is used, with a type B PUSCH of four symbol durations (i.e., L=4) starting two symbol offsets from the slot boundary, and repeated four times, i.e., K=4. The number of repetitions of the PUSCH aggregation is configured by RRC.
[0096] In PUSCH aggregation, i.e., slot-based PUSCH repetition, where the PUSCH duration is shorter than the slot, the time interval between repetitions can be observed. For Figure 11In the example, PUSCH is repeated at the slot level, leaving a 10-symbol gap between consecutive repetitions. This gap introduces latency, which is unacceptable for URLLC. Recognizing this, in Rel-16eURLLC, enhanced type B PUSCH repetition (e-type B PUSCH) was introduced, where PUSCH repetitions are repeated back-to-back, thereby minimizing latency while improving reliability. Figure 12 An example is shown where Rel-16 PUSCH repetition is used, with four symbol duration PUSCHs having a two-symbol offset from the slot boundary, L=4, repeated four times, i.e., K. N =4. Here, there are no gaps between each repetition, thus completing the entire repetition within 16 symbols compared to 56 symbols (four time slots) when using PUSCH aggregation. Rel-16eURLLC's DG-PUSCH and CG-PUSCH support enhanced Type B PUSCH repetition. In DG-PUSCH, the number of repetitions is indicated in the UL license, while for CG-PUSCH, the number of repetitions is the RRC configured in the repK parameter.
[0097] Because e-type B PUSCHs can begin at any symbol within a time slot, some of their repetitions may cross time slot boundaries or conflict with invalid Orthogonal Frequency Division Multiplexing (OFDM) symbols (e.g., downlink symbols), and these PUSCHs are segmented. For example, PUSCH repetitions scheduled by UL authorization or configured for CG-PUSCHs are known as nominal repetitions. If segmentation occurs on a nominal PUSCH and it is segmented into two or more PUSCH segments, these segments are called actual repetitions K. A That is, these actual repetitions are the actual PUSCH repetitions transmitted, which can therefore be greater than the nominal number of repetitions, i.e., the predetermined number of repetitions. The PUSCH duration L and nominal number of repetitions K are scheduled by UL authorization or configured for CG-PUSCH. N The absolute total duration of the PUSCH emission is given; that is K. N ×L is the duration of the entire PUSCH transmission, and therefore any portion of the PUSCH transmission that conflicts with an invalid OFDM symbol is discarded. Figure 13 Two examples of PUSCH segmentation are shown. At time t1, the emission has K N =4, L=4 PUSCH 131, where the third nominal PUSCH repeat crosses the slot boundary at time t4. Therefore, the third nominal PUSCH repeat is segmented into two PUSCH repeats, so the actual number of repeats K A =5. At time t9, another has K NPUSCH 132 with L=2 and L=6 is emitted, wherein the first nominal PUSCH repeats at time t 10 and t 11 There is a conflict with two DL (or invalid) symbols. Therefore, the first nominal PUSCH repeat is segmented into two PUSCH repeats, so the actual number of repeats K A =3. Because K N ×L = 12 OFDM symbols, which is the total duration of PUSCH transmission 132, therefore at time t 10 and t 11 Two PUSCH symbols that conflict with a DL (or invalid) symbol are discarded.
[0098] In Rel-15, the physical layer has no priorities; when two UL transmissions collide, their information is multiplexed and transmitted using a single channel. Possible collisions include those between the Physical Uplink Control Channel (PUCCH) and another PUCCH, and between PUCCH and PUSCH. It should be noted that Rel-15 defines priorities for the MAC layer, with 16 priority levels.
[0099] The UE can be configured to provide eMBB and URLLC services. Because eMBB and URLLC have different latency requirements, their uplink transmissions may conflict. For example, an urgent URLLC packet may arrive after an eMBB uplink transmission has already been scheduled, requiring immediate scheduling, and thus its transmission may conflict with the eMBB transmission. To handle such intra-UE conflicts with different latency and reliability requirements, two physical layer priorities, PUCCH and PUSCH, were introduced for uplink transmissions in Rel-16. In Rel-16, intra-UE priorities are used; that is, when two UL transmissions with different physical layer priority levels (L1 priority) conflict, the UE will drop the lower-priority transmission. If two UL transmissions have the same L1 priority, the UE can reuse the Rel-15 procedure (i.e., the UL transmissions are multiplexed and transmitted using a single channel). For CG-PUSCH, the L1 priority is the RRC configured for each CG-PUSCH in the RRC parameter phy-PriorityIndex-r16.
[0100] Rel-16-NR-U CG-PUSCH
[0101] Because transmission requires LBT, the UE may not be able to access CG-PUSCH transmission occasions (TOs), especially those associated with RV=0. Therefore, recognizing this, in Rel-16 NR-U, the TO is increased in each CG period by extending the CG period to slots cg-nrofSlots-r16 (1 to 40), where each slot contains cg-nrofPUSCH-InSlot-r16 (1 to 7) consecutive CG-PUSCHs. The parameters cg-nrofSlots-r16 and cg-nrofPUSCH-InSlot-r16 are RRCs configured according to the CG-PUSCH. The UE can begin PUSCH transmission in any of these CG-PUSCH resources within the CG period, instead of being limited to a specific TO with RV=0 as described above in legacy systems. Therefore, in each CG cycle, the UE is effectively provided with cg-nrofSlots-r16×cg-nrofPUSCH-InSlot-r16 flexible TOs, and thus the UE has multiple opportunities for the LBT to attempt to transmit its PUSCH. It should be noted that in 3GPP, these TOs are referred to as multi-CG-PUSCH, but to avoid confusion with the Rel-16eURLLC multi-CG-PUSCH described above, these TOs are referred to herein as flexible TOs (F-TOs). Figure 14 An example is shown where P CG = 224 symbols (16 time slots), S = 2 symbols, L = 4 symbols, cg-nrofSlots-r16 = 4, cg-nrofPUSCH-InSlot-r163, 12 flexible TOs per CG cycle. At the end of time slot n, UL data arrives at the UE buffer, and the UE attempts to transmit it in the next F-TO, i.e., TO#3 in time slot n+1. However, Figure 14 In the example shown, the UE failed the LBT procedure and therefore attempted another LBT on TO#4, which succeeded in this case. The UE then transmits two PUSCHs in slot n+1 using TO#4 and TO#5 (this can be used for different Ts). B (or HPN). At the end of slot n+2, further UL data arrives at the UE buffer and attempts LBT on the next F-TO (i.e., TO#9 in slot n+3) and succeeds, thus transmitting PUSCH in that slot.
[0102] For CG-PUSCH transmissions, the UE may need to perform a CCA and initiate a COT. The UE can share the COT with the gNB, for example, by allowing the gNB to send a feedback signal for its CG-PUSCH transmissions. The DL resources within the gNB's COT are indicated by the UE in the CG-UCI. Here, the UE indicates the slot offset O for which a DL transmission can begin.DL and the time slot duration L of DL transmission DL The index of the entries in the lookup table. The lookup table is configured using C++. DL The entries are configured with RRC, and they are sent in the cg-COT-SharingList-r16 parameter. An entry in this lookup table indicates "not shared". Slot offset O DL The end of the time slot relative to the CG-UCI containing the COT indicating shared DL resources. As shown in Table I, C DL = Example configuration of "cg-COT-SharingList-r16" with 4 entries
[0103] Table I: DL resources for COT sharing initiated by UE (cg-COT-SharingList-r16)
[0104] index <![CDATA[O DL (time slot) <![CDATA[L DL (time slot) 0 Not shared Not shared 1 3 2 2 2 4 3 1 1
[0105] Figure 15 This section illustrates example operations using the example configuration in Table I. Here, we label offsets and DL resources according to their indexes; that is, O DL 1 O DL 2 And O DL 3 These are the offsets for indices 1, 2, and 3, respectively. Similarly, DL#1, DL#2, and DL#3 are the DL resources for indices 1, 2, and 3, respectively, each with a duration L. DL 1 L DL 2 and L DL 3 The resource at index 0 is not shown because it indicates "not shared". Figure 15 In this scenario, the UE has four F-TOs (i.e., cg-nrofSlots-r16 = 2 and cg-nrofPUSCH-InSlot-r16 = 2). The UE then attempts to acquire TO#2 for its PUSCH transmission, thereby acquiring a COT of seven slot lengths. During PUSCH transmission, the UE multiplexes a CG-UCI containing COT sharing information, which indicates that the gNB can use one of the three available DL resources for its HARQ-ACK feedback of the PUSCH transmission. Because the CG-UCI is in slot n+1, the slot offset is O. DL 1 O DL 2 And O DL 3 Relative to the end of time slot n+1.
[0106] In Rel-15 and Rel-16 eURLLC, the HPN and RV transmitted for each CG-PUSCH are fixed for each TO and the gNB is known. However, due to the use of flexible TOs in Rel-16 NR-U, the UE can use any TO for the first PUSCH transmission, and different TOs can be transmitted within the CG cycle. B In the case of (i.e., having different HPNs), the gNB needs to know the HPN and RV of each of these CG-PUSCHs. To provide this information to the gNB, CG uplink control information (CG-UCI) is introduced for Rel-16 NR-U, which includes the following fields [8]:
[0107] • HARQ process number (HPN), which is indicated using 4 bits of CG-UCI;
[0108] • Redundant version (RV), which is indicated using 2 bits of CG-UCI;
[0109] • New Data Indicator (NDI), which uses 1 bit of CG-UCI for indication; and
[0110] • COT shared information, its usage is equal to log2C DL The number of bits in the CG-UCI is used to indicate this, where C DL It is the number of entries in the lookup table, indicating the location of DL resources that the gNB can use in a COT initiated by the UE.
[0111] CG-UCI is multiplexed into CG-PUSCH transmission.
[0112] In Rel-15 and Rel-16eURLLC, implicit HARQ-ACK feedback is used for CG-PUSCH, where NACK is implicitly indicated as UL authorization for CG-PUSCH scheduling retransmission, and timer T CG-ACK Used to implicitly indicate ACK.
[0113] For Rel-16 NR-U, explicit HARQ-ACK is used for CG-PUSCH, carried by Downlink Feedback Information (DFI). The DFI is carried by the PDCCH and contains a 16-bit bitmap indicating ACK / NACK for each HPN, where "1" indicates ACK and "0" indicates NACK. HARQ-ACK feedback in the DFI applies not only to CG-PUSCH but also to messages transmitted at least T times prior to the start of the DFI. DFI-Delay The symbol DG-PUSCH. T DFI-Delay The RRC is configured in parameter cg-minDFI-Delay-r16. Figure 16An example is shown where the CG cycle consists of four F-TOs, and the UE transmits PUSCH to TO#0, TO#2, and TO#3 respectively with HPN=0, HPN=10, and HPN=8. This T DFI-Delay =7 symbols, and in this example, the DFI can only provide HARQ-ACKs for TO#0 and TO#2, which, according to their HPNs, are indicated in the first and eleventh positions of the DFI bitmap, respectively (these are in...). Figure 16 (Indicated as bold and underlined). Because the end of TO#3 is less than T before the start of DFI. DFI-Delay The symbol used for HARQ-ACK in TO#3 is not represented in DFI, and is indicated as "0" regardless of whether it is ACK or NACK.
[0114] The DFI does not indicate any uplink resources for the UE, therefore a separate CG-PUSCH resource is used to transmit the CG-PUSCH retransmission. The gNB uses the NDI and HPN fields of the CG-UCI to determine if the CG-PUSCH is a retransmission. The UE can also determine the RV of the retransmission (or the first transmission), as it can be indicated in the CG-UCI.
[0115] Because the gNB must perform LBT, especially when DFI is not transmitted within the COT initiated by the UE, DFI transmission is not guaranteed. Retransmission timer T CG-ReTx This feature was introduced for Rel-16 NR-U and begins after the CG-PUSCH is transmitted. If the retransmission timer expires and the UE does not receive an explicit HARQ-ACK (i.e., DFI) from the gNB, the UE will retransmit the CG-PUSCH.
[0116] In Rel-16 NR-U, CG-UCI is transmitted in each PUSCH repetition, where CG-UCI indicates HPN, RV, NDI, and COT shared information. In URLLC, PUSCH repetition is introduced to improve the reliability of data transmission. Because CG-UCI may carry different RV information in each PUSCH repetition, it cannot benefit from any combined gain from these repetitions and may therefore lack sufficient reliability to meet the requirements of URLLC.
[0117] Proper decoding of the CG-UCI is necessary to enable PUSCH decoding because the CG-UCI signals some parameters required for PUSCH decoding (e.g., the CG-UCI indicates the RV applied to PUSCH transmission, i.e., which set of parity bits and system bits is included in the PUSCH). Therefore, if the CG-UCI is unreliable, the PUSCH associated with it is also unreliable, and URLLC latency and reliability requirements may not be met. Embodiments of this technology propose methods to increase the reliability of the CG-UCI to, for example, meet URLLC latency and reliability requirements. Embodiments of this technology seek to ensure that the reliability of the CG-UCI is improved so that the CG-UCI is not the weakest link with respect to PUSCH reliability.
[0118] Improved URLLC UCI reliability
[0119] Figure 17 Partial schematic flowchart representations and partial message flowchart representations of a wireless communication network including communication device 171 and infrastructure device 172 according to at least some embodiments of the present technology are shown. Communication device 171 is configured to transmit data to or receive data from the wireless communication network via a wireless access interface provided by the wireless communication network, for example, to or from infrastructure device 172. Specifically, communication device 172 may be configured to transmit data (e.g., Ultra-Reliable Low-Latency Communication (URLLC) data) to the wireless communication network (e.g., to infrastructure device 172) via a wireless access interface. Communication device 171 and infrastructure device 172 each include transceivers (or transceiver circuits) 171.1, 172.1 and controllers (or controller circuits) 171.2, 172.2. Each controller in controllers 171.2, 172.2 may be, for example, a microprocessor, CPU, or dedicated chipset.
[0120] like Figure 17As shown in the example, the transceiver circuitry 171.1 and controller circuitry 171.2 of communication device 171 are combined and configured to operate 173 according to a configured licensed (CG) operation mode, which includes communication device 171 configured to determine 174 (e.g., via an activation indication or other such command received from a wireless communication network, such as from infrastructure device 172) a sequence of instances of uplink communication resources of a wireless access interface, and to transmit 175 signals to the wireless communication network (e.g., infrastructure device 172) in at least one instance of the sequence of instances of uplink communication resources of the wireless access interface. The system is configured to transmit uplink data 176 to a wireless communication network (e.g., to infrastructure device 172) in two or more instances of an instance sequence of uplink communication resources of the radio access interface, as multiple repetitions of uplink data (where each instance may contain one or more repetitions of the same PUSCH), and to transmit one or more versions of uplink control information CG-UCI from multiple versions of uplink control information CG-UCI to the wireless communication network (e.g., from infrastructure device 172), each version of CG-UCI being associated with multiple instances of an instance sequence of uplink communication resources of the radio access interface. Here, communication device 171 is configured to transmit uplink data 176 and 177 and CG-UCI such that during the transmission of uplink data 176, one or more versions of CG-UCI are transmitted multiple times. Here, CG-UCI can be understood as a UCI associated with the CG operating mode, but it does not specifically carry CG-related information; for example, as mentioned above, CG-UCI may also carry COT sharing information.
[0121] In at least some embodiments, uplink data transmission may be URLLC data transmission, and the information indicated by one or more CG-UCI indicators is specific to URLLC transmission. However, those skilled in the art will understand that embodiments of this technology can be equally applied to transmissions other than URLLC transmissions, such as eMBB transmissions or unlicensed band transmissions (NR-U), and therefore one or more new indicators in the CG-UCI can be equally used for transmissions of data related to services other than URLLC.
[0122] In at least some embodiments, each of the multiple versions of CG-UCI indicates different control information, and wherein each instance of a sequence of instances of uplink communication resources of the radio access interface associated with a version of CG-UCI is associated with the same control information indicated by said version of CG-UCI. Here, the control information may include a redundant version from a plurality of redundant versions (CVs).
[0123] Essentially, such as Figure 17 The example shown in this embodiment of the technique proposes that the CG-UCI can be repeated multiple times consecutively within a longer set of PUSCH repetitions. The reliability of the CG-UCI encoding can then be increased within that consecutive number of repetitions by repeating the CG-UCI within those PUSCH repetitions. It is necessary to repeat the CG-UCI within PUSCH repetitions having the same characteristics (e.g., RVs), as there would otherwise be no benefit to the repetition; to increase the reliability of the CG-UCI, CG-UCIs indicating different RVs, etc., are not composable at the receiver (e.g., gNB). Although this document describes RVs as information within the CG-UCI that changes between PUSCH repetitions and therefore requires the CG-UCI to be repeated within PUSCH repetitions, those skilled in the art will understand that this can be any area of the CG-UCI other than (or beyond) RVs.
[0124] In at least some arrangements of embodiments of this technology, CG-UCI information can be reused for X. UCIREP Physical resources of the unit. PUSCH associated with CG-UCI for those X UCIREP The duplicates have the same characteristics (where “characteristics” include HPN, RV, NDI and COT shared information).
[0125] For example, CG-UCI for X UCIREP The time slots were repeated, and PUSCH also applied to those X slots. UCIREP Time slot repetition. (In, for example...) Figure 18 In the exemplary embodiment shown, for a PUSCH with K = 8 repetitions, X UCIREP =2, although those skilled in the art will understand X UCIREP It can be greater than 2, and this can indeed increase the reliability of CG-UCI, but at the cost of increased overhead and latency. For example, RV=0 for the 1st and 2nd reuses, RV=3 for the 3rd and 4th reuses, RV=2 for the 5th and 6th reuses, and RV=1 for the 7th and 8th reuses.
[0126] In some arrangements of embodiments of this technology, the unit of physical resources is a time slot. In other words, one or more transmit versions of CG-UCI are repeated once or more within multiple time slots of the radio access interface, wherein each time slot contains one of two or more repeated instances carrying uplink data. This operating mode is as follows: Figure 18 As shown.
[0127] In some other arrangements of embodiments of this technology, the unit of physical resources is a sub-time slot. In other words, one or more transmit versions of CG-UCI are repeated once or more within multiple time-division sub-time slots of the radio access interface, wherein each time-division sub-time slot contains one instance of one of two or more repeated instances carrying uplink data. In such an arrangement, PUSCH occupies a sub-time slot, which may, for example, have a duration of 7 OFDM symbols, and CG-UCI occupies OFDM symbols within the sub-time slot. This operating mode is similar to the above regarding… Figure 18 The description of the layout differs in that the timeline is enumerated in units of sub-slots rather than in units of time slots.
[0128] from Figure 18 It is evident from this that the gNB needs to receive and buffer multiple time slots before it can decode the PUSCH. For example, see reference... Figure 18 Before the gNB can decode the CG-UCI and therefore the PUSCH, it needs to buffer the first and second time slots. That is, to process the PUSCH repetition RV0 (repeated across time slots A and B), the gNB needs to receive the CG-UCI in time slots A and B (and combine the CG-UCI in time slots A and B). Once it has received the CG-UCI repeated across time slots A and B, the gNB can determine that RV0 has been used to encode the PUSCH in time slots A and B, and therefore performs physical channel processing for the PUSCH repeated across time slots A and B. Therefore, in this example, the gNB can buffer the first and second time slots at time T. B Physical channel processing begins for the PUSCH received in time slots A and B. The gNB must buffer the PUSCH across time slots A and B until T. B Then the gNB will know how to perform physical channel processing on the buffered PUSCH. It should be noted here that physical channel processing requires functions such as determining which parity bits and system bits are included in the PUSCH and the interleaver mode applied to the PUSCH physical channel bits.
[0129] In some other arrangements of embodiments of this technology, the unit of physical resources is a transmission instance. In other words, one or more transmission versions of CG-UCI are repeated once or more in one or more instances of the uplink communication resources of the radio access interface.
[0130] like Figure 19 As shown, if the repetitions of CG-UCI are interleaved relative to the PUSCH they refer to, the above gNB buffering requirement can be avoided. Figure 19 It is shown that:
[0131] • Slot A—CG-UCI indicates RV0. This CG-UCI applies to PUSCH in slots A and B. It should be noted that this CG-UCI is not repeated, therefore there is no repeating gain in this slot. Because there is no repeating gain in this slot, the performance of PUSCH decoding in slots A and B may be compromised. This is unlikely to be a serious problem (CG-UCI will be decoded correctly in most cases, and even if not, it is very likely that PUSCH will be successfully decoded based on the other 6 slots: slot C->G);
[0132] • In time slot B, time slot B-CG-UCI represents the RV (etc.) applied in time slot C;
[0133] • The C-CG-UCI in time slot C is the same as that in time slot B, therefore the CG-UCI in time slots B and C can be combined. The PUSCH in time slots C and D can be generated from time T. C Decoding begins because the gNB knows the time T based on the repeated decoding of the CG-UCI from time slots B and C. C RV applied to time slots C and D; and
[0134] • Time slot G — The CG-UCI in time slot G is associated with the PUSCH in time slot G. Alternatively, the CG-UCI in time slot G can be associated with the first PUSCH of a subsequent set of repeated PUSCHs (i.e., the CG-UCI in time slot G can be associated with the PUSCH in "time slot A" of a subsequent set of 8 repeated PUSCHs).
[0135] Therefore, as Figure 19 As shown in the example, at least one CG-UCI repeat of at least one transmission version of CG-UCI is included in the transmission of uplink data earlier than the earliest of two or more instances associated with at least one transmission version of CG-UCI.
[0136] CG-UCI repetition can occur within the first repetition of a set of PUSCH repetitions, all of which are encoded using the same RV. In this case, the gNB can reliably repeat decoding the CG-UCI within the first PUSCH repetition, and then repeat decoding all subsequent PUSCH repetitions encoded using the same RV. In other words, all CG-UCI repetitions of at least one emission version of the CG-UCI are included in the earliest instance of the two or more instances associated with at least one emission version of the CG-UCI. An example of this arrangement is as follows: Figure 20 As shown. Figure 20 It is shown that:
[0137] • Slot A — This is the first slot in a pair (two) PUSCHs, both of which are encoded using RV0. Therefore, this slot contains two repetitions of the CG-UCI indicating RV0.
[0138] Once the gNB has decoded these repeating CG-UCIs, it reliably knows that it should be used to decode the RV of the PUSCH in slots A and B.
[0139] • Slot B — This is not the first slot of a pair of repeating PUSCHs sharing the same RV, therefore this slot does not contain CG-UCI; and
[0140] • Slot C — For slot A, although RV3 is applied to the PUSCH repetition in slots C and D, the repeated CG-UCI represents RV3;
[0141] ·etc.
[0142] In some arrangements of embodiments of this technology, when RV changes, CG-UCI repeats occur within the central portion of the PUSCH repeat (e.g., Figure 20 (As shown). In other words, all CG-UCI duplicates of at least one launch version of CG-UCI are substantially located in the middle of the earliest of two or more instances associated with at least one launch version of CG-UCI.
[0143] Figure 20 The CG-UCI repeat is shown as an intermediate repeat of the PUSCH repeat, but those skilled in the art will understand that the CG-UCI repeat may alternatively be located within other parts of the PUSCH repeat. Figure 21 An example is shown where the CG-UCI repeat is located in the start and end symbols (OFDM symbol or SC-FDMA symbol) of the slot containing the PUSCH repeat.
[0144] In some other arrangements of embodiments of this technology, when RV changes (e.g.) Figure 21 As shown), CG-UCI repetitions occur within the first and last symbols (OFDM or SC-FDMA) of the PUSCH repetition. In other words, all CG-UCI repetitions of at least one launch version of CG-UCI are substantially located at at least one end of the earliest instance of two or more instances associated with at least one launch version of CG-UCI.
[0145] In some other arrangements of embodiments of this technology, the PUSCH is transmitted along with a limited number of CG-UCIs within OFDM or SC-FDMA symbols, and additional CG-UCIs are transmitted within other OFDM or SC-FDMA symbols. In other words, a first CG-UCI repetition of at least one transmitted version of the CG-UCI is located within the earliest instance of two or more instances associated with at least one transmitted version of the CG-UCI, and a second CG-UCI repetition of at least one transmitted version of the CG-UCI is temporally adjacent to the earliest instance of two or more instances associated with at least one transmitted version of the CG-UCI (i.e., outside the CG-PUSCH resource, e.g., immediately following). For example, the gNB configures the UE with a 12-symbol OFDM symbol PUSCH containing 2 OFDM symbol CG-UCIs, where the 12 OFDM symbols begin with the first OFDM symbol of the time slot. This arrangement can be configured using existing Rel-16 PUSCH configuration signaling. The UE is further configured to transmit CG-UCI within the last two OFDM symbols, where the CG-UCI carries the same control information as the previously configured CG-UCI. Therefore, the gNB can combine the two CG-UCIs. The advantage of this example is that it minimizes specification changes and simplifies implementation.
[0146] In an alternative example, a repeated CG-UCI can be transmitted earlier than the earliest instance among two or more instances associated with at least one transmitted version of the CG-UCI. In other words, the first CG-UCI repeat of at least one transmitted version of the CG-UCI is located within the earliest instance among two or more instances associated with at least one transmitted version of the CG-UCI, and the second CG-UCI repeat of at least one transmitted version of the CG-UCI is temporally earlier than the earliest instance among two or more instances associated with at least one transmitted version of the CG-UCI. For example, the gNB configures the UE with a 12-symbol PUSCH containing 2 OFDM symbol CG-UCIs, where the 12 OFDM symbols begin with the third OFDM symbol in the time slot. This arrangement can be configured using existing Rel-16 PUSCH configuration signaling. The UE is further configured with CG-UCI transmission within the first two OFDM symbols, where the CG-UCI carries the same control information as the control information contained within the previously configured CG-UCI. Therefore, the gNB can combine the two CG-UCIs.
[0147] Typically, in situations as described above... Figure 20 and Figure 21In the arrangement of the described technical embodiment, CG-UCI repetitions occur within some known locations of PUSCH repetitions with RV variations. In other words, all CG-UCI repetitions of one or more transmit versions of CG-UCI are located at the location of the earliest instance among two or more instances associated with at least one version of CG-UCI known in the wireless communication network.
[0148] In some arrangements of embodiments of this technology, CG-UCI repetition may occur within the first PUSCH repetition (or the first few repetitions), and subsequent PUSCH repetitions may not carry CG-UCI or carry fewer information bits within the CG-UCI. In other words, all CG-UCI repetitions of all transmitted versions of CG-UCI are included in the earliest instance of two or more instances.
[0149] This arrangement allows the gNB to benefit from the repetitive decoding gain of CG-UCI and eliminates the need for the gNB to buffer the PUSCH. Figure 22 An operational example of this arrangement is shown, where the CG-UCI for all PUSCH repetitions is transmitted within the first two time slots of an 8-time-slot PUSCH. Because the gNB receives the CG-UCI early, it can repeatedly decode the CG-UCI before buffering the associated PUSCH. Figure 22 It is shown that:
[0150] • Slot A—The CG-UCI indicating RV0 is repeated twice. The associated PUSCH repeats are emitted in slots A and B. It should be noted that these PUSCHs are significantly truncated through the CG-UCI emission. However, note that the total available resources for PUSCH resource elements are... Figure 18 The same in; in Figure 22 In the game, the position of CG-UCI has changed, but the overall proportion of resources used by CG-UCI remains the same.
[0151] • Time slot A—indicates that the CG-UCI of RV3 is repeated twice. The associated PUSCH is transmitted in time slots C and D; and
[0152] • Time slots C and D — transmit in time slot C using the PUSCH of RV3 and repeat in time slot D;
[0153] ·etc.
[0154] Figure 23 An alternative arrangement of an embodiment of this technology is shown. Figure 23The diagram illustrates that a cluster of repeating CG-UCIs can be transmitted at the beginning of a set of PUSCH repeats, and a second cluster can be transmitted later within that set of PUSCH repeats. In other words, all CG-UCI repeats in one or more transmitted versions of CG-UCI are included in the earliest instance of two or more instances, and all other CG-UCI repeats in a transmitted version of CG-UCI are included in at least one later instance of two or more instances. This arrangement avoids situations where one redundant version of the PUSCH is significantly adversely affected, for example, due to channel fading during the transmission of that redundant version of the PUSCH.
[0155] Although the above-described arrangement of embodiments of this technology has demonstrated how the reliability of CG-UCI can be increased when PUSCH is repeated through the repetition of CG-UCI, the UE needs to know that the boundary of the new CG-UCI should be within the PUSCH repetition. It is recommended that CG-UCI be repeated in known PUSCH repetitions or follow a predefined order. In other words, one or more transmit versions of CG-UCI are repeated once or more in at least one of two or more instances, at least one of which is known to the wireless communication network. Alternatively (or additionally), one or more transmit versions of CG-UCI are repeated once or more in at least one of two or more instances according to a predefined pattern known to the wireless communication network.
[0156] A known implementation of a PUSCH repetition or predefined order is that the CG-UCI begins with the first PUSCH repetition and repeats in two consecutive PUSCH repetitions; for example, if there are 4 PUSCH repetitions, the 1st and 2nd repetitions have the same CG-UCI, and the 3rd and 4th repetitions have the same CG-UCI, but the CG-UCI of the 3rd and 4th repetitions may be different from that of the 1st and 2nd repetitions. Here, the gNB can then combine the CG-UCI of the 1st and 2nd repetitions with that of the 3rd and 4th repetitions. An example of a predefined order is that each odd-numbered repetition has the same CG-UCI.
[0157] The predefined sequence or known PUSCH repetition of the repeating CG-UCI can be configured by RRC, signaled in the active DCI, or fixed in the specification. That is, at least one instance and / or predefined pattern of two or more instances is configured by Radio Resource Control (RRC) signaling received from the wireless communication network by the communication device. Alternatively (or additionally), at least one instance and / or predefined pattern of two or more instances is indicated in the downlink control information (DCI) received by the communication device from the wireless communication network, which indicates that the sequence of instances of uplink communication resources of the radio access interface is active and can be used by the communication device to signal to the wireless communication network. Alternatively (or additionally), at least one instance and / or predefined pattern of two or more instances is predetermined and known to the communication device and infrastructure equipment.
[0158] Figure 24 Partial schematic flowchart representations and partial message flowchart representations of a wireless communication network including communication device 241 and infrastructure device 242 according to at least some embodiments of the present technology are shown. Communication device 241 is configured to transmit data to or receive data from the wireless communication network via a wireless access interface provided by the wireless communication network, for example, to or from infrastructure device 242. Specifically, communication device 242 may be configured to transmit data (e.g., Ultra-Reliable Low-Latency Communication (URLLC) data) to the wireless communication network (e.g., to infrastructure device 242) via the wireless access interface. Communication device 241 and infrastructure device 242 each include transceivers (or transceiver circuits) 241.1, 242.1 and controllers (or controller circuits) 241.2, 242.2. Each controller in controllers 241.2, 242.2 may be, for example, a microprocessor, CPU, or dedicated chipset.
[0159] like Figure 24As shown in the example, the transceiver circuitry 241.1 and controller circuitry 241.2 of communication device 241 are combined and configured to operate 243 according to a configured licensed (CG) operation mode, which includes communication device 241 configured to determine 244 (e.g., via an activation indication or other such command received from a wireless communication network, such as from infrastructure device 242) a sequence of instances of uplink communication resources of a wireless access interface, and to transmit 245 signals to the wireless communication network (e.g., infrastructure device 242) in at least one instance of the sequence of instances of uplink communication resources of the wireless access interface. The communication device 241 is configured to transmit uplink data 246 to a wireless communication network (e.g., from infrastructure device 242) in two or more instances of an instance sequence of uplink communication resources of the wireless access interface, as multiple repetitions of uplink data (where each instance may contain one or more repetitions of the same PUSCH), and to transmit one or more versions of uplink control information CG-UCI 247 to the wireless communication network (e.g., from infrastructure device 242), each version of CG-UCI associated with multiple instances of the instance sequence of uplink communication resources of the wireless access interface. Here, the communication device 241 is configured to transmit uplink data 246 and 247 and CG-UCI such that one or more versions of CG-UCI are each transmitted as two or more separate parts 247, each of the two or more parts being transmitted 247 in different instances of the two or more instances during the transmission of uplink data 246.
[0160] Essentially, such as Figure 24 The example shown in this embodiment of the technique proposes that the PUSCH can be repeated multiple times consecutively within a longer set of PUSCH repetitions. By reducing the number of bits within the CG-UCI by including portions of the CG-UCI at different positions within the repetitions, the code rate of the CG-UCI is reduced, and the reliability of the CG-UCI encoding can then be increased within the number of consecutive repetitions.
[0161] In this embodiment of the technology, when the application is repeated (or more specifically, when the application is repeated more than a threshold number of times), the CG-UCI can be subdivided (or divided into parts, or segments) and emitted within individual PUSCH repetitions. Therefore, the subdivided CG-UCI is a compact UCI compared to the original CG-UCI.
[0162] In the example, the CG-UCI consists of {HPN, RV, NDI, COT shared information}. At lower PUSCH repetition counts, these information fields are transmitted within a single CG-UCI and a single PUSCH. At higher repetition counts (e.g., when the PUSCH repetition count exceeds a threshold), the information bits are split into two CG-UCIs:
[0163] ·CG-UCI 1={HPN,RV}; and
[0164] ·CG-UCI 2 = {NDI, COT shared information}.
[0165] Then, separate CG-UCIs are transmitted in different PUSCH repetitions. Figure 25 An example is shown (it should be noted here that, for ease of understanding, the time range of CG-UCI is within...). Figure 25 (The extent of the exaggeration is unknown). Figure 25 The following is shown:
[0166] In the traditional case, each PUSCH repeatedly contains the CG-UCI, which contains a complete set of uplink control information ({HPN, RV, NDI, COT shared information}).
[0167] According to, as per the above Figure 24 In the above arrangement of the embodiments of the present technology described herein, half of the CG-UCI information is transmitted within one PUSCH repeat, and half of the CG-UCI information is transmitted within another PUSCH repeat:
[0168] • Time slot A—Transmits CG-UCI1 and signals {HPN, RV}. This information applies to both time slots A and B. HPN and RV are required for decoding the PUSCH, therefore preferably, these fields are transmitted within CG-UCI1 rather than CG-UCI2;
[0169] • Time slot B — Transmits CG-UCI2 and signals {NDI, COT shared information}.
[0170] • Time slot C—Similar to time slot A, but this information applies to both time slots C and D. It should be noted that the uplink control information transmitted in time slot C may differ from the uplink control information transmitted in time slot A; and
[0171] • Time slot D—similar to time slot B. Note that the uplink control information transmitted in time slot D may differ from the uplink control information transmitted in time slot B.
[0172] Those skilled in the art will understand that, since the number of information bits per CG-UCI has been reduced while the number of physical bits used to transmit the CG-UCI remains unchanged, the reliability of the uplink control information (i.e., CG-UCI1, which contains half the number of information bits of CG-UCI, has no retransmissions, and is expected to have the same / similar reliability as CG-UCI with two repetitions. In both cases, the effective code rate is the same) is increased.
[0173] It should be understood that, regarding such matters... Figure 24 and Figure 25 In the embodiments of the described technology, different aspects of CG-UCI can be updated / changed at different times. For example, RV can be updated in time slot A or time slot C, while COT shared information can be updated in time slot B or time slot D.
[0174] Those skilled in the art will understand that, as regarding Figure 24 and Figure 25 The operation of the described UE (or communication device) can be related to, for example, the operation of ... Figures 17 to 23 The described UE operations are combined; that is, the UE can transmit a repeated portion of the CG-UCI within a PUSCH repeat that includes uplink data. Those skilled in the art will understand that the disclosure herein relates to... Figures 17 to 23 The described embodiments or by means of Figure 24 and Figure 25 Any embodiment or example of the described embodiments can be combined with any other embodiment or example.
[0175] Although the above-described arrangement of embodiments of this technology has demonstrated how the reliability of the CG-UCI can be increased when repeating the PUSCH through segmentation of the CG-UCI, the UE needs to know that the boundary of the new CG-UCI should be within the PUSCH repetition. It is recommended that the first segment of the CG-UCI be transmitted with a known PUSCH repetition or in a predefined order. In other words, different instances of two or more instances containing two or more separate segments are known to the wireless communication network. Alternatively (or additionally), the two or more separate segments are transmitted within different instances of the two or more instances according to a predefined pattern known to the wireless communication network.
[0176] For example, an implementation of the known PUSCH repeat or predefined order is to transmit CG-UCI1 in the first PUSCH repeat and CG-UCI2 in the second PUSCH repeat. The third PUSCH repeat contains CG-UCI1, where this CG-UCI1 may have different content than the CG-UCI1 in the first PUSCH repeat, and the fourth repeat contains CG-UCI2, where this CG-UCI2 may have different content than the CG-UCI2 in the second PUSCH repeat. An example of a predefined order is that odd-numbered PUSCH repeats carry CG-UCI1, and odd-numbered PUSCH repeats carry CG-UCI2.
[0177] The predefined sequence or known PUSCH repetition of the repeating CG-UCI can be configured by RRC, signaled in the active DCI, or fixed in the specification. That is, different instances and / or predefined patterns of two or more instances are configured by Radio Resource Control (RRC) signaling received from the wireless communication network by the communication device. Alternatively (or additionally), the different instances and / or predefined patterns in the two or more instances are indicated in the downlink control information (DCI) received by the communication device from the wireless communication network, which indicates that the sequence of instances of uplink communication resources of the radio access interface is active and can be used by the communication device to signal to the wireless communication network. Alternatively (or additionally), the different instances and / or predefined patterns in the two or more instances are predetermined and known by the communication device and infrastructure equipment.
