Description

Technical Field

[0001] This invention relates to a communication apparatus for a wireless communication system, and more particularly to an apparatus for processing physical link shared channel transmission. Background Technology

[0002] The 3rd Generation Partnership Project (3GPP) developed the Long Term Evolution (LTE) system to improve the Universal Mobile Telecommunications System (UMTS), offering enhanced performance. LTE supports 3GPP Release 8 (Release 8) and / or 3GPP Release 9 (Release 9) standards to meet increasing user demands. LTE includes a new radio interface and wireless network architecture that provides high data rates, low latency, packet optimization, and improved system capacity and coverage.

[0003] The LTE-Advanced (LTE-A) system evolved from the LTE system. The goal of the LTE-Advanced system is to provide rapid power state transitions, improve edge performance of evolved Node-B (eNB), and increase peak data rates and throughput. It includes advanced technologies such as carrier aggregation, coordinated multipoint (CoMP) transmit / receive, uplink (UL) multiple-input multiple-output (UL MIMO), and licensed-assisted access (LAA) using LTE.

[0004] Next-generation radio access networks (NG-RAN) are developed to enhance Advanced Long Term Evolution (LTE) systems. NG-RAN comprises one or more next-generation nodes (gNBs) and features such as wider operating frequency bands, different parameter sets (numerologies) across different frequency ranges, massively multi-input multi-output (MIMO) systems, and advanced channel coding.

[0005] Due to limited uplink resources, user equipment (UE) struggles to efficiently perform uplink transmissions to next-generation base stations. Various procedures have been designed in different versions of the 3GPP standard to improve uplink transmission. This invention proposes multiple durations to provide a new architecture for uplink transmission, further enhancing efficiency. Summary of the Invention

[0006] Therefore, the present invention provides a communication device for processing physical link shared channel transmission to solve the above-mentioned problems.

[0030] Figure 1 This is a schematic diagram of a wireless communication system 10 according to an embodiment of the present invention, which is simply composed of a network terminal and multiple communication devices. The wireless communication system 10 can support time-division duplexing (TDD) mode, frequency-division duplexing (FDD) mode, a combined TDD and FDD mode, a non-terrestrial network (NTN) mode, or a licensed-assisted access (LAA) mode. That is, the network terminal and communication devices can communicate with each other through FDD carriers, licensed carriers (licensed service cells), and / or unlicensed carriers (or licensed service cells). Furthermore, the wireless communication system 10 can support carrier aggregation, that is, the network terminal and communication devices can communicate with each other through multiple service cells (e.g., multiple service carriers) that include a primary cell (e.g., a primary component carrier) and one or more secondary cells (e.g., secondary component carriers).

[0031] exist Figure 1In this document, the network end and communication device are used to illustrate the architecture of the wireless communication system 10. In a Universal Mobile Telecommunications System (UMTS), the network end may be a Universal Terrestrial Radio Access Network (UTRAN), which includes at least one base station (Node-B, NB). In one embodiment, in systems such as Long Term Evolution (LTE), LTE-advanced (LTE-A), and evolved versions of LTE, the network end may be an evolved universal terrestrial radio access network (E-UTRAN), which includes at least one evolved NB (eNB) and / or at least one relay station. In one embodiment, the network end may be a next-generation radio access network (NG-RAN) comprising at least one next-generation node-B (gNB) and / or at least one fifth-generation (5G) base station (BS). In another embodiment, the network end may be any base station conforming to a specific communication standard for communicating with the communication device.

[0032] New Radio (NR) is a standard defined for fifth-generation systems (or fifth-generation networks) to provide a unified air interface with improved performance. It deploys next-generation base stations to enable fifth-generation systems, supporting advanced features such as enhanced Mobile Broadband (eMBB), Ultra Reliable Low Latency Communications (URLLC), and massive Machine Type Communications (mMTC). EMBB provides broadband services with greater bandwidth and low / medium latency. URLLC provides higher reliability and low latency for applications such as end-to-end communication. Examples of such applications include industrial internet, smart grids, infrastructure protection, remote surgery, and intelligent transportation systems (ITS). MMTC enables the Internet of Things (IoT) of fifth-generation systems, which includes billions of connected devices and / or sensors.

[0033] In addition, the network end may include at least one of a Universal Terrestrial Global Access Network (UTC), an Evolved Universal Terrestrial Global Access Network (EPG), a Next Generation Radio Access Network (NGR), and a core network. The core network includes network entities such as a Mobility Management Entity (MME), a Serving Gateway (S-GW), a Packet Data Network (PDN) Gateway (P-GW), a Self-Organizing Networks (SON) server, and / or a Radio Network Controller (RNC). In one embodiment, after receiving information transmitted by a communication device at the network end, the information may only be processed by the UTC, Evolved Universal Terrestrial Global Access Network (EPG), or Next Generation Radio Access Network, and a decision corresponding to the information may be made within the UTC, Evolved Universal Terrestrial Global Access Network (EPG), or Next Generation Radio Access Network. In one embodiment, the Universal Terrestrial Global Access Network (UTC) / Evolved Universal Terrestrial Global Access Network (ETHG) / Next Generation Global Access Network (NGG) can forward information to a core network. After processing the information, the core network makes a decision corresponding to the information. In one embodiment, the information can be processed by the UTC / ETHG / NGG and the core network, and decisions can be made after coordination and / or cooperation between the UTC / ETHG / NGG and the core network.

[0034] The communication device can be user equipment (UE), a low-cost device (e.g., a machine-type communication (MTC) device), a device-to-device (D2D) communication device, a narrow-band Internet of Things (NB-IoT) device, a mobile phone, a laptop computer, a tablet computer, an e-reader, a portable computer system, or a combination of the above. Furthermore, depending on the transmission direction, the network end and the communication device can be considered as the transmitting end or the receiving end, respectively. For example, for an uplink (UL), the communication device is the transmitting end and the network end is the receiving end; for a downlink (DL), the network end is the transmitting end and the communication device is the receiving end.

[0035] Figure 2 This is a schematic diagram of a communication device 20 according to Embodiment 1 of the present invention. The communication device 20 may be... Figure 1 The communication device 20 may include, but is not limited to, a communication device or network terminal. The communication device 20 may include at least one processing circuit 200, at least one storage device 210, and at least one communication interface device 220. The at least one processing circuit 200 may be a microprocessor or an application-specific integrated circuit (ASIC). The at least one storage device 210 may be any data storage device used to store program code 214, and the at least one processing circuit 200 can read and execute the program code 214 through the at least one storage device 210. For example, at least one storage device 210 may be a Subscriber Identity Module (SIM), Read-Only Memory (ROM), Flash Memory, Random-Access Memory (RAM), Compact Disc ROM (CD-ROM), Digital Versatile Disc-ROM (DVD-ROM), Blu-ray Disc-ROM (BD-ROM), Magnetic Tape, Hard Disk, Optical Data Storage Device, Non-volatile Storage Device, Non-transitory Computer-readable Medium (e.g., tangible media), etc., and is not limited thereto. At least one communication interface device 220 may include at least one wireless transceiver, which is used to transmit and receive signals (e.g., data, information, and / or packets) based on the processing results of at least one processing circuit 200.

[0036] Figure 3 This is a flowchart of process 30 according to Embodiment 1 of the present invention. Process 30 is used for... Figure 1 A communication device for handling physical uplink shared channel transmissions. Process 30 can be compiled into program code 214, which includes the following steps:

[0037] Step 300: Begin.

[0038] Step 302: Receive an indicator from a network end indicating repetition of the physical UL shared channel (PUSCH) among multiple entities.

[0039] Step 304: Determine at least one nominal transmission duration for repetition on the shared channel of the multiple entities.

[0040] Step 307: According to the indicator, during the at least one nominal transmission duration, the multiple entities uplink shared channel is repeatedly transmitted to the network end.

[0041] Step 308: End.

[0042] According to procedure 30, the communication device receives an indicator from the network end indicating the repetition of multiple entity uplink shared channels. The communication device determines at least one nominal transmission duration for the repetition of multiple entity uplink shared channels. Then, according to the indicator, the communication device transmits the repetition of multiple entity uplink shared channels to the network end within at least one nominal transmission duration. That is, at least one nominal transmission duration is determined to provide a new transmission duration for transmitting the repetition of entity uplink shared channels. Therefore, the repetition of entity uplink shared channels can be correctly received by the network end.

[0043] There are many ways to implement process 30, not limited to those described above. The following examples can be used for process 30.

[0044] In one embodiment, the repetition of multiple entity uplink shared channels belongs to a single-layer transmission. In one embodiment, the repetition of multiple entity uplink shared channels is a transport block (TB) (e.g., a time slot) on multiple time slots. In one embodiment, the repetition of multiple entity uplink shared channels is in different time slots. In one embodiment, at least two repetitions (e.g., 2, 3, 4, etc.) of the repetition of multiple entity uplink shared channels are in the same time slot.

[0045] In one embodiment, the communication device further transmits a capability related to a determination of at least one nominal transmission duration to the network end. For example, the capability includes the maximum time gap between two uplink transmissions (e.g., a physical uplink shared channel), the maximum total time gap between all uplink transmissions (e.g., a physical uplink shared channel) during the nominal transmission duration, the total number of time gaps during the nominal transmission duration, and / or the demodulation order of the uplink transmission. Therefore, when the communication device is instructed to perform an uplink transmission during the nominal transmission duration, performing channel estimation for the uplink transmission (e.g., a physical uplink shared channel) requires fewer demodulation reference signals (DMRS). In one embodiment, the number of demodulation reference signals during the nominal transmission duration can be determined based on the demodulation order of the uplink transmission. In one embodiment, the location of the demodulation reference signals during the nominal transmission duration can be a fixed location or can be determined based on instructions transmitted by the network end (e.g., uplink allowance or higher-level configuration). In one embodiment, the capability includes the maximum duration of power consistency and phase continuity maintained by the communication device, enabling the communication device to support demodulation reference signal bundling for the physical uplink shared channel and / or physical uplink control channel (PUCCH).

[0046] In one embodiment, the length of the nominal transmission duration of at least one nominal transmission duration is determined according to a higher-level configuration, and the nominal transmission duration of at least one nominal transmission duration includes a plurality of consecutive time slots. In one embodiment, the minimum length of the nominal transmission duration of at least one nominal transmission duration is 2 time slots.

[0047] In one embodiment, the length of the last nominal transmission duration of at least one nominal transmission duration is determined by the communication device (or network end). In one embodiment, at least one nominal transmission duration is respectively set for at least one bandwidth part (BWP).

[0048] In one embodiment, the start of at least one nominal transmission duration is the start symbol of the repetition of multiple entity uplink shared channels. In another embodiment, the end of at least one nominal transmission duration is the last symbol of the repetition of multiple entity uplink shared channels.

[0049] In one embodiment, the nominal transmission duration of at least one nominal transmission duration includes at least one of the actual transmission duration and the event. The actual transmission duration may include one or more demodulation reference signals. In one embodiment, the start of the actual transmission duration is the start symbol of the first instance of the multiple entity uplink shared channel repetitions within the nominal transmission duration of at least one nominal transmission duration. In one embodiment, the end of the actual transmission duration is the last symbol of the last instance of the multiple entity uplink shared channel repetitions before the event. In one embodiment, the start of the actual transmission duration is the start symbol of the first instance of the multiple entity uplink shared channel repetitions after the event. In one embodiment, the end of the actual transmission duration is the last symbol of the last instance of the multiple entity uplink shared channel repetitions. Therefore, multiple time durations are used to perform entity uplink shared channel repetitions.

[0050] In one embodiment, the event causes (e.g., before and after the event) at least one of the power consistency and phase continuity of two entity uplink shared channel repetitions spanning multiple entity uplink shared channel repetitions to be lost. In one embodiment, the event includes a gap length greater than a threshold between the two entity uplink shared channel repetitions. In one embodiment, there is no actual transmission duration after the event. That is, the communication device may not resume entity uplink shared channel repetitions after the event. In one embodiment, the event includes (e.g., performed by the communication device or network end) the cancellation of entity uplink shared channel repetitions of multiple entity uplink shared channel repetitions. In one embodiment, the cancellation is determined based on downlink control information (DCI) transmitted by the network end. In one embodiment, the cancellation is caused by different transmission directions, such as a conflict between uplink transmission and downlink reception. Since power consistency and phase continuity cannot be maintained, the communication device may transmit at least one demodulation reference signal during the actual transmission duration after the event.

[0051] In one embodiment, the indicator is obtained based on downlink control information transmitted by the network. In another embodiment, the indicator is obtained based on a set allowance configuration transmitted by the network.

[0052] If the communication device can maintain power consistency and phase continuity over a given period, it can transmit more physical uplink shared channels while transmitting fewer demodulation reference signals (e.g., the number of demodulation reference signals is less than the number of physical uplink shared channels). The resources saved by not transmitting demodulation reference signals can be used to transmit physical uplink shared channels, improving their transmission efficiency. Correspondingly, by using fewer demodulation reference signals, the network can perform advanced reception techniques (e.g., joint channel estimation) to receive physical uplink shared channels during the duration. If an event occurs during the duration, the communication device may not maintain power consistency and phase continuity during that duration. An event may include at least one of the following: a change in modulation order; a change in resource block (RB) allocation based on the length and frequency location of the resource block; a change in the transmission power level of the service cell at the network end of the communication device; an uplink beam switching of the communication device (e.g., a user terminal of frequency range 2 (FR2)); more than X un-scheduled orthogonal frequency division multiplexing (OFDM) symbols in the physical uplink shared channel or physical uplink control channel; and a downlink reception occurring in the physical uplink shared channel or physical uplink control channel.

[0053] Figure 4 This is a schematic diagram of the transmission area according to an embodiment of the present invention. Figure 4 Four scenarios are considered. In scenario 1, two transmission areas TB0 and TB1 are transmitted or scheduled in time slots SL0-SL5. Transmission area TB0 is transmitted in time slots SL0-SL2, and transmission area TB1 is transmitted in time slots SL3-SL5. The length of the transmission area is the same as the length of the time slot. In scenario 2, transmission areas TB0 and TB1 are the same transmission area. That is, transmission area TB0 is transmitted or scheduled in time slots SL0-SL5. The length of the transmission area is the same as the length of the time slot. In scenario 3, transmission area TB0 is transmitted or scheduled in time slots SL0-SL5. The length of the transmission area is the same as the length of five time slots. In scenario 4, four transmission areas TB0-TB3 are transmitted or scheduled in time slot SL0. In one embodiment, transmission areas TB0-TB3 are the same transmission area. In one embodiment, the length of the time slot is the same as or not less than the length of four transmission areas. It should be noted that the transmission area in the above case is transmitted in the physical link shared channel.

[0054] Figure 5This is a schematic diagram illustrating the transmission of physical uplink shared channel repetitions according to an embodiment of the present invention. In this embodiment, the actual transmission duration includes eight physical uplink shared channel repetitions PSH0 to PSH7. The length of each physical uplink shared channel repetition is the same as the length of the time slot. The nominal transmission duration includes four physical uplink shared channel repetitions. Therefore, in this embodiment, the actual transmission duration includes two nominal transmission durations. That is, multiple durations are provided to the communication device to transmit physical uplink shared channel repetitions PSH0 to PSH7. The length of the nominal transmission duration is determined based on at least one of the following: higher-layer signals (e.g., radio resource control (RRC) signals and / or medium access control (MAC) signals), physical layer signals (e.g., downlink control signals), modulation order (e.g., binary phase-shift keying (BPSK), quadrature phase-shift keying (QPSK), or 16 quadrature amplitude modulation (16-QAM)), and sub-carrier spacing. The communication device can receive uplink allowance downlink control information. The uplink allowance downlink control information indicates the resources used for repeating PSH0 to PSH7 on the uplink shared channel of the transmission entity, and indicates the length of the nominal transmission duration (e.g., 4 time slots).

[0055] Figure 6 This is a schematic diagram illustrating repeated transmissions on the shared uplink channel in an embodiment of the present invention. The communication device can be configured with an uplink / downlink setting indicating the transmission direction of the time slot. Figure 6 In this embodiment, the nominal transmission duration NTD0 includes three time slots ST0 to ST2: an uplink time slot, a flexible time slot, and an uplink time slot, respectively. Time slot ST0 includes physical uplink shared channel repetitions PSH0 and PSH1. Time slot ST1 includes events, and physical uplink shared channel repetitions in time slot ST1 are ignored (e.g., dropped or canceled). Time slot ST2 includes physical uplink shared channel repetitions PSH2 and PSH3. Time slots ST0 and ST2 can be considered as the actual transmission durations ATD0 and ATD1 of the physical uplink shared channel repetitions PSH0 to PSH3. Therefore, in this embodiment, the nominal transmission duration includes two actual transmission durations.

[0056] The actual transmission duration ATD0 begins with the start symbol of the physical uplink shared channel repetition PSH0 (i.e., the start of the physical uplink shared channel repetition within the actual transmission duration ATD0). The actual transmission duration ATD0 may include at least one demodulation reference signal, such as the start symbol of the physical uplink shared channel repetition PSH0. The actual transmission duration ATD0 ends with the last symbol of the physical uplink shared channel repetition PSH1 (i.e., the last physical uplink shared channel repetition before the event). Examples of events are described above and will not be repeated here.

[0057] The actual transmission duration ATD2 begins with the start symbol of the entity uplink shared channel repetition PSH2 (i.e., the start of the entity uplink shared channel repetition after the event). The actual transmission duration ATD2 may contain at least one demodulation reference signal, such as the start symbol of the entity uplink shared channel repetition PSH2. That is, after the event, at least one demodulation reference signal for the relevant entity uplink shared channel is immediately transmitted. The actual transmission duration ATD2 ends with the last symbol of the entity uplink shared channel repetition PSH3 (i.e., the last entity uplink shared channel repetition).

[0058] In one embodiment, if the length of an event is less than a certain value (e.g., X symbols), the communication device may not transmit any demodulation reference signal during the actual transmission duration ATD2, for example, because power consistency and phase continuity do not change much.

[0059] In one embodiment, if the length of the event is greater than a first value (e.g., X symbols) and the length of the actual transmission duration ATD2 is less than a second value (e.g., Y symbols or Y repetitions), the communication device may not transmit any entity uplink shared channel repetitions during the actual transmission duration ATD2.

[0060] In one embodiment, if the length of the event is greater than a first value (e.g., X symbols) and the length of the actual transmission duration ATD2 is greater than a second value (e.g., Y symbols or Y repetitions), the communication device may transmit at least one entity uplink shared channel repetition during the actual transmission duration ATD2.
