Description

[Technical field]

[0001] The present disclosure relates generally to wireless communication systems, and more specifically, to supporting channel state information (CSI) feedback from a user equipment (UE) to a serving base station for support of multiple services. [Background technology]

[0002] Efforts are being made to develop improved 5G or pre-5G communication systems to meet the increasing demand for wireless data traffic since the commercialization of the 4th generation (4G) communication system. For this reason, 5G or pre-5G communication systems are further called "Beyond 4G Network" or "Post LTE" communication systems. To achieve high data rates, 5G communication systems are expected to be implemented in ultra-high frequency (mmWave) bands (e.g., 60 GHz bands). To reduce radio wave propagation loss and increase transmission distances, beamforming, multiple-input multiple-output (MIMO), full dimensional MIMO, array antennas, analog beam-forming, and large scale antenna technologies are being discussed for 5G communication systems. Furthermore, to improve the system network, technologies being developed for the 5G communication system include advanced small cell, cloud Radio Access Network (cloud RAN), ultra-dense network, Device-to-Device (D2D) communication, wireless backhaul, moving network, cooperative communication, CoMP (Coordinated Multi-Points), and reception-end interference cancellation.For 5G communication systems, advanced coding modulation (ACM) methods such as FQAM (Hybrid FSK and QAM Modulation) and SWSC (Sliding Window Superposition Coding) and advanced access technologies such as FBMC (Filter Bank Multi Carrier), NOMA (non-orthogonal multiple access), and SCMA (sparse code multiple access) are being developed.

[0003] The Internet, a human-centered network where humans generate and consume information, is evolving into the Internet of Things (IoT), where distributed entities such as things exchange and process information without human intervention. The Internet of Everything (IoE) technology, which combines IoT technology and big data processing technology through connection to cloud servers, is emerging. To realize IoT, technological elements such as sensing technology, wired and wireless communication and network infrastructure, service interface technology, and security technology are required, and recently, technologies such as sensor networks, M2M (Machine to Machine), and MTC (Machine Type Communication) for connecting things are being researched. In the IoT environment, intelligent IT (Internet Technology) services can be provided that collect and analyze data generated by connected things to create new value in human life. IoT can be applied to fields such as smart homes, smart buildings, smart cities, smart cars or connected cars, smart grids, healthcare, smart home appliances, and advanced medical services through the convergence and integration of existing IT (information technology) technologies and various industries.

[0004] As a result, various attempts are being made to apply 5G communication systems to IoT networks. For example, technologies such as sensor networks, MTC (Machine Type Communication), and M2M (Machine to Machine) are being embodied in 5G communication technologies using techniques such as beamforming, MIMO, and array antennas. The application of cloud Radio Access Network (Cloud RAN) as the aforementioned big data processing technology is also an example of the convergence between 5G and IoT technologies.

[0018] The following Figures 1 to 3 illustrate various embodiments implemented using orthogonal frequency division multiplexing (OFDM) or orthogonal frequency division multiple access (OFDMA) communication technology in a wireless communication system. The descriptions of Figures 1 to 3 do not imply physical or architectural limitations on the manner in which different embodiments may be implemented. The different embodiments of the present disclosure may be implemented in any appropriately arranged communication system.

[0019] 1 illustrates an exemplary wireless network according to the present disclosure. The embodiment of the wireless network illustrated in FIG. 1 is for illustration purposes only. Other embodiments of the wireless network 100 may be used without departing from the scope of the present disclosure.

[0020] 1, the wireless network includes gNB101 (e.g., a base station (BS)), gNB102, and gNB103. gNB101 communicates with gNB102 and gNB103. gNB101 further communicates with at least one network 130, such as the Internet, a proprietary Internet Protocol (IP) network, or other data network.

[0021] The gNB 102 provides wireless broadband access to the network 130 for a first plurality of UEs within the coverage area 120 of the gNB 102. The first plurality of UEs includes UE 111, which may be located at a small business (SB); UE 112, which may be located at an enterprise (E); UE 113, which may be located at a WiFi hotspot (HS); UE 114, which may be located at a first residence (R); UE 115, which may be located at a second residence (R); and UE 116, which may be a mobile device (M) such as a cell phone, a wireless laptop, a wireless PDA, etc. The gNB 103 provides wireless broadband access to the network 130 for a second plurality of UEs within the coverage area 125 of the gNB 103. The second plurality of UEs includes UE 115 and UE 116. In some embodiments, one or more of the gNBs 101-103 may communicate with each other and with the UEs 111-116 using 5G, LTE, LTE-A, WiMAX, WiFi, or other wireless communication technologies. In some embodiments, one or more of the gNBs 101-103 may communicate with each other and with the UEs 111-116 using 5G / NR, LTE, LTE-A, WiMAX, WiFi, or other wireless communication technologies.

[0022] Depending on the network type, the term "base station" or "BS" may refer to any component (or collection of components) configured to provide wireless access to a network, such as a transmit point (TP), transmit-receive point (TRP), enhanced base station (eNodeB or eNB), 5G base station (gNB), macrocell, femtocell, WiFi access point (AP), or other wirelessly enabled device. A base station may provide wireless access via one or more wireless communication protocols, such as 5G 3GPP new radio interface / access (NR), long term evolution (LTE), LTE-advanced (LTE-A), high speed packet access (HSPA), Wi-Fi 802.11a / b / g / n / ac, etc. For convenience, the terms "BS" and "TRP" are used in this patent document to refer to network infrastructure components that provide wireless access to a remote terminal. Furthermore, depending on the network type, the term "user equipment" or "UE" can refer to any component such as a "mobile station," "subscriber station," "remote terminal," "wireless terminal," "receive point," or "user device."For convenience, the terms "user equipment" and "UE" are used in this patent document to refer to a remote wireless device that wirelessly accesses a BS, whether a UE is considered to be a mobile device (such as a mobile phone or smartphone) or generally a stationary device (such as a desktop computer or vending machine).

[0023] The dotted lines indicate the approximate extents of coverage areas 120 and 125, which are shown largely in outline for purposes of illustration and explanation only. It should be clearly understood that coverage areas associated with gNBs, such as coverage areas 120 and 125, can have other shapes, including irregular shapes, depending on the configuration of the gNBs and changes in the radio environment due to natural and man-made obstructions.

[0024] As described in more detail below, one or more of the UEs 111-116 include circuitry, programming, or a combination thereof for efficient CSI reporting for multiple services in the new wireless system. In particular embodiments, one or more of the gNBs 101-103 include circuitry, programming, or a combination thereof for efficient CSI reporting for multiple services in the new wireless system.

[0025] Although FIG. 1 illustrates an example of wireless network 100, various modifications to FIG. 1 may be made. For example, wireless network 100 may include any number of gNBs and any number of UEs in any suitable arrangement. Additionally, gNB 101 may directly communicate with any number of UEs and provide such UEs with wireless broadband access to network 130. Similarly, each gNB 102-103 may directly communicate with network 130 and provide UEs with direct wireless broadband access to the network. Additionally, gNBs (101, 102, and / or 103) may provide access to other or additional external networks, such as an external telephone network or other type of data network.

[0026] 2 illustrates an exemplary gNB 102 according to an embodiment of the present disclosure. The embodiment of gNB 102 illustrated in FIG. 2 is for illustration only, and gNBs 101 and 103 of FIG. 1 may have the same or similar configurations. However, gNBs have a variety of configurations, and FIG. 2 does not limit the scope of the present disclosure to any particular implementation of a gNB.

[0027] 2, the gNB 102 includes multiple antennas 205a-205n, multiple RF transceivers 210a-210n, transmit (TX) processing circuitry 215 and receive (RX) processing circuitry 220. The gNB 102 further includes a controller / processor 225, memory 230 and a backhaul and / or network interface 235.

[0028] The RF transceivers 210a-210n receive incoming RF signals from the antennas 205a-205n, such as signals transmitted by UEs in the network 100. The RF transceivers 210a-210n downconvert the incoming RF signals to generate IF or baseband signals. The IF or baseband signals are sent to RX processing circuitry 220, which generates processed baseband signals by filtering, decoding, and / or digitizing the baseband or IF signals. The RX processing circuitry 220 sends the processed baseband signals to the controller / processor 225 for further processing.

[0029] TX processing circuitry 215 receives analog or digital data (such as voice data, web data, email, or interactive video game data) from controller / processor 225. TX processing circuitry 215 encodes, multiplexes, and / or digitizes the outgoing baseband data to generate processed baseband or IF signals. RF transceivers 210a-210n receive the outgoing processed baseband or IF signals from TX processing circuitry 215 and upconvert the baseband or IF signals to RF signals that are transmitted via antennas 205a-205n.

[0030] The controller / processor 225 may include one or more processors or other processing devices that control the overall operation of the gNB 102. For example, the controller / processor 225 may control the reception of forward channel signals and the transmission of reverse channel signals by the RF transceivers 210a-210n, the RX processing circuitry 220, and the TX processing circuitry 215 according to well-known principles. The controller / processor 225 may further support additional functions, such as more advanced wireless communication functions. For example, the controller / processor 225 may support beamforming or directional routing operations in which transmitted signals from multiple antennas 205a-205n are weighted differently to effectively steer the transmitted signals in a desired direction. Any of a variety of other functions may be supported in the gNB 102 by the controller / processor 225.

[0031] The controller / processor 225 can also execute programs and other processes that reside in the memory 230, such as the operating system. The controller / processor 225 can move data in and out of the memory 230 as required by the executing processes.

[0032] The controller / processor 225 is further coupled to a backhaul or network interface 235. The backhaul or network interface 235 enables the gNB 102 to communicate with other devices or systems over a backhaul connection or network. The interface 235 can support communication over any suitable wired or wireless connection. For example, when the gNB 102 is embodied as part of a cellular communication system (such as supporting 5G, LTE, or LTE-A), the interface 235 enables the gNB 102 to communicate with other gNBs over a wired or wireless backhaul connection. When the gNB 102 is embodied as an access point, the interface 235 enables the gNB 102 to communicate to a wired or wireless local area network or a larger network (such as the Internet) over a wired or wireless connection. The interface 235 includes any suitable structure supporting communication over a wired or wireless connection, such as an Ethernet or RF transceiver.

[0033] The memory 230 is coupled to the controller / processor 225. A portion of the memory 230 may include RAM, and another portion of the memory 230 may include Flash memory or other ROM.

[0034] Although FIG. 2 illustrates an example of a gNB 102, various modifications to FIG. 2 may be made. For example, the gNB 102 may include any number of each of the components illustrated in FIG. 2. As a particular example, the access point may include multiple interfaces 235, and the controller / processor 225 may support a routing function that routes data between different network addresses. As another particular example, although shown as including a single instance of the TX processing circuitry 215 and a single instance of the RX processing circuitry 220, the gNB 102 may include multiple instances of each (such as one per RF transceiver). Additionally, various components of FIG. 2 may be combined, further subdivided, or omitted, and additional components may be added as needed.

[0035] Figure 3 illustrates an example UE 116 according to an embodiment of the present disclosure. The embodiment of the UE 116 illustrated in Figure 3 is for illustration purposes only, and the UEs 111-115 of Figure 1 may have the same or similar configuration. However, UEs have a variety of configurations, and Figure 3 does not limit the scope of the present disclosure to any particular implementation of a UE.

[0036] 3, the UE 116 includes an antenna 305, a radio frequency (RF) transceiver 310, a TX processing circuit 315, a microphone 320, and a receive (RX) processing circuit 325. The UE 116 further includes a speaker 330, a processor 340, an input / output (I / O) interface (IF) 345, a touchscreen 350, a display 355, and a memory 360. The memory 360 includes an operating system (OS) 361 and one or more applications 362.

[0037] The RF transceiver 310 receives an incoming RF signal transmitted by a gNB of the network 100 from the antenna 305. The RF transceiver 310 down-converts the incoming RF signal to generate an intermediate frequency (IF) or baseband signal. The IF or baseband signal is sent to the RX processing circuitry 325, which generates a processed baseband signal by filtering, decoding and / or digitizing the baseband or IF signal. The RX processing circuitry 325 sends the processed baseband signal to a speaker 330 (such as voice data) or a processor 340 for further processing (such as web browsing data).

[0038] TX processing circuitry 315 receives analog or digital voice data from microphone 320 or other outgoing baseband data (such as web data, email, or interactive video game data) from processor 340. TX processing circuitry 315 encodes, multiplexes, and / or digitizes the outgoing baseband data to generate a processed baseband or IF signal. RF transceiver 310 receives the outgoing processed baseband or IF signal from TX processing circuitry 315 and upconverts the baseband or IF signal to an RF signal that is transmitted via antenna 305.

[0039] Processor 340 may include one or more processors or other processing devices and may execute an OS 361 stored in memory 360 to control the overall operation of UE 116. For example, processor 340 may control the reception of forward channel signals and the transmission of reverse channel signals by RF transceiver 310, RX processing circuitry 325, and TX processing circuitry 315 in accordance with well-known principles. In some embodiments, processor 340 includes at least one microprocessor or microcontroller.

[0040] The processor 340 may also execute other processes and programs resident in the memory 360, such as processes for beam management. The processor 340 may move data in and out of the memory 360 as required by the executing processes. In some embodiments, the processor 340 may be configured to execute applications 362 based on the OS 361 or in response to signals received from the gNB or an operator. The processor 340 may further be coupled to an I / O interface 345 that provides the UE 116 with the ability to connect to other devices, such as laptop computers and handheld computers. The I / O interface 345 may be a communication path between such accessories and the processor 340.

[0041] Processor 340 is further coupled to a touchscreen 350 and a display 355. An operator of UE 116 can use touchscreen 350 to input data into UE 116. Display 355 can be a liquid crystal display, a light emitting diode display, or other display capable of rendering text and / or at least limited graphics, such as from a web site.

[0042] Memory 360 is coupled to processor 340. A portion of memory 360 may include random access memory (RAM), and another portion of memory 360 may include flash memory or other read-only memory (ROM).

[0043] Although FIG. 3 illustrates an example of a UE 116, various modifications to FIG. 3 may be made. For example, various components of FIG. 3 may be combined, further subdivided, or omitted, and additional components may be added as needed. As a specific example, the processor 340 may be divided into multiple processors, such as one or more central processing units (CPUs) and one or more graphics processing units (GPUs). Also, although FIG. 3 illustrates a UE 116 configured as a mobile phone or smartphone, the UE may be configured to operate as other types of mobile or fixed devices.

[0044] Efforts have been made to develop improved 5G / NR or pre-5G / NR communication systems to meet the increased demand for wireless data traffic since the commercialization of the 4G communication system. Therefore, the 5G / NR or pre-5G / NR communication systems are further referred to as "beyond 4G network" or "post LTE system" communication systems. The 5G / NR communication system is considered to be implemented in a higher frequency (mmWave) band, for example, the 60 GHz band, to achieve a higher data transmission rate, or in a lower frequency band such as 6 GHz to enable robust coverage and mobility support. In order to reduce the propagation loss of radio waves and increase the transmission distance, beamforming, multiple-input multiple-output (MIMO), full dimensional MIMO (FD-MIMO), array antennas, analog beamforming, and large-scale antenna technologies are being discussed for the 5G / NR communication system. In addition, in the 5G / NR communication system, developments are being carried out to improve the system network based on advanced small cells, cloud radio access networks (RANs), ultra-high density networks, device-to-device (D2D) communications, wireless backhaul, mobile networks, cooperative communications, coordinated multi-point (CoMP), and receiver-end interference cancellation.

[0045] A communication system includes a downlink (DL) which refers to transmission from a base station or one or more transmitting points to a UE, and an uplink (UL) which refers to transmission from the UE to a base station or one or more receiving points.

[0046] A time unit for DL ​​signaling or UL signaling on a cell is referred to as a slot and can include one or more symbols. A symbol can serve as an additional time unit. A frequency (or bandwidth (BW)) unit is referred to as a resource block (RB). One RB includes multiple subcarriers (SCs). For example, a slot can have a duration of 0.5 ms or 1 ms and can include 14 symbols, and an RB can include 12 SCs with an inter-SC spacing of 15 KHz or 30 KHz, etc. One RB over one symbol is referred to as a PRB (physical RB).

[0047] DL signals include data signals carrying information content, control signals carrying DL control information (DCI), and reference signals (RS), also known as pilot signals. The gNB transmits data information or DCI via a respective physical DL shared channel (PDSCH) or physical DL control channel (PDCCH). The PDSCH or PDCCH can be transmitted via various numbers of slot symbols, including one slot symbol. For simplicity, a DCI format for scheduling PDSCH reception by a UE is referred to as a DL DCI format, and a DCI format for scheduling PUSCH transmission from a UE is referred to as a ULDCI format.

[0048] The gNB transmits one or more of multiple types of RS, including channel state information RS (CSI-RS) and demodulation RS (DMRS). CSI-RS is mainly for UE to perform measurements and provide channel state information (CSI) to the gNB. For channel measurements, non-zero power CSI-RS (NZP CSI-RS) resources are used. For interference measurement reports (IMR), CSI interference measurement (CSI-IM) resources associated with zero power CSI-RS (ZP CSI-RS) configuration are used. The CSI process consists of NZP CSI-RS and CSI-IM resources.

[0049] The UE can determine CSI-RS transmission parameters via higher layer signaling, such as DL control signaling or Radio Resource Control (RRC) signaling, from the gNB. The transmission instance of the CSI-RS can be indicated by DL control signaling or can be configured by higher layer signaling. The DMRS is transmitted only in the BW of each PDCCH or PDSCH, and the UE can demodulate data or control information using the DMRS.

[0050] 4 illustrates an example DL slot structure 400 according to an embodiment of the present disclosure. The embodiment of DL slot structure 400 illustrated in FIG. 4 is for illustrative purposes only and may have the same or similar configurations. FIG. 4 does not limit the scope of the present disclosure to any particular implementation.

[0051] DL slot 410 allows the gNB to transmit data information, DCI or DMRS.

[0052] The UL signal further includes a data signal carrying information content, a control signal carrying UL control information (UCI), a DMRS associated with data or UCI demodulation, a sounding RS (SRS) that enables the gNB to perform UL channel measurements, and a random access (RA) preamble that enables the UE to perform random access. The UE transmits data information, which is further referred to as a transmission block or UL shared channel (UL-SCH), or UCI over a respective physical UL shared channel (PUSCH) or physical UL control channel (PUCCH). The PUSCH or PUCCH can be transmitted over a variable number of symbols in a slot containing one symbol.

[0053] The UCI includes hybrid automatic repeat request acknowledgement (HARQ-ACK) information indicating correct or incorrect detection of a data transmission block (TB) in the PDSCH, a scheduling request (SR) indicating whether the UE has data in the UE's buffer, and a CSI report that enables the gNB to select appropriate parameters for PDSCH or PDCCH transmission to the UE. The HARQ-ACK information may have a granularity smaller than every TB and may be for each code block (CB) or group of CBs, where a TB includes a number of CBs. If PDSCH reception providing the TB is scheduled by a DCI format, the DCI format may include a field indicating a slot for PUCH transmission and a PUCCH resource for PUCCH transmission together with HARQ-ACK information in response to TB reception. If parameters for PDSCH reception providing the TB are provided by a higher layer, the higher layer may further provide a slot for PUCH transmission and a PUCCH resource for PUCCH transmission together with HARQ-ACK information in response to TB reception.

[0054] When a first PUCCH transmission including a first UCI (HARQ-ACK information, or SR, or CSI report) from a UE in a slot overlaps in time with a second PUCCH transmission including a second UCI in the slot, the UE may determine a new PUCCH resource for multiplexing the first UCI type and the second UCI type in a third PUCCH transmission in the slot, the multiplexing being subject to a predetermined timeline being shifted.

[0055] The CSI report from the UE may include a channel quality indicator (CQI) that informs the gNB of a maximum modulation and coding scheme (MCS) for detecting a TB with a predetermined block error rate (BLER) such as 10% by the UE providing an index to an MCS table, a precoding matrix indicator (PMI) that informs the gNB of how to combine signals from multiple transmitter antennas according to the multiple input multiple output (MIMO) transmission principle, and a rank indicator (RI) that indicates the transmission rank for the PDSCH. The CSI report may further include a CSI-RS resource indicator (CRI) that indicates a CSI-RS resource used for measuring the CSI report.

[0056] UL RS includes DMRS and SRS. DMRS is transmitted only in the BW of the respective PUSCH or PUCCH transmission. The gNB can demodulate the information in the respective PUSCH or PUCCH using the DMRS. SRS is transmitted by the UE to provide UL CSI to the gNB, and in the case of a TDD system, the SRS transmission can further provide PMI for DL ​​transmission. Additionally, the UE can transmit a physical random access channel (PRACH) to synchronize with the gNB or set up an initial upper layer connection.

[0057] When a UE simultaneously transmits data information on a PUSCH and UCI on a PUCCH, if a set of predetermined timeline conditions is satisfied such that the UE can cancel PUCCH transmission and multiplex HARQ-ACK information or CSI on the PUSCH transmission, the UE can multiplex both TB and UCI for the UL-SCH on the PUSCH. Similarly, as described above, when a UE simultaneously transmits a first PUCCH and a second PUCCH, if a set of predetermined timeline conditions is satisfied such that the UE can cancel the first and second PUCCH transmissions and multiplex corresponding UCI on the third PUCCH transmission, the UE can multiplex all corresponding UCI on the third PUCCH.

The embodiment of the UL slot structure 500 illustrated in FIG. 5 is for illustrative purposes only and may have the same or similar configuration. FIG. 5 does not limit the scope of the present disclosure to any particular implementation.

[0059] As shown in FIG. 5, slot 510 is where the UE transmits data information, UCI or DMRS.

[0060] DL and UL transmissions can be based on orthogonal frequency division multiplexing (OFDM) waveforms, including a variant that uses DFT precoding known as DFT-spread-OFDM.

[0061] 6 and 7 illustrate example wireless transmit and receive paths according to the present disclosure. In the following description, the transmit path 600 may be described as being implemented in a gNB (e.g., gNB 102), while the receive path 700 may be described as being implemented in a UE (e.g., UE 116). However, it is understood that the receive path 700 may be implemented in a gNB and the transmit path 600 may be implemented in a UE. In some embodiments, the receive path 700 is configured to support codebook design and construction for a system with a 2D antenna array as described in embodiments of the present disclosure.

[0062] The transmit path 600 includes a channel coding and modulation block 605, a serial-to-parallel (S-to-P) block 610, a size-N inverse fast Fourier transform (IFFT) block 615, a parallel-to-serial (P-to-S) block 620, an add cyclic prefix block 625, and an up-converter (UC) 630. The receive path 700 includes a down-converter (DC) 755, a remove cyclic prefix block 760, a serial-to-parallel (S-to-P) block 765, a size-N fast Fourier transform (FFT) block 770, a parallel-to-serial (P-to-S) block 775, and a channel decoding and demodulation block 780.

[0063] As shown in FIG. 6, a channel coding and modulation block 605 receives a set of information bits and applies coding (e.g., low-density parity check (LDPC) coding) and modulates the input bits (e.g., quadrature phase shift keying (QPSK) or quadrature amplitude modulation (QAM)) to generate a series of frequency-domain modulation symbols.

[0064] The serial-to-parallel block 610 converts (e.g., de-multiplexes) the serial modulated symbols with parallel data to generate N parallel symbol streams, where N is the IFFT / FFT size used by the gNB 102 and the UE 116. The size-N IFFT block 615 performs an IFFT operation on the N parallel symbol streams to generate a time-domain output signal. The parallel-to-serial block 620 converts (e.g., multiplexes) the parallel time-domain output symbols from the size-N IFFT block 615 to generate a serial time-domain signal. The add cyclic prefix block 625 inserts a cyclic prefix into the time-domain signal. The upconverter 630 modulates (e.g., upconverts) the output of the cyclic prefix addition block 625 to an RF frequency for transmission over a wireless channel. The signal may be baseband filtered before further converting to an RF frequency.

[0065] The RF signal transmitted from gNB102 passes through a wireless channel and then reaches UE116, and the reverse operation of the operation in gNB102 is performed in UE116.

[0066] As shown in FIG. 7, downconverter 255 downconverts the received signal to baseband frequency and remove cyclic prefix block 760 removes the cyclic prefix to generate a serial time-domain baseband signal. Serial-to-parallel block 765 converts the time-domain baseband signal into a parallel time-domain signal. Size-N FFT block 770 performs an FFT algorithm to generate N parallel frequency-domain signals. Parallel-to-serial block 775 converts the parallel frequency-domain signals into a series of modulated data symbols. Channel decoding and demodulation block 780 demodulates and decodes the modulated symbols to recover the original input data stream.

[0067] Each of the gNBs 101-103 may implement a similar transmit path 600 for transmitting to the UEs 111-116 on the downlink as shown in Figure 6, and may implement a similar receive path 700 for receiving from the UEs 111-116 on the uplink as shown in Figure 7. Similarly, each of the UEs 111-116 may implement a transmit path 600 for transmitting to the gNBs 101-103 on the uplink, and may implement a receive path 700 for receiving from the gNBs 101-103 on the downlink.

[0068] Each of the components in Figures 6 and 7 may be implemented using only hardware or a combination of hardware and software / firmware. As a specific example, at least some of the components in Figures 6 and 7 may be implemented in software, while other components may be implemented as configurable hardware or a mixture of software and configurable hardware. For example, FFT block 770 and IFFT block 715 may be implemented as configurable software algorithms, where the value of the magnitude N may be modified depending on the implementation.

[0069] Also, although described using FFT and IFFT, this is merely an example and should not be construed as limiting the scope of the present disclosure. Other types of transforms can be used, such as discrete Fourier transform (DFT) and inverse discrete Fourier transform (IDFT) functions. It is understood that for DFT and IDFT functions, the value of the N variable can be any integer (e.g., 1, 4, 3, 4, etc.), while for FFT and IFFT functions, the value of the N variable can be any integer that is a power of 2 (i.e., 1, 2, 4, 8, 16, etc.).

[0070] Although Figures 6 and 7 illustrate example wireless transmit and receive paths, various modifications to Figures 6 and 7 may be made. For example, various components in Figures 6 and 7 may be combined, further subdivided, or omitted, and additional components may be added as needed. Also, Figures 6 and 7 are intended to illustrate examples of types of transmit and receive paths that may be used in a wireless network. Other suitable architectures may be used to support wireless communications in a wireless network.

[0071] The CSI report from the UE may be periodic (P-CSI report) and multiplexed with PUCCH transmission, or semi-permanent (SP-CSI report) and multiplexed with periodic PUCCH or PUSCH transmission configured by higher layers and activated by a DCI format, or aperiodic (A-CSI report) and multiplexed with PUSCH transmission scheduled by a DCI format. For example, PDSCH transmission using one CW may be applied for RI≦4, and PDSCH transmission using two CWs may be applied for RI>4, whereby the RI value determines the PMI bit width and the number of codewords (CWs), and the CSI report payload depends on the RI and / or CRI.

[0072] The number of CQIs is determined by the number of CWs. For example, there is one CQI per CW for one report per CQI reporting band ("wideband" or "subband"). Also, to report CRI when multiple non-zero-power (NZP) CSI-RS resources are configured in the UE, the RI / PMI / CQI payload can depend on the value of CRI when a variable number of ports are associated with different CSI-RS resources. Therefore, a CSI report with two parts (Part 1 CSI and Part 2 CSI) must be used.

[0073] Part 1 CSI contains additional information such as RI / CRI, CQI for the first CW, and in the case of Type II CSI, the number of non-zero amplitude coefficients for the two layers, and has a predetermined payload. Part 2 CSI contains RI and CRI information, and typically has a variable payload depending on the RI and CRI values. There are also conditions where the payload of the second part is independent of the content of the first part. In such scenarios, the use of two-part UCI can be simplified.

[0074] A subband for CSI reporting is defined as a set of contiguous PRBs. The number of PRBs in a subband can be predetermined in system operation as a function of DL system bandwidth provided by a higher layer or provided by a DCI format in the PDCCH. A configuration for CSI reporting can include multiple PRBs in a subband. A "CSI reporting band" is defined as a set of contiguous or non-contiguous subbands for CSI reporting. For example, the CSI reporting band can include all subbands within the DL system bandwidth (wideband CSI reporting). Alternatively, the CSI reporting band can include only a set of subbands within the DL system bandwidth, which is further referred to as partial-band CSI reporting.

[0075] The UE may be configured for CSI reporting for at least one CSI reporting band. Such configuration may be by configuration by a higher layer or a DCI format on the PDCCH. When configured to report CSI via multiple CSI reporting bands, such as when operating on mmWave carrier frequencies, the UE may report CSI for any subset of the N CSI reporting bands. The number of CSI reporting bands in the subset may be provided by a higher layer or indicated by a DCI format on the PDCCH triggering the CSI report. The UE may further recommend a value for the number of CSI reporting bands.

[0076] For CSI report generation, the UE may be provided with multiple configurations for the CSI-ReportConfig IE, for example as described in the NR specification, where the configurations may include (a) a table for mapping CQI values ​​to MCS index values ​​(or SE values), (b) whether the CSI report includes a single (wideband) or multiple (subband) CQIs, (c) signals to measure and number of CQIs to report, (d) periodicity and offsets for PUCCH transmission when the CSI report is multiplexed with PUCCH, (e) PUCCH resources for PUCCH transmission, etc.

[0077] A UE may be configured for communication with multiple service types that require different respective reception reliability quantified by block error rate (BLER) for transmission block (TB) reception. For example, a UE may simultaneously support mobile broadband (MBB) services such as web browsing or file download and ultra-reliable low latency services (URLLC) such as augmented reality or virtual reality (AR / VR), where URLLC requires a TB BLER that is at least 10 times smaller than that for MBB. For example, a serving gNB may target different BLERs for the TB depending on the signal-to-interference-and-noise ratio, or the path-loss (PL), or the reference signal received power (RSRP) experienced by the UE.

[0078] The A-CSI report may be triggered by the DCI format, and the UE may multiplex the A-CSI report with the associated PUSCH transmission or the associated PUCCH transmission with or without the TB. One value / state of the field indicates that no A-CSI report is multiplexed with the PUSCH transmission. Other values ​​of the field are configured by higher layers to map to one or more of the configurations of the CSI-ReportConfig information element (IE), for example, as described in the NR specification, which determines the content of the A-CSI report.

[0079] Also, since CSI reporting is generally associated with PDSCH reception, it is advantageous for the UE to trigger A-CSI reporting by a DCI format that schedules PDSCH reception by not monitoring the PDCCH for a DCI format that schedules PUSCH transmission. This may be the case where a search space set for PDCCH reception that provides a DCI format that schedules PUSCH transmission and can trigger A-CSI reporting is separate from a search space set for PDCCH reception that provides a DCI format that schedules PDSCH reception.

[0080] Including an A-CSI reporting trigger in a DCI format that schedules PDSCH reception by the UE can provide the intended functionality for triggering and multiplexing A-CSI reporting with PUCCH transmission, where the UE also reports HARQ-ACK information in response to the TB decoding result on the PDSCH. However, such a mechanism is error prone if the UE cannot detect the DCI format that schedules PDSCH reception and triggers A-CSI reporting, which causes a different understanding between the gNB and the UE regarding the total UCI payload and possibly the resources that the UE uses for PUCCH transmission.

[0081] When a UE supports multiple service types, CSI reports, and generally UCI, associated with different services may have different priorities reflecting the relative importance of each service. In the case of CSI reports multiplexed with a PUCCH transmission, the periodicity of each PDCCH transmission may be different, and therefore the UE may need to simultaneously transmit one or more PUCCHs with CSI reports of different priorities.

[0082] Multiplexing of CSI reports in a single PUCCH transmission may not be practically feasible when the CSI reports have different reception reliability requirements reflecting different reception reliability requirements of different services. Also, the UE needs to simultaneously transmit a first PUCCH with HARQ-ACK information or an SR associated with a first service type of a first priority and a second PUCCH with one or more CSI reports associated with a second service type of a second priority.

[0083] Therefore, there is a need to enable the UE to provide separate CSI reports, e.g., associated with different BLER targets, for TB decoding upon PDSCH reception. There is another need to enable the UE to provide multiple CSI reports, e.g., associated with respective multiple BLER targets, for TB decoding upon PDSCH reception. There is another need to enable triggering of A-CSI reporting using a DCI format that schedules PDSCH reception by the UE when A-CSI reporting by the UE is not triggered. Finally, there is another need to provide a mechanism for the UE to transmit a PUCCH when the UE transmits one or more PUCCHs simultaneously when each UCI type has a different transmission priority.

[0084] Various embodiments of the present disclosure may provide separate CSI reports associated with different targets for the BLER of TB decoding in PDSCH reception by the UE. Various embodiments of the present disclosure may further provide multiple CSI reports associated with respective multiple targets for the BLER of TB decoding in PDSCH reception by the UE. Various embodiments of the present disclosure may additionally trigger A-CSI reporting using a DCI format that schedules PDSCH reception by the UE when A-CSI reporting by the UE is not triggered. Various embodiments of the present disclosure further provide a mechanism for the UE to transmit a PUCCH when the UE transmits one or more PUCCHs simultaneously when each UCI type has a different transmission priority.

[0085] In one embodiment, a configuration for the UE is provided for the UE to provide multiple CQI reports for the same CSI report or for respective multiple CSI reports. For example, multiple CQI reports may be associated with respective multiple target BLERs for TB decoding in PDSCH reception. In one embodiment, enhancements are provided to the CSI-ReportConfig IE to configure the UE for the gNB to provide multiple CQI reports for a single CSI report corresponding to the BWP of the cell.

[0086] The UE may be configured to provide a set of CQI reports for a corresponding set of BLERs for TB decoding upon PDSCH reception. The CQI report values ​​are mapped to MCS index values ​​or SE (spectral efficiency) values ​​for the modulation and coding scheme of the TB in the PDSCH. Each mapping table is referred to as a cqi-Table in this disclosure. Each cqi-Table may be further associated with a BLER, whose association may be defined in system operation or may be provided to the UE by a higher layer as described below. For example, Tables 1 and 2 are first and second cqi-Tables that map MCS index values ​​of CQI reports to modulation orders and code rates.

[0087] [Table 1]

[0088] [Table 2]

[0089] For example, the UE may be configured with an enhanced CSI-ReportConfig IE to provide a CQI report indicating a first MCS index value of the cqi-Table and a second CQI report indicating a second MCS index value of the cqi-Table. The second CQI report may indicate an entry in the cqi-Table or may differ from the first CQI report by providing an offset to the first CQI report (by a minimum and maximum value). Also, the first BLER associated with the first MCS index value may be specified in system operation, while the second BLER associated with the second MCS index value may be provided by the enhanced CSI-ReportConfig IE or may be indicated by the UE as part of the CSI report. For example, the first MCS index value may be associated with a first BLER such as 0.1, and the second MCS index value may be associated with a second BLER such as 0.001 for TB decoding in PDSCH reception.

[0090] 8 illustrates a flow chart of a UE procedure 800 for providing a first CQI report and a second CQI report according to an embodiment of the present disclosure. The embodiment of the UE procedure 800 illustrated in FIG. 8 is for illustration purposes only. One or more of the components illustrated in FIG. 8 may be embodied with specialized circuitry configured to perform the functions described, or one or more of the components may be embodied with one or more processors executing instructions to perform the functions described. Other embodiments may be used without departing from the scope of the present disclosure.

[0091] As shown in Fig. 8, the UE is configured by a higher layer to provide a first CQI report and a second CQI report in a CSI report, where, for example, the first CQI report corresponds to a first BLER for TB decoding and the second CQI report corresponds to a second BLER for TB decoding. At least one of the first and second BLERs may be configured in the UE by a higher layer or reported by the UE in the CSI report in step 810. When the UE is not configured with a BLER for the CQI report or does not report a BLER in the CSI report, the BLER may be specified in the system operation.

[0092] The UE determines a first CQI report corresponding to the first BLER and a second CQI report corresponding to the second BLER in step 820. The UE multiplexes the first CQI report and the second CQI report in the same or separate PUCCH or PUSCH transmission in step 830.

[0093] For example, the UE may be configured with an enhanced CSI-ReportConfig IE to provide a first CQI report indicating a first MCS index value in a first cqi-Table and a second CQI report indicating a second MCS index value in a second cqi-Table. For example, the first and second cqi-Tables may be associated with respective first and second BLERs. Either or both of the first and second cqi-Tables may be defined in system operation or provided by the enhanced CSI-ReportConfig IE.

[0094] When the UE is configured to provide multiple CQI reports with the same CSI report, Part 1 CSI includes RI / CRI and multiple CQI reports. Depending on the system operation specification or configuration through higher layers, the UE can provide RI / CRI reports for each CQI report or provide a common RI / CRI report for each CQI report from multiple CQI reports. In the case of RI / CRI reports for each CQI report, a different PDSCH transmission rank can be enabled for each BLER, and a separate Part 2 CSI can be provided for the further CSI report. In the case of common RI / CRI reports for multiple CQI reports, the CSI report is the same as when providing a single CQI report with the only exception that the UE actually provides multiple CQI reports.

[0095] The multiple CQI reports may be separate (individual) CQI reports, or the multiple CQI reports may be differential values ​​with respect to a reference CQI report, except for one CQI report that serves as a reference. For example, the reference CQI report may be for the smallest BLER, for the largest BLER in a set of BLERs, or for a reference UE receiver configuration that is the same as that corresponding to the maximum number of UE receiver antenna ports. When the UE includes multiple CQI reports in a CSI report, the CSI report is the same as when the UE includes only one CQI report, but the UE is provided with multiple respective configurations for the multiple CQI reports. For example, the configuration for a CQI report may include an associated BLER value or an associated cqi-Table. Providing multiple CQI reports for the same CSI report may be more advantageous than providing a first CSI report including the first CQI in a first PUCCH transmission and a second CSI report including only the second CQI (without RI / CRI or PMI) in a second PUCCH transmission separately, especially since it may provide coding gain and reduce PUCCH overhead due to a larger overall payload for the second CQI.

[0096] 9 illustrates a flow chart of a UE procedure 900 for providing a first CQI report and a second CQI report in the same CSI report according to an embodiment of the present disclosure. The embodiment of the UE procedure 900 illustrated in FIG. 9 is for illustration purposes only. One or more of the components illustrated in FIG. 9 may be embodied with specialized circuitry configured to perform the functions described, or one or more of the components may be embodied with one or more processors executing instructions to perform the functions described. Other embodiments may be used without departing from the scope of the present disclosure.

[0097] As shown in FIG. 9, the UE is configured by a higher layer to provide a first CQI report 902 and a second CQI report 904 in the same CSI report, such as Part 1 CSI 906 of the CSI report, in step 910. For example, the first and second CQI reports may correspond to a first and second BLER, or a first and second UE receiver antenna or gNB transmitter antenna configuration, or a first cqi-Table and a second cqi-Table. The UE determines a first CQI report and a second CQI report in step 920. The UE includes the first CQI report and the second CQI report in the CSI report in step 930. The CSI report may further include an RI / CRI indication for the Part 1 CSI and additional information for the Part 2 CSI. The UE multiplexes the CSI report in a PUCCH or PUSCH transmission in step 940.

[0098] When a UE is configured to provide multiple CSI reports in multiple respective PUCCH transmissions, the UE needs to transmit one or more PUCCHs providing one or more respective CSI reports on time-overlapping PUCCH resources. The UE may be configured to multiplex one or more CSI reports in a single PUCCH transmission or to drop some of the one or more PUCCH transmissions and multiplex the CSI reports from the remaining PUCCHs in a single PUCCH transmission. For example, the UE may drop all but one of the time-overlapping PUCCH transmissions. When the UE is configured to multiplex CSI reports in a single PUCCH transmission, the UE may be further configured with separate PUCCH resources to determine the PUCCH resource for the single PUCCH transmission.

[0099] The UE may further determine which CSI reports to transmit on a single PUCCH based on a transmission priority that may be part of a configuration for an enhanced CSI-ReportConfig IE. In the following, it is assumed that the priority is in descending order of index, but the same principle applies when the priority is in ascending order of index. For example, when the priority is in descending order of index, a first CSI report may be set to a transmission priority of 0 and a second CSI report may be set to a transmission priority of 1 according to a corresponding value of a priority parameter of the corresponding CSI-ReportConfig IE, and when the UE determines that corresponding PUCCH transmissions overlap in time, the UE transmits only the PUCCH with the CSI report associated with the lower transmission priority of 0.

[0100] For example, a first CSI reporting configuration may have a transmission priority of 0 and a second CSI reporting configuration may have a transmission priority of 1, and when corresponding PUCCH transmissions overlap in time, the UE may be configured to multiplex the CSI reports in a single PUCCH transmission or transmit a CSI report associated with a lower value (corresponding to a higher priority) for a parameter priority provided by the CSI-ReportConfig IE. Instead of a default UE behavior of not multiplexing CSI reports with different transmission priorities, whether the UE performs such multiplexing may depend on a corresponding configuration for the UE by a higher layer that may be configured for the UE for multiple CSI reports with different transmission priority values ​​set. When such a configuration is not provided for the UE, the default behavior for the UE may be not to multiplex CSI reports associated with different transmission priorities in a PUCCH transmission.

[0101] Similarly, if a UE transmits a PUCCH with HARQ-ACK information having a first priority and a PUCCH with a CSI report having a second priority, and the UE determines that the two PUCCH transmissions overlap in time, the UE may transmit a PUCCH with a UCI (HARQ-ACK information or CSI report) with a higher priority and multiplex the HARQ-ACK information and the CSI report when they have the same priority in the same PUCCH. Instead of multiplexing the CSI report and HARQ-ACK information with different priorities, which is the default UE behavior, whether the UE performs such multiplexing may depend on a corresponding configuration for the UE by a higher layer indicating that multiplexing of HARQ-ACK information and CSI reports with different priorities in a PUCCH transmission is activated. Such a configuration may be the same as or separate from the configuration for multiplexing CSI reports of different priorities in the same PUCCH.

[0102] 10 illustrates a flow chart of a UE procedure 1000 for determining a CSI report to transmit on a PUCCH when a UE is configured to transmit multiple CSI reports on multiple PUCCHs with time-overlapping resources, according to an embodiment of the present disclosure. The embodiment of the UE procedure 1000 illustrated in FIG. 10 is for illustrative purposes only. One or more components illustrated in FIG. 10 may be embodied with specialized circuitry configured to perform the functions described, or one or more components may be embodied by one or more processors executing instructions to perform the functions described. Other embodiments may be used without departing from the scope of the present disclosure.

[0103] The UE is configured by a higher layer to multiplex a first CSI report in a first PUCCH transmission and a second CSI report in a second PUCCH transmission in step 1010. The first and second CQI reports include respective first and second CQI reports that may be associated with different cqi-Tables. The UE determines whether the first and second PUCCH transmissions overlap in time in step 1020. When the first and second PUCCH transmissions do not overlap in time, the UE transmits the first PUCCH with the first CSI report and transmits the second PUCCH with the second CSI report in step 1030. When the first and second PUCCH transmissions overlap in time, the UE determines the value of a priority parameter included in an IE that configures the transmission of each CSI report on the PUCCH in step 1040, such as a CSI-ReportConfig IE, and transmits the first PUCCH together with the first CSI report when the corresponding priority value is lower in step 1050, and transmits the second PUCCH together with the second CSI report when the corresponding priority value is lower in step 1060.

[0104] For demodulation of data symbols and decoding of TB in PDSCH reception, the UE needs to know the MCS table corresponding to the MCS field value in the DCI format for scheduling PDSCH reception in order to determine the appropriate entry indicating the modulation order and the code rate. The determination of the MCS table can be activated by a number of means. For example, in the case of a DCI format for scheduling PDSCH reception, a first DCI format can be associated with a first MCS table, and a second DCI format can be associated with a second MCS table. The first DCI format can further be associated with a first priority, and the second DCI format can be associated with a second priority. For example, in the case of a DCI format for scheduling PDSCH reception, a first value of the priority indicator field of the DCI format can be associated with the first MCS table, and a second value of the priority indicator field of the DCI format can be associated with the second MCS table. The UE determines the priority of the HARQ-ACK information (or the priority of the PUCCH containing the HARQ-ACK information) generated by the UE in response to the TB provided in the PDSCH reception according to the value of the priority indicator field.

[0105] The same approach can be applied to a DCI format for scheduling PUSCH transmission. For example, in the case of a DCI format for scheduling PUSCH transmission, different DCI formats or different values ​​of the priority indicator field in the DCI format can be used to map values ​​of the MCS field in the DCI format to determine an MCS table for determining the priority of the UL-SCH TB in PUSCH transmission (or for determining the priority of PUSCH transmission).

[0106] The association of values ​​for the priority indicator field of the DCI format to the MCS tables may be provided by a higher layer or may be pre-determined in system operation. For example, higher layer signaling from the gNB may indicate to the UE that a first value of the priority indicator field is associated with a first MCS table specified in system operation and a second value of the priority indicator field is associated with a third MCS table specified in system operation. For example, the UE may be provided by a higher layer with an association of a priority indicator field value of 0 to the first MCS table and an association of a priority indicator field value of 1 to the third MCS table. In general, the UE may be provided by a higher layer with an association of a priority indicator field value of 0 to the first MCS table from a pre-determined or configured MCS table set and an association of a priority indicator field value of 1 to the second MCS table from a pre-determined or configured MCS table set. Alternatively, instead of being configured by a higher layer, the mapping between the priority indicator field and the values ​​of the MCS tables may be pre-determined in system operation. Instead of associating the value of the priority indicator field of the DCI format with an MCS table (cqi-Table), it is also possible to introduce a separate field in the DCI format, where the field indicates an MCS table (cqi-Table) from a configured or predetermined set of MCS tables.

[0107] In one embodiment, it is contemplated that A-CSI reporting may be triggered by a DCI format associated with the scheduling of PDSCH reception.

[0108] A UE may be configured with separate search space sets for monitoring a PDCCH having a DCI format that schedules PDSCH reception by the UE and for monitoring a PDCCH having a DCI format that schedules PUSCH transmission from the UE. For example, when a UE has DL dominant traffic such as file download or web browsing and sparse UL traffic, the search space set for a first DCI format that schedules PDSCH reception may have a smaller period than the search space set for a second DCI format that schedules PUSCH transmission. It is then advantageous to trigger an A-CSI report by the first DCI format to avoid the larger waiting time required by using the second DCI format.

[0109] The first DCI format for scheduling PDSCH reception by the UE may include an A-CSI trigger field. The A-CSI trigger field may be the same or different from the A-CSI trigger field in the second DCI format for scheduling PUSCH transmission from the UE. If the A-CSI trigger field is the same in both the first and second DCI formats, the UE may be provided with a single configuration for mapping the state of the A-CSI trigger field to the content of the A-CSI report. If the A-CSI trigger field differs in magnitude or state mapping in the first and second DCI formats, the UE may be provided with separate configurations for mapping the state of the A-CSI trigger field to the content of the A-CSI report for the first and second DCI formats.

[0110] If the A-CSI trigger field of a DCI format used to schedule PDSCH reception triggers an A-CSI report by the UE, the contents / bits of the DCI format other than for the A-CSI trigger field may be reinterpreted to schedule PUSCH or PUCCH transmission instead of PDSCH reception.

[0111] In one example, whether a DCI format schedules a PUSCH transmission or a PUCCH transmission can be configured in the UE by a higher layer. In another example, whether a DCI format schedules a PUSCH transmission or a PUCCH transmission can be indicated to the UE by the reinterpreted content of the DCI format. For A-CSI report multiplexing with PUCCH transmission, the UE can be provided with a separate resource configuration by a higher layer for PUCCH transmission with HARQ-ACK information.

[0112] When the DCI format schedules a PUSCH transmission together with an A-CSI report, reinterpretation of the bits of the DCI format (bits other than the A-CSI report trigger bit) may provide one or more of the following information fields: whether the DCI format has scheduled a PUSCH transmission (if this information is provided by the DCI format), for example using one bit, or whether it has scheduled a PUCCH transmission; a carrier indicator; a BWP indicator; a frequency domain resource allocation for PUSCH transmission; a time domain resource allocation for PUSCH transmission; a frequency hopping flag; an MCS for the A-CSI report modulation and coding scheme; a transmit power control (TPC) command; an SRS resource indicator; an SRS request; a supplementary UL (SUL) carrier indicator for whether the PUSCH transmission is on a UL or SUL carrier; and / or a reserved beat or additional field.

[0113] When the DCI format schedules PUCCH transmission together with an A-CSI report, reinterpretation of the bits of the DCI format (bits other than the A-CSI report trigger bit) can provide one or more of the following information fields: a PUCCH resource indicator providing a PUCCH resource; a PDCCH to CSI report timing indicator providing a slot for PUCCH transmission relative to a slot of PDCCH reception having the DCI format; and / or a TPC command for PUCCH transmission.

[0114] FIG. 11 illustrates a flow chart of a UE procedure 1100 for determining A-CSI reporting triggering a PUSCH transmission over a PUCCH transmission based on detection of a DCI format also used to schedule PDSCH reception according to an embodiment of the present disclosure. The embodiment of the UE procedure 1100 illustrated in FIG. 11 is for illustrative purposes only. One or more components illustrated in FIG. 11 may be embodied with specialized circuitry configured to perform the functions described, or one or more components may be embodied by one or more processors executing instructions to perform the functions described. Other embodiments may be used without departing from the scope of the present disclosure.

[0115] The UE detects a DCI format that can be used to schedule PDSCH reception or multiplexing of the A-CSI report with a PUSCH or PUCCH transmission in step 1110. The UE determines whether an A-CSI report trigger field in the DCI format schedules multiplexing of the A-CSI report with a PUSCH or PUCCH transmission in step 1120. If the A-CSI report trigger field triggers multiplexing of the A-CSI report with a PUSCH or PUCCH transmission, the UE reinterprets the information of the DCI format as scheduling a PUSCH or PUCCH transmission with an A-CSI report as indicated by the value of the A-CSI report trigger field in step 1130. If the A-CSI report trigger field does not trigger multiplexing of the A-CSI report with a PUSCH or PUCCH transmission, the UE receives the PDSCH according to the DCI format in step 1140.

[0116] In one embodiment, the decision to transmit a PUSCH or PUCCH channel is taken into account, including the power allocation for the transmission, based on the respective priorities.

[0117] The UE transmits the maximum total power P CMAX(i) exceeding the priority value for the first CSI report, the UE may determine a priority for power allocation for the channel or signal transmission based on the respective transmission priorities. For example, if a UE transmits a first PUCCH with a first CSI report on a first cell, such as a primary cell (PCell), and a second PUCCH with a second CSI report on a second cell, such as a primary secondary cell (PSCell), and the priority value for the second CSI report is less than the priority value for the first CSI report, the UE may prioritize power allocation for the second PUCCH transmission on the PSCell.

[0118] The same principle can be extended to the transmission of other information that can be associated with a priority value, such as a scheduling request (SR), HARQ-ACK information in response to SPS PDSCH reception, periodic PUSCH transmissions, etc. For example, the first and second PUCCH transmissions may overlap in time, otherwise the total transmit power may be P CMAX(i) If the first PUCCH transmission associated with the configuration for HARQ-ACK information or SR has a priority value that is lower than the priority value associated with the configuration for HARQ-ACK information or SR associated with the second PUCCH transmission when the priority value exceeds the priority value, the UE prioritizes power allocation for the first PUCCH transmission with HARQ-ACK information or SR over the second PUCCH transmission with HARQ-ACK information or SR.

[0119] The transmission priority for data information or UCI can be further used by the UE to determine multiplexing of UCI in PUSCH transmission. For example, based on an indication by a DCI format that schedules PUSCH transmission or an indication from a configuration of PUSCH transmission by a higher layer, the UE can determine a transmission priority for PUSCH transmission. For example, if PUSCH transmission is scheduled by a DCI format, the UE can determine a priority for PUSCH transmission based on a DCI format size, based on an RNTI that scrambles a CRC of the DCI format, or based on an explicit indication by a priority indicator field of the DCI format. Based on an indication by a DCI format that schedules PDSCH reception and triggers multiplexing of associated HARQ-ACK information in PUCCH transmission, or based on an indication from a configuration of PUCCH transmission by a higher layer, the UE can determine a corresponding priority for PUCCH transmission (or UCI multiplexed in PUCCH transmission).

[0120] If PUSCH transmission and PUCCH transmission overlap in time and the UE is not capable of or configured for simultaneous PUSCH and PUCCH transmission, the UE may decide to multiplex UCI with PUSCH and transmit PUSCH when UCI / PUCCH and UL-SCH / PUSCH are associated with the same priority, transmit only PUSCH without multiplexing UCI and not transmit PUCCH when PUSCH is associated with a lower priority parameter value (higher priority) than PUCCH, or transmit only PUCCH and not transmit PUSCH when PUCCH is associated with a lower priority parameter value (higher priority) than PUSCH. When the UE transmits multiple PUSCHs, for example, when the UE operates in UL carrier aggregation and PUCCH is associated with a lower priority parameter value (higher priority) than all of the multiple PUSCHs, the UE does not transmit multiple PUSCHs. When the PUSCH and PUCCH transmissions are overlapped in time and the UE is configured for simultaneous PUSCH and PUCCH transmissions, the UE transmits both PUSCH and PUCCH.

[0121] Similar to multiplexing UCI types with different priorities on the PUCCH, whether the UE multiplexes UCIs with different priorities and TB / UL-SCH on the PUSCH can be activated by higher layer signaling from the serving gNB. A configuration can be provided for each UCI type, and separate configurations can be provided for multiplexing HARQ-ACK information and multiplexing CSI reports. Synchronization can be performed for different UCI types with different importance and different payload or reception reliability requirements. For example, the UE may be indicated to multiplex HARQ-ACK information and not indicated to multiplex CSI reports with different priorities from the TB / UL-SCH priorities on the PUSCH.

[0122] The configuration can be further performed for each priority value or can be separated for each priority value. For example, synchronization may be preferred to multiplex higher priority HARQ-ACK information on lower priority TB / UL-SCH and PUSCH since the importance of HARQ-ACK information is greater and the payload is generally smaller, and the potential negative impact on the lower priority TB / UL-SCH can be tolerated, but the opposite may not apply (in this case, in case of overlap, the UE drops the PUCCH transmission with lower priority HARQ-ACK information and transmits a PUSCH with higher priority TB / UL-SCH). For example, the UE may be indicated to multiplex higher priority HARQ-ACK information on a PUSCH with a lower priority TB / UL-SCH, and may not be indicated to multiplex lower priority HARQ-ACK information on a PUSCH with a higher priority TB / UL-SCH. The configuration can be further separated for PUSCH transmission scheduled by DCI format and PUSCH transmission configured by higher layer. The same procedure can be applied when multiplexing UCI types of different priority on the same PUCCH, for example, the UE can be provided with a first indication for multiplexing lower priority HARQ-ACK information with a higher priority CSI report on the PUCCH, and a second indication for multiplexing higher priority HARQ-ACK information with a lower priority CSI report on the PUCCH (in this case, in case of overlap, the UE drops the PUCCH with the lower priority CSI report and transmits the PUCCH with the higher priority HARQ-ACK information).

[0123] 12 illustrates a flow chart of a UE procedure 1200 for determining whether to multiplex UCI in a PUSCH or PUCCH when a UE simultaneously transmits a PUSCH and a PUCCH according to an embodiment of the present disclosure. The embodiment of the UE procedure 1200 illustrated in FIG. 12 is for illustrative purposes only. One or more components illustrated in FIG. 12 may be embodied in specialized circuitry configured to perform the functions described, or one or more components may be embodied by one or more processors executing instructions to perform the functions described. Other embodiments may be used without departing from the scope of the present disclosure.

[0124] As shown in Figure 12, the UE may transmit one or more PUSCHs and PUCCHs simultaneously in step 1210. The UE determines a priority for the PUCCH transmission (or UCI in a PUCCH transmission) and a priority for one or more PUSCH transmissions (or data or UCI in a PUSCH transmission) with the same priority in step 1220. The UE determines whether the UE may transmit a PUCCH and one or more PUSCHs simultaneously in step 1230. If the UE transmits a PUCCH and one or more PUSCHs simultaneously, the UE determines whether the PUCCH priority is equal to the priority for one or more PUSCHs in step 1240.

[0125] If the PUCCH priority is equal to the priority for one or more PUSCHs, the UE multiplexes UCI from one or more PUSCHs onto the PUSCH, transmits one or more PUSCHs, and does not transmit the PUCCH in step 1250. If the PUCCH priority is not equal to the priority for one or more PUSCHs, the UE determines whether the PUCCH priority is greater than the priority for one or more PUSCHs in step 1260. If the PUCCH priority is greater than the priority for one or more PUSCHs, the UE does not multiplex UCI from the PUCCH, transmits one or more PUSCHs, and does not transmit the PUCCH in step 1270. If the PUCCH priority is less than the priority for one or more PUSCHs, the UE transmits the PUCCH with UCI in step 1280, and does not transmit any of the one or more PUSCHs. If the UE can transmit the PUCCH and one or more PUSCHs simultaneously, the UE transmits the PUCCH and one or more PUSCHs in step 1290.
