Description

Technical Field

[0001] The present application relates generally to wireless communications and, in particular embodiments, to methods and apparatus for adjusting configurations for converting between analog and digital signals. Background Art

[0002] In some wireless communication systems, electronic devices such as user equipment (UE) communicate wirelessly with the network through one or more transmit-and-receive points (TRP). The TRP can be a terrestrial TRP (T-TRP) or a non-terrestrial TRP (NT-TRP). An example of a T-TRP is a fixed base station or NodeB. An example of an NT-TRP is a TRP that can be moved in space for repositioning, for example, a TRP mounted on a drone, an aircraft, and / or a satellite, etc.

[0003] Wireless communication from UE to TRP is called uplink communication. Wireless communication from TRP to UE is called downlink communication. Resources are required to perform uplink and downlink communications. For example, TRP can send information to UE wirelessly in downlink communication at a specific frequency (or frequency range) during a specific time period. Frequency and time period are examples of resources, which are generally called time-frequency resources. Multiple access occurs when more than one UE is scheduled on a set of time-frequency resources. Each UE uses a portion of the time-frequency resources to receive data from the TRP in case of downlink communication, or send data to the TRP in case of uplink communication.

[0004] The UE and the TRP may each use a corresponding analog-to-digital converter (ADC) and / or a digital-to-analog converter (DAC). For example, the ADC may be used to convert an analog signal received through a wireless channel into digital bits, and the DAC may be used to convert digital bits into analog signals for transmission through the wireless channel. In general, the resolution of the ADC and the resolution of the DAC may be represented by the number of bits (e.g., N bits) used to convert between analog samples and digital samples. For simplicity, the ADC and the DAC may be identified as an N-bit ADC and an N-bit DAC, respectively, to indicate their respective resolutions.

[0005] When the ADC / DAC resolution is high (i.e., N is large), the ADC and DAC can produce relatively high-precision outputs. For example, when N is large, the ADC can produce a high-precision digital output signal because more bits are used when digitizing the analog input signal. However, high ADC / DAC resolution comes with greater energy consumption. In fact, as the ADC / DAC resolution increases, the energy consumption of the ADC / DAC may increase exponentially. Summary of the invention

[0006] It is not always desirable to use a high ADC / DAC resolution due to high energy consumption. However, a low ADC / DAC resolution is not always ideal. For example, given that the signal-to-noise ratio (SNR) of the output signal of an N-bit ADC can be calculated by 6.02*N+1.76dB+10*lg(Fs / 2BW), where N is the number of bits indicating the resolution of the ADC, dB is the decibel indicating the ratio difference between two signals (e.g., the difference in power, voltage, or signal strength between two points in a cable or network), Fs is the sampling rate, and BW is the signal bandwidth, if N is small (i.e., low ADC resolution), the SNR of the output signal of the N-bit ADC will also be small. Therefore, due to low signal quality, low ADC / DAC resolution is undesirable and unacceptable in some cases. This shows that in some cases, a high ADC / DAC resolution may be required to obtain high throughput, while in other cases, a low ADC / DAC resolution may be more desirable to save power. Therefore, it is advantageous to provide multiple configurations for ADC / DACs with different ADC / DAC resolutions and support dynamic switching between different ADC / DAC resolutions.

[0007] In long term evolution (LTE) and new radio (NR), the resolution of the analog digital converter (ADC) and the resolution of the digital analog converter (DAC) are not clearly specified in the protocol, so many aspects of ADC / DAC resolution are yet to be implemented. According to existing wireless communication protocols, the transmit-and-receive point (TRP) (e.g., base station (BS)) is not aware of the operating configuration of the ADC / DAC resolution in the user equipment (UE). In other words, the TRP does not know whether the UE is operating with a high ADC / DAC resolution or a low ADC / DAC resolution. Therefore, there are some technical problems when adjusting the configuration of the ADC / DAC according to the current protocol or dynamically switching between different ADC / DAC resolutions. For example, if the UE reports a channel quality indicator (CQI) index based on a high ADC resolution and changes its operating configuration to use a low ADC resolution after reporting, the UE may experience decoding failures because the TRP uses a larger modulation and coding scheme (MCS) value based on the assumption that the UE's downlink signal quality is better than the UE's actual downlink signal quality. Based on the report, the TRP assumes that the UE uses a high ADC resolution. Since the assumption is incorrect, the UE will not be able to decode the signal sent from the TRP. On the other hand, if the UE reports a CQI index based on a low ADC resolution but uses a high ADC resolution when decoding the signal on the physical downlink shared channel (PDSCH), the transmission efficiency will be reduced due to the smaller MCS value.

[0052] In the present invention, an “analog-to-digital converter (ADC)” refers to a system for converting an analog signal into a digital signal, and a digital-to-analog converter (DAC) refers to a system for converting a digital signal into an analog signal.

[0053] In the present invention, "ADC resolution" or "resolution of the ADC" is defined as the smallest incremental voltage that can be recognized and thus cause a change in the digital output. ADC resolution is expressed as the number of bits that the ADC can output, and can therefore be called bit resolution. For example, for an n-bit ADC, the number of discrete digital values ​​that the ADC can output may be 2 n .

[0054] In the present invention, "DAC resolution" or "resolution of a DAC" is the smallest output increment that a DAC can produce. DAC resolution can be determined based on the number of bits (N) and can be expressed as range / 2. n The calculation is: where range is the full scale value that the DAC can measure. This resolution can be called bit resolution. DAC bit resolution can also be expressed as a percentage value. For example, for an n-bit DAC, the DAC resolution can be 1 / 2 n .

[0055] For illustrative purposes, specific exemplary embodiments are explained in detail below with reference to the accompanying drawings.

[0056] Exemplary Communication Systems and Devices

[0057] refer to Figure 1 , Figure 1is a non-limiting illustrative example, and a simplified schematic diagram of a communication system 100 is provided. The communication system 100 includes a radio access network (RAN) 120. The radio access network 120 can be a next generation (e.g., sixth generation (6G) or higher) radio access network or a traditional (e.g., 5G, 4G, 3G or 2G) radio access network. One or more communication electronic devices (ED) 110a to 120j (generally referred to as 110) can be interconnected with each other or connected to one or more network nodes (170a and 170b, generally referred to as 170) in the radio access network 120. The core network 130 can be part of the communication system and can be dependent on or independent of the radio access technology used in the communication system 100. In addition, the communication system 100 includes a public switched telephone network (PSTN) 140, the Internet 150, and other networks 160.

[0058] Figure 2 An exemplary communication system 100 is shown. In general, the communication system 100 enables multiple wireless or wired units to transmit data and other content. The purpose of the communication system 100 may be to provide content such as voice, data, video and / or text through broadcast, multicast and unicast, etc. The communication system 100 can operate by sharing resources such as carrier spectrum bandwidth between its constituent units. The communication system 100 may include a terrestrial communication system and / or a non-terrestrial communication system. The communication system 100 may provide a variety of communication services and applications (e.g., earth monitoring, remote sensing, passive sensing and positioning, navigation and tracking, autonomous delivery and mobility, etc.). The communication system 100 may provide a high degree of availability and robustness through the joint operation of a terrestrial communication system and a non-terrestrial communication system. For example, integrating a non-terrestrial communication system (or its components) into a terrestrial communication system may produce a heterogeneous network including multiple layers. Compared with traditional communication networks, heterogeneous networks can achieve better overall performance through efficient multi-link joint operation, more flexible function sharing, and faster physical layer link switching between terrestrial networks and non-terrestrial networks.

[0059] The terrestrial communication system and the non-terrestrial communication system may be subsystems in the communication system. In the example shown, the communication system 100 includes electronic devices (ED) 110a to 110d (generally referred to as ED 110), radio access networks (RAN) 120a and 120b, non-terrestrial communication networks 120c (which may also be RAN or part of RAN), core network 130, public switched telephone network (PSTN) 140, Internet 150 and other networks 160. RAN 120a and 120b include corresponding base stations (BS) 170a and 170b, which may be generally referred to as terrestrial transmit and receive points (T-TRP) 170a and 170b. The non-terrestrial communication network 120 c includes an access node 120 c , which may generally be referred to as a non-terrestrial transmit and receive point (NT-TRP) 172 .

[0060] Any ED 110 may alternatively or additionally be used to connect, access, or communicate with any other T-TRP 170a and 170b, NT-TRP 172, Internet 150, core network 130, PSTN 140, other network 160, or any combination thereof. In some examples, ED 110a may perform uplink and / or downlink transmissions with T-TRP 170a via interface 190a. In some examples, ED 110a, 110b, and 110d may also communicate directly with each other via one or more sidelink air interfaces 190b. In some examples, ED 110d may perform uplink and / or downlink transmissions with NT-TRP 172 via interface 190c.

[0061] The air interfaces 190a and 190b may use similar communication technologies, such as any suitable wireless access technology. For example, the communication system 100 may implement one or more channel access methods in the air interfaces 190a and 190b, such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal FDMA (OFDMA), or single-carrier FDMA (SC-FDMA). The air interfaces 190a and 190b may utilize other high-dimensional signal spaces, which may include a combination of orthogonal dimensions and / or non-orthogonal dimensions.

[0062] Air interface 190c may enable communication between ED 110d and one or more NT-TRPs 172 via a wireless link or a simple link. In some examples, the link is a dedicated connection for unicast transmission, a connection for broadcast transmission, or a connection between a group of EDs and one or more NT-TRPs for multicast transmission.

[0063] The RANs 120a and 120b communicate with the core network 130 to provide various services, such as voice, data, and other services, to the EDs 110a, 110b, and 110c. The RANs 120a and 120b and / or the core network 130 may communicate directly or indirectly with one or more other RANs (not shown), which may or may not be directly served by the core network 130 and may or may not use the same radio access technology as the RANs 120a, 120b, or both. The core network 130 may also serve as a gateway access between (i) the RANs 120a and 120b or the EDs 110a, 110b, and 110c, or both, and (ii) other networks, such as the PSTN 140, the Internet 150, and other networks 160. In addition, some or all of the EDs 110a, 110b, and 110c may include functionality for communicating with different wireless networks over different radio links using different radio technologies and / or protocols. Instead of (or in addition to) wireless communication, EDs 110a, 110b, and 110c may communicate with a service provider or switch (not shown) and with the Internet 150 via a wired communication channel. PSTN 140 may include a circuit-switched telephone network for providing plain old telephone service (POTS). Internet 150 may include computer networks and / or subnets (intranets), and include protocols such as Internet Protocol (IP), Transmission Control Protocol (TCP), and User Datagram Protocol (UDP). EDs 110a, 110b, and 110c may be multi-mode devices capable of operating according to a variety of wireless access technologies, and may include a plurality of transceivers required to support these technologies.

[0064] Figure 3Another example of ED 110, base station 170 (e.g., 170a and / or 170b), hereinafter referred to as T-TRP 170 and NT-TRP 172, is shown. ED 110 is used to connect people, objects, machines, etc. ED 110 can be widely used in various scenarios, such as cellular communication, device-to-device (D2D), vehicle to everything (V2X), peer-to-peer (P2P), machine-to-machine (M2M), machine-type communication (MTC), Internet of Things (IoT), virtual reality (VR), augmented reality (AR), industrial control, autonomous driving, telemedicine, smart grid, smart furniture, smart office, smart wear, smart transportation, smart city, drone, robot, remote sensing, passive sensing, positioning, navigation and tracking, autonomous delivery and mobility, etc.

Base stations 170a and 170b are T-TRPs, hereinafter referred to as T-TRP 170. Similarly, Figure 3 As shown, the NT-TRP is hereinafter referred to as NT-TRP 172. Each ED 110 connected to T-TRP 170 and / or NT-TRP 172 can be dynamically or semi-statically started (i.e., established, activated, or enabled), shut down (i.e., released, deactivated, or disabled), and / or configured in response to one or more of connection availability and connection necessity.

[0066] ED 110 includes a transmitter 201 and a receiver 203 coupled to one or more antennas 204. Only one antenna 204 is shown. One, some or all of the antennas may alternatively be panels. Transmitter 201 and receiver 203 may be integrated, for example, as a transceiver. The transmitter (or transceiver) is used to modulate data or other content so that it can be sent through at least one antenna 204 or a network interface controller (NIC). The receiver (or transceiver) is used to demodulate data or other content received through at least one antenna 204. Each transceiver includes any suitable structure for generating signals for wireless or wired transmission and / or for processing signals received wirelessly or wired. Each antenna 204 includes any suitable structure for sending and / or receiving wireless signals or wired signals.

[0067] ED 110 includes at least one memory 208. Memory 208 stores instructions and data used, generated, or collected by ED 110. For example, memory 208 may store software instructions or modules that implement some or all of the functions and / or embodiments described herein and are executed by one or more processing units 210. Each memory 208 includes any suitable one or more volatile and / or non-volatile storage and retrieval devices. Any suitable type of memory may be used, such as random access memory (RAM), read only memory (ROM), hard disk, optical disk, subscriber identity module (SIM) card, memory stick, secure digital (SD) card, processor cache, etc.

[0068] ED 110 may also include one or more input / output devices (not shown) or interfaces (e.g., Figure 1 The input / output devices support interaction with users or other devices in the network. Each input / output device includes any suitable structure for providing information to or receiving information from a user, such as a speaker, microphone, keypad, keyboard, display or touch screen, including network interface communications.

[0069] ED 110 also includes a processor 210 for performing operations related to preparing uplink transmissions to be sent to NT-TRP 172 and / or T-TRP 170, operations related to processing downlink transmissions received from NT-TRP 172 and / or T-TRP 170, and operations related to processing sidelink transmissions to and from other ED 110. Processing operations related to preparing uplink transmissions may include operations such as encoding, modulation, transmit beamforming, and generating symbols for transmission. Processing operations related to processing downlink transmissions may include operations such as receive beamforming, demodulation, and decoding received symbols. According to an embodiment, the downlink transmission may be received by receiver 203 using receive beamforming, and processor 210 may extract signaling from the downlink transmission (e.g., by detecting and / or decoding the signaling). An example of signaling may be a reference signal sent by NT-TRP 172 and / or T-TRP 170. In some embodiments, the processor 276 implements transmit beamforming and / or receive beamforming according to a beam direction indication (e.g., beam angle information (BAI)) received from the T-TRP 170. In some embodiments, the processor 210 may perform operations related to network access (e.g., initial access) and / or downlink synchronization, such as operations related to detecting a synchronization sequence, decoding, and obtaining system information. In some embodiments, the processor 210 may perform channel estimation using a reference signal received from the NT-TRP 172 and / or the T-TRP 170, for example.

[0070] The processor 210 may be part of the transmitter 201 and / or part of the receiver 203, but is not shown. The memory 208 may be part of the processor 210, but is not shown.

[0071] The processor 210, the processing components in the transmitter 201, and the processing components in the receiver 203 may be implemented by the same or different one or more processors, respectively, which are used to execute instructions stored in a memory (e.g., the memory 208). Alternatively, some or all of the processor 210, the processing components in the transmitter 201, and the processing components in the receiver 203 may be implemented using a programmed field-programmable gate array (FPGA), a graphical processing unit (GPU), or an application-specific integrated circuit (ASIC).

[0072] In some implementations, the T-TRP 170 may be represented by other names, such as a base station, a base transceiver station (BTS), a wireless base station, a network node, a network device, a network-side device, a transmitting / receiving node, a NodeB, an evolved NodeB (eNodeB or eNB), a home eNodeB, a next generation NodeB (gNB), a transmission point (TP), a site controller, an access point (AP) or a wireless router, a relay station, a ground node, a ground network device, or a ground base station, a baseband unit (BBU), a remote radio unit (RRU), an active antenna unit (AAU), a remote radio head (RRH), a central unit (CU), a distributed unit (DU), a positioning node, etc. The T-TRP 170 may be a macro BS, a micro BS, a relay node, a donor node, etc., or a combination thereof. T-TRP 170 may refer to the above-mentioned device, or may refer to a device in the above-mentioned device (eg, a communication module, a modem, or a chip).

[0073] In some embodiments, various parts of T-TRP 170 can be distributed. For example, some modules in T-TRP 170 can be remote from the device that houses the antenna of T-TRP 170, and can be coupled to the device that houses the antenna through a communication link (not shown) sometimes called a fronthaul (e.g., a common public radio interface (CPRI)). Therefore, in some embodiments, the term "T-TRP 170" can also refer to a network-side module that performs the following processing operations: for example, determining the location of ED 110, resource allocation (scheduling), message generation, and encoding / decoding, which modules are not necessarily part of the device that houses the antenna of T-TRP 170. These modules can also be coupled to other T-TRPs. In some embodiments, T-TRP 170 can actually be multiple T-TRPs that operate together to serve ED 110 through coordinated multi-point transmission, etc.

[0074] The T-TRP 170 includes at least one transmitter 252 and at least one receiver 254 coupled to one or more antennas 256. Only one antenna 256 is shown. One, some or all of the antennas may be panels. The transmitter 252 and the receiver 254 may be integrated as a transceiver. The T-TRP 170 also includes a processor 260 for performing operations related to preparing downlink transmissions sent to the ED 110, processing uplink transmissions received from the ED 110, preparing backhaul transmissions sent to the NT-TRP 172, and processing transmissions received from the NT-TRP 172 via the backhaul. Processing operations related to preparing to send downlink transmissions or backhaul transmissions may include operations such as encoding, modulation, precoding (e.g., MIMO precoding), transmit beamforming, and generating symbols for transmission. Processing operations related to processing received transmissions in the uplink or on the backhaul may include operations such as receive beamforming, demodulation, and decoding received symbols. The processor 260 may also perform operations related to network access (e.g., initial access) and / or downlink synchronization, such as generating the content of a synchronization signal block (SSB), generating system information, and the like. In some embodiments, the processor 260 also generates a beam direction indication, such as a BAI, that the scheduler 253 may schedule for transmission. The processor 260 may perform other network-side processing operations described herein, such as determining the location of the ED 110, determining the location at which the NT-TRP 172 is deployed, and the like. In some embodiments, the processor 260 may generate signaling to configure one or more parameters of the ED 110 and / or one or more parameters of the NT-TRP 172, and the like. Any signaling generated by the processor 260 is sent by the transmitter 252. It should be noted that the "signaling" used herein may alternatively be referred to as control signaling. Dynamic signaling may be sent in a control channel such as a physical downlink control channel (PDCCH), while static or semi-static higher layer signaling may be included in a data packet sent in a data channel such as a physical downlink shared channel (PDSCH).

[0075] The scheduler 253 can be coupled to the processor 260. The scheduler 253 can be included in the T-TRP 170, or it can work separately from the T-TRP 170. The scheduler 253 can schedule uplink transmissions, downlink transmissions, and / or backhaul transmissions, including issuing scheduling grants and / or configuring scheduling-free ("configuration grants") resources. The T-TRP 170 also includes a memory 258 for storing information and data. The memory 258 stores instructions and data used, generated, or collected by the T-TRP 170. For example, the memory 258 can store software instructions or modules that are used to implement some or all of the functions and / or embodiments described herein and are executed by the processor 260.

[0076] The processor 260 may be part of the transmitter 252 and / or part of the receiver 254, but is not shown. In addition, the processor 260 may implement the scheduler 253, but is not shown. The memory 258 may be part of the processor 260, but is not shown.

[0077] The processor 260, the scheduler 253, the processing components in the transmitter 252, and the processing components in the receiver 254 may be implemented by the same or different one or more processors, which are used to execute instructions stored in a memory (e.g., the memory 258). Alternatively, part or all of the processor 260, the scheduler 253, the processing components in the transmitter 252, and the processing components in the receiver 254 may be implemented using a dedicated circuit such as an FPGA, a GPU, or an ASIC.

[0078] Although the NT-TRP 172 is shown as a drone, this is only an example. The NT-TRP 172 can be implemented using any suitable non-ground form. In addition, the NT-TRP 172 may use other names such as non-ground nodes, non-ground network devices, or non-ground base stations in some implementations. The NT-TRP 172 includes a transmitter 272 and a receiver 274 coupled to one or more antennas 280. Only one antenna 280 is shown. One, part, or all of the antennas can be panels. The transmitter 272 and the receiver 274 can be integrated into a transceiver. The NT-TRP 172 also includes a processor 276 for performing operations related to: preparing downlink transmissions sent to the ED 110, processing uplink transmissions received from the ED 110, preparing backhaul transmissions sent to the T-TRP 170, and processing transmissions received from the T-TRP 170 via the backhaul. Processing operations associated with preparing to transmit a downlink transmission or a backhaul transmission may include operations such as encoding, modulation, precoding (e.g., MIMO precoding), transmit beamforming, and generating symbols for transmission. Processing operations associated with processing received transmissions in the uplink or on the backhaul may include operations such as receive beamforming, demodulation, and decoding of received symbols. In some embodiments, the processor 276 implements transmit beamforming and / or receive beamforming based on beam direction information (e.g., BAI) received from the T-TRP 170. In some embodiments, the processor 276 may generate signaling to configure one or more parameters of the ED 110, etc. In some embodiments, the NT-TRP 172 implements physical layer processing but does not implement higher-level functions, such as functions in the medium access control (MAC) layer or the radio link control (RLC) layer. Since this is just an example, in addition to physical layer processing, the NT-TRP 172 may generally implement higher-level functions.

[0079] NT-TRP 172 also includes a memory 278 for storing information and data. Processor 276 may be part of transmitter 272 and / or part of receiver 274, but is not shown. Memory 278 may be part of processor 276, but is not shown.

[0080] The processor 276, the processing components in the transmitter 272, and the processing components in the receiver 274 may be implemented by the same or different one or more processors, which are used to execute instructions stored in a memory (e.g., the memory 278). Alternatively, some or all of the processor 276, the processing components in the transmitter 272, and the processing components in the receiver 274 may be implemented using a dedicated circuit such as a programmed FPGA, GPU, or ASIC. In some embodiments, the NT-TRP 172 may actually be a plurality of NT-TRPs that operate together to serve the ED 110 through coordinated multi-point transmission or the like.

[0081] It should be noted that "TRP" as used herein may refer to T-TRP or NT-TRP.

[0082] The T-TRP 170, NT-TRP 172, and / or ED 110 may include other components, but these components are omitted for clarity.

[0083] One or more steps of the exemplary methods provided herein may be performed by Figure 4 etc. and executed by the corresponding units or modules provided. Figure 4 Exemplary units or modules in a device (e.g., in ED 110, in T-TRP 170, or in NT-TRP 172) are shown. For example, an operation may be controlled by an operating system module. As another example, a signal may be sent by a sending unit or a sending module. A signal may be received by a receiving unit or a receiving module. A signal may be processed by a processing unit or a processing module. Some operations / steps may be performed by an artificial intelligence (AI) module or a machine learning (ML) module. The corresponding units or modules may be implemented using hardware, one or more components or devices that execute software, or a combination thereof. For example, one or more of these units or modules may be a programmed integrated circuit such as an FPGA, GPU, or ASIC. It should be understood that if these modules are implemented using software for execution by a processor or the like, these modules may be retrieved by the processor in whole or in part as needed, retrieved individually or collectively for processing, retrieved in one or more instances, and these modules themselves may include instructions for further deployment and instantiation.

[0084] Other details about ED 110, T-TRP 170 and NT-TRP 172 are known to those skilled in the art. Therefore, these details are omitted here.

[0085] Some embodiments herein refer to control information. Control information may sometimes be referred to as control signaling or signaling. In some cases, control information may be transmitted dynamically, for example, dynamically transmitted in a physical layer control channel such as a physical uplink control channel (PUCCH) or a physical downlink control channel (PDCCH). An example of control information indicated dynamically is information sent in physical layer control signaling, for example, uplink control information (UCI) sent in PUCCH or downlink control information (DCI) sent in PDCCH. A dynamic indication may be an indication in a low layer, for example, a physical layer / layer 1 signaling, rather than an indication in a high layer (for example, not an indication in RRC signaling or in a MAC control element (CE)). A semi-static indication may be an indication in semi-static signaling. Semi-static signaling used herein may refer to non-dynamic signaling, for example, high layer signaling (for example, RRC signaling) and / or MAC CE. Dynamic signaling used herein may refer to dynamic signaling, for example, physical layer control signaling sent in the physical layer, for example, DCI sent in the PDCCH or UCI sent in the PUCCH.

[0086] Some embodiments herein refer to channel measurement. In wireless communication, a signal for measuring and feeding back measurement results may be transmitted. For example, the TRP may send a reference signal or a synchronization signal to the UE. An example of a reference signal is a channel state information (CSI) reference signal (CSI reference signal, CSI-RS). An example of a synchronization signal is a primary synchronization signal (PSS) and / or a secondary synchronization signal (SSS). The UE may perform measurements using the reference signal and / or the synchronization signal to obtain measurement results. The measurement result may be a channel measurement result (e.g., of channel quality). Examples of measurements that may be performed include: measuring CSI, for example, information related to scattering, fading, power attenuation and / or signal-to-noise ratio (SNR) in the channel; and / or measuring signal-to-interference-plus-noise ratio (SINR), sometimes referred to as signal-to-noise-plus-interference ratio (SNIR); and / or measuring reference signal received power (RSRP); and / or measuring reference signal received quality (RSRQ); and / or measuring channel quality to obtain a channel quality indicator (CQI), etc. Performing measurements on a received signal may include extracting waveform parameters from the signal, such as (but not limited to), amplitude, frequency, noise and / or timing of the waveform. The result may be a measurement result. The result of the measurement is called a measurement result, for example, the measurement result may be a measured SNR, SINR, RRSP and / or RSRQ. The UE may then send a measurement report back to the TRP. The measurement report may report part or all of the measurement results. The network may use the measurement results to perform link adaptation, radio resource management (RRM), etc. In addition to the measurement report, other content related to the measurement results may also be sent back to the TRP. For example, the UE may send an indication of a codebook and / or rank indication for the TRP to use for precoding. In another example, the UE may perform these inter-UE or inter-layer interference measurements and feedback the information in the measurement report. In another example, sensing may be performed and the sensing results may be reported.

[0087] The feedback is not necessarily an explicit indication of the channel quality, but may also be content selected or derived based on the measurement results, for example, an indication of the MCS, an indication of the codebook used for precoding and / or a rank indication, etc.

[0088] Therefore, in operation, many different information can be fed back in signaling based on the measurement of the received signal. For example, information fed back from one device to another device may include CSI, CQI, SNR, SINR, RRSP, RSRQ, codebook / rank indication for precoding, indication of MCS, etc. Any of these information can be regarded as information related to channel measurement. In some embodiments of this document, CQI is taken as an example, but the information related to channel measurement is not limited to CQI.

[0089] Embodiments are not limited to uplink communications and / or downlink communications.In general, two devices may communicate wirelessly with each other. Figure 5 Two devices for wireless communication provided by an embodiment of the present invention are shown. In order to more easily distinguish between the two devices, one is called device 302 and the other is called device 312. Device 302 can be a UE. Device 312 can be a network device, such as a TRP. However, this is not necessary. For example, device 302 can be a UE or a network device, and device 312 can be a UE or a network device. The terms "device" 302 and "device" 312 are simply used to more easily distinguish between the two entities. They can be the same type of entity, for example, device 302 and device 312 can both be UEs, or device 302 and device 312 can both be network devices (e.g., base stations or other TRPs), but generally speaking, this is not necessary.

[0090] In some embodiments, it is assumed that apparatus 302 is a device that sends information related to channel measurements performed by apparatus 302 to device 312. It is assumed that apparatus 312 is a device that sends control information to apparatus 302 to schedule transmissions with apparatus 302, wherein the control information allocates resources based on the information related to channel measurements performed by apparatus 302.

[0091] Device 312 includes a transmitter 314 and a receiver 316, both of which can be integrated as a transceiver. Transmitter 314 and receiver 316 are coupled to one or more antennas 313. Only one antenna 313 is shown. One, part or all of the antennas can be panels instead. Device 312 also includes a processor 318 to directly perform (or control device 312 to perform) the operation of device 312 described herein. Processor 318 can be part of transmitter 314 and / or part of receiver 316, but is not shown. Device 312 also includes a memory 320 for storing information and data. Device 312 also includes an analog-to-digital converter (ADC) 342 and a digital-to-analog converter (DAC) 344 for converting between analog signals and digital signals. ADC 342 can be used to convert an analog input voltage or current into a digital output value (e.g., digital) indicating the magnitude of the input voltage or current. DAC 344 can be used to convert a digital input value into an analog output voltage or current. The magnitude of the analog output voltage or current may be proportional to the digital input value, thereby indicating the digital input value.

[0092] The processor 318, ADC 342 and / or DAC 344, and part or all of the processing components in the transmitter 314 and the processing components in the receiver 316 can be implemented by the same or different one or more processors, which are used to execute instructions stored in a memory (e.g., memory 320). Alternatively, the processor 318, ADC 342, DAC 344 and / or part or all of the processing components in the transmitter 314 and / or the processing components in the receiver 316 can be implemented using a programmed FPGA, GPU or ASIC or other dedicated circuit. For example, ADC 342 and DAC 344 can be implemented by a dedicated integrated circuit (IC) chip (e.g., a microchip dedicated to performing conversion between analog and digital). The chip can be controlled by a processor (e.g., processor 318).

[0093] In some embodiments, device 312 may be a TRP. If device 312 is a T-TRP 170, processor 318 may be or include processor 260, processor 318 may implement scheduler 253, transmitter 314 may be or include transmitter 252, receiver 316 may be or include receiver 254, and memory 320 may be or include memory 258. If device 312 is an NT-TRP 172, processor 318 may be or include processor 276, transmitter 314 may be or include transmitter 272, receiver 316 may be or include receiver 274, and memory 320 may be or include memory 278.

[0094] The device 302 includes a transmitter 304 and a receiver 306, both of which can be integrated into a transceiver. The transmitter 304 and the receiver 306 are coupled to one or more antennas 303. Only one antenna 303 is shown. One, part or all of the antennas can be panels instead. The device 302 also includes a processor 308 to directly perform (or control the device 302 to perform) the operations of the processor 308 described herein. The processor 308 can be a part of the transmitter 304 and / or a part of the receiver 306, but is not shown. The device 302 also includes a memory 310 for storing information and data. The device 302 also includes an analog-to-digital converter (ADC) 332 and a digital-to-analog converter (DAC) 334 for converting between analog signals and digital signals. The ADC 332 can be used to convert an analog input voltage or current into a digital output value (e.g., digital) indicating the magnitude of the input voltage or current. The DAC 334 can be used to convert a digital input value into an analog output voltage or current. The magnitude of the analog output voltage or current may be proportional to the digital input value, thereby indicating the digital input value.

[0095] The processor 308, ADC 332 and / or DAC 334 and part or all of the processing components in the transmitter 304 and / or the processing components in the receiver 306 can be implemented by the same or different one or more processors, which are used to execute instructions stored in a memory (e.g., memory 310). Alternatively, the processor 308, ADC 332, DAC 334 and / or part or all of the processing components in the transmitter 304 and / or the processing components in the receiver 306 can be implemented using a programmed FPGA, GPU or ASIC or other dedicated circuit. For example, ADC 332 and DAC 334 can be implemented by a dedicated integrated circuit (IC) chip (e.g., a microchip dedicated to performing conversion between analog and digital). The chip can be controlled by a processor (e.g., processor 308).

[0096] If the apparatus 302 is a UE, such as the ED 110 , the processor 308 may be or include the processor 210 , the transmitter 304 may be or include the transmitter 201 , the receiver 306 may be or include the receiver 203 , and the memory 310 may be or include the memory 208 .

[0097] The device 312 and the apparatus 302 may include other components, but these components are omitted for clarity.

[0098] Various aspects of the present invention provide technical solutions that can solve the above-mentioned problems, for example, specific methods and devices for adjusting the configuration for converting between analog signals and digital signals. A device (such as but not limited to a transmit-and-receive point (TRP) (e.g., a base station)) can be configured with one or more configurations for converting between analog signals and digital signals in a device (such as but not limited to user equipment (UE)).

[0099] Each configuration may be associated with at least one of a bit resolution used by the apparatus when converting between analog signals and digital signals, a sampling rate used by the apparatus, or a combination of a bit resolution and a sampling rate used by the apparatus. Each configuration may be associated with information related to channel measurements performed by the apparatus. For example, each configuration may be associated with a corresponding channel quality indicator (CQI) table. The apparatus may send information related to channel measurements to the device, for example, including information in one or more CQI tables associated with one or more configurations. Each configuration may be associated with a modulation and coding scheme (MCS) value. The MCS value may be selected from an MCS table that is associated with a reference configuration used to convert between analog signals and digital signals in the apparatus.

[0100] The device may configure a mapping between each of the plurality of configurations and at least one of a corresponding bit resolution, a corresponding sampling rate, or a corresponding combination of bit resolution and sampling rate. Part of the mapping may be predefined or preconfigured by the device. The device may select one of the plurality of configurations for converting between analog signals and digital signals in the apparatus and indicate the configuration as the operational configuration.

[0101] In some embodiments, the device may operate on the same operating configuration for analog-to-digital signal conversion and for digital-to-analog signal conversion. In some embodiments, the device may operate on different operating configurations for converting analog signals to digital signals and converting digital signals to analog signals. In the present invention, for simplicity, the following expressions are generally used, for example, a configuration for converting between analog signals and digital signals. It is readily understood by those skilled in the art that the configuration for converting between analog signals and digital signals may include a configuration for analog-to-digital signal conversion and / or a configuration for digital-to-analog signal conversion. The configuration for analog-to-digital signal conversion may be the same as or different from the configuration for digital-to-analog signal conversion. The total number of configurations for analog-to-digital signal conversion may be the same as or different from the total number of configurations for digital-to-analog signal conversion.

[0102] The device may perform a configuration change or configuration adjustment explicitly or implicitly. The device may change the configuration currently running the device according to the information indicating the configuration change. The device may receive information indicating the configuration change from the device. The information indicating the configuration change may be an explicit indication that the device performs a configuration change. For example, the information may indicate the operating configuration that the device is to run, which may be used as an explicit indication that the device switches to a new operating configuration. The information indicating the configuration change may be an implicit indication that the device performs a configuration change. In this case, the information indicating the configuration change may include information related to at least one of the following: the power consumption mode of the device, the type of the device, the scheduling MCS, the scheduling resource blocks (e.g., the number of resource blocks), the scheduling transmission blocks (e.g., the transmission block size), the number of transmission blocks, the number of layers used for data transmission, or the carrier frequency range.

[0103] The device may perform a configuration change after a configuration change delay. The configuration change delay may be determined based on at least one of the following: the device's ability to convert between analog and digital signals, a bit resolution associated with a previous configuration, a bit resolution associated with an operating configuration, a spectrum range, a system parameter (numerology) of an active bandwidth part (BWP), a number of transmit (Tx) antennas, a number of receive (Rx) antennas, a number of radio frequency (RF) chains, or a carrier bandwidth or an active BWP bandwidth.

[0104] The configuration (eg, operating configuration) for converting between analog and digital signals may be specific to a device, a carrier or spectrum range, a BWP, an RF chain, a Tx antenna, a Tx antenna group, an Rx antenna, or an Rx antenna group.

[0105] The device (e.g., TRP) may be configured with one or more device configurations for converting between analog signals and digital signals in the device. Each device configuration may be associated with at least one of the following: a bit resolution used by the device when converting between analog signals and digital signals, a sampling rate used by the device, or a combination of a bit resolution and a sampling rate used by the device. Some technical features associated with these device configurations may be similar to technical features associated with configurations for converting between analog signals and digital signals in the apparatus.

[0106] According to some embodiments, there are one or more configurations for converting between analog signals and digital signals in the device (e.g., UE). The device may operate (e.g., perform channel measurement, report channel measurement feedback, decode, encode) and convert analog signals and digital signals according to one of these configurations. The configuration currently operated by the device may be referred to as an operating configuration (for converting between analog signals and digital signals in the device).

[0107] As described above, the resolution of an analog digital converter (ADC) and the resolution of a digital analog converter (DAC) can be expressed using the number of bits (e.g., N bits) used to convert between analog samples and digital samples. Each configuration for converting between analog signals and digital signals can be associated with a corresponding bit resolution (e.g., N bits) used by the device when converting between analog signals and digital signals, a corresponding sampling rate (e.g., Fs) used by the device, and / or a corresponding combination of bit resolution and sampling rate used by the device. Therefore, different configurations can have different bit resolutions, different sampling rates, and / or different combinations of bit resolution and sampling rate.

[0108] A device (e.g., a TRP) may be configured to perform one or more configurations for converting between analog and digital signals in an apparatus, as described below or elsewhere herein.

[0109] A device (e.g., UE) may report capabilities of the device related to analog-to-digital signal conversion. For example, the device may send information related to the device's capabilities for converting between analog signals and digital signals to the device. The information related to the device's capabilities for converting between analog signals and digital signals may include at least one of the following:

[0110] The bit resolution supported by the device when converting between analog and digital signals (e.g., a list of N values: {N 1 ,N 2 ,N 3 ,…,N k});

[0111] The sampling rates supported by the device when converting between analog and digital signals (e.g., a list of Fs values: {Fs 1 ,Fs 2 ,Fs 3 ,…,Fs k});

[0112] The bit resolution and sampling rate combinations supported by the device when converting between analog and digital signals (e.g., a list of (N, Fs) values: {(N 1 ,Fs 1 ),(N 2 ,Fs 2 ),(N 3 ,Fs 3 ),…,(N k ,Fs k )}).

[0113] After receiving a report / information related to the ability of the device to convert between analog signals and digital signals, the device can be configured to perform one or more configurations for converting between analog signals and digital signals in the device. In some embodiments, the device can directly configure the corresponding bit resolution (i.e., N) and / or the corresponding sampling rate (i.e., Fs) for converting between analog signals and digital signals in the device. In other words, the device can directly configure the value of N and / or Fs to some or all of the configurations in a variety of configurations. In some embodiments, the device can configure these configurations with a mapping between at least one of the corresponding bit resolutions, corresponding sampling rates, or corresponding combinations of bit resolutions and sampling rates. The device can configure an index to the configuration for converting between analog signals and digital signals in the device. For example, two different configurations can be configured to convert between analog signals and digital signals in the device. One configuration can be configured to low resolution (or low bit resolution), and another configuration can be configured to high resolution (or high bit resolution). For low bit resolution, the device uses fewer bits (e.g., N is smaller), a lower sampling rate (e.g., Fs value is smaller) and / or a smaller output value of the function f(N, Fs) (e.g., f(N, Fs) = 6.02*N + 1.76dB + 10*lg(Fs / 2BW)) to convert between analog signals and digital signals, where N is the number of bits indicating the ADC / DAC resolution, dB is the decibel indicating the ratio difference between two signals (e.g., the difference in power, voltage or signal strength between two points in a cable or network), Fs is the sampling rate, and BW is the signal bandwidth. For high bit resolution, the device uses more bits (e.g., N is larger), a higher sampling rate (e.g., Fs value is larger) and / or a larger output value of the function f(N, Fs).

[0114] One of the multiple configurations may be configured by the device as an operational configuration, which is the configuration in which the device is to operate. For example, the device may select one of the multiple configurations for converting between analog signals and digital signals in the device, and indicate this configuration as the operational configuration.

[0115] In some embodiments, at least one of the partial mappings between these configurations and the corresponding bit resolution, the corresponding sampling rate, or the corresponding combination of bit resolution and sampling rate may be predefined or preconfigured by the device. Some examples of these preconfigured mappings are provided below in Tables 1, 2, and 3.

[0121] Table 3 Mapping between configuration and (N, Fs)

[0122] In some embodiments, each configuration for converting between analog signals and digital signals may be associated with information related to channel measurements performed by the device. The information related to the channel measurements may include information in one or more channel quality indicator (CQI) tables. Each CQI table may be associated with at least one configuration for converting between analog signals and digital signals in the device. In other words, multiple configurations for converting between analog signals and digital signals in the device may be associated with the same CQI table. The mapping between these configurations and one or more CQI tables may be predefined or preconfigured by the device (e.g., TRP), etc.

[0123] Two exemplary CQI tables are provided below in Table 4 and Table 5A. Table 4 shows an exemplary CQI table associated with a configuration for high bit resolution, and Table 5A shows an exemplary CQI table associated with a configuration for low bit resolution.

[0126] Table 4 CQI table associated with configuration for high bit resolution

[0127]

[0128] Table 5A CQI table associated with configuration for low bit resolution

[0129] The CQI table can be generated based on other CQI tables. For example, the above Table 5A can be generated based on the above Table 4. Specifically, as shown above, one or more entries can be added to Table 4 on the less efficient side (for example, the newly added entries where CQI index = 1, 2 in Table 5A) and one or more entries can be removed from Table 4 on the more efficient side (for example, the 64 Quadrature Amplitude Modulation (QAM) entries where CQI index = 10 to 15 in Table 4). The following Table 5B shows the difference between Table 4 and Table 5A, thereby showing how Table 5A is generated based on Table 4. In the following Table 5B, double brackets and strikethroughs indicate deleted or canceled values, and underlines indicate added or updated values.

[0130]

[0131]

[0132] Table 5B CQI table associated with configuration for low bit resolution

[0133] Each CQI table may be a corresponding different table including different available modulation orders, different coding rates, or both, for example, as shown in Table 4 and Table 5 above.

[0134] In some embodiments, some or all of the CQI tables associated with these configurations may be derived from the main CQI table and may be a subset of the main CQI table, such as Figure 6 Reference Figure 6 , CQI table 610 is a subset of main CQI table 600 and is associated with a configuration for low bit resolution. CQI table 620 is another subset of main CQI table 600 and is associated with a configuration for high bit resolution. The size of the main CQI table can be larger or smaller than Figure 6 Main CQI table 600 is shown. Providing multiple CQI tables (each CQI table corresponding to a corresponding different bit resolution and / or sampling rate) can reduce the number of bits used to indicate CQI values ​​compared to providing a large CQI table with a wide distribution of CQI values ​​covering all bit resolutions and / or sampling rates.

[0135] The apparatus may send information related to channel measurements associated with the operational configuration to the device. The information sent to the device may be information in a CQI table associated with the operational configuration. The information in the CQI table associated with the operational configuration may be referred to as one or more CQI values ​​and include information indicating a CQI index, modulation, coding rate, (spectral) efficiency, and / or any combination thereof. The CQI value may be derived or selected by the apparatus from a CQI table associated with the operational configuration.

[0136] In some embodiments, the device may send a CQI value (e.g., a CQI index) in a CQI table associated with an operating configuration to the device. The CQI value to be sent to the device may be determined or calculated by the device using the operating configuration. For example, the device calculates the CQI value to be sent based on the bit resolution, sampling rate, and / or a combination of bit resolution and sampling rate associated with the operating configuration. For example, the device may receive a wireless reference signal and convert the reference signal into a digital reference signal using the operating configuration (e.g., using an ADC with a bit resolution and / or sampling rate associated with the operating configuration). The device may then perform channel measurements using the digital reference signal to obtain measurement results. The device may then map the measurement results to the CQI values ​​in the CQI table associated with the operating configuration. Thereafter, the device may send the CQI value to the device.

[0137] In some embodiments, the apparatus may send to the device multiple CQI values ​​(e.g., multiple CQI indexes) from multiple CQI tables associated with multiple configurations for converting between analog signals and digital signals. In addition to the CQI values ​​associated with the operating configuration, the apparatus may also send one or more CQI values ​​associated with other configurations for converting between analog signals and digital signals. When the apparatus and / or device performs a configuration change (e.g., switches from one configuration to another), the device (e.g., TRP) may use other CQI values ​​associated with other configurations to allocate resources and schedule transmissions with the apparatus.

[0138] In some embodiments, the apparatus may perform multiple channel measurements to obtain multiple CQI values, wherein each channel measurement is performed according to a different (corresponding) configuration for converting between analog signals and digital signals. Each of the multiple CQI values ​​obtained by the multiple channel measurements may be associated with a corresponding configuration for converting between analog signals and digital signals. Then, in a similar manner as described above, the apparatus may send multiple CQI values ​​to the device, so that when the apparatus and / or the device performs a configuration change (e.g., switches from one configuration to another), the device may use the multiple CQI values ​​to allocate resources and schedule transmissions with the apparatus.

[0139] After sending information related to channel measurements performed by the apparatus (e.g., CQI values), the device may send control information for scheduling transmissions with the apparatus, wherein the control information allocates resources based on the information related to the channel measurements. The device may also send a modulation and coding scheme (MCS) value (e.g., modulation order, coding rate) to the apparatus as part of the control information for scheduling. The MCS value may be associated with the information related to the channel measurements (e.g., the MCS value may be based on the CQI value received from the apparatus).

[0140] Information related to the channel measurement performed by the apparatus (e.g., a CQI value in a CQI table) may be related to the downlink channel quality and sent from the apparatus to the device. For example, the apparatus performs channel measurement of a downlink channel using a downlink reference signal and sends a CQI value indicating the downlink channel quality to the device. However, the device may not use one or more MCS values ​​associated with the downlink channel quality received from the apparatus for downlink transmission. Therefore, when the device schedules a downlink transmission, the device may need to send one or more MCS values ​​to be used for the downlink transmission to the device. For example, the device may send an MCS index indicating the MCS value to be used for the downlink transmission. The MCS index may be sent as part of downlink control information (DCI) for scheduling downlink transmission. For DCI scheduling, the apparatus may use an MCS table associated with an operating configuration. The device may need to know which MCS table is associated with the operating configuration so that the MCS index received from the device can be used to obtain one or more correct MCS values. This is because there may be multiple MCS tables, each of which is associated with a respective (different) configuration for converting between analog and digital signals in the device. The same applies to scheduling uplink transmissions, for example, although the channel measurements performed by the device may be based on downlink signals (e.g., downlink reference signals), it may be assumed that the uplink channel quality is similar to the downlink channel quality, so that when the device schedules an uplink transmission for the device, the device may use the channel measurements to determine the MCS value to be sent to the device.

[0141] In some embodiments, each configuration for converting between analog signals and digital signals may be associated with information related to a modulation and coding scheme (MCS) value. The MCS value may be selected or derived from a modulation and coding scheme (MCS) table. Each MCS table may be associated with at least one configuration for converting between analog signals and digital signals in the device. In other words, multiple configurations for converting between analog signals and digital signals in the device may be associated with the same MCS table. The mapping between these configurations and one or more MCS tables may be predefined or preconfigured by the device (e.g., TRP), etc.

[0142] Some exemplary MCS tables are provided below in Tables 6A to 7B. Tables 6A and 6B show exemplary MCS tables associated with configurations for high bit resolution and may be used for transmissions on a physical downlink shared channel (PDSCH) and / or a physical uplink shared channel (PUSCH). Tables 7A and 7B show exemplary MCS tables associated with configurations for low bit resolution and may be used for transmissions on PDSCH and / or PUSCH.

[0151]

[0152]

[0153] Table 7B MCS table associated with configuration for low bit resolution

[0154] As shown in Table 6A and Table 6B above, the MCS table associated with the configuration for high bit resolution may include entries with modulation orders up to 64QAM, similar to the modulation orders in the new radio (NR). These MCS tables may not include entries with modulation orders of binary phase shift keying (BPSK). In general, the entries in the MCS table associated with the configuration for high bit resolution have larger spectral efficiency values. On the other hand, as shown in Table 7A and Table 7B above, the MCS table associated with the configuration for low bit resolution may include entries with modulation orders up to 16QAM. There may be some entries with modulation orders of BPSK. In general, the entries in the MCS table associated with the configuration for low bit resolution have smaller spectral efficiency values.

[0155] Each MCS table may be a corresponding different table including different available modulation orders, different coding rates, or both, for example, as shown in Tables 6A to 7B above. In some embodiments, the different available modulation orders may include some or all of BPSK, Quadrature Phase-Shift Keying (QPSK), 16QAM, and 64QAM.

[0156] In some embodiments, some or all of the MCS tables associated with these configurations may be derived from the main MCS table and may be a subset of the main MCS table, such as Figure 7 Reference Figure 7 , MCS table 710 is a subset of main MCS table 700 and is associated with a configuration for low bit resolution. MCS table 720 is another subset of main MCS table 700 and is associated with a configuration for high bit resolution. The size of the main MCS table can be larger or smaller than Figure 7 The main MCS table 700 is shown. Providing multiple MCS tables (each MCS table corresponding to a corresponding different bit resolution and / or sampling rate) can reduce the number of bits used to indicate MCS values ​​compared to providing a large MCS table with a wide distribution of MCS values ​​covering all bit resolutions and / or sampling rates.

[0157] The device may send a modulation and coding scheme (MCS) value associated with a reference configuration for converting between analog signals and digital signals in the device to the device. The reference configuration may be an operating configuration or another configuration different from the operating configuration. The MCS value sent to the device may be selected or derived from an MCS table associated with the reference configuration. The MCS value may be selected by the device. The MCS table associated with the reference configuration may be one of a plurality of MCS tables, each of which may be associated with at least one configuration for converting between analog signals and digital signals in the device. The MCS value may include information indicating an MCS index, a modulation order, a coding rate, a spectral efficiency, and / or any combination thereof.

[0158] When the apparatus operates on a low bit resolution configuration for digital-to-analog signal conversion, the quality of the uplink signal sent by the apparatus is low, and thus the device may schedule uplink transmissions associated with a smaller MCS value. If the apparatus operates on a high bit resolution configuration for digital-to-analog signal conversion, the quality of the uplink signal sent by the apparatus is high, and thus the device may schedule uplink transmissions associated with a larger MCS value.

[0159] As described above, in some embodiments, the device can operate on the same operating configuration for analog-to-digital signal conversion and for digital-to-analog signal conversion. However, in some embodiments, the device can operate on different operating configurations for analog-to-digital signal conversion and for digital-to-analog signal conversion. For example, the device wishes to receive a downlink signal with a higher bit resolution, but wishes to send a signal with a lower bit resolution to save power. The total number of configurations for analog-to-digital signal conversion may be the same as or different from the total number of configurations for digital-to-analog signal conversion.

[0160] In some embodiments where the device uses the same configuration for analog-to-digital signal conversion and digital-to-analog signal conversion, the reference configuration for converting between analog signals and digital signals in the device may be the operating configuration that the device will operate in. In other words, if the device uses the same bit resolution and / or the same sampling rate for analog-to-digital signal conversion and digital-to-analog signal conversion, the reference configuration may be the operating configuration that the device will operate in.

[0161] In some embodiments where the apparatus may use different configurations for analog-to-digital signal conversion and digital-to-analog signal conversion, there are multiple methods for determining the reference mode, as described below or elsewhere in the present disclosure.

[0162] In some embodiments, the reference configuration may be a configuration associated with a lower bit resolution or sampling rate in the operating configuration for analog-to-digital signal conversion and the operating configuration for digital-to-analog signal conversion. For example, when the operating configuration for analog-to-digital signal conversion is associated with N1 bit resolution and the operating configuration for digital-to-analog signal conversion is associated with N2 bit resolution, the reference configuration may be associated with N3 bit resolution, where N3 is the smaller of N1 and N2. The device may use the MCS table associated with the reference configuration for uplink scheduling and downlink scheduling. Therefore, the reference configuration may be different from at least one operating configuration. For example, the bit resolution and / or sampling rate associated with the reference configuration may be less than or greater than the bit resolution and / or sampling rate associated with at least one operating configuration.

[0163] In some embodiments, two different reference configurations may be used. For example, when the operation configuration for analog-to-digital signal conversion is associated with N1 bit resolution and the operation configuration for digital-to-analog signal conversion is associated with N2 bit resolution, the device may use the MCS table associated with the N1 bit resolution configuration (i.e., the configuration associated with N1 bit resolution) for downlink scheduling, and use the MCS table associated with the N2 bit resolution configuration (i.e., the configuration associated with N2 bit resolution) for uplink scheduling. It should be noted that the device may convert analog signals into digital signals for downlink transmission, and convert digital signals into analog signals for uplink transmission.

[0164] According to some embodiments, there are one or more device configurations for converting between analog signals and digital signals in a device (e.g., a TRP). The device can operate and convert analog signals and digital signals according to one of these device configurations. The device configuration in which the device is to operate can be referred to as a device operating configuration (for converting between analog signals and digital signals in the device).

[0165] A device (e.g., a TRP) may be configured with one or more device configurations for converting between analog signals and digital signals at the device, as described below or elsewhere in the present invention.

[0166] In some embodiments, the device explicitly defines multiple device configurations for converting between analog signals and digital signals in the device. Each device configuration for converting between analog signals and digital signals in the device can be associated with a corresponding bit resolution (e.g., N bits) used by the device when converting between analog signals and digital signals, a corresponding sampling rate (e.g., Fs) used by the device, and / or a corresponding combination of bit resolution and sampling rate used by the device. Therefore, different device configurations can have different bit resolutions, different sampling rates, and / or different combinations of bit resolution and sampling rate.

[0167] In some embodiments, each device configuration for converting between analog signals and digital signals may be associated with one or more channel quality indicator (CQI) tables (i.e., tables of CQI values) or one or more channel state information (CSI) tables (i.e., tables of CSI values). Each CQI table and / or each CSI table may be associated with at least one configuration for converting between analog signals and digital signals in the device. In other words, multiple configurations for converting between analog signals and digital signals in the device may be associated with the same CQI table and / or CSI table. The mapping between these configurations and one or more CQI tables / CSI tables may be predefined or preconfigured by the device (e.g., TRP).

[0168] In some embodiments, each device configuration for converting between analog signals and digital signals may be associated with one or more modulation and coding scheme (MCS) tables (i.e., tables of MCS values). Each MCS table may be associated with at least one configuration for converting between analog signals and digital signals in the device. In other words, multiple configurations for converting between analog signals and digital signals in the device may be associated with the same MCS table. The mapping between these configurations and one or more MCS tables may be predefined or preconfigured by the device (e.g., TRP), etc.

[0169] The device may send information indicating a device configuration for converting between analog signals and digital signals in the device to an apparatus (e.g., a UE). In some embodiments, the information indicating the device configuration may be an explicit indication of the device configuration. In some embodiments, the information indicating the device configuration may include at least one of the following: an indication of a CQI table and / or a CSI table associated with the corresponding device configuration, or an indication of an MCS table associated with the corresponding device configuration.

[0170] The device may send information indicating device configuration via broadcast signaling, radio resource control (RRC), medium access control (MAC) control element (MAC-CE), or downlink control information (DCI).

[0171] One of a plurality of device configurations may be configured by the device as an operational device configuration, which is a configuration in which the device is to operate. For example, the device may select one of the device configurations for converting between analog signals and digital signals in the device and indicate this configuration as the device operational configuration. Thus, like other device configurations, this device operational configuration is associated with a bit resolution (e.g., N bits) used by the device when converting between analog signals and digital signals, a sampling rate (e.g., Fs) used by the device, and / or a combination of a bit resolution and a sampling rate used by the device.

[0172] The device may send information indicating a device operation configuration for converting between analog signals and digital signals in the device to a device (e.g., UE). The information indicating the device operation configuration may include at least one of the following: an indication of a table of channel quality values ​​(e.g., a CQI table) associated with the device operation configuration, or an indication of an MCS table associated with the device operation configuration. In this way, the device may know which CQI table and / or MCS table is associated with the device operation configuration, so that the device may obtain a correct CQI value and / or MCS value from a correct CQI table and / or MCS table associated with the device operation configuration.

[0173] In some embodiments, the device does not explicitly define a device configuration for converting between analog signals and digital signals in the device. In view of the presence of multiple CQI tables and / or multiple MCS tables, but no explicitly defined device configuration, the device may send an indication to the device of which CQI table and / or which MCS table the device is to use. In this way, the device can obtain the correct CQI value and / or MCS value from the correct CQI table and / or MCS table. For example, when the device is running on a low-bit resolution device configuration for analog-to-digital signal conversion, the device sends an indication to the device that the device is to use a low-bit resolution CQI table and / or a low-bit resolution MCS table to transmit to the device. In the MCS table for low bit resolution, the maximum supported modulation order may be 16QAM, while in the MCS table for high bit resolution, the maximum supported modulation order may be 64QAM.

[0174] It should be noted that switching the device configuration for converting between analog signals and digital signals in the device (performing a device configuration change) can be implemented inside the device, and the device is notified only when the switching causes the device to use a different CQI table and / or MCS table. In this case, the device may only be informed of switching to a different CQI table and / or MCS table. The reason for using a different CQI table and / or MCS table may not be informed.

[0175] In some embodiments, the device may perform a configuration change. The configuration change process may include deactivating a previous configuration for converting between analog signals and digital signals in the device, and activating a (new) operating configuration for converting between analog signals and digital signals in the device. The previous configuration may be the configuration that the device (currently) runs before the configuration change. In other words, the previous configuration may be the previous operating configuration for converting between analog signals and digital signals in the device. After the previous configuration is deactivated, the (new) operating configuration may be activated based on information indicating the operating configuration received from the device. If no configuration was previously configured (for example, when performing an initial configuration), there may be no deactivation step in the configuration change. In other words, if no configuration was previously configured, the previous configuration may be empty. In some embodiments, the configuration change process may include modifying the operating configuration that the device (currently) runs. For example, the bit resolution and / or sampling rate associated with the operating configuration may be changed by the configuration change process. In some embodiments, the configuration change process may include modifying other configurations (i.e., configurations that are not operating configurations) for converting between analog signals and digital signals in the device. In some embodiments, the configuration change process may include reconfiguring one or more configurations for converting between analog signals and digital signals in the device. The reconfiguration process may include a process similar to the radio resource control (RRC) reconfiguration process in the 3rd Generation Partnership Project (3GPP) new radio (NR) protocol.

[0176] As described above, one of the multiple configurations may be configured by the device as an operational configuration. The device may configure the operational configuration to the apparatus explicitly or implicitly. The device may send information to the apparatus indicating the (new) operational configuration that the apparatus will run when the configuration is changed. The information indicating the operational configuration may indicate the operational configuration explicitly or implicitly. The device may send information indicating the operational configuration upon request by the apparatus. After the apparatus receives (explicitly or implicitly) the information indicating the operational configuration, the apparatus may perform a configuration change according to the received (explicitly or implicitly) information indicating the operational configuration, which may include a deactivation process and / or an activation process as described above. In some cases, the apparatus may not perform a configuration change because the configuration currently running on the apparatus is the same as the configuration indicated in the received information.

[0177] In some embodiments, the device may send information indicating a (new) operating configuration to the apparatus, the information including an explicit indication of the (new) operating configuration that the apparatus is to run. The information including the explicit indication of the (new) operating configuration may be sent via broadcast signaling, a radio resource control (RRC), a medium access control (MAC) control element (MAC-CE), or downlink control information (DCI). Thus, depending on the scenario or implementation, the configuration change may be performed dynamically (e.g., via DCI) or semi-statically (e.g., via RRC signaling).

[0178] In some embodiments, the device may send information indicating an operational configuration to the apparatus, the information including an implicit indication of a (new) operational configuration that the apparatus is to run. Implicit indications of configuration changes are discussed further below and elsewhere in the present invention. Note that implicit indications may also be sent via broadcast signaling, radio resource control (RRC), a medium access control (MAC) control element (MAC-CE), or downlink control information (DCI).

[0179] The implicit indication of the (new) operating configuration may include information related to the power consumption mode of the device. The device may perform a configuration change based on the information related to the power consumption mode. The information related to the power consumption mode may indicate the (new) operating configuration that the device is to run, depending on the mapping between the configuration for converting between analog signals and digital signals in the device and the power consumption mode of the device. For example, when the device receives information that the device is to change to a power saving mode, the device may also perform a configuration change based on the mapping between these configurations and the power consumption mode, thereby switching to a configuration for low bit resolution. The mapping between these configurations and the power consumption mode of the device may be preconfigured or predetermined by the device. For example, a configuration for low bit resolution may be associated with a power saving mode, while a configuration for high bit resolution may be associated with a conventional power mode.

[0180] The implicit indication of the (new) operating configuration may include information related to the type of the device. The device may perform an initial configuration or a configuration change (e.g., switching configuration, modifying configuration, etc.) based on the information related to the type of the device. The information related to the type of the device may indicate the operating configuration that the device is to run, depending on the mapping between the configuration for converting between analog signals and digital signals in the device and the type of the device. The mapping between these configurations and the type of the device may be preconfigured or predetermined by the device. For example, a configuration for low bit resolution may be associated with a low-cost device, while a configuration for high bit resolution may be associated with a high-performance device. In some embodiments, since the capabilities of the device do not change, the device may only use information related to the type of the device when performing the (initial) configuration.

[0181] The implicit indication of the (new) operating configuration may include information related to the scheduled MCS used by the device (e.g., the MCS indicated in control information that schedules transmissions to and from the device). The information related to the scheduled MCS may indicate the (new) operating configuration that the device is to run, depending on the mapping between the configuration used to convert between analog signals and digital signals in the device and the scheduled MCS values. For example, when the device receives information related to the scheduled MCS index, the device may also perform a configuration change (e.g., switch to the (new) operating configuration) based on the mapping between these configurations and the scheduled MCS values. The mapping between these configurations and the scheduled MCS values ​​may be preconfigured or predetermined by the device. An exemplary mapping between the configuration used to convert between analog signals and digital signals and the scheduled MCS index is shown in Table 8 below.

[0184] As described above, a configuration for high bit resolution may be mapped to a high MCS index (eg, I MCS >Threshold_2), because a high MCS index indicates a high throughput requirement, and achieving high throughput requires a configuration for high bit resolution. A configuration for high bit resolution can also be mapped to a low or ultra-low MCS index (e.g., I MCS ≤Threshold_1) to improve the signal-to-noise ratio (SNR) performance. MCS indexes in other ranges (e.g., Threshold_1 MCS ​≤Threshold_2) can be mapped to a configuration configured through radio resource control (RRC) or a configuration for low bit resolution.

[0185] The implicit indication of the (new) operating configuration may include information related to the number of resource blocks. The information related to the number of resource blocks may (implicitly) indicate the (new) operating configuration that the device is to run, depending on the mapping between the configurations used for converting between analog signals and digital signals in the device and the number of resource blocks. For example, when the device receives information related to the number of scheduled resource blocks, the device may also perform a configuration change (e.g., switch to the (new) operating configuration) based on the mapping between these configurations and the number of scheduled resource blocks. The mapping between these configurations and the number of scheduled resource blocks may be preconfigured or predetermined by the device.

[0186] In some embodiments, the configuration for high bit resolution can be used for large scheduling bandwidth. When the number of scheduled resource blocks is greater than a certain threshold, the device can run on the configuration for high bit resolution. When the number of scheduled resource blocks is less than or equal to the threshold, the device can run on the configuration for low bit resolution. The mapping between the configuration for converting between analog signals and digital signals and the number of scheduled resource blocks can be configured as shown in Table 9A. The basic principle behind the mapping shown in Table 9A can be that the configuration for high bit resolution can be used for a larger scheduling bandwidth to increase throughput. The configuration for low bit resolution can be used for a smaller scheduling bandwidth and / or a smaller data packet.

[0188] Table 9A Mapping between configuration and scheduling resource blocks for conversion between analog and digital signals

[0189] On the other hand, in some embodiments, a configuration for high bit resolution may be used for a small scheduling bandwidth, while a configuration for low bit resolution may be used for a large scheduling bandwidth, as shown in Table 9B. The rationale behind the mapping shown in Table 9B may be that the device (e.g., TRP) may use more scheduled resource blocks to compensate for the SNR loss associated with the configuration for low bit resolution and achieve power saving.

[0191] Table 9B Mapping between configuration and scheduling resource blocks for conversion between analog and digital signals

[0192] The implicit indication of the (new) operating configuration may include information related to the transport block size. The device may perform a configuration change based on the information related to the transport block size. The information related to the transport block size may indicate the (new) operating configuration that the device is to run, depending on the mapping between the configuration for converting between analog signals and digital signals in the device and the transport block size. The mapping between these configurations and the transport block size may be preconfigured or predetermined by the device. For example, a configuration for low bit resolution may be associated with a transport block size less than or equal to a threshold to achieve power saving in the case of small data packets, while a configuration for high bit resolution may be associated with a transport block size greater than a threshold to achieve high throughput in the case of large data packets.

[0193] The implicit indication of the (new) operating configuration may include information related to the number of transport blocks. The device may perform a configuration change based on the information related to the number of transport blocks. The information related to the number of transport blocks may indicate the (new) operating configuration that the device is to run, depending on the mapping between the configuration for converting between analog signals and digital signals in the device and the number of transport blocks. The mapping between these configurations and the number of transport blocks may be preconfigured or predetermined by the device. For example, when only one transport block is scheduled, a configuration for low bit resolution or a configuration configured by RRC may be used, while when two or more transport blocks are scheduled, a configuration for high bit resolution may be used.

[0194] The implicit indication of the (new) operating configuration may include information related to the number of layers used for data transmission. The device may perform a configuration change based on the information related to the layer. The information related to the number of layers may indicate the (new) operating configuration that the device is to run, depending on the mapping between the configuration and the number of layers used for conversion between analog signals and digital signals in the device. The mapping between these configurations and the number of layers may be preconfigured or predetermined by the device. For example, when the number of scheduling layers is less than or equal to a threshold, a configuration for low bit resolution or a configuration configured by RRC may be used, and when the number of scheduling layers is greater than a threshold, a configuration for high bit resolution may be used. Table 10 below provides an example of a mapping between a configuration for conversion between analog signals and digital signals and the number of scheduling layers.

[0195]

[0196] Table 10 Mapping between configuration and scheduling layers for conversion between analog and digital signals

[0197] The implicit indication of the (new) operating configuration may include information related to the carrier frequency range. The information related to the number of layers may indicate the (new) operating configuration that the device is to run, depending on the mapping between the configuration for converting between analog signals and digital signals in the device and the carrier frequency range. The mapping between these configurations and the carrier frequency range may be preconfigured or predetermined by the device. For example, a configuration for low bit resolution or a configuration configured by RRC may be mapped to a high frequency band to achieve power saving, while a configuration for high bit resolution may be mapped to a low frequency band to meet throughput requirements.

[0198] Although the above only describes the information included in the implicit indication of the (new) operation configuration based on two configurations for converting between analog signals and digital signals (i.e., configurations for high bit resolution and low bit resolution), it should be noted that there may be more than two configurations for converting between analog signals and digital signals. For example, there may be three configurations for converting between analog signals and digital signals mapped to the number of scheduling layers, as shown in Table 11.

[0199]

[0200] Table 11 Mapping between configuration and scheduling layers for conversion between analog and digital signals

[0201] In some embodiments, some configurations (including operating configurations and / or reference configurations) for converting between analog signals and digital signals may be specific to a device, a carrier or spectrum range, a bandwidth part (BWP), a radio frequency (RF) chain, a transmit (Tx) antenna, a Tx antenna group, a receive (Rx) antenna, or an Rx antenna group.

[0202] For example, when a configuration for converting between analog signals and digital signals is configured for a device and the device uses multiple carriers (eg, in carrier aggregation), the configuration of each carrier may be the same.

[0203] For example, when the configuration for converting between analog signals and digital signals is configured for a carrier or a spectrum range (carrier-specific configuration or spectrum range-specific configuration), the device may configure these configurations for the device according to each carrier or each spectrum range. That is, different configurations may be configured for different carriers or different spectrum ranges.

[0204] For example, when configurations for converting between analog signals and digital signals are configured for bandwidth part (BWP), the apparatus may configure these configurations for the device according to each BWP, and configuration changes may be performed when switching BWPs.

[0205] For example, when the configuration for converting between analog signals and digital signals is configured for a radio frequency (RF) chain, an RF channel, or an RF link, the device can configure these configurations for the apparatus so that the configuration for low bit resolution is mapped to some RF chains to save power, while the configuration for high bit resolution is mapped to other RF chains to improve communication performance.

[0206] For example, the device may be configured with a configuration for performing conversion between analog signals and digital signals for a transmitting (Tx) antenna, a Tx antenna group, a receiving (Rx) antenna, or an Rx antenna group. If no configuration for performing conversion between analog signals and digital signals is configured, a predetermined default configuration (e.g., a configuration for high bit resolution) may be used.

[0207] As described above, in some embodiments, the device may send information indicating a configuration change based on a request from the apparatus. In other words, the device may approve a request from the apparatus to change an operational configuration for converting between analog signals and digital signals in the apparatus. The request for a configuration change may include at least one of: a preferred configuration for converting between analog signals and digital signals in the apparatus, or a preferred MCS level for the apparatus.

[0208] For example, the apparatus may send a configuration change request to the device based on the available battery power, etc. The configuration change request may include a preferred configuration to assist the device in determining a (new) operating configuration for converting between analog signals and digital signals in the device. In addition, if the preferred configuration is different from the current operating configuration (e.g., the operating configuration in which the device was running before the configuration change), the configuration change request may also include a preferred MCS level or index. For example, when the device requests a change from a configuration for high bit resolution to a configuration for low bit resolution, the configuration change request may include an MCS offset (e.g., if the MCS index under the configuration for high bit resolution ADC is N, the preferred MCS index under the configuration for low bit resolution may be N-offset).

[0209] The apparatus may send a request for a configuration change (eg, a configuration change request signal) via a dedicated scheduling request resource, a MAC-CE, a physical uplink control channel (PUCCH), or an RRC reconfiguration request.

[0210] In some embodiments, the configuration change may be performed differently than described above. The device may notify the device that the device is in a particular state (e.g., a low-power state). The device may perform a configuration change (e.g., switching to a configuration for low bit resolution due to low power in the device). When the device receives information that the device is in a particular state (e.g., a low-power state), the device may (implicitly) know that the device has performed a configuration change. The device may run according to a changed configuration (e.g., a configuration for low bit resolution) according to a predetermined protocol. For example, the device may run on a configuration for low bit resolution for a predetermined period of time. The predetermined period of time may be tracked by the device and the device using a timer. After a predetermined period of time, the device may switch back to the original configuration (e.g., a configuration for high bit resolution). When the timer times out, the device may implicitly know that the device has changed back to the original configuration.

[0211] In some embodiments, the apparatus may perform the configuration change after a configuration change delay. For example, if the device sends an indication to perform a configuration change at time T, the apparatus may perform the configuration change at time (T + configuration change delay). The configuration change delay may be determined based on one or more factors. By understanding the configuration change delay, the apparatus may know exactly when the apparatus begins using the new operating configuration.

[0212] In some embodiments, the configuration change delay may be determined based on the device's ability to convert between analog and digital signals. For example, a device with a strong ability to convert between analog and digital signals may have no delay (e.g., 0 ms), while a device with a weak ability to convert between analog and digital signals may have some delay (e.g., 2 ms).

[0213] In some embodiments, the configuration change delay may be determined based on the bit resolution associated with the previous configuration and / or the bit resolution associated with the operating configuration. For example, when the configuration changes from a 16-bit resolution configuration to an 8-bit resolution configuration, a certain configuration change delay may be applied, and when the configuration changes from a 16-bit resolution configuration to a 1-bit resolution configuration, a different configuration change delay may be applied. This is shown in Table 12 below. Each configuration change delay may be predetermined or reported by a device (e.g., within information related to the device's ability to convert between analog and digital signals).

[0215] Table 12 Example configuration change delays for different configuration changes

[0216] In some embodiments, the configuration change delay may be determined based on the spectrum range (carrier spectrum). Different configuration change delays may be configured for high and low frequencies.

[0217] In some embodiments, the configuration change delay may be determined based on a system parameter (numerology) of the active bandwidth part (BWP). Table 13 below shows an example.

[0219] Table 13 Example configuration change delays for different system parameters

[0220] In some embodiments, the configuration change delay may be determined according to the number of transmitting (Tx) antennas and / or the number of receiving (Rx) antennas. Table 14 below shows an example.

[0221] Number of Tx(Rx) antennas Configuration change delay (μs) 4 M1 8 M2

[0222] Table 14 Example configuration change delays for different numbers of antennas

[0223] In some embodiments, the configuration change delay may be determined according to the number of radio frequency (RF) chains. Table 15 below shows an example.

[0224] Number of RF chains Configuration change delay (μs) 2 M1 8 M2

[0225] Table 15 Example configuration change delays for different numbers of RF chains

[0236] In some embodiments, step 850a may be part of step 850 .

[0237] At step 860 , the device 312 may send, to the apparatus 302 , a modulation and coding scheme (MCS) value associated with a reference configuration for converting between analog signals and digital signals in the apparatus 302 .

[0238] A modulation and coding scheme (MCS) value associated with the reference configuration may be determined by the device 312 based on information related to the channel measurement to schedule transmissions with the apparatus 302.

That is, device 312 may send control information to apparatus 302, control information for scheduling transmissions, and control information including an MCS value to be used for transmissions, wherein the MCS value is associated with a reference configuration (e.g., the MCS value is selected from an MCS table corresponding to a configuration for converting between analog signals and digital signals in apparatus 302).

[0241] It should be noted that some or all of steps 810, 820, 850a, 860 and 870 are optional steps.

[0242] Fig. 9 FIG. 9 is a flow chart of an exemplary process 900 for adjusting a configuration for performing conversion between analog signals and digital signals in device 312 according to an embodiment of the present invention. Fig. 9 In the embodiment, the apparatus 302 may be a UE and the device 312 may be a TRP.

[0243] At step 910, the device 312 may determine a device operating configuration for converting between analog signals and digital signals in the device 312. The device operating configuration may be a device configuration for converting between analog signals and digital signals that the device 312 is to operate. The device operating configuration may be associated with at least one of a device bit resolution used by the device 312 when converting between analog signals and digital signals, a device sampling rate used by the device 312, or a device combination of a resolution and a sampling rate used by the device 312.

[0244] In some embodiments, the process of determining the device operation configuration may include selecting the device operation configuration from a plurality of device configurations for converting between analog signals and digital signals in the device. Each device configuration may be associated with at least one of: a corresponding device bit resolution used by the device 312 when converting between analog signals and digital signals, a corresponding device sampling rate used by the device 312, or a corresponding device combination of bit resolution and sampling rate used by the device 312. Multiple device configurations may be configured by the device 312.

[0245] At step 920, the device 312 may send information indicating the device operation configuration to the apparatus 302. The information indicating the device operation configuration may be sent via broadcast signaling, radio resource control (RRC), medium access control (MAC) control element (MAC-CE), or downlink control information (DCI).

[0246] In some embodiments, the information indicating the device operation configuration may include at least one of the following: an indication of a table of channel quality values ​​associated with the device operation configuration, or an indication of a table of modulation and coding scheme (MCS) values ​​associated with the device operation configuration. The table of channel quality values ​​may be a channel quality indicator (CQI) table associated with the device operation configuration. The CQI table may be one of a plurality of CQI tables, each of which may be associated with at least one device configuration for converting between analog signals and digital signals in the device 312. In some embodiments, some CQI tables may be derived from a master CQI table and may be a subset of the master CQI table, as described above and elsewhere in the present invention. The table of MCS values ​​may be an MCS table associated with the device operation configuration. The MCS table may be one of a plurality of MCS tables, each of which may be associated with at least one device configuration for converting between analog signals and digital signals in the device 312. In some embodiments, some MCS tables may be derived from a master MCS table and may be a subset of the master MCS table, as described above and elsewhere in the present invention.

[0247] At step 930, the device 312 may operate according to the information indicating the device operating configuration. In some embodiments, the operation process may include the device using a channel quality indicator (CQI) table and / or a modulation and coding scheme (MCS) table associated with the device operating configuration. The apparatus 302 also operates according to the device operating configuration, for example, using a CQI table and / or an MCS table associated with the device operating configuration, but is not shown.

[0248] Fig.10 FIG. 1 is a flow chart of an exemplary process 1000 for changing a configuration for performing conversion between analog signals and digital signals in the device 302 according to an embodiment of the present invention. Fig.10In the process 1000, one or more configurations and operation configurations are the same as those described above. Figure 8 The configuration described in process 800, etc. is similar.

[0249] At step 1010, the apparatus 302 may send a request for a configuration change to the device 312. In some embodiments, the request for a configuration change may include at least one of: a preferred configuration for converting between analog signals and digital signals in the apparatus, or a preferred MCS level for the apparatus. The request for a configuration change may be sent via a dedicated scheduling request resource, a MAC-CE, a physical uplink control channel (PUCCH), or an RRC reconfiguration request. Step 1010 is optional.

[0250] At step 1020, the device 312 may send information indicating a configuration change to the apparatus 302. In some embodiments, the information indicating the configuration change may include an explicit indication that the apparatus 302 performs the configuration change, and may be sent via broadcast signaling, a radio resource control (RRC), a medium access control (MAC) control element (MAC-CE), or downlink control information (DCI). In some embodiments, the information indicating the configuration change may be implicit, for example, may be or include information related to at least one of: a power consumption mode of the apparatus, a type of the apparatus, a scheduling MCS, a number of resource blocks, a transport block size, a number of transport blocks, a number of layers used for data transmission, or a carrier frequency range.

[0251] At step 1030 , the device 302 may perform a configuration change, including deactivating a previous configuration for converting between analog signals and digital signals in the device 302 , and activating an operating configuration according to the information indicating the configuration change.

[0252] In some embodiments, the device 302 may perform a configuration change after a configuration change delay. The configuration change delay may be determined based on at least one of the following: the device's ability to convert between analog and digital signals, a bit resolution associated with a previous configuration, a bit resolution associated with an operating configuration, a spectrum range, a system parameter of an active bandwidth part (BWP), a number of transmit (Tx) antennas, a number of receive (Rx) antennas, a number of radio frequency (RF) chains, or a carrier bandwidth or an active BWP bandwidth.

[0253] In some embodiments, the operational configuration may be for a device, a carrier or spectrum range, a BWP, an RF chain, a Tx antenna, a Tx antenna group, an Rx antenna, or an Rx antenna group.

[0254] The above embodiments are described in the context of UE communicating with TRP. However, in general, devices that wirelessly communicate with each other on time-frequency resources are not necessarily one or more UEs that communicate with the TRP. For example, two or more UEs can wirelessly communicate with each other via a sidelink using device-to-device (D2D) communication. As another example, two network devices (e.g., a ground base station and a non-ground base station (e.g., a drone)) can wirelessly communicate with each other via a backhaul link. The embodiments are not limited to uplink communications and / or downlink communications. For example, in the above embodiments, T-TRP 170 can be replaced with other devices, such as nodes or UEs in the network. Uplink communication / downlink communication can be sidelink communication. Therefore, as described above, device 302 can be a UE or a network device (e.g., a TRP), and device 312 can be a UE or a network device (e.g., a TRP).
