Description

METHOD AND APPARATUS FOR DETERMINING RESOURCE BASED ON RANDOM NUMBER IN A WIRELESS COMMUNICATION SYSTEM

[0001] The present disclosure relates to a technical field of wireless communication, and specifically, the present disclosure relates to a communication method, a user equipment (UE), and a base station.

[0002] 5G mobile communication technologies define broad frequency bands such that high transmission rates and new services are possible, and can be implemented not only in "Sub 6GHz" bands such as 3.5GHz, but also in "Above 6GHz" bands referred to as mmWave including 28GHz and 39GHz. In addition, it has been considered to implement 6G mobile communication technologies (referred to as Beyond 5G systems) in terahertz bands (for example, 95GHz to 3THz bands) in order to accomplish transmission rates fifty times faster than 5G mobile communication technologies and ultra-low latencies one-tenth of 5G mobile communication technologies.

[0003] At the beginning of the development of 5G mobile communication technologies, in order to support services and to satisfy performance requirements in connection with enhanced Mobile BroadBand (eMBB), Ultra Reliable Low Latency Communications (URLLC), and massive Machine-Type Communications (mMTC), there has been ongoing standardization regarding beamforming and massive MIMO for mitigating radio-wave path loss and increasing radio-wave transmission distances in mmWave, supporting numerologies (for example, operating multiple subcarrier spacings) for efficiently utilizing mmWave resources and dynamic operation of slot formats, initial access technologies for supporting multi-beam transmission and broadbands, definition and operation of BWP (BandWidth Part), new channel coding methods such as a LDPC (Low Density Parity Check) code for large amount of data transmission and a polar code for highly reliable transmission of control information, L2 pre-processing, and network slicing for providing a dedicated network specialized to a specific service.

[0004] Currently, there are ongoing discussions regarding improvement and performance enhancement of initial 5G mobile communication technologies in view of services to be supported by 5G mobile communication technologies, and there has been physical layer standardization regarding technologies such as V2X (Vehicle-to-everything) for aiding driving determination by autonomous vehicles based on information regarding positions and states of vehicles transmitted by the vehicles and for enhancing user convenience, NR-U (New Radio Unlicensed) aimed at system operations conforming to various regulation-related requirements in unlicensed bands, NR UE Power Saving, Non-Terrestrial Network (NTN) which is UE-satellite direct communication for providing coverage in an area in which communication with terrestrial networks is unavailable, and positioning.

[0005] Moreover, there has been ongoing standardization in air interface architecture / protocol regarding technologies such as Industrial Internet of Things (IIoT) for supporting new services through interworking and convergence with other industries, IAB (Integrated Access and Backhaul) for providing a node for network service area expansion by supporting a wireless backhaul link and an access link in an integrated manner, mobility enhancement including conditional handover and DAPS (Dual Active Protocol Stack) handover, and two-step random access for simplifying random access procedures (2-step RACH for NR). There also has been ongoing standardization in system architecture / service regarding a 5G baseline architecture (for example, service based architecture or service based interface) for combining Network Functions Virtualization (NFV) and Software-Defined Networking (SDN) technologies, and Mobile Edge Computing (MEC) for receiving services based on UE positions.

[0006] As 5G mobile communication systems are commercialized, connected devices that have been exponentially increasing will be connected to communication networks, and it is accordingly expected that enhanced functions and performances of 5G mobile communication systems and integrated operations of connected devices will be necessary. To this end, new research is scheduled in connection with eXtended Reality (XR) for efficiently supporting AR (Augmented Reality), VR (Virtual Reality), MR (Mixed Reality) and the like, 5G performance improvement and complexity reduction by utilizing Artificial Intelligence (AI) and Machine Learning (ML), AI service support, metaverse service support, and drone communication.

[0007] Furthermore, such development of 5G mobile communication systems will serve as a basis for developing not only new waveforms for providing coverage in terahertz bands of 6G mobile communication technologies, multi-antenna transmission technologies such as Full Dimensional MIMO (FD-MIMO), array antennas and large-scale antennas, metamaterial-based lenses and antennas for improving coverage of terahertz band signals, high-dimensional space multiplexing technology using OAM (Orbital Angular Momentum), and RIS (Reconfigurable Intelligent Surface), but also full-duplex technology for increasing frequency efficiency of 6G mobile communication technologies and improving system networks, AI-based communication technology for implementing system optimization by utilizing satellites and AI (Artificial Intelligence) from the design stage and internalizing end-to-end AI support functions, and next-generation distributed computing technology for implementing services at levels of complexity exceeding the limit of UE operation capability by utilizing ultra-high-performance communication and computing resources.

[0008] 5th generation (5G) or new radio (NR) mobile communications is recently gathering increased momentum with all the worldwide technical activities on the various candidate technologies from industry and academia. The candidate enablers for the 5G / NR mobile communications include massive antenna technologies, from legacy cellular frequency bands up to high frequencies, to provide beamforming gain and support increased capacity, new waveform (e.g., a new radio access technology (RAT)) to flexibly accommodate various services / applications with different requirements, new multiple access schemes to support massive connections, and so on.

[0009] In order to meet the increasing demand for wireless data communication services since the deployment of 4G communication systems, efforts have been made to develop improved 5G or pre-5G communication systems. Therefore, 5G or pre-5G communication systems are also called "Beyond 4G networks" or "Post-LTE systems".

[0010] In order to achieve a higher data rate, 5G communication systems are implemented in higher frequency (millimeter, mmWave) bands, e.g., 60 GHz bands. In order to reduce propagation loss of radio waves and increase a transmission distance, technologies such as beamforming, massive multiple-input multiple-output (MIMO), full-dimensional MIMO (FD-MIMO), array antenna, analog beamforming and large-scale antenna are discussed in 5G communication systems.

[0011] In addition, in 5G communication systems, developments of system network improvement are underway based on advanced small cell, cloud radio access network (RAN), ultra-dense network, device-to-device (D2D) communication, wireless backhaul, mobile network, cooperative communication, coordinated multi-points (CoMP), reception-end interference cancellation, etc.

[0012] In 5G systems, hybrid FSK and QAM modulation (FQAM) and sliding window superposition coding (SWSC) as advanced coding modulation (ACM), and filter bank multicarrier (FBMC), non-orthogonal multiple access (NOMA) and sparse code multiple access (SCMA) as advanced access technologies have been developed.

However, it should be understood that the reception path 250 can be implemented in a gNB and the transmission path 200 can be implemented in a UE. In some embodiments, the reception path 250 is configured to support codebook designs and structures for systems with 2D antenna arrays as described in embodiments of the present disclosure.

[0128] The transmission path 200 includes a channel coding and modulation block 205, a Serial-to-Parallel (S-to-P) block 210, a size N Inverse Fast Fourier Transform (IFFT) block 215, a Parallel-to-Serial (P-to-S) block 220, a cyclic prefix addition block 225, and an up-converter (UC) 230. The reception path 250 includes a down-converter (DC) 255, a cyclic prefix removal block 260, a Serial-to-Parallel (S-to-P) block 265, a size N Fast Fourier Transform (FFT) block 270, a Parallel-to-Serial (P-to-S) block 275, and a channel decoding and demodulation block 280.

[0129] In the transmission path 200, the channel coding and modulation block 205 receives a set of information bits, applies coding (such as Low Density Parity Check (LDPC) coding), and modulates the input bits (such as using Quadrature Phase Shift Keying (QPSK) or Quadrature Amplitude Modulation (QAM)) to generate a sequence of frequency-domain modulated symbols. The Serial-to-Parallel (S-to-P) block 210 converts (such as demultiplexes) serial modulated symbols into parallel data to generate N parallel symbol streams, where N is a size of the IFFT / FFT used in gNB 102 and UE 116. The size N IFFT block 215 performs IFFT operations on the N parallel symbol streams to generate a time-domain output signal. The Parallel-to-Serial block 220 converts (such as multiplexes) parallel time-domain output symbols from the Size N IFFT block 215 to generate a serial time-domain signal. The cyclic prefix addition block 225 inserts a cyclic prefix into the time-domain signal. The up-converter 230 modulates (such as up-converts) the output of the cyclic prefix addition block 225 to an RF frequency for transmission via a wireless channel. The signal can also be filtered at a baseband before switching to the RF frequency.

[0130] The RF signal transmitted from gNB 102 arrives at UE 116 after passing through the wireless channel, and operations in reverse to those at gNB 102 are performed at UE 116. The down-converter 255 down-converts the received signal to a baseband frequency, and the cyclic prefix removal block 260 removes the cyclic prefix to generate a serial time-domain baseband signal. The Serial-to-Parallel block 265 converts the time-domain baseband signal into a parallel time-domain signal. The Size N FFT block 270 performs an FFT algorithm to generate N parallel frequency-domain signals. The Parallel-to-Serial block 275 converts the parallel frequency-domain signal into a sequence of modulated data symbols. The channel decoding and demodulation block 280 demodulates and decodes the modulated symbols to recover the original input data stream.

[0131] Each of gNBs 101-103 may implement a transmission path 200 similar to that for transmitting to UEs 111-116 in the downlink, and may implement a reception path 250 similar to that for receiving from UEs 111-116 in the uplink. Similarly, each of UEs 111-116 may implement a transmission path 200 for transmitting to gNBs 101-103 in the uplink, and may implement a reception path 250 for receiving from gNBs 101-103 in the downlink.

[0132] Each of the components in FIGs. 2a and 2b can be implemented using only hardware, or using a combination of hardware and software / firmware. As a specific example, at least some of the components in FIGs. 2a and 2b may be implemented in software, while other components may be implemented in configurable hardware or a combination of software and configurable hardware. For example, the FFT block 270 and IFFT block 215 may be implemented as configurable software algorithms, in which the value of the size N may be modified according to the implementation.

[0133] Furthermore, although described as using FFT and IFFT, this is only illustrative and should not be interpreted as limiting the scope of the present disclosure. Other types of transforms can be used, such as Discrete Fourier transform (DFT) and Inverse Discrete Fourier Transform (IDFT) functions. It should be understood that for DFT and IDFT functions, the value of variable N may be any integer (such as 1, 2, 3, 4, etc.), while for FFT and IFFT functions, the value of variable N may be any integer which is a power of 2 (such as 1, 2, 4, 8, 16, etc.).

[0134] Although FIGs. 2a and 2b illustrate examples of wireless transmission and reception paths, various changes may be made to FIGs. 2a and 2b. For example, various components in FIGs. 2a and 2b can be combined, further subdivided or omitted, and additional components can be added according to specific requirements. Furthermore, FIGs. 2a and 2b are intended to illustrate examples of types of transmission and reception paths that can be used in a wireless network. Any other suitable architecture can be used to support wireless communication in a wireless network.

The embodiment of UE 116 shown in FIG. 3a is for illustration only, and UEs 111-115 of FIG. 1 can have the same or similar configuration. However, a UE has various configurations, and FIG. 3a does not limit the scope of the present disclosure to any specific implementation of the UE.

[0136] UE 116 includes an antenna 301, a radio frequency (RF) transceiver 302, a transmission (TX) processing circuit 303, a microphone 304, and a reception (RX) processing circuit 305.

[0137] The RF transceiver 302 receives an incoming RF signal transmitted by a gNB of the wireless network 100 from the antenna 301. The RF transceiver 302 down-converts the incoming RF signal to generate an intermediate frequency (IF) or baseband signal. The IF or baseband signal is transmitted to the RX processing circuit 305, where the RX processing circuit 305 generates a processed baseband signal by filtering, decoding and / or digitizing the baseband or IF signal. The RX processing circuit 305 transmits the processed baseband signal to speaker 306 (such as for voice data) or to controller / processor 307 for further processing (such as for web browsing data).

[0138] The TX processing circuit 303 receives analog or digital voice data from microphone 304 or other outgoing baseband data (such as network data, email or interactive video game data) from controller / processor 307. The TX processing circuit 303 encodes, multiplexes, and / or digitizes the outgoing baseband data to generate a processed baseband or IF signal. The RF transceiver 302 receives the outgoing processed baseband or IF signal from the TX processing circuit 303 and up-converts the baseband or IF signal into an RF signal transmitted via the antenna 301.

[0139] The controller / processor 307 can include one or more processors or other processing devices and execute an OS 312 stored in the memory 311 in order to control the overall operation of UE 116. For example, the controller / processor 307 can control the reception of forward channel signals and the transmission of backward channel signals through the RF transceiver 302, the RX processing circuit 305 and the TX processing circuit 303 according to well-known principles. In some embodiments, the controller / processor 307 includes at least one microprocessor or microcontroller.

[0140] The controller / processor 307 is also capable of executing other processes and programs residing in the memory 311, such as operations for channel quality measurement and reporting for systems with 2D antenna arrays as described in embodiments of the present disclosure.

In some embodiments, the controller / processor 307 is configured to execute the application 313 based on the OS 312 or in response to signals received from the gNB or the operator. The controller / processor 307 is also coupled to an I / O interface 308, where the I / O interface 308 provides UE 116 with the ability to connect to other devices such as laptop computers and handheld computers. I / O interface 308 is a communication path between these accessories and the controller / processor 307.

[0141] The controller / processor 307 is also coupled to the input device(s) 309 and the display 310. An operator of UE 116 can input data into UE 116 using the input device(s) 309. The display 310 may be a liquid crystal display or other display capable of presenting text and / or at least limited graphics (such as from a website). The memory 311 is coupled to the controller / processor 307. A part of the memory 311 can include a random access memory (RAM), while another part of the memory 311 can include a flash memory or other read-only memory (ROM).

[0142] Although FIG. 3a illustrates an example of UE 116, various changes can be made to FIG. 3a. For example, various components in FIG. 3a can be combined, further subdivided or omitted, and additional components can be added according to specific requirements. As a specific example, the controller / processor 307 can be divided into a plurality of processors, such as one or more central processing units (CPUs) and one or more graphics processing units (GPUs). Furthermore, although FIG. 3a illustrates that the UE 116 is configured as a mobile phone or a smart phone, UEs can be configured to operate as other types of mobile or fixed devices.

[0143] FIG. 3b illustrates an example gNB 102 according to the present disclosure. The embodiment of gNB 102 shown in FIG. 3b is for illustration only, and other gNBs of FIG. 1 can have the same or similar configuration. However, a gNB has various configurations, and FIG. 3b does not limit the scope of the present disclosure to any specific implementation of a gNB. It should be noted that gNB 101 and gNB 103 can include the same or similar structures as gNB 102.

[0144] As shown in FIG. 3b, gNB 102 includes a plurality of antennas 370a-370n, a plurality of RF transceivers 372a-372n, a transmission (TX) processing circuit 374, and a reception (RX) processing circuit 376. In certain embodiments, one or more of the plurality of antennas 370a-370n include a 2D antenna array. gNB 102 also includes a controller / processor 378, a memory 380, and a backhaul or network interface 382.

[0145] RF transceivers 372a-372n receive an incoming RF signal from antennas 370a-370n, such as a signal transmitted by UEs or other gNBs. RF transceivers 372a-372n down-convert the incoming RF signal to generate an IF or baseband signal. The IF or baseband signal is transmitted to the RX processing circuit 376, where the RX processing circuit 376 generates a processed baseband signal by filtering, decoding and / or digitizing the baseband or IF signal. RX processing circuit 376 transmits the processed baseband signal to controller / processor 378 for further processing.

[0146] The TX processing circuit 374 receives analog or digital data (such as voice data, network data, email or interactive video game data) from the controller / processor 378. TX processing circuit 374 encodes, multiplexes and / or digitizes outgoing baseband data to generate a processed baseband or IF signal. RF transceivers 372a-372n receive the outgoing processed baseband or IF signal from TX processing circuit 374 and up-convert the baseband or IF signal into an RF signal transmitted via antennas 370a-370n.

[0147] The controller / processor 378 can include one or more processors or other processing devices that control the overall operation of gNB 102. For example, the controller / processor 378 can control the reception of forward channel signals and the transmission of backward channel signals through the RF transceivers 372a-372n, the RX processing circuit 376 and the TX processing circuit 374 according to well-known principles. The controller / processor 378 can also support additional functions, such as higher-level wireless communication functions. For example, the controller / processor 378 can perform a Blind Interference Sensing (BIS) process such as that performed through a BIS algorithm, and decode a received signal from which an interference signal is subtracted. A controller / processor 378 may support any of a variety of other functions in gNB 102. In some embodiments, the controller / processor 378 includes at least one microprocessor or microcontroller.

[0148] The controller / processor 378 is also capable of executing programs and other processes residing in the memory 380, such as a basic OS. The controller / processor 378 can also support channel quality measurement and reporting for systems with 2D antenna arrays as described in embodiments of the present disclosure. In some embodiments, the controller / processor 378 supports communication between entities such as web RTCs. The controller / processor 378 can move data into or out of the memory 380 as required by an execution process.

[0149] The controller / processor 378 is also coupled to the backhaul or network interface 382. The backhaul or network interface 382 allows gNB 102 to communicate with other devices or systems through a backhaul connection or through a network. The backhaul or network interface 382 can support communication over any suitable wired or wireless connection(s). For example, when gNB 102 is implemented as a part of a cellular communication system, such as a cellular communication system supporting 5G or new radio access technology or NR, LTE or LTE-A, the backhaul or network interface 382 can allow gNB 102 to communicate with other gNBs through wired or wireless backhaul connections. When gNB 102 is implemented as an access point, the backhaul or network interface 382 can allow gNB 102 to communicate with a larger network, such as the Internet, through a wired or wireless local area network or through a wired or wireless connection. The backhaul or network interface 382 includes any suitable structure that supports communication through a wired or wireless connection, such as an Ethernet or an RF transceiver.

[0150] The memory 380 is coupled to the controller / processor 378. A part of the memory 380 can include an RAM, while another part of the memory 380 can include a flash memory or other ROMs. In certain embodiments, a plurality of instructions, such as the BIS algorithm, are stored in the memory. The plurality of instructions are configured to cause the controller / processor 378 to execute the BIS process and decode the received signal after subtracting at least one interference signal determined by the BIS algorithm.

[0151] As will be described in more detail below, the transmission and reception paths of gNB 102 (implemented using RF transceivers 372a-372n, TX processing circuit 374 and / or RX processing circuit 376) support aggregated communication with FDD cells and TDD cells.

[0152] Although FIG. 3b illustrates an example of gNB 102, various changes may be made to FIG. 3b. For example, gNB 102 can include any number of each component shown in FIG. 3a. As a specific example, the access point can include many backhaul or network interfaces 382, and the controller / processor 378 can support routing functions to route data between different network addresses. As another specific example, although shown as including a single instance of the TX processing circuit 374 and a single instance of the RX processing circuit 376, gNB 102 can include multiple instances of each (such as one for each RF transceiver).

[0153] A time domain unit (also called time unit) in the embodiment of the present disclosure may be: an Orthogonal Frequency Division Multiplexing (OFDM) symbol, an OFDM symbol group (consisting of a plurality of OFDM symbols), a Slot, a Slot group (consisting of a plurality of Slots), a Subframe, a Subframe group (consisting of a plurality of Subframes), a System Frame, and a System Frame group (consisting of a plurality of System Frames). It can also be an absolute time unit, such as 1 millisecond, 1 second, etc. The time unit can also be a combination of various granularities, such as N1 time slots plus N2 OFDM symbols, etc. It can also be a time length of an On-Off Keying (OOK) chip.

[0154] A frequency domain unit (also called frequency unit) in the embodiment of the present disclosure may be: a subcarrier, a subcarrier group (consisting of a plurality of subcarriers), a resource block (RB), which can also be called physical resource block (PRB), a resource block group (consisting of a plurality of RBs), a bandwidth part (BWP), a bandwidth part group (consisting of a plurality of BWPs), a band / carrier, and a band group / carrier group. It can also be an absolute frequency domain unit, such as 1 Hz, 1 kHz, etc. The frequency domain unit can also be a combination of a plurality of granularities, such as M1 PRBs plus M2 subcarriers, etc.

[0155] The transmission links of a wireless communication system mainly include: a downlink communication link from 5G New Radio (NR) gNB to User Equipment (UE), an uplink communication link from UE to the network, and a SideLink (SL) from UE to UE, which can also be referred to as a bypass communication link.

[0156] In some special scenarios such as Internet of Things scenarios, in order to further reduce the energy loss at the terminal side and at the same time to reduce the deployment cost of the devices, an ambient power enabled Internet of Things (A-IoT) device or a radio frequency signal power enabled Internet of Things device have been proposed to achieve a wireless communication with lower hardware complexity and lower power consumption. The A-IoT devices acquires indication information by receiving downlink signals or sidelink communication links, such as R2D (Reader to Device, where the reader is a base station or other device) signals. The A-IoT device receives the peripheral RF signals (Radio Frequency Signal, a radio signal), modulates the data onto the RF signals, and establish a wireless communication link with the base station and / or the UE by means of backward scattering, e.g., D2R (Device to Reader) signals, or the A-IoT devices with power storage can actively transmit uplink signals. Or, the A-IoT device converts the received energy into the AC or DC voltage by receiving the periphery RF signals and / or collecting energy from energy sources such as solar, vibration, thermal, wind, etc. For example, RF signals are converted to DC signals by RF-DC (Direct Current) converters, and then these powers are transmitted to an electrical energy storage device such as a rechargeable battery or capacitor for establishing a wireless communication link. At this point, it is necessary to enhance the existing communication mechanisms or processes of the communication system, such as the random access process, the inventory process, and the command process of the A-IoT devices.

[0157] The exemplary embodiments of the present disclosure are further described below in conjunction with the accompanying drawings.

[0158] The text and drawings are provided as examples only to help readers understand the present disclosure. They are not intended and should not be interpreted as limiting the scope of the present disclosure in any way. Although certain embodiments and examples have been provided, based on the content disclosed herein, it is obvious to those skilled in the art that modifications to the illustrated embodiments and examples can be made without departing from the scope of the present disclosure.

[0159] An embodiment of the present disclosure provides a method performed by a UE in a communication system. As shown in FIG. 4, the method includes the following steps.

[0160] Step S101, receiving first configuration information, and the first configuration information includes first information related to frequency domain resources, and second information related to a first random number.

[0161] Wherein, the first information related to the frequency domain resources comprises at least one of a number K of frequency domain resources, a start point of the frequency domain resources, a bandwidth, and an interval between (adjacent) frequency domain resources.

[0162] The second information related to the first random number is used to limit the generation of a first random number range, such as a maximum value, for determining a first threshold value for a neighboring UE.

[0163] Step S102, generating a first random number based on the second information.

[0164] As an example, the second information related to the first random number may be represented as a Q-value, and the UE may generate a random number from 0 to -1 based on the Q-value, but is not limited to thereto.

[0165] Step S103, determining, based on the first random number, a first frequency domain resource among the frequency domain resources, and transmitting a first uplink signal on the first frequency domain resource.

[0166] In the embodiment of the present disclosure, the UE may determine K frequency domain resources in the frequency domain depending on the first information, and the UE determines the position of the first frequency domain resource on which the UE transmits the first uplink signal depending on the generated first random number, and an association relationship between the first random number and the frequency domain resources, and thereby transmits the first uplink signal, which may be, for example, the first uplink signal for random access, etc., but is not limited to this, on the first frequency domain resource.

[0167] In the embodiment of the present disclosure, the UE may include an A-IoT device, but is not limited thereto.

[0168] According to the method performed by the UE according to the embodiment of the present disclosure, the UE can select a suitable first frequency domain resource based on the configured second information to transmit the first uplink signal, thereby improving the transmission efficiency of the first uplink signal.

[0169] In the embodiment of the present disclosure, if the start point of the frequency domain resource is not configured by the first configuration information, such as the start point of the frequency domain resource is not included in the first information, the start point of the frequency domain resource may be fixed to the frequency point of the unmodulated first carrier, wherein the first carrier may be an incident carrier, but is not limited to this.

[0170] In the embodiment of the present disclosure, if the bandwidth and / or the interval between the frequency domain resources is not configured by the first configuration information, the bandwidth and / or the interval between the frequency domain resources may be predefined values.

[0171] In the embodiment of the present disclosure, in the case of receiving the first signaling, the first random number is reduced by a predetermined value, and when the first random number is reduced to 0~K-1, the first frequency domain resource is a frequency domain resource associated with the first random number, wherein K denotes the number of frequency domain resources.

[0172] In an alternative implementation, if the UE supports frequency modulation, the generated first random number is an element of set, the first random number is reduced by K in the case of receiving the first signaling. When the first random number is reduced to 1~K-1, the first frequency domain resource is a frequency domain resource associated with the first random number, and the UE transmits the first uplink signal on the frequency domain resource associated with the first random number, otherwise, the UE does not send the first uplink signal. If the UE does not support frequency modulation, the generated first random number is an element of the *K set, the first random number is reduced by K in the case of receiving the first signaling. When the first random number is reduced to 0, the first frequency domain resource is the frequency domain resource corresponding to the frequency point of the first carrier, and the UE transmits the first uplink signal on the first frequency domain resource, otherwise, the UE does not transmit the first uplink signal. Wherein, sup denotes the taking of the upper bound and Q denotes the second information related to the first random number.

[0173] In another optional implementation, if the UE supports frequency modulation, the generated first random number is an element of set, the first random number is reduced by K in the case of receiving the first signaling. When the first random number is reduced to 1~K-1, the first frequency domain resource is the frequency domain resource associated with the first random number, and the UE transmits the first uplink signal on the frequency domain resource associated with the first random number, otherwise, the UE does not transmit the first uplink signal. If the UE does not support frequency modulation, the generated first random number is an element of set, the first random number is reduced by 1 in the case of receiving the first signaling. When the first random number is reduced to 0, the first frequency domain resource is the frequency domain resource corresponding to the frequency point of the first carrier, and the UE transmits the first uplink signal on the first frequency domain resource, otherwise, the UE does not transmit the first uplink signal. Wherein, sup denotes the taking of the upper bound and Q denotes the second information related to the first random number.

[0174] In yet another optional implementation, the UE receives the first downlink signal and acquires indication information of the first downlink signal, wherein the indication information may comprise at least one of the following: a Q value, a number K of frequency domain resources, a start point of the frequency domain resources, a bandwidth, an interval between adjacent frequency domain resources. The first random number generated by the UE according to the indicated Q value is an element of set, and the first random number is reduced by K in the case of receiving the first signaling. When the first random number is reduced to 0~K-1, the first frequency domain resource is a frequency domain resource associated with the first random number, and the UE transmits the first uplink signal on the first frequency domain resource associated with the first random number, otherwise, the UE does not transmit the first uplink signal. Wherein, Q denotes the second information associated with the first random number.

[0175] For the embodiment of the present disclosure, the above first signaling may be signaling for indicating a frame header of an indefinite length frame and / or indicating to let the first random number subtract a predetermined value, such as queryRep (query repeat) signaling, but it is not limited thereto.

[0176] As an example, as shown in FIG. 5, assuming that Q=4 and K=3, set includes values of 0~15, the first random number is reduced by K for each queryRep received, and the first random number can be reduced to 0~2, wherein the first random number 1~2 can be used in case the UE supports frequency modulation, and the first random number 0 can be used in case the UE does not support frequency modulation.

[0177] Or, the set includes {1, 2, 4, 5, 7, 8, 10, 11, 13, 14}, and the first random number is subtracted by K for each queryRep received. The first random number can be reduced to 1~2, which can be used in case the UE supports frequency modulation.

[0178] Or, the *K set includes {0, 3, 6, 9, 12, 15}, and the first random number is reduced by K for each queryRep received. The first random number can be reduced to 0, which can be used in case the UE does not support frequency modulation.

[0179] Or, the set includes values 0~5, and the first random number is subtracted by 1 for each queryRep received. The first random number can be reduced to 0, which can be used in case the UE does not support frequency modulation.

[0180] That is, either of the last two rows of random numbers in FIG. 5 can be selected to be used for the case where the UE does not support frequency modulation. Optionally, a UE that does not support frequency modulation may transmit the D2R in Time-Division Multiplexing (TDM) using the frequency point where the incident carrier is located.

[0181] In the embodiment of the present disclosure, the method for determining a frequency domain resource position by the UE can be as follows: the UE determines a start point of a first frequency domain resource from low to high in the frequency domain based on a start point of the frequency domain resource in the first configuration information, determines a first frequency domain resource based on a start point of the first frequency domain resource and the bandwidth, determines a start point of the second frequency domain resource based on the end position of the first frequency domain resource and the interval between adjacent frequency domain resources, determines the second frequency domain resource based on the start point of the second frequency domain resource and the bandwidth, and so on.

[0182] It should be understood by those skilled in the art that the above method for determining the frequency domain resources position is only a schematic description and does not constitute a limitation to the embodiment of the present disclosure. Appropriate changes based on the example can also be applied to the present disclosure, so it should also be included in the protection scope of the present disclosure.

[0183] In the embodiment of the present disclosure, the frequency domain resource associated with the first random number may be determined by the association relationship between the first random number and the frequency domain resource. Optionally, based on a frequency or an index of the frequency domain resource, the first random number of 0~K-1 is associated with the frequency domain resource. For example, the association relationship may be a one-to-one mapping of random numbers from 1 to K-1 to frequency domain resource frequencies in order from low to high. For another example, the association relationship may be a one-to-one mapping of random numbers from 1 to K-1 to frequency resource indexes in order from small to large. Wherein, the frequency domain resources herein do not include the frequency domain resources corresponding to the frequency points before frequency modulation.

[0184] In the embodiment of the present disclosure, in the case where the first uplink signal is transmitted by frequency division multiplexing, the first acknowledgement signals corresponding to L (where L is an integer less than or equal to K) first uplink signal contains at least one of the following information.

[0185] (1) K consecutive information bit groups, the K information bit groups are associated with K frequency domain resources respectively, and the bit length of each information bit group is the bit length of the first uplink signal.

[0186] Wherein, the first acknowledgement signal may be a fixed length signal, e.g., the length of the first acknowledgement signal is equal to K* bit length of the first uplink signal. The information bit group of the bit length of each first uplink signal of the first acknowledgement signal from MSB to LSB corresponds to the frequency domain resource with the frequency from LSB to MSB or the frequency resource index from small to large. According to the association relationship between the frequency domain resource and the first random number, and / or determining the random number corresponding to the information bit group of the first acknowledgement signal, the UE determines the information bit group in the associated first acknowledgement signal.

[0187] (2) L information bits with a first bit length, each first bit length includes a bit length of and a bit length of the first uplink signal, and each information bit of bit length of includes a value of a first random number of 0~K-1.

[0188] Wherein, the first acknowledgement signal may be a signal with a variable length, for example, the length of the first acknowledgement signal is less than or equal to K* first bit length, and the first bit length is equal to bits and the bit length of the first uplink signal transmitted by the UE. The information bits of the first bit length from MSB to LSB correspond to bits and bits of the first uplink signal transmitted by the UE.

[0189] Optionally, the value of the bit indicates the value of the first random number whose range is 0~K-1. When the UE receives the first acknowledgement signal, if the UE determines that the generated random number and the value of the first bits in a first bit length in the received first acknowledgement signal are the same, the UE determines that the information bit indicated by the first acknowledgement signal is the information bit after the first bit of the first bit length, and the length of the information bit is the bit length of the first uplink signal. Optionally, if the information bit is the same as the information bit of the first uplink signal transmitted by the UE, the UE transmits a second uplink signal for random access and / or transmitting an identifier of the UE (which can also be called an identifier, a marker or an identification mark, etc.).

[0190] Therefore, the first acknowledgement signal can indicate information bits less than or equal to K first uplink signals.

[0191] In the embodiment of the present disclosure, the related information of the on state (which may also be other names, such as activation state) and / or the off state (which may also be other terms, such as deactivation state) and / or the sleep state (which may also be other terms, such as hibernation state) of the UE and the conditions for transition between states are provided.

[0192] In the embodiment of the present disclosure, the UE in the off state may receive a carrier for providing energy and / or a first downlink signal for wake-up or inventory, and the first downlink signal may include the first configuration information described above, i.e., the first configuration information may be received while the UE is in the off state.

[0193] In the embodiment of the present disclosure, the first downlink signal (e.g. the first configuration information) may further comprise: a first identifier for identifying the at least one UE. Optionally, the first identifier includes at least one of the following.

[0194] (1) a UE Identity document (ID) or a UE index.

[0195] For example, it can be International Mobile Subscriber Identity (IMSI); If the IMSI of the UE is the same as the received identifier, the UE may initiate a random access process or an inventory process or respond to the first downlink signal.

[0196] (2) The first-predetermined bit number of the UE ID or the UE index.

[0197] Such as the first X bits of the UE-specific ID or index, wherein X is a predefined real number and X>0. For example, it may be the first X bits of the IMSI. If the first X bits of the IMSI of the UE are the same as the received identifier, the UE may initiate a random access process or an inventory process or respond to the first downlink signal.

[0198] (3) A predetermined sequence, which is used for determining all UEs or neighboring UEs that have received the predetermined sequence, wherein the neighboring UEs are UEs whose received signal strength of the first configuration information is greater than a first threshold value, and the first threshold value is predefined or preconfigured by the first configuration information.

[0199] For example, it may be a predefined sequence or information bit, e.g., the information bits corresponding to the domain where the identifier is located are all 0 or all 1, but are not limited to this, and may be other sequences. Such special sequence is used to wake up or inventory all UEs or neighboring UEs that have received the predetermined sequence. For example, when the UE receives the special sequence, the UE may initiate a random access process or an inventory process or respond to the first downlink signal. Wherein, the neighboring UE may also be a UE whose received signal strength of the first downlink signal is greater than a first threshold value, and the first threshold value may be predefined or preconfigured by the first downlink signal.

[0200] (4) A first multiple of the second random number.

[0201] For example, it may be S1* second random number, wherein S1 may be a predefined real number, or S1 can be subject to base station implementation, S1 is an integer greater than or equal to 1, the second random number may be a random number transmitted in the first uplink signal, and the length of the second random number is predefined, for example, 16bit. The UE acquires the information bits of the UE identifier indicated by the first configuration information in the corresponding domain, and depending on the length of the second random number from MSB to LSB, information bits per second random number length is a second random number, and so on, the UE may acquire S1 second random numbers indicated by the first configuration information to indicate S1 UEs.

[0202] (5) A second multiple of UE ID or UE index.

[0203] For example, it may be S2*UE ID or S2*UE index to indicate S2 UEs. The UE acquires the information bits of the UE identifier indicated by the first configuration information in the corresponding domain, and depending on the length of the UE ID or UE index from MSB to LSB, information bits per UE ID or UE index length is one UE ID or UE index, and so on, S2 UE IDs or UE indexes indicated by the first configuration information can be obtained.

[0204] In the embodiment of the present disclosure, the first downlink signal (such as the first configuration information) may further comprise: a flag indicating whether the UE is inventoried. The flag may be 1-bit indication information, which may be indicated by the first downlink signal or determined implicitly. For example, if the identifier of the UE is the same as the identifier indicated by the first downlink signal, the flag indicating whether the UE is inventoried is set to "0", and if the identifier of the UE is different from the identifier indicated by the first downlink signal, the flag indicating whether the UE is inventoried is set to "1". It should be noted that "0" and "1" are used here for illustrative purposes only, and their values are not limited.

[0205] In the embodiment of the present disclosure, in the case where the first downlink signal (such as the first configuration information) is used to wake up the UE, if the first identifier is different from the identifier of the UE, the UE remains in the off state; if the first identifier is the same as the identifier of the UE, or if the first identifier is the same as the identifier of the UE and the generated first random number is equal to 0, the UE enters an on state; and if the first identifier is the same as the identifier of the UE and the generated first random number is not equal to 0, or the first random number generated by the UE in the on state is not equal to 0, the UE enters a sleep state.

[0206] In one example, the UE in the off state receives the first downlink signal, and if the identifier of the UE is different from the first identifier indicated by the first downlink signal, the UE remains in the off state. If the identifier of the UE is the same as the first identifier indicated by the first downlink signal, the UE should transition from the off state to the on state. If the first random number generated by the UE is equal to 0, the UE remains in the on state, and if the first random number generated by the UE is not 0, the UE transitions from the on state to the sleep state. This operation considers the first downlink signal as a signal for waking up the UE. In order to reduce the power consumption of the UE in the off state, a feasible way is to limit the number of information bits of the first downlink signal, e.g. the first downlink signal only indicates an identifier for identifying one or more UEs. Optionally, the UE acquires the second information for limiting the generation of the first random number range through a signal for indicating the downlink signal transmission configuration. The downlink signal transmission configuration may be at least one of the following: data rate, the presence or absence of the pilot, and a value M of the number of OOK chips transmitted in one OFDM symbol, e.g., M=2 or M=4.

[0207] In another example, the UE in the off state receives the first downlink signal, and if the identifier of the UE is different from the first identifier indicated by the first downlink signal, the UE remains in the off state. If the identifier of the UE is the same as the first identifier indicated by the first downlink signal and the generated first random number is 0, the UE transitions from the off state to the on state, and transmits the first uplink signal; if the identifier of the UE is the same as the first identifier indicated by the first downlink signal and the first random number is not 0, the UE transitions from the off state to the sleep state. This operation avoids the power loss caused by the wake-up of the uplink RF link of the UE that cannot acquires the uplink resources, and is more suitable for the case that the first downlink signal indicates the second information for limiting the generation of the first random number range.

[0208] For the embodiment of the present disclosure, the identifier of the UE being the same as the first identifier indicated by the first downlink signal may be that the information bit length of the identifier of the UE is the same as that of the first identifier indicated by the first downlink signal, and the information bit value of the identifier of the UE is the same as that of the first identifier indicated by the first downlink signal; or the first X bits of the identifier of the UE is the same as the first X bits of the first identifier indicated by the first downlink signal; or the UE receives a predetermined sequence or predetermined information bits (for waking up or inventorying all UEs or neighboring UEs that have received the predetermined sequence or the predetermined information bit). The identifier of the UE being different from the first identifier indicated by the first downlink signal may be that the information bit length of the identifier of the UE is different from that of the identifier indicated by the first downlink signal, and / or the information bit value of the identifier of the UE is different from that of the identifier indicated by the first downlink signal; or the first X bits of the identifier of the UE is different from the first X bits of the first identifier indicated by the first downlink signal; or the UE receives not a predetermined sequence or predetermined information bits (for waking up or inventorying all UEs or neighboring UEs that have received the predetermined sequence or the predetermined information bit).

[0209] In the embodiment of the present disclosure, as shown in FIG. 6, the UE may receive downlink signals or R2D signals, and may transmit uplink signals or D2R signals.

[0210] Optionally, if the UE stays in the on state, the UE may receive at least one of the following downlink signals or R2D signals.

[0211] (1) A first acknowledgement signal, which is used to confirm that a first uplink signal is received in a random access process.

[0212] Optionally, the first acknowledgement signal may comprise information bits of the first uplink signal.

[0213] (2) A first command, which is used to indicate the UE to at least one of transmit uplink data, perform reading, perform writing, perform locking, enter an arbitrary state, or no longer respond to the downlink signals.

[0214] Optionally, the first command may comprise an identifier indicating one or more UEs.

[0215] (3) A first signaling, which is used to indicate a frame header of an indefinite length frame and / or indicating to let the first random number subtract a predetermined value;

[0216] In the embodiment of the present disclosure, the first signaling may be exemplarily introduced by using the queryRep signal, wherein the first signaling may include, but is not limited to, the queryRep signal. Wherein, K is a preconfigured or predefined value, and K is an integer greater than or equal to 1.

[0217] (4) A second signaling, which is used to regenerate a first random number.

[0218] Optionally, the second signaling comprises information to adjust the Q value that limits the generation of the random number range, e.g., Q unchanged, Q+1 or Q-1, etc. In the embodiment of the present disclosure, the second signaling may be exemplarily introduced by using the queryAdjust, wherein the second signaling may include, but is not limited to, the queryAdjust signal.

[0219] (5) A second command, which is used to indicate at least one UE to transmit uplink data.

[0220] Optionally, the first command may comprise an identifier indicating one or more UEs.

[0221] Optionally, if the UE stays in the on state, the UE may also transmit at least one of the following uplink signals.

[0222] (1) A first uplink signal.

[0223] Optionally, the above first uplink signal is transmitted during on state of the UE.

[0224] Optionally, the first uplink signal may be used for random access.

[0225] (2) A second uplink signal.

[0226] The second uplink signal is used for random access and / or transmitting the identifier of the UE.

[0227] (3) A second acknowledgement signal in response to the first command.

[0228] Optionally, the second acknowledgement signal comprises all or part of the identifier of the UE or one first random number generated depending on the second information.

[0229] (4) Uplink data, which may also be referred to as an uplink data signal, the uplink data is in response to the second command.

[0230] In the embodiment of the present disclosure, for at least two uplink signals of the first uplink signal, the second uplink signal, the second acknowledgement signal, and the uplink data, at least one of the following frequency domain resource configurations of the uplink signals is the same: a frequency domain start position, a frequency domain end position, and a bandwidth.

[0231] For example, the frequency domain start position for the UE transmitting the second uplink signal is the same as that of transmitting the first uplink signal, and / or the frequency domain end position for the UE transmitting the second uplink signal is the same as that of transmitting the first uplink signal, and / or the bandwidth for the UE transmitting the second uplink signal is the same as that of transmitting the first uplink signal, and the unit of bandwidth may be kHz or MHz. This method no longer needs to indicate the frequency domain resources of the second uplink signal, which can save the signaling overhead and the power consumption of UE decoding.

[0232] For another example, when the frequency domain resources are not indicated, the UE determines that the frequency domain resources for the UE transmitting the second acknowledgement signal and / or the uplink data are the same. In this way, the second command no longer needs to indicate frequency domain resources for transmitting uplink data.

[0233] For another example, when the frequency domain resources are not indicated, the frequency domain resources for the UE transmitting the second acknowledgement signal and / or the uplink data and / or the first uplink signal and / or the second uplink signal are the same. In this way, when the UE determines the frequency domain resource for transmitting the first uplink signal, the UE will not change the frequency domain position for transmitting the uplink signal during the current inventory process, which may reduce the overhead of the signaling additional indicating the frequency domain resource position.

[0234] In the embodiment of the present disclosure, the UE in the on state may enter the sleep state under at least one of the following situations:

[0235] (1) the UE enters a sleep state after the first time interval, in the case that during the first time interval after the end position of transmitting the first uplink signal, the first acknowledgement signal is not received, or the first acknowledgement signal is received but the first acknowledgement signal does not include the information bits of the first uplink signal, and;

[0236] (2) enters the sleep state, in the case that the first command or the second command is not received until a position meeting a second time interval after the end position of transmitting the second uplink signal;

[0237] (3) enters the sleep state, in the case that the first command or the second command is not received until a position meeting a second time interval after the end position of transmitting the uplink data;

[0238] Optionally, if the UE is in a sleep state, the UE may receive the first signaling and / or the second signaling, and does not expect to transmit uplink signals.

[0239] Optionally, the UE transitions to the sleep state, and the UE in the sleep state may regenerate the first random number based on the second signaling. In the case of receiving the first signaling, the first random number is reduced by a predetermined value, and when the first random number is reduced to 0~K-1, it enters the on state.

[0240] As an example, the UE acquires a new Q value by receiving queryAdjust, and regenerates the first random number. The UE in the sleep state receives a QueryRep, and the random number of the UE is reduced by K. When the random number of the UE is greater than or equal to 0 and less than or equal to K-1, the UE transitions from the sleep state to the on state and transmits the first uplink signal.

[0241] In the embodiment of the present disclosure, the UE may also start a timer when entering the sleep state, and expect to receive the first command and / or the second command during the timer operates, and the UE does not expect to receive the first signaling and / or the second signaling.

[0242] Optionally, the started timer is a timer for indicating the tag state inversion, and the timer length may be predefined. Optionally, the timer length is in milliseconds or seconds.

[0243] Optionally, when the first command is received and the identifier indicated by the first command is the same as that of the UE, or when the second command is received and the identifier indicated by the second command is the same as that of the UE, stopping the timer and entering the on state.

[0244] Optionally, when the first command is not received, or the first command is received but the identifier indicated by the first command is different from that of the UE, or when the second command is not received, or the second command is received but the identifier indicated by the second command is different from that of the UE, remaining in the sleep state and the keeping operation of the timer. Optionally, the timer does not restart or update.

[0245] Optionally, when the timer expires, the UE enters the off state, and / or the flag of whether the UE is inventoried is inverted, or the flag of whether the UE is inventoried is set to the already inventoried state.

[0246] Optionally, when the UE enters the sleep state, the timer is started under at least one of the following situations:

[0247] (1) The second command is not received in a third time interval after transmitting the second acknowledgement signal.

[0248] For example, if the UE in the on state does not receive the second command at the third time interval after transmitting the second acknowledgement signal, the UE in the on state starts from the end position of transporting or transmitting the second acknowledgement signal and a preconfigured or predefined maximum waiting time (such as the third time interval), the UE transitions to the sleep state and starts a timer for indicating the tag state inversion. If the UE receives the second command during the timer operates, and the identifier indicated by the second command is the same as the identifier reported by the UE via the second acknowledgement signal, the UE transitions from the sleep state to the on state and transmits the uplink data, and the UE transmits the uplink data on the resource indicated by the second command. If the UE does not receive the second command during the timer operates, or the identifier indicated by the second command is different from the identifier reported by the UE via the second acknowledgement signal, the UE remains in the sleep state and keep operation of the timer or the timer does not restart or update. When the timer expires, the UE enters the off state, and / or the flag of whether the UE is inventoried is inverted, or the flag of whether the UE is inventoried is set to the already inventoried state. Wherein, the third time interval may be a real number greater than or equal to 0.

[0249] (2) The time to enter the sleep state is a position meeting a second time interval after the end position of transmitting the second uplink signal and / or uplink data.

[0250] For example, the UE in the on state starts from the end position of transporting or transmitting the second uplink signal and / or uplink data and a preconfigured or predefined time interval (such as the second time interval), and the UE transitions to the sleep state and starts a timer for indicating the tag state inversion. If the UE receives the first command during the timer operates, and the identifier indicated by the first command is the same as that of the UE, the UE transitions from the sleep state to the on state and transmits the second acknowledgement signal. If the UE does not receive the first command during the timer operates, or the identifier indicated by the received first command is different from the identifier of the UE, the UE remains in the sleep state and keeps operation of the timer or the timer does not restart or update. When the timer expires, the UE enters the off state, and / or the flag of whether the UE is inventoried is inverted, or the flag of whether the UE is inventoried is set to the already inventoried state. Wherein, the second time interval may be a real number greater than or equal to 0.

[0251] In the embodiment of the present disclosure, the first command and the second command refer to the same command, i.e., only one of them needs to be executed. For example, the first command and the second command may be a downlink signal for indicating one or more UEs to feedback data, and the downlink signal includes identifiers for indicating one or more UEs and time-frequency resources for transmitting uplink data. Such operation no longer requires the UE to transmit the second acknowledgement signal. The UE in the on state starts from the end position for transporting or transmitting the second uplink signal and / or uplink data and a preconfigured or predefined time interval (such as the second time interval), and the UE transitions to the sleep state and starts a timer for indicating the tag state inversion. If the UE receives a downlink signal for indicating one or more UEs to feedback data during the timer operates, and the identifier of the UE is the same as the identifier indicated by the downlink signal for indicating one or more UE to feedback data, the UE transitions from the sleep state to the on state, and the UE transmits the uplink data on the determined time-frequency resource. If the UE does not receive a downlink signal for indicating one or more UEs to feedback data during the timer operates, or the identifier indicated by the received downlink signal for indicating one or more UEs to feedback data is different from the identifier of the UE, the UE remains in the sleep state and keeps operation of the timer or the timer does not restart or update. When the timer expires, the UE enters the off state, and / or the flag of whether the UE is inventoried is inverted, or the flag of whether the UE is inventoried is set to the already inventoried state. Wherein, the second time interval may be a real number greater than or equal to 0.

[0252] In the embodiment of the present disclosure, the first uplink signal is transmitted during the on state of UE, and the first uplink signal is used for random access. The UE may enter the sleep state in the case that the first acknowledgement signal is not received, or in the case that the first acknowledgement signal is received but the first acknowledgement signal does not include the information bits of the first uplink signal. The first acknowledgement signal is used to confirm that the first uplink signal is received in the random access process.

[0253] Optionally, not receiving the first acknowledgement signal comprises: not receiving the first acknowledgement signal in a first time interval after the end position of transmitting the first uplink signal.

[0254] For the embodiments of the present disclosure, the non-exhaustive aspects can be found in the introduction above and will not be repeated here.

[0255] In the embodiment of the present disclosure, at least one downlink signal is identified in at least one of the following ways.

[0256] (1) An association relationship between a downlink signal and a predefined sequence.

[0257] For example, the UE may determine the type of the received downlink signal through a mapping relationship between the predefined sequence and at least one downlink signal (e.g., the first downlink signal, or the first acknowledgement signal, or the first command, or the second command, or the first signaling or the second signaling). Wherein, each downlink signal corresponds to a unique predefined sequence. The UE may determine the received sequence by blind detection and determine the type of the received downlink signal through the mapping relationship, i.e., which downlink signal among at least one downlink signal is received.

[0258] (2) A downlink signal type indication domain of the downlink signal.

[0259] For example, the UE may determine the type of the downlink signal by decoding the downlink signal type indication domain of the downlink signal. Optionally, the downlink signal type indication domain may comprise Cyclic Redundancy Check (CRC) check bits.

[0260] (3) Information bits of the first second-predetermined bit number of the downlink signal.

[0261] For example, the UE may determine the type of the downlink signal by decoding the first C information bits of the downlink signal. Wherein, C is a predefined or preconfigured value, and C is a real number greater than 0. Optionally, the first C information bits may comprise the CRC check bits.

[0262] Optionally, if the downlink signal type indication domain or the first C information bits comprise CRC bits, the UE may decode correctly and determine that the received signal is a predefined signal, and the probability of false detection is low. If the UE decodes the downlink signal type indication domain and determines that the received downlink signal is a downlink signal that can be received in the current state, the UE expects to receive or perform the downlink signal. If the UE decodes the downlink signal type indication domain and determines that the received downlink signal is a downlink signal that cannot be received in the current state, the UE does not receive the downlink signal.

[0263] Optionally, in the case that the downlink signal type indication domain or the information bits of the first second-predetermined bit number do not comprise the CRC bits, the behavior of the UE may include a combination of one or more of the following:

[0264] (1) If the identified downlink signal does not belong to the downlink signal that can be received (the UE in the on state or the sleep state or the off state), the UE does not expect to receive the downlink signal.

[0265] (2) If the identified downlink signal does not belong to the downlink signal that can be received (the UE in the on state or the sleep state or the off state), the UE still expects to receive the downlink signal. If the bit length of the received downlink signal is consistent with that of one downlink signal that can be received, the UE determines that the received downlink signal is a downlink signal that can be received, and the UE performs an indication of the received downlink signal. If the bit length of the received downlink signal is inconsistent with the bit length of all the downlink signals that can be received, the UE drops the received downlink signal and / or does not perform the indication of the received downlink signal.

[0266] (3) If the downlink signal identified by the UE belongs to the downlink signal that can be received (the UE in the on state or the sleep state or the off state), the UE expects to receive and perform the downlink signal.

[0267] (4) If the identified downlink signal belongs to the downlink signal that can be received (the UE in the on state or the sleep state or the off state), and if the bit length of the received downlink signal is inconsistent with the bit length of the identified downlink signal, the UE drops the bit length of the received downlink signal and / or does not perform an indication of the bit length of the received downlink signal. If the bit length of the received downlink signal is consistent with the bit length of the identified downlink signal, the UE expects to receive and perform the downlink signal.

[0268] (5) If the identified downlink signal belongs to the downlink signal that can be received (the UE in the on state or the sleep state or the off state), and if the bit length of the received downlink signal exceeds the bit length of the identified downlink signal, drops the received information bits, and / or no longer expects to receive information bits that exceed the bit length of the identified downlink signal. Such operation may reduce the power consumption caused by the UE receiving the signals that are incorrectly identified.

[0269] (6) If the identified downlink signal belongs to the downlink signal that can be received (the UE in the on state or the sleep state or the off state), and if the bit length of the received downlink signal is inconsistent with the bit length of the identified downlink signal, and the bit length of the received downlink signal is consistent with that of one downlink signal that can be received, performing the indication of the received downlink signal.

[0270] In the embodiment of the present disclosure, at least one downlink signaling may correspond to a group of users.

[0271] In an optional implementation, the UE receives the first command, and acquire identifiers for identifying a group of UEs and the time-frequency resource configuration information for transmitting the second acknowledgement signal. If the identifier of the UE is the same as the identifier indicated by the first command, the UE enters the on state, and transmits the second acknowledgement signal or an uplink data signal on the determined time-frequency resource depending on the association relationship between the UE identifier and the time-frequency resource. If the identifier of the UE is different from the identifier indicated by the first command, the UE remains in the sleep state and keeps operation of the timer or the timer does not restart or not update.

[0272] In another optional implementation, the UE receives the first command, and acquires identifiers for identifying a group of UEs and the time-frequency resource configuration information for transmitting the second acknowledgement signal. If the identifier of the UE is the same as the identifier indicated by the first command, the UE enters the on state, and transmits the second acknowledgement signal on the determined time-frequency resource depending on the association relationship between the UE identifier and the time-frequency resource. The UE receives the second command, and acquires identifiers for indicating a group of UEs to perform data reporting and time-frequency resource configuration information of the uplink data signal. If the second command comprises the information bits of the second acknowledgement signal transmitted by the UE, the UE transmits the uplink data signal on the determined time-frequency resource depending on the association relationship between the UE identifier and the time-frequency resource.

[0273] In an optional implementation, the identifier indicated by the first command may be the first X+i bits of the UE-specific index or ID, wherein i is a predefined real number, and i is an integer greater than or equal to 0. For example, the identifier may be the first X+i bits of the International Mobile Subscriber Identity (IMSI). If the first X+i bits of the IMSI of the UE and the identifier are the same, the UE feeds back the first acknowledgement signal or transmits the uplink data signal on the indicated time-frequency resource position. This way implements the division of the UEs that have been inventoried into smaller groups of UEs and implements the transmitting of group commands to smaller groups of UEs.

[0274] In another optional implementation, the identifier indicated by the first command may be S*second random number, wherein S1 may be a predefined real number, or S1 may be implemented depending on the base station and S1 is an integer greater than or equal to 1, and the second random number may be a random number transmitted in the first uplink signal. The UE acquires the information bits of the UE identifier indicated by the first command in the corresponding domain, and depending on the length of the second random number from MSB to LSB, information bits per second random number length is a second random number, and so on, the UE may acquire S1 second random numbers indicated by the first command. This way is used to uniquely indicate S1 UEs. Wherein, the length of the second random number is predefined.

[0275] In yet another optional implementation, the identifier indicated by the first command may be the S2*UE-specific index or ID, and the UE-specific index or ID is the UE index or ID reported by the UE via the second uplink signal. This way is used to uniquely indicate S2 UE. The UE acquires the information bits of the UE identifier indicated by the first command in the corresponding domain, and depending on the length of the UE index or ID from MSB to LSB, information bits per UE index or ID length is one UE index or ID, and so on, and the UE may acquire S2 UE indexes or IDs indicated by the first command.

[0276] In an optional implementation, the identifier of the UE being the same as the identifier indicated by the first command may be that the first X+i bits of the identifier of the UE are the same as the identifier indicated by the first command, or that the second random number generated by the UE is the same as one of the identifiers indicated by the first command. The identifier of the UE being different from the identifier indicated by the first command may be that the first X+i bits of the identifier of the UE are different from the identifier indicated by the first command, or that the second random number generated by the UE is different from any one of the identifiers indicated by the first command.

[0277] In an optional implementation, the second acknowledgement signal transmitted by the UE may comprise a truncated UE index or ID, e.g., the remaining information bits after removing the first X+i bits from the UE index or ID. Or, the second acknowledgement signal transmitted by the UE may comprise a random number different from the random number transmitted in the first uplink signal.

[0278] In an optional implementation, the time-frequency resource configuration information for transmitting the second acknowledgement signal indicated by the first command and / or the time-frequency resource configuration information for transmitting the uplink data signal indicated by the second command may include a combination of one or more of the following.

[0279] (1) The time interval from the end position of the first command and / or the second command to a time domain resource transmission position and / or the bit length indicating the time interval. Wherein, the mapping relationship between the time interval and the information bits indicating the time domain interval is predefined, and the bit length of the time interval may be predefined or may be configured by the first command and / or the second command. The UE determines the bit position in the information bits of the first command corresponding to the information bits indicating the indicated time interval depending on the time interval indicated by the number of bits , and determines a value of the time interval based on the mapping relationship between the time interval and the information bits indicating the time domain interval. Depending on the time interval and the end position of the received first command and / or the second command, a start position of the time domain resource for transmitting the second acknowledgement signal and / or the uplink data signal is determined.

[0280] (2) A duration of time domain resources. The UE determines a time domain resource for transmitting the second acknowledgement signal and / or the uplink data signal through a time interval from the end position of the first command and / or the second command to the time domain resource transmission position and a duration of the time domain resource.
