Fig. 1 illustrates an example wireless network 100 in accordance with various embodiments of the present disclosure. The embodiment of the wireless network 100 shown in fig. 1 is for illustration only. Other embodiments of wireless network 100 can be used without departing from the scope of this disclosure.

Wireless network 100 includes a gNodeB (gNB) 101, a gNB 102, and a gNB 103.gNB 101 communicates with gNB 102 and gNB 103. The gNB101 also communicates with at least one Internet Protocol (IP) network 130, such as the internet, a proprietary IP network, or other data network.

Depending on the network type, other well-known terms can be used instead of "gnnodeb" or "gNB", such as "base station" or "access point". For convenience, the terms "gNodeB" and "gNB" are used in this patent document to refer to network infrastructure components that provide wireless access for remote terminals. Also, other well-known terms, such as "mobile station", "subscriber station", "remote terminal", "wireless terminal", or "user equipment", can be used instead of "user equipment" or "UE", depending on the network type. For convenience, the terms "user equipment" and "UE" are used in this patent document to refer to a remote wireless device that wirelessly accesses the gNB, whether the UE is a mobile device (such as a mobile phone or smartphone) or what is commonly considered a stationary device (such as a desktop computer or vending machine).

gNB 102 provides wireless broadband access to network 130 for a plurality of first User Equipments (UEs) within coverage area 120 of gNB 102. The plurality of first UEs include: a UE 111, which may be located in a Small Enterprise (SB); a UE 112, which may be located in an enterprise (E); UE 113, which may be located in a WiFi Hotspot (HS); a UE 114, which may be located in a first residence (R); a UE 115, which may be located in a second residence (R); the UE 116, may be a mobile device (M), such as a cellular phone, wireless laptop, wireless PDA, or the like. gNB 103 provides wireless broadband access to network 130 for a plurality of second UEs within coverage area 125 of gNB 103. The plurality of second UEs include UE 115 and UE 116. In some embodiments, one or more of the gNBs 101-103 can communicate with each other and with UEs 111-116 using 5G, long Term Evolution (LTE), LTE-A, wiMAX, or other advanced wireless communication technology.

The dashed lines illustrate the approximate extent of coverage areas 120 and 125, which are shown as approximately circular for purposes of illustration and explanation only. It should be clearly understood that coverage areas associated with the gNB, such as coverage areas 120 and 125, can have other shapes, including irregular shapes, depending on the configuration of the gNB and variations in the radio environment associated with natural and artificial obstructions.

As described in more detail below, one or more of gNB101, gNB 102, and gNB 103 include a 2D antenna array as described in embodiments of the present disclosure. In some embodiments, one or more of gNB101, gNB 102, and gNB 103 support codebook design and structure for systems with 2D antenna arrays.

Although fig. 1 illustrates one example of a wireless network 100, various changes can be made to fig. 1. For example, wireless network 100 can include any number of gnbs and any number of UEs in any suitable arrangement. Also, the gNB101 can communicate directly with any number of UEs and provide those UEs with wireless broadband access to the network 130. Similarly, each of gnbs 102-103 can communicate directly with network 130 and provide UEs direct wireless broadband access to network 130. Further, the

gnbs

101, 102, and/or 103 can provide access to other or additional external networks, such as external telephone networks or other types of data networks.

Fig. 2a and 2b illustrate example wireless transmit and receive paths according to the present disclosure. In the following description, transmit path 200 can be described as being implemented in a gNB (such as gNB 102), while receive path 250 can be described as being implemented in a UE (such as UE 116). However, it should be understood that the receive path 250 can be implemented in the gNB and the transmit path 200 can be implemented in the UE. In some embodiments, receive path 250 is configured to support codebook design and structure for systems with 2D antenna arrays as described in embodiments of the present disclosure.

The transmit path 200 includes a channel coding and modulation block 205, a serial-to-parallel (S-to-P) block 210, an N-point Inverse Fast Fourier Transform (IFFT) block 215, a parallel-to-serial (P-to-S) block 220, an add cyclic prefix block 225, and an up-converter (UC) 230. Receive path 250 includes a down-converter (DC) 255, a remove cyclic prefix block 260, a serial-to-parallel (S-to-P) block 265, an N-point Fast Fourier Transform (FFT) block 270, a parallel-to-serial (P-to-S) block 275, and a channel decode and demodulation block 280.

In transmit path 200, a 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 with Quadrature Phase Shift Keying (QPSK) or Quadrature Amplitude Modulation (QAM), to generate a sequence of frequency domain modulation symbols. A serial-to-parallel (S-to-P) block 210 converts (such as demultiplexes) the serial modulation symbols into parallel data in order to generate N parallel symbol streams, where N is the IFFT/FFT point number used in the gNB 102 and UE 116. N-point IFFT block 215 performs IFFT operations on the N parallel symbol streams to generate a time-domain output signal. Parallel-to-serial block 220 converts (such as multiplexes) the parallel time-domain output symbols from N-point IFFT block 215 to generate a serial time-domain signal. Add cyclic prefix block 225 inserts a cyclic prefix into the time domain signal. Upconverter 230 modulates (such as upconverts) the output of add cyclic prefix block 225 to an RF frequency for transmission over a wireless channel. The signal can also be filtered at baseband before being converted to RF frequency.

The RF signal transmitted from the gNB 102 reaches the UE 116 after passing through the radio channel, and the reverse operation to that at the gNB 102 is performed at the UE 116. Downconverter 255 downconverts the received signal to baseband frequency and remove cyclic prefix block 260 removes the cyclic prefix to generate a serial time-domain baseband signal. Serial-to-parallel block 265 converts the time-domain baseband signal to parallel time-domain signals. The N-point 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 signals to a sequence of modulated data symbols. Channel decode and demodulation block 280 demodulates and decodes the modulated symbols to recover the original input data stream.

Each of the gnbs 101-103 may implement a transmit path 200 similar to transmitting to the UEs 111-116 in the downlink and may implement a receive path 250 similar to receiving from the UEs 111-116 in the uplink. Similarly, each of UEs 111-116 may implement a transmit path 200 for transmitting in the uplink to gnbs 101-103 and may implement a receive path 250 for receiving in the downlink from gnbs 101-103.

Each of the components in fig. 2a and 2b can be implemented using hardware alone, or using a combination of hardware and software/firmware. As a specific example, at least some of the components in fig. 2a and 2b may be implemented in software, while other components may be implemented in configurable hardware or a mixture of software and configurable hardware. For example, FFT block 270 and IFFT block 215 may be implemented as configurable software algorithms, where the value of the number of points N may be modified depending on the implementation.

Further, although described as using an FFT and IFFT, this is merely illustrative and should not be construed as limiting the scope of the 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 the value of the variable N may be any integer (such as 1,2, 3, 4, etc.) for DFT and IDFT functions, and any integer that is a power of 2 (such as 1,2, 4, 8, 16, etc.) for FFT and IFFT functions.

Although fig. 2a and 2b show examples of wireless transmission and reception paths, various changes may be made to fig. 2a and 2 b. For example, the various components in fig. 2a and 2b can be combined, further subdivided, or omitted, and additional components can be added according to particular needs. Also, fig. 2a and 2b are intended to illustrate examples of the types of transmit and receive paths that can be used in a wireless network. Any other suitable architecture can be used to support wireless communications in a wireless network.

Fig. 3a illustrates an example UE 116 according to this disclosure. 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 configurations. However, UEs have a wide variety of configurations, and fig. 3a does not limit the scope of the present disclosure to any particular implementation of a UE.

The UE 116 includes an antenna 305, a Radio Frequency (RF) transceiver 310, transmit (TX) processing circuitry 315, a microphone 320, and Receive (RX) processing circuitry 325. The UE 116 also includes a speaker 330, a processor/controller 340, an input/output (I/O) interface 345, input device(s) 350, a display 355, and a memory 360. Memory 360 includes an Operating System (OS) 361 and one or more applications 362.

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

TX processing circuit 315 receives analog or digital voice data from microphone 320 or other outgoing baseband data (such as network data, e-mail, or interactive video game data) from processor/controller 340. TX processing circuitry 315 encodes, multiplexes, and/or digitizes the outgoing baseband data to generate a processed baseband or IF signal. RF transceiver 310 receives the outgoing processed baseband or IF signals from TX processing circuitry 315 and upconverts the baseband or IF signals to RF signals, which are transmitted via antenna 305.

The processor/controller 340 can include one or more processors or other processing devices and executes the OS 361 stored in the memory 360 in order to control overall operation of the UE 116. For example, processor/controller 340 may be capable of controlling the reception of forward channel signals and the transmission of reverse channel signals by RF transceiver 310, RX processing circuitry 325, and TX processing circuitry 315 in accordance with well-known principles. In some embodiments, processor/controller 340 includes at least one microprocessor or microcontroller.

The processor/controller 340 can also execute other processes and programs resident in the memory 360, such as operations for channel quality measurement and reporting for systems having 2D antenna arrays as described in embodiments of the present disclosure. Processor/controller 340 is capable of moving data into and out of memory 360 as needed to perform a process. In some embodiments, processor/controller 340 is configured to execute applications 362 based on OS 361 or in response to signals received from the gNB or the operator. The processor/controller 340 is also coupled to an I/O interface 345, where the I/O interface 345 provides the UE 116 with the ability to connect to other devices, such as laptop computers and handheld computers. I/O interface 345 is the communication path between these accessories and processor/controller 340.

The processor/controller 340 is also coupled to input device(s) 350 and a display 355. The operator of the UE 116 can input data into the UE 116 using the input device(s) 350. Display 355 may be a liquid crystal display or other display capable of presenting text and/or at least limited graphics (such as from a website). A memory 360 is coupled to the processor/controller 340. A portion of memory 360 can include Random Access Memory (RAM), while another portion of memory 360 can include flash memory or other read-only memory (ROM).

Although fig. 3a shows one example of the UE 116, various changes can be made to fig. 3 a. For example, the various components in FIG. 3a can be combined, further subdivided, or omitted, and additional components can be added according to particular needs. As a particular example, the processor/controller 340 can be divided into multiple processors, such as one or more Central Processing Units (CPUs) and one or more Graphics Processing Units (GPUs). Also, while fig. 3a shows the UE 116 configured as a mobile phone or smart phone, the UE can be configured to operate as other types of mobile or fixed devices.

Fig. 3b illustrates an example gNB 102 according to this disclosure. The embodiment of the gNB 102 shown in fig. 3b is for illustration only, and the other gnbs of fig. 1 can have the same or similar configuration. However, the gNB has a wide variety of configurations, and fig. 3b does not limit the scope of the present disclosure to any particular implementation of the gNB. It should be noted that gNB101 and gNB 103 can include the same or similar structure as gNB 102.

As shown in fig. 3b, the gNB 102 includes multiple antennas 370a-370n, multiple RF transceivers 372a-372n, transmit (TX) processing circuitry 374, and Receive (RX) processing circuitry 376. In certain embodiments, one or more of the plurality of antennas 370a-370n comprises a 2D antenna array. The gNB 102 also includes a controller/processor 378, a memory 380, and a backhaul or network interface 382.

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

TX processing circuitry 374 receives analog or digital data (such as voice data, network data, e-mail, or interactive video game data) from controller/processor 378. TX processing circuitry 374 encodes, multiplexes, and/or digitizes the outgoing baseband data to generate a processed baseband or IF signal. RF transceivers 372a-372n receive outgoing processed baseband or IF signals from TX processing circuitry 374 and upconvert the baseband or IF signals into RF signals for transmission via antennas 370a-370 n.

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 reverse channel signals through the RF transceivers 372a-372n, RX processing circuitry 376, and TX processing circuitry 374 according to well-known principles. The controller/processor 378 can also support additional functions, such as higher-level wireless communication functions. For example, controller/processor 378 can perform a Blind Interference Sensing (BIS) process, such as by a BIS algorithm, and decode the received signal minus the interfering signal. Controller/processor 378 may support any of a wide variety of other functions in the gNB 102. In some embodiments, controller/processor 378 includes at least one microprocessor or microcontroller.

Controller/processor 378 is also capable of executing programs and other processes resident in memory 380, such as a base OS. 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, controller/processor 378 supports communication between entities such as a web RTC. Controller/processor 378 can move data into and out of memory 380 as needed to perform a process.

Controller/processor 378 is also coupled to a backhaul or network interface 382. Backhaul or network interface 382 allows gNB 102 to communicate with other devices or systems over a backhaul connection or over a network. Backhaul or network interface 382 can support communication via any suitable wired or wireless connection(s). For example, when gNB 102 is implemented as part of a cellular communication system (such as one supporting 5G or new radio access technologies or NR, LTE or LTE-a), backhaul or network interface 382 can allow gNB 102 to communicate with other gnbs over wired or wireless backhaul connections. When gNB 102 is implemented as an access point, backhaul or network interface 382 can allow gNB 102 to communicate with a larger network (such as the internet) via a wired or wireless local area network or via a wired or wireless connection. Backhaul or network interface 382 includes any suitable structure to support communication via a wired or wireless connection, such as an ethernet or RF transceiver.

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

As described in more detail below, the transmit and receive paths of gNB 102 (implemented using RF transceivers 372a-372n, TX processing circuitry 374, and/or RX processing circuitry 376) support aggregated communication with FDD and TDD cells.

Although fig. 3b shows one example of a gNB 102, various changes may be made to fig. 3 b. For example, the gNB 102 can include any number of each of the components shown in fig. 3 a. As a particular example, the access point can include a number of backhauls or network interfaces 382 and the controller/processor 378 can support routing functions to route data between different network addresses. As another particular example, although shown as including a single instance of TX processing circuitry 374 and a single instance of RX processing circuitry 376, gNB 102 can include multiple instances of each (such as one for each RF transceiver).

It is understood that the solutions provided in the embodiments of the present application can be applied to, but are not limited to, the wireless networks described above.

The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings. The text and figures in the following description are provided by way of example only to assist the reader in understanding the present disclosure. They are not intended, nor should they be construed, as limiting the scope of the disclosure in any way. While certain embodiments and examples have been provided, it will be apparent to those skilled in the art, based on the disclosure herein, that changes may be made to the embodiments and examples shown without departing from the scope of the disclosure.

In a wireless communication network, in order to enhance network coverage, base station to UE (User Equipment) and UE to base station information (data and/or control information, which may also be referred to as control signaling) may be forwarded by a network device. The name of the network device that forwards information is not limited in this embodiment, and may be referred to as a booster (Repeater), an intelligent booster (Smart Repeater), a relay device, or another name. For convenience of description, in the embodiments of the present application, a booster (Repeater) is described as an example.

Fig. 4 shows a schematic structural diagram of a wireless communication system according to an embodiment of the present application, as shown in fig. 4, data and/or control signaling sent by a UE to a base station may be sent to the base station through an enhancer, and data and/or control signaling sent by the base station to the UE may be sent to the UE through the enhancer.

The embodiment of the application provides a communication method for better meeting communication requirements and improving communication performance, and based on the method, the performance of receiving and/or sending data and/or control information by electronic equipment such as an enhancer and UE can be effectively improved.

The method of the embodiment of the application can be applied to a communication system in which the data and the control information received by the Repeater are directly forwarded on the same time-frequency resource without demodulation and decoding, and can also be applied to a system in which the received data and the control information are demodulated and decoded and then forwarded on other resources after the Repeater receives the data and the control information.

In an optional case, the booster works in a time division multiplexing manner, that is, in a time period, the booster receives downlink data and/or downlink control information from the base station, and then the booster forwards the received downlink data and/or downlink control information to the UE, where the time period may be referred to as a downlink time period; in another time period, the booster receives uplink data and/or uplink control information from the UE, and then forwards the received uplink data and/or uplink control information to the base station, which may be referred to as an uplink time period; while in yet another time period, the booster may also stop working, as in the example shown in fig. 5, the booster receives downlink information (downlink data and downlink control information) from the base station and transmits it to the UE in the downlink time period S1, stops working in the time period S2, and receives uplink information from the UE and transmits it to the base station in the time period S3.

Optionally, the beam for receiving the downlink data and/or the downlink control information from the base station by the booster and the beam for receiving the uplink data and/or the uplink control information from the UE by the booster may be different, so as to better improve the receiving performance of the booster. The beam for transmitting the uplink data and/or the uplink control information to the base station by the booster and the beam for transmitting the downlink data and/or the downlink control information to the UE by the booster can be different, so that the receiving performance of the booster can be better improved.

Of course, in practical applications, optionally, the beam for the booster to receive information (data and/or control information) from the base station and the beam for the booster to receive information from the UE may also be the same, and the beam for the booster to transmit information to the base station and the beam for the booster to transmit information to the UE may also be the same.

For convenience of description, a beam used by the booster for receiving information may be referred to as a reception beam, and a beam used by the booster for transmitting information may be referred to as a transmission beam. Wherein the receive beam comprises a beam used by the booster to receive information from the UE and the transmit beam comprises a beam used by the booster to transmit information to the UE.

The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments. These several specific embodiments may be combined with each other below, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.

Fig. 6 shows a flowchart of a communication method provided in this embodiment, where the method may be executed by a first network device (any network device in a communication system), and names of the network devices are not limited in this embodiment, such as may be referred to as a relay, an enhancer, or other names, and the following description takes an enhancer as an example. As shown in fig. 6, the method may include:

step S610: receiving first information, wherein the first information is used for configuring at least one first beam for transmitting information;

step S620: determining at least one first beam according to the first information;

step S630: the transmission of information is performed based on the determined at least one first beam.

The name of the first information is not limited in the embodiment of the present application, and may be referred to as configuration information, beam configuration, indication information, or other names. The first information may be added with new information (or message) or may be an improvement on existing information of the existing communication system, for example, a new field may be added with the existing message, and the first information is indicated by the field.

The first information is used for the booster to determine a beam used by the booster to transmit and/or receive information, and the form of the content included in the first information is not limited in the embodiments of the present application. For example, the first information may include identification information of the transmission beam and/or the reception beam (such as a number of the beam, direction information of the beam, or angle information of the beam), and the enhancer may determine the first beam according to the identification information. For another example, the first information may include an indicator value of a transmission beam and/or a reception beam, where the indicator value and the beam have a correspondence (which may be protocol-agreed or determined by the enhancer through receiving higher layer information or physical layer information, etc.), and the enhancer may determine the beam used for transmitting information according to the indicator value and the correspondence in the first information.

The first information is further used to indicate that each first beam is a receive beam or a transmit beam.

That is, the first information may further include indication information of a beam type of each first beam, where the information is used to indicate whether the beam is a transmission beam or a reception beam, and the booster may know, according to the information, whether the beam indicated by the base station is a beam used to transmit information to the UE or a beam used to receive information transmitted by the UE. The specific form of the indication information is not limited in the embodiments of the present application. For example, the first information indicates a first beam, and the first information may further include identification information of a beam type, where the identification information indicates that the beam is a receive beam or a transmit beam, for example, identification information 1 indicates a receive beam, and identification information 0 indicates a transmit beam. For another example, the first information indicates two beams, and the first information may further include identification information of beam types of the indicated two beams, for example, if the identification information is 00, it indicates that both the two beams are transmission beams, if the identification information is 11, it indicates that both the two beams are reception beams, and if the identification information is 01, it indicates that the beam used earlier is a transmission beam and the beam used later is a reception beam. Of course, other indication means are also possible.

In an optional embodiment of the present application, the first information includes a first indication value; the determining at least one first beam according to the first information includes:

at least one first beam is determined based on the first indicator value.

That is, the first indicator value is used to indicate the at least one beam, and the beam indicated by the indicator value is the beam used by the booster to transmit information.

Optionally, determining at least one first beam according to the first indicator value may include:

determining at least one first beam according to the first indicated value and the first mapping relation; wherein the first mapping relationship comprises: each indicator value in a first set of indicator values corresponds to at least one beam corresponding to the indicator value.

It is to be understood that the first set of indicator values may include one or more indicator values, where the one or more indicator values include a first indicator value, each indicator value corresponds to at least one beam, and the at least one beam corresponding to the first indicator value is a beam used by the booster to transmit information.

The method for obtaining the first mapping relationship is not limited in the embodiment of the present application. For example, the configuration may be performed through higher layer signaling, may be indicated through system information, and may also be obtained through other implicit manners. As an example, an alternative form of the first mapping relationship is shown in Table 1.

Beam indication information value	Wave beam
		00	Wave beam one
01	Wave beam two
		10	Wave beam three
11	Wave beam four

Table 1: correspondence between beam indication information and beam

In this example, each indication value in the first indication value set may occupy two bits, each beam indication information value (also referred to as a beam indication index value) in table 1 is each indication value in the first indication value set, in this example, the number of the indication values in the first indication value set is 4, each indication value corresponds to at least one beam, for example, a beam corresponding to the indication value "00" is a beam one, and a beam corresponding to the indication value "01" is a beam two. If the first indicator value in the first information received by the booster is "10", it can be determined that the first beam is beam three according to the first indicator value and the mapping relation.

The booster may determine, based on the received first information, a first beam that the booster uses for information transmission. The information source of the first information is not limited in this embodiment, and may be sent to the booster by the high layer through the base station, or configured by the base station to the booster.

Optionally, the receiving the first information may include:

receiving a first signaling, wherein the first signaling carries the first information;

wherein the first signaling comprises at least one of:

high layer signaling, medium access layer signaling, physical layer signaling.

That is, the first Information may be configured through higher layer signaling, media Access Control (MAC) layer signaling, or physical layer signaling (i.e., downlink Control Information (DCI)).

As an alternative, the first signaling may be physical layer signaling, that is, the base station transmits the beam configuration to the booster by transmitting DCI, and the booster acquires the first information by receiving the DCI transmitted by the base station.

In an optional embodiment of the application, the receiving the first signaling may include at least one of:

acquiring first signaling from a unique search space corresponding to a first network device (namely, an enhancer);

and acquiring the first signaling from the public search space corresponding to the first network equipment.

As an alternative implementation, the enhancer may correspond to a specific Search space, which is not limited in this application, and may be referred to as USS (UE-specific Search), for example, and it is understood that the USS is for the enhancer. In this way, the transmit beam of one booster and/or the receive beam of a booster may be notified in one DCI. The booster may receive this DCI information in its specific search space (i.e., the channel on which the booster receives the DCI (which may be referred to as the booster beam indication channel or other name) may be the channel carrying the booster specific DCI), determine its own transmit beam and/or receive beam from the information in the DCI.

The number of bits of the beam indication information (i.e., the first information) in the DCI may be L bits (L is a positive integer), for example, the value of L may be preset by a protocol or configured by high layer signaling, or may be determined by the number B of beams that needs to be indicated (i.e., the number of the at least one first beam), for example, L may be rounded up to (log 2 (B)).

As an alternative implementation, the DCI may also be transmitted in a common search space corresponding to the first network device, that is, a search space corresponding to a group of boosters. With this approach, a set of transmit beams of the booster (usually more than one) and/or receive beams of the booster can be notified in one DCI, which can save resources occupied by the DCI.

The DCI including the first information is transmitted in the common search space, which may be referred to as group-common DCI, and a group of intensifiers may receive the DCI, and then each of the intensifiers determines its corresponding first information in the DCI according to the DCI, and determines its own transmit beam and/or receive beam according to its corresponding first information. For example, the DCI may include M information blocks (i.e., M first information, where M is a positive integer, M is greater than or equal to 1, and a specific value may be preset by a protocol or configured by a higher layer signaling), and one information block indicates a beam for one enhancer, that is, the DCI may be used to configure beams corresponding to the M enhancers, and each enhancer may determine its own transmit beam and/or receive beam according to corresponding information in the DCI.

In an optional embodiment of the application, the receiving the first information includes:

receiving second information, wherein the second information may include at least one piece of first information, the second information corresponds to a group of network devices, and one piece of first information is used for determining a beam used by a network device corresponding to the first information in the group of network devices to transmit information; the determining at least one first beam according to the first information includes:

determining first information corresponding to the first network equipment in the second information according to the identifier of the first network equipment;

at least one first beam is determined according to the determined first information.

As can be seen from the foregoing description, the second information (e.g., the group common DCI) may carry beam indication information of at least one booster (i.e., the group of network devices), and the group of network devices includes the first network device, at this time, after receiving the second information, the current booster (i.e., the first network device) may determine, according to the device identifier of the current booster, the beam indication information (first information) corresponding to the current booster in the second information, and determine, according to the beam indication information of the current booster, at least one first beam used for transmitting information.

Optionally, the first information may include at least one second information and an identifier of the network device corresponding to each second information, and each enhancer may determine its own second information directly according to its own identifier. Or the first information includes a plurality of second information, and implies a corresponding relationship between each second information and the corresponding second network device, for example, a position relationship of the plurality of second information included in the first information implies a corresponding relationship between each second information and an identifier of the corresponding booster, and each booster may determine, according to the identifier of the booster, the first information at a position corresponding to the identifier in the first information as its own first information. For example, the second information includes two information blocks, each information block is a first information, and the field positions of the two information blocks in the second information implicitly include which booster the information block corresponds to, for example, an information block before the field corresponds to the booster identified as a, and an information block after the field corresponds to the booster identified as b, so that after receiving the first information, the booster identified as a can determine that the information block before the field corresponds to its own information block, and can determine the corresponding beam according to the information block.

The specific form of the identifier of the network device, that is, the Identifier (ID) of the booster is not limited in this embodiment, and may be a unique identifier of the booster in the entire network, or an identifier of the booster in a booster group (at least one booster corresponding to the first information) to which the booster belongs, for example, the first information includes 3 pieces of second information, that is, 3 boosters, where the 3 boosters are a group of boosters, each booster in the group of boosters may correspond to one intra-group number (for example, the numbers are 1,2, and 3, respectively), and the number may be used as a booster identifier.

In an optional embodiment of the present application, the method may further include:

the determining, according to the identifier of the first network device, the first information corresponding to the first network device in the second information includes:

and determining first information corresponding to the first network equipment in the second information according to the identifier of the first network equipment and the first configuration information.

The embodiment of the present application is not limited to the manner of acquiring the first configuration information. Optionally, the first configuration information may be configured to the booster through higher layer signaling, or may be configured to the booster through system message, physical layer signaling, or other signaling. After receiving the second information, the current booster may search, according to the device identifier thereof, first information corresponding to the booster itself in the correspondence (i.e., the correspondence configured by the first configuration information), and determine a transmission beam and/or a reception beam to be used by the booster itself according to the searched first information.

In an alternative embodiment of the present application, the method further comprises: determining a time of use of the at least one first beam;

transmitting information based on the determined at least one first beam, comprising:

the transmission of information is performed based on the determined at least one first beam and the time of use of the at least one beam.

For the booster, the use time of a beam refers to the effective time of a beam, that is, the time when the booster can use the beam. Optionally, the usage time of a beam may include the start time (i.e., S) and duration (denoted as T) of the beam. The start time is the start time when a beam can be used, and the duration is the effective duration during which the beam can be used. The time unit using time is not limited in the embodiments of the present application, and may include, but is not limited to, an OFDM (Orthogonal Frequency Division Multiplexing) symbol, a slot, a micro-slot, or others.

Optionally, when the second information includes a plurality of first information corresponding to a plurality of boosters, the use time of the at least one first beam may be determined by at least one of:

in the method a, according to the determined first information, the use time of at least one first beam is determined, wherein each piece of first information in the second information is also used for determining the use time of the beam used by the network device corresponding to the first information;

For the method a, each piece of first information included in the second information may be used to configure at least one beam used by the booster corresponding to the first information to transmit information, and may also indicate a use time of the at least one beam corresponding to the first information. For example, the second information includes M information blocks (i.e., the first information), each information block corresponds to one booster, and each information block indicates at least one beam used by one booster to transmit information and a use time of the beam.

As for the method b, the second information may further include, in addition to the at least one first information, time indication information indicating time information of a beam used by the group of network devices to transmit information. For example, the second information includes M +1 information blocks, where M information blocks are M first information blocks, another information block is time indication information, each of the M information blocks indicates at least one beam used by one booster to transmit information, and the time indication information indicates the use time of the beams corresponding to the M boosters, that is, the time indication information of the M boosters may be the same.

As for the method c, the second information further includes a plurality of time indication information, each time indication information corresponds to one network device in the group of network devices, that is, the time indication information corresponds to the network devices one to one. The current booster, i.e. the first network device, may determine its corresponding time indication information from the plurality of time indication information according to its device identifier. Optionally, determining, according to the identifier of the first network device, second time indication information corresponding to the first network device in the second information may include at least one of the following:

determining second time indication information corresponding to the first network device according to the identifier of the first network device and the first configuration information, wherein the first configuration information is further used for configuring a corresponding relationship between each piece of time indication information in the at least one piece of second time indication information and the identifier of the network device corresponding to the time indication information in the group of network devices;

acquiring second configuration information, where the second configuration information is used to configure a corresponding relationship between each piece of time indication information in the at least one piece of second time indication information and an identifier of a network device corresponding to the time indication information in the group of network devices; and determining second time indication information corresponding to the first network equipment in the second information according to the identifier of the first network equipment and the second configuration information.

In an optional embodiment of the present application, when determining the first information and the second time indication information corresponding to the first network device, the following manner may also be adopted:

determining first information corresponding to the first network equipment in the second information according to the identifier of the first network equipment, and determining second time information corresponding to the first network equipment in at least one piece of second time indication information according to the field position of the determined first information in the second information;

or,

and determining second time indication information corresponding to the first network equipment in the second information according to the identifier of the first network equipment, and determining first information corresponding to the first network equipment in at least one piece of first information according to the field position of the determined second time indication information in the second information.

That is, the first information and the second time indication information corresponding to one network device have a corresponding relationship, and the other can be determined according to one of the first information and the second time indication information. For example, the second information corresponds to M boosters, the second information includes M first information and M second time indication information, and it is determined that 2 nd first information of the M first information is first information corresponding to the first network device according to the identifier of the first network device, and correspondingly, 2 nd time indication information of the M second time indication information is second time indication information corresponding to the first network device.

For modes d and e, the beams and the use times of the beams may be indicated separately, i.e., the second information is used to indicate the beams used by the respective boosters, and the third time indication information/time configuration information independently indicates the use times of the beams used by a group of network devices. It should be noted that, on the premise that there is no logical contradiction, the description of the first time indication information is also applicable to the third time indication information, and the description of the second time indication information is also applicable to the fourth time indication information, which is not described herein again.

It should be noted that, for the manner in which the second information includes one or more first information, one first information may be used to configure at least one beam used by the booster corresponding to the first information to transmit information, and the second information may further include information for indicating each beam type, that is, for indicating whether each beam is a receive beam or a transmit beam. The first network device may determine, according to the received second information, at least one first beam that the first network device may use and a type of each beam of the at least one first beam.

In this embodiment, the transmitting information includes sending information and/or receiving information, and accordingly, the at least one first beam may include at least one of:

at least one transmit beam; at least one receive beam;

accordingly, the information transmitted based on the at least one first beam may include at least one of uplink information and downlink information, wherein the uplink information may include at least one of uplink data and uplink control information, and the downlink information includes at least one of downlink data and downlink control information.

The transmission beam may be a beam used by the booster to transmit information (data and/or control information) to the UE, and correspondingly, the downlink information is information transmitted by the booster to the UE through the transmission beam. The receive beam may refer to a beam in which the booster receives information transmitted by the UE, and accordingly, the uplink information is information received by the booster from the UE through the receive beam. The first information may include indication information of a beam type indicating whether each of the indicated at least one first beam is a reception beam or a transmission beam. For example, the first information indicates one first beam and indicates that the type of the beam is a receiving beam, or the first information indicates two first beams and indicates the type of the beam of each of the first beams, for example, beam a is a receiving beam and beam b is a transmitting beam.

Based on the method of the embodiment of the application, the dynamic configuration of the receiving beam and/or the sending beam of the intensifier can be realized based on the first information, so that the intensifier can be more intelligent in receiving and/or sending information, the existing communication mode is improved, the flexible configuration and use of network resources are realized, and the communication requirement is better met.

In an optional embodiment of the present application, for the determined at least one first beam, the usage time of the beam may be further determined by using at least one of:

determining time information of the at least one first beam according to the first information;

acquiring third information, wherein the third information is used for determining the time information of the at least one first beam; determining time information of at least one first beam according to the third information;

correspondingly, the transmitting information based on the determined at least one first beam includes:

and transmitting information according to the at least one first beam and the time information of the at least one first beam.

This alternative of the present application, in addition to enabling flexible configuration of the beams used by the booster, also enables dynamic management of the times of use of the beams.

The configuration of the time information of the beam may be implemented based on the first information, or may be implemented based on the third information, that is, the beam and the time information of the beam may be jointly determined, or may be independently determined. That is, the first information may be used to determine time information of each of the at least one first beam, in addition to configuring the at least one first beam.

The specific manner of determining the time information of the beam through the first information or the third information may be configured as needed. For example, the first information may include a first field for determining a beam and a second field for determining time information of the beam, and at least one first beam used by the booster for transmitting information and the time information of the beam may be determined according to contents of the first field and the second field. The specific obtaining mode of the third information is also not limited in the embodiment of the present application, for example, the enhancer may be determined by receiving a higher layer signaling, a physical layer signaling, or a media access layer signaling, and the third information may also be agreed information, that is, information preset by a protocol.

As can be seen from the foregoing alternative embodiments, the first information may include a first indicator value, and at least one first beam used by the booster for transmitting information may be determined according to the first indicator value and the first mapping relation (see the foregoing description).

Optionally, for the usage time of the at least one first beam (i.e. the time when the beam can be used, which may also be referred to as the effective time), the following manner may be adopted to determine:

acquiring a second indication value, wherein the second indication value is used for configuring the use time of the at least one first beam;

the time of use of the at least one first beam is determined based on the second indication.

Optionally, determining the usage time of the at least one first beam according to the second indication value includes:

determining the service time of at least one first beam corresponding to the second indication value according to the second indication value and the third mapping relation; wherein the third mapping relationship comprises: and the corresponding relation between each indicated value in a third indicated value set and the time information of at least one beam corresponding to the indicated value.

The embodiment of the present application is also not limited to the manner of obtaining the second mapping relationship. For example, the configuration may be performed through higher layer signaling, may be indicated through system information, and may also be obtained through other implicit manners. In practical applications, the second indication value and the first indication value may be the same or different. As an example, an alternative form of the third mapping relationship is shown in Table 2.

Table 2: beam time indication index value and the corresponding relation of starting time (S) and duration (T)

In this example, each of the indicator values may occupy two bits, that is, the indicator values in the third set of indicator values, where the start time and duration of the beam corresponding to the indicator value "00" are S1 and T1, respectively, and the start time and duration of the beam corresponding to the indicator value "01" are S2 and T2, respectively. In conjunction with the second mapping relationship shown in table 2, if the second indication value received by the enhancer is "10", it can be determined that the start time of the first beam indicated by the first information is S3 and the duration is T3.

It should be noted that, in an alternative embodiment of the present application, the time information of the beam may be the use time of the beam, or may be information for determining the use time of the beam. For example, in table two above, the start time S and the duration T may refer to the real start time and duration of the beam, or may be information for determining the start time and duration. For example, the start time may be a time offset of the true start time of a beam with respect to the acquisition time of the first information, and the true start time of the beam may be determined based on the offset and the acquisition time of the first information. Also, the duration may be the actual usage duration of the beam or information used to determine the duration.

The embodiment of the present application is not limited to the manner of obtaining the second indication value, and optionally, the third indication value may be included in the first information, or may be included in the third information, and the obtaining is indicated by the base station through other manners.

As another optional implementation, the determining at least one first beam according to the first information includes:

determining at least one first wave beam corresponding to the first indicator value and time information of the at least one first wave beam according to the first indicator value and the second mapping relation; wherein the second mapping relationship comprises: a corresponding relation among each indicated value in a second indicated value set, at least one beam corresponding to each indicated value and time information of each beam corresponding to each indicated value;

correspondingly, the transmitting information based on at least one first beam includes:

and transmitting information according to the at least one first beam and the using time of the at least one first beam.

And the second indication value set comprises the first indication value. At least one first beam and a beam use time can be simultaneously determined based on the first indicator value.

In this alternative, the time information of the at least one first beam and the at least one beam may be jointly determined, which may save network resources. As an example, an alternative form of the second mapping relationship is shown in Table 3.

Beam indication index value	Wave beam	Starting time (a)S)	Duration (T)
				00	Wave beam one	S1	T1
01	Wave beam two	S2	T2
				10	Wave beam three	S3	T3
11	Wave beam four	S4	T4

Table 3: beam indication information, beam, and correspondence of beam time information

In practical applications, at least one beam corresponding to one booster may be one or multiple beams, and in order to meet application requirements of one or multiple beams, the second mapping relation time information may include time information of each beam corresponding to each indicator value, for example, the beam corresponding to the indicator value "00" is a beam a and a beam B, and the first mapping relation includes time information of the beam a corresponding to the indicator value and time information of the beam B corresponding to the indicator value. Optionally, the second mapping relationship may further include the number of beams (which may be referred to as the number of beams) corresponding to each indication value. The beam indication index value (i.e., the first indicator value) in this example is used to determine both the first beams and the time information for each first beam.

As another alternative, the time information of each beam in the at least one beam corresponding to each first indicator value or second indicator value may or may not be continuous in time, and if the time information is continuous, the second mapping relationship or the third mapping relationship may include a start time (or information for determining the start time) of one beam (for example, a first beam or a last beam in time sequence) and a duration (or information for determining the duration) of each beam in the at least one beam corresponding to each indicator value. As an alternative example, an alternative form of the second mapping relationship is shown in Table 4-1.

TABLE 4-1

In this example, the number of beams corresponding to different beam indication index values may be one or multiple, and when multiple (two or more) beams are corresponding, the time information of the multiple beams may be continuous in time, for example, the indication value "01" corresponds to the beam 1 and the beam 2, the start time of the beam 1 is S2, the duration is T12, the start time of the beam 2 is the end time of the beam 1, and the duration of the beam 2 is T22.

When the number of beams corresponding to the beam indication index value is multiple, if the time information of the multiple beams is discontinuous in time, the second mapping relationship or the third mapping relationship may include a start time (or information for determining the start time) of each beam of the at least one beam corresponding to each indication value and a duration (or information for determining the duration) of each beam of the at least one beam. As an alternative example, an alternative form of the second mapping relationship is shown in Table 4-2.

TABLE 4-2

In this example, the number of beams corresponding to different beam indication index values may be one or multiple, and when the number of beams corresponds to multiple beams, the time information of the multiple beams may be discontinuous in time, for example, the indication value "01" corresponds to the beam 1 and the beam 2, the start time of the beam 1 is S12, the duration is T12, the start time of the beam 2 is S22, and the duration of the beam 2 is T22. The start time and duration of a beam may be jointly indicated by the Start and Length Indicator Values (SLIV), or may be separately indicated by the start indicator value (used to determine the start time of a beam) and the length indicator value (used to determine the duration of a beam).

Alternatively, each of the above beams may be limited to a time unit (e.g., a slot), e.g., only one beam for a time unit, and the SLIV indicates the beam start time and beam duration for a time unit. Alternatively, each of the above beams may not be limited to one time unit.

As an optional manner, the start time of the beam may also include 2 pieces of information, one piece of information is a start time unit of the beam, and the other piece of information is a start position of the beam in the start time unit, for example, beam indication information (a beam indication index value) is transmitted in a time unit n, the start time unit of the beam 1 indicated by the beam indication information is a time unit n + k, the start position of the beam 1 is a 3 rd OFDM symbol in the time unit n + k, optionally, the duration of the beam 1 is from the 3 rd OFDM symbol in the time unit n + k to a 10 th OFDM symbol in the time unit n + k (optionally, the beam indication information may indicate the duration of the beam when indicating the duration of the beam, such as 8 OFDM symbols in this example, or indicate the end position of the beam, such as the 10 th OFDM symbol in the time unit n + k in this example, or in another form, as long as information capable of determining the duration of the beam, the duration of the beam 1 may be a value of 3238, where the duration of the 3 rd OFDM symbol in the time unit n + k to the time unit n + k is an integer 3238, or another integer 3238, such as a non-integer 3238, where x, and z is an integer. By analogy, the start time and duration of beams 2, 3, etc. can be obtained in this way.

In addition to determining the time information of each first beam based on the first information (i.e., implementing the joint indication beam and the time information of the beam using the first information), the time information of each beam may be determined based on the acquired third information. The third information may be used to indicate time information of the at least one first beam, that is, information used to determine a start time and a duration of the at least one first beam, where the third information is appointment information or received information, or the obtaining the third information includes:

the method includes the steps of obtaining fourth information and fifth information, wherein the fourth information is used for determining the starting time of at least one first wave beam, the fifth information is used for determining the duration of the at least one first wave beam, the fourth information is appointed information or received information, and the fifth information is the appointed information or the received information.

That is, the start time and duration of the time of use of a beam may be determined jointly or independently (the joint or independent determination may also be applied to the alternatives for determining time information described above). For the independently determined manner, the start time and the duration of the first beam may be determined based on two independent fourth information and fifth information.

For the mode that the third information, the fourth information or the fifth information is the agreed information, the agreed information can be understood as protocol presetting, namely agreed rules, namely the determination rule of the use time of the beam is agreed in advance, and the enhancer can determine the use time of the beam according to the agreed rules. For example, the default information includes a default start time determination rule and a default duration, and the default duration is the duration of each of the at least one first beam, and the enhancer may determine the start time of each of the first beams according to the start time determination rule.

As for the optional manner in which the third information, the fourth information, or the fifth information is received, a specific manner of obtaining the third information, the fourth information, or the fifth information is not limited in this embodiment of the application. For example, the booster may obtain the information by receiving a higher layer signaling configuration, or may obtain the information by the booster receiving a media access layer signaling or a physical layer information (i.e., DCI). The third information, the fourth information, or the fifth information may be other information independent of the first information, or may be acquired simultaneously with the first information. For example, the first information may be information included in DCI, the DCI information may include the first information and third information, and the enhancer may determine the at least one first beam according to the first information and may determine time information of each first beam according to the third information.

It is to be understood that, when the first information is one of at least one first information included in the second information, the second information further includes third information corresponding to each first information, that is, the second information may include information corresponding to at least one second network device, where the information includes the first information and the third information, and the third information may be the first time indication information described in the foregoing or the second time indication information corresponding to the first network device. Of course, the third information may also be time indication information independent of the second information, such as the third time indication information or the fourth time indication information described above.

In an optional embodiment of the present application, the first information or the third information may include at least one of a first offset value and a first time, the first offset value being an offset value between a starting time of at least one of the at least one first beam and an acquisition time of the first information, the first time including a duration of the at least one first beam; the determining of the time information of the at least one first beam may include at least one of:

determining the starting time of at least one first wave beam according to the first deviation value and the acquisition time of the first information;

a duration of at least one first beam is determined based on the first time.

Optionally, the third information may be appointed information, at least one of the first offset value and the first time may be preset, for example, the first offset is appointed, the start time determining rule includes a first preset offset value, the offset value is a time offset between the start time of the beam and the acquisition time of the first information, and if the at least one first beam is one, the booster may determine the start time of the first beam according to the acquisition time of the first information and the offset value when acquiring the first information. For another example, the at least one first beam is 2 beams using time continuity, the offset value may be a time offset of a start time of a first beam of the 2 beams with respect to an acquisition time of the first information, and the enhancer may determine a start time of a second beam according to a duration of the first beam after determining the start time of the first beam according to the offset value. If the third information is the received information, the third information may be configured through higher layer signaling, medium access layer signaling, or physical layer signaling, and at least one of a start time and a duration of the at least one first beam is configured through the third information.

Optionally, when the first information is the first information corresponding to the current first network device determined from the second information, the obtaining time of the first information may refer to the obtaining time of the second information.

In an alternative embodiment of the present application, the time information of each of the at least one first beam is continuous in time;

the determining the usage time of the at least one first beam includes:

determining a start time of at least one of the at least one first beam and a duration of each first beam;

and obtaining the use time of each first beam according to the determined start time of at least one beam and the duration of each first beam, wherein the use time of one beam comprises the start time and the time sequence time of the beam.

As can be seen from the foregoing description, at least one beam corresponding to one booster may be continuous in use time or discontinuous in use time, and for the scheme that is continuous in use time, when determining the use time of at least one first beam, the information (e.g., the first information, the third information, etc.) for determining the use time may include the start time of one or more beams in the at least one first beam (or the information for determining the start time, such as the offset value described above), and the duration of each first beam (of course, if the durations of the respective first beams are the same, the duration of only one beam may be included), for example, the start time of the first beam and the duration of each first beam may be included, and since the use times of the respective first beams are continuous, the start time of the second first beam may be determined according to the start time and the duration of the first beam, and similarly, according to the start time and the duration of the second beam, the start time of the first beam may be determined, and so on the like.

It is understood that the above-mentioned various alternative embodiments provided in this application can be implemented independently, and different embodiments can also be implemented in combination without contradiction between the embodiments.

In an alternative embodiment of the present application, the method further comprises:

acquiring sixth information, wherein the sixth information is used for configuring at least one second beam used for transmitting information;

and determining at least one second beam according to the sixth information so as to transmit the information through each second beam.

Optionally, the at least one second beam comprises at least one first beam, i.e. the at least one first beam may be determined from the at least one second beam.

In this alternative, the second beam may be the beam from which the beam measurements are made. It can be understood that, for the booster, the booster is used for forwarding data and/or control information, the booster does not know what information the information to be transmitted is, and the booster only needs to know which beam can be used by the booster, that is, the booster can determine which second beam the booster can use to transmit information according to the received sixth information.

Based on this alternative, the booster may determine one or more second beams it may use by receiving the sixth information, and may transmit information to the UE using the second beams after receiving information (data and/or control information) that needs to be transmitted to the UE. Optionally, the UE may receive, from the base station, related information for instructing the UE to perform beam measurement on the second beam, perform beam measurement based on the received information, and feed back the measurement result to the base station, and the base station may determine, according to the beam measurement result fed back by the UE, which one or more second beams are used as the first beam, so as to meet a requirement of beam measurement, and improve transmission performance of a subsequent enhancer for transmitting information through the first beam.

The specific form of the content included in the sixth information is not limited in the embodiments of the present application, for example, the sixth information may include a beam indication value or a direct indication beam identifier, and the enhancer may determine which second beam or second beams are included according to the indication information, and perform information transmission through the determined second beams.

Wherein the at least one second beam is a transmission beam, that is, a beam used by the booster to transmit information to the UE. Optionally, the sixth information may further include information indicating that each second beam is a transmission beam or a reception beam.

Optionally, the obtaining the sixth information may include:

receiving a second signaling, wherein the second signaling carries sixth information;

wherein the second signaling comprises at least one of higher layer signaling, media access layer signaling, and physical layer signaling.

For the specific description of the second signaling, refer to the related description of the first signaling in the foregoing, and the description of the first signaling in the foregoing may also be applied to the second signaling when there is no case that the actual implementation is not logical.

In an optional embodiment of the present application, the at least one second beam may be used periodically, and the sixth information is further used to configure a usage period of the at least one second beam and time information of each second beam;

the determining, according to the sixth information, the at least one second beam to transmit information through each second beam includes:

determining at least one second beam, a use period of the at least one second beam and a use time of each second beam according to the sixth information;

and periodically transmitting information by using each second beam according to each second beam and the using time of the second beam.

That is, the sixth information may be used to indicate at least one second beam to the booster, and may also be used to configure time information of each second beam, and the booster may determine the use time of each second beam according to the time information of each second beam, and perform information transmission on the use time corresponding to each second beam. The at least one second beam may also be used periodically, the sixth information may also indicate a period duration of the period, that is, the usage period, and the enhancer may transmit information periodically at the usage time corresponding to each second beam according to the usage period. For example, the usage period is P, and the booster uses each second beam to perform information transmission every time period P.

The indication manner of the usage period and the indication manner of the usage time of each second beam are not limited in this embodiment, for example, the usage period may be actual duration information, e.g., 1 second, or may also be relative duration, e.g., the usage period may be indicated in a time unit manner, e.g., the usage period is a plurality of time units, and one time unit may be one time slot, one OFDM symbol, or one frame, etc. The time of use of each second beam may include, but is not limited to, the manner described above for implementing the indication of the time of use of the first beam, for example, the time information of one beam may be an offset value, the offset value may be a time offset corresponding to the start time of each period of the beam, the start time of the beam may be determined according to the start time of the period and the offset value in each period, and the duration of the beam may be an approximate value or may be a duration information indicated by the sixth information.

Optionally, the time information of each second beam of the at least one second beam may be continuous in time, and the information (which may be sixth information or other information independent of the sixth information) for determining the usage time of each second beam may include information indicating a start time of a first beam of the at least one second beam and information indicating a duration of each second beam, and if the durations of each second beam are the same, the information for determining the time information of each second beam may also include information configuring the start time and the duration of the first beam of the at least one second beam.

determining a time of use of the at least one first beam;

if there is an overlap time between the usage time of at least one first beam and the usage time of at least one second beam, the method may further include at least one of the following for the first beam and the second beam corresponding to the overlap time:

the first method is as follows: transmitting information based on the first beam and the use time of the first beam, and not transmitting information on the second beam in the current period;

the second method comprises the following steps: transmitting information based on at least one second beam and the using time of each second beam in the current period, and not transmitting information on the first beam;

the third method comprises the following steps: transmitting information based on at least one second beam and the using time of each second beam in the current period, and transmitting information based on the non-overlapping time of the first beam and the first beam, wherein the non-overlapping time is the time except the overlapping time in the using time of the first beam;

the method is as follows: and transmitting information based on the first beam and the using time of the first beam, and transmitting information based on at least one second beam and the using time of each second beam in the current period.

This aspect of the present application provides several alternative embodiments for situations where there may be overlap between the time information of the first beam and the time of use of the second beam. It is to be understood that the above-mentioned transmission of information based on the first beam and the time of use of the first beam means that data and/or control information is transmitted or received on the time of use of the first beam, and the transmission of information based on the second beam and the time of use of the second beam means that information is transmitted on the time of use of the second beam.

When at least one first beam configured by the first information is multiple, the transmission of information based on the first beam and the use time of the first beam described in the first to fourth modes refers to the first beam having an overlapping time with the second beam in use time.

Based on the first mode, when the first beam and the second beam are overlapped in time, the first beam is preferentially used, and the requirement of data and/or control information transmission can be better met. Based on the second mode, the second beam is preferentially used, so that the requirement of beam measurement can be better met. Based on the third mode, the requirement of data and/or control information transmission can be met as much as possible on the premise of avoiding the interference of the first beam information transmission and the second beam information transmission. Based on the fourth mode, the enhancer may not need to determine whether the time of using the first beam and the time of using the second beam overlap, and the information transmission between the two may be performed normally. Optionally, as for the fourth mode, if there is time overlap between at least one first beam and at least one second beam, the base station may control to implement that the time-overlapped first beam and second beam are the same beam, for example, the first beam a and the second beam b are the same beam, and within the use time of the beam, the information corresponding to the first beam and the information corresponding to the second beam may be transmitted simultaneously.

Optionally, if one or more beams b in one first beam a and at least one second beam have time overlap, in various optional manners of the scheme, the not transmitting information on the second beam may refer to not transmitting information on the second beam having time overlap with the beam a, or may refer to not transmitting information on all the second beams.

As another alternative, the base station may also indicate which of the above-described manners the booster is to take. For example, the booster may receive an indication indicating a target processing mode used by the booster, i.e., a processing mode when there is an overlap between the time information of the first beam and the time information of the second beam.

Optionally, the second beam may also be used aperiodically.

It should be noted that, in various alternatives provided in the present application, the base station may flexibly configure one or more of a transmit beam used by the booster for transmitting information, a receive beam used for receiving information, whether a beam is a transmit beam or a receive beam, and a usage time of each configured beam. The booster may determine one or more of a beam used for transmitting information, a beam used for receiving information, and time information of each beam according to the related information transmitted by the base station. The embodiment of the present application is not limited to a specific manner in which the base station implements the configuration, and the specific manner may be indicated in information sent by the base station to the booster, or a manner agreed by a protocol, or may be determined jointly according to information sent by the base station and information agreed by the protocol. The above-mentioned plurality of items of information may be indicated or determined individually for each item, or may be indicated or determined jointly.

In order to better understand and explain the scheme provided by the embodiments of the present application, the following describes the scheme of the present application in more detail with reference to several alternative embodiments. It should be noted that in the following examples, combinations of one or more of the alternative embodiments provided in the present application may be included. This combination should not be construed as limiting the application to the practice of the embodiments, and each alternative embodiment can be practiced alone or in combination with one or more other alternative embodiments.

In the embodiments provided by the present application, what the booster specifically has for information to be transmitted and/or received by itself may not be known, and by performing the scheme provided by the embodiments of the present application, the booster may determine which beam or beams it may use to transmit and/or receive information, and may also determine the time information of each beam.

The first embodiment is as follows:

an alternative to determining at least one first beam (which may also be referred to as a booster beam) for the booster is provided in this embodiment.

The booster may determine, by receiving the first signaling, a transmit beam for which the booster transmits information (data and/or control information) to the UE and/or a receive beam for which the booster receives information transmitted by the UE, the transmit beam and/or the receive beam being the first beam. The first signaling may be a higher layer signaling, a medium access layer signaling, or a physical layer signaling, that is, DCI, and in this embodiment, the physical layer signaling is taken as an example for description.

The DCI may be transmitted in a specific Search space (UE-specific Search) of the booster, and the transmit beam of one booster and/or the receive beam of the booster may be notified in one DCI using this method.

The booster beam indication channel (i.e. the channel transmitting the first signaling) carries DCI which may be specific to the UE, the booster may receive information of this DCI, and then the booster determines its own transmit and receive beams according to the information in the DCI. The beam indication information in the DCI may be L bits (L is a positive integer, and the value of L is preset by a protocol or configured by higher layer signaling, or determined by the number of beams B (i.e., the number of first beams) to be indicated, for example,

i.e., log2 (B) is rounded up to give L.

The DCI can also be transmitted in a common search space, and by adopting the method, the transmitting beam of more than one intensifier and/or the receiving beam of the intensifier can be informed in one DCI, so that the resources occupied by the DCI can be saved.

An optional beam (this beam can be the sending beam of the booster, can also be the receiving beam of the booster) indicates the method to: within one booster beam indication channel (i.e., DCI), there are M information blocks (i.e., the second information contains M first information, M is a positive integer, preset by the protocol, or configured by higher layer signaling, e.g., M equals 1), and each information block has L (L is a positive integer, the value of L is preset by the protocol, or configured by higher layer signaling, or determined by the number of beams B that need to be indicated) bits of information, each information block indicating for each booster beam.

In the example shown in fig. 7a, there are M information blocks (information block 1, information block 2, …, information block M, i.e., M first information) in the beam indication channel, the M information blocks correspond to M boosters one-to-one, the first information block (e.g., information block 1) of the M information blocks indicates the beam of booster 1, the second information block (e.g., information block 2) indicates the beam of booster 2, and so on, the mth information block (e.g., information block M) in the beam indication channel indicates the beam of booster M.

Wherein, the enhancer beam indication channel may be a group-common DCI, a group of enhancers may receive information of the DCI, and each enhancer determines its transmit and receive beams according to a corresponding information block in the DCI, such that the above-mentioned M enhancers are a group of enhancers. Wherein the mapping relationship between each information block indication information (i.e. the content of the information block) and each enhancer (an alternative to the first mapping relationship) may be obtained by a high layer signaling configuration, a system information indication, or by an implicit way.

For example, the above L is equal to 2, and the corresponding relationship between the beam indication information and the beam may be as shown in table 1 in the foregoing.

Example two

An alternative approach to determining the time information of at least one first beam corresponding to the booster is provided in this embodiment.

The above embodiments describe the method of indicating the booster beam, and optionally, the start-stop time (i.e., the time used) of the booster beam may also be determined, and one way to determine the start-stop time of the booster beam is to determine the start time (S) and the duration (T) of the beam. Several alternative implementations are provided in this example below.

In this embodiment, the indication manner of the first beam (i.e. the first signaling) is still described by taking the example of indicating the beam by the physical layer signaling, and it can be understood that the indication manner of the beam may be extended to applying the higher layer signaling or the medium access layer signaling indication.

In one mode

In this way, when the base station indicates the beam used by at least one booster (i.e. the second information includes at least one first information), a determination method of the corresponding use time of each booster is provided. Wherein, the beams and the use time of the beams may be indicated jointly (as in the schemes shown in fig. 7a to 7 c) or may be indicated independently (as in the scheme shown in fig. 7 d).

As an alternative, each of the second information may be used to configure both a beam used by each booster and a use time of the beam. Still taking fig. 7a as an example, the second information includes M information blocks, where the M information blocks correspond to M boosters one-to-one, a first information block (e.g., information block 1) of the M information blocks can be used to indicate a beam of booster 1 and a usage time of the beam, a second information block (e.g., information block 2) indicates a beam of booster 2 and a usage time of the beam, and so on, an mth information block (e.g., information block M) indicates a beam of booster M.

As another alternative, as shown in fig. 7b, the second information includes M pieces of first information and 1 piece of time indication information (i.e., first time indication information), where the M pieces of first information are respectively used to indicate beams that can be used by the M boosters, and the first time indication information is used to determine the use time of the beams of the M boosters.

As another alternative, as shown in fig. 7c, the second information includes M pieces of first information and M pieces of time indication information (i.e., second time indication information), where the M pieces of first information are respectively used for indicating beams that can be used by M boosters, and each piece of second time indication information is used for determining the use time of a beam of one booster. For example, the first information block (information block 1) is used to indicate the beam of the booster 1, the M +1 th information block (information block M + 1) is used to determine the usage time of the beam of the booster 1, the second information block (information block 2) is used to indicate the beam of the booster 2, the M +2 th information block (information block M + 2) is used to determine the usage time of the beam of the booster 2, and so on.

As another alternative, as shown in fig. 7d, the second information includes M first information, and one first information is used to configure the used beam of one booster. The boosters may also determine, by acquiring a time indication information independent of the second information, that is, the third time indication information in the foregoing, after each booster receives the second information, a corresponding beam according to the first information corresponding to the booster in the second information, and after obtaining the third time indication information, the booster may determine the use time of the beam according to the indication information.

As another alternative, as shown in fig. 7e, the second information includes M pieces of first information, and after acquiring the second information, the booster may determine the corresponding beam according to the first information corresponding to itself in the second information. The booster may further obtain time configuration information independent of the second information, where the time configuration information includes M fourth time indication information (e.g., time indication information 1, time indication information 2, …, and time indication information M shown in fig. 7 e), and after receiving the time configuration information, the booster may determine fourth time indication information corresponding to the booster from the M fourth time configuration information, and determine the use time of the beam used by the booster according to the determined indication information.

As still another alternative, the usage time of the beams corresponding to the M boosters may be determined according to the rules agreed by the protocol. For example, the using time of the beams corresponding to the M boosters may be the same, the starting time of the beam agreed by the protocol is the acquiring time of the second information plus the agreed time offset value, and the duration of the beam is an agreed duration.

The second method comprises the following steps:

the start time (S) and duration (T) of use of the indicated beam may be determined independently of the indicated beam.

Alternatively, the start time (S) of the beam usage may be determined by an offset value (i.e. the first offset value) between the PDCCH indicated by the booster beam (i.e. the above-mentioned DCI acquisition time, which may be understood as time domain resource information for transmitting DCI, such as in which slot or OFDM symbol). The offset value may be in units of OFDM symbols or time slots, and may be preset by a protocol, or may be determined by the higher layer signaling configuration received by the booster, or may be determined by the medium access layer signaling received by the booster, or may be determined by the physical layer signaling.

The duration (T) of the beam may also be in units of OFDM symbols or time slots, and may be preset by a protocol, determined by the booster receiving a high layer signaling configuration, determined by the booster receiving a medium access layer signaling, or determined by a physical layer signaling.

In one example shown in fig. 8, assuming that DCI for indicating a first beam is transmitted in the nth OFDM symbol (acquisition time) of one slot, that is, a PDCCH for transmitting booster beam indication information (PDCCH indicated by the booster beam shown in the figure) is transmitted in the nth OFDM symbol, and the offset value is m OFDM symbols, the starting time (S) of the first beam is the (n + m) th OFDM symbol, and the timing time of the beam may be preset or determined by information carried in signaling.

Optionally, the start time (S) and the duration (T) of the beam usage may be jointly indicated, for example, as shown in table 2 in the foregoing, one beam time indication index value (i.e., the second indication value) corresponds to one start time (S) and one duration (T), and the enhancer determines the start time and the duration of the first beam according to the obtained second indication value. The method can save the indicated information bit number. In practical implementation, the starting time (S) may be a specific time, or may be the offset value used for determining the starting time.

Mode III

The start time (S) and duration (T) of use of the indicated beam are determined jointly with the indicated beam.

One indication method may be to indicate a beam and a start time (S) and duration (T) of beam use, respectively, for different fields in one DCI, e.g., field a includes L1 bits for indicating a beam and field B includes L2 bits for indicating a start time (S) and duration (T) of beam use. By adopting the method, the starting and stopping time of the beam with the indication beam can be indicated by one DCI, so that resources occupied by the PDCCH can be saved.

Another indication method may indicate M beams (i.e., at least one first beam is 2 first beams) and a start time and duration used by each beam for a field in one DCI. For example, as shown in fig. 9, M equals 2,2 beams (the first and second beams shown in the figure) are used in tandem, the duration of the first and second beams are T1 and T2, respectively, and the end time of the first beam is the start time of the second beam. The DCI field may include indication information of a start time S of the first beam (e.g., an offset value corresponding to the start time of the first beam), a duration T1 of the first beam, and a duration T2 of the second beam, and the enhancer may determine the start time S of the first beam according to the indication information of the start piece of the first beam, and determine the start time of the second beam according to the start time S of the first beam and the duration T1.

Another optional indication method may be: a beam indication index value, the number of beams (optional), the respective beams and the start time and duration of each beam are determined (alternative of the first mapping), and then the enhancer indicates the number of acquired beams, the respective first beams and the start time and duration of each beam by receiving the index value (i.e. the first indication value), as in the example shown in table 4-1 above.

Another optional indication method may be: a beam indication index value, the number of beams (optional items), the respective beams, and the start time and duration correspondence of each beam (alternative items of the first mapping relation) are determined, and then the booster indicates the number of acquired beams, the respective first beams, and the start time and duration of each beam by receiving the index value (i.e., the first indication value), as in the example shown in table 4-2 above.

EXAMPLE III

In this embodiment, the booster may determine, by receiving the second signaling (the signaling including the sixth information) sent by the base station, the transmission beam for the booster to send information to the UE and/or the reception beam for the booster to receive information sent by the UE.

The second signaling may be a higher layer signaling, a medium access layer signaling or a physical layer signaling.

The beams indicated by the second signaling may be used periodically, and optionally, the number of beams in each period may be the same, the start-stop time of each beam may be the same, and the beams at the same time position are the same. For example, the period of the beam is P, S beams (i.e., S second beams) are transmitted in each period P, S beams may be continuously transmitted, the total duration of the S beams is T, and the duration of each beam of the S beams may be T1, T2, …, TS, respectively. Of course, the S beams may also be discontinuous, and the start time and duration of each beam may be indicated by the second signaling.

In one example shown in fig. 10, S is 4, that is, the number of the at least one second beam is 4, which are respectively the first beam to the fourth beam shown in the figure, and the use time of the 4 beams is continuous, optionally, the second signaling may include indication information of the 4 beams, indication information of the start time of the first beam in the 4 beams, and respective durations of the 4 beams, and if the durations of the 4 beams are the same, the second signaling may also include indication information of the start time of the first beam and a total duration of the 4 beams. The booster can determine which 4 beams are specifically 4 beams and the time information of each beam according to the second signaling, and send out the information corresponding to each beam in the using time of the beam through each beam.

The advantage of using this method is that it can provide measurement signals (configuration information) for the UE to measure the transmission performance of each beam, and then feed back the measurement result to the base station, and the measurement result can be used as the basis for the base station to determine the beam of the booster.

Example four

In this embodiment, a method for processing inconsistency between a beam determined by first signaling and a beam determined by second signaling is provided, that is, a processing mode when the beam determined by the first signaling and the beam determined by the second signaling overlap in time is provided.

When the beam indicated by the first signaling (i.e. the first beam) and the beam indicated by the second signaling (i.e. the second beam) overlap in time, as shown in an example in fig. 11, the second signaling indicates 4 second beams, the 4 beams are used periodically, the first signaling indicates a first beam, the starting time of the beam is S, the duration of the beam is T, and as shown in the figure, the using time of the first beam (i.e. the time from S to S + T) overlaps with the using time of the 4 second beams in one period P (the overlapping time is the overlapping range between two dotted lines shown in fig. 11). For this case, several alternative processing methods are provided in this embodiment.

One alternative method is: the method has the advantages that the protocol is simple, the method can be controlled and realized by the base station, and even if the time is overlapped, the enhancer can also send the data and/or control signaling corresponding to the first beam and send the information corresponding to the second beam.

Another alternative is: the beam of the first signaling indication and the beam of the second signaling indication are not constrained to be the same in the temporally overlapping portions. In this alternative method, if there is an overlapping portion between the beam indicated by the first signaling and the beam indicated by the second signaling in time, and the beam indicated by the first signaling and the beam indicated by the second signaling corresponding to the overlapping portion are different, it may be determined that the beam indicated by one of the beam indicated by the first signaling and the beam indicated by the second signaling is used as the beam used by the booster, that is, the booster may transmit corresponding information only using the beam indicated by the first signaling.

If the beam indicated by the first signaling is different from the beam indicated by the second signaling in the time overlapping portion of the beam indicated by the first signaling and the beam indicated by the second signaling, an optional processing manner is as follows: the advantage of determining the beam indicated by the first signalling as the beam used by the booster, i.e. the booster does not use the beam indicated by the second signalling, is that the beam requirements for data and/or control information transmission can be met preferentially. Another optional processing mode is as follows: the advantage of determining the beam indicated by the second signalling as the beam used by the booster is that the beam requirements for beam measurements can be met preferentially.

EXAMPLE five

In this embodiment, a scheme is provided that can jointly indicate a booster receive beam and a booster transmit beam, i.e., at least one first beam includes at least one transmit beam used by a booster to transmit information (data and/or control information) to a UE and at least one receive beam used by the booster to receive information transmitted by the UE.

The method can be adopted when the relative position of the UE and the intensifier is fixed, and the judgment mode of the relative fixed position is not limited in the embodiment of the application, optionally, the base station can determine the UE and the intensifier which meet the relative fixed condition according to a preset judgment strategy. For UEs and boosters that satisfy the above-mentioned relative position fixing, the booster receive beam and the booster transmit beam may be associated, and thus, the booster receive beam and the booster transmit beam may be jointly indicated. The method has the advantages that the beam indication information can be saved, and the relative position relationship between the UE and the intensifier is stable, so that the performances of the intensifier transmitting beam and the intensifier receiving beam indicated by adopting a joint indication mode are not obviously reduced, and the use perception of a user is not influenced.

In practical implementation, if the correlation between the transmission beam and the reception beam is poor (the relative position relationship between the UE and the booster fluctuates greatly), the booster reception beam and the booster transmission beam may be indicated independently, that is, the beam for transmitting information and the beam for receiving information may be indicated separately, for example, it may be determined through a high-layer signaling configuration whether to indicate the booster reception beam and the booster transmission beam independently or indicate the booster reception beam and the booster transmission beam jointly, so that an appropriate indication method may be selected according to the degree of correlation between the booster reception beam and the booster transmission beam.

As an example, an alternative form of jointly indicating booster receive beams and booster transmit beams is shown in table 5, where one beam indication index value (i.e., a first indication value) corresponds to one receive beam and one transmit beam, and the booster receives data and control signaling (i.e., control information) using the indicated receive beam for the duration of the beam, as shown in table 5; if the booster transmits data and control signaling, the indicated transmit beam is used for transmission. For example, if the indicated value carried in the first information is "00", the booster may receive data and/or control signaling sent by the UE during the use time of the beam J1, and may send data and/or control signaling to the UE during the use time of the beam F1.

Table 5: beam indication index value and corresponding relation of transmitting beam and receiving beam

Beam indication index value	Transmitting beam	Receive beam
			00	F1	J1
01	F2	J2
			10	F3	J3
11	F4	J4

Optionally, the usage time of the jointly indicated transmit beam and receive beam may be continuous in time, as shown in fig. 12, the beam indication index value indicated in the first information is "01", the indicated beam start time is S, and the beam duration is T, the transmit beam of the booster may be determined as F2, the receive beam is J2, and the transmit beam F2 is a beam used earlier according to the index value "01" and the above correspondence, optionally, if the durations of the receive beam and the transmit beam are the same, the start time and the duration of the two beams may be determined respectively according to the start time S and the total time T, if the durations of the receive beam and the transmit beam are the same, the start time of the receive beam may be determined according to the duration T1 of the transmit beam, and the indication of the duration T1 of the transmit beam may be determined in the first information or in other optional manners. During time T1 within the beam duration T, the booster transmits data and/or control signaling using the transmit beam F2, and during time T2 within the beam duration T, the booster receives data and/or control signaling using the receive beam J2.

By adopting the scheme provided by the embodiment of the application, the performance of information transmission (including sending and receiving) in the communication system can be effectively improved.
