Description

Technical Field

[0001] The present invention relates to the technical field of communications.

Background Art

[0002] Compared with the conventional 2G, 3G, and 4G systems, the 5G system can provide a larger bandwidth and a higher data rate, and can support more types of terminals and vertical services. Therefore, the frequency band range / working bandwidth supported by the 5G system is clearly larger than that of the 2G, 3G, and 4G systems, and the 5G system can support a higher carrier frequency. For example, the 5G system can be deployed in the millimeter wave band.

[0003] However, the higher the carrier frequency, the more serious the fading encountered by the signal in the transmission process. Therefore, in the actual deployment of the 5G system, especially in the millimeter wave band, the problem of how to better enhance cell coverage remains to be solved.

[0004] Note that the introduction of the above background art is for clearly and completely explaining the technical solution of the present invention and for facilitating the understanding of those skilled in the art. These technical solutions should not be construed as well-known to those skilled in the art just because they are described in the background art of the present invention.

Summary of the Invention

Problems to be Solved by the Invention

[0005] To better address the coverage issues of cellular mobile communication systems in actual deployments, employing RF repeaters to amplify and forward signals between devices is a commonly used deployment method. RF repeaters are widely applied in actual deployments of 2G, 3G, and 4G systems, and their advantages include low cost, ease of deployment, and the avoidance of excessive latency. Generally speaking, a conventional RF repeater is a device that amplifies and forwards the round-trip signals of devices in the RF domain. In other words, a conventional RF repeater is a non-regenerative relay node, and it simply amplifies and forwards all received signals directly.

[0006] The RF repeater proposed in the Rel-17 3GPP(registered trademark) research can enhance the network coverage of 5G systems by forwarding transmissions between base stations and terminals. However, because the RF repeater is transparent to both base stations and terminals and is not controlled by the base station, the RF repeater in Rel-17 interferes with other equipment, its energy consumption cannot be controlled, and it must constantly be in a state of monitoring transmissions.

[0007] The Rel-18 study proposed that a network-controlled repeater (NCR) can receive side control information. The NCR includes an NCR-MT (also called a communication unit) and an NCR-Fwd (also called a forwarding unit). Of these, the NCR-MT can communicate with a base station and control the forwarding of the NCR-Fwd based on the control information transmitted by the base station. The NCR-Fwd constitutes the part of the NCR that realizes forwarding between the base station and the terminal, and includes a backhaul link (BH-link) for the NCR to connect to the base station and an access link (AC-link) on the terminal side.

[0008] To improve NCR coverage, ensure more accurate transmission of communications between base stations and terminals, and reduce interference with other surrounding equipment, base stations control and direct the NCR-Fwd backhaul link beam and access link beam. Currently, only the use of beam identifiers (beam indexes) for access link beam management has been determined.

[0009] The inventors discovered the following: In the prior art, there is no concrete plan for how to determine the beam identifier and how to use the beam identifier to manage the access link beam; in other words, there is no effective access link beam management mechanism, so the NCR access link beam cannot be determined, and the beam identifier cannot be effectively utilized to complete the transmission between the terminal and the base station.

[0010] To solve one or more of the above-mentioned problems, embodiments of the present invention provide a method and apparatus for transferring a transceiver access link (transceiver access link). That is, embodiments of the present invention provide a corresponding solution to one or more of the above-mentioned problems. [Means for solving the problem]

[0040] In embodiments of the present invention, the transponder may be referred to as a network-controlled repeater (NCR). However, it may have other names, and different names for the transponder do not limit the embodiments of the present invention.

[0044] In the embodiment of the present invention, there is a beam correspondence between the uplink beam and the downlink beam, that is, the uplink beam and the downlink beam are common to each other.

[0045] The following examples illustrate the scenarios and problems associated with embodiments of the present invention, but the embodiments of the present invention are not limited thereto.

[0046] Figure 1 shows a communication system in an embodiment of the present invention. As shown in Figure 1, the communication system 100 may include network equipment 101, terminal equipment 102, and a transceiver 103.

[0047] In embodiments of the present invention, conventional operations (traffic / services) or future operational operations may be performed between the network device 101 and the terminal device 102. For example, these operations may include, but are not limited to, eMBB (enhanced Mobile Broadband), mMTC (massive Machine Type Communication), URLLC (Ultra-Reliable and Low-Latency Communication), etc.

[0048] As shown in Figure 1, the transceiver 103 receives a first RF signal from the network device 101, amplifies the first RF signal to obtain a first transfer signal, and / or transmits it to the terminal device 102, and / or receives a second RF signal from the terminal device 102, amplifies the second RF signal to obtain a second transfer signal, and transmits it to the network device 101.

[0049] Furthermore, as shown in Figure 1, communication may also be performed between the transceiver 103 and the network device 101 via communication links (Down C-link, Down Communication-link) and / or uplink communication links (Up C-link, Up Communication-link).

[0050] Figure 2 is a logic diagram of a transceiver in an embodiment of the present invention. As shown in Figure 2, the transceiver 103 includes an NCR-MT (also called a communication unit) and an NCR-Fwd (also called a transceiver unit), of which the NCR-MT communicates with the network device 101 and can control the transceiver of the NCR-Fwd based on control information transmitted by the network device 101. For example, the NCR-MT includes a receiving unit and a transmitting unit, the receiving unit receives control information from the network device 101, and the transmitting unit transmits relevant information to the network device 101. The NCR-Fwd is the part that realizes the transceiver between the network device 101 and the terminal device 102. The transceiver 103 includes a backhaul link (BH-link) for connecting to the network device 101 and an access link (AC-link) for connecting to the terminal device 102.

[0051] The following describes various embodiments of the present invention in conjunction with the drawings. These embodiments are merely illustrative and do not limit the present invention. [Examples]

[0052] An embodiment of the present invention provides a method for transferring a transceiver access link, which is applied to a transceiver, for example, to transceiver 103 in Figures 1 and 2.

[0053] Figure 3 shows a transfer method for a transceiver access link according to Embodiment 1 of the present invention. As shown in Figure 3, the method includes the following, namely, Step 301: The receiving unit of the transceiver receives the beam identifier of the access link from the network device; and Step 302: The transfer unit of the transferr performs a transfer using the beam corresponding to the received beam identifier.

[0054] In this way, the transceiver performs the transfer on the access link using the beam corresponding to the beam identifier received from the network device, enabling the network device to schedule the access link beam for the transceiver's transfer and enabling the transceiver to determine the access link beam for the transfer. Therefore, the beam identifier can be effectively used to complete the transfer between the terminal and the network device.

[0055] In some embodiments, the transceiver is a network-controlled transceiver, i.e., an NCR.

[0056] In some embodiments, the receiving unit of the transceiver is NCR-MT or a part of NCR-MT, and the transceiver's forwarding unit is NCR-Fwd. For example, see the relevant configuration in Figure 2.

[0057] In some embodiments, beam identifiers (beam indexes) are obtained by numbering the beams of the access link (AC-link), and network equipment indicates the beam identifier to be used by the transceiver.

[0058] Furthermore, beam identifiers may also be expressed as beam indexes, beam numbers, or beam sequence numbers.

[0059] Figure 4 shows a beam identifier according to Embodiment 1 of the present invention. As shown in Figure 4, the beams of the transporter access link are numbered, and the beam identifier includes beam #1, beam #2, and beam #3. The beam identifier may also be represented in other formats, and the present invention does not limit the display format of the beam identifier.

[0060] In some embodiments, the beam identifier received by the transporter is indicated by at least one of RRC signaling, MAC CE, and physical layer signaling.

[0061] The physical layer signaling may be, for example, DCI or other physical layer signaling.

[0062] In this way, by indicating the beam identifier of the access link through physical layer signaling, the signaling overhead and transmission delay associated with indicating the beam identifier can be reduced, thereby improving the utilization efficiency of the system.

[0063] In some embodiments, the beam identifier received by the transceiver is at least one of the beam identifiers of the access link configured by the network equipment, that is, the network equipment determines the beam identifier of the access link and instructs the transceiver to use at least one of the determined beam identifiers.

[0064] For example, suppose the beam identifiers of an access link set by a network device are beam #1, beam #2, beam #3, ... and when a transponder needs to perform a transfer over the access link, the beam identifier that the network device instructs the transponder to use (i.e., the beam identifier received by the transponder) is at least one of beams #1, beam #2, beam #3, ... set by the network device, and the transponder uses the beam corresponding to the received beam identifier to perform the transfer over the access link. The correspondence between the beam identifier set by the network device and the beam is determined by the implementation of the transponder.

[0065] In some embodiments, or the beam identifier received by the transceiver is at least one of the beam identifiers of the access link reported by the transceiver, that is, the transceiver determines and reports the beam identifier of the access link, and the network equipment instructs the transceiver to at least one of the beam identifiers reported by the transceiver.

[0066] For example, suppose a transponder reports beam identifiers beam #1, beam #2, beam #3, ... to a network device, and when the transponder needs to perform a transfer over an access link, the beam identifier that the network device instructs the transponder to use (i.e., the beam identifier received by the transponder) is at least one of beams #1, beam #2, beam #3, ... reported by the transponder, and the transponder uses the beam corresponding to the received beam identifier to perform the transfer over the access link, and the correspondence between the beam identifier instructed by the network device and the beam is determined by the implementation of the transponder.

[0067] If the beam identifier received by the transceiver is at least one of the beam identifiers of an access link set by a network device, for example, the beam identifier is set by the network device based on information reported by the transceiver.

[0068] In some embodiments, the information reported by the transceiver includes at least one of the following: beam quantity information supported by the access link, the relationships between beams of the access link, and whether it supports simultaneous transceiver on different beams of the access link.

[0069] In some embodiments, the beam quantity information supported by the access link includes at least one of the following: the total number of beams supported by the access link, the total number of forwarded beams supported by the access link, the total number of beams for simultaneous forwarding supported by the access link, and the number of beams of different types.

[0070] In some embodiments, different types of beams are beams of different directions, beams of different widths, or beams of different precision (resolution).

[0071] The relationships between beams, as well as the direction and width of the beams, will be explained in detail below.

[0072] In some embodiments, supporting simultaneous transmission on different beams of the access link includes at least one of the following: supporting the number of beams for simultaneous transmission, supporting the beam accuracies of the simultaneous transmissions being the same or different, and supporting the relationship between the beams for simultaneous transmissions.

[0073] In the above example, if the beam identifier received by the transceiver is at least one of the access link beam identifiers set by the network equipment, the network equipment sets the access link beam identifier based on the information reported by the transceiver. Alternatively, for example, the access link beam identifier may be set by the network equipment, meaning the network equipment independently determines the access link beam identifier without requiring the transceiver to report the information.

[0074] If the beam identifier received by the transceiver is at least one of the beam identifiers of an access link configured by the network equipment, the method may further include the transceiver receiving inter-beam relationship information corresponding to the beam identifier from the network equipment. That is, the network equipment further instructs the transceiver on inter-beam relationship information corresponding to the beam identifier of an access link.

[0075] If the beam identifier received by the transceiver is at least one of the beam identifiers of the access link reported by the transceiver, the method may further include the transceiver reporting to the network equipment beam-to-beam relationship information corresponding to the beam identifier.

[0076] In some embodiments, network equipment provides instructions based on the beam identifier of the access link reported by the transceiver, meaning that the network equipment does not need to process the beam identifier of the access link.

[0077] Alternatively, network equipment processes the beam identifiers of the access links reported by the transporter and then instructs the transporter on the beam identifiers. For example, network equipment renumbers the beam identifiers of the access links reported by the transporter based on a single reference value, for example, assigning 0, 1, 2, 3 to beam #4 reported by the transporter.

[0078] The relationship between the beams will be explained in detail below.

[0079] In some embodiments, the relationship between beams may be referred to as a QCL (Quasi-Colocation) relationship between beams or a spatial relation between beams.

[0080] In some embodiments, the relationship between the beams corresponds to the relationship between beams with different beam identifiers.

[0081] For example, the relationship between the beams includes at least the case that beams corresponding to different beam identifiers have different directions, or beams corresponding to different beam identifiers have the same direction but different widths.

[0082] In some embodiments, the beam width may be expressed as the beam precision (resolution) or beam type.

[0083] Figure 5 is a diagram showing the relationships between beams according to Embodiment 1 of the present invention. As shown in Figure 5, the beam corresponding to beam identifier beam #1 is a beam in the same direction as the beams corresponding to beams #4, #5, and #6, the beam corresponding to beam #2 is a beam in the same direction as the beams corresponding to beams #7, #8, and #9, and the beam corresponding to beam #3 is a beam in the same direction as the beams corresponding to beams #10, #11, and #12.

[0084] Furthermore, the beams corresponding to beam identifier beam #1, beam #2, and beam #3 are beams in different directions; the beams corresponding to beam #4, beam #5, and beam #6 are beams in different directions; the beams corresponding to beam #7, beam #8, and beam #9 are beams in different directions; and the beams corresponding to beam #10, beam #11, and beam #12 are beams in different directions.

[0085] In some embodiments, the relationships between beams may include Type 1 and Type 2, of which Type 1 refers to two beams having different directions, for example, the beam corresponding to beam #1 and beam #2 in Figure 5, the beam corresponding to beam #4 and beam #3, the beam corresponding to beam #5 and beam #8, the beam corresponding to beam #11 and beam #12; and Type 2 refers to two beams having the same direction but different widths (different accuracies or types), for example, the beam corresponding to beam #1 and beam #4 in Figure 5, the beam corresponding to beam #2 and beam #9.

[0086] As described above, in some embodiments, network equipment may determine the relationships between beams of an access link, that is, the relationships between beams corresponding to different beam identifiers, and instruct the transceiver accordingly.

[0087] For example, a network device uses a single bit to indicate whether the relationship between beams #1 and #2 is of type 1 or type 2. For instance, if the bit indicates "0", it means that beams #1 and #2 have a type 1 relationship, and if the bit indicates "1", it means that beams #1 and #2 have a type 2 relationship.

[0088] Furthermore, for example, network equipment indicates that beams corresponding to beam identifiers in the same set have the same direction but different widths (different precisions or types), for example, set 1 is {beam #1, beam #4, beam #5, beam #6} and set 2 is {beam #2, beam #7, beam #8}.

[0089] Furthermore, for example, network equipment can identify beams in a set that have the same width (or precision or type), such that set 1 is {beam #1, beam #2, beam #3} and set 2 is {beam #5, beam #6, beam #7}.

[0090] As mentioned above, in some embodiments, the transponder may determine the relationships between beams of the access link, i.e., the relationships between beams corresponding to different beam identifiers, and report this to the network equipment.

[0091] For example, the transporter uses one bit to report whether the relationship between the beam corresponding to beam #1 and the beam corresponding to beam #2 is type 1 or type 2. For instance, if the bit indicates "0", it means that the beam corresponding to beam #1 and the beam corresponding to beam #2 have a type 1 relationship, and if the bit indicates "1", it means that the beam corresponding to beam #1 and the beam corresponding to beam #2 have a type 2 relationship.

[0092] Additionally, for example, the transporter reports beam identifiers, and the beams corresponding to the same beam identifier in the same set are beams of different widths (different precisions or types) in the same direction, for example, set 1 is {beam #1, beam #4, beam #5, beam #6}, and set 2 is {beam #2, beam #7, beam #8}.

[0093] Additionally, for example, the transporter reports beams in a set that have the same width (or precision or type), such that set 1 is {beam #1, beam #2, beam #3} and set 2 is {beam #5, beam #6, beam #7}.

[0094] In some embodiments, the transporter may support one of the reporting methods described above, or it may support multiple reporting methods described above simultaneously.

[0095] Furthermore, in some embodiments, the relationships between beams corresponding to different beam identifiers may be defined by default.

[0096] For example, the beam relationship corresponding to the beam identifier is defined as either type 1 or type 2.

[0097] Furthermore, for example, it can be defined that beams corresponding to several beam identifiers are beams of different widths (different accuracies or types) in the same direction.

[0098] Furthermore, for example, it can be defined that beams corresponding to several beam identifiers are beams of the same width (same precision or type) but in different directions.

[0099] As mentioned above, the beam identifier of the access link received by the transceiver is set by the network equipment or reported by the transceiver.

[0100] Furthermore, in some embodiments, the beam information for the transceiver access link is defined by default.

[0101] For example, the number of access link beams supported by the transceiver is specified by default to be a maximum of M, e.g., 8 or 4.

[0102] Furthermore, for example, it can be specified by default that the transponder will perform transfers on M' access link beams simultaneously.

[0103] Additionally, for example, the relationships between beams in a transceiver access link are defined by default.

[0104] In some embodiments, the beam identifier received by the transporter indicates the corresponding beam identifier by a first number of bits.

[0105] For example, the first quantity is determined by the total number of beam identifiers of the access link, or by the total number of transmitted beams supported by the access link, or by the total number of beam identifiers received by the transmitter. For example, a beam identifier indicates the corresponding identifier digit by log2M bits, where M is the first quantity.

[0106] In some embodiments, or the beam identifier received by the transporter, indicates the corresponding beam identifier in a bitmap format.

[0107] For example, the number of bits in the bitmap is the total number of beam identifiers of the access link, or the total number of transmitted beams supported by the access link, or the total number of beam identifiers received by the transmitter.

[0108] In some embodiments, the network equipment indicates that the beam identifier may employ multiple methods.

[0109] For example, Method 1: The beam identifier received by the transceiver (i.e., the beam identifier indicated by the network equipment) is at least one of the beam identifiers of the access link reported by the transceiver, or the beam identifier received by the transceiver is at least one of the beam identifiers of the access link configured by the network equipment.

[0110] In other words, the beam identifier received by the transceiver is at least one (all or part) of the beam identifiers of the access link reported by the transceiver, or the beam identifier received by the transceiver is at least one (all or part) of the beam identifiers of the access link set by the network equipment.

[0111] For example, Method 2: The network device sets at least one beam identifier from among the beam identifiers of the access link set by the network device or at least one beam identifier from among the beam identifiers of the access link reported by the transceiver by RRC signaling, that is, when the network device sets the beam identifier of the access link, the RRC signaling sets at least one beam identifier from among the beam identifiers of the access link set by the network device, and when the transceiver reports the beam identifier of the access link, the RRC signaling sets at least one beam identifier from among the beam identifiers of the access link reported by the transceiver, and the MAC CE activates the first part of the beam identifier and the physical layer signaling field indicates the second part of the beam identifier, the first part of the beam identifier includes at least one beam identifier from among the beam identifiers set by the RRC signaling, the second part of the beam identifier includes at least one beam identifier from among the beam identifiers of the first part, and the beam identifier received by the transceiver is the second part of the beam identifier. Among these, physical layer signaling is, for example, DCI.

[0112] The following will provide an explanation through specific examples.

[0113] A transporter is assigned up to M1 beam identifiers via RRC signaling, and these M1 beam identifiers are used by the access link to transfer transmissions to terminal equipment within a specified serving cell. For example, M1 is determined by the transporter's ability to support the beam quantity of the access link, and M1 is a positive integer, e.g., 128. Each beam identifier corresponds to a beam in the transporter access link, and this correspondence is determined by the transporter's implementation.

[0114] For example, in order for a transceiver to forward downlink and uplink transmissions between terminal equipment and network equipment, the transceiver is configured with a list of up to 128 beam identifiers, which are configured in RRC signaling.

[0115] The transceiver receives activation instructions in MAC CE for mapping up to M2 beam identifiers, each beam identifier corresponding to a beam for uplink or downlink transceiver of the transceiver access link, where M2 is a positive integer and M1 is less than or equal to M1.

[0116] Figure 6 shows a MAC CE according to Embodiment 1 of the present invention. Note that the MAC CE shown in Figure 6 is merely an example, and the MAC CE in the embodiments of the present invention may employ various other structures.

[0117] For example, if a beam identifier is set in RRC signaling, the region T in MAC CE i This indicates the activation or deactivation status of beam identifier i (beam #i), and if not, the region T in MAC CE. i This is ignored. As shown in Figure 6, region T i When set to 1, it indicates that the beam identifier i (beam #i) is activated and mapped to a codeword in DCI that indicates the forward beam identifier of the access link, and area T i When set to 0, this indicates that the beam identifier i (beam #i) is deactivated and will not be mapped to a codeword in DCI that indicates the forward beam identifier of the access link.

[0118] When an activation command is mapped to a codeword in DCI, the transporter uses the beam identifier indicated by the DCI codeword to forward the downlink and uplink transmissions between the terminal equipment and the network equipment. The codeword for mapping beam identifiers in DCI is T i The order in which the values ​​are set to 1 (ascending order) determines the first T that is set to 1.i This maps to the codeword 0 in DCI, and the second T is set to 1. i This is mapped to a codeword of 1 in DCI, and the others can be inferred based on this. The number of beam identifiers to be activated is at most M2. The codeword for mapping beam identifiers in DCI indicates at most N beam identifiers, and there are Nlog2M2 codewords that indicate beam identifier ranges in DCI, where N is a positive integer and N is less than or equal to M2.

[0119] For example, the maximum number of beam identifiers that can be activated is 8. In this case, if DCI indicates that a beam identifier is invalid, the codeword in DCI is 0 bits; otherwise, it indicates that one beam identifier is 3 bits.

[0120] Furthermore, for example, in MAC CE, areas T4, T20, and T22 are activated. In this case, indicating 0 in DCI represents beam #4, indicating 1 represents beam #20, and indicating 2 represents beam #22.

[0121] Furthermore, for example, DCI indicates that the beam identifier codeword refers to two beam identifiers. In this case, the codeword in DCI consists of six bits.

[0122] In some embodiments, the beam identifier received by the transceiver includes a first beam identifier indicated by the network equipment, set by the network equipment, or reported by the transceiver, and a second beam identifier set by the network equipment using RRC signaling, activated by MAC CE, and indicated by the physical layer signaling domain. In other words, the beam identifier received by the transceiver is the first beam identifier and the second beam identifier indicated by the network equipment according to the above-described methods 1 and 2.

[0123] In some embodiments, based on the type of signal being transmitted, network equipment can determine, according to Method 1 or Method 2 described above, that the beam transmitting the signal corresponds to a first beam identifier or a second beam identifier.

[0124] For example, the beam on which the transceiver transmits broadcast signals corresponds to a first beam identifier specified by the network equipment according to method 1 described above, and the beam on which the transceiver transmits terminal-specific signals corresponds to a second beam identifier specified by the network equipment according to method 2 described above.

[0125] In some embodiments, the network equipment may further decide, based on whether the received beam configuration is a semi-static or dynamic beam configuration, to indicate, according to Method 1 or Method 2 described above, that the beam receiving the beam configuration corresponds to a first beam identifier or a second beam identifier.

[0126] For example, the beam from which the transceiver receives a semi-static beam setting corresponds to a first beam identifier specified by the network equipment according to method 1 described above, and the beam from which the transceiver receives a dynamic beam setting corresponds to a second beam identifier specified by the network equipment according to method 2 described above.

[0127] In some embodiments, the network equipment may further decide, based on the beam width, type, or precision of the access link beam, to designate a first beam identifier corresponding to the beam according to Method 1 described above, or to designate a second beam identifier corresponding to the beam according to Method 2.

[0128] For example, the broad beam of the transceiver access link corresponds to the first beam identifier indicated by the network equipment according to Method 1 described above, and the narrow beam of the transceiver access link corresponds to the second beam identifier indicated by the network equipment according to Method 2 described above. In other words, the low-precision beam of the transceiver access link corresponds to the first beam identifier indicated by the network equipment according to Method 1 described above, and the high-precision beam of the transceiver access link corresponds to the second beam identifier indicated by the network equipment according to Method 2 described above.

[0129] As can be seen from the above embodiment, the transceiver performs the transfer on the access link using the beam corresponding to the beam identifier of the access link received from the network device, thereby enabling the network device to schedule the access link beam for the transceiver to transfer and enabling the transceiver to determine the access link beam for transfer. This allows the transfer between the terminal and the network device to be completed by effectively utilizing the beam identifier. [Examples]

[0142] In some embodiments, the relationship between the beams includes the two beams having different directions, or the two beams having the same direction and different widths.

[0143] In some embodiments, the beam identifier that the network device instructs the transceiver indicates the corresponding beam identifier with a first number of bits, or the beam identifier that the network device instructs the transceiver indicates the corresponding beam identifier in a bitmap manner.
