Description

[Technical Field]

[0001] FIELD OF THE INVENTION Embodiments of the present invention relate to the field of communications technology. [Background technology]

[0002] Compared with the conventional 3G (third generation mobile communication technology) and 4G (fourth generation mobile communication technology) systems, the 5G (fifth generation mobile communication technology) system provides wider bandwidth and higher data rates, and can support more types of terminals and diverse industrial services.

[0003] As such, 5G systems are being deployed in traditional telecommunications spectrum as well as new spectrum that has significantly higher frequencies than the traditional telecommunications spectrum used by 3G and 4G systems. For example, 5G systems may be deployed in millimeter wave bands (e.g., 28 GHz, 38 GHz, 60 GHz and above).

[0004] According to the radio signal propagation rules, the higher the frequency of the carrier wave on which the radio signal is located, the greater the signal fading during propagation. Therefore, in actual deployment, how to enhance the cell coverage of the 5G system compared to the traditional 3G and 4G systems, especially for the 5G system deployed in the millimeter wave band, is an issue that needs to be resolved urgently.

[0005] The above description of the background art is merely for the purpose of explaining the configuration of the present invention more clearly and completely, and is provided for the understanding of those skilled in the art. These configurations described in the background art of the present invention should not be construed as being well known to those skilled in the art. Summary of the Invention [Problem to be solved by the invention]

[0006] In order to better solve the coverage problem in the actual deployment of cellular mobile communication systems, using a radio frequency repeater (RF relay / repeater) to amplify and forward communication signals between terminal devices and network devices is a relatively common deployment method. Radio frequency repeaters are relatively widely applied in the actual deployment of 3G systems and 4G systems. Generally, a radio frequency repeater is a device that amplifies and forwards signals between network devices and terminal devices in the radio frequency domain.

[0007] According to the discovery of the present inventors, the use of radio frequency repeaters to enhance coverage is one of the viable solutions to the coverage problem in the deployment of 5G systems. However, conventional radio frequency repeaters do not have the ability to communicate with network devices, and therefore cannot adjust transmission according to the actual situation of the network. Therefore, when configured in a 5G system, this repeater can enhance signal strength to a certain extent, but it does not have enough flexibility to adapt to complex environmental changes, and its transmission efficiency and transmission effect are lower than those of similar types of radio frequency repeaters deployed in 3G and 4G systems.

[0008] In view of at least one of the above problems, embodiments of the present invention provide an information indication method, a repeater, and a network device. The repeater has the ability to communicate with network devices, and when deployed in a network, can better enhance signal coverage and adapt to environmental changes (e.g., reduce interference to other network devices and terminal devices during transmission), thereby improving the transmission efficiency of the entire network. [Means for solving the problem]

[0009] In one aspect of an embodiment of the present invention, there is provided an information indication method, the method including a step in which a repeater acquires first information, and a step in which the repeater determines to perform reception or transmission on an access (AC) link using a first beam at a first time based on at least the first information and / or communication standard definition rules.

[0010] Another aspect of an embodiment of the present invention provides a repeater including an acquisition unit that acquires first information, and a decision unit that decides to perform reception or transmission on an access link using a first beam at a first time based on at least the first information and / or a communication standard definition rule.

[0011] Another aspect of an embodiment of the present invention provides an information indication method, the method including a step in which a network device transmits first information to a repeater, and the repeater determines to perform reception or transmission on an access (AC) link using a first beam at a first time based on at least the first information and / or a communication standard definition rule.

[0012] Another aspect of an embodiment of the present invention provides a network device including a transmitter that transmits first information to a repeater, and the repeater determines to perform reception or transmission on an access link using a first beam at a first time based on at least the first information and / or a communication standard definition rule.

[0014] One of the advantageous effects of the embodiment of the present invention is as follows: a repeater obtains first information, and determines to use a first beam at a first time to receive or transmit on an access (AC) link based on at least the first information and / or a communication standard definition rule, thereby enabling the repeater to determine AC link forwarding based on the first information and / or a communication standard definition rule, thereby better enhancing signal coverage and adapting to changes in the environment and main services within a cell, thereby improving the transmission efficiency of the entire network.

DETAILED DESCRIPTION OF THE INVENTION

[0020] The above and other features of the present invention will become apparent from the following description. In the specification and drawings, specific embodiments of the present invention are disclosed in detail, and some of the embodiments in which the principles of the present invention can be adopted are shown. However, the present invention is not limited to the described embodiments. The present invention includes all modifications, variations, and equivalents within the scope of the appended claims. Below, various embodiments of the present invention will be described with reference to the drawings. These embodiments are merely illustrative and do not limit the present invention.

[0021] In embodiments of the present invention, the terms "first," "second," etc. are used in titles to distinguish between different elements, but do not represent the spatial arrangement or temporal order of these elements, and these elements are not limited to these terms. The term "and / or" includes any and all combinations of one or more of the terms listed in the associated list. The terms "comprise," "include," "have," etc. refer to the presence of listed features, elements, elements, or components, but do not exclude the presence or addition of one or more other features, elements, elements, or components.

[0022] In the embodiments of the present invention, the singular forms "one," "the," etc., include the plural and should be understood broadly as "one kind" or "one class," and are not limited to "one." Furthermore, the term "said" should be understood to include both the singular and the plural, unless the context clearly indicates otherwise. Furthermore, the term "described in" should be understood to mean "described at least in part," and the term "based on" should be understood to mean "based at least in part," unless the context clearly indicates otherwise.

[0023] In embodiments of the present invention, the terms "communication network" or "wireless communication network" may refer to a network conforming to any communication standard, such as, for example, Long Term Evolution (LTE), Long Term Evolution Advanced (LTE-A, LTE-Advanced), Wideband Code Division Multiple Access (WCDMA), High-Speed ​​Packet Access (HSPA), etc.

[0024] Additionally, communications between devices in a communications system may occur according to any stage of communications protocol, including, but not limited to, 1G (generation), 2G, 2.5G, 2.75G, 3G, 4G, 4.5G, and 5G, New Radio (NR), and / or other currently known or future developed communications protocols.

[0025] In an embodiment of the present invention, the term "network device" refers to a device in a communication system that allows a terminal device to access the communication system and provides a service to the terminal device, and may include, but is not limited to, a base station (BS), an access point (AP), a transmission reception point (TRP), a broadcast transmitter, a mobility management entity (MME), a gateway, a server, a radio network controller (RNC), a base station controller (BSC), etc.

[0026] Among them, the base station may include, but is not limited to, a Node B (NodeB or NB), an evolved Node B (eNodeB or eNB), a 5G base station (gNB), etc., as well as a remote radio head (RRH), a remote radio unit (RRU), a relay, or a low-power node (e.g., femto, pico, etc.). The term "base station" may include some or all of these functions, and each base station may provide communication coverage for a particular geographic area. The term "cell" may refer to a base station and / or its coverage area, depending on the context in which the term is used.

[0027] In the embodiments of the present invention, the term "User Equipment" (UE) or "Terminal Equipment" (TE) refers to a device that connects to a communication network via, for example, a network device and receives network services. The terminal device may be fixed or mobile, and may also be referred to as a mobile station (MS), a terminal, a subscriber station (SS), an access terminal (AT), an IAB-MT, a station, etc.

[0028] Among them, the terminal device may include, but is not limited to, a mobile phone, a personal digital assistant (PDA), a wireless modulation / demodulation device, a wireless communication device, a handheld device, a machine-type communication device, a laptop computer, a cordless phone, a smartphone, a smart watch, a digital camera, etc.

[0029] Furthermore, for example, in a scenario such as the Internet of Things (IoT), the user device may be a monitoring or measurement device or apparatus, including, but not limited to, a Machine Type Communication (MTC) terminal, an in-vehicle communication terminal, an industrial wireless device, a surveillance camera, a Device to Device (D2D) terminal, a Machine to Machine (M2M) terminal, etc.

[0030] To further enhance coverage, 3GPP Rel-17 studies introduce an RF repeater to forward transmissions between a user equipment (UE) and a network device (base station). The RF repeater introduced in Rel-17 is transparent to the network device and the user equipment, i.e., the network device and the user equipment are unaware of the existence of the RF repeater.

[0031] 1 is a schematic diagram of an example of an application scenario of an embodiment of the present invention. As shown in FIG. 1, for convenience of explanation, one network device (for example, a 5G base station gNB) 101, one repeater 102, and one user equipment (UE) 103 are described as an example, but the present invention is not limited thereto.

[0032] As shown in Figure 1, a terminal device 103 establishes a connection and communicates with a network device 101. In order to improve communication quality, the channel / signal transmitted between the terminal device 103 and the network device 101 is forwarded via a repeater 102. The interaction of the channel / signal between the network device 101, the terminal device 103 and the repeater 102 all adopts a beam-based receiving and transmitting method.

[0033] 1, the network device 101 may have a cell / carrier, and the network device 101, the repeater 102, and the terminal device 103 can perform transmission / communication in the cell. However, the present invention is not limited thereto, and for example, the network device 101 may have another cell / carrier.

[0034] In an embodiment of the present invention, existing or future services can be performed between a network device and a terminal device, for example, these services may include, but are not limited to, enhanced mobile broadband (eMBB), massive machine-type communications (mMTC), highly reliable and low latency communications (URLLC), and vehicle-to-everything (V2X) communications.

[0035] Because a conventional repeater does not have the ability to communicate with a network device, although the conventional repeater can strengthen the signal strength, it does not have enough flexibility to respond to complex environmental changes. Therefore, when a conventional repeater is deployed in a 5G network (especially a high-frequency 5G network), it may cause unnecessary interference to other network devices and / or terminal devices, and may reduce the transmission efficiency (e.g., throughput) of the entire network. In order to make the forwarding of the conventional repeater more flexible to adapt to the characteristics of the 5G network, the network device needs to support the repeater and configure the forwarding of the repeater according to the network situation.

[0036] To enhance the coverage of 3GPP Rel-18 NR, a network-controlled repeater (NCR) is proposed to forward signals between network equipment and terminal equipment. To support the forwarding operation of the NCR, the NCR can directly communicate with the network equipment via a control link.

[0037] 2 is a schematic diagram of an example of an NCR according to an embodiment of the present invention. As shown in FIG. 2, an NCR 202 is configured between a network device 201 and a terminal device 203. The NCR 202 may include two modules / components: a repeater mobile terminal (NCR-MT) and a repeater forwarding module (NCR-Fwd). The NCR-Fwd is also referred to as an NCR-RU routing unit (NCR-RU). The NCR-MT is used to communicate with the network device, and the NCR-Fwd is used to forward signals between the network device and the terminal device.

[0038] As shown in Fig. 2, the NCR of the embodiment of the present invention may have three links, namely, a control link (C-link), a backhaul link (BH link) for forwarding, and an access link (AC link). Here, the C-link is used for communication between the NCR and the network device. The BH link is used by the repeater to receive signals to be forwarded from the network device or forward signals from the terminal device to the network device. The AC link is used by the repeater to forward signals from the network device to the terminal device or receive signals to be forwarded from the terminal device.

[0039] According to the inventors' recognition, the 5G system is more complex than the conventional 3G, 4G systems, etc., and needs to support more types of services and terminal types, and also needs to be deployed in various frequency bands and scenarios, etc. Compared with the conventional RF repeater, the NCR needs to have a beam-based function.

[0040] Fig. 3 is a schematic diagram of an example of NCR forwarding according to an embodiment of the present invention. As shown in Fig. 3, the repeater forwards a signal from a network device using a transmit beam on an AC link. Fig. 4 is a schematic diagram of another example of NCR forwarding according to an embodiment of the present invention. As shown in Fig. 4, the repeater receives a signal for forwarding to a network device using a receive beam on an AC link.

[0041] However, according to the discovery of the inventors of the present invention, there is currently no concrete solution for how a repeater determines information such as the beam of an AC link, that is, how a repeater determines transmission information (beam, time, signal direction, etc.) of an AC link is a problem that needs to be solved as soon as possible.

[0042] Furthermore, the serving process allows conflicts between various service types and terminal types, and provides a systematic conflict resolution solution. For example, when URLLC service data with high reliability and delay requirements arrives, ongoing eMBB service data transmission may be interrupted or discarded in order to ensure timely and reliable transmission of high-priority URLLC service data. Furthermore, due to the advanced and complex functionality of the 5G system, the network side may perform operations such as reconfiguration and overwriting when configuring and scheduling. The main purpose of NCR is to cover areas with poor network signal quality, and the terminals served by NCR may be various terminals. Therefore, signals transmitted by NCR for interaction between the network side and the terminal side may have different priorities.

[0043] Based on the above understanding, the inventor further believes that considering how NCRs avoid or handle configuration conflicts such as beam direction in AC links is an issue that needs to be resolved more urgently in the process of designing NCRs that provide services for 5G networks.

[0044] Various aspects of embodiments of the present invention will now be described with reference to the drawings, which are merely illustrative and not limiting of the present invention.

[0045] In an embodiment of the present invention, a repeater can communicate with a network device, and the repeater can receive a communication channel / signal transmitted by the network device and obtain information transmitted from the network device to the repeater by demodulating / decoding the channel / signal. This signal processing process is hereinafter referred to as "communication." The repeater can forward a channel / signal transmitted between a network device and a terminal device, and the repeater can amplify or process the channel / signal without demodulating / decoding it. This signal processing process is hereinafter referred to as "forwarding." "Communication" and "forwarding" are collectively referred to as "transmission." Furthermore, "performing transmission or reception over an AC link" may be equivalent to "performing forwarding over an AC link," and "performing transmission or reception over a control link" may be equivalent to "performing communication over a control link." The above terms are used for convenience of explanation and do not limit the present invention.

[0046] For convenience of explanation, a channel / signal for direct communication between a network device and a repeater, or between a third device (e.g., a terminal device) and a repeater, may be referred to as a communication signal. When transmitting a communication signal, the repeater needs to perform encoding and / or modulation, and when receiving a communication signal, the repeater needs to perform decoding and / or demodulation. Also, a channel / signal forwarded via a repeater may be referred to as a transport signal. The repeater may perform signal processing such as amplification on the forwarded signal, but does not perform decoding and / or demodulation.

[0047] In an embodiment of the present invention, a repeater may be expressed as a repeater, radio frequency repeater, forwarder, radio frequency forwarder, or as a repeater node, repeater node, forwarder node, or as a smart repeater, smart repeater, smart forwarder, smart repeater node, smart repeater node, smart forwarder node, etc., but the present invention is not limited thereto.

[0048] In the embodiments of the present invention, the network device may be a device of a serving cell of a terminal device, a device of a cell in which a repeater is located, a device of a serving cell of a repeater, or a parent node of a repeater. The present invention is not limited to the name of the repeater, and any device capable of realizing the above functions is included in the scope of the repeater according to the present invention.

[0049] In an embodiment of the present invention, a beam may be represented as a reference signal (RS), a transmission configuration indication (TCI), a spatial domain filter, etc., or may be represented as a beam index, a reference signal index, a transmission configuration indication index, a spatial domain filter index, etc. The above reference signal may be, for example, a channel state information reference signal (CSI-RS), a sounding reference signal (SRS), an RS for a repeater, an RS transmitted by a repeater, etc. The above TCI may be represented as a TCI state. The embodiment of the present invention is not limited thereto.

[0050] Example 1 The embodiment of the present invention provides an information indication method and is explained from the repeater side.

[0051] 5 is a schematic diagram of an example of an information indication method according to an embodiment of the present invention. As shown in FIG. 5, the method includes the following steps:

[0052] Step 501: The repeater acquires first information.

[0053] Step 502: The repeater determines, based on at least the first information and / or communication standard definition rules, to perform reception or transmission on an access (AC) link using a first beam at a first time.

[0054] It should be noted that the above-mentioned FIG. 5 merely illustrates an example of the present invention, and the present invention is not limited thereto. For example, the execution order of various steps may be appropriately adjusted, some other steps may be added, or some steps may be removed. Those skilled in the art can make appropriate modifications based on the above content, and are not limited to the description of the above-mentioned FIG. 5.

[0055] This allows the repeater to determine AC link forwarding based on the first information and / or communication standard definition rules, thereby better enhancing signal coverage and responding to changes in the environment and main services within the cell, thereby improving the transmission efficiency of the entire network.

[0056] In some embodiments, the repeater determines the first beam and / or the first time based on at least one of communication standard definition rules, dynamic signaling, semi-static signaling, and operation, administration and maintenance (OAM) configuration information.

[0057] For example, the first beam may be determined by the NCR itself based on a predetermined rule in the standard protocol. Alternatively, for example, the NCR may set the number of beams for AC link transmission at the factory, and the NCR may select one of the beams. Alternatively, for example, the NCR may determine the first beam by receiving system information and / or utilizing some other information. Determining the first beam according to a standard-defined rule or a factory setting can reduce the complexity of the NCR and the cost of the NCR device. For example, such an embodiment can be applied to a common signal that is periodically transmitted.

[0058] Also, for example, the network side (gNB or OAM) configures / instructs a first beam for NCR. This first beam may be indicated by dynamic signaling, semi-static signaling, or OAM configuration information. Configuring / instructing this first beam for NCR by the network side can provide greater flexibility so that the network side can configure / instruct the first beam for NCR according to actual needs. For example, such an embodiment can be applied to aperiodic signals, etc.

[0059] In some embodiments, the first time period includes at least one time unit, where the at least one time unit is contiguous in the time domain, or the at least one time unit is discontinuous in the time domain, such as a subframe, a slot, a symbol, a mini-slot, etc.

[0060] In some embodiments, the first information is conveyed by semi-static signaling, and / or the first information is configured by an OAM entity, and / or the first information is conveyed by a physical downlink control channel (PDCCH) or dynamic signaling.

[0061] In some embodiments, the first information is used to indicate a first time, and / or the first information is used to indicate a first beam, and / or the first information is used to instruct a repeater to perform reception or transmission on an access link. The flexibility of the indication of the first information can easily realize the reuse of existing signaling and / or indication information in 5G systems in different application scenarios, thereby reducing standardization work, accelerating the standardization process, accelerating industrial upgrades, and enabling the telecommunications industry to adapt more quickly and better to emerging applications and emerging areas.

[0062] For example, the first beam is determined by the NCR according to a predefined rule, and the first time is indicated by first information (e.g., indicated by receiving dynamic signaling, semi-static signaling, or OAM configuration).

[0063] Also, for example, the first time is determined by the NCR according to a predefined rule, and the first beam is indicated by first information (e.g., indicated by receiving dynamic signaling, semi-static signaling, or OAM configuration).

[0064] Also, for example, both the first beam and the first time are determined by the NCR according to a predefined rule, and the repeater is instructed to receive or transmit on the access link by first information (e.g., indicated by receiving dynamic signaling, semi-static signaling, or OAM configuration).

[0065] In some embodiments, the designation of the first beam is based on a beam index, and / or the designation of the first beam is based on a synchronization signal block (SSB) index, and / or the designation of the first beam is based on a reference signal index. The designation of the first beam based on a beam index may be a beam serial number of an AC link. The designation of the first beam based on an SSB index or a reference signal index may be that the first beam is named by an SSB index or a reference signal index.

[0066] The indication of the first beam may be to indicate a beam index corresponding to the first beam, and / or to indicate an SSB index corresponding to the first beam, and / or to indicate a reference signal index corresponding to the first beam. The beam and the beam index (or the SSB index or the reference signal index) have a one-to-one correspondence. The correspondence between the beam and the beam index (or the SSB index or the reference signal index) may be determined by the repeater or indicated to the repeater by the network side. Once determined, the correspondence between the beam and the beam index (or the SSB index or the reference signal index) does not change, or does not change until the repeater is reset and / or reconfigured and / or re-indicated and / or restarted or next startup.

[0067] In some embodiments, the first information is used to indicate that the repeater is to perform reception or transmission on the access link using a first beam at a first time.

[0068] For example, the first time, the first beam, and the transfer direction are all indicated by the first information.

[0069] In some embodiments, the first information is used to indicate a first time and a first beam, and the repeater acquires the second information, which is used by the repeater to determine at least to perform reception or transmission on the access link using the first beam at the first time.

[0070] In some embodiments, the second information is conveyed by dynamic signaling and / or semi-static signaling, and / or the second information is configured by an OAM entity.

[0071] For example, a first time and a first beam are indicated by first information, and other information (such as a forwarding direction) is indicated by second information.

[0072] In some embodiments, the second information indicates at least that the first time includes uplink time units and / or downlink time units and / or flexible time domains, e.g., time division duplex (TDD) uplink / downlink configuration information.

[0073] For example, when instructing a beam, the network side may simultaneously instruct the transmission direction of the beam.

[0074] Also, for example, there is consistency in transmission and reception of the AC link, i.e., there is consistency in the beam that transmits the uplink or downlink. In this case, even if the network side does not specify whether this beam is for the uplink or downlink, for example, it can instruct only one beam (e.g., instruct the index of this beam), and there will be no ambiguity between the network side and the NCR as to which beam this is. In this case, in a specific embodiment, the NCR may determine / decide the propagation direction of the signal in which the instructed beam is used for transmission, in combination with other information (e.g., TDD config). According to such an embodiment, it is possible to reduce duplicate instructions.

[0075] In some embodiments, the repeater determines to perform access link reception using a first beam in an uplink time unit of a first time.

[0076] In some embodiments, the repeater determines to perform transmission on the access link using a first beam in a downlink time unit of a first time.

[0077] In some embodiments, the repeater determines to perform reception or transmission on the access link using the first beam in at least one flexible time region at a first time.

[0078] In some embodiments, the repeater determines not to receive and not to transmit on the access link in at least one flexible time region of the first time.

[0079] In some embodiments, the first information is used to indicate a first time, the first time being associated with a first signal, the first signal not being generated by the repeater and / or the repeater not performing demodulation and decoding on the first signal, i.e., the first signal being a transport signal as described above.

[0080] For example, the first information indicates the time (first time) at which the common signal is transmitted, while the first beam is determined by the NCR itself, or determined according to a predefined rule, or determined randomly. The repeater does not perform signal processing such as demodulation on the signal it transmits; instead, the repeater only amplifies the signal it transmits. The performance of the beam used by the repeater in the AC link can be evaluated by measurements by a third-party device (e.g., a terminal device) and / or measurements by the network side. The repeater does not measure the signal it transmits. Therefore, the network side's instruction and configuration of the repeater's transmission behavior is not affected by the specific correspondence between the beam name and the beam. By the NCR determining the beam itself, the overhead of instruction / configuration signaling on the network side can be reduced, thereby reducing the complexity on the network side.

[0081] In some embodiments, the repeater determines a first beam, the first beam being associated with a first signal, and the repeater determines to receive or transmit the first signal on the access link using the first beam at a first time.

[0082] In some embodiments, the first signal includes at least an SSB with index n, the first information includes system information, and the first time includes at least a time unit corresponding to SSB index n.

[0083] In some embodiments, the repeater determines an SSB index n for transmitting on the access link.

[0084] In some embodiments, the SSB index n is configured or indicated by the network side, and / or the SSB index n is predefined by a communication standard, and / or the SSB index n is pre-configured in the repeater.

[0085] In some embodiments, the repeater determines a first beam for transmitting an SSB with index n on the access link.

[0086] In some embodiments, the repeater determines the number N of SSBs and / or the indices of the N SSBs to be transmitted on the access link, where the SSB index n is one of the indices of the N SSBs. The number N of SSBs and / or the indices of the N SSBs may be preset, or the number N of SSBs and / or the indices of the N SSBs may be predefined by a communication standard, or the number N of SSBs and / or the indices of the N SSBs may be configured or instructed for the repeater by the network side.

[0087] In some embodiments, the value of the number of SSBs N is preset. The repeater reports the number of SSBs N to the network side. The network device configures / indicates the indexes of the N SSBs for the repeater.

[0088] In some embodiments, the repeater determines N beams for transmitting N SSBs on the access link and determines a correspondence between the N beams and the N SSBs.

[0089] For example, N may be the number of beams used to transmit SSBs, and / or N may be the number of transmission beams that the repeater supports in the AC link, and / or N may be the number of transmission beams that the repeater uses in the AC link.

[0090] In some embodiments, the repeater determines the N beams for transmitting the N SSBs on the access link in accordance with network-side configuration and / or instructions, or the repeater determines the N beams for transmitting the N SSBs on the access link in accordance with communication standard-defined rules, or the repeater independently determines the N beams for transmitting the N SSBs on the access link, e.g., communication standard-defined rules dictating that SSBs with smaller index numbers correspond to beams with smaller index numbers.

[0091] In some embodiments, the first beam has a one-to-one correspondence with the SSB index n, and the one-to-one correspondence remains unchanged until the repeater is restarted and / or reconfigured. In this way, ambiguity can be avoided when the network side configures / instructs the beam to be forwarded on the AC link for NCR.

[0092] For example, the NCR decides on its own which beam to use and does not change it once it has been decided.

[0093] In some embodiments, the first time further includes a time unit or a random access opportunity (RACH occasion) for transmitting a random access preamble (RACH preamble) corresponding to the SSB index n, and the first signal further includes a signal transmitted using time domain resources and / or frequency domain resources corresponding to the time unit or the random access opportunity (RACH occasion) for transmitting a random access preamble (RACH preamble) corresponding to the SSB index n.

[0094] In some embodiments, the first signal comprises: Synchronization signal (SS), Synchronous Signal Block (SSB), System Information Block (SIB), Main Information Block (MIB), Msg1 (Random Access Channel, RACH), Msg2, Msg3, Msg4, Msg5, a Physical Downlink Control Channel (PDCCH) for scheduling (or triggering) Msg1 and / or Msg2 and / or Msg3 and / or Msg4 and / or Msg5; a Physical Downlink Shared Channel (PDSCH) for carrying Msg2 and / or Msg4; a Physical Uplink Shared Channel (PUSCH) for carrying Msg3 and / or Msg5; Channel State Information Reference Signal (CSIRS), Sounding Reference Signal (SRS), Beam Failure Recovery (BFR), A Physical Uplink Control Channel (PUCCH) for carrying Beam Failure Recovery (BFR); ACK / NACK information, a Physical Uplink Control Channel (PUCCH) for carrying ACK / NACK information; a scheduling request (SR), or It includes or relates to at least one of a signal, channel, or information of a physical uplink control channel (PUCCH) for carrying SR.

[0095] In some embodiments, the repeater determines, based on at least the first information, to receive or transmit a first signal on the access link using a first beam at a first time.

[0096] In some embodiments, the first information includes time domain and / or frequency domain location information where the first signal is located, and / or the first information is carried by one or more signalings.

[0097] In some embodiments, the first information includes at least system information, and the repeater determines to receive or transmit a signal related to the first signal at the first time based on at least the first information.

[0098] Although the first information, the first beam, the first time, and the like have been briefly described above, the present invention is not limited to this.

[0099] Because the AC link is the NCR's transmission link, the NCR may or may not know what signal it is transmitting. In other words, if the NCR does not know what signal it is transmitting, it does not affect the NCR's transmission of the signal.

[0100] The network side may configure the NCR to transmit signals in a specified transmission direction (e.g., uplink or downlink, or from the network side to the terminal side, or from the terminal side to the network side) using a specified beam at a specified time. In this way, the complexity of the communication protocol can be reduced, the implementation cost of the NCR can be reduced, and the price-performance ratio of the NCR device can be improved so that the NCR device can provide better and more actual network services.

[0101] Meanwhile, the NCR may identify the type of signal it is transmitting, for example, a common signal (e.g., SS, SSB, SIB, MIB, RACH, etc.) or another signal (e.g., a dedicated signal of a terminal served by the NCR, etc.). In this way, an NCR device having such a capability can obtain information regarding signal transmission autonomously to some extent, reducing the complexity of the network side device, reducing the cost of the network device, and reducing the configuration information regarding the interaction between the network side device and the NCR. Therefore, more time domain / frequency domain / spatial domain resources can be used to transmit service data, and spectrum utilization efficiency can be improved.

[0102] The following provides a more general description of how the NCR avoids or handles collisions of configurations such as beam pointing on the AC link.

[0103] In some embodiments, the repeater obtains third information, the third information relating to a second time, the second time at least partially overlapping with the first time.

[0104] The third information is used to further indicate a second beam forwarded by the repeater on the access link, and / or the third information is used to further indicate a forwarding direction of the repeater on the access link during the at least partially overlapping time period, and / or the third information is used to further indicate a transmission direction and / or an on / off state associated with the at least partially overlapping time period.

[0105] The following will first briefly explain the case where the second beam is different from the first beam, i.e., the beams collide. The following will explain, as an example, the introduction of the concept of priority into collision resolution, where the priority of the first beam is higher than or equal to the priority of the second beam, but the present invention is not limited thereto.

[0106] In some embodiments, the third information is used to at least indicate that the repeater performs transmission on the access link using a second beam at a second time, the transmission direction being consistent or inconsistent with the transmission direction determined by the repeater at the first time, and the second beam being the same as or different from the first beam. The repeater performs reception or transmission on the access link using the first beam at the first time.

[0107] For example, the repeater determines, based on at least the first information, to perform reception on the access link using a first beam at a first time, the third information is used to indicate that the repeater will perform reception on the access link using a second beam at a second time, and the repeater will perform reception on the access link using the first beam at the first time.

[0108] Also, for example, the repeater determines, based on at least the first information, to perform transmission on the access link using a first beam at a first time, and the third information is used to indicate that the repeater will perform transmission on the access link using a second beam at a second time, and the repeater performs transmission on the access link using the first beam at the first time.

[0109] Also, for example, the repeater determines, based on at least the first information, to perform reception on the access link using a first beam at a first time, the third information is used to indicate that the repeater will perform transmission on the access link using a second beam at a second time, and the repeater will perform reception on the access link using the first beam at the first time.

[0110] Also, for example, the repeater determines, based on at least the first information, to perform transmission on the access link using a first beam at a first time, the third information is used to indicate that the repeater will perform reception on the access link using a second beam at a second time, and the repeater performs transmission on the access link using the first beam at the first time.

[0111] In some embodiments, the priority of the first beam is configured and / or indicated by the network side, or the priority of the first beam is defined by a communication standard, or the priority of the first beam is determined by the repeater based on at least the first information.

[0112] In some embodiments, the priority of at least one time unit included in the first time period is higher than or equal to a preset priority, or higher than or equal to the priority of any time unit in the second time period, or higher than or equal to the priority of any time unit in the at least partially overlapping time period. In conflict resolution, the forwarding priority determined by the repeater associated with the first time period is higher than or equal to the forwarding priority associated with the second time period.

[0113] For example, the priority of the time unit may be configured and / or indicated by the network side, or the priority of the time unit may be defined by a communication standard, or the priority of the time unit may be determined by at least a signal associated with the time unit.

[0114] In some embodiments, the third information is used to indicate a second beam transmitted by the repeater on the access link, where the third information is used to indicate that the repeater receives or transmits a second signal on the access link using the second beam at a second time, the priority of the second signal being lower than or equal to the priority of the first signal, and in contention resolution, the transmission priority associated with the first signal determined by the repeater is higher than or equal to the transmission priority associated with the second signal.

[0115] In some embodiments, the priority of the first signal and / or the second signal is defined by a communication standard, or the priority of the first signal and / or the second signal is configured and / or indicated by the network side.

[0116] In some embodiments, the first signal has the highest priority.

[0117] For example, the priority of the first signal may be equal to or higher than the priority of other signals received or transmitted by the NCR on the AC link, or the priority of the first signal may be equal to or higher than other signals received or transmitted by the NCR on the AC link within a first time period, or the priority of signals received or transmitted by the NCR on the AC link may be divided into M levels, with the first signal having the highest priority.

[0118] In some embodiments, the first information is conveyed by semi-static signaling and / or configured by an OAM entity, and the third information is conveyed by dynamic signaling. For example, the priority of the first information conveyed by semi-static signaling or configured by OAM is higher than or equal to the priority of the third information conveyed by dynamic signaling. In conflict resolution, the forwarding priority associated with the first information conveyed by semi-static signaling or configured by OAM is higher than or equal to the forwarding priority associated with the third information conveyed by dynamic signaling.

[0119] This can effectively guarantee the transmission of more important common signals in the event of a collision, thereby avoiding adverse consequences such as failure of terminal device access to the network, link failure, beam failure, etc., caused by poor transmission quality of the common signals. Semi-static signaling can be used to indicate transmissions related to relatively important and periodically transmitted or received common signals, such as SSB signals, SIB signals, and signals that may include RACH. Dynamic signaling can be used to indicate transmissions related to dynamic or more dynamic data, such as PDSCH and / or PUSCH of terminal devices served by the NCR.

[0120] In some embodiments, the first information is conveyed by dynamic signaling, and the third information is conveyed by semi-static signaling and / or indicated by OAM, or the third information is conveyed by dynamic signaling. The semi-static signaling includes MAC CE and / or RRC signaling. The repeater receives the third information before receiving the first information.

[0121] This allows information to be overwritten by dynamic signaling. For example, in this way, it is possible to ensure that more important signals to be transferred are transferred reliably and efficiently. If a URLLC service that requires both reliability and delay arrives at one of the terminals served by the NCR, it is necessary to transmit or receive a URLLC service signal. The network side can use dynamic signaling to rewrite the transfer configuration / instruction to ensure reliable and timely transfer of URLLC traffic signals.

[0122] In some embodiments, the first information is conveyed by semi-static signaling, the third information is conveyed by semi-static signaling and / or indicated by OAM and / or conveyed by dynamic signaling, the semi-static signaling including MAC CE and / or RRC signaling, and the repeater receives the third information before receiving the first information.

[0123] This allows information to be rewritten (or updated, or reconfigured, etc.) by semi-static signaling. For example, when the network side adjusts the transmission of a periodically transmitted common signal in this way, the network side can rewrite the transmission configuration of the periodically transmitted common signal so that the repeater adapts to the forwarding of the adjusted common signal.

[0124] The above embodiments may be combined, for example, to provide better flexibility for repeater forwarding and to ensure forwarding of important signals, and can be applied to different scenarios.

[0125] The following will further briefly explain the case where the transmission directions do not match, that is, the transmission directions collide.

[0126] In some embodiments, the third information is used to further indicate a transmission direction and / or an on / off state associated with the at least partially overlapping time period, where the third information is used to indicate at least a signal transmission direction for one time unit during the at least partially overlapping time period, and the signal transmission direction for the one time unit does not coincide with a signal transmission direction on an access link using the first beam at the first time period determined by the repeater based on the first information.

[0127] In some embodiments, the repeater receives or transmits on the access link using a first beam at a first time.

[0128] For example, the repeater determines to perform reception on the access link using a first beam at a first time (uplink), and the third information is used to indicate that at least one time unit of the at least partially overlapping times is a downlink time unit or a flexible time unit.

[0129] Also, for example, the repeater decides to perform transmission on the access link using the first beam at the first time (downlink), and the third information is used to indicate that at least one time unit of the at least partially overlapping times is an uplink time unit or a flexible time unit.

[0130] In some embodiments, the repeater does not receive and / or transmit on the access link within the time unit in which the signal transmission directions do not match.

[0131] For example, the repeater determines to perform reception on the access link using a first beam at a first time (uplink), and the third information is used to indicate that at least one of the time units included in the first time is a downlink time unit or a flexible time unit, and the repeater does not perform reception in the downlink time unit or the flexible time unit, or does not perform reception at the first time.

[0132] Also, for example, the repeater decides to perform transmission on the access link (downlink) using the first beam at the first time, and the third information is used to indicate that at least one of the time units included in the first time is an uplink time unit or a flexible time unit, and the repeater does not perform transmission in the uplink time unit or the flexible time unit, or does not perform transmission at the first time.

[0133] The following briefly describes the case of OFF time, i.e., transfer time conflicts with OFF time.

[0134] In some embodiments, the third information is used to indicate that at least one time unit included in the first time is not used for reception or transmission, and the at least one time unit not used for reception or transmission is an OFF time unit, a sleep / dormancy time unit, or a null time unit.

[0135] In some embodiments, the repeater receives or transmits on the access link using the first beam at the first time, for example, the first signal is very important for initial access of the terminal device, and therefore needs to be forwarded even when the repeater is off.

[0136] In some embodiments, the repeater does not receive and / or transmit on the access link within the time units that indicate it will not be used for receiving or transmitting, thereby allowing the NCR to avoid transmissions during the off-time and improve energy efficiency.

[0137] In some embodiments, the third information is carried by signaling, and the signaling is used to indicate at least an off time. For example, the signaling is further used to indicate a TDD UL DL configuration, where OFF is one state of a time unit in the TDD UL DL configuration. For example, the signaling is dedicated signaling used to indicate the off time. For example, the signaling is DRX signaling.

[0138] In some embodiments, the signaling is further used to indicate uplink time units and / or downlink time units and / or flexible time units, for example, the signaling is used to indicate at least a TDD UL DL configuration.

[0139] The following briefly describes the C-link case, i.e., the forwarding link conflicts with the control link.

[0140] In some embodiments, the repeater obtains fourth information, the fourth information relating to a third time, the third time at least partially overlapping with the first time.

[0141] In some embodiments, the fourth information is used to indicate at least that the repeater receives a signal from the network side or transmits a signal to the network side on the control link at the third time.

[0142] In some embodiments, the repeater receives a signal from the network side or transmits a generated signal to the network side on the control link at a third time.

[0143] This allows the NCR to guarantee a connection with the network device with priority, and to avoid the influence on the AC link transfer due to the connection with the network side being unreliable.

[0144] For example, the repeater determines, based on at least the first information, to perform reception on the access link using a first beam at a first time, the fourth information is used to indicate that the repeater performs reception on the control link at a third time, and the repeater does not perform reception on the access link at least partially overlapping times.

[0145] Also, for example, the repeater determines, based on at least the first information, to perform transmission on the access link using a first beam at a first time, the fourth information is used to indicate that the repeater performs transmission on the control link at a third time, and the repeater does not perform transmission on the access link at an at least partially overlapping time.

[0146] Also, for example, the repeater determines, based on at least the first information, to perform reception on the access link using a first beam at a first time, and the fourth information is used to indicate that the repeater performs reception on the control link at a third time, and the repeater does not perform reception on the access link at the first time.

[0147] Also, for example, the repeater determines, based on at least the first information, to perform transmission on the access link using a first beam at a first time, and the fourth information is used to indicate that the repeater will perform transmission on the control link at a third time, and the repeater will not perform transmission on the access link at the first time.

[0148] In some embodiments, the repeater receives or transmits on the access link using a first beam at a first time.

[0149] This allows the NCR to prioritize the stability of the AC link and protect the transmission of terminal devices with high priority, for example, terminal devices with URLLC traffic.

[0150] For example, the repeater determines, based on at least the first information, to perform reception on the access link using a first beam at a first time, the fourth information is used to indicate that the repeater receives a signal from the network side on the control link at a third time, and the repeater does not receive a signal from the network side on the control link at an at least partially overlapping time.

[0151] Also, for example, the repeater determines, based on at least the first information, to perform transmission on the access link using the first beam at the first time, the fourth information is used to indicate that the repeater will transmit a signal to the network side on the control link at the third time, and the repeater does not transmit a signal to the network side on the control link at a time that at least partially overlaps.

[0152] Also, for example, the repeater determines, based on at least the first information, to perform reception on the access link using the first beam at the first time, and the fourth information is used to indicate that the repeater will receive a signal from the network side on the control link at the third time, and the repeater will not receive a signal from the network side on the control link at the third time.

[0153] Also, for example, the repeater determines to perform transmission on the access link using the first beam at the first time based on at least the first information, the fourth information is used to indicate that the repeater will transmit a signal to the network side on the control link at the third time, and the repeater will not transmit a signal to the network side on the control link at the third time.

[0154] In some embodiments, the fourth information may include information indicating that the repeater: Msg1 (RACH, preamble), BFR, S.R., A / N, SRS, Msg3, Msg5, Aperiodic CSI reporting, or It is used to indicate that at least one of the signals of the semi-persistent CSI report is generated and transmitted to the network side at the third time.

[0155] In some embodiments, the fourth information may include information indicating that the repeater: Msg2, Msg4, a PDCCH for scheduling Msg2 and / or Msg4; CSIRS, or is used to indicate receiving at least one of the signals BFRR from the network side at a third time; The signal is demodulated or decoded by the repeater.

[0156] Although the above is a general description of how the NCR handles collisions of configurations such as beam direction in the AC link, the present invention is not limited thereto. To avoid collisions, the network side and the repeater may follow specific policies or actions.

[0157] The following is a brief description of the network side's operation for avoiding collisions.

[0158] In some embodiments, the network side does not send the indication information that does not match the first information.

[0159] In some embodiments, the network side does not instruct the repeater to transmit or receive using a beam other than the first beam at the first time.

[0160] In some embodiments, the network side does not indicate that the first time period is an OFF time period.

[0161] In some embodiments, when the first information is used to at least instruct the repeater to perform reception on the access link using the first beam at the first time, the network side does not instruct that the first time includes downlink time units and / or flexible time units.

[0162] In some embodiments, when the first information is used to at least instruct the repeater to perform transmission on the access link using the first beam at the first time, the network side does not instruct that the first time includes uplink time units and / or flexible time units.

[0163] The operation of the repeater to avoid contention will be briefly described below.

[0164] In some embodiments, the repeater does not expect to be indicated any indication information that does not match the first information.

[0165] In some embodiments, the repeater does not expect to be instructed to transmit or receive using a beam other than the first beam at the first time.

[0166] In some embodiments, the repeater does not expect the first time to be indicated as an OFF time.

[0167] In some embodiments, when the first information is used to instruct at least the repeater to perform reception on the access link using the first beam at the first time, the repeater does not expect to be instructed that the first time includes downlink time units and / or flexible time units.

[0168] In some embodiments, when the first information is used to at least instruct the repeater to perform transmission on the access link using the first beam at the first time, the repeater does not expect to be instructed that the first time includes uplink time units and / or flexible time units.

[0169] The above provides a general description of conflict handling or avoidance, and the following provides further information on priority.

[0170] In some embodiments, this may be expressed as beam priority, i.e., some beams have a higher priority than others.

[0171] For example, beams used to transmit some signals have a high priority, e.g., beams used to transmit high-priority signals such as SSB.

[0172] Also, for example, the network side configures some beams to have a high priority, for example, by specifying a scheduling index for some beams, or the network side configures or indicates the priority of the beams.

[0173] It may also be pre-set, for example, so that beams indicated by some signaling have a higher priority, for example, beams configured by OAM have a higher priority, and / or beams indicated semi-statically have a higher priority, and / or beams indicated dynamically have a higher priority.

[0174] In some embodiments, the priority of the transmitted signal may be indicated, i.e., the transmitted signal itself may have a priority.

[0175] For example, signals that may have a high priority include at least one of SS, SSB, SIB, MIB, RACH, PDCCH for scheduling Msg2 and / or Msg3 and / or Msg4 and / or Msg5, PDSCH for carrying Msg2 and / or Msg4, PUSCH for carrying Msg3 and / or Msg5, CSIRS, SRS, etc. Note that signals other than the above may also be used, and the present invention is not limited to these.

[0176] Also, for example, the NCR may identify a signal with a high priority, in which case, if the beam used to transport this signal collides with other beams, the NCR will transmit and receive using the beam transporting the signal.

[0177] Also, for example, the NCR may distinguish between a signal having a high priority and some or all of the other signals, and in this case, if the beam used to forward this signal collides with other beams (e.g., beams forwarding some or all of the other signals or beams that do not determine the forwarded signal), the NCR will transmit and receive using the beam forwarding the signal.

[0178] In addition, for example, a signal used by a terminal device served by an NCR to report a beam failure report (BFR) may also have a higher priority, so that the network side can receive and process the BFR from the terminal side in a timely manner, thereby avoiding further large-scale link failures, etc.

[0179] Also, for example, the priority of a signal is indicated by the network side.

[0180] In some embodiments, the information may be expressed as an indication / configuration of signaling priority.

[0181] For example, a beam configured by OAM has a higher priority, and / or a semi-statically indicated beam has a higher priority, and / or a dynamically indicated beam has a higher priority, etc.

[0182] Also, for example, most of the important signals in the above example relate to important processes and capabilities of the served terminal equipment, such as initial access, channel tracking, channel measurement, etc. Therefore, semi-static signaling or signaling configured by OAM may have a high priority.

[0183] Also, for example, if a terminal device served by an NCR has a service that requires higher reliability and delay, the network side may send dynamic signaling to indicate a new transmission beam to the NCR. In this case, the priority may be classified into three classes, for example, the beam used to transmit SSB, etc. has the highest priority, the dynamic override has the next highest priority, and other instructions have the lowest priority.

[0184] In some embodiments, this may be indicated as a priority of the transfer direction, i.e., the transfer direction has priority.

[0185] For example, beam collisions may occur between uplink and downlink transmissions, giving the downlink transmission beam higher priority, giving the network side higher priority in communication, and ensuring service for more terminal devices served by the network device.

[0186] Also, for example, in the case of a collision of beam forwarding directions, the uplink forwarding beam may be given higher priority so that the network side can timely obtain the requested or reported information of the terminal device served by the NCR.

[0187] In some embodiments, the priority may be indicated as the time unit / period in which the beam is used or forwarded.

[0188] For example, the NCR may determine (based on received instructions or system information it has acquired) at what times more important signals need to be transmitted, and these times or periods have a higher priority, and the beams associated with these times or periods have a higher priority in beam collisions.

[0189] The above-described embodiments are merely illustrative of the present invention, and the present invention is not limited thereto. Appropriate modifications may be made based on the above-described embodiments. For example, each of the above-described embodiments may be used alone, or one or more of the above-described embodiments may be used in combination.

[0190] According to an embodiment of the present invention, a repeater acquires first information, and determines to use a first beam at a first time to receive or transmit on an access (AC) link based on at least the first information and / or a communication standard definition rule, thereby enabling the repeater to determine AC link forwarding based on the first information and / or a communication standard definition rule, thereby better enhancing signal coverage and adapting to changes in the environment and main services within a cell, thereby improving the transmission efficiency of the entire network.

[0191] <Example 2> An embodiment of the present invention provides a repeater, which may be, for example, the above-mentioned NCR, a network device or terminal device having a forwarding function, or one or more elements or components configured in the NCR, the network device, or the terminal device.

[0192] 6 is a schematic diagram of an example of a repeater according to an embodiment of the present invention. The principle of solving the problem of the repeater is the same as that of the method of embodiment 1, so that the specific implementation may refer to embodiment 1, and the description of the same content will be omitted.

[0193] As shown in FIG. 6, a repeater 600 according to an embodiment of the present invention includes the following components:

[0194] The acquisition unit 601 acquires the first information.

[0195] The decision unit 602 decides to perform reception or transmission on the access link using the first beam at the first time based on at least the first information and / or communication standard definition rules.

[0196] In some embodiments, the determination unit 602 determines the first beam and / or the first time based on at least one of communication standard definition rules, dynamic signaling, semi-static signaling, and operation, administration and maintenance (OAM) configuration information.

[0197] In some embodiments, the first time period includes at least one time unit, and the at least one time unit is contiguous or discontinuous in the time domain.

[0201] In some embodiments, the first information is used to indicate that the repeater is to perform reception or transmission on the access link using a first beam at a first time.

[0207] In some embodiments, the first information is used to indicate a first time, the first time being associated with the first signal.
