Description

[0001] This disclosure is a divisional application of Chinese application filed on June 28, 2022, with application number 202280002409.X and invention title "A relay communication method, apparatus, device and storage medium". Technical Field

[0002] This disclosure relates to the field of communication technology, and in particular to a relay communication method, apparatus, device and storage medium. Background Technology

[0003] Coverage is a fundamental aspect of cellular network deployment. Mobile operators rely on different types of network nodes to provide comprehensive coverage in their deployments, especially as carrier frequencies increase and radio signal loss in space becomes more significant. Deploying conventional full-stack units is one option, but it may not always be feasible.

[0004] 3GPP (3rd Generation Partnership Project) has considered using new network nodes, such as network-controlled repeaters (NCRs), to increase mobile operators' flexibility in network deployment. In high-frequency network deployments, beamforming technology is typically used to concentrate antenna energy in a specific area to improve the received signal strength of users and reduce interference to other users.

[0005] Therefore, how to achieve beam-based interference management and improve energy efficiency in NCR is an urgent problem to be solved. Summary of the Invention

[0072] The exemplary embodiments will be described in detail herein with reference to the attached drawings. The description of the exemplary embodiments is intended to apply to various alternative embodiments as well. It is to be understood that the description of some embodiments in the following is only intended to illustrate the possible implementation of the present embodiments and is not intended to be limiting of the scope of the present embodiments. On the contrary, the exemplary embodiments are intended to cover all alternatives, modifications and equivalents.

[0073] The terminology used in the present disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the present embodiments. As used in the description of the present embodiments and the appended claims, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that the term "and / or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

[0074] It should be understood that although the terms "first", "second", "third", etc. can be used herein to describe various information, the information should not be limited to these terms. These terms are only used to distinguish one piece of information from another. For example, "first information" can also be referred to as "second information", and similarly, "second information" can also be referred to as "first information", without departing from the scope of the present embodiments. Depending on the context, the word "if' as used herein can be interpreted as meaning "when" or "in response to" or "in the event that".

[0075] Further, in the description of the embodiments of the present disclosure, "and / or" only describes an association relationship for associated objects, and there can be three kinds of relationships. For example, A and / or B can mean that there are three cases of A alone, A and B together, and B alone. In addition, in the description of the embodiments of the present disclosure, "multiple" can mean two or more than two.

[0076] Coverage is a fundamental aspect of cellular network deployment. Mobile operators rely on deploying different types of network nodes to provide comprehensive coverage. Deploying regular full-stack units is one option, but it can not always be feasible (e.g., no backhaul) or economically feasible.

[0077] Therefore, it has been considered to employ new types of network nodes to increase the flexibility of mobile operators for their network deployment. For example, integrated access and backhaul (IAB) functionality was introduced in Rel-16 (Release 16) and enhanced in Rel-17 (Release 17) as a new type of network node that does not require a wired backhaul. Another type of network node is a radio frequency repeater, which is able to simply amplify and forward any received signal. Radio frequency repeaters have been widely deployed to complement the coverage provided by regular full-stack units.

[0078] While radio frequency repeaters provide an economically efficient method to extend network coverage, they also have their limitations. Radio frequency repeaters simply perform amplification and forwarding operations and do not take into account various factors that can improve performance, such as regarding semi-static and / or dynamic downlink / uplink configurations, adaptive transmitter / receiver spatial beamforming, on-off states, etc.

[0079] Therefore, enhancements to traditional radio frequency repeaters have resulted in network-controlled repeaters, i.e., NCRs. NCRs have the ability to receive and process side control information from the network. Side control information can allow the network to control the repeater to perform its amplification and forwarding operations in a more efficient manner. Potential benefits can include mitigating unnecessary noise amplification, transmission and reception with better spatial directionality, and simplified network integration.

[0080] Figure 1 A schematic diagram of a structure of an NCR of an embodiment of the present disclosure. As shown in FIG. 1, the NCR 100 includes a radio frequency repeater 110 and a network controller 120. The radio frequency repeater 110 is configured to receive a signal from a network node 130 and amplify and forward the signal to a user equipment (UE) 140. The network controller 120 is configured to receive and process side control information from a network node 150 and provide the side control information to the radio frequency repeater 110. Figure 1As shown, the NCR 100 can include an NCR-mobile termination (NCR-MT) module 110 and an NCR-forwarding (NCR-Fwd) module 120. The NCR-MT module 110 can establish a control link (C-link) with the network device 200. The NCR-Fwd module 120 can establish a backhaul link with the network device 200, and can establish an access link with the terminal device 300, thereby realizing the forwarding of uplink data and / or downlink data.

[0081] The control link is used to realize the transmission of control signaling between the NCR 100 and the network device 200, thereby controlling the backhaul link and the control link between the NCR 100 and the network device 200, and the access link between the NCR 100 and the terminal device 300.

[0082] In an embodiment, the terminal device 300 described above can be a terminal device with wireless communication function, which can also be referred to as a user equipment (UE). The terminal device can be deployed on land, including indoor or outdoor, handheld, wearable or vehicle-mounted; can also be deployed on water surface (such as ships, etc.); can also be deployed in the air (such as airplanes, balloons and satellites, etc.). The terminal device described above can be a mobile phone, a tablet computer (Pad), a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical treatment, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, etc. The terminal device can also be a handheld device, a vehicle-mounted device, a wearable device, a computing device or other processing device connected to a wireless modem with wireless communication function, etc. Optionally, the terminal device can also be called different names in different networks, such as terminal device, access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user device, cellular phone, cordless phone, session initiation protocol (SIP) phone, wireless local loop (WLL) station, personal digital assistant (PDA), terminal device in 5G network or future evolution network, etc.

[0083] The network device 200 described above can be an access network device, and further can be a device on the access network side for supporting terminal access to a wireless communication system. For example, it can be a next generation NodeB (gNB) in a 5G access technology communication system, a transmission reception point (TRP), a relay node, an access point (AP), etc.

[0084] In the embodiments of the present disclosure, the beams of the NCR 100 can include three parts: the beams of the first part are used for the control link, which can also be described as the beams at the NCR for the control link, the control link beams or the beams of the control link, etc.; the beams of the second part are used for the backhaul link, which can also be described as the beams at the NCR for the backhaul link, the backhaul link beams or the beams of the backhaul link, etc.; and the beams of the third part are used for the access link, which can also be described as the beams at the NCR for the backhaul link, the access link beams or the beams of the access link, etc.

[0085] It should be noted that, since the control link and the backhaul link are both links established between the NCR 100 and the network device 200, the control link and the backhaul link can multiplex (or share) one or more beams. Therefore, it can be understood that the control link beams and the backhaul link beams can be completely different beams, can be partially different beams, or can be completely the same beams, and the embodiments of the present disclosure do not make specific limitations on this.

[0086] In the embodiments of the present disclosure, the "beam" can be understood as one or more beams, or can be understood as one or more beam groups. Therefore, in this case, the "beam identification information" can be understood as the identification information of the beam, or can be understood as the identification information of the beam group.

[0087] In some possible implementation manners, the above-mentioned beams can be predefined in a communication protocol, or can be indicated by the network device 200. The network device 200 can indicate the beams by one or more of the beam identification information (beam ID / beam group ID) or the signal identification information (RS ID) of the reference signal (RS) associated with the beams.

[0088] However, in actual applications, the beams of the NCR can interfere with adjacent cells. In addition, since the transmission of each beam consumes a certain amount of energy, when the amount of data to be forwarded is small, continuing to transmit all beams will cause energy waste. Therefore, how to realize the beam management-based energy saving and interference management of the NCR is a problem to be solved urgently.

[0089] To solve the above problems, the embodiment of the disclosure provides a relay communication method. The method can be applied to a relay device, such as an NCR. Figure 2 A flowchart of a relay communication method according to an embodiment of the disclosure is shown in FIG. 2. As shown in FIG. 2, the method can include S201 and S202. Figure 2

[0090] S201, the relay device receives first indication information from a network device (such as a base station).

[0091] The first indication information is used to indicate the beam state of a first beam of the relay device.

[0092] It can be understood that the beam state of the first beam can refer to whether the first beam is activated. In an embodiment, the beams of the relay device can have two beam states: an activated state and a deactivated state. The activated state means that the beam can be used for transmission. The deactivated state means that the beam cannot be used for transmission. It should be noted that the activated state can refer to that the relay device transmits the beam, and the beam transmitted by the relay device is the beam that can be used for transmission. The deactivated state can refer to that the relay device does not transmit the beam, and the beam not transmitted by the relay device is the beam that cannot be used for transmission. Therefore, the two states of the beam can be expressed in other ways. For example, the activated state can also be referred to as the on state or the enabled state, and the deactivated state can also be referred to as the off state or the disabled state.

[0093] In an embodiment, the first beam can include at least one of the following: one or more beams and / or beam groups of a backhaul link; one or more beams and / or beam groups of a control link; and one or more beams and / or beam groups of an access link.

[0094] In an embodiment, the first indication information can include a beam identifier of the first beam and / or a target state of the first beam. The beam identifier is used to identify the first beam. The target state is a state indicated by the network device for the relay device to set the first beam to. For example, if the target state is the activated state, it means that the beam state represented by the first indication information is the activated state; if the target state is the deactivated state, it means that the beam state represented by the first indication information is the deactivated state.

[0095] ​In some possible implementation, the first indication information can be used to indicate to set the beam state. In an implementation, the first indication information can comprise a beam identity. In this case, the target state can be (implicitly) a second state different from the first state. The first state can be a current state of the first beam. The first state is one of the active state and the inactive state, and the second state is the other one of the active state and the inactive state.

[0096] In some possible implementation, the first indication information can be used to indicate to set the beam state to a third state. In an implementation, the first indication information can comprise a beam identity and a target state. The target state can be the third state. The third state can be either one of the active state and the inactive state. In an implementation, the first indication information can comprise the target state. In this case, the first beam can be all beams and / or beam groups of a backhaul link and / or a control link and / or an access link of the relay device.

[0097] It can be understood that, in the disclosed embodiments, the operations of “determining”, “setting”, “configuring”, “changing”, “modifying” and the like can be regarded as operations of the same type or similar type if necessary.

[0098] It should be noted that, in the present embodiment, the first indication information can be carried on the DCI.

[0099] In another embodiment, the first indication information can be used to indicate an activation configuration of the first beam. In this case, the first beam can be associated with the activation configuration information. The activation configuration information can be used to indicate the beam state of the first beam in at least one time unit. The first indication information can comprise the activation configuration information. Here, the time unit can be a frame, a sub-frame, a slot, a sub-slot, a symbol, etc.

[0100] In some possible implementation, the activation configuration information can comprise one of the following: a pattern, a validity time of the pattern, a validity duration of the pattern. The pattern is a configuration of the activation / inactivation of the first beam. The validity time of the pattern is a time at which the beam state of the first beam starts to be configured by the pattern. The validity duration of the pattern is a duration during which the pattern is applied to the first beam.

[0101] In actual application, the pattern can be represented in binary form. For example, the pattern can be “1110001”, wherein “0” and “1” can represent the inactivation state and the activation state respectively. In this case, the pattern “1110001” represents that the beam state of the first beam in the consecutive seven time units is in turn: active, active, active, inactivation, inactivation, inactivation, active.

[0102] In actual application, the pattern can also be expressed in a manner of duration of the state. For example, the pattern can be expressed according to the number of activated time units and / or the number of deactivated time units. In this case, the pattern can include a plurality of time units in the duration of the pattern, wherein the beam is in the activated state in one or more time units in front, and / or the beam is in the non-activated state in one or more time units in back.

[0103] In some possible implementation manners, the pattern can be applied only once or repeatedly when applied to the first beam. Therefore, the effective duration of the pattern can be included in the first indication information. The effective duration can be expressed in time, number of repetitions or other manners. In an example, the effective duration can be expressed by the application time of the pattern. For example, the effective duration can be expressed by the number of time units, or can be expressed by the time length. In another example, the effective duration can be expressed by the number of applications of the pattern.

[0104] It should be noted that in this embodiment, the first indication information can be carried on the RRC signaling.

[0105] In addition, it can be understood that the first beam can be associated with a plurality of activation configuration information. Each activation configuration information can be used to indicate the beam state of the first beam in at least one time unit. The first indication information is used to indicate one or more first activation configuration information in the plurality of activation configuration information. For example, the first indication information can include the one or more first activation configuration information, or the first indication information can include the identification of the one or more first activation configuration information.

[0106] It should be noted that in this embodiment, the first indication information can be carried on the MAC CE or the DCI.

[0107] S202, the relay device determines the beam state of the first beam according to the first indication information.

[0108] Wherein, after receiving the first indication information in S201, the relay device sets the beam state of the first beam according to the first indication information.

[0109] In an embodiment, the relay device can set the beam state of the first beam according to the first indication information in the following manner.

[0110] In an implementation manner, the first indication information can be used to indicate to set the beam state, and then S202 can be specifically: the relay device sets the beam state of the first beam from the first state to the second state according to the first indication information.

[0111] In an embodiment, the first indication information can be used to indicate that the beam state is set to the third state, and S202 can be specifically: setting, by the relay device according to the first indication information, the beam state of the first beam to the third state.

[0112] In an embodiment, there can be a delay between receiving the first indication information from the relay device and completing, by the relay device, the setting of the beam state of the first beam. In actual application, the delay can be determined based on the transmission performance between the relay device and the network device, the device parameters of the relay device, and other parameters.

[0113] In an embodiment, the relay device can determine that the receiving of the first indication information reaches a second duration. That is, after receiving the first indication information, the relay device times the second duration. When the timing reaches the second duration, the relay device completes S202. In other words, when the timing reaches the second duration, the beam state indicated by the first indication information takes effect on the first beam.

[0114] In an embodiment, the relay device can further include: sending, by the relay device to the network device, an acknowledgement information for the first indication information. The acknowledgement information is used to acknowledge the first indication information to the network device. In this case, the relay device can determine that the sending of the acknowledgement information reaches a third duration. That is, after sending the acknowledgement information, the relay device times the third duration. When the timing reaches the third duration, the relay device completes S202. In other words, when the timing reaches the third duration, the beam state indicated by the first indication information takes effect on the first beam.

[0115] In some possible embodiments, the second duration and the third duration can be independent of each other. In general cases, the relay device can only consider the second duration or the third duration. However, it can be understood that the relay device can consider the second duration and the third duration in combination. For example, the relay device can complete S202 when both the second duration and the third duration reach. For another example, the relay device can complete S202 when one of the second duration and the third duration reaches.

[0116] In an embodiment, in the case that the beam state of the first beam is the non-activated state, the method can further include: determining, by the relay device, that the first beam is not included in the beam indication information transmitted by the network device; or determining, by the relay device, that the first beam is not included in the beam indication information transmitted by the network device within the first time length. As described above, the beam state of each beam of the relay device is known to the network device. Therefore, in the case that the beam state of the first beam is the non-activated state, the relay device can determine that the network device does not use the first beam for transmission, i.e., the first beam is not included in the beam indication information indicating the beam used for transmission. Alternatively, in the case that the beam state of the first beam is the non-activated state, the relay device can determine that the network device does not use the first beam for transmission within the first time length, i.e., the first beam is not included in the beam indication information indicating the beam used for transmission.

[0117] In another embodiment, the relay device can set the beam state of the first beam according to the first indication information in the following manner.

[0118] In an implementation, the first indication information can be used to indicate the activated configuration of the first beam, and the first beam is associated with the activated configuration information. The relay device can set the beam state of the first beam according to the first indication information. For example, in the case that the first indication information includes a pattern, the relay device can set the beam state of the first beam according to the pattern. For another example, in the case that the first indication information includes a pattern and a valid time, the relay device can set the beam state of the first beam according to the pattern starting from the valid time. For another example, in the case that the first indication information includes a pattern and a valid time length, the relay device can set the beam state of the first beam to follow the pattern within the valid time length. For another example, in the case that the first indication information includes a pattern, a valid time and a valid time length, the relay device can set the beam state of the first beam to follow the pattern within the valid time length starting from the valid time.

[0119] In an implementation, the first indication information can be used to indicate the activated configuration of the first beam, and the first beam is associated with a plurality of activated configuration information. The relay device can set the beam state of the first beam according to the first indication information. For example, in the case that the first indication information includes an identifier of the first activated configuration information, the relay device can determine the first activated configuration information corresponding to the identifier from the plurality of activated configuration information of the first beam, and use the first activated configuration information to set the beam state of the first beam.

[0120] In addition, in actual applications, the beams of the relay device usually have initial beam states. In an embodiment, the method can further include: setting, by the relay device, the initial beam state of the first beam to the activated state or the non-activated state. It can be understood that the initial beam state of the first beam can be a default setting, i.e., directly set by the relay device when powered on.

[0121] In addition, the disclosure also provides a relay communication method. The method can be applied to a network device. Figure 3 A flowchart of the relay communication method of the embodiments of the disclosure is shown in FIG. 3. As shown in the figure, the method can include S301 and S302. Figure 3 S301, the network device determines the beam state of the first beam of the relay device.

[0122] S301, the network device determines the beam state of the first beam of the relay device.

[0123] The network device first needs to determine how to set the beam state of the first beam.

[0124] It can be understood that the network device can determine the beam state of the first beam according to one or more of the following information: the data volume of the backhaul link of the relay device, the quality parameter of the backhaul link, the data volume of the access link of the relay device, the quality parameter of the access link, etc. These information can be fed back to the network device by the relay device. Of course, the data volume of the backhaul link and the data volume of the access link can be equal sometimes, and the network device can directly obtain the data volume of the backhaul link. In this case, the relay device can only feed back the quality parameter to the network device. It should be noted that the network device can also determine the beam state of the first beam according to other information, which is not limited in the embodiments of the disclosure.

[0125] In an embodiment, the beams of the relay device can have two states: an active state and an inactive state. The active state means that the beam can be used for transmission. The inactive state means that the beam cannot be used for transmission. It should be noted that the active state can mean that the relay device transmits the beam, and the beam transmitted by the relay device is the beam that can be used for transmission. The inactive state can mean that the relay device does not transmit the beam, and the beam not transmitted by the relay device is the beam that cannot be used for transmission. Therefore, the two states of the beam can be expressed in other ways. For example, the active state can also be called an on state or an enabled state, and the inactive state can also be called an off state or a disabled state.

[0126] It should be noted that the beam state of the beam of the relay device is known to the network device. Specifically, when the network device determines the beam state of the first beam, the network device can know the current beam state of each beam of the relay device.

[0127] In an embodiment, the initial beam state of the first beam of the relay device can be the active state or the inactive state. And the initial beam state of the first beam can be known to the network device. For example, the network device can default to consider that the initial beam state of the first beam of the relay device is the active state.

[0128] In an embodiment, the network device does not include the first beam in the beam indication information sent by the network device in a case that the beam state of the first beam is the non-active state; or, the network device does not include the first beam in the beam indication information sent by the network device in the first time length.

[0129] S302, the network device sends first indication information to the relay device.

[0130] The first indication information is used to indicate the beam state of the first beam.

[0131] In an embodiment, the first beam of the relay device associated with the first indication information can include at least one of the following: one or more beams and / or beam groups of the backhaul link; one or more beams and / or beam groups of the control link; one or more beams and / or beam groups of the access link.

[0132] In an embodiment, the first indication information can include a beam identifier of the first beam and / or a target state of the first beam. The beam identifier is used to identify the first beam. The target state is a state indicated by the network device to the relay device to set the first beam to.

[0133] In some possible implementation manners, the first indication information can be used to indicate to set the beam state. In an implementation manner, the first indication information can include a beam identifier. In this case, the target state can be (implicitly) a second state different from a first state. The first state can be a current state of the first beam. The first state is one of the active state and the non-active state, and the second state is the other state of the active state and the non-active state.

[0134] In some possible implementation manners, the first indication information can be used to indicate to set the beam state to a third state. In an implementation manner, the first indication information can include a beam identifier and a target state. The target state can be the third state. The third state can be the active state or the non-active state. In an implementation manner, the first indication information can include the target state. In this case, the first beam can be all beams and / or beam groups of the backhaul link and / or the control link and / or the access link of the relay device.

[0135] It should be noted that in the present embodiment, the first indication information can be carried on the DCI. In this case, S302 can include: the network device sends a physical downlink control channel (PDCCH) to the relay device. The DCI is carried on the PDCCH.

[0136] In another embodiment, the first indication information can be used to indicate an activation configuration of the first beam. In this case, the first beam can be associated with the activation configuration information. The activation configuration information can be used to indicate a beam state of the first beam over at least one time unit. The first indication information can comprise the activation configuration information. Here, the time unit can be a frame, a subframe, a slot, a sub-slot, a symbol, etc.

[0137] In some possible implementation, the activation configuration information can comprise one of the following: a pattern, a valid time of the pattern, a valid duration of the pattern. The pattern is a configuration of activation / deactivation of the first beam. The valid time of the pattern is a time at which the beam state of the first beam starts to be configured by the pattern. The valid duration of the pattern is a duration during which the pattern is applied to the first beam.

[0138] In actual application, the pattern can be represented in binary form. For example, the pattern can be “1110001”, where “0” and “1” can represent the deactivation state and the activation state respectively. In this case, the pattern “1110001” indicates that the beam state of the first beam over the consecutive seven time units is: activation, activation, activation, deactivation, deactivation, deactivation, activation.

[0139] In some possible implementation, the pattern can be applied only once or repeatedly when applied to the first beam. Therefore, the valid duration of the pattern can be included in the first indication information. The valid duration can be represented by time, number of repetitions or other ways. In an example, the valid duration can be represented by the application time of the pattern. For example, the valid duration can be represented by the number of time units, or can be represented by the duration. In another example, the valid duration can be represented by the number of applications of the pattern.

[0140] It should be noted that in the present embodiment, the first indication information can be carried on the RRC signaling. In this case, S302 can comprise that the network device sends the RRC signaling to the relay device.

[0141] In addition, it can be understood that the first beam can be associated with multiple activation configuration information. Each activation configuration information can be used to indicate a beam state of the first beam over at least one time unit. The first indication information is used to indicate one or more first activation configuration information in the multiple activation configuration information. For example, the first indication information can comprise the one or more first activation configuration information, or the first indication information can comprise an identification of the one or more first activation configuration information.

[0142] It should be noted that in this embodiment, the first indication information can be carried on a MAC CE or a DCI. For example, in the case of a MAC CE, S302 can include that the network device sends a MAC CE to the relay device. For another example, in the case of a DCI, S302 can include that the network device sends a PDCCH to the relay device. The DCI is carried on the PDCCH.

[0144] In the embodiments of the present disclosure, the network device can send the first indication information for indicating the beam state to the relay device, so that the relay device can set the beam state of the corresponding beam according to the first indication information. In this way, the network device can control the beam state of the relay device. Specifically, the present disclosure uses the active / deactive state or the active / deactive pattern for explicit indication of the beam state, so that the active / deactive of the beam of the relay device can be efficiently controlled, the power consumption of the relay device is reduced, and the energy efficiency is improved; and the interference of the relay device to the adjacent cell is reduced, and the beam-based interference management is implemented.
