[0044] In the following, in combination with the accompanying drawings, a forwarding processing method, apparatus and relay device provided in an embodiment of the present application are described in detail through some embodiments and their application scenarios.

[0045] See also Figure 3 , Figure 3 is a flow chart of a forwarding processing method provided by an embodiment of the present application, such as Figure 3 As shown, the following steps are included:

[0046] Step 301: When there is a duplex conflict between a first carrier and a second carrier, the relay device performs forwarding on the first carrier according to a priority forwarding strategy;

[0047] Wherein, in the priority forwarding strategy, the first carrier takes precedence over the second carrier.

[0048] The first carrier may be an Fwd carrier, and the second carrier may be an Fwd carrier. In some implementations, the first carrier may be one or more carriers, and the second carrier may be one or more carriers.

[0049] The duplex conflict may be a time division duplex (TDD) conflict, such as a TDD conflict between the first carrier and the second carrier at the same time. In some implementations, the duplex conflict may also be a frequency division duplex (FDD) conflict.

[0050] In some embodiments, the presence of a duplex conflict between the first carrier and the second carrier may include that the forwarding direction of the first carrier is different from the forwarding direction of the second carrier on the same time domain resource, for example: in some symbols, the forwarding directions of the first carrier and the second carrier are uplink and downlink, respectively, that is, the Fwd of the relay device needs to forward the uplink (Up Link, UL) and the downlink (Down Link, DL) at the same time, but the Fwd of the relay device does not have the ability to forward DL and UL at the same time.

[0051] The above priority forwarding strategy may be agreed upon by the protocol or configured on the network side.

[0052] The above-mentioned priority forwarding strategy is used to determine a carrier for priority forwarding among multiple carriers.

[0053] The above-mentioned forwarding on the first carrier refers to that the relay device forwards the communication content on the first carrier, and forwards the UL or DL ​​communication content.

[0054] In the embodiment of the present application, the communication content on the carrier includes at least one of the following:

[0055] Message, signal, channel, data.

[0056] In an embodiment of the present application, the above steps can be used to achieve that when there is a duplex conflict between the first carrier and the second carrier, the relay device performs forwarding on the first carrier, thereby avoiding the situation where the relay device is unable to forward in the case of the duplex conflict, thereby improving the communication performance of the relay device.

[0057] As an optional implementation manner, the priority forwarding strategy includes at least one of the following:

[0058] Prioritize the forwarding of carriers with higher priority;

[0059] Prioritize forwarding of carriers that do not require uplink or downlink switching;

[0060] Forwarding of carriers corresponding to priority cell-specific signals;

[0061] Prioritize forwarding of reference carriers;

[0062] Determine a carrier for priority forwarding based on a beam indication of the carrier;

[0063] The priority duplex configuration is forwarding of a carrier configured by cell-specific signaling, or the priority duplex configuration is forwarding of a carrier configured by terminal-specific signaling.

[0064] The first carrier is a carrier for priority forwarding determined based on a priority forwarding strategy.

[0065] The forwarding of the carrier with higher priority refers to the forwarding of the communication content on the carrier with higher priority first, that is, the priority of the first carrier is higher than that of the second carrier, so as to ensure the forwarding of the carrier with higher priority first, so as to improve the service performance of the relay equipment.

[0066] In some implementations, the priorities of the first carrier and the second carrier are priorities configured by the network side. For example, if the network side device configures the forwarding priorities of multiple carriers, when there is a forwarding demand in the opposite uplink and downlink directions, the communication content of the carrier with the higher priority is forwarded first.

[0067] The above-mentioned priority forwarding of carriers that do not require uplink and downlink switching refers to giving priority to forwarding the communication content of carriers that do not require uplink and downlink switching, wherein the carrier that does not require uplink and downlink switching means that the corresponding uplink and downlink switching of the carrier does not need to be performed during or before forwarding. For example: if the forwarding of a certain carrier does not require uplink and downlink switching, the forwarding on this carrier is given priority. If the carrier previously performed uplink forwarding, and there is an uplink forwarding demand for this carrier and a downlink forwarding demand for other carriers immediately afterwards, the carrier that performs uplink forwarding is given priority for forwarding.

[0068] By giving priority to forwarding the carriers that do not need to be switched up or down, the relay device can be prevented from performing frequent up or down switching, thereby saving power consumption of the relay device.

[0069] Prioritizing the forwarding of a carrier corresponding to a cell-specific signal means giving priority to forwarding the signal of the carrier corresponding to the cell-specific signal, wherein the carrier corresponding to the cell-specific signal may refer to the carrier on which the cell-specific signal exists. For example, if there is forwarding of a cell-specific signal on a certain carrier at the time of duplex conflict, the cell-specific signal is forwarded first.

[0070] In some implementations, the cell-specific signal may include at least one of the following:

[0071] Synchronization Signal Block (SSB), Physical Random Access Channel (PRACH).

[0072] By forwarding the carrier corresponding to the priority cell-dedicated signal, the priority cell-dedicated signal can be forwarded, thereby preferentially ensuring the transmission of the cell-dedicated signal to improve the transmission reliability of the cell-dedicated signal.

[0073] The above-mentioned priority forwarding of the reference carrier (reference CC) refers to the priority forwarding of the communication content of the reference carrier. The reference carrier may be agreed upon by the protocol or configured by the network side.

[0074] By giving priority to forwarding the reference carrier, the communication content on the reference carrier can be forwarded, so as to improve the transmission performance of the relay device on the reference carrier.

[0075] In some implementations, the reference carrier includes at least one of the following:

[0076] A carrier whose carrier number meets a preset condition among the carriers corresponding to the relay device;

[0077] Control link (C-link) carrier;

[0078] There is a carrier overlapped with the carrier of the control link;

[0079] Reference carrier indicated by the network side.

[0080] The carriers whose carrier numbers meet the preset conditions may include:

[0081] The carrier with the lowest carrier number among the carriers corresponding to the relay device;

[0082] The carrier number of the carrier corresponding to the relay device is a carrier with a preset number.

[0083] The carriers corresponding to the relay device may be all carriers in a frequency band.

[0084] The carrier of the control link may be a carrier belonging to the control link, such as a serving cell of the control link. Alternatively, the carrier of the control link may be a carrier where an active bandwidth part (active BWP) of the control link is located, such as an Fwd carrier where the active BWP of the control link is located.

[0085] The carrier overlapping with the carrier of the control link may be a carrier partially or completely overlapping with the carrier of the control link. Alternatively, the carrier overlapping with the carrier of the control link may be a carrier overlapping with the carrier where the active BWP of the control link is located.

[0086] The reference carrier indicated by the network side is a reference carrier indicated by a network side device.

[0087] The above-mentioned carrier for priority forwarding determined based on the beam indication of the carrier refers to the carrier for priority forwarding determined based on the beam indication of the carrier. For example, the beam indication of a carrier carries a priority identifier, thereby giving priority to the forwarding of the carrier corresponding to the beam indication carrying the priority identifier. For example, the beam indication of a carrier is used to indicate the forwarding beam of a cell-dedicated signal, thereby giving priority to the forwarding of this carrier.

[0088] Determining the carrier for priority forwarding based on the beam indication of the carrier can enable the relay device to handle duplex conflicts based on the beam indication of the carrier without introducing additional messages or configurations, thereby reducing the complexity of the relay device in handling duplex conflicts.

[0089] The duplex configuration of the carrier may indicate a duplex forwarding configuration of the carrier, such as duplex-related configurations such as resources, mode or power. In some implementations, the duplex configuration is a TDD configuration.

[0090] The above-mentioned priority duplex configuration forwarding of the carrier configured by cell-specific signaling means that the communication content of the carrier configured by cell-specific signaling is forwarded preferentially. For example: if at the time of duplex conflict, the TDD of one carrier is configured by cell-specific signaling, and the TDD of another carrier is configured by UE-specific signaling, the TDD configured by cell-specific signaling is forwarded preferentially; or vice versa (depending on the control strategy of the base station for uplink and downlink interference).

[0091] The above-mentioned priority forwarding of the carrier whose duplex configuration is configured as terminal-specific signaling (UE-specific signaling) means giving priority to forwarding the communication content of the carrier whose duplex configuration is configured as terminal-specific signaling. For example, if at the time of duplex conflict, the TDD of one carrier is configured by cell-specific signaling and the TDD of another carrier is configured by UE-specific signaling, forwarding is given priority according to the TDD configured by UE-specific signaling.

[0092] Among them, the forwarding of the carrier configured with priority duplex configuration as the cell-specific signaling or the forwarding of the carrier configured with priority duplex configuration as the terminal-specific signaling may depend on the control strategy of the network-side device for the uplink and downlink interference.

[0093] Optionally, the determining of the carrier for priority forwarding based on the beam indication of the carrier includes at least one of the following:

[0094] Prioritize the forwarding of carriers with periodic beam indications;

[0095] In the case where the carriers where the duplex conflict occurs include a carrier with a non-periodic beam indication and also include a carrier with a periodic beam indication, the carrier with the non-periodic beam indication is forwarded preferentially;

[0096] In the case where the carriers where the duplex conflict occurs include a carrier with a semi-persistent beam indication and also include a carrier with a periodic beam indication, the carrier with the semi-persistent beam indication is given priority in forwarding;

[0097] When the carriers where duplex conflict occurs include a carrier with a non-periodic beam indication and also include a carrier with a semi-persistent beam indication, the carrier with the non-periodic beam indication is forwarded preferentially.

[0098] Among them, the above-mentioned beam indication can be an access link (Access link, AL) beam indication, that is, a periodic (AL) beam indication, and specifically can be a UL beam indication or a DL beam indication.

[0099] The above-mentioned priority forwarding of the carrier with periodic beam indication means that the beam indications of other carriers are not considered, and the communication content of the carrier with periodic beam indication is directly and preferentially forwarded, because the communication content of the carrier with periodic beam indication is generally more important, thereby realizing the forwarding of important communication content. For example: if there is a periodic beam indication on a carrier at the time of duplex conflict, the communication content on this carrier is forwarded preferentially. In some embodiments, the periodic beam indication carries a priority identifier, because the periodic beam indication with a priority identifier can generally be used to indicate the forwarding beam of the cell-specific signal.

[0100] In some implementations, the above-mentioned forwarding of the carrier with the non-periodic beam indication having priority may be that when the periodic beam indication does not carry a priority identifier, the carrier with the non-periodic beam indication having priority is forwarded.

[0101] In some embodiments, the forwarding of the carrier with the semi-persistent beam indication having priority may be the forwarding of the carrier with the semi-persistent beam indication having priority when the periodic beam indication does not carry a priority identifier.

[0102] In the above implementation, the carrier with duplex conflict can be forwarded flexibly. Specifically, the first carrier can be determined based on the priority of the beam indication, that is, the carrier to be forwarded first can be determined.

[0103] For example, if at the time of duplex conflict, if there is a non-periodic beam indication on one carrier and a periodic (AL) beam indication on another carrier (such as an Fwd carrier), the signal on the carrier with the non-periodic (AL) beam indication (such as the Fwd carrier) is forwarded first. Optionally, the periodic (AL) beam indication does not carry a priority indicator.

[0104] Alternatively, if at the time of duplex conflict, if there is a semi-persistent (AL) beam indication on one carrier and a periodic (AL) beam indication on another carrier (such as an Fwd carrier), the signal forwarding on the carrier (such as the Fwd carrier) with the semi-persistent (AL) beam indication is prioritized. Optionally, the periodic (AL) beam indication does not carry a priority identifier.

[0105] Alternatively, if at the time of duplex conflict, if there is a non-periodic (AL) beam indication on one carrier (such as an Fwd carrier) and a semi-persistent (AL) beam indication on another carrier, the signal on the carrier with the non-periodic (AL) beam indication (such as the Fwd carrier) is forwarded preferentially. Optionally, the semi-persistent (AL) beam indication does not carry a priority identifier.

[0106] As an optional implementation, the method further includes:

[0107] The relay device turns off forwarding of the second carrier; or

[0108] The relay device sets the forwarding direction of the second carrier to the forwarding direction of the first carrier.

[0109] The relay device turning off the forwarding of the second carrier may turn off the forwarding function corresponding to the second carrier, that is, at the moment of duplex conflict, the relay device turns off the forwarding function of the non-priority forwarding carrier to save power consumption of the relay device.

[0110] The above forwarding direction includes an uplink forwarding direction or a downlink forwarding direction.

[0111] The above-mentioned relay device sets the forwarding direction of the second carrier to the forwarding direction of the first carrier so that the DL / UL forwarding direction of the relay device on the non-priority forwarding carrier is equal to the DL / UL direction on the priority forwarding carrier, thereby enabling the relay device to forward the communication content on both carriers.

[0112] As an optional implementation, the method further includes:

[0113] When the carrier corresponding to the MT of the relay device overlaps or is associated with the target carrier, the relay device performs target processing on the target carrier according to the forwarding direction of the target carrier and the signal direction of the carrier corresponding to the MT;

[0114] Wherein, the target processing includes:

[0115] Perform forwarding on the target carrier, or turn off forwarding of the target carrier, or set the forwarding direction of the target carrier to the signal direction of the carrier corresponding to the MT.

[0116] The target carrier may be the first carrier or the second carrier.

[0117] The step of performing target processing on the target carrier may be performed before step 301 , or after step 301 , or simultaneously with step 301 .

[0118] The overlap between the carrier corresponding to the MT of the relay device and the target carrier may be that the carrier corresponding to the MT of the relay device and the target carrier overlap partially or completely.

[0119] The association between the carrier corresponding to the MT of the relay device and the target carrier may be that there is a preset association relationship between the carrier corresponding to the MT of the relay device and the target carrier, and the preset association relationship is a protocol agreement or a network side device.

[0120] The carrier corresponding to the MT is a carrier received or sent by the MT, and the signal direction of the carrier corresponding to the MT is a direction in which the MT receives or sends on the carrier, such as uplink or downlink.

[0121] The above-mentioned relay device performs target processing on the target carrier according to the forwarding direction of the target carrier and the signal direction of the carrier corresponding to the MT. The relay device may perform forwarding on the target carrier or shut down the forwarding of the target carrier according to whether the forwarding direction of the target carrier and the signal direction of the carrier corresponding to the MT are the same.

[0122] The target processing of the target carrier is performed at the moment when the MT of the relay device receives or sends a signal. That is, when the target carrier is subjected to the target processing, the MT of the relay device receives or sends a signal, so that the transmission of the MT can be guaranteed.

[0123] The execution of the forwarding on the target carrier may be that the MT receives or sends a signal and forwards the signal on the target carrier simultaneously.

[0124] The above-mentioned disabling of forwarding of the target carrier may be disabling a forwarding function corresponding to the target carrier.

[0125] The forwarding direction of the target carrier is set to the signal direction of the carrier corresponding to the MT so that the DL / UL forwarding direction of the relay device on the target carrier is equal to the signal direction of the carrier corresponding to the MT, so that the MT of the relay device can receive or send signals and forward the communication content on the target carrier.

[0126] In this implementation, since the relay device performs target processing on the target carrier according to the forwarding direction of the target carrier and the signal direction of the carrier corresponding to the MT, this can improve the communication performance of the relay device and can also avoid the relay device from frequently performing uplink and downlink switching to save power consumption of the relay device.

[0127] Optionally, the relay device performs target processing on the target carrier according to the forwarding direction of the target carrier and the signal direction of the carrier corresponding to the MT, including:

[0128] In a case where the signal of the carrier corresponding to the MT is a specific signal, the relay device performs target processing on the target carrier according to the forwarding direction of the target carrier and the signal direction of the carrier corresponding to the MT.

[0129] The above-mentioned specific signal is a signal agreed upon by the protocol or configured by the network side, such as SSB, PRACH or Scheduling Request (SR) signal. For example, when the MT receives SSB or sends PRACH / SR signal, the target carrier is subjected to target processing.

[0130] In this implementation, since the signal of the carrier corresponding to the MT is a specific signal, the relay device performs target processing on the target carrier according to the forwarding direction of the target carrier and the signal direction of the carrier corresponding to the MT, which can improve the specific signal receiving and sending performance of the MT, that is, in this case, the specific signal receiving and sending performance of the MT is prioritized.

[0131] It should be noted that in some implementations, the above-mentioned specific signals may not be considered. For example, under any transmission of the MT, the relay device performs target processing on the target carrier according to the forwarding direction of the target carrier and the signal direction of the carrier corresponding to the MT.

[0132] Optionally, the relay device performs target processing on the target carrier according to the forwarding direction of the target carrier and the signal direction of the carrier corresponding to the MT, including at least one of the following:

[0133] When the forwarding direction of the target carrier is the same as the signal direction of the carrier corresponding to the MT, forwarding on the target carrier is performed;

[0134] When the forwarding direction of the target carrier conflicts with the signal direction of the carrier corresponding to the MT, the forwarding of the target carrier is turned off.

[0135] The above-mentioned forwarding on the target carrier is forwarding according to the duplex configuration of the carrier. For example, the DL / UL forwarding direction of the target carrier (such as the Fwd carrier) is consistent with the receive / transmit (DL / UL) direction of the MT, and the relay device forwards the communication content on the carrier according to the TDD configuration of the carrier.

[0136] The conflict between the forwarding direction of the target carrier and the signal direction of the carrier corresponding to the MT may mean that the forwarding direction of the target carrier and the signal direction of the carrier corresponding to the MT are opposite, such as the forwarding direction of the target carrier is uplink and the signal direction of the carrier corresponding to the MT is downlink, or the forwarding direction of the target carrier is downlink and the signal direction of the carrier corresponding to the MT is uplink.

[0137] In this implementation, since the forwarding direction of the target carrier is the same as the signal direction of the carrier corresponding to the MT, forwarding on the target carrier is performed, so that the transmission performance of the target carrier and the MT can be guaranteed. Since the forwarding direction of the target carrier conflicts with the signal direction of the carrier corresponding to the MT, the forwarding of the target carrier is turned off, so that the transmission performance of the MT is guaranteed while avoiding the relay device from frequently performing uplink and downlink switching, so as to save the power consumption of the relay device. Since the forwarding direction of the target carrier conflicts with the signal direction of the carrier corresponding to the MT, the forwarding direction of the target carrier is set to the signal direction of the carrier corresponding to the MT, so that in the case of this conflict, the MT of the relay device receives or sends a signal and can also forward the communication content on the target carrier, so as to improve the communication performance of the relay device.

[0138] As an optional implementation, the method further includes:

[0139] The relay device reports the duplex capability information to the network side device.

[0140] The above duplex capability information may be TDD capability information or FDD capability information.

[0141] In some implementations, the duplex capability information includes at least one of the following:

[0142] The relay device supports carriers that are forwarded simultaneously in downlink and uplink;

[0143] The relay device supports a frequency band for simultaneous forwarding of downlink and uplink;

[0144] The relay device does not support carriers that are forwarded simultaneously in downlink and uplink;

[0145] The relay device does not support the frequency band for simultaneous forwarding of downlink and uplink.

[0146] The carriers that the relay device supports simultaneous downlink and uplink forwarding refer to the carriers between which the relay device can perform DL and UL forwarding simultaneously.

[0147] The frequency bands that the relay device supports simultaneous downlink and uplink forwarding refer to the frequency bands in which the relay device can perform DL and UL forwarding simultaneously.

[0148] The carriers for which the relay device does not support simultaneous downlink and uplink forwarding refer to the carriers between which the relay device cannot perform DL and UL forwarding simultaneously.

[0149] The frequency bands in which the relay device does not support simultaneous downlink and uplink forwarding refer to that the relay device cannot perform DL and UL forwarding simultaneously between these frequency bands.

[0150] In this implementation, since the relay device reports the above-mentioned duplex capability information to the network side device, this enables the network side device to configure a communication configuration for the relay device that better matches the duplex capability of the relay device based on the duplex capability information. In this way, when the relay device communicates based on these communication configurations, interference between carriers or frequency bands can be reduced.

[0151] In the embodiment of the present application, when there is a duplex conflict between the first carrier and the second carrier, the relay device performs forwarding on the first carrier according to a priority forwarding strategy; wherein the first carrier takes precedence over the second carrier in the priority forwarding strategy. In this way, since the relay device performs forwarding on the first carrier when there is a duplex conflict between the first carrier and the second carrier, it is possible to avoid the situation where the relay device cannot forward in the case of the duplex conflict, thereby improving the communication performance of the relay device.
