Description

Method, equipment, device and storage medium for determining link transmission mode of repeater

Technical Field

The present disclosure relates to the field of wireless communications technologies, and in particular, to a method, an apparatus, a device, and a storage medium for determining a link transmission mode of a repeater.

Background

The repeater is a wireless signal relay product, and uses the repeater as one of the necessary means for realizing the goal of 'small capacity and large coverage', mainly because the repeater can ensure network coverage without increasing the number of base stations, and the manufacturing cost of the repeater is far lower than that of a micro-cellular system with the same effect. Repeater is a preferred solution to the extended coverage capability of a communication network. Compared with the base station, the system has the advantages of simple structure, less investment, convenient installation and the like, can be widely applied to dead areas and weak areas with poor network coverage, such as various places including markets, hotels, airports, wharfs, stations, stadiums, entertainment halls, subways, tunnels, highways, islands and the like, improves the communication quality, and solves the problems of call drop and the like.

The novel repeater is characterized in that a control plane protocol stack is added on the basis of the original repeater, a base station can control some functions of the repeater by sending network control information, and the characteristic that the base station performs network control on the repeater is supported in the R18 standard at present. Two links exist between the base station and the novel repeater, one is a Control link (C-link) and the other is a backhaul forwarding link (Forwarding Link For Backhaul, FLB). In the actual resource allocation process, the uplink C-link and FLB of the repeater may use a transmission mode of simultaneous transmission (also referred to as a transmission mode of frequency division multiplexing (Frequency Division Multiplexing, FDM) or a transmission mode of time division multiplexing (Time Division Multiplexing, TDM).

Different repeater can improve resource utilization rate by adopting the transmission mode of simultaneous transmission under the premise of ensuring communication quality due to different hardware parameter performances and different supporting capability of the transmission mode of simultaneous transmission, but the transmission mode is more suitable or only suitable for TDM transmission mode in some cases, interference and noise can be amplified if the transmission mode is still configured as the transmission mode of simultaneous transmission, and great waste of resources is caused, so that the link transmission mode suitable for the repeater needs to be determined. There is currently no method for determining the link transmission mode employed by the repeater.

Fig. 1 is one of flow diagrams of a method for determining a link transmission mode of a repeater provided in an embodiment of the present application, and referring to fig. 1, the embodiment of the present application provides a method for determining a link transmission mode of a repeater, which is applied to a repeater, and includes:

Step 101, reporting a transmission capability type of the repeater to a network device, wherein the transmission capability type is used for indicating the capability of the repeater to support a transmission mode of an uplink control link C-link and a backhaul forwarding link FLB;

102, receiving indication information sent by the network equipment; optionally, the indication information is determined by the network device according to a transmission capability type of the repeater;

and step 103, determining a link transmission mode of the repeater according to the indication information.

Specifically, fig. 2 is a schematic link structure diagram of a repeater provided in the embodiment of the present application, and referring to fig. 2, a link relationship exists among the base station, the repeater and the user equipment, where two links exist between the base station and the repeater, one is a control link (C-link), and the other is a backhaul Forwarding Link (FLB). A traffic forwarding link (Forwarding Link For Service, FLS) exists between the repeater and the user equipment. The uplink and the downlink of the C-link and the FLB exist, and the uplink C-link and the FLB of the repeater can be transmitted in a transmission mode of simultaneous transmission (also called FDM) or in a transmission mode of Time Division Multiplexing (TDM) in the actual resource allocation process.

The ability of the repeater to support the transmission modes of the C-link and the FLB, i.e., the ability of the repeater to transmit the uplink C-link and the FLB using the transmission mode of FDM or the transmission mode of TDM. When the transmission mode of FDM is adopted, the interference between the transmission signals of the uplink C-link and the FLB can be influenced by the frequency domain resource allocation of the C-link and the FLB. If the repeater can ensure that the uplink C-link and the FLB have no mutual interference or negligible interference influence, a sending mode of FDM (frequency division multiplexing) or a TDM (time division multiplexing) can be adopted; if the repeater considers that the interference exists between the uplink C-link and the FLB transmission signals, only a TDM transmission mode can be adopted. For the uplink, a TDM sending mode is adopted, so that the repeater only needs to forward signals at the moment of the FLB in different time by using the resources of the C-link and the FLB, and the interference between the C-link and the FLB can be effectively avoided; with the transmission mode of FDM, the repeater needs to forward all time signals since the FLB may be transmitted at any time. Since FLB can use all symbols when transmitting simultaneously, the resource utilization of the system is higher.

For different repeater stations, the supporting capability of the transmitting mode of the simultaneous transmission is different due to different performances of hardware parameters, the capability is required to be reported to the base station, and the base station determines which transmitting mode the repeater station adopts to transmit according to the capability of the repeater station. Considering those repeater stations capable of supporting the transmission mode of FDM, it is possible to operate normally even if it is not known whether the transmission mode configured by the base station at this time is TDM or FDM. However, if the base station can indicate whether the transmission mode of the repeater is TDM or FDM, the effects of suppressing interference and saving energy can be obtained. The specific principle is as follows: when the TDM transmission mode is adopted, the repeater station can not forward signals at the transmission moment of the C-link because the symbol of the C-link has no forward signals of the FLB, so that interference and noise are not amplified, and the energy-saving effect is also achieved.

According to the method for determining the link transmission mode of the repeater, the repeater reports the transmission capacity to the network equipment, and the network equipment informs the repeater of the link transmission mode to be adopted, so that the repeater supporting the simultaneous transmission capacity can improve the resource utilization rate when adopting the transmission mode of simultaneous transmission, and when adopting the TDM transmission mode, the repeater does not forward signals at the transmission moment of the C-link because the symbols or the time slots where the C-link is positioned do not have the forwarding signals of the FLB, and therefore the effects of saving energy and reducing interference can be achieved.

Specifically, a set of repeater transmission capability types may be preset or predefined by a high-level parameter configuration or system, and the repeater selects a transmission capability type from the set of repeater transmission capability types according to its own capability and reports the selected transmission capability type to the base station. The types of transmitting capabilities of the repeater may be classified according to different methods, for example, directly into the capability of supporting the transmission mode using FDM or the capability of supporting the transmission mode using TDM, or may be classified according to hardware parameters of the repeater. The base station side should have an adaptive configuration regardless of whether the repeater transmission capability type set is configured by a higher layer parameter or preset by the system. Therefore, through presetting the possible transmitting capability types of the repeater, the signaling consumption can be reduced, the resources can be saved, and the communication efficiency can be improved.

Specifically, different sets of repeater transmission capability types may be set according to different manners, and alternative set setting manners include, but are not limited to, the set setting manners listed below. A set comprising three transmission capability types may be provided, for example: { TDM, simultaneously, both TDM and simultaneously }, wherein TDM represents a transmission capability type of a link transmission mode supporting time division multiplexing TDM, simultaneousy represents a transmission capability type of a link transmission mode supporting simultaneous transmission, and both TDM and simultaneously represents a transmission capability type of a link transmission mode supporting TDM and simultaneous transmission.

A set comprising two transmission capability types may be provided, for example: { TDM, simultaneously }, wherein TDM represents a transmission capability type of a link transmission mode supporting TDM and simultaneousy represents a transmission capability type of a link transmission mode supporting TDM and simultaneous transmission.

A set comprising N transmission capability types, N being a positive integer, may be provided, for example: { gap1, gap2, … …, gapN }, wherein gap1-N respectively represent different frequency domain guard interval values, when the FDM transmission mode is adopted, interference between the uplink C-link and the FLB transmission signals can be influenced by the frequency domain resource allocation of the C-link and the FLB, when the interval between the two frequency domain resources is larger, the interference value is relatively smaller, and when the interval is smaller, the interference value is relatively larger. The frequency domain guard interval may be considered as an ability of the repeater to suppress interference between the transmission signals of the uplink C-link and FLB, even though the repeater considers an interval between frequency domain resources where interference does not exist between the transmission signals of the uplink C-link and FLB. The gap value is the number of Resource Blocks (RBs) or the bandwidth, and when the gap value is equal to the maximum number of RBs or the maximum working bandwidth of the repeater, the C-link and the FLB cannot be transmitted at the same time, and the repeater supports the TDM link transmission mode. In the case where the gap value is equal to zero, the bandwidth positions indicating the C-link and the FLB may be adjacent, and the repeater may transmit the C-link and the FLB at the same time.

Fig. 3 is one implementation schematic diagram for determining a link transmission mode of a repeater according to an embodiment of the present application, with reference to fig. 3, a horizontal axis is set to be a time domain, a vertical axis is set to be a frequency domain, a left side indicates a link transmission mode adopting simultaneous transmission (FDM), and a right side indicates a link transmission mode adopting TDM, and it can be seen that in the FDM link transmission mode, transmission signals of a C-link and an FLB may be transmitted in the same symbol or time slot, and bandwidth positions of the C-link and the FLB may be adjacent, or a certain interval may exist between frequency domain resources. In the TDM link transmission mode, the same symbol or slot only transmits C-link or FLB.

the type of transmission capability of the repeater is reported to the network device by means of higher layer parameters or a medium access Control Element (Media Access Control-Control Element, MAC-CE).

Specifically, the transmission capability type may be directly carried in a message, and the message may be sent to the base station, which may be referred to as explicit reporting, that is, directly reporting through the message. The MAC sublayer is mainly responsible for the reception of logical channels and transport channels and the scheduling of radio resources. This is similar to the implementation in 5G NR of a state dependent physical layer flow mechanism for the transmission configuration indication (Transmission Configuration Indicator, TCI) by higher layer signaling or by MAC CE messages, e.g. reporting the transmission capability type via an uplink physical shared channel (Physical Uplink Shared Channel, PUSCH) or a physical uplink control channel (Physical Uplink Control Channel, PUCCH) after completion of the random access procedure. The transmission capability type reported by explicit reporting may be any of the transmission capability types described in the above embodiments.

Specifically, in the random access process, different time-frequency resources or sequences for initiating initial access can be configured through higher-layer parameters to indicate the corresponding transmission capacity type, and when the repeater adopts the corresponding time-frequency resources or sequences for initial access, the base station can obtain the transmission capacity type supported by the repeater. This reporting may be referred to as implicit reporting, i.e. reporting indirectly through other parameters. The types of transmission capabilities that can be reported by implicit reporting and explicit reporting are similar or identical, i.e. the type of transmission capabilities reported by implicit reporting may be any of the types of transmission capabilities described in the above embodiments.

Random access opportunity RO frequency domain initial position;

random access opportunity RO time domain configuration;

root sequence index used by repeater.

Specifically, the repeater may indicate the corresponding transmission capability type through different random access resource parameters, and the random access resource parameters that may be selected include, but are not limited to, the parameters listed below, and the random access resource parameters that may be selected may be a combination of multiple parameters listed below:

corresponding random access occasion (Random Access Channel Occasion, RO) frequency domain starting position;

corresponding RO time domain configuration (prahconfigurationindex);

the root sequence index (prach-rootsequence index) used by the repeater.

Different repeater stations can adopt different random access resource parameter configurations, and then the corresponding relation between the random access resource parameter and the transmission capacity type is also different.

Specifically, the base station indicates the link transmission mode through higher Layer signaling or L1 signaling, for example, indicates the link transmission mode that the repeater should use through parameter configuration by using higher Layer signaling, or uses L1 signaling, that is, when the repeater is scheduled to transmit Layer 1 side control information (Layer 1-Side Control Information, L1-SCI) information to the repeater, one bit (bit) indication information is added to indicate the link transmission mode that the repeater should use. The L1 layer is the physical layer. This way, it may be referred to as explicit indication, i.e. directly by information. The repeater determines the link transmission mode according to the received link transmission mode indication information, for example, the link transmission mode indication information indicates that the TDM link transmission mode is adopted, so that the repeater does not forward on the symbol or the time slot where the C-link is positioned, and the other time forwards the received signal; the link transmission mode indication information indicates that the TDM link transmission mode is not adopted or indicates that the simultaneous link transmission mode is adopted, and then the repeater also forwards the symbol or the time slot where the C-link is located.

Specifically, a default link transmission mode may be preset through a higher-level parameter configuration or a system, and the default link transmission mode is adopted in the case that the indication of the link transmission mode by the base station is not detected. For example, the default link transmission mode may be set to be a TDM link transmission mode, and when no indication from the base station is detected, the repeater adopts the TDM link transmission mode, and when an indication from the base station is detected, the repeater determines to switch the link transmission mode according to the indication from the base station.

a TDM link transmission mode; or,

Specifically, a default link transmission mode may be set according to a hardware parameter of the repeater, for example, the default link transmission mode may be designated as TDM, or the default link transmission mode of the repeater with FDM capability may be designated as FDM, and the default link transmission mode of the repeater without FDM capability may be designated as TDM.

Specifically, the base station configures the C-link frequency domain resource occupation threshold value or the C-link frequency domain resource limitation area to indicate the link transmission mode through the high-layer signaling, and this mode may be referred to as implicit indication, that is, indication indirectly through other parameters. Referring to fig. 3, the threshold value of the C-link frequency domain resource occupation, that is, the threshold value of the resource occupied by the C-link in the vertical axis frequency domain, and if the resource occupied by the C-link exceeds the threshold value, there is interference between the C-link and the FLB. The C-link frequency domain resource restriction area is that the C-link restricts the occupied resource area on the vertical axis frequency domain, and if the C-link occupies the restriction area, the interference exists between the C-link and the FLB.

Specifically, on a symbol or a time slot where the C-link is located, setting the frequency domain resource occupation threshold value of the C-link as A, and when the frequency domain resource occupation ratio or bandwidth of the C-link is larger than the threshold value A, the base station cannot ensure that enough interval can be reserved between the bandwidths of the C-link and the FLB for avoiding interference because the occupation bandwidth of the C-link is larger at the moment, so that the repeater cannot send the FLB on the symbol or the time slot and can only forward the FLB in the TDM mode. When the frequency domain resource duty ratio or bandwidth of the C-link is smaller than the threshold value A, the base station can ensure that enough interval can be reserved between the bandwidths of the C-link and the FLB for avoiding interference because the occupied bandwidth of the C-link is smaller, and the repeater can send the FLB on the symbol or the time slot, namely the FLB forwarding in the FDM mode can be performed.

Specifically, the C-link frequency domain resource occupation threshold is related to a frequency domain guard interval value (gap value) reported by the repeater, and gaps 1-N respectively represent different frequency domain guard interval values.

Specifically, the base station may calculate the C-link frequency domain resource occupation threshold according to the gap value, that is, the frequency domain guard interval value, where the calculation modes include, but are not limited to, the following modes:

A＝(1-gap)*λ

wherein A is a C-link frequency domain resource occupation threshold value, lambda is a scaling factor which is more than 0 and less than 1, namely a first scaling factor, and lambda can be a fixed value or can be set according to parameters indicated by a base station. The threshold value or the threshold value calculation parameter may be directly indicated by the base station, or a restriction set may be formulated, where the base station indicates an index value in the restriction set.

For example, fig. 4 is a second implementation schematic diagram of determining a link transmission mode of a repeater according to the embodiment of the present application, referring to fig. 4, if the repeater reports a frequency domain guard interval value, that is, a gap value, to the base station, and the base station sets λ to 0.75, a= (1-gap) ×λ may be obtained as a= (1-0.33) ×0.75=0.5. Referring to the left side, the occupation ratio of the C-link frequency domain resource is 0.33 and is smaller than 0.5, namely, the occupation ratio of the C-link frequency domain resource is smaller than the threshold value A, and the repeater can send FLB on the symbol or the time slot. Referring to the right side, the occupation ratio of the C-link frequency domain resource is 0.66 and is larger than 0.5, namely, the occupation ratio of the C-link frequency domain resource is larger than the threshold value A, the repeater cannot send the FLB on the symbol or the time slot, and only the FLB forwarding in the TDM mode can be performed. Similarly, let the repeater report the frequency domain guard interval value, that is, the gap value, to the base station as 2RB, the total number of frequency domain resource blocks as 6RB, and the base station set λ as 0.75, then a= (6-2) 0.75=3 RB. Referring to the left side, the frequency domain resource occupation ratio of the C-link is 2RB and is smaller than 3RB, namely the frequency domain resource occupation ratio of the C-link is smaller than the threshold value A, and the repeater can send FLB on the symbol or the time slot. Referring to the right side, the occupation ratio of the C-link frequency domain resources is 4RB and is larger than 3RB, namely, the occupation ratio of the C-link frequency domain resources is larger than the threshold value A, the repeater cannot send the FLB on the symbol or the time slot, and only FLB forwarding in the TDM mode can be performed.

Specifically, on a symbol or a time slot where the C-link is located, when the frequency domain resource position of the C-link and the restriction area have overlapping areas, this means that at this time, because the occupied bandwidth of the C-link is large, the base station cannot ensure that a sufficient interval can be reserved between the bandwidths of the C-link and the FLB for avoiding interference, and then the repeater cannot transmit the FLB on the symbol or the time slot, and only FLB forwarding in the TDM mode can be performed. When the frequency domain resource position of the C-link and the limiting region have no overlapping region, the base station can ensure that enough interval can be reserved between the bandwidths of the C-link and the FLB for avoiding interference because the occupied bandwidth of the C-link is smaller, and the repeater can send the FLB on the symbol or the time slot, namely the FLB forwarding in the FDM mode can be performed. The base station may preset a set, and indicate the configured C-link frequency domain resource restriction region through an index value. The base station may indicate one or more C-link frequency domain resource restriction regions, and the frequency domain positions of the resource restriction regions may be continuous or discontinuous.

Specifically, the C-link frequency domain resource restriction area is related to a frequency domain guard interval value (gap value) reported by the repeater, and gaps 1-N respectively represent different frequency domain guard interval values.

Specifically, the base station may calculate the C-link frequency domain resource restriction region according to the gap value, where the calculation method includes, but is not limited to, the following methods:

wherein N is a C-link frequency domain resource restriction area, w is bandwidth granularity of each resource restriction area, α is a scaling factor greater than 1, i.e. the second scaling factor, which may be a fixed value or may be set according to parameters indicated by the base station.

In addition, the base station may indicate a restricted area or an unrestricted area, and the relationship between the restricted area and the unrestricted area is that the restricted area and the unrestricted area are both unrestricted areas. For example, the base station configures the C-link frequency domain resource unrestricted region to indicate a link transmission mode through higher layer signaling.

For example, fig. 5 is a third implementation schematic diagram for determining a link transmission mode of a repeater according to the embodiment of the present application, referring to fig. 5, a blank resource block is set as a non-limiting area, a resource block with a diagonal background is set as a limiting area, and a limiting area configured by a network device is three consecutive resource blocks. Referring to the left side, on a symbol or a time slot where the C-link is located, the frequency domain resource position of the C-link and the restriction area do not have an overlapping area, namely, the C-link does not occupy the restriction area, at this time, because the occupied bandwidth of the C-link is smaller, the base station can ensure that a sufficient interval can be reserved between the bandwidths of the C-link and the FLB for avoiding interference, and the repeater can send the FLB on the symbol or the time slot, namely, the FLB forwarding in the FDM mode can be performed. Referring to the right side, on a symbol or a time slot where the C-link is located, an overlapping area exists between the frequency domain resource position of the C-link and the limiting area, namely, the C-link occupies the limiting area, at this time, because the occupied bandwidth of the C-link is large, the base station cannot ensure that a sufficient interval can be reserved between the bandwidths of the C-link and the FLB for avoiding interference, and then the repeater cannot send the FLB on the symbol or the time slot, and only FLB forwarding in a TDM mode can be performed.

The embodiment of the application provides a method for determining a link transmission mode of a repeater, which is used for solving the problem of how to determine the adopted link transmission mode of the repeater, and realizing interference suppression and energy saving. The method for determining the link transmission mode of the repeater on the network device side will be described below, and it will be understood by those skilled in the art that the method for determining the link transmission mode of the repeater on the network device side corresponds to the method for determining the link transmission mode of the repeater on the repeater side, so that corresponding technical effects can be achieved.

Fig. 6 is a second flowchart of a method for determining a link transmission mode of a repeater according to an embodiment of the present application, and referring to fig. 6, the embodiment of the present application provides a method for determining a link transmission mode of a repeater, which is applied to a network device, and includes:

step 601, receiving a transmission capability type reported by a repeater, wherein the transmission capability type is used for indicating the capability of the repeater to support a transmission mode of an uplink control link C-link and a backhaul forwarding link FLB;

step 602, determining indication information according to the type of the transmission capability reported by the repeater, where the indication information is used by the repeater to determine a link transmission mode;

Step 603, sending the indication information to the repeater.

Specifically, the base station receives the type of the transmitting capability reported by the repeater, and then determines a link transmitting mode and indicates the link transmitting mode to the repeater according to the type of the transmitting capability and the actual scheduling resource condition.

Specifically, the base station presets a set of transmitting capacity types of the repeater through high-level parameter configuration or a system, receives an index value of the transmitting capacity type reported by the repeater, and finds a corresponding transmitting capacity type from the set of transmitting capacity types according to the index value.

Specifically, the base station indicates the link transmission mode through higher Layer signaling or L1 signaling, for example, indicates the link transmission mode that the repeater should use through parameter configuration by using higher Layer signaling, or uses L1 signaling, that is, when the repeater is scheduled to transmit Layer 1 side control information (Layer 1-Side Control Information, L1-SCI) information to the repeater, one bit (bit) indication information is added to indicate the link transmission mode that the repeater should use. The L1 layer is the physical layer. This way, it may be referred to as explicit indication, i.e. directly by information.

Specifically, the base station may preset a default link transmission mode through high-level parameter configuration, for example, set the default link transmission mode through RRC signaling. In an alternative embodiment, the network device does not send the indication information determined according to the type of transmission capability reported by the repeater to the repeater. And the network equipment sends indication information for indicating the default link transmission mode of the repeater to the repeater through Radio Resource Control (RRC) signaling.

a TDM link transmission mode; or,

The methods provided in the embodiments of the present application are based on the same application conception, so that implementation of the methods on the repeater side and the network device side can be referred to each other, and repeated parts are not repeated.

The methods provided in each of the above embodiments of the present application are illustrated by the following specific examples.

Example 1: the repeater explicitly reports the transmission capacity type, and the base station explicitly indicates the repeater link transmission mode;

specifically, the base station presets the repeater sending capability type set through high-level parameter configuration or a system. The set of repeater transmit capability types may be categorized in different ways, alternative categorizations including, but not limited to, the following:

a set comprising three transmission capability types, such as: { TDM, simultaneously, both TDM and simultaneously }, wherein TDM represents a transmission capability type of a link transmission mode supporting time division multiplexing TDM, simultaneousy represents a transmission capability type of a link transmission mode supporting simultaneous transmission, and both TDM and simultaneously represents a transmission capability type of a link transmission mode supporting TDM and simultaneous transmission.

A set comprising two types of transmission capabilities, such as: { TDM, simultaneously }, wherein TDM represents a transmission capability type of a link transmission mode supporting TDM and simultaneousy represents a transmission capability type of a link transmission mode supporting TDM and simultaneous transmission.

A set of N transmission capability types, N being a positive integer, for example: { gap1, gap2, … …, gapN }, wherein gap1-N respectively represent different frequency domain guard interval values, when the FDM transmission mode is adopted, interference between the uplink C-link and the FLB transmission signals can be influenced by the frequency domain resource allocation of the C-link and the FLB, when the interval between the two frequency domain resources is larger, the interference value is relatively smaller, and when the interval is smaller, the interference value is relatively larger. The frequency domain guard interval may be considered as an ability of the repeater to suppress interference between the transmission signals of the uplink C-link and FLB, even though the repeater considers an interval between frequency domain resources where interference does not exist between the transmission signals of the uplink C-link and FLB. The gap value is the number of Resource Blocks (RBs) or the bandwidth, and when the gap value is equal to the maximum number of RBs or the maximum working bandwidth of the repeater, the C-link and the FLB cannot be transmitted at the same time, and the repeater supports the TDM link transmission mode. In the case where the gap value is equal to zero, the bandwidth positions indicating the C-link and the FLB may be adjacent, and the repeater may transmit the C-link and the FLB at the same time.

The repeater selects and reports the index value from the repeater transmitting capability type set according to the self capability, hardware parameters and the like, and reports the index value through the RRC layer parameters or the MAC-CE.

The default link transmission mode of the repeater may be pre-specified by the system, and when the repeater does not receive the transmission mode indication signaling, the default link transmission mode of the repeater is adopted, and specifically, the base station may indicate the default link transmission mode through an RRC layer parameter.

The base station determines and indicates the link transmission mode of the repeater according to the reporting capability of the repeater and the actual scheduling condition, for example, indicates the link transmission mode through SCI signaling.

Example 2: the repeater explicitly reports the type of transmission capability, and the base station implicitly indicates the repeater link transmission mode;

The base station configures a C-link frequency domain resource duty ratio threshold or an occupied resource number threshold through a high-layer parameter, and specifically indicates the C-link frequency domain resource duty ratio threshold or the occupied resource number threshold through an RRC layer parameter.

And the repeater determines a transmission mode according to the frequency domain resource allocation condition of the C-link. On the symbol or time slot where the C-link is located, when the frequency domain resource duty ratio or bandwidth of the C-link is larger than the threshold value A, the base station cannot ensure that enough interval can be reserved between the bandwidths of the C-link and the FLB for avoiding interference because the occupied bandwidth of the C-link is larger, and then the repeater cannot send the FLB on the symbol or time slot, and only the FLB forwarding in the TDM mode can be performed. When the frequency domain resource duty ratio or bandwidth of the C-link is smaller than the threshold value A, the base station can ensure that enough interval can be reserved between the bandwidths of the C-link and the FLB for avoiding interference because the occupied bandwidth of the C-link is smaller, and the repeater can send the FLB on the symbol or the time slot, namely the FLB forwarding in the FDM mode can be performed.

Example 3: the repeater explicitly reports the type of transmission capability, and the base station implicitly indicates the repeater link transmission mode;

The repeater selects and reports the index value from the repeater transmitting capability type set according to the self capability, hardware parameters and the like, and specifically reports the index value through the RRC layer parameters or the MAC-CE.

The base station configures a C-link frequency domain resource restriction area and/or an unrestricted area through a high layer, and indicates the C-link frequency domain resource restriction area and/or the unrestricted area through an RRC layer parameter.

And the repeater determines a transmission mode according to the frequency domain resource allocation condition of the C-link. When the frequency domain resource position of the C-link and the limiting area have overlapping areas on the symbol or the time slot where the C-link is located, the base station cannot ensure that enough interval can be reserved between the bandwidths of the C-link and the FLB for avoiding interference because the occupied bandwidth of the C-link is larger at the moment, and then the repeater cannot send the FLB on the symbol or the time slot and can only forward the FLB in the TDM mode. When the frequency domain resource position of the C-link and the limiting region have no overlapping region, the base station can ensure that enough interval can be reserved between the bandwidths of the C-link and the FLB for avoiding interference because the occupied bandwidth of the C-link is smaller, and the repeater can send the FLB on the symbol or the time slot, namely the FLB forwarding in the FDM mode can be performed.

Example 4: the repeater implicitly reports the transmission capacity type, and the base station explicitly indicates the repeater link transmission mode;

Specifically, the base station configures, through higher layer parameters, random access resource parameters that can be used by the repeater of an unused type, and the set of repeater transmission capability types can be classified in different manners, and the optional classification manners are not limited to the following manners:

And the repeater selects corresponding random access resources to carry out random access according to the self capacity, hardware parameters and the like.

The base station determines the capacity of the repeater according to the random access resource of the repeater, determines and indicates the sending mode of the repeater according to the actual scheduling condition, and indicates the sending mode through SCI signaling.

Example 5: the repeater implicitly reports the type of transmission capability, and the base station implicitly indicates the repeater link transmission mode;

specifically, the base station configures, through higher layer parameters, random access resource parameters that can be used by the repeater of an unused type, and the set of repeater transmission capability types can be classified in different manners, where the optional classification manners include, but are not limited to, the following manners:

The base station configures a C-link frequency domain resource duty ratio threshold or an occupied resource number threshold through a high layer, and specifically indicates the C-link frequency domain resource duty ratio threshold or the occupied resource number threshold through an RRC layer parameter.

Example 6: the repeater implicitly reports the type of transmission capability, and the base station implicitly indicates the repeater link transmission mode;

specifically, the base station configures, through higher layer parameters, random access resource parameters that can be used by different types of repeaters, and the set of repeater transmission capability types can be classified in different manners, where the optional classification manners include, but are not limited to, the following manners:

And the repeater selects corresponding random access resources according to the self capacity and type to carry out random access.

The base station configures a C-link frequency domain resource restriction area (or non-restriction area) through a higher layer, and specifically indicates the C-link frequency domain resource restriction area (or non-restriction area) through an RRC layer parameter.
