As shown in fig. 1, a method for transmitting configuration information according to an embodiment of the present disclosure may be applied to a wireless communication system 100, which may include: network controlled relay device NCR101, network device 102 and user device 103.

Referring to fig. 1, ncr101 includes: a mobile terminal unit (Network controlled repeater Mobile termination, NCR-MT) and a Forwarding unit (Network controlled repeater-Forwarding, NCR-Fwd).

Wherein the mobile terminal unit communicates with the network device 102 via a Control link, for example, the mobile terminal unit portion may receive a Control command sent by the network device 102 via the Control link. The control command is used to control the behavior of the forwarding unit, i.e. the behavior on the Backhaul link (Backhaul link) and the Access link (Access link), such as beam pointing direction, turning on and off of forwarding, etc.

The backhaul link may be used for the forwarding unit to communicate with the network device 102 and the access link may be used for the forwarding unit to communicate with the user device 103, thereby enabling the user device 103 to communicate with the network device 102 through the NCR 101. It is understood that the NCR101 may also be in communication with a plurality of user devices 103.

It should be appreciated that the above wireless communication system 100 is applicable to both low frequency and high frequency scenarios. Application scenarios of the wireless communication system 100 include, but are not limited to, long term evolution (long term evolution, LTE) systems, LTE frequency division duplex (frequency division duplex, FDD) systems, LTE time division duplex (time division duplex, TDD) systems, worldwide interoperability for microwave access (worldwide interoperability for micro wave access, wiMAX) communication systems, cloud radio access network (cloud radio access network, CRAN) systems, future fifth Generation (5 th-Generation, 5G) systems, new Radio (NR) communication systems, or future evolved public land mobile network (public land mobile network, PLMN) systems, and the like.

The network controlled relay device NCR101 shown above may employ a user device.

Network device 102 may be an access network device (or access network site). The access network device refers to a device that provides a network access function, such as a radio access network (radio access network, RAN) base station, etc. The network device 102 may specifically include a Base Station (BS), or include a base station, a radio resource management device for controlling the base station, and the like. The network device 102 may also include relay stations (relay devices), access points, base stations in future 5G networks, base stations in future evolved PLMN networks, or NR base stations, etc. Network device 102 may be a wearable device or an in-vehicle device. The network device 102 may also be a communication chip with a communication module.

For example, network device 102 includes, but is not limited to: a next generation base station (gnodeB, gNB) in 5G, an evolved node B (eNB) in LTE system, a radio network controller (radio network controller, RNC), a Node B (NB) in WCDMA system, a radio controller under CRAN system, a base station controller (basestation controller, BSC), a base transceiver station (base transceiver station, BTS) in GSM system or CDMA system, a home base station (e.g., home evolved nodeB, or home node B, HNB), a baseband unit (BBU), a transmission point (transmitting and receiving point, TRP), a transmission point (transmitting point, TP), a mobile switching center, or the like.

The user equipment 103 may be a terminal (terminal), an access terminal, a terminal unit, a terminal station, a Mobile Station (MS), a remote station, a remote terminal, a mobile terminal (mobile terminal), a wireless communication device, a terminal agent, a terminal device, or the like. The user device 103 may be provided with wireless transceiving functionality capable of communicating (e.g., wirelessly communicating) with one or more network devices of one or more communication systems and receiving network services provided by the network devices, including, but not limited to, the illustrated network device 102.

In semi-static beam pointing to a UE, the UE needs to support at least two types: the semi-static Channel State information reference signal (CSI-State-Information Reference Signal, CSI-RS) beam indication type, semi-static scheduled beam indication type. For both types of information or traffic, NCR101 needs to support its forwarding. Thus, how to determine the relevant time domain characteristics or time domain positions of two types of semi-static beam indications is a problem to be solved.

The embodiment of the disclosure provides a communication method. Referring to fig. 2, fig. 2 is an interactive flowchart illustrating a communication method according to an exemplary embodiment, and as shown in fig. 2, the method includes steps S201 to S202, specifically:

in step S201, the network device 102 sends a first signaling to the network-controlled relay device NCR101, where the first signaling is used to activate or deactivate the semi-static beam indication configuration information.

In some possible implementations, the network device 102 may send the first signaling to the NCR101 over the control link.

In some possible implementations, the Semi-static beam indication configuration information (Semi-persistent Beam Indication Configuration) may be issued by the network device 102 to the NCR101 prior to sending the first signaling.

In an example, prior to step S201, the network device 102 sends semi-static beam indication configuration information to the NCR101 by sending radio resource control (Radio Resource Control, RRC) signaling.

In some possible implementations, the semi-static beam indication configuration information may include at least one of: the Beam configuration identity (Beam configuration ID), beam ID (Beam ID), time Resource (Time Resource), period (Periodicity), reference subcarrier spacing (Reference SCS).

In an example, each time domain resource may include one of: { slot offset value slot offset, symbol offset value symbol offset, number of sustained symbols symbol duration }.

In step S202, the NCR101 receives the first signaling.

In step S203, the NCR101 determines, according to the semi-static beam indication configuration information and/or the first signaling, a time domain position of the semi-static beam corresponding to the applied semi-static beam indication configuration information.

In some possible implementations, applying the time domain position of the semi-static beam may include: a start time domain position and an end time domain position. Wherein a starting time domain position, NCR101, starts applying the semi-static beam from that position and an ending time domain position, NCR101, ends applying the semi-static beam from that position.

In some possible implementations, NCR101 may determine a starting time domain location to apply the semi-static beam when the first signaling is the activation signaling.

In some possible implementations, when the first signaling is deactivation signaling, NCR101 may determine an ending time domain position of the applied semi-static beam.

In the embodiment of the present disclosure, in a scenario where the network device 102 configures the semi-static beam indication configuration information, the relay device 101 controlled by the network may receive the first signaling sent by the network device 102, to learn whether the semi-static beam indication configuration information is to be activated or deactivated, so as to be capable of applying the semi-static beam at an appropriate time domain location.

In the embodiments of the present disclosure, a communication method is provided, which is performed by a network-controlled relay device NCR 101. Referring to fig. 3, fig. 3 is a flowchart illustrating a communication method according to an exemplary embodiment, and as shown in fig. 3, the method includes steps S301 to S302, specifically:

in step S301, the NCR101 receives a first signaling sent by the network device 102, where the first signaling is used to activate or deactivate the semi-static beam indication configuration information.

In some possible implementations, NCR101 may receive the first signaling sent by network device 102 over the control link.

In some possible implementations, the first signaling is at least one of:

downlink control information (Downlink Control Information, DCI);

a medium access control unit (Media Access Control Control Element, MAC CE).

In an example, the first signaling is DCI for activating the semi-static beam indication configuration information. It can be appreciated that after a period of time in this example, network device 102 may again transmit DCI for deactivation.

In another example, the first signaling is a MAC CE that is used to activate the semi-static beam indication configuration information. It will be appreciated that in this example, after a period of time, the network device 102 may again transmit a MAC CE for deactivation.

In another example, the first signaling is DCI for activating the semi-static beam indication configuration information. After a period of time in this example, the network device 102 may again send the MAC CE for deactivation as the first signaling.

In some possible implementations, prior to step S301, NCR101 may also receive semi-static beam indication configuration information sent by network device 102 over a control link.

In an example, the semi-static beam indication configuration information may include at least one of: beam configuration ID, beam ID, time domain resource, period, reference SCS. It will be appreciated that the reference SCS may indicate a configuration (e.g., time domain resource) applicable under the reference SCS, and that in actual use, if the actual SCS is not the reference SCS, the scaling may be performed in combination with the relation between SCS.

In step S302, the NCR101 determines, according to the semi-static beam indication configuration information and/or the first signaling, a time domain position of the semi-static beam corresponding to the applied semi-static beam indication configuration information.

In some possible embodiments, the semi-static beam corresponding to the semi-static beam indication configuration information may be, for example, a semi-static beam of a corresponding beam ID indicated in the semi-static beam indication configuration information.

It is understood that the meaning of applying a semi-static beam refers to: the semi-static beam is used to transmit and receive information, for example, information transmitted by the network device 102 is forwarded to the user device 103 using the semi-static beam.

In the embodiments of the present disclosure, a communication method is provided, which is performed by a network-controlled relay device NCR 101. Referring to fig. 4, fig. 4 is a flowchart illustrating a communication method according to an exemplary embodiment, and as shown in fig. 4, the method includes steps S401 to S403, specifically:

in step S401, the NCR101 receives a first signaling sent by the network device 102, where the first signaling is used to activate or deactivate the semi-static beam indication configuration information.

The embodiment of step S401 may refer to the embodiment of step S301, which is not described herein.

In step S402, the NCR101 determines the corresponding first time slot according to the semi-static type of the semi-static beam indication configuration information.

In some possible embodiments, the semi-static type includes two of the following:

a first type (type 1), beam indication type of the semi-static CSI-RS;

The second type (type 2), the semi-statically scheduled beam indicates the type.

In some possible embodiments, depending on the semi-static type, a different first time slot may be used as a reference to determine the time domain location where the semi-static beam is applied.

In some possible implementations, the semi-static type is indicated by the semi-static beam indication configuration information, or by the first signaling.

In an example, the semi-static beam indication configuration information includes an information field for indicating a semi-static type, where the information field may indicate the following two time domain property types through different bit values: a semi-static first type, and a semi-static second type. Thus NCR101 can learn from the bit value of the information field whether the semi-static type is the first type or the second type.

In another example, an information field for indicating a semi-static type may be included in the first signaling, and the manner in which the information field indicates the type may be found in the previous example.

In some possible embodiments, the semi-static beam indication configuration information or the first signaling includes a first information field for indicating a semi-static type;

the first information field is an information field dedicated to indicating a semi-static type; or the first information domain multiplexes the information domain of the time domain resource containing at least the first slot offset value.

In an example, in the RRC used to send the semi-static beam indication configuration information, the first information field of the RRC may indicate the semi-static type or mode by directly indicating or implicitly indicating. The method may refer to two cases when the semi-static types of the first time slots are different, where the first time slot corresponding to the first type is defined as a first method, and the first time slot corresponding to the second type is defined as a second method.

For example, when the first information field of RRC is a first bit value, it indicates that the semi-static type is the first type; when the first information field is a second bit value, it indicates that the semi-static type is a second type. Alternatively, the first information field of the RRC indicates the first mode or the second mode.

Thus, in this example, the semi-static type may be determined by the bit value of the first information field.

In an example, in the first signaling for transmitting activation/deactivation, the first information field in the first signaling may indicate a semi-static type or manner by directly indicating or implicitly indicating. Taking the first signaling as the DCI for illustration, the first information field may be a time domain resource indication field in the multiplexed DCI or a new information field is used specifically to indicate the semi-static type. Taking the first signaling as an example of the MAC CE, the first information field may be a field in the MAC CE dedicated to indicate a semi-static type. In this example, the first information field may indicate the first type or the second type, or indicate the first manner or the second manner.

In another example, the semi-static type or manner is determined by a signaling type carrying time domain resources including at least a first slot offset value. If the time domain resource is contained in the RRC or the MAC CE, the semi-static type is considered to be a first type, namely, corresponds to a first mode; if the time domain resources are included in the DCI, the semi-static type is considered to be a second type, i.e., corresponds to a second manner.

Thus, in this example, the semi-static type may also be determined by where the time domain resource is located.

In another example, the semi-static type or manner is determined by the type of the first signaling. If the first signaling is the MAC CE, the semi-static type is considered to be a first type, namely, the first mode is corresponding; if the first signaling is DCI, the semi-static type is considered to be the second type, i.e., corresponds to the second mode.

Thus, in this example, the semi-static type may also be determined by the type of the first signaling.

In some possible implementations, when the semi-static type is the first type, the first time slot is a predefined reference starting time slot.

In an example, the reference starting slot may be, for example, a 0 frame0 slot (frame 0 slot 0). In other examples, other reference starting slots may also be defined by a protocol or configured by the network device.

In some possible embodiments, when the semi-static type is the second type, the first time slot is the time slot in which the first signaling is located.

In an example, the time slot in which the first signaling is located, for example, the time slot in which NCR101 receives the first signaling.

It will be appreciated that the above embodiments are described by taking a time slot as an example, and in other embodiments, the first time slot may be replaced by the first symbol or other time units such as the first time.

In step S403, the NCR101 determines a time domain position of the applied semi-static beam according to the first time slot and the first time slot offset value.

In some possible implementations, the determined time domain locations may include a start time domain location and an end time domain location of the application of the semi-static beam.

It will be appreciated that the starting time domain position and the ending time domain position may be time units of time slots (slots) or time units of symbols (symbols), and various embodiments of the disclosure are described by taking time slots as examples, but the time units of the time domain positions are not limited to time slots, and references may be obtained from the present embodiments when the time units are other than time slots.

In some possible embodiments, when the first signaling is the activation signaling, step S403 in the method may include the following steps S403-10, specifically:

In step S403-10, the ncr101 determines a starting time domain position of the application of the semi-static beam according to at least one of the first time slot, the first time slot offset value, and the effective position of the first signaling.

Wherein step S403-10 may be used in the first type and the second type to determine a starting time domain position of the applied semi-static beam. The time unit of the starting time domain position is still exemplified as a time slot.

In an example, when the semi-static type is the first type, NCR101 may determine a starting time domain position for applying the semi-static beam based on the first time slot, the first time slot offset value, and an effective position of the first signaling.

In this example, referring to the description of the foregoing embodiment, the first slot may be frame0 slot 0 when the semi-static type is the first type. The first slot offset value is then the slot offset indicated in the time domain resource. The specific manner in which the starting time domain position in the first type is determined in this example can be seen from the description of the embodiments described below.

In another example, when the semi-static type is the second type, NCR101 may determine a starting time domain position to apply the semi-static beam based on the first time slot and the first time slot offset value.

In this example, referring to the description of the foregoing embodiment, the first time slot is the time slot in which the first signaling is located when the semi-static type is the second type. The specific way in which the starting time domain position in the second type is determined in this example can be seen from the description of the embodiments described below.

For example, the time domain resource includes { slot offset value slot offset, symbol offset value symbol offset, number of sustained symbols symbol duration }, the first slot offset value may be slot offset in this information to distinguish from other possible slot offsets, and in the embodiment of the present disclosure, the first slot offset value is denoted as offset1. It is understood that in other embodiments, if the time domain position is in units of symbols, the first symbol offset value symbol offset may be used for the operation.

In some possible implementations, the effective location of the first signaling is: the first slot after the second slot offset value is spaced from the set slot position. Setting the time slot position as the time slot position where the relay device 101 controlled by the network receives the first signaling, or setting the time slot position as the time slot position where the relay device 101 controlled by the network sends feedback information corresponding to the first signaling; the second slot offset is predefined or configured by the network device 102.

The feedback information may refer to hybrid automatic repeat request acknowledgement information (Hybrid Automatic Repeat Reuest ACK, HARQ-ACK), among others.

In this embodiment, assuming that the set slot position is slot n and the second slot offset value is offset2, the effective position of the first signaling is: (slot n+offset 2) the first slot after.

In some possible embodiments, when the semi-static type is the first type, the starting time domain position is a first reference application time slot after the validity position, wherein the reference application time slot is determined according to the period in the first time slot and the semi-static beam indication configuration information and the first time slot offset value.

In an example, configuration information is indicated for a first type of semi-static beam, which may determine a plurality of reference application slots representing possible occasions (occalations) or possible slots of an application beam based on a first slot offset value and a period.

The reference application time slot satisfies: frame 0slot 0+offset1+n, where n=0, 1,2, …. In connection with the description of the previous embodiments, frame 0slot 0 represents the first slot under the first type, and offset1 represents the first slot offset value known from the time domain resources.

To facilitate understanding of the manner of determining the starting time domain position under this first type, a specific example is listed below:

assuming that the first slot offset value offset1 is slot 1, the period indicated by the semi-static beam indication configuration information is 10 slots, and the first slot in the first type of semi-static beam indication configuration information may be frame0 slot 0. The reference application slot may be: slots 1,slot 11,slot 21,slot31, … …. Further, assume that in this example NCR101 receives the first signaling at slot2 and that the second slot offset value offset2 is slot3, then the effective location of this first signaling is at slot6.

The starting time domain position of the application semi-static beam is in this example the first reference application slot after the validation position slot6, i.e. slot 11.

It will be appreciated that it is determined in this particular example that the semi-static beam is applied effectively for the first time after the first signaling is received. NCR101 may begin at slot 11 and apply a semi-static beam at slots 11,slot 21,slot31, … … before receiving a deactivation instruction.

In some possible embodiments, when the semi-static type is the second type, the starting time domain position of the applied semi-static beam is determined according to the first time slot and the first time slot offset value.

To facilitate understanding of the manner of determining the starting time domain position in this second type, a specific example is listed below:

assuming that the first slot offset value offset1 is slot1, the period indicated by the semi-static beam indication configuration information is 10 slots. And assume in this example that NCR101 receives the first signaling at slot5, i.e., the first slot is slot5. It should be noted that, in the second type, the NCR101 considers that the first signaling is valid when receiving the first signaling, that is, the valid location of the first signaling in the second type may be understood as the receiving location.

Then in this example the starting time domain position of the application semi-static beam is (first slot+offset 1) = (slot5+slot1) =slot6. NCR101 may start with slot6 and apply a semi-static beam at slots 6, 16, … … before receiving the deactivation signaling.

In some possible embodiments, when the first signaling is the deactivation signaling, step S403 in the method may include the following steps S403-20, specifically:

in step S403-20, the ncr101 determines an end time domain position of the applied semi-static beam according to at least one of the first time slot, the first time slot offset value, and the effective position of the first signaling.

Wherein steps S403-20 may be used in the first type and the second type to determine the end time domain position of the applied semi-static beam. The time unit ending the time domain position is still described as a time slot.

In an example, when the semi-static type is the first type, NCR101 may determine the ending time domain location of the applied semi-static beam based on the first time slot, the first time slot offset value, and the effective location of the first signaling.

In another example, when the semi-static type is the second type, NCR101 may determine an ending time domain position of the applied semi-static beam from the first time slot.

With reference to the description of the foregoing embodiments, in the first type, the first slot is may be frame0 slot 0; and when the second type is adopted, the first time slot is the time slot where the first signaling is positioned, namely the time slot where the first signaling is received. The first slot offset value offset1 may be known by the time domain resource. The effective position of the first signaling may be referred to the description of the foregoing embodiments, and will not be repeated here.

In some possible embodiments, when the semi-static type is the first type, the last reference application slot before the ending time domain position is the effective position, wherein the reference application slot is determined according to the period in the first slot and the semi-static beam indication configuration information and the first slot offset value.

The first type of lower reference application slots still satisfy: frame 0slot 0+offset1+n, where n=0, 1,2, ….

Assuming that the first slot offset value offset1 is slot 1, the period indicated by the semi-static beam indication configuration information is 10 slots, and the first slot in the first type of semi-static beam indication configuration information may be frame 0slot 0. The reference application slot may be: slots 1,slot 11,slot21,slot 31, … …. Further, assume that in this example NCR101 receives the first signaling at slot2 and that the second slot offset value offset2 is slot3, then the effective location of this first signaling is at slot6.

In this example, the starting time domain position of the application semi-static beam is the first reference application slot after the validation position slot6, i.e. slot 11. NCR101 may begin at slot 11 and apply a semi-static beam at slots 11,slot21,slot 31, … … before receiving a deactivation instruction.

Assume that NCR101 receives a deactivated first signaling at slot23 and that the first signaling is validated at slot33, i.e., the validated location of the deactivated first signaling is slot33. Then in this example the last reference application slot before the end time domain position slot33 is slot31, i.e. NCR101 may apply the semi-static beam the last time slot 31.

In some possible implementations, when the semi-static type is the second type, the last application slot is before the end time domain position is the first slot.

Wherein, the application time slot refers to: it is assumed that the time slots of the semi-static beam can be normally applied when no deactivation signaling is received.

Assume that NCR101 receives a first signaling for deactivation at slot30, and at this time, the first slot corresponding to the first signaling is updated to slot30. In this example, the ending time domain position is the last applied slot, slot26, before the first slot30, that is, the NCR101 may apply the semi-static beam the last time slot 26.

It should be noted that, the above-mentioned starting time domain position and the ending time domain position are both described by taking a time slot as an example, and in other manners, a symbol corresponding to the starting time domain position or the ending time domain position may also be determined. For example, each slot includes 14 symbols, and when the starting time domain position is the starting symbol, the starting symbol may satisfy: the 0 th symbol in the starting slot + symbol offset value is the number of symbols, wherein the symbol offset value is indicated in the time domain resource. When the termination time domain position is a termination symbol, the termination symbol may satisfy: the 0 th symbol + symbol offset value + symbol duration number of symbols in the termination slot, the symbol duration may be indicated in the time domain resource.

In the embodiments of the present disclosure, a communication method is provided, which is performed by a network-controlled relay device NCR 101. Referring to fig. 5, fig. 5 is a flowchart illustrating a communication method according to an exemplary embodiment, and as shown in fig. 5, the method includes steps S501 to S504, specifically:

in step S501, the NCR101 receives a first signaling sent by the network device 102, where the first signaling is used to activate or deactivate the semi-static beam indication configuration information.

The embodiment of step S501 may refer to the embodiment of step S301, which is not described herein.

In step S502, the NCR101 determines a semi-static type according to the type of the first signaling.

In some possible embodiments, the first signaling is taken as an example of the activation signaling, and if the first signaling is a MAC CE, the semi-static type is a first type, that is, the first manner is determined; if the first signaling is DCI, the semi-static type is the second type, i.e. the second mode is determined.

Wherein, the MAC CE and DCI can contain time domain resources; or the MAC CE and the DCI do not contain time domain resources, and the configuration information contains the time domain resources.

In step S503, the NCR101 determines the corresponding first time slot according to the semi-static type of the semi-static beam indication configuration information.

The implementation of step S503 may refer to the implementation of step S402 in the foregoing embodiment, which is not described herein.

In step S504, the NCR101 determines a time domain position of the applied semi-static beam according to the first time slot and the first time slot offset value.

The implementation of step S504 may be referred to the implementation of step S403 in the foregoing embodiment, which is not described herein.

In the embodiments of the present disclosure, it is described that the semi-static type may be determined by the type of the activation signaling, so that the starting time domain position and the ending time domain position of the semi-static beam application may be determined in a suitable manner.

A communication method is provided in an embodiment of the present disclosure, which is performed by the network device 102. Referring to fig. 6, fig. 6 is a flowchart illustrating a communication method according to an exemplary embodiment, and as shown in fig. 6, the method includes step S601, in particular:

in step S601, the network device 102 sends first signaling to the relay device 101 controlled by the network, where the first signaling is used to activate or deactivate the semi-static beam indication configuration information.

In some possible implementations, the semi-static beam indication configuration information or the first signaling includes a first information field for indicating the semi-static type.

In some possible implementations, the first information field is an information field dedicated to indicating a semi-static type; or the first information domain multiplexes the information domain of the time domain resource containing at least the first slot offset value.

In some possible implementations, the first signaling is one of:

downlink control information DCI;

the medium access control unit MAC CE.

It can be appreciated that, in all embodiments of the disclosure, reference may be made to the foregoing embodiments corresponding to fig. 2 to 5, and no further description is given here.

In the embodiment of the present disclosure, in a scenario where the network device 102 configures the semi-static beam indication configuration information, the network device 102 may activate or activate the semi-static beam indication configuration information by sending the first signaling indication, so that the network-controlled relay device 101 may apply the semi-static beam at an appropriate time domain location.

To facilitate an understanding of the disclosed embodiments, the following list of some specific examples:

in a first aspect, two semi-static beam indication (semi-persistent beam indication) types are introduced in the NCR access link, a first type and a second type, respectively.

The time domain resource corresponding to the first type may be { a starting slot is defined as a slot offset value in one period, a starting symbol is defined by a symbol offset in the slot, and a duration is defined by a symbol number }. Wherein, the starting time slot is defined as a time slot offset value indicated in a time slot offset value within one period, which is calculated by taking a first time slot frame0 slot 0 as a reference.

The time domain resource corresponding to the second type may be { the starting slot is defined as a slot offset value, the starting symbol is defined by the symbol offset within the slot, and the duration is defined by the number of symbols }. Wherein the starting time slot is defined as a time slot offset value indicated in the time slot offset values, which is calculated by taking the received first signaling as a reference.

The two semi-static types can be distinguished by different type IDs. Alternatively, the definition of the starting slot as a slot offset value within one period and the definition of the starting slot as a slot offset value can be understood as a first parameter type or mode type from which the NCR determines a semi-static type. Alternatively, the NCR determines the semi-static type based on the type of activation signaling.

The NCR determines how to apply the first time slot or offset value based on the different semi-static types, thereby determining the application time domain position (including the start time domain position and the end time domain position) of the semi-static beam.

In an example, in a first type or manner, the manner in which the time domain position is determined may be described below.

In this example, the slot offset value in the first type starts with frame 0slot 0 as a reference. The reference application time slot, i.e. the possible occasion of application (occasin), is: frame 0slot 0+offset1+n, where n=0, 1,2 …. Based on the reference application time slot, the time domain interval of the actual application semi-static wave beam is from the time when the activation signaling is effective to the time when the deactivation signaling is effective, and the actual application is the possible application time within the time domain interval. For example:

The application start time domain position of the first semi-static beam is as follows: the last reference application slot after the effective position of the activation signaling.

The last semi-static beam application position or termination time domain position is as follows: the last reference application slot before the effective position of the off-going activation signaling.

In another example, in a second type or manner, the manner in which the time domain position is determined may be described below.

In this example, the slot offset value is calculated starting with the slot in which the activation/deactivation signaling (first signaling) is received, i.e. the application opportunity (or application slot) is: slot m+offset1+n cycles, where n=0, 1,2 …. slot m is the time slot where the activation/deactivation command is received or the time slot where the NCR feedback activation/deactivation command corresponds to the HARQ-ACK.

In this example, the case where the activation signaling does not feed back the HARQ-ACK, and the deactivation command feeds back the HARQ-ACK is not excluded. For example:

the application start time domain position of the first semi-static beam is as follows: and determining slot+offset1 where the received activation signaling is.

The last semi-static beam application position or termination time domain position is as follows: the NCR feeds back the last application occasion before the slot of the HARQ-ACK.

In a second aspect, the slot offset value (e.g., offset 1) is part of the time domain resource, and may be configured in advance in RRC configuration signaling or indicated in activation signaling.

For example, when offset1 is not included in the RRC configuration signaling, offset1 is indicated in the activation signaling. When the offset1 is included in both the RRC configuration signaling and the activation signaling, the offset1 indicated in the activation signaling is set to be in control.

For another example, when the RRC configuration signaling includes offset1, the activation signaling may not include offset1.

In a third aspect, how to distinguish between a first type and a second type, or first and second modes, of a semi-static type.

In a first example, NCR distinguishes between two application modes according to different type IDs in RRC;

for example, the RRC configuration indicates SP type 1, the semi-static type is the first type, and the offset application is the first manner;

for example, in the RRC configuration, the application manner is directly indicated as the first manner, and the corresponding semi-static type is the first type.

For example, the type of the offset1 parameter is indicated in the time domain resource, where the slot offset value in the time domain resource is the first slot offset value.

In a second example, the NCR determines a semi-static type or an application mode type according to the type of the activation signaling, for example, the MAC CE activation is a first type or a first mode, and the DCI activation is a second type or a second mode.

In a third example, the NCR determines the manner in which the slot offset value is applied based on the first slot offset value in the activation signaling.

In a fourth aspect, the activation/deactivation signaling may be a MAC CE. Or the activation/deactivation signaling may be DCI.

Time domain property type { semi-static type1}

The time domain characteristic types comprise { periodic, aperiodic, semi-static first type, semi-static second type }.

Example 2:

Beam configuration ID 2

{ Beam ID1, time Domain resource ID1 })

Time domain resources

Time domain resource ID1{ the starting slot is defined as the slot offset value, the starting symbol is defined by the symbol offset within the slot, the duration is defined by the number of symbols }

Period { slot 8}

Reference SCS {15KHz or mu=0 }

The time domain property types include { periodic, aperiodic, semi-static }.

In this embodiment, when the activation signaling is MAC CE, NCR determines that the possible time slots used for each semi-static beam start from Frame 0slot 0+offset. When the activation signaling is DCI, the NCR determines that the semi-static beam application is slot+offset where the activation signaling is received.

Example 4:

when the RRC configuration includes only the beam ID and periodicity, the MAC CE signaling may include the following information fields:

an a/D field for indicating activation or deactivation;

a time domain property type field;

refer to SCS.

the SP beam configuration ID field is used to indicate the semi-static beam configuration ID or index of the RRC configuration.
