Based on the embodiments in the present disclosure, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present disclosure.

When describing the embodiments of the present disclosure, some concepts used in the following description are explained first.

(1) Cellular network communication

The traditional wireless communication adopts the cellular network communication mode, that is, the terminal and the network side equipment transmit uplink and downlink data/control information through the Uu interface, as shown in Figure 1.

(2) Direct communication

Direct communication refers to a method in which adjacent terminals can perform data transmission through a direct communication link (also called Sidelink or PC5) within a short distance. The wireless interface corresponding to the Sidelink link is called a direct communication interface (also called a Sidelink interface or a PC5 interface), as shown in FIG. 2 .

(3) Relay

In order to expand network coverage, you can consider introducing relays. A relay may be a terminal with a relay function. For U2N Relay, the interface between the relay terminal and the network side equipment uses the Uu interface, and the interface between the relayed user equipment (User Equipment, UE) (which can be called the remote UE) uses the direct communication interface (also called It is Sidelink interface or PC5 interface). The link between the relay terminal and the network side device may be called a backhaul link (Backhaul link) for the remote UE. U2N Relay is shown in Figure 3.

2) End-to-end bearer between the remote UE and the network-side device: that is, the end-to-end bearer established between the remote UE and the network-side device;

3) The bearer of the remote UE on the Uu interface (also referred to as the bearer of the backhaul link): that is, the bearer used to carry the data of the remote UE between the relay UE and the network side device.

3) The bearer between the relay UE and the target remote UE (also called a backhaul link bearer): that is, the bearer between the relay UE and the network side device for carrying data of the remote UE.

In this embodiment, when the communication device configures the transmission path for the first terminal and sends the transmission path configuration information to the first terminal, if the first terminal receives the transmission path Configuration information, and the transmission path configuration information includes activation and/or deactivation status indication information of each auxiliary transmission path, then the first terminal may indicate the activation and/or deactivation status of the auxiliary transmission path The information determines the state of each secondary transmission path, for example: the transmission path configuration information includes state indication information of two secondary transmission paths: the third state indication information of the first secondary transmission path and the fourth state of the second secondary transmission path Instructions. Wherein the third state indication information indicates that the state of the first auxiliary transmission path is an activated state, and the fourth state indication information indicates that the state of the second auxiliary transmission path is a deactivated state, then the first terminal determines that the first auxiliary transmission path The state of the secondary transmission path is an activated state, and it is determined that the state of the second secondary transmission path is a deactivated state.

The implementation process of the communication device performing transmission path state management when the first information is transmission path configuration information for the first terminal is described below through specific embodiments.

As shown in Figure 6, it specifically includes:

Step 1: The first terminal reports terminal capability indication information to the communication device.

In Step 1, the first terminal reports terminal capability indication information to the communication device, and the terminal capability indication information may include a capability indication of whether the first terminal supports transmission using multiple transmission paths.

Step 2: The communication device sends transmission path configuration information to the first terminal.

Before the communication device sends the transmission path configuration information to the first terminal, the communication device may also obtain some auxiliary information from the first terminal to assist in determining which transmission path is specifically configured, and the specific content of the auxiliary information I won't go into details here.

The first terminal may aggregate N direct paths and M indirect paths at the same time; or the first terminal aggregates P indirect paths at the same time, where the values of N, M, and P are integers greater than or equal to 1.

Wherein, the direct path means that the first terminal and the communication device can communicate directly without relaying through a relay terminal. Indirect path means that the communication between the first terminal and the communication device needs to be performed through a relay terminal. When the communication device configures multiple transmission paths for the first terminal, different transmission paths may be identified in the following ways:

Assuming that the communication device is the network-side device accessed by the first terminal, for the direct path: it can be identified by a cell ID, and the specific cell ID can be a cell number or a number index.

For the indirect path: you can pass the Relay UE ID, the Cell ID of the Relay UE on the Uu interface (if the Uu interface of the Relay UE has only one cell, this item can be omitted), the source address of the direct communication, the destination address of the direct communication interface, and the carrier of the direct communication interface /BWP identifier (if the direct communication interface has only one carrier/BWP, this item can be omitted).

Assuming that the communication device is the target terminal of the first terminal, then for the direct path: it can be identified by the cell ID; for the indirect path: it can be identified by the second combination of identifications, and for the direct path: it can be identified by the third combination of identifications logo. The second combination of identifications and the specific content included in the second combination of identifications will not be repeated here.

Optionally, considering that the indirect path identification information is very complicated, in order to simplify signaling overhead, when the communication device configures a transmission path for the first terminal, it may configure a transmission path identifier (path ID) for all or part of the transmission paths, so The above-mentioned Path ID may be the serial number of the transmission path or the index of the serial number.

In addition, when the communication device configures the transmission path for the first terminal, it may also perform activation/deactivation state management on each transmission path, that is, indicate the activation and/or deactivation state of the transmission path through transmission path configuration information, Specifically, it can include one of the following:

1) Path configuration is activated or deactivated by default; that is, when the first terminal receives the transmission path configuration information, the default state of each transmission path included in the transmission path configuration information is deactivated or activated; or By default, the main transmission path is activated or deactivated, and the secondary transmission path is activated or deactivated. Therefore, the first terminal activates or deactivates the corresponding transmission path.

2) During path configuration, the communication device indicates the activation and/or deactivation status of the path.

Wherein, the activation and/or deactivation state of the path indicated by the communication device during path configuration may specifically mean that the communication device adds indication information in the path configuration signaling (that is, the transmission path configuration information) to indicate the path Whether the initial state after the path is configured is an activated state or a deactivated state, so that the first terminal activates or deactivates the corresponding transmission path.

As an optional embodiment, if the first information is the transmission path activation and/or deactivation state indication information, the first terminal determines the first terminal and the first terminal according to the first information. The activation and/or deactivation status of all or part of the transmission paths between communication devices includes: the first terminal determining the activation and/or deactivation status of the transmission path according to the transmission path activation and/or deactivation status indication information or deactivated state.

In this embodiment, the first information is transmission path activation and/or deactivation status indication information sent by the communication device, and the first terminal can determine each The status of the transfer path. For example: the transmission path activation and/or deactivation state indication information includes three transmission paths configured by the communication device, and indicates that the state of the first transmission path is an activated state, and indicates that the state of the second transmission path is a deactivated state , indicating that the state of the third transmission path is a deactivated state; then the first terminal determines that the state of the first transmission path is an activated state, determines that the state of the second transmission path is a deactivated state, and determines that the state of the second transmission path The state of the three transmission paths is a deactivated state.

Optionally, when the first information is the transmission path activation and/or deactivation state indication information, the transmission path activation and/or deactivation state indication information may be radio resource control (Radio Resource Control, RRC ) signaling or a medium access control control unit (Medium Access Control Control Element, MAC CE), that is, the communication device indicates to the first terminal the activation and/or deactivation of each transmission path through RRC signaling or MAC CE active state.

As an optional embodiment, if the first information is transmission path configuration information for the first terminal, the transmission path configuration information includes: all or part of the transmission path for the first terminal by the communication device The transport path identifier for the path configuration.

In this embodiment, the communication device may configure a transmission path identifier for part or all of the transmission paths of the first terminal, specifically, a path ID may be configured for part or all of the transmission paths, and the Path ID may be a transmission path The number or the index of the number can simplify the signaling overhead.

Specifically, the transmission path identifier may include the following items:

(1) A first identifier, where the first identifier is a unique transmission path identifier configured by the communication device for each transmission path of the first terminal.

Specifically, the communication device may jointly number each path (including direct and indirect paths) aggregated by the first terminal, that is, each path corresponding to the first terminal may be uniquely identified by a path ID.

(2) The second identification, the second identification is the identification of the cell to which the transmission path belongs and the transmission path identification in the cell configured by the communication device for each transmission path of the first terminal in units of cells combination.

Specifically, the communication device may jointly number each path aggregated by the first terminal in units of a cell, and each transmission path in the cell passes the cell ID and the cell ID of the cell to which the transmission path belongs. A combination of path IDs in the path to uniquely identify it.

Specifically, for the direct transmission path in the transmission path of the first terminal, it is identified by the cell ID of the cell to which the direct transmission path belongs; for the non-direct transmission path in the transmission path of the first terminal, Taking the cell as a unit, jointly number the transmission paths in each cell aggregated by the first terminal, that is, the indirect path of the first terminal can be a combination of the cell ID of the cell to which the indirect path belongs and the path ID in the cell to uniquely identify.

Optionally, in this embodiment of the present disclosure, when the first information is the transmission path activation and/or deactivation state indication information, the communication device sends the transmission path activation and/or before deactivating the state indication information, the communications device configures transmission path configuration information for the first terminal. The following specifically explains that when the first information is the transmission path activation and/or deactivation state indication information, and the transmission path activation and/or deactivation state indication information is MAC CE, the first terminal determines the Activation and/or deactivation state mode of the transmission path described above.

As an optional embodiment, when the first information is the transmission path activation and/or deactivation status indication information, and the transmission path activation and/or deactivation status indication information is MAC CE:

In this embodiment, if in the transmission path configuration information configured by the communication device for the first terminal, the transmission path identifiers of all or part of the transmission paths of the first terminal are configured as the first identifier, then When the communication device indicates the state of the transmission path configured by the communication device for the first terminal through the MAC CE, the format of the MAC CE may be: use a bitmap (bitmap) mode in the MAC CE to indicate each transmission path Whether the corresponding path of the path ID of the path (or the path ID of each auxiliary transmission path) is activated or deactivated. Wherein, each path ID may correspond to 1 bit, and the activation/deactivation status of the path is indicated by the value of the bit. For example: if the value of this bit is 1, it means that the corresponding transmission path (or auxiliary transmission path) is activated; otherwise, if the value of this bit is 0, it means that the corresponding transmission path (or auxiliary transmission path) is deactivated. active state.

The following describes through specific embodiments that the first information is the transmission path activation and/or deactivation state indication information, and the transmission path activation and/or deactivation state indication information is MAC CE, and the transmission path configuration information In a case where the transmission path identifier configured in is the first identifier, the communication device implements an activation and/or deactivation state management process for the transmission path of the first terminal.

As shown in Figure 7, specifically include:

The first terminal reports terminal capability indication information to the communication device on the network, where the terminal capability indication information may include a capability indication of whether the first terminal supports transmission using multiple transmission paths.

Before the communication device sends the transmission path configuration information to the first terminal, the communication device may obtain auxiliary information from the first terminal to assist in determining which transmission path is specifically configured, and the specific content of the auxiliary information is here I won't go into details.

Wherein, the direct path means that the first terminal and the communication device can communicate directly without relaying through a relay terminal. Indirect path means that the communication between the first terminal and the communication device needs to be performed through a relay terminal. When the communication device configures multiple transmission paths for the first terminal, different transmission paths may be identified in the following manner:

Optionally, considering that the indirect path identification information is very complicated, in order to simplify signaling overhead, when the communication device configures a transmission path for the first terminal, it may configure a path ID for all or part of the transmission path, and the Path ID may be The number of the transmission path or the index of the number.

Optionally, one of the path ID distribution methods is: the first identifier corresponding to each path. The communication device jointly numbers each path aggregated by the first terminal, that is, each path of the first terminal can be uniquely identified by a path ID.

In addition, when the communication device configures the transmission path for the first terminal, it may also manage the activation/deactivation status of each transmission path, which may specifically include one of the following:

Step 3: The communication device performs activation and/or deactivation state management on one or more transmission paths corresponding to the first terminal.

Specifically, the communication device may indicate the path activation and/or deactivation status to the first terminal through RRC signaling or MAC CE.

If the communication device indicates the path activation and/or deactivation status through the MAC CE, the specific MAC CE format design is as follows: use a bitmap mode in the MAC CE to indicate that the path corresponding to each path ID of the first terminal is an activation status It is still in the deactivated state, each path ID corresponds to 1 bit, and the value of the bit indicates the activation/deactivation state of the path. For example: if the value of the bit is 1, it means that the path is activated; otherwise, if the value of the bit is 0, it means that the path is deactivated.

Taking the first terminal supporting up to 4 paths as an example, the specific MAC CE format can be as shown in Figure 8, wherein the R field is a reserved bit field, and Pathi is used to identify the activation/path corresponding to the transmission path whose Path ID is i. Deactivation status indication information.

If the transmission path identifier is the second identifier, the format of the MAC CE can be set to:

Mode 1: The MAC CE includes: the cell identity and bit mapping information for indicating the activation and/or deactivation status of each transmission path or each auxiliary transmission path in the cell;

or,

Mode 2: The MAC CE or the subheader corresponding to the MAC CE includes a length indication field, and the length indication field is used to indicate the length of the MAC CE; and the MAC CE includes a first indication field and a second indication field. Two indication fields, wherein the first indication field is used to indicate cell bit mapping information of all cells included in the MAC CE, and the second indication field is used to indicate each transmission path or each secondary Bitmap information of the activation and/or deactivation status of the transmission path.

In this embodiment, if in the transmission path configuration information configured by the communication device for the first terminal, the transmission path identifiers of all or part of the transmission paths of the first terminal are configured as the second identifier, then the When the communication device indicates the state of the transmission path configured by the communication device for the first terminal through the MAC CE, the format of the MAC CE may be:

For the first way: design MAC CE for the cell.

Specifically, the MAC CE includes the cell ID of the cell to which the transmission path belongs, and indicates the activation and/or deactivation status corresponding to the path ID of each transmission path (or each secondary transmission path) in the cell in a bitmap manner.

For the second method: design MAC CE for UE.

Specifically, the MAC CE can be aimed at multiple cells aggregated by the first terminal, the MAC CE is an extended MAC CE, and a length indication field (such as an L field) can be added to the MAC subheader corresponding to the MAC CE, and the The length indication field is used to indicate the length of the MAC CE. At the same time, a first indication field for indicating cell bitmap information (cell bitmap) is set in the MAC CE, and the cell bitmap information is used to indicate the activation and/or transmission path of which cells are included in the MAC CE Indication of deactivated state.

For each cell, the MAC CE also includes a cell identifier, and indicates the activation and/or deactivation status corresponding to the path ID of each transmission path (or each auxiliary transmission path) in the cell through a bitmap (that is, the first Two indicates the domain).

Optionally, when the transmission path identifier is the second identifier, and the communication device indicates the activation and/or deactivation status of the transmission path through the MAC CE, if the MAC CE is set to the above Method 1 or Method 2, the first terminal determines the activation and/or deactivation status of all or part of the transmission paths between the first terminal and the communication device according to the first information, including:

(1) According to the bit mapping information corresponding to each transmission path in the MAC CE, determine the activation and/or deactivation status of each transmission path.

In the method (1), the first terminal can judge the activation and/or deactivation state of the transmission path according to the indication of the MAC CE, that is, determine only according to the bitmap value corresponding to each path ID in the MAC CE The activation and/or deactivation status of the path ID.

or,

(2) when the state of the target transmission path indicated by the bitmap information in the MAC CE is an active state, and the cell to which the target transmission path belongs is an active state, determine that the state of the target transmission path is an active state; Otherwise, determine that the state of the target transmission path is a deactivated state; the target transmission path is any transmission path in the MAC CE.

In the method (2), the first terminal may determine the activation and/or deactivation status of the transmission path according to the cell state of the cell to which the transmission path belongs and bit mapping information corresponding to the transmission path. Wherein, the state of the cell can be determined according to the cell activation and/or deactivation state information, for example, the primary cell (Primary Cell, PCell) is always activated, and the state of the secondary cell (Secondary Cell, SCell) is activated/deactivated according to the secondary cell The indication of MAC CE (SCell activation/deactivation MAC CE) is determined; the activation and/or deactivation status of the path can be judged according to the indication of the bit mapping information in the MAC CE.

Specifically, for a certain target transmission path in the transmission path, only when the state of the cell to which the target transmission path belongs and the state corresponding to the target transmission path indicated in the MAC CE are both active, the first A terminal determines that the state of the target transmission path is an activated state, and can activate the corresponding target transmission path. Otherwise, consider the state of the target transmission path to be a deactivated state.

For example: the cell to which pathA belongs is cellA, in the MAC CE, the bit mapping information corresponding to pathA indicates that pathA is in the active state, cellA is the primary cell configured by the communication device, and the corresponding state is in the active state, then the first A terminal may determine that the pathA is in an active state, and may activate the transmission path corresponding to the pathA. If the bit mapping information corresponding to pathA indicates that pathA is in the activated state, cellA is a secondary cell configured by the communication device, and the corresponding state is in the deactivated state, then the first terminal determines that pathA is in the deactivated state; or, the pathA corresponds to The bit mapping information indicates that the pathA is in the deactivated state, cellA is the primary cell configured by the communication device, and the corresponding state is the activated state, then the first terminal determines that the pathA is in the deactivated state; or, the bit mapping information corresponding to pathA indicates The pathA is in the deactivated state, cellA is the secondary cell configured by the communication device, and the corresponding state is the deactivated state, then the first terminal determines that the pathA is in the deactivated state.

The following describes through specific embodiments that the first information is the transmission path activation and/or deactivation state indication information, and the transmission path activation and/or deactivation state indication information is MAC CE, and the transmission path configuration information In a case where the transmission path identifier configured in is the second identifier, the communication device implements an activation and/or deactivation state management process for the transmission path of the first terminal.

As shown in Figure 7, specifically include:

Optionally, one of the path ID distribution methods is: the second identifier corresponding to each path. Wherein, each path aggregated by the first terminal is jointly numbered in units of cells, that is, each path can be uniquely identified by a combination of a cell ID and a path ID in the cell.

If the communication device indicates path activation and/or deactivation status through MAC CE, the specific MAC CE format design is as follows:

Method 1: Design MAC CE for the cell.

Specifically, the MAC CE includes the cell ID of the cell to which the transmission path belongs, and indicates the activation and/or deactivation status corresponding to each path ID in the cell in a bitmap manner.

Assuming that the first terminal aggregates up to 8 cells (the cell ID can be indicated by 3 bits), and there are up to 4 different transmission paths in each cell, the format of the MAC CE is as shown in Figure 9, wherein: R is a reserved bit domain, the Cell ID is the number of the cell or the index of the cell number, and Pathi identifies the activation or deactivation status indication information corresponding to the transmission path whose Path ID is i in the cell corresponding to the Cell ID.

Method 2: Design MAC CE for UE.

For each cell, the MAC CE also includes a cell identifier, and indicates the activation and/or deactivation status (that is, the second indication field) corresponding to each path ID in the cell by means of a bitmap.

Assuming that the first terminal aggregates at most 8 cells (the Cell ID can be indicated by 3 bits), and there are at most 4 different transmission paths in the cell, the MAC CE can be as shown in Figure 10, wherein: Celli indicates whether the MAC CE contains Path activation/deactivation status indication information corresponding to the cell whose number or number index is i. The Cell ID is the number of the cell or the index of the cell number, and Pathi identifies the activation/deactivation status indication information corresponding to the path whose Path ID is i in the cell corresponding to the Cell ID.

It should be noted that, regardless of the above-mentioned MAC CE design method 1 or method 2, in this embodiment, the activation/deactivation state corresponding to the path can be determined in one of the following ways:

1) The path activation/deactivation state judgment is performed only according to the MAC CE indication, that is, the activation and/or deactivation state of the path ID is determined only according to the bitmap value corresponding to each path ID in the MAC CE.

2) jointly determine the state of the transmission path according to the activation and/or deactivation state of the transmission path indicated by the bitmap information in the MAC CE, and the activation and/or deactivation state of the cell to which the transmission path belongs. Among them, for the state of the cell, the PCell is always activated, and the SCell is determined according to the indication of the SCell activation/deactivation MAC CE. Only when the state of the cell to which the Path ID belongs and the state corresponding to the path ID indicated by the bitmap information in the MAC CE are activated, the transmission path corresponding to the Path ID is activated; otherwise, the path ID is considered to correspond to The transmission path is deactivated.

If the transmission path identifier is the third identifier, the MAC CE includes: a bitmap for indicating the activation and/or deactivation status of each non-straight-through transmission path or each auxiliary non-straight-through transmission path information.

It should be noted that the primary transmission path refers to a transmission path that is always activated; the secondary transmission path refers to a transmission path that is allowed to be deactivated. The secondary non-cut-through transmission path refers to a non-cut-through transmission path that is allowed to be deactivated.

In this embodiment, if in the transmission path configuration information configured by the communication device for the first terminal, the transmission path identifiers of all or part of the transmission paths of the first terminal are configured as the third identifier, then the When the communication device indicates the state of the transmission path configured by the communication device for the first terminal through the MAC CE, the format of the MAC CE may be:

In the MAC CE, the bitmap method is used to indicate whether the path ID of each indirect path (or each secondary non-through transmission path) corresponds to the active state or the deactivated state. Each path ID can correspond to 1 bit, and the value of the bit indicates The activation/deactivation status of the indirect path (or secondary non-through transmission path). For example: if the value of this bit is 1, it means that the indirect path (or auxiliary non-through transmission path) is active; otherwise, if the value of this bit is 0, it means that the indirect path (or auxiliary non-through transmission path) is deactivated.

Optionally, when the transmission path identifier is the third identifier, and the communication device indicates the activation and/or deactivation status of the transmission path through the MAC CE, if the MAC CE is set to include The "bit mapping information used to indicate the activation and/or deactivation status of each of the non-through transmission paths or each auxiliary non-through transmission path", the first terminal determines according to the first information The activation and/or deactivation status of all or part of the transmission path between the first terminal and the communication device includes:

(A) For the direct transmission path, the activation and/or deactivation status of the direct transmission path is determined according to the activation and/or deactivation status of the cell.

In this method (A), for the direct path in the transmission path configured by the communication device for the first terminal, it is judged whether the path is activated according to the activation and/or deactivation status of the cell, for example: direct pathA belongs If the cell is in the activated state, then the direct pathA is in the activated state, and the first terminal can activate the transmission path corresponding to the direct pathA; if the cell to which direct pathB belongs is in the deactivated state, then the direct pathB is in the deactivated state.

For the non-straight-through transmission path, (B): according to the bit mapping information corresponding to each non-straight-through transmission path in the MAC CE, determine the activation and/or deactivation status of each non-straight-through transmission path; or,

For the non-straight-through transmission path, (C): the bit mapping information corresponding to the non-straight-through transmission path in the MAC CE indicates that the state of the target non-straight-through transmission path is an active state, and the cell to which the target non-straight-through transmission path belongs is When in the activated state, determine the state of the target non-through transmission path as the activated state; otherwise, determine the state of the target non-through transmission path as the deactivated state.

In this embodiment, the method for judging the activation and/or deactivation state of the indirect path in the transmission path configured by the communication device for the first terminal may include method (B) and method (C). In the method (B), the first terminal may only perform path activation/deactivation state judgment according to the MAC CE indication, that is, determine the path only according to the bitmap value corresponding to each path ID in the MAC CE The activation/deactivation status of the ID.

For method (C), the first terminal may determine the activation and/or deactivation status of the indirect path according to the cell status of the cell to which the indirect path belongs and the bit mapping information corresponding to the indirect path. Wherein, the state of the cell can be determined according to the cell activation and/or deactivation state information, for example, the PCell is always in the active state, and the state of the SCell is determined according to the indication of the SCell activation/deactivation MAC CE; the activation and/or deactivation state of the path can be determined according to The indication of the bitmap information in the MAC CE is judged.

Specifically, for a certain target non-straight-through transmission path in the transmission path, only when the state of the cell to which the target non-straight-through transmission path belongs and the state corresponding to the target non-straight-through transmission path indicated in the MAC CE are both active, the The first terminal determines that the state of the target non-through transmission path is an activated state, and may activate the corresponding target non-through transmission path. Otherwise, consider the state of the target non-through transmission path as the deactivated state.

For example: the cell to which indirect pathA belongs is cellA, in the MAC CE, the bit mapping information corresponding to the indirect pathA indicates that the indirect pathA is in the active state, cellA is the primary cell configured by the communication device, and the corresponding state is the active state, then The first terminal may determine that the indirect pathA is in an active state, and may activate the transmission path corresponding to the indirect pathA. If the bit mapping information corresponding to indirect pathA indicates that the indirect pathA is in an activated state, cellA is a secondary cell configured by the communication device, and the corresponding state is a deactivated state, then the first terminal determines that the indirect pathA is in a deactivated state; or, The bit mapping information corresponding to indirect pathA indicates that the indirect pathA is in the deactivated state, and cellA is in the activated state, then the first terminal determines that the indirect pathA is in the deactivated state; or, the bit mapping information corresponding to indirect pathA indicates that the indirect pathA is In the deactivated state, cellA is in the deactivated state, then the first terminal determines that the indirect pathA is in the deactivated state.

The following describes through specific embodiments that the first information is the transmission path activation and/or deactivation state indication information, and the transmission path activation and/or deactivation state indication information is MAC CE, and the transmission path configuration information In a case where the transmission path identifier configured in is the third identifier, the communication device implements an activation and/or deactivation state management process for the transmission path of the first terminal.

As shown in Figure 7, specifically include:

Optionally, one of the path ID distribution methods is: the third identifier corresponding to each path. Wherein, the direct path of the first terminal is identified by the cell ID; the indirect path is jointly numbered in all cells aggregated by the first terminal, that is, the indirect path of the first terminal can be uniquely identified by the path ID.

In the MAC CE, the bitmap method is used to indicate whether the path ID of each indirect path corresponds to the activation state or the deactivation state. Each path ID corresponds to 1 bit, and the value of the bit indicates the activation/deactivation state of the indirect path. For example: if the value of the bit is 1, it means activation; otherwise, if the value of the bit is 0, it means deactivation.

Assuming that the first terminal aggregates up to 4 different transmission paths, the MAC CE schematic diagram is shown in Figure 8, wherein: R is a reserved bit field, and Pathi identifies the activation corresponding to the transmission path whose Path ID of the first terminal is i /Deactivate status indication information.

It should be noted that, in the format shown in FIG. 8 , the activation/deactivation state judgment method corresponding to the path by the first terminal includes:

For the direct path, it is determined whether the path is activated according to the activation and/or deactivation status of the cell.

There are two ways to judge the indirect path activation/deactivation status as follows:

1) Judging the path activation/deactivation state only according to the indication of the MAC CE, that is, determining the activation/deactivation state of the path ID only according to the bitmap value corresponding to each path ID in the MAC CE.

2) According to the cell status of the cell to which the indirect path belongs and the bit mapping information corresponding to the indirect path, determine the activation and/or deactivation status of the indirect path. Wherein, the state of the cell can be determined according to the cell activation and/or deactivation state information, for example, the PCell is always in the active state, and the state of the SCell is determined according to the indication of the SCell activation/deactivation MAC CE. Only when the state of the cell to which the Path ID belongs and the state corresponding to the path ID indicated by the bitmap information in the MAC CE are activated, the non-through transmission path corresponding to the Path ID is activated; otherwise, the path is considered to be The non-through transmission path corresponding to the ID is deactivated.

As an optional embodiment, when the first information is the transmission path activation and/or deactivation status indication information, and the transmission path activation and/or deactivation status indication information is MAC CE: if The transmission path is identified as the fourth identification, then the format of the MAC CE can be set to:

Mode 1: The MAC CE includes: the cell identifier and bit mapping information for indicating the activation and/or deactivation status of each non-straight-through transmission path in the cell or each auxiliary non-straight-through transmission path in the cell;

or

Mode 2: The MAC CE or the subheader corresponding to the MAC CE includes a length indication field, the length indication field is used to indicate the length of the MAC CE, and the MAC CE includes a third indication field and a fourth indication field , wherein the third indication field is used to indicate the cell bit mapping information of all cells included in the MAC CE, and the fourth indication field is used to indicate each of the non-through transmission paths or each of the non-through transmission paths in a cell Bit mapping information of the activation and/or deactivation status of the secondary non-through transmission path.

In this embodiment, if in the transmission path configuration information configured by the communication device for the first terminal, the transmission path identifiers of all or part of the transmission paths of the first terminal are configured as the fourth identifier, then the When the communication device indicates the state of the transmission path configured by the communication device for the first terminal through the MAC CE, the format of the MAC CE may be:

For the method 1: MAC CE is designed for the cell.

Specifically, the MAC CE includes the cell ID of the cell to which the non-direct transmission path (or secondary non-direct transmission path) belongs, and indicates the path of each indirect path (or each secondary non-direct transmission path) in the cell in a bitmap manner The activation and/or deactivation status corresponding to the ID.

For the method 2: design MAC CE for UE.

Specifically: the MAC CE can be aimed at multiple cells aggregated by the first terminal, the MAC CE is an extended MAC CE, and a length indication field (L field) can be added in the MAC subheader corresponding to the MAC CE, and the added The length indication field is used to indicate the length of the MAC CE. At the same time, a third indication field for indicating a cell bitmap is set in the MAC CE, and the cell bitmap is used to indicate the activation and/or deactivation status indications of the path IDs of the indirect paths of which cells are included in the MAC CE.

For each cell, the MAC CE also includes a cell ID, and indicates the activation and/or deactivation status (ie the fourth indication field).

Optionally, when the transmission path identifier is the fourth identifier, and the communication device indicates the activation and/or deactivation status of the transmission path through the MAC CE, if the MAC CE is set to the above Mode 1 or Mode 2, the first terminal determines the activation and/or deactivation status of all or part of the transmission paths between the first terminal and the communication device according to the first information, including:

(a) For the through transmission path, determining the activation and/or deactivation status of the through transmission path according to the activation and/or deactivation status of the cell.

In the method (a), for the direct path in the transmission path configured by the communication device for the first terminal, it is judged whether the path is activated according to the activation and/or deactivation status of the cell, for example: direct pathA belongs If the cell is in the activated state, then the direct pathA is in the activated state, and the first terminal can activate the transmission path corresponding to the direct pathA; if the cell to which direct pathB belongs is in the deactivated state, then the direct pathB is in the deactivated state.

It should be noted that, when the bit mapping information of the non-straight-through transmission path contained in the MAC CE, the first terminal determines the activation and/or deactivation state corresponding to the non-straight-through transmission path; When the bit mapping information included in the CE is the bit mapping information corresponding to the secondary non-straight-through transmission path, the first terminal determines the activation and/or deactivation status of the secondary non-straight-through transmission path.

In this embodiment, the method for judging the activation and/or deactivation state of the indirect path in the transmission path configured by the communication device for the first terminal may include method (b) and method (c). In the method (b), the first terminal may only judge the activation/deactivation state of the indirect path according to the MAC CE indication, that is, determine only according to the bitmap value corresponding to each indirect path ID in the MAC CE The activation/deactivation status of the indirect path ID.

For method (c), the first terminal may determine the activation and/or deactivation status of the indirect path according to the cell status of the cell to which the indirect path belongs and the bit mapping information corresponding to the indirect path. Wherein, the state of the cell can be determined according to the cell activation and/or deactivation state information, for example, the PCell is always in the active state, and the state of the SCell is determined according to the indication of the SCell activation/deactivation MAC CE; the activation and/or deactivation state of the indirect path can be Judgment is made according to the indication of the bitmap information in the MAC CE.

The following describes through specific embodiments that the first information is the transmission path activation and/or deactivation state indication information, and the transmission path activation and/or deactivation state indication information is MAC CE, and the transmission path configuration information In a case where the transmission path identifier configured in is the fourth identifier, the communication device implements an activation and/or deactivation state management process for the transmission path of the first terminal.

As shown in Figure 7, specifically include:

Optionally, one of the path ID distribution methods is: the fourth identifier corresponding to each path. Among them, the direct path to the first terminal is numbered by the cell ID; the indirect path is jointly numbered in each cell aggregated by the first terminal, that is, the indirect path of the first terminal can be unique through the combination of the cell ID and the path ID in the cell logo.

Mode 1: Design MAC CE for the cell.

Specifically, the MAC CE includes the cell ID of the cell to which the non-direct transmission path belongs, and indicates the activation and/or deactivation status corresponding to the path ID of each indirect path in the cell in a bitmap manner.

Assuming that the first terminal aggregates at most 8 cells (the Cell ID can be indicated by 3 bits), and there are at most 4 different indirect paths in the cell, the MAC CE is as shown in Figure 9, wherein: R is a reserved bit field, and the Cell ID is the number of the cell or the index of the cell number, and Pathi identifies the activation state indication information corresponding to the indirect path whose Path ID is i in the cell corresponding to the Cell ID.

Method 2: Design MAC CE for UE.

Specifically, the MAC CE can be aimed at multiple cells aggregated by the first terminal, the MAC CE is an extended MAC CE, and a length indication field (such as an L field) can be added to the MAC subheader corresponding to the MAC CE, and the The length indication field is used to indicate the length of the MAC CE. At the same time, a third indication field for indicating cell bitmap is set in the MAC CE, and the cell bitmap information is used to indicate the activation and/or deactivation status of the non-direct transmission paths of which cells are included in the MAC CE instruct. For each cell, the MAC CE also includes a cell identifier, and indicates the activation and/or deactivation status corresponding to the path ID of each indirect path in the cell (that is, the fourth indication field) in a bitmap manner.

Assuming that the first terminal aggregates at most 8 cells (the Cell ID can be indicated by 3 bits), and there are at most 4 indirect paths in the cell, the MAC CE is shown in Figure 10, where: Celli indicates whether the MAC CE contains a number or a number index It is the path activation/deactivation instruction information of the indirect path corresponding to the cell of i. The Cell ID is the number of the cell or the index of the cell number, and Pathi identifies the activation status indication information corresponding to the indirect path whose Path ID is i in the cell corresponding to the Cell ID.

It should be noted that, regardless of the above-mentioned MAC CE design mode 1 or mode 2, in this embodiment, the activation/deactivation state corresponding to the path can be determined in one of the following ways:

1) The indirect path activation/deactivation state judgment is performed only according to the indication of the MAC CE, that is, the activation/deactivation state of the indirect path is determined only according to the bitmap value corresponding to the path ID of each indirect path in the MAC CE.

2) According to the cell status of the cell to which the indirect path belongs and the bit mapping information corresponding to the indirect path, determine the activation and/or deactivation status of the indirect path. Wherein, the state of the cell can be determined according to the cell activation and/or deactivation state information, for example, the PCell is always in the active state, and the state of the SCell is determined according to the indication of the SCell activation/deactivation MAC CE. Only when the state of the cell to which the Path ID of the indirect path belongs and the state corresponding to the indirect path indicated by the bitmap information in the MAC CE are activated, the transmission path corresponding to the Path ID of the indirect path is activated; otherwise, It is considered that the transmission path corresponding to the path ID of the indirect path is deactivated.

As an optional embodiment, after the introduction of Indirect link, there may be multiple paths in a cell, for example, there are direct path and indirect path at the same time. The direct path can be identified by a cell, but if the indirect path needs to be identified, it may need to be indicated by information such as the cell identification and the Relay UE identification letter, and the signaling overhead will be more complicated. In order to simplify signaling overhead, the communication device may introduce a path ID for each transmission path when performing multipath configuration. The specific path ID design can be done in two ways:

Option 1: Each path (whether direct or indirect) corresponds to an independent path ID.

Specifically, for cells with only direct links, each cell is configured with a path ID; for cells with only indirect links, each cell is configured with a path ID; The indirect link configures different path IDs.

Option 2: Do not configure path ID for direct link, configure path ID only for indirect link.

Specifically, the Path ID is independently numbered in each cell, and different paths can be identified by cell ID+path ID; or, the Path ID is jointly numbered in all cells aggregated by the first terminal, and the indirect path can use an independent The path ID identifier.

Further, for each Path, a path activation/deactivation mechanism may be introduced. For example, when path is configured, it is deactivated by default. If it needs to be used, it needs to be activated first. The specific path activation and/or deactivation can be indicated by MAC CE. According to different path ID configuration methods, MAC CE design also has different methods:

Method 1): Each path corresponds to an independent path ID. In MAC CE, the bitmap method is used to indicate whether the path corresponding to the path ID is activated or deactivated. For example, the value of the bitmap is 1, which means activation; A value of 0 means deactivation. Taking the first terminal supporting up to 4 paths as an example, the specific MAC CE design can be shown in Figure 11.

Method 2): The Path ID is independently numbered in each cell, and the MAC CE includes cell indication information and path ID bitmap indication information. The indication information of different cells can be placed in one MAC CE, or one cell can correspond to one MAC CE. Taking one cell corresponding to one MAC CE as an example, assuming that the first terminal aggregates up to 8 cells, the MAC CE can be as shown in Figure 12.

In this mode 2), the first terminal has two ways of judging whether the indirect path is activated:

Option 1: Only when the activation/deactivation MAC CE corresponding to the Cell indicates that the cell is activated, and the path ID indicated in the above MAC CE is also activated, the indirect path corresponding to the path ID is activated; in other cases, the indirect paths are all deactivated.

Option 2: For the indirect path, only determine whether the indirect path is activated according to the indication in the above MAC CE.

Taking one cell corresponding to one MAC CE as an example, assuming that the first terminal aggregates up to 8 cells, the MAC CE can be as shown in Figure 12.

Taking MAC CE information corresponding to different cells into one MAC CE as an example, the MAC CE is shown in Figure 10. The MAC CE is an extended MAC CE, and it is necessary to add a length indication field in its corresponding MAC subheader to indicate the length of the MAC CE. Celli in the MAC CE is used to indicate whether the path ID activation/deactivation indication information of the cell numbered i is included in the MAC CE. In this case, there are two ways to determine the activation or deactivation status of each path as follows:

i) For the indirect path, only according to the MAC CE to determine whether to activate;

ii) For the indirect path, it is necessary to comprehensively judge the activation or deactivation state of the indirect path according to the state of the cell and the state corresponding to the path ID, that is, only when the cell is in the active state and the path ID indicated by the MAC CE is also in the active state, it will be activated The indirect path; otherwise, the indirect path is deactivated.

Mode 3): The Path ID is the joint number of all cells aggregated by the first terminal. For the direct path, use the SCell activation/deactivation MAC CE to indicate whether it is activated; for the indirect path, use the MAC CE to indicate whether the indirect path is activated.

Taking the first terminal supporting up to 4 paths as an example, the specific MAC CE design can be shown in Figure 11.

In this way, there are two ways to determine the activation or deactivation status of each path as follows:

a) For the indirect path, only according to the MAC CE to determine whether to activate;

b) For the indirect path, it is necessary to comprehensively judge the activation or deactivation state of the indirect path according to the state of the cell and the state corresponding to the path ID, that is, only when the cell is in the active state and the path ID indicated by the MAC CE is also in the active state, it will be activated The indirect path; otherwise, the indirect path is deactivated.
