All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

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

(1) Cellular network communication

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

(2) Direct communication

Direct communication refers to the manner in which nearby terminals can communicate data over a direct communication link (also known as a sidlink or PC 5) within a close range. The wireless interface to which the sidlink link corresponds is referred to as a direct communication interface (also referred to as a sidlink interface or PC5 interface), as shown in fig. 2.

(3) Relay

To extend network coverage, the introduction of relays may be considered. The relay may be a terminal having a relay function. For U2N Relay, an interface between the Relay terminal and the network-side device uses a Uu interface, and an interface between the relayed UE (which may be referred to as a remote UE) uses a direct communication interface (also referred to as a sidlink interface or a PC5 interface). The link between the relay terminal and the network-side device may be referred to as a Backhaul link (Backhaul link) for the remote UE. U2N Relay is shown in FIG. 3.

Wherein, for layer 2 (L2) U2N Relay scenarios, bearers are divided into three categories:

1) The direct communication interface carries: namely, the bearer between the remote UE and the relay UE;

2) End-to-end bearers between the remote UE and the network side device: i.e. end-to-end bearer established between the remote UE and the network side device;

3) Bearer of the remote UE on Uu interface (may also be referred to as backhaul link bearer): i.e. the bearer between the relay UE and the network side device for carrying the remote UE data.

To extend the network coverage of the U2U, a U2U Relay is also introduced, as shown in fig. 4.

For the L2U relay scenario, the bearers are divided into three categories:

2) End-to-end bearers between the remote UE and the target remote UE: i.e. end-to-end bearer established between the remote UE and the network side device;

3) Bearer between relay UE and target remote UE (may also be referred to as backhaul link bearer): i.e. the bearer between the relay UE and the network side device for carrying the remote UE data.

After the relay device is introduced, multiple paths (or links) may exist when communication is performed between the remote terminal and the network side device or the target remote terminal, and for convenience of description, the following two terms are introduced:

through transmission path (Direct link or Direct path): i.e. the receiving and transmitting nodes can directly communicate without being transferred through a relay terminal.

Non-straight-through transmission path (index link or index path): that is, the receiving and transmitting nodes cannot directly communicate with each other, and data transmission between the receiving and transmitting nodes needs to be transferred through the relay terminal.

Specifically, the embodiment of the invention provides a multipath activation and/or deactivation state management method, which solves the problem of high power consumption caused by multiple transmission paths in a relay scene.

As shown in fig. 5, an embodiment of the present invention provides a transmission path status management method, which specifically includes the following steps:

The first information may be used to indicate an activation and/or deactivation status of one or more transmission paths between the first terminal and the communication device when the communication device configures the first terminal with a transmission path configuration for the one or more transmission paths. The first terminal may determine an activation and/or deactivation state of some or all of the transmission paths according to the first information.

According to the embodiment of the application, the communication equipment is used for carrying out activation and/or deactivation management on each transmission path of the first terminal, and the first terminal determines the activation and/or deactivation state of one or more transmission paths between the first terminal and the communication equipment according to the first information sent by the communication equipment, so that unnecessary monitoring is avoided, and the power saving effect is achieved.

In this embodiment, the relay terminal is a relay terminal used when the first terminal accesses the communication device. When the communication device performs transmission path configuration on the first terminal, multiple transmission paths may be configured, that is, multiple transmission paths between the first terminal and the communication device are configured. The "multiple transmission paths" may mean that the first terminal simultaneously aggregates N direct paths and M direct paths; or the first terminal simultaneously aggregates P direct paths, wherein the values of N, M, P are integers which are more than or equal to 1.

Step 2: the communication device transmits 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 further obtain some auxiliary information from the first terminal for assisting in determining which transmission path is specifically configured, where specific content of the auxiliary information is not described herein.

The first terminal can simultaneously aggregate N direct paths and M direct paths; or the first terminal simultaneously aggregates P direct paths, wherein the value of N, M, P is an integer greater than or equal to 1.

The direct path means that the first terminal and the communication device can directly communicate without transferring through a relay terminal. The index path means that communication between the first terminal and the communication device is required through the relay terminal. When the communication device configures a plurality of transmission paths for the first terminal, the identification modes of different transmission paths may be as follows:

Assuming that the communication device is a network side device accessed by the first terminal, for direct path: the identification may be by a cell ID, which may be a number or a number index of the cell.

For the directpath: the identification may be by a combination of a Relay UE ID, a Cell ID of the Relay UE on the Uu interface (which may be omitted if the Uu interface of the Relay UE has only one Cell), a direct communication source address, a direct communication interface destination address, and a direct communication interface carrier/BWP identification (which may be omitted if the direct communication interface has only one carrier/BWP).

Assuming that the communication device is a target terminal of the first terminal, for direct path: can be identified by cell ID; for the directpath: can be identified by a second identification combination, for direct path: the identification may be by a third identification combination. The second identification combination and the specific content contained in the second identification combination are not described herein.

Alternatively, in view of the complexity of the direct Path identification information, when the communication device configures a transmission Path for the first terminal in order to simplify signaling overhead, one Path ID may be configured for all or part of the transmission paths, where the Path ID may be a number of the transmission Path or an index of the number.

In addition, when the communication device configures a transmission path for the first terminal, the communication device may further perform activation/deactivation status management on each transmission path, that is, indicate, through the transmission path configuration information, activation and/or deactivation status of the transmission path, and may specifically include one of the following:

1) Default activation or deactivation when path is configured; when the first terminal receives the configuration information of the transmission path, defaulting the state of each transmission path contained in the configuration information of the transmission path to be a deactivation state or an activation state; or default that the main transmission path is in an activated or deactivated state, and the auxiliary transmission path is in an activated or deactivated state. Thereby enabling or disabling the corresponding transmission path for the first terminal.

2) And indicating the activation and/or deactivation state of the path by the communication equipment when the path is configured.

The step of indicating, by the communication device, the activation and/or deactivation state of the path in the path configuration may specifically be that the communication device adds indication information to path configuration signaling (i.e., the transmission path configuration information) to indicate whether the initial state after the path configuration is an activation state or a deactivation 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 status indication information, the first terminal determines, according to the first information, an activation and/or deactivation status of all or part of the transmission paths between the first terminal and the communication device, including: and the first terminal determines the activation and/or deactivation state of the transmission path according to the activation and/or deactivation state indication information of the transmission path.

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 may determine a status of each transmission path according to the transmission path activation and/or deactivation status indication information. For example: the transmission path activation and/or deactivation state indication information comprises three transmission paths configured by the communication equipment, indicates that the state of a first transmission path is an activation state, indicates that the state of a second transmission path is a deactivation state, and indicates that the state of a third transmission path is a deactivation state; 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 third transmission path is a deactivated state.

Alternatively, when the first information is the transmission path activation and/or deactivation status indication information, the transmission path activation and/or deactivation status indication information may be RRC signaling or MAC CE, that is, the communication device indicates the activation and/or deactivation status of each transmission path to the first terminal through RRC signaling or MAC CE.

As an optional embodiment, if the first information is transmission path configuration information for the first terminal, the transmission path configuration information includes: the communication device configures a transmission path identification for all or part of the transmission paths of the first terminal.

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

Specifically, the transmission path identification may include one of:

(1) A first identification configured for each transmission path of the first terminal by the communication device.

Specifically, the communication device may perform joint numbering for 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) And the second identifier is a combination of a cell identifier to which the transmission path belongs and a transmission path identifier in a cell configured by the communication device for each transmission path of the first terminal in units of cells.

Specifically, the communication device may perform joint numbering in a unit of a cell (cell) for each path aggregated by the first terminal, where each transmission path in the cell is uniquely identified by a combination of a cell ID of the cell to which the transmission path belongs and a path ID in the cell.

(3) A third identifier, the third identifier comprising: the method comprises the steps of enabling a path identifier of a straight-through transmission path and a path identifier of a non-straight-through transmission path to be the cell identifier of a cell to which the straight-through transmission path belongs; the path identifier of the non-through transmission path is a unique transmission path identifier configured by the communication device for all non-through transmission paths of the first terminal.

Specifically, for a through transmission path in the transmission paths of the first terminal, identifying by a cell ID of a cell to which the through transmission path belongs; and carrying out joint numbering on all non-straight-through transmission paths aggregated by the first terminal for the non-straight-through transmission paths in the transmission paths of the first terminal, wherein the non-straight-through transmission paths are uniquely identified by a non-straight-through transmission path identifier (path ID) of the first terminal.

(4) A fourth identification, the fourth identification comprising: the method comprises the steps of transmitting path identifiers of straight-through transmission paths and path identifiers of non-straight-through transmission paths, wherein the path identifiers of the straight-through transmission paths are cell identifiers of cells to which the straight-through transmission paths belong; the path identifier of the non-through transmission path is a combination of a cell identifier to which the non-through transmission path belongs and a transmission path identifier in a cell configured by the communication device for each transmission path of the first terminal in units of cells.

Specifically, for a through transmission path in the transmission paths of the first terminal, identifying by a cell ID of a cell to which the through transmission path belongs; and for the non-direct transmission path in the transmission paths of the first terminal, carrying out joint numbering on the transmission paths in each cell aggregated by the first terminal by taking a cell as a unit, namely, the direct path of the first terminal can be uniquely identified by the combination of the cell ID of the cell to which the direct path belongs and the path ID in the cell.

Optionally, in an embodiment of the present application, when the first information is the transmission path activation and/or deactivation status indication information, before the communication device sends the transmission path activation and/or deactivation status indication information to the first terminal, the communication device configures transmission path configuration information for the first terminal. The manner in which the first terminal determines the activation and/or deactivation state of the transmission path 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 the MAC CE will be described in detail.

As an alternative embodiment, in the case that 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 a MAC CE:

In this embodiment, if the transmission path identifier of all or part of the transmission paths of the first terminal is configured as the first identifier in the transmission path configuration information configured by the communication device for the first terminal, when the communication device indicates, by using the MAC CE, the state of the transmission paths configured by the communication device for the first terminal, the format of the MAC CE may be: a bit map (bitmap) manner is used in the MAC CE to indicate whether the corresponding path of the path ID of each transmission path (or the path ID of each secondary transmission path) is in an active state or in a deactivated state. Wherein, each path ID may correspond to 1bit, and the activation/deactivation status of the path is indicated by the value of the bit. Such as: if the bit is 1, the corresponding transmission path (or auxiliary transmission path) is in an activated state; otherwise, if the bit is 0, the corresponding transmission path (or the auxiliary transmission path) is in a deactivated state.

The implementation process of the communication device for performing activation and/or deactivation status management on the transmission path of the first terminal 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 the MAC CE and the transmission path identifier configured in the transmission path configuration information is the first identifier is described below by using a specific embodiment.

As shown in fig. 7, specifically, the method includes:

step 1: the first terminal reports terminal capability indication information to the communication equipment.

The first terminal reports terminal capability indication information to the communication device of the network, wherein the terminal capability indication information can comprise capability indication whether the first terminal supports transmission by using a plurality of transmission paths.

Before the communication device sends the transmission path configuration information to the first terminal, the communication device may acquire auxiliary information from the first terminal to assist in determining which transmission path is specifically configured, and specific content of the auxiliary information is not described herein.

Optionally, one of the allocation manners of the path ID is: and the first identifier corresponds to each path. Wherein the communication device performs joint numbering on 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 a transmission path for the first terminal, the communication device may further manage an activation/deactivation state of each transmission path, and may specifically include one of the following:

Step 3: and the communication equipment 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 state through the MAC CE, the specific MAC CE format is designed as follows: and indicating whether each path ID of the first terminal corresponds to an active state or a deactivated state by using a bitmap mode in the MAC CE, wherein each path ID corresponds to 1bit, and indicating the active/deactivated state of the path through the value of the bit. Such as: if the bit is 1, the path is in an activated state; otherwise, if the bit is 0, it indicates that the path is in a deactivated state.

Taking the example that the first terminal supports at most 4 paths, a specific MAC CE format may be shown in fig. 8, where an R field is a reserved bit field, and Pathi is used to identify activation/deactivation status indication information corresponding to a transmission Path with a Path ID of i.

if the transmission path identifier is the second identifier, the format of the MAC CE may be set as follows:

mode one: the MAC CE includes: the cell identifier and bit mapping information for indicating the activation and/or deactivation state of each transmission path or each auxiliary transmission path in the cell;

or alternatively, the process may be performed,

mode two: the MAC CE or a sub header (sub header) corresponding to the MAC CE comprises a length indication field, wherein the length indication field is used for indicating the length of the MAC CE; the MAC CE includes a first indication field and a second indication field, where 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 bit mapping information of activation and/or deactivation states of each transmission path or each auxiliary transmission path in one cell.

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

for the first mode: the MAC CE is designed for the cell.

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

For the second mode: the MAC CE is designed for the UE.

Specifically, for a plurality of cells aggregated by the first terminal, the MAC CE is an elongated MAC CE, and a length indication field (e.g., an L field) may be added to a MAC subheader corresponding to the MAC CE, where the added length indication field is used to indicate a length of the MAC CE. Meanwhile, a first indication field for indicating cell bitmap information (cell bitmap) is set in the MAC CE, where the cell bitmap information is used to indicate activation and/or deactivation states of transmission paths of which cells are included in the MAC CE.

For each cell, the MAC CE further includes a cell identifier, and indicates, by using a bitmap manner, an activation and/or deactivation state (i.e., the second indication field) corresponding to the path ID of each transmission path (or each auxiliary transmission path) in the cell.

Optionally, in the case that the transmission path identifier is the second identifier and the communication device indicates the activation and/or deactivation state of the transmission path through the MAC CE, if the MAC CE is set in the first mode or the second mode, the first terminal determines, according to the first information, the activation and/or deactivation state of all or part of the transmission paths between the first terminal and the communication device, including:

(1) And determining the activation and/or deactivation state of each transmission path according to the bit mapping information corresponding to each transmission path in the MAC CE.

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

Or alternatively, the process may be performed,

(2) When the state of a target transmission path indicated by bit mapping information in the MAC CE is an active state and a cell to which the target transmission path belongs is an active state, determining that the state of the target transmission path is an active state; otherwise, determining the state of the target transmission path as a deactivation state; the target transmission path is an arbitrary transmission path within the MAC CE.

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

Specifically, for a certain target transmission path in the transmission paths, 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 states, the first terminal determines that the state of the target transmission path is an active state, and may activate the corresponding target transmission path. Otherwise, the state of the target transmission path is considered to be a deactivated state.

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

The implementation process of the communication device for performing activation and/or deactivation status management on the transmission path of the first terminal 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 the MAC CE and the transmission path identifier configured in the transmission path configuration information is the second identifier is described below by using a specific embodiment.

As shown in fig. 7, specifically, the method includes:

Optionally, one of the allocation manners of the path ID is: and the second identifier corresponds to each path. Each path aggregated by the first terminal is jointly numbered in a cell unit, 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 the path activation and/or deactivation state through the MAC CE, the specific MAC CE format is designed as follows:

mode one: the MAC CE is designed for the cell.

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

Assuming that the first terminal aggregates at most 8 cells (cell IDs may be indicated by 3 bits), and there are at most 4 different transmission paths in each cell, the format of the MAC CE is shown in fig. 9, where: r is a reserved bit field, the Cell ID is the number of the Cell or the index of the Cell number, and the Pathi identifies the activation or deactivation state indication information corresponding to the transmission Path with the Path ID i in the Cell corresponding to the Cell ID.

Mode two: the MAC CE is designed for the UE.

For each cell, the MAC CE further includes a cell identifier, and indicates, by using a bitmap manner, an activation and/or deactivation state (i.e., the second indication field) corresponding to each path ID in the cell.

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

It should be noted that, in this embodiment, one of the following ways of determining the activation/deactivation status corresponding to the path may be used, regardless of the first or second MAC CE design way:

1) And judging the activation/deactivation state of the path ID only according to the MAC CE indication, namely determining the activation and/or deactivation state of the path ID only according to the bitmap value corresponding to each path ID in the MAC CE.

2) And determining the state of the transmission path according to the activation and/or deactivation state of the transmission path indicated by the bit mapping information in the MAC CE and the activation and/or deactivation state of the transmission path home cell. Wherein, for the state of the cell, the PCell is always activated, and the SCell is determined according to the indication of SCell activation/deactivation MAC CE. Only when the state of a cell to which a Path ID belongs and the state corresponding to the Path ID indicated by the bit mapping information in the MAC CE are both activated, activating a transmission Path corresponding to the Path ID; otherwise, the transmission path corresponding to the path ID is considered to be deactivated.

If the transmission path identifier is the third identifier, the MAC CE includes: bit map information indicating the activation and/or deactivation status of each of said non-pass-through transmission paths or each of the secondary non-pass-through transmission paths.

The main transmission path is a transmission path always in an active state; the secondary transmission path refers to a transmission path that is allowed to be deactivated. The secondary non-pass-through transmission path refers to a non-pass-through transmission path that is allowed to be deactivated.

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

the bitmap mode is used in the MAC CE to indicate whether the path ID corresponding to each direct path (or each auxiliary non-through transmission path) is in an active state or a deactivated state, and each path ID may correspond to 1bit, where the value of the bit indicates the active/deactivated state of the direct path (or each auxiliary non-through transmission path). Such as: if the bit is 1, the indication path (or the auxiliary non-through transmission path) is in an active state; otherwise, if the bit is 0, it indicates that the direct path (or the auxiliary non-through transmission path) is in a deactivated state.

Optionally, in the case that the transmission path identifier is the third identifier and the communication device indicates the activation and/or deactivation state of the transmission path through the MAC CE, if the MAC CE is set to include the "bit map information for indicating the activation and/or deactivation state of each of the non-through transmission paths or each of the auxiliary non-through transmission paths", the first terminal determines the activation and/or deactivation state of all or part of the transmission paths between the first terminal and the communication device according to the first information, including:

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

In the method (a), for a direct path in a transmission path configured by the communication device for the first terminal, whether the path is activated is determined according to an activation and/or deactivation state of a cell, for example: the cell to which the direct path A belongs is in an active state, and the direct path A is in an active state, so that the first terminal can activate a transmission path corresponding to the direct path A; the cell to which direct path b belongs is in a deactivated state, and the direct path b is in a deactivated state.

For a non-pass-through transmission path, (B): determining the activation and/or deactivation state of each non-through transmission path according to the bit mapping information corresponding to each non-through transmission path in the MAC CE; or alternatively, the process may be performed,

for a non-pass-through transmission path, (C): when bit mapping information corresponding to a non-through transmission path in the MAC CE indicates that the state of a target non-through transmission path is an active state and a cell to which the target non-through transmission path belongs is an active state, determining that the state of the target non-through transmission path is an active state; otherwise, determining the state of the target non-through transmission path as a deactivated state.

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

For the method (C), the first terminal may determine the activation and/or deactivation state of the direct path according to the cell state of the cell to which the direct path belongs and the bit mapping information corresponding to the direct path. Wherein the state of the cell may be determined according to cell activation and/or deactivation state information, e.g. PCell always activated state, SCell state is determined according to an indication of SCell activation/deactivation MAC CE; the activation and/or deactivation status of the path may be determined based on an indication of the bit map information in the MAC CE.

Specifically, for a certain target non-through transmission path in the transmission paths, only when the state of the cell to which the target non-through transmission path belongs and the state corresponding to the target non-through transmission path indicated in the MAC CE are both active states, the first terminal determines that the state of the target non-through transmission path is an active state, and can activate the corresponding target non-through transmission path. Otherwise, the state of the target non-pass-through transmission path is considered to be a deactivated state.

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

The implementation process of the communication device for performing activation and/or deactivation status management on the transmission path of the first terminal 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 the MAC CE and the transmission path identifier configured in the transmission path configuration information is the third identifier is described below by using a specific embodiment.

As shown in fig. 7, specifically, the method includes:

Optionally, one of the allocation manners of the path ID is: and the third identifier corresponds to each path. The direct path of the first terminal is identified through a cell ID; and combining numbers in all cells aggregated by the first terminal through the direct path, namely the direct path of the first terminal can be uniquely identified through the path ID.

and indicating whether the path ID of each redirect path corresponds to an activated state or a deactivated state by using a bitmap mode in the MAC CE, wherein each path ID corresponds to 1bit, and indicating the activated/deactivated state of the redirect path through the value of the bit. Such as: if the bit is 1, the activation is indicated; otherwise, if the bit takes a value of 0, the deactivation is indicated.

Assuming that the first terminal aggregates at most 4 different transmission paths, a MAC CE schematic diagram is shown in fig. 8, where: r is a reserved bit field, and Pathi identifies activation/deactivation state indication information corresponding to a transmission Path with a Path ID of the first terminal as i.

It should be noted that, in the format shown in fig. 8, the method for determining the activation/deactivation status of the first terminal corresponding to the path includes:

and for the direct path, judging whether the path is activated according to the cell activation and/or deactivation state.

For the direct path activation/deactivation status judgment, there are two modes:

1) And judging the path activation/deactivation state only according to the indication of the MAC CE, namely 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) And determining the activation and/or deactivation state of the direct path according to the cell state of the cell to which the direct path belongs and the bit mapping information corresponding to the direct path. Wherein the state of the cell may be determined according to cell activation and/or deactivation state information, e.g. PCell always activated state, SCell state is determined according to an indication of SCell activation/deactivation MAC CE. Only when the state of a cell to which a Path ID belongs and the state corresponding to the Path ID indicated by the bit mapping information in the MAC CE are both activated, activating a non-through transmission Path corresponding to the Path ID; otherwise, the non-through transmission path corresponding to the path ID is considered to be deactivated.

As an alternative embodiment, in the case that 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 a MAC CE: if the transmission path identifier is the fourth identifier, the format of the MAC CE may be set as follows:

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

or alternatively

Mode 2: the MAC CE or the sub-header corresponding to the MAC CE comprises a length indication field, the length indication field is used for indicating the length of the MAC CE, the MAC CE comprises a third indication field and a fourth indication field, wherein the third indication field is used for indicating the cell bit mapping information of all cells contained in the MAC CE, and the fourth indication field is used for indicating the bit mapping information of the activation and/or deactivation state of each non-through transmission path or each auxiliary non-through transmission path in one cell.

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

For the mode 1: the MAC CE is designed for intra-cell.

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

For the mode 2: the MAC CE is designed for the UE.

Specific: the MAC CE may be an elongated MAC CE for a plurality of cells aggregated by the first terminal, and a length indication field (L field) may be added to a MAC subheader corresponding to the MAC CE, where the added length indication field is used to indicate a length of the MAC CE. Meanwhile, a third indication field for indicating a cell bitmap is set in the MAC CE, and the cell bitmap is used for indicating activation and/or deactivation status indication of the path ID of the directional path of which cells the MAC CE contains.

For each cell, the MAC CE further includes a cell ID identifier, and indicates, by using a bitmap manner, an activation and/or deactivation state (i.e. the fourth indication field) corresponding to a path ID of each direct path (or each auxiliary non-through transmission path) in the cell.

Optionally, in a case where the transmission path identifier is the fourth identifier and the communication device indicates an activated and/or deactivated state of a transmission path through the MAC CE, if the MAC CE is set to mode 1 or mode 2 described above, the first terminal determines, according to the first information, an activated and/or deactivated state of all or part of the transmission path between the first terminal and the communication device, including:

In the method (a), for a direct path in a transmission path configured by the communication device for the first terminal, whether the path is activated or not is determined according to an activation and/or deactivation state of a cell, for example: the cell to which the direct path A belongs is in an active state, and the direct path A is in an active state, so that the first terminal can activate a transmission path corresponding to the direct path A; the cell to which direct path b belongs is in a deactivated state, and the direct path b is in a deactivated state.

When the bit mapping information is included in the MAC CE and is a bit mapping information of a non-through transmission path, the first terminal determines an activation state and/or a deactivation state corresponding to the non-through transmission path; and when the MAC CE contains bit mapping information corresponding to the auxiliary non-through transmission path, the first terminal determines the activation and/or deactivation state of the auxiliary non-through transmission path.

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

For the method (c), the first terminal may determine the activation and/or deactivation state of the direct path according to the cell state of the cell to which the direct path belongs and the bit mapping information corresponding to the direct path. Wherein the state of the cell may be determined according to cell activation and/or deactivation state information, e.g. PCell always activated state, SCell state is determined according to an indication of SCell activation/deactivation MAC CE; the activation and/or deactivation status of the direct path may be determined according to the indication of the bit map information in the MAC CE.

The implementation process of the communication device for performing activation and/or deactivation status management on the transmission path of the first terminal 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 the MAC CE and the transmission path identifier configured in the transmission path configuration information is the fourth identifier is described below by using a specific embodiment.

As shown in fig. 7, specifically, the method includes:

Optionally, one of the allocation manners of the path ID is: and the fourth identifier corresponds to each path. The direct path of the first terminal is numbered through a cell ID; the directives path is jointly numbered in each cell aggregated by the first terminal, that is, the directives path of the first terminal can be uniquely identified by a combination of a cell ID and a path ID in the cell.

mode 1: the MAC CE is designed for intra-cell.

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

Assuming that the first terminal aggregates at most 8 cells (Cell IDs may be indicated by 3 bits), there are at most 4 different direct paths in a Cell, the MAC CE is as shown in fig. 9, where: r is a reserved bit field, 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 direct Path with the Path ID i in the Cell corresponding to the Cell ID.

Mode 2: the MAC CE is designed for the UE.

Specifically, for a plurality of cells aggregated by the first terminal, the MAC CE is an elongated MAC CE, and a length indication field (e.g., an L field) may be added to a MAC subheader corresponding to the MAC CE, where the added length indication field is used to indicate a length of the MAC CE. Meanwhile, a third indication field for indicating the cell bitmap is set in the MAC CE, and the cell bitmap information is used for indicating the activation and/or deactivation states of the non-through transmission paths of which cells are included in the MAC CE. For each cell, the MAC CE further includes a cell identifier, and indicates, by using a bitmap manner, an activation and/or deactivation state (i.e., the fourth indication field) corresponding to the path ID of each direct path in the cell.

Assuming that the first terminal aggregates 8 cells at most (Cell ID may be indicated by 3 bits), there are 4 direct paths at most in the cells, the MAC CE is as shown in fig. 10, where: celli indicates whether the MAC CE contains a path activation/deactivation instruction information of an direct path corresponding to a cell with a number or a number index i. 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 directpath with Path ID i in the Cell corresponding to the Cell ID.

Note that, in this embodiment, whether the MAC

CE design mode

1 or 2 is described above, one of the following ways of determining the activation/deactivation states corresponding to the path may be used:

1) And judging the activation/deactivation state of the direct path only according to the indication of the MAC CE, namely determining the activation/deactivation state of the direct path only according to the bitmap value corresponding to the path ID of each direct path in the MAC CE.

2) And determining the activation and/or deactivation state of the direct path according to the cell state of the cell to which the direct path belongs and the bit mapping information corresponding to the direct path. Wherein the state of the cell may be determined according to cell activation and/or deactivation state information, e.g. PCell always activated state, SCell state is determined according to an indication of SCell activation/deactivation MAC CE. Only when the state of a cell to which a Path ID of an redirect Path belongs and the state corresponding to the redirect Path indicated by bit map information in the MAC CE are both activated, activating a transmission Path corresponding to the Path ID of the redirect Path; otherwise, the transmission path corresponding to the path ID of the direct path is considered to be deactivated.

As an alternative embodiment, after the index link is introduced, there may be multiple paths in a cell, such as direct path and direct path at the same time. The direct path may be identified by a cell, but if the direct path is to be identified, the direct path may need to be indicated by information such as a cell identifier, a Relay UE identifier, and the like, and signaling overhead may be relatively complex. To simplify signaling overhead, the communication device may introduce one path ID for each transmission path when performing multipath configuration. The specific path ID design can be in two ways:

option 1-each path (either direct or indirect path) corresponds to an independent path ID.

Specifically, for cells with direct link only, each cell is configured with a path ID; for the cells with only the direct link, each cell is configured with a path ID; for a cell containing both direct link and direct link, different path IDs may be configured for direct link and direct link, respectively.

Option 2. Path ID is not configured for direct link, path ID is configured only for direct link.

Specifically, if the Path ID is independently numbered in each cell, different paths can be identified by the cell id+path ID; alternatively, the Path ID is a combination number in all cells aggregated at the first terminal, and the direct Path may be identified using an independent Path ID.

Further, for each Path, a Path activation/deactivation mechanism may be introduced. For example, the default deactivation is performed when the path is configured, if the path is required to be used, the path is required to be activated first, and specific path activation and/or deactivation can be indicated by using a MAC CE mode. According to different path ID configuration modes, the MAC CE design has different modes:

mode 1): each path corresponds to 1 independent path ID, a bitmap mode is used in the MAC CE to indicate whether the path ID corresponds to the path to be activated or deactivated, for example, if the bitmap value is 1, the activation is indicated; otherwise, if the bitmap is 0, the bitmap is deactivated. Taking an example that the first terminal supports 4 paths at most, a specific MAC CE design may be shown in fig. 11.

Mode 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 put into one MAC CE, or one cell corresponds to one MAC CE. Taking an example that one cell corresponds to one MAC CE, assuming that the first terminal aggregates 8 cells at most, the MAC CE may be as shown in fig. 12.

In this mode 2), the first terminal has two judging modes for whether the direct path is activated:

option 1-Inrect Path corresponding to Path ID is active only if the Cell is indicated to be active in activation/deactivation MAC CE corresponding to the Cell, and Path ID is indicated to be active in the MAC CE; in the rest of the cases, the direct path is in a deactivated state.

Option 2: for the directpath, it is determined whether the directpath is active only according to the indication in the MAC CE described above.

Taking an example that one cell corresponds to one MAC CE, assuming that the first terminal aggregates 8 cells at most, the MAC CE may be as shown in fig. 12.

Taking as an example that the MAC CE information corresponding to different cells is put into one MAC CE, the MAC CE is shown in fig. 10. The MAC CE is an extended MAC CE, and a length indication field needs to be added in a corresponding MAC subheader to indicate the length of the MAC CE. The Celli in the MAC CE is used to indicate whether path ID activation/deactivation indication information of a cell numbered i is contained in the MAC CE. In this case, the manner of determining the activation or deactivation state for each path may be as follows:

i) For the direct path, judging whether to activate or not only according to the MAC CE;

ii) for the directionpath, the activation or deactivation state of the directionpath needs to be comprehensively judged according to the state of the cell and the state corresponding to the path ID, namely, the directionpath is activated only when the cell is in the activation state and the path ID indicated by the MAC CE is also in the activation state; otherwise, the direct path is deactivated.

Mode 3): the Path ID is the joint number of all cells aggregated by the first terminal, and indicates whether to activate or not by using SCell activation/deactivationMAC CE for direct Path; and indicating whether the directpath is activated or not through the MAC CE for the directpath.

Taking an example that the first terminal supports 4 paths at most, a specific MAC CE design may be shown in fig. 11.

In this manner, the determination manner of the activation or deactivation state for each path may be as follows:

a) For the direct path, judging whether to activate or not only according to the MAC CE;

b) For the directionpath, the activation or deactivation state of the directionpath needs to be comprehensively judged according to the state of the cell and the state corresponding to the path ID, namely, the directionpath is activated only when the cell is in the activation state and the path ID indicated by the MAC CE is also in the activation state; otherwise, the direct path is deactivated.

Specifically, when the first information is the transmission path configuration information, the transmission path configuration information may include activation and/or deactivation status indication information of each transmission path (or each auxiliary transmission path), and the first terminal determines the activation and/or deactivation status of each transmission path (or each auxiliary transmission path) according to the activation and/or deactivation status indication information of each transmission path (or each auxiliary transmission path).

Alternatively, when the first information is the transmission path configuration information, the first terminal may default the state of each transmission path included in the transmission path configuration information to be an active state when receiving the transmission path configuration information of the first terminal. Or, the first terminal defaults to a deactivated state for each transmission path included in the transmission path configuration information when receiving the transmission path configuration information for the first terminal. Or, when the first terminal receives the transmission path configuration information for the first terminal, defaulting the state of the main transmission path configured in the transmission path configuration information to be an activated state, and the states of other auxiliary transmission paths except the main transmission path to be deactivated states.

Optionally, in an embodiment of the present application, when the first information is the transmission path activation and/or deactivation status indication information, before the communication device sends the transmission path activation and/or deactivation status indication information to the first terminal, the communication device configures transmission path configuration information for the first terminal. The following specifically describes a format design manner of the MAC CE 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 the MAC CE.

Wherein, each path ID may correspond to 1bit, and the activation/deactivation status of the path is indicated by the value of the bit.
