Background

Relay (Relay) technology in a wireless communication system is to add one or more Relay nodes between a base station and a terminal, and is responsible for forwarding wireless signals once or many times, that is, the wireless signals can reach the terminal through multiple hops.

The transmission processing method provided by the embodiments of the present application is described in detail below with reference to the accompanying drawings by using some embodiments and application scenarios thereof.

As shown in fig. 2, a transmission processing method according to an embodiment of the present application includes:

step 201, the first terminal performs a first operation when the radio resource control RRC connection reestablishment or recovery condition is satisfied and a first cell is selected, where the first operation includes one of the following steps:

entering an RRC idle state;

Therefore, for a scenario that a first terminal currently in a non-direct connection path, that is, the first terminal accesses a second network side device through a second terminal, when the first terminal meets an RRC connection reestablishment or recovery condition, cell selection and relay terminal selection can be performed, so that the first terminal can subsequently access the network side device. After the first terminal selects the first cell, it may ensure subsequent transmission by sending an RRC connection reestablishment or recovery request message to the first network side device (i.e., the network side device to which the first cell belongs), or entering an idle state.

Here, the scenario that the first terminal accesses the second network side device through the second terminal may be that the first terminal and the second terminal communicate through a sidelink, a bluetooth, and a wireless local area network WIFI. In the embodiment of the present application, a sidelink is taken as an example for explanation, where the first terminal is a remote UE and the second terminal is a relay UE.

The first cell is a cell suitable for subsequent access, and the first terminal has the capability of initiating an RRC connection reestablishment or recovery procedure from the index path to the direct path in the first cell.

In this embodiment, the first terminal enters an IDLE state RRC _ IDLE and then may initiate an RRC connection establishment procedure.

Optionally, step 201 comprises:

the first terminal determines network side equipment related information, wherein the network side equipment related information comprises whether the first network side equipment is the same as the second network side equipment and/or whether Radio Access Technology (RAT) types of the first network side equipment are the same as the second network side equipment;

and the first terminal executes the first operation according to the relevant information of the network side equipment.

That is, the remote UE may select the specifically performed first operation based on whether the first network-side device is the same as the second network-side device, and/or whether RAT types of the first network-side device and the second network-side device are the same.

Optionally, when the network-side device-related information includes that the first network-side device is the same as the second network-side device, or includes that the first network-side device is the same as the second network-side device and the RAT types of the first network-side device and the second network-side device are the same, the performing, by the first terminal, the first operation according to the network-side device-related information includes: the first terminal sends an RRC connection reestablishment or recovery request message to the first network side equipment according to the relevant information of the network side equipment;

in a case that the network-side device-related information only includes that the first network-side device is different from the second network-side device, or only includes that RAT types of the first network-side device are the same as RAT types of the second network-side device, or includes that the first network-side device is different from the second network-side device and RAT types of the first network-side device are the same as RAT types of the second network-side device, the first terminal performs the first operation according to the network-side device-related information, including: the first terminal executes the first operation according to the related information and the reference information of the network side equipment;

when the network-side device-related information only includes that the RAT types of the first network-side device and the second network-side device are different, or includes that the first network-side device and the second network-side device are different and the RAT types of the first network-side device and the second network-side device are different, the first terminal performs the first operation according to the network-side device-related information, including: the first terminal enters an RRC idle state according to the related information of the network side equipment

Thus, if the network side device related information only includes that the first network side device is the same as the second network side device, that is, the direct path and the index path belong to the same base station, the remote UE sends an RRC connection reestablishment or recovery request message to the first network side device. At this time, the first network side device and the second network side device are also of the same RAT type.

Similarly, if the related information of the network side device includes that the first network side device is the same as the second network side device and the RAT types of the first network side device and the second network side device are the same, the remote UE sends an RRC connection reestablishment or recovery request message to the first network side device.

And if the related information of the network side equipment only comprises that the RAT types of the first network side equipment and the second network side equipment are different, the remote UE enters an RRC idle state. At this time, the first network-side device and the second network-side device are different network-side devices.

Similarly, if the network side device related information includes that the first network side device is different from the second network side device and the RAT types of the first network side device and the second network side device are different, the remote UE enters an RRC idle state.

Considering that when the first network-side device is different from the second network-side device, the first network-side device and the second network-side device may be of the same RAT type or different RAT types; when the first network side device and the second network side device are of the same RAT type, the first network side device and the second network side device may be the same or different, and to perform a more applicable operation, a specific first operation is further performed based on the network side device related information and the parameter information.

Optionally, the reference information comprises at least one of:

first capability information of the first terminal, the first capability information indicating at least one of: whether cross-base station re-establishment and/or recovery is supported; whether co-RAT re-establishment and/or recovery is supported;

second capability information of the first terminal, the second capability information being used to indicate supported protocol versions;

network indication information.

That is, when the first network-side device and the second network-side device are different network-side devices and/or different RAT types, the first operation to be executed is selected according to at least one of the first capability information of the first terminal, the second capability information of the first terminal, and the network indication information.

Wherein, for the first capability information, it can be implemented as:

1. when only the first network side device and the second network side device are different network side devices, if the first capability information indicates that cross-base station reconstruction and/or recovery are supported, the remote UE sends an RRC connection reconstruction or recovery request message to the first network side device; and if the first capability information indicates that the cross-base station reconstruction and/or recovery is not supported, the remote UE enters an RRC idle state.

2. When only the first network side device and the second network side device are determined to be of different RAT types, the first capability information indicates that the same RAT reconstruction and/or recovery is supported, and the remote UE enters an RRC idle state; and if the first capability information indicates that the same RAT reconstruction and/or recovery are not supported, the remote UE sends an RRC connection reconstruction or recovery request message to the first network side equipment.

3. When the first network side device and the second network side device are different network side devices and are different RAT types, if the first capability information indicates that cross-base station reconstruction and/or recovery is supported and the same RAT reconstruction and/or recovery is not supported, the remote UE sends an RRC connection reconstruction or recovery request message to the first network side device; and if the first capability information indicates that the cross-base station reconstruction and/or recovery is not supported and the same RAT reconstruction and/or recovery is supported, the remote UE enters an RRC idle state.

For the second capability information, the first terminal may select specific executable operations based on the supported protocol version, for example, only the remote UE supporting the R17 version enters an RRC idle state, and the remote UE supporting the subsequent evolved versions R18 and R19 etc sends an RRC connection reestablishment or recovery request message to the first network side device.

For the network indication information, the first terminal knows the capability of the network side device through the network indication information to select execution. The network indication information is sent by the first network side device through cell broadcasting and/or dedicated signaling.

Optionally, the network indication information includes one of:

first indication information indicating at least one of: whether the terminal is supported to rebuild and/or recover across base stations; whether the terminal is supported to reestablish and/or recover the same RAT;

second indication information, wherein the first indication information is used for indicating whether terminal reconstruction and/or recovery is supported.

Here, the first indication information and/or the second indication information indicate the capability of the first network-side device, which may be specific to the first terminal by the first network-side device, and may be another terminal, such as an arbitrary remote terminal.

In this way, the first terminal can select the first operation according to the first network-side device capability indicated by the first indication information and/or the second indication information. If the indicated capability of the first network side device is matched with the related information of the network side device, the remote UE sends an RRC connection reestablishment or recovery request message to the first network side device; otherwise, the execution enters an idle state.

For example, if the network side device related information includes that the first network side device is different from the second network side device, the first indication information indicates that the first network side device supports cross-base station reestablishment and/or recovery of the terminal, that is, the indicated capability of the first network side device is matched with the network side device related information, and the remote UE sends an RRC connection reestablishment or recovery request message to the first network side device; if the related information of the network side equipment comprises that the RAT types of the first network side equipment and the second network side equipment are different, the first indication information indicates that the first network side equipment supports the reestablishment and/or recovery of the terminal and the RAT, namely the indicated capability of the first network side equipment is not matched with the related information of the network side equipment, and the remote UE enters an idle state. Of course, if the other first indication information matches the related information of the network side device, the remote UE also sends an RRC connection reestablishment or recovery request message to the first network side device; if not, the remote UE enters an idle state, which is not listed here.

And the second indication information is a joint indication which does not distinguish the network side device from the RAT. If the second indication information indicates that the first network side device supports terminal reestablishment and/or recovery, the remote UE can send an RRC connection reestablishment or recovery request message to the first network side device no matter whether the network side device related information includes that the first network side device is different from the second network side device and/or the RAT types are different; if the second indication information indicates that the first network side device does not support terminal reconstruction and/or recovery, the remote UE enters an idle state no matter whether the network side device related information includes that the first network side device is different from the second network side device and/or the RAT types are different.

Further, optionally, in this embodiment, before step 201, the method further includes:

the first terminal performs a second operation, the second operation including at least one of:

releasing the PC5 entity;

establishing a Uu entity corresponding to the first signaling bearing SRB 0;

and establishing a Uu entity corresponding to the second signaling bearing SRB 1.

Here, the PC5 entity is released, that is, the PHY entity, MAC entity, adaptation layer entity, and RLC entity associated with the PC5 are all released. A Uu entity corresponding to the first signaling bearer SRB0 is established, that is, a corresponding Uu entity, such as at least one of a Uu-related PHY entity, a MAC entity, an RLC entity, and a PDCP entity, is established by using first Uu configuration information (e.g., uu-specified (specified) configuration information), and is used for receiving and transmitting, by the SRB0, for example, sending an RRC connection reestablishment or recovery request message, and receiving an RRC connection establishment response message. And establishing a Uu entity corresponding to the second signaling bearer SRB1, that is, establishing a corresponding Uu entity, such as at least one of a Uu-related PHY entity, a MAC entity, an RLC entity, and a PDCP entity, using the second Uu configuration information (e.g., uu-defined (default) configuration information), for receiving and transmitting the SRB1, for example, receiving an RRC connection reestablishment or recovery response message, and sending an RRC connection reestablishment or recovery or establishment completion message.

In addition, if the first terminal sends an RRC connection reestablishment or recovery request message to the first network side device, after the first network side device receives the RRC connection reestablishment or recovery request message, on one hand, the first network side device skips a terminal context acquisition procedure, which is the first RRC message, by judging the type of the first terminal when the type of the first terminal is the remote terminal; the first RRC message includes any one of: an RRC connection reestablishment response message; an RRC resume response message; RRC connection setup response message. Here, if the first network side device is to store the context of the first terminal (i.e., the Remote UE) and the context of the Remote UE is successfully verified, sending an RRC connection reestablishment or recovery response message to complete RRC connection reestablishment or recovery; if the first network side device does not store the context of the first terminal (i.e. the Remote UE) or the verification of the context of the Remote UE is successful, sending an RRC connection establishment response message to trigger RRC connection establishment.

After receiving the RRC connection reestablishment or recovery request message, on the other hand, the first network side device may send a terminal context acquisition request (for requesting the context of the first terminal) to the third network side device by determining whether the context of the first terminal is stored, and receive a terminal context acquisition response fed back by the third network side device, in which case the context of the first terminal is not stored, so as to return the first RRC message. Here, the third network side device is an anchor base station (which may be a second network side device or another network side device), and determines that the terminal context acquisition procedure is successful (supporting cross-base station and/or same RAT re-establishment or recovery) or failed (not supporting cross-base station and/or same RAT re-establishment or recovery) based on the terminal context and the third capability information (i.e., information indicating whether the third network side device supports cross-base station and/or same RAT re-establishment or recovery), and the terminal context acquisition response fed back after the failure carries a failure reason, and the failure reason is that cross-base station and/or same RAT re-establishment or recovery is not supported.

Further, in this embodiment, after step 201, the method further includes:

the first terminal receives configuration information sent by the first network side equipment;

and the first terminal configures the context of the first terminal according to the configuration information.

The configuration information is reconfiguration information of the first terminal.

It should be appreciated that the first network-side device may or may not support incremental configuration. Therefore, the first network-side device that does not support incremental configuration transmits configuration information including full configuration indication information, while the first network-side device that supports incremental configuration transmits configuration information not including full configuration indication information.

Optionally, therefore, one implementation is that the configuration information includes: high-level configuration information and/or bottom-level configuration information;

the step of configuring, by the first terminal, the context of the first terminal according to the configuration information includes:

releasing the bottom layer configuration in the context of the first terminal and all bearer configurations related to the PC5 RRC connection;

updating a higher layer configuration in a context of the first terminal according to the higher layer configuration information if the configuration information includes the higher layer configuration information;

and adding the bottom layer configuration in the context of the first terminal according to the bottom layer configuration information under the condition that the configuration information comprises the bottom layer configuration information.

Here, the first network side device adapted to support incremental configuration will release the underlying configuration in the context of the first terminal and all bearer configurations related to the PC5 RRC connection. Then, if the configuration information includes the high-level configuration information, the high-level configuration in the context of the first terminal can be updated by the high-level configuration information because the high-level configuration in the context of the first terminal is not released; if the configuration information includes the bottom layer configuration information, the bottom layer configuration in the context of the first terminal may be added by the bottom layer configuration information.

For example, based on configuration information including higher layer configuration information and lower layer configuration information, a remote UE may release, partially reserve, or reconfigure its configuration portion contained in the UE context. Specifically, the Remote UE entity operates: the PDCP entity corresponds to a re-establishment operation, the adaptation layer entity corresponds to a release operation, and the RLC and following entities correspond to release and add operations.

Optionally, another implementation is that the configuration information includes: full configuration indication information, and high-level full configuration information and/or bottom-level configuration information;

the step that the first terminal configures the context of the first terminal according to the configuration information comprises the following steps:

according to the full configuration indication information, releasing the high-level configuration, the bottom-level configuration and all the bearer configurations related to the PC5 RRC connection in the context of the first terminal;

adding a higher layer configuration in the context of the first terminal according to the higher layer configuration information, if the configuration information includes the higher layer configuration information;

Here, the method is applicable to the first network side device which does not support incremental configuration, and will release the upper layer configuration, the bottom layer configuration and all bearer configurations related to the PC5 RRC connection in the context of the first terminal according to the full configuration indication information. Then, if the configuration information includes higher layer configuration information, the higher layer configuration information may add higher layer configuration in the context of the first terminal; if the configuration information includes the underlying configuration information, the underlying configuration in the context of the first terminal may be added by the underlying configuration information.

For example, based on configuration information including full configuration indication information, high-level full configuration information, and low-level configuration information, a remote UE may add new configurations to all configurations included in its UE context.

Optionally, in this embodiment, the underlying configuration in the context of the first terminal includes at least one of:

PC5 physical layer PHY configuration;

MAC configuration of a PC5 media access control layer;

configuring a Radio Link Control (RLC) layer of a PC 5;

configuring a PC5 adaptation layer;

PC5 RLC channel configuration.

Here, the PC5 RLC channel configuration may be a PC5 RLC or LCH configuration.

Optionally, in this embodiment, the higher layer configuration in the context of the first terminal includes at least one of:

uu carries identification;

uu packet data convergence protocol PDCP configuration;

a Uu service data adaptation protocol SDAP configuration;

and identifying the terminal.

Here, a terminal identification (UE ID) is used for a re-establishment or recovery procedure to identify the context of the first terminal. For example, if the terminal identifier is used for the reconstruction process, the terminal identifier may be C-RNTI and PCI; if the terminal identifier is used for the recovery process, the terminal identifier may be an I-RNTI.

Optionally, in this embodiment, the bearer configuration related to the PC5 RRC connection in the context of the first terminal includes at least one of:

a first side link signaling bearer, the first side link signaling bearer being dedicated to a discovery procedure;

a second sidelink signaling bearer, said second sidelink signaling bearer being dedicated to a relay signaling flow;

a sidelink data radio bearer, the sidelink data radio bearer being dedicated to relaying data flows.

Here, the first side link signaling bearer is SL SRB4 for discovery; a second sidelink signaling bearer, namely SL SRB1/2/3if the PC5 RRC connection is setup only for relay purpose; sidelink data radio bearers are SL DRBs.

In addition, since the first terminal accesses the second network side device through the second terminal before performing the first operation, the second terminal needs to release all configurations associated with the first terminal. The release behavior of the second terminal may be indicated by the first network side device, the second network side device indicated by the first network side device, or the first terminal indicated.

Optionally, after step 201, the method further comprises:

the first terminal sends a first release indication message to the second terminal, wherein the first release indication message is used for indicating the second terminal to release all configurations corresponding to the first terminal, and the configurations are contained in the context of the second terminal.

Here, the first release indication message is sent when the remote UE selects the first cell, or when the remote UE determines to perform the first operation, or when the remote UE completes the RRC reestablishment or recovery procedure.

If the first network side device performs the release indication message, the first network side device triggers the second release indication message when receiving an RRC connection reestablishment or recovery request message sent by the first terminal, or when replying an RRC establishment message of the first terminal, or when receiving an RRC connection reestablishment or recovery completion message sent by the first terminal. Of course, the notification message may also be triggered to the second network side device at the above timing, and the second network side device sends the third release indication message.

Thus, the second terminal receives at least one of: a first release indication message sent by a first terminal; a second release indication message sent by the first network side equipment; a third release indication message sent by the second network side device; wherein, the first release indication message, the second release indication message, or the third release indication message is used to indicate the second terminal to release all configurations corresponding to the first terminal included in the context of the second terminal.

Taking the remote UE and relay UE as a sidelink communication as an example, all configurations associated with the remote UE and included in the context of the relay UE are released, including at least one of the following:

PC5 RLC channel configuration;

uu RLC channel configuration;

RLC bearing or channel mapping relation between PC5 and Uu;

an identity of the first terminal;

uu carries an identifier;

a first side link signaling bearer;

a second sidelink signaling bearer;
