The processing method in the sending or receiving process of the embodiment of the present application may be applied to a communication device, where the communication device may be the terminal 11 or the network side device 12 in fig. 1.

In the embodiment of the present application, for a data sending end, a sending or receiving process may be understood as a sending process, and is used to send data; for the data receiving end, a sending or receiving process may be understood as a receiving process for receiving data.

For ease of understanding, some of the contents of the embodiments of the present application are described below:

1. small Data Transmission or reception (SDT).

According to the resources configured by the network side, when the UE is in an IDLE (IDLE) state or an INACTIVE (INACTIVE) state, the UE may directly send data to the network side by any of the following methods:

message (Msg) 3 of 4-step random access procedure of initial access;

MsgA of 2-step random access process of initial access;

dedicated uplink resources configured on the network side, such as: a pre-configured Physical Uplink Shared Channel (PUSCH; or, pre-allocated Uplink Resource (PUR)).

The network side can directly send data to the UE by any of the following methods:

msg4 of a 4-step random access procedure of initial access.

MsgB of a 2-step random access procedure of initial access.

And downlink feedback resources corresponding to the exclusive uplink resources configured by the network.

When the network side releases the UE from the connection state to the IDLE state or the INACTIVE state, the context configuration information of the UE is reserved. When the UE needs to transmit small data, if the system message on the network side indicates that it supports small data transmission (e.g., small data transmission of less than 10 kilobytes) is supported), the IDLE/INACTIVE UE directly receives or transmits data in the above manner, and does not enter the connected state.

2. A new two-Step Random Access Channel (2-Step RACH).

As shown in fig. 2, the 2-Step RACH may include the steps of:

step 201, the network side device configures configuration information of new two steps of random access to the terminal.

As shown in fig. 2, the configuration information may include: message (Msg) a and MsgB. After that, the terminal triggers a 2-step RACH procedure, and performs step 202.

Step 202, the terminal sends the random access request information (MsgA) to the network side device.

In a specific implementation, msgA may be sent via PUSCH. Meanwhile, the terminal may also send Physical Random Access Channel (PRACH) information to the network side. In practical applications, data (data) and a terminal identity (UE-ID) may be included in MsgA.

Step 203, the network side device sends confirmation information (MsgB) to the terminal.

And if the terminal fails to receive the MsgB, the terminal resends the MsgA. In practical applications, msgB may carry a UE-ID and an acknowledgement Indication (ACK Indication).

3. And 4, traditional step-4 random access.

The random access process of the UE comprises the following steps: a contention-based random access procedure (4-step RACH); a non-contention based random access procedure.

For the "contention-based random access procedure", the UE sends Msg1 (random access request) to the network side. After receiving the Msg1, the network side sends Msg2 (Random Access Response (RAR) message) to the UE, and the message carries Uplink Grant (Uplink Grant) information. The UE executes a Media Access Control (MAC) layer packet function to generate a MAC Protocol Data Unit (PDU) according to the Uplink Grant in the Msg2, stores the MAC PDU in the Msg3 cache, and then sends the MAC PDU in the Msg3 cache through a Hybrid Automatic Repeat Request (HARQ) process. And after receiving the Msg3, the network side sends Msg4 (such as a competition resolving identifier) to the UE. And the UE receives the Msg4 and judges whether the competition resolving is successful or not, if so, the random access process is successful, and if not, the random access process is initiated again. For the reinitiated random access process, after the UE receives the Uplink Grant in the Msg2, the UE directly takes the previously stored MAC PDU from the Msg3 cache and sends the MAC PDU through the HARQ process. And the UE empties the HARQ buffer of the Msg3 transmission in the random access process after the random access process is finished.

For a CONNECTED UE (CONNECTED UE), the Msg4 contention resolution validation may be: uplink transmission scheduled by a Cell Radio Network Temporary Identifier (Cell Radio Network Temporary Identifier) C-RNTI (Physical Downlink Control Channel, PDCCH) is newly transmitted.

For IDLE or INACTIVE UEs (IDLE/INACTIVE UEs), the Msg4 contention resolution validation may be: the "UE Contention Resolution Identity" information in the "UE Contention Resolution Identity) Media Access Control (Media Access Control, MAC) Control Unit (Control Element, CE)" received by the "UE Contention Resolution Identity" matches the first 48 bits (bit) of the "Uplink (UL) Common Control Channel (CCCH) Service Data Unit (Service Data Unit, SDU)" sent by the "UE Contention Resolution Identity" information.

The processing method in the transmitting or receiving process provided by the embodiments of the present application is described in detail below with reference to the accompanying drawings by specific embodiments and application scenarios thereof.

Referring to fig. 3, fig. 3 is a flowchart of a processing method in a transmitting or receiving process according to an embodiment of the present application. The processing method in the sending or receiving process of the embodiment of the application can be applied to communication equipment, and the communication equipment can be terminal or network side equipment.

As shown in fig. 3, the processing method in the transmitting or receiving process may include the following steps:

step 301, in case that the terminal is in an idle state or an inactive state, performs a first transmission or reception procedure.

In a specific implementation, in a scenario one in which the data sending end is a terminal, the terminal may specifically execute a first sending or receiving process: performing a first transmission process; the first sending or receiving process executed by the network side device may specifically be: a first receiving procedure is performed.

In a second scenario where the data sending end is a network side device, the terminal may specifically execute the first sending or receiving process as follows: executing an ith receiving process; the first sending or receiving process executed by the network side device may specifically be: the ith transmission process is performed.

Step 302, when the terminal performs the selection or reselection of the target cell in the first transmission or reception process, a first operation is performed.

In a specific implementation, the target cell may be a target cell selected by the terminal, or a target cell reselected by the terminal. The target cell may belong to a cell of an access network Notification Area (RNA) of the INACTIVE UE, but is not limited thereto.

In the embodiment of the present application, the first operation may include any one of:

continuing to perform the first sending or receiving process;

determining that the terminal enters an idle state;

In practical applications, the first operation may be configured by a network side device or agreed by a protocol, so that the network side device and the terminal keep consistent understanding of the first operation, and further, the reliability of data processing may be improved.

According to the processing method in the sending or receiving process, the communication equipment executes a first sending or receiving process under the condition that the terminal is in an idle state or an inactive state; when the terminal selects or reselects a target cell in the first transmission or reception process, performing a first operation, where the first operation includes any one of: continuing to perform the first sending or receiving process; abandoning the execution of the first sending or receiving process and executing a second sending or receiving process; abandoning the execution of the first sending or receiving process, and reserving the context configuration information of the terminal; determining that the terminal initiates a connection recovery area updating process; determining that the terminal enters an idle state; and giving up to execute the first sending or receiving process, and deleting the context configuration information of the terminal, wherein the communication equipment is the terminal or network side equipment. Therefore, the embodiment of the application specifies the processing behavior of the communication device under the condition that the terminal performs the selection or reselection of the target cell in the first sending or receiving process, so that the reliability of data processing can be improved.

In this embodiment of the present application, when the terminal performs selection or reselection of the target cell in the first sending or receiving process, the communication device may directly perform the first operation, or may perform the first operation according to a target determination result.

Optionally, the target determination result may include at least one of the following:

whether the target cell supports a first judgment result of a target sending or receiving process;

whether the target cell supports the second judgment result that the terminal recovers the context configuration information of the terminal through a connection recovery process or not;

a third determination result of whether the target cell supports the connection recovery function.

In particular implementation, the context configuration information of the terminal may include, but is not limited to, PDCP configuration and security context. The function of the target cell for supporting connection recovery may specifically be implemented as follows: the target cell supports the RNA function, which is indicated in a System Information Block (SIB) 1, but is not limited thereto.

The first and second transmitting or receiving processes belong to the target transmitting or receiving process. That is, the first and second transmission or reception processes may be understood as: target transmission or reception processes performed by the communication device at different times.

In this embodiment of the present application, the target sending or receiving process may be a sending or receiving process that can be executed by any idle terminal or inactive terminal, which is not limited in this embodiment of the present application. In the process of target transmission or reception, the terminal and the network side device may directly perform data transmission or reception, such as: in the scenario one, the terminal may directly send the data to the network side device; in the second scenario, the network side device may directly send data to the terminal, and therefore, the target sending or receiving process may also be referred to as a direct sending or receiving process, or a direct data transceiving process. Alternatively, the target sending or receiving procedure may be the aforementioned SDT procedure, but is not limited thereto.

Optionally, the target sending or receiving process may include any one of the following:

a process of sending or receiving a message Msg3 in the 4-step random access process;

through the MsgA sending or receiving process in the 2-step random access process;

a process of transmitting or receiving through dedicated uplink resources of the terminal;

sending or receiving through Msg4 in the 4-step random access process;

through the MsgB sending or receiving process in the 2-step random access process;

and sending or receiving the downlink resource corresponding to the uplink resource exclusive to the terminal.

The concrete description is as follows:

for the terminal in scenario one above, the target sending or receiving process may include any one of the following: a process of sending data through a message Msg3 in the 4-step random access process; a process of sending data through MsgA in the 2-step random access process; and sending data through the exclusive uplink resource of the terminal. For the network side device in scenario one above, the target sending or receiving process may include any one of the following: a process of receiving data through a message Msg3 in the 4-step random access process; a process of receiving data through the MsgA in the 2-step random access process; and receiving data through the exclusive uplink resource of the terminal.

For the terminal in scenario two above, the target sending or receiving process may include any one of the following: a process of receiving data through the Msg4 in the 4-step random access process; a process of receiving data through the MsgB in the 2-step random access process; and receiving data through a downlink resource corresponding to the uplink resource exclusive to the terminal. For the network side device in the second scenario, the target sending or receiving process may include any one of the following: a process of sending data through the Msg4 in the 4-step random access process; a process of sending data through the MsgB in the 2-step random access process; and sending data through the downlink resource corresponding to the uplink resource exclusive to the terminal.

It should be noted that, in practical applications, the types of the first sending or receiving process and the second sending or receiving process may be the same or different. Such as: in a case that the first sending or receiving process is a process of sending or receiving through the message Msg3 in a 4-step random access process, in an embodiment, the second sending or receiving process may also be a process of sending or receiving through the message Msg3 in a 4-step random access process; in another embodiment, the second sending or receiving process may be a MsgA sending or receiving process in a 2-step random access process.

In addition, the data transmitted or received by the first transmission or reception process and the second transmission or reception process may be the same or different. Optionally, in a case that the first sending or receiving process is used to send or receive a first data group, the first sending or receiving process is used to send or receive a second data group, and the second data group may include target data, where the target data is data that is unsuccessfully sent or unsuccessfully received in the first sending or receiving process in data included in the first data group, or the data included in the second data group may be different from the data included in the first data group.

To facilitate understanding of the target data, examples are illustrated as follows:

if the communication device transmits or receives 1, data 2 and data 3 through the first transmission or reception process, and if the communication device has successfully completed transmitting or receiving data 1 through the first transmission or reception process before the terminal performs selection or reselection of the target cell in the first transmission or reception process, the target data includes data 2 and data 3.

Further, in a case where the second data group includes the target data, the communication device continues to perform the first transmission or reception procedure, or performs the second transmission or reception procedure, which may include any one of:

reconstructing the target data in the first sending or receiving process and then sending or receiving the reconstructed target data;

and retransmitting or receiving the target data in the first transmission or reception process.

In the embodiment of transmitting or receiving the reconstructed target data in the first transmission or reception process, the communication device may transmit or receive the reconstructed target data in the first transmission or reception process. Taking the Data sending end as the UE, the MAC layer of the UE may reconstruct the cached target Data to generate a new MAC Protocol Data Unit (PDU) and send the PDU. In this way, the target cell can identify the target data after reconstruction or retransmission or reception, so that the reliability of transmission or reception of the target data can be improved.

In retransmitting or receiving the target data in the first transmission or reception process, the communication device retransmits or receives the target data in the first transmission or reception process. Taking a Data sending end as the UE as an example, a Packet Data Convergence Protocol (PDCP) layer of the UE resends PDCP SDUs or PDUs of the target Data. Thus, the target cell can be transmitted or received on the transmission or reception resource of the target data, and the reliability of transmission or reception of the target data can be improved.

The following describes the communication device specifically executing the first operation according to the target determination result:

1) The first operation includes continuing to perform the first transmit or receive procedure.

In this case, even in the case where the terminal has performed the selection or reselection of the target cell in the first transmission or reception procedure, the communication device may continue to perform the first transmission or reception procedure, that is, the behavior of the terminal having performed the selection of the target cell in the first transmission or reception procedure does not affect the performance of the first transmission or reception procedure by the communication device.

In this embodiment of the application, optionally, the continuing to perform the first sending or receiving process includes any one of:

during the running period of a counter or a timer corresponding to the first sending or receiving process, reconstructing the target data in the first sending or receiving process and then sending or receiving the reconstructed target data;

In this alternative embodiment, the communication device may, in the above case, give up performing the first sending or receiving procedure and retain the context configuration information of the terminal, but is not limited thereto.

4) The first operation includes determining that the terminal initiates a connection recovery area update procedure.

In this case, the communication device may determine that the terminal initiates the connection recovery area update procedure when the terminal performs the selection or reselection of the target cell in the first transmission or reception procedure. In specific implementation, after determining to initiate the update process of the connection recovery area, the terminal may initiate the update process of the connection recovery area, for example: the UE sends a Radio Resource Control (RRC) Resume Request (Resume Request) message indicating an RNA region update.

For ease of understanding, examples are illustrated below:

example one

In a first embodiment, a processing method of a sending or receiving process may include the following steps:

step one, UE initiates a direct data transceiving process.

Wherein, the "direct data transceiving process" includes any one of:

4, sending data in Msg3 in the random access process;

2, sending data in MsgA in the random access process;

data is sent in exclusive uplink PUSCH resources configured by a network;

receiving data in Msg4 in the 4-step random access process;

2, receiving data in MsgB in the random access process;

and receiving data in the downlink resource corresponding to the exclusive uplink resource configured by the network.

Such as: after the UE sends Data Radio Bearer (DRB) Data or Signaling Radio Bearer (SRB) request message in dedicated PUSCH resource, the UE obtains Physical Downlink Shared Channel (PDSCH) scheduling information by monitoring specific UE identifier (e.g., x-RNTI) in Physical Downlink Control Channel (PDCCH) resource corresponding to the PUSCH, and the PDSCH includes Downlink received Data of DRB of the UE.

Step two, in the process of the direct data transceiving process, if the UE performs cell selection or reselection, the processing behavior of the UE includes any one of the following:

method 1.1: if the selected (or reselected) target cell also supports the "direct data transceiving procedure" of the UE, the UE continues the "direct data transceiving procedure".

Method 1.2: if the selected (or reselected) target cell also supports the "direct data transceiving process" of the UE, the UE abandons the "direct data transceiving process" and starts a new "direct data transceiving process".

Method 1.3: if the selected (or reselected) target cell also supports the UE's "direct data transceiving process", the UE abandons the "direct data transceiving process", and the UE retains its stored context configuration information (e.g., PDCP configuration and security context.)

Method 1.4: if the selected (or reselected) target cell also supports the "direct data transceiving process" of the UE, the UE initiates a connection recovery area update procedure.

For example, the UE sends a rrcresemequest message indicating an RNA region Update (e.g., RNA-Update).

Method 2.1: if the selected (or reselected) target cell does not support the "direct data transceiving process" of the UE, the UE enters an IDLE state.

If so, the UE aborts the "direct data transceiving process" and enters the IDLE state.

Method 2.2: if the selected (or reselected) target cell does not support the "direct data transceiving process" of the UE, the UE enters an IDLE state and then re-initiates the connection establishment process.

If so, the UE aborts the "direct data transceiving process" and enters the IDLE state. The IDLE UE then initiates a connection establishment procedure.

Method 2.3.1: if the selected (or reselected) target cell does not support the "direct data transceiving process" of the UE, but supports the UE to restore its stored context through the connection restoration process, the UE aborts the "direct data transceiving process" and the UE retains its stored context configuration information.

Method 2.3.2: if the selected (or reselected) target cell does not support the "direct data transceiving process" of the UE, but supports the UE to restore its stored context through the connection restoration process, the UE initiates the connection restoration area update process.

Method 2.4: if the selected (or reselected) target cell does not support the "direct data transceiving process" of the UE, nor does the UE support restoring its stored context through the connection restoration process, the UE enters the IDLE state.

Method 2.5: if the selected (or reselected) target cell does not support the "direct data transceiving process" of the UE, nor support the UE to restore its stored context through the connection restoration process, the UE enters the IDLE state and then re-initiates the connection establishment process.

Method 2.6: if the selected (or reselected) target cell does not support the "direct data transceiving process" of the UE, but supports the connection recovery function (e.g., the cell supports the RNA function as indicated in SIB 1), the UE initiates the connection recovery area update procedure.

Method 3.1: the UE enters the IDLE state.

Method 3.2: the UE enters the IDLE state and then re-initiates the connection establishment procedure.

Method 3.3: the UE initiates a connection recovery area update procedure.

Method 3.4: if the selected (or reselected) target cell supports the connection recovery function, the UE initiates a connection recovery area update procedure.

Method 3.5: if the selected (or reselected) target cell does not support the connection recovery function, the UE enters an IDLE state.

Method 3.6: if the selected (or reselected) target cell does not support the connection recovery function, the UE enters an IDLE state and then reinitiates the connection establishment procedure.

Method 4.1.1: if the selected (or reselected) target cell supports the UE to restore the stored context through the connection restoration process, the UE abandons the direct data transceiving process, and the UE retains the stored context configuration information.

Method 4.1.2: if the selected (or reselected) target cell supports the UE to restore its stored context through a connection restoration procedure, the UE initiates a connection restoration area update procedure.

Method 4.2: if the selected (or reselected) target cell does not support the UE to restore its stored context through a connection restoration procedure, the UE enters an IDLE state.

Method 4.3: if the selected (or reselected) target cell does not support the UE to restore its stored context through the connection restoration process, the UE enters an IDLE state and then re-initiates the connection establishment process.

The target cell may belong to a cell of RNA of INACTIVE UE.

Wherein, the condition for the UE to judge and end the direct data transceiving process comprises any one of the following items:

receiving specific control information of a network side;

data to be transmitted has already been transmitted (e.g., DRB-1 has 1 packet transmitted, which has already been transmitted);

data to be received has been received (e.g., DRB-1 has received a packet that has been received)

The UE proactively abandons the connection establishment procedure (e.g., higher layer applications of the UE do not proactively abandon the connection establishment procedure).

Wherein the "specific control information" includes any one of:

connection recovery messages (e.g., RRCResume);

a connection setup message (e.g., RRCSetup);

a connection release message (e.g., RRCRelease);

a connection rejection message (e.g., RRCRejection).

Wherein, the meaning of "data has been transmitted" includes any one of the following:

data is sent for the first time;

data is successfully transmitted (e.g., feedback information of successful reception on the network side is received).

Wherein the meaning of "data has been received" includes any one of:

the first reception of data (e.g., the first reception of data for HARQ process 1, but the data for HARQ process 1 is not necessarily decoded successfully);

the data is successfully received (e.g., the content of the data channel PDSCH transmitted by the network side is received and successfully decoded).

For method 1.1, the act of continuing the "direct data transceiving process" further comprises any of:

the UE reconstructs the data in the "direct data transceiving process" and then transmits the reconstructed data, for example: and the MAC layer of the UE reconstructs the cached data in the direct data transceiving process to generate a new MAC PDU and then transmits the new MAC PDU.

The UE retransmits the data in the "direct data transceiving process", for example: the PDCP layer of the UE retransmits the PDCP SDU or PDU in the "direct data transceiving procedure".

For method 1.2, the act of the ue initiating a new "direct data transceiving procedure" further comprises any of:

the UE reconstructs the data in the previous "direct data transceiving process" and then transmits the reconstructed data, for example: and the MAC layer of the UE reconstructs the cached data in the previous direct data transceiving process to generate a new MAC PDU, and then sends the new MAC PDU.

The UE retransmits the data in the previous "direct data transceiving process" as follows: the PDCP layer of the UE retransmits the PDCP SDU or PDU in the previous "direct data transceiving procedure".

In the embodiment of the present application, in the process of performing direct data transceiving, if cell selection or reselection occurs, the UE performs a specific process according to a network configuration or a protocol agreed method. That is to say, with the processing method in the sending or receiving process according to the embodiment of the present application, if cell selection or reselection occurs during direct data transceiving of the UE, specific processing may be performed according to a method agreed by a network configuration or a protocol, so that the network side and the UE side can keep the understanding of the configuration of the UE consistent.
