Description

Data processing method and terminal equipment

Technical Field

The embodiment of the invention relates to the technical field of communication, in particular to a data processing method and terminal equipment.

Background

Introduction to contention random access procedure:

in a fifth Generation mobile communication technology (5th-Generation, 5G) system, Next Radio (NR) defines two random access procedures, i.e., a non-contention random access procedure and a contention random access procedure. Fig. 1 shows a contention random access procedure, and referring to fig. 1, the contention random access procedure includes the following steps:

step 101: the terminal device selects and transmits a preamble.

The terminal device is referred to as a User Equipment (UE).

Step 102: the UE receives a second Message (Message2, Msg2) sent by the base station, i.e. a Random Access Response (RAR), and Msg2 includes Uplink (UL) grant information.

Step 103: the UE sends a third Message (Message3, Msg3) on the UL grant included in Msg 2. It is noted here that Msg3 is transmitted through a Hybrid Automatic Repeat reQuest (HARQ) process, with the HARQ process ID fixed to 0.

During UL transmission, when the UE receives a UL grant in the RAR and the Msg3 buffer has data, the MAC PDU is obtained from the Msg 3.

Referring to fig. 2, the data packet is simultaneously placed in the HARQ buffer, and the physical layer is instructed to perform a transmission process according to the UL grant information.

Step 104: the UE receives the fourth information (Message4, Msg 4). The random access is considered successful if the UE receives a corresponding message, such as the fourth message received is scrambled by a scrambling code for the UE, or the fourth message received by the UE contains a message that is identical to the first 40 bits of the third message.

After step 103, the UE turns on a contention resolution timer. If the random access is successful in step 104, the UE will turn off the contention resolution timer. If the contention resolution timer is overtime and the UE still cannot receive the fourth message, the UE considers that the random access fails.

2) Configured Grant type 1/Configured Grant type 2 (configuration Grant type 1 and configuration Grant type 2)

Introduction about configuration Grant type 1 and configuration Grant type 2(Configured Grant type 1/Configured Grant type 2):

in NR, some UL resources are pre-configured on the network side, so that some services with high delay requirements (e.g., Ultra Reliable and Low delay Communication (urrllc)) or services with a relatively regular service format (e.g., Voice over Internet Protocol (VoIP) service) are transmitted on the configured UL resources.

The configuration authorization type 1 and the configuration authorization type 2 are two scheduling modes, the same point of the two scheduling modes is that the base station can allocate a periodic resource position in advance, and the UE can send data according to the base station and the allocated resource position. The difference between the above two scheduling modes is:

the configuration authorization type 1 is contents such as a Radio Resource Control (RRC) configuration Resource location, a Modulation Coding Scheme (MCS) mode, HARQ number, a period, and the like, does not require a physical layer activation and deactivation process, and becomes effective after RRC configuration.

The configured grant type 2 is also the RRC configured resource location, HARQ number and period, but does not configure the MCS. Meanwhile, a physical layer is required to send Downlink Control Information (DCI) to activate and deactivate resources.

The value range of the HARQ ID in the configuration authorization type 1 and the configuration authorization type 2 is 0 to N-1. Wherein, N is the number of HARQ processes which are configured by RRC and are scheduled aiming at the configuration authorization type 1 and the configuration authorization type 2. It can be seen that the HARQ process IDs of configuration grant type 1 and configuration grant type 2 also include 0.

Referring to fig. 3, fig. 3 illustrates a procedure of configuration grant type 1 and configuration grant type 2 data transmission.

Referring to fig. 4, the collision process of the Msg3 retransmission and the configuration grant includes the following moments:

time t 0: the UE receives a Random Access Responses (RAR) at time t0, where the RAR includes UL grant;

time t 1: the UE sends a new transmission of the Msg3, and the corresponding HARQ process identity identification number is 0;

time t 2: and transmitting a media access control packet data unit (configured grant MAC PDU) on the configuration grant, and if the HARQ Process Identity number (Identity, ID) is also 0(HARQ Process ID, HP ID ═ 0), overwriting the MAC PDU of the original Msg 3.

time t 3: the base station schedules the Msg3 retransmission;

time t 4: when the retransmission Msg3 is sent at time t4, since the Msg3 packet is already replaced by the configured grant MAC PDU, that is, when the Msg3 retransmits, the Msg3 MAC PDU cannot be obtained, and an error is generated.

In the prior art, when configuration authorization data is sent, if the HARQ process ID is 0, the configuration authorization MAC PDU covers the Msg3 MAC PDU in the HARQ process buffer, and the Msg3 retransmission cannot be sent.

step 601: when the HARQ process ID is the first value and there is data in the Msg3 buffer or a Contention Resolution timer (Contention Resolution timer) is running or no feedback is received that Msg3 was correctly received, the uplink grant is skipped.

In this embodiment of the present invention, optionally, the uplink grant is one or more of the following: configuration authorization; dynamically scheduling grants; other uplink grants of non-random access response.

It is understood that skipping (skip) upstream grants may also be referred to as not performing upstream grants.

It should be noted that the HARQ process is a process associated with the configuration grant, and the association relationship between the HARQ process and the configuration grant may be one-to-one, many-to-one, one-to-many, or many-to-many.

It should be noted that the contention resolution timer is running, which means that the contention resolution timer is not timed out or opened. The contention resolution timer not running means that the contention resolution timer times out or is not open.

The multiplexing and aggregation entity (multiplexing and aggregation entity) refers to an entity used by the MAC layer to generate the MAC PDU.

In an embodiment of the invention, it is determined not to fetch MAC PDUs from the MAC multiplexing and aggregation entity when the upstream grant is a configuration grant or when there is data in the Msg3 buffer, or when a contention resolution timer is running, or when no feedback is received that Msg3 was received correctly. Wherein the first value may be 0.

In the embodiment of the invention, when the uplink grant is the configuration grant, the HARQ process ID is the first value, and data exists in the Msg3 buffer or the contention resolution timer is running or does not receive the feedback that Msg3 is correctly received, the uplink grant is skipped, so that the problem that the HARQ process configured with the grant covers the Msg3 HARQ process data is solved, and the problem that the HARQ process configured with the grant covers the Msg3 HARQ process and cannot send the Msg3 retransmission if the HARQ process ID is 0 when the configuration grant data is sent is avoided.

Fig. 7 is a schematic diagram of another data processing method according to an embodiment of the present invention, and referring to fig. 7, an execution main body of the method is a terminal device, and the method includes the following specific steps:

step 701: judging whether the uplink authorization is received from the RAR; if yes, go to step 702; otherwise, go to step 704;

Step 702: judging whether data exist in the Msg3 cache; if yes, go to step 703; otherwise, go to step 704;

step 703: obtaining the MAC PDU from the Msg3 buffer, and then performing step 708;

it is understood that when the upstream grant is received from the RAR and there is data in the Msg3 buffer, the MAC PDU is retrieved from the Msg3 buffer.

Step 704: and judging whether the uplink grant is a configured (configured) grant, whether the HARQ process ID is a first value, and whether data exists in the Msg3 cache or whether a contention resolution timer is running or whether correct feedback of the Msg3 is received.

Wherein, when the uplink grant is a configuration grant, the HARQ process ID is a first value, and there is data in the Msg3 buffer or the contention resolution timer is running or no feedback that the Msg3 is correctly received is received, execute step 705;

Wherein step 707 is performed when the upstream grant is a configuration grant, or when there is data in the Msg3 cache, or when a contention resolution timer is running, or when there is no feedback correctly received by Msg 3.

Step 705: when the uplink grant is a configuration grant, the HARQ process ID is a first value, and there is data in the Msg3 buffer or no feedback that the Msg3 is correctly received is received, skip the uplink grant, and then execute

step

709 or 710.

Step 706: when the uplink grant is a configuration grant, the HARQ process ID is a first value, and there is no data in the Msg3 buffer or the contention resolution timer is not running or a feedback that Msg3 is correctly received is received, it is determined to obtain the MAC PDU from the multiplexing aggregation entity, and then step 708 is performed.

Step 707: determining not to fetch MAC PDUs from the MAC multiplexing and aggregation entity when the upstream grant is a configuration grant, or when there is data in the Msg3 buffer, or when a contention resolution timer is running, or when no feedback is received that Msg3 was received correctly.

Step 708: and transmitting the MAC PDU and the related information of the uplink authorization to the HARQ process, and executing the transmission of the MAC PDU through the HARQ process.

Step 709: HARQ processes are not cleaned when there is data in the Msg3 buffer, or when a contention resolution timer is running, or when no feedback is received that Msg3 was received correctly.

Step 710: the HARQ process is cleared when there is no data in the Msg3 buffer, or when the contention resolution timer is not running, or when feedback is received that Msg3 was received correctly.

In the embodiment of the invention, when the uplink grant is the configuration grant, the identification number of the HARQ process is the first value (for example, 0), and there is data in the Msg3 buffer or the contention resolution timer is running or does not receive the feedback that Msg3 is correctly received, the uplink grant is skipped, so that the problem that the HARQ process 0 of the configuration grant covers the Msg3 HARQ process is solved, and the problem that when the configuration grant data is sent, if the HARQ process ID is 0, the configuration grant MAC PDU covers the Msg3 MAC PDU in the HARQ process buffer, and the Msg3 retransmission cannot be sent is avoided.

Referring to fig. 8 and fig. 9, an embodiment of the present invention provides a schematic diagram of another data processing method, where an execution subject of the method is a terminal device, and the method includes the following specific steps:

step 901: receiving an uplink authorization;

wherein, the process of the current uplink authorization is a newly transmitted process; the uplink grant may be any one of a configuration grant and a grant for dynamic scheduling of a Physical Downlink Control Channel (PDCCH) received by the RAR;

step 903: judging whether data exist in the Msg3 cache; if yes, go to step 904; otherwise, go to step 905;

it can be understood that the judgment of whether there is data in the Msg3 buffer is to judge whether the Msg3 buffer is empty, and if the Msg3 buffer is not empty, there is a MAC PDU in the Msg3 buffer.

Step 904: acquiring MAC PDU from the Msg 3;

step 905: judging whether the uplink authorization is configuration authorization, whether the HARQ process ID is 0 and whether MAC PDU exists in the Msg 3;

when the uplink grant is the configuration grant, the HARQ process ID is 0, and there is a MAC PDU in the Msg3, execute step 906; when the uplink grant is a configuration grant, the HARQ process ID is 0, and there is no MAC PDU in the Msg3 buffer, execute step 907;

step 906: skipping the uplink grant;

step 907: determining to acquire the MAC PDU from the MAC multiplexing and aggregation entity.

It can be understood that when the uplink grant is received through the RAR and there is a MAC PDU in the current Msg3 buffer, the MAC PDU is obtained from the Msg3 buffer; otherwise, judging whether the uplink authorization is the configuration authorization, whether the HARQ process ID is 0 and whether data exists in the Msg3 cache; and when the HARQ process is 0 and the current Msg3 buffer has the MAC PDU, acquiring the MAC PDU from the MAC multiplexing and aggregation entity. Otherwise, it is determined that the MAC PDU will be acquired from the multiplexing and aggregation entity.

In this embodiment of the present invention, when determining not to acquire a MAC PDU from the MAC multiplexing and aggregating entity, or when determining to acquire a MAC PDU from the Msg3 or the MAC multiplexing and aggregating entity, the method flow shown in fig. 9 may further include the steps shown in fig. 10, where the specific steps are as follows:

step 1001: judging whether the MAC PDU is acquired; if yes, go to step 1002; otherwise, go to step 1003;

Step 1002: submitting the MAC PDU and the UL authorization information to an HARQ entity;

step 1003: judging whether the Msg3 cache has the MAC PDU or not; if yes, go to step 1004; otherwise, go to step 1005;

step 1004: not cleaning the HARQ cache and corresponding HARQ process;

when the MAC PDU is not acquired and the Msg3 cache is not empty, namely the MAC PDU exists in the Msg3 cache, the HARQ cache and the corresponding HARQ process are not cleaned;

step 1005: and cleaning the HARQ buffer and the corresponding HARQ process.

It can be understood that when the MAC PDU cannot be obtained and the Msg3 buffer is not empty, that is, there is a MAC PDU in the Msg3 buffer, the HARQ buffer and the corresponding HARQ process are not cleaned; and when the MAC PDU cannot be acquired but the Msg3 buffer is empty, cleaning the HARQ buffer and the corresponding HARQ process.

It can be understood that clearing the HARQ process means clearing data in the HARQ process, and turning off a timer associated with the HARQ process.

Referring to fig. 11 and fig. 12, an embodiment of the present invention provides a schematic diagram of another data processing method, where an execution subject of the method is a terminal device, and the method includes the following specific steps:

step 1102: judging whether the uplink authorization is received from the RAR; if yes, go to step 1103; otherwise, go to step 1105;

step 1103: judging whether data exist in the Msg3 cache; if yes, go to step 1104; otherwise, go to step 1105;

it can be understood that the determination of whether there is data in the Msg3 buffer is to determine whether the Msg3 buffer is empty, and if the Msg3 buffer is not empty, there is a MAC PDU in the Msg3 buffer.

Step 1104: acquiring MAC PDU from the Msg 3;

step 1105: judging whether the uplink authorization is the configuration authorization, whether the HARQ process ID is 0 and whether a contention resolution timer is running; if the uplink grant is a configuration grant, the HARQ process ID is 0, and the contention resolution timer is running, go to step 1106; if the uplink grant is the configuration grant, the HARQ process ID is 0, and the contention resolution timer is not running, step 1107 is executed;

step 1106: skipping the uplink grant;

step 1107: and acquiring the MAC PDU from the MAC multiplexing and aggregation entity.

It can be understood that when the uplink grant is received through the RAR and there is a MAC PDU in the current Msg3 buffer, it is determined to obtain the MAC PDU from the Msg3 buffer; otherwise, if the uplink authorization is the configuration authorization, judging whether the HARQ process ID is 0 and whether the contention resolution timer runs; and when the HARQ process ID is 0 and the contention resolution timer is not running, determining to acquire data from the MAC multiplexing entity. If the uplink grant is the configuration grant, the HARQ ID process ID is 0, and the contention resolution timer is running, the uplink grant is skipped.

When determining not to acquire the MAC PDU from the MAC multiplexing and aggregating entity, or when determining to acquire the MAC PDU from the MAC multiplexing and aggregating entity, the method flow shown in fig. 11 may further include the steps shown in fig. 13, and the specific steps are as follows:

Step 1302: submitting the MAC PDU and the UL authorization information to an HARQ entity;

step 1303: judging whether the competition resolving timer is not operated; if the contention resolution timer is not running, go to step 1304; if the contention resolution timer is running, go to step 1305;

it should be noted that the contention resolution timer is not running, which means that the contention resolution timer is timed out or not opened.

Step 1304: cleaning an HARQ cache and a corresponding HARQ process;

step 1305: the HARQ buffer and corresponding HARQ process are not cleaned.
