Description

Random access method, terminal and network equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a random access method, a terminal, and a network device.

Background

As the 5Generation (5G) system standard evolves, the physical layer determines to introduce a new Radio Network Temporary Identity (RNTI) for a User Equipment (UE, also called a terminal) to indicate a new Modulation and Coding Scheme (MCS) table, which is generally used for Ultra-reliable Ultra-low-latency communications (URLLC), but not limited to URLLC.

For contention-based random access, the whole process comprises 4 steps:

step 1, message one, namely Msg 1: sending a preamble

The base station is responsible for configuring the preamble and Physical Random Access Channel (PRACH) resources of resources for transmitting the preamble, and notifying a terminal residing in a cell of a configuration result through a system message. The terminal sends a lead code, and the base station estimates the transmission delay of the terminal according to the lead code to realize uplink synchronization.

Step 2, message two, namely Msg 2: random Access Response (RAR)

The network side sends a timing advance command to adjust the sending time of the terminal based on the transmission delay estimated in the first step. In addition to establishing uplink synchronization, the step also allocates uplink resources used in the third step in the re-random access process to the terminal.

Step 3, message three, namely Msg 3: first scheduling transmission

The mobile terminal identification information is sent to the network side through an Uplink Shared Channel (UL-SCH) in a manner similar to sending ordinary Uplink data, and the specific content in the message depends on the state of the terminal, especially whether the network already knows the existence of the terminal before.

Step 4, message four, namely Msg 4: contention resolution

The last step, which includes the contention resolution message sent by the network side to the terminals on the Downlink Shared Channel (DL-SCH), resolves the contention and collision caused by multiple terminals trying to access the system using the same random access resource.

Msg3 is transmitted on the UL-SCH using Hybrid Automatic repeat request (HARQ). The Msg3 needs to contain an important message: a unique flag per UE. This flag will be used for conflict resolution in step 4.

For a UE in radio resource control CONNECTED (RRC _ CONNECTED) state, the only flag is cell RNTI (C-RNTI).

For a UE in non-RRC _ CONNECTED state, a unique UE identity (S-TMSI or a random number) from the core network will be used as its identity. In this case, the base station needs to communicate with the core network first to respond to the Msg 3.

When the UE is in the RRC _ CONNECTED state but does not have uplink synchronization, the UE has the C-RNTI of the UE, in the Msg3 of the random Access process, the UE can tell the base station the C-RNTI of the UE through a Media Access Control (MAC) Control unit (CE), and the base station uses the C-RNTI to solve the conflict in step 4.

In the existing random access procedure, for the UE in the RRC _ CONNECTED state, the only mark is C-RNTI. The network can only be informed via the RNTI which UE is performing random access. The network cannot be informed that the UE is due to which service or which logical channel triggered the random access procedure. Compared with the low-priority service, the high-priority service cannot inform the network earlier to acquire more appropriate resources; however, the conventional transmission method of the message two is only used for performing random access response, and the UE cannot understand the intention of the base station according to the message two, so that the priority processing of the high-priority service cannot be guaranteed.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

The invention provides a random access method, a terminal and network equipment, aiming at the problem that the prior random access message two or message three sending mode can not ensure the early processing of high priority service for a RRC connection state terminal.

As shown in fig. 1, an embodiment of the present invention provides a random access method, which is applied to a terminal, and includes:

step 101, acquiring a trigger reason of a random access process;

step 102, if the trigger reason is a preset trigger reason, sending a message III containing a first radio network temporary identifier RNTI to network equipment;

it should be noted that the message three including the first RNTI is used for indicating the preset state of the terminal;

the preset state comprises: at least one of a service with a first preset priority, a logical channel with a second preset priority and a logical channel group with a third preset priority;

it should be noted that, the first preset priority, the second preset priority and the third preset priority all refer to a priority higher than a certain priority level, for example, the first preset priority traffic refers to a high priority traffic (e.g., URLLC), the second preset priority logical channel refers to a high priority logical channel (e.g., URLLC), and the third preset priority logical channel group refers to a high priority logical channel group (e.g., URLLC).

It should be noted that the first RNTI is a new RNTI indicating that a new MCS table, which is generally used for URLLC service, is used, and the new RNTI is also referred to as MCS-C-RNTI.

It should be noted that, when the network device has configured a new RNTI for the terminal, the terminal may send a message three including the new RNTI to the network device only when the trigger reason is the preset trigger reason.

Further, the preset trigger reason includes at least one of the following information:

a1, switching terminals with preset states;

for example, a terminal having a high-priority service, a high-priority logical channel, or a high-priority logical channel group undergoes cell switching, beam switching, or the like.

A2, the terminal with the preset state recovers the beam failure;

for example, a terminal having a high-priority service, a high-priority logical channel, or a high-priority logical channel group performs beam failure recovery.

A3, performing connection reestablishment on a terminal in a preset state;

for example, a terminal having a high-priority service, a high-priority logical channel, or a high-priority logical channel group performs connection reestablishment of a cell.

A4, the terminals with preset states are not synchronized in uplink;

for example, there is uplink asynchronization in a terminal having a high priority service, a high priority logical channel, or a high priority logical channel group.

A5, the uplink data of the terminal with the preset state arrives;

for example, a terminal having a high-priority service, a high-priority logical channel, or a high-priority logical channel group determines that uplink data of the network device has been transmitted.

When the trigger reason of the random access process of the terminal meets any one of the preset trigger reasons, the terminal is triggered to send a message III containing a new RNTI to the network equipment, so that the terminal can send the message III according to the service state of the terminal, the logic channel state or the logic channel group state, and the network equipment can be ensured to process the service of the terminal preferentially.

It should be further noted that, because the terminal sends the third message to the network device, indicating that the terminal performs the competitive random access, before sending the third message, the terminal and the network device need to transmit the second message first, so that the network device can inform the terminal of its own processing intention (or resource scheduling condition), before step 102, the random access method further includes:

receiving a second message sent by the network equipment in a preset mode;

wherein, the preset mode comprises: adopting a preset Downlink Control Information (DCI) format and/or adopting a preset Cyclic Redundancy Check (CRC) mode;

it should be noted that the preset DCI format refers to a new DCI format, that is, is different from the existing DCI format; the preset CRC scheme is a new CRC scheme, which is different from the existing CRC scheme, for example, the new CRC scheme is a preset CRC mask scheme, and the preset CRC mask scheme is a scheme in which bits not scrambled by the RNTI (i.e., a mask not scrambled by the RNTI) in the existing CRC are used for CRC.

It should be noted that the message two in the preset manner is used for responding to the random access message.

A second message sent by the network device in a preset manner, where the second message sent by the preset manner is used to indicate a resource scheduling condition of the network, for example, the network supports scheduling of fewer resources; the terminal obtains new scheduling information, for example, a new MCS table, or uses a new scheduling transmission mode, or the scheduling information is applied to a certain service or a certain specific logical channel, or indicates a new MAC Random Access Response (RAR) load (payload), etc., by analyzing the second message sent in the preset mode, so that the terminal performs a subsequent service processing process according to the new scheduling information.

As shown in fig. 2, an embodiment of the present invention provides a random access method, applied to a network device, including:

step 201, receiving a third message which is sent by a terminal and contains a first Radio Network Temporary Identifier (RNTI);

the message III is used for indicating the preset state of the terminal;

Specifically, the preset trigger reason includes at least one of the following information:

switching the terminals with the preset states;

the terminal with the preset state recovers the beam failure;

carrying out connection reconstruction on the terminal with the preset state;

the uplink of the terminal in the preset state is asynchronous;

and the uplink data of the terminal with the preset state arrives.

Further, before the third message including the first radio network temporary identity RNTI sent by the receiving terminal, the method further includes:

sending a second message to the terminal in a preset mode;

and the second message is used for responding to the random access message.

It should be noted that all the descriptions regarding the network device side in the previous embodiment are applicable to the embodiment of the random access method applied to the network device side, and the same technical effects can be achieved.

As shown in fig. 3, an embodiment of the present invention provides a random access method, applied to a terminal, including:

step 301, receiving a second message sent by the network device in a preset mode;

It should be noted that the second message is used for responding to the random access message.

Further, the message two sent in the preset mode is also used for indicating that the random access process is successfully completed.

It should be noted that, when the message two sent in the preset manner is used to indicate that the random access procedure is successfully completed, the random access corresponds to non-contention random access. In non-contention random access, if the terminal successfully receives the message two, the random access process is considered to be successfully completed.

In the implementation of the invention, the second message is sent in a preset mode, so that the network equipment informs the terminal of the resource scheduling condition of the network equipment in the random access process, so as to assist the terminal to perform subsequent services according to the specific conditions of the network side in the subsequent communication process, and ensure that the services with specific priorities are processed as early as possible.

As shown in fig. 4, an embodiment of the present invention provides a random access method, applied to a network device, including:

step 401, sending a message two to a terminal by adopting a preset mode;

and the second message is used for responding to the random access message.

Further, the second message is also used for indicating that the random access procedure is successfully completed.

The following exemplifies a specific application scenario of the above embodiment from a practical application process.

Case one, for non-contention random access procedure

Method one, adopting new method to send message two

In this way, the specific implementation process of random access is as follows:

the terminal sends a message I in the random access process to the network equipment;

after receiving the message one, the network device transmits a message two by using a new DCI format (or a new CRC scheme).

Case two, random access procedure for contention

The method I is used for sending a message II in a new mode, and the method III is used for sending a message III in the existing mode

after receiving the message I, the network equipment transmits a message II by adopting a new DCI format (or a new CRC mode);

after receiving the second message, the terminal sends a third message in the existing mode, namely C-RNTI is carried in the third message;

and after receiving the third message, the network equipment feeds back a fourth message to the terminal.

The second mode is adopted to send the second message, and the third message is sent in a new mode

after receiving the message I, the network equipment sends a message II in the existing mode;

after receiving the second message, the terminal sends a third message carrying a new RNTI;

and after receiving the message III carrying the new RNTI, the network equipment feeds back a message IV to the terminal.

A third mode is adopted to send the second message, and a third mode is adopted to send the third message

As shown in fig. 5, an embodiment of the present invention provides a terminal 500, including:

an obtaining module 501, configured to obtain a trigger reason of a random access procedure;

a first sending module 502, configured to send a third message including a first radio network temporary identifier RNTI to a network device if the trigger reason is a preset trigger reason;

switching the terminals with the preset states;

the terminal with the preset state recovers the beam failure;

carrying out connection reconstruction on the terminal with the preset state;

the uplink of the terminal in the preset state is asynchronous;

and the uplink data of the terminal with the preset state arrives.

the first receiving module is used for receiving a second message sent by the network equipment in a preset mode;

and the second message is used for responding to the random access message.
