Description

Information transmission method, terminal and network device

Cross-reference to related applications

The present application claims priority to Chinese Patent Application No. 20181000864, filed on Jan. 4, s.

Technical field

The present disclosure relates to the field of communications technologies, and in particular, to an information transmission method, a terminal, and a network device.

Background technique

The Carrier Aggregation (CA) technology is introduced in the Long Term Evolution (LTE) system. The carrier technology is a user equipment (User Equipment, UE, also called terminal), which communicates through multiple cells and networks. One of the cells is a primary cell (PCell), and the other cells are secondary cells (SCell). The secondary cell has an active and deactivated state; the primary cell has no deactivated state and remains active.

When the base station adds one or more secondary cells through a Radio Resource Control (RRC) Connection Reconfiguration message, the initial state of the secondary cells is deactivated; in the handover scenario, the target base station passes the handover command. The Handover Command sends the secondary cell configuration information to the source base station. When the source base station forwards the message to the terminal through the RRC connection reconfiguration message, all the secondary cells are deactivated.

At present, the LTE project plans to introduce a fast carrier activation deactivation method, wherein one method is: the initial state of the secondary cell is configurable, that is, configured as an active state or a deactivated state, and the conclusion of the 3GPP conference is as follows: in Rel-15 Support configuration SCell directly in activated/deactivated state in Rel-15.

In addition, a new state is introduced for the secondary cell, that is, a New SCell fast activation state, which is a state between the active state and the deactivated state. The characteristics of the new state, the conclusions of the 3GPP meeting are as follows:

Do not introduce L1 signaling (Not introduce L1signalling);

Only period CQI report based on CRS;

The PDCCH (without PDCCH monitoring) is not monitored.

At present, both LTE and New Radio (NR) need to achieve multiple purposes by supporting a random access procedure; and the purpose of random access discussed by NR may include the following:

A1, supporting an initial RRC idle (idle) terminal connected to the network;

A2, RRC reconstruction;

A3, switching;

A4, the downlink data arrives but the uplink is out of step;

A5, the uplink data reaches but the uplink is out of step;

A6. The terminal moves from an inactive state to an active state.

A7. Support uplink synchronization acquisition of the secondary cell.

It should be noted that the current Random Access Channel (RACH) process is divided into a competitive random access and a non-competitive random access process, and both the contention of the random access and the content of the non-competitive random access are both Is to send RAR.

At present, for the secondary cell in the new state, it is considered that the RACH is not required. When the secondary cell is in the new state, if the secondary cell is not allowed to transmit the preamble, the uplink synchronization of the terminal may be inaccurate at this time, so When the network activates the secondary cell, it is still necessary to perform uplink RACH to obtain Timing Advance (TA) synchronization after the secondary cell is activated, which delays the use of the secondary cell.

In the future 5th generation (5Generation, 5G) mobile communication system, in order to achieve the downlink transmission rate of 20Gbps and the uplink transmission rate of 10Gbps, high-frequency communication and large-scale antenna technology will be introduced. High-frequency communication can provide a wider system bandwidth, and the antenna size can be smaller, which is more conducive to large-scale antenna deployment in base stations and terminals. High-frequency communication has the disadvantages of large path loss, easy interference, and weak link. Large-scale antenna technology can provide large antenna gain. Therefore, the combination of high-frequency communication and large-scale antenna is the future 5G mobile communication system. The inevitable trend. However, the use of large-scale antenna technology cannot solve all the problems of high-frequency communication, such as link fragility. When occlusion is encountered in high-frequency communication, the beam failure recovery mechanism can quickly switch the beam, switch the communication link from the poorer beam to the better beam, avoid the failure of the wireless link, and effectively improve the robustness of the link.

The 3GPP (3rd Generation Partnership Project) RAN (Radio Access Network) 1 agrees to introduce a terminal beam failure recovery request mechanism.

Summary of the invention

Detailed ways

The present disclosure will be described in detail below with reference to the drawings and specific embodiments.

The related art of the present disclosure will be briefly described below.

On the basis of the carrier aggregation technology, the terminal maintains a secondary cell deactivation timer (SCell Deactivation Timer) for each secondary cell. When the secondary cell enters an active state, the terminal starts a corresponding secondary cell deactivation timer, and the secondary cell is activated. The terminal does not receive the data or physical downlink control channel (PDCCH) message on the corresponding secondary cell within the time specified by the deactivation timer, and the terminal automatically deactivates the secondary cell.

The activation/deactivation mechanism of the secondary cell is implemented based on a combination of Activation/Deactivation Media Access Control (MAC) Control Element and Deactivation Timer.

Under the above premise, since the delay from the deactivated state to the active state is large, in order to reduce the delay, a new state is introduced, that is, a new fast SCell activation state/auxiliary SCell new state, in this new state, agree to the following:

L1 signaling is not introduced for state transitions;

Periodic Channel Quality Indicator (CQI) reporting is performed based on a Cell-Specific Reference Signal (CRS, also referred to as a common reference signal);

The PDCCH is not monitored.

At the same time, the transition between the new state and the active and deactivated states can be controlled by the MAC CE.

The Bandwidth Part (BWP) is a new concept introduced in 5G NR. From the perspective of the terminal, each carrier corresponds to an independent cell (primary cell or secondary cell). BWP means that under each carrier of large bandwidth, the carrier of the large bandwidth can be divided into several parts, each part is a smaller bandwidth part, and for the connected state terminal, one or more terminals can be allocated (activated) to the terminal. The BWP performs data and control information transmission. As shown in FIG. 1, FIG. 1 shows a transmission diagram of only one BWP activation at a time in the current cell. When the secondary cell is configured to be in an active state, the associated BWP is activated. When the secondary cell is configured to be deactivated, the associated BWP is deactivated, wherein the dotted box in Figure 1 represents the activated BWP; and the solid line box indicates that the BWP is configured, but the BWP is not activated. .

Currently, the RACH process is divided into a competitive random access and a non-competitive random access process. The competitive random access process is divided into four steps, as shown in FIG. 2, including:

Step 21, the terminal sends a random access preamble (Random Access Preamble), that is, Message1;

Step 22: The base station feeds back a random access response (RAR), that is, Message2;

Step 23, the terminal sends a contention resolution request to the base station, that is, Message3;

In step 24, the terminal receives the contention resolution result of the base station, that is, Message4.

The non-competitive random access process is divided into 2 steps, as shown in Figure 3, including:

Step 31, the terminal sends a random access preamble, that is, Message1;

Step 32, the base station feeds back a random access response, that is, Message2;

It should be noted that, before step 21 and step 31, the base station sends a random access preamble assignment (RA Preamble assignment) message to the terminal.

As shown in Figure 4, the current RAR supports several formats, but currently the RAR format is separated by the Message1 packet in the RACH, that is, the preamble packet, that is, the RAR format of a group or a preamble is the same. The timing advance command is included in the RAR, and the terminal acquires the timing advance through the RAR.

For the BWP, the new state may be similar to the secondary cell. In the embodiment of the present disclosure, when the secondary cell or the bandwidth part is in a new state, if the secondary cell or the bandwidth part is not allowed to send the preamble, the terminal Uplink synchronization may be inaccurate. If the secondary cell or the bandwidth part is activated, the uplink RACH needs to be used to obtain tracking area synchronization after the secondary cell or the bandwidth part is activated. This may delay the use of the secondary cell or the bandwidth part. The problem is as follows. Specifically, as shown in FIG. 5, the information transmission method of the embodiment of the present disclosure is applied to a terminal, including:

Step 501: When the state of the configured target object is the first state, the terminal determines whether there is a trigger condition for information transmission.

It should be noted that the target object includes: one of a secondary cell and a bandwidth part;

Wherein the first state is a deactivated state; or

The first state is a new state of the target object (ie, corresponding to the new state described above), in which the terminal does not monitor the PDCCH on the target object, and performs at least one of the following cases :

Perform periodic channel quality indication reporting;

Sending a sounding reference signal;

Capable of receiving data on a physical downlink shared channel;

It is capable of transmitting data on a physical uplink shared channel.

Step 502: If there is a trigger condition for information transmission, transmitting information corresponding to the trigger condition to the network device;

It should be noted that the triggering condition includes: monitoring a physical downlink control channel PDCCH indicating that the terminal performs uplink transmission on the target object, or configuring a beam presence beam failure of the target object. In this process, when the state of the configured target object is the first state, the terminal can implement the monitoring of the PDCCH, that is, whether the presence of the indication terminal is performed on the target object for uplink transmission (the uplink transmission refers to the terminal sending). The PDCCH of the information to the network device transmits the information corresponding to the PDCCH when the PDCCH is monitored. For example, when the PDCCH indicates that the terminal needs to send the preamble on the target object, the terminal performs the target object. The preamble is transmitted, and then the random access process is performed; when the state of the configured target object is the first state, the terminal can implement the detection of the beam, that is, whether the beam of the target object is detected to have a beam failure, and if a beam change occurs. And transmitting information corresponding to the beam failure.

Step 503: Receive response information fed back by the network device.

In this step, the network device feeds back the response information of the response according to the information sent by the terminal to the terminal, and the terminal receives the response information and performs a subsequent communication process.

The embodiments of the present disclosure are specifically described below from the perspective of different trigger conditions.

1. When the trigger condition includes monitoring the PDCCH indicating that the terminal performs uplink transmission on the target object.

In this case, the specific implementation of the step 502 is: sending a random access preamble to the network device on the target object; further, the specific implementation manner of step 503 is: receiving the sending by the network device Random Access Response (RAR).

Generally, the random access response carries the uplink authorization information. When the terminal receives the random access response, the terminal may consider the uplink authorization information or the authorization information. The specific implementation manner is as follows:

1. When the terminal does not consider the uplink authorization information, when the terminal receives the random access response, it may perform at least one of the following processes from two situations:

A1, ignoring the uplink grant information in the random access response;

A2. Determine that the value of the uplink grant information allocation in the random access response is zero.

A3. Perform TA adjustment according to timing advance (TA) related information in the random access response.

When the terminal does not consider the uplink authorization information, at this time, only the synchronization of the TA information is performed, and the state of the target object configured by the terminal does not change.

2. When the terminal considers the uplink grant information, when the terminal receives the random access response, the following process is performed:

And sending uplink data information to the network device according to the uplink grant information in the random access response.

Further, the network device side receives the uplink data information, and performs a subsequent communication process according to the uplink data information.

When the terminal grants the uplink authorization information, the terminal needs to perform subsequent information transmission. At this time, the state of the target object configured by the terminal needs to be adjusted to implement information transmission. Specifically, the terminal sets the state of the target object by A state is adjusted to the second state. It should be noted that the second state is an active state, that is, the terminal should adjust the state of the configured target object from the new state to the active state to indicate that information can be performed on the target object. transmission.

Specifically, the time when the state of the target object is adjusted from the first state to the second state may be implemented in the following manners:

B1. The state of the target object is detected when the PDCCH indicating that the terminal performs uplink transmission on the target object or the first preset time after the PDCCH indicating that the terminal performs uplink transmission on the target object is monitored. Adjusting from the first state to the second state;

In this implementation manner, the terminal may perform adjustment of the target state when monitoring the PDCCH indicating that the terminal performs uplink transmission on the target object; the terminal may also monitor the terminal to perform uplink transmission on the target object. The target object state is adjusted at a later time in the PDCCH time. For example, the terminal adjusts the target object state in the third second after listening to the PDCCH indicating that the terminal performs uplink transmission on the target object.

B2, adjusting a state of the target object from a first state to a second state when a random access preamble is sent or after a random access preamble is sent;

B3. Adjust the state of the target object from the first state to the second state when receiving the random access response or receiving the random access response at a third preset time.

It should be noted that the specific implementation manners of the latter two are similar to the first implementation manner, and only refer to the object when the state adjustment is performed. (The reference object of the first implementation manner is to monitor the PDCCH, and the reference object of the second implementation manner is The random access preamble is sent, and the reference object of the third implementation is a random access response. The two implementations are not described again.

It should be noted that the terminal may adjust the state at any time in any of the above three implementation manners.

2. When the triggering condition includes the configured beam failure of the target object of the target object,

In this case, the specific implementation of the step 502 is: sending a beam failure recovery request to the network device on the target object or the first object; further, the specific implementation manner of step 503 is: receiving the network The beam recovery response sent by the device.

It should be noted that the first object is another target object different from the target object.

Generally, the beam recovery response may include beam information that needs to be recovered. When receiving the beam recovery response, the terminal only needs to perform beam recovery according to the beam information in the beam recovery response.

It should be noted that, in this case, the terminal may also select an adjustment of the state of the target object to be configured. Specifically, the terminal adjusts the state of the target object from the first state to the second state. The second state is an active state, that is, the terminal should adjust the state of the configured target object from the new state to the active state to indicate that information can be transmitted on the target object.

C1. Adjusting the state of the target object from the first state to the second state when the configured beam presence beam failure of the target object or the configured beam failure of the target object beam fails. status;

In this implementation manner, the terminal may perform adjustment of the target state when the configured beam of the target object fails to be configured; the terminal may also perform the next time when the configured beam of the target object fails to exist. The adjustment of the target object state, for example, the terminal performs the adjustment of the target object state in the third second after the configured beam presence beam failure of the target object.

C2, adjusting a state of the target object from a first state to a second state at a fifth preset time after transmitting a beam failure recovery request or a beam failure recovery request;

C3. Adjust the state of the target object from the first state to the second state when receiving the beam recovery response or receiving the beam recovery response at a sixth preset time.

It should be noted that the specific implementation manners of the latter two are similar to the first implementation manner, except that the reference object is used for the state adjustment (the reference object of the first implementation manner is that the configured beam of the target object has a beam failure, the first The reference object of the two implementation manners is the transmission beam failure recovery request, and the reference object of the third implementation manner is that the received beam recovery response is different, and the latter two implementation manners are not described again.

In the foregoing embodiment of the present disclosure, when the state of the target object configured by the terminal is the first state, if there is a trigger condition for information transmission, the information corresponding to the trigger condition is transmitted to the network device, and the response of the network device is received. The information can be used to transmit information in the new state or deactivated state of the target object, realize information synchronization, avoid the problem of delaying the use of the target object, and ensure the timeliness of network communication.
