Description

Method and device for data transmission initiated by terminal

The invention belongs to the field of wireless communication technology, and particularly relates to a terminal-initiated data transmission method and device.

Identification), and use the C-RNTI identifier to transmit data with the terminal. When the terminal actively accesses the network or initiates data transmission with the network side, it usually initiates a random access process first.

The disadvantage of the related technology is that in the LTE system, when the terminal initiates transmission during initial access and other conditions without uplink transmission resource configuration, a random access process is first required. During transmission access, a unique identifier C-RNTI in the cell needs to be allocated through a random access process to carry out the subsequent data transmission process.

The drawings described here are used to provide a further understanding of the present invention and constitute a part of the present invention. The exemplary embodiments of the present invention and the description thereof are used to explain the present invention, and do not constitute an improper limitation of the present invention.

Random access in the LTE system is divided into two types: competitive random access and non-competitive random access.

Competitive random access is used for the following purposes: initial terminal access; RRC (Radio Resource Control, Radio Resource Control) connection reestablishment; handover; downlink data arrival in the RRC connection state in an asynchronous state; uplink data arrival in the RRC connection state; RRC Positioning in the connected state.

Figure 1 is a schematic diagram of the competitive random access process. The process is shown in Figure 1, and is mainly divided into four steps: Msg1: UE (User Equipment) selects random access preamble (random access preamble) and PRACH ( Physical Random Access Channel, physical random access Channel) resource and use the PRACH resource to send the selected random access preamble to the base station; Msg2: The base station receives the preamble, calculates TA (Time Alignment, timing advance), and sends a random access response to the UE. The incoming response includes the timing advance information, the UL grant (uplink grant) for Msg3, and the temporary C-RNTI allocated by the network side. The PDCCH (Physical Downlink Control Channel) that carries the Msg2 scheduling message is scrambled with RA-RNTI (Random Access-Radio Network Temporary Identity). RA-RNTI is in a 10ms window. The time-frequency resource for sending Msg1 uniquely corresponds; in addition, Msg2 also carries the preamble ID, and the UE determines that the Msg2 corresponds to the Msg1 sent by the UE through RA-RNTI and preamble ID; Msg3: the UE sends uplink transmission on the UL grant specified by Msg2, The content of Msg3 uplink transmission is different for different random access reasons. For example, for initial access, Msg3 transmits an RRC connection establishment request; Msg4: contention resolution message. The UE can determine whether the random access is successful according to Msg4. For the initial access UE, the temporary C-RNTI is automatically converted into the C-RNTI, which is the unique UE identification of the UE in the cell, after the contention is resolved successfully.

Non-contention random access is used for handover; downlink data arrival; positioning and obtaining uplink timing.

Figure 2 is a schematic diagram of the non-competitive random access process. As shown in Figure 2, it is mainly divided into three steps: Msg0: the base station allocates a dedicated preamble for non-competitive random access to the UE and PRACH resources for random access; Msg1 : UE sends to the base station on the designated PRACH resource according to the instruction of Msg0 The designated dedicated preamble. After receiving Msg1, the base station calculates the uplink timing advance TA according to Msg1; Msg2: the base station sends a random access response to the UE. The random access response includes timing advance information and subsequent uplink transmission resource configuration UL grant, which is used for timing advance The timing relationship for the UE's subsequent uplink transmission.

In the LTE system, when the terminal initiates transmission during initial access and other situations where there is no uplink transmission resource configuration, it first needs to perform a random access process. During transmission access, a unique identification C-RNTI in the cell must be allocated through the random access process to carry out the subsequent data transmission process, and the delay of the random access process of the LTE system is particularly unfavorable to the low-latency requirements of the new generation 5G system. Based on this, the embodiment of the present invention provides a terminal-initiated data transmission scheme. The terminal sends a serial code associated with the terminal ID to the network side. After receiving the serial code, the network side uses the terminal ID associated with the terminal. Serial code and/or terminal identification for data transmission. The specific embodiments of the present invention will be described below with reference to the accompanying drawings.

In the description process, the terminal and network side implementation will be described separately, and then an example of the implementation of the two will also be given to better understand the implementation of the solution given in the embodiment of the present invention. This way of explanation does not mean that the two must be implemented together or implemented separately. In fact, when the terminal and the network side are implemented separately, they also solve the problems of the terminal side and the network side respectively, and when the two are used in combination, Will get better technical results.

Figure 3 is a schematic diagram of the implementation process of the data transmission method initiated by the terminal on the terminal side. As shown in the figure, it includes: step 301, sending a serial code associated with the terminal identity on the terminal to the network side, the terminal identity and/or serial code Is the unique identifier of the terminal; Step 302: After receiving the serial code on the network side, it uses the serial code and/or terminal identity associated with the terminal identity to perform data transmission with the network side.

Figure 4 is a schematic diagram of the implementation process of a data transmission method initiated by a terminal on the network side. As shown in the figure, it includes: step 401, receiving a serial code associated with a terminal identity sent by the terminal to the network side, the terminal identity and/or serial code It is the unique identifier of the terminal; step 402, after receiving the serial code on the network side, the terminal uses the serial code and/or terminal identifier associated with the terminal identifier to perform data transmission.

In the implementation of steps 302 and 402, after receiving the serial code, the network side uses the serial code associated with the terminal identification and/or the terminal identification to perform data transmission with the terminal. The data transmission here includes uplink and downlink transmission.

In the case of uplink transmission, after the sequence code is sent on the terminal side, the uplink resource configuration on the network side is received, and the uplink transmission is sent on the allocated resources. This solution will be illustrated through Examples 2, 3, 4, etc.

In the case of downlink transmission, if the base station directly recognizes the terminal, it can initiate the downlink transmission immediately. This solution will be described in Embodiment 1 and so on; it may also be that the base station directly schedules and sends downlink transmissions, such as Embodiment 6, TA The sending is just a downlink transmission sending.

The terminal identification and serial code in the implementation will be described below first.

Terminal identification: refers to the identification of the terminal in a certain network area, which is different from the C-RNTI that the LTE system can identify within a cell range. The terminal identification can be the entire network or under a specific operator or contains multiple TPs Point, the transmission point) can be identified within the area Of the logo. The terminal identifier is divided into a high-level terminal identifier and a physical-layer terminal identifier (for example, C-RNTI is the physical-layer terminal identifier of the LTE system). The high-level terminal identifier (higher layer UE ID) has a relatively large length and is unique within the above-mentioned specified range; The layer identifier (physical UE ID) is limited by its length, and may be unique within the above-mentioned specified range or need to be combined with other information to uniquely identify the terminal.

The aforementioned physical UE ID may also be a similar name such as an air terminal identifier, as long as its purpose is to identify a terminal in a similar manner provided in the embodiment of the present invention during air transmission. It is not limited to the above-mentioned terminal identifiers.

The sequence code associated with the terminal identification: use this sequence code to initiate transmission to the network side, which is different from the preamble code shared and randomly selected by the UE in the LTE system and the dedicated preamble code that needs to be allocated by the network side dedicated signaling. This sequence code is designed to be The terminal identification is directly related. There are several possible usages: 1. The terminal ID is the unique ID of the terminal, and the serial code is the unique ID of the terminal; the physical layer terminal ID and the serial code sync1 are both unique to the terminal, and the network side can pass through any one unique Identify the terminal; 2. The combination of the terminal ID and a serial code is the unique ID of the terminal; the combination of the physical layer terminal ID + serial code sync1 forms a unique terminal ID, and the network side uniquely identifies the terminal by detecting sync1 and the physical layer terminal ID; 3 , The combination of the terminal identifier and multiple serial codes is the unique identifier of the terminal, and there is an association relationship between the multiple serial codes.

Multiple sequence codes are associated with the terminal identification, and the sequence codes are related to each other. For example, sync1 is used for initial sequence code transmission, and sync3 is used for transmission with subsequent uplink transmission.

In the implementation, the association relationship between the terminal identification and the serial code can be the terminal and the network Predicted by the roadside; or, the association relationship between the terminal ID and the serial code is learned through the interaction between the terminal and the network side.

The implementation of these two methods will be described below in conjunction with examples. In the description process, the temporarily used physical UE ID is abbreviated as temporary physical UE ID for the convenience of expression. In order to more appropriately describe the correspondence between the physical UE ID and the sequence code, it will also be expressed as the corresponding physical UE ID. .

1. The association between the terminal ID and the serial code is foreseen by the terminal and the network side.

1) The terminal ID is the unique ID of the terminal, and when the serial code is the unique ID of the terminal, the serial code is used for the network side to identify the terminal ID of the terminal according to the association relationship, and the terminal ID is used for the network side for data transmission ; Specifically, the physical UE ID and sync1 are unique to the terminal, and the network side can uniquely identify the terminal through any one.

When the terminal needs to initiate transmission, it sends the sync1 sequence on the uplink channel; the network-side transmission point receives and recognizes sync1 and determines the corresponding physical UE ID, and then uses the physical UE ID to transmit data with the terminal.

Example 1: In this embodiment, both the physical UE ID and sync1 are unique to the terminal. Figure 5 is a schematic diagram of the implementation process of Embodiment 1. As shown in the figure, it can include the following steps: Step 501: The terminal sends sync1 on the uplink channel, and the sync1 uniquely identifies a terminal and corresponds to a physical UE ID; Step 502: Network The roadside transmission point identifies the terminal and determines its corresponding physical UE ID, The network-side transmission point receives and recognizes sync1 and determines the corresponding physical UE ID; step 503: the network-side transmission point and the terminal use the physical UE ID and sync1 (may include sync3) for over-the-air transmission, and the subsequent network side and the terminal use this The physical UE ID performs data scheduling and transmission.

2) When the terminal ID and a serial code are combined to be the unique ID of the terminal, the serial code is used for the network side to allocate a temporary terminal ID for the terminal, and the temporarily used terminal ID is used for the network side to allocate and transmit the terminal Identified resources; specifically, when the combination of physical UE ID and sync1 uniquely determines the terminal, when the terminal needs to initiate transmission, it sends the sync1 sequence on the uplink channel; the network-side transmission point receives and recognizes sync1 and uses the temporary physical UE ID to allocate uplink resources; The terminal performs uplink transmission on the uplink resources allocated by the network side and carries the physical UE ID; the network side transmission point receives the uplink transmission and uniquely identifies the terminal, and the terminal can be given necessary feedback during specific implementation.

Example 2

In this embodiment, the terminal is determined by the combination of the physical UE ID and sync1. Figure 6 is a schematic diagram of the implementation process of Embodiment 2. As shown in the figure, the following steps may be included:

Step 601: The terminal sends sync1 on the uplink channel.

For the terminal, the combination of the sync1 and a physical UE ID uniquely determines the terminal, but the sync1 itself may correspond to multiple physical UE IDs;

Step 602: The network-side transmission point uses the temporary physical UE ID to allocate uplink resources. The network-side transmission point receives and recognizes sync1 and uses the temporary physical UE ID to allocate uplink resources. The temporary physical UE ID can be combined with sync1 and/or its transmission time-frequency resource location Association, such as randomly selecting one of the possible physical UE IDs corresponding to sync1 as the temporary physical UE ID;

Step 603: The terminal performs uplink transmission on the uplink resources allocated by the network side, and carries the physical UE ID of the terminal. In specific implementation, it may also send sync3 corresponding to the physical UE ID;

Step 604: The network-side transmission point receives the uplink transmission and uniquely identifies the terminal through sync1 and the physical UE ID sent by the terminal. In specific implementation, the network-side transmission point can also provide necessary feedback to the terminal, for example, feedback confirmation or failure;

Step 605: The network-side transmission point and the terminal use the physical UE ID and sync1 (may include sync3) for air transmission.

3) The combination of the terminal ID and multiple serial codes is the unique ID of the terminal. When there is an association relationship between the multiple serial codes, the first serial code is used for the network side to assign the terminal ID for temporary use to the terminal. The temporarily used terminal ID is used for the network side to allocate resources for transmitting the terminal ID and the second serial code. The second serial code and terminal ID are used for the network side to uniquely identify the terminal ID of the terminal; specifically, in the physical When the UE ID and sync3 combination uniquely determines the terminal, the terminal sends the sync1 sequence on the uplink channel when it needs to initiate transmission; the network-side transmission point receives and recognizes sync1 and uses the temporary physical UE ID to allocate uplink resources, where sync1 and sync3 have a corresponding relationship; The terminal performs uplink transmission on the uplink resources allocated on the network side, carries the physical UE ID, and sends the uplink sequence sync3 at the same time; the network side transmission point receives the uplink transmission and uniquely identifies the terminal according to the combination of physical UE ID and sync3, which can perform necessary operations on the terminal Feedback.

Example 3

In this embodiment, the combination of the physical UE ID and sync3 uniquely determines the terminal. Figure 7 is a schematic diagram of the implementation process of Embodiment 3. As shown in the figure, the following steps may be included: Step 701: The terminal sends sync1 on the uplink channel; Step 702: The network side transmission point uses the temporary physical UE ID to allocate uplink resources, and the network side transmission point receives and recognizes sync1 and uses the temporary physical UE ID to allocate uplink resources. The temporary physical UE ID can Associate with sync1 and/or its sending time-frequency resource location, for example, sync1 uniquely corresponds to a temporary physical UE ID; step 703: the terminal performs uplink transmission on the uplink resource allocated by the network side and carries the physical UE ID of the terminal, and at the same time The uplink sequence sync3 is sent on the uplink TTI (Transmission Time Interval); step 704: the network-side transmission point receives the uplink transmission, using the physical UE ID carried in the uplink transmission and sync3 simultaneously sent on the uplink TTI, The terminal is uniquely determined. In the specific implementation, the network-side transmission point can also provide necessary feedback to the terminal. For example, feedback confirmation or failure, in steps 703 and 704, TTI is expressed as an uplink transmission unit, which can be understood as similar to "an uplink sub-frame" described in LTE. The purpose of this expression is mainly to emphasize that the uplink transmission and sync3 are sent in the same uplink transmission unit; step 705: the network side transmission point and the terminal use the physical UE ID and sync1 (may include sync3) for air transmission.

4) The combination of the terminal ID and multiple serial codes is the unique ID of the terminal. When there is an association relationship between multiple serial codes, the first serial code is used for the network side to determine the agreed transmission of the second serial code. Resources, the second serial code and the first serial code are used for the network side to uniquely identify the terminal identifier of the terminal.

When the terminal is uniquely determined through the combination of sync1 and sync3 and corresponds to a physical UE ID, the terminal sends the sync1 sequence on the uplink channel when it needs to initiate transmission; The roadside transmission point receives and recognizes sync1, (the network side can allocate or not allocate uplink transmission resources as needed); the terminal sends sync3 (according to Need to possibly send uplink data transmission); the network side transmission point receives sync3, and uniquely identifies the terminal according to the combination of sync1 and sync3.

In this embodiment, the combination of sync1 and sync3 uniquely determines the terminal, and corresponds to a physical UE ID. Figure 8 is a schematic diagram of the implementation process of Embodiment 4. As shown in the figure, it can include the following steps: Step 801: The terminal sends sync1 on the uplink channel; Step 802: The network side transmission point uses the temporary physical UE ID to allocate uplink resources; Network side transmission After the point receives and recognizes sync1, there are two ways: Method 1: The network side transmission point uses a temporary physical UE ID to allocate uplink resources to the terminal. The temporary physical UE ID can be associated with sync1 and/or its sending time-frequency resource location For example, randomly select one of the possible physical UE IDs corresponding to sync1 as the temporary physical UE ID, this method is the method shown in the figure; Method 2: The network side does not allocate uplink resources to the terminal; Step 803a: Corresponding method 1: The terminal is in Perform uplink transmission on the uplink resources allocated by the network side and carry the physical UE ID of the terminal, and at the same time send the uplink sequence sync3 on the uplink TTI; Step 803b: For mode 2: The terminal is in the uplink TTI (such as The uplink TTI separated by two TTIs) sends sync3. In the specific implementation, the network-side transmission point can also provide necessary feedback to the terminal. For example, feedback confirmation or failure. In this step, TTI is expressed as an uplink transmission unit, which can be understood as It is similar to "an uplink sub-frame" described in LTE. The purpose of this statement is mainly to emphasize that the uplink transmission and sync3 are sent in the same or different uplink transmission units with a timing relationship; step 804: the network side transmission point receives sync3, and uniquely identifies the terminal according to the combination of sync1 and sync3. The physical UE ID of the terminal can be further determined by means 1 of steps 802 and 803, and the temporary physical UE ID in step 802 is released.

2. The association relationship between the terminal ID and the serial code is learned through the interaction between the terminal and the network side.

On the terminal side, when the association relationship between the terminal ID and the serial code is known through the interaction between the terminal and the network side, the terminal selects a serial code in the first serial code optional resource pool to send it as the first serial code. The first serial code corresponds to a temporarily used terminal ID, and the temporarily used terminal ID is used for the network side to allocate resources for transmitting the terminal ID and the second serial code. The first serial code is the same as the second serial code. There is an association relationship between the serial codes, and the second serial code and the temporarily used terminal identifier are used for the network side to assign a terminal identifier to the terminal after confirming that the terminal is connected to the network.

Correspondingly, on the network side, when the association relationship between the terminal ID and the serial code is known through the interaction between the terminal and the network side: after receiving the first serial code sent by the terminal, it is based on the first serial code and the temporary use The corresponding relationship of the terminal identifier determines a temporarily used terminal identifier; according to the temporarily used terminal identifier, the terminal is allocated resources for the terminal to transmit the terminal identifier and the second serial code, the first serial code and the second serial code There is an association relationship between them; after receiving the terminal identification and the second serial code transmitted by the terminal on the resource, according to the second serial code and the temporarily used terminal identification, it is the terminal after confirming that the terminal is connected to the network Terminal points Equipped with terminal identification.

In this embodiment, the network side and the terminal have not yet established a consensus on the correspondence between the physical UE ID, sequence code, and the terminal. In this case, the physical UE ID and sequence code used by the terminal need to be determined through the interaction between the network side and the terminal.

Specifically, when the terminal has not obtained the unique high-level UE ID, for example, the unique high-level UE ID has not been obtained before the authentication of the terminal is successful on the network side.

After the network side authenticates the terminal successfully, the network side assigns a unique high-level UE ID to the terminal. The high-level UE ID has a direct correspondence with a specific physical UE ID and sequence code, and the corresponding physical UE ID and sequence code are used for processing. Subsequent data transmission is sufficient. For details, please refer to 1 that the association between the terminal identifier and the serial code is the implementation method foreseen by the terminal and the network side. That is, it can be referred to in subsequent use, and the difference is only that the way of obtaining the association relationship is different, 1 is foreseen, and 2 is learned through interaction.

The specific process can be as follows: the terminal selects a sequence code in the sync1 sequence optional resource pool to send as sync1, the sync1 code corresponds to a temporary physical UE ID; after the network side transmission point receives sync1, if the sync1 and its corresponding physical The UE ID is not occupied by other terminals, and the physical UE ID corresponding to the sync1 is used for data scheduling and transmission to the terminal. If it is occupied, a conflict indication is returned. The conflict indication may carry backoff parameters for initiating access after a delay. After the network side assigns a unique high-level UE ID to the terminal or after the terminal fails to access the network, the sync1 code and corresponding physical UE ID used in this access are released back to the resource pool for other terminals to compete for use.

Optionally, the sync1 has a one-to-one correspondence with another sequence code sync3. When sending uplink transmission, the terminal can carry the physical UE ID and send sync3 for the network side to identify the terminal end.

Example 5

Figure 9 is a schematic diagram of the implementation process of acquiring association relationships through interaction during initial access of the terminal. As shown in the figure, the following steps may be included: Step 901: The terminal sends sync1 on the uplink channel, and the terminal selects one from the sync1 sequence optional resource pool The sequence code is sent to the network side as sync1; step 902: the network side transmission point uses the temporary physical UE ID to allocate uplink resources, and the network side transmission point TP receives sync1 and uses the temporary physical UE ID corresponding to the sync1 to allocate uplink resources to the terminal, and the physical UE The ID can be implicitly or explicitly carried in the resource configuration command. Explicit means that the physical UE ID is directly a field of the uplink resource configuration command, and implicit means that the physical UE ID is added to the resource configuration command as a scrambling code, etc. , The terminal restores the resource configuration command by means of matched filtering; step 903: the terminal performs uplink transmission on the uplink resources allocated on the network side, and carries the temporary physical UE ID of the terminal, and the physical UE ID can also be sent in the specific implementation. Corresponding to sync3, the terminal initiates uplink transmission on the uplink resources allocated on the network side. The uplink transmission carries the temporary physical UE ID corresponding to sync1. The content of the uplink transmission includes the request and identity information required by the terminal to access the network. The terminal is optional Sync3 is sent within the same TTI of the uplink transmission. The sync3 has a corresponding relationship with sync1 and physical UE ID. In step 903, TTI is expressed as an uplink transmission unit, which can be understood as similar to the "one" described in LTE. Uplink sub-frame". The purpose of this expression is mainly to strengthen The uplink transmission and sync3 are tuned to be sent in the same uplink transmission unit; Step 904: The network side authenticates and allocates a unique high-level UE ID for the terminal; the network side transmission point identifies the terminal that initiated the transmission through the temporary physical UE ID and/or sync3. Get the uplink transmission content sent by the terminal, perform authentication and other operations, confirm that the terminal is connected to the network, and assign a high-level UE ID, which corresponds to the determined physical UE ID, sync1, sync3 (optional); steps 905: The network side and the terminal use the physical UE ID, sync1 and sync3 (optional) obtained in step 904 for data transmission.

In implementation, the temporary physical UE ID and the corresponding sync1 and sync3 can be released back to the resource pool. That is, after the terminal identifier is allocated to the terminal, it may further include: releasing the first sequence code, the temporarily used terminal identifier, and the second sequence code back to the resource pool; or, the first sequence The code and the temporarily used terminal identifier are released back to the resource pool.

In implementation, on the network side, it may further include: commanding the terminal to trigger the terminal to send the sequence code, and the sequence code is used for the network side to perform uplink timing estimation.

Correspondingly, on the terminal side, it may further include: upon receiving a command from the network side to send the sequence code, sending the sequence code, and the sequence code is used for the network side to perform uplink timing estimation.

Specifically, the command may be entity layer signaling or layer 2 control signaling.

Example 6: In the scenario of triggering the terminal to send the uplink sequence code to obtain the uplink timing on the network side, it is mainly The network side needs to use the uplink signal or data sent by the terminal to estimate the uplink timing. It can be implemented as follows: Step 1: The network side transmission point sends a command to the terminal to trigger the terminal to send sync1. The command can be physical layer signaling or layer 2 control signaling, which carries physical UE ID and/or downlink UE specific Sequence code (DL sync); Step 2: The terminal sends sync1; Step 3: The network side receives sync1 and uses sync1 to estimate the uplink timing, and sends the uplink timing command TA to the terminal.

In the implementation, the transmission belonging to multiple sequence codes, etc., can be implemented in the following manner in specific implementation.

As shown in the figure, suppose the terminal sends uplink sync1 transmission at the first sync1 position, and the network side transmission point sends the necessary uplink resource configuration to the terminal at the position corresponding to the first arrow. , The terminal sends uplink transmission and/or sync3 in the third uplink TTI.
