Description

Data transmission method, equipment and system

This application claims priority from a Chinese patent application filed on June 19, 2018 with the Chinese Patent Office, application number 201810629605.5, and application name "A Data Transmission Method, Device, and System", the entire contents of which are incorporated herein by reference. Applying.

Technical field

Embodiments of the present invention relate to the field of communications technologies, and in particular, to a data transmission method, device, and system.

Background technique

At present, the fifth generation wireless communication (5-Generation, 5G) system has a total of 64 logical channel identifiers (LCID). For downlink data transmission, the downlink logical channel occupies 32 LCIDs (called legacy LCID), the downlink media access control (MAC) control unit occupies 17 LCIDs, and the remaining 15 LCIDs are reserved LCIDs. For uplink data transmission, the uplink logical channel occupies 32 LCIDs, the uplink MAC control unit occupies 10 LCIDs, and the remaining 22 LCIDs are reserved LCIDs.

In order to improve the reliability of data transmission, the 5G new radio (NR) system introduces the packet data convergence protocol (PDCP) packet duplication function. That is, for radio bearers (including data radio bearers (DRB) and signal radio bearers (SRB)), network devices can configure PDCP packet replication for these radio bearers. Specifically, after the data transmitted by a radio bearer is copied by the PDCP entity at the PDCP layer, the original data and the copied data are transmitted to two different radio link control (RLC) entities. In a carrier aggregation (CA) scenario, the two RLC entities are in the same cell group and correspond to different logical channels, and different logical channels have different LCIDs.

However, according to the current protocol, in the worst case (supporting 8 CA DRB duplication and 2 CA SRB duplication), the legacy LCID can only support a maximum of 19 DRBs between User Equipment (UE) and network equipment. Therefore, as the business needs of the UE increase, if it is necessary to support the establishment of more DRBs between the UE and the network equipment, the number of the reserved LCIDs may not be able to meet the expansion requirements, resulting in failure to provide better quality of service.

In the description of the embodiments of the present invention, unless otherwise stated, the meaning of “a plurality” refers to two or more than two, for example, a plurality of processing units refers to two or more processing units and the like.

Embodiments of the present invention provide a data transmission method, device, and system that can obtain a first identifier (the first identifier is used to indicate a logical channel or schedule a first transmission channel, and the domain where the first identifier is located includes N bits); If the first identifier is used to indicate a logical channel, N is an integer greater than 6; or, if the first identifier is used to schedule a first transmission channel, N is an integer greater than 16), and indicated in the first identifier Sending the first data on the logical channel or the first transmission channel scheduled by the first identifier. With this solution, on the one hand, compared with the prior art where the logical channel identifier includes 6 bits, because the number of bits included in the domain where the first identifier provided by the embodiment of the present invention is greater than 6, the present invention implements The example extends the number of bits used to indicate the domain of the identifier of the logical channel, so that more radio bearers can be established between the UE and the access network device. On the other hand, compared with the domain where the temporary identification of the cell wireless network in the prior art includes 16 bits, since the domain where the first identifier provided by the embodiment of the present invention includes more than 16 bits, the present invention implements The example expands the number of bits in the domain where the identification of the transmission channel is located, so that the access network device can schedule more transmission channels for the UE, which can support the establishment of more radio bearers between the UE and the access network device. That is, in the embodiment of the present invention, since more radio bearers can be established between the UE and the access network device, it can meet the growing service requirements of the UE and provide better service quality.

The data transmission method, device, and system provided by the embodiments of the present invention can be applied to a communication system. For example, when the first identifier is an LCID, it may be specifically applied to a process of transmitting data between a UE and a network device based on the communication system.

Exemplarily, FIG. 1 shows a schematic architecture diagram of a communication system according to an embodiment of the present invention. As shown in FIG. 1, the communication system may include UE 01 and access network device 02. Among them, a connection can be established between the UE 01 and the access network device 02.

It should be noted that, in the embodiment of the present invention, the UE 01 and the access network device 02 shown in FIG. 1 described above may be wirelessly connected.

A UE is a device that provides users with voice and / or data connectivity, a handheld device with wired / wireless connectivity, or other processing equipment connected to a wireless modem. The UE may communicate with one or more core network devices through a radio access network (Radio Access Network, RAN). The UE can be a mobile terminal, such as a mobile phone (also called a "cellular" phone) and a computer with a mobile terminal. It can also be a portable, pocket, handheld, computer-built or vehicle-mounted mobile device that exchanges language with the RAN. And / or data, for example, Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistant (Personal Digital Assistant) , PDA) and other equipment. The UE may also be called a user agent (User Agent) or a terminal device.

An access network device is a device that is deployed in the RAN to provide wireless communication functions for the UE. In the embodiment of the present invention, the access network device may be a base station, and the base station may include various forms of macro base stations, micro base stations, relay stations, access points, and so on. In systems using different wireless access technologies, the names of base station-capable devices may vary. For example, in a 5G system, it can be called a 5G base station (gNB); in a 4th generation wireless communication (4-Generation, 4G) system, such as a long term evolution (LTE) system, it can be called an evolved base station (evolved NodeB, eNB); in the third generation mobile communication (3G) system, it may be referred to as a base station (NodeB). As communication technology evolves, the name "base station" may change.

The data transmission method, device, and system provided by the embodiments of the present invention will be described in detail through specific embodiments and application scenarios thereof with reference to the accompanying drawings.

Based on the communication system shown in FIG. 1, an embodiment of the present invention provides a data transmission method. As shown in FIG. 2, the data transmission method may include steps 201 to 203 described below.

Step 201: The UE obtains a first identifier.

The first identifier may be used to indicate a logical channel or schedule a first transmission channel. The domain where the first identifier is located includes N bits. If the first identifier is used to indicate a logical channel, N is an integer greater than 6; or if the first identifier is used to schedule a first transmission channel, N is an integer greater than 16.

Optionally, in the embodiment of the present invention, when the first identifier is used to indicate a logical channel, the first identifier may be a logical channel identifier (LCID). In the case where the first identifier is used to schedule the first transmission channel, the first identifier may be a cell radio network temporary identity (C-RNTI).

It should be noted that in the case where the first identifier is used to indicate a logical channel, the domain where the LCID is located in the prior art includes 6 bits. The LCID (that is, the first identifier) provided by the embodiment of the present invention is different. The field includes N bits (N is an integer greater than 6). In the case where the first identifier is used for scheduling the first transmission channel, the domain where the C-RNTI is located in the prior art includes 16 bits. The C-RNTI (that is, the first identifier) provided by the embodiment of the present invention is different. The field of N includes N bits (N is an integer greater than 16).

Optionally, in the embodiment of the present invention, the first identifier may be defined in a communication protocol, or may be configured for a UE by an access network device. Specifically, if the first identifier is defined in the communication protocol, the UE may obtain the first identifier by reading the communication protocol; if the first identifier is configured by the access network device for the UE, the UE may receive from the access network device First logo. Specifically, it may be determined according to actual use requirements, and the embodiment of the present invention is not limited.

It can be understood that when the access network device configures the first identity for the UE, the access network device can read the first identity from the communication protocol, and the access network device can also obtain the first identity through other possible methods. Specifically, it may be determined according to actual use requirements, and the embodiment of the present invention is not limited.

Optionally, in the embodiment of the present invention, in a case where the first identifier is used to indicate a logical channel, the N bits may include a first bit, and the first bit may be reserved in a MAC subheader. Bit or extended bit.

It should be noted that, in the embodiment of the present invention, the reserved bit or the extended bit may be an idle bit in the MAC subheader, that is, a bit that is not yet occupied. For example, the reserved bit may be an original idle bit in the MAC subheader; the extended bit may be a newly added idle bit in the MAC subheader.

It can be understood that in the case where the first identifier is used to indicate a logical channel, since the first bit of the N bits is a reserved bit or an extended bit in the MAC subheader, the embodiment of the present invention expands The number of bits contained in the domain where the LCID is located. This solves the problem that the number of LCIDs in the prior art may not be able to meet the transmission. This can support the establishment of more wireless bearers between the UE and the access network equipment, and can meet the increasing growth. UE business needs.

Further, in the embodiment of the present invention, when the first bit is a reserved bit in the MAC subheader, the N bits may be 6 + M bits, and the first bit may be the M bits out of 6 + M bits. Among them, M is a positive integer.

For example, M can be 1, 2, or 3 and so on. Specifically, it may be determined according to actual use requirements, and the embodiment of the present invention is not limited.

For example, FIG. 3 is a schematic diagram of several first identifiers according to an embodiment of the present invention. In the case where the first identifier is the LCID and the first bit is a reserved bit in the MAC subheader, assuming M is 1, the domain where the first identifier is located may include 7 bits, and the first bit Bits can be reserved for one of the seven bits. Specifically, as shown in FIG. 3 (a) or as shown in FIG. 3 (b), the 1 reserved bit may be a bit adjacent to the "F" domain in the domain where the LCID is located ( That is, the bit corresponding to "1" as shown in (a) in FIG. 3 or (b) in FIG. 3). As shown in FIG. 3 (c), the 1 reserved bit may be a bit adjacent to the “R” domain in the domain where the LCID is located (that is, as shown in (c) in FIG. 3). "1" corresponding bit). Among them, "L" is used to indicate the length of the service data unit (SDU) or control message; "R" is a reserved bit; "F" is used to indicate whether the length of the SDU or control message is greater than 128 bytes Specifically, if F = 1, "F" is used to indicate that the length of the SDU or control message is greater than 128 bytes; if F = 0, then "F" is used to indicate that the length of the SDU or control message is less than or equal to 128 words Section.

Understandably, in the case where the first identifier is used to indicate a logical channel, by setting a reserved bit in the MAC subheader to the first bit, both the normal use of the MAC subheader can be guaranteed and the first identifier can be extended. Number of bits in the domain. In this way, the problem that the number of LCIDs in the prior art may not be able to meet the transmission is solved, so that more radio bearers can be established between the UE and the access network device, and thus the growing service needs of the UE can be met.

Further, in the embodiment of the present invention, when the first bit is an extended bit in the MAC subheader, the N bits are 6 + 8 * K bits, and the first bit is the 6 Bits corresponding to K bytes of + 8 * K bits. Among them, K is a positive integer.

For example, K can be 1, 2, or 3, and so on. Specifically, it may be determined according to actual use requirements, and the embodiment of the present invention is not limited.

Exemplarily, FIG. 4 is a schematic diagram of several other first identifiers according to an embodiment of the present invention. In the case where the first identifier is the LCID and the first bit is an extended bit in the MAC subheader, assuming K is 1, the domain where the first identifier is located may include 14 bits, and the first bit may be It is the bit corresponding to one extended byte of the 14 bits. Specifically, as shown in (a) in FIG. 4, (b) in FIG. 4, or (c) in FIG. 4, the 14 bits may include the 6 bits corresponding to the LCID (1) and The 8 bits corresponding to the LCID (2), and the bits corresponding to the 1 extension byte may be the 8 bits corresponding to the LCID (2). Among them, "L" is used to indicate the length of the service data unit (SDU) or control message; "R" is a reserved bit; "F" is used to indicate whether the length of the SDU or control message is greater than 128 bytes Specifically, if F = 1, "F" is used to indicate that the length of the SDU or control message is greater than 128 bytes; if F = 0, then "F" is used to indicate that the length of the SDU or control message is less than or equal to 128 words Section.

It can be understood that when the first identifier is used to indicate a logical channel, by using the extended bit in the MAC subheader as the first bit, both the normal use of the MAC subheader and the domain where the first identifier is located can be extended. The number of bits. This solves the problem that the number of LCIDs in the prior art may not be able to meet the transmission problem, so that more radio bearers can be established between the UE and the access network equipment, which can meet the growing UE business needs and provide better services. quality.

Optionally, in the embodiment of the present invention, in a case where the first identifier is used to schedule a first transmission channel, the N bits may be 8 * T bits, and T is an integer greater than 2.

Exemplarily, FIG. 5 is a schematic diagram of several other first identifiers according to an embodiment of the present invention. In the case where the first identifier is C-RNTI, assuming T is 3, the domain where the first identifier is located may include 24 bits. Specifically, as shown in FIG. 5 (a), the 24 bits may include bits corresponding to C-RNTI (1), C-RNTI (2), and C-RNTI (3), respectively, and the C-RNTI (3) The corresponding 8 bits can be the bits corresponding to the extended byte. It can be understood that when the first identifier is a C-RNTI, T may also be another possible integer value (for example, 4, 5, or 6). As shown in FIG. 5 (b), the domain where the first identifier is located may include 8 * T bits, and the 8 * T bits may include C-RNTI (1), C-RNTI (2), ... ..., and corresponding bits such as C-RNTI (T).

It can be understood that in the case where the first identifier is used to schedule the first transmission channel, by expanding the number of bits of the domain where the first identifier is located, the access network device can schedule more transmission channels for the UE, thereby supporting the UE and the receiver. Establish more wireless bearers between networked devices, which can meet the growing needs of UE services and provide better service quality.

Step 202: The UE sends the first data on the logical channel indicated by the first identifier or the first transmission channel scheduled by the first identifier.

Optionally, in the embodiment of the present invention, the foregoing first data may be data or a data packet carried on the first radio bearer, that is, the first radio bearer may be a data radio bearer.

In the embodiment of the present invention, when the first identifier is used to indicate a logical channel, the UE may send the first data carried on the first radio bearer on the logical channel indicated by the first identifier. In the case where the first identifier is used to schedule the first transmission channel, the UE may send the first data carried on the first radio bearer on the first transmission channel according to the first identifier.

Optionally, before the UE sends data on the logical channel indicated by the first identifier or the first transmission channel scheduled by the first identifier, the data transmission method provided by the embodiment of the present invention may further include: between the UE and the access network device Establish a first radio bearer. The first radio bearer corresponds to a logical channel or a first transmission channel.

Step 203: The access network device receives the first data sent by the UE on the logical channel indicated by the first identifier or the first transmission channel scheduled by the first identifier.

According to the data transmission method provided by the embodiment of the present invention, on the one hand, compared with the prior art where the logical channel identifier includes 6 bits, the number of bits included in the domain where the first identifier provided by the embodiment of the present invention is greater than 6. Therefore, the embodiment of the present invention expands the number of bits used to indicate the domain where the identifier of the logical channel is located, so that more radio bearers can be established between the UE and the access network device. On the other hand, compared with the domain where the temporary identification of the cell wireless network in the prior art includes 16 bits, since the domain where the first identifier provided by the embodiment of the present invention includes more than 16 bits, the present invention implements The example expands the number of bits in the domain where the identification of the transmission channel is located, so that the access network device can schedule more transmission channels for the UE, which can support the establishment of more radio bearers between the UE and the access network device. That is, in the embodiment of the present invention, since more radio bearers can be established between the UE and the access network device, it can meet the growing service requirements of the UE and provide better service quality.

Optionally, in combination with FIG. 2 and FIG. 6, in the embodiment of the present invention, the foregoing step 201 may be specifically implemented by the following step 201A. In addition, before the above step 201A, the data transmission method provided by the embodiment of the present invention may further include the following step 204.

Step 204: The access network device sends a first identifier to the UE.

Step 201A: The UE receives the first identifier.

The first identifier may be used to instruct the UE to send the first data on the logical channel indicated by the first identifier or the first transmission channel scheduled by the first identifier.

For the specific description of the first identifier, refer to the related description of the first identifier in step 201 of the foregoing embodiment, and details are not described herein again.

Exemplarily, when the first identifier is used to indicate a logical channel, a method for the access network device (for example, a base station) to send the first identifier to the UE may include: the access network device may send a radio resource control (radio resource) to the UE. control (RRC) signaling, where the RRC signaling may include DRB information, and the DRB information may include the first identifier. In this way, the UE can receive the first identifier and send the first data carried on the first radio bearer on the logical channel indicated by the first identifier.

Exemplarily, when the first identifier is used to schedule a first transmission channel, the access network device (for example, a base station) may send the first identifier to the UE, where the first identifier may be used to schedule a newly defined transmission channel. (That is, the first identifier can be used to schedule a newly added transmission channel). Specifically, it is different from the existing downlink shared channel (DL-SCH) and the existing uplink shared channel (UL-SCH). The newly defined downlink sharing provided by the embodiment of the present invention is different. The channel may be a downlink shared extended channel (downlink shared channel-bis, DL-SCH-bis), and the newly defined uplink shared channel may be an uplink shared extended channel (uplink shared channel-bis, UL-SCH-bis). In this way, the UE can receive the first identity and transmit the first data carried on the first radio bearer on UL-SCH-bis or DL-SCH-bis.

In the data transmission method provided in the embodiment of the present invention, the UE may receive the first identifier sent by the access network device, and send the first data carried on the first radio bearer on the logical channel indicated by the first identifier, or the UE may According to the first identification, the first data carried on the first radio bearer is sent on the first transmission channel.

Optionally, in combination with FIG. 6, as shown in FIG. 7, in the embodiment of the present invention, when the first identifier is used to schedule the first transmission channel, the above step 204 may be specifically implemented by the following step 204A. Moreover, at this time, the above step 202 can be specifically implemented by the following step 202A.

Step 204A: When the number of target radio bearers is greater than or equal to the first threshold, the access network device sends a first identifier to the UE.

The target radio bearer may include a radio bearer established between the UE and the access network device and a radio bearer to be established between the UE and the access network device.

Exemplarily, in the embodiment of the present invention, the number of the foregoing target radio bearers may be eight or sixteen. Specifically, it may be determined according to actual use requirements, and the embodiment of the present invention is not limited.

Step 202A: The UE sends the first data on the first transmission channel scheduled by the first identifier.

In the data transmission method provided by the embodiment of the present invention, an access network device may send a first identifier to a UE when the number of target radio bearers is greater than or equal to a first threshold, so that the UE may use the first identifier to The transmission channel sends first data carried on the first radio bearer. That is, the access network device can schedule more transmission channels for the UE, which can support the establishment of more radio bearers between the U and the access network device, which can meet the growing needs of UE business and provide better service quality. .

Optionally, in combination with FIG. 7, as shown in FIG. 8, in the embodiment of the present invention, in a case where the first identifier is used to schedule a first transmission channel, the data transmission method provided by the embodiment of the present invention may further include the following: Steps 205-208.

Step 205: The access network device sends a second identity to the UE.

The second identifier may be used to schedule a second transmission channel, the second identifier belongs to the same domain as the first identifier, and the second identifier may be used by the UE to send data on the second transmission channel.

Step 206: The UE receives the second identity.

Step 207: The UE sends the second data on the second transmission channel scheduled by the second identifier.

Step 208: The access network device receives the second data sent by the UE on a second transmission channel scheduled by the second identifier.

It should be noted that, in the embodiment of the present invention, the first identifier and the second identifier may be different identifiers.
