Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to an information transmission method and device. Background Art

[0002] In the current transmission mechanism, the terminal (UE) needs to be in a connected state to report content about service characteristics, such as through UE assistance messages or non-access stratum (NAS) signaling, such as service request messages to notify the network side.

[0003] When reporting in the connection state, the following factors are mainly considered:

[0004] For example, the uplink grant size, such as the size of message 3 (MSG3), is not sufficient to carry these signalings.

[0100] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0101] The embodiments of the present application provide an information transmission method and apparatus for reducing service delays.

[0102] Among them, the method and the device are based on the same application concept. Since the principles of solving problems by the method and the device are similar, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0103] The technical solutions provided in the embodiments of the present application can be applicable to a variety of systems, especially 5G systems. For example, applicable systems may be global system of mobile communication (GSM) systems, code division multiple access (CDMA) systems, wideband code division multiple access (WCDMA) general packet radio service (GPRS) systems, long term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, universal mobile telecommunication systems (UMTS), worldwide interoperability for microwave access (WiMAX) systems, 5G systems, and 5G NR systems. These various systems include terminal devices and network devices.

[0104] The terminal device involved in the embodiments of the present application may be a device that provides voice and / or data connectivity to a user, a handheld device with wireless connection function, or other processing device connected to a wireless modem. In different systems, the name of the terminal device may also be different. For example, in a 5G system, the terminal device may be called user equipment (UE). The wireless terminal device can communicate with one or more core networks via the RAN. The wireless terminal device can be a mobile terminal device, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal device. For example, it can be a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device that exchanges language and / or data with the wireless access network. For example, personal communication service (PCS) phones, cordless phones, session initiated protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), and other devices.

[0106] The following describes in detail the various embodiments of the present application in conjunction with the accompanying drawings. It should be noted that the order in which the embodiments of the present application are presented only represents the order of the embodiments, and does not represent the advantages or disadvantages of the technical solutions provided by the embodiments.

[0107] UE auxiliary information reporting process see Figure 1 In the New Access Network (NR), the UE sends its desired preferences to the network side through the UE Assistance Information message, such as whether to reduce bandwidth, whether to save energy, etc.

[0108] Of course, service characteristics, such as service cycle, data volume, etc., can also be sent through the UE Assistance Information message.

[0109] UE Assistance Information is carried on Signaling Radio Bearer (SRB) 1 or SRB3 bearer and is a signaling message sent to the network side after the UE enters the RRC connected state.

[0110] Regarding service request reporting, after triggering a service, the UE can send a ServiceRequest message to the network to report the type of service being requested. This includes information such as whether it is an emergency service, signaling, or a higher-priority access. However, this reporting requires the UE to be in the RRC connected state.

[0111] Contention random access process see Figure 2 NR defines two random access procedures: non-contention random access and contention random access. This article mainly introduces the contention random access procedure.

[0112] The contention random access process is mainly divided into four steps:

[0113] Step 1: The UE selects a preamble and sends it.

[0114] Step 2: The UE receives message 2 (Msg2) sent by the base station, namely, a random access response (RAR), and Msg2 includes uplink (UL) authorization information.

[0115] Step 3: The UE sends message 3 (Msg3) based on the UL grant included in Msg2. It should be noted that Msg3 is transmitted via the Hybrid Automatic Repeat Request (HARQ) process, and the HARQ process ID is fixed to 0.

[0116] During UL transmission, if the UE receives the UL grant contained in the RAR and if there is data in the Msg3 buffer, the UE will obtain the Media Access Control (MAC) Protocol Data Unit (PDU) from the Msg3.

[0117] At the same time, the data packet is placed in the HARQ buffer and the physical layer is instructed to execute the sending process according to the UL authorization information. The Msg3 sending process is as follows Figure 3 shown.

[0118] Step 4: UE receives Msg4.

[0119] The two-step random access (2-step RA) process is as follows Figure 4 Shown, including:

[0120] Step 1: The UE sends a preamble and uplink physical shared channel (PUSCH) in message A (MSGA), where the PUSCH resource may be notified by a broadcast message, and opens a message B (MSGB) window.

[0121] Step 2: The UE receives the MSGB during the MSGB window. During initial RRC setup, the MSGB can be either a success Random Access Response (RAR) or a fallback RAR. If the network successfully receives the MSGA, meaning it successfully receives the preamble and PUSCH in step 1, the network returns a success RAR.

[0122] If the network side only receives the Preamble, it will feedback the fallback RAR.

[0123] Integration of 5G systems and the Industrial Internet:

[0124] The Industrial Internet utilizes the Time Synchronization Network (TSN). As a typical deterministic network, the Industrial Internet precisely controls the arrival and transmission of business data, enabling accurate resource allocation and transmission. 5G systems are integrated into IEEE TSN as bridges.

[0125] The 5GS (5G system) uses 5G clock synchronization internally, and the TSN network uses TSN network clock synchronization. The nodes for 5GS and TSN clock conversion are the device-side TSN translator (DS-TT) on the terminal side and the network-side TSN translator (NW-TT) on the network side. During the time conversion process, delay jitter may be introduced from the external network to the 5GS, including:

[0126] Terminal side: Delay jitter between the TSN bridge and the DS-TT, and delay jitter between the DS-TT and the UE. DS-TT may be co-located with the UE and have no delay jitter. This delay jitter is called uplink delay jitter.

[0127] On the network side, the latency jitter of the N6 interface between the DN (Data Network) and the UPF is considered. Assuming the NW-TT and UPF are co-located, there is no latency jitter. The latency jitter introduced by the N6 interface (the interface between the Data Network (DN) and the User Plane Function (UPF) entity) is called the downlink burst spread (DL Burst Spread). The core network collects statistics on the DL Burst Spread and sends it, along with parameters such as the downlink data arrival time and period, to the base station via TSC Assistance Information (TSCAI). The base station then schedules downlink data transmission based on this information, ensuring deterministic downlink data transmission.

[0128] However, there is currently no solution for uplink delay jitter on the terminal side.

[0129] In IIoT services, latency requirements are relatively high. Reporting parameters such as Burst Spread when entering the RRC connection state will increase service transmission latency. Therefore, it is necessary to optimize the UE's parameter reporting or preference process.

[0130] Therefore, the embodiments of the present application propose:

[0131] The UE reports the first parameter in a random access uplink message (eg, MSG3 or MSGA).

[0132] The first parameter may include, for example, one or more parameters selected from burst spread, delay jitter, service characteristics, and UE energy saving preferences;

[0133] Optionally, the random access uplink message is a media access control element MAC CE or a radio resource control RRC message.

[0134] Alternatively, see Figure 5 , the random access uplink message includes logical channel (LCH) information or data resource block DRB information, and the correspondence with the first parameter.

[0135] Optionally, the UE determines whether to report the first parameter according to an instruction from the network side;

[0136] Optionally, the network side indication may be carried in a broadcast message, that is, information is added to the broadcast message to indicate whether the UE reports the first parameter;

[0137] Optionally, the network side indication may also be an RRC release message;

[0138] Optionally, before the UE reports the first parameter, it is determined whether the current MSG3 / MSGA size can carry the first parameter. If so, the first parameter is sent; if the first parameter cannot be carried, the UE may carry a buffer status report (BSR) in the MSG3 / MSGA or segment the first parameter (that is, originally sending a complete data packet, now the data packet is segmented. Note that the data packet here may be a PDCP data packet);

[0139] Optionally, the network side reserves a physical layer random access channel (PRACH) resource for the first parameter (but not for transmitting the first parameter). When the UE needs to report the first parameter in MSGA / MSG3, the UE selects the preamble or PRACH time slot or MSGA resource in the reserved PRACH resource to perform data transmission. After that, the first parameter can be sent through Msg3.

[0140] Optionally, the network side carries a security parameter (such as a Next Hop Chaining Count (NCC) parameter) in an RRC Release message to the UE. The UE encrypts the MSG3 / MSGA according to the security parameter and sends the result to the network side.

[0141] Optionally, when the first data resource block (DRB) data arrives, the UE autonomously triggers the above-mentioned reporting process, and the first DRB may be configured on the network side.

[0142] Example 1: The UE reports the first parameter in MSG3.

[0143] Step 0: The UE determines to send the first parameter in MSG3.

[0144] Optionally, the UE determines to send the first parameter in MSG3 according to an instruction from the network side.

[0145] Optionally, the network-side indication may be an indication in a broadcast message of whether the cell to which the UE is attached supports the UE reporting the first parameter in MSG3.

[0146] Optionally, the network side indication may be an indication in the RRC Release message, and the network side indication is valid when the UE does not leave the current cell in the idle state (IDLE) and / or when the UE is in the active (Inactive) state and does not leave the random access network (RAN) area (area).

[0147] Step 1: The UE selects a preamble and sends the selected preamble on the PRACH resource.

[0148] Optionally, the network side configures a Preamble resource for reporting the first parameter.

[0149] Optionally, the network side may notify the preamble of the first parameter and the PRACH resource in a broadcast message or an RRC Release message.

[0150] Step 2: The UE receives the RAR sent by the network side.

[0151] The RAR carries the UL grant of MSG3.

[0152] The UL authorization of MSG3 is determined by the network side according to the preamble sent by the UE, and the UE will send the first parameter calculation in MSG3.

[0153] Step 3: After receiving the RAR, the UE sends the first parameter in the UL authorization used to send the MSG3.

[0154] The first parameter may be one or a combination of the following parameters:

[0155] Burst spread parameters, UE energy saving preferences, service period and packet size, etc. The burst spread parameters may be one or more parameters selected from the group consisting of service arrival delay jitter, service maximum delay, service data packet size mean, and service data packet size variance.

[0156] The UE energy saving preference may include one or a combination of the following parameters: Discontinuous Reception (DRX) parameters, bandwidth preference, number of Multiple Input Multiple Output (MIMO) layers, etc.

[0157] Optionally, the MSG3 is encrypted and integrity protected, and the encryption key is calculated by the next hop chaining count (NCC) configured on the network side.

[0158] Optionally, when the UL grant cannot carry the first parameter, that is, when the UL grant size is smaller than the first parameter size, the UE may carry the BSR in the MSG3.

[0159] Step 4: The UE receives MSG4 sent by the network side.

[0160] The MSG4 includes a contention resolution media access control element (MAC CE) and an RRC confirmation message sent by the network. If the UE is performing an RRC establishment procedure, the network responds with an RRC setup message; if the UE is performing an RRC resume procedure, the network sends an RRC resume message.

[0161] Example 2: The UE reports service-related parameters in MSGA.

[0162] Step 0: The UE determines to send the first parameter in the MSGA.

[0163] Optionally, the UE determines to send the first parameter in the MSGA according to an instruction from the network side.

[0164] Optionally, the network-side indication may be information in a broadcast message indicating whether the cell to which the UE is attached supports the UE reporting the first parameter in the MSGA.

[0165] Optionally, the network side indication may be an indication in an RRC Release message, and the network side indication is valid when the UE does not leave the current cell in IDLE state and / or the UE does not leave the RAN area when in Inactive state.

[0166] Step 1: The UE selects an MSGA resource and sends the selected MSGA on the selected MSGA resource.

[0167] Optionally, the network side configures an MSGA resource for reporting the first parameter.

[0168] Optionally, the network side may notify the MSGA resources of the first parameter in a broadcast message or an RRC Release message.

[0169] The MSGA includes a Preamble resource and a PUSCH resource, and the UE sends the first parameter on the PUSCH resource:

[0170] Burst spread parameters, UE energy saving preferences, service cycle, and packet size, etc.

[0171] The energy-saving preferences may include: DRX parameters, bandwidth preference, number of MIMO layers, etc.

[0172] Optionally, the MSGA is encrypted and integrity protected, and the key used for encryption is calculated by the NCC configured on the network side.

[0173] Optionally, when the UL grant cannot carry the first parameter, that is, when the UL grant size is smaller than the first parameter size, the UE may carry the BSR in the MSGA.

[0174] Step 2: The UE receives the RAR sent by the network side. The RAR can be either a Fallback RAR or a Success RAR.

[0175] If it is successRAR, it means that the network side has successfully received MSGA. Since the successRAR already carries the UE's cell radio network temporary identifier (Cell-Radio Network Temporary Identifier, C-RNTI), the UE can use the C-RNTI to receive feedback from the network side after receiving the successRAR.

[0176] If it is a fallbackRAR, the fallbackRAR will carry a UL grant, and the UE will send the first parameter in the UL grant. When the UL grant size is inconsistent with the PUSCH size in the MSGA, the UE will re-perform the packet assembly.

[0177] The feedback from the network side includes an RRC confirmation message sent by the network side. If the UE performs the RRC establishment process, the network side replies with an RRC setup message. If the UE performs the RRC resume process, the network side sends an RRC resume message.

[0178] In summary, see Figure 6 On the terminal side, an information transmission method provided by an embodiment of the present application includes:

[0179] S101. A terminal determines a first parameter, where the first parameter is used to indicate a service delay requirement and / or delay jitter requirement of the terminal;

[0180] S102. The terminal sends the first parameter through a random access uplink message.

[0181] Optionally, the first parameter includes one or a combination of the following parameters:

[0182] Burst spread, delay jitter, service characteristics, and UE energy-saving preferences.

[0183] Optionally, when an indication of reporting the first parameter sent by the network side is received, the first parameter is sent, and the indication is carried by a broadcast message or a radio resource control release RRC Release message.

[0184] Optionally, if the current random access uplink message size can carry the first parameter, the first parameter is sent.

[0185] Optionally, if the current random access uplink message size cannot carry the first parameter, the method further includes:

[0186] Sending a buffer status report BSR via a random access uplink message;

[0187] Alternatively, segmenting the first parameter to obtain a first parameter segment, and sending the first parameter segment through a random access uplink message;

[0188] Alternatively, the BSR and the first parameter segment obtained by segmenting the first parameter are sent through a random access uplink message.
