- the network device does not have an access stratum (AS) context for the terminal device, and no connection is established between the network device and the core network for that terminal device.
- AS access stratum
- the terminal device needs to transition from RRC idle state to RRC connected state, it needs to initiate an RRC connection establishment process.
- the core network can send paging messages to the terminal device; that is, the paging process can be triggered by the CN.
- the paging area can also be configured by the CN.
- the terminal device can initiate a cell reselection process.
- the terminal device can initiate a cell selection process.
- mobility management for a terminal device in RRC idle state can include cell reselection and/or cell selection.

- the user plane protocol stack of a communication system can be divided into multiple sub-layers. Taking the NR system as an example, the user plane protocol stack of the NR system can be divided into four sub-layers, which, from bottom to top, are the medium access control (MAC) layer, the radio link control (RLC) layer, the packet data convergence protocol layer, and the packet data convergence protocol layer. PDCP layer, Service Data Adaptation Protocol (SDAP) layer.
- MAC medium access control
- RLC radio link control
- SDAP Service Data Adaptation Protocol
- the MAC layer is responsible for one or more of the following functions: mapping between logical channels and transport channels, multiplexing between logical channels and transport channels, demultiplexing between logical channels and transport channels, uplink and downlink scheduling procedures, random access procedures, etc.
- mapping between logical channels and transport channels multiplexing between logical channels and transport channels
- demultiplexing between logical channels and transport channels uplink and downlink scheduling procedures, random access procedures, etc.
- the MAC layer in NR systems introduces some new features, such as the activation/deactivation procedure of the bandwidth part (BWP) and the beam failure recovery procedure.
- BWP bandwidth part
- the RLC layer is responsible for one or more of the following functions: packet segmentation, packet reassembly, error detection, etc. Unlike LTE systems, the RLC layer in NR systems does not include packet concatenation functionality.
- the PDCP layer is responsible for one or more of the following functions: packet encryption, packet decryption, integrity protection, header compression, sequence number maintenance, reordering, and in-order delivery.
- the PDCP layer in NR systems can support out-of-order delivery based on network configuration.
- the PDCP layer in NR systems can also support functions such as data duplication (or data replication) to improve the reliability of data packet transmission.
- the SDAP layer is primarily responsible for mapping between Quality of Service (QoS) streams and data radio bearers (DRBs).
- QoS Quality of Service
- DRBs data radio bearers
- user plane data first arrives at the SDAP layer via QoS streams.
- the SDAP layer is responsible for mapping data from different QoS streams to different DRBs and adding QoS stream identifiers to the data according to network configuration, generating SDAP packet data units (PDUs) and submitting them to the PDCP layer.
- the PDCP layer processes the SDAP PDUs (e.g., header compression, encryption, integrity protection) and generates PDCP PDUs, which are then submitted to the RLC layer.
- the RLC layer processes RLC service data units (SDUs) according to the configured RLC mode, such as RLC SDU segmentation and retransmission management.
- SDUs RLC service data units
- the MAC layer is responsible for multiplexing the data from the logical channel into a MAC PDU (also called a transport block (TB)).
- This MAC PDU can include multiple RLC SDUs or segments of RLC SDUs. These RLC SDUs can come from different logical channels or from the same logical channel.
- a MAC PDU (i.e., TB) can contain one or more MAC SDUs.
- One MAC SDU can correspond to a complete RLC SDU or a segment of an RLC SDU.
- the PDCP layer is primarily responsible for processing PDCP SDUs received from the SDAP layer. For example, it processes the received PDCP SDUs to generate PDCP PDUs, which are then delivered to the corresponding RLC layer.
- the PDCP layer is primarily responsible for receiving PDCP PDUs delivered from the RLC layer, processing them (such as removing the PDCP header), and then delivering them to the SDAP layer.
- the PDCP layer provides one or more of the following functions: maintenance of the PDCP sender's sequence number (SN), maintenance of the PDCP receiver's SN, packet header compression and decompression, packet encryption and decryption, packet integrity protection, timer-based PDCP SDU discarding, routing in split bearer scenarios, copy transmission, reordering, and in-order delivery.
- SN sequence number
- PDCP receiver's SN packet header compression and decompression
- packet encryption and decryption packet integrity protection
- timer-based PDCP SDU discarding routing in split bearer scenarios, copy transmission, reordering, and in-order delivery.
- the PDCP transmitter can maintain a local counter value of TX_NEXT (such as a COUNT value). This counter value can be initially set to 0. Each time a new PDCP PDU is generated, the SN in the corresponding header is set to the value corresponding to TX_NEXT, and TX_NEXT is incremented by 1. TX_NEXT indicates the SN of the next PDCP PDU to be constructed. Furthermore, the PDCP transmitter can sequentially perform header compression, integrity protection, and encryption operations on the PDCP SDU according to the network configuration. For downlink reception, the PDCP receiver can maintain a receive window based on the local counter value. This receive window can be maintained by the following local variables: RX_NEXT, RX_DELIV, and RX_REORD.
- RX_NEXT indicates the count value corresponding to the next expected PDCP SDU.
- RX_DELIV indicates the count value corresponding to the next PDCP SDU expected to be sent uplink.
- the RX_DELIV variable can be used to determine the lower boundary of the receive window.
- RX_REORD indicates the count value corresponding to the PDCP PDU that triggered the sorting timer.
- NR systems use an absolute count-based method for maintaining local variables and performing conditional comparisons during data transmission and reception. This improves protocol readability.
- the count consists of a serial number (SN) and a superframe number, with a fixed size of 32 bits.
- SN serial number
- superframe number a serial number
- the header of the PDCP PDU still includes the SN, not the count, thus avoiding increased overhead for air interface transmission.
- the RLC layer is located between the PDCP layer and the MAC layer. It can process the PDU data of the PDCP layer into SDU and then hand it over to the MAC layer.
- the RLC layer provides three transmission modes for different types of data: transparent mode (TM), unacknowledge mode (UM), and acknowledge mode (AM).
- TM transparent mode
- UM unacknowledge mode
- AM acknowledge mode
- TM the RLC layer does not process data and directly delivers it to the MAC layer. Therefore, TM processing is the simplest and most efficient. TM is mainly used for the transmission of paging messages, system information broadcasts, and signaling radio bearer 0 (SRB 0).
- UM can also be called unreliable mode.
- the RLC layer does not perform ARQ processing.
- UM does not support retransmission and is generally suitable for services that do not have high requirements for data reliability but are sensitive to latency.
- UM can be used for the transmission of services with high real-time requirements such as audio DRB and video.
- UM while not guaranteeing correct transmission, is more complex.
- the sender needs to segment (if necessary) and add headers to the RLC SDU to construct the UM data PDU (UM data PDU, UMD PDU).
- the receiver needs to remove the header and reassemble the UMD PDU (if necessary). Segmentation and reassembly are necessary because the MAC entity informs the UM RLC entity of the MAC layer's acceptable UMD PDU size limit. Due to this size limit, for excessively large RLC SDUs, a single PDU might not contain a complete SDU when constructing it into a UMD PDU. Therefore, the RLC SDU needs to be segmented into multiple RLC SDU segments.
- Each PDU's data field contains only one RLC SDU segment, and a header is added to construct the UMD PDU before sending it to the MAC layer for transmission.
- segmentation/reassembly and header addition/removal are the main differences between UM and TM.
- AM can also be called Reliable Mode.
- the RLC layer provides full-featured processing.
- the RLC has the functionality of UM (Unified Management Module) and also supports data reception status feedback. Because retransmissions exist in AM, transmission efficiency is lower. That is, AM supports retransmissions based on status feedback reports, ensuring data transmission reliability but increasing data transmission latency.
- AM is suitable for dedicated control and dedicated services, generally requiring high reliability. For example, AM can be applied to SRBs other than SRB 0, file transfer protocol (FTP), web browsing, and other error-sensitive services.
- FTP file transfer protocol
- AM RLC entities Similar to UM, AM RLC entities also perform segmentation and reassembly, as well as header addition and removal, when necessary. Unlike TM/UM, AM ensures the correctness of data transmission, so the sender must retransmit as needed based on the receiver's reception status.
- the RLC layer can provide one or more of the following functions: segmentation, concatenation and reassembly of RLC SDUs, reordering of RLC SDUs, error correction based on automatic repeat reQuest (ARQ), filtering of duplicate packets of received RLC SDUs, resegmentation, and discarding of RLC SDUs.
- segmentation concatenation and reassembly of RLC SDUs
- reordering of RLC SDUs reordering of RLC SDUs
- ARQ automatic repeat reQuest
- the RLC layer provides functionalities applicable to different transmission modes. These are described below.
- RLC layer segmentation, concatenation, and reassembly of RLC SDUs can be applied to UM and AM.
- RLC layer segmentation, concatenation, and reassembly of RLC SDUs can be understood as the RLC layer combining multiple PDCP layer PDUs into a single SDU for transmission.
- the RLC layer's reordering of received RLC SDUs can be applied to UM and AM.
- the RLC layer can be applied to AM through ARQ error correction.
- Duplicate packets of RLC SDUs received by the RLC layer can be applied to AM, where the duplicate packets are caused by retransmission.
- RLC layer resegmentation can be applied in AM.
- RLC layer resegmentation can refer to the RLC layer resegmenting retransmitted packets.
- RLC SDU discarding can be applied to AM and UM.
- Radio bearers are used by network devices to allocate different layer protocol entities and configurations to terminal devices. These can include PDCP entities, RLC entities, MAC entities, and resources allocated by the physical layer. Radio bearers can include DRBs and signaling radio bearers (SRBs).
- PDCPs and radio bearers can be in one-to-one correspondence, meaning that each radio bearer can be associated with a PDCP entity.
- Terminal devices in a multi-radio access technology dual connectivity (MR-DC) configuration have three types of radio bearers: master cell group bearer (MCG bearer), secondary cell group bearer (SCG bearer), and separate bearer.
- MCG bearer master cell group bearer
- SCG bearer secondary cell group bearer
- separate bearer separate bearer
- the radio bearer When the RLC, MAC, and physical protocol stack (the protocol stack can also be understood as a protocol layer or protocol entity, which will not be elaborated on later) of a radio bearer are located on the master node (MN), the radio bearer is called an MCG bearer.
- the radio bearer When the RLC, MAC, and physical protocol stack of a radio bearer are located on a secondary node (SN), the radio bearer is called an SCG bearer.
- the split bearer has radio links on both the MN and SN, but only one PDCP protocol stack.
- the PDCP protocol stack is located on the MN side. In other embodiments, the PDCP protocol stack is located on the SN side.
- the purpose of the split bearer is to improve the traffic of the radio interface. In some cases, for example, when the PDCP layer allows retransmission of PDCP packets between different links, the split bearer can also improve the reliability of the radio bearer.
- its associated PDCP entity can be associated with two RLC entities.
- One RLC entity serves as the primary path, and the other as the secondary path.
- data packets from the same radio bearer can only undergo serial processing within the current protocol stack.
- data packets from the same radio bearer can only undergo parallel processing on the primary and secondary paths in scenarios involving repeated transmissions; otherwise, only the primary path performs serial processing.
- protocol stack design is based on the existing protocol stack architecture, with functional enhancements and optimizations made to the current protocol stack for new service types.
- the PDCP layer introduces a retransmission mechanism.
- This design approach has driven the construction of a unified protocol stack architecture that can cover various transmission needs, but this design approach has some drawbacks.
- the size and complexity of the protocol stack will continue to increase.
- the current protocol stack design cannot meet the transmission characteristics and requirements of different scenarios. For example, the headers of each protocol layer are designed according to the functions and processes they support, which results in inconsistent header lengths between different protocol layers.
- the header length of the MAC layer is 2-5 bytes
- the header length of the RLC layer is 0-5 bytes
- the header length of the PDCP layer is 2-3 bytes.
- one protocol stack can handle low-data-rate services and control plane (CP) processes, while the other protocol stack can handle high-data-rate services.
- CP control plane
- Figure 3 illustrates two protocol stacks.
- the two protocol stacks can include an anchor protocol stack (APS) and a fast protocol stack (FPS).
- APS anchor protocol stack
- FPS fast protocol stack
- some communication systems may associate a single radio bearer with multiple protocol layer entities or groups of protocol layer entities to support multiple parallel data processing methods.
- FPS Fast Per Second
- RPUs radio processing units
- one RPU may correspond to one PDCP entity, one RLC entity, and one MAC entity.
