Background

Future wireless communication systems have more and more diversified application scenes, and different application scenes have different performance requirements on the system. To meet the different performance requirements of various application scenarios, a New air interface technology (NR) is decided to be researched in the 3GPP (3 rd Generation Partner Project, third Generation partnership project) RAN (Radio Access Network ) #72 times of the whole meeting, and standardized Work is started on NR by the 3GPP RAN #75 times of the whole meeting through the WI (Work Item) of NR.

In communication, both LTE (Long Term Evolution ) and 5G NR can be involved in reliable accurate reception of information, optimized energy efficiency ratio, determination of information validity, flexible resource allocation, scalable system structure, efficient non-access layer information processing, lower service interruption and disconnection rate, support for low power consumption, which is significant for normal communication between a base station and a user equipment, reasonable scheduling of resources, balancing of system load, so that it can be said as high throughput, meeting communication requirements of various services, improving spectrum utilization, improving a base stone of service quality, whether embbe (ehanced Mobile BroadBand, enhanced mobile broadband), URLLC (Ultra Reliable Low Latency Communication, ultra-high reliability low latency communication) or eMTC (enhanced Machine Type Communication ) are indispensable. Meanwhile, in the internet of things in the field of IIoT (Industrial Internet of Things), in V2X (vehicle to X) communication (Device to Device) in the field of industry, in communication of unlicensed spectrum, in monitoring of user communication quality, in network planning optimization, in NTN (Non Territerial Network, non-terrestrial network communication), in TN (Territerial Network, terrestrial network communication), in dual connectivity (Dual connectivity) system, in radio resource management and codebook selection of multiple antennas, in signaling design, neighbor management, service management, and beamforming, there is a wide demand, and the transmission modes of information are broadcast and unicast, both transmission modes are indispensable for 5G system, because they are very helpful to meet the above demands.

disclosure of Invention

In communication systems, power saving and delay reduction are often contradictory, since power saving tends to require sleeping for a longer period of time, which means that traffic cannot be received in time, and how to reduce both power consumption and delay is an important issue. This is particularly important for services that require both tight latency requirements and power savings, such as XR services. XR services include VR (virtual reality) services, AR (augmented reality) and CG (cloud game) services, which have the characteristics of high rate and low delay, and are interactive services, and strict requirements on response time of the services are met. On the other hand, the arrival of traffic data has its inherent properties and requirements, e.g., data for a service may need to be sent every 16.67 milliseconds. A typical service may only require 80ms,320ms, or even longer to send. If a shorter transmission period is to be supported, for example, 16.67ms transmission is once, a shorter DRX period may be configured. Since XR traffic may last longer, doing the same during the active time of each DRX cycle, e.g. listening to PDCCH, transmitting or receiving signals, comparing power costs, and some actions, e.g. listening to some signals, e.g. paging signals, still only require as long as 80ms,320ms, if the same actions are repeated every very short cycle, it is wasteful of power. Therefore, how to design a more power-efficient DRX mechanism, which is capable of both saving power and supporting a service with a shorter transmission period, is a problem to be solved.

In view of the above problems, the present application provides a solution.

Example 3

Embodiment 3 shows a schematic diagram of an embodiment of a radio protocol architecture according to one user plane and control plane of the present application, as shown in fig. 3. Fig. 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane 350 and a control plane 300, fig. 3 shows the radio protocol architecture for the control plane 300 for a first node (UE, satellite or aerial in gNB or NTN) and a second node (gNB, satellite or aerial in UE or NTN), or between two UEs, in three layers: layer 1, layer 2 and layer 3. Layer 1 (L1 layer) is the lowest layer and implements various PHY (physical layer) signal processing functions. The L1 layer will be referred to herein as PHY301. Layer 2 (L2 layer) 305 is above PHY301 and is responsible for the links between the first node and the second node and the two UEs through PHY301. The L2 layer 305 includes a MAC (Medium Access Control ) sublayer 302, an RLC (Radio Link Control, radio link layer control protocol) sublayer 303, and a PDCP (Packet Data Convergence Protocol ) sublayer 304, which terminate at the second node. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides security by ciphering the data packets and handover support for the first node between second nodes. The RLC sublayer 303 provides segmentation and reassembly of upper layer data packets, retransmission of lost data packets, and reordering of data packets to compensate for out of order reception due to HARQ. The MAC sublayer 302 provides multiplexing between logical and transport channels. The MAC sublayer 302 is also responsible for allocating the various radio resources (e.g., resource blocks) in one cell among the first nodes. The MAC sublayer 302 is also responsible for HARQ operations. The RRC (Radio Resource Control ) sublayer 306 in layer 3 (L3 layer) in the control plane 300 is responsible for obtaining radio resources (i.e., radio bearers) and configuring the lower layers using RRC signaling between the second node and the first node. The PC5-S (PC 5Signaling Protocol ) sublayer 307 is responsible for the processing of the signaling protocol of the PC5 interface. The radio protocol architecture of the user plane 350 includes layer 1 (L1 layer) and layer 2 (L2 layer), the radio protocol architecture for the first node and the second node in the user plane 350 is substantially the same for the physical layer 351, PDCP sublayer 354 in the L2 layer 355, RLC sublayer 353 in the L2 layer 355 and MAC sublayer 352 in the L2 layer 355 as the corresponding layers and sublayers in the control plane 300, but the PDCP sublayer 354 also provides header compression for upper layer packets to reduce radio transmission overhead. Also included in the L2 layer 355 in the user plane 350 is an SDAP (Service Data Adaptation Protocol ) sublayer 356, the SDAP sublayer 356 being responsible for mapping between QoS flows and data radio bearers (DRBs, data Radio Bearer) to support diversity of traffic. SRBs can be regarded as services or interfaces provided by the PDCP layer to higher layers, e.g., RRC layer. In the NR system, SRBs include SRB1, SRB2, and SRB3, and also SRB4 when the sidelink communication is involved, which are used to transmit different types of control signaling, respectively. SRB is a bearer between the UE and the access network for transmitting control signaling including RRC signaling between the UE and the access network. SRB1 is of particular interest for UEs, where after each UE establishes an RRC connection, there is SRB1 for transmitting RRC signaling, most of the signaling is transmitted through SRB1, and if SRB1 is interrupted or unavailable, the UE must perform RRC reestablishment. SRB2 is typically used only for transmitting NAS signaling or security related signaling. The UE may not configure SRB3. In addition to emergency services, the UE must establish an RRC connection with the network for subsequent communications. Although not shown, the first node may have several upper layers above the L2 layer 355. Further included are a network layer (e.g., IP layer) terminating at the P-GW on the network side and an application layer terminating at the other end of the connection (e.g., remote UE, server, etc.). For UEs involving relay services, its control plane may also include an adaptation sublayer SRAP (Sidelink Relay Adaptation Protocol, sidelink relay adaptation may be possible) 308, and its user plane may also include an adaptation sublayer SRAP358, the introduction of which may facilitate multiplexing and/or distinguishing data from multiple source UEs by lower layers, such as the MAC layer, e.g., the RLC layer. For nodes not involved in relay communications, PC5-S307, SRAP308, SRAP358 are not required in the course of the communication.

Example 4

Embodiment 4 shows a schematic diagram of a first communication device and a second communication device according to an embodiment of the present application, as shown in fig. 4. Fig. 4 is a block diagram of a first communication device 450 and a second communication device 410 communicating with each other in an access network.

The first communication device 450 includes a controller/processor 459, a memory 460, a data source 467, a transmit processor 468, a receive processor 456, and optionally a multi-antenna transmit processor 457, a multi-antenna receive processor 458, a transmitter/receiver 454, and an antenna 452.

The second communication device 410 includes a controller/processor 475, a memory 476, a receive processor 470, a transmit processor 416, and optionally a multi-antenna receive processor 472, a multi-antenna transmit processor 471, a transmitter/receiver 418, and an antenna 420.

In the transmission from the second communication device 410 to the first communication device 450, upper layer data packets from the core network are provided to a controller/processor 475 at the second communication device 410. The controller/processor 475 implements the functionality of the L2 (Layer-2) Layer. In the transmission from the second communication device 410 to the first communication device 450, a controller/processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to the first communication device 450 based on various priority metrics. The controller/processor 475 is also responsible for retransmission of lost packets and signaling to the first communication device 450. The transmit processor 416 and the multi-antenna transmit processor 471 implement various signal processing functions for the L1 layer (i.e., physical layer). Transmit processor 416 performs coding and interleaving to facilitate Forward Error Correction (FEC) at the second communication device 410, as well as mapping of signal clusters based on various modulation schemes, e.g., binary Phase Shift Keying (BPSK), quadrature Phase Shift Keying (QPSK), M-phase shift keying (M-PSK), M-quadrature amplitude modulation (M-QAM). The multi-antenna transmit processor 471 digitally space-precodes the coded and modulated symbols, including codebook-based precoding and non-codebook-based precoding, and beamforming processing, to generate one or more spatial streams. A transmit processor 416 then maps each spatial stream to a subcarrier, multiplexes with reference signals (e.g., pilots) in the time and/or frequency domain, and then uses an Inverse Fast Fourier Transform (IFFT) to generate a physical channel carrying the time domain multicarrier symbol stream. The multi-antenna transmit processor 471 then performs transmit analog precoding/beamforming operations on the time domain multi-carrier symbol stream. Each transmitter 418 converts the baseband multicarrier symbol stream provided by the multiple antenna transmit processor 471 to a radio frequency stream and then provides it to a different antenna 420.

In a transmission from the second communication device 410 to the first communication device 450, each receiver 454 receives a signal at the first communication device 450 through its respective antenna 452. Each receiver 454 recovers information modulated onto a radio frequency carrier and converts the radio frequency stream into a baseband multicarrier symbol stream that is provided to a receive processor 456. The receive processor 456 and the multi-antenna receive processor 458 implement various signal processing functions for the L1 layer. A multi-antenna receive processor 458 performs receive analog precoding/beamforming operations on the baseband multi-carrier symbol stream from the receiver 454. The receive processor 456 converts the baseband multicarrier symbol stream after receiving the analog precoding/beamforming operation from the time domain to the frequency domain using a Fast Fourier Transform (FFT). In the frequency domain, the physical layer data signal and the reference signal are demultiplexed by the receive processor 456, wherein the reference signal is to be used for channel estimation, and the data signal is subjected to multi-antenna detection in the multi-antenna receive processor 458 to recover any spatial stream destined for the first communication device 450. The symbols on each spatial stream are demodulated and recovered in a receive processor 456 and soft decisions are generated. The receive processor 456 then decodes and deinterleaves the soft decisions to recover the upper layer data and control signals that were transmitted by the second communication device 410 on the physical channel. The upper layer data and control signals are then provided to the controller/processor 459. The controller/processor 459 implements the functions of the L2 layer. The controller/processor 459 may be associated with a memory 460 that stores program codes and data. Memory 460 may be referred to as a computer-readable medium. In the transmission from the second communication device 410 to the second communication device 450, the controller/processor 459 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, control signal processing to recover upper layer data packets from the core network. The upper layer packets are then provided to all protocol layers above the L2 layer. Various control signals may also be provided to L3 for L3 processing.

In the transmission from the first communication device 450 to the second communication device 410, a data source 467 is used at the first communication device 450 to provide upper layer data packets to a controller/processor 459. Data source 467 represents all protocol layers above the L2 layer. Similar to the transmit functions at the second communication device 410 described in the transmission from the second communication device 410 to the first communication device 450, the controller/processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on radio resource allocations, implementing L2 layer functions for the user and control planes. The controller/processor 459 is also responsible for retransmission of lost packets and signaling to the second communication device 410.
