Application scenarios of future wireless communication systems are becoming increasingly diversified, and different application scenarios have different performance demands on systems. In order to meet different performance requirements of various application scenarios, 3rd Generation Partner Project (3GPP) Radio Access Network (RAN) #72 plenary decided to conduct the study of New Radio (NR), or what is called fifth Generation (5G). A work Item (WI) of NR was approved at 3GPP RAN #75 plenary to standardize NR.

In communications, whether Long Term Evolution (LTE) or 5G NR involves features of accurate reception of reliable information, optimized energy efficiency ratio, determination of information efficiency, flexible resource allocation, scalable system structure, efficient non-access layer information processing, low service interruption and dropping rate and support for low power consumption, which are of great significance to the maintenance of normal communications between a base station and a UE, reasonable scheduling of resources and balancing of system payload. Those features can be called the cornerstone of high throughout and are characterized in meeting communication requirements of various service, improving spectrum utilization and improving service quality, which are indispensable in enhanced Mobile BroadBand (eMBB), Ultra Reliable Low Latency Communications (URLLC) and enhanced Machine Type Communications (eMTC). Meanwhile, in the following communication modes, covering Industrial Internet of Things (IIoT), Vehicular to X (V2X), Device to Device communications, Unlicensed Spectrum communications, User communication quality monitoring, network planning optimization, Non-Territorial Networks (NTN), Territorial Networks (TN), and Dual connectivity system, there are extensive requirements in radio resource management and selection of multi-antenna codebooks as well as in signaling design, adjacent cell management, service management and beamforming. Transmission methods of information are divided into broadcast transmission and unicast transmission, both of which are essential for 5G system for that they are very helpful to meet the above requirements. The UE can be connected to the network directly or through a relay.

With the increase of scenarios and complexity of systems, higher requirements are raised for interruption rate and time delay reduction, reliability and system stability enhancement, service flexibility and power saving. At the same time, compatibility between different versions of different systems should be considered when designing the system.

3GPP standardization organization has carried out relevant standardization work for 5G and formed a series of standards, which can be referred to as follows:

SUMMARY

In the communication system, a research project on XR traffic is added in version 18 of 3GPP. XR traffic comprises Virtual Reality (VR) traffic, Augmented Reality (AR) traffic, and Cloud Games (CG) traffic, which has the characteristics of high speed and low latency, and at the same time, has strict requirements for traffic response time for being interactive service. On the one hand, XR traffic often involves high-speed and high-definition time-frequency transmission, which consumes a lot of power and requires support for Discontinuous Reception (DRX) to save electricity; on the other hand, due to the inherent attributes and requirements of an arrival of traffic data, for example, data of one type of traffic may need to be transmitted every 16.67 milliseconds, while the existing DRX mechanism cannot adapt to such requirements. If an approximate value is used, a user is awakened every 16 milliseconds, then after a period of accumulation, the occasion of waking up and an actual time to transmit the traffic will become increasingly staggered, which means that the user need to wait for a long time to receive traffic data after waking up, in the case, a DRX will be difficult to save power. Therefore, it is necessary to design a matching power-saving mechanism for XR or traffic with similar requirements to support, such as a non-integral transmission cycle. Researchers have found that if multiple DRX cycles are configured, such as mixing 16 ms and 17 ms DRX cycles, or multiple active time windows are configured through templates within a longer cycle, such as configuring 3 active time windows within 50 ms, more flexible DRX cycle can be achieved, such as a DRX cycle of 16.67 ms. However, the DRX cycle involves other aspects besides power saving effect. In a signal measurement, the DRX cycle is an important parameter that affects a series of measurement indicators and behavior of the measurement, which can lead to inconsistency between the terminal and the network if ambiguity or confusion occurs, thereby affecting performance and even causing dropped calls. For example, if both 16 ms and 17 ms DRX cycles are configured, this inconsistency will occur if the terminal uses 16 ms while the network considers it to be 16.67 ms. Therefore, how to enable the signal measurement function to support a new DRX and further support XR traffic is a problem that needs to be addressed.

To address the above problem, the present application provides a solution.

Embodiment 3

Embodiment 3 illustrates a schematic diagram of an example of a radio protocol architecture of a user plane and a control plane according to one embodiment of the present application, as shown in FIG. 3. FIG. 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture of a user plane 350 and a control plane 300. In FIG. 3, the radio protocol architecture for a first node (UE, gNB or a satellite or an aircraft in NTN) and a second node (gNB, UE or a satellite or an aircraft in NTN), or between two UEs is represented by three layers, which are a layer 1, a layer 2 and a layer 3, respectively. The layer 1 (L1) is the lowest layer and performs signal processing functions of various PHY layers. The L1 is called PHY 301 in the present application. The layer 2 (L2) 305 is above the PHY 301, and is in charge of a link between a first node and a second node, as well as two UEs via the PHY 301. L2 305 comprises a Medium Access Control (MAC) sublayer 302, a Radio Link Control (RLC) sublayer 303 and a Packet Data Convergence Protocol (PDCP) sublayer 304. All the three sublayers terminate at the second node. The PDCP sublayer 304 provides multiplexing among variable radio bearers and logical channels. The PDCP sublayer 304 provides security by encrypting a packet and provides support for a first node handover between second nodes. The RLC sublayer 303 provides segmentation and reassembling of a higher-layer packet, retransmission of a lost packet, and reordering of a data packet so as to compensate the disordered receiving caused by HARQ. The MAC sublayer 302 provides multiplexing between a logical channel and a transport channel. The MAC sublayer 302 is also responsible for allocating between first nodes various radio resources (i.e., resource block) in a cell. The MAC sublayer 302 is also in charge of HARQ operation. The Radio Resource Control (RRC) sublayer 306 in layer 3(L3) of the control plane 300 is responsible for acquiring radio resources (i.e., radio bearer) and configuring the lower layer with an RRC signaling between a second node and a first node. PC5 Signaling Protocol (PC5-S) sublayer 307 is responsible for the processing of signaling protocol at PC5 interface. The radio protocol architecture of the user plane 350 comprises layer 1 (L1) and layer 2 (L2). In the user plane 350, the radio protocol architecture for the first node and the second node is almost the same as the corresponding layer and sublayer in the control plane 300 for physical layer 351, PDCP sublayer 354, RLC sublayer 353 and MAC sublayer 352 in L2 layer 355, but the PDCP sublayer 354 also provides a header compression for a higher-layer packet so as to reduce a radio transmission overhead. The L2 layer 355 in the user plane 350 also includes Service Data Adaptation Protocol (SDAP) sublayer 356, which is responsible for the mapping between QoS flow and Data Radio Bearer (DRB) to support the diversity of traffic. SRB can be seen as a service or interface provided by the PDCP layer to a higher layer, such as the RRC layer. In NR system, SRB comprises SRB1, SRB2, SRB3, and when it comes to sidelink communications, there is also SRB4, which is respectively used to transmit different types of control signalings SRB, a bearer between a UE and access network, is used to transmit a control signaling, comprising an RRC signaling, between UE and access network. SRB1 has special significance for a UE. After each UE establishes an RRC connection, there will be SRB1 used to transmit RRC signaling Most of the signalings are transmitted through SRB1. If SRB1 is interrupted or unavailable, the UE must perform RRC reconstruction. SRB2 is generally used only to transmit an NAS signaling or signaling related to security aspects. UE cannot configure SRB3. Except for emergency services, a UE must establish an RRC connection with the network for subsequent communications. Although not described in the figure, the first node may comprise several higher layers above the L2 305. also comprises a network layer (i.e., IP layer) terminated at a P-GW 213 of the network side and an application layer terminated at the other side of the connection (i.e., a peer UE, a server, etc.). For UE involving relay service, its control plane can also comprise the adaptation sub-layer Sidelink Relay Adaptation Protocol (SRAP) 308, and its user plane can also comprise the adaptation sub-layer SRAP358, the introduction of the adaptation layer helps lower layers, such as MAC layer, RLC layer, to multiplex and/or distinguish data from multiple source UEs. For nodes that do not involve relay communications, PC5-S307, SRAP308 and SRAP358 are not required in the communication process.

Embodiment 4

FIG. 4 is a block diagram of a first communication device 450 in communication with a second communication device 410 in an access network.

The first communication device 450 comprises a controller/processor 459, a memory 460, a data source 467, a transmitting processor 468, a receiving processor 456, optionally may also comprise a multi-antenna transmitting processor 457, a multi-antenna receiving processor 458, a transmitter/receiver 454 and an antenna 452.

The second communication device 410 comprises a controller/processor 475, a memory 476, a receiving processor 470, a transmitting processor 416, optional can also comprise a multi-antenna receiving processor 472, a multi-antenna transmitting processor 471, a transmitter/receiver 418 and an antenna 420.

In a transmission from the second communication device 410 to the first communication device 450, at the first communication device 410, a higher layer packet from the core network is provided to a controller/processor 475. The controller/processor 475 provides a function of the L2 layer. In the transmission from the second communication device 410 to the first communication device 450, the controller/processor 475 provides header compression, encryption, packet segmentation and reordering, and multiplexing between a logical channel and a transport channel, and radio resources allocation for the first communication device 450 based on various priorities. The controller/processor 475 is also responsible for retransmission of a lost packet and a signaling to the first communication device 450. The transmitting processor 416 and the multi-antenna transmitting processor 471 perform various signal processing functions used for the L1 layer (that is, PHY). The transmitting processor 416 performs coding and interleaving so as to ensure an FEC (Forward Error Correction) at the second communication device 410, and the mapping to signal clusters corresponding to each modulation scheme (i.e., BPSK, QPSK, M-PSK, M-QAM, etc.). The multi-antenna transmitting processor 471 performs digital spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming on encoded and modulated symbols to generate one or more spatial streams. The transmitting processor 416 then maps each spatial stream into a subcarrier. The mapped symbols are multiplexed with a reference signal (i.e., pilot frequency) in time domain and/or frequency domain, and then they are assembled through Inverse Fast Fourier Transform (IFFT) to generate a physical channel carrying time-domain multi-carrier symbol streams. After that the multi-antenna transmitting processor 471 performs transmission analog precoding/beamforming on the time-domain multi-carrier symbol streams. Each transmitter 418 converts a baseband multicarrier symbol stream provided by the multi-antenna transmitting processor 471 into a radio frequency (RF) stream. Each radio frequency stream is later provided to different antennas 420.

In a transmission from the second communication device 410 to the first communication device 450, at the second communication device 450, each receiver 454 receives a signal via a corresponding antenna 452. Each receiver 454 recovers information modulated to the RF carrier, converts the radio frequency stream into a baseband multicarrier symbol stream to be provided to the receiving processor 456. The receiving processor 456 and the multi-antenna receiving processor 458 perform signal processing functions of the L1 layer. The multi-antenna receiving processor 458 performs receiving analog precoding/beamforming on a baseband multicarrier symbol stream from the receiver 454. The receiving processor 456 converts the baseband multicarrier symbol stream after receiving the analog precoding/beamforming from time domain into frequency domain using FFT. In frequency domain, a physical layer data signal and a reference signal are de-multiplexed by the receiving processor 456, wherein the reference signal is used for channel estimation, while the data signal is subjected to multi-antenna detection in the multi-antenna receiving processor 458 to recover any the first communication device-targeted spatial stream. Symbols on each spatial stream are demodulated and recovered in the receiving processor 456 to generate a soft decision. Then the receiving processor 456 decodes and de-interleaves the soft decision to recover the higher-layer data and control signal transmitted on the physical channel by the second communication node 410. Next, the higher-layer data and control signal are provided to the controller/processor 459. The controller/processor 459 performs functions of the L2 layer. The controller/processor 459 can be connected to a memory 460 that stores program code and data. The memory 460 can be called 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 a transport channel and a logical channel, packet reassembling, decryption, header decompression and control signal processing so as to recover a higher-layer packet from the core network. The higher-layer packet is later provided to all protocol layers above the L2 layer, or various control signals can be provided to the L3 layer for processing.

In a transmission from the first communication device 450 to the second communication device 410, at the second communication device 450, the data source 467 is configured to provide a higher-layer packet to the controller/processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to a transmitting function of 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 performs header compression, encryption, packet segmentation and reordering, and multiplexing between a logical channel and a transport channel based on radio resources allocation so as to provide the L2 layer functions used for the user plane and the control plane. The controller/processor 459 is also responsible for retransmission of a lost packet, and a signaling to the second communication device 410. The transmitting processor 468 performs modulation mapping and channel coding. The multi-antenna transmitting processor 457 implements digital multi-antenna spatial precoding, including codebook-based precoding and non-codebook-based precoding, as well as beamforming. Following that, the generated spatial streams are modulated into multicarrier/single-carrier symbol streams by the transmitting processor 468, and then modulated symbol streams are subjected to analog precoding/beamforming in the multi-antenna transmitting processor 457 and provided from the transmitters 454 to each antenna 452. Each transmitter 454 first converts a baseband symbol stream provided by the multi-antenna transmitting processor 457 into a radio frequency symbol stream, and then provides the radio frequency symbol stream to the antenna 452.

In the transmission from the first communication device 450 to the second communication device 410, the function at the second communication device 410 is similar to the receiving function at the first communication device 450 described in the transmission from the second communication device 410 to the first communication device 450. Each receiver 418 receives a radio frequency signal via a corresponding antenna 420, converts the received radio frequency signal into a baseband signal, and provides the baseband signal to the multi-antenna receiving processor 472 and the receiving processor 470. The receiving processor 470 and multi-antenna receiving processor 472 collectively provide functions of the L1 layer. The controller/processor 475 provides functions of the L2 layer. The controller/processor 475 can be connected with the memory 476 that stores program code and data. The memory 476 can be called a computer readable medium. In the transmission from the first communication device 450 to the second communication device 410, the controller/processor 475 provides de-multiplexing between a transport channel and a logical channel, packet reassembling, decryption, header decompression, control signal processing so as to recover a higher-layer packet from the UE 450.
