BACKGROUND
Technical Field

The present application relates to transmission methods and devices in wireless communication systems, and in particular to a multi-carrier transmission scheme and device in wireless communications.

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, the 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). The work Item (WI) of NR was approved at the 3GPP RAN #75 plenary to standardize the NR.

The multi-carrier (including Carrier Aggregation, abbreviated as CA, and Dual Connectivity, abbreviated as DC) techniques is an integral part of New Radio (NR) technology. To adapt to diverse application scenarios and meet different requests, the 3GPP has been working on the evolution of multi-carrier techniques since from the Rel-15.

SUMMARY

In the multi-carrier communications, for instance Carrier Aggregation (CA), Cross Carrier Scheduling is supported. In networks supported by the existing standard, such as 5G New Radio (NR) in R17 and of previous versions, for multiple scheduled carriers, scheduling is only supported to be provided on carriers or Physical Downlink Control Channels (PDCCHs) respectively corresponding to the carriers, rather than through a same PDCCH on a same carrier.

To address the issue that a same PDCCH schedules multiple carriers simultaneously in a multicarrier system in NR, the present application discloses a solution. It should be noted that in the description of the present application, PDCCH scheduling in multicarriers is only used as an exemplary application scenario or example; this disclosure is equally applicable to other scenarios confronting similar problems, such as other scenarios having higher demands on the capacity of control channels, which include but are not limited to capacity enhancement system, the system using higher frequency, coverage enhancement system, Unlicensed Spectrum communication, the Internet of Things (IoT), Ultra Reliable Low Latency Communications (URLLC) network and Vehicle-to-Everything (V2X), where similar technical effects can be achieved. Additionally, the adoption of a unified solution for various scenarios, including but not limited to multi-carrier scenarios, contributes to the reduction of hardcore complexity and costs. In the case of no conflict, the embodiments of a first node and the characteristics in the embodiments may be applied to a second node, and vice versa. Particularly, for interpretations of the terminology, nouns, functions and variables (unless otherwise specified) in the present application, refer to definitions given in TS36 series, TS38 series and TS37 series of 3GPP specifications.

Embodiment 3

Embodiment 3 illustrates a schematic diagram of a radio protocol architecture of a user plane and a control plane according to 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 control plane 300 used for a first node (UE or gNB) and a second node (gNB or UE) is represented by three layers, which are layer 1, layer 2 and layer 3. The layer 1 (L1) is the lowest layer which 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 the link between a first node and a second node via the PHY 301. The 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 these sublayers terminate at the second nodes. The PDCP sublayer 304 provides multiplexing among variable radio bearers and logical channels. The PDCP sublayer 304 provides security by encrypting packets and also support for inter-cell handover of the first node 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 packet so as to compensate the disordered receiving caused by Hybrid Automatic Repeat reQuest (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. In the control plane 300, The RRC sublayer 306 in the L3 layer is responsible for acquiring radio resources (i.e., radio bearer) and configuring the lower layer using an RRC signaling between the second node and the first node. The radio protocol architecture in the user plane 350 comprises the L1 layer and the L2 layer. In the user plane 350, the radio protocol architecture used for the first node and the second node in a PHY layer 351, a PDCP sublayer 354 of the L2 layer 355, an RLC sublayer 353 of the L2 layer 355 and a MAC sublayer 352 of the L2 layer 355 is almost the same as the radio protocol architecture used for corresponding layers and sublayers in the control plane 300, but the PDCP sublayer 354 also provides header compression used for higher-layer packet to reduce radio transmission overhead. The L2 layer 355 in the user plane 350 also comprises a Service Data Adaptation Protocol (SDAP) sublayer 356, which is in charge of the mapping between QoS streams and a Data Radio Bearer (DRB), so as to support diversified traffics. Although not described in FIG. 3, the first node may comprise several higher layers above the L2 355, such as 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.).

In Downlink (DL), a higher layer packet, for instance higher-layer information contained in the first information block and the second information block in the present application is provided to the controller/processor 440. The controller/processor 440 provides functions of the L2 layer and above. In DL, the controller/processor 440 provides header compression, encryption, packet segmentation and reordering, multiplexing between a logical channel and a transport channel as well as radio resources allocation for the first node 450 based on various priorities. The controller/processor 440 is also responsible for HARQ operation, a retransmission of a lost packet and a signaling to the first node 450, for instance, higher-layer information contained in the first information block and the second information block is generated in the controller/processor 440. The transmitting processor 415 performs various signal processing functions used for the L1 (that is, PHY), including coding, interleaving, scrambling, modulating, power control/allocating, pre-coding and physical layer control signaling generation, for example, the generations of a physical-layer signal of the first information block and the second information block in the present application and a physical-layer signal corresponding to the PDCCH candidates in the present application are completed in the transmitting processor 415. Modulation symbols that have been generated are divided into parallel streams and each of them is mapped onto a corresponding multicarrier subcarrier and/or multicarrier symbol, and then is mapped by the transmitting processor 415 to the antenna 420 via the transmitter 416 to be transmitted in the form of radio frequency signals. At the receiving end, each receiver 456 receives a radio frequency signal via a corresponding antenna 460, and recovers baseband information modulated onto a radio frequency carrier and provides the baseband information to the receiving processor 452. The receiving processor 452 performs various signal receiving processing functions used for the L1. Signal receiving processing functions include monitoring of a physical layer signal of the first information block and the second information block in the present application and PDCCH candidates, demodulating multicarrier symbols in multicarrier symbol streams based on various modulation schemes (i.e., BPSK, QPSK), then de-scrambling, decoding and de-interleaving to recover data or control signal transmitted by the second node 410 on a physical channel, and providing the data and control signal to the controller/processor 490. The controller/processor 490 is in charge of the L2 and above layers, the controller/processor 490 interprets higher-layer information comprised in the first information block and the second information block in the present application. The controller/processor can be associated with the memory 480 that stores program code and data; the memory 480 may be called a computer readable medium.

In UL transmission, which is similar to DL, higher-layer information, including that contained in the third information block in the present application, upon generation in the controller/processor 490, is through the transmitting processor 455 to perform signal transmitting processing functions used for the L1(that is, PHY), for instance, generation of physical layer signals carrying the third information block is completed in the transmitting processor 455, and are then mapped to the antenna 460 via the transmitter 456 from the transmitting processor 455 and transmitted in the form of radio frequency signals. The receiver 416 receives a radio frequency signal via a corresponding antenna 420, and each receiver 416 recovers baseband information modulated onto a radio frequency carrier and provides the baseband information to the receiving processor 412. The receiving processor 412 performs various signal reception processing functions used for L1 (i.e., PHY), including receiving a physical layer signal carrying the third information block and then providing data and/or control signal to the controller/processor 440. Functions of the L2 performed by the controller/processor 440 include interpreting higher-layer information, including interpreting higher-layer information carried in the third information block.
