METHOD AND DEVICE IN NODES USED FOR WIRELESS COMMUNICATION

BACKGROUND
Technical Field

The present application relates to transmission methods and devices in wireless communication systems, and in particular to a transmission scheme and device related to information with different priorities in wireless communications.

Related Art

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, it was decided at 3rd Generation Partner Project (3GPP) Radio Access Network (RAN) #72th plenary that a study on New Radio (NR), or what is called Fifth Generation (5G) shall be conducted. The work item of NR was approved at 3GPP RAN #75th plenary to standardize NR. A Study Item (SI) and a Work Item (WI) of NR Rel-17 was decided to start at 3GPP RAN #86 plenary.

In new radio technology, enhanced Mobile BroadBand (eMBB), Ultra-reliable and Low Latency Communications (URLLC), and massive Machine Type Communications (mMTC) are the three main application scenarios.

SUMMARY

In URLLC communications, there exist transmissions of data or control information with different priorities. In NR Rel-16, when Uplink Control Information (UCIs) with different priorities collide with each other in time domain, a UCI with low-priority will be dropped to ensure a transmission of a UCI with a high priority. In NR Rel-17, the multiplexing of UCIs with different priorities onto a same PUCCH or a same PUSCH is supported.

The present application discloses a solution to the multiplexing problem of UCIs associated with different priorities. It should be noted that though the present application only took URLLC for example in the statement above; the present application is also applicable to other scenarios facing similar problems (such as scenarios where multiple services coexist, or other scenarios of the multiplexing of information with different priorities, or scenarios of the multiplexing of services with different QoS requirements, or for different application scenarios, such as Internet of Vehicles and eMBB multiplexing, etc.), where similar technical effects can be achieved. Additionally, the adoption of a unified solution for various scenarios, including but not limited to scenarios and URLLC, contributes to the reduction of hardware complexity and costs.

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 aradio protocol architecture of a user plane 350 and a control plane 300. In FIG. 3, the radio protocol architecture for a first node (UE or gNB) and a second node (gNB or UE) 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 the link between the first node and the second node 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. 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. Although not described in FIG. 3, the first node may comprise several higher layers above the L2 layer 355, such as a network layer (e.g., IP layer) terminated at a P-GW of the network side and an application layer terminated at the other side of the connection (e.g., a peer UE, a server, etc.).

The first node(450) may comprise a controller/processor 490, a data source/buffer 480, a receiving processor 452, a transmitter/receiver 456 and a transmitting processor 455, wherein the transmitter/receiver 456 comprises an antenna 460.

In DL (Downlink), a higher-layer packet, such as higher-layer information carried by the first information block and the second information block in the present application (when the first information block comprises higher-layer information) is provided to the controller/processor 440. The controller/processor 440 implements the functionality of the L2 layer and the higher layer. In DL transmission, the controller/processor 440 provides header compression, encryption, packet segmentation and reordering and multiplexing between a logical channel and a transport channel, as well as radio resource allocation for the first node 450 based on varied priorities. The controller/processor 440 is also in charge of HARQ operation, retransmission of a lost packet, and a signaling to the first node 450, for instance, higher-layer information comprised in the first information block and the second information block in the present application are all generated in the controller/processor 440. The transmitting processor 415 provides various signal-processing functions for the L1 layer (that is, PHY), including coding, interleaving, scrambling, modulating, power control/allocation, precoding and generation of physical-layer control signaling, such as the generation of a physical-layer signal carrying the first information block and the second information block and the first signaling are completed at the transmitter 415. The generated modulation symbols are divided into parallel streams and each stream is mapped onto a corresponding multicarrier subcarrier and/or a multicarrier symbol, which is later mapped from the transmitting processor 415 to the antenna 420 via the transmitter 416 in the form of a radio frequency signal. At the receiving side, each receiver 456 receives an RF signal via a corresponding antenna 460, each receiver 456 recovers baseband information modulated to the RF carrier and provides the baseband information to the receiving processor 452. The receiving processor 452 provides various signal receiving functions for the L1 layer. The signal receiving processing function includes a reception of a physical-layer signal carrying the first information block and a physical-layer signal carrying the second information block as well as areception of afirst signaling. Multicarrier symbols in multicarrier symbol streams are demodulated based on varied modulation schemes (i.e., BPSCK, QPSK), and are then de-scrambled, decoded and de-interleaved to recover data or control signal transmitted by the second node 410 on a physical channel. And after that the data and control signal are provided to the controller/processor 490. The controller/processor 490 is in charge of the function of L2 layer and above layers, and the controller/processor 490 interprets higher-layer information comprised in the first information block and higher-layer information carried by the second information block in the present application. The controller/processor can be connected to a memory 480 that stores program code and data. The memory 480 may be called a computer readable medium.

In uplink (UL) transmission, similar to downlink transmission, higher-layer information is generated at the controller/processor 490 and then through the transmitting processor 455 to implement various signal transmission processing functions for the L1 layer (i.e., the physical layer). The first PUCCH in the present application is generated at the transmitting processor 455 and then mapped to the antenna 460 through the transmitter 456 by the transmitting processor 455 to be transmitted in the form of an RF signal. The receiver 416 receives a radio-frequency signal via its corresponding antenna 420, and each receiver 416 recovers baseband information modulated to a radio-frequency carrier, and supplies the baseband information to the receiving processor 412. The receiving processor 412 implements various signal reception and processing functions for the L1 layer (i.e., the physical layer), including receiving and processing the physical-layer signal of the first PUCCH in the present application, and then providing data and/or control signals to the controller/processor 440. The controller/processor 440 performs functions of L2 layer, including interpreting higher-layer information. The controller/processor can be connected to a buffer 430 that stores program code and data. The buffer 430 may be called a computer readable medium.
