Description

Method and apparatus in a node for wireless communication

Technical Field

The present application relates to a transmission method and apparatus in a wireless communication system, and more particularly, to a transmission scheme and apparatus of a control channel in wireless communication.

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 different performance requirements of various application scenarios, research on a New air interface technology (NR, new Radio) (or 5G) is decided on the 3GPP (3 rd Generation Partner Project, third generation partnership project) RAN (Radio Access Network ) #72 full-time, and standardization Work on NR is started on the 3GPP RAN #75 full-time WI (Work Item) that passes the New air interface technology (NR, new Radio).

Among the new air interface technologies, multi-antenna (such as multiple input multiple output (MIMO, multiple Input Multiple Output), multiple transmit receive node (TRP, transmission Reception Point) and multi-panel (Pannel)) technologies are important components. To be able to accommodate more diverse application scenarios and meet higher demands, a further enhanced WI over 3gpp ran #86 full-meeting with MIMO under NR is used to support multi-antenna communication that is more robust and spectrally efficient and for more application scenarios.

Disclosure of Invention

In a multi-antenna system, such as multi-transmit-receive node (TRP, transmission Reception Point) communications, the same channel or signal may be transmitted by multiple transmit-receive nodes to enhance the robustness of the transmission. Multiple transmit receive node transmissions of data channels are supported in release 16 (Rel-16), and 3GPP plans to introduce multiple transmit receive node transmissions of control channels in release 17 (Rel-17).

A solution is disclosed for the transmission problem of control channels in a multi-antenna system. It should be noted that, in the description of the present application, only the multi-antenna system, particularly the multi-transmitting-receiving-node transmission system is taken as a typical application scenario or example; the application is also applicable to other scenes facing similar problems (such as scenes with higher requirements on robustness or coverage of a control channel, or scenes requiring PDCCH association outside of multi-transmission receiving node transmission, including but not limited to coverage enhancement systems, ioT (Internet of Things, internet of things), URLLC (Ultra Reliable Low Latency Communication, ultra-robust low-latency communication) networks, internet of vehicles, and the like), and similar technical effects can be achieved. Furthermore, the adoption of a unified solution for different scenarios, including but not limited to the scenario of a multi-antenna system, also helps to reduce hardware complexity and cost.

The generated modulation symbols are divided into parallel streams and each stream is mapped to a respective multicarrier subcarrier and/or multicarrier symbol and then transmitted as a radio frequency signal by transmit processor 415 via transmitter 416 to antenna 420. At the receiving end, each receiver 456 receives a radio frequency signal through its respective antenna 460, each receiver 456 recovers baseband information modulated onto a radio frequency carrier, and provides the baseband information to the receive processor 452. The reception processor 452 implements various signal reception processing functions of the L1 layer. The signal reception processing functions include reception of physical layer signals of the first, second, and fourth information blocks in the present application and monitoring of M1 control channel alternatives in the present application, demodulation based on various modulation schemes (e.g., binary Phase Shift Keying (BPSK), quadrature Phase Shift Keying (QPSK)) by multicarrier symbols in a multicarrier symbol stream, followed by descrambling, decoding, and de-interleaving to recover data or control transmitted by the second node apparatus 410 over the physical channels, followed by providing the data and control signals to the controller/processor 490. The controller/processor 490 is responsible for the L2 layer and above, and the controller/processor 490 interprets the first, second and fourth information blocks in this application.
