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 for multi-carriers 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).

In the new air interface technology, multi-carrier (including carrier aggregation and dual connectivity, etc.) technology is an important component. In order to be able to adapt to various application scenarios and meet different requirements, 3GPP has evolved from Rel-15 version on multicarrier technology.

Disclosure of Invention

In a multi-carrier communication procedure, such as carrier aggregation (CA, carrier Aggregation), cross-carrier scheduling is supported (Cross Carrier Scheduling). In the existing standard supported network, for example, R17 and the previous release of 5G NR (New Radio), for a plurality of scheduled carriers, scheduling is only supported on a corresponding carrier or a corresponding PDCCH (Physical Downlink Control Channel ), but not supported by the same PDCCH on the same carrier.

The application discloses a solution to the problem of scheduling multiple carriers simultaneously with the same PDCCH in an NR multi-carrier system. It should be noted that, in the description of the present application, only PDCCH scheduling in multiple carriers is taken as a typical application scenario or example; the application is also applicable to other scenarios (such as other scenarios with higher requirements on control channel capacity, including but not limited to capacity enhancement systems, systems employing higher frequencies, coverage enhancement systems, unlicensed frequency domain communications, ioT (Internet of Things, internet of things), URLLC (Ultra Reliable Low Latency Communication, ultra-robust low latency communications) networks, internet of vehicles, etc.) that face similar problems, and similar technical effects can be achieved. Furthermore, the adoption of a unified solution for different scenarios, including but not limited to multi-carrier scenarios, also helps to reduce hardware complexity and cost. Embodiments of the present application and features of embodiments may be applied to a second node device and vice versa without conflict. In particular, the term (Terminology), noun, function, variable in the present application may be interpreted (if not specifically stated) with reference to the definitions in the 3GPP specification protocols TS36 series, TS38 series, TS37 series.

The application discloses a method used in a first node in wireless communication, which is characterized by comprising the following steps:

receiving a first information block, the first information block being used to determine a target set of cells, the target set of cells comprising a plurality of serving cells;

Example 3

Embodiment 3 shows a schematic diagram of an embodiment of a radio protocol architecture of a user plane and a control plane according to the 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 device (UE or gNB) and a second node device (gNB or UE) 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 link between the first node device and the second node device 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 device. 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 device between second node devices. 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 node devices. 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 device and the first node device. The radio protocol architecture of the user plane 350 includes layer 1 (L1 layer) and layer 2 (L2 layer), and the radio protocol architecture for the first node device and the second node device in the user plane 350 is substantially the same for the physical layer 351, the PDCP sublayer 354 in the L2 layer 355, the RLC sublayer 353 in the L2 layer 355, and the 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 data 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.
