Description

Technical Field

[0001] This application relates to transmission methods and apparatus in wireless communication systems, and more particularly to schemes and apparatus for capability reporting in wireless communication. Background Technology

[0002] The application scenarios of future wireless communication systems are becoming increasingly diversified, and different application scenarios place different performance requirements on the system. To meet the diverse performance needs of various application scenarios, research on New Radio (NR) (or 5G) was initiated at the 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) #72 plenary meeting. With the widespread application of 5G, new business models and application scenarios are constantly emerging, and the existing 5G standard cannot fully meet the new demands. Therefore, 3GPP is preparing to begin preliminary research on 6G.

[0003] With the diversification of application scenarios and the emergence of new business models, the demand for ubiquitous coverage is increasing day by day. Therefore, 6G needs to explore wireless transmission methods that can guarantee coverage. Summary of the Invention

[0004] Both 4G and 5G systems support carrier aggregation (CA), which allows different frequency domain resources to be used together, increasing overall bandwidth and thus transmission rate and throughput. However, in existing 4G and 5G systems, each component carrier (CC) corresponds to a cell, and it does not support two or more component carriers corresponding to the same cell. This approach in existing 4G and 5G systems greatly limits the spectrum flexibility in carrier aggregation, especially limiting the use of many fragmented spectrum resources. As spectrum resources (especially low-frequency spectrum resources) become increasingly valuable, 6G networks need to find a more flexible and efficient way to utilize spectrum resources. Having multiple carriers or spectrum distributed across multiple frequency bands corresponding to the same cell, thus supporting uplink and downlink transmissions distributed across multiple carriers, is considered a more efficient means for 6G networks to utilize spectrum resources. Furthermore, in existing 4G and 5G systems, considering the differences in hardware architecture among different user devices, each user device reports its capabilities to the base station, such as whether it supports carrier aggregation. According to the applicant's research, in 6G systems, it is insufficient for user devices to simply inform the base station which frequency bands the spectrum can correspond to the same cell. Without knowing the user device's further processing capabilities for transport blocks in a multi-carrier cell, the base station cannot adapt the scheduling strategy accordingly or adjust the protocol stack settings accordingly. Therefore, it cannot optimize the performance of multi-carrier cells and fully leverage their advantages.

[0005] This application discloses a solution to the problem of reporting TB transmission capacity in a single cell with multiple carriers. It should be noted that the description in this application uses multi-carrier single-cell (or single-cell multi-carrier) as a typical application scenario or example. This application is also applicable to 6G networks or other scenarios facing similar problems in the future (such as other scenarios that require the joint use of multiple carriers, or other scenarios that require the effective utilization of fragmented spectrum, such as 2G or 3G spectrum refarming, or other scenarios utilizing idle spectrum from non-cellular systems). For different application scenarios, such as eMBB, URLLC, full-duplex networks, IoT, sensor networks, integrated sensing networks, smart metasurfaces, and terahertz networks, V2X can also achieve similar technical effects. In addition, adopting a unified solution for different scenarios (including but not limited to eMBB, URLLC, full-duplex networks, IoT, sensor networks, integrated sensing networks, smart metasurfaces, terahertz networks, and V2X scenarios) or different application parameters can also help reduce hardware complexity and cost. Where there is no conflict, the embodiments and features in the embodiments used in the first node of this application can be applied to the embodiments used in the second node of this application, and vice versa.

[0221] Example 3

[0222] Example 3 illustrates a schematic diagram of a wireless protocol architecture for the user plane and control plane according to an embodiment of this application, as shown in the attached diagram. Figure 3 As shown. Figure 3 This is a schematic diagram illustrating an embodiment of a radio protocol architecture for the user plane 350 and the control plane 300. Figure 3The radio protocol architecture for the control plane 300 used by the first node (UE) and the second node (gNB) is illustrated using 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. Layer 1 will be referred to herein as PHY301. Layer 2 (L2 layer) 305 sits above PHY301 and is responsible for the link between the first and second nodes via PHY301. Layer 2 305 includes a MAC (Medium Access Control) sublayer 302, an RLC (Radio Link Control) sublayer 303, and a PDCP (Packet Data Convergence Protocol) sublayer 304, which terminate at the second node. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides security through encrypted data packets and supports cross-regional mobility between the second and first nodes. RLC sublayer 303 provides upper-layer packet segmentation and reassembly, retransmission of lost packets, and packet reordering to compensate for out-of-order reception due to HARQ. MAC sublayer 302 provides multiplexing between the logical and transport channels. MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) within a cell among the first nodes. MAC sublayer 302 is also responsible for HARQ operations. The RRC (Radio Resource Control) sublayer 306 in Layer 3 (L3) of the control plane 300 is responsible for acquiring radio resources (i.e., radio bearers) and configuring the lower layer using RRC signaling between the second and first nodes. The radio protocol architecture of user plane 350 includes Layer 1 (L1 layer) and Layer 2 (L2 layer). The radio protocol architecture for the first and second nodes in user plane 350 is largely the same as the corresponding layers and sublayers in control plane 300 for Physical Layer 351, PDCP sublayer 354 in L2 layer 355, RLC sublayer 353 in L2 layer 355, and MAC sublayer 352 in L2 layer 355. However, PDCP sublayer 354 also provides header compression for upper layer packets to reduce radio transmission overhead. L2 layer 355 in user plane 350 also includes SDAP (Service Data Adaptation Protocol) sublayer 356. SDAP sublayer 356 is responsible for mapping between QoS streams and Data Radio Bearers (DRBs) to support service diversity.Although not illustrated, the first node may have several upper layers above L2 layer 355, including a network layer (e.g., IP layer) terminating at the P-GW on the network side and an application layer terminating at the other end of the connection (e.g., remote UE, server, etc.).
