Description

Technical Field

[0001] This application relates to transmission methods and apparatus in wireless communication systems, and more particularly to schemes and apparatus for random access 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 more flexible and effective use of spectrum resources is increasing day by day. Therefore, 6G needs to explore new ways of using spectrum resources. 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 flexible and efficient way to utilize spectrum resources. Having multiple carriers or spectrum distributed across multiple 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, existing 4G and 5G systems both employ OFDM (Orthogonal Frequency Division Multiplexing) based waveforms, defining a resource grid structure based on OFDM subcarriers or resource blocks for channel bandwidth allocation and resource allocation. However, the resource grids in existing 4G and 5G networks are configured independently for each component carrier. According to the applicant's research, this method of independently configuring the resource grid in existing 4G and 5G networks significantly reduces spectrum utilization, especially for fragmented spectrum in multi-carrier single-cell environments.

[0005] To address the issue of flexibly and effectively utilizing spectrum resources, this application discloses a solution. 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.

The 6GS / 5GS / EPS can interconnect with other access networks, but these entities / interfaces are not shown for simplicity. As shown in the figure, the 6GS / 5GS / EPS provides packet-switched services; however, those skilled in the art will readily understand that the various concepts presented throughout this application can be extended to networks providing circuit-switched services or other cellular networks.

[0224] Example 3

[0225] Example 3 illustrates a schematic diagram of an embodiment of a wireless protocol architecture for a user plane and a control plane according to 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.).

[0230] Example 4

[0231] Example 4 illustrates a schematic diagram of a first node and a second node according to an embodiment of this application, as shown in the attached diagram. Figure 4 As shown.

[0232] The first node (450) may include a controller / processor 490, a memory 480, a receiver processor 452, a transmitter / receiver 456 and a transmitter processor 455, the transmitter / receiver 456 including an antenna 460.

[0233] The second node (410) may include a controller / processor 440, a memory 430, a receiver processor 412, a transmitter / receiver 416 and a transmitter processor 415, the transmitter / receiver 416 including an antenna 420.

[0234] In the transmission from the second node (410) to the first node (450), upper-layer packets are provided to the controller / processor 440. The controller / processor 440 implements L2 and higher-layer functions. The controller / processor 440 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to the first node 450 based on various priority metrics. The controller / processor 440 is also responsible for HARQ operations, retransmission of lost packets, and higher-layer signaling to the first node 450. The higher-layer information carried in the first, second, and third information blocks of this application, as well as the higher-layer information carried in the scheduling information block (if the scheduling information block carries higher-layer information), is generated in the controller / processor 440. Transmit processor 415 implements various signal processing functions for the L1 layer (i.e., the physical layer), including encoding, interleaving, scrambling, modulation, power control / allocation, precoding, and physical layer control signaling generation. For example, physical layer signals carrying a first information block, a second information block, a third information block, and a scheduling information block are generated in transmit processor 415. The generated modulation symbols are divided into parallel streams, and each stream is mapped to a corresponding multi-carrier subcarrier and / or multi-carrier symbol. These are then mapped by transmit processor 415 to antenna 420 via transmitter 416 and transmitted as radio frequency (RF) signals. At the receiving end, each receiver 456 receives the RF signal through its corresponding antenna 460. Each receiver 456 recovers the baseband information modulated onto the RF carrier and provides the baseband information to receiver processor 452. Receiver processor 452 implements various L1 layer signal reception processing functions. The signal reception and processing function includes receiving the physical layer signals carrying the first information block, the second information block, the third information block, and the scheduling information block in this application; demodulating the signals based on various modulation schemes (e.g., Binary Phase Shift Keying (BPSK) and Quadrature Phase Shift Keying (QPSK)) using multi-carrier symbols in the multi-carrier symbol stream; subsequently descrambling, decoding, and deinterleaving to recover the data or control transmitted by the second node 410 on the physical channel; and then providing the data and control signals to the controller / processor 490. The controller / processor 490 is responsible for the L2 layer and above, and interprets higher-layer information. This includes interpreting the higher-layer information carried by the first, second, and third information blocks in this application, as well as the higher-layer information carried by the scheduling information block (if the scheduling information block includes higher-layer information).

[0285] Example 6

[0286] Example 6 illustrates a schematic diagram of the relationship between a first carrier and a second carrier according to an embodiment of this application, as shown in the attached diagram. Figure 6 As shown. In the appendix Figure 6 In cases A, B, and C, the horizontal axis represents frequency, the arc-shaped area filled with diagonal lines represents the first carrier, and the arc-shaped area filled with crosshairs represents the second carrier. In cases A and B, the first and second carriers share the same reference frequency. In case A, the first and second carriers correspond to two resource grids respectively. In case B, the first and second carriers share the same resource grid. In case C, the first and second carriers each have their own reference frequencies.

[0287] In Embodiment 6, the first carrier and the second carrier are two carriers among the plurality of carriers in this application. Whether the resource grids on the first carrier and the second carrier for a subcarrier interval share the same reference frequency depends on the relative frequency domain position relationship between the first carrier and the second carrier.

[0288] As an example, determining whether to share the same frequency reference point based on the relative frequency domain positions between carriers reduces the complexity of RF design.

[0289] As one embodiment, the first carrier and the second carrier are two different carriers among the plurality of carriers.

[0290] As an example, the first carrier and the second carrier belong to the same frequency range.

[0292] As an example, the channel bandwidth of the first carrier and the second carrier is the same.

[0293] As an example, the channel bandwidths of the first carrier and the second carrier may be different.

[0294] As an example, the channel bandwidth or transmission bandwidth of the first carrier and the second carrier are not greater than a predefined threshold or a frequency range-related threshold.

[0295] As an example, the carrier bandwidth of both the first carrier and the second carrier is not greater than a predefined threshold related to the frequency range.

[0296] As an example, the spectral bandwidth (including the guard band) occupied by the first carrier and the spectral bandwidth (including the guard band) occupied by the second carrier are both not greater than a predefined threshold or a frequency range-related threshold.

[0297] As an example, the channel bandwidth or transmission bandwidth of the first carrier and the second carrier are not greater than a threshold related to the user equipment capability.

[0298] As an example, the carrier bandwidth of both the first carrier and the second carrier is not greater than a threshold related to the user equipment capability.

[0299] As an example, the spectrum resources (including guard band) occupied by the first carrier and the frequency domain resources (including guard band) occupied by the second carrier are both no greater than a threshold related to the user equipment capabilities.

[0300] As an example, limiting the bandwidth of the first carrier and the second carrier limits the total number of points in the FFT operation, which helps to reduce complexity.

[0301] As an example, both the first carrier and the second carrier are FDD (Frequency-division Duplexing) carriers.

[0302] As an example, both the first carrier and the second carrier are TDD (Time-division Duplexing) carriers.

[0303] As an example, the frequency band to which the first carrier belongs and the frequency band to which the second carrier belongs are both FDD bands.

[0304] As an example, the frequency band to which the first carrier belongs and the frequency band to which the second carrier belongs are both TDD bands.
