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 ubiquitous coverage is increasing day by day. Therefore, 6G needs to explore wireless transmission methods that can guarantee coverage. Summary of the Invention

[0004] 5G systems (including 5G-Advanced) support multiple random access preamble formats and multiple random access channel configuration indices, thus supporting sets of multiple independently configured random access opportunities. These sets of independently configured random access opportunities may lead to conflicts between them. In existing 5G systems, when conflicting random access opportunities occur (e.g., in Subband Non-Overlapping FullDuplex (SBFD) scenarios), the random access opportunity corresponding to a particular random access configuration or type is either discarded (deemed invalid) or the network configuration ensures that conflicts do not occur. These practices have a negligible impact on the random access performance of existing 5G networks. However, in 6G networks, the applicant's research found that due to scenarios with wide and seamless coverage (such as NTN (non-terrestrial network)) and terminal diversity (with and without timing precompensation), it may be necessary to simultaneously support random access designs with significant differences. For example, simultaneously supporting extremely long and short random access preamble sequences, or supporting random access configurations where conflicts of random access opportunities cannot be avoided. In such cases, the conflict resolution methods used in 5G may lead to the continuous dropping of random access opportunities corresponding to a particular random access configuration or type of random opportunity, or even the inability to initiate a random access procedure for that configuration or type of random opportunity, significantly reducing random access capacity and increasing the probability of collisions.

[0005] To address the issue of conflicting random access opportunities, this application discloses a solution. It should be noted that the description in this application uses large latency differences (such as NTN) as a typical application scenario or example; this application is also applicable to 6G networks or other scenarios facing similar problems in the future (e.g., other scenarios requiring ultra-long random access preamble sequences, or other scenarios with large coverage areas, such as scenarios with particularly large cell radii, rural coverage scenarios, or maritime coverage scenarios). 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. Furthermore, using 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 helps reduce hardware complexity and cost. Where there is no conflict, the embodiments and features described in the first node of this application can be applied to the embodiments described in the second node of this application, and vice versa.

[0215] As one embodiment, the validity of at least one of the plurality of candidate opportunities in a time-domain conflicting candidate opportunity depends on the relationship between the at least one time-domain conflicting candidate opportunity and the first resource pool, including: when the at least one time-domain conflicting candidate opportunity and the first resource pool have a first relationship, the validity of the at least one time-domain conflicting candidate opportunity depends on whether the first node has timing pre-compensation; when the at least one time-domain conflicting candidate opportunity and the first resource pool have a second relationship, the at least one time-domain conflicting candidate opportunity is valid. As a supplementary embodiment of the above embodiment, the first relationship and the second relationship are different. As a supplementary embodiment of the above embodiment, the first relationship is that the at least one time-domain conflicting candidate opportunity and the first resource pool have overlapping resources, and the second relationship is that the at least one time-domain conflicting candidate opportunity and the first resource pool do not have overlapping resources.

As an additional embodiment of the above embodiments, the possible relationship between the at least one of the plurality of candidate opportunities in the temporal conflicting candidate opportunity and the first resource pool also includes relationships other than the first relationship or the second relationship.

[0216] As one embodiment, the validity of at least one of the plurality of candidate opportunities in a time-domain conflicting candidate opportunity depends on the relationship between the at least one time-domain conflicting candidate opportunity and the first resource pool, including: when the at least one time-domain conflicting candidate opportunity and the first resource pool have a first relationship, the validity of the at least one time-domain conflicting candidate opportunity depends on whether the first node has timing pre-compensation; when the at least one time-domain conflicting candidate opportunity and the first resource pool have a second relationship, the at least one time-domain conflicting candidate opportunity is invalid.

As an additional embodiment of the above embodiments, the possible relationship between the at least one of the plurality of candidate opportunities in the temporal conflicting candidate opportunity and the first resource pool also includes relationships other than the first relationship or the second relationship.

[0217] As an example, a type of random access opportunity belonging to or overlapping with the first resource pool is determined to be valid. The network side can then provide basic guarantees for this type of random access opportunity, thereby enhancing the capacity of another type of random access while avoiding continuous dropping.

[0218] As an example, a type of random access opportunity that does not belong to the first resource pool or does not overlap with the first resource pool is determined to be valid. The network side then excludes some of these random access opportunities, thereby optimizing the reserved random access capacity for other types of random access opportunities.

[0219] As an example, in addition to determining the validity of access opportunities at any time based on the relationship with the resource pool, other factors (such as priority, preamble sequence format, pre-compensation capability, etc.) are also considered to further resolve the conflict problem while avoiding continuous dropping, thereby increasing the probability of successful random access.

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. The NG-RAN includes network node 203 and other network nodes 204. Network node 203 provides user and control plane protocol termination toward UE 201. Network node 203 can connect to other network nodes 204 via backhaul. Network node 203 may also be referred to as eNB, gNB, base station, ground station, satellite base station, aircraft base station, base transceiver station, radio base station, radio transceiver, transceiver function, Basic Services Set (BSS), Extended Services Set (ESS), TRP (Transmitter Receiver Node), or some other suitable term.

The MME / AMF / SMF211 is the control node that handles signaling between UE201 and 6GC / 5GC / EPC210. ​​Essentially, the MME / AMF / SMF211 provides bearer and connection management. All user IP (Internet Protocol) packets are transmitted through the S-GW / UPF212, which is itself connected to the P-GW / UPF213. The P-GW provides UE IP address allocation and other functions.

[0228] Example 3

[0229] 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. L1 layer will be referred to as PHY301 in this document. Layer 2 (L2 layer) 305 sits above PHY301 and is responsible for the link between the first and second nodes via PHY301. L2 layer 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.).

[0234] Example 4

[0235] 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.

[0236] 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.

[0237] 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.

[0238] 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 layer and above functions. The controller / processor 440 provides header compression, encryption, packet segmentation and reordering, multiplexing between logic 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 operation, retransmission of lost packets, and higher-layer signaling to the first node 450. The higher-layer information carried by the first and second information blocks in this application is generated in the controller / processor 440. The 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, such as physical layer signals carrying the first information block, physical layer signals carrying the second information block, and physical layer signals carrying the first command, which are completed in the 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 transmitted by the transmit processor 415 via the transmitter 416 to the antenna 420 as radio frequency (RF) signals. At the receiver, 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 the receive processor 452. The receive processor 452 implements various signal reception processing functions of the L1 layer. These functions include receiving the physical layer signal carrying the first information block, the physical layer signal carrying the second information block, and the physical layer signal carrying the first command; demodulating the multi-carrier symbols in the multi-carrier symbol stream based on various modulation schemes (e.g., Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK)); 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-level information, including the higher-level information carried in the first and second information blocks of this application. The controller / processor may be associated with a memory 480 that stores program code and data. The memory 480 may be referred to as a computer-readable medium.

[0239] In the transmission from the first node (450) to the second node (410), similar to the transmission from the second node (410) to the first node (450), higher-layer information (including the higher-layer information carried by the random access preamble in this application, if the random access preamble carries higher-layer information) is generated by the controller / processor 490 and then processed by the transmitter processor 455 for various signal transmission processing functions for the L1 layer (i.e., the physical layer). The transmitter processor 455 transmits the signal as a radio frequency signal via the transmitter 456 mapped to the antenna 460. The receiver 416 receives the radio frequency signal through its corresponding antenna 420. Each receiver 416 recovers the baseband information modulated onto the radio frequency carrier and provides the baseband information to the receiver processor 412. The receiver processor 412 implements various signal reception processing functions for the L1 layer (i.e., the physical layer) and then provides data and / or control signals to the controller / processor 440. Implementing L2 layer functions in the controller / processor 440 includes interpreting higher-layer information, including higher-layer information carried by the random access preamble in this application, if the random access preamble carries higher-layer information. The controller / processor may be associated with a memory 430 that stores program code and data. The memory 430 may be a computer-readable medium.
