Description

Technical Field

[0001] The present application relates to a method for setting random access information in a wireless communication system, especially related to self-optimization. Background Art

[0002] The application scenarios of future wireless communication systems are becoming more and more diversified, and different application scenarios put forward different performance requirements for the system. In order to meet the different performance requirements of various application scenarios, it was decided at the 72nd plenary session of 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) to conduct research on the new air interface technology (NR, New Radio) (or Fifth Generation, 5G). At the 75th plenary session of 3GPP RAN, the WI (Work Item) of NR was adopted, and the standardization work of NR was started.

[0003] In communication, whether it is LTE (Long Term Evolution) or 5G NR, it involves the accurate reception of reliable information, optimized energy efficiency ratio, determination of information validity, flexible resource allocation, scalable system architecture, efficient non-access stratum information processing, low service interruption and disconnection rates, support for low power consumption, which is of great significance for the normal communication between base stations and user equipment, for the reasonable scheduling of resources, and for the balance of system load. It can be said that it is the cornerstone of high throughput, meeting the communication needs of various services, improving spectrum utilization, and improving service quality. It is indispensable for eMBB (enhanced Mobile BroadBand), URLLC (Ultra Reliable Low Latency Communication), or eMTC (enhanced Machine Type Communication). At the same time, in IIoT (Industrial Internet of Things in the industrial field), in V2X (Vehicular to X), in device-to-device communication, in communication in unlicensed spectrum, in user communication quality monitoring, in network planning and optimization, in TN (Territerial Network), in dual connectivity systems, in wireless resource management and multi-antenna codebook selection, in signaling design, neighbor cell management, service management, and in beamforming, there are extensive requirements. The information sending methods are divided into broadcast and unicast, and both sending methods are essential for the 5G system because they are very helpful for meeting the above requirements.

[0004] With the continuous increase in the scenarios and complexity of the system, higher requirements are also put forward for reducing the interruption rate, reducing latency, enhancing reliability, enhancing system stability, business flexibility, and power saving. At the same time, when designing the system, the compatibility between different system versions also needs to be considered. Summary of the Invention

It should be particularly emphasized that the order of the boxes in the figure does not represent the temporal sequence of the steps represented.

[0066] In Embodiment 1, the terminal in the present application initiates a first random access procedure on a first cell in step 101; and sets a first random access report in a first UE variable after the first random access procedure is completed in step 102.

[0078] As an embodiment, the serving cell refers to the cell where the UE camps. Performing cell search includes the UE searching for a suitable cell of the selected PLMN (Public Land Mobile Network) or SNPN (Stand - alone Non - Public Network), selecting the suitable cell to provide available services, and monitoring the control channel of the suitable cell. This process is defined as camping on the cell; that is, a camped cell is the serving cell of this UE relative to this UE. Camping on a cell in the RRC idle state or RRC inactive state has the following benefits: enabling the UE to receive system messages from the PLMN or SNPN; when registered, if the UE wishes to establish an RRC connection or resume a suspended RRC connection, the UE can achieve this by performing initial access on the control channel of the camped cell; the network can page the UE; enabling the UE to receive ETWS (Earthquake and Tsunami Warning System) and CMAS (Commercial Mobile Alert System) notifications.

[0079] As an example, for a UE in RRC connected state without CA / DC (carrier aggregation / dual connectivity) configured, there is only one serving cell which includes the primary cell. For a UE in RRC connected state with CA / DC (carrier aggregation / dual connectivity) configured, the serving cell is used to indicate the cell set including the special cell (SpCell, Special Cell) and all secondary cells. The primary cell is an MCG (Master Cell Group) cell that operates on the primary frequency, and the UE performs the initial connection establishment process or initiates connection reestablishment on the primary cell.

[0341] Example 3

[0342] Embodiment 3 shows a schematic diagram of an embodiment of a radio protocol architecture for a user plane and a control plane according to the present application, as shown in the appendix Figure 3 as follows. Figure 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for the user plane 350 and the control plane 300, Figure 3Show the radio protocol architecture of the control plane 300 for the first node (UE, gNB) and the second node (gNB, UE), or between two UEs, with 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 as PHY 301 in this document. Layer 2 (L2 layer) 305 is above PHY 301 and is responsible for the link between the first node and the second node, and between two UEs through PHY 301. 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, and these sublayers 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 by encrypting data packets, and provides handover support for the first node between the second nodes. 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 disordered reception due to HARQ. The MAC sublayer 302 provides multiplexing between logical and transport channels. The MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) in a cell between the first nodes. The MAC sublayer 302 is also responsible for HARQ operations. The RRC (Radio Resource Control) sublayer 306 in Layer 3 (L3 layer) of 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 and the first node. The PC5-S (PC5 Signaling Protocol) sublayer 307 is responsible for handling the signaling protocol of the PC5 interface. The radio protocol architecture of the user plane 350 includes Layer 1 (L1 layer) and Layer 2 (L2 layer). For the radio protocol architecture of the first node and the second node in the user plane 350, 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 are generally the same 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.The L2 layer 355 in the user plane 350 further includes an SDAP (Service Data Adaptation Protocol) sublayer 356. The SDAP sublayer 356 is responsible for the mapping between QoS flows and data radio bearers (DRBs) to support service diversity. The SRB can be regarded as a service or interface provided by the PDCP layer to higher layers, such as the RRC layer. In the NR system, the SRB includes SRB1, SRB2, and SRB3, which are respectively used to transmit different types of control signaling. The SRB is a bearer between the UE and the access network and is used to transmit control signaling including RRC signaling between the UE and the access network. SRB1 is of particular significance to the UE. After each UE establishes an RRC connection, there will be an SRB1 for transmitting RRC signaling. Most signaling is transmitted through SRB1. If SRB1 is interrupted or unavailable, the UE must perform RRC reconstruction. SRB2 is generally only used to transmit NAS signaling or signaling related to security. The UE may not be configured with SRB3. Except for emergency services, the UE must establish an RRC connection with the network to perform subsequent communication. Although not shown, the first node may have several upper layers above the L2 layer 355. In addition, it also includes a network layer (e.g., IP layer) terminated at the P-GW on the network side and an application layer terminated at the other end of the connection (e.g., a remote UE, a server, etc.).

[0353] Example 4

[0354] Embodiment 4 shows a schematic diagram of a first communication device and a second communication device according to an embodiment of the present application, as shown in the appendix Figure 4 as shown. Figure 4 is a block diagram of a first communication device 450 and a second communication device 410 that communicate with each other in an access network.

[0355] The first communication device 450 includes a controller / processor 459, a memory 460, a data source 467, a transmitting processor 468, a receiving processor 456, and optionally a multi-antenna transmitting processor 457, a multi-antenna receiving processor 458, a transmitter / receiver 454, and an antenna 452.

[0356] The second communication device 410 includes a controller / processor 475, a memory 476, a receiving processor 470, a transmitting processor 416, and optionally a multi-antenna receiving processor 472, a multi-antenna transmitting processor 471, a transmitter / receiver 418, and an antenna 420.

[0357] In the transmission from the second communication device 410 to the first communication device 450, at the second communication device 410, upper layer data packets from the core network are provided to the controller / processor 475. The controller / processor 475 implements the functionality of the L2 (Layer-2) layer. In the transmission from the second communication device 410 to the first communication device 450, the controller / processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation for the first communication device 450 based on various priority metrics. The controller / processor 475 is also responsible for retransmission of lost packets and signaling to the first communication device 450. The transmit processor 416 and the multi-antenna transmit processor 471 implement various signal processing functions for the L1 layer (i.e., the physical layer). The transmit processor 416 implements encoding and interleaving to facilitate forward error correction (FEC) at the second communication device 410, and mapping of signal constellations based on various modulation schemes (e.g., binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), M-phase shift keying (M-PSK), M-quadrature amplitude modulation (M-QAM)). The multi-antenna transmit processor 471 performs digital spatial precoding on the encoded and modulated symbols, including codebook-based precoding and non-codebook-based precoding, and beamforming processing, to generate one or more spatial streams. The transmit processor 416 then maps each spatial stream to subcarriers, multiplexes with reference signals (e.g., pilots) in the time domain and / or frequency domain, and then uses the inverse fast Fourier transform (IFFT) to generate a physical channel carrying a time-domain multi-carrier symbol stream. Subsequently, the multi-antenna transmit processor 471 performs transmit analog precoding / beamforming operations on the time-domain multi-carrier symbol stream. Each transmitter 418 converts the baseband multi-carrier symbol stream provided by the multi-antenna transmit processor 471 into a radio frequency stream and then provides it to a different antenna 420.

[0358] In the transmission from the second communication device 410 to the first communication device 450, at the first communication device 450, each receiver 454 receives signals via its respective antenna 452. Each receiver 454 recovers the information modulated onto the radio frequency carrier and converts the radio frequency stream into a baseband multi-carrier symbol stream for providing to the receive processor 456. The receive processor 456 and the multi-antenna receive processor 458 perform various signal processing functions of the L1 layer. The multi-antenna receive processor 458 performs receive analog precoding / beamforming operations on the baseband multi-carrier symbol stream from the receivers 454. The receive processor 456 uses the fast Fourier transform (FFT) to convert the baseband multi-carrier symbol stream after the receive analog precoding / beamforming operations from the time domain to the frequency domain. In the frequency domain, the physical layer data signal and the reference signal are demultiplexed by the receive processor 456, where the reference signal will be used for channel estimation, and the data signal recovers any spatial streams destined for the first communication device 450 after multi-antenna detection in the multi-antenna receive processor 458. The symbols on each spatial stream are demodulated and recovered in the receive processor 456, and soft decisions are generated. Subsequently, the receive processor 456 decodes and deinterleaves the soft decisions to recover the upper layer data and control signals transmitted by the second communication device 410 on the physical channel. Subsequently, the upper layer data and control signals are provided to the controller / processor 459. The controller / processor 459 performs the functions of the L2 layer. The controller / processor 459 may be associated with a memory 460 that stores program code and data. The memory 460 may be referred to as a computer-readable medium. In the transmission from the second communication device 410 to the second communication device 450, the controller / processor 459 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, control signal processing to recover upper layer data packets from the core network. Subsequently, the upper layer data packets are provided to all protocol layers above the L2 layer. Various control signals may also be provided to the L3 for L3 processing.

[0359] In the transmission from the first communication device 450 to the second communication device 410, at the first communication device 450, a data source 467 is used to provide upper layer data packets to a controller / processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to the transmit function described at the second communication device 410 in the transmission from the second communication device 410 to the first communication device 450, the controller / processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on radio resource allocation, and implements L2 layer functions for the user plane and the control plane. The controller / processor 459 is also responsible for retransmission of lost packets and signaling to the second communication device 410. A transmit processor 468 performs modulation mapping and channel coding processing, and a multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming processing. Subsequently, the transmit processor 468 modulates the generated spatial streams into multi-carrier / single-carrier symbol streams, and after an analog precoding / beamforming operation in the multi-antenna transmit processor 457, provides them to different antennas 452 via a transmitter 454. Each transmitter 454 first converts the baseband symbol stream provided by the multi-antenna transmit processor 457 into a radio frequency symbol stream and then provides it to the antenna 452.

[0360] In the transmission from the first communication device 450 to the second communication device 410, the functions at the second communication device 410 are similar to the receive functions described at the first communication device 450 in the transmission from the second communication device 410 to the first communication device 450. Each receiver 418 receives radio frequency signals through its corresponding antenna 420, converts the received radio frequency signals into baseband signals, and provides the baseband signals to a multi-antenna receive processor 472 and a receive processor 470. The receive processor 470 and the multi-antenna receive processor 472 jointly implement the L1 layer functions. A controller / processor 475 implements the L2 layer functions. The controller / processor 475 may be associated with a memory 476 that stores program code and data. The memory 476 may be referred to as a computer-readable medium. In the transmission from the first communication device 450 to the second communication device 410, the controller / processor 475 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover upper layer data packets from the UE 450. The upper layer data packets from the controller / processor 475 may be provided to the core network.

[0439] As an example, the first node U01 sets the first report in the first message as the first random access report in the first UE variable; and sends the first message.

[0440] As a sub - example of this example, the name of the first report in the first message is the same as the first random access report.

[0441] As a sub - example of this example, the name of the first report in the first message is RA - Report.

[0442] As a sub - example of this example, the first report in the first message includes all the contents of the first random access report.

[0443] As a sub - example of this example, the first report in the first message includes information related to random access.

[0444] As an example, setting the first report in the first message as the first random access report in the first UE variable includes: setting the first report of the first message as the first random access report in the first UE variable.

[0445] As an example, setting the first report in the first message as the first random access report in the first UE variable includes: setting the content of the first report of the first message as the first random access report in the first UE variable.

[0446] As an example, setting the first report in the first message as the first random access report in the first UE variable includes: copying the first random access report in the first UE variable into the first report in the first message.

[0447] As an example, the first report in the first message is RA - report.

[0448] As an example, the first node U01 sets the first report list in the first message as the first report list in the first UE variable.

[0449] As an embodiment, the first report in the first message is one of the reports in the first report list in the first message.

[0450] As a sub - embodiment of this embodiment, the one report in the first report list is the first random access report.

[0451] As an embodiment, the first random access report in the first UE variable is one of the reports in the first report list in the first UE variable.

[0452] As an embodiment, the first report in the first message has the same data structure as the first random access report in the first UE variable.

[0453] As an embodiment, the first message includes the time when the first report is generated.

[0454] As an embodiment, the first message includes the time since the first random access report was set in the first UE variable.

[0455] As a quantity, the first message helps the network obtain the content recorded in the first UE variable, which is conducive to further optimizing the random access process.

[0456] As an embodiment, the first UE variable includes multiple random access reports, and the first report is one of the multiple random access reports in the first UE variable.

[0457] As an embodiment, the first UE variable includes multiple random access reports, and the first report is any one of the multiple random access reports in the first UE variable.

[0458] As an embodiment, if the network determines that the report in the first UE variable is not of interest to the network, or there is resource tension or network overload, or the network has received enough reports related to random access, then the network may not send the first request, which helps save the power of the UE and network resources.

[0459] As an embodiment, the first message can also be sent actively.

[0460] As an embodiment, step S5101 is before step S5102.

[0461] As an embodiment, step S5102 is before step S5103.

[0462] As an embodiment, step S5103 is before step S5104.

[0463] As an example, step S5104 is before step S5105.

[0464] As an example, step S5106 is before step S5106.

[0465] As an example, step S5201 is before step S5202.

[0466] As an example, step S5202 is before step S5203.

[0467] As an example, step S5203 is before step S5204.

[0468] As an example, after the network obtains the content recorded by the first UE variable through the first message, it is beneficial to optimize random access. For example, if the first UE variable records a random access conflict or failure in the first cell, more resources can be allocated to the first cell accordingly; if the first UE variable records the number of random access attempts in the first cell, when the number of random access attempts is large, the random access resources for the first cell can be increased to shorten the random access delay; the network can also use the information recorded by the first UE variable to count the number of random accesses on the first cell within a period of time, and allocate matching resources as much as possible, that is, shorten the random access delay and avoid resource waste.

[0469] Example 6

[0470] Embodiment 6 exemplifies a schematic diagram of a first cell and a second cell according to an embodiment of the present application, as shown in the appendix Figure 6 as shown.

[0471] The method proposed in the present application does not limit the Figure 6 shape and size of the first cell and / or the second cell in the appendix, nor does it limit the overlapping relationship between the first cell and the second cell.

[0472] As an example, the second cell is the PCell of the first node and the SpCell of the MCG of the first node.

[0473] As an example, the RRC connection between the first node and the network terminates at the first node and the second cell.

[0477] As an embodiment, the SCG to which the first cell belongs is added by signaling sent by the second cell.

[0478] As an embodiment, the first cell is switched from signaling sent by the second cell.

[0479] As an embodiment, the first cell and the second cell respectively correspond to the first cell's SCG and MCG.

[0480] As an embodiment, the first node is in the RRC connected state.

[0481] As an embodiment, when entering the RRC idle state, the first node needs to release the SCG.

[0482] As an embodiment, the first cell and the second cell are out of sync.

[0483] As an embodiment, the first node makes the uplink transmission of the first node synchronized with the first cell through the first random access procedure.

[0484] As an embodiment, when the radio access technology of the first cell is the first radio access technology, the maximum value of the number of fields indicating the number of transmitted Preambles in the first random access report is greater than when the radio access technology of the first cell is the second radio access technology, which is beneficial to maintaining the optimization of the reasonable complexity of random access to different external radio access technologies.

[0485] As an embodiment, for cells with different radio access technologies, the random access procedure includes transmitting a Preamble.

[0486] As an embodiment, a single random access procedure can transmit multiple Preambles, for example, through configuration, and in the last Preamble, the single random access procedure is successfully completed.

[0487] As an embodiment, the content of the first random access report is sent to the second cell through the first cell.

[0488] As an embodiment, when the first cell changes the PCell, the content of the first random access report is sent to the new PCell through the first cell.

[0489] As an embodiment, the content of the first random access report is sent to the second cell through SRB1, or sent to the first cell through SRB3 and then forwarded by the first cell to the second cell.

[0490] Example 7

[0491] Embodiment 7 exemplifies a schematic diagram of a random access procedure according to an embodiment of the present application, as shown in the appended Figure 7 drawing. The first node in the appended Figure 7 drawing is the terminal of the present application.

[0492] The appended Figure 7 drawing shows a 4-step random access procedure. The method proposed in the present application is not limited to a 4-step random access procedure. For a 4-step random access procedure, the method proposed in the present application can be optimized very specifically.

[0493] As an embodiment, for the first node, in the 4-step random access procedure, the first step is to send a Preamble, the second step is to receive a random access response, the third step is to send a first uplink transmission, and the fourth step is conflict resolution.

[0494] As an embodiment, if the first node does not receive a random access response in the second step, it initiates a random access attempt again, including re-sending the Preamble.

[0495] As an embodiment, if the first node does not complete conflict resolution in the fourth step, it initiates a random access attempt again, including re-sending the Preamble.

[0496] As an embodiment, the random access response indicates the resources for the first uplink transmission.

[0497] As an embodiment, the first uplink transmission includes sending an RRC message.

[0498] As a sub-embodiment of this embodiment, the sent RRC message uses SRB0.

[0499] As a sub-embodiment of this embodiment, the sent RRC message is used for RRC connection establishment or recovery or reconstruction.

[0500] As an embodiment, the first uplink transmission includes sending a MAC CE.

[0501] As an embodiment, in the random access procedure for certain random access purposes, such as uplink synchronization, receiving a random access response completes the random access procedure.

[0502] As an example, during the random access procedure for certain random access purposes, it is possible to determine the completion of the random access upon receiving the information on the expected PDCCH.

[0503] As an example, the first random access procedure is a 4-step random access procedure.

[0504] As an example, setting the first random access report in the first UE variable includes setting the conditions for the completion of the first random access procedure.

[0505] As an example, setting the first random access report in the first UE variable includes setting whether the first random access procedure requires a PDCCH after receiving the preamble.

[0506] As an example, setting the first random access report in the first UE variable includes setting whether the first random access procedure requires receiving a random access response.

[0507] As an example, setting the first random access report in the first UE variable includes setting whether the first random access procedure requires contention resolution.

[0508] As an example, the above method is beneficial for more clearly optimizing different types of random access procedures and different steps in the random access procedure, with greater pertinence.

[0509] As an example, the first uplink transmission is or includes msg3.

[0510] As an example, setting the first random access report in the first UE variable includes setting the logical channel used by msg3 in the first random access procedure.

[0511] As an example, setting the first random access report in the first UE variable includes setting the size of msg3 in the first random access procedure.

[0512] As an example, setting the first random access report in the first UE variable includes setting whether msg3 in the first random access procedure is repeated and / or the number of repetitions.

[0513] As an example, the advantage of the above method is that the network can more clearly understand the configuration and transmission of msg3 during the random access procedure on the first cell, and is beneficial for better optimizing msg3.

For example, ra-ReportList is a field, and RA-ReportList is the corresponding information element. An information element can further include fields and the information elements corresponding to these fields; some fields in the appendix Figure 8 do not show the corresponding information elements, and their corresponding values or information elements will be described below.

[0607] As an example, when the radio access technology of the first cell is EUTRA, only setting information related to the former of the RRC-initiated random access procedure and the MAC-initiated random access procedure in the first random access report means not setting or recording information related to the former of the MAC-initiated random access procedure in the first random access report when the radio access technology of the first cell is EUTRA.
