Description

Technical Field

[0001] The present application relates to a transmission method and apparatus in a wireless communication system, and to coordinating time domain resources for two C-RNTIs of a node. Background Art

[0002] In the future, the application scenarios of wireless communication systems will become more and more diversified, and different application scenarios will put forward different performance requirements for the system. In order to meet the different performance requirements of various application scenarios, the 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) #72 plenary meeting decided to study the new radio (NR) (or Fifth Generation, 5G) technology, and the NR WI (Work Item) was passed at the 3GPP RAN #75 plenary meeting, and the standardization work on NR began.

[0003] In communication, both LTE (Long Term Evolution) and 5G NR involve accurate reception of reliable information, optimized energy efficiency, determination of information validity, flexible resource allocation, scalable system structure, efficient non-access layer information processing, low service interruption and drop rate, and support for low power consumption. This is of great significance to the normal communication between base stations and user equipment, the reasonable scheduling of resources, and the balancing of system loads. It can be said to be the cornerstone of high throughput, meeting the communication needs of various services, improving spectrum utilization, and improving service quality. It is indispensable for eMBB (ehanced Mobile BroadBand), URLLC (Ultra Reliable Low Latency Communication) and eMTC (enhanced Machine Type Communication). At the same time, in IIoT (Industrial Internet of Things, Industrial Internet of Things, V2X (Vehicular to X, vehicle-mounted communication), device-to-device communication, unlicensed spectrum communication, user communication quality monitoring, network planning optimization, NTN (Non Territerial Network, non-terrestrial network communication), TN (Territerial Network, terrestrial network communication), dual connectivity (Dual connectivity) system, wireless resource management and multi-antenna codebook selection, signaling design, neighbor management, business management, beamforming, there are extensive needs, information transmission methods are divided into broadcast and unicast, both transmission methods are essential for 5G systems, because they are very helpful to meet the above requirements. The UE can be connected to the network directly or through a relay.

[0004] As the scenarios and complexity of the system continue to increase, higher requirements are placed on reducing interruption rates, reducing latency, enhancing reliability, enhancing system stability, business flexibility, and power saving. At the same time, compatibility between different versions of different systems also needs to be considered during system design. Summary of the invention

[0005] The researchers found that when the first node has two identities, how to assist the network in coordinating time domain resources for different identities is a problem that needs to be solved. The researchers further found that when the two identities of the first node are relatively independent, that is, when the network may think that the two identities correspond to two UEs (user equipment), it is necessary to instruct the network on how to schedule time domain resources for different identities through uplink UE auxiliary information based on the first node. This can reduce the complexity of the network and improve efficiency, especially avoiding conflicts or resource competition that may occur when the network schedules the two identities of the first node separately. The researchers further found that C-RNTI is a very special identity in the field. It is an identity that every node that accesses the network has. Since the 3G network era, a node has only one C-RNTI (Cell Radio Network Temporary Identity). In a cell, C-RNTI uniquely identifies a UE. The network's scheduling for a UE is all for the C-RNTI of this UE. It can be said that unicast communication in the RRC connection state cannot be separated from C-RNTI. In future communications, a node is assigned two C-RNTIs, which has many benefits, such as greater security and adaptability to richer and more complex services. The researchers also found that when the first node has two SIM cards, especially when the SIM cards belong to the same operator and / or are connected to the same access network and the same cell, the network can assume that the two SIMs correspond to two UEs respectively, so the first node will be assigned two C-RNTIs. In such a scenario, if the two C-RNTIs are treated as independent UEs, that is, the C-RNTI is separated from the time domain resources, which is inefficient and prone to conflicts, affecting the performance of communication.

[0006] In view of the above-mentioned problems, this application provides a solution.

[0055] Implementation

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

[0059] In embodiment 1, the first node in the present application sends first UE auxiliary information in step 101.

[0060] Among them, the first UE auxiliary information indicates that the first time domain resource set and the second time domain resource set are scheduled for the first identity and the second identity of the first node respectively; the first identity and the second identity are both C-RNTI; the first time domain resource set and the second time domain resource set depend on the wireless frame configuration.

[0061] As an embodiment, the first node is a UE (User Equipment).

[0062] As an embodiment, the first node is in an RRC connected state.

[0063] As an embodiment, when the network does not know that the first identity and the second identity are both for the first node, it may schedule the first identity and the second identity on the same time domain resource at the same time. When the first node is limited by hardware capabilities, it cannot send and receive according to the scheduling for the first identity and the second identity at the same time; for example, when the first identity for the first node schedules downlink on a time domain resource but the second identity for the first node schedules uplink on the same time domain resource, the first node cannot handle it either; and the present application proposes using the first UE auxiliary information to indicate the first time domain resource set and the second time domain resource set according to the first identity and the second identity, which can effectively assist the network in avoiding similar problems.

[0176] As an embodiment, the first time domain resource set belongs to the TDD spectrum.

[0177] As an embodiment, the second time domain resource set belongs to the TDD spectrum.

[0178] As an embodiment, the first time domain resource set includes at least one TDD time slot.

[0183] As an embodiment, the time-frequency resources included in the second time-frequency resource set are TDD subframes.

[0184] As an embodiment, the benefits of the above method include: unlike FDD (frequency division duplex), the TDD system transmits uplink or downlink at different times. Normally, if uplink and downlink are transmitted at the same time, the uplink will cause serious interference to the downlink reception, that is, if the network schedules uplink and downlink respectively for the first identity and the second identity, it will cause interference between the two. Due to hardware limitations, the first node cannot send and receive at the same time. The above method is particularly useful for TDD and can effectively avoid conflicts and interference problems; at the same time, when the first node has some other communication needs, such as transmitting different services for the first identity and the second identity respectively, and communicating with other wireless networks such as WIFI, resulting in internal interference or hardware resource occupation and other problems, which are difficult for the network to predict. The coordination of time domain resources by the first node is conducive to ensuring normal communication and improving communication performance.

[0185] As an embodiment, the sentence that the first UE auxiliary information indicates that the first time domain resource set and the second time domain resource set are scheduled for the first identity and the second identity of the first node respectively means: the first UE auxiliary information indicates that the first time domain resource set and the second time domain resource set are only allowed to be scheduled as uplink for the first identity and the second identity of the first node respectively.

[0188] As an embodiment, the sentence that the first UE auxiliary information indicates that the first time domain resource set and the second time domain resource set are scheduled for the first identity and the second identity of the first node respectively means: the first UE auxiliary information indicates that the first time domain resource set and the second time domain resource set are only allowed to be scheduled as downlink for the first identity and the second identity of the first node respectively.

[0189] As a sub-embodiment of this embodiment, only the SFI (slot format indication) field in the scheduled signaling is allowed to indicate downlink.

[0190] As an embodiment, the benefits of the above method include: limiting the first time domain resource set and the second time domain resource set to only allow downlink scheduling, which is conducive to controlling the uplink and will not cause interference to the downlink; at the same time, uplink transmission resources can also be released, especially when the first node has only one transmitter and one or more receivers, hardware conflicts can be avoided.

[0191] As an embodiment, the first UE assistance information indicates that the first time domain resource set is for a first frequency set and the second time domain resource set is for a second frequency set.

[0198] As a sub-embodiment of this embodiment, the frequency combination is one of the supported frequency combinations indicated by the capability information sent by the first node to the network.

[0199] As an embodiment, the advantage of the above method is that it can more accurately reduce the restrictions on network scheduling and improve communication performance.

[0212] As an embodiment, the advantage of the above method is that associating the subframes within the same frame rather than arbitrary time domain resources, especially a TDD frame, with the scheduling of the first identity or the second identity of the first node can assist scheduling more accurately, because the scheduled time domain resource unit is the time domain resource within a frame, so it is more targeted and the effect is better.

[0296] Example 3

[0297] Embodiment 3 shows a schematic diagram of an embodiment of a wireless protocol architecture of a user plane and a control plane according to the present application, as shown in the attached Figure 3 shown. Figure 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane 350 and a control plane 300, Figure 3The radio protocol architecture of the control plane 300 for a first node (UE, gNB) and a second node (gNB, UE), or between two UEs is shown 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 as PHY301 herein. Layer 2 (L2 layer) 305 is above PHY301 and is responsible for the link between the first node and the second node and the two UEs through PHY301. The 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 by encrypting data packets, and provides support for inter-zone mobility of the first node between the second node. 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 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) in the control plane 300 is responsible for obtaining radio resources (i.e., radio bearers) and configuring the lower layer using RRC signaling between the second node and the first node. The PC5-S (PC5 Signaling Protocol) sublayer 307 is responsible for processing 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). The radio protocol architecture for the first node and the second node in the user plane 350 is substantially the same as the corresponding layers and sublayers in the control plane 300 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, 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 also includes a SDAP (Service Data Adaptation Protocol) sublayer 356, which is responsible for mapping between QoS flows and data radio bearers (DRBs) to support the diversity of services. SRB can be regarded as a service or interface provided by the PDCP layer to a higher layer, such as the RRC layer. In the NR system, SRBs include SRB1, SRB2, and SRB3, which are used to transmit different types of control signaling. 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 has a special meaning for the UE. After each UE establishes an RRC connection, there will be SRB1 for transmitting RRC signaling. Most of the signaling is transmitted through SRB1. If SRB1 is interrupted or cannot be used, the UE must perform RRC reconstruction. SRB2 is generally only used to transmit NAS signaling or signaling related to security. The UE may not configure SRB3. Except for emergency services, the UE must establish an RRC connection with the network for subsequent communication. Although not shown, the first node may have several upper layers above the L2 layer 355. Also included are 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., remote UE, server, etc.).

[0304] As an embodiment, the second scheduling information in the present application is generated in PHY301.

[0305] Example 4

[0306] 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 attached figure. Figure 4 shown. Figure 4 is a block diagram of a first communication device 450 and a second communication device 410 communicating with each other in an access network.

[0307] The first communication device 450 includes a controller / processor 459, a memory 460, a data source 467, a transmit processor 468, a receive processor 456, and may optionally also include a multi-antenna transmit processor 457, a multi-antenna receive processor 458, a transmitter / receiver 454 and an antenna 452.

[0308] The second communication device 410 includes a controller / processor 475 , a memory 476 , a receiving processor 470 , a transmitting processor 416 , and may optionally also include a multi-antenna receiving processor 472 , a multi-antenna transmitting processor 471 , a transmitter / receiver 418 and an antenna 420 .

[0309] In the transmission from the second communication device 410 to the first communication device 450, at the second communication device 410, the 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 to the first communication device 450 based on various priority metrics. The controller / processor 475 is also responsible for the 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 coding and interleaving to facilitate forward error correction (FEC) at the second communication device 410, as well as 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, including codebook-based precoding and non-codebook-based precoding, and beamforming processing on the coded and modulated symbols to generate one or more spatial streams. The transmit processor 416 then maps each spatial stream to a subcarrier, multiplexes it with a reference signal (e.g., a pilot) in the time domain and / or frequency domain, and then uses an inverse fast Fourier transform (IFFT) to generate a physical channel carrying a time-domain multi-carrier symbol stream. The multi-antenna transmit processor 471 then performs a transmit analog precoding / beamforming operation 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.

[0310] 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 a signal through its corresponding antenna 452. Each receiver 454 recovers the information modulated onto the RF carrier and converts the RF stream into a baseband multi-carrier symbol stream and provides it to the receiving processor 456. The receiving processor 456 and the multi-antenna receiving processor 458 implement various signal processing functions of the L1 layer. The multi-antenna receiving processor 458 performs a receiving analog precoding / beamforming operation on the baseband multi-carrier symbol stream from the receiver 454. The receiving processor 456 uses a fast Fourier transform (FFT) to convert the baseband multi-carrier symbol stream after the receiving analog precoding / beamforming operation 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 receiving processor 456, wherein the reference signal will be used for channel estimation, and the data signal is recovered after multi-antenna detection in the multi-antenna receiving processor 458 to any spatial stream destined for the first communication device 450. The symbols on each spatial stream are demodulated and recovered in the receiving processor 456, and soft decisions are generated. The receiving processor 456 then 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. The upper layer data and control signals are then provided to the controller / processor 459. The controller / processor 459 implements the functions of the L2 layer. The controller / processor 459 may be associated with a memory 460 that stores program codes 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 multiplexing between transport and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover the upper layer data packets from the core network. The upper layer data packets are then provided to all protocol layers above the L2 layer. Various control signals may also be provided to L3 for L3 processing.

[0311] 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 the controller / processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to the transmission function at the second communication device 410 described 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 user plane and control plane. The controller / processor 459 is also responsible for the retransmission of lost packets and signaling to the second communication device 410. The transmit processor 468 performs modulation mapping and channel coding processing, and the multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming processing. Then, the transmit processor 468 modulates the generated spatial stream into a multi-carrier / single-carrier symbol stream, which is then provided to different antennas 452 via the transmitter 454 after analog precoding / beamforming operations in the multi-antenna transmit processor 457. 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.

[0312] In the transmission from the first communication device 450 to the second communication device 410, the function at the second communication device 410 is similar to the reception function at the first communication device 450 described in the transmission from the second communication device 410 to the first communication device 450. Each receiver 418 receives a radio frequency signal through its corresponding antenna 420, converts the received radio frequency signal into a baseband signal, and provides the baseband signal to the multi-antenna reception processor 472 and the reception processor 470. The reception processor 470 and the multi-antenna reception processor 472 jointly implement the functions of the L1 layer. The controller / processor 475 implements the L2 layer functions. The controller / processor 475 can be associated with a memory 476 storing program codes and data. The memory 476 can 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 multiplexing between transport and logical channels, packet reassembly, decryption, header decompression, control signal processing to recover the upper layer data packets from the UE 450. Upper layer packets from controller / processor 475 may be provided to the core network.
