Description

Method for transmitting UE capability information supporting NR-U and its user equipment

The embodiments of the present invention generally relate to wireless communication, and, more specifically, to support UE capability signaling methods of 5G unlicensed spectrum (New Radio in unlicensed spectrum, NR-U).

Over the years, wireless communication networks have grown exponentially. Long-Term Evolution (LTE) systems have higher peak data rates, lower latency, improved system capacity, and lower operating costs due to simplified network architecture. The LTE system (also known as the 4G system) also provides seamless integration with old wireless networks (for example, GSM, CDMA, and Universal Mobile Telecommunication System (UMTS)). In the LTE system, the evolved universal terrestrial radio access network (E-UTRAN) includes multiple evolutions that communicate with multiple mobile stations called user equipment (UE). Node B (evolved Node-B, eNodeB or eNB). The 3rd generation partner project (3GPP) network usually includes the integration of 2G/3G/4G systems. With the optimization of network design and the development of various standards, many improvements have been formed. The Next Generation Mobile Network (NGMN) committee has decided to focus future NGMN activities on defining the end-to-end requirements of the 5G new radio (NR) system.

In the 3GPP version 16 (release 16) specification, support for 5G NR operating in unlicensed spectrum is introduced (this function is also called NR-U), which brings flexible use of unlicensed spectrum to 5G The many choices. NR-U supports license-assisted use of unlicensed spectrum and independent use of unlicensed spectrum. Specifically, independent NR-U enables 5G to be deployed through small cell deployment and can be operated by any vertical end user without obtaining a licensed spectrum. This new feature will allow 5G NR to utilize the 5GHz global frequency band and the 6GHz frequency band, thereby significantly increasing the spectrum coverage of 5G.

Unlike licensed spectrum, any operator can access unlicensed frequency bands as long as they comply with regulations. Since there is no coordination between operators, it may happen that two cells deployed by two different operators are assigned the same physical cell ID. Therefore, the network may need the assistance of the UE to obtain system information of neighboring cells in order to learn more about cells deployed on unlicensed frequency bands (also referred to as unlicensed cells). However, according to the current 3GPP specifications and/or compliance with 5G/NR requirements, the network cannot know whether the UE supports obtaining UE capability information for the system information of unauthorized cells.

Seek a solution.

A method of UE capability information signaling supporting NR-U is proposed. The UE transmits the UE capability information to the mobile communication network, where the UE capability information includes whether the UE supports the acquisition of system information of unauthorized cells. The UE receives the configuration from the serving cell of the mobile communication network, where the configuration includes information obtained from the system information of one or more unauthorized cells on the frequency. The UE obtains the system information of the one or more unauthorized cells on the frequency; and reports the obtained system information to the serving cell, or stores the obtained system information in the UE.

In one embodiment, reporting the acquired system information to the serving cell is performed in response to the serving cell requesting the UE to perform a CGI report. In another embodiment, it is executed to store the obtained data in the UE Get the system information in response to the UE's handover from the serving cell to the unauthorized cell. In another embodiment, storing the acquired system information in the UE is performed in response to the UE receiving an indication that the system information of one or more unauthorized cells on the frequency has been changed.

In one example, the UE capability information is set and reported according to each frequency band. The system information includes at least one of MIB and SIB1. SIB1 includes CGI, and the CGI includes at least one of PLMN ID and PCI. UE capability information includes: whether the UE supports obtaining the first indicator of MIB on an unauthorized cell, whether the UE supports obtaining the second indicator of SIB1 on an unauthorized cell, and whether the UE supports CGI information from neighboring unauthorized cells The third indicator of acquisition. Unlicensed cells are unlicensed neighboring cells based on NR, and serving cells are authorized cells based on NR.

In another example, the UE receives a UE capability query message from the serving cell and sends a UE capability information message to the serving cell in response to receiving the UE capability query message, wherein the UE capability information is transmitted through the UE capability information message.

A UE that supports NR-U UE capability information transmission is proposed. The UE includes a transmitter for transmitting UE capability information to the mobile communication network, where the UE capability information includes: whether the UE supports the acquisition of system information of unauthorized cells. The UE also includes a receiver for receiving a configuration from a serving cell of the mobile communication network, wherein the configuration includes information for obtaining system information of one or more unauthorized cells on a frequency. The receiver is also used to obtain the system information of the one or more unauthorized cells on the frequency. The UE further includes a system information acquisition circuit for reporting the acquired system information to the serving cell or storing the acquired system information in the UE.

The present invention provides a method for supporting NR-U UE capability information transmission and its user equipment. With UE assistance, the serving cell obtains the system information of the unauthorized cell and the beneficial effect of configuring the UE for the unauthorized cell. .

Reference is now given in detail to some embodiments of the present invention, examples of which are described in the accompanying drawings.

Figure 1 shows an exemplary mobile communication network 100 supporting unlicensed spectrum according to a novel aspect. The mobile communication network 100 can be a 5G NR network. The 5G NR network includes a user equipment (UE )110. The access network 120 is connected to the 5G core network 130 through the NG interface, and more specifically, is connected to the User Plane Function (UPF) through the NG user-plane (NG-u) part , And through the NG control plane (NG The control-plane (NG-c) part is connected to the Mobility Management Function (AMF). For load sharing and redundancy purposes, one gNB can be connected to multiple UPF/AMF.

In addition to the gNB 121, there are multiple gNBs around the UE 110, including the gNB 101 and the gNB 102 operating in an unlicensed frequency band (for example, 5 GHz or 6 GHz). Each of gNB 101 and gNB 102 may be deployed by the same operator as gNB 121, or may be deployed by an operator different from the operator of gNB 121. The gNB 121 can form at least one cell, which can be referred to as an NR-based authorized cell (ie, a cell operating in a 5G NR authorized frequency band). Similarly, each of gNB 101 and 102 may form at least one cell, which may be referred to as an NR-based unlicensed cell (ie, a cell that operates on an unlicensed frequency band).

The UE 110 may be a smart phone, a wearable device, an Internet of Things (IoT) device, a tablet computer, etc., and may or may not support the acquisition of system information on unauthorized cells.

According to a novel aspect, if UE 110 supports system information acquisition on unauthorized cells and camps on a cell formed by gNB 121 (e.g., primary cell (PCell) or primary and secondary cell (PSCell)), then UE 110 can be in the UE In the capability transfer process, the UE capability is transferred to the serving cell about whether the UE 110 supports the acquisition of the system information of the unauthorized cell. Then, the gNB 121 configures the UE 110 to obtain the system information of one or more unauthorized cells on the frequency, and the UE 110 reports the obtained system information to the serving cell or stores the obtained system information in the UE 110.

Specifically, the system information includes at least one of a master information block (Master Information Block, MIB) and a system information block type 1 (System Information Block type 1, SIB1). In particular, SIB1 includes Cell Global Identity (CGI), where CGI includes at least one of Public Land Mobile Network Identity (PLMN ID) and Physical Cell Identity (PCI) . Using the CGI included in the reported system information, the mobile communication network 100 can learn about changes in unauthorized communities Multi-information, and can solve the problem that two or more unauthorized cells deployed by different operators happen to be assigned the same PCI.

To further clarify, in 5G NR, system information can be divided into three categories, including Minimum System Information (MSI) and Other System Information (OSI). MSI includes MIB and Remaining Minimum System Information (RMSI) including SIB1, while OSI includes other SIBs, including SIB2~SIB9.

In one embodiment, the UE 110 may receive the configuration of the system information acquisition for one or more neighboring unauthorized cells on the frequency from the serving cell via a radio resource control (RRC) connection reconfiguration message, and request UE 110 performs CGI report according to the received configuration.

In another embodiment, the UE 110 may receive a configuration for acquiring system information for at least one target unlicensed cell on the frequency from the serving cell via a handover command (for example, an RRC connection reconfiguration message), and the UE 110 is requested according to all The received configuration performs handover from the serving cell to the target unlicensed cell. Then, the UE 110 obtains the system information of the target cell in response to the handover, and locally stores the obtained system information.

In another embodiment, the UE 110 may receive the configuration obtained by the system information for one or more unauthorized cells on the frequency from the serving cell via a message, the message including the system of one or more unauthorized cells on the frequency An indication that the information has changed, and the UE is requested 110 to perform MIB reading and SIB1 reading according to the received configuration. Then, the UE 110 obtains the new system information and stores the new system information locally.

Figure 2 shows a simplified block diagram 200 of a wireless device (e.g., UE 201 and gNB 211) according to an embodiment of the present invention. The gNB 211 has an antenna 215 for transmitting and receiving radio signals. The radio frequency RF transceiver module 214 (including the receiver and the transmitter) coupled to the antenna 215 is connected from the antenna 215 Receive the RF signal, convert the RF signal to a baseband signal, and then send the baseband signal to the processor 213. The RF transceiver module 214 also converts the baseband signal received from the processor 213, converts the baseband signal into an RF signal, and then sends it to the antenna 215. The processor 213 processes the received baseband signal and calls different functional modules to execute the functions in the gNB 211. The memory 212 stores program instructions and data 220 to control the operation of the gNB 211. In the example in FIG. 2, the gNB 211 also includes a protocol stack 280 and a set of control function modules and circuits 290. The protocol stack 280 includes a NAS layer for communicating with AMF/SMF/MME entities connected to the core network, a Radio Resource Control (RRC) layer for high-level configuration and control, and a packet data convergence protocol (Packet Data Convergence). Protocol, PDCP)/Radio Link Control (Radio Link Control, RLC) layer, Media Access Control (MAC) layer and Physical (PHY) layer. In one example, the control function module and circuit 290 includes: a UE capability information query circuit 291 for querying UE capability information of the UE 201; and a system information request circuit 292 for preparing the configuration of one or more unauthorized cells for system information acquisition .

Similarly, the UE 201 has a memory 202, a processor 203, and an RF transceiver module 204. The RF transceiver module 204 is coupled to the antenna 205, receives the RF signal from the antenna 205, converts the RF signal to the baseband signal, and sends the baseband signal to the processor 203. The RF transceiver module 204 also converts the baseband signal received from the processor 203 into an RF signal, and sends the RF signal to the antenna 205. The processor 203 processes the received baseband signal, and calls different functional modules and circuits to execute the functions in the UE 201. The memory 202 stores programs and data instructions 210 executed by the processor 203 to control the operation of the UE 201. By way of example, suitable processors include dedicated processors, digital signal processors (digital signal processors, DSP), multiple microprocessors, and DSP cores, controllers, microcontrollers, and dedicated integrated circuits (application specific integrated circuits). One or more microprocessors and/or state machines associated with integrated circuits (ASIC), file programmable gate array (FPGA) circuits, and other types of integrated circuits (IC). And software The associated processor can be used to implement and configure UE 201 features.

The UE 201 also includes a protocol stack 260 and a set of control function modules and a control circuit 270. The protocol stack 260 includes a NAS layer for communicating with AMF/SMF/MME entities connected to the core network, an RRC layer for high-level configuration and control, a PDCP/RLC layer, a MAC layer, and a PHY layer. The control function module and the circuit 270 can be implemented and configured through software, firmware, hardware, and/or a combination thereof. When the processor 203 executes the function module and the circuit 270 via the program instructions included in the memory 202, the control function module and the circuit interact with each other to allow the UE 201 to execute the embodiment in the network, as well as the functional tasks and features .

In one example, the control function module and circuit 270 includes a UE capability information processing circuit 271 that provides information about whether the UE 201 supports the acquisition of system information of an unauthorized cell and processes the acquired system information of the unauthorized cell (for example, to the serving cell Report the acquired system information, or store the acquired system information in the system information acquisition circuit 272 of the UE.

Figure 3 shows the sequence flow of UE capability signaling supporting NR-U between UE 301 and the 5G NR network according to a novel aspect. In step 311, the UE 301 receives a UE CapabilityEnquiry message from the 5G NR network. When the 5G NR network needs (additional) UE radio access capability information, the 5G NR network can initiate the process to the UE in the RRC connection (RRC_CONNECTED). The 5G NR network should only acquire UE capabilities after the access layer (Access Stratum, AS) security is activated. In step 321, the UE 301 prepares UE capability information, the UE capability information including information on whether the UE 301 supports the acquisition of system information of an unauthorized cell. Specifically, the UE capability information may include: whether the UE 301 supports acquiring the first indicator of MIB on an unauthorized cell (for example, "mib-Acquisition-r16" IE); whether the UE 301 supports acquiring SIB1 on an unauthorized cell The second indicator (for example, "sib1-Acquisition-r16" IE) and the third indicator (for example, "cgi-Acquisition-r16" IE) whether the UE 301 supports obtaining CGI information from neighboring unauthorized cells. In step 331, the UE 301 sends to the 5G NR network information including UE capability information UECapabilityInformation message.

Figure 4 shows the sequence flow for CGI acquisition and reporting between the UE 401 and the 5G NR network according to a novel aspect. In step 411, the UE 401 receives an RRC reconfiguration (RRCReconfiguration) message with a configuration, the configuration including information for obtaining system information of one or more unauthorized cells on the frequency. In an example, the configuration may be included in the "reportCGI-RequestNR" IE or "reportCGI-RequestEUTRA" IE specified in 3GPP TS 38.331 (v16.3.1). In step 421, the UE 401 sends an RRC reconfiguration complete (RRCReconfigurationComplete) message to the 5G NR network. In step 431, the UE 401 obtains the system information of the unauthorized cell on the frequency. In step 441, the UE 401 reports the acquired system information to the 5G NR network.

To further clarify, the system information acquisition referred to in this article aims to read the CGI information carried in SIB1. In order to read SIB1, the UE first needs to read the MIB of the Physical Downlink Control Channel (PDCCH) configuration (for example, CORESET # 0 and Type 0-PDCCH configuration) carrying SIB1. Please note that in NR-U, transmission is subject to Listen Before Talk (LBT) results. In order to increase the possibility of successfully transmitting the synchronization signal/physical broadcast channel (SS/PBCH) block, the concept of the discovery burst window is introduced in NR-U to increase the transmission chance of a given SS/PBCH block. Therefore, the UE needs to monitor multiple locations within the burst window to read the PBCH of a given SS/PBCH block. Compared with the licensed frequency band, this will complicate the UE's PBCH reading process.

More specifically, the discovery burst refers to a DL transmission burst, which includes a collection of signals and/or channels confined in a window and associated with a duty cycle. The discovery burst can be any of the following: (1) Transmission initiated by the eNB, including Primary Synchronization Signal (PSS), Secondary Synchronization Signal (SSS) and Cell-specific Reference Signal (Cell-specific Reference) Signal, CRS), and can include non-zero power CSI Reference signal (CSI-RS); (2) Transmission initiated by gNB, including at least one SS/PBCH area composed of PSS, SSS, PBCH and related demodulation reference signal (De-Modulation Reference Signal, DM-RS) Block, and may also include a control resource set (CORESET), used for PDCCH with SIB1 scheduled PDSCH and PDSCH with SIB1 and/or non-zero power CSI-RS.

When the SS/PBCH block is located in the sync-raster, the UE determines the CORESET # 0 frequency position in the same way as the version 15 (R15) authorized operation. Specifically, the UE reads the PBCH in the SS/PBCH block, and uses the information carried in the MIB (k _SSB and SSB-CORESET0 PRB) to determine the frequency offset between the SS/PBCH block and CORESET #0. In one embodiment, K _SSB is the carrier number offset between subcarrier 0 of SSB and subcarrier 0 of CRB to calculate the first subcarrier of SSB and the first subcarrier of CORESET#0 (used to schedule RMSI) Sub-carrier level offset between sub-carriers. On the other hand, when the SS/PBCH block is not in the synchronization grid, the UE has to determine the frequency position of CORESET # 0 in a more complicated way. Specifically, for a given frequency SSB that deviates from the synchronization grid, the UE determines which LBT subband the SSB is in. Next, the UE determines the frequency of the SSB on the synchronization grid for the LBT subband. Then, the UE reads the PBCH from the SSB that deviates from the synchronization grid, and uses the indicated k _SSB and SSB-CORESET0 PRB offset to determine the position of CORESET0, just like the SSB is sent on the synchronization grid point.

Figure 5 shows the sequence flow for CGI acquisition between the UE 501 and the 5G NR network according to a novel aspect. In step 511, the UE 501 receives an RRCReconfiguration message with a configuration from the serving cell on the licensed frequency band (i.e., the source cell), where the configuration includes information for handover of the UE 501 from the serving cell to the target cell on the unlicensed frequency band . In step 521, the UE 501 performs a random access procedure to the target cell. In step 531, the UE 501 sends an RRC reconfiguration complete (RRCReconfigurationComplete) message to the target cell after successfully completing the random access process. In step 541, the UE 501 obtains the system information of the target cell on the unlicensed frequency band. In other words, since the acquisition of system information is triggered by the configuration of the switching information, the configuration of the switching information can also be solved. Interpretation is obtained by system information for configuration. In step 551, the UE 501 locally stores the acquired system information.

In an example, the system information acquisition includes at least SIB1 reading, so that the UE 501 can obtain the CGI from the SIB1 and determine whether the target cell and the source cell belong to the same PLMN. If the target cell and the source cell belong to the same PLMN, the UE 501 can determine to handover to the target cell.

Figure 6 shows the sequence flow for CGI acquisition between the UE 601 and the 5G NR network according to a novel aspect. In step 611, the UE 601 receives an RRCReconfiguration message with a configuration from the serving cell, where the configuration includes information used for obtaining system information of one or more unauthorized cells on the frequency. In one example, the serving cell may be PCell or PSCell. In step 621, the UE 601 sends an RRCReconfigurationComplete message to the serving cell. In step 631, the UE 601 obtains the system information of the unlicensed cell on the frequency. In step 641, the UE 601 reports the obtained system information report to the serving cell. In step 651, the UE 601 receives a message from the serving cell (for example, via paging), where the message includes an indication that the system information of the unauthorized cell on the frequency has been changed/modified. In step 661, the UE 601 performs MIB reading and SIB1 reading to obtain new system information. In step 671, the UE 601 stores the new system information locally.

Figure 7 is a flowchart of a method for UE capability signaling to support NR-U according to a novel aspect. In step 701, the UE transmits UE capability information to the mobile communication network, where the UE capability information includes information about whether the UE supports the acquisition of system information on unauthorized cells. In step 702, the UE receives a configuration from a serving cell of the mobile communication network, where the configuration includes information for obtaining system information of one or more unauthorized cells on the frequency. For example, the UE capability information in step 701 may be transferred to the same serving cell as the serving cell from which the configuration was received in step 702. Alternatively, the UE capability information in step 701 may be transferred to a serving cell different from the serving cell from which the configuration is received in step 702. In step 703, the UE obtains system information of one or more unauthorized cells on the frequency. In step 704, the UE reports the acquired system information to the serving cell, or stores the acquired system information in the UE.

In one example, the UE capability information is set and reported according to each frequency band or each frequency band combination. In an example, the system information includes at least one of MIB and SIB1, and SIB1 includes CGI, and the CGI includes at least one of PLMN ID and PCI. In one example, the UE capability information includes: whether the UE supports obtaining the first indicator of MIB on an unauthorized cell, whether the UE supports obtaining the second indicator of SIB1 on an unauthorized cell, and whether the UE supports the second indicator of SIB1 from a neighboring cell. The third indicator to authorize the acquisition of CGI information of the community. In one example, the unlicensed cell is an unlicensed neighboring cell based on NR, and the serving cell is an authorized cell based on NR. In one example, the UE receives a UE capability query message from the serving cell and sends a UE capability information message to the serving cell in response to receiving the UE capability query message, wherein the UE capability information is transmitted through the UE capability information message.

In one embodiment, reporting the acquired system information to the serving cell is performed in response to the serving cell requesting the UE to perform a CGI report.

In another embodiment, storing the acquired system information in the UE is performed in response to the UE's handover from the serving cell to one of the unauthorized cells.

In another embodiment, storing the acquired system information in the UE is performed in response to the UE receiving an indication that the system information of one or more unauthorized cells on the frequency has been changed.

Although for illustrative purposes, the present invention has been described in conjunction with specific embodiments, the present invention is not limited thereto. Therefore, without departing from the scope of the present invention described in the scope of the patent application, various modifications, adaptations, and combinations can be implemented to the various features of the described embodiments.
