Description

Background Art

[0002] When a base station adopting a CU / DU separation architecture supports uplink and downlink multi-carrier aggregation, the following problems exist for the change of the DC subcarrier position with the BWP / carrier activation / deactivation configuration:

[0003] 1) The gNB-DU, a centralized entity in the base station, cannot know the uplink and downlink subcarrier positions used by the terminal side: Currently, the 38.473 protocol does not support the situation where the CU notifies the DU of the terminal's reported subcarrier position. Therefore, the base station cannot accurately know the DC subcarrier position of the terminal, nor can it determine whether to configure the terminal's DC subcarrier to transmit SRS or schedule PDSCH / PUSCH and other services. Incorrect configuration and resource scheduling will lead to greater interference or waste of resources.

[0004] 2) The base station separation entity gNB-DU cannot know which RRC protocol version reporting mode is used on the terminal side: the current protocol only configures the DC subcarrier position of a single carrier, while the air interface protocol of the 5G system supports different carrier configuration reporting schemes (single carrier reporting, dual carrier reporting or multi-carrier reporting), resulting in the base station being unable to perform relevant resource configuration based on different reporting modes.

[0005] 3) During the NSA (Non-Standalone Architecture) configuration process, the DC subcarrier position information of the terminal cannot be forwarded to the SN (Secondary Node) through the MN (Master Node): When the secondary base station adopts carrier aggregation, the carrier aggregation or MR-DC combination of the relevant secondary base station and the master node needs to be sent to the secondary base station, but the multi-carrier configuration information is currently missing in the node transmission message.

[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0072] Before describing in detail the specific implementation of the embodiments of the present disclosure, the application scenarios of the embodiments of the present disclosure are first introduced.

[0073] The DC subcarrier is an unused subcarrier at the center of the downlink carrier in the OFDM system. Figure 1 As shown in the figure, the DC subcarrier is set to avoid high interference caused by possible leakage of the local crystal oscillator. In the communication protocol of the LTE system, it is defined that the DC subcarrier is not used. This is because the DC subcarrier is greatly affected by interference (such as local crystal oscillator deviation). Since LTE terminals use the entire 20MHz bandwidth and the center frequency of the frequency band is located at the center of the 20MHz bandwidth, it is a common practice not to use the DC subcarrier.

[0074] In the 5G system, the NR protocol needs to support a wider spectrum, not only traditional low-frequency bands (such as bands less than 3GHz), but also millimeter wave bands (currently 5G in 3GPP can support up to 71GHz). Due to cost and complexity considerations, 5G terminals do not have to support all these bands. Some 5G terminals can only support part of the bandwidth, and in order to use a band more efficiently, the bandwidth used by the terminal is not necessarily symmetrically distributed relative to the center frequency of the band, which leads to different DC subcarrier usage strategies for 5G systems and LTE systems. Since the position of the DC subcarrier in the 5G system is not fixed within the frequency band, the implementation method of not using the DC subcarrier will be very complicated. Therefore, in the 5G system, the DC subcarrier must continue to be used for the transmission of user data or control signals, but the performance degradation caused by the DC subcarrier in some cases must also be tolerated.

[0075] For the DC subcarrier of the receiver (terminal), the transmitter (base station) should be aware that the receiver DC subcarrier may conflict with the RS used by the receiver. If the transmitter does not obtain the DC subcarrier of the receiver, the transmitter can map the DMRS signal to the DC subcarrier of the receiver for downlink transmission or uplink transmission. Therefore, the transmitter should be implicitly informed of the location of the receiver DC subcarrier through the specification. In addition, if different UEs access the NR system on different frequency regions of the same NR carrier, there will be multiple virtual receiver DC subcarriers in one system, such as Figure 2 As shown, a system may contain multiple potential positions of the virtual receiver DC subcarrier corresponding to different UE frequency regions, and the actual position of the virtual receiver DC subcarrier will depend on the access status of the UE in the carrier. In order to avoid potential conflicts between RS and DC subcarrier, it is necessary to define candidate positions of the DC subcarrier.

[0076] Figure 3 The corresponding DC subcarrier position under different BWP configurations is shown, such as Figure 3 As shown in FIG. 1 , from the perspective of the entire system, the candidate position of the DC subcarrier may be distributed to any PRB in the system bandwidth. However, from the perspective of the PRB, some specific subcarriers in the PRB can be regarded as the candidate position of the DC subcarrier. The candidates for the DC subcarrier may be different and may depend on the even / odd number of PRBs in the receiver bandwidth.

[0077] Figure 4 The corresponding DC subcarrier position under different PRB numbers is shown, such as Figure 4 As shown, the subcarriers in the PRB are numbered sequentially from 0 to 11. Considering that the DC subcarrier is more likely to be located at the center of the transmit / receive bandwidth, when the number of PRBs in the transmit / receive bandwidth is an odd number, the candidate position of the DC subcarrier in the PRB can be a subcarrier numbered 5 or 6; when the number of PRBs in the transmit / receive bandwidth is an even number, the candidate for the DC subcarrier should be located at the boundary of the PRB, and the candidate position of the DC subcarrier in the PRB can be a subcarrier numbered 0 or 11.

[0078] For the use of DC subcarrier, the solution defined in the 3GPP Rel-15 version protocol is: using the terminal to report semi-static signaling, that is, the network instructs the terminal to report the location of its uplink DC subcarrier, and then the terminal side carries the specific location of its DC subcarrier in each configured BWP in the RRC reconfiguration completion message. The implementation method of carrying the DC subcarrier location in the RRC reconfiguration completion message is as follows: ① In the uplink direction, an independent bit is used to indicate whether there is a 7.5KHz uplink offset, and 12 bits are used to indicate the specific location of the Tx DC location, as shown in Table 1. ② In the downlink direction, 12 bits are used to indicate the specific location of the Tx DC location, as shown in Table 2.

[0079] Table 1

[0080] Table 2

[0081] In the Rel-16 stage, a reporting method is added to support the aggregation of two uplink carriers. The network side instructs the terminal to report its location through signaling, and the terminal reports the uplink DC subcarrier position of the two carriers through the RRC reconfiguration completion message or the RRC recovery completion message. Compared with the solution in the Rel-15 stage, only the uplink carrier aggregation method is supported here and the number of carriers is controlled at 2 carriers. The configuration information includes:

[0082] ① The cell ID and BWP ID of each carrier and the configuration of whether the BWP is activated

[0083] ② When the terminal architecture supports single PA or dual PA architecture, the position is reported, including the reference carrier identifier of the DC subcarrier, whether it contains 7.5kHz, and 3302 potential position identifiers.

[0084] Specific ASN.1 configuration information such as Figure 5 shown.

[0085] Theoretically, there are 64 different DC subcarriers according to different subcarrier spacing and BWP combinations. In the Rel-17 stage, more uplink carrier aggregation and multiple downlink carrier aggregation with only a single uplink need to be considered, so the traditional reporting method and DC subcarrier position calculation method need to be updated.

[0086] First, the uplink and downlink directions are limited by factors such as the number of carriers, subcarrier spacing, BWP, and whether the carrier and BWP are activated, resulting in differences in the position of the DC subcarrier in different directions of the terminal, such as Figure 6As shown in the figure, it is assumed that the terminal uplink PA supports a larger bandwidth. In the uplink direction, there are only three carriers, of which carrier 2 is not activated, and only carriers 1 and 3 are activated, so the DC subcarrier is located in carrier 2. In the downlink direction, carriers 2 and 4 are activated, so the default DC subcarrier is located outside carrier 2. At the same time, the default subcarrier position is also related to the terminal's RF hardware architecture, such as Figure 7 The figure shows the corresponding DC subcarrier positions under different terminal hardware architectures. When the broadband capability supported by the terminal is large and one PA can be used to support all bandwidths, there is only one DC subcarrier position. If the terminal uses two PAs to support a larger bandwidth, there are two DC subcarrier positions.

[0087] The NSA architecture is an effective 4G / 5G compatible solution in the process of 5G evolution. The 5G NR base station and the LTE base station together provide dual-connection services to the UE. The LTE base station is the primary base station and the 5G NR base station is the secondary base station. The multiple cells provided by LTE are the MCG (Master Cell Group), and the multiple cells provided by 5G NR are the SCG (Secondary Cell Group).

[0088] In the 5G stage, SUL (Supplementary Uplink) is also introduced to increase the rate and enhance the uplink coverage. Carrier aggregation (CA) refers to the technology of increasing data rate and capacity by combining multiple independent carrier channels to increase bandwidth. Carrier aggregation is divided into three combinations: intra-band continuous, intra-band non-continuous, and inter-band non-continuous, and the implementation complexity increases successively. If the two carriers have the same frequency band, are close to each other, and have continuous spectrum, it is called intra-band continuous carrier aggregation. If the two carriers have the same frequency band, but the spectrum is not continuous, and there is a gap in the middle, it is called intra-band discontinuous carrier aggregation. If the two carriers have different frequency bands, it is called inter-band carrier aggregation.

[0089] In addition, 5G wireless networks also introduce CU / DU architecture, such as Figure 8 The figure shows a schematic diagram of a base station architecture with CU and DU separated in an embodiment of the present disclosure. The division of CU and DU is performed based on the real-time requirements of different protocol layers. In the base station architecture with CU and DU separated, the physical layer, MAC layer, and RLC layer functions with high real-time requirements in the original BBU are placed in the DU for processing, while the PDCP layer and RRC layer functions with low real-time requirements are placed in the CU for processing, and the F1 interface is used between the CU and DU. For the RRC connection recovery process, when the CU and DU separation architecture is adopted, the relevant signaling processing process is as follows: Fig. 9 shown.

[0090] Based on the above requirements and reasons, the current 3GPP Rel-17 protocols cannot meet the requirements for terminal DC subcarrier position reporting in the separation architecture and NSA scenarios. It is necessary to enhance the functions through new standardized methods to meet the needs of network deployment and optimization.

[0091] To support the enhancement of uplink capacity of 5G networks, the aggregation of more carriers can effectively improve the system uplink capacity, increase terminal throughput, effectively utilize carrier resources, and reduce the interference of DC subcarriers on other subcarriers. A resource configuration method for a multi-carrier aggregation system is provided in the disclosed embodiment to support the DC subcarrier position feedback by the transmission terminal in a separated architecture and an NSA system, thereby facilitating the base station physical layer to determine the relevant resource locations and perform correct resource scheduling, thereby improving system efficiency and user experience.

[0171] Combination Figure 18 to Figure 20 Signaling interaction flow, two specific scenarios are listed below to illustrate the user plane configuration method for supporting low-latency services provided in the embodiment of the present disclosure:

[0172] Example 1: Mainly describes an SA deployment scenario in which the base station gNB#1 (first base station) adopts a CU / DU separation architecture, the UE supports multi-carrier uplink transmission DC carrier reporting, and the UE is configured with two uplink carriers CC#1 and CC#2 by the base station gNB#1. The two carriers have the same bandwidth. The UE, in accordance with the network instructions, respectively feeds back the activation of BWP1 of CC#1 and BWP2 of CC#2, as well as the location information of the uplink DC subcarrier when only BWP#1 is activated, and indicates to the network in the RRC reconfiguration completion message whether the subcarriers determined by the base station separation entity gNB#1-DU after deactivating #BWP#2 through MAC CE can be applied to DMRS and CSI-RS subcarriers.

[0173] 1) The UE reports the UE's support for DC subcarrier reporting to the core network through a NAS message, and the support includes the following capabilities:

[0174] Support serving cell and BWP uplink transmission DC carrier reporting: yes;

[0175] Support dual carrier uplink transmission DC carrier reporting: yes;

[0176] Supports multi-carrier uplink transmission DC carrier reporting: Yes.

[0177] 2) When gNB#1 needs to configure or adjust the UE carrier or BWP configuration, the RRC reconfiguration request message for requesting the UE to perform the DC subcarrier reporting mode is determined based on the UE's reported UE capabilities and the RRC version supported by gNB#1-DU (the first base station separation entity). The RRC reconfiguration request message is used to request the UE to feedback the first DC subcarrier configuration set it supports in the RRC reconfiguration completion message. Since the UE supports multi-carrier uplink transmission DC carrier reporting and the RRC version of gNB#1-DU supports v17.3.0, the reporting mode is set to support multi-carrier uplink transmission DC carrier reporting. The reporting mode information carried in the primary cell set information in the RRC reconfiguration request message includes:

[0178] Multi-carrier uplink transmission DC carrier reporting: The specific information includes the intra-band uplink carrier aggregation configuration of CC#1 and CC#2. The intra-band uplink carrier aggregation configuration includes but is not limited to the following information:

[0180] · Two carrier aggregation configuration cases: the first case is {BWP#1 activated, BWP#2 activated}, and the second case is {BWP#1 activated, CC#2 deactivated}.

[0181] 3) gNB#1-CU (first base station centralized entity) places the RRC reconfiguration request message in the downlink RRC forwarding message (first RRC message) and sends it to gNB#1-DU through the F1 interface.

[0182] 4) gNB#1-DU carries the RRC reconfiguration request message in the downlink RRC forwarding message (second RRC message) and sends it to the UE.

[0183] 5) After the UE receives the second RRC message, when the reporting mode in the primary cell set information is "multi-carrier uplink transmission DC carrier reporting" information, the location information of the third uplink DC subcarrier of all uplink cells currently on the MCG and / or SCG is determined, and the location information of the third uplink DC subcarrier of each uplink cell includes:

[0184] A carrier combination information includes the following:

[0185] · Lower limit of serving cell identification: CC#1;

[0186] · Upper limit of serving cell identification: CC#2;

[0188] 6) The UE sends the DC subcarrier reporting result requested by the network to gNB#1-DU through the RRC reconfiguration completion message (the third RRC message), and the DC subcarrier reporting result includes the location information of the third uplink DC subcarrier.

[0189] 7) After gNB#1-DU receives the RRC reconfiguration completion message containing the DC subcarrier reporting result information, it sends the RRC reconfiguration completion message to gNB#1-CU through the interface between gNB#1-DU and gNB#1-CU.

[0190] 8) After gNB#1-CU receives the uplink RRC forwarding message containing the RRC reconfiguration completion message sent by gNB#1-DU, it obtains the location information of the third uplink DC subcarrier and generates first carrier configuration information, wherein the first carrier configuration information includes: the location information of the third uplink DC subcarrier.

[0191] 9) gNB#1-CU sends the first carrier configuration information to gNB#1-DU via a user context modification request message. The user context modification request message includes one of the following: location information of the third uplink DC subcarrier.

[0192] 10) Since the user context modification request message includes the location information of the third uplink DC subcarrier, gNB#1-DU determines the physical layer scheduling configuration based on the information, including when gNB#1-DU triggers the UE to configure or deconfigure the uplink carrier or uplink BWP, determining whether to use the DC subcarrier or to use the subcarrier for sending SRS, DMRS and other signals based on the position of the UE's DC subcarrier when the state is configured according to the location information of the third uplink DC subcarrier.

[0193] Example 2: Mainly describes an NSA deployment scenario in which the LTE base station eNB#1 serves as an anchor base station (i.e., the second base station mentioned above), the NR gNB serves as an auxiliary base station and adopts a CU / DU separation architecture (i.e., the first base station mentioned above), the UE supports multi-carrier uplink transmission DC carrier reporting, and the UE is configured with two uplink carriers CC#1 and CC#2 by the base station NR gNB. The UE, in accordance with the network instructions, respectively feeds back the activation of BWP1 of CC#1 and BWP2 of CC#2, as well as the location information of the uplink DC subcarrier when only BWP#1 is activated, and indicates to the network through an RRC reconfiguration completion message whether the subcarriers determined by the NR gNB-DU (first base station separation entity) after deactivating BWP2 through MACCE can be applied to DMRS and CSI-RS subcarriers.

[0195] Support serving cell and BWP uplink transmission DC carrier reporting: yes;

[0198] 2) After LTE eNB#1 obtains the UE's wireless capabilities from the core network, it notifies the NR gNB of the UE's wireless capabilities through the X2 interface.

[0199] 3) When the NR gNB needs to configure or adjust the UE carrier or BWP configuration, the RRC reconfiguration request message for requesting the UE to perform the DC subcarrier reporting mode is determined based on the UE capabilities reported by the UE and the RRC version supported by the NRgNB-DU. The RRC reconfiguration request message is used to request the UE to feedback the first DC subcarrier configuration set it supports in the RRC reconfiguration completion message. Since the UE supports multi-carrier uplink transmission DC carrier reporting and the RRC version of the NR gNB-DU supports v17.3.0, the reporting mode is set to support multi-carrier uplink transmission DC carrier reporting. The reporting mode information carried in the primary cell set information in the RRC reconfiguration request message includes:

[0200] Multi-carrier uplink transmission DC carrier reporting: The specific information includes the intra-band uplink carrier aggregation configuration of CC#1 and CC#2. The intra-band uplink carrier aggregation configuration includes but is not limited to the following information:

[0202] · Two carrier aggregation configuration cases: the first case is {BWP#1 activated, BWP#2 activated}; the second case is {BWP#1 activated, CC#2 deactivated}.

[0203] 4) Since the UE is configured with dual connection and NR gNB is the secondary base station, NR gNB-CU needs to encapsulate the first RRC message in the form of an RRC container of the NR gNB standard and send it to eNB#1 through the X2 interface.

[0204] 5) eNB#1 generates a second RRC message based on the first RRC message from NR gNB-CU (first base station centralized entity) and sends it to the UE. When eNB#1 is used for air interface transmission, the second RRC message is encoded using eNB#1RRC ASN.1 and the first RRC message contained therein is still encoded using the RRC ASN.1 of the first-level base station and sent to the UE as a configuration request for the SCG cell.

[0205] 6) After the UE receives the second RRC message, when the reporting mode in the primary cell set information is "multi-carrier uplink transmission DC carrier reporting" information, the location information of the third uplink DC subcarrier of the uplink cells on all current SCGs is determined, and the location information of the third uplink DC subcarrier of each uplink cell includes:

[0208] · Upper limit of serving cell identification: CC#2;

[0209] A list of default DC subcarrier positions, each of which includes an uplink carrier / BWP configuration.

[0210] 7) The UE sends the DC subcarrier reporting result requested by the network to eNB#1 through an RRC reconfiguration completion message, where the DC subcarrier reporting result includes the location information of the third uplink DC subcarrier.

[0211] 8) eNB#1 forwards the DC subcarrier reporting result to the NR gNB-CU through the X2 interface. NR gNB-CU obtains the location information of the third uplink DC subcarrier and generates first carrier configuration information, the first carrier configuration information including: the location information of the third uplink DC subcarrier;

[0212] 9) The NR gNB-CU sends the first carrier configuration information to the NR gNB-DU via a user context modification request message. The user context modification request message includes one of the following: location information of the third uplink DC subcarrier.

[0213] 10) Since the user context modification request message includes the position information of the third uplink DC subcarrier, the NR gNB-DU determines the physical layer scheduling configuration based on the information, including when the NR gNB-DU triggers the UE to configure or deconfigure the uplink carrier or uplink BWP, determining whether to use the DC subcarrier or to use the subcarrier for sending SRS, DMRS and other signals based on the position of the UE's DC subcarrier when the state is configured according to the position information of the third uplink DC subcarrier.
