Interaction method, base station, terminal and electronic device of asymmetric bandwidth configuration

[0001] Cross-reference to related applications

[0002] The present disclosure is based on and claims priority to the application with CN application number 202411087865.6 and filing date of August 8, 2024, the disclosure of which is hereby incorporated by reference in its entirety into the present disclosure. TECHNICAL FIELD

[0003] The present disclosure relates to the field of wireless communication, in particular, to an interaction method of asymmetric bandwidth configuration, a base station, a terminal and an electronic device. BACKGROUND

[0004] A NR (New Radio) synchronization signal block (SSB, Synchronization Signal Block) includes a PSS (Primary Synchronization Signal), a SSS (Secondary Synchronization Signal) and a PBCH (Physical Broadcast Channel). One SSB is composed of PSS, SSS and PBCH. PSS, SSS and PBCH adopt TDM (Time Division Multiplexing) manner: one SSB occupies 4 OFDM (Orthogonal Frequency Division Multiplexing) symbols, PSS and SSS each occupy one symbol, and PBCH occupies two symbols, the order is PSS-PBCH-SSS-PBCH. The benefit of placing SSS in the middle of PBCH symbol is that SSS can be used to assist PBCH demodulation. The bandwidth of one SSB is 20 PRBs (Physical Resource Blocks), the bandwidth of PSS and SSS is 12 PRBs, the bandwidth of PBCH is 20 PRBs, the center frequency of PSS / SSS and the center frequency of PBCH are aligned. In addition, PBCH also occupies part of the PRBs of the OFDM symbol where SSS is located, PSS, SSS and PBCH in each SSB use the same subcarrier spacing.

[0005] GSCN(Global Synchronization Channel Number): When the terminal just powers on and searches for a cell, it can only detect the SSB signal according to the operator and the frequency band supported by the terminal to perform downlink time-frequency synchronization. Due to the small granularity of the global frequency grid, the value range of the NR-ARFCN is large. If blind detection is directly performed according to the global frequency grid, the synchronization delay will be large. In order to effectively reduce the synchronization delay of this process, 3GPP specially defines a synchronization grid, and limits the search range through the global synchronization channel number (GSCN).

[0006] In order to optimize the spectrum utilization, in NR R15, asymmetric bandwidth UL / DL is introduced for some NR bands, that is, the channel bandwidth of the UE (User Equipment) in a specific band can be asymmetric in the downlink and uplink. FDD (Frequency Division Duplexing) asymmetric band includes n5 / 8 / 25, etc., and TDD (Time Division Duplexing) only has one n50, and the supported bandwidth of the uplink and downlink is also unique.

[0007] In some embodiments, n25, only one asymmetric channel bandwidth combination Set 0 (asymmetric channel Bandwidth Combination Set 0), the uplink bandwidth is 40MHz, and the downlink bandwidth is 45MHz. As long as the terminal supports the asymmetric channel bandwidth combination Set ID (asymmetric channel Bandwidth Combination Set ID), the network side can configure the specific bandwidth for the UE according to the uplink and downlink supported bandwidth information in Set ID.

[0008] In order to improve the service performance, 3GPP introduces a transmission bandwidth less than 5MHz in Rel-18, such as band n28, whose uplink channel bandwidth is 3MHz and downlink channel bandwidth is 5MHz. The unique asymmetric channel bandwidth combination is Set 1, that is, the Set ID in the asymmetric channel Bandwidth Combination Set ID is 1. According to TS38.331 and TS38.101, it can be known that the less than 5MHz dedicated channel includes 12PRB, 15PRB and 20PRB transmission bandwidth. SUMMARY

[0065] In order to enable personnel in the technical field to better understand the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in combination with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative labor should fall within the scope of protection of the present disclosure.

[0066] It should be noted that the terms "first", "second", and the like in the specification and claims of the present disclosure and the above-described drawings are used to distinguish similar objects, and do not necessarily have to be used to describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device including a series of steps or units does not have to be limited to only those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products, or devices.

[0067] The current standard and protocol also have the following problems:

[0068] (1) The current standard does not support the first base station to send its asymmetric channel bandwidth related configuration to the second base station, and the second base station cannot know that the first base station adopts the asymmetric channel bandwidth configuration, but defaults that the first base station adopts the symmetric channel bandwidth, which may cause the terminal to receive the command to switch to the second base station in the case of not supporting the asymmetric channel bandwidth, thereby causing the terminal switching failure and reducing the terminal mobility performance;

[0069] (2) The current standard does not support the first base station to send its configuration related to the bandwidth less than 5MHz, such as 12PRB, 15PRB, 20PRB transmission bandwidth configuration to the second base station, thereby causing the second base station to be unable to determine whether it can access the first base station according to the terminal capability, and unable to generate reasonable neighbor cell measurement and handover parameters for the connected state terminal;

[0070] (3) The current standard first base station cannot send the asymmetric channel bandwidth, bandwidth less than 5MHz related configuration to the second base station, and the second base station cannot configure reasonable neighbor cell measurement parameters or handover command or cell reselection command for the terminal according to the terminal capability and the first base station related configuration, which causes the terminal to be unable to avoid unreasonable measurement and unreasonable cell handover, cell reselection command, etc.

[0071] Therefore, the current standard cannot well support the terminal access to the asymmetric cell characteristics, and therefore, in order to enhance the existing protocol to meet the compatibility requirements of the conventional terminal, and to support the terminal mobility problem introduced after the asymmetric bandwidth, the embodiment of the disclosure provides an interaction method of asymmetric bandwidth configuration, based on the method, the first base station sends the configuration information of the asymmetric bandwidth to the second base station through the first request message, in addition, the second base station also sends the configuration information of the asymmetric bandwidth to the first base station through the first response message, then, the second base station configures reasonable neighbor cell measurement parameters for the terminal according to the support capability of the terminal for the asymmetric bandwidth, and assists the terminal to make more reasonable measurement, wherein, for the terminal supporting the asymmetric bandwidth configuration, it can be instructed to access the second base station cell supporting the asymmetric bandwidth configuration. The method can run in the computer terminal shown in FIG. 1, and the computer terminal is explained and described below.

[0072] According to the current TS38.423 protocol, the inter-base station does not support the interaction of less than 5MHz transmission bandwidth and TDD asymmetric bandwidth related information through the Xn interface, which increases the terminal mobility failure rate.

[0073] At present, there is no effective solution to the above problems.

[0074] The embodiment of the disclosure provides an interaction method of asymmetric bandwidth configuration, a base station, a terminal and an electronic device, to at least solve the technical problem that the current standard cannot well support the terminal access to the asymmetric cell characteristics.
