Embodiment Construction

[0048] The embodiments set forth below present information to enable those skilled in the art to practice the embodiments and illustrate the best mode of practicing the embodiments. After reading the following description in light of the accompanying drawing figures, those skilled in the art will understand the concepts of the disclosure and will recognize applications of these concepts not specifically addressed herein. It is to be understood that these concepts and applications fall within the scope of the disclosure and the appended claims. It is worth noting that the embodiments described herein focus on 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE), and thus often use 3GPP LTE terminology (e.g. User Equipment (UE), Primary Synchronization Signal (PSS) and Secondary Synchronization Signal (SSS)). However, the present disclosure is not limited to 3GPP LTE, but may be used in any suitable cellular communication network to improve synchronization signal...

Abstract

Systems and methods related to cell detection are disclosed. In some embodiments, systems and methods are disclosed for performing cell detection while suppressing interference from a wireless device's current serving cell or a previous serving cell based on whether the wireless device is approaching or leaving the current serving cell. . In this way, cell detection is improved in a manner that is particularly suitable for, for example, high-speed train scenarios, although the systems and methods disclosed herein are not limited thereto.

Description

technical field [0001] The present disclosure relates to cell detection in cellular communication networks. Background technique [0002] High-speed train scenarios are challenging for user equipment (UE) mobility functions because UEs may leave and enter cells quickly, so UEs must quickly detect suitable candidates for handover or cell reselection in order not to lose connection or Missed paging or paging signal. [0003] Current 3rd Generation Partnership Project (3GPP) standards already partially allow for UE speeds up to 300 kilometers per hour (300km / h), but only for the data demodulation part, not for cell detection. With the increased deployment of high-speed train lines, the increase in the number of UE users, and the increase in bandwidth usage per user, major operators are demanding improved UE performance and support for speeds exceeding 300km / h. [0004] In addition to the relatively short time to detect a suitable neighbor cell for handover or cell reselection...
