Background

Aspects of the present disclosure relate generally to wireless communication systems, and more particularly, to using a Cyclic Prefix (CP) in wireless communication.

Wireless communication systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems may be multiple-access systems capable of supporting communication with multiple users by sharing the available system resources (e.g., time, frequency, and power). Examples of such multiple-access systems include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Access (FDMA) systems, and Orthogonal Frequency Division Multiple Access (OFDMA) systems, as well as single carrier frequency division multiple access (SC-FDMA) systems.

These multiple access techniques have been adopted in various telecommunications standards to provide a common protocol that enables different wireless devices to communicate on a city, country, region, and even global level. For example, fifth generation (5G) wireless communication technologies, which may be referred to as 5G new radios (5G NRs), are designed to extend and support diverse usage scenarios and applications relative to current mobile network generation. In one aspect, the 5G communication technology may include: enhanced mobile broadband for human-centric use cases for accessing multimedia content, services and data; ultra-reliable low latency communication (URLLC) with certain specifications regarding latency and reliability; and large-scale machine-type communications, which may allow for a very large number of connected devices and the transmission of relatively small amounts of non-delay sensitive information. However, as the demand for mobile broadband access continues to grow, further improvements in 5G communication technologies and beyond 5G technologies may be desirable.
