Abstract: Uplink synchronization may be achieved without adjusting for timing advance by using longer/larger cyclic prefix durations to compensate for differences in propagation delays, including the cell round-trip delays and environment based multipath delays. In this way, timing advance reference signaling may be omitted from the uplink transmissions. The cyclic prefix duration may be determined based on a characteristic of a base station's coverage area, such as a coverage area size or coverage area type. For example, a longer cyclic prefix length may be used when a base station has a larger coverage area than when the base station has a smaller coverage area. As another example, a different cyclic prefix length may be used for different coverage types. The method provided in this embodiment improves the capabilities of automatic driving and ADAS of electric vehicles. The method can be applied to vehicle networking, such as V2X, LTE-V, V2X, etc.

Abstract: A random access (RA) scheme exhibiting a non-isometric frame duration and a low latency. The RA and data messages have a duration with a different time unit and the time slot of the RA message is much shorter than the duration of one data frame. A specific signature, which is designed to be robust against the collisions, is transmitted during the RA request, the signature being either a unique sequence or a compressed signature. The user equipment device transmits the data message immediately after receiving its resource through a frame structure showing a time misalignment between adjacent data frames located in different or identical frequency sub-bands. A frequency guard band is inserted between its resource and an adjacent resource assigned to another user equipment device, the frequency guard band having an adaptive size according to the level of time misalignment and its impact on the distortion.
