example 1

[0150] Example 1: A method comprising: transmitting data of a first type during a time interval, the time interval having N OFDM symbols; transmitting data of a second type during the time interval, the data of the second type having The duration of kN / k possible OFDM symbol positions within the time interval.

example 2

[0151] Example 2: The method of example 1, wherein the first type of data is latency tolerant data and the second type of data is low latency data.

example 3

[0152] Example 3: The method of example 1, wherein transmitting data of the second type comprises transmitting a first time slot of k OFDM symbols, and wherein the method further comprises transmitting a second time slot of k OFDM symbols, the second A two-slot also starts at one of m>N / k possible OFDM symbol positions within the time interval.

Abstract

Systems and methods are disclosed in which the start time of a downlink transmission to a user equipment (UE) is more flexible. For example, instead of beginning at predetermined starting points in aframe or subframe, a downlink transmission may instead possibly begin every Chi OFDM symbols, where Chi may be as small as one OFDM symbol.

Description

[0001] Related Application Cross Reference [0002] This application claims priority to U.S. Provisional Patent Application No. 62 / 398,320, filed September 22, 2016, entitled "Flexible Slot Architecture for Low-Latency Communications," and filed September 2017 Priority to US Patent Application Serial No. 15 / 709,018, filed on the 19th, the contents of both are hereby incorporated by reference in their entirety. technical field [0003] The present application relates to wireless communication, and in particular to low-latency communication. Background technique [0004] In some wireless communication systems, user equipment (UE) communicates wirelessly with one or more base stations. Wireless communication may be performed by sending orthogonal frequency-division multiplexing (OFDM) symbols, which may be based on, for example, orthogonal frequency-division multiplexing (orthogonal frequency-division multiplexing) multiple access (OFDMA) or a non-orthogonal multiple access (...
