Abstract

A data structure for managing user equipment communications in a wireless communication system is presented. In some examples, the data structure may include one or more resource element blocks into which a frequency bandwidth of a downlink channel is divided within a symbol that defines a transmission time interval in a downlink subframe. Furthermore, the data structure may include a control region and a data region within at least one resource element block of the one or more resource element blocks. Additionally, the data structure may include a downlink resource grant, located within the control region, for a user equipment served by the downlink channel. In an additional aspect, a network entity and method for generating the example data structure are provided.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to Provisional Application No. 62 / 053,695, filed September 22, 2014, entitled "ULTRA-LOW LATENCY LTE DOWNLINKFRAME STRUCTURE," and filed September 16, 2015, entitled "ULTRA- LOW LATENCY LTE DOWNLINK FRAME STRUCTURE," the priority of U.S. Patent Application No. 14 / 856,242, which is hereby expressly incorporated by reference in its entirety. Background technique [0003] The present disclosure generally relates to a communication system, and in particular, to a downlink frame structure and a downlink transmission method for managing communication with a user equipment in a wireless communication system. [0004] Wireless communication systems are widely deployed to provide various types of telecommunication services, such as telephony, video, data, messaging, and broadcast, among others. A typical wireless communication system may employ multiple access techniques capable of supporting com...
