Abstract

Methods and apparatuses for controlling resource bundling in a wireless communication system, the method including the steps of selecting a bundle size; bundling, according to the bundle size, resource element groups (REGs) of a first control channel element (CCE) into one or more first REG bundles; and mapping the one or more first REG bundles to physical resource elements for control channel transmission.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority to U.S. Provisional Application No. 62 / 500,156, filed May 2, 2017, the entire contents of which are incorporated herein by reference. technical field [0003] The present application relates to communication systems, and more particularly, the present application relates to methods and apparatuses for controlling resource bundling and mapping in wireless communication systems. Background technique [0004] In a Long Term Evolution (LTE) system, a control region spanning multiple Orthogonal Frequency Division Multiplexing (OFDM) symbols and multiple frequency subcarriers may be allocated for transmission of a Physical Downlink Control Channel (PDCCH). A resource element is defined as the smallest resource structure covering one subcarrier on one OFDM symbol. Multiple resource particles form a resource particle group (REG). According to the size of the payload and the cha...
