Allocation of physical channel resources hybrid ARQ indicator (PHICH)

摘要

A method (600) for wireless communication, comprising: determining (602) that a first component carrier, CC, time division duplexed, TDD, with a first uplink subframe configuration, UL / downlink, DL, it is programmed with cross carrier by means of a second CC with a second UL / DL subframe configuration; determine (604) a timing of the hybrid automatic repeat request, HARQ, of the uplink transmissions in the first CC; determining (606) the availability of resources of the physical indicator channel of HARQ, PHICH, in a subframe in the second CC for uplink transmissions in the first CC based on the determined HARQ timing of uplink transmissions in the first CC; and perform (608) or suspend an uplink transmission in a subframe in the first CC based on the determination of PHICH resource availability
