Abstract

In an environment following TDD subframe reconfiguration from an evolved Node B (eNB), a transmission of control data by a user equipment (UE) may cause a collision with a scheduled transmission of the control data. In one example, the UE may modify the period, content, priority, or other aspects of channel state information (CSI) or sounding reference signal (SRS) to resolve any conflicts caused by TDD subframe reconfiguration and ensure that the CSI or SRS transmission. In another example, the UE may detect hybrid automatic repeat request (HARQ) collisions caused by TDD subframe reconfiguration. In such an example, the UE may determine and apply the HARQ soft buffer size for the HARQ process, or determine and apply the codebook size for the HARQ process in carrier aggregation, to resolve such HARQ collisions.

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Application Serial No. 61 / 639,737, filed April 27, 2012, entitled "METHODS AND APPARATUS FORTDD RECONFIGURATION" and filed April 25, 2013, entitled "METHODS AND APPARATUS FOR TDD RECONFIGURATION," US Application No. 13 / 870,927, which is hereby expressly incorporated by reference in its entirety. technical field [0003] The present disclosure relates generally to communication systems, and more particularly to providing adaptive time division duplex resource allocation. Background technique [0004] Wireless communication systems are widely deployed to provide various types of communication content such as, for example, voice, data, and so on. A typical wireless communication system may be a multiple-access system capable of supporting communication with multiple users by sharing available system resources (eg, bandwidth, transmit power, ...). Examples of such m...
