EIMTA CONFIGURATION FOR LTE IN UNLICENSED SPECTRUM

摘要

In the application of TDD and eIMTA to LTE in the unlicensed spectrum, various alterations may be needed to compensate for interference from and the behavior of RATs operating in this range of frequencies. Various UE and base station methods are presented, including modified TDD configurations and UE behaviors to advance operations on unlicensed spectrum. A method, an apparatus, and a computer-readable medium for wireless communication are provided whereby configuration information is conveyed to a UE for communicating on a carrier in the unlicensed spectrum. The configuration information indicates a subframe allocation for at least one frame on the unlicensed carrier. Other aspects are directed to the detection of the transmission, communication of new and modified eIMTA configuration transmissions, and mechanism and behaviors which address unreceived configuration information.

主权项

1. A method of wireless communication at a user equipment (UE), comprising:
attempting to receive first configuration information from a base station, the first configuration information indicating a first subframe allocation for at least one frame on a particular carrier of the base station; and receiving a downlink subframe from the base station during the at least one frame on the particular carrier in accordance with the first subframe allocation when the attempt to receive the first configuration information is successful, the downlink subframe being an initial subframe of a data transmission and subsequent to the start of the first subframe allocation.
