Embodiment Construction

[0056] A detailed description of example embodiments will now be described with reference to various drawings. Although this description provides detailed examples of possible implementations, it should be understood that the detailed description is illustrative and does not limit the scope of the invention.

[0057] Disclosed herein are systems and / or methods that use devices such as UE and / or low-cost machine type communication (MTC) devices in wireless communication to support reduced channel bandwidth. To support this reduced channel bandwidth, as described herein, in-band assignment of downlink (DL) and / or uplink (UL) transmission resources for UEs or MTC devices may be provided and / or used , PCFICH and / or PDCCH through zero-power CSI-RS in the data domain, PCFICH, PHICH, and / or PDCCH transmission in the control domain, multiplexing control and / or data transmission, and / or network configuration. In addition, as described herein, it is possible to provide and / or use DL recei...

Abstract

Systems and/or methods for supporting communications at a reduced bandwidth with a full bandwidth network such as a long-term evolution (LTE) network may be disclosed. For example, inband assignments such as downlink assignments and/or uplink grants may be provided and/or received and transmissions may be monitored and/or decoded based on the inband assignment. Additionally, information (e.g. a definition or configuration) associated with an ePDCCH may be provided and/or received and ePDCCH resources may be monitored and/or decoded based on such information. An indication for support of a reduced bandwidth by the full bandwidth network may also be provided and/or received and control channels in the reduced or narrow bandwidth may be monitored and/or decoded based on the indication. A PRACH preamble and/or a multi-type sub frame definition may also be provided and/or used for support of such a reduced bandwidth.

Description

Background technique [0001] As wireless communication systems such as LTE systems mature and their network deployments develop, network operators will like to reduce the cost of communication networks and / or communication network maintenance. A technique for reducing network costs can reduce the channel bandwidth and data rate used to communicate with devices on the network. For example, a part of the channel bandwidth instead of the entire channel bandwidth may be supported by devices in the network and / or by the network itself when communicating with such devices. Unfortunately, the current wireless communication system does not support providing information such as channel information including control channel information, uplink information, downlink information, etc. on a reduced channel bandwidth. Summary of the invention [0002] Systems and / or methods can be provided to support devices such as UEs (for example, including low-LTE UE-type devices) and / or low-cost machine t...
