    Abstract: Described are methods and devices for enabling D2D communications with signal structures that require minimal changes to the current LTE architecture. In the embodiments described, the eNB grants resources to UEs for D2D communication and either initiates or permits a pair of UEs to establish a D2D link. Certain embodiments are designed to minimize changes to the current LTE control signaling structure by having the control signaling always come from the eNB as in a normal cellular link so that the transmitting UE transmits over a data channel (e.g., PUSCH/PDSCH) that the receiving UE is able to decode.

    Abstract: Systems and methods to encode and/or decode structured super-position coding to enhance control channel capacity are disclosed herein. User equipment (UE) may be configured to communicatively couple to an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) Node B (eNB). A first UE and a second UE may be coupled to the eNB. Basic PDCCH may be sent to the second UE, and extra PDCCH may be sent to the first UE on the same time-frequency resource. The second UE may be able to decode the basic PDCCH as it normally does. The first UE may be able to decode the basic PDCCH for the second UE, cancel the basic PDCCH from the signal, and decode the extra PDCCH. The extra PDCCH may be restricted to certain positions relative to the basic PDCCH to simplify searching by the first UE.

    Abstract: Technology for blind decoding downlink control information (DCI) from an enhanced physical downlink control channel (EPDCCH) is disclosed. In an example, a user equipment (UE) can include a processor configured to: Recursively attempt to decode the DCI from enhanced control channel elements (ECCE) of the EPDCCH from physical resource block (PRB) region candidates in a PRB set using a selected set of enhanced resource element group (EREG) index maps for the ECCE until the DCI is successfully decoded; and decode the DCI with an EREG index map associated with a same aggregation level used to encode the DCI. Each EREG index map can be configured for a different aggregation level (AL).

    Abstract: A system and method utilizes a selected PRB configuration for a new carrier type for a 3GPP-type wireless network. A downlink signal is received that comprises a demodulation reference signal pattern in at least one predetermined subframe of the downlink signal. The subframe comprises a first predetermined number of the plurality of orthogonal frequency division multiplex (OFDM) symbols comprising synchronization signals for a legacy version of the downlink signal and the demodulation reference signal pattern comprising a second predetermined number of OFDM symbols that are different from the first predetermined number of the plurality of OFDM symbols. After receiving the downlink signal, the demodulation reference signal pattern in the downlink signal is demodulated.
