20130195070 | TIME AND FREQUENCY SYNCHRONIZATION FOR LTE-ADVANCED NEW CARRIER TYPE - A particular kind of component carrier that may be used as a secondary cell in an LTE system is a new type carrier that has reduced or eliminated legacy control signaling such as the omission of CRSs. Alternative techniques are described for performing timing and frequency synchronization in the downlink between an eNB and a UE when CRSs are not present in a component carrier. These techniques involve using either channel state information reference signals or UE-specific reference signals. | 08-01-2013 |
20130265972 | Updating Channel State Information in a Wireless Network - A system for updating channel state information may include a base station wirelessly sending a reference signal to a user device. The bases station may receive channel state information based on the reference signal. Then, the bases station may determine a number of transport blocks to enable, a number of layers to use, and an order of modulation for each transport block based on the channel state information. The bases station may then receive subsequent channel state information from the user device using the determined parameters. | 10-10-2013 |
20130265975 | Transmitting Uplink Control Information - In accordance with some embodiments, uplink control information, including a channel quality index, may be transmitted using at least two layers. As a result, more information can be provided for use in situations, such as those involving carrier aggregation, where information for a large number of component carriers must all be provided on one primary component carrier. | 10-10-2013 |
20130301491 | SCHEDULING SYNCHRONIZATION SIGNALS IN A NEW CARRIER TYPE - Technology is discussed for supporting the incorporation of a Primary Synchronization Signal (PSS) and/or a Secondary Synchronization Signal (SSS) within in a New Carrier Type (NCT) for a Component Carrier (CC). Guidelines for incorporating the PSS and/or the SSS in the NCT are discovered, together with potential collisions with other signals that can be avoided for various scenarios. In some examples, various guidelines and potential collisions discovered herein, for various scenarios, inform approaches to incorporating the PSS and/or the SSS based on the positioning of the PSS and/or the SSS. In other examples, other signals, such as DeModulation Reference Symbols (DMRS) are reconfigured to allow incorporation of the PSS and the SSS. | 11-14-2013 |

An indicator field is used to identify whether a reduced overhead DRMS pattern is being transmitted. If appropriate, the reduced overhead DRMS pattern is generated and transmitted by the small cell station and received and used by the user equipment as indicated by the indicator field. | 10-09-2014 |
20150009870 | MAPPING SPECIAL SUBFRAMES IN A WIRELESS COMMUNICATION NETWORK - Methods, apparatuses, and systems are described related to mapping special subframes in a wireless communication network. In embodiments, an eNB may assign demodulation reference signals (DM-RSs) and/or cell-specific reference signals (CRSs) to a downlink pilot time slot (DwPTS) of a special subframe responsive to a determined configuration of the special subframe. In embodiments, an eNB may bundle the DwPTS or an uplink pilot time slot (UpPTS) of the special subframe with another subframe for scheduling. In embodiments, a UE may estimate a channel associated with the special subframe based on DM-RSs and/or CRSs transmitted in another subframe. In embodiments, an eNB may exclude the DwPTS from scheduling for certain special subframe configurations if a new carrier type (NCT) is used. In embodiments, an eNB may exclude certain special subframe configurations from use for NCT communications. Other embodiments may be described and claimed. | 01-08-2015 |
