Abstract: Certain embodiments relate to wireless communication systems, such as long term evolution advanced (LTE-A), which may be part of third generation partnership project (3GPP) LTE release 12 (Rel-12). More specifically, certain embodiments may provide an arrangement related to new carrier type for time division long term evolution (TD-LTE), which may also be related to Enhanced Interference Management and Traffic Adaptation. According to certain embodiments, a method can include determining that a split configuration is to be followed, in which at least one system information block configured up-link subframe is reconfigured as a new carrier type downlink subframe, whereas at least one other system information block configured subframe is as indicated by system information block configuration. The method can also include applying the determined split configuration to communications with an access point.

Abstract: An example technique may include transmitting, by a base station via a component carrier in a licensed band, control information including a resource allocation that identifies time-frequency resources for periodical transmission opportunities to be used for the conditional transmission of discovery reference signals via a secondary component carrier in an unlicensed band, determining, prior to each transmission opportunity, whether the secondary component carrier in the unlicensed band is unoccupied, and transmitting, if the secondary component carrier in the unlicensed band is unoccupied, the discovery reference signals via the secondary component carrier in the unlicensed band using the identified time-frequency resources to one or more user devices.

Abstract: Feedback determined for a plurality of subframes within a time window in a time division duplex system is bundled into at least two sets of feedback information based on differently timed bundling windows defined based on subframe types. When feedback associated with the plurality of subframes is received, possible errors in the subframes is determined based on the at least two sets of feedback information.

Abstract: Systems, methods, apparatuses, and computer program products for signal block mapping are provided. One method includes configuring, by a network node (e.g., base station or eNB), a group of discovery signaling blocks. The method may then include mapping the discovery signaling blocks of the group onto a subframe structure, including the group information into each of the discovery signaling blocks, and transmitting the discovery signaling blocks in the subframe structure.
