Abstract: Methods and apparatus are described herein for synchronizing timing when using a secondary component carrier (SCC) in a carrier aggregated wireless network. A user equipment (UE) may determine that it is out of synchronization with respect to an SCC used to communicate with a network element. The UE may inform the network element of the out of synchronization status, and may perform a random access procedure to synchronize the timing.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives extended bandwidth information indicating availability of an extended bandwidth. The extended bandwidth includes a base carrier and an extension carrier within a legacy guard band of the base carrier. The apparatus receives data on a downlink in the extension carrier based on the extended bandwidth information.

Abstract: Techniques for sending control information to support operation on multiple component carriers (CCs) are disclosed. A user equipment (UE) may be configured with multiple CCs for carrier aggregation. The multiple CCs may be associated with different uplink-downlink configurations and may have different downlink subframes and uplink subframes. In one aspect, uplink control information (UCI) for a secondary CC (SCC) may be sent on a primary CC (PCC) based on a UCI transmission timeline for the PCC (and not based on a UCI transmission timeline for the SCC). For example, a downlink grant for the SCC may be sent based on a downlink grant transmission timeline for the PCC. In another aspect, uplink grants for an SCC may be sent on the PCC based on an uplink grant transmission timeline for the PCC (and not based on an uplink grant transmission timeline for the SCC).

Abstract translation: 公开了用于发送控制信息以支持多分量载波（CC）上的操作的技术。 用户设备（UE）可以配置有多个用于载波聚合的CC。 多个CC可以与不同的上行链路 - 下行链路配置相关联，并且可以具有不同的下行链路子帧和上行链路子帧。 在一个方面，可以基于用于PCC的UCI传输时间线（而不是基于SCC的UCI传输时间线）在主CC（PCC）上发送用于辅助CC（SCC）的上行链路控制信息（UCI）。 例如，可以基于PCC的下行链路许可传输时间线来发送用于SCC的下行链路许可。 在另一方面，可以基于PCC的上行链路授权传输时间线（而不是基于SCC的上行链路许可传输时间线）在PCC上发送用于SCC的上行链路许可。

Abstract: Methods, apparatuses, and computer program products are disclosed for facilitating indicating and detecting control region sizes. A multi-carrier communication between a wireless terminal and a base station is facilitated by a first carrier having a first control region size and a second carrier having a second control region size. Embodiments are disclosed in which control region sizes are ascertained from a control signal, wherein the control is generated by either scrambling an aspect of the control signal based on the second control region size, or relating the second control region size with the first control region size. Other disclosed embodiments for ascertaining control region sizes include a reverse interleaver embodiment, wherein a set of modulation symbols is mapped beginning from a last data symbol and ending with a first available data symbol.

Abstract: A method, a computer program product, and an apparatus for determining retransmission feedback resources are provided. An apparatus receives a downlink resource assignment over a control channel and obtains an offset related to a region for retransmission feedback resources. The offset is determined based on a type of the control channel. The apparatus determines resources for communicating retransmission feedback for communications received over the downlink resource assignment based on an index of a resource related to the downlink resource assignment and the offset. The apparatus transmits retransmission feedback for the communications over the resources.
