Abstract: Mechanisms are disclosed for improved transmission of uplink control information by a user equipment (UE) that is link budget limited. In one embodiment, the UE transmits a message to the base station indicating that the UE is link budget limited. In response to the message, the base station sends an uplink grant to the UE, enabling the UE to transmit uplink control information on the physical uplink shared channel (PUSCH) instead of on the Physical Uplink Control Channel (PUCCH). In another embodiment, the base station sends an uplink grant to a link-budget-limited UE each time downlink traffic is transmitted to the UE, enabling the UE to send ACK/NACK feedback on the PUSCH instead of the PUCCH. In another embodiment, the UE transmits a scheduling request (SR) to the base station as part of a random access procedure, enabling the SR to be transmitted on the PUSCH instead of the PUCCH.

Abstract: For paging user devices that are link budget limited (LBL), a base station transmits a special ID that is used by said devices to identify a paging frame and/or a paging occasion. When transmitting a paging message for an LBL device, the base station may use: (a) larger aggregation and larger CFI (than conventionally allowed) and (b) a larger number of resource blocks (than conventionally allowed) for paging payload. If paging messages for LBL devices saturate the paging frame capacity, the base station may allocate a plurality of special IDs. If paging messages for LBL devices and/or other data transfers saturate network capacity, at least a subset of the LBL devices may be directed to enter a connected-state discontinuous reception (DRX) mode, wherein those devices will remain in connected mode and periodically check for resource allocations. Paging payload information may be repeatedly transmitted in successive subframes, to support soft combining.

Abstract translation: 对于作为链路预算限制（LBL）的寻呼用户设备，基站发送由所述设备使用的专用ID，以识别寻呼帧和/或寻呼时机。 当发送用于LBL设备的寻呼消息时，基站可以使用：（a）更大的聚合和更大的CFI（比常规允许的）和（b）用于寻呼有效载荷的更多数量的资源块（比常规允许的）。 如果LBL设备的寻呼消息使寻呼帧容量饱和，则基站可以分配多个特殊ID。 如果用于LBL设备的寻呼消息和/或其他数据传输饱和网络容量，LBL设备的至少一个子集可以被引导进入连接状态不连续接收（DRX）模式，其中那些设备将保持连接模式并且周期性地 检查资源分配。 分页有效载荷信息可以在连续的子帧中重复发送，以支持软组合。

Abstract: Mobile devices, base stations, and/or relay stations may implement a method for an improved and reliable automatic repeat request feedback indication. A mobile device (UE) may establish communication within a wireless network, and indicate to the network that the UE is a special type device, e.g. a constrained device. The network (base station) may then not send an indication on a physical indicator channel to the UE when certain conditions are met, and instead, the mobile device may interpret control information received from the network on a physical control channel as a negative acknowledgment indication corresponding to an automatic repeat request from the network. The UE may then perform a retransmission according to the interpreted control information. A new control information format may be used to further define how the network and UE implement the automatic repeat request process, to reduce the total number of bits required in the control information.

Abstract: Apparatus and methods for time division multiplexing of radio frequency channels in unlicensed radio frequency bands by a wireless device in communication with a cellular wireless network are disclosed. The wireless device obtains, from an eNodeB, a configuration for carrier aggregation using a primary component carrier (PCC) in a licensed radio frequency band and at least one secondary component carrier (SCC) in an unlicensed radio frequency band. The configuration information specifies an “on” time period and an “off” time period for a repetitive time division cycle to use the at least one SCC in the unlicensed radio frequency band. During an “on” time period, the wireless device can transmit or receive using the PCC and the at least one SCC, as scheduled by the eNodeB. During an “off” time period, the wireless device can transmit or receive using the PCC and not using the at least one SCC.
