    Abstract: Methods, systems, and devices are described for data transmission using header compression techniques that may include dropping all of a portion of a payload for one or more Protocol Data Units (PDUs). A wireless communications device may determine that a robust header compression (RoHC) mode is in an initialization and refresh (IR) state, indicating a full Packet Data Convergence Protocol (PDCP) Protocol Data Unit (PDU), including complete header information, is to be transmitted. The wireless communications device may identify that a payload of at least part of a media frame is to be transmitted in the IR state, and drop at least part of the payload when a probability of segmenting the payload during transmission in the IR state exceeds a threshold.

    Abstract: Techniques are provided for controlling downlink data transfer during carrier aggregation. For example, a method may control a secondary component carrier downlink (DL) in a wireless communication network using carrier aggregation. The method may include detecting, by a mobile entity, an event indicating a resource constraint at the mobile entity related to a data transmission from a base station to the mobile entity on a secondary component carrier of a carrier aggregation enabled connection. The method may include, in response to detecting the event, controlling the data transmission by signaling a status of the secondary component carrier DL to the base station.

    Abstract: Methods, systems, and devices are described for improving discontinuous reception (DRX) power usage by dynamically updating (e.g., adjusting) a warmup period. A user equipment (UE) communicating with a wireless network may operate in DRX mode by periodically powering down radio components. For example, during a first DRX On Duration, the UE may estimate the variance in channel conditions. The UE may then update the baseband convergence portion of the warmup time prior to the upcoming DRX On Duration. The UE may reduce the baseband convergence period or increase the baseband convergence period based on a function of the channel variance. The UE may also maintain a table relating a set of channel variance values with a set of baseband convergence periods, and update the baseband convergence period based on the table.

    Abstract: Methods, systems, and devices are described for improving discontinuous reception (DRX) periods using enhanced physical HARQ indicator channel (PHICH) decoding. A user equipment (UE) may determine that an uplink (UL) retransmission (ReTx) is unnecessary based on the content of the original UL transmission. For example, the transmission may include media access control (MAC) layer padding rather than relevant application layer data. The UE may then identify a DRX sleep period that includes the subframe where the ReTx would take place. In some cases, the DRX sleep period may include a subframe where the UE would otherwise receive an acknowledgement message (AM) from a base station. The UE may then enter a DRX sleep state. In another example, the DRX sleep period is based on the content of a received AM. If the UE receives an ACK, the UL ReTx may be unnecessary.

    Abstract translation: 描述了使用增强的物理HARQ指示符信道（PHICH）解码来改善不连续接收（DRX）周期的方法，系统和设备。 用户设备（UE）可以基于原始UL传输的内容来确定不需要上行链路（UL）重传（ReTx）。 例如，传输可以包括媒体访问控制（MAC）层填充而不是相关的应用层数据。 然后，UE可以识别包括将发生ReTx的子帧的DRX休眠周期。 在一些情况下，DRX休眠期可以包括UE将否则从基站接收确认消息（AM）的子帧。 然后，UE可以进入DRX睡眠状态。 在另一示例中，DRX休眠期基于所接收的AM的内容。 如果UE接收到ACK，那么UL ReTx可能是不必要的。
