Abstract: Certain aspects of the present disclosure generally relate to wireless communications and, more specifically, to power savings based on distributed enhanced machine type communication (eMTC) functions, for example, between an applications processor and a modem of an eMTC device. An example method generally includes entering a power saving mode (PSM), wherein entering the PSM includes performing a first power collapse of an applications processor of the wireless node and a modem of the wireless node into a low power state; exiting the PSM at expiry of a wake-up timer, wherein exiting the PSM includes waking up the applications processor and the modem from the low power state to an active power state; and in response to exiting the PSM, performing a second power collapse of the applications processor into the low power state while the modem operates in the active power state.

Abstract: Aspects of resolving conflicting configuration parameters during wireless communication include triggering reselection to a new cell from a current cell and determining that a user equipment (UE) is configured in a forward access channel (FACH) state and is waiting for a Layer 2 Acknowledgement (L2 ACK) message from a network entity when reselection to the new cell is triggered. Further, the aspects include performing a collision resolution procedure in response to the determination that the UE is configured in the FACH state and is waiting for the L2 ACK message. In some aspects, the collision resolution procedure establishes which one of a plurality of information elements (IEs) to choose for a reconfiguration procedure.

Abstract translation: 在无线通信期间解决冲突配置参数的方面包括从当前小区触发对新小区的重新选择，并确定用户设备（UE）被配置在前向接入信道（FACH）状态中并且正在等待第2层确认（L2 ACK）来自网络实体的消息被触发。 此外，这些方面包括响应于UE被配置在FACH状态并正在等待L2 ACK消息的确定来执行冲突解决过程。 在一些方面，冲突解决过程确定为重新配置过程选择多个信息元素（IE）中的哪一个。

Abstract: The disclosure provides for a user equipment (UE) handling radio link control (RLC) reset in wireless communications. Various techniques are described wherein RLC reset procedures are associated with various triggering conditions and predetermined time periods at RLC. Delays for initiation and execution of the RLC reset procedures are also described. In an aspect, the UE determines that at least one data unit to be received over a first logical channel is yet to be received by the UE and that there is data traffic over a second logical channel with higher priority than the first logical channel. In another aspect, the UE delays initiation of an RLC reset on a condition that the UE determines that at least one data unit is yet to be received over the first logical channel and that there is data traffic over the second logical channel.

Abstract: Techniques for managing cell update messages are described here. An information element (IE) that indicates the security status of a user equipment (UE) may be included in the cell update message when a cell update procedure is triggered during an ongoing security mode procedure. To ensure the size of the cell update message is equal to or smaller than the transport format size, other IEs may be omitted from the cell update message if the security mode procedure is in progress. Alternatively, if the security mode procedure is not in progress, there may not be a need to update the security status of the UE and, thus, the IE that indicates the security status may be omitted from the cell update message to reduce the size of the cell update message.

Abstract: Disclosed are systems and methods for continuous inter-frequency measurement reconfigurations in a DC-HSUPA User Equipment (UE). In one aspect, the system may configure the UE to perform intra-frequency measurements on a frequency f1 and inter-frequency measurements on a frequency f2 in a dual carrier (DC) downlink (DL) mode and a single carrier (SC) uplink (UL) mode. The system may then reconfigure the UE to operate in a DC UL mode and continuing to perform inter-frequency measurements on the frequency f2 in the DC UL mode. The system may then reconfigure the UE to operate in the SC UL mode and continuing to perform inter-frequency measurements on frequency f2 in the SC UL mode.

Abstract: The present disclosure presents a method and an apparatus for improving power performance at a user equipment (UE). For example, the method may include aggregating data at the UE for transmitting on a uplink (UL) from the UE to a base station communicating with the UE until a data aggregation condition is satisfied, determining when the data aggregation condition is satisfied at the UE, wherein the data aggregation condition includes at least a buffer occupancy condition or a delay transmission timer, and requesting resources from the base station for transmitting the data on the UL in response to determining that the data aggregation condition is satisfied. As such, improved performance at a UE is achieved.
