Abstract: A station (STA) can receive messages (e.g., beacon frames) at a regular interval, and perform measurements on the received messages. The STA maintains a running average of recent measurement values, and updates the running average after each new measurement interval. At some measurement opportunities, the expected messages cannot be received by the STA, and so the STA cannot perform a measurement; when this occurs, the STA can choose substitute values to use for the missed measurements when next calculating the running average. As one example, the STA can substitute the value for a previously-performed measurement for the missed measurements. As another example, the STA can substitute a predetermined low value for the missed measurements. Based on the value of the running average at a given point in time, the STA can take actions such as initiating a roaming scan or switching to a different wireless interface.

Abstract: A method for controlling transmission power in accordance with a total transmission power limit in a multi-radio wireless communication device including a master radio and a slave radio is provided. The method can include the wireless communication device determining, at the master radio, a transmission power of the master radio. The method can further include the wireless communication device providing information indicative of the transmission power of the master radio from the master radio to the slave radio. The method can additionally include determining, at the slave radio, an allowable transmission power for the slave radio. A sum of the allowable transmission power and the transmission power of the master radio may not exceed the total transmission power limit.

Abstract: This disclosure relates to reducing power consumption for cellular communication based on transport block size in combination with channel condition measurements for applications with certain application characteristics. In one embodiment, a transport block size for use for uplink communication with a base station by a wireless device may be selected. The transport block size may provide more robust communication characteristics than required for current channel conditions. The transport block size may be selected based on application characteristics of an application performing the uplink communication. A transmit power for the wireless device to use for the uplink communication may be selected based on the transport block size providing more robust communication characteristics than required for the current channel conditions. In particular, transport power selection may be biased towards a reduced transmit power based on the transport block size providing more robust communication characteristics than required for the current channel conditions.

Abstract: The disclosure describes apparatus and methods for including downlink control information (DCI) normally associated with the physical downlink control channel (PDCCH) within a physical downlink shared channel (PDSCH) to reduce power consumption for a user equipment (UE) operating in a Long Term Evolution (LTE) radio resource control (RRC) connected mode. An enhanced NodeB base station can be configured to generate DCI associated with a future downlink resource assignment or uplink grant for the UE on the PDSCH or a physical uplink shared channel (PUSCH), and then include this DCI within the payload of a current PDSCH communication, such that the PDCCH does not need to be decoded by the UE during a time when DCI for future PDSCH communication is included within a current PDSCH.

Abstract: The disclosure describes procedures for including downlink control information (DCI) within a physical downlink shared channel (PDSCH) communication to reduce power consumption for a user equipment (UE) operating in a Long Term Evolution (LTE) network. A network apparatus can be configured to identify an expected DCI change for the UE, determine whether an LTE subframe location for the DCI change is known, generate either a general or a specific DCI change indicator, and send the corresponding DCI change indicator to the UE on the PDSCH. The specific DCI change indicator can include a bitmap identifying a particular upcoming LTE subframe where the UE is required to decode the PDCCH for DCI, and the general DCI change indicator can include a bit flag identifying a time associated with one or more upcoming LTE subframes when the UE should decode the PDCCH for DCI.

Abstract: A method of modulating transmission power to facilitate in-device coexistence between wireless communication technologies is provided. The method can include determining a scheduled time period during which data is received by a device via a first wireless communication technology. The method can further include reducing a transmission power of a transmission from the device via a second wireless communication technology to a threshold level prior to the scheduled time period and controlling the transmission power so that the transmission power does not exceed the threshold level during the scheduled time period. The method can additionally include, subsequent to the time period, increasing the transmission power to a level exceeding the threshold level.

Abstract translation: 站（STA）可以以规则的间隔接收消息（例如，信标帧），并对所接收的消息执行测量。 STA保持最近测量值的运行平均值，并在每个新的测量间隔之后更新运行平均值。 在某些测量机会中，STA不能接收预期的消息，因此STA不能执行测量; 当发生这种情况时，STA可以选择替代值，用于下次计算运行平均值时的错过测量。 作为一个示例，STA可以将该值替换为先前执行的测量用于错过测量。 作为另一示例，STA可以将预定的低值替换为错过的测量。 基于给定时间点的运行平均值，STA可以采取行动，例如启动漫游扫描或切换到不同的无线接口。

Abstract: Methods and apparatus to mitigate interference among multiple wireless subsystems of a wireless communication device are described. A host processor obtains configurations for a plurality of wireless subsystems and evaluates whether potential or actual coexistence interference exists between two or more of the wireless subsystems. The host processor provides configuration information and link quality reporting parameters to and obtains link quality reports from at least two wireless subsystems. When link quality for at least one wireless subsystem fails a set of link quality conditions, the host processor adjusts data requirements for applications that communicate through one or more of the wireless subsystems and/or adjusts radio frequency operating conditions for one or more of the wireless subsystems to mitigate interference among the wireless subsystems.
