Abstract: The disclosure relates in some aspects to location reporting and paging for satellite communication. In one aspect, the disclosure relates to a user terminal (UT) sending a message to report information about the UT's location. A threshold may be used to control whether (e.g., when) the UT reports its location. The location information may be used to enforce area (e.g., country) restrictions for the UT. In one aspect, the disclosure relates to forwarding paging messages between network access controllers. For example, a network access controller that is not able to page a UT may forward a paging message to another network access controller. In one aspect, the disclosure relates to a list of paging areas that indicates where a UT need not perform a paging area update.

Abstract: Various apparatuses and methods for transmitting uplink data of an application at a user equipment are provided. In one aspect of the disclosure, uplink data of an application at a user equipment (UE) is transmitted to a network. A first amount of the uplink data expected to be buffered at a radio link control (RLC) layer is determined based on a latency of the application. A second amount of the uplink data available for transmission at the RLC layer is determined based on information provided by a modem of the UE. A data rate of the application is dynamically adjusted based on a difference between the first amount and second amount of the uplink data. In another aspect of the disclosure, an amount of the application data buffered at the RLC layer is maintained to be greater than a predetermined threshold that sets a Happy bit at an unhappy setting. The unhappy setting is communicated to the network, a data rate of the application is increased in response to an increased grant from the network due to the unhappy setting. In another aspect of the disclosure, a maximum modem supported data rate at which the user equipment (UE) transmits uplink data of an application is determined based on an uplink channel capacity estimate, a modem queue length estimate, a codec rate change frequency of the application, and a delay threshold of the modem queue.

Abstract: Methods and apparatus for avoiding power scaling and controlling transmit power in uplink data transmission are provided. If a user equipment (UE) would be transmit-power limited when transmitting data concurrently on an uplink high speed dedicated physical control channel (HS-DPCCH) and an uplink data channel, the UE may forgo building data for transmission on the uplink data channel to avoid power scaling. If the UE would be transmit-power limited when transmitting data concurrently on an HS-DPCCH and a dedicated physical control channel (DPCCH), the UE may reduce the transmission power of a portion of the data transmitted on the DPCCH to avoid power scaling. The UE may also boost transmission power of a negative acknowledge transmission above network-specified power level.
