摘要： Systems and methods enabling uplink power sharing for dual connectivity are disclosed. Embodiments are described herein in which a maximum Uplink (UL) power on each link is configured statically, semi-statically, or dynamically. In general, regardless of the embodiment, uplink power for uplink transmissions from a wireless device on two simultaneous links is controlled such that the total uplink power does not exceeds a maximum UL transmission power level while, in some embodiments, taking into account priorities of the two links and/or priorities of various uplink channels transmitted by the wireless device on the two links. Notably, while the embodiments described herein focus on dual connectivity, the embodiments described herein can easily be extended to any number of two or more simultaneous links.

摘要： A device-to-device (D2D) communication network supports a wireless D2D link between a first wireless transceiver and a second wireless transceiver, the second wireless transceiver accessing a cellular communication network via the first wireless transceiver. The first wireless transceiver receives capability information from the second wireless transceiver on wireless D2D communication resources and transmits, to the second transceiver, power saving information about a power saving mode configuration based on the received capability information. The power saving information comprises information about sleep periods and active periods of the second transceiver. A sync signal is transmitted with a timing based at least partly on the power saving mode configuration, for facilitating re-synchronization of the second wireless transceiver with the first wireless transceiver in conjunction with an end of a sleep period of the second wireless transceiver in accordance with the power saving mode configuration.

摘要： According to an aspect, a wireless terminal performs a method for a random access procedure in a wireless network. The method includes maintaining a preamble transmission attempt counter that tracks the number of random access preamble transmissions that are triggered and/or initiated in the random access procedure, including random access preamble transmissions that are aborted prior to completion of the transmission. The method also includes terminating the random access procedure in response to determining that the preamble transmission attempt counter indicates that a predetermined threshold number of transmission attempts have been made. Reports pertaining to failed preamble transmissions may be sent to the network, which then adjusts a configuration of the wireless terminal. The wireless terminal may also track time during an interval in which a preamble may be used in the random access procedure and terminate the random access procedure in response to determining that the interval has expired.
