摘要:
Power control schemes for D2D communications are described. The schemes control the transmission power of a UE during D2D communications in a manner that reduces interference while maintaining the D2D communications link and the cellular link with the eNB. Open-loop and/or closed-loop techniques are employed.

Uplink power control in a macro cell in a wireless network comprises transmitting a reference signal from a base station device to at least one wireless device within the macro cell. The macro cell comprises the base station device and at least one radio transmitter device that is communicatively coupled to and remote from the base station device. The base station device and one or more radio transmitter devices could be selected to be a transmission point, a reception point or a combination thereof, for each wireless device. Information relating to a transmission power of the base station device is also transmitted to the at least one wireless device. An uplink signal is received from the at least one wireless device containing information relating to an uplink power determination that is based on the reference signal and the information relating to the transmission power of the base station device.
摘要:
Examples are disclosed for analyzing uplink interference or pathloss associated with uplink coverage provided by one or more base stations for a wireless network based on logged uplink signal quality or interference information at least temporarily maintained at a wireless device. In some examples, a base station may request the logged uplink signal quality or interference information from the wireless device. The wireless devices may have been configured to measure uplink signal quality or interference characteristics for one or more communication links between the wireless device and one or more base stations of the wireless network. The logged uplink signal quality or interference information may be based on the measured uplink signal quality or interference characteristics. Other examples are described and claimed.

摘要:
An apparatus and method for processing fast feedback payload data to generate symbols for transmission through a fast feedback channel in a wireless network are presented. The technique first encodes payload data using a tail biting convolutional code. The encoded bits are then de-multiplexed to five different data subblocks in a sequential fashion. Subblock interleaving is then used to interleave the data of the subblocks according to a predetermine scheme. A bit selector then selects interleaved subblock bit for output. The selected bits may then be modulated by a modulator using quadrature phase shift keying (QPSK). The resulting symbols may then be mapped to a predetermined fast feedback subcarriers within a feedback channel.

摘要:
Embodiments of computer-implemented methods, systems, computing devices, and computer-readable media are described herein for assigning transmission power to one or more components carriers in an uplink transmission utilizing carrier aggregation. In one embodiment, power is assigned to a component carrier based on the priority level of the component carrier. In another embodiment, power is assigned based on absolute priority order. In yet another embodiment, power is assigned based on relative priority order.
摘要:
Embodiments described herein relate generally to a user equipment (“UE”) that is to transmit and receive signals associated with synchronization. The UE may be receive signals associated with synchronization from a plurality of synchronization sources, such as an evolved Node B (“eNB”), a global navigation satellite system (“GNSS”), or another UE. The UE may synchronize to a signal received from a synchronization source based on a priority associated with that synchronization source and/or signal. However, if the UE does not receive any signals associated with synchronization, the UE may generate and transmit a signal that indicates a request for synchronization.
