Technology to provide link aware streaming adaptation is disclosed. In an example, a mobile device can include computer circuitry configured to: receive a manifest file for an HTTP adaptive stream from a node; determine a physical layer goodput of the mobile device with the node; and select a representation in the manifest file for a selected period based, at least in part, on the physical layer goodput.

A radio node may transmit a signal using a transmit power. Then, the radio node may adjust the transmit power within a range of values. The adjustment may include reducing the transmit power when a spatial received signal strength indication (RSSI) metric of the radio node is greater than a first threshold value and a coverage criterion is met. Note that the spatial RSSI metric of the radio node may correspond to a set of temporal RSSI metrics of the radio node received from neighboring radio nodes. Moreover, the coverage criterion may be that less than a portion of RSSI measurements of the radio node associated with electronic devices, which are communicatively attached with the radio node, is less than a second threshold value. Alternatively, the adjustment may include increasing the transmit power when the spatial RSSI metric is less than the first threshold value.

Disclosed are a wireless communication method and a wireless communication device. A device for managing multiple systems causing interference to a reference point, comprising one or more processors, the processors being configured to: acquire a total amount of interference that is allowed to be caused by the multiple systems at the reference point, determined by another device; on the basis of the acquired total amount of interference, determining a communication resource for each of the multiple systems, such that the interference caused at the reference point by the multiple systems when communicating using the communication resources is different and the sum of interference caused by the multiple systems does not exceed the total amount of interference; and notifying each system of the corresponding communication resource determined for the system.

An acoustic network is located in a formation traversed by a borehole having a pipe contained therein. The acoustic network includes a backbone network having a number of backbone modems engaging the pipe and acoustically communicating along the pipe using a first modulation technique. A number of end node modems acoustically communicate using a second modulation technique orthogonal to the first modulation technique. At least one of the backbone modems is a bridge hub modem that is coupled to both the backbone network and an end node modem and communicates with the backbone network using the first modulation technique and with the end node modem using the second modulation technique. The end node modems may have a hibernation mode defined by low energy usage with no transmission or receipt of data, and a transmission mode defined by transmission of data by the end node modem.

Certain aspects of the present disclosure provide techniques for interference control for uplink transmission, for example, using multiple transmission configurations (e.g., antennas, beams, and/or antenna panels). A method that may be performed by a user equipment (UE) includes determining a transmit power for one or more uplink transmissions to a base station (BS) using one or more transmit power parameters. The one or more transmit power parameters are based, at least in part, on a transmission configuration of the one or more uplink transmissions. The method generally includes transmitting the one or more uplink transmissions to the BS using the determined transmit power.

A base station includes a transmitter which transmits an offset value for a transmission power of a sounding reference signal (SRS) to a terminal apparatus; and a receiver which receives the SRS at the transmission power controlled by the terminal apparatus. The offset value used to control the transmission power is set within one of a first offset setting range having a first lower limit value and a first upper limit value and a second offset setting range having a second lower limit value and a second upper limit value. A difference between the first and second lower limit values equals a difference between the first and second upper limit values. A step width of the offset values within the first offset setting range equals a step width of the offset values within the second offset setting range. The SRS is a periodic SRS (P-SRS) or an aperiodic SRS (A-SRS).

Techniques for performing path loss (PL) compensation in coordinated multipoint (CoMP) systems are provided. A method for wireless communications by a user equipment (UE) is provided. The method generally includes selecting, from a plurality of transmission points involved in uplink (UL) coordinated multipoint (CoMP) operations with the UE, a transmission point to associate with for path loss (PL) compensation, and adjusting power of one or more transmissions based on path loss measured based on the selected transmission point.

Provided is a communication control device including an obtaining unit, in a radio communication system including a primary base station to which a primary terminal is connected, and a secondary base station to which a secondary terminal is connected by secondarily using a frequency channel for the primary base station, obtains at least one of a quality report containing a communication quality indicator measured by the primary terminal and a quality report containing a communication quality indicator measured by the secondary terminal, and an interference control unit that instructs the secondary base station to reduce transmission power, when it is determined that adverse interference is present in the radio communication system, based on the communication quality indicator contained in the quality report obtained by the obtaining unit.

In this application, a terminal determines a power control parameter, and the terminal determines a transmit power based on the determined power control parameter. The power control parameter includes an interference impact parameter or a path correction parameter of a downlink path loss, and the path correction parameter of the downlink path loss is used to correct a downlink path loss participating in calculation of the transmit power. The interference impact parameter and the path correction parameter of the downlink path loss are determined and obtained based on neighboring cell information of the terminal, and the neighboring cell information includes some or all of the following information: a reference signal transmit power of a neighboring cell, an uplink interference over thermal noise ratio of the neighboring cell, and uplink load of the neighboring cell.

Embodiments are provided for implementing network adaptation schemes, including small cell on/off adaptation and transmission power control. In an embodiment method for supporting network adaptation, a network component receives a discovery reference signal (DRS) from a network controller that is in a switch-off transmission mode. The network component then performs measurements according to the DRS, and reports the measurements to a network associated with the network controller. In return, the network component receives a radio resource control (RRC) signaling from the network. The RRC signaling includes configuration information allowing a connection between the network component and the network controller. The network component then connects with the network controller in accordance with the configuration information.
