Abstract:
A wireless device, acting as an AP or GO, collects information comprising transmission opportunity (TxOP) status and interference threshold from stations communicating with the AP/GO. When the collected information is changed from previous collected information, the AP/GO broadcasts the collected information in a broadcast frame (e.g., beacon frame) to stations communicating with the wireless device. The beacon frame may include interference thresholds for each side of a link. The stations may then adjust their transmit power to remain within their associated interference threshold.
Abstract:
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.
Abstract:
Embodiments of computer-implemented methods, systems, computing devices, and computer-readable media are described herein for opportunistically transitioning service flows of mobile devices between being direct and indirect. In various embodiments, a proximity between first and second mobile devices that are in wireless communication with each other may be monitored. In various embodiments, a selective transition of a service flow between the first and second mobile devices from being indirect through the radio network access node using a first radio access technology ("RAT") to being direct using a second RAT may be facilitated, e.g., responsive to a determination that a first criterion has been met. In various embodiments, a selective transition of the service flow from being direct using the second RAT to being indirect using the first RAT may be facilitated, e.g., responsive to a determination that a second criterion has been met.
Abstract:
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.
Abstract:
A method for an uplink power control mechanism is presented. In one embodiment, the method includes receiving an allocation information element (IE) in conjunction with a ranging process. The method includes processing the allocation information element to determine power control parameters including a first parameter about offset control and a second parameter about noise and interference level. The method also includes calculating the power value for each channel based at least in part on two or more power control parameters.
Abstract:
A virtual page number lookup request is received at a virtual Translation Lookaside Buffer (TLB), wherein the virtual TLB includes an instruction TLB and a data TLB. A lookup of the virtual page number in the virtual TLB is performed. A physical page number corresponding to the virtual page number in the virtual TLB is returned.
Abstract:
Some wireless communications environments, such as Wi-Fi, may include inexpensive power amplifiers where the power adjustment may not be accurate, and may also include pathloss measurement errors that are high enough to degrade performance of a power control algorithm. To address this issue, an exemplary aspect is directed toward a finite state power control algorithm and technique that, while designed for next generation Wi-Fi standards, such as 802.11ax, can in general be used with any wireless communication protocol or standard.
Abstract:
The application relates to the management of measurements for the minimization of drive tests MDT. In particular it relates to the measurement of uplink parameters such as UL Coverage Optimization, QoS Verification, or IP Throughput by an entity of the radio access network such as a NodeB or a RNC. In the past, the MDT configuration was always passed on to one or more UEs being served by the particular eNB. Consequently, only downlink parameters could be measured and collected in the past in the scope of MDT. Now, the eNB itself has to perform certain measurements (pertaining to UL traffic), and to combine the results of this eNB based measurements later on with the results reported by the UE over the Uu air interface. Therefore, the application proposes a new parameter in MDT Configuration, which is received from the EM, to turn on/off MDT Uplink Measurements. The trace-based MDT configuration received from the EM (1202) is split into two parts (1204), whereby the new parameter is processed on the CN/RAN side for performing the requested UL measurements, while the rest of the MDT configuration parameters is sent over the air interface to the respective UE (1206). Furthermore, it proposes to combine the MDT UL measurements performed in the RNC/NB/eNB itself and the measurements collected by the UE in a single trace-base MDT report (1212).
Abstract:
A user equipment (UE) is arranged to send an uplink power reference signal to an enhanced Node B (eNB) associated with multiple reception points (RPs), to receive identification of an RP set and a downlink reference signal power level, to determine a path loss estimate for each downlink reference signal received from RPs of the RP set, to determine an uplink power level that is a function of the path loss estimates determined for the downlink signals received from the RPs of the RP set, and to use the determined uplink power level during communication with the multiple RPs.
