A device may determine one or more parameters relating to a network. The device may detect a trigger to alter a hybrid automatic repeat request (HARQ) configuration for the network based on the one or more parameters relating to the network. The device may determine an alteration to the HARQ configuration based on detecting the trigger to alter the HARQ configuration. The device may communicate with a distributed unit or a centralized unit of the network to cause the alteration to the HARQ configuration.

Mitigating interference between transmitters and receivers associated with satellite systems and mobile wireless systems may include receiving information associated with the transmitter, determining a distance between the transmitter and the receiver based on the received information, determining if the distance is less than a distance threshold, estimating an interference level based on determining that the distance is less than the distance threshold, determining if the estimated interference level exceeds an interference threshold, computing an angle between an antenna of the transmitter and the receiver based upon determining that the estimated interference exceeds the interference threshold, and directing, when receiving a signal, a main lobe of a receive antenna pattern of the receiver towards the signal, and forming nulls in the receive antenna pattern in a direction of at least one side lobe of a transmit pattern of the transmitter.

Systems, methods, and devices for assigning user equipment to frequency bands on multiband advanced wireless communication networks. The system may include a multiband controller configured to obtain signal quality indicators from user equipment devices for signals received by the user equipment devices from a first remote radio head for a first frequency band having a maximum frequency greater than 24 GHz and a second remote radio head having a minimum frequency at least 2 GHz greater than the maximum frequency, and in response to the signal quality indicators, issue a command to a user equipment device included in the user equipment devices and operating in the first frequency band to switch to operating in the second frequency band.

Methods, systems, and devices are described for making scaling adjustments with respect to a fractional subsystem in a wireless communications system. To handle the effects of scaling associated with fractional bandwidth systems, different adjustments may be made to maintain certain quality of service (QoS) requirements, for example. Scaling adjustments may include identifying a scaling factor for the fractional subsystem and a parameter and/or a timer associated with the fractional subsystem. An adjustment associated with the parameter and/or timer may be determined based on the scaling factor. The adjustment may be applied with respect to the parameter and/or timer for at least a portion of the fractional subsystem or another portion of the wireless communications system.

A method, an apparatus, and a machine-readable medium are provided for wireless communication in which at least two modems are selected from a set of modems for the wireless communication based on quality of service requirements for and an energy consumption of the wireless communication. In addition, the selected at least two modems are utilized concurrently for the wireless communication.

Energy efficient quality of service aware communication over multiple air-links

An apparatus for capturing a signal of interest, e.g., PSS and/or SSS, captures data transmitted by a first RAT by obtaining access to a receive chain for a second RAT during a measurement gap for the first RAT. The signal of interest transmitted by the first RAT is captured during the measurement gap using the receive chain for the second RAT. Access to a receive chain for the second RAT may be obtained in any one of several ways. For example, access may be obtained by 1) requesting receive chain access for the second RAT for LTE measurements through a virtual flow, 2) entering into a power save mode, 3) tuning to a non-operating channel, 4) setting network allocation vector (NAV) at or above a threshold value, or 5) entering a measurement mode during which the receive chain for the second RAT is prevented from performing WLAN operations.

Capture of PSS and SSS with wireless local area network receive chain

An apparatus for capturing a signal of interest, e.g., PSS and/or SSS, captures data transmitted by a WWAN by obtaining access to a WLAN receive chain for a period of time corresponding to a measurement gap. The signal of interest transmitted by the WWAN is captured during the measurement gap using the WLAN receive chain. Access to a WLAN receive chain may be obtained in any one of several ways. For example, access may be obtained by 1) requesting WLAN receive chain access for LTE measurements through a virtual flow, 2) entering into a power save mode, 3) tuning to a non-operating WLAN channel, 4) setting network allocation vector (NAV) at or above a threshold value, or 5) entering a measurement mode during which the WLAN receive chain is prevented from performing WLAN operations.

A time period associated with each of a plurality of tasks included in a current instance of WWAN data capture/processing by a WLAN processor and a WWAN processor is determined. A total time period comprising the respective time periods of each task is compared to an overall time budget criterion to obtain a comparison outcome. A change in at least one of the tasks based on the comparison outcome is implemented. The change results in an adjustment of the total time period associated with a next instance of WWAN data capture/processing by the WLAN processor and the WWAN processor.

Methods, systems, and devices are provided for system information management in a wireless communications. A user equipment (UE) may identify a first value of a value tag in a first carrier, read a system information block (SIB) on the first carrier associated with the value tag, and identify a second value of the value tag in a second carrier. The UE may compare the first value with the second value and determine whether the read SIB on the first carrier may be utilized on the second carrier. Other techniques may include identifying a first value of a value tag for a first carrier linked with a SIB transmitted over the first carrier. The techniques may include determining a second value of the value tag for a second carrier indicating whether the SIB transmitted over the first carrier may be utilized on the second carrier.

An apparatus for wireless communication obtains a first metric of a cell based on signals received by a WWAN radio tuned to a common frequency, and a second metric of the cell based on signals received by a WLAN radio tuned to the common frequency. The apparatus determines a calibration factor based on the first and second metrics, and performs cell search and cell measurement based on the calibration factor and signals received by the WLAN radio tuned to a target frequency. The common frequency may be a serving frequency of the WWAN, in which case the first and second metrics are one of frequency or power metrics and the calibration factor is one of a frequency offset and a power offset. The common frequency may also be a target frequency for inter-frequency measurements of the WWAN, in which case the calibration factor is based primarily on power measurements.

Methods, systems, and devices are provided that may address problems pertaining to effective transmit power control of a communications device operating in a wireless communications system. Some embodiments utilize mechanisms or techniques with dynamically adaptive steps sizes for transmit power control based on one or more trends. Some of these techniques may identify a trend in the transmit power control (TPC) commands and may adapt a TPC step size as a result. Other techniques may be utilized in which transmit power control is based on multiple interference estimates in a frame slot. Having multiple interference estimates at sub-slot intervals may provide additional transmit power control by allowing more transmit power adjustments, or more appropriate adjustments, for each slot. Metric calculations may be performed on one or more techniques to determine appropriate TPC operations.
