Abstract:
A method of wireless communication at a user equipment (UE) includes determining whether a user equipment (UE) is traveling faster than a predetermined speed and determining whether a current serving frequency is dedicated, based on whether the UE is traveling faster than the predetermined speed and/or whether a high-speed flag is set in a received message. The method also includes periodically searching a dedicated frequency from a dedicated frequency list to detect a dedicated cell with a signal quality above a predetermined threshold and switching to the dedicated cell, when the signal quality of the dedicated cell is above the predetermined threshold.
Abstract:
A user equipment (UE) enables reselection by supplementing dedicated priority information received from a network with proprietary priority-based reselection parameters stored in a UE memory. The reselection is performed when a currently camped-on cell does not broadcast priority-based reselection parameters. The proprietary priority-based reselection parameters include threshold parameters such as high priority thresholds, low priority thresholds, signal strength thresholds and related reselection timers.
Abstract:
A user equipment (UE) reduces latency during a redirection procedure, such as a circuit-switched fallback (CSFB) procedure. In one instance, the UE searches and measures each frequency of a received redirection list of frequencies to determine a strongest frequency. The UE decodes a system information block (SIB) from one or more non-strongest frequencies. The UE then determines whether to wait for a system information block from the strongest frequency based on a metric. The UE determines which of the one or more non-strongest frequencies are selected based on the metric when deciding not to wait for the system information block from the strongest frequency.
Abstract:
A method of wireless communication includes delaying transmission of a first RAT measurement report, when a first time to trigger (TTT) timer for a first RAT expires, until a second TTT timer of a second RAT expires or resets. The method may include transmitting a second RAT measurement report when the second TTT timer expires. The method may also include transmitting the first measurement report when the second TTT timer resets and the first TTT timer is active.
Abstract:
A user equipment (UE) with multiple receive chains and one or more subscriber identity modules improves radio access technology (RAT) measurements when one or more of the subscriber identity modules are active and valid measurement gaps or consecutive idle time slots are unavailable for the radio access technology measurements. The UE communicates with a first receive (RX) chain for a first subscriber identity module (SIM). The UE also performs the radio access technology (RAT) measurement with a second receive (RX) chain while maintaining communications with the first receive chain.
Abstract:
In a multi-subscriber identity module (SIM) device for wireless communication, data usage is transferred from one subscription to another subscription. When it is determined the data utilized for a first subscription associated with a first SIM of the multi-SIM device is above a first data allowance threshold, then the data communication associated with the first subscription is transferred to a second subscription associated with a second SIM of the multi-SIM device. The transferring may occur when data utilized for the second subscription is below a second data allowance threshold.
Abstract:
In a method of wireless communication, a base station receives, from a network device, a periodic interference measurement report corresponding to each of a plurality of downlink time slots within a subframe. The base station also receives a serving cell signal quality reported from a user equipment (UE). The base station schedules a number of downlink time slots for transmission by the UE based at least in part on the received interference measurement reports and the received serving cell signal quality and/or or if high priority IRAT neighbors are configured.
Abstract:
A user equipment (UE) prioritizes searches and/or measurements of neighbor cells/frequencies based on a level of mobility of a UE. In one instance, the UE identifies a priority of a layer of a radio access technology (RAT) to be measured or searched and identifies a level of mobility of the UE. A sensor module of the UE may determine the level of mobility of the UE and generate an indication corresponding to the level of mobility of the UE. The UE prioritizes a periodicity of interlayer search and/or measurement based on the priority of the layer to be measured and the level of the mobility of the UE.
Abstract:
In a method and apparatus for wireless communication, reselection threshold are adjusted based whether a neighbor cell is an inter-frequency neighbor cell or an inter-radio access technology (IRAT) neighbor cell. A cell reselection serving cell threshold is an indicator for determining when to perform cell reselection. Cell reselection is performed in accordance with the cell reselection serving cell threshold.
Abstract:
A user equipment (UE) avoids entering a limited service state when the UE enters a weak coverage area where a communication service outage occurs with respect to a first radio access technology (RAT) and a second RAT. In one instance, the UE remains on the first RAT during the communication service outage, based on a location of the UE by preventing switching from the first RAT to a second RAT.
