Abstract:
Methods, systems, and devices for wireless communication are described. A wireless device may identify a collision of a first DRX wakeup occasion of a first radio access technology (RAT) and a second DRX wakeup occasion of a second RAT within a discontinuous reception (DRX) interval. The wireless device may identify an offset change for a DRX wakeup occasion of at least one RAT based on the collision. In some cases, the wireless device may transmit a paging offset change request message to a network node, such as a base station or core network node, based on the identified offset change. The wireless device may receive, from the network node, a paging offset acceptance message in response to the paging offset change request message indicating a timing offset for changing the first DRX wakeup occasion or the second DRX wakeup occasion. In some cases, the wireless device may receive an indication from the network node to change a wakeup occasion.
Abstract:
Methods and devices address managing uplink resource grants on a wireless communication device configured with a radio frequency (RF) resource supporting at least a first and second radio access technology (RAT). When a first protocol stack is in a radio resource control (RRC)-connected state in a network associated with the first RAT, a tune-away event on the first protocol stack may be detected in which the RF resource tunes from the network associated with the first RAT to a network associated with the second RAT, and the RF resource tunes back to the network associated with the first RAT after a tune-away duration. A first scheduling request procedure may be triggered on the first protocol stack, and a protection window mechanism may be implemented during a time window following the tune-away duration.
Abstract:
Apparatuses and methods for a wireless communication device having a first Subscriber Identity Module (SIM) and a second SIM to manage communication via the first SIM and the second SIM are disclosed. The method can include, but is not limited to, sending a first message including an indication of an extended signaling capability, receiving a second message including an inquiry regarding the extended signaling capability, and sending a third message including extended capability information, responsive to receiving the second message.
Abstract:
Embodiments include systems and methods for managing inter-radio access technology (IRAT) procedure concurrency between subscriptions on a multi-subscription multi-active communication device. A device processor may identify a higher-priority subscription and a lower-priority subscription on the multi-subscription multi-active communication device. The device processor may determine whether an IRAT procedure on the lower-priority subscription will overlap in time with an IRAT procedure on the higher-priority subscription. The device processor may calculate a deferral time period for the lower-priority subscription in response to determining that the IRAT procedure on the lower-priority subscription will overlap in time with the IRAT procedure on the higher-priority subscription. The device processor may defer performance of the lower-priority subscription IRAT procedure using the deferral time period in order to perform the IRAT procedure on the higher-priority subscription, and may perform the IRAT procedure on the lower-priority subscription after the deferral time period.
Abstract:
A method for managing emergency alerts includes determining that a first subscription is a designated data subscription (DDS) and a second subscription is a non- DDS; tuning to a secondary common control physical channel (SCCPCH) on the first subscription; and receiving one or more emergency alerts on the first subscription and not on the second subscription.
Abstract:
Embodiments include methods implemented by a processor of a mobile communication device for managing tune-aways by a radio frequency resource supporting a first subscription to support a second subscription. The processor may determine a data loss ratio of the data of a media file that is lost in transmission to the mobile communication device. The processor may compare the data loss ratio of the data to a first data loss ratio threshold and a second data loss ratio threshold, and the processor may block a tune-away event of the radio frequency resource from the first subscription to the second subscription in response to determining that the data loss ratio of the data is greater than the first data loss ratio threshold and less than the second data loss ratio threshold.
Abstract:
Systems, methods, apparatuses, and media are provided for recovery of information from redundancy version packets in systematic encoding environments when a redundancy version packet containing primarily systematic information may be corrupted. A plurality of redundancy version packets may be received at a user equipment device from a transmission device. Each redundancy version packet of the plurality of redundancy version packets may be based on a same group of information bits. A first redundancy version packet of the plurality of redundancy version packets may contain more bits of the same group of information bits than do the other redundancy version packets of the plurality of redundancy version packets. The same group of information bits may be recovered based on one or more second redundancy version packets of the plurality of redundancy version packets but not based on the first redundancy version packet.
Abstract:
The various embodiments include methods and apparatuses for canceling nonlinear interference during concurrent communication of multi-technology wireless communication devices. Nonlinear interference may be estimated using a multilayer perceptron neural network with Hammerstein structure by dividing an aggressor signal into real and imaginary components, augmenting the components by weight factors, executing a linear combination of the augmented components, and executing a nonlinear sigmoid function for the combined components at a hidden layer of multilayer perceptron neural network to produce a hidden layer output signal. At an output layer, hidden layer output signals may be augmented by weight factors, and the augmented hidden layer output signals may be linearly combined to produce real and imaginary components of an estimated jammer signal. A linear filter function may be executed for the components of the jammer signal, and to produce a nonlinear interference estimate used to cancel the nonlinear interference of a victim signal.
Abstract:
Certain aspects of the present disclosure relate to methods and apparatus for a user equipment (UE) to transmit an uplink signal, even though the UE may not have received a negative acknowledgement (NACK) corresponding to the uplink signal from a network due to a tune away period. The method may generally include determining that an acknowledgement / negative acknowledgement (ACK/NACK) signal from a first network corresponding to an uplink signal is scheduled within a tune away period to a second network, and transmitting at least a portion of the uplink signal upon completion of the tune away period based on the determination.
Abstract:
Methods, systems and devices for prioritizing communication technologies to allocate resources in a mobile device. The mobile device may employ a dual subscription, dual active (DSDA) configuration in which two subscriptions may be associated with concurrently active communications, such as voice or data calls. The mobile device may identify current states that indicate the type of communications associated with the subscriptions. In an embodiment, an applications processor within the mobile device may perform the state identifications. The mobile device may determine priorities of the concurrently active subscriptions based on the identified states. In an embodiment, the priorities may be determined by a modem processor within the mobile device. When the priorities are determined to be the same, the mobile device may perform a tiebreaker algorithm to further identify priorities. Based on the determined priorities, the mobile device may allocate resources to favor the subscription with the higher priority.
