Apparatuses, systems, and methods for user equipment (UE) devices to perform more efficient frequency scans for potential base stations. According to techniques described herein, the UE may determine that it does not have cellular service and determine first information based on a last camped cell. A time period during which the first information was acquired may be determined and one or more frequency scans may be performed. The frequency scans may be limited to a set of frequencies based in part on the time period. Thus, if the time period is less than a first value, the set of frequencies may include a first set of frequencies and if the time period is greater than the first value but less than a second value, the set of frequencies may include the first set of frequencies and a second set of frequencies.

Embodiments are presented herein of apparatuses, systems, and methods for a user equipment (UE) device to adaptively enhance the quality of service (QoS) configuration of a bearer of communications conducted over a cellular network between a UE application and a server. The UE may use various information, including a QoS profile associated with the application, to determine requested QoS parameters and/or whether the UE is permitted to request or access enhanced QoS functionality. The UE may then send a request to the cellular network indicating the requested QoS parameters, and the network may adjust the QoS configuration of the bearer in response. The UE and the network may perform routine QoS measurements and exchange information in order to adaptively maintain and optimize the QoS configuration. These techniques may tend to provide more appropriate QoS to the application, which may improve user experience.

This disclosure relates to energy budgeted cellular service recovery techniques. A wireless device may determine one or more energy budgets for service recovery. It may be determined that cellular service loss is currently occurring. Cellular service recovery may be attempted, where service recovery scan timing for the attempt to recover cellular service is determined based at least in part on the one or more energy budgets for service recovery.

Energy budgeted system recovery

In some embodiments, an apparatus is configured to wirelessly communicate with a base station using a first retransmission parameter in a first frame transmission scheme. In some embodiments, the apparatus is configured to determine a current performance metric and, based on the current performance metric, use a second, different retransmission parameter in a second frame transmission scheme for subsequent communications. In some embodiments, the retransmission parameter is a number of retransmissions or a number of hybrid automatic repeat request (HARQ) processes.

Frame transmission scheme modification

A compressor may obtain information indicative of a transmit delay representative of a time duration that elapses between creation (e.g. by the compressor) of a packet and the transmission of the packet, e.g. over a wireless link. The transmit delay may be determined based at least on information indicative of the uplink capacity of the cellular network. The uplink capacity may be determined/obtained based on the uplink throughput and uplink power headroom. When the compressor receives a negative acknowledgement transmission/packet from the decompressor, if the transmit delay is not greater than a specified threshold value, the compressor may process the received negative acknowledgement packet. If the transmit delay is greater than the specified threshold value, the compressor may first discard the buffered compressed packet scheduled to be transmitted next to the decompressor, and transmit an initialization and refresh (IR) or IR dynamic packet to the decompressor instead.
