A receiving device re-establishing a packet data convergence protocol (PDCP) entity. The receiving device resets a robust header compression (ROHC) context. The receiving device receives packet retransmissions having header compression based on the ROHC. The receiving device performs decompression of the packet retransmissions. The receiving device discards duplicate packets after performing the decompression of the packet retransmissions.

Robust header compression handling during packet data convergence protocol re-establishment

In some implementations, a mobile device may determine a set of target orientations of the mobile device in which an antenna lobe of the mobile device is pointed toward the satellite, the set of target orientations based on: an orientation of the antenna lobe relative to the mobile device, and a location of the satellite relative to the mobile device. The mobile device may determine a current orientation of the mobile device. The mobile device may provide, at a user interface (UI) of the mobile device, guidance for rotating the mobile device from the current orientation to an orientation within the set of target orientations.

Mobile device orientation guidance for satellite-based communications

A UE may include one or more application processors and a modem processor. The modem processor may include flow priority engine configured to receive, from the one or more application processors, requests for determining priority treatment of one or more packet filters of one or more uplink transmissions and transmit the one or more uplink transmissions to a base station based on priorities of the one or more uplink transmissions. The priorities of the uplink transmissions may be determined based on at least one of the requests for priority treatment received from the one or more application processors, mapping of uplink transmissions to radio bearers, the priorities of the radio bearers, or one or more configuration rules.

Method and apparatus for prioritizing uplink or downlink flows in multi-processor device

In a wireless network, a user equipment (UE) may support reflective quality of service (QoS), where QoS applied to uplink packets is implicitly derived from downlink packets. For example, when the UE receives a downlink packet that includes a reflective QoS (RQoS) indicator and a QoS flow identifier (QFI), the UE may apply the same QoS associated with the downlink packet to an uplink packet with one or more attributes that match the downlink packet. However, for a received downlink encapsulating security payload (ESP) packet that includes an RQoS indicator and a QFI, a modem cannot determine an uplink security parameters index (SPI) and downlink SPI pairing needed to enable RQoS because the uplink/downlink SPI pairing is known only by the upper layer. Accordingly, some aspects described herein enable the modem to learn uplink/downlink SPI pairings for ESP packets and thereby enable RQoS for ESP packets.

Reflective quality of service for encapsulating security payload packets

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless receiver may receive, from a radio bearer configured to use header compression and at a lower layer of the wireless receiver, a plurality of packets based at least in part on the header compression, wherein the lower layer receives the plurality of packets in an out-of-order sequence. The wireless receiver may deliver, from the lower layer of the wireless receiver to a higher layer of the wireless receiver, the plurality of packets, after header decompression according to the out-of-order sequence, based at least in part on at least one threshold. Numerous other aspects are provided.

Out-of-order packet delivery and decoding with header compression

When sending a first set of packets is determined to be prioritized over sending a second set of packets, and when each first header of each of the first set of packets and each second header of each of the second set of packets is determined to be compressed, an apparatus may compress the first header of each of the first set of packets using a first CID associated with a connection. Further, the apparatus may compress the second header of each of the second set of packets using a second CID associated with the connection. The apparatus may send the first set of packets through the connection. The apparatus may send, after sending the first set of packets, the second set of packets through the connection.

Prioritization for a packet communication protocol with header compression

A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a core network entity. The apparatus sends a request for a device identifier of a UE to the UE. The apparatus receives a response message including the device identifier of the UE from the UE. The apparatus determines to maintain, establish, terminate or prevent a connection with the UE through WLAN access based on the device identifier of the UE.

Support blacklisting devices on WLAN access

Aspects relate to a priority mechanism for prioritizing network identifiers, for example SSIDs. As described herein, a UE may obtain one or more network identifier sets, each of the one or more network identifier sets having one or more network identifiers for a first RAT and a priority level, determine one or more of the network identifier sets that are under control of a second RAT, and after the determining, manage connections to the first RAT based, at least in part, on the priority level of the network identifier sets.

Prioritization for WLAN access for LTE managing WLAN connectivity

Apparatus and methods for power management in a wireless communication device include detecting a change in a serving cell for data communication from a first cell to a second cell; determining whether a terminal equipment (TE) is in a low power state; detecting a first technology type of the first cell and a second technology type of the second cell; determining whether the second technology type is a different technology mode than the first technology type; sending a cell change notification to a data processor associated with the TE when the second technology type is in the different technology mode than the first technology type and the TE is not in a low power state; and suppressing the sending of the cell change notification when the second technology type is not in the different technology mode and the TE is in the low power state.

Apparatus and methods for enhanced user equipment power management via controlled cell change notifications

A method includes receiving a request to bind a port to a requesting application and determining whether an open application is bound to the port. The method further includes binding the requesting application to the port when the open application is not bound to the port.
