    Abstract: Systems and techniques are disclosed to separate paging and access cell selection (and use) among available cells based on different paging cell and access cell requirements and specific service availability. A UE selects a first cell that meets paging cell requirements as a paging cell and a second cell that meets service requirements as an access cell. Once the UE selects a paging cell, the UE camps on the paging cell to wait for a paging request or a mobile originated request. The UE can select and camp on the access cell prior to a data need, where latency requirements are strict, or delay access cell selection until there is data to transmit where latency requirements are more lax. The UE may also include measurement information of surrounding cells with a paging response/service request, which a core network uses to speed up establishment of dual connectivity or carrier aggregation.

    Abstract: Methods and apparatus for radio link control switching are disclosed. The methods and apparatus determining a communication mode at a first device for a radio bearer or packet flow of a radio connection between the first device and a second device including determining whether to operate in a first communication mode providing packet loss recovery or packet reorder, or to operate in a second communication mode providing no packet loss recovery. A first indication is transmitted to the second device related to whether the first communication mode or the second communication mode should be used for the packet flow, and a second indication is transmitted to the second device indicating whether packet buffering is to be maintained. The communication mode for the packet flow of the radio connection between the first communication mode and second communication mode is then switched based at least on the first indication.

    Abstract: A wireless device may receive a radio link control (RLC) protocol data unit (PDU) from a lower layer (e.g., from a media access control (MAC) layer) when processing communications (e.g., packets) received from another wireless device. The receiving wireless device may identify that the PDU is an RLC service data unit (SDU) segment based at least in part on an indication corresponding to a sequence number associated with the RLC SDU segment. The receiving wireless device may then determine that the RLC SDU segment is received out of order based on previously received PDUs or previously received RLC SDU segments, and initiate a reassembly timer based on the out of order determination for the RLC SDUs. If the remaining RLC SDU segments (e.g., that complete the RLC SDU) are received before reassembly timer expires, the wireless device may reassemble the RLC SDU to be passed to a higher layer.

    Abstract: Techniques for refreshing security keys for enciphering and deciphering packets in a wireless communications system are provided. An exemplary method generally includes transmitting, while in a state with no dedicated resources allocated to the UE, a first message to request resumption of a radio resource control (RRC) connection, the first message encrypted using a first set of one or more keys, receiving, in response to the first message, a second message encrypted using the first set of one or more keys or a second set of one or more keys, determining, based on an indication in the second message or received prior to the second message, whether portions of the second message are encrypted using the second set of one or more keys, and processing the second message using the first set of one or more keys or the second set of one or more keys, based on the determination.

    Abstract: Some aspects provide for establishing a radio connection for the wireless communication, determining a configuration for whether to segment one or more packets for the wireless communication using the established radio connection, and communicating the one or more packets based on the determined configuration. Some aspects provide for assembling a first frame comprising one or more packets, transmitting the first frame, determining whether a portion of one or more packets was truncated during the assembling of the first frame, and transmitting a second frame comprising at least the truncated portion of the one or more packets of the first frame. Some aspects provide for receiving a first frame comprising one or more packets, determining that a portion of one or more packets is truncated, and determining whether to ignore as padding at least the truncated portion of the one or more packets of the first frame.

    Abstract: Methods, systems, and devices for wireless communication are described. In some wireless communications systems, a transmitting device may identify a Radio Link Control (RLC) service data unit (SDU) to be transmitted to a receiving device. In some cases, the transmitting device may not have access to sufficient resources to transmit the entire RLC SDU. As such, the transmitting device may segment the RLC SDU into RLC SDU segments, and the transmitting device may transmit the RLC SDU segments to the receiving device. If an RLC layer at the receiving device receives one or more RLC SDU segments out of sequence, the RLC layer may initiate a reassembly (or reordering) timer. The RLC layer may reassemble the successfully received RLC SDU segments to be passed to upper layers. Once the timer expires, the RLC layer may declare that the missing RLC SDU segments are lost.
