Abstract: Automatic cell discovery of a source radio access network (RAN) cell by a neighboring, target RAN by initiating a fake handover of a user equipment (UE) from a source RAN cell to a target RAN. A source RAN cell initiates a handover request using handover signaling to the target RAN(s). The handover request is a fake handover request without actual intention of handing over UE to the target RAN. The source RAN cell includes information in initiated handover request that can be used by target RAN to discover source RAN cell. The handover request will fail, because the handover request is not for any actual UE moving from the source RAN cell to the target RAN. However, the target RAN becomes aware of the source RAN cell as a result of this process and can add the source RAN cell (e.g., its EARFCN) to a list of its neighboring cells.

Abstract: In a wireless communication system that traverses a physical barrier, a serving transceiver determines a downlink beamforming matrix. The serving transceiver determines a downlink power based on the downlink beamforming matrix. A network transceiver beamforms and amplifies a downlink signal based on the downlink beamforming matrix and downlink power. The network transceiver wirelessly transfers the downlink signal through the physical barrier to the serving transceiver. Contemporaneously, the network transceiver determines an uplink beamforming matrix. The network transceiver determines an uplink power based on the uplink beamforming matrix. The serving transceiver beamforms and amplifies an uplink signal based on the uplink beamforming matrix and uplink power. The serving transceiver wirelessly transfers the uplink signal through the physical barrier to the network transceiver.

Abstract: Methods and apparatus for supporting transmission bursts in unlicensed spectrum are described. Different sets of sub-bands within a downlink bandwidth portion of unlicensed spectrum can be, and sometimes are, occupied during different DL transmission bursts depending on channel availability. A user device is configured with channel usage information, e.g. N bitmaps, each bitmap indicating a different control channel resource allocation that may be used for communication with the UE, and/or reference signal information. The UE determines the occupied sub-bands in a DL transmission burst over the bandwidth portion, and determines control channel resource information based on the determined occupied sub-channels. The UE determines CSI-RS measurement locations based on determined sub-band occupancy. In some embodiments, the UE performs in-sync and out-of-sync evaluations based BLER threshold scaling factors, which are based on sub-band occupancy.

Additionally or alternatively, content storage may include fragmentation of the content into a number of segments or segments of a specified size. Content may further be paused and resumed between multiple devices, taking into account the capabilities and compatibilities of the devices and a network through which the content is to be delivered.

Abstract: Radio Link Control ACK/NACK is conditionally suppressed. A first wireless communications device including a radio transmitter identifies a first packet flow for which end to end packet retransmission is supported. The first wireless communications device identifies a Packet Data Convergence Protocol (PDCP) packet corresponding to Radio Link Control Acknowledged Mode (RLC AM), said identified packet being included in the identified first packet flow. The first wireless communications device generates an Acknowledged Mode Protocol Data Unit (AM PDU) including a No RLC ACK Required (NRAR) indicator set to indicate RLC ACK is not required, and the radio transmitter in the first wireless communications device transmits the AM PDU, e.g., an AMD PDU, to a second wireless communications device. The second wireless communications device receives the transmitted AM PDU, recovers the NRAR indicator value, and based on the communicated value of the NRAR indicator, determines to suppress RLC ACK/NACK.

Abstract: A communications device transmits data in preconfigured resources of an uplink of a wireless communications network by performing a procedure to determine whether the communications device can transmit signals in the preconfigured resources of the uplink, and if the communications device determines that it can transmit signals in the preconfigured resources, transmitting signals representing the data in the preconfigured resources. The procedure to determine whether the communications device can transmit signals in the preconfigured resources of the uplink includes a transmission parameter confirmation procedure which confirms that a value of one or more transmission parameters to be used for transmitting the signals representing the data can be used for the signals representing the data to be detected by an infrastructure equipment of the wireless communications network.

Abstract: Embodiments provide system and methods for a DDoS service using a mix of mitigation systems (also called scrubbing centers) and non-mitigation systems. The non-mitigation systems are less expensive and thus can be placed at or near a customer's network resource (e.g., a computer, cluster of computers, or entire network). Under normal conditions, traffic for a customer's resource can go through a mitigation system or a non-mitigation system. When an attack is detected, traffic that would have otherwise gone through a non-mitigation system is re-routed to a mitigation system. Thus, the non-mitigation systems can be used to reduce latency and provide more efficient access to the customer's network resource during normal conditions. Since the non-mitigation servers are not equipped to respond to an attack, the non-mitigation systems are not used during an attack, thereby still providing protection to the customer network resource using the mitigation systems.
