Abstract: Aspects of the subject disclosure relate to methods for detecting a link failure between the first network device and a destination node, receiving a data packet addressed to the destination node, and rewriting encapsulation information of the first data packet. Subsequent to rewriting the encapsulation information of the first data packet, the first data packet is forwarded to a second network device (e.g., using updated address information in the packet header), wherein the second network device is paired with the first network device in the virtual port channel. In certain aspects, systems and computer readable media are also provided.

Abstract: Methods and devices are described for polar encoding and decoding control information that has been modulated based on one or more identifiers of the transmitter and/or receiver. Some embodiments describe scrambling sequence design for multi-mode block discrimination on control information blind detection and decoding. Separate scrambling masks may be applied to disparate bit fields within a coded DCI message, wherein each of the scrambling masks is derived from a user equipment (UE)-specific identifier, a UE group identifier, or a base station identifier. Frozen bits of the polar code may be used to encode and transmit hybrid automatic repeat request (HARQ) acknowledgment messaging for early retransmission of unsuccessful downlink messages. A tiered process of UE identification may be employed to improve a balance between early termination of the decoding process and success of the UE identification process.

Abstract: Methods, systems, and devices for wireless communications are described. One example method for wireless communications at a user equipment (UE) includes detecting a radio link failure (RLF) condition for a connection between the UE and a network over a first cell group and determining, in response to detecting the RLF condition, whether an air interface resource allocation is available for a signaling radio bearer (SRB) between the UE and the network over another cell group. The method also includes selecting, based at least in part on the determination, one of a plurality of RLF procedures. In some examples, the UE may select a first RLF procedure that fully releases radio resources when no SRB is available and a different, second RLF procedure that partially when an SRB is available between the UE and the network over a second cell group.

Abstract: Disclosed are a wireless communication base station device and a division number determination method that improves the frequency diversity effect while maintaining channel estimation accuracy regardless of the number of divisions in the frequency domain of a transmission signal from a wireless communication terminal device. A determination unit determines the number of divisions in the frequency domain of a transmission signal from a wireless communication terminal device. Here, the determination unit increases the number of divisions in the frequency domain of the transmission signal from the wireless communication terminal device as the number of pilot blocks included in the transmission signal increases. In addition, a scheduling unit schedules allocation to the frequency resources of the divided transmission signal according to the number of divisions determined by the determination unit.

Abstract: Location services for a user equipment (UE) are supported with a Network Exposure Function (NEF) serving as a focal point for any location request. An entity that needs the location of the UE sends a location request to the NEF in the home PLMN or Visited PLMN for the UE. The location request includes, e.g., a type of location request, a required location accuracy, a required response time or some combination of these. The NEF determines whether to use a Gateway Mobile Location Center (GMLC) or a serving Access and Mobility Management Function (AMF) for the UE to obtain the UE location based on the content of the location request and sends the location request to the GMLC or serving AMF accordingly. Additionally, if the serving AMF is used, a serving base station may obtain the UE location and send the UE location to the serving AMF.

Abstract: A method and system to control configuration of dual-connectivity for UEs served by a first NB. A computing system monitors the level of load on a backhaul interface through which the first NB communicates with a core network. And based on the monitored level of backhaul load, the computing system imposes a limit on establishing secondary connectivity with one or more second NBs for one or more UEs served by the first NB. For instance, when the backhaul interface through which the first NB communicates with the core network becomes threshold highly loaded with communication traffic, the computing system could responsively impose a maximum cap on the number of the first-NB-served UEs that will be provided with secondary connectivity by one or more second NBs and/or on the number of secondary connections that will be established for UEs served by the first NB.

Abstract: A technique for Bluetooth wireless communication is described. According to one aspect of the technique, Bluetooth data from a data source is received in a first wireless device through an antenna and a Bluetooth radio frequency transceiver thereof via a Bluetooth connection with the data source. The Bluetooth data is used to generate a modulation signal according to a narrowband orthogonal multi-carrier modulation technology.

The described technique can be advantageously used for expanding the distance of Bluetooth wireless propagation of Bluetooth devices.

Abstract: A network switch using a search engine to generate chained table lookup requests. After the search engine executes a first lookup, the next-pass logic in the search engine uses the first lookup result and information in the master key to generate a second lookup key as well as other parts of a second lookup request. A next-pass crossbar routes the second lookup request to a target memory, and the search logic executes the second lookup. The first lookup request may originate from a processing engine coupled to the search engine. The first and the second lookup results, if any, can then be returned back to the processing engine for further processing or decision making. The chain of lookups can be configured by software by specifying various operational parameters of the processing engines and the next-pass logic, including specifying a key construction mode for the second lookup.
