Abstract: A system and method for collision avoidance within nodes of an Automatic Link Exchange (ALE) network establishes a handshake between transmitting and receiving nodes for a linked call over an assigned frequency band. The transmitting and receiving nodes mutually determine transmission and reception sub-channel vectors within the assigned frequency band, e.g., for calling and response. Before the linked call commences, and when other scanning stations of the ALE network dwell on the assigned frequency band, the transmitting and receiving nodes transmit collision avoidance protocol data units (PDU) identifying the nodes, the transmission and reception sub-channel vectors, and the duration of the linked call such that scanning nodes may prevent interference with the linked call by avoiding transmission over the identified sub-channels.

Abstract: Orthogonal Time Frequency Space (OTFS) is a novel modulation scheme with significant benefits for 5G systems. The fundamental theory behind OTFS is presented in this paper as well as its benefits. We start with a mathematical description of the doubly fading delay-Doppler channel and develop a modulation that is tailored to this channel. We model the time varying delay-Doppler channel in the time-frequency domain and derive a new domain (the OTFS domain) where we show that the channel is transformed to a time invariant one and all symbols see the same SNR. We explore aspects of the modulation like delay and Doppler resolution, and address design and implementation issues like multiplexing multiple users and evaluating complexity. Finally we present some performance results where we demonstrate the superiority of OTFS.

Abstract: Methods, systems, and devices for wireless communications are described for allocating additional random access channel (RACH) resources. A user equipment (UE) may transmit a random access request to a base station. The base station may respond to the random access request with a random access response or other signaling that indicates additional RACH resources for a second random access request. The UE may select a resource from the additional RACH resources to transmit the second random access request. The network may also configure additional RACH resources for peak times and may indicate the additional RACH resources to the UE. The UE may select a resource from the additional RACH resources or baseline RACH resources and may use the selected resource to transmit a random access request.

Abstract: An extended service-function chain (SFC) proxy is hosted on a network node and connected to a service path formed by one or more network nodes hosting a chain of service-functions applied to packets traversing the service path. The packets each include a service header having a service path identifier and a service index. A packet of a traffic flow destined for a service-function is received from the service path and sent to the service-function. An indication to offload the traffic flow is received from the service-function. The indication is stored in a flow table having entries each identifying a respective traffic flow. A subsequent packet of the traffic flow is received from the service path. The flow table is searched for the indication to offload the traffic flow. Upon finding the indication, the service-function is bypassed, and the subsequent packet is forwarded along the service path.
