Abstract: Technologies for adaptively classifying network packets for quality of service (QoS) are provided herein. Adaptive classifiers track network packets transferred in data flows and network sessions, and apply various QoS classifications to the packets. An adaptive classifier can apply different QoS markings to packets in a data flow based on data flow metadata, such as the age of the data flow and/or the amount of data transmitted in the data flow. An adaptive classifier can assign various priority levels to network packets during different phases of a network session. Routers that receive the packets can prioritize transmission of the packets based on the applied QoS markings or assigned priority levels.
Abstract: Provided are a data encoding method and device, a storage medium, and a processor. The method includes: obtaining data to be sent; performing quasi-cyclic low-density parity check (LDPC) encoding on the data to be sent to obtain an LDPC codeword sequence, and interleaving the LDPC codeword sequence to obtain an interleaved LDPC codeword sequence; performing cyclic bit selection on the interleaved LDPC codeword sequence from a starting position to obtain a rate-matched codeword sequence, where the starting position is determined according to a predetermined parameter; and sending the rate-matched codeword sequence. The solution above resolves the problem in the related art of unstable transmission after performing quasi-cyclic LDPC encoding on data to be transmitted, and achieves stable transmission after the quasi-cyclic LDPC encoding.

Abstract: The present disclosure relates to a method and an apparatus for reducing or eliminating interferences between resource blocks in a transmitter and/or a receiver of a filter bank multicarrier system is provided. According to at least one embodiment, the method comprises performing discrete Fourier transform (DFT) on a data symbol vector to be transmitted thereby generating a DFT-spread data symbol vector, performing a cyclic shift operation on the DFT-spread data symbol vector to arrange a small magnitude element of the DFT-spread data symbol vector at an edge of a resource block allocated to the DFT-spread data symbol vector, and performing filter bank multicarrier (FBMC) modulation on a cyclically shifted DFT-spread data symbol vector.
Abstract: In one embodiment, a first wireless access point (AP) of a first basic service set (BSS) receives, from a second wireless AP of a second BSS, data indicative of an 802.11-based target wake time (TWT) schedule of a client of the second BSS. The first wireless AP identifies, from the receive data, a scheduled communication time of the client of the second BSS in the TWT schedule. The first wireless AP generates an 802.11-based TWT schedule for a client of the first BSS that avoids the scheduled communication time of the client of the second BSS. The first wireless AP sends the generated 802.11-based TWT schedule to the client of the first BSS, wherein the sent TWT schedule causes the client of the first BSS to wake from sleep at a scheduled wake time.

Abstract: Methods, apparatuses, systems, etc., directed to resource solicitation for Fog Radio Access Network (RAN) are disclosed herein. For some embodiments, a wireless transmit receive unit (WTRU) may receive a Fog-Resource Solicitation, for example included in a paging message, for joining a Fog Radio Access Network (RAN) platform (e.g., soliciting resources). The WTRU may accept or decline the Fog-Resource Solicitation, for example, based on any of the solicited resources and the WTRU status. In case the WTRU accepts the fog-Resource Solicitation, the WTRU may establish a connection to the RAN for indicating an acceptance of the Fog-Resource Solicitation. In case the WTRU declines the Fog-Resource Solicitation, the WTRU may ignore the Fog-Resource Solicitation or respond to the Fog-Resource Solicitation by establishing a connection to the RAN, indicating a declination of the solicitation. For some embodiments, a WTRU may trigger sending a RRC-Connection Release Request to e.g.
Abstract: A mobility management entity (MME) can enable overload control of data transmission via control plane in an evolved packet system (EPS), optimized for cellular internet of things (CIoT), by use of a control plane data backoff timer that suppresses the use of control plane for data transfer by a user equipment (UE) for the duration of the timer. For example, an MME sends a control plane data backoff timer to a UE that suppresses the use of control plane for data transfer for the duration of the timer. Alternatively, when an MME load reaches a threshold, an MME triggers an Overload Start message and sends it to the RAN node, so that the RAN node can restrict selecting this MME for UEs requiring data transfer using control plane CIoT optimization. The RAN node can reject these UEs and return a wait timer in an RRC Connection Release message.
