The present invention provides a method and a system for arranging base stations in a millimeter wave communication network. The method establishes a stochastic optimization framework for millimeter-wave base station deployment in the urban street geometry and provides a low-complexity user association arrangement which can well balance the workloads among BSs and reduce the outage probability by taking the time-varying nature of user equipments' positions and the susceptibility of millimeter-wave links to blockage effect into account. Compared with the state-of-the-art approaches, the present invention can effectively and efficiently reduce the outage probability in the long term.

The technology described herein reduces control-plane overloading by transferring UEs from the overloaded control plane to another available control plane. At a high level, the technology identifies when a control plane is overloaded, identifies other available control planes in a geographic area served by the overloaded control plane, and then identifies UEs for transfer using one or more criteria. Initially, a measure of control-plane performance for a control plane is received. Next, a determination is made that the control plane is overloaded by comparing the measure of control-plane performance to an overload threshold. When an overload condition exists for a control plane, then UEs with existing communication sessions using the control plane are identified for transfer.

Disclosed are methods, systems, apparatus, and computer programs for configuring packet loss rate (PLR) thresholds for UEs in a wireless communications network. In one aspect, a method includes receiving, by a UE connected to a wireless communications network, a packet loss rate (PLR) threshold configuration message from a node in the wireless communications network; determining, by the UE and based on the PLR threshold configuration message, a new PLR threshold configuration; and in response to determining the new PLR threshold configuration, selectively adjusting one or more configuration settings associated with a connection to the wireless communications network based on the new PLR threshold configuration.

In embodiments, apparatuses, methods, and storage media may be described for identifying subframes in a radio frame on which a UE may receive a Physical Downlink Control Channel (PDCCH) or enhanced PDCCH (ePDCCH) transmission. Specifically, the UE may receive multiple indications of uplink/downlink (UL/DL) subframe configurations and identify one or more subframes in which the UE may receive the PDCCH or ePDCCH transmission. The UE may then monitor one or more of the identified subframes and base discontinuous reception (DRX) timer functionality on one or more of the identified subframes.

A method, a computer-readable medium, and an apparatus are provided for wireless communication at a network node having a split bearer configuration with a user equipment (UE). The network node measures, at a primary node (MN) or a secondary node (SN), a data burst statistic for the network node, the data burst statistic being based on at least one of a burst level throughput or a packet loss measurement for a data burst between the UE and the MN based on a first bearer in the split bearer configuration or between the UE and the SN based on a second bearer in the split bearer configuration. The network node provides the data burst statistic from the network node to at least one of the MN or a core network component.

Various embodiments comprise systems, methods, mechanisms, and apparatus providing a traffic management function suitable for use at an intermediate Transmission Control Protocol (TCP) node (e.g., a cable modem) through which TCP uplink (UL) and downlink (DL) session traffic flows via respective linked UL and DL buffers is configured to manage ACK/NACK message insertion into the DL buffer to provide accelerated TCP UL packet size increases to so as to rapidly increase TCP UL data flow through the intermediate network node, and to provide constrained TCP UL packet size so as to rapidly decrease TCP UL data flow (apply backpressure) so as to avoid a buffer overflow condition.

Systems and methods are provided for adapting communication parameters to a variety of link conditions, traffic types and priorities. For example, WiFi transmission parameters (e.g. retry limit, AIFS, CW size, MCS order and/or CCA threshold) may be adapted to channel congestion levels, channel errors and/or traffic priority levels. Parameter adaptation may be coordinated across layers (e.g. between MAC and PHY layer parameters). Congestion levels may be detected, for example, using a smoothed queue size and/or channel busy time. Traffic may be transmitted using adapted parameters, such as reduced retry limits for a high congestion level and increased retry limits for priority traffic in response to channel error. Feedback may support parameter adaptation. For example, feedback may be provided by a receiver and/or within a sender, such as a sender MAC and/or PHY layer or a parameter adapter providing feedback (e.g. spoofed NACK packet) to a sender application, transport and/or network layer.

Disclosed are an overload control method in a wireless communication system and a device for the same. Specifically, a method by which a base station performs an overload control in a wireless communication system can include: a step of receiving an overload start message from a core network; a step of receiving a first radio resource control (RRC) message including a non-access stratum (NAS) message from user equipment (UE); and a step of transmitting an RRC connection release message, for instructing the release of an RRC connection, to the UE when an instruction for instructing data transmission through a control plane in the first RRC message is included.
