    Abstract: In LTE Random Access Channel (RACH) mechanism, devices use slotted ALOHA based protocol for RACH message exchange. During these messages exchange, if a device does not get a response from a base-station (BS), the device assumes that it is not able to reach base station due to insufficient transmission power and increases transmit power to reach to the base station. However, at higher density most of requests are lost due to collision. In existing RACH procedure, device unnecessarily ramps power in next RACH process which leads to power wastage in already resource constrained device. When there is failure of reception of RACH process, the present disclosure computes time delays (TD) based on a RSSI value obtained from a message transmitted by the BS, and initiates RACH process accordingly. The embodiments further enable requests transmission from device to BS by ramping power of the devices based on the computed TD.

    Abstract: The present application provides a method and system for sharing of unlicensed spectrum. The disclosed method and system when implement improves the spectral efficiency of LTE users and also improves the overall performance of LAA and Wi-Fi users. A BS senses the channel for any ongoing transmissions for a CCA period which is equal to DIFS time period of Wi-Fi. If the channel is busy (CCA-busy), it enters into back-off stage by selecting a uniform random number from [0, C0−1] as the back-off counter, where C0 is the fixed congestion window size. If the channel is free for a CCA period (CCA-idle), the back-off counter gets decremented by unity until it reaches zero. Once the back-off counter reaches zero, LAA again senses and schedules its down-link transmissions for a maximum channel occupancy period, provided the channel is free.

    Abstract: System(s) and method(s) for designing a network of one or more entities in an enterprise is disclosed. A design type along with configurable design parameters is selected from a list of designs. Requirements associated with design of entities are collected from the users. The requirements and configurable design parameters are analyzed to obtain analysis results. Based on at least one of a layer-wise requirement and distribution or a zone-wise requirement and distribution, network devices and modules associated with the entities are determined. One or more designs are generated for the network of entities based on the layer-wise requirement and distribution or the zone-wise requirement and distribution of network devices and modules associated with the entities in the enterprise.
