The present invention relates to an apparatus and method for filtering advertisements of a target device by using friendly jamming with a beamforming antenna to jam at least one advertisement channel in at least one specific sector of non-target devices. Thus, a master device can easily discover the advertisement of the target device in order to successfully connect to the target device. In addition, since the jamming is performed on advertisement channels only, data connection channels are not disturbed.

The method for acquiring a RAT of a serving cell includes: receiving RAT indication information from the relay device, wherein the RAT indication information indicates RAT information of the serving cell where the relay device is located; determining, based on the RAT indication information, a RAT type adopted by a base station to which the serving cell belongs; and communicating with the base station using the RAT appropriate to the RAT type adopted by the base station.

One embodiment of the present invention sets forth a technique for evaluating connections between nodes in a mesh network. The technique includes determining, at a first node, one or more first accumulated message success rates associated with transmitting messages from the first node to a target destination within the mesh network via an established parent node and with receiving messages from the target destination via the established parent node; determining, based on the one or more first accumulated message success rates, that a search for a different parent node should be performed; identifying a plurality of potential parent nodes; computing, for each potential parent node, one or more second accumulated message success rates associated with transmitting messages from the first node to a target destination within the mesh network via the potential parent node and with receiving messages from the target destination via the potential parent node; and based on the second accumulated message success rates, selecting a new parent node from the plurality of potential parent nodes or maintaining the established parent node

The application discloses a WiFi station and an associated passive scanning method, including receiving an RF signal within a specific frequency band to generate a baseband signal; detecting whether the baseband signal includes a first preamble corresponding to a first channel and generating a first detecting result accordingly; detecting whether the baseband signal includes a second preamble corresponding to a second channel and generating a second detecting result accordingly; according to the first detecting result and the second detecting result, determining to use a center frequency of the first channel or a center frequency of the second channel to perform frequency shifting on the baseband signal, to generate the frequency-shifted baseband signal.

One embodiment of the present invention sets forth a technique for evaluating connections between nodes in a mesh network. The technique includes listening, at a first node and across a plurality of listening windows, for one or more messages transmitted by a second node during a first period of time; determining a number of messages received by the first node during the first period of time; computing, based on the number of messages received by the first node, a received message success rate associated with a first connection between the first node and the second node, wherein the received message success rate indicates a probability of successfully receiving, at the first node, messages transmitted by the second node via the first connection; and computing, based on at least one message received during the first period of time, a transmitted message success rate associated with the first connection, wherein the transmitted message success rate indicates a probability of successfully transmitting messages from the first node to the second node via the first connection.

A method of transmitting uplink data is provided. The method includes establishing connections with a first serving cell and a second serving cell, determining, by a user equipment (UE), a time period for a device-to-device (D2D) discovery signal communication via the second serving cell, determining, by the UE and based on an uplink grant received via the first serving cell, a first subframe associated with an uplink signal to an evolved NodeB (eNB) associated with the first serving cell, and in response to determining that the first subframe overlaps in time with the time period, refraining from transmitting the uplink signal in the first subframe, and transmitting, based on a retransmission timing, the uplink signal.
