Abstract: A method for performing, by a first terminal, D2D communication in a wireless communication system, according to an embodiment of the present invention, the method comprising: receiving, from a second terminal, control information including information on future resources of the second terminal allocated to be used for transmission of the second terminal; and performing D2D transmission in consideration of the future resources of the second terminal, wherein the first terminal does not perform the D2D transmission in a resource in which a receipt power of the future resources of the second terminal is greater than a specific threshold.
Abstract: Disclosed are a method and an apparatus for channel quality estimation in consideration of interference control and coordinated communication in a cellular system. A base station receives an SRS transmitted by a terminal to thus measure received power, and then configures, for the terminal, a CSI process which may measure SINRs for base stations having higher SRS received power. If the terminal feeds back, to the base station, channel quality information for the configured CSI process, the base station determines an SINR and a MCS to be applied to data transmission in consideration of a received CQI and a CoMP transmission scheme, and applies the determined SINR and MCS to thus transmit data.
Abstract: The present invention provides a method, device, and system for adjusting a contention window size for performing channel access. The method includes: receiving uplink scheduling information on the uplink transmission including a new data indicator (NDI) associated with a specific subframe in a first uplink transmission burst; determining a contention window size based on the NDI; generating a random number N (N?0) in the determined contention window size based on the NDI associated with the specific subframe; and performing the uplink transmission on the specific cell after sensing a channel on the specific cell at least for N slots while the channel on the specific cell is idle. If the NDI is toggled, the contention window size is reset to a minimum value, and if the NDI is not toggled, the contention window size is increased to a next higher allowed value.

Abstract: Methods of upgrading a mesh network device reduce the amount of memory required on such devices. A network device may identify a neighbor network device in response to receiving a request to perform an upgrade, and send a message configured to cause the neighbor network device to function as a recovery node. The network device may then perform the upgrade without retaining a backup image in memory. If the neighbor network device determines that the upgrade failed based on messages not received from the mesh network device being upgraded, the neighbor network device may recover the network device being upgraded by providing a file corresponding to the upgrade. The neighbor network device may determine that the upgrade failed if no response is received to a challenge message or if no indication of success is received after a time expires.

The random access power control apparatus includes: a first calculating unit configured to, by using a pathloss estimated based on an synchronization signal/physical broadcast channel block and/or a channel state information reference signal (CSI-RS) currently selected by a UE, calculate transmission power used by the UE in transmitting random access preambles. Hence, the UE may be adapted to UE random access procedures in such complex scenarios as multiple beams.

Abstract: A battery-powered node within a wireless mesh network performs energy-aware packet routing based on multiple factors. The battery powered node computes, for a given link to an adjacent node, the energy needed to transmit a packet to the adjacent node. The battery-powered node also determines the amount of battery energy remaining in the adjacent node. Based on these two factors, the battery powered node computes a link cost associated with the link to the adjacent node. The battery-powered node performs a similar computation for all adjacent nodes and then forwards packets via these adjacent nodes based on the associated link costs. The battery-powered node also maintains a table of routes through adjacent nodes, and reroutes packets through different adjacent nodes in response to link failures.
