A method for transmitting channel status information (csi) of downlink multi-carrier transmission includes generating the csi including at least one of a rank indicator (ri), a first precoding matrix index (pmi), a second pmi and a channel quality indicator (cqi) for one or more downlink carriers, the cqi being calculated based on precoding information determined by a combination of the first and second pmis, determining, when two or more csis collide with one another in one uplink subframe of one uplink carrier, a csi to be transmitted on the basis of priority, and transmitting the determined csi over a uplink channel. If a csi including an ri or a wideband first pmi collides with a csi including a wideband cqi or a subband cqi, the csi including a wideband cqi or a subband cqi has low priority and is dropped..

Method and transmitting a reference signal in a relay communication system
A method and apparatus for transmitting reference signals in a relay communication system are provided. The method transmits reference signals via a type 2 relay node in a relay communication system and includes a base station (bs) allocating a plurality of antenna ports in a mutually exclusive manner so that the antenna port of the bs and the antenna port of a peripheral relay node do not overlap each other, the bs and relay node transmitting reference signals to a user equipment (ue) via the corresponding antenna ports that are mutually exclusively allocated and the bs receiving channel state information from the ue to obtain channel state information between the bs and the ue and channel state information between the relay node and the ue..

Blacklisting techniques for detected set event evaluation
Blacklisting techniques for detected set event evaluation are described. In one embodiment, for example, user equipment (ue) may comprise at least one radio frequency (rf) transceiver, at least one rf antenna, and logic, at least a portion of which is in hardware, the logic to receive a measurement control message comprising a remotely-selected event evaluation blacklist (eeb) for a wireless communication frequency, determine whether a local eeb exists for the wireless communication frequency, and in response to a determination that a local eeb exists for the wireless communication frequency, replace the contents of the local eeb with the contents of the remotely-selected eeb.

Opportunistic power detection and antenna tuner measurement during concurrency
Methods implemented in a mobile communication device (e.g., a dual-sim-dual-active or multi-sim-multi-active communication device) for improving accuracy of radio-frequency (rf) output power measurements include opportunistically scheduling when a power detector takes rf output power measurements of a radio access technology (“rat”). In various embodiments, a processor of the mobile communication device may ensure that the power detector takes an accurate rf output power measurement of the rat by identifying an upcoming time window during which the rat's transmit power is not artificially reduced as a result of performing transmit blanking/zeroing or artificially increased by transmissions originating from one or more other rats operating on the device, and configuring or scheduling the power detector to take rf output power measurements of the rat during that upcoming time window.
Method and determining connection relationship between an antenna feeding port of base station and an antenna port
Embodiments of the present invention provide a method and apparatus for determining a connection relationship between an antenna feeding port of a base station and an antenna port. The method includes: receiving, via one antenna port, a signal sent by a base station, and acquiring the signal via a smart bias-tee in an antenna and a port of a remote control unit in the antenna, where the antenna port, the smart bias-tee, and the port of the remote control unit are in a one-to-one correspondence; determining, according to the smart bias-tee and the port of the remote control unit that acquire the signal, the antenna port that receives the signal; and sending, to the base station, identification information of the antenna port that receives the signal, and/or identification information of an antenna corresponding to the antenna port.

Otfs methods of data channel characterization and uses thereof
Fiber, cable, and wireless data channels are typically impaired by reflectors and other imperfections, producing a channel state with echoes and frequency shifts in data waveforms. Here, methods of using otfs pilot symbol waveform bursts to automatically produce a detailed 2d model of the channel state are presented.
