One of the embodiments of the present invention relates to a method for rank adaptation at a base station. The method comprises performing, during a rank sounding time interval, data transmission for a user equipment by using a sounding rank. The sounding rank is different from a transmission rank that is used in a transmission time interval immediately prior to the rank sounding time interval. The method further comprises determining whether spectrum efficiency for the user equipment under the condition of using the sounding rank is better than spectrum efficiency under the condition of using the transmission rank; and adjusting, in response to a positive result obtained from the determining step, the transmission rank to the sounding rank so as to be used during a transmission time interval immediately next to the rank sounding time interval. The present invention also relates to corresponding base station device.

A data distribution server and terminals measure a communication status with other devices. Based on measurement results of the communication status, the data distribution server categorizes the terminals as “trunk” or “branch”, notifies the terminals of categorization results, notifies the terminals of selection of a relay path through which data can be distributed to all relay terminals by relaying the data between “trunks”, and instructs a “trunk” terminal to relay the data through the relay path. When notified that the terminal itself is a “trunk”, each of the terminals relays the data based on an instruction from the data distribution server. When notified by the data distribution server that the terminal itself is a “branch”, each of the terminals receives the data distributed from the data distribution server or the “trunk”.

A shared spectrum system may perform operations including retrieving a plurality of parameters for one or more high-priority users in the wireless network; computing, based on the retrieved parameters, a plurality of interference-to-noise power ratio (I/N) contour values; storing the plurality of I/N contour values in a database; receiving, from the RLAN in the wireless network, a request for channel availability, wherein the received request includes at least a first value; extracting, based on the first value in the request for channel availability, I/N contour values from the database exceeding a threshold value; determining, based on the extracted I/N contour values, available frequency information corresponding to the received request for channel availability; and transmitting a channel availability response comprising the available frequency information.

Embodiments herein relate to a receiving device (11) and a method performed by the receiving device (11) performed by a receiving device (11) for communicating in a wireless communication network (1). The receiving device 11 attempts to detect a scheduling assignment from a transmitting device (10) based on information regarding one or more radio resources previously used by the transmitting device (10) for transmitting data to the receiving device (11) within the wireless communication network (1). When not detecting the scheduling assignment from the transmitting device (10), the receiving device (11) assumes that a transmission of data from the transmitting device (10) is scheduled on the one or more radio resources previously used by the transmitting device (10). The receiving device communicates within the wireless communication network (1) based on the assumption.
