摘要： An approach for providing interference measurements for device-to-device communication is disclosed. A logic generates a control signal to instruct a plurality of stations to perform measurement relating to interference or path loss by the stations. The logic then receives measurement information from the stations and determines, based on the measurement information, whether resources are to be scheduled to provide direct communication between two of the stations.

摘要： According to an embodiment, a method, apparatus, and computer readable medium can provide an efficient mechanism to improve data rates of nodes suffering high interference without sacrificing performance of nodes that do not need interference-free channels to communicate. A node can receive two or more RTS packets and identify the RTS packet corresponding to its own cell, as well as RTS packets belonging to interferers. Based on the interference level estimated from the RTS packets, the node can decide if the channel needs to be interference-free for the intended transmission or if the current level of interference is acceptable. According to the embodiment, there can be two or more different types of CTS packets. A node can decide which type of CTS packet to transmit based on the information, signal level, interference level, or a combination therein, of at least two RTS channels, and based on measurements performed on these RTS channels, or other channels.

摘要： A first parameter such as an indicator of modulation and coding scheme MCS for a first shared channel SCH codeword and a second parameter for a second SCH codeword are determined. From a locally stored mapping rule a bit sequence that explicitly indicates the first parameter and that implicitly indicates the second parameter is chosen, and a first control channel CCH codeword is transmitted with the explicit bit sequence that explicitly indicates the first parameter for the first SCH codeword and a second CCH codeword is sent companion to the first CCH codeword, wherein the second parameter for the second SCH codeword is implicitly indicated by the explicit bit sequence of the first CCH codeword. The receiving party determines the second parameter by its own locally stored mapping rule, and an indicator in each CCH codeword may be used to inform the receiver that the two (or more) CCH codewords are associated with one another and to use its mapping rule to determine the second parameter.

摘要： In a MIMO delay spread (OFDM) system or a MIMO single carrier (non-OFDM) system wherein a transmitter transmits signals to a receiver through multipath fading channels, an equivalent frequency-domain MIMO multipath channel matrix is used to estimate the maximum mutual information regarding the relationship between transmitted signals and received signals. It is possible to compute the upper bound of the maximum mutual information at least based on the total energy of all resolvable paths in the fading channels. The upper bound or the changes in the upper bound can be used to adjust the transmission parameters used in data transmission. The transmission parameters include the modulation order in the modulation process, the code rate and the puncturing rate.
