摘要： A system and method of coordinating scheduling in a wireless communication system are described herein. In one aspect, user equipments determine one or more cells that interfere with communications received by the user equipments. The user equipment may determine particular information about the interfering cells, including a metric function based on the precoding matrix used by the interfering cell. The user equipment may transmit this information to the interfering cell in order to coordinate the use of precoding matrices between cells.

摘要： Techniques for determining time of arrivals (TOAs) of signals in a wireless communication network are described. Each cell may transmit (i) synchronization signals on a set of contiguous subcarriers in the center portion of the system bandwidth and (ii) reference signals on different sets of non-contiguous subcarriers distributed across the system bandwidth. A UE may determine TOA for a cell based on multiple signals transmitted on different sets of subcarriers. The UE may perform correlation for a first signal (e.g., a synchronization signal) from the cell to obtain first correlation results for different time offsets. The UE may perform correlation for a second signal (e.g., a reference signal) from the cell to obtain second correlation results for different time offsets. The UE may combine the first and second correlation results and may determine the TOA for the cell based on the combined correlation results.

摘要： Positions of non-reference wireless transceivers to be added to a wireless communication network are determined as follows. Each non-reference wireless transceiver performs measurements of times of arrival (TO A) of signals transmitted by other non-reference wireless transceivers, as well as reference wireless transceivers. Thereafter, time difference of arrival (TDOA) values are computed from at least two types of pairs of measurements as follows: (a) unknown-unknown TDOA values are obtained as differences between TOA measurements of signals transmitted by non- reference wireless transceivers and (b) unknown-known TDOA values are obtained as differences between a TOA measurement of a signal transmitted by a non-reference wireless transceiver and another TOA measurement of another signal transmitted by a reference wireless transceiver. Both types of TDOA values are used to solve simultaneous equations to identify the positions of the non-reference wireless transceivers and optionally times of transmission of the signals by the non-reference wireless transceivers.

摘要： A system and method of coordinating scheduling in a wireless communication system are described herein. In one aspect, cells receive information regarding one or more precoding matrices from user equipments. The information may include a request from an user equipment that the cell not use a particular precoding matrix for communications. The cell may determine whether restricting usage of the precoding matrix for communication improves overall communication in the wireless communication system by performing pair-wise comparisons of utility based on usage and restriction of the precoding matrix. The cell may further resolve conflicts that arise between several cells based on the granting of restriction of the precoding matrix.
