摘要： Handover procedures and a collection of new handover MAC management messages are provided for a wireless mobile multi-bop relay (MMR) network. The types of handovers supported include macro diversity handover (MDHO) and fast access station switching (FASS). The handover procedures for these two types of handover and the MAC messages are described for nine main classes of network topologies. The nine classes of topology are further classified into to main categories, namely, intra multi-hop base station (MR-BS), when and where the handover is in the MMR cell, and inter MR-BS handover, when and where the handover is between two different MMR cells.

摘要： A method and system generating signal to select a subset of antennas from a set of antennas to transmit user data in a wireless communication system. User data are transmitted during a first transmission time intervals (TTI) using a first subset of antennas. Pilot tones are transmitted during a second TTI using a second subset of antennas. Corresponding channels are estimated for the first subset of antennas and the second subset of antennas from the user data and the pilot tones. Then, based on the estimating, an optimal subset of antenna is selected from the first subset of antennas and the second subset of antennas to transmit the user data during a sequent TTI, and in which the selecting is performed adaptively.

摘要： The embodiments of the invention provide a method for selecting antennas for date transmission in a wireless communication network including user equipment (UE). The network is assigned a band of frequencies, wherein the band is partitioned into at least one set of subbands of the band according to a sounding reference signal (SRS) band-width configuration in a form of a code-tree having a plurality levels and each level is associated with a partition coefficient. The UE is configured to transmit frequency-hopped SRS on the set of sub-bands using subsets of the set of antennas. First, the method determines if a number of subbands in the set of the sub-bands is odd or even based on the SRS bandwidth configuration, and selects a particular subset of the antennas according to whether the number is odd or even. Then, the SRS is transmitted from the particular subset of the antennas.

摘要： A wireless sensor network includes an initial set of anchors at known locations, and a set of sensors at unknown locations. Ranges, from each sensor to at least three of the anchors, determine a position, an anchor ranging weight, and an anchor position weight. For each anchor, the anchor ranging weight and the anchor position weight form a combined weight. A weighted least square (WLS) function for the positions and the combined weights is minimized to determine a position of the sensor, and a sensor position weight. The sensor is identified as being a member of a set of candidate anchor nodes, and the candidate anchor node with a largest sensor position weight is selected to be transformed to another anchor to minimize propagation of errors in the positions of the set of sensors.
