    Abstract: Methods and apparatus for using a first number of antennas at one base station, e.g., at a first CBSD, in combination with a second, e.g., lesser number of antennas at another base station to provide different wireless terminals communications channels with different channel conditions are described. A ‘relay mode’ of operation at the second base station facilitates communication of data from the first base station. In this way the second base station is used to relay data sent from the first base station while the UE perceives the data as having been sent over the air by the first base station. The channels from the first and second base stations operate together providing a composite channel that will have different channel conditions than would be possible using simply the antennas of the first base station. Differences in channels to different UEs facilitates transmission scheduling at the first base station.

    Abstract: The present invention relates to methods and apparatus for managing uplink resource grants in wireless networks. An exemplary method embodiment includes the steps of: communicating resource grants to individual customer premise equipment (CPE) devices, the resource grants including at least a first resource grant to a first CPE device and a second resource grant to a second CPE device, the first resource grant giving the first CPE device the right to use a first set of resource blocks on a recurring basis, said second resource grant giving the second CPE device the right to use a second set of resource blocks on a recurring basis; monitoring the use of resource blocks granted to the first and second CPE devices during a first period of time; using stored resource utilization information to determine resource grants which are to be shared by the first and second CPE device.

    Abstract: A network environment includes a repeater wireless station. The repeater wireless station receives a first wireless signal from a wireless base station. The repeater wireless station transmits a second wireless signal from the repeater wireless station. The second wireless signal is a reproduction of the first wireless signal. When transmitting the second wireless signal, the repeater wireless station controls a phase shift of the second wireless signal with respect to a timing of the received first wireless signal to reduce wireless interference in the network environment.

    Abstract: An aspect includes a method for use with a mobile communications device comprising a plurality of subscriber identification modules sharing a cache. The method includes a first subscriber identification module authenticating with and connecting to the network, followed by a second subscriber identification module authenticating with and connecting to the network. The method also includes, while the first subscriber identification module is requesting and receiving first data from the network and storing the first data in the cache, the second identification module requesting and receiving second data from the network and storing the second data in the cache. The method further includes an application executing on the device retrieving and processing at least a portion of the first and second data stored in the cache, while at least one of the first and second subscriber identification modules is storing additional data received from the network in the cache.
