Abstract: Methods and apparatus for providing data services to devices at a customer premises. An exemplary method embodiment includes the steps of: switching from a first mode of operation to a second mode of operation with respect to providing data services to a user equipment device located at a customer premises upon detection of a first condition at the customer premises by a wireless base station; receiving, after switching into the second mode of operation, at the wireless base station a first data service request from the user equipment device; transmitting, in response to the first data service request, one or more data packets of a first data packet stream to the user equipment device via a first transmission path and transmitting one or more additional data packets of the first packet stream to the user equipment device via a second transmission path.

Abstract: Methods and systems for citizens broadband radio service (CBRS) interference management using dual subscriber identification module (SIM) devices are described. The method includes assigning a physical cell identity (PCI) to each CBRS device (CBSD) granted unlicensed spectrum by a spectrum access system (SAS). Each spectrum granted CBSD may exchange PCIs with neighbor spectrum granted CBSDs to resolve PCIs and maintains a PCI table. A dual SIM device may be connected to a CBSD via a first SIM. Each spectrum granted CBSD having a connected dual SIM device reports a number of PCIs detected by the dual SIM device(s). A SAS designated dual SIM device may use a second SIM to measure power values of PCIs detected by the designated dual SIM device which are absent from a provided PCI table. The measured power values may be used by the SAS to make cluster interference decisions.

Abstract: Methods, apparatus, and systems for using multiple antennas located in Citizens Broadcast Radio Service Devices (CBSDs) to communicate with a user equipment device. An exemplary method embodiment includes the steps of: (i) receiving by a macro base station a first set of data to be transmitted to a user equipment device (UE), (iii) dividing by the macro base station said first set of data into a plurality of N data blocks, and (iv) communicating by the macro base station to each of a plurality of different Citizens Broadband Radio Service Devices (CBSDs) one or more different ones of said plurality of N data blocks; and (v) operating the plurality of CBSDs to transmit the one or more data blocks which they receive from the macro base station to the UE. In various embodiments, the macro base station also transmits one or more of the N data blocks to the UE.

Abstract: Methods and apparatus for managing spectrum in a CBRS network to provide services to user equipment devices located at a customer's premises. In various embodiments, the customer premises has no landline connection. An exemplary method embodiment includes the steps of: receiving, by the CBRS CPE base station, over the air from each of a plurality of Citizens Broadband Radio Service Fixed Wireless Access (CBRS FWA) tower base stations a reference signal; selecting, based on the strength of each of the received reference signals, a primary CBRS FWA tower base station from the plurality of CBRS FWA tower base stations; establishing, by the CBRS CPE base station, a wireless communications link connection with the CBRS FWA tower base station selected as the primary CBRS FWA tower base station; reserving, by the CBRS CPE base station, an amount of spectrum for communicating with one or more auxiliary CBRS FWA tower base stations.

Abstract: Methods and apparatus for estimating a Citizens Broadband Radio Service Device's (CBSD's) coverage area using user equipment (UE) timing advance and/or power headroom information and allocating resources based on the estimate. In an exemplary method embodiment a Spectrum Access System: (i) receives, from a CBSD, user equipment (UE) information including at least one of timing advance or power headroom information for one or more UEs in communication with the CBSD; (ii) estimates, based on the received first UE information, a first CBSD coverage area; and (iii) makes a first resource allocation to the CBSD based on the estimated CBSD coverage area, the first resource allocation including an allocation of at least one of a frequency bandwidth allocation or transmission power allocation to the CBSD.
