Abstract: A base station identifies received backhaul traffic including IP packets based on whether or not the reception was via a secure tunnel, e.g., an IPsec tunnel. Recovered data, e.g., an IP packet from an IPsec tunnel, is associated with an IPsec identifier having a value indicating that the packet came from an IPsec tunnel. Data, e.g., recovered IP packets, associated with an identifier indicating receipt via an IPsec tunnel are stored in a first transmission buffer, e.g., a high priority transmission buffer, while other recovered IP packets which were not received via an IPsec tunnel are stored in a second transmission buffer corresponding to a lower, e.g., normal, transmission priority. A downlink transmission scheduler, e.g. an MAC or frame scheduler, schedules transmission of frames includes IP packet data from both buffers, with data in the first buffer being given higher priority to reduce latency with regard to the IPsec traffic.

Abstract: A communication management resource partitions allocated wireless bandwidth into a first portion (such as first virtual bandwidth or first bandwidth part) and a second portion (such as virtual bandwidth or second bandwidth part). The communication management resource determines wireless interference associated with transmission of first wireless communications over the different bandwidth portions such as from a wireless base station to multiple communication devices while in a first mode. Depending on the wireless interference determined during the first mode, the communication management resource controls conveyance of second wireless communications over the allocated wireless bandwidth to the multiple communication devices in a second mode. In one instance, the communication management system operates one or more communication devices in a device-to-device mode to alleviate wireless interference associated with use of the allocated wireless bandwidth.

Abstract: In certain embodiments, a (e.g., 5G) wireless network has a (e.g., CBSD) base station and any suitable number of instances of user equipment (UE). For each group of one or more UEs, one of the UEs is designated as a primary UE that stores UE context information for the other (secondary) UEs in the UE group. To connect to a secondary UE, the base station can retrieve the UE context information from the secondary UE's associated primary UE without having to retrieve the secondary UE's context information from the core network, thereby reducing backbone bandwidth usage and delays in connecting the secondary UE, especially when many secondary UE request connections within a short time interval.

Abstract: In some embodiments, a wireless device (e.g., a cell phone) has a transceiver, a processor, and a memory. The processor store periodic downlink (DL) data received from the transceiver in a periodic DL buffer in the memory, aperiodic DL data received from the transceiver in an aperiodic DL buffer in the memory, periodic uplink (UL) data in a periodic UL buffer in the memory, and aperiodic UL data in an aperiodic UL buffer in the memory. The processor determines in what order to handle the stored data in the periodic and aperiodic DL and UL buffers and handles the stored data in the determined order.

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.
