Abstract: In a cellular communication system, a coverage transition Is performed where a compensation service area is expanded to cover an energy saving service area and the energy saving service area is deactivated The coverage transition is managed by transferring user equipment devices (UE devices) from an energy saving service area to a transition service area that at least partially overlaps with the energy saving service area. The UE devices may be transferred using a handover procedure between communication stations where each UE device is assigned communication frequencies for communication with the transition communication station that are not used by the energy saving communication station or the compensation service area, thereby avoiding, or at least minimizing, interference. After all UE devices are transferred from the energy saving service area, the communication stations are configured to deactivate the energy saving service area and to expand the compensation service area to cover the energy saving service area.

Abstract: In order to perform a RACH-less handover from a source base station to a target base station, a UE device generates a request that the target base station is to send a Media Access Control (MAC) message to the UE device. The request can be sent with a Radio Resource Control (RRC) Connection Reconfiguration Complete message. Alternatively, an RRC message sent from a UE device functions as an implicit request that the target base station is to send a MAC message to the UE device. The request can also be configured to specify a particular MAC Control Element that the target base station should send. The target base station transmits the requested MAC message, along with TA information, if required. The UE device determines when the handover has been completed, based at least partially on when the requested MAC message is received from the target base station.

Abstract: In the systems and methods described herein, the 3GPP RAN determines the thresholds that will be provided to the UE devices to facilitate steering traffic between radio networks. More specifically, an eNB of the 3GPP RAN determines the network-related parameter threshold values based, at least partially, on an indication that all or a portion of user data traffic of one or more UE devices is to be handed over from another network (e.g., WLAN). For example, based on the indication that all or a portion of user data traffic of one or more UE devices is to be handed over from another network, the eNB may determine that either more or less traffic should be offloaded to the WLAN. The eNB can modify the network-related parameter threshold values that are being sent to the one or more UE devices so that the level of traffic being offloaded can be appropriately increased or decreased.

Abstract: A smart headset communicates through the cellular transceiver with a cellular network when the smart headset in a first mode and communicates through a Bluetooth transceiver with a smart handset when the smart headset is in a second mode. A controller of the smart headset is configured to place the smart headset in the first mode when the smart handset is determined to be farther than a maximum proximity from the smart headset and configured to place the headset in the second mode when the smart handset is determined to be within the maximum proximity to the smart headset.

Abstract: Systems and methods for facilitating the mitigation of interference in the uplink of a small cell caused by macrocell user equipment in the case where the macrocell cannot identify the interfering macrocell user equipment because the user equipment cannot detect and report the small cell's downlink due to the small cell's uplink/downlink coverage imbalance. In an embodiment, the small cell provides the macrocell with a notification of the interference, the configuration information about its Physical Random Access Channel (PRACH), and a plurality of unique preambles and transmission times for non-contention-based transmissions on the small cell's PRACH. The macrocell orders each of one or a plurality of macrocell user equipment to transmit one of the unique preambles on the small cell's PRACH. The small cell reports to the macrocell the detected preamble transmissions, which allows the macrocell to identify interfering user equipment and perform corrective actions.

Abstract: Communication equipment communicates in a licensed frequency band using a licensed band physical channel structure (licensed structure) and communicates in an unlicensed frequency communication band using an unlicensed band physical channel structure (unlicensed structure) where the unlicensed structure includes at least the same symbol times and subcarrier frequency divisions as in the licensed structure. The symbol times and subcarriers form a plurality of time-frequency communication resource elements. A set of symbol times and subcarrier frequency divisions form a licensed reference subset of communication resource elements that are allocated for reference signal transmission in the licensed structure. The same set of symbol times and subcarrier frequency divisions form an unlicensed reference subset of communication resource elements that are allocated for reference signal transmission in the unlicensed structure.

Abstract: A UE is configured to perform Radio Link Monitoring (RLM) with a first Coverage Enhancement (CE) configuration that provides a first CE level. The first RLM configuration associated with the first CE configuration has a first radio-link-quality-improving threshold value that corresponds with a third distance from a base station that is closer to the base station than a second distance associated with an in-sync radio link quality threshold value associated with a first RLM configuration. The first RLM configuration also has a first radio-link-quality-improving-cancellation threshold value that corresponds with a fourth distance from the base station that is located farther from the base station than the third distance and closer to the base station than the first distance. If conditions are satisfied, the base station reconfigures the UE with a second RLM configuration and a second CE configuration having a second CE level lower than the first CE level.

Abstract: RACH-less handovers can be used to reduce the additional time required to complete the RACH procedure when the Timing Advance (TA) must be determined as part of the handover procedure. In order to facilitate a RACH-less handover, the source base station informs the target base station of a radio transmission configuration that will be used by the UE device to transmit uplink signals to the source base station, and the source base station configures the UE device in accordance with the radio transmission configuration. The UE device transmits uplink signals to the source base station using the specified radio transmission configuration, and the target base station receives the uplink signals. The UE device transmits these uplink signals to the source base station before the handover procedure is initiated. The target base station calculates the TA, based on the uplink signals, which can be signaled to the UE device in a handover command.
