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: 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: 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.

Abstract: A logical interface is used to facilitate the exchange of information (START) between a first radio network and a second network. The logical interface is realized by utilizing the user plane of the core network architecture to transmit information from the first radio network to the second radio network. Once the information is received by the second radio network, the second radio network determines at least one threshold value, which is sent to a user equipment device in communication with the second radio network. Upon receiving the at least one threshold value, the user equipment device can make traffic routing decisions, based on the at least one threshold value and other network-related parameters.

Abstract: A logical interface is used to facilitate the exchange of information between a first radio network and a second network. The logical interface is realized by utilizing the control plane of the core network architecture to transmit information from the first radio network to the second radio network. Once the information is received by the second radio network, the second radio network determines at least one threshold value, which is sent to a user equipment device in communication with the second radio network. Upon receiving the at least one threshold value, the user equipment device can make traffic routing decisions, based on the at least one threshold value and other network-related parameters.

Abstract: The examples described herein provide for a Secondary Base Station (SeNB) Change procedure in a system configured to provide Dual Connectivity, where the SeNB Change procedure does not include the RACH procedure. As part of the SeNB Change procedure, a UE device generates a request that the Target Secondary base station (Target SeNB) is to send a Media Access Control (MAC) message to the UE device. In some examples, the request can be configured to specify a particular MAC Control Element that the Target SeNB should send in response to receiving the request. Upon receipt of the request, the Target SeNB transmits the requested MAC message to the UE device, along with TA information, if required. The UE device determines when the SeNB Change procedure has been completed, based at least partially on when the requested MAC message is received from the Target SeNB.

Abstract: In a communication method according to one embodiment, a first base station sets a WLAN (Wireless Local Area Network) mobility set that is a set of one or more WLAN identifiers to a user equipment. The first base station decides a handover of the user equipment to a second base station. The first base station includes, in a handover request message for the user equipment, an identifier of a WLAN termination device associated with the one or more WLAN identifiers. The first base station transmits the handover request message including the identifier of the WLAN termination device to the second base station.

Abstract: In a cellular communication system, a UE device being served by a serving communication station is instructed to transmit an uplink signal in accordance with an uplink signal configuration. The uplink signal configuration information is sent to a non-serving communication station in an inactive state where the non-serving communication station cannot provide wireless service. The uplink signal configuration information allows the non-serving communication station to configure its receiver to receive the up-link signal from the UE. Based, at least in part, on information pertaining to the uplink signal received by the non-serving communication station and then sent to the serving communication station, the serving communication station determines whether the UE device is sufficiently near to the non-serving communication station to receive wireless service from the non-serving communication station, in which case the non-serving communication station is activated.
