Publication number: 20200045595Abstract: 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.Type: ApplicationFiled: October 10, 2017Publication date: February 6, 2020Inventor: David COMSTOCK

Patent number: 10531378Abstract: 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 uplink 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.Type: GrantFiled: September 29, 2014Date of Patent: January 7, 2020Assignee: Kyocera CorporationInventor: David Comstock

Publication number: 20190174372Abstract: 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.Type: ApplicationFiled: August 10, 2017Publication date: June 6, 2019Applicant: Kyocera CorporationInventor: David COMSTOCK

Publication number: 20190150047Abstract: 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.Type: ApplicationFiled: January 17, 2019Publication date: May 16, 2019Inventor: David COMSTOCK

Publication number: 20180324655Abstract: 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.Type: ApplicationFiled: November 3, 2016Publication date: November 8, 2018Inventor: David COMSTOCK
