Abstract: Embodiments of the present disclosure relate to a method for confirming uplink semi-persistent scheduling deactivation and a terminal device. In example embodiments, an indication of uplink semi-persistent scheduling deactivation is received from a base station while the terminal device stores data available for uplink transmission. Then, confirmation of the deactivation is sent to the base station. Such confirmation of the deactivation may notify the base station that the terminal device has received the indication of the uplink semi-persistent scheduling deactivation and further that the uplink semi-persistent scheduling will be deactivated at the terminal device.

Abstract: Improved systems and techniques for communication in an environment in which muting of resources is used to avoid interference between cells. If a cell, represented by a macro eNB for example, is muting resources, those resources can be made available, under appropriate conditions, to user devices, such as UEs, engaging in device to device communication. Allocation of muted resources to D2D UEs can be based on meeting of conditions, such as that the D2D UEs be outside of a specified proximity to a cell, such as a small cell, using the resources, or that the D2D UEs transmit at less than a specified power. The UEs may take measurements to determine if the conditions are met and report the measurements to their base stations, which then determine whether to allocate the muted resources and configure the UEs with resource allocation information.

Abstract: The example embodiments of the invention provide at least a method and apparatus to measure, by a user equipment, a communication quality with at least one measured cell of a communication node while the user equipment is in an idle or inactive state; upon the user equipment transitioning to a connected state, determine by the user equipment that the communication quality with the at least one measured cell is larger than a threshold; and transmit information comprising a measurement report from the user equipment to a network equipment that the at least one measured cell meets the threshold for the network equipment to signal the user equipment to configure communication with the at least one measured cell without further measurements from the user equipment. Further, a method and apparatus to receive by a network equipment information comprising a measurement report from a user equipment which is waking from an idle or inactive state and seeking access to a serving cell communication, wherein the measurement report comprises an identification of a cell which met a communication quality threshold with the user equipment while the user equipment was in the idle or inactive state; compare the measurement report received by the network equipment from the user equipment to a predetermined threshold value, wherein based on the comparing the network equipment is caused to configure communication with the cell without further measurements from the user equipment, wherein based on the comparing the network equipment is caused to configure communication with the cell without further measurements from the user equipment; and send a signal from the network equipment to the user equipment with instructions for the user equipment to configure communication with the cell without further measurements from the user equipment.

Abstract: Various communication systems may benefit from improved handover techniques. For example, a communication system may allow for an autonomous user equipment handover operation in a licensed or unlicensed spectrum. A method may include receiving a measurement condition at a user equipment. The measurement condition may include a maximum duration of time for sending a message to a base station of a source cell. The message may inform the base station of the source cell that an autonomous handover is initiated. The method may also include initiating the sending of the message to the base station of the source cell during the duration of time Tamer to indicate of the measurement condition. In addition, the method may include commencing the autonomous handover after the duration of time of the measurement condition has expired or upon successful transmission of the message to the base station of the source cell.

Abstract: Systems, methods, apparatuses, and computer program products for enhancing the setup of carrier aggregation (or dual connectivity or multi connectivity or stand-alone LTE/LTE-like on unlicensed band or LAA or LTE-WLAN aggregation) from IDLE mode (or semi-idle or semi-connected or suspended state) are provided. One method includes providing an indication, to at least one UE, of (or configuring the UE with) potential inter-frequency carriers that the UE should measure during IDLE mode (or during semi-idle or semi-connected or suspended state) for potential SCells. The method may further include during or after RRC connection establishment, receiving an indication from the at least one UE that it has inter-frequency carrier(s) and/or SCell measurement results available, and based on the received measurement results, configuring carrier aggregation (or dual connectivity or multi connectivity or LAA or LTE-WLAN aggregation) without further measurements and activating the SCell.
