Abstract:
A technique is provided for receiving, by a user device from a base station, a control signal indicating that base station-triggered reference signals will be transmitted to the user device, and receiving, by the user device, the base station-triggered reference signals on a set of time-frequency resources in at least one physical downlink control channel (PDCCH) search space.
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.
Abstract:
Various communication systems may benefit from the appropriate logging of measurements. For example, communication systems employing multimedia broadcast multicast service may benefit from logging multicast-broadcast single-frequency network measurements. A method can include logging, by a user equipment, a multicast-broadcast single-frequency network measurement corresponding to a logging period. The method can also include storing, at the time the multicast-broadcast single-frequency network measurement is made, cell measurement results.
Abstract:
Methods and apparatus, including computer program products, are provided for MBSFN measurements. In one aspect there is provided a method. The method may include receiving, by a user equipment, an indication of a monitoring requirement (202, 204) for at least one of an idle mode of operation at the user equipment or a connected mode of operation at the user equipment; receiving, by the user equipment, information (206) for one or more transmissions (MBMS) that are multicast or broadcast; and measuring, by the user equipment, the one or more transmissions (MBMS) that are multicast or broadcast, the measuring performed in accordance with the received information (206) and without regard to the indication of the monitoring requirement (202, 204) for at least one of the idle mode of operation or the connected mode of operation. Related apparatus, systems, methods, and articles are also described.
Abstract:
Various methods are provided for facilitating optimized access for efficient offloading in small cell deployments. One example method may comprise causing receiving an indication enabling direct access of one or more cells, causing access to be performed according to the indication of one or more cells that may be accessed, determine an availability of a small cell that fulfills conditions for direct access, changing to small cell if small cell meets conditions, and performing access to small cell if cell is changed and perform access to a macro cell if cell is not changed.
Abstract:
Methods and apparatus, including computer program products, are provided for measurement delivery. In some example embodiments, there is provided a method. The method may include receiving information to configure a user equipment to perform one or more measurements and to configure the user equipment to report, when requested by a network, the one or more measurements; receiving a request from the network to report the one or more measurements configured based on the received information; and reporting, in response to the request from the network, the one or more measurements to the network, without regard to measurement event reporting. Related apparatus, systems, methods, and articles are also described.
Abstract:
Various communication systems may benefit from synchronized physical layer reconfiguration among user equipment, macrocell and small cell in macrocell-assisted small cell deployments. A method may include dynamically changing a physical layer configuration of transmission of uplink control information in a network. The method may also include applying the dynamic change of the physical layer configuration between at least one user equipment and at least two transmitting devices The method may also include performing random access channel procedures for a physical layer reconfiguration between at least one user equipment and at least two transmitting devices.
Abstract:
Embodiments of the present disclosure relate to supporting network controlled measurement interruption ratio. In an aspect, a terminal device determines, based on at least one measurement requirement, a first interruption ratio. The first interruption ratio is different from a second interruption ratio acceptable by the network device. The terminal device transmits, to a network device, a first message requesting the network device to grant the first interruption ratio. By implementing the embodiments of the present disclosure, network controlled measurement interruption ratio can be supported and the negative impact caused by the interruptions could be reduced.
Abstract:
A user equipment (UE) may receive, from a network entity, a configuration of one or more candidate cells for switching to from a serving cell. The UE may receive, from the network entity, an indication to deactivate all transmission configuration indicator (TCI) states associated with one or more indicated cells. The UE may deactivate the all TCI states associated with the one or more indicated cells based at least in part on receiving the indication to deactivate the all TCI states. One or more of the one or more candidate cells or the serving cell may include the one or more indicated cells.
Abstract:
A first apparatus may be configured, over a serving cell, to indicate to a second apparatus controlling the operation of the serving cell, a suitability of a non-serving cell for one or more inter-cell purposes. For example, the first apparatus may receive from the second apparatus Layer 3, L3, measurement configuration information including a criterion for one or more first inter-cell purposes. When the first apparatus detects, based on performed L3 measurements of one or more reference signals in one or more non-serving cells that the criterion is met for L3 measurements of a first reference signal in a first non-serving cell, the first apparatus transmits a measurement report indicating that the first non-serving cell is a suitable cell for performing L1 measurements by the first apparatus for one or more second inter-cell purposes.
