    Abstract: Methods, apparatuses, and computer program products are disclosed for contention based shared preconfigured uplink resource configuration. An example method includes receiving an assignment of contention based shared preconfigured uplink resources; receiving an assignment of a common radio network temporary identifier for monitoring downlink control information indicating a negative acknowledgement for contention based shared transmission, and a dedicated radio network temporary identifier for monitoring downlink control information indicating an acknowledgement of transmission of uplink data; transmitting the uplink data using a physical uplink shared channel allocated for the contention based shared preconfigured uplink resource transmission; in response to the downlink control information indicating the negative acknowledgement and uplink grants for multiple physical uplink shared channel resources, retransmitting the uplink data on a selected one of the received uplink grants; and in response to the downlink control information indicating the acknowledgment, not retransmitting the uplink data.

    Abstract: A UE in a wireless network receives measurement configuration for group(s) of cells wherein the measurement configuration is for positioning measurements of the UE using signals from base station(s). The UE receives criteria based on the measurement configuration for the UE to trigger report(s) for the group(s) of cells. The UE performs, using at least the measurement configuration, positioning measurements of the group(s) of cells and sends a report that is triggered based at least on the criteria. A network element sends the measurement configuration for the group(s) of cells to the UE. The network element sends the criteria based on the measurement configuration for the UE to trigger the report(s) for the one or more groups of cells. The network element receives a report from the UE that was triggered based at least on the criteria. Methods, software, computer program products, and apparatus are disclosed.

    Abstract: A method for calibrating timing errors to improve positioning accuracy includes receiving, from a network element, calibration configuration information for communicating at least one positioning reference signal; communicating, during a positioning session and on the basis of the received calibration configuration information, a first positioning reference signal according to a first positioning reference signal pattern; and communicating, during the positioning session or during another positioning session and on the basis of the received calibration configuration information, a second positioning reference signal according to a second positioning reference signal pattern, wherein the second number of frequency resource elements is smaller than the first number of frequency resource elements and/or wherein the second number of time resource elements is greater than the first number of time resource elements.

    Abstract: According to an example embodiment, a method may include receiving, by a user equipment from a base station associated with a cell, control information assigning a subframe as a preconfigured uplink resource (PUR) subframe for the user equipment, the preconfigured uplink resource (PUR) subframe including an extended cyclic prefix, the control information indicating resources allocated to the user equipment for uplink transmission within the preconfigured uplink resource (PUR) subframe, wherein one or more other subframes for use by the user equipment include a normal cyclic prefix that is shorter in time than the extended cyclic prefix of the preconfigured uplink resource (PUR) subframe; and transmitting, by the user equipment, data via the resources allocated to the user equipment within the preconfigured uplink resource (PUR) subframe.
