Abstract: A user equipment, UE, (14) and a radio network node (12) can perform multiple input multiple output, MIMO, communication. The UE determines a precoder (50, 54) used in the radio network node for transmitting signals from multiple transmit antennas to the UE. Based on the determined precoder used, the UE determines receiver parameters (22, 60A, 60B) for receiving MIMO signals from the radio network node, and configures the UE to receive MIMO signals from the radio network node in accordance with the determined receiver parameters. The radio network node may provide information for transmission to the UE indicating the precoder used in the radio network node to permit the UE to determine a receiver configuration for receiving MIMO signals based on the determined precoder used by the radio network node.

Abstract: Techniques for using user equipment, UE, activity information, e.g., by a network node in a communications network are described. The network node can obtain the UE activity information, i.e., information associated with at least one of transmission activity and reception activity for a UE, and then use the UE activity information to configure a positioning function. Some examples of the positioning function are positioning method selection, measurement configuration and assistance data provisioning, reserving positioning resources, stopping the positioning session, delaying handover of the UE, deciding on a position session organization such as number of parallel measurements to be performed, and estimating an impact on battery lifetime.

Abstract: A user equipment (UE) performs measurements on a serving cell and at least one neighbor cell in a heterogeneous wireless communications network that includes one or more higher power radio network nodes operating near one or more lower power radio network nodes. The UE acquires enhanced neighbor cell information (eNCI) including at least subframe information and determines an allowed set of one or more subframes during which the UE may make downlink and/or uplink measurements for at least one cell in the heterogeneous network. A network node in the heterogeneous network generates the eNCI, from which the UE may determine the allowed set of radio transmission subframes, and provides the eNCI for the UE to coordinate the UE measurements on the at least one cell during one or more of the allowed subframes.

Abstract: The invention relates to methods and devices for supporting configuration of a measurement gap pattern for a user equipment (91) requiring measurement gaps for performing an inter-frequency measurement. A radio network node (81) receives an indication (85) from the user equipment (91) that the user equipment (91) is going to perform an inter-frequency measurement for positioning, which inter-frequency measurement requires measurement gaps. The radio network node (81) may determine a measurement gap pattern for performing the inter-frequency measurement and may signal, to the user equipment (91), information (86) to initiate use of the determined measurement gap pattern in the user equipment (91). Alternatively the user equipment (91) configures the measurement gap pattern itself based on a set of pre-defined rules.

Abstract: Mobility parameters, such as those used in handoff decisions, are based on the speed of User Equipment (UE) (10), measured at two points. UE speed estimates are taken at both the UE (10) and base station (12), and the two speeds compared. If the speeds match (or differ by less than a predetermined amount), one or more mobility parameters are adapted based on the UE speed. These parameters may include time to trigger (TTT), time to satisfy (TTS), measurement time, forgetting factor, β, measurement period (Tm), handover prohibit timer, MeasurementReportingmargin, HOmargin, hysteresis, and the like. The UE speed comparison may be performed at the UE (10) or at the base station (12). In one embodiment, a plurality of UE speed ranges are defined (e.g., low, medium, high), with corresponding mobility parameter values associated with each range.

Abstract translation: 移动性参数，如用于切换决策的参数，是基于在两点测量的用户设备（UE）（10）的速度。 在UE（10）和基站（12）两者都进行UE速度估计，并且比较两个速度。 如果速度匹配（或差别小于预定量），则基于UE速度来适配一个或多个移动性参数。 这些参数可以包括触发时间（TTT），满足时间（TTS），测量时间，遗忘因子，测量周期（Tm），切换禁止定时器，测量报告率，停留时间，滞后等。 UE速度比较可以在UE（10）处或在基站（12）处执行。 在一个实施例中，多个UE速度范围被定义（例如，低，中等，高），具有与每个范围相关联的对应的移动性参数值。

Abstract: A user equipment for handling a cell change from a first cell to a second cell in a wireless communications network alters a duration of a measurement time over which at least one measurement is performed and alters a measurement bandwidth of the at least one measurement.
