Abstract: The present invention relates to methods and arrangements that enable a User Equipment UE to limit the number of sub cell searches needed in a wireless communication system with Coordinated Multiple Point transmission/reception (CoMP) cells, while keeping an acceptable system performance at handovers. This is achieved by a solution where the UE does sub cell search in a candidate target CoMP cell only when the candidate target CoMP cell quality performance is within a reasonable range or when the serving CoMP cell quality performance is low.

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. The alterations may be performed based on associated bandwidths of the first and second cells. A network node sends, to the user equipment, a notification of a cell change and information associated with the cell change and also receives measurement data of at least one measurement performed over an altered measurement bandwidth and an altered duration of measurement time where the alterations are based on the information associated with the cell change.

Abstract: The present invention relates to a user equipment and a network node, and to related methods of supporting resource efficient ad hoc networking between user equipments (UEs) of a cellular network. This is addressed by a solution where the network node is supporting the ad hoc networking between UEs. The network node is capable of 5 accessing a user equipment capability database and receives (210, 220) update messages from UEs (UE1, UE2) comprising information regarding the capabilities of the user equipments such as supported frequency bands, RATs and antenna modes. The network node updates (230) the user equipment capability database (DB) with the information comprised in the received update message, and determines based on the 10 information stored in the user equipment capability database and a matching algorithm (240), that UE1 and UE2 have matching capabilities and are able to communicate wirelessly. The network node then transmits (250) an ad hoc “paging” message comprising the UE1 and UE2 identities. The “paging” message is received by the UE1 and UE2 identified in the “paging” message, and UE1 may then e.g. establish an ad hoc 15 network with UE2 (260).

Abstract: A first radio network node (HBS1) adapts its physical cell identifier (PCI1) based on a comparison of its PCI1 to a second PCI (PCI2) used by a neighboring interfering second radio network node (e.g., another HBS2 or a macro node). The first radio network node HBS1 determines the second PCI based on one or more radio measurements performed on a cell 402 and/or on a UE 404 served by the second node. The adaptation of the cell identifier PCI1 is used for one or more radio network management tasks, e.g., resource management such as interference mitigation in a heterogeneous network, radio network planning, etc.
