摘要： A base station transmits signals on a frequency (f 1 ) in an active transmission interval (TI) having a starting time and being part of a transmission cycle (TC) including other active transmission intervals for other frequencies (f 0 , f 1 , f 2 , f 3 ) appearing in a predetermined discontinuous transmission scheme that specifies the relationship (Δ 1 , A 2 , A 3 ) between the starting times of the active transmission intervals of the frequencies of the set. The mobile station scans the set of frequencies during a scanning cycle (SC) corresponding to the transmission cycle (TC) and determines the frequencies at which the base stations transmit. The start of each scanning is made at a point in time that is specified for the corresponding frequency by the discontinuous transmission scheme and the scanning of one frequency involves ending scanning of this frequency at the end of a time range (TR) of pre-determined length if no signal is detected within this time range.

摘要： The present invention relates to methods and arrangements in a multi-carrier system. It also assumes independent DRX (Discontinuous reception) functionality on respective component carriers and the possibility for one carrier, e.g. the anchor carrier to initiate a change of DRX state for another component carrier. The basic concept of the present invention is to introduce a new "dormant" state in the DRX logic, whereby the dormant state can be used for non-anchor carrier components. The dormant DRX state implies that a carrier of a UE having this state is not required to monitor system signaling. In embodiments of the present invention this new state is introduced for a particular component carrier (e.g. non-anchor component carrier) for a UE operating in a multi-carrier system, and how to perform the transitions to and from the dormant DRX state implicitly, e.g. based on configured timer(s) for the component carrier or explicit signaling in a different (e.g. anchor) component carriers.

摘要： The present invention provides a method, a radio base station (40) and a mobile terminal (50) for allocating resources in a telecommunications network, where communications between the radio base station (40) and the mobile terminal (50) take place over a plurality of carriers. The method comprises transmitting and receiving a resource allocation message comprising one or more bits. Each of the bits corresponds to a number of resource blocks, where the number is determined from the ratio of the aggregate bandwidth of the plurality of carriers divided by the bandwidth of the carrier over which the resource allocation message is sent.

摘要： Mechanism to receive control signals transmitted from a base station (210, 510, 910) to the user equipment (220, 520, 920) in a manner that minimizes power consumption on the user equipment (220, 520, 920) while still maintaining some acceptable level of performance is described. The user equipment (220, 520, 920) periodically measures the signal quality of component carriers used by the base station (210, 510, 910) and requests control signaling (anchor) carrier reselection. Either a single component carrier can be chosen if the single carrier has sufficient quality or multiple component carriers can be selected when the quality of the single quality is low. The anchor carrier reselection may also be triggered to manage the system as a whole. For fast moving user equipments (220, 520, 920), anchor carrier hopping pattern can be provided to increase robustness and reduce reselection signaling overhead.

摘要： An extended cell search procedure enables more inclusive measurement reports by mobile terminals operating in a heterogeneous network. The mobile terminal may be configured to conduct an extended cell search to enable better detection of signals transmitted from weaker cells. For mobile terminal with extended cell search capabilities, the network sends an extended cell search message to the mobile terminal when there is a need for an extended cell search. In response to the extended cell search message, the mobile terminal uses an extended cell search procedure rather than the normal cell search procedure (as specified in Rel-8 of the LTE standard) when performing cell searches.

摘要： In a heterogeneous network cell deployment a mobile terminal may need to receive control data transmissions from a macro node at the same time as a pico node is transmitting user data for the mobile terminal, using the same frequency or set of frequencies. This can result in a problematic interference situation. According to several embodiments of the present invention, at least one of two general approaches is used to mitigate the interference situation described above. In a first approach, the pico node's transmission power is reduced in some time intervals, thereby reducing the interference to a level where reception from the macro node is possible. In a second approach, which may be combined with the first approach in some cases, relevant data (e.g. control information) transmitted from the macro node is provided by the pico node, either alone or in combination with the macro node (i.e. simultaneously to the macro node during the same protected transmission time intervals).
摘要翻译：在异构网络小区部署中，移动终端可能需要在微微节点正在使用相同的频率或频率集合为移动终端发送用户数据的同时从宏节点接收控制数据传输。这可能导致有问题的干扰情况。根据本发明的几个实施例，使用两种一般方法中的至少一种来减轻上述干扰情况。在第一种方法中，微微节点的传输功率在一些时间间隔内减小，从而将干扰降低到可能从宏节点接收的水平。在一些可能与第一种方法组合的第二种方法中，从宏节点发送的相关数据（例如，控制信息）由微微节点提供，单独或与宏节点组合（即同时到达宏节点在相同的受保护传输时间间隔期间）。
