    • Systems and methods for dynamic cell breathing for power saving are disclosed. In some embodiments, a method of operation of a radio access node includes determining a target transmit power level from multiple predetermined transmit power levels for the radio access node. The method also includes determining that the current transmit power level should be adjusted to reach the target transmit power level and, in response, adjusting a transmit power level of the radio access node from the current transmit power level to the target transmit power level via multiple transmit power level adjustments. Adjusting the power level of the radio access node via more than one transmit power level adjustment makes it possible to avoid some of the issues with the sleep mode proposal, according to some embodiments.

    • A method and apparatus is provided for allocating shared control channel resources. The control channel elements (CCEs) are allocated in units referred to as CCE sets. Each CCE set includes one or more control channel elements. Early commitment of control channel elements in a CCE set to a specific scheduling entity is avoided in situations where two or more candidate sets are available for the scheduling entity. In this case, the CCEs belonging to the candidate sets are designated as an alternate resource for a first scheduling entity. A CCE designated as an alternate may be allocated to another scheduling entity as long as such allocation does not block the first scheduling entity.
    • 提供了一种用于分配共享控制信道资源的方法和装置。 控制信道单元(CCE)以被称为CCE组的单元分配。 每个CCE集合包括一个或多个控制信道元素。 在两个或多个候选集合可用于调度实体的情况下,避免在设置到特定调度实体的CCE中的控制信道单元的早期承诺。 在这种情况下,属于候选集的CCE被指定为第一调度实体的备用资源。 只要这种分配不阻止第一调度实体,指定为替换的CCE可以被分配给另一个调度实体。

    • A method of paging a mobile terminal in a radio access network wherein the last known location of a mobile terminal is stored. A location message (also called a Route Update message) is sent from a terminal and received at a sector in the network, identifying the location of the terminal. The network determines a paging zone for that terminal based on configuration information for that sector. The configuration information for each sector typically includes a Route Update radius, and then one or both of a paging zone radius offset, and statically configured sectors. When the terminal needs to be paged, the network then broadcasts a page to the terminal in each sector in the paging zone. Such a system adjusts the paging zone to include sectors which the terminal has a reasonable likelihood of moving to before the network learns that the terminal has moved out of the previously established paging zone. Aspects of the invention provide two complementary methods of adjusting the paging zone: adjusting using a paging zone offset, and adjusting based on a sector list. The paging zone offset adjusts the radius of the paging zone, thereby maintaining a generally circular shape. The sector list adjusts the generally circular paging zone by adding or deleting any sector in any direction, thereby allowing any arbitrary shape to be used for the paging zone. The adjustments to the paging zone achieved by these methods account for such factors as RF coverage, geographic features, congestion, population density and expected rate of movement of terminals between sectors.
    • 一种在无线电接入网络中寻呼移动终端的方法,其中存储了移动终端的最后已知位置。 从终端发送位置消息(也称为路由更新消息),并在网络中的扇区处接收,以识别终端的位置。 该网络基于该扇区的配置信息确定该终端的寻呼区域。 每个扇区的配置信息通常包括路由更新半径,然后包括寻呼区半径偏移和静态配置扇区中的一个或两个。 当终端需要被寻呼时,网络然后在寻呼区域的每个扇区中向终端广播一个页面。 这样的系统调整寻呼区域以包括终端在网络学习终端已经移出先前建立的寻呼区域之前具有合适的可能性的扇区。 本发明的各方面提供了两种调整寻呼区域的补充方法:使用寻呼区域偏移进行调整,以及基于扇区列表进行调整。 寻呼区域偏移调整寻呼区域的半径,从而保持大致圆形的形状。 扇区列表通过在任何方向上添加或删除任何扇区来调整通常循环的寻呼区域,从而允许任何形状用于寻呼区域。 通过这些方法实现的寻呼区域的调整涉及射频覆盖,地理特征,拥塞,人口密度和部门之间终端的预期移动速度等因素。
