摘要： A base station that implements an improved link adaptation process that takes into account the fact that a certain reference signal (e.g., CSI-RS) may be seen as interference by certain wireless communication devices (WCDs). Accordingly, when the base station schedules a data transmission for the WCD to occur in a particular ΤΉ and the base station is scheduled to transmit the CSI-RS during the same TTI, the base station will tend to select a more robust MCS for the data transmission to the WCD to counter effect the possible interference caused by the CSI-RS.
摘要翻译：实现改进的链路自适应过程的基站，其考虑到某些参考信号（例如，CSI-RS）可被视为某些无线通信设备（WCD）的干扰的事实。因此，当基站调度在特定的T H H发生的WCD的数据传输，并且基站被调度为在相同的TTI期间发送CSI-RS时，基站将倾向于为数据选择更稳健的MCS 传输到WCD以对抗CSI-RS引起的可能干扰。

摘要： A method includes a base station in a distributed antenna system having a set of antennas. For each antenna, the base station stores state information indicating that the antenna is either in a transmit state or a do_not_transmit state. For each antenna indicated by the state information for the antenna as being in the transmit state, the base station determines whether the antenna has been given a clear channel indication (CCI) for a next transmission time interval (TTI). At the next TTI, the base station transmits data to a UE, wherein the base station transmits the data to the UE using antennas included in said set of antennas that i) are indicated by the state information for the antenna as being in the transmit state and ii) have been given the CCI. The base station adjusts the state information in accordance with a transmit status.

摘要： A method performed by a network node 110, for improving the performance of a handover of a user equipment (UE) 120, wherein the network node 110 serves a first cell 130 comprising one or more UEs 120. When the network node 110 has detected that a Signaling Radio Bearer (SRB) is determined to be scheduled for a UE 120 in handover from the first cell 130 to a second cell 131, the network node 110 increases the Control Channel Element (CCE) aggregation level in an OFDM-subframe to be sent to the UE 120 in a TTI related to the handover. By increasing the CCE aggregation level during a handover procedure, the effective coding rate of the PDCCH is increased, which leads to a more robust coding and reliability. Thereby the number of unsuccessful handovers and lost service is effectively reduced.
摘要翻译：由网络节点110执行的用于改善用户设备（UE）120的切换的性能的方法，其中网络节点110服务于包括一个或多个UE 120的第一小区130.当网络节点110已经检测到在从第一小区130切换到第二小区131的过程中，确定信令无线电承载（SRB）被调度给UE 120，网络节点110将OFDM子帧中的控制信道元素（CCE）聚合等级增加到在与切换有关的TTI中发送到UE 120。通过在切换过程中增加CCE聚合等级，增加了PDCCH的有效编码率，从而导致更可靠的编码和可靠性。由此有效地减少了不成功的切换次数和丢失的服务次数。
