摘要： Automatically adjust the size of a Physical Uplink Control Channel, PUCCH, of an uplink communication subf rame. In a particular embodiment, the size of a semi-static region of the PUCCH is adjusted. The adjustment is based on a utilization factor of the PUCCH over a time period. The adjustment can also be based on the connection factor (connections between the wireless terminals and the cell) and/or based on the utilization factor of a PUSCH (Physical Uplink Shared Channel). The result is an efficient resource utilization on the PUCCH, and a properly dimensioned PUCCH region.

摘要： The downlink control channels in a control region of each downlink subframe in a telecommunication system are divided into at least one common subset of the downlink control channels and a plurality of group subsets of the downlink control channels, such that the common subset or each common subset will be decoded by every user equipment, and each group subset will be decoded only by a limited group of user equipments. Resource assignment messages for a user equipment can then be transmitted on a downlink control channel of the relevant group subset, to avoid the need for messages to be decoded by a large number of UEs that will not act on them, while broadcast messages can be transmitted on a downlink control channel of the relevant common subset, to avoid the need for messages to be transmitted many times.
摘要翻译：电信系统中每个下行链路子帧的控制区域中的下行链路控制信道被划分为下行链路控制信道的至少一个公共子集和下行链路控制信道的多个组子集，使得公共子集或每个公共子集将由每个用户设备解码，并且每个组子集将仅由有限的一组用户设备解码。然后可以在相关组子集的下行链路控制信道上发送用于用户设备的资源分配消息，以避免对不能对其进行动作的大量UE进行解码的消息的需要，同时可以发送广播消息在相关公共子集的下行链路控制信道上，以避免需要多次发送消息。

摘要： A method in a base station (105) for handling a scheduling of a narrowband transmission from a user equipment (135) in a cell (110) served by the base station (105) is provided. The base station (105) and the user equipment (135) are comprised in a cellular network (100). A time resource available for the scheduling is divided into available subframes. A frequency resource available for scheduling in each respective subframe is divided into available resource blocks. The base station (105) selects a subframe among the subframes available for scheduling. Narrowband transmissions are to be prioritized for scheduling to the selected subframe. The base station (105) schedules the transmission to a subset of the available resource blocks in the selected subframe when an indication that the transmission from the user equipment (135) is a narrowband transmission is obtained.

摘要： A basic idea is to introduce an additional paging schedule for user equipment in connected mode that differs from the paging schedule used for user equipment in idle mode. Consequently, the inventive mechanism relies on distributing (S1) a notification of an upcoming change of system information in paging messages according to a first paging schedule for user equipment in idle mode, and distributing (S2) a notification of an upcoming change of system information in paging messages according to a second paging schedule for user equipment in connected mode. The second paging schedule for user equipment in connected mode is different from the first paging schedule for user equipment in idle mode. In this way, a satisfactory load distribution is achieved, at the same time as UEs in both connected and idle mode are able to receive important system information notifications.
摘要翻译：一个基本思想是为连接模式下的用户设备引入附加的寻呼时间表，而不同于用于空闲模式的用户设备的寻呼时间表。因此，本发明的机构依赖于根据用于空闲模式的用户设备的第一寻呼调度，在寻呼消息中分发（S1）系统信息即将到来的更改的通知，并且分发（S2）即将到来的系统信息改变的通知在寻呼消息中根据用于连接模式的用户设备的第二寻呼时间表。连接方式的用户设备的第二个寻呼调度与空闲模式下的用户设备的第一个寻呼调度不同。以这种方式，实现令人满意的负载分配，同时连接和空闲模式中的UE能够接收重要的系统信息通知。

摘要： A method performed by a network node 110, for handling 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 number of OFDM-symbols included in a control region of a downlink OFDM-subframe sent in the first cell 130 in a Transmission Time Interval (TTI) related to the handover. By increasing the number of OFDM-symbols of the control region only during the handover, the physical downlink control channel (PDCCH) is spread in time into symbols not polluted by CRS symbols from neighboring cells. Thereby the number of unsuccessful handovers and lost service is effectively reduced.

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.
