摘要： A cell search and synchronization method in a 5G wireless communication system in which a cell, with which a terminal wishes to synchronize, has a frequency span in the frequency domain. The method comprising setting (S100) a numerology for the system in dependence on the frequency span, which determines a channel raster used in the cell; defining (S102), using the channel raster, a plurality of possible resources distributed over the frequency span for transmitting PSS/SSS/PBCH; determining (S104) how many instances of PSS, SSS and PBCH are required in the current time period; transmitting (S106) the number of instances of PSS, SSS and PBCH thus determined; and a terminal detecting one or more instance of PSS/SSS/PBCH in order to connect with the cell. Multiple transmissions of PSS/SSS/PBCH allow a terminal to detect these signals more easily, and facilitate use of PSS or SSS as reference signs for RRM purposes. Different numbers of PSS/SSS/PBCH may be transmitted with respective mappings between them, and the numbers of transmissions may vary over time.

摘要： A method for operating and controlling devices (12) connected to a network which allows the transmission of small data packets after reading System Information. The network can control a cell to allow access from devices (12) using an extended coverage mode, ECM, outside the normal coverage area of the cell. Initial access from devices in the extended cell coverage area can be scheduled (S104, S110) with the use of a pre-defined scheduled time for the devices to access the cell. A transmission of a schedule for ECM operation to the devices (12) that are using the ECM is provided (S144) after an ECM capable device has been moved from idle to connected mode for the first time, and can be updated (S146) at every scheduled opportunity when the device subsequently moves to connected mode. In addition, embodiments of the present invention provide a modified RACH procedure (S122, S128, S134, S140) to be followed by devices (12) taking advantage of the ECM.

摘要： In an LTE-based wireless communication system, a mechanism is provided for allowing a UE (10) in a dual connectivity mode to carry out a procedure for secondary cell handover. The UE does not follow a random access procedure to obtain the timing information of the new secondary cell, but instead obtains it from its connection with the master cell, thereby saving time. The master cell instructs the UE 10 (S16) to initiate wireless connection with the new secondary cell, and indicates (S18), by RRC, MAC or PHY signalling to the UE how to derive the UL timing in the new secondary cell, or the UL/DL timing difference for the new secondary cell. Based on this indication the UE 10 synchronizes with the new cell (S20). The mechanism applies to both the cases where an additional connection is established or a UE is switched to a different secondary cell.
摘要翻译：在基于LTE的无线通信系统中，提供了一种允许双连接模式的UE（10）执行二次小区切换的过程的机制。 UE不遵循随机接入过程来获得新的辅助小区的定时信息，而是从其与主小区的连接获得它，从而节省时间。主单元指示UE 10（S16）发起与新的二级小区的无线连接，并通过RRC，MAC或PHY信令向UE指示（S18）如何在新的二级小区中导出UL定时，或者新二次电池的UL / DL时序差异。基于该指示，UE 10与新小区同步（S20）。该机制适用于建立附加连接或将UE切换到不同二次小区的情况。

摘要： In a wireless communication system, two cells (cell 1, cell 2) co-exist in the same time/frequency resources with the same Cell ID. The two cells are differentiated by one being a legacy cell and the other being a cell in which coverage extension by means of signal repetition is applied. There is a corresponding difference in broadcast control channels transmitted by a base station (11) providing the two cells, for example a difference in one or more of the contents of the PBCH, or the repetition factor on the PBCH, and/or a difference in a higher-level ID. The second cell is intended for machine type communication where coverage enhancement is required.

摘要： An access method of a device (10) such as an MTC device to a network (20, 30, 40) which allows the transmission of small data packets without the need to read all the System Information normally required to make an initial network access. The device (10) may notify the network that an access request is occurring from a device that was either specifically allowed to use a stored access configuration or is accessing the cell using modified system information being broadcast by the cell. Such notification may be implicit in the characteristics (choice of preamble, timing, frequency and/or repetition) of the access request. The network, preferably having knowledge of the method being used by the device to access the network, can either reject this access or accept it depending on whether the access was from a stored configuration or read from System Information.

摘要： A method for configuring a search space within which a mobile terminal performs blind decoding attempts for potential control message candidates which may be transmitted by a base station. The frequency domain resource for which the terminal performs a blind decoding attempt for a given candidate message is determined by a pseudo-random selection (known by both terminal and network) from a pre-determined set of possible resources. A difference from prior art is that pre-determined set of resources can be different for each candidate. In a preferred embodiment the set of resources is configured by the network for each terminal and each candidate. The method may be applied for example to ePDCCH of an LTE-A wireless communication system.

摘要： In wireless communication systems such as LTE, a mobile terminal (10) may transmit data in the uplink using PUSCH. The resources for such transmissions are typically granted by the network using a control channel message sent using PDCCH. When the mobile terminal wishes to transmit buffer status information to a base station (20), but no suitable resources for transmission of a buffer status report (BSR) have been granted by the network, this leads to the triggering of a scheduling request (SR) at the mobile terminal (10). The invention provides for transmission of buffer status (or possibly other information) along with the SR for the case of terminals with more than one antenna port simultaneously available in the uplink (UL). The invention is based on the recognition that LTE Release 10 provides for SR to be transmitted simultaneously on different UL antenna ports with different resources. The additional information on buffer status may be encoded by transmission of different SR signals (e.g. QPSK symbols) on the different antenna ports.
摘要翻译：在诸如LTE的无线通信系统中，移动终端（10）可以使用PUSCH在上行链路中发送数据。这种传输的资源通常由网络使用使用PDCCH发送的控制信道消息来授予。当移动终端希望向基站（20）发送缓冲器状态信息时，但没有用于传输缓冲状态报告（BSR）的合适资源已被网络授予，这导致触发调度请求（SR ）移动终端（10）。本发明提供了对于在上行链路（UL）中同时可用的具有多于一个天线端口的终端的情况，缓冲器状态（或可能的其他信息）以及SR的传输。本发明基于LTE版本10提供在不同的具有不同资源的不同UL天线端口上同时传输的SR的认识。关于缓冲器状态的附加信息可以通过在不同天线端口上传送不同的SR信号（例如QPSK符号）进行编码。
