摘要： The present invention relates to a solution for extending the cell range and in particular for a solution for handling timing alignment. The solution comprises determining a distance between user equipment and a radio access network node. User equipment located at a distance related to a pre defined timing advance value is scheduled to handle uplink communication so as to arrive at a later time slot for reducing the risk of conflicting with other transmissions towards the access node.

摘要： Methods and apparatus for accessing a wireless communications system, and corresponding methods and apparatus for processing random access attempts, are disclosed. An exemplary method comprises detecting random-access information transmitted by a base station node (130), transmitting a random-access preamble to the base station node (130) according to the random-access information, and receiving a random-access response from the base station node (130). The random-access response includes at least an allocation of uplink resources to be used for the next step in the random access procedure. The method further includes selecting a reference signal sequence index from a pre-determined set of sequence indexes, and transmitting a first message to the base station node (130) using the uplink resource allocation provided in the random-access response, the first message comprising a device identifier and a first demodulation reference signal derived from a base reference sequence shifted according to the selected sequence index.

摘要： The disclosure relates to methods and devices for performing uplink power control in a radio communication system. An example method comprises a step of receiving (111), at a user equipment (UE) a transmit power control (TPC) command. The method also comprises, if the UE does not have an uplink transmission scheduled for a subframe associated with the TPC command, a step of accumulating (113), by the UE, the TPC command with previously received TPC commands based on whether the UE has reached a maximum transmit power or a minimum transmit power in a reference format for a Physcial Uplink Shared Channel (PUSCH), Sounding Reference Signal (SRS) or Physical Uplink Control Channel (PUCCH) transmission. Thus the UE is enabled to receive TPC commands while the UE is not transmitting anything in the uplink.
摘要翻译：本公开涉及用于在无线电通信系统中执行上行链路功率控制的方法和装置。一种示例性方法包括在用户设备（UE）处接收（111）发射功率控制（TPC）命令的步骤。该方法还包括如果UE没有针对与TPC命令相关联的子帧调度的上行链路传输，则由UE根据UE是否具有先前接收到的TPC命令累积（113）TPC命令的步骤达到物理上行链路共享信道（PUSCH），探测参考信号（SRS）或物理上行链路控制信道（PUCCH）传输的参考格式的最大发射功率或最小发射功率。因此，当UE不在上行链路中传输任何内容时，UE能够接收TPC命令。

Some of the example embodiments presented herein are directed towards a base station, and corresponding method therein, for uplink timing alignment. The base station (401) may be configured to estimate a proximity of the user equipment (501) to an uplink receive or an uplink cell size of the user equipment. The base station may determine a TAC MAC CE based on the estimation and send the TAC MAC CE to the user equipment (501 ) for uplink timing alignment.

摘要： A method in a network node for transmitting control information to a user equipment in a telecommunications system is provided. The control information is scheduled in time intervals of a downlink shared data channel, wherein the control information is allocated resource elements in resource blocks of a time-frequency Orthogonal Frequency Division Multiplexing, OFDM, grid in the time intervals in which the control information is scheduled. The network node determines for a time interval, a set of user equipments for which control information is scheduled in the time interval. Also, it selects for a user equipment comprised in the determined set of user equipments, at least one group of user equipments amongst one or more groups of user equipments to which the user equipment is assigned. It also prepares a group signal corresponding to the selected one group of user equipments by allocating resource elements in the resource blocks of the time interval to the group signal. Furthermore, the network node transmits the prepared group signal in the allocated resource element in the time interval to the user equipment such that the user equipment is enabled to determine whether the control information that is allocated resource elements in the time interval is intended for the user equipment or not. A network node, a method in user equipment and a user equipment are also provided.

摘要： A new uplink control channel capability is introduced to enable a mobile terminal to simultaneously report to the radio network multiple packet receipt status bits and channel-condition bits. In particular, if a mobile terminal is configured with channel selection (e.g., with PUCCH format 1b) and is configured to report or is capable of reporting periodic CSI and ACK/NACK bits together, then the mobile terminal can use one or more out of a set of preconfigured uplink control resources and transmit (1140) a PUCCH using a new format in this resource. The particular uplink control channel resource the mobile terminal uses from this set is selected (1120) based on an information field contained in a downlink control message corresponding to the ACKed or NACKed data transmission, for example, such as the Transmit Power Control (TPC) command in a downlink assignment message.
摘要翻译：引入了新的上行链路控制信道能力，使得移动终端能够同时向无线电网络报告多个分组接收状态比特和信道条件比特。特别地，如果移动终端配置有信道选择（例如，使用PUCCH格式1b）并且被配置为报告或能够将周期性CSI和ACK / NACK比特报告在一起，则移动终端可以使用一个或多个一组预配置的上行链路控制资源，并在该资源中使用新格式发送（1140）PUCCH。基于包含在与ACK / NACK数据传输相对应的下行链路控制消息中的信息字段，例如发射功率控制（TPC）等，选择移动终端从该组使用的特定上行链路控制信道资源（1120）命令在下行链路分配消息中。

摘要： Devices and methods for transmitting information in resource blocks between a base station and one or more communication devices are disclosed. In each resource block (RB) used for a data or control channel transmission, a plurality of non-over!apping regions of resource elements (REs) are defined. Each region is associated with one or multiple unique reference symbols (RSs), and may be further associated with one or more antenna ports. When user equipment (UE) demodulates the information it receives in a particuiar region of an RB, it uses the RS and/or antenna port associated with that region. The RS and/or antenna port information may be used, for example, to estimate a channel of the communication network or to demodulate and decode the data contained within the associated regions.

摘要： The present invention relates to a base station (BS) and to a method for supporting UE positioning measurements in a wireless communication system. The method comprises transmitting (610) signals associated with a first cell, where the signals comprise positioning reference signals. The method also comprises transmitting (620) signals associated with a second cell, wherein the second cell is configured to have a lower transmission capacity than the first cell, and discontinuing (630) the transmission of at least one signal associated with the first cell except for the positioning reference signals. The energy consumption of the BS may thus be reduced while still supporting accurate positioning measurements.
