摘要： Error vector magnitude (EVM) is pooled and adaptively distributed among carriers in a multi-standard or multi-carrier system to reduce peak to average power ratios (PAPR) without exceeding EVM limits. Correction tone injection is used to reduce PAPR. The amplitude of each correction tone, and number of correction tones assigned to a carrier, are adjusted to control the EVM and out-of-band distortion of each carrier, to comply with EVM limits imposed by the respective radio access technology.

摘要： Some of the example embodiments presented herein are directed towards a user equipment (501), and corresponding method therein, for uplink timing alignment. The user equipment (501) may initiate a timing advance value to zero during a creation of a timing advance group, a modification of a timing advance group, or if a TAC MAC CE command has not been performed. The user equipment (501) may further update the timing advance value based on a received TAC MAC CE command. 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.
摘要翻译：本文提出的一些示例性实施例针对用于上行链路定时对准的用户设备（501）及其中的相应方法。用户设备（501）可以在创建定时提前组，定时提前组的修改或者还没有执行TAC MAC CE命令时启动定时提前值为零。用户设备（501）还可以基于所接收的TAC MAC CE命令更新定时提前值。这里呈现的一些示例实施例针对基站，以及其中的相应方法，用于上行链路定时对准。基站（401）可以被配置为估计用户设备（501）与用户设备的上行链路接收或上行链路小区大小的接近度。基站可以基于估计来确定TAC MAC CE，并将TAC MAC CE发送给用户设备（501）以进行上行链路定时对准。

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.
摘要翻译：本发明涉及一种基站（BS）以及一种在无线通信系统中支持UE定位测量的方法。该方法包括发送（610）与第一小区相关联的信号，其中信号包括定位参考信号。所述方法还包括发送（620）与第二小区相关联的信号，其中所述第二小区被配置为具有比所述第一小区更低的传输容量，以及中断（630）与所述第一小区相关联的至少一个信号的传输，用于定位参考信号。因此，可以减少BS的能量消耗，同时仍然支持准确的定位测量。

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： The present invention relates to methods and arrangements in a RBS and a UE for reference signal (RS) measurements in an OFDM system, that enable having a configurable RS transmission bandwidth which is smaller than the system bandwidth. This allows for better interference coordination of RS, which in turn improves the UE RS measurements used for different services such as positioning. The RBS retrieves (710) the RS transmission bandwidth, determines (720) a RS measurement bandwidth based on this RS transmission bandwidth, and transmits (730) the determined bandwidth to the UE. The UE receives (810) the RS measurement bandwidth and measures (820) the RS in a bandwidth determined based on the received measurement bandwidth and the UE capability.

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。
