摘要： The teachings herein provide a number of advantages, including but not limited to improving soft-cell operation in service scenarios involving legacy devices that do not directly support carrier aggregation—i.e., devices that can transmit or receive in only one frequency band at a time. By imposing a Time Division Duplex (TDD) arrangement across two carriers operating in different frequency bands, scheduled transmissions involving the legacy device are mutually exclusive as between the two carriers. Advantageously, the TDD arrangement is imposed across first and second carriers used in the macro- and low-power layers of a soft-cell, thus imposing TDD-based coordination of scheduled transmissions between those carriers irrespective of whether the individual carriers are configured as Frequency Division Duplex (FDD) or TDD carriers, or a mix thereof.

摘要： The present invention relates to exchanging a cell-specific parameter such as the A-MPR, comprising information related to a required additional maximum power reduction of a UE transmitter between networks nodes. The networks nodes may be radio base stations or other network nodes such as radio network controllers or core network nodes exemplified by access gateways (aGWs). By exchanging this cell-specific parameter with information of the required additional maximum power reduction between the network nodes, the cell-specific parameter is provided to the radio base station of the serving cell which implies that the serving cell can send the cell-specific parameter of the target cell to the UE prior to the handover from the serving cell to the target cell. This result in that the UE can start transmission to the target cell with the correct cell-specific parameter and the out-of-band emission requirements can be fulfilled in the target cell.
摘要翻译：本发明涉及交换诸如A-MPR的小区特定参数，包括与网络节点之间的UE发射机所需的附加最大功率降低有关的信息。网络节点可以是无线电基站或诸如无线电网络控制器或由接入网关（aGW）示例的核心网络节点的其他网络节点。通过将该小区特定参数与网络节点之间所需的附加最大功率减少的信息交换，将小区特定参数提供给服务小区的无线电基站，这意味着服务小区可以发送小区特定参数在从服务小区切换到目标小区之前，将目标小区发送给UE。这导致UE可以以正确的小区特定参数开始传输到目标小区，并且可以在目标小区中满足带外发射要求。

摘要： A method in a first radio communication node (110, 310, 710, 1010) and a first radio communication node (110, 310, 710, 1010) for scheduling a data transmission in a first time frame using one of a plurality of modulation and coding schemes are provided. The data transmission is to be transmitted between the first radio communication node (110, 310, 710, 1010) and a second radio communication node (120, 320, 720, 1020). The first radio communication node (110, 310, 710, 1010) obtains (301, 701, 1001, 1401) a first indication about channel quality for the first time frame. The first radio communication node (110, 310, 710, 1010) obtains (302, 702, 1002, 1402) second indication about a possible upcoming transmission failure. The possible upcoming transmission failure relates to a feedback information to be transmitted in a second time frame. The feedback information is associated with the data transmission in the first time frame. The first radio communication node (110, 310, 710, 1010) selects (303, 703, 1003, 1403) a modulation and coding scheme out of said plurality of modulation and coding schemes based on the first indication and the second indication. Next, the first radio communication node (110, 310, 710, 1010) schedules (304, 704, 1004, 1404) the data transmission using the selected modulation and coding scheme.

摘要： The present invention relates to scheduling of uplink and downlink resources between mobile terminals (110, 120) and a base station (130). To reduce the power leakage between the transmitter and the receiver of the mobile terminal (110), the scheduler allocates uplink frequency carriers and downlink frequency carriers with a large duplex distance to those mobile terminals (110, 120) that have to transmit with high power. This means that the requirements on the external SAW filter could be reduced.

摘要： A mobile terminal transmits one or more first communication channels in a first frequency region and one or more second communication channels in a second frequency region. With the channels experiencing different fading conditions, the terminal receives separate transmit power control (TPC) commands. Instead of simply adjusting the transmit power of the channels as commanded, the terminal computes a power offset indicative of the difference between the commanded power of one or more of the first channels and the commanded power of one or more of the second channels. The terminal then selectively performs transmit power control of the first and second channels on either an independent basis, according to the respective TPC commands, or a joint basis, depending on whether the computed power offset falls outside of a pre-determined range of values. In doing so, the terminal allows independent control of channels, while also mitigating self-interference and/or spectral emissions.
摘要翻译：移动终端在第二频率区域中的第一频率区域和一个或多个第二通信信道中发送一个或多个第一通信信道。通道经历不同的衰落条件时，终端接收单独的发射功率控制（TPC）命令。代替简单地按照命令调整信道的发射功率，终端计算表示一个或多个第一信道的命令功率与一个或多个第二信道的命令功率之间的差的功率偏移。然后，根据所计算的功率偏移是否超出预定值的范围，终端根据相应的TPC命令或联合基础，独立地选择性地执行第一和第二信道的发射功率控制。在这样做时，终端允许信道的独立控制，同时也减轻自身干扰和/或频谱发射。

摘要： Mobile communication system equipment avoids interfering with another transmitter's operation. Sensing information indicating whether the other transmitter's signal has been detected is received from remote sensors, wherein each of the remote sensors is situated at a respective one of two or more sensor locations. The sensing information and information about the sensor locations is used to ascertain one or more exclusion boundaries needed to avoid interfering with the other transmitter's use of the spectral resource. Beamforming parameters are ascertained that will enable the main node to transmit within one or more predefined geographical areas except for any portion of a predefined area located on a far side of the one or more exclusion boundaries. Two or more adjusted signals are produced as a function of the beamforming parameters and one or more signals to be transmitted. The adjusted signals are transmitted from respective ones of two or more antennas.
