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.
摘要翻译：本文的教导提供了许多优点，包括但不限于在不直接支持载波聚合的传统设备（即，一次只能在一个频带中发送或接收的设备）的业务场景中改进软小区操作。通过对在不同频带中工作的两个载波进行时分双工（TDD）布置，涉及传统设备的调度传输在两个载波之间是相互排斥的。有利地，TDD布置被施加在在软小区的宏功率层和低功率层中使用的第一和第二载波上，从而在这些载波之间强加基于TDD的协调调度的传输，而不管各个载波是否被配置为频率分割双工（FDD）或TDD载波，或其混合。

摘要： A UE (10) indicates its radio access capabilities (20) to the base station (30). An element is added to the radio access capabilities (20) reported by the UE (10), to indicate in a release-independent manner if a certain network signaling parameter (e.g., NS-value) has been modified or if a new parameter has been introduced for an operating band. In this manner, the base station (30) can distinguish UE (10) with a modified NS-value behavior from legacy UE (10) for the purpose of admission control, imposing scheduling or handover restrictions, or the like.

摘要： The present invention relates to a method and apparatus for testing mobile terminals in an OFDMA system, in which all or part of available downlink radio resources in a cell are transmitted. A processing unit in a test apparatus splits a set of contiguous resource blocks into separate contiguous portions. A first contiguous portion of the set of resource blocks is allocated to users of a first type, and a second contiguous portion of the set of resource blocks is allocated to users of a second type. A transmitter in the test apparatus transmits test signals to the users of the first type and the second type using the at least one contiguous set of resource blocks.

摘要： According to one aspect, the present invention advantageously provides a method and apparatus that increase communications throughput by manipulating the order or manner in which CQI values are reported in a multi-rank CQI report that constrains one or more such values according to reporting order. As a non-limiting example, the present invention provides that the reporting order used for reporting multiple CQI values is chosen to eliminate or at least reduce under-reporting and over-reporting errors arising from the use of differential reporting formats for one or more of the reported CQI values. Additionally, the present invention provides for selection between single-rank or multi-rank CQI reporting, based on determining which one corresponds to the highest channel capacity, in view of the differential reporting constraints.

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。
