摘要： A base station device includes: a control signal generator that generates a signal of control data including items corresponding to the type of sub-frames to be allocated; a scheduling information signal generator that generates a signal of scheduling information indicating a sub-frame to be a first sub-frame among sub-frames specified by first-type sub-frame candidate information; and a multiplexer that allocates the signal of the control data to the first-type and second-type sub-frames, and allocates the signal of the scheduling information to the first-type sub-frame. A mobile station device includes: a frame-type determining unit that determines the type of each of received sub-frames based on the first-type sub-frame candidate information and the scheduling information; and a control data detector that detects, for each sub-frame, the control data including the items corresponding to the type indicated by the result of the determination by the frame-type determining unit. Accordingly, the processing load on reception of control data is reduced.

摘要： Systems, methods, and apparatuses for using band-limited subframes in wireless communication networks are provided. During the band-limited subframes, the macro cell base station may mute its transmission or transmit at a low power over some frequency sub-band, while transmitting at a normal or higher power over other frequency sub-band. Correspondingly, the small cell base station may communicate with UEs within its coverage at the frequency sub-band that the macro cell base station transmits at a low power. The band-limited subframe enables the small cell base station to communicate with the UE with reduced interference, and in the meantime, increases the throughput of macro cell base station as it does not require the macro cell base station to completely mute its transmission during the band-limited subframe.

摘要： The present disclosure concerns radio communication. In one of its aspects, the technology presented herein concerns a method performed by a base station 210 for selecting a transmission rank. The method may advantageously be carried out when the base station 210 is operating in a shared cell 200. The base station receives a channel-state report from a user equipment. Also, a channel quality parameter is estimated by the base station 210. Furthermore, the base station 210 selects the transmission rank (e.g. transmission rank 1 or transmission rank 2) on the basis of the received channel-state report as well as the estimated channel quality parameter.

摘要： A method for transmitting a multiple input multiple output (MIMO) packet in a wireless local area network is described. The method includes generating a physical layer protocol data unit (PPDU) including a short training field (STF), a long training field (LTF), a very high throughput (VHT)-signal field, a VHT-STF, a VHT-LTF and a plurality of data streams. The STF is used for at least one receiver to estimate an automatic gain control and a coarse frequency offset. The LTF is used for the at least one receiver to estimate a fine frequency offset. The VHT-STF is used for improving automatic gain control estimation in a MIMO transmission. The VHT-LTF is used for estimating a MIMO channel based on the plurality of data streams. The PPDU is transmitted to the at least one receiver.

摘要： When enabled with common reference signal interference cancellation, a user equipment (UE) may still compute a channel state feedback value with consideration of any canceled interfering neighboring signals. When the neighboring cells are determined to be transmitting data during the time for which the channel state feedback value is being computed, the UE is able to derive the channel state feedback value considering those canceled interfering signals. The UE determines whether each neighboring cell is transmitting during the designated time either by obtaining signals that indicate the transmission schedule of the neighboring cells or by detecting the transmission schedule, such as based on the power class of the neighboring cells. If the UE determines that the neighboring cells are transmitting data during this time period, the UE will compute the channel state feedback value including consideration of the canceled interfering signals.
摘要翻译：当使用公共参考信号干扰消除时，用户设备（UE）仍可以考虑任何取消的干扰相邻信号来计算信道状态反馈值。当在正在计算信道状态反馈值的时间内确定相邻小区正在发送数据时，UE能够导出考虑到那些被消除的干扰信号的信道状态反馈值。 UE通过获得指示相邻小区的传输调度的信号或者通过基于相邻小区的功率等级来检测传输调度来确定在指定时间期间每个相邻小区是否正在发射。如果UE在该时间段期间确定相邻小区正在发送数据，则UE将计算包括考虑被消除的干扰信号的信道状态反馈值。
