摘要： A mobile communication system includes a plurality of RAT (Radio Access Technology) and can eliminate the need of a control channel for reporting RAT information. An LTE relay station has a cover area identical to a cover area owned by a WLAN host station and relays/transmits the signal received from an LTE base station to a mobile station in the cover area of the LTE relay station. The LTE relay station adds to the signal received from the LTE base station, one of the offsets: a frequency offset, a time offset, and a power offset as information indicating that the mobile station which receives a relay signal from the local station is located in the cover area of WLAN and transmits the signal after offset addition to the mobile station located in the cover area of the LTE relay station (i.e., the cover area of WLAN).

摘要： A radio communication device in which the waste of physical resources involved in the repetition transmission of a response signal can be minimized with no restriction on the scheduling of a base station imposed or with the restriction on the scheduling thereof minimized. In this device, a control unit (209) selects the ZAC sequence of the cyclic shift amount corresponding to a PUCCH number inputted from a determination section (208) from among ZAC#0 to ZAC#11 to set it to a spreading section (215) and selects the block-wise spreading code sequence corresponding to the PUCCH number inputted from the determination section (208) from BW#0 to BW#2 to set it to a spreading section (218). More specifically, the control unit (209) selects any of the resources defined by the ZAC#0 to ZAC#11 and the BW#0 to BW#2. As a result, the more the number of transmissions of the response signal, the less the number of resources the control unit (209) can select.

摘要： Provided is a wireless communication apparatus wherein channel estimation accuracy is improved while keeping the position of each bit in a frame, even when a modulation system having a large modulation multiple value is used for a data symbol. In the wireless communication apparatus (100), an encoding section (101) encodes and outputs transmitting data (bit string) to a bit converting section (102), and the bit converting section (102) converts at least one bit of a plurality of bits constituting a data symbol to be used for channel estimation, among the encoded bit strings, into ‘1’ or ‘0’ and outputs it to a modulating section (103). The modulating section (103) modulates the bit string inputted from the bit converting section (102) by using a single modulation mapper and a plurality of data symbols are generated.

摘要： The invention relates to a method for providing control signalling associated to a protocol data unit conveying user data in a mobile communication system and to the control channel signal itself. Furthermore, the invention also provides a mobile station and a base station and their respective operation in view of the newly defined control channel signals defined herein. In order to reduce the control channel overhead, the invention suggests defining a common field for the transport format and redundancy version in the control channel information format. According to one approach, the common field is used to jointly encode transport format and redundancy version therein. According to another aspect, one shared field is provided on the control channel signal that indicates either a transport format or a redundancy version depending of whether the control channel signal relates to an initial transmission or a retransmission. In another embodiment, further enhancements to a HARQ protocol are suggested for addressing certain error cases.

摘要： Scheduler 304 performs scheduling such that the communication terminal apparatuses to transmit packets to are determined according to the order in CIR information output from demodulator 303, and determines the modulation schemes and coding rates of the packets. Command detector 305 detects an ARQ command transmitted from the communication terminal apparatus determined in scheduler 304, outputs an ACK/NACK signals to buffer 306, and outputs a SUSUPEND signal or a GIVEUP signal to scheduler 304. Scheduler 304 stops retransmission upon receiving a SUSPEND signal or a GIVEUP signal from command detector 305, and redoes the scheduling. Thus, it is possible to improve overall system throughput in a wireless communication system that performs packet transmission.

摘要： This invention relates to a proposal for power headroom reporting for uplink component carriers for which no uplink resource allocation is scheduled by the eNodeB. The user equipment (UE) calculates a virtual power headroom for the non-scheduled uplink component carrier, based on a virtual uplink resource assignment pre-configured by the UE and eNodeB. According to one embodiment the maximum transmit power of the UE is set to a pre-configured fixed value. Alternatively, the maximum transmit power is calculated by the UE considering the power reduction, while the uplink transmission power is set to zero. The virtual power headroom is then transmitted to the eNodeB, which in turn can infer therefrom the pathloss and/or power-per-resource-block for the non-scheduled uplink component carrier and may also infer the power reduction used by the UE. This allows a more accurate scheduling of future uplink transmissions on said non-scheduled uplink component carrier.

摘要翻译： 本发明涉及用于由eNodeB不调度上行链路资源分配的上行链路分量载波的功率余量报告的提案。 用户设备（UE）基于由UE和eNodeB预先配置的虚拟上行链路资源分配，计算非调度上行链路分量载波的虚拟功率余量。 根据一个实施例，UE的最大发射功率被设置为预先配置的固定值。 或者，考虑到功率降低，由UE计算最大发射功率，而上行链路传输功率被设置为零。 然后，虚拟功率余量被发送到eNodeB，其又可以推断出非调度上行链路分量载波的路径损耗和/或每个资源块的功率，并且还可以推断UE使用的功率降低。 这允许对所述非调度上行链路分量载波上的未来上行链路传输进行更精确的调度。
