摘要： The invention relates to a method for reporting channel state information from a user equipment (UE) to a eNodeB. In particular, the channel state information report is generated for all component carriers configured by the UE, independent from whether channel state information was actually calculated or not. If no channel state information is calculated for a specific component carrier, then the channel state information encodes information as to the status of said specific component carrier and thus the reason why no channel state information calculation was performed. For instance, the channel state information may encode that the status of the component carrier is deactivated, allowing the base station to check whether a component carrier is indeed activated or deactivated at the UE side.

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方案。 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。

摘要： A base station device causing no decrease in system throughput and guaranteeing the reception quality at a terminal when a DCI directed toward the terminal is mapped to a PDCCH region and an R-PDCCH region. A search space setting unit (103) sets a search space having a plurality of allocation candidates, in both regions. An allocation unit (106) allocates control information to a resource in one allocation candidate in the search space. The ratio of the number of allocation candidates in the R-PDCCH region to the number of allocation candidates in the PDCCH region in the search space for a terminal using DM-RS in the R-PDCCH region is equal to or greater than the ratio of the number of allocation candidates in the R-PDCCH region to the number of allocation candidates in the PDCCH region in the search space for a terminal using CRS in the R-PDCCH region.

摘要： In a wireless relay method for relaying a signal between a base station and a mobile station, if an SRS is transmitted in a subframe immediately previous to the backhaul subframe, the last symbol of an access link subframe is set as a fake symbol in which the SRS that the mobile station transmits to the wireless relay device is not configured. The signal transmitted from the mobile station to the wireless relay device in a previous symbol of one of the fake symbol is received, and switched to transmission from the wireless relay device to the base station. If the SRS is not transmitted in a subframe immediately previous to the backhaul subframe, the signal transmitted from the mobile station to the wireless relay device is received in the last symbol of the access link subframe, and switched to transmission from the wireless relay device to the base station.

摘要： This invention relates to a proposal of an uplink resource assignment format and a downlink resource assignment format. Furthermore, the invention relates to the use of the new uplink/downlink resource assignments in methods for (de) activation of downlink component carrier (s) configured for a base station and a mobile terminal. To enable efficient and robust (de) activation of component carriers, while minimizing the signaling overhead, the invention proposes a new uplink/downlink resource assignment format that allow the activation/deactivation of individual downlink component carriers configured for a mobile. The new uplink or downlink resource assignment comprises an indication of the activation state of the configured downlink component carriers, i.e. indicate which downlink component carrier (s) is/are to be activated or deactivated. This indication is for example implemented by means of a bit-mask that indicates which of the configured uplink component carriers are to be activated respectively deactivated.

摘要： The invention relates to a new structure of a control channel region within a sub-frame of a 3GPP-based based communication system using OFDM in the downlink. This new structure of a control channel region is inter alia particularly suitable for conveying physical downlink control channel information from a donor eNodeB to a relay node. The control channel region is divided in CCEs that have equal size irrespective of the presence of further cell-specific and/or UE-specific reference signals within the control channel region. This is achieved by dividing the control channel region in plural sub-CCEs that are combined to CCEs all having equal size (in terms of resource elements that can be used for the signaling of control information). The control channel region is divided in the frequency domain and/or time domain in a FDM respectively TDM fashion in order to obtain the sub-CCEs

摘要： The present invention relates to a method for balancing the distribution of interference between radio cells in a wireless communication system comprising cells in which subcarrier blocks are used for communication. A number of adjacent cells build a cell cluster. Moreover, the present invention relates to a corresponding method adapted for use in a system in which multi beam antennas or multiple antennas are used. Furthermore, the present invention relates to base stations performing the above method as well as a communication system comprising the base stations. To reduce the large average SIR variations without causing additional SIR estimation, measurement and calculation problem as introduced with power control the invention suggests to group subcarrier blocks into a plurality of subcarrier block sets in each cell of a cell cluster, to determine transmission power ranges for each of the cells of said cell cluster, and to assign transmission power ranges to the subcarrier block sets to perform TPC within the ranges.

摘要： An ARQ (re-) transmission method of transmitting data in a wireless communication system wherein data packets are transmitted from a transmitter to a receiver, using a first transmission and a second transmission based on a repeat request. The method comprises the steps of modulating data at the transmitter using a first signal constellation pattern to obtain a first data symbol. The first data symbol is transmitted as the first transmission to the receiver using a first diversity branch. Further, the data is modulated at the transmitter using a second signal constellation pattern to obtain a second data symbol. Then, the second data symbol is transmitted as the second transmission to the receive over a second diversity branch. Finally, the received first and second data symbol data symbol are diversity combined at the receiver. The invention further relates to a transmitter and a receiver embodied to carry out the method of the invention.
