摘要： This invention relates to signaling of resource assignments in cross-carrier scheduling scenarios. In order to enable cross-carrier scheduling in a mobile communication system using carrier aggregation while avoiding erroneous detection of assigned physical resources that could lead to HARQ soft buffer corruption/degradation of the system throughput, the invention suggests a scheme for explicitly indicating within downlink control information (DCI) including a resource assignment for the downlink (or uplink) the number of OFDM symbol(s) used for control signaling within a sub-frame on a component carrier on which resources are assigned by the DCI. In one exemplary implementation the number of OFDM symbol(s) used for control signaling is the PCFICH values signaled in a 3GPP LTE-A network. The indication of the OFDM symbol(s) within the sub-frame on the assigned component carrier may for example be jointly encoded with other control signaling information, e.g. with the carrier indication of the carrier indicator field.

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： The invention relates to a method, apparatus and system for configuring control channels in a mobile communication network and a mobile station. In order to suggest another improved scheme for configuring control channels, in particular control channels related to the transmission of user data the invention suggests aligning the size of the control channel information of different formats to an equal number of coded control channel information bits and/or modulation symbols for each control channel. The control channels may comprise scheduling related control information. According to another aspect of the invention, a more flexible solution is proposed that may allow for taking different geometries of mobile stations within a cell into account. Similar to the aspect above, the size of the control channel information is aligned by means of modulation and/or coding, however the control channel information is aligned to one out of a set of numbers of coded control channel information bits and/or modulation symbols for each control channel.

摘要： The present invention relates to providing control information within a search space for blind decoding in a multi-carrier communication system. In particular, the control information is carried within a sub-frame of the communication system, the sub-frame including a plurality of control channel elements. The control channel elements may be aggregated into candidates for blind decoding. The number of control channel elements in a candidate is called aggregation level. In accordance with the present invention, the candidates of lower aggregation levels are localised, meaning that the control channel elements of one candidate are located adjacently to each other in the frequency domain. Some candidates of the higher aggregation level(s) are distributed in the frequency.

In order to allow for an aggregation access point to obtain information on propagation delay differences of downlink transmissions on aggregated serving cells, the invention suggests the mobile terminal to report timing information based on reception time difference information for a the target/reference cell. The mobile terminal performs measurements relating to transmission and/or reception time differences on the target/reference cell, and reports same to the eNodeB. The eNodeB compares the measurement result to a predefined maximum propagation delay time difference.

摘要： A method and receiver for buffering data at the receiver of a packet transmission communication system employing hybrid ARQ types II/III and adaptive coding and modulation schemes, wherein the adaptive coding is performed by a two-stage rate matching algorithm. The idea underlying the invention is to jointly perform the second de-rate matching and the iterative decoding operation. As a result, the buffer conventionally needed upon completion of the second de-rate matching operation can be completely omitted, since the de-rate matching operation is included in the iterative decoding process.

摘要： A method and receiver for buffering data at the receiver of a packet transmission communication system employing hybrid ARQ types II/III and adaptive coding and modulation schemes, wherein the adaptive coding is performed by a two-stage rate matching algorithm. The invention underlies two principal ideas. The first one is based on the recognition that the buffer for storing the incoming data bit stream is only needed temporarily until the first de-rate mapping operation is completed. It can therefore be used afterwards for storing the data bits obtained upon completion of the second de-rate matching operation. This approach helps to reduce the required buffer size at the receiver and also reduces its complexity. The second idea is to utilize the separation of the data bit streams into a plurality of data bit substreams and to input at least one data bit substreams to the decoder without performing a second de-rate matching and storing operation. This is based on the consideration that the decoder may access at least one of the data bit substreams directly from the HARQ buffer. Consequently, the size of the temporary buffer can be reduced also resulting in simplifying the receiver.
摘要翻译：一种用于在采用混合ARQ类型II / III和自适应编码和调制方案的分组传输通信系统的接收机处缓冲数据的方法和接收机，其中自适应编码由两级速率匹配算法执行。本发明是两个主要思想的基础。第一个是基于识别用于存储输入数据比特流的缓冲器仅需要临时直到第一去速率映射操作完成。因此可以随后用于存储在第二去速率匹配操作完成时获得的数据位。这种方法有助于减少接收机所需的缓冲区大小，并降低其复杂性。第二个想法是利用将数据比特流分离成多个数据比特子流，并将至少一个数据比特子流输入到解码器，而不执行第二去速匹配和存储操作。这是基于解码器可以直接从HARQ缓冲器访问至少一个数据比特子流的考虑。因此，可以减小临时缓冲器的尺寸，从而简化接收器。
