摘要： Systems and methods for flexible spectrum, or bandwidth, support in a cellular communications network are disclosed. In one embodiment, a base station for a cellular communications network is configured to transmit a non-standardized bandwidth carrier and information that identifies a standardized bandwidth and additional information that, together with the information that identifies the standardized bandwidth, defines a non-standardized bandwidth of the non-standardized bandwidth carrier. In one embodiment, the additional information defines a bandwidth adjustment for the standardized bandwidth that defines the non-standardized bandwidth. In one embodiment, the bandwidth adjustment is a symmetric bandwidth restriction. In another embodiment, the bandwidth adjustment is an asymmetric bandwidth restriction. In yet another embodiment, the bandwidth adjustment is a symmetric bandwidth expansion. In yet another embodiment, the bandwidth adjustment is an asymmetric bandwidth expansion.

摘要： The set of resource aggregation levels available for forming an enhanced control channel message may vary from one subframe to another, based on the level of puncturing in the transmitted subframes. An example method begins with determining members of a set of aggregation levels usable to aggregate the non-overlapping subsets of resource elements for transmitting downlink control information. This determining is based on a puncturing level to be used for the transmission of the downlink control information. Downlink control information for the given subframe is mapped to one or more non-overlapping subsets of resource elements in the at least one block of time-frequency resources, according to an aggregation level selected from the determined set, and then transmitted, in the one or more non-overlapping subsets. This method may be repeated for each of several subframes, where the puncturing may differ from one subframe to another.

摘要： A method of operating a wireless communication terminal includes receiving one or more downlink control messages that each contain scheduling information scheduling the wireless terminal to receive a downlink transmission on either a primary carrier or a secondary carrier. The method also includes determining, for each of the downlink control messages, whether that message includes scheduling information for the primary carrier or for a secondary carrier. Additionally, the method includes selecting a format for an uplink control message based on whether any of the downlink control messages includes scheduling information for a secondary carrier, generating an uplink control message based on the selected format, and transmitting the uplink control message to the base station.

摘要： A method and a radio base station for interleaving control channel data to be transmitted in a telecommunications system are described. The method comprises grouping the control channel elements CCE1-CCEn into a first order of control channel symbol groups, adding symbol groups comprising dummy values or zeros to the first order of control channel symbol groups based on a number of available symbol group positions for the shared control channel, interleaving the first order of the control channel symbol groups resulting in an a second order, and mapping the second order of control channel symbol groups to the available control channel transmission resources.

摘要： A method and radio node for radio communication of data with a User Equipment (UE) wherein a first carrier type A is applicable for serving both legacy UEs and new UEs and a second carrier type B is applicable only for serving new UEs, and wherein the UE is configured to support both the first and second carrier types A, B. The radio node applies the first carrier type A for downlink signals on a first frequency, and switches between the second and first carrier types B, A for downlink signals on a second frequency in order to allow the legacy UEs to measure and/or be served on the second frequency. The radio node further transmits to the UE an indicator in a downlink assignment for data on a data channel, the indicator indicating to the UE whether Cell-specific Reference Signal (CRS) resource elements are used for transmitting the data to the UE. Thereby the UE is enabled to determine a mapping for the data channel depending on the indicator.

摘要： A method in a communication node for mapping symbols of an Enhanced Physical Downlink Control Channel, EPDCCH, message is provided. The EPDCCH comprises one or more aggregation levels. For each aggregation level, an EPDCCH message is constituted by a set of Control Channel Elements, eCCEs. Each eCCE is mapped to a set of multiple enhanced Resource Element Groups, eREGs, wherein each eREG is a group of Resource Elements, REs, in a Physical Resource Block, PRB, pair. The communication node maps the symbols of the EPDCCH message to the set of REs that constitutes the multiple eREGs that the set of eCCEs correspond to. The order in which the EPDCCH symbols are mapped to the set of REs is dependent on the aggregation level.

摘要： In one aspect, the teachings herein provide a method and apparatus for extending certain HARQ feedback procedures introduced in LTE Rel-10, which were defined for CA configurations involving TDD serving cells of the same UL/DL configuration, to the new, more complex CA configurations introduced in Rel-11, which involve the aggregation of interband TDD serving cells with differing UL/DL configurations. Such reuse enables reliant and efficient HARQ feedback signaling in LTE Rel-11, without substantially increasing the specification or implementation complexity of HARQ feedback signaling in LTE Rel-11, despite the decidedly more complex CA configurations introduced in LTE Rel-11.
摘要翻译： 在一个方面，本文的教导提供了一种用于扩展在LTE Rel-10中引入的某些HARQ反馈过程的方法和装置，其将针对涉及相同UL / DL配置的TDD服务小区的CA配置定义到新的更复杂的CA 在Rel-11中引入的配置涉及具有不同UL / DL配置的带间TDD服务小区的聚合。 尽管在LTE Rel-11中引入了明确更复杂的CA配置，但是在LTE Rel-11中，这种重用能够在LTE Rel-11中实现依赖和高效的HARQ反馈信令，而不会基本上增加LTE Rel-11中HARQ反馈信令的规范或实施复杂度。
