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： A network node for demodulating uplink transmissions from a user equipment in a multiple cell communications network can be configured to receive uplink transmissions from the user equipment over a plurality of aggregated cells. The network node transmits, to the user equipment, determined timing advance information for uplink of one or more aggregated cells out of the plurality of aggregated cells. The network node receives, from the user equipment, an uplink transmission of at least one aggregated cell out of the plurality of aggregated cells. The network node then demodulates the received uplink transmission using weighted soft values in periods in the received uplink transmission. The periods are based on the transmitted timing advance information.

摘要： Systems and methods relating to detecting one or more characteristics (e.g., a carrier type or a carrier mode) of a carrier signal transmitted by a radio access node of a cellular communications network are disclosed. In one embodiment, a method of operation of a wireless device includes receiving a carrier signal transmitted by a radio access node and detecting, in the carrier signal, a first physical signal that primarily supports synchronization and cell identification and a second physical signal that supports a functionality other than synchronization and cell identification. A time-domain spacing between the first and second physical signals is a function of a characteristic of the carrier signal. The method further includes determining a characteristic of the carrier signal based on a time-domain spacing between the first and second physical signals detected in the carrier signal.

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： Techniques for supporting both localized and frequency-distributed control channel messages in the same enhanced control channel region are disclosed. An example method begins with receiving (2010) a downlink signal comprising an enhanced control region consisting of at least two sets of physical resource block (PRB) pairs. The method continues with the forming (2020) of one or more distributed enhanced control-channel elements (eCCEs) from a first set of PRB pairs by aggregating physical layer building blocks from multiple PRB pairs to form each distributed eCCE. One or more localized eCCEs are formed (2030) from a second set of PRB pairs by aggregating physical layer building blocks such that each of the localized eCCEs is formed from physical layer building blocks from within a single PRB pair of the second set. Control channel message candidates are formed (2050) from the distributed eCCEs and localized eCCEs, respectively, and decoded (2060).

摘要： According to one aspect of the teachings herein, a set of rules for transmitting Downlink Control Information (DCI) messages containing Transmit Power Control (TPC) commands is known to a wireless communication network (10) and to any number of wireless devices (20) supported by network (10). A device (20) receiving a given TPC DCI message knows the uplink channel(s) to which the received TPC command(s) are to be applied based on interpreting the given TPC DCI message according to the known rules. The rules may be defined as internal within the DCI format, such as bits, states or code points. Additionally, or alternatively, the rules may be defined according to external attributes for DCI message transmission, such as whether the DCI message is transmitted on a Physical Downlink Control Channel, “PDCCH” or on an enhanced PDCCH, “ePDCCH”.

摘要： Systems and methods are disclosed herein for configuring a wireless device individually (i.e., separately) per uplink subframe set as to whether or not the wireless device can use uplink 256 Quadrature Amplitude Modulation (256QAM). In some embodiments, a method of operation of a network node comprises configuring a wireless device for use of a Modulation and Coding Scheme (MCS) table for uplink 256QAM separately per uplink subframe set for two or more uplink subframe sets. In some embodiments, the two or more uplink subframe sets are two or more uplink subframe sets for separate uplink power control. In this manner, 256QAM can be utilized in more subframes and, as a result, uplink data rate can be increased.

摘要： Embodiments herein relate to a communication terminal (10) for handling communication, which communication terminal (10) is being served by a radio access node (12, 13) in a first cell (11) on a carrier of a licensed frequency spectrum and cross-carrier scheduled in a second cell (14) on a carrier of an unlicensed frequency spectrum by the radio access node (12, 13) via the first cell (11). The communication terminal receives an indication that data may be scheduled for the communication terminal (10) on a data channel in the second cell (14). The communication terminal attempts to detect presence of the data channel intended for the communication terminal (10). Then, in case the communication terminal (10) detects presence of the data channel intended for the communication terminal (10), the communication terminal (10) decodes the data channel. In case the communication terminal (10) does not detect presence of the data channel intended for the communication terminal (10), the communication terminal (10) indicates a non-detection of the data channel to the radio access node (12, 13).

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.
