摘要： Systems and methods relating to accurate Channel State Information (CSI) measurements for a License Assisted Secondary Cell (LA SCell) are disclosed herein. In some embodiments, a wireless device enabled to operate in a cellular communications network according to a carrier aggregation scheme using both a licensed frequency band and an unlicensed frequency band operates to determine whether a Channel State Information Reference Symbol (CSI-RS) transmission from a LA SCell of the wireless device is present in a subframe, where the LA SCell is in an unlicensed frequency band. The wireless device further operates to process a CSI-RS measurement for the LA SCell for the subframe upon determining that a CSI-RS transmission from the LA SCell is present in the subframe and refrain from processing a CSI-RS measurement for the LA SCell for the subframe upon determining that a CSI-RS transmission from the LA SCell is not present in the subframe.

摘要： A method and network node(600) for providing radio resources in resource blocks in frequency domain in a first system bandwidth (BW1) and in a second system bandwidth (BW2) different than the first system bandwidth and overlapping the first system bandwidth, wherein the first and second system bandwidths have a common frequency centre. The network node(600) applies a number of resource blocks in the first system bandwidth,and appliesan even or odd number of resource blocks in the second system bandwidth when the number of resource blocks in the first system bandwidth is even or odd, respectively. Thereby, an even or odd number of resource blocks is applied in both system bandwidth (BW1, BW2) such that successive resource blocks in frequency are aligned across the first and second system bandwidths (BW1, BW2) which enables full utilization of the potential capacity. The network node further signals an indication of the applied number of resource blocks in at least one of the first and second system bandwidths to at least one mobile terminal(604, 606). (Fig. 6)

摘要： Methods for changing a carrier type from a first carrier type to a second carrier type are disclosed. An example method may be implemented in one or more nodes of a cellular system that includes a plurality of cells that can each be selectively operated with either a first carrier type or a second carrier type, one of the first and second carrier types either having substantially fewer reference symbols than the other or lacking a control structure supported by the other, or both. The example method begins with determining (800) that a cell or cells should be switched from the first carrier type to a second carrier type. This may be done based on, for example, an evaluation of UE performance criteria, e.g., whether one or more UEs are capable of operating on the second carrier type and/or whether one or more UEs may receive a higher quality of service from the second carrier type. The example method continues with changing (810) the carrier type on the cell or cells from the first carrier type to the second carrier type.

摘要： Among other advantageous aspects, the teachings herein provide network-side and device-side apparatuses and methods that preserve normal Resource Element (RE) aggregation levels for the transmission of Enhanced Physical Downlink Control Channels (EPDCCHs) in "constrained" subframes, where "constrained" refers to any subframe having fewer REs available for EPDCCH usage within a base set of PRB pairs than are available in a "non- constrained" or "normal" subframe. Non-limiting examples of "constrained" subframes include special subframes in Time Division Duplex, TDD, operation, which comprise a downlink portion that is abbreviated to accommodate an included uplink portion, along with a guard portion between them. Multimedia Broadcast Single Frequency Network, MBSFN, subframes represent another example of a constrained subframe, where only the first two OFDM symbols within the subframe are available for EPDCCH transmissions.

摘要： PUCCH resource determination for HARQ-ACK transmission in response to ePDCCH-scheduled PDSCH or ePDCCH-indicated SPS release in a TDD radio communication system. Downlink control information (DCI) is received in a downlink subframe via an Enhanced Physical Downlink Control Channel (ePDCCH). A resource index for a Physical Uplink Control Channel (PUCCH) resource is determined, based on the lowest enhanced Control Channel Element (eCCE) index of the received DCI, a device-specific offset value, and an index ithat identifies the downlink subframe in a pre-determined set of one or more downlink subframes associated with an uplink subframe. The PUCCH resource is determined according to a formula that results in a sequential allocation of PUCCH resources in the uplink subframe with respect to the downlink subframes associated with the uplink subframe, for each of a plurality of sets of ePDCCH resources. HARQ feedback is transmitted in the uplink subframe, in the indexed PUCCH resource.

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： Channel-state information and hybrid-ARQ ACK/NACK information for multiple carriers are simultaneously transmitted using a PUCCH Format 3 structure, where the hybrid-ARQ ACK/NACK bits and CSI bits are separately encoded and interleaved. In an example method, a power control offset parameter is calculated (2110) as a linear combination of at least a number N, representing a number of channel-state information bits and a number M, representing a number of hybrid-ARQ ACK/NACK bits. The method continues with the calculating (2120) of a power level for a transmission on a physical uplink control channel (PUCCH), using the power control offset parameter. In some embodiments, encoded channel-state information and hybrid- ARQ ACK/NACK bits are then transmitted (2060) according to the calculated power level. In some embodiments, the linear combination is of the form aN + bM + c, where a, b, and c are non-zero constants.
