摘要： There are provided mechanisms for monitoring search spaces. A first method performed by a wireless device comprises receiving an Orthogonal Frequency-Division Multiplexing (OFDM) symbol in a downlink slot. At least part of the OFDM symbol is included in a device-specific search space and in a common search space. The first method comprises monitoring the device-specific search space for at least one device-specific reference signal (RS) and monitoring the common search space for at least one non-device-specific RS. In a second method, a radio access network node transmits an OFDM symbol included in a device-specific search space and in a common search space. The device-specific search space contains a device-specific RS, or the non-device specific search space contains a non-device-specific RS, or both of these apply.

摘要： User equipments, network nodes, and systems are described to transmitting and receiving a physical uplink control channel, PUCCH. For example, a user equipment may receive configuration information from a network node. The configuration information may indicate a plurality of cells available for transmitting or for receiving the PUCCH, the plurality of cells including a reference cell and may indicate a plurality of cell index values respectively associated with a plurality of slots of the reference cell, each cell index value indicating a respective designated cell from among the plurality of cell. The user equipment may receive a timing indicator indicating a reference slot from among the plurality of slots of the reference cell and may transmit the PUCCH using the respective designated cell indicated by the cell index value associated with the reference slot.

摘要： Systems and methods relating to accurate Channel State Information (CSI) measurements for a License Assisted Secondary Cell (LA SCell) are disclosed herein. An exemplary user equipment enabled includes a transceiver, at least one processor, and memory containing instructions executable by the at least one processor whereby the user equipment operates to detect whether a downlink control information (DCI) message indicating that a Channel State Information Reference Symbol (CSI-RS) transmission from an LA SCell of the user equipment is present in a subframe. When the user equipment detects that the DCI message indicates that a CSI-RS transmission from the LA SCell is present in the subframe, it processes a CSI-RS measurement. When the user equipment detects that the DCI message does not indicate that a CSI-RS transmission from the LA SCell is present in the subframe, it refrains from processing the CSI-RS measurement.

摘要： Systems and methods for timing determination for aperiodic Channel State Information (CSI) on Physical Uplink Control Channel (PUCCH) are provided. In some embodiments, a method performed by a wireless device for reporting channel state information includes one or more of: receiving a downlink related Downlink Control Information (DCI) triggering an aperiodic CSI; determining a timing offset for the aperiodic CSI to be reported on PUCCH; and reporting the aperiodic CSI on PUCCH based on the determined timing offset. In this way, efficient and low overhead signaling of timing offset of aperiodic CSI report is enabled.
