摘要

An apparatus may use inactive uplink portions of a downlink CC to transmit SRS to an eNB. At times there may be a collision between the SRS transmission and uplink transmissions or downlink transmissions on another CC. The apparatus receives a carrier aggregation configuration for a first downlink CC and a second CC, determines to transmit an uplink transmission on the second CC or to receive a downlink transmission on the second CC, determines that the SRS would at least partially collide with the uplink transmission or the downlink transmission, and determines to adjust at least one of the uplink transmission, the SRS transmission, or reception of the downlink transmission based on the determination of the collision and an interruption time to transmit the SRS in the uplink portion of the first CC.

說明書

The apparatus may include additional components that perform each of the blocks of the algorithm in the aforementioned flowcharts of FIGS. 12-15. As such, each block in the aforementioned flowcharts of FIGS. 12-15 may be performed by a component and the apparatus may include one or more of those components. The components may be one or more hardware components specifically configured to carry out the stated processes/algorithm, implemented by a processor configured to perform the stated processes/algorithm, stored within a computer-readable medium for implementation by a processor, or some combination thereof.

FIG. 17 is a diagram 1700 illustrating an example of a hardware implementation for an apparatus 1602′ employing a processing system 1714. The processing system 1714 may be implemented with a bus architecture, represented generally by the bus 1724. The bus 1724 may include any number of interconnecting buses and bridges depending on the specific application of the processing system 1714 and the overall design constraints. The bus 1724 links together various circuits including one or more processors and/or hardware components, represented by the processor 1704, the components 1604, 1606, 1608, 1610, 1612, 1614, 1616, 1618, and 1620, and the computer-readable medium/memory 1706. The bus 1724 may also link various other circuits such as timing sources, peripherals, voltage regulators, and power management circuits, which are well known in the art, and therefore, will not be described any further.
