Sounding reference signals with collisions in asymmetric carrier aggregation
摘要
說明書
The SRS transmissions may be split in any number of divisions between component carriers. The configuration and/or activation of SRS transmissions can be jointly or separately managed among component carriers. As an example, two separate configurations of SRS transmissions can be provided to a user equipment for two component carriers, where the two configurations may or may not have overlapped SRS transmission instances. The carrier aggregation 700 illustrates a uniform split among the component carriers. However, non-uniform divisions are also contemplated in various alternative aspects.
In order to transmit the SRS during the inactive uplink portion of DL CC2, the UE may need to switch, also referred to herein as “retune”, from a different CC. The switch may be from an uplink transmission, e.g., on CC1, or potentially a switch from a different CC that is configured to receive a downlink transmission during the period of time that the UE will transmit the SRS resulting in an interruption of the other transmission.
