摘要： Systems, methods, and apparatuses for sounding reference signal (SRS) management in carrier aggregation (CA) are described. A user equipment (UE) may be scheduled for overlapping (e.g., concurrent) transmissions of SRS and uplink control or data on different cells of a CA configuration. In some cases, the SRS transmission may be dropped (e.g., the UE may refrain from transmitting a scheduled SRS). While in some cases, the UE may transmit both SRS and another uplink message in overlapping time intervals on different cells (e.g., SRS may be transmitted concurrently with another uplink message). A determination of whether to transmit or drop SRS may be based on whether the different cells have different cyclic prefix (CP) lengths or on whether the SRS is scheduled to be transmitted in a special subframe of a time division duplexing (TDD) configuration, for example.

摘要： Aspects of the present disclosure generally relate to wireless communications and, more particularly, to performing channel estimation with modifications for improved system performance. Aspects generally include receiving, at a user equipment (UE), reference signals from a base station in a current subframe, and performing channel estimation, wherein the channel estimation is based at least in part on the reference signals received in the current subframe, a mobility characteristic of the UE, and a configuration of subframes prior to the current subframe..

摘要： Certain aspects of the present disclosure generally relate to wireless communications. In some aspects, a wireless communication device may determine that the wireless communication device is configured to use a primary component carrier (PCC), a first secondary component carrier (SCC), and a second SCC for carrier aggregation. A primary cell may be associated with the PCC, a first secondary cell may be associated with the first SCC, and a second secondary cell may be associated with the second SCC. The first secondary cell may provide control information for the second secondary cell. The wireless communication device may monitor at least one of the first SCC or the second SCC. The wireless communication device may perform an action associated with the second secondary cell based, at least in part, on monitoring the at least one the first SCC or the second SCC.
