Abstract: In a carrier aggregation or EN-DC scenario, there exist multiple different conditions based on which UE would benefit from a higher or lower grant ratio on a specific carrier as opposed to other carriers. There are a number of criteria based on which UE may select a preferred carrier for uplink grant reception. Some example criteria include self-jamming conditions, thermal constraints, and inter-RAT interference. These and other criteria may form a basis for identifying preferred carriers, non-preferred carriers, or ranking carriers. Various embodiments described provide techniques for a UE to indicate preferred and non-preferred carriers to a serving base station. A serving base station, in turn, can make use of the indication to adjust the ratio at which uplink transmissions are scheduled on these carriers.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus relating to intelligent resource assignment to increase throughput in LTE multiple input multiple output (MIMO) and carrier aggregation (CA) capable devices. In certain aspects, a MIMO and CA capable wireless communication device communicates with a base station (BS) on multiple component carriers (CCs) through multiple radio frequency (RF) chains. In such aspects, the device tentatively switches one or more first RF chains, not assigned to a first CC of the multiple CCs, to the first CC for evaluating a rank of the first CC. The device then determines that the first CC has a higher rank indication (RI) with the one or more RF chains. The device subsequently evaluates one or more performance factors, in conjunction with the higher rank, based on which the device then additionally assigns one or more second RF chains to the first CC.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may tune a first voltage controlled oscillator (VCO) to an offset frequency from a particular frequency, wherein the offset frequency differs from the particular frequency by an offset, wherein the offset is based at least in part on at least one parameter, and wherein the UE is configured to operate in an at least one carrier mode associated with at least one time division duplexed carrier; and communicate, while the first VCO is tuned to the offset frequency, a communication associated with a second VCO, wherein the second is tuned to the particular frequency. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a power reduction configuration associated with uplink communications performed by the UE within aggregated carriers, and a resource allocation for communicating one or more uplink messages across multiple aggregated carriers (e.g., uplink carrier aggregation (ULCA)). The UE may evaluate power reduction values that are to be used for the multiple aggregated carriers based on the power reduction configuration, and may determine throughput contributions for each respective carrier. Based on the power reduction values and the throughput contributions of the respective carriers, the UE may determine whether to continue operating according to the resource configuration for ULCA, or to revert to single-carrier communications.
