Abstract: A bistable weak PUF circuit with an autonomous stability screening function is provided. The bistable weak PUF circuit includes a decoder, a timing circuit, and a PUF core circuit is provided. The PUF core circuit realizes stable bit screening by connecting two screening levels. When the two screening levels connected to the PUF core circuit are equal, the PUF core circuit generates a W-bit original PUF response in one clock cycle under the control of an m-bit word line level signal output thereto by the decoder. Then, the m-bit word line level signal received by the PUF core circuit is kept unchanged, one of the two screening levels connected to the PUF core circuit is kept unchanged, and the other is reduced by a certain amplitude, and two W-bit screened PUF responses are obtained after the screening levels are exchanged.

Abstract: Aspects relate to carrier aggregation. Selection of an uplink component carrier for carrier aggregation may be flexible in the sense that the frequency band of the uplink component carrier need not be one of the frequency bands allocated for the downlink component carriers. Thus, in some aspects, an uplink component carrier may be decoupled from (e.g., independent of) the downlink carriers. A decision of whether to implement flexible uplink component carrier selection may be based on network traffic (e.g., particular traffic use cases). As one example, the data throughput requirement for downlink traffic may be relatively high, but the component carriers selected for the downlink traffic to provide this throughput might not provide a desired level of service for the uplink traffic. Thus, one or more component carrier bands selected for the uplink traffic may be different from any of the component carrier bands selected for the downlink traffic.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may receive a capability message from a user equipment (UE) based on a number of receive antennas exceeding a number of transmit antennas at the UE. The base station may configure the UE with a mapping between sounding reference signal (SRS) resources and bit sequences, or SRS resource indices (SRIs), based on the capability message. The base station may transmit a control message including one or more SRIs indicating respective SRS resources. The UE may use the one or more SRIs included in a control message from the base station to select respective SRS resources from a resource set. Once the UE selects one or more SRS resources, the UE may transmit one or more SRSs in the SRS resources.

Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for configuring, based on capability of the user equipment (UE) in switching among multiple component carriers (CCs), the UEs for communications with multiple activated CCs. For example, the network may configure the UE with a number of activated CCs that exceeds a number of CCs supported by the UE for simultaneous connections, such that the UE quickly switches among the activated CCs. The UE can thus effectively utilize more operating bands than the number allowed for simultaneous connections using inter-band carrier aggregations.
