Abstract: Methods and apparatus for decoding system information include determining a maximum repetition rate duration based at least in part on a master information block (MIB). The methods and apparatus further include generating a distributed system information block (SIB) decoding scheme for allocating radio frequency resources between a first subscriber identity module (SIM) and a second SIM. In some aspects, the distributed SIB decoding scheme includes a partitioned SIB decoding schedule for the maximum repetition rate duration and based at least in part on a continuous SIB decoding period. Additionally, the methods and apparatus include attempting to decode one or more SIBs during the maximum repetition rate duration according to the distributed SIB decoding scheme.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may adaptively switch between hybrid automatic repeat request (HARQ) monitoring modes to support power savings. In a first HARQ skipping mode, the UE may transmit an uplink message corresponding to a HARQ identifier and may receive a positive acknowledgment (ACK) message in a HARQ monitoring occasion associated with the HARQ identifier. Upon receiving the ACK message, the UE refrains from monitoring a subsequent HARQ monitoring occasion associated with the HARQ identifier while in the first HARQ skipping mode (e.g., an aggressive HARQ skipping mode). The UE may periodically enter a periodic evaluation mode from the first HARQ skipping mode, in which the UE monitors a subsequent HARQ monitoring occasion after receiving an ACK message to check for false ACK messages. If a false ACK message is detected, the UE enters a first HARQ skipping prohibited mode.

Abstract: Methods, systems, and devices for wireless communications are described. A device may identify modes from a set of modes in which at least one modem functional block of a set of modem functional blocks of a chipset operates during a portion of a time interval. Each modem functional block may include a set of units classified to have a power response that satisfies a power trend metric for at least one mode. The device may select power calculation equations from a set of power calculation equations based on the set of multiple modes, calculate an power consumption level for the chipset for the time interval based on the selected power calculation equations and a proportion of the time interval a respective multiple modem functional block of the set of modem functional blocks operates in a respective mode of the set of multiple modes.

Abstract: The present disclosure presents example methods and apparatuses for improved cell searching in a wireless communications environment. For example, the disclosure presents example methods that can include computing a predicted serving signal strength associated with a serving cell where a mobility state of a user equipment is one of a stationary state or a low mobility state. Furthermore, in an aspect, the example method can include ascertaining a search threshold based at least on the predicted serving signal strength and generating a search integration length based on at least the search threshold. In addition, some example methods may include scanning for one or more reselection candidate cells based on at least the search integration length, wherein each of the one or more reselection candidate cells has a cell signal strength greater than the search threshold.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may support dynamic clock switching within a transmission time interval (TTI) to allow for more efficient and flexible processing within the TTI. In particular, a user equipment (UE) may be configured to use multiple clock speeds for processing signals within a TTI, and the UE may determine a clock speed to use for processing data within a TTI based on control information received from a base station. For example, the UE may determine an amount of time available for processing data based on the control information received from the base station, and the UE may adjust its clock speed to finish processing the data in the determined amount of time.

Abstract: The various embodiments include a dual-SIM-dual-active (DSDA) device and methods for implementing robust receive (Rx) processing to resolve radio frequency coexistence interference between two subscriptions operating on the DSDA device. The DSDA device may detect when a subscription (the “aggressor”) de-senses the other subscription (the “victim”) as a result of the aggressor's transmissions, and in response, implement robust Rx processing to mitigate the effects of de-sense on the victim while causing minimal impact to the aggressor.
