A process for dual subscriber identity module (SIM) dual standby (DR-DSDS) operation including receiving event data indicating a trigger event configuring radio frequency (RF) hardware; identifying a conflict between a communication band of a first SIM and a communication band of a second SIM for DR-DSDS operation; determining a type of the conflict; determining, a first priority value for a component carrier (CC) corresponding to the first SIM, and a second priority value for a CC corresponding to the second SIM, the first and second priority values based at least on the type of the conflict; determining a timing scenario for configuring the RF hardware; searching for a RF hardware configuration to resolve the conflict based on the first and second priority values; and generating RF handle data, corresponding to the conflict resolution, specifying a RF hardware configuration for the DR-DSDS operation.

Band conflict resolution for dual receive dual sim dual standby scenarios

A user equipment (UE) configured for discontinuous reception (DRX) operation, is disclosed. The UE comprises one or more processors configured to perform a static DRX update by aggregating all DRX timers configured for the UE during each slot of one or more consecutive slots associated with a radio frame structure, until it is determined that all the DRX timers are expiring in a select slot of the one or more consecutive slots. The one or more processors is further configured to compute an end of DRX active time, upon performing the static DRX update in the select slot; and perform a dynamic DRX event aggregation responsive to determining that all DRX events associated with physical downlink control channel (PDCCH) monitoring occasions (MOs) within the computed end of DRX active time have not been received.

Method and apparatus for optimal user equipment (UE) power consumption in new radio (NR) connected discontinuous reception (C-DRX) mode

Aspects provide techniques and apparatus for wireless communications (e.g., for saving power when performing control channel processing when in an idle mode or in a 'PDCCH only' in connected mode). An exemplary method includes performing, using a processor, a first type of control channel processing in a first connection state using a firmware image stored in internal memory of the processor, wherein performing control channel processing comprises accessing memory external to the processor, determining one or more conditions for entering a low-power mode (LPM) associated with the processor are satisfied, entering the LPM based on the determination, wherein entering into the LPM includes at least one of disabling or disallowing access to the external memory based on entering the LPM, and performing, using the processor, a second type of control channel processing using the firmware image stored in internal memory of the processor based on entering the LPM.

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.

Method and device for implementing radio frequency coexistence management strategy in wireless devices

The various embodiments include a dual-SIM-dual-active (DSDA) device and methods for implementing pipelining of operation registration data and conflict checking to predict radio frequency co-existence interference between two subscriptions operating on the DSDA device. The DSDA device may predict when a subscription (the 'aggressor') de-senses the other subscription (the 'victim') as a result of the aggressor's scheduled operations, by analyzing the conflicting operation registration data prior to the scheduled operation execution time. The operation registration data is received and analyzed close in time to the scheduled execution of the operation to limit the possibility of changes in the operation schedule and registration data.

Pipelining registration and conflict detection in dual-SIM-dual-active communication device coexistence

Methods for enabling a mobile device to efficiently resolve coexistence issues in a DSDA configuration by utilizing a feed forward strategy to avoid hand-shaking between software-implemented operations and firmware. The mobile device may employ a dual subscription, dual active (or 'DSDA') configuration in which two or more subscriptions may be associated with concurrently active communications, such as voice or data calls. The mobile device may be configured to predict activity associated with the concurrently active subscriptions, such as determining operations likely to be performed in a future time period. Such predicted activity information, as well as predefined actions and priority information, may be provided to a library common to both subscriptions. Firmware of the subscriptions may use the common library to detect current conflicts, such as desense, as well as actions to perform to resolve coexistence issues, such as blanking operations.

Software feed forward strategy to avoid hand-shaking delays between software and firmware

A method for estimating timing in a wireless communication comprises the steps of receiving a plurality of symbol bursts corresponding to a plurality of time slots and selecting a subset of symbols from a first symbol burst of the plurality of symbol bursts. The subset comprises a first midamble symbol. The method further comprises the steps of calculating, for each symbol in the subset, a corresponding midamble estimation error, and determining the lowest calculated midamble estimation error to determine a timing for the first symbol burst. The method further comprises the steps of processing the first symbol burst utilizing the timing determined for the first symbol burst, and processing a second symbol burst of the plurality of symbol bursts utilizing the timing determined for the first symbol burst.
