Abstract: Apparatus and methods are provided to enable a ratcheting of uplink transmit power at an access terminal in a wireless communication network, such that the transmit power is maintained between an upper threshold and a lower threshold. Here, the decision whether to ratchet the power may be based on one or both of the open-loop transmit power and/or the closed-loop transmit power. Moreover, the decision whether to ratchet the transmit power may be based on the power per carrier in a multi-carrier wireless communication network. Other aspects, embodiments, and features are also claimed and described.

Abstract: Allocating transmit power among two or more carriers assigned to a wireless communication device is disclosed. In one aspect, a method of allocating transmit power includes determining a total amount of data transmit power available at the wireless communication device for data transmission over the carriers. An efficiency metric is determined for each carrier based on the carrier's transmission characteristics and a portion of the total data transmit power is allocated to each carrier based on each carrier's efficiency metric.

Abstract: A method, an apparatus, and a computer program product are provided. The apparatus may be configured to establish a first call for a first subscription, and accept a second call for a second subscription while maintaining the first call. A single RF transmit chain may be scheduled for uplink transmissions associated with the first call and uplink transmissions associated with the second call. A timesharing schedule for the transmit chain may determine timing for the uplink transmissions associated with the first call is transmitted and when the uplink transmissions associated with the second call is transmitted on the transmit chain. Downlink transmissions associated with the first and second calls may be received using different receive chain. Downlink transmissions associated with the first and second calls may be received using the same receive chain.

Abstract: An access terminal configured to enable communication with two or more wireless communications networks simultaneously. According to some aspects of the disclosure, an access terminal (e.g., dual- SIM access terminal) can be active simultaneously on both networks with reduced interference between transmission and reception. A number of different techniques for mitigating desense on a victim's Rx are illustrated in this disclosure with a GSM aggressor and an EV- DO victim as non-limiting examples. According to an embodiment, modifying a preamble detection process of the second data at the second radio access circuit based on the transmitting time period. According to another embodiment, estimating a percentage of second data to be interfered by the transmission of the first data during the transmitting time period, the second data being to be received using a second radio access circuit of a second RAT, determining an effective signal-to-noise ratio (SNR) based on the estimated percentage and sending a DRC request based on the effective SNR using the second radio access circuit. According to another embodiment, suspending handling of at least one corrupted forward link MAC channel at the second radio access circuit during the transmitting time period. According to another embodiment, storing the second data in a memory, determining a desense value indicative of a degree of desense on the reception of the second data caused by the transmission of the first data, and selectively nulling the second data in the memory based on the desense value.

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.
