Abstract: Aspects of the present disclosure provide wireless communication devices and methods configured to operate with multiple active connections. A user equipment establishes a first active connection associated with a first subscription. The user equipment also establishes a second active connection, simultaneous to the first active connection, associated with a second subscription. The user equipment provides modem information corresponding to connection qualities of the first active connection and second active connection, to an operating system of the user equipment. Furthermore, the user equipment mitigates contention between the first active connection and second active connection by degrading at least one of the first active connection or second active connection in accordance with a decision given by the operating system based on the modem information.

Abstract: Access terminals are adapted to facilitate discontinuous transmission (DTX) employable during active transmissions. According to one example, an access terminal may be actively transmitting a plurality of frames on a reverse link channel. The access terminal can autonomously implement a DTX operation during the active reverse link transmissions, in which a transmitter circuit is powered down for periods of time less than a duration of one frame. As a result, reverse link transmissions are punctured during the powered down periods. Other aspects, embodiments, and features are also included.

Abstract: Distributed antenna systems (DASs) can include a plurality of spatially separated remote antenna units. According to at least one example, a first group of remote antenna units can simulcast downlink transmissions on a first carrier with a particular sector identity (ID). A second group of remote antenna units, including at least one different remote antenna unit from the first group, can simulcast downlink transmissions on a second carrier with the same sector ID. According to at least one other example, two or more remote antenna units which include respective coverage areas that are non-adjacent to one another can be employed to simulcast downlink transmissions.

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 transmit chain may be used to transmit uplink traffic associated with the first call and uplink traffic associated with the second call.

Downlink traffic associated with the first and second calls may be received using different receive chain. Downlink traffic associated with the first and second calls may be received using the same receive chain.
