摘要：
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.
