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.

Abstract: A control resource region of an New Radio system slot structure may be separated into control resource sets, only some of which may be used for control transmissions. Aspects presented herein improve the efficient utilization of resources by enabling data transmission in resources of the DL control resource region and/or the UL control resource region. A UE receives an indication of a control resource set in a control resource region of a slot that may provide a control channel resource or a data channel resource and performs rate matching for data transmissions in the data channel based at least in part on the indication. The indication may be a semi-static indication, e.g., RRC signaling, of the control resource set.

Abstract: Methods and devices are disclosed for implementing opportunistic mobile receive diversity (“OMRD”) on a multi-SIM wireless device. The wireless device may receive a request from a protocol stack associated with the first SIM to utilize the second RF resource for receive diversity, and determine whether a protocol stack associated with the second SIM currently has a lower priority than the protocol stack associated with the first SIM. Upon determining that the protocol stack associated with the second SIM currently has a lower priority than the protocol stack associated with the first SIM, the wireless device may grant control of the second RF resource to the protocol stack associated with the first SIM. Granting control may provide, to the protocol stack associated with the first SIM, a capability to enable and disable receive diversity using the first and second RF resources.

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

Abstract: A UE may be configured to communicate using one of analog beamforming or hybrid beamforming. The UE may receive a set of beamformed signals from a base station. The UE may determine a set of angular spread values associated with a set of clusters in a channel between the base station and the UE based on the set of beamformed signals received from the base station. The UE may transmit the set of angular spread values to the base station. The UE may receive, from the base station based on the set of angular spread values, a set of transmission ranks associated with at least one cluster of the set of clusters. The UE may communicate at least one data stream with the base station across the at least one cluster using the set of transmission ranks associated with the at least one cluster of the set of clusters.
