In accordance with some embodiments, a method may include transmitting, by a source network entity, at least one handover prepare request comprising at least one extension indication to a target network entity. The method may further include receiving, by the source network entity, in response to the at least one handover prepare request, at least one handover request response from the target network entity. The method may further include transmitting, by the source network entity, at least one handover command acknowledgement to at least one user equipment based upon the at least one handover request response.

Enhanced method for preparing conditional handover to avoid preemption

A first method (and related first apparatus) includes transmitting, in a handover request message, an indication of a first protocol version; a second method (and related second apparatus) includes receiving, in the handover request message, the indication, deciding, based on the received indication and a second protocol version, on a value of an information element included in a handover request acknowledgement message to be transmitted, the information element indicating usage of a first or second signaling scheme, and transmitting the handover request acknowledgement message including the information element; and in the first method receiving the handover request acknowledgement message including the information element; and a third method (and related third apparatus) including receiving the handover command message including the information element, and configuring according to one of the first and second signaling schemes indicated by the information element.

Methods, apparatuses, related computer program product and data structure for deciding on a signaling scheme for handover

Methods, apparatuses, and systems are provided for modem coordination. A method may include establishing a coordinated communication session with a base station on a first communication channel. The method may further include causing transmission, to the base station, of an indication of an occurrence of an irregular transmission of data on a second communication channel. The second communication channel may be with a station logically separated from the base station. The base station maybe configured to respond to the indication of the occurrence of the irregular transmission by modifying transmission on the first communication channel to avoid interfering with the irregular transmission. The method may additionally include causing transmission, to the base station, of an indication of completion of the irregular transmission to allow the base station to resume normal transmission on the first communication channel. Corresponding apparatuses and systems are also provided.

Systems, methods, and apparatuses for modem coordination

In accordance with an example embodiment of the present invention, a method is disclosed that comprises signaling by a user equipment (UE) to indicate a support for at least a second frequency band mode in addition to a first frequency band mode, wherein the first frequency band mode and the second frequency band mode have at least one overlapping frequency channel; and receiving from a base station at least one resource allocation message to allocate at least one of a downlink channel and an uplink channel that complies to at least one of a plurality of radio frequency (RF) restrictions of the second frequency band mode.

Apparatus and method for interworking between multiple frequency band modes

A first method (and related first apparatus) includes transmitting, in a handover request message, an indication of a first protocol version; a second method (and related second apparatus) includes receiving, in the handover request message, the indication, deciding, based on the received indication and a second protocol version, on a value of an information element included in a handover request acknowledgement message to be transmitted, the information element indicating usage of a first or second signaling schemes, and transmitting the handover request acknowledgement message including the information element; and in the first method receiving the handover request acknowledgement message including the information element; and a third method (and related third apparatus) including receiving the handover command message including the information element, and configuring according to one of the first and second signaling schemes indicated by the information element.
