    Abstract: A method for reducing power consumption by a wireless communication device is disclosed. The method can include the wireless communication device performing a first measurement of an alternative cell during a first measurement gap; sending a first measurement report generated based on the first measurement to the serving cell; storing the first measurement report; determining a mobility state of the wireless communication device; comparing the mobility state to a mobility threshold criterion; resending the first measurement report to the serving network as a report for a second measurement gap in an instance in which the mobility state satisfies the mobility criterion; and performing a second measurement of the alternative cell during the second measurement gap and sending a second measurement report generated based on the second measurement to the serving cell in an instance in which the mobility state does not satisfy the mobility threshold criterion.

    Abstract: Enabling receive diversity based on detecting incorrect paging message length. A paging channel may be monitored. An indication of a paging message may be received on the paging channel. The paging message may include a message length field indicating a message length of the paging message. The message length field of the paging message may be received on the paging channel and decoded. It may be determined that the message length indicated in the message length field is incorrect. Receive diversity may be enabled for at least one subsequent paging occasion in response to determining that the message length indicated in the message length field is incorrect.

    Abstract: A method performed by stations to transfer call sessions between different access networks. The methods include transmitting, by a first station to a second station, an invite to join a voice call on a first radio access network (RAN), receiving, by the second station, the invite, generating, by the second station, a response to the invite, determining, by the second station, that the response cannot be successfully transmitted to the first station, associating, by the second station, with a second RAN, generating, by the second station, a message indicating the second station has associated with the second RAN, transmitting, by the second station, the message to the first station, retransmitting, by the first station, the invite to join the voice call, receiving, by the second station, the invite on the second RAN and setting up the voice call between the first station and the second station.

    Abstract: User Equipment (UE) based forced inter radio access technology (iRAT) handover. A connection to a network may be established via a first cell operating according to a first radio access technology (RAT). It may be determined to initiate a handover of the UE from the first cell to a second cell operating according to a second RAT. An indication may be transmitted to the network to initiate a handover of the UE from the first cell to the second cell. An indication may be received from the network to perform handover of the UE from the first cell to the second cell in response to the indication to initiate the handover. Handover of the UE from the first cell to the second cell may be performed in response to the indication to perform the handover. Handover may include releasing the connection to the network via the first cell and establishing a connection to the network via the second cell.

    Abstract: This disclosure relates to performing grouped MIMO communications in a cellular communication system. A cellular base station may select a precoding matrix for transmitting a downlink signal to a wireless device via a MIMO channel. The selected precoding matrix may have unequal weights for different MIMO subchannels. The downlink signal may be precoded using the selected precoding matrix. The precoded downlink signal may be transmitted to the wireless device via the MIMO channel. The wireless device may receive and decode the downlink signal.
