    摘要： A wireless device is configured to select a beam and/or an antenna based on detection a detected position and/or orientation of the device relative to a remote device. The device obtains motion data indicating a change in position or orientation of the wireless device. The device determines its pose relative to the remote device. The device accesses a coverage map that associates, for each potential pose for the device with respect to the remote device: an antenna for communicating with the remote device and/or a beam for communicating with the remote device. The device selects a particular antenna and/or a particular beam for communicating with the remote device; and causes transmission or reception of data to or from the remote device by the particular antenna and/or the particular beam.

    摘要： 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.

    摘要： A method for network reselection by a wireless communication device is provided. The wireless communication device can have an established connection to a first network. The method can include measuring a signal strength and a signal-to-noise ratio of the first network. The method can further include determining that the signal strength satisfies a signal strength threshold. The method can additionally include comparing the signal-to-noise ratio to a signal-to-noise ratio threshold. The method can also include disconnecting from the first network and reselecting to a second network in an instance in which the signal-to-noise ratio does not satisfy the signal-to-noise ratio threshold even though the signal strength satisfies the signal strength threshold.

    摘要： A user equipment (UE) configured to connect to a network and operate in a carrier aggregation mode and a single carrier mode performs methods to select optimal component carriers. The methods include determining that a primary component carrier is operating less optimally than a secondary component carrier, sending an indication to the network that the primary component carrier is operating less optimally than the secondary component carrier, acquiring the secondary component carrier as a target primary component carrier and operating with the secondary component carrier as the target primary carrier component. In one exemplary embodiment, the indication is declaring a radio link failure (“RLF”) between the UE and the network. In another exemplary embodiment, the indication is a measurement report send to the network that triggers a handover procedure for the UE.
