Abstract:
1. A method for operating a user equipment (UE) device as part of a wireless network including a base station, wherein the base station includes a first transceiver for a first sector and a second transceiver for a second sector, the method comprising: receiving two or more subchannel data streams through two or more respective subchannels of a first MIMO channel between the first transceiver and the UE device, wherein the first transceiver includes two or more spatially separated first antennas, wherein the second transceiver includes two or more spatially separated second antennas, wherein the UE device includes two or more spatially separated UE antennas; sending to the first transceiver indicators of signal quality of the two or more subchannels of the first MIMO channel; sending to the second transceiver indicators of signal quality of two or more subchannels of a second MIMO channel, wherein the second MIMO channel is a MIMO channel between the second transceiver and the UE device, wherein the wireless network stops transmitting via a given subchannel of the first MIMO channel and starts transmitting via a given subchannel of the second MIMO channel in response to a determination that the given subchannel of the second MIMO channel has better signal quality than the given subchannel of the first MIMO channel; after the wireless network stops transmission via the given subchannel of the first MIMO channel and starts transmission via the given subchannel of the second MIMO channel, performing operations including: (a) receiving a subset of the two or more subchannel data streams via a subset of the two or more subchannels of the first MIMO channel, wherein the subset does not include the given subchannel of the first MIMO channel; and (b) receiving at least one new subchannel data stream from the second transceiver using at least the given subchannel of the second MIMO channel, wherein (a) and (b) are performed at least partially simultaneously.
