摘要： Wireless communication devices with multiple receive (RX) chains may be operated to maintain high performance while saving power. This may be accomplished by evaluating signal strength during transmission of the RX packets, and/or evaluating a possible imbalance (gain difference) between the multiple RX chains within the wireless communication device. Signal strength (or good signal) detection may be enabled when non-MIMO (non-multiple-in-multiple-out) transmissions are taking place, while imbalance detection (antenna gain comparison) may be enabled when a specified number of single-stream packets have been received. Once the decision has been made to operate in a reduced number RX path mode, decision to reactivate one or more additional RX paths may be made based on MIMO detection, a detection of a drop in signal quality, and/or upon expiration of a power save timer.

摘要： Methods and apparatus for synchronizing operational state during hybrid network operation. In one embodiment, the various access technologies that makeup the hybrid network not fully synchronized. Thus, a wireless device operating in a mixed mode must be capable of managing synchronization across multiple access technologies. The wireless device is configured to estimate an expected “tune-away” period when disengaging with a one access technology to address events (for example, link maintenance, calls, data, and the like) or perform monitoring on a second access technology. The estimate is then used by the device to adjust its operational parameters on the technology from which it is tuning away. This ensures smooth switching away from and back to the various network technologies.

摘要： Mobile devices, base stations, and/or relay stations may implement a method for an improved and reliable automatic repeat request feedback indication. A mobile device (UE) may establish communication within a wireless network, and indicate to the network that the UE is a special type device, e.g. a constrained device. The network (base station) may then not send an indication on a physical indicator channel to the UE when certain conditions are met, and instead, the mobile device may interpret control information received from the network on a physical control channel as a negative acknowledgment indication corresponding to an automatic repeat request from the network. The UE may then perform a retransmission according to the interpreted control information. A new control information format may be used to further define how the network and UE implement the automatic repeat request process, to reduce the total number of bits required in the control information.

摘要： A user equipment (UE) and base station may implement improved communication methods which enable a UE that is peak current limited to perform UL transmissions which are consistent with the UL timeline. A UE that is peak current limited may utilize a new form of distributed TTI (transmit time interval) bundling for improved uplink communication performance. In performing “distributed” TTI bundling, the UE may transmit a plurality of redundancy versions of first information to the base station, wherein the plurality of redundancy versions are transmitted in non-consecutive sub-frames with a periodicity of X ms. After the plurality of redundancy versions of first information are transmitted to the base station, the base station may provide a single acknowledge/negative acknowledge (ACK/NACK) to the UE. A method for dynamically generating and using a bundle size for TTI bundling is also disclosed.

摘要： This disclosure relates to techniques for a link budget limited UE to improve communications performance with a cellular network. The UE may perform signal to interference noise ratio (SINR) measurements and use these measurements to adjust a received signal power value that is provided to the cellular network as a received signal power measurement. The UE may generate the received signal power value based at least in part on the SINR measurement in order to reduce the likelihood of handover when the UE has good SINR but poor received signal power. The UE may also provide preferred configuration information to the base station which enhances the performance of the UE when link budget limited. The configuration information may specify one or more parameter values designed to provide improved performance for a link budget limited device.
