摘要： A method is provided for detection of an uplink grant for a user agent (UA). The method comprises detecting a semi-persistent scheduling (SPS) activation/reconfiguration signaling over a physical downlink control channel (PDCCH) only during an SPS activation window, wherein the SPS activation window precedes a discontinuous reception (DRX) on-duration by a predetermined amount of time. Also included is a UA comprising a component configured to detect an SPS activation/reconfiguration signaling over a PDCCH only during an SPS activation window, wherein the SPS activation window precedes a DRX on-duration by a predetermined amount of time.

摘要： Systems and methods for performing MCS adaptation are provided. In some cases, the network performs MCS adaptation based on received NACKs. In other cases, the mobile station determines an MCS based on channel quality measurements, and feeds back the MCS adaptation decision to the network. In either case, NACK-only feedback may be implemented to reduce interference.

摘要： Systems and methods for signalling transitions between talk-spurt state and silence state for wireless terminals having semi-persistently allocated uplink resources are employed. A layer ½ indication of the state transitions may be transmitted using a resource that is specifically allocated for that purpose. Alternatively, ACK/NACK signalling may be employed. Layer 1 indications may be employed for both state transition types. Alternatively, in-band MAC layer signalling may be used to signal state transition from talk-spurt state to silence, or the network may deduce this state transition on its own. A different uplink wireless transition resource is allocated for the talk-spurt state vs. the silence state.

摘要： A method for communicating channel state information (CSI) to a base station is presented. The method includes identifying a number of allocated resources for CSI within at least one of a Physical Uplink Control CHannel (PUCCH) payload and a Physical Uplink Shared CHannel (PUSCH) payload. The method includes encoding channel state information (CSI) for activated carriers on a user equipment into the allocated resources for CSI. When a number of activated carriers on the user equipment is less than the number of allocated resources for CSI, the method includes using repetition encoding to duplicate the CSI for at least one of the activated carriers on the user equipment into the allocated resources for CSI.

摘要： The present disclosure relates generally to systems and methods for timing synchronization. Uplink synchronization is a necessary component of a UE operating in a mobile, wireless network. Reliable uplink synchronization generally requires regular uplink transmission containing reference signals. A method is provided that defines a burst period for sending the reference signals, determines an interval between the reference signals, and sends a timing instruction message that includes the burst period and the determined interval. A second method is provided that receives the timing instruction message and sends the reference signals in accordance with the timing instruction.

摘要： Supplemental node transmission assistance in a wireless network provides for transmissions between a wireless network and wireless user equipment in a first direction using a serving node of the wireless network while providing for transmissions between the wireless network and wireless user equipment in a second direction using a supplemental node of the wireless network. The supplemental node is selected based on providing better channel conditions between the network and the user equipment in the second direction than the serving node. The supplemental node thus provides transmission assistance for the serving node in order to provide the best available downlink and uplink communications between the user equipment and the network.
