Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an uplink grant via downlink control signaling for a cell group. The UE may determine an uplink error rate for the cell group based on the downlink control signaling. The UE may identify a radio link failure condition for uplink based on the uplink error rate exceeding an uplink error rate threshold. The UE may transmit a radio link failure indication indicating that the radio link failure condition is based on the uplink error rate. The network may send a cell group reconfiguration message to the UE to release the cell group.

The method also includes comparing a radio frequency condition of the communication between a user equipment and a source access point with a threshold value based on the radio frequency condition and delaying handover procedures for a predefined time based on the comparison, wherein the delaying of the handover procedures occurs when the detected procedure is the qualifying procedure and when the radio frequency condition satisfies a threshold that is based on the threshold value.

In an embodiment, a user equipment (UE) determines that a client application has entered a period of transmission inactivity whereby the UE will not be required to transmit data on behalf of the client application. The UE selectively transmits a transmission inactivity notification to an access network (AN) to notify the AN of the transmission inactivity period. The AN receives the transmission inactivity notification and determines to transition the UE from a first state to a second state based at least in part on the received transmission inactivity notification, the second state associated with lower-power consumption of the UE than the first state. The AN sends instructions to the UE to facilitate the transition of the UE from the first state to the second state. In another embodiment, the AN can send instructions to the UE to prohibit the UE from sending transmission inactivity notifications.

Apparatus and method for generating performance measurements in wireless networks

A terminal obtains a monitored set containing GSM neighbor cells and/or UMTS neighbor cells. The terminal operates in a compressed mode and obtains from a UMTS network at least two transmission gap pattern sequences for different measurement purposes, e.g., for 'GSM carrier RSSI measurements' (GAP), 'GSM initial BSIC identification' (GAP), and &#x201c;GSM BSIC re-confirmation&#x201d; (GAP). The terminal makes RSSI measurements for the GSM cells using multiple transmission gap pattern sequences, e.g., using GAP, GAPand GAP. The terminal identifies the BSIC for at least one GSM cell by (1) detecting the tone on the FCCH using multiple transmission gap pattern sequences, e.g., using GAPand GAP, and (2) decoding the SCH using multiple transmission gap pattern sequences, e.g., using GAPand GAP. The use of multiple transmission gap pattern sequences for RSSI measurement and BSIC identification allows the terminal to complete the cell measurements and send a report sooner, which may improve performance.
