20110111765 | SYSTEM AND METHODS FOR TRAFFIC VOLUME REPORTING DURING RADIO ACCESS NETWORK CONNECTION SETUP - Disclosed are systems, methods and computer program products for traffic volume reporting during radio access network (RAN) connection setup. In one aspect, the RAN broadcasts an indicator that it accepts traffic volume measurements (TVM) from access terminals (ATs) and an associated TVM threshold. An AT measures its traffic volume before requesting a connection with the RAN. If the traffic volume is above the threshold, AT transmits to the RAN a connection request containing a TVM indicator that the measured traffic volume from the AT is above the threshold. If the traffic volume is below the threshold, AT transmits to the RAN a connection request containing a TVM indicator that the traffic volume is below the threshold. | 05-12-2011 |

In one example, a user equipment (UE) is equipped to obtain a received signal code power (RSCP) value and a load factor value for each of one or more cells.

20130176866 | CALL RECOVERY IN TD-SCDMA HANDOVER FAILURE - A method of wireless communication includes measuring and recording a path loss of a first downlink signal from a source base station, prior to attempting handoff from the source base station to a target base station. The path loss of a second downlink signal from the source base station is measured after unsuccessful handoff from the source base station to the target base station. A UE communicates with the source base station, after unsuccessful handoff, using an uplink timing corresponding to an uplink timing recorded prior to attempting handoff when a difference between the path loss of the first downlink signal and the path loss of the second downlink signal fails to meet a threshold value. A new uplink timing is used when the difference meets the threshold value. | 07-11-2013 |
20130201885 | Short Random Access Channel (RACH) Disabling in TDD-LTE - In TDD-LTE wireless systems, an additional fourth preamble for the random access channel, called short RACH, may be used. If short RACH signaling is to be used, the random access preamble is transmitted in the uplink pilot time slot (UpPTS) field in the special subframe. The location of the uplink pilot time slot (UpPTS) is next to a downlink subframe. Therefore, interference from neighbor base stations may interfere with the short RACH preamble within the uplink pilot time slot. The interference to the short RACH will prevent the eNodeB from detecting the short RACH preamble and thus prevent the UE from accessing the network. An interference level on an Uplink Pilot Time Slot (UpPTS) may be measured and when the interference level exceeds a threshold value a User Equipment (UE) is instructed to disable short Random Access Channel (RACH) signaling. The UE may then be instructed to enable normal RACH. When the interference level falls below the threshold value the UE is instructed to resume short RACH signaling | 08-08-2013 |

20130329575 | CHANNEL QUALITY REPORTING - In certain communication systems, such as TD-HSDPA communications, channel quality index (CQI) reporting is based on a predetermined configuration, such as a mobile device (UE) reporting a CQI for a most recently received data transmission. This configuration may lead to errors if a UE reports a CQI for a certain data transmission but the base station (node B) believes the CQI corresponds to a different data transmission, such as a later transmission the UE never received due to an error processing control channel information. Offered is an indicator to accompany CQI reports. The indicator indicates to the node B which communication resource corresponds to the CQI report. | 12-12-2013 |
20130336293 | SCHEDULING INFORMATION REPORTING IN TD-HSUPA SYSTEMS - A method to improve the sending of scheduling information, particularly for Time Division-High-Speed Uplink Packet Access (TD-HSUPA) operation is described. When T-WAIT is configured at a large value which is above a threshold, and when the UE transitions from having a grant to not having a grant, and the TEBS is larger than zero, if the UE does not receive a grant within a time window, the UE may send scheduling information via the E-RUCCH without waiting for the T-WAIT timer to expire. | 12-19-2013 |

The adjustment may be based on the UE's remaining battery power. When the battery power level is low, the threshold is increased to reduce false detections. When the battery power level is high, the threshold is decreased to increase the likelihood of detecting the signal on a paging indicator channel. | 05-01-2014 |
20140140223 | INTER RADIO ACCESS TECHNOLOGY (IRAT) MEASUREMENT - A user equipment (UE) may perform an inter radio access technology (IRAT) measurement in time slots not deemed to be carrying critical data. In such instances, the UE only transmits and decodes critical data in the critical time slots when a serving cell signal is low for a determined period of time. Otherwise, when the time slots do not carry critical data, i.e., non-critical time slots, the UE stops transmitting and decoding and uses the non-critical time slots for IRAT measurement. | 05-22-2014 |
20140140226 | IRAT MEASUREMENT REPORTING METHOD IN TD-SCDMA - A user equipment (UE) considers both the signal strength in time slot zero and the signal quality of the downlink traffic time slots when determining whether to send an IRAT measurement report to trigger IRAT handover to GSM. | 05-22-2014 |
