The UE will receive an indication from a node B to measure a signal quality on one of a number of carrier frequencies in the network. The UE will then measure the signal quality on the carrier frequency based on measurements using a downlink synchronization code transmitted by the node B on the downlink pilot channel of the carrier frequencies in the multicarrier network. The UE may then report the channel quality back to the node B. | 11-10-2011 |
20110280131 | High Speed Control Channel Monitoring in a Multicarrier Radio Access Network - User equipments (UEs) will monitor each frequency in a multicarrier wireless radio access network for at least one control channel that may contain downlink data allocations or other such messages from the network. This monitoring may be dynamically controlled with a physical layer indication received by the UE from a node B that designates a number of carrier frequencies of all of the carrier frequencies of the network.

Scheduled transmissions during a UE's idle interval result in lost system resources because the transmissions do not occur. A NB may prevent conflicts between scheduled transmissions and a UE's idle period by prohibiting transfer of certain channels a predetermined number of radio frames before the UE's idle period. Alternatively, the NB may schedule transmission of certain channels with a predetermined delay to prevent the channels from being scheduled during the UE's idle period. | 11-17-2011 |

Before handover, a multimode UE may receive an indication from a serving TD-SCDMA cell to enter a Discontinuous Reception (DRX) mode and perform measurement on a nearby GSM cell. After measurement, the UE receives a grant from the serving TD-SCDMA cell allowing the UE to transmit a measurement report to the serving TD-SCDMA cell. The TD-SCDMA cell may use the measurement report to determine if the multimode UE should handover to the GSM cell. | 11-17-2011 |
20110280221 | Discontinuous Reception (DRX) For Multimode User Equipment (UE) Operation - In geographical areas with incomplete coverage of Time Division Synchronous Code Division Multiple Access (TD-SCDMA) networks, it may be beneficial for a multimode User Equipment (UE) to register with and monitor paging channels of a Base Transceiver Station (BTS) of a Code Division Multiple Access (CDMA) 1× Radio Transmission Technology (RTT). The UE may monitor the paging channels of the BTS of the CDMA 1× RTT network by entering discontinuous reception (DRX) from the Node B of the TD-SCDMA network. The Node B of the TD-SCDMA network schedules the UE's DRX to coincide with the paging interval appropriate for the UE determined by the UE's IMSI and network time information. After monitoring the paging channel, the UE reacquires the Node B of the TD-SCDMA network and receives data and HARQ transmissions. | 11-17-2011 |
20110292821 | Service-Based Inter-Radio Access Technology (INTER-RAT) Handover - In geographical areas with incomplete Time Division Synchronous Code Division Multiple Access (TD-SCDMA) coverage, it may be beneficial for a multimode User Equipment (UE) to handover to a GSM network, a WCDMA network, a CDMA 1x RTT network, or an LTE network. When multiple networks are available to the UE and a poor signal quality is detected in the TD-SCDMA network, one of the available networks may be selected for inter-RAT handover based on a service type of the active call on the UE. For example, when a circuit-switched call, such as a voice call, is in progress on the UE, an inter-RAT handover to a GSM network occurs. In another example, when a packet-switched call, such as a data call, is in progress on the UE, an inter-RAT handover to a WCDMA network occurs. Selecting a network for inter-RAT handover based on an active call service type improves the service provided to the UE. | 12-01-2011 |

The UE registers each of the available call types with a first radio access network. Calls of one of the registered call types may be established, whether UE-originated or UE-terminated, with the first radio access network. When initiating a call of another type, the UE may initiate a different-typed call with another radio access network in the area, while maintaining the call of the first call type with the first radio access network. | 12-01-2011 |
20110292909 | Alternate Transmission Scheme for High Speed Packet Access (HSPA) - Post-hard handover processing in a Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) network may be improved to allow operation of High Speed Packet Access (HSPA) in hard handover. For example, uplink synchronization may be completed concurrent with HSPA to quickly resume HSPA operation in hard handovers. User Equipment (UE) may receive downlink data while completing uplink synchronization. In another example, a unique SYNC_UL code may be assigned to a UE for hard handover. The unique SYNC_UL code allows Node Bs of the TD-SCDMA network to know which UE is performing hard handover. When a Node B is receiving the unique SYNC_UL, the Node B may begin to allocate UL data grants. After receiving UL data from the UE, the Node B may resume High Speed Downlink Packet Access (HSDPA). | 12-01-2011 |

20130142058 | USING TD-SCDMA CONTINUOUS TIME PERIOD TO FACILITATE TD-SCDMA TO GSM WIRELESS HANDOVER - Wireless communication is implemented by a multi-mode user equipment (UE). The method includes selecting a continuous time period during a Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) voice call. The voice call is via a Node B. The selected continuous time period includes multiple subframes. The method also includes preventing the UE from communicating with the Node B during the selected continuous time period, or at least preventing downlink communications with the Node B. The method further includes acquiring a Global System for Mobile communications (GSM) signal from at least one GSM cell during the selected continuous time period. The UE can handover to a selected GSM cell based on the measurements of the acquired GSM cell(s). | 06-06-2013 |
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 |
