20130016601 | APPARATUS AND METHOD FOR MAINTAINING A CIRCUIT-SWITCHED VOICE CALL IN A MULTI-RAB WIRELESS COMMUNICATION SYSTEM IN AN AREA OF WEAK COVERAGE - An apparatus and a method are provided for improving user experience in a multi-radio access bearer (multi-RAB) wireless communication system. After a user equipment establishes a circuit-switched communication link and a packet-switched communication link with a core network, it may receive an indication of an error associated with the packet-switched communication link. Here, if the value of a timer such as the RAB re-establishment timer T314 has a predetermined value (e.g., 0), the user equipment may release the packet-switched communication link, and maintain the circuit-switched communication link. The packet-switched communication link may then be re-established. In this fashion, errors that may occur on the data call need not interrupt a voice call. | 01-17-2013 |
20140022989 | METHOD AND APPARATUS FOR DYNAMICALLY CONFIGURING A CELL UPDATE MESSAGE - The present disclosure presents a method and apparatus for dynamically configuring a cell update message at a user equipment (UE). For example, the method may include determining that a size of the cell update message at the UE is above a threshold value after a “measured results on random access channel (RACH)” information element (IE) is excluded from the cell update message. Furthermore, such an example method may include removing one or more IEs from the cell update message until the size of the cell update message is at or below the threshold value. As such, dynamic configuration of a cell update message at a UE is achieved. | 01-23-2014 |
20140036798 | METHOD AND APPARATUS FOR ENHANCING DATA RETRANSMISSION TO IMPROVE CALL PERFORMANCE - A method and apparatus for enhancing data retransmission to improve call performance are described. At least one protocol data unit (PDU) may be transmitted from a transmitting entity to a receiving entity. The at least one PDU may be part of a service data unit (SDU). It may be determined to perform a communication re-establishment. As such, the SDU may be retransmitted, beginning with a first PDU transmitted as part of the SDU. In an aspect, the transmitting entity may be a radio link control (RLC) transmitting device and the receiving entity may be an RLC receiving device in communication with one another across a network. In another aspect, the transmitting entity may be a radio link control (RLC) transmitting protocol layer and the receiving entity may be a radio link control (RLC) receiving protocol layer both within a protocol stack of a device. | 02-06-2014 |
20140254505 | PRIORITIZING TIME CRITICAL DATA FOR TRANSMISSION DURING POWER LIMITED STATE IN DC-HSUPA OPERATION - Techniques for prioritizing time critical data for transmission during a power-limited state in DC-HSUPA operation are described. A user equipment (UE) may be in a power-limited state. The UE may identify non-scheduled, time critical data and scheduled data as available for transmission. The UE may detect that a minimum transport block size is about to be selected for a transmission on a secondary uplink carrier. The UE may prioritize the non-scheduled, time critical data over the scheduled data and transmit the non-scheduled, time critical data on a primary uplink carrier based on the prioritizing. The UE also may transmit the scheduled data during a transmission time interval (TTI) that is different from the TTI during which the non-scheduled, time critical data was transmitted. The non-scheduled, time critical data and the scheduled data may be transmitted using transmit diversity. | 09-11-2014 |
20140293887 | METHOD AND APPARATUS FOR A SMART RANDOM ACCESS PROCEDURE IN A TELECOMMUNICATION NETWORK - Aspects of the present disclosure provide for a method and an apparatus for wireless communications using an intelligent Random Access Channel (RACH) procedure that may increase the probability of obtaining an available E-DCH resource quickly in a Universal Mobile Telecommunication System. | 10-02-2014 |
20140362699 | METHODS AND APPARATUS FOR IMPROVING CALL PERFORMANCE AND DATA THROUGHPUT - Methods and apparatus are described for improving call performance and data throughput. The methods and apparatus include receiving one or more packet data units (PDUs) during a transmission time interval (TTI) from a network entity, wherein the one or more PDUs are associated with a radio bearer. Further, the methods and apparatus include determining one or more out-of-order PDUs from the one or more PDUs. Moreover, the methods and apparatus include reordering the one or more out-of-order PDUs, wherein the one or more out-of-order PDUs are reordered within the TTI. Additionally, the methods and apparatus include processing the one or more reordered PDUs. | 12-11-2014 |
20150036518 | APPARATUS AND METHODS FOR CONTINUOUS INTER-FREQUENCY MEASUREMENT RECONFIGURATIONS OF DC-HSUPA UE - Disclosed are systems and methods for continuous inter-frequency measurement reconfigurations in a DC-HSUPA User Equipment (UE). In one aspect, the system may configure the UE to perform intra-frequency measurements on a frequency f1 and inter-frequency measurements on a frequency f2 in a dual carrier (DC) downlink (DL) mode and a single carrier (SC) uplink (UL) mode. The system may then reconfigure the UE to operate in a DC UL mode and continuing to perform inter-frequency measurements on the frequency f2 in the DC UL mode. The system may then reconfigure the UE to operate in the SC UL mode and continuing to perform inter-frequency measurements on frequency f2 in the SC UL mode. | 02-05-2015 |
20150043441 | ENHANCEMENTS FOR TRANSMISSION OVER MULTIPLE CARRIERS - Data is selectively transmitted over one or more carriers of a set of carriers. According to some aspects of the disclosure, a decision may be made to forgo the transmission of a preamble via one of the carriers (e.g., channels). For example, in a multi-carrier system, transmission of a preamble via one carrier may be inhibited if all of the data can be transmitted via another carrier. According to some aspects of the disclosure, a decision may be made to transmit different types of data on a single carrier rather than on multiple carriers. For example, a single carrier may be used to transmit schedule data and non-scheduled data if all of the data can be transmitted on one of the carriers (e.g., during a single transmission time interval). In this case, transmission of a preamble on another one of the carriers may therefore be inhibited. | 02-12-2015 |
