    Abstract: A wireless communication method and device are provided. The wireless communication method includes the steps of determining, by a user equipment (UE), that a length of an radio link control (RLC) service data unit (SDU) or RLC SDU segment is greater than a threshold, determining, by the UE, a type of length indicator which is allocated by a network, and determining, by the UE, to force to map the RLC SDU or RLC SDU segment to the end of an RLC protocol data unit (PDU) if the type of the length indicator is a first type.

    Abstract: A method of uplink shaping and extending UE in RRC Idle Mode is proposed. The UE processes a data packet to be sent to the network. The data packet is associated with a traffic type. If the data packet belongs to a normal traffic type, then the UE enters RRC Connected mode and thereby transmitting the data packet to the network. If the data packet belongs to a background traffic type, then the UE buffers the data packet and the UE is prohibited from entering RRC Connected mode until a triggering condition is satisfied for uplink transmission. The proposed mechanism achieves power saving by reducing the activity of uplink transmission. In addition, the proposed mechanism also reduces signaling overhead to enhance network efficiency.

    Abstract: A method of system information (SI) acquisition with reduced signaling overhead is proposed. To reduce SI broadcast overhead, the quantity of periodic SI broadcast and the frequency of on-demand SI acquisition need to be reduced. To reduce the frequency of on-demand SI acquisition, rather than always re-acquire SI when serving cell changes, UE is enabled to reuse stored SI information elements across different cells. More specifically, a novel concept of SI ID is introduced to be associated with an area that applies the same SI configuration. UE can reuse stored SI information elements if the stored SI information elements are valid based on the SI ID and validity check.

    Abstract: A user equipment (UE) compares a total amount of data available for transmission, including a total amount of packet data convergence protocol (PDCP) data volume and radio link control (RLC) data volume pending for initial transmission in two associated RLC entities comprising a primary RLC entity and a secondary RLC entity, to a threshold. In response to the total amount of data available for transmission being less than the threshold, the UE indicates an amount of the PDCP data volume to a first medium access control (MAC) entity associated with the primary RLC entity as well as indicating zero to a second MAC entity associated with the secondary RLC entity. In response to the total amount of data available for transmission being greater than or equal to the threshold, the UE indicates the amount of the PDCP data to both the first MAC entity and the second MAC entity.

    Abstract: Methods and apparatus are provided for load balancing and load distribution using a set of alternative configurations. In one novel aspect, the UE receives and stores a set of alternative configurations. The UE selects a new alternative configuration upon detecting one or more triggering events and performs a cell selection based on the new alternative configuration. In one embodiment, the UE receives the set of alternative configurations from a broadcast signaling channel. In another embodiment, the UE applies a new configuration upon detecting one or more triggering events. In another embodiment, the UE selects the new alternative configuration using a hash function based on a UE identifier, wherein the hash function hashes to a priority class, and wherein each priority class maps to an alternative configuration. In one embodiment, a prohibition timer is used to prevent too frequent resource changes.

    Abstract: A method and apparatus for transmitter assisted Quality of Service (QoS) measurement. Time information is generated by the transmitter and transmitted along with a data transmission. A receiving device determines a QoS measurement based upon the time information and the received data. The time information indicates when the data was made available for transmission, which data transmission blocks belong to a single data transmission, and when a transmitter buffer was emptied. The QOS measurements are performance measurement such as, latency measurements and throughput measurements. The time information indicates a time reference relative to the timing of a wireless interface. The time reference is a System Frame Number (SFN), a Connection Frame Number (CFN), a relative count of frame numbers, a count of sub-frames, or a count of Time Transmission Intervals (TTIs). An aggregated QOS measurement is generated based upon the QOS measurement.

    Abstract: A method of extended DRX paging includes a base station that transmits extended DRX configuration information and a User Equipment (UE) receives the extended DRX configuration from the base station. The UE determines a first number of frames that are included in a hyper-frame based at least in part on the extended DRX configuration information and selects a hyper-frame number. The hyper-frame number is based at least in part on the extended DRX configuration information. The UE maintains a hyper-frame count and the hyper-frame count is incremented after each hyper-frame. The UE then goes into sleep mode and the UE determines a wake up time before a standard DRX cycle that occurs during the selected hyper-frame. The UE may also determine a first wake up time and a second wake up time based on the selected hyper-frame number and synchronization error between a first cell and a second cell.
