Abstract: Methods and apparatus are described for transmitting and receiving data by a wireless transmit/receive unit (WTRU) over the control plane. The methods may receive data without the use of an Internet Protocol (IP) address. In an example method, a WTRU may enter an evolved packet system (EPS) mobility management (EMM)-registered control plane only (CPO) state after receiving an attach accepted message for CPO operation, and enter an EMM-deregistered state after receiving a detach message, a tracking area update (TAU) reject message or an attach reject message. In another method, a WTRU may switch between operational modes that use an IP address and a user plane to transmit and receive data, and the CPO mode.

Abstract: A method, an apparatus, and a computer-readable medium for wireless communication are provided. The apparatus may be a UE. The UE receives MBMS in an MBMS session from a base station. The UE determines a data receipt metric associated with data received during the MBMS subframes in the MBMS session.

Abstract: Methods, apparatuses, and systems for data transmission are described. A sending terminal sends data and a data identification of the data to a server. The data identification is broadcasted to one or more receiving terminals through a short distance wireless communication. The receiving terminal obtains the data from the server according to the data identification. When the sending terminal needs to transmit data to multiple receiving terminals, the techniques of the present disclosure do not require the sending terminal to establish a point-to-point connection with each of the receiving terminal. Thus, the techniques of the present disclosure effectively reduce transmission time with multiple receiving terminals, improve data transmission efficiency, and lower power consumption at the sending terminal.

Abstract: A method and apparatus for segmenting medium access control (MAC) service data units (SDUs) creates enhanced MAC-es PDUs in the enhanced MAC-e/es sub-layer by concatenating MAC SDUs received from the logical channels. An enhanced transport format combination (E-TFC) selection entity controls the concatenation of MAC SDUs into enhanced MAC-es PDUs. When a MAC SDU is received that is too large to fit into a selected enhanced MAC-es PDU payload, a segmentation entity segments the MAC SDU such that the MAC SDU segment fills the remaining payload available in the selected enhanced MAC-es PDU. The enhanced MAC-es PDU is then assigned a transmission sequence number (TSN) and multiplexed with other enhanced MAC-es PDUs to create a single enhanced MAC-e PDU that is transmitted on the E-DCH in the next transmission time interval (TTI). A HARQ entity stores and, if necessary retransmits the enhanced MAC-e PDU when a transmission error occurs.

Abstract: A system and method for establishing windows that govern the exchange of acknowledgements in a full-duplex communication. The window is established for two nodes which transmit asymmetric frame sizes in full-duplex mode. The window is related to the size of the asymmetric frames. Frames are exchanged in full-duplex between the two nodes, and the window size is defined as enabling the nodes to send data until the number of unacknowledged frames at the nodes is less than or equal to the window size, at which point acknowledgments are exchanged simultaneously. In sending the acknowledgment, both nodes can send acknowledgments simultaneously in full-duplex in the same frequency bin.

Abstract: Embodiments of a multi-transceiver wireless communication device and methods for adaptive multi-band communication are generally described herein. In some embodiments, the multi-transceiver wireless communication device is configurable for half-duplex operation and for asymmetrical full-duplex operation on two non-interfering channels.

A primary transceiver and an auxiliary transceiver may be configured for asymmetrical full-duplex operation when access to both the primary channel and the auxiliary channel is granted. One of the transceivers may be configured for half-duplex operation when access to only one of the channels is granted.

Abstract: A controller device can control the time of a slave sub-system in a chain in a base station system. The controller device comprises a slave transceiver for receiving/transmitting from/to a master sub-system, and a synchronization device for synchronizing a clock of the slave transceiver to a clock of the master sub-system based on the received signal received from the master sub-system. The synchronization circuitry comprises a clock input port for receiving an external clock signal from an external clock generator. At a received signal input port the received signal can be received from the master transceiver. A tracking loop couples the received signal input and the second phase input to a control input of a controllable PLL, for providing a negative feedback which controls a phase and/or frequency of the feedback signal to counter the phase and or frequency error between the external clock signal and the received signal.
