This disclosure relates to the 5th generation (5G) or pre-5G communication system for supporting a higher data rate after the 4th generation (4G) communication system such as Long Term Evolution (LTE). The method for operating the core network in a wireless communication system according to this disclosure comprises the processes of determining the content to store in the terminal based on the location information of the terminal, transmitting the content transmission command to the base station so as to transmit the content to the terminal in response to the determination, checking whether the terminal has entered the overload cell, and forming a D2D communication link between the terminal and another adjacent terminal when it is identified that the terminal has entered the overload cell.

A wireless transmit/receive unit (WTRU) may select a first type of buffer status information or a second type of buffer status information. The first type of buffer status information may indicate an amount of data buffered and the second type of buffer status information has less bits and is a different format than the first type of buffer status information. The WTRU may select, subsequent to a number of subframes of a transmission of buffer status information of a first type, buffer status information of the first type for transmission.

Disclosed is a base station including at least one baseband processing unit, a front-haul network and at least one remote radio unit. The base station further includes an adaptation unit configured to control transmission data packets between the baseband processing unit and at least one remote radio unit. The adaptation unit includes a buffer module and a communication module that is configured to determine if the buffer module includes at least one data packet to be transmitted at a scheduled instant of time, and in response to a detection that the at least one data packet is missing the communication module inserts padding data to the buffer module. The invention also relates to a method thereto.

The present disclosure provides a random access method and a terminal device. The method includes: reserving a first MAC PDU buffered in a HARQ buffer or buffering a second MAC PDU in a HARQ buffer if a random access procedure is successful, where the first MAC PDU is a PDU that is buffered in a Msg3 buffer in a contention random access procedure, the second MAC PDU is a PDU that includes at least data content of the first MAC PDU and is buffered in a target buffer, and the target buffer and the Msg3 buffer are different buffers.

A system and method of operating a content distribution system includes receiving and storing a first content at a first storage device; communicating the first content from the first storage device to a second storage device through a local area network, said second storage device downstream from the first storage device. The method also includes storing the first content in the second storage device; requesting the first content at a first user device, and communicating the first content from the second storage device to a first user device when requested by the first user device. Other embodiments of this aspect include corresponding computer systems, apparatus, and computer programs recorded on one or more computer storage devices, each configured to perform the actions of the methods.

A relay device first receives a data packet from a network device through a first link, and sends the data packet to user equipment through a second link. A protocol stack of the relay device consists of a physical layer, a media access control layer, and a segmentation function or a resegmentation function of a radio link control layer; a protocol stack of the relay device consists of a physical layer, a media access control layer, a segmentation function or a resegmentation function of a radio link control layer, and an adaptation layer; or a protocol stack of the relay device consists of a physical layer and a hybrid automatic repeat request function of a media access control layer. The first link is a wireless communication link between the network device and the relay device, and the second link is a wireless direct communication link between the relay device and the user equipment.
