摘要:
A method for radio resource control (RRC) messaging. The messaging includes transmitting a RRC message upon partial completion of message transmission. The RRC message further comprises an information element (IE) that represents a failed or partially failed condition.
摘要:
The present invention is related to a method and apparatus for facilitating lossless handover in a wireless communication system comprising at least one wireless transmit/receive unit (WTRU), a source evolved Node B (eNB), a target eNB, and a mobility management entity/user plane entity (MME/UPE) where the WTRU is in wireless communication with the source eNB. The source eNB determines to handover the WTRU to the target eNB, requests status reports from the WTRU, and requests handover to the target eNB. The handover request includes context information relating to the WTRU which is sent to the target eNB. The target eNB configures resources for the WTRU and transmits a handover response signal to the source eNB. The source eNB commands the WTRU to perform a handover to the target eNB and forwards data to the target eNB. The WTRU performs the handover to the target eNB.

A wireless communication device is configured as an in-home node-B (H(e)NB). The H(e)NB is configured to perform a locking function to control modification of carrier and user controlled parameters, and also configured to detect a change in location.
摘要:
Method and apparatus for providing inbound mobility to closed subscriber group (CSG) and hybrid cells are described. A wireless transmit/receive unit (WTRU) reads the cell global identity (CGI) of a neighbor cell and reports it to a network of CSG cells. The network maps the CSG cell's physical cell identity (PCI) to the CSG CGI and, if required, requests the WTRU to read the CGI at handover.
摘要:
A method and apparatus are described which perform bandwidth aggregation by simultaneously monitoring and processing a number of simultaneous, non-contiguous or contiguous component carriers in the downlink. A wireless transmit/receive unit (WTRU) can be configured by an evolved Node-B (eNodeB) to support additional component carriers. A pre-configured additional component carrier may be used. Various methods for activating and deactivating the additional component carrier are also described.

摘要:
Methods are presented wherein a WTRU may determine, based on measurements, that it is a victim of interference from another cell such a closed subscriber group (CSG) cell. In addition, methods are presented for the UE to inform the CSG cell that UE is present and is a victim UE. Methods for informing the CSG cell may include the grant of temporary membership to a victim UE, the use of a connected WTRU as a relay, and/or indicating victim status in a control message. The indication may trigger an interference management procedure. Methods for the WTRU to stop interference management at the CSG cell, methods to allow the use of a training period by the CSG eNB to allow for non-CSG WTRUs to report their presence, and methods to indicate how to perform UE Victim Indication are also presented.
摘要:
A method and apparatus for implementing data security and automatic repeat request (ARQ) in a wireless communication system are disclosed. Cipher entities are included in a wireless transmit/receive unit (WTRU) and an access gateway (aGW), and outer ARQ, (or radio link control (RLC)), entities are included in the WTRU and an evolved Node-B (eNode-B). Each cipher entity is located on top of an outer ARQ entity. The cipher entities cipher and decipher a data block by using a generic sequence number (SN) assigned to the data block. The outer ARQ entities may segment the ciphered data block to multiple packet data units (PDUs), may concatenate multiple ciphered data blocks to a PDU, or may generate one PDU from one data block. The outer ARQ entities may segment or re-segment the PDU when a transmission failure occurs.
