Abstract: A method and apparatus for WTRU cooperation are disclosed. An evolved Node B (eNB) may transmit information to a terminal WTRU (T-WTRU) and/or a helper WTRU (H-WTRU). The H-WTRU may re-transmit the information to the T-WTRU. The eNB may re-transmit the information to the T-WTRU. The eNB may send scheduling and control information to the T-WTRU. The transmissions may be performed during a first hop or a second hop. A T-WTRU may receive data from the eNB on a first Physical Downlink Shared Channel (PDSCH) and from the H-WTRU on a second PDSCH. Similar techniques may be used in the uplink direction. Resources may be partitioned by time and/or frequency. The traditional radio link (TRL) between the eNB and the T-WTRU may be in the same band as the crosslink (XL) between the H-WTRU and the T-WTRU or the TRL may be in a different band than the XL.

Abstract: A method and apparatus for neighbor discovery in a wireless communication system are disclosed. A neighbor seeking wireless transmit/receive unit (WTRU) may send a first beacon based on configuration information provided by the network. The neighbor WTRUs receive the first beacon and may send either a report to the network or send a second beacon to the neighbor seeking WTRU. The network may then provide neighbor WTRU information to the neighbor seeking WTRU. The neighbor discovery may be performed within a pre-defined group of WTRUs that is formed based on proximity to the WTRU and/or an attribute of the WTRU. The neighbor discovery procedure may be performed to find neighbor WTRUs in case where a WTRU fails to find any network. A neighbor list may be generated by the neighbor seeking WTRU by measuring reference signals transmitted by neighbor WTRUs on an uplink to the network.

Abstract: A method and apparatus for establishing peer-to-peer communication and performing forwarding under the control of a cellular network are described. A seeking wireless transmit/receive unit (WTRU) may receive a timing signal from at least one discoverable WTRU controlled by a base station. The seeking WTRU may estimate the quality of a radio link (i.e., path loss) between the seeking WTRU and the discoverable WTRU, and determine, (e.g., based on a threshold established by the base station), whether or not to report the estimated radio link quality to a base station that controls the discoverable WTRU. The power of the timing signal may be ramped up in predetermined steps such that the transmission power at any given time is known and may be used by the seeking WTRU for estimating the radio link quality. The timing signal may include at least one of a primary preamble or a secondary preamble.

Abstract: A wireless communication network and method are described for enhancing cell-edge performance of a wireless transmit/receive unit (WTRU). The WTRU may establish a connection with a plurality of sites via respective downlinks (DLs). Each DL may include at least one DL component carrier (CC) that operates on a frequency that is the same or different than one or more of the other CCs. The sites may manipulate their transmit power for a particular CC operating frequency such that the distance from a particular one of the sites to its cell boundary may become larger by increasing its transmit power on the particular frequency, and the distance from at least one of the other sites to its respective cell boundary may become smaller by decreasing its transmit power on the particular frequency. Thus, a coverage overlap between different CC frequencies may be created while maintaining a frequency reuse pattern of one.

Abstract translation: 描述了一种用于增强无线发射/接收单元（WTRU）的小区边缘性能的无线通信网络和方法。 WTRU可以经由相应的下行链路（DL）建立与多个站点的连接。 每个DL可以包括在与其他CC中的一个或多个相同或不同的频率上操作的至少一个DL分量载波（CC）。 站点可以操纵其针对特定CC工作频率的其发射功率，使得通过增加其在特定频率上的发射功率，从特定的站点到其小区边界的距离可能变大，并且距离 通过减小其在特定频率上的发射功率，其各个小区边界的其他站点可能变小。 因此，可以在维持一个频率重用模式的同时创建不同CC频率之间的覆盖重叠。

Abstract: Data traffic may be mapped such that it may be routed via a component carrier. The data traffic may be mapped based on QoS, traffic offload, or the like. This may provide the ability to map certain data to specific component carriers. For example, this may provide a user subscription model with the ability to map one or more services to license exempt (LE) carriers, but not to other carriers. As another example, a user downloading a high definition movie may not want this to be counted towards his or her monthly quota on a licensed carriers or may want to pay flat rate to access supplementary carriers for such services. Allowing data to be mapped such that it may be routed via a component carrier via a component carrier may allow the user to map the data for the high definition movie to a LE carrier.

Abstract: Disclosed herein is HARQ management, scheduling, and measurements, among other things, for cooperative communication. For example, methods herein may be used in situations wherein relaying or helping mechanisms may comprise the use of a relay node which is part of a fixed infrastructure or a relay node which may be a mobile wireless transmit/receive unit (WTRU). In said situations, a first transmission with first data is established between an evolved NodeB (eNB) and a WTRU. A second transmission with second data is established between a relay node (RN) and the WTRU. Said first and second data are combined for decoding. A single HARQ feedback for said first and second transmissions is sent from the WTRU to the eNB.

Abstract: A method and apparatus for combined medium access control (MAC) and radio link control (RLC) processing are disclosed. For uplink processing, a combined MAC/RLC (CMR) entity generates an SDU descriptor and allocates protocol data unit (PDU) descriptor resources. A protocol engine (PE) populates a PDU descriptor for each PDU carrying at least a portion of the SDU and generates a MAC PDU in a physical layer shared memory based on the SDU descriptor and the PDU descriptor. The MAC PDU is generated while moving RLC SDU data from the bulk memory to the physical layer shared memory. For downlink processing, received MAC PDUs are stored in the physical layer shared memory. The PE reads MAC and RLC headers in the MAC PDU and populates an SDU segment descriptor (SD) and corresponding PDU descriptors for each SDU segment. The CMR entity merges SDU SDs that comprise a same RLC SDU.
