摘要： 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.
摘要翻译：可以映射数据业务，使得其可以经由分量载波路由。可以基于QoS，流量卸载等来映射数据业务。这可以提供将某些数据映射到特定组件载体的能力。例如，这可以提供具有将一个或多个服务映射到许可证豁免（LE）运营商而不是其他运营商的能力的用户订阅模型。作为另一个例子，用户下载高清晰度电影可能不希望这被计入他/她的授权运营商的每月配额，或者可能想要支付统一费率来访问这样的服务的辅助运营商。允许数据被映射以便经由分量载波经由分量载波被路由可以允许用户将高清晰度电影的数据映射到LE载波。

摘要： 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.

摘要： 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.

摘要： A method and apparatus are described for maintaining communications over a bearer when at least one of two wireless transmit/receive units (WTRUs) transitions to idle mode. In one case, a direct WTRU-to-WTRU bearer may be released in response to a first one of the WTRUs transitioning to idle mode. A second one of the WTRUs may send a first of a plurality of packets to the first WTRU via a default packet data network (PDN) connection or a default bearer towards the PDN connection. The first packet may have a destination Internet protocol (IP) address of the second WTRU and trigger paging to the first WTRU. The first WTRU may transition to connected mode in response to the paging. Other cases may release a portion of a bearer, rather than the entire bearer. A method and apparatus for initiating proximity service bearer establishment is also described.
