摘要： 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.

摘要： Described herein are methods to enable wireless cellular operation in unlicensed and lightly licensed, (collectively referred to as license exempt spectrum. Cognitive methods are used to enable use of unlicensed bands and/or secondary use of lightly licensed bands. Wireless devices may use licensed exempt spectrum as new bands in addition to the existing bands to transmit to a wireless transmit/receive unit (WTRU) in the downlink direction, or to a base station in the uplink direction. The wireless devices may access license exempt spectrum for bandwidth aggregation or relaying using a carrier aggregation framework. In particular, a primary component carrier operating in a licensed spectrum is used for control and connection establishment and a second component carrier operating in a licensed exempt spectrum is used for bandwidth extension.

摘要： 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.
摘要翻译：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。

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 wireless transmit/receive unit (WTRU) (e.g., a millimeter WTRU (mWTRU)) may receive a first control channel using a first antenna pattern. The WTRU may receive a second control channel using a second antenna pattern. The WTRU may demodulate and decode the first control channel. The WTRU may demodulate and decode the second control channel. The WTRU may determine, using at least one of: the decoded first control channel or the second control channel, beam scheduling information associated with the WTRU and whether the WTRU is scheduled for an mmW segment. The WTRU may form a receive beam using the determined beam scheduling information. The WTRU receive the second control channel using the receive beam. The WTRU determine, by demodulating and decoding the second control channel, dynamic per- TTI scheduling information related to a data channel associated with the second control channel.
