摘要： Method and apparatus are disclosed for optimizing Random Access Channel (RACH) transmissions from wireless transmit/receive units (WTRUs) for multiple transmissions. A WTRU may initiate uplink transmission for a random access procedure using a configured time resource such that the uplink resources may be time shared by a plurality of WTRUs. The transmission time may be calculated on an absolute or relative basis. A backoff time may be applied before starting the uplink transmission. The backoff time may be WTRU-specific, WTRU group-specific, specified per access class and may be determined based on a priority basis. A scaling factor may be applied to the backoff time. A contention free allocation method may be used to determine the appropriate resource. The data may be transmitted with and without a preamble. The WTRUs may include machine type communication devices and may be grouped in accordance with a number of factors or characteristics.

摘要： Methods and apparatus are provided for performing group-based machine-to-machine (M2M) communication. Machine-type communication (MTC) wireless transmit/receive units (WTRUs) may operate in M2M groups. A group of MTC WTRUs may be paged collectively as a group. An MTC WTRU may store an individual international mobile subscriber identity (IMSI) associated with the MTC WTRU, and a group-based IMSI associated with the MTC group that the MTC WTRU belongs to. The MTC WTRU may use one or both IMSIs to receive paging messages. When the MTC WTRU receives a paging message, the MTC WTRU may compare a recipient IMSI contained in the paging message to the individual IMSI and the group- based IMSI. If the recipient IMSI matches the individual IMSI and the group-based IMSI, the MTC WTRU may proceed to process the paging message.

摘要： Systems and methods are provided for receiving data from multiple cells. A wireless transmit and receive unit (WTRU) may receive data from cells in a multi-point set that includes a primary serving cell and one or more assisting serving cells. The WTRU measures the quality of cells in the multipoint set as well as neighboring cells. Based on the cell quality, the WTRU triggers a reporting event, such cell adding event, cell removal event, or cell replacement event, and sends a measurement report to the network. The WTRU receives an indication of a change to the multi-point set from the network, and modifies the multi-point set accordingly.

摘要： Mobility states are defined in order to prevent excess signaling overhead and to conserve power on a wireless transmit/receive unit (WTRU) in a wireless network. The WTRU may determine that is operating in a low mobility state based on triggers related to the frequency of movement of the WTRU between network cells. The WTRU may change cells less frequently in a low or no mobility state than in a normal mobility state. Upon determining that the WTRU is in the low or no mobility state, the WTRU may configure mobility procedures associated with the low or no mobility state in order to conserve power and other network resources. The WTRU may coordinate its mobility state with the network.

摘要： Maintaining time alignment with multiple carriers is contemplated. A group of uplink carriers (UL CC sets) that operate with a single Timing Advance (TA) may be determined, and a TA value may be applied to a specific UL CC set. A wireless transmit/receive unit's (WTRU) capability of using multiple TAs may define a group index of a few bits for each UL CC set. A TA Command received in a Random Access Response message may be used to apply the TA value to each UL carrier of the UL CC set. The WTRU may determine which UL CC set the TA value applies to based on which DL carrier the command was transmitted from. The WTRU may determine which UL CC set the TA value applies to based on the Group Index being explicitly provided in the command. The WTRU may release multi-CC configurations upon Time Alignment Timer (TAT) expiry.
摘要翻译：考虑与多个载体维持时间对准。可以确定以单个定时提前（TA）操作的一组上行链路载波（UL CC集），并且可以将TA值应用于特定的UL CC集合。使用多个TA的无线发射/接收单元（WTRU）能力可以为每个UL CC集合定义几比特的组索引。可以使用在随机接入响应消息中接收的TA命令将TA值应用于UL CC集合的每个UL载波。 WTRU可以基于从哪个DL载波发送命令来确定哪个UL CC设置TA值适用于哪个DL载波。基于在命令中明确提供的组索引，WTRU可以确定应用TA值的哪个UL CC设置。当时间对准定时器（TAT）到期时，WTRU可以释放多CC配置。

摘要： Enhanced protocols and devices may be used to alleviate loss of spectrum efficiency in wideband transmission. The protocols may implement a wideband transmission opportunity (TXOP) truncation where one or more of the channels involved in communication over the wideband are released. In one scenario, a wireless transmit/receive unit (WTRU) may obtain a TXOP for a 2 MHz bandwidth mode frame transmission with another device capable of operating in a 2 MHz bandwidth mode and a 1 MHz bandwidth mode. The WTRU may conduct a request-to- send (RTS)/clear-to-send (CTS) frame exchange in the second bandwidth mode, and truncate the TXOP by transmitting a contention free (CF)-End frame in the first and second bandwidth modes. In another scenario, an AP may obtain a TXOP for a 2 MHz bandwidth mode frame transmission with a WTRU capable of both 2 MHz and 1 MHz bandwidth modes.
