Abstract: Methods and apparatuses are related to multi-user parallel channel access (MU-PCA). For example, a wireless transmit/receive unit (WTRU) is provided that is one of the plurality of WTRUs operable to simultaneously communicate via a plurality of channels managed by an access point (AP). The WTRU includes a receiver configured to receive, from the AP, over at least one channel of the plurality of channels, a group poll (G-Poll) message that includes a resource allocation that indicates at least one allocated channel of the plurality of channels for the WTRU; and a transmitter configured to transmit an uplink request message, to the AP in response to the G-Poll message, over the at least one allocated channel of the plurality of channels, the uplink request message corresponding to uplink data the WTRU has for transmission to the AP.

Abstract: A concurrent multi-carrier (MC) wireless transmit/receive unit (WTRU) capable of concurrently processing multiple radio carriers may simultaneously connect to multiple base stations for receiving multiple service flows via multiple air links. The concurrent-MC WTRU may be serviced by multiple base stations through multiple concurrent radio carriers simultaneously during normal operation for downlink and/or uplink communications. Each base station may provide special services optimized for each base station. The WTRU may use a lower quality air link for low priority services or low resolution data services while use a higher quality air link for high bandwidth or low latency services. A diversity gain may be achieved by combining signals from multiple base stations. The support and use of the multiple air links at the WTRU may be transparent to the base stations. Alternatively, base stations' support may be provided for setting up and operations of the multiple air links.

Abstract: Method and apparatuses may provide multi-user parallel channel access (MU-PCA). For example, a wireless transmit/receive unit (WTRU) is provided that belongs to a MU-PCA group of a plurality of WTRUs that are configured to simultaneously communicate via a plurality of channels managed by an access point (AP). The WTRU may include a receiver configured to receive a data message, from the AP, over a channel associated with the WTRU of the plurality of channels, wherein the data message is one of a group of multiple data messages transmitted simultaneously by the AP over the plurality of channels; and a transmitter configured to transmit a message to the AP over the channel associated with the WTRU, wherein the message includes an indication bit for notifying the AP whether the WTRU has uplink (UL) data to transmit to the AP.

Abstract: Systems, methods, and instrumentalities are disclosed to desynchronize transmissions in group-based operations. A group user equipment (UE), e.g., a UE that is a member of a group of UEs, may be in an inactive mode. The group UE may receive a multicast message indicating that the group UE may enter an active mode. For example, the group UE may use the active mode for periodic reporting of its monitoring activity to the network. The multicast message may indicate a mechanism for the group UE to use to send an uplink transmission to the network. The group UE may send the uplink transmission to the network at a transmission time indicated by the mechanism. The transmission time may be desynchronized from other UEs in the group.

Abstract: Method and apparatus for reporting feedback information are disclosed. A wireless transmit/receive unit (WTRU) may receive an allocation message which indicates an allocation of downlink resources for a downlink transmission and an allocation of a first uplink control channel. Further, the indicated allocation of the first uplink control channel may indicate a starting symbol for the first uplink control channel and subcarriers for the first uplink control channel. Also, the WTRU may receive the downlink transmission on a downlink carrier in the indicated allocation of downlink resources for the downlink transmission. Moreover, the WTRU may transmit a plurality of uplink control channels carrying hybrid automatic repeat request (HARQ) acknowledgment/negative-acknowledgement (ACK/NACK) information for the downlink transmission and other control information. In addition, the plurality of uplink control channels may include the first uplink control channel.
