Abstract: Disclosed herein are methods and systems for uplink control feedback design in relation to the high speed dedicated physical control channel (HS-DPCCH). First uplink data may be transmitted on a HS-DPCCH to a first serving cell and a second serving cell, where the first serving cell may be used as a timing reference cell for the uplink transmission. The first serving cell may be associated with a first NodeB and the second serving cell may be associated with a second NodeB. First downlink data may be received from the first serving cell and second downlink data may be received from the second serving cell. A timing reference for uplink transmission may be changed such that the second serving cell may be used as the timing reference cell. Second uplink data may be transmitted on the HS-DPCCH using the second serving cell as the timing reference cell.

Abstract: Method and apparatus are disclosed for determining a physical uplink power level for transmissions on a physical uplink channel. In one embodiment, a random access channel (RACH) uplink message is transmitted. The RACH uplink message includes a RACH message power level and/or a downlink pathloss figure. A downlink message including a power offset value is received. The physical uplink power level is set for transmissions on the physical uplink channel based on the power offset value. In another embodiment, a RACH uplink message is transmitted and a downlink message including a relative power offset value is received. The physical uplink power level for transmissions on the physical uplink channel is then set based on the relative power off set value.

Abstract: Methods and apparatuses are described herein for rediscovery and medium access for wake-up radios. For example, a wireless transmit receive unit (WTRU) may receive, via a first transceiver, a frame that includes a wake-up radio (WUR) operation element having a first counter value. The WTRU may deactivate the first transceiver and activate a second transceiver, wherein the first transceiver enters into a doze state and the second transceiver is in an awake state. The WTRU may then receive, via the second transceiver in the awake state, a WUR frame that includes a second counter value indicating an update of a plurality of basic server set (BSS) parameters associated with the first transceiver. On a condition that the second counter value is different than the first counter value, the WTRU may activate the first transceiver to update the plurality of BSS parameters, wherein the first transceiver enters into an awake state.

Abstract: A method performed by a station (STA) for operating in a wireless local area network (WLAN) is provided. The method includes communicating, in an operation mode, with devices in the WLAN including another STA and transmitting, to the another STA, one or more of a data frame or a management frame including a medium access control (MAC) header. The MAC header includes an operation mode field indicating a change in one or more parameters of the operation mode. The method includes transmitting or receiving, based on a determination that the indicated change in the one or more parameters of the operation mode has taken effect, a frame to or from the another STA in accordance with the indicated change in the one or more parameters of the operation mode.

Abstract: A wireless transmit/receive unit (WTRU) communicating in a wireless local area network (WLAN) system may use efficient acknowledgement (ACK) setup and transmission procedures in conjunction with other transmission and power saving techniques, such as target wake time/restricted access window (TWT/RAW), power save multi-poll (PSMP) and/or transmission opportunity (TXOP) mechanisms. In an example, a WTRU may transmit a frame including an indication that a TWT/RAW (or TXOP) period is scheduled, an indication that multi-WTRU acknowledgement (ACK)/block ACK (BA) will be used for acknowledgement, and/or targeted transmission time(s) for the transmission of multi-WTRU ACK/BA frame(s). The WTRU may trigger the start of the TWT/RAW period, and may receive at least one data frame from another WTRU(s). The WTRU may transmit multi-WTRU ACK/BA frame(s) during the targeted transmission time(s) to acknowledge the at least one data frame received from the other WTRU(s).
