Methods and systems for transmitting uplink control information in an LTE Advanced system are disclosed. A user device may determine whether uplink control information and/or available channels meet certain criteria and determine whether the uplink control information should be transmitted on a physical uplink control channel, a physical uplink shared channel, or both, based on the criteria. Criteria may include the size of the uplink control information (absolute size or relative to space available on a channel or a threshold value), the type of control information bits, the number of available (i.e., active or configured) component carriers, and the amount of power that may be required to transmit the uplink control information on more than one channel.

Signaling uplink control information in LTE-A

A method, a wireless transmit/receive unit (WTRU), and a base station are disclosed. The WTRU comprises a receiver, a transmitter, and a processor. The WTRU receives at least one radio resource control (RRC) message indicating an uplink resource for the WTRU and receives grants over first channels associated with the indicated uplink resource. The WTRU transmits uplink data using the indicated uplink resource based on the received grants, and, based on a trigger, deactivates the indicated uplink resource and to stop the reception of grants over the first channels associated with the indicated uplink resource and flush hybrid automatic repeat request (HARQ) buffers associated with the indicated uplink resource. The base station is configured to communicate with the WTRU.

Method and apparatus for receiving and releasing wireless communication resources

A method and apparatus for controlling transmit power in a wireless local area network (WLAN). For example, a station may receive, from an access point (AP), a beacon frame that includes a field indicating a maximum transmission power for at least one of a plurality of operational bandwidth that the AP supports. The station may determine a transmission power for a signal to be transmitted to the AP based on the at least one of the plurality of operational bandwidths indicated in the received beacon. The station may then transmit the signal at the determined transmission power.

Method for transmit and receive power control in mesh systems

A method and a wireless transmit/receive unit (WTRU) are disclosed. The WTRU comprises a receiver, a transmitter, and a processor. The WTRU receives a system information block (SIB) including a parameter indicating a number of transmissions for a random access message and a parameter indicating transmission duration information for the random access message. The WTRU transmits a random access preamble and a random access message, wherein the random access message is transmitted for a duration indicated by the parameter indicating transmission duration information for the random access message. The WTRU retransmits the random access message, wherein the random access message is retransmitted a number of times indicated by the parameter indicating the number of transmissions for the random access message and for the duration indicated by the parameter indicating transmission duration information for the random access message.

Method and apparatus for performing random access transmissions

A method and an apparatus is provided for transmitting uplink data on uplink resources. The method and apparatus includes receiving a radio resource control (RRC) message indicating uplink resources for wireless transmit/receive unit (WTRU) and medium access control (MAC) timer information, transmitting uplink data based on the indicated uplink resources, and deactivating the indicated uplink resources in response to a MAC timer expiring, wherein the MAC timer is configured based on the MAC timer information.

Method and apparatus for transmitting uplink data on uplink resources

A method and apparatus of performing discontinuous reception (DRX) and downlink inter-frequency and inter-radio access technology (RAT) measurements in CELL_FACH state are disclosed. While in DRX mode, a wireless transmit/receive unite (WTRU) may perform inter-frequency and inter-RAT measurements in a measurement occasion that fall into a DRX period. The WTRU may take the measurements on first predetermined number of frame in which a DRX frame would coincide after a last reception frame if DRX operation was ongoing. The WTRU may periodically wake up for downlink reception in CELL_FACH state in accordance with common DRX pattern that is common to all WTRUs in a cell or may wake up from DRX upon reception of the order and receiving a common traffic.

Method and apparatus for performing discontinuous reception and downlink inter-frequency and inter-radio access technology measurements in CELL_FACH state

Representative methods, apparatus and systems to adjust Do Not Disturb (DND) levels in a wireless transmit/receive unit (WTRU) are disclosed. One representative method includes determining, by the WTRU, that a user of the WTRU is participating or is going to participate in a meeting; obtaining, by the WTRU, organizational hierarchy information; determining a priority associated with one or more meeting participants based on the organizational hierarchy information; and adjusting, without user input, a DND level of the WTRU based on the determined priority.

Methods, apparatus and systems for adjusting do-not-disturb (DND) levels based on callers and meeting attendees

Systems, methods, and instrumentalities are disclosed for generating, transmitting, and/or receiving a hybrid spread waveform. The hybrid spread waveform may include a data portion and a hybrid guard interval (HGI) portion. The HGI portion may include a fixed prefix portion or a fixed suffix portion, and an adaptive low power tail (LPT) portion. The fixed prefix portion or the fixed suffix portion is a low power cyclic prefix (LPCP). The LPCP may be generated at least based on at least the channel delay spread and a power regrowth length. The adaptive LPT portion may be generated using a zero tail (ZT). The LPT is generated by inserting zeros at IFFT or DFT processing stage. A part of the adaptive LPT portion is used to carry data or control information. A waveform may be switched between a hybrid spread waveform and a fixed-CP waveform, e.g., via control signaling.

System, method, and apparatus for low power cyclic prefix (CP) based hybrid spread waveforms

A method and apparatus for requesting and releasing resources for a wireless transmit/receive unit (WTRU) and/or Node B. The WTRU may transmit a channel acquisition request to the Node B and receive a resource allocation from the Node B. The resource allocation may include a common resource. The WTRU may release the common resource. The release may be based on one or more conditions. The channel acquisition request or the resource allocation may include information related to one or more channels or resources.

Method and apparatus to reduce radio resource overhead associated with intermittent traffic

A method and an apparatus is provided for terminating an enhanced random access channel (E-RACH) message in an E-RACH transmission. Triggers for terminating the E-RACH message are provided. The actions upon termination of the E-RACH messages are provided to release enhanced dedicated channel (E-DCH) resources while in cell forward access channel (CELL_FACH) state or transition to cell dedicated channel (CELL_DCH) state.

Method and apparatus for terminating transmission of a message in an enhanced random access channel

A method for discontinuous reception (DRX) implemented in a wireless transmit/receive unit (WTRU) during cell reselection including initiating cell reselection; disabling DRX operation, wherein disabling DRX operation enables continuous reception; transmitting a CELL UPDATE message; receiving a CELL UPDATE CONFIRM message; and enabling DRX operation based on the received CELL UPDATE CONFIRM message.

A method and apparatus for transmitting and receiving a packet via high speed downlink packet access (HSDPA) are disclosed. At least one HSDPA medium access control (MAC-hs) service data unit (SDU) is segmented into a plurality of segments. MAC-hs protocol data units (PDUs) are generated from the segments wherein each MAC-hs PDU includes at least one segment. Each MAC-hs PDU may include one segment from a single MAC-hs SDU. The size of the segments may match to the size of the MAC-hs PDUs minus the size of the header of the MAC-hs PDU. The sizes of the segments may be determined based on the number of segments to which the MAC-hs SDU is segmented. Alternatively, each MAC-hs PDU may include a combination of segments from a plurality of MAC-hs SDUs or a combination of at least one segment from one MAC-hs SDU and at least one entire MAC-hs SDU.
