Abstract: A first allocation of physical resources for uplink transmission is received over a downlink signaling channel. Data of a logical channel is received. A first block is transmitted over the first allocated physical resources in response to receipt of the data of the logical channel. A timer is initiated in response to transmission of the first block. In response to an expiration of the timer and not receiving a second allocation of physical resources, a first type of request from a plurality of types of requests is selected and the selected first type of request for the second allocation of physical resources is transmitted over an uplink signaling channel. The second allocation of physical resources is received in response to the transmitted first type of request. A second block is transmitted in response to the second allocation of physical resources over the second allocated physical resources.

Abstract: A wireless transmit/receive unit (WTRU) may generate, on a condition that a scheduling request and an acknowledgement/negative acknowledgement (ACK/NACK) or channel quality information (CQI) are to be transmitted, a message having the scheduling request and the ACK/NACK or the CQI. The message may be transmitted over a physical uplink control channel. The WTRU may determine whether scheduling request information, including buffer status, is to be transmitted. The scheduling request information may be transmitted as in-band information.

Abstract: A method and apparatus for adjusting a channel quality indicator (CQI) feedback period to increase uplink capacity in a wireless communication system are disclosed. The uplink capacity is increased by reducing the uplink interference caused by CQI transmissions. A wireless transmit/receive unit (WTRU) monitors a status of downlink transmissions to the WTRU and sets the CQI feedback period based on the status of the downlink transmissions to the WTRU. A base station monitors uplink and downlink transmission needs. The base station determines the CQI feedback period of at least one WTRU based on the uplink and downlink transmission needs and sends a command to the WTRU to change the CQI feedback period of the WTRU.

Abstract: A method and apparatus are provided for dynamic resource allocation, scheduling and signaling for variable data real time services (RTS) in long term evolution (LTE) systems. Preferably, changes in data rate for uplink RTS traffic are reported to an evolved Node B (eNB) by a UE using layer 1, 2 or 3 signaling. The eNB dynamically allocates physical resources in response to a change in data rate by adding or removing radio blocks currently assigned to the data flow, and the eNB signals the new resource assignment to the UE. In an alternate embodiment, tables stored at the eNB and the UE describe mappings of RTS data rates to physical resources under certain channel conditions, such that the UE uses the table to locally assign physical resources according to changes in UL data rates. Additionally, a method and apparatus for high level configuration of RTS data flows is also presented.

This includes time/frequency mapping of above-mentioned control signals into resource blocks (RBs) of multimedia broadcast multicast services (MBMS) single frequency network (MBSFN)-reserved sub-frames in the RN cell and encoding procedures for these.

Abstract: A combined open loop and closed loop (channel quality indicator (CQI)-based) transmit power control (TPC) scheme with interference mitigation for a long term evolution (LTE) wireless transmit/receive unit (WTRU) is disclosed. The transmit power of the WTRU is derived based on a target signal-to-interference noise ratio (SINR) and a pathloss value. The pathloss value pertains to the downlink signal from a serving evolved Node-B (eNodeB) and includes shadowing. An interference and noise value of the serving eNodeB is included in the transmit power derivation, along with an offset constant value to adjust for downlink (DL) reference signal power and actual transmit power. A weighting factor is also used based on the availability of CQI feedback.

Abstract: A method and wireless transmit/receive unit (WTRU) for uplink transmission are disclosed. A WTRU receives configuration information. The configuration information includes logical channel priority information and a maximum number of hybrid automatic repeat request (HARQ) transmissions. For a transmission time interval (TTI), the WTRU identifies a HARQ process to use for uplink transmission for the TTI on a condition that an uplink grant is for the TTI. The WTRU selects data for uplink transmission for the TTI. For a new uplink transmission, data is allocated in decreasing order of priority based on the logical channel priority information. The WTRU initializes a transmission counter. The transmission counter indicates a number of transmissions associated with the selected data. The WTRU transmits the selected data over an uplink channel based on the uplink grant using the identified HARQ process.
