摘要:
A method and an apparatus are provided for initializing token buckets to a non-zero value, preserving the token buckets during a medium access control (MAC) reset or handover, resetting the token buckets based on a minimum bucket size or ratio of sizes, and transmitting a token status report.

Providing discontinuous reception (DRX) is disclosed. In DRX mode a wireless transmit/receive unit (WTRU) may periodically wake up, in relation to a DRX interval, to check for a paging message. The WTRU may reenter the DRX mode if there is no paging message. The WTRU may receive another specified DRX interval, in connection with a broadcast message, based on the activity of the WTRU. The another DRX interval may be increased as inactivity of the WTRU increases.

A method and apparatus are disclosed for prioritizing logical channels when a new transmission is performed. Logical channel resources are allocated for available data to a plurality of logical channels. A maximum bit rate (MBR) credit (i.e., token) is decremented in a buffer (i.e., bucket) associated with a particular one of the logical channels by the size of a medium access control (MAC) service data unit (SDU). The MBR credit may have a negative value. If any of the allocated channel resources remain, the logical channels are served n a decreasing priority order until the data is exhausted. A radio link control (RLC) SDU is not segmented if the whole RLC SDU fits into the remaining resources. The MAC SDU excludes a MAC PDU header and MAC padding.

摘要:
A method and apparatus for logical channel prioritization in a wireless transmit receive unit (WTRU), including the WTRU receiving multiple streams of a multiple input/multiple output (MIMO) signal, a physical layer (PHY) of the WTRU providing an indicator for each of the multiple streams to a medium access control (MAC) layer of the WTRU, and the MAC layer performing logical channel multiplexing based on the indicator for each of the multiple streams.

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.

A method and apparatus for handling interactions between measurement gap, automated repeat request, discontinuous reception and discontinuous transmission in wireless communications are disclosed. The method and apparatus are for real-time data and non-real time data in both an uplink and a downlink.
摘要:
The present invention is a method and apparatus for resource allocation signaling for grouping user real time services. Uplink signaling for voice activity reporting of each user's transition between an active state and an inactive voice state is sent from a wireless transmit/receive unit to a Node B. Radio resource allocation to users of a wireless communication system varies based on user measurement reporting, a pre-determined pattern such as frequency hopping, or a pseudorandom function. Grouping methods are adjusted to better utilize the voice activity factor, so that statistical multiplexing can be used to more efficiently utilize physical resources.

摘要:
Discontinuous reception (DRX) operations for wireless communications implementing carrier aggregation are disclosed. Physical downlink control channel implementation for carrier aggregation is also disclosed. DRX methods are disclosed including a common DRX protocol that may be applied across all component carriers, an individual/independent DRX protocol that is applied on each component carrier, and hybrid approaches that are applied across affected component carriers. Methods for addressing the effects of loss of synchronization on DRX, impact of scheduling request on DRX, uplink power control during DRX, and DRX operation in measurement gaps are disclosed.
