| 发明名称 | Method and apparatus for contention-based uplink data transmission | ||
| 摘要 | A method and apparatus for a wireless transmit receive unit (WTRU) to use a contention-based uplink communications channel, applies a rule-based restriction of access to the contention-based uplink channel that attempts to use at least one contention-free uplink channel allocation for uplink transmissions on a condition that at least one contention-free uplink channel allocation has been granted. | ||

| 主权项 | 1. A method implemented by a wireless transmit receive unit (WTRU) accessing a contention-based (CB) uplink communication channel, the method comprising: deciding whether to send an uplink transmission using the CB uplink communication channel or a contention-free uplink channel allocation based on a rule-based restriction of access to the CB uplink communication channel; restricting access to the CB uplink communication channel on a condition that at least one rule of the rule-based restriction is satisfied; and on a condition that more than one uplink grant is received for a same sub-frame, deciding not to send an uplink transmission on the CB uplink communication channel on a condition that at least one uplink grant is received in a random access response. | ||
