The message indicates an allocated set of uplink resource blocks and the number of separate uplink resource grants represented by the set is known or signaled, such that user terminals recognize that separate subsets of uplink resource blocks within the set each correspond to a separate contention-based uplink grant. Information included in the contention-based uplink grant message, or otherwise signaled can be used to control the probability at which the user terminals attempt contention-based uplink transmissions and/or to control the MCS used for such transmissions. | 07-21-2011 |
20110249632 | Scheduling Retransmissions for Contention-Based Access - A base station supports a contention-based channel and a schedule-based channel. If too many mobile terminals simultaneously transmit on the contention-based channel, the base station schedules retransmissions to those terminals on the schedule-based channel. Supporting this, a terminal transmits a user transmission on the contention-based channel that includes both a data transmission and a reference signal. The terminal derives this reference signal by selecting one of a plurality of cyclic shifts (CSs). Correspondingly, the base station receives the user transmission and can determine the selected CS even if it is unable to demodulate the data transmission. The base station then determines a retransmission identifier (RTI) mapped to that CS, according to a mapping between CSs and RTIs, and sends scheduling information for any needed retransmission to the terminal by addressing that information to the RTI. Meanwhile, the terminal knows this mapping and monitors for scheduling information addressed to that RTI. | 10-13-2011 |
