    摘要： A fast device discovery protocol with a high success rate for device-to-device (D2D) communication in LTE-A networks is proposed. With the proposed protocol, device discovery is done by monitoring a randomly transmitted beacon from other devices within a pre-defined period. In one embodiment, an eNB receives scheduling requests from D2D UEs and in response allocates a distributed uplink resource for random access of beacon transmission by the D2D UEs. The distributed resource is dynamically allocated based on the number of requesting D2D UEs, a discovery period, and a target discovery probability to minimize the required resource.

    摘要： Methods and apparatus are provided for a UE to send channel status reports (CSR) to a network entity. In one novel aspect, the CSR is generated at the MAC layer. In one embodiment, the UE detects one or more triggering event, obtains a value of channel status from the PHY layer, generates the CSR based on the value obtained from the PHY layer and transmits the channel status report to an eNB. In another embodiment, the UE starts a timer and waits for a UL grant to transmit the CSR. If no UL grant is received before the timer expires, the UE triggers either a dedicated SR or a random access SR. In another novel aspect, the channel status report is generated in a NAS message and sent to a NAS entity through the NAS layer. In one embodiment, the tracking-area-update procedure is used for the CSR.

    摘要： Apparatus and methods are provided to reorder PDCP SDUs. In one novel aspect, a timer-based PDCP reordering process is triggered upon detecting a PDCP gap existing condition, which indicates an SN gap between the PDCP SDUs of two parallel RLC entities larger than zero. The PDCP gap-closing condition is detected when the last-delivered SDU COUNT number plus one equals to the next-expected SDU COUNT number. In one embodiment, all the stored PDCP SDUs with consecutive COUNT numbers starting from the received SDU COUNT number are delivered upon detecting the PDCP gap-closing condition. In another novel aspect, a reordering timer is started upon detecting the PDCP gap condition. In one embodiment, the expiration of the reordering timer triggers the delivery of SDUs to upper layers. In one embodiment, the UE is configured with dual connectivity and the reordering SDU COUNT numbers and the reordering timers are associated with different connectivity configured.
