摘要： Systems, methods, and apparatuses for inter-device communication in wireless communication systems are provided. A user equipment (UE) may initiate a direct inter-device communication link between UEs located in proximity. The UEs participating in the inter-device communications may perform a device handshake procedure or a device discovery procedure to set up appropriate transmission parameters for the communication over the inter-device communication link. A device-to-device radio network temporary identification (DD-RNTI) may be used for the inter-device communication link. Long term evolution (LTE) downlink or uplink radio resources may be used for communications over the inter-device communication link.

摘要： Systems, methods, and apparatuses for transmitting physical hybrid automatic repetition request indicator channel (PHICH) signals using adaptive code rates are provided. In accordance with one implementation, various PHICH code rates may be supported by configuring a different number of resource element groups (REGs) to transmit the PHICH signal. The information regarding the REGs may be transmitted to a user equipment (UE) in a radio resource control (RRC) message or in an uplink grant message or in a medium access control (MAC) control element. Correspondingly, the UE may detect the PHICH signal with adaptive code rate on the indicated REGs. Furthermore, channel state information (CSI) may be transmitted from the UE to a base station to indicate the measured PHICH quality, such that the base station may determine appropriate PHICH code rate for the UE based on the CSI information.

摘要： Systems and methods for user equipment (UE) transmit power adjustment for inter-device communication in wireless communication systems are provided. A UE may communicate directly with another UE over a direct inter-device communication link when they are located in proximity. The UE may adjust its transmit power for the inter-device communication during a device handshake/discovery procedure. For example, the UE may adjust its transmit power for the inter-device communication based on a data exchange between the UE and the other UE over the inter-device communication link. Long term evolution (LTE) downlink or uplink radio resources may be used for the data exchange over the inter-device communication link.
