Abstract: Device-to-device operations are scheduled based on receive and transmit pools that may have a conflict in time domain. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus for resolving time domain conflict in device-to-device communication are provided. The apparatus may compute a first block rate metric for a first device-to-device communication on a first frequency and a second block rate metric for a second device-to-device communication on a second frequency. The apparatus may detect a time-domain conflict between the first device-to-device communication on the first frequency and the second device-to-device communication on the second frequency. The apparatus may prioritize the first device-to-device communication on the first frequency and the second device-to-device communication on the second frequency based on the first block rate metric and the second block rate metric.

Abstract: In device-to-device (D2D) communication in a licensed spectrum, selection of a transmit pool and distribution of codes to be transmitted to the transmit pools for more efficient transmission is desired, for a given period. The apparatus may a user equipment (UE) for D2D communication in a licensed spectrum. The UE sets a discovery epoch to a shortest discovery period among discovery periods of a plurality of transmit resource pools, each transmit resource pool of the plurality of transmit resource pools associated with a respective frequency. The UE estimates a channel utilization of each transmit resource pool of the plurality of transmit resource pools based on one or more previous transmissions on each transmit resource pool of the plurality of transmit resource pools. The UE selects a transmit resource pool among the plurality of transmit resource pools for a D2D transmission within the discovery epoch based on the estimated channel utilizations.

Abstract: The present disclosure enables an eNB to identify and/or profile stationary verses mobile UEs located within its cell. In addition, the eNB may tailor a discovery filter that includes all of the PACs (e.g., advertisements) being transmitted by stationary UEs within a vicinity of the cell. The discovery filter may be shared with a network server such that a mobile UE that requests information associated with a particular PAC will receive a list of all PACs within the vicinity of the mobile UE. The apparatus monitors transmissions from a plurality of UEs over a period of time. The apparatus determines at least one stationary UE in the plurality of UEs based on one or more features associated with the transmissions.
