    Abstract: A method, an apparatus, and a computer-readable medium for wireless communication are provided. The apparatus receives a discovery message through a device-to-device communication channel using a first resource element corresponding to a first time slot and a first frequency resource. The device-to-device communication channel may be a wireless communication channel. Upon reception of the discovery message, the apparatus determines a second resource element corresponding to a second time slot and a second frequency resource based on the first time slot and the first frequency resource in a deterministic resource allocation manner. The apparatus may alter the discovery message for rebroadcast in a deterministic message alteration manner. The apparatus rebroadcasts the discovery message using the second resource element. The discovery message may be rebroadcast through the same device-to-device communication channel in which the discovery message is received.

    Abstract: A method, an apparatus, and a computer program product for congestion control are provided. The apparatus measures respective signal qualities in at least two regions of a resource block, compares the respective signal qualities to each other, and determines a network congestion level based on the comparison. In an aspect, the apparatus may further decide whether to use resources respectively included in the at least two regions based on the network congestion level. Alternatively, the apparatus may further identify at least one MTC device or UE to refrain from using resources respectively included in the at least two regions when the network congestion level is above a threshold, and transmit a congestion control signal to the at least one identified MTC device or identified UE when the network congestion level is above the threshold.

    Abstract: Techniques are described for wireless communication. One method includes estimating a pathloss from each of a plurality of relay candidates to a first communication device to generate a first capacity estimate for the first communication device for each of the plurality of relay candidates; receiving at the first communication device, from a second communication device, a second capacity estimate for the second communication device for each of the plurality of relay candidates; and selecting a relay from the plurality of relay candidates for relaying communications between the first communication device and the second communication device based at least in part on each first capacity estimate for the first communication device and each second capacity estimate for the second communication device.

    Abstract: Various methods and apparatus are directed to collision detection and/or avoidance regarding peer to peer connection identifiers. A wireless communications device broadcasts a signal indicating its acquired connection identifier in one of two alternative blocks. A base station monitors peer to peer signaling in its coverage area and tracks the usage of peer to peer connection identifiers by pairs of devices. The base station detects when multiple pairs of devices are using the same peer to peer connection identifier. The base station provides assistance to the peer to peer network to avoid a collision or facilitate rapid collision detection by the peer to peer devices. In one approach the base station sends an instruction for a connection to switch its connection identifier. In another approach the base station sends a connection a message to bias its selection as to which of the two alternative blocks to use for transmission.

    Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives a configuration indicating multicast broadcast single frequency network (MBSFN) subframes within a radio frame. The configuration indicates a number of symbols of an MBSFN subframe for receiving a wide area network (WAN) control signal and remaining symbols of the MBSFN subframe dedicated for peer-to-peer communication. The apparatus communicates with a peer via the symbols dedicated for peer-to-peer communication. Alternatively, the apparatus receives a configuration indicating a portion at a beginning and/or end of a guard period of a special time division duplex (TDD) subframe. The portion is reserved for an uplink timing advance and/or switching from transmission to reception and/or reception to transmission. The configuration also indicates a remaining portion of the guard period of the special TDD subframe for peer-to-peer communication. The apparatus communicates with a peer via the remaining portion.
