    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: Methods, systems, and devices are described for device-to-device (D2D) wireless communication. A device may transmit an initiation message to a base station indicating that the device desires to initiate a D2D communication session. The device may then receive a response from the base station that includes parameters for configuration of the D2D session. When it has data to send to another device, the device may transmit buffer status report (BSR) to the base station. The base station may respond with a grant of D2D scheduling assignment (SA) configured according to the previously sent parameters. For example, the message may be scrambled with a D2D temporary identity sequence. In some cases, the device may transmit a group identification (ID) code to the base station, and the group ID may be associated with an index, so an SA for that group can be reference by index.

    Abstract: Methods, systems, apparatuses, and devices are described for predicting an automatic gain control setting for long range discovery in a peer-to-peer network. In one configuration, an energy of each resource of a first set of resources may be estimated. A total energy of a second set of resources used for long range discovery in the peer-to-peer network may be predicted. The predicted total energy may be based at least in part on the estimated energy of each resource of the first set of resources. An automatic gain control setting for the second set of resources may be predicted based at least in part on the predicted total energy.

    Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in connection with selection of a communication mode based on traffic type information. In one example, a network entity (e.g., a WiFi router, Picocell, Fentocell, an eNB, etc.) is equipped to obtain traffic type information for content to be transmitted by a network entity, determine a communication mode to use for transmission of the content based on the traffic type information, and transmit the content using the determined communication mode. In an aspect, the traffic type information may indicate that the content is a best effort traffic type, a latency sensitive traffic type, or no traffic type is available.

    Abstract: Methods, systems, and devices for wireless communications are described. A first UE may perform a sensing procedure to identify that a first sidelink resource is available. The first UE may select the first sidelink resource for transmitting a first message and one or more remaining sidelink resources for transmitting one or more additional messages. The first CE may transmit the first message via the first sidelink resource to a second UE, the first message indicating a reservation and a resource utilization probability vector for the remaining sidelink resources. The resource utilization probability vector may include the resource utilization probabilities for each sidelink resource. The second UE may select a first sidelink resource of the remaining sidelink resources or a second sidelink resource for transmitting a sidelink message based on the resource utilization probability vector, and may transmit the sidelink message to the first UE in the selected sidelink resource.
