20130294327 | CHARGING OVER A USER-DEPLOYED RELAY - Network entities in a wireless network cooperate to account and charge for data communicated over the wireless network. Accounting and charging enable the network entities to properly allocate charges to a second user equipment that communicates through a first user equipment, which acts as a relay in the wireless network. A network entity receives a request from the first user equipment related to a packet data network connection relating to the second user equipment. The network entity establishes or modifies a connection between a gateway and the first user equipment in response to the request. Charges for the data may be allocated to the second user equipment for data communicated with the identifier of the second user equipment. | 11-07-2013 |
20140016537 | ASSOCIATING TERMINAL USER EQUIPMENT WITH USER EQUIPMENT RELAYS - An operational characteristic of a relay is determined. The relay is a user equipment (UE) serving as an eNB. The operational characteristic includes one or more of a quality of a relay backhaul and a capacity of the relay backhaul. The relay backhaul includes a communications link between the relay and an eNB. A determination of whether to perform a handover of a UE is made based on the operational characteristic of the relay and a corresponding operational characteristic of the eNB. | 01-16-2014 |

According to certain aspects, a wireless node (e.g., a low power node) may receive, from a base station of a first cell, signaling indicating a random access channel (RACH) configuration for a wireless device. The wireless node may then detect the wireless node performing a RACH detection (based on the RACH configuration) and report the RACH detection and desired UL configuration to the base station of the first cell. The base station of the first cell may then select the wireless node for serving the wireless device for UL operations (e.g., based on the reported RACH detection-and similar reports from other wireless nodes detecting the same RACH procedure). | 05-08-2014 |
