Abstract: A user apparatus in a mobile communication system that includes a first and second base station that perform communication with the user apparatus by inter-base station carrier aggregation. The user apparatus includes a setting information reception unit that receives, from the first base station, first setting information for instructing whether to report uplink transmission power information to the first base station, and second setting information for instructing whether to report uplink transmission power information to the second base station. A report control unit reports uplink transmission power information to the first or second base station when detecting a report trigger for performing reporting of the uplink transmission power information. When the report control unit detects a report trigger for a specific base station for which it is instructed not to perform reporting of the uplink transmission power information, the uplink transmission power information is reported to another base station.

Abstract: A method for increasing coverage in a wireless communication system is described. The method comprises, at the network element: transmitting a first portion of subframes comprising a number of resource blocks to a first wireless communication unit in a first mode of operation, wherein the number of resource blocks are transmitted at a first power level per resource block; and transmitting, a second portion of subframes to a second wireless communication unit in a second mode of operation at a second power level, wherein the second portion of subframes comprise a lower number of resource blocks than the first portion of subframes and the lower number of resource blocks is transmitted at a second power level per resource block that is higher than the first power level per resource block.

Abstract: A wireless network allocates uplink resources to wireless communication devices (WCDs) based on power headroom reports, with more resources being allocated to WCDs reporting greater power headrooms. Each WCD may determine a respective power headroom as a difference between its maximum transmit power and a transmit power requirement for its current uplink resource allocation. However, a WCD may report an adjusted power headroom that is obtained, for example, by decreasing its respective power headroom by an adjustment value. The WCD may then receive an uplink resource allocation that is based on the adjusted power headroom that it reported. The adjustment value could be based on a priority level of the WCD, a priority level of data to be transmitted by the WCD, and/or an instruction from the wireless network. In one example, basic-priority WCDs report adjusted power headrooms so that more uplink resources are available for high-priority WCDs.

Abstract: A transport block size (TBS) of a first uplink message (RACH Msg3) transmitted on a Physical Uplink Shared Channel (PUSCH) during a random access procedure in a User Equipment (UE) accessing a radio access network may be determined by receiving a pathloss threshold parameter. A downlink pathloss value indicative of radio link conditions between the UE and a base station (eNB) serving the UE is then determined. A smaller value of TBS is selected from a set of TBS values if the determined pathloss value is greater than an operating power level of the UE minus the pathloss threshold parameter. A larger value of TBS is selected if the pathloss value is less than the operating power level of the UE minus the pathloss threshold parameter and the TBS required to transmit the RACH Msg3 exceeds the smaller TBS value.
