Abstract: A multimode wireless communication terminal that communicates using a first radio access technology (RAT) and a second RAT determines whether the first and second RATs are in an active state, and modifies a maximum transmit power limit of the first RAT based on a voice codec rate of a voice transmission on the second RAT when the first RAT and the second RAT are in the active state concurrently, wherein the second RAT is conducting the voice transmission in the active state. In an alternative embodiment, the limit is modified based on a transmit power status of the second RAT or on a transmission type of the first RAT.

Abstract: Wireless networks share UE location information in order to identify possible inter-network aggressors. If a first network determines, based on the location data it receives from a second network, that one of the first network's UEs may cause excessive interference to one or more of the second network's UEs, the first network grants A-MPR to its UE (e.g., by signaling the UE). The first network's UE can then lower its transmit power in order avoid interfering with the second network's UE.

Abstract: A method and apparatus provide for low latency transmissions. A resource assignment can be received. A first set of time-frequency resources in a subframe can be determined from the resource assignment. A second set of time-frequency resources in the subframe can be determined. The second set of time-frequency resources can be for a low latency data transmission. The second set of time-frequency resources can overlap with at least a portion of the first set of time-frequency resources. A regular latency data transmission in the subframe can be decoded based on the determined first and second set of time-frequency resources. The regular latency transmission can have a longer latency than the low latency transmission.

Abstract: Apparatuses and methods are disclosed for using RF energy on an uplink channel to transition an unpowered access point to a power-up state. One apparatus 300 includes a processor 305 that receives uplink data from a remote unit 105 over a first uplink channel and determines whether to offload the data traffic of the remote unit 105 to an access point 115, wherein the access point 115 transitions to a power-up state after harvesting radio energy from a second uplink channel. The processor 305 further allocates uplink resources to the remote unit 105 on the second uplink channel in response to determining to offload the data traffic of the remote unit 105 to the access point 115. The apparatus may further include a radio transceiver 325 for receiving uplink data from the remote unit 105 over the first and second uplink channels.

Abstract: A first user equipment (UE) and a second UE communicate with a network element (e.g., an eNB) over a carrier (e.g., an uplink or downlink cellular carrier). The first and second UEs also engage in D2D communication using resources of the carrier that have been allocated to them by the network entity. Using the allocated resources, the first and second UEs communicate using a subframe that has a first set of symbols in during which the first UE transmits, a second set of symbols during which the second UE transmits, and a guard interval between the first and second UEs.

In various implementations, if a wireless terminal receives a first set of data and a second set of data simultaneously on different frequencies, then it sends signals responsive to the first and second sets of data on different slots of a single uplink subframe and on different frequencies.

A composite report for the subframe including the first and second PCMAX values is then sent to a base station.
