摘要： Methods of enabling multiuser superposition transmission (MUST) in LTE systems are proposed. MUST operation allows simultaneous transmission for multiple co-channel users on the same time-frequency resources. A higher-layer signaling is used for configuring a UE to enable MUST. When a UE is configured by higher layer to enable MUST, the UE will monitor physical-layer control signaling carrying scheduling information and MUST-related information. Depending on whether MUST exists in each subframe, the UE derives the power allocation between the UE and its co-channel UE on allocated resource blocks. The UE also derives the power allocation based on whether it is configured for CRS-based transmission mode or DMRS-based transmission mode.

摘要： Methods are described herein for adjusting characteristics of signals used to verify or track the reliability of communication between a remote sensor and a managing device. For example, an exchange rate of signals sent between the remote sensor and managing device may be adjusted to minimize power consumption when the devices are determined to be reliably communicating. In some embodiments, apparatuses and methods herein may further be configured to inform an individual of when a remote sensor approaches a physical boundary, moves out of a communication range, is turned off, becomes damaged, or otherwise has or may become incapable of proper or reliable communication.

摘要： Disclosed are methods, wireless network nodes and terminal devices for matching an uplink coverage area and a downlink coverage area. The method may include determine an uplink coverage margin and a downlink coverage margin, calculate an uplink-downlink coverage gap based on differences of the uplink coverage margins and the downlink coverage margins, determine whether the uplink coverage area and the downlink coverage area are matched with each other, and adjust at least one of the uplink coverage area and the downlink coverage area in response to a mismatch of the uplink coverage area and the downlink coverage area. With the proposed methods, wireless network nodes and terminal devices, the uplink and downlink coverage areas could be matched, thereby diminishing the communication overhead and decreasing the delay.

摘要： A radio terminal is provided that can provide a flexible transmission power control for an SRS without restrictions due to the transmission power control of a PUSCH, for the purpose of enabling use of an SRS for various purposes in a HetNet CoMP environment. The radio terminal receives a control signal including a transmission power control command (TPC command) to be applied to an aperiodic sounding reference signal (A-SRS), through a physical downlink control channel (PDCCH), updates a transmission power value of the A-SRS using the TPC command, and transmits the A-SRS using the updated transmission power value in accordance with a transmission request included in a control signal indicating assignment of a physical downlink data channel (PDSCH) or assignment of a physical uplink data channel (PUSCH).

摘要： In order to set optimal wireless parameters, a wireless base station includes: a wireless parameter control unit (402) configured to determine whether it is necessary to perform wireless parameter optimization in an own wireless base station; and a determination unit (404) configured to determine whether another wireless base station performs wireless parameter optimization in the another wireless base station when the wireless parameter control unit determines that it is necessary to perform the wireless parameter optimization. The wireless parameter control unit (402) performs wireless parameter optimization in the own wireless base station when the determination unit determines that the another wireless base station does not perform wireless parameter optimization in the another wireless base station. The wireless parameter control unit cancels to perform wireless parameter optimization in the own wireless base station when the determination unit determines that the another wireless base station performs wireless parameter optimization in the another wireless base station.

摘要： Embodiments disclosed herein relate to methods and systems for grouping pilot signals and using such grouping for pilot strength reporting and set management in multi-carrier communication systems. In one embodiment, an access network may assign a group identifier (or 'group ID') to each of the pilot signals associated with the sector, e.g., based on the coverage areas of the pilot signals, and transmit the pilot signals with the corresponding group IDs. PN offset may be used as the group ID. An access terminal may group the pilot signals received into one or more pilot groups in accordance with their group IDs, and select a representative pilot signals from each pilot group for pilot strength reporting. The access terminal may also use the pilot grouping to perform effective set management.
