    摘要: A method of power headroom reporting (PHR) is proposed. A UE is configured with a plurality of component carriers (CCs) and is served by one or more power amplifiers (PAs) in a wireless system with carrier aggregation. The UE determines transmit power limitation (TPL) information that comprises a set of TPL values, each TPL value corresponds to a UE-configured maximum transmit power for UE-level, PA-level, and CC-level. The TPL information is then reduced to non-redundant TPL values. Based on the non-redundant TPL values, the UE determines power headroom (PH) information that comprises a set of PH values. Each PH value equals to a TPL value subtracted by a UE-calculated transmit power. The UE reports the PH information to a base station via a fixed-length or variable-length MAC CE at each PHR reporting instance.

    摘要: A method of obtaining system frame number for handover is provided. A UE receives a handover command from a serving base station in a serving cell. The UE performs downlink synchronization with a target base station. Upon synchronization, the UE determines a radio frame boundary of a target cell. The UE then obtains a system frame number of the target cell based on the radio frame boundary. The UE performs a handover procedure with the target cell by transmitting a RACH preamble to the target base station. The RACH preamble is transmitted over a PRACH resource determined from the system frame number without reading SFN information from a PBCH/BCH broadcasted from the target base station. Finally, the UE establishes data connection with the target base station. Handover interruption time is reduced by obtaining SFN before PBCH reading and decoding.

    摘要: A network-based positioning mechanism is proposed. A serving BS first allocates radio resource to a target UE for network-based positioning in a wireless communication system. The target UE then transmits a positioning reference signal (PRS) to the serving BS and a plurality of cooperative BSs at the same time instant. All the cooperative BSs then conduct PRS detection and TOA measurements. Finally, the serving BS conducts positioning estimation based on the TOA measurement results. In one novel aspect, only one PRS transmission is required in one positioning opportunity for one positioning result. Candidates of PRS are selected with respect to different scenarios and allocated in a PRS resource region. Multiple positioning opportunities and multiple reference signals may be multiplexed over time, frequency or code domain in the PRS resource region. In one embodiment, the PRS is configured in such a way that both radio resource consumption and interference is minimized.
