Abstract: In a communications apparatus first radio module communicates with a first wireless network and provides wireless communication services in compliance with a first RAT. A second radio module communicates with a second wireless network and provides wireless communication services in compliance with a second RAT. At least two antennas are shared by the first radio module and the second radio module. When the first radio module operates in an idle mode and when the timing of the first radio module performing a first receiving activity coincides with the timing of the second radio module performing a second receiving activity, the second radio module uses the antennas to perform the second receiving activity when a DRX cycle duration of the first radio module in the idle mode is shorter than a DRX cycle duration of the second radio module.

Abstract: A user equipment (UE) receives and decodes a first erroneous transport block (TB) from a base station in a mobile communication network. The UE allocates a first soft buffer having a first buffer size. The first soft buffer is associated with a first HARQ process for storing the first TB. The UE then receives and decodes a second erroneous TB from the base station. The UE allocates a second soft buffer having a second buffer size. The second soft buffer is associated with a second HARQ process for storing the second TB. The UE releases a portion of the first soft buffer to be allocated as part of the second soft buffer. The dynamic buffer allocation method reduces mismatch between rate matching and soft buffer storing when the total number of HARQ processes is small. In addition, more HARQ processes can be supported when the corresponding TB size is small.

Abstract: A method and apparatus for transmitter assisted Quality of Service (QoS) measurement. Time information is generated by the transmitter and transmitted along with a data transmission. A receiving device determines a QoS measurement based upon the time information and the received data. The time information indicates when the data was made available for transmission, which data transmission blocks belong to a single data transmission, and when a transmitter buffer was emptied. The QOS measurements are performance measurement such as, latency measurements and throughput measurements. The time information indicates a time reference relative to the timing of a wireless interface. The time reference is a System Frame Number (SFN), a Connection Frame Number (CFN), a relative count of frame numbers, a count of sub-frames, or a count of Time Transmission Intervals (TTIs). An aggregated QOS measurement is generated based upon the QOS measurement.

Abstract: A method of supporting group communication over LTE MBMS is provided. A UE first establishes a unicast Evolved Packet Service (EPS) bearer in an LTE network for group communication. The UE belongs to a communication group having a communication group ID. The UE receives access information from the network for monitoring downlink (DL) multicast traffic of the DL group communication based on a multicast decision. The UE is then ready for monitoring a multicast Multimedia Broadcast Multicast Service (MBMS) bearer for receiving the DL multicast traffic. The multicast MBMS bearer is associated with a Temporary Mobile Group Identifier (TMGI), and wherein the TMGI is associated with the communication group ID. In one embodiment, the access information comprises mapping information between the TMGI and the communication group ID.

Abstract: Various methods for wireless communication in a device with co-existed/co-located radios are provided. Multiple communication radio transceivers are co-existed/co-located in a user equipment (UE) having in-device coexistence (IDC) capability, which may result in IDC interference. For example, the UE is equipped with both LTE radio and some ISM band applications such as WiFi and Bluetooth modules. In a first method, the network identifies IDC capability by UE identification (e.g., UE ID). In a second method, the UE intentionally performs cell selection or reselection to cells in non-ISM frequency bands. In a third method, the UE signals the existence of ISM band applications via capability negotiation. In a fourth method, the UE signals the activation of ISM band applications by signaling messages (e.g., RRC message or MAC CE). Under the various methods, the UE and its serving eNB can apply FDM or TDM solutions to mitigate the IDC interference.

Abstract: A method of maximum output power configuration with UE preference in carrier aggregation is provided. A UE configures multiple component carriers (CCs) with carrier aggregation for communicating with a serving base station in a mobile communication network. The UE determines channel condition of multiple serving cells over the corresponding multiple CCs. The UE then determines maximum output power for each CC based at least in part on the corresponding channel condition of each CC. Finally, the UE transmits power headroom report (PHR) for each CC to the serving base station, wherein the PHR is calculated based on the determined maximum output power. As a result, the reported PH information is channel condition dependent, which can be used by eNB for facilitating better transmission scheduling.

Abstract: A method of throughput and data volume measurement for minimization of drive test (MDT) is proposed. A base station establishes a radio resource control (RRC) connection with a user equipment (UE) in a mobile communication network. The base station or UE measures transmitted or received data volume during a transmission time of a data burst between the base station and the UE. When the data burst spans multiple measurement periods and the data burst is split at each measurement period boundary. For each measurement period, data volume during the measurement period is measured to generate a measurement result. When throughput measurement is performed by the network, the base station receives location information that is available during the transmission time of the data burst. The data volume measurement is logged with time stamp such that each measurement result can correlated with the location information.

Abstract: A method of providing Local IP Access (LIPA) indication is proposed. In one novel aspect, an enhanced cell selection method is proposed using LIPA capability information. Based on LIPA capability related information, a UE is able to prioritize LIPA-capable cells and establish a corresponding packet data network (PDN) connection accordingly. In one embodiment, LIPA information is informed to the UE via Non Access Stratum (NAS) signaling. The UE stores LIPA capability information when receiving a NAS message from a mobility management entity (MME). Later on, when the UE performs cell selection or reselection in idle mode, the UE can use the stored LIPA capability information to prioritize LIPA-capable cells.

Abstract: Methods for enhanced heterogeneous network mobility are proposed. In a first novel aspect, the cell size of a target cell is considered when determining the TTT value. In one embodiment, pico-specific Time-to-Trigger (TTT) value is configured. When the target cell to be measured is a picocell, pico-specific TTT value is applied. In a second novel aspect, precise mobility state estimation (MSE) is achieved by considering the effect of cell size. In one embodiment, when counting cell changes, a cell change to/from a small cell would be counted to lesser extent than a cell change between large cells. UE uses effective parameters for measurement evaluation, by applying better speed state estimation with speed scaling and by applying parameter differentiation that can be dependent on cell size.
