  • Patent number: 9860722
    Abstract: An Internet Protocol (IP) router provides location information for an emergency communication session. The IP router receives a base station identifier associated with a request for the emergency communication session. The IP router selects a Public Safety Answering Point (PSAP) based on the base station identifier. The IP router determines a PSAP type and a network type for the selected PSAP. The IP router transfers a location request for delivery to a location control system and receives location information transferred from the location control system. The IP router converts the location information into PSAP signaling used by the selected PSAP based on the PSAP and network type. The IP router transfers the converted location information for delivery to the selected PSAP.

  • Patent number: 9801091
    Abstract: The present invention discloses schemes to perform load control taking uplink BLER statistics into account. An uplink load control method and apparatus are provided in a wireless communication system. The uplink load control method comprises estimating uplink load budget in a cell of the wireless communication system; determining whether the cell is over-loaded based on Block Error Rate (BLER) statistics of non-Guarded Bit Rate (non-GBR) users in the cell and/or Fast Congestion Control (FCC) action statistics in the cell; decreasing the uplink load budget if it is determined that the cell is over-loaded; and increasing the uplink load budget if it is determined that the cell is not over-loaded. Preferably, increasing or decreasing of the uplink load budget is based on the BLER stastics BLERstatistic of targeted users by FCC.

  • Patent number: 9787384
    Abstract: A method for transmitting channel status information in a wireless communication system. A user equipment (UE) transmits first channel information indicating a set of precoding matrices to a base station (BS) periodically, and transmits second channel information indicating one precoding matrix included in the set of precoding matrices to the BS periodically. The second channel information transmitted in a specific subframe is determined based on first channel information that has most recently been transmitted before the specific subframe. Additionally, the UE calculates a channel quality indicator (CQI) transmitted in the specific subframe based on one precoding matrix specified by the first channel information that has most recently been transmitted before the specific subframe and by the second channel information determined based on the first channel information that has most recently been transmitted before the specific subframe.

  • Patent number: 9787514
    Abstract: The present invention relates to a method and an apparatus for transmitting and receiving a reference signal in a wireless communication system. In the method, in order to dynamically switch an uplink (UL) Demodulation-Reference Signal (DM-RS) according to the communication environment, such as CoMP and MU-MIMO, a parameter set for generation of a reference signal sequence is configured to include a Virtual Cell Identifier (VCID) parameter configured by information of a total of 9 bits and a cyclic shift hopping initial value parameter cinitCSH, which is 9-bit information representing one integer value among 510 integer values. Therefore, it may be possible to achieve dynamic transmission or reception of a reference signal and channel estimation through the dynamic transmission or reception of the reference signal even when the communication environment dynamically changes as in a Cooperative Multiple Point transmission and reception (CoMP) scenario.
