  • Patent number: 11627439
    Abstract: An apparatus and method are provided for receiving data by a first transceiver. The method includes receiving information for at least one transmission mode through higher layer signaling from a second transceiver; and receiving data on a first sub-frame based on a first demodulation reference signal (DMRS), if the at least one transmission mode is transmission mode 9 or transmission mode 10 and the first sub-frame is a multimedia broadcast multicast service single frequency network (MBSFN) sub-frame.

  • Patent number: 11317434
    Abstract: A determination is made whether each predetermined bit of a plurality of predetermined bits of a Semi-Persistent Scheduling (SPS) scheduling assignment for a user equipment (UE) has a respective predetermined value required to validate the SPS scheduling assignment. In circumstances where each predetermined bit of the plurality of predetermined bits of a Semi-Persistent Scheduling (SPS) scheduling assignment is determined to have a respective predetermined value required to validate the SPS scheduling assignment, an action corresponding to SPS is performed. In circumstances where at least one predetermined bit of the plurality of predetermined bits of an SPS scheduling assignment is determined to fail to have a respective predetermined value required to validate the SPS scheduling assignment, the SPS scheduling assignment is discarded and the action is not performed.

  • Patent number: 11147119
    Abstract: Methods for operating a Base Station (BS) and a User Equipment (UE) in a wireless communication system using a primary frequency and one or more secondary frequencies, and apparatuses for the BS and UE for carry out the methods, are provided. The method for operating the BS includes determining whether to activate or deactivate at least one of the one or more secondary frequencies, and transmitting a message comprising a bitmap indicating the activation or deactivation of the at least one of the one or more secondary frequencies to the UE. The method for operating the UE includes receiving a message comprising a bitmap indicating activation or deactivation of at least one of the one or more secondary frequencies from the BS, and activating or deactivating the at least one of the one or more secondary frequencies based on the received message.

  • Patent number: 10687350
    Abstract: A method and apparatus for receiving a Scheduling Assignment (SA) by a User Equipment (UE) in a communication system in which a base station transmits the SA including at least one Information Element (IE) are described. The method includes receiving the SA; identifying if a first IE included in the received SA is set with a first predetermined value and at least one bit in a second IE included in the received SA is set with a second predetermined value; and performing an action corresponding to a semi-persistent scheduling, if the first IE included in the received SA is set with the first predetermined value and the at least one bit in the second IE included in the received SA is set with the second predetermined value.
