  • Patent number: 11817947
    Abstract: A modulation technique, such as for example either Pi/2 BPSK or QPSK, is selected for transmission, based on a characteristic of the data to be transmitted, or the physical channel over which it is to be transmitted. The data characteristic may be the coding rate, or characteristics indirectly related to the coding rate, such as the number of coded bits or number of uncoded bits (payload size). The physical channel characteristic may for example be the physical channel bandwidth, the physical channel length, a number of physical channel modulation symbols, a number of the physical channel resource elements used for the data to be transmitted, or a number of the physical channel modulation symbols carrying the data to be transmitted.

  • Publication number: 20230345499
    Abstract: A network node, such as a base station, identifies radio resources within an overall bandwidth using a first resource referencing scheme, while a wireless communication device identifies radio resources within an allocated portion of the overall bandwidth using a second resource referencing scheme. Advantageously, the device correctly identifies given radio resources pointed to by a resource identifier expressed according to the first resource referencing scheme, by translating the resource identifier into the second resource referencing scheme according to mapping information that relates the two schemes. Correspondingly, the network node enables the wireless communication device to perform such translations by providing the mapping information either implicitly or explicitly.

  • Publication number: 20230328752
    Abstract: A method of operating a network node in a wireless communication system includes configuring a downlink control information (DCI) message that schedules uplink or downlink communications with a user equipment (UE) in a plurality of serving cells. The DCI message does not include an explicit new data indicator (NDI) field for at least one of the serving cells scheduled by the DCI message. The network node transmits the DCI message to the UE. A method performed by a UE includes receiving a DCI message that schedules uplink or downlink communications in a plurality of serving cells. The DCI message does not include an explicit NDI field for a serving cell scheduled by the DCI message. In response, the UE determines an NDI value associated with scheduled communications for the serving cell or determines that the scheduled communications for the serving cell contains a new data transmission.
