  • Search Space Monitoring
    Publication number: 20240267833
    Abstract: There are provided mechanisms for monitoring search spaces. A first method performed by a wireless device comprises receiving an Orthogonal Frequency-Division Multiplexing (OFDM) symbol in a downlink slot. At least part of the OFDM symbol is included in a device-specific search space and in a common search space. The first method comprises monitoring the device-specific search space for at least one device-specific reference signal (RS) and monitoring the common search space for at least one non-device-specific RS. In a second method, a radio access network node transmits an OFDM symbol included in a device-specific search space and in a common search space. The device-specific search space contains a device-specific RS, or the non-device specific search space contains a non-device-specific RS, or both of these apply.

  • Method and apparatus for identifying and using radio resources in a wireless communication network
    Patent number: 12058699
    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.
