    摘要： Systems and methods related to partial interlace frequency domain resource allocations for uplink transmissions from a wireless device are disclosed. In some embodiments, a method performed by a wireless device comprises receiving a resource allocation for an uplink transmission that allocates resources in one or more partially allocated interlaces and performing an uplink transmission on the allocated resources in the one or more partially allocated interlaces in accordance with the resource allocation. In this manner, a low-complexity approach to support flexible frequency domain resource allocation is provided. In addition, using this approach, an interlace may be shared by two or more wireless devices, which may increase spectral efficiency and reduce latency.

    摘要： Embodiments include methods for a user equipment (UE) configured to operate in a radio access network (RAN). Such methods include receiving, from a radio node in the RAN, a new feedback indicator (NFI) that indicates whether acknowledgement signaling previously scheduled for transmission by the UE was received by the radio node. The acknowledgement signaling is associated with one or more first downlink (DL) hybrid ARQ (HARQ) processes. Such methods include, when the NFI indicates the acknowledgement signaling was not received by the RAN node, selecting a first HARQ codebook to be used for encoding the acknowledgement signaling together with further acknowledgement signaling associated with one or more second DL HARQ processes. Such methods include, using the selected first HARQ codebook, encoding the acknowledgement signaling and the further acknowledgement signaling to obtain first encoded information and transmitting the first encoded information to the radio node via an uplink (UL) channel.

    摘要： Embodiments include methods implemented in a wireless device for reporting of a cell global identifier (CGI) in a wireless network. In one embodiment, a method comprises receiving a synchronization signal/physical broadcast channel (SS/PBCH) block from a network node; locating a control resource set (CORESET) configured by the network node through determining a frequency position of the CORESET based on a value received from the network node through radio resource control signaling; and determining and reporting the CGI to the network node based on the located CORESET. In another embodiment, the CORESET is located through testing a set of one or more reference frequency candidates from which a frequency position of the CORESET is determined.

    摘要： There is disclosed a method of operating a receiving radio node in a wireless communication network. The method includes receiving first signaling and second signaling, wherein the first signaling includes first Phase Tracking Reference Signaling, PT-RS, on a first set of subcarriers, and the second signaling includes second PT-RS on a second set of subcarriers, wherein the first set of subcarriers is non-overlapping with the second set of subcarriers, wherein receiving the first signaling is based on estimating a phase noise for the first signaling based on the first PT-RS and the second PT-RS. The disclosure also pertains to related devices and methods.
