  • RESOURCE ALLOCATION FOR UPLINK TRANSMISSIONS IN UNLICENSED SPECTRUM
    Publication number: 20220086893
    Abstract: 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.

  • Systems and Methods for Reliable Dynamic Indication for Semi-Persistent CSI-RS
    Publication number: 20220078658
    Abstract: According to certain embodiments, a method in a wireless device is provided that includes receiving, from a network node, dynamic allocation signaling to commence measurement on a semi-persistent CSI-RS resource. A first measurement is performed on the CSI-RS resource. A first CSI report based only on the first measurement is transmitted to the network node. A trigger message is received from the network node that is different from the dynamic allocation signaling. The trigger message triggers semi-persistent CSI reporting, and the wireless device initiates semi-persistent reporting.

  • TRANSMISSION OF CONTROL INFORMATION USING MORE THAN ONE BEAM PAIR LINK
    Publication number: 20220030617
    Abstract: One way to increase robustness against beam pair link failure is by transmitting downlink (DL) control signaling (e.g., PDCCH) in more than one beam. That is, one way to mitigate BPLF is for the UE to receive DL control signaling over both a first BPL (e.g., active BPL) and a second BPL (e.g., monitored BPL) but with larger duty cycle for the second BPL compared to the first BPL. For example, the control signaling can be scheduled every slot on the first BPL and scheduled every Nth slot on the second BPL. In this way, in case the first BPL is blocked and the UE cannot decode the control signaling on the first BPL, the UE can receive control signaling transmitted on the second BPL.

  • SRS hopping pattern based on UE bandwidth configuration
    Patent number: 11228464
    Abstract: Suitable hopping patterns designed to alleviate degradations of SRSs are provided herein. When a UE (12, 14, 200) transmits multiple SRS within the same time resource (e.g., slot), the UE is configured with an SRS hopping pattern (including an SRS bandwidth) based on at least a UE configuration bandwidth. In one exemplary embodiment, a node (12, 14, 200), e.g., a UE (14, 200) or a network node (12, 200) of a wireless network (10), controls the SRS configurations for SRS transmissions by the UE (14, 200) via one or more resource blocks. The SRS configuration comprises a hopping pattern and a first (e.g., hopping) bandwidth associated with the SRS transmissions. The node (12, 14, 200) determines the first bandwidth, and determines a second (e.g., configuration) bandwidth associated with a configuration of the UE (14, 200).
