Abstract: A method for grouping of CS (and comb values) for DM-RS and SRS on shared time-frequency resources is described. The method includes dividing a RS space into at least a first region and a second region. The method also includes allocating, from the first region, a DM-RS sequence CS and/or a DM-RS comb for a DM-RS; and allocating, from the second region, a SRS sequence CS and/or a SRS comb for a SRS. The DM-RS and the SRS are on the same resources on an uplink shared channel (such as a PUSCH for example). The RS space comprises at least one of a CS set and a IFDM comb set. The CS set and/or the IFDM comb set of the first region is based at least in part on a number of physical resource blocks allocated to the uplink shared channel. Apparatus and computer readable media are also described.

Abstract: Solutions for determining a resource for transmitting/detecting an uplink (UL) control signal are proposed. For example, a method includes receiving a physical resource configuration and/or an assigned resource indicator for transmitting the UL control signal, wherein the physical resource configuration indicates a plurality of resources in frequency domain. The method also includes determining a resource based on the received physical resource configuration and/or the assigned resource indicator; and adjusting the determined resource for transmitting the UL control signal based on at least one of an outcome of downlink (DL) listen before talk (LBT) performed prior to the transmission of the UL control signal, an outcome of UL LBT performed prior to the transmission of the UL control signal, and a time gap between the UL LBT and the transmission of the UL control signal.

Abstract: A method may include, by an apparatus, sensing at least one beam; initiating a channel occupancy time based on the sensing; transmitting at least one first downlink transmission on the at least one beam during the channel occupancy time, wherein the at least one first downlink transmission on the at least one beam triggers at least one first uplink transmission on the at least one beam during the channel occupancy time; receiving the at least one first uplink transmission on the at least one beam during the channel occupancy time; determining interference condition on the at least one beam based on the at least one first uplink transmission; and scheduling at least one second downlink transmission or at least one second uplink transmission on the at least one beam with restriction during a rest of the channel occupancy time when the interference condition meets at least one threshold requirement.

Abstract: Methods include performing, by a terminal device, downlink control channel monitoring according to a first time pattern. The methods include determining that data has been transmitted on downlink on a number of symbols and based on the determination that the data is transmitted, suspending the performing of downlink control channel monitoring according to the first time pattern. The methods also include performing downlink control channel monitoring on at least one symbol after transmission of the data.

Abstract: Described are methods for dealing with phase noise, e.g., common phase error and/or inter-carrier interference, in communication systems, and apparatuses for the same. A method can include at least: transmitting one or more reference signals (in-band signals within a channel); and mapping the reference signals to radio resources in the channel for transmission of the reference signals. An amount of the radio resources may depend on, e.g., information about a modulation and coding scheme used for transmission. An associated method can include at least: receiving one or more reference signals, and mapping the reference signals to radio resources in the channel for reception of the reference signals; receiving information about a modulation and coding scheme to be used, an amount of the radio resources depending on, e.g., information about the modulation and coding scheme used for reception; and using the reference signals to compensate for phase noise.
