摘要： A method, network node and wireless device (WD) providing a framework for simultaneous multi-panel uplink (UL) transmission are disclosed. According to one aspect, a method in a network node includes configuring the WD with at least two transmission configuration indicator (TCI) states. The method also includes transmitting downlink control information (DCI) comprising an indication of a first TCI state and a second TCI state to be activated by the WD. The method also includes receiving a first physical uplink shared channel (PUSCH) transmission occasion or a first set of PUSCH layers transmitted using a first spatial filter associated with the first TCI state. The method also includes receiving a second PUSCH transmission occasion or a second set of PUSCH layers transmitted using a second spatial filter associated with the second TCI state.

摘要： There is provided a method, in a wireless device, for transmitting a reference signal. The method comprises: receiving a configuration via Radio Resource Control (RRC) from a network node, the configuration comprising a list of slot offset values configured for a Sounding Reference Signal (SRS) resource set; receiving Downlink Control Information (DCI) triggering the SRS resource set, wherein the DCI contains a slot offset bitfield for indicating one of the slot offset values in the list of slot offset values and wherein each entry of the list of slot offset values corresponds to a codepoint of the slot offset bitfield; and transmitting a reference signal using SRS resources configured in the triggered SRS resource set based on the indicated slot offset value.

摘要： The present invention relates to a first network device (20; 51) for transmission of reference signal resources comprising an antenna arrangement (61) having at least two panel (62, 63) configured to generate beams (53) in different directions. The first network device (20; 51) comprises a control circuitry (210) configured to transmit, as part of performing a beam selection procedure with a second network device (30a; 52), a first reference signal resource in one or more beams from a first of the at least two panel, and a second reference signal resource in one or more beams from a second of the at least two panel. The one or more beams from the first of the two panels is different from the one or more beams from the second of the two panels, and the first reference signal resource is time-wise overlapping with the second reference signal resource when transmitted.

摘要： Embodiments include methods for a user equipment (UE) configured for beam reporting in a wireless network. Such methods include receiving a configuration of at least first and second resource sets. Each resource set includes multiple reference signals associated with corresponding multiple spatial filtering configurations. Such methods include performing measurements on the reference signals of the first and second resource sets and sending, to the wireless network, a beam report including the measurements arranged in at least first and second groups. Each group includes measurements performed on a first reference signal from the first resource set and on a second reference signal from the second resource set. The first and second reference signals are received concurrently by the UE. One measurement included in the first group is expressed as an absolute value, while others in the first group are expressed as differential values relative to the absolute value.

摘要： According to some embodiments, a method performed by a wireless device for indicating preferred uplink beams in a beam sweep report comprises determining a downlink channel quality associated with each downlink reference signal of a plurality of downlink reference signals. Each of the plurality of downlink reference signals is associated with a beam pair between the wireless device and a network node. The method further comprises determining an uplink performance metric associated with each downlink reference signal of the plurality of downlink reference signals and selecting a subset of the plurality of downlink reference signals for reporting in a beam sweep report. At least one downlink reference signal is selected for inclusion in the subset based on its associated uplink performance metric. The method further comprises transmitting a beam sweep report to the network node based on the selected subset of downlink reference signals.

摘要： There is provided mechanisms for adaptive cell-shaping in a cellular network in which a group of radio access network nodes provide network access. A method is performed by a network node. The method comprises obtaining an indication of combined network performance degradation in a region in which a first radio access network node in the group of radio access network nodes provides network access and increased need for network access for prioritized service and/or prioritized subscribers in this region. The method comprises initiating adjustment of cell- shaping parameters of at least one radio access network node in the group of radio access network nodes. Network access for the prioritized service and/or prioritized subscribers in the region is maintained by this at least one radio access network node in the group of radio access network nodes.
