摘要： A method performed by a wireless device of configuring uplink sounding transmissions is provided. The method includes receiving, from a network node, receiving, from a network node, different sets of configuration parameters for sounding signal transmissions for the wireless device. Each of the different sets of configuration parameters includes a time-domain parameter and different frequency allocations. The method further includes receiving, from the network node, downlink control information, DCI, comprising information that indicates which of the configured frequency allocations that should be applied for the SRS transmission. Furthermore, the method includes generating a sounding reference signal based on the received DCI.

摘要： A method for random access performed by a terminal device comprises determining an association between random access resource and shared channel resource for a request message for a random access procedure, based at least on whether a frequency hopping is enabled for the shared channel resource, or when a frequency hopping is enabled for the shared channel resource; and transmitting, to a network node, the request message according to the association. An association between random access resource and shared channel resource of signaling transmissions in a random access procedure can be configured flexibly and efficiently.

摘要： According to some embodiments, a method is performed by a user equipment for reporting channel state information. The user equipment is configured with two or more channel state information reference signal, CSI-RS, resources in a CSI-RS resource set. The method comprises: selecting at least two CSI-RS resources from the CSI-RS resource set, wherein each of the at least two selected CSI-RS resources are associated to a set of spatially multiplexed layers, wherein different sets comprise different layers; determining a preferred precoder matrix for the selected CSI-RS resources; and transmitting a CSI report indicating the selected CSI-RS resources and the preferred precoder matrices. The method may further comprise calculating a channel estimate for the selected CSI-RS resources, and determining a channel quality indicator, CQI, corresponding to a hypothetical transmission from a plurality of effective channels where layers transmitted through the effective channels mutually interfere. The CSI report may indicate the determined CQI for the selected CSI-RS resources.

摘要： According to some embodiments, a method for use in a network node of transmitting channel state information reference signals (CSI-RS) comprises transmitting a number M of CSI-RS ports to one or more wireless devices. A fraction of the M ports are transmitted over a first physical resource block (PRB) and a remaining fraction of the M ports are transmitted over a second PRB. Some embodiments further comprise mapping the number M of CSI-RS ports to resource elements of a radio subframe. A fraction of the M ports are mapped to a first PRB of the subframe and a remaining fraction of the M ports are mapped to a second PRB of the subframe.
