摘要： There is provided mechanisms for precoding matrix indicator (PMI) reporting for a set of ports. A method is performed by a wireless device. The method comprises receiving reference signals, the reference signals having been transmitted from a set of ports of a network node. The method comprises determining PMI information for the received reference signals. The method comprises transmitting the PMI information in a report to the network node, wherein the report comprises a combination of identifications of ports from the set of ports and identifications of the reference signals such that an identification of each port is paired with a respective identification of at most one of the reference signals.

摘要： A method of a network node of a wireless communication system is disclosed, wherein the wireless communication system is adapted to operate in accordance with a first (system standard) latency requirement comprising a first latency. The method comprises receiving a message from a wireless communication device, the message indicating that the wireless communication device is adapted to transmit data associated with a second latency requirement comprising a second latency which is lower than the first latency. The method also comprises selecting a configuration for the wireless communication device from a plurality of configurations, wherein each configuration is associated with a respective group of wireless communication devices adapted to transmit data associated with the second latency requirement. Each of the plurality of configurations comprises a respective radio resource for potential transmission by the wireless communication devices of the respective group, and the selection is based on a probability of interference between the potential transmissions by the wireless communication devices of the group associated with the selected configuration. The method also comprises transmitting configuration information to the wireless communication device regarding the radio resource of the selected configuration. Corresponding computer program product, arrangement and network node are also disclosed.

摘要： The present disclosure relates to a method used in a User Equipment (UE) for reporting Hybrid Automatic Repeat Request (HARQ) acknowledgement (ACK)/non-acknowledgement (NACK) for Physical Downlink Shared Channels (PDSCHs) in dynamic time division duplex (TDD) configurations. In the method, a plurality of PDSCHs are received in DownLink (DL) subframes associated with an UpLink (UL) subframe and indicated by a DL reference TDD configuration. The DL subframes are divided into a first subset of DL subframes and a second subset of DL subframes. The first subset of DL subframes is also indicated by an UL reference TDD configuration. A first set of Physical Uplink Control Channel (PUCCH) resource indices are assigned based on resources used in transmission of Physical Downlink Control Channels (PDCCHs) corresponding to the PDSCHs received in the DL subframes of the first subset of DL subframes. A second set of PUCCH resource indices are assigned based on resources used in transmission of PDCCHs corresponding to the PDSCHs received in the DL subframes of the second subset of DL subframes. For each of the received PDSCHs, HARQ ACK/NACK is reported by using PUCCH resources in an order of the assigned first set of PUCCH resource indices for PDSCHs received in the DL subframes of the first subset of DL subframes and in an order of the assigned second set of PUCCH resource indices for PDSCHs received in the DL subframes of the second subset of DL subframes. The present disclosure also relates to a UE and BS for respectively reporting and receiving HARQ ACK/NACK for PDSCHs in TDD configurations.

摘要： One embodiment of the present disclosure relates to a method for random access in a UE in an out-of sync status. The method comprises: sending to a base station a first message including a random access preamble according to a TDD configuration in a SIB; receiving from the base station a second message including a random access response using the random access preamble according to the TDD configuration in the SIB. Another embodiment of the present invention also relates to corresponding method for random access in a base station. According to an aspect of the present disclosure, there are provided corresponding devices.
