摘要： Embodiments include methods, performed by a user equipment (UE), for receiving reference signals (RS) in a wireless network. Such methods include receiving, from a network node in the wireless network, a configuration for connected-state RS transmitted by the network node. In some embodiments, the connected-state RS can be periodic channel state information RS (CSI- RS) or periodic tracking RS (TRS). Such methods include, while the UE is in a non-connected state and based on the received configuration, determining that the connected-state RS are available during one or more first occasions. Such methods include, while the UE is in the non- connected state, selectively receiving the connected-state RS during the first occasions. Other embodiments include complementary methods performed by a network node, as well as UEs and network nodes configured to perform such methods.

摘要： Method for a User Entity, UE, being adapted to transmit uplink data according to a NR TDD scheme, with a NR bases station, gNB, the UE being further adapted to transmit HARQ-ACK information, being an ACK or a NACK for received data on a downlink channel and a Scheduling Request, SR, may be provided comprising an indication of data or no data to be pending for transmittal on the up-link. The method comprises - establishing if HARQ-ACK info is available in a slot (203), - establishing if an SR-PUCCH is present in the slot (204), - if no SR-PUCCH present in the slot, generating (208) a SR, - appending (209) the SR to the HARQ-ACK, - transmitting (211) the SR appended to the HARQ-ACK.

摘要： A method for arranging transmission of SSBs comprises transmitting (S1), from a first TRXP of a cellular telecommunication system, of first SSBs at a carrier. The first SSBs define a first cell. The first cell is unique for the first 5TRXP. The method further comprises transmitting (S2), from the first TRXP, of second SSBs at the carrier. The second SSBs define a second cell. The second cell is a combined cell of the first TRXP and at least one neighbouring, second TRXP. A method for cell assignment based on multiple SSBs is also disclosed, as well as TRXPs and network nodes for implementing the methods.

摘要： A method by a network node for configuring a wireless device to report Channel State Information (CSI) includes computing an N-port Channel State Information-Reference Signal (CSI-RS) resource configuration. The N-port CSI-RS resource configuration includes a number of antenna ports, N, without Code Division Multiplexing (CDM), and N is greater than one. At least one antenna port associated with the N-port CSI-RS resource configuration overlaps with at least one antenna port group associated with an M-port CSI-RS resource configuration with CDM. The network node transmits CSI-RS over the N-port CSI-RS resource configuration to a wireless device for CSI computation and receives CSI from the wireless device according to the N-port CSI-RS resource configuration.

摘要： A method by a wireless device for computing channel state information (CSI) includes obtaining an overlapping N-port CSI-RS resource definition that overlaps with an M-port CSI-RS resource definition. A number N of ports associated with the overlapping N-port CSI-RS resource definition is less than a number M of ports associated with the M-port CSI-RS resource definition. The wireless device calculates N-port CSI based on the overlapping N-port CSI-RS definition and reports the N-port CSI to a network node.

摘要： According to some embodiments, a method of operating a network node is provided. A first information element IE is provided including an indication of an added synchronization signal block/physical cell identity SSB/PCI. The indication of the added S SB/PCI indicates an SSB and associated PCI that are associated with a radio link. A second IE is provided including the indication of the added SSB/PCI. The second IE relates to at least one of channel state information CSI, radio link monitoring, uplink power control, and/or uplink spatial relations. A control message including the first IE and the second IE is transmitted to a user equipment UE, to enable the UE to perform a radio link monitoring function on the radio link.

摘要： A method of controlling radio transmission in a wireless communication network is described, the method comprising a radio device (10; 400; 700) receiving an indication of a set of first signals (31, 32, 33, 34, 35, 36) for associating the set of first signals (31, 32, 33, 34, 35, 36) with a second signal. The method comprises the radio device (10; 400; 700) receiving at least one of the first signals (31; 32, 33, 34, 35, 36); and in response to the indication, the radio device (10; 400; 700) estimating at least one parameter of the second signal based on the at least one received first signal. The method further comprises, based on the at least one estimated parameter, the radio device (10; 400; 700) processing at least one radio transmission (21) from the wireless communication network.

摘要： According to certain embodiments, a method performed by a wireless device comprises initiating a random access procedure in which the wireless device sends a Physical Random Access Channel, PRACH, preamble to a network node and applying a receiver configuration for receiving an access response. The receiver configuration is determined based at least in part on whether a many-to-one association exists between (a) a downlink signal that can be used for beam selection prior to initiating the random access procedure, and (b) PRACH preamble indices.
