摘要： There is provided a method, performed by a network node, for enabling uplink power control in a wireless network. The method comprises assigning (S1) a transmit power for downlink transmission of a reference signal, wherein the reference signal is to be used for power control of at least one uplink transmission. The method further comprises determining (S2) a reference signal transmit power parameter providing a fictitious value for the transmit power of the reference signal that is different from the assigned transmit power. The method also comprises transmitting (S3) the reference signal transmit power parameter to at least one wireless device to enable the wireless device(s) to perform transmit power determination for the uplink transmission(s) at least partly based on the fictitious value for the transmit power of the reference signal.

摘要： A method performed by a network node for controlling power in a Random Access (RA) procedure is provided. The RA procedure is from a UE to a first Transmission and reception Point (TRP) in a multi TRP cell in a wireless communications network. For each respective TRP out of a set of TRPs, network node calculates a smallest distance between this TRP and each respective other TRP comprised in the set of TRPs. The set of TRPs are comprised in the multi TRP cell. The network node obtains a minimum distance among the calculated smallest distances. Based on the minimum distance, the network node establishes a path loss difference towards each of the TRPs in the set of TRPs, as experienced by the UE. The network node calculates a target power based on the established path loss difference and a preamble detection sensitivity level. The target power is to be used.

摘要： A method performed by a network node for allocating reference signals to a set of sector carriers provided by the network node for a communication with a UE in a radio network is provided. The network node allocates reference signals to each respective sector carrier, by for each respective sector carrier, allocating a reference signal to the sector carrier, and a parameter representing the sector carrier. The network node transmits the reference signal in each respective sector carrier and evaluates a neighboring relationship between the sector carriers, to identify if two neighboring sector carriers within the one or more cells are allocated the same reference signal. When identified that two neighboring sector carriers are allocated the same reference signal within one or more cells comprising the sector carriers, the network node re-allocates at least one of the two neighboring sector carriers with another available reference signal.

摘要： It is disclosed a base station of a cell having at least a first and a second antenna sector, where the base station is distributed in terms of location and a method performed in said base station for determining an uplink power control target for a UE that is connected to the first antenna sector. The method comprises estimating (42, 504), in the at least the first and the second antenna sectors, a thermal noise floor; and determining (44, 516) the uplink power control target based on a maximum of the estimated thermal noise floors in all of the at least the first and the second antenna sectors. The method improves uplink performance of cells with antenna sectors having different receiver sensitivity, and provides enhanced observability of UEs for cells extending over multiple base stations.

摘要： User equipments, network nodes, and systems are described to transmitting and receiving a physical uplink control channel, PUCCH. For example, a user equipment may receive configuration information from a network node. The configuration information may indicate a plurality of cells available for transmitting or for receiving the PUCCH, the plurality of cells including a reference cell and may indicate a plurality of cell index values respectively associated with a plurality of slots of the reference cell, each cell index value indicating a respective designated cell from among the plurality of cell. The user equipment may receive a timing indicator indicating a reference slot from among the plurality of slots of the reference cell and may transmit the PUCCH using the respective designated cell indicated by the cell index value associated with the reference slot.
