摘要： A method performed by a first network node for coordinating reference signals, of at least one neighbouring network node for upcoming communications with UEs in a wireless communications network is provided. When a quality value of a reference signal assigned a specific index transmitted by a neighbouring network node, is an offset better than a quality value of a reference signal transmitted by the first network node, the first network node receives (501) one or more measurement reports from one or more UEs served in the first network node. The respective one or more measurement reports from the respective one or more UEs comprises: The quality value of the reference signal transmitted by that neighbouring network node and the index assigned to that reference signal for each of the at least one neighbouring network nodes, and a quality value of a reference signal transmitted by the first network node and the index assigned to that reference signal. Based on the one or more measurement reports, the first network node identifies (502) two network nodes among the at least one neighbouring network node and the first network node, that are assigned the same index to their respective transmitted reference signals. The first network node coordinates (503) the reference signals by configuring at least one of the two identified network nodes to switch any one out of: The index for its reference signals, or the direction of its reference signals.

摘要： A RAP detection procedure that can be used to find the best narrow beam in an efficient manner. In a first step, an access point correlates an incoming signal with appropriate RAPs and then selects at least one candidate RAP for further processing in at least one set of narrow beams that all reside within the coverage area of a wide beam with which the candidate preamble is associated. For each candidate RAP, a second step is executed including narrow beamforming and a PRACH receiver chain including threshold comparison.

摘要： The present disclosure relates to a method performed by a core network node (200) for enabling handling of data packets in a wireless communication system (101). The core network node (200) identifies a potentially malicious service data flow associated with a communication device (100). The core network node (200) assigns, to the potentially malicious service data flow, an identifier value to an identifier. The identifier value indicates that data packets associated with the potentially malicious service data flow should be handled according to a packet handling rule for potentially malicious data packets. The core network node (200) provides an identifier comprising the identifier value towards the communication device (100) towards at least one of an access node (300) that serves the communication device (100) in the access network (320), and a second core network node (103) that processes data packets to and from the communication device (100).

摘要： A method performed by a network node for allocating resources to a UE. The network node determines a system load of the network node for the UE. When the UE is capable of receiving control information on EPDCCH, the system load is determined based on a first and a second system load metrics on a physical resource shared by PDSCH and EPDCCH, which first load metrics comprises a load due to EPDCCH and a load due to multiplexed PDSCH and which second load metrics comprises a load due to multiplexed EPDCCH and a load due to PDSCH. When the UE is not capable of receiving control information on EPDCCH, the system load is determined based on the first system load metrics on the physical resource shared by the PDSCH and EPDCCH and a third system load metrics on a physical resource for carrying PDCCH. The network node further determines whether or not to allocate resources to the UE based on the determined system load metrics.

摘要： A method (300) for determining cells in which a preamble has been transmitted. The method includes obtaining (s302) N sample sets, wherein each one of the N sample sets comprises a set of M samples and each one of the N sample sets is associated with a different cell included in a set of N cells. The method also includes adding (s304) the N sample sets to create a first combined set of samples comprising M samples. The method also includes forming (s306) a first candidate set of one or more tuples based on the first combined set of samples and an initial set of tuples comprising a plurality of tuples, wherein each tuple comprises a candidate preamble and a candidate delay, and wherein each candidate preamble comprises a set of samples. The method further includes using (s308) the first candidate set of one or more tuples to determine, for each cell included in the set of cells, whether a preamble included in the first candidate set of tuples was transmitted in the cell.

摘要： Embodiments of a method in a base station for precoding a downlink transmission are disclosed. In some embodiments, the method comprises obtaining, for a time instant k, an estimate of a channel matrix for a wireless channel for a downlink from the base station to a wireless device and projecting the estimate of the channel matrix onto one or more sets of spatial orthonormal functions, thereby obtaining respective sets of coefficients. The method further comprises, for each set of spatial orthonormal functions, filtering the set of coefficients for the time instant k based on a filtering parameter that is specific to a downlink channel to be transmitted. The method further comprises generating beamforming weights using the filtered set of coefficients for at least one of the sets of spatial orthonormal functions, and precoding the downlink channel using the beamforming weights.
