摘要： A method performed by a network node for restraining false preamble detections in a Random Access, RA, procedure from a User Equipment, UE, to a first Transmission and Reception Point, TRP, in a multi TRP cell in a wireless communications network. The multi TRP cell comprising a set of TRPs. The network node calculates (602) an average coverage range per TRP in the set of TRPs based on an obtained coverage range for each respective TRP out of the set of TRPs. The network node determines (603) an adjustment parameter, such that the adjustment parameter multiplied with the calculated average coverage range is below a first threshold. The network node determines (604) a parameter related to a preamble detection zone. The parameter is based on: The adjustment parameter and the calculated average coverage range. The parameter is further based on any one or more out of: A false preamble detection rate according to historical data, and a success rate for RA according to historical data. The network node configures (606) the respective TRPs in the set of TRPs to use the determined parameter related to the preamble detection zone, in order to restrain false preamble detections in the RA procedure between the UE and the first TRP.

摘要： Method for handling of DL bandwidth, which method is performed by a first network node. The network node determines an adapted available DL bandwidth based on the available DL bandwidth and/or the blocked DL bandwidth. It further determines that the adapted available DL bandwidth does not coincide with a bandwidth of the 3GPP standard. When the DL bandwidth does not coincide with a bandwidth of the 3GPP standard, the network node selects the next larger standard 3GPP DL bandwidth, or in case no larger standard 3GPP DL bandwidth is available, selects the largest available standard 3GPP DL bandwidth. The network node further blocks transmission in PRBs which are completely or partially located in the blocked DL bandwidth, based on the available DL bandwidth and/or blocked DL bandwidth.

摘要： A method performed by a network node for restraining Random Access, RA, false preamble detections in an RA procedure from a User Equipment, UE, to a first Transmission and Reception Point, TRP, in a multi-TRP cell of a wireless communications network is provided. Each TRP out of a set of TRPs has detected one or more respective preambles. The network node obtains (501) for each preamble detected by a TRP out of the set of TRPs, a respective detection comprising a preamble Identity, ID, a signal value, which signal value is related to a signal strength of the received preamble, and a TRP ID associated with the respective TRP detecting the preamble. The network node aggregates (502) the obtained detections into a set of detections. The network node identifies (503) from the set of detections, one or more detections comprising duplicate preamble IDs. For each of the one or more detections comprising duplicate preamble IDs, the network node reduces (504) the set of detections, by removing the duplicate detection with the signal value related to the lowest signal strength. The network node further reduces (505) the set of detections, by removing one or more detections identified as potential false detections based on one or more out of: (A) a propagation delay of the preamble transmitted from the UE to the respective TRPs, and a location of the UE, and (B) a signal value related to a signal strength in a detection out of the set of detections being lower than the signal value related to the strongest signal strength in the set of detections by at least a threshold value. The network node identifies (506) one or more candidates to be the first TRP based on the further reduced set of detections.

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 User Equipment (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 (601) 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 (602) a minimum distance among the calculated smallest distances. Based on the minimum distance, the network node establishes (603) a path loss difference towards each of the TRPs in the set of TRPs, as experienced by the UE. The network node calculates (604) a target power based on the established path loss difference and a preamble detection sensitivity level. The target power is to be used by the UE for transmitting a preamble in the RA procedure to the first TRP.

摘要： Scheduling information for a wireless device may be transmitted from a first node of a network to the second node of the network wherein the scheduling information defines a plurality of time slots for UpLink transmission from the wireless device. After transmitting the scheduling information to the second node, a UL signaling grant may be transmitted to the wireless device for one of the time slots defined by the scheduling information. A UL transmission may be received from the wireless device at the first node over the time slot of the UL signaling grant. Information may be received from the second node relating to the UL transmission over the time slot of the UL signaling grant. The UL transmission may be processed at the first node using the information from the second node relating to the UL transmission from the wireless device.

摘要： A method includes a base station in a distributed antenna system having a set of antennas. For each antenna, the base station stores state information indicating that the antenna is either in a transmit state or a do_not_transmit state. For each antenna indicated by the state information for the antenna as being in the transmit state, the base station determines whether the antenna has been given a clear channel indication (CCI) for a next transmission time interval (TTI). At the next TTI, the base station transmits data to a UE, wherein the base station transmits the data to the UE using antennas included in said set of antennas that i) are indicated by the state information for the antenna as being in the transmit state and ii) have been given the CCI. The base station adjusts the state information in accordance with a transmit status.
