摘要： A method performed by a network node, for handling link adaption (LA) of a channel. The network node obtains a channel quality value for each Transmission Time Interval (TTI) in a set of TTIs. The network node estimates a probability that a specific channel quality will occur from the obtained channel quality values for the set of TTIs based on a distribution of channel quality values. The network node further determines a set of transmission parameters which optimizes a target function of LA, based on the estimated probability for the channel quality, wherein each set of transmission parameters is mapped to a channel quality which is required for a successful reception.

摘要： Embodiments herein relate to a method performed by a first transmission point (12) out of at least two transmission points for estimating a channel quality gain of a wireless device (10) served by the first transmission point (12) in a wireless communication network (1). The first transmission point (12) coordinates transmissions with a second transmission point (13) out of the at least two transmission points in the wireless communication network (1). The first transmission point estimates the channel quality gain based on whether a first cell specific reference signal, CRS, configuration of the first transmission point (12) is using radio resources for a first CRS that are colliding or not with radio resources used for a second CRS of a second CRS configuration of the second transmission point (13) in the wireless communication network (1), and a utilization of frequency resources by the second transmission point (13).

摘要： The present disclosure is directed to a method and apparatus for controlling a Hybrid Automatic Repeat Request, HARQ, retransmission round-trip time for transmission in a wireless network. The method comprises to estimate (S41) one or more latency related transmission parameters and to select (S43) one or more of a plurality of predefined HARQ relaxation techniques based on the estimated one or more latency related transmission parameters. Transmission is scheduled (S44) using the selected one or more HARQ relaxation technique.

摘要： A method and an apparatus for uplink transmission control are disclosed. According to an embodiment, a base station determines a channel metric for indicating uplink channel condition between the base station and a terminal device. The base station determines an uplink transmission format that is to be used for an initial transmission from the terminal device, based on the channel metric such that a spectrum efficiency for the initial transmission can be maximized.

摘要： A method performed by a network node for managing power of Cell Reference Symbols, CRS, wherein the network node operates one or more cells and the network node is configured to transmit the CRS in a first power mode. When the network node identifies a first cell which is not actively serving any UEs, which cell is also referred to as an empty cell, the network node reduces the power of the CRS in the first cell in relation to the first power mode. By reducing the power of the CRS, the overall interference of the CRS from the empty cell is reduced, thereby enhancing the performance in cells actively serving UEs.

摘要： A method and a status manager for controlling status reporting from a data receiving node in a wireless communication of data with a data sending node. When detecting that the data receiving node should transmit a status report to the data sending node before a prescribed time limit expires, the data receiving node is triggered to transmit the status report either together with data if the data is pending for transmission from the data receiving node when the time left before the prescribed time limit is greater than a minimum duration, or alone if no data is pending when the time left before the time limit becomes shorter than the minimum duration.

摘要： Methods and systems for dynamically selecting a link adaptation policy, LAP. In some embodiments, the method includes generating a machine learning, ML, model, wherein generating the ML model comprises providing training data to an ML algorithm. The method further includes using channel quality information, additional information, and the ML model to select a LAP from a set of predefined LAPs. In some embodiments, the additional information comprises: neighbor cell information about a second cell served by a second TRP, distance information indicating a distance between a UE and a first TRP, and/or gain information indicating radio propagation gain between the UE and the serving node. The method further includes the first TRP transmitting second data to the UE using the selected LAP.

摘要： According to some embodiments, a method in a wireless device comprises: receiving a control channel (e.g., physical downlink control channel (PDCCH)) that includes control information that indicates a set of time and frequency resources allocated for the wireless device to receive a data transmission; determining that the set of time and frequency resources allocated for data transmission overlaps with a control resource region (e.g., control resource set (CORESET)); and receiving the data transmission in the set of time and frequency resources allocated for data transmission. The control information may include a bitmap that indicates at one or more groups of time and frequency resources excluded/included for the data transmission region.

摘要： A method and system for selectively activating and deactivating secondary cells in a wireless communication system are disclosed. According to one aspect, the invention provides a finite state machine having a plurality of states facilitating secondary cell activation and deactivation decisions. The states of the finite state machine include a deactivated state and an activated state. In the deactivated state, a secondary cell is deactivated and a media access control element, MAC CE, for deactivation is sent to the UE. The base station in the deactivated state is not allocating resources for maintaining transmission on the secondary cell. In the activated state, the secondary cell is active and a MAC CE for activation is sent to the UE. In the activated state, the base station is ready to transmit on the secondary cell.
