摘要： Methods and apparatus in a fifth-generation wireless communications network, including an example method, in a wireless device, that includes determining a reporting quality threshold for a parameter related to channel state information (CSI); performing a measurement for each of a plurality of beams from a first predetermined set of beams for evaluation; evaluating the measurement for each of the plurality of beams against the reporting quality threshold; discontinuing the performing and evaluating of measurements in response to determining that the reporting quality threshold is met for one of the beams, such that one or more beams in the first predetermined set of beams are not measured and evaluated; and reporting, to the wireless communications network, CSI for the one of the beams.

摘要： The present disclosure relates to a first radio node configured for orthogonal frequency division multiplexing (OFDM), comprising a receiver, a transmitter, a processor and a memory storing instructions executable by the processor for causing the transmitter in a first mode of operation with a first subcarrier spacing f1: to transmit a sequence of prefixed OFDM symbols, and in a second mode of operation with a second subcarrier spacing f2: to transmit a sequence of prefixed OFDM symbols, wherein the sequence of transmitted OFDM symbols is aligned with a predefined repeating radio frame, which is common to both the first and second modes of operation, or with an integer multiple of the predefined repeating radio frame; and the first and second subcarrier spacings are related by an integer factor, f1/f2=p or f1/f2=1/p, with p≠1 integer.

摘要： Mechanisms for efficient transmission of large amount of download data from a base station to a user equipment in a multi-carrier that minimizes power consumption on the user equipment are described. When multiple component carriers are to be used to transmit the download data, the base station informs the user equipment. The base station transmits on the anchor carriers without wait after informing the user equipment and transmits on the non-anchor carriers after waiting a predetermined delay. The predetermined delay provides time to allow the user equipment to activate the receiving resources and be ready to receive the download data over the non-anchor carriers. In this manner, the user equipment can be in a power conservation mode and activate the receiver resources only when needed.

摘要： In one aspect, a wireless relay node operating in a wireless communications network obtains (602), for each of one or more other wireless relay nodes, information indicating a muting pattern for muting of synchronization signal blocks, SSBs, by the other wireless relay node. The wireless relay node performs (604) measurements of SSBs and muting of SSB transmissions based on the obtained information.

摘要： There is disclosed a User Equipment, UE, for a Radio Access Network. The UE is adapted for transmitting acknowledgement signaling pertaining to downlink data, the downlink data having one or more downlink data elements. The acknowledgement signaling has an uplink signaling format having one or more acknowledgement substructures, each of the substructures carrying acknowledgement information pertaining to a downlink data element. Each of the acknowledgment substructures is mapped to a different of the downlink data elements based on at least one acknowledgement position indication provided in downlink control signaling received by the UE. The disclosure also pertains to related devices and methods.

摘要： Coordinated multi-point transmission of user data from a first cell serving a wireless terminal and a neighboring second cell site is performed. The first cell site maps control signals and user data to time-frequency resources according to a first mapping pattern. The second cell site maps control data and traffic data to time-frequency resources according to a second mapping pattern. A wireless terminal extracts user data according to the first mapping pattern and detects a control element transmitted by the first cell site. The control element indicates that user data associated with the control element is mapped to the time-frequency resources according to the second mapping pattern. In response, the wireless device extracts user data according to the second mapping pattern from time-frequency resources of a second transmission for the wireless terminal transmitted from the second cell site.

摘要： The disclosure relates to a method of operating a wireless device. The method comprises receiving (10), from a network node, control information indicating a timing of a scheduled transmission or reception. The method further comprises determining (20) at least one slot or symbol for the scheduled transmission or reception based on the control information indicating the timing, wherein the determining is dependent on whether the wireless device is configured with a semi-static time division duplex, TDD, uplink-downlink allocation or not. The method also comprises performing (30) the scheduled transmission or reception in the determined at least one slot or symbol.
