摘要： Methods and apparatus are provided for determining timing of resources in an integrated access and backhaul, IAB, node (200). In one example, a method (1300), is performed by an integrated access and backhaul, IAB, node (200), the method comprising: determining (s1302) one or more timing offset for a time resource, the offset being in relation to a mobile termination, MT, and a distributed unit, DU, resource of the IAB node, and providing (s1304) to a parent IAB node (300), information related to the one or more timing offset of the IAB node.

摘要： There is disclosed a user equipment, UE, for a Radio Access Network, the UE being adapted for sidelink communication on a sidelink, the UE further being adapted for transmitting acknowledgement signaling pertaining to sidelink data. The sidelink data includes one or more data elements and the acknowledgement signaling has a signaling format comprising one or more acknowledgement substructures. Each of the substructures carries acknowledgement information pertaining to one of the data elements. Further, each of the acknowledgment substructures is mapped to a different one of the data elements based on at least one acknowledgement position indication provided in control signaling received by the UE. The disclosure also pertains to related devices and methods.

摘要： A set of different pilot structures are designed for use in different environments and/or different user behaviours that are expected to occur in a cell. The radio conditions for a user are estimated. Each user is then assigned an area (108A-E) in resource space for its communication, which has a suitable pilot configuration. In one embodiment, the entire resource space is provided with different pilot structures in different parts (110A-D). In advance and allocation of resources to the users are then performed in order to match estimated radio conditions to the provided pilot structure. In another embodiment, allocation is performed first, and then the actual pilot structure is adapted within the allocated resource space area to suit the environmental conditions.

摘要： The invention relates to a technique for performing a random access procedure over a radio interface, for example between a mobile terminal and a radio base station of a mobile network. A method aspect of the invention comprises the steps of transmitting a synchronization request for synchronization information; receiving synchronization information in response to the synchronization request; and transmitting, based on at least one transmission parameter adjusted in accordance with the synchronization information, a resource request for data transmission resources.

摘要： Limited uplink bandwidth radio network devices are supported on wide bandwidth uplink carriers by configuring and controlling the use of multiple control regions within the uplink carrier bandwidth. In some embodiments, the total bandwidth of the uplink carrier is divided into a plurality of sub-band portions, wherein each sub-band portion includes at least one control region nominally dedicated to the transmission of uplink control signaling. Radio network devices are configured with a specified portion of the uplink carrier bandwidth for use for uplink transmission, which includes at least one control region. Radio network devices may be provisioned or provided with information regarding control regions reserved for control signaling by other radio network devices. The radio network devices may be dynamically configured to allow or suppress uplink data signaling in specified control regions, or portions thereof.

摘要： More than one set of sounding signal configuration parameters are determined for the same mobile terminal. The mobile terminal uses the sets of configuration parameters to generate different sounding reference signals which can be used for different purposes such as estimating timing and channel quality. In one embodiment, a method of configuring uplink sounding transmissions by mobile terminals in a wireless communication network is characterized by determining different sets of configuration parameters for sounding signal transmissions for a given mobile terminal. The different sets of configuration parameters are transmitted to the mobile terminal, allowing the mobile terminal to generate different sounding signals for different uses by the wireless communication network.

摘要： In an aspect, a transmitting node schedules a downlink transmission to a first UE over a first transmission interval having a predetermined length and starts the downlink transmission to the first UE in the first transmission interval. The transmitting node stops the downlink transmission to the first UE prior to an end of the first transmission interval to create a first end of a transmission hole in the downlink transmission to the first UE and resumes the downlink transmission to the first UE at a second end of the transmission hole. The transmitting node may receive an uplink transmission from a second UE or transmit a higher priority transmission, within the transmission hole.

摘要： Systems and methods are provided for allocation of acknowledgement resources. In an embodiment, a method of transmitting control information to a communication network may be implemented in a wireless device. The method may include being configured with at least two physical uplink control channel (PUCCH) opportunities, each of the at least two PUCCH opportunities identifying uplink resources to be used for transmitting control information to the communication network. The method may further include receiving an acknowledgement resource indication (ARI) indicating one of the configured at least two PUCCH opportunities to be used for transmitting control information associated with the DL transmission.

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.
