摘要： The present disclosure relates to control information signalling in mobile communications, to uplink control information signalling and physical uplink control channels in wireless communications. The proposed technique relates to methods transmitting a physical uplink control channel, and for adapting, selecting, or determining uplink control channel structures depending on the numerology used for the physical uplink control channel transmissions. The disclosure also relates to corresponding devices and to a computer program for executing the proposed methods, and to a carrier containing said computer program. The disclosure proposes a method, for use in a wireless device, for transmitting a physical uplink control channel comprising transmitting uplink control information, UCI, to one or more radio nodes on a physical uplink control channel having a physical uplink control channel structure being based on at least one numerology configured for or used by the wireless device for transmitting the physical uplink control channel.

摘要： A method and apparatus are disclosed. A wireless device (WD) configured to communicate with a network node is provided. The WD includes a radio interface and processing circuitry configured to: if a configured frequency hopping distance results in a resource allocation at two edges of a slot, apply a modified resource allocation that avoids resource allocation at two bandwidth part, BWP, edges. The modified resource allocation corresponds to a frequency hopping distance different from the configured frequency hopping distance. The radio interface and/or processing circuitry is further configured to transmit using the modified resource allocation.

摘要： There is disclosed a method of operating a user equipment in a radio access network. The method includes transmitting acknowledgement information reporting on subject transmissions based on a HARQ codebook. The HARQ codebook indicates a bit pattern of the acknowledgement information. The bit pattern has a plurality of subpatterns, each subpattern being associated to a different subdivision of a reception time interval to which the acknowledgement information pertains. Each subpattern includes a predetermined number of bits of acknowledgement information associated to subject transmissions of the subdivision. There are also disclosed related methods and devices.

摘要： A transmit power control (TPC) method and a user equipment (UE) of a telecommunications network utilizing the TPC method. The UE receives TPC commands intended for traffic and control channels. The TPC commands are separately identified by logical or physical resources associated with the channels. When the traffic and control channel TPCs occupy the same resources, the UE applies common power control commands to the traffic and control channels. When the traffic and control channel TPCs occupy different resources, the UE applies separate power control commands to the traffic and control channels.

摘要： Performing random access process. In one aspect, there is a method performed by a network function. The method comprises the network function generating system information and the network function broadcasting the system information. The system information comprises i) first power information for use by at least a first set of communication devices and a second set of communication devices in determining a transmit power, and ii) second power information for use by the first set of communication devices, but not the second set of communication devices, in determining the transmit power.

摘要： The technology described in this case facilitates random access by a user terminal with a radio base station. A user terminal determines one of a first type of uplink scrambling sequences and generates a random access message using the determined one of the first type of uplink scrambling sequences. The random access message is transmitted to the base station. The user terminal receives from the base station a second, different type of uplink scrambling sequence and uses it for subsequent communication with the radio base station. For example, the first uplink scrambling sequences may be specifically associated with the radio base station's cell area or a random access radio channel associated with the radio base station, but they are not specifically assigned to any user terminal, and the second uplink scrambling sequence may be selected from a second set of uplink scrambling sequences specifically assignable to individual user terminals.

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 present disclosure relates power control in wireless communications, to methods for open loop power control for setting the initial uplink transmission power for a wireless device capable of operating in multiple frequency bands. The disclosure includes methods for transmitting an uplink signal in an uplink channel of a first frequency band using an initial transmission power based on measurements of reference signals in the first frequency band when the received downlink channel is in a second frequency band not overlapping with the first frequency band. The disclosure also relates to corresponding devices and to a computer program for executing the proposed methods. Further, embodiments relating to a host computer and activities therein, are also provided.
