摘要： A user equipment is configured (610) with at least two collections of uplink resources to be used for transmitting control information to a communication network. The UE receives (620) an assignment of radio resources to be used for receiving a downlink transmission from a base station of the communication network. The UE receives (630) an acknowledgement resource indication, ARI, indicating one of the configured collections of uplink resources to be used for transmitting control information associated with the DL transmission. Further, the UE transmits (640) the control information to the base station on at least a subset of the indicated collection of UL resources. In example embodiments, the indicated collection of uplink resources comprises a plurality of selectable uplink resource sets. The control information is transmitted on one of the uplink resource sets which corresponds to an operational state of the communication network.

摘要： Systematic size matching procedures for downlink control information, DCI, provide exact instructions on how DCI size matching is to be performed in a NR wireless system, to meet predetermined limits for how many different DCI sizes may be monitored by a user equipment, UE. With these procedures, consistent and exact DCI size matching can be performed while keeping blind decoding procedures manageable, ensuring common understanding of DCI contents between the UE and the network.

摘要： A method and apparatus according to the present invention addresses and/or prevents lost protocol synchronization in HARQ systems caused by ACK/NACK errors. One embodiment detects lost synchronization errors for NDI-based retransmission protocols and restores synchronization by sending an explicit RESET message. In response to the RESET message, the transmitter aborts the transmission of a current PDU and transmits a new PDU and corresponding NDI. Another embodiment prevents protocol synchronization errors by sending scheduling grants on a packet by packet basis. The receiver sends a subsequent explicit scheduling grant to the transmitter based on an error evaluation of a received PDU. The transmitter will not send the next PDU unless it receives the subsequent explicit scheduling grant.

摘要： The present invention relates to a radio node (212), a wireless device (220) and methods performed by the radio node (212) and the wireless device (220) for communicating in a wireless communication system (200). The wireless device (220) is configured with cells on at least two component carriers, CCs, available to the wireless communication system (200) for communication with the wireless device (220). Each one of the at least two CCs is associated with at least one CC group out of a set of CC groups. The radio node (212) transmits control information to the wireless device (220) indicating a CC group. The transmitted control information applies to at least one CC, which at least one CC is at least one of those CCs, out of the at least two CCs, that are associated with the indicated CC group. The wireless device (220) receives the control information from the radio node (212) and applies the received control information to at least one CC, which at least one CC is at least one of those CCs, out of the at least two CCs, that are associated with the indicated CC group.

摘要： A base station (20A) is configured to transmit user data to a wireless device (16A) upon a first carrier (22). The base station (20A) identifies, from a set of transmission resources that is nominally allocated for transmission of user data upon the first carrier (22), a subset of transmission resources that is also nominally allocated for transmission of a reference or control signal either by the base station (20A) upon a second carrier (24) or by a neighboring base station (20B) upon the first carrier (22). The base station (20A) selectively transmits user data to the wireless device (16A) upon the first carrier (22) exclusive of this identified subset of transmission resources. The device (16A) in some embodiments obtains information indicating that the base station (20A) is selectively transmitting user data upon the first carrier (22) exclusive of the subset in this way. Based on this information, the device (16A) recovers user data received upon the first carrier (22) exclusive of the subset of transmission resources.

摘要： A method in a wireless device for performing random access to a network node. The method comprises receiving a set of downlink beam-specific reference signals, BRS, from the network node, and determining a preferred BRS based on the received signal power for each BRS. The method also comprises selecting, based on the preferred BRS, a random-access resource to be used for transmitting a random-access attempt to the network node, as well as using the selected random-access resource when transmitting a random-access attempt to the network node, whereby the selection of random-access resource indicates to the network node which downlink beam is preferred by the wireless device to be used for downlink transmissions.

摘要： Methods and apparatuses disclosed herein enable the use of Demodulation Reference Signal, DMRS, sequences that are numbered relative to an overall system bandwidth (30), while simultaneously enabling wireless communication devices (12) to determine the DRMS sequence elements mapped to their scheduled bandwidths (36) within the system bandwidth (30). Advantageously, the wireless communication devices (12) need not know the system bandwidth (30), or even be aware of where their scheduled bandwidths (36) reside within the system bandwidth (30).

摘要： There are provided mechanisms for monitoring search spaces. A first method performed by a wireless device comprises receiving an OFDM symbol in a downlink slot. At least part of the OFDM symbol is included in a device-specific search space and in a common search space. The first method comprises monitoring the device-specific search space for at least one device-specific reference signal (RS) and monitoring the common search space for at least one non-device-specific RS. In a second method, a radio access network node transmits an OFDM symbol included in a device-specific search space and in a common search space. The device-specific search space contains a device-specific RS, or the non-device specific search space contains a non-device-specific RS, or both of these apply.

摘要： Radio communication systems, devices and methods for enabling variable subband configuration of one or more search spaces. In a first time interval, a UE attempts to decode one or more control channels on downlink or sidelink resources of a first subband configuration. In a second time interval, the UE attempts to decode one or more control channels on downlink or sidelink resources of a second subband configuration. The first subband configuration spans a first frequency range and the second subband configuration spans a second frequency range different from the first frequency range.
