Abstract: A communication device may receive signaling indicative of an antenna beam direction in which a reference signal may be received by the communication device, and transmit a message responsive to receiving a reference signal from another communication device during monitoring of the antenna beam direction indicated by the received signaling. At least one of the communication devices is an aerial communication device. Considering a different perspective in a wireless communication network, the signaling indicative of antenna beam direction may be transmitted to the communication device, and signaling to cause the other communication device to transmit the reference signal in the antenna beam direction may be transmitted to the other communication device.

Abstract: Systems and methods are provided for transmitting and receiving pre-emption indications. The pre-emption indication is transmitted every K symbols or slots, on a group-common physical downlink control channel. The pre-emption indication is in respect of a group of K symbols or slots preceding a symbol or slot containing the group-common pre-emption indication. The group-common pre-emption indication indicates, for the group of K symbols or slots, which resources are pre-empted. The base station schedules resources for first downlink traffic, and transmits the scheduled first downlink traffic subject to pre-emption, and transmits second downlink traffic by pre-empting resources for the first downlink traffic. On the UE side, the UE receives the pre-emption indication. The UE receives its scheduled traffic taking into account the pre-emption indication.

Abstract: Embodiments of the present application pertain to control information for scheduling a transmission resource for downlink and uplink communications between one or more TRP and one or more UE. One Physical Downlink Control Channel (PDCCH) for DL control information transmission is assumed to carry at least one assignment or scheduling information block for at least one Physical Downlink Shared Channel (PDSCH) for DL data transmission or for at least one Physical Uplink Shared Channel (PUSCH) for UL data transmission. Embodiments of the present application provide methods of providing configuration information that can be used by a user equipment (UE) to determine transmission mode for the PDSCH and PUSCH as well as information to determine where to monitor for the PDSCH, PUSCH and PUCCH information.

Abstract: Embodiments of this disclosure improve the reliability of blind decoding when beamforming is used by having a user equipment (UE) receive a single downlink control information (DCI) message with different transmission and/or reception parameters. In some embodiments, a UE receives more than one set of configuration parameters, where any two sets of configuration parameters out of the more than one set of configuration parameters have at least one different parameter. The UE may receive two sets of configuration parameters each having a different transmission modes, but the same search space type. Additional examples are also provided.

Abstract: With sidelink reservation signals sent together with the sidelink data, there is the possibility of interference with other sidelink signals. In order to address this, systems and methods are provided in which a first UE transmits a reservation signal to indicate at least one time-frequency resource for transmitting sidelink data. Following this, the first UE transmits at least one sidelink data transmission to a second UE using the at least one time-frequency resource indicated by the reservation signal. The reservation signal is transmitted before the at least one sidelink data transmission signal so that a third UE may detect the reservation signal and use the reservation signal to avoid using the at least one time-frequency resource indicated in the reservation signal.

Abstract: Systems and methods for early termination of feedback in respect of sidelink transmissions are provided. A first UE transmits at least one sidelink (SL) transmission of a first set of SL transmissions to a second UE, the first set of SL transmissions comprising an initial SL transmission and a set number of SL retransmissions. If no ACK is received, then the first UE transmits the set number of retransmissions. On the other hand, if an ACK is received, then the first UE transmits fewer than the set number of SL retransmissions when an ACK is received from the second UE before the set number of SL retransmissions has been completed. By transmitting fewer than all of the set number of SL retransmissions, resources can be freed up for other purposes. The approach may be used for SL configured grant transmission.
