Embodiments of interference coordination for aerial vehicle user equipment (UE) are described. In some embodiments, a base station (BS) is configured to select a subset of time-frequency resources dedicated for use in serving aerial vehicle UEs and communicate with the aerial vehicle UEs via the subset of time-frequency resources. In some embodiments, the BS may transmit signaling to a neighbor BS that indicates the BS has dedicated the subset of time-frequency resources for serving aerial vehicle UEs and the subset of time-frequency resources to be used. The BS may receive an indication from the neighbor BS that a neighbor BS is to dedicate the subset of time-frequency resources to serve aerial vehicle UE, and based on the indication, the BS may reduce transmission activities in the subset of time-frequency resources, including refraining from transmitting or reducing an amount of information or power level of signaling to the aerial vehicle UEs.

A transmitting device may select frequency domain resources for an alert transmission based on a severity level of the alert transmission. The transmitting device may determine a severity level of an alert transmission to be transmitted on one or more available channels. The transmitting device may determine a presence of one or more systems configured to transmit on one or more neighbor channels of the one or more available channels. The transmitting device may select, for the alert transmission, frequency domain resources within the one or more available channels based on the presence of the one or more systems and the severity level. The frequency domain resources for a highest severity level transmission are spaced further apart from the one or more neighbor channels in the frequency domain than resources for a lower severity level transmission. The transmitting device may transmit the alert transmission on the frequency domain resources.

Systems and method for configuring and providing uplink control information (UCI) multiplexing on physical uplink shared channel (PUSCH) transmissions are disclosed. In embodiments, a base station configures and signals, to a user equipment (UE) a plurality of sets of beta-offset values to be used by the UE for multiplexing a UCI transmission of a first priority to a PUSCH transmission of a second priority. Each set of the plurality of sets of beta-offset values is configured based on the second priority of the PUSCH transmission. In embodiments, the UE determines whether the UCI transmission of the first priority is allowed to be multiplexed to the PUSCH transmission of the second priority, and multiplexes the UCI to the PUSCH when multiplexing of the UCI and PUSCH is allowed, using a beta-offset value from the plurality of sets of beta-offset values. Other aspects and features are also claimed and described.

Multiplexing of information may be useful in a variety of communication scenarios, such as communication of control information. For example, certain wireless communication systems may benefit from uplink control information multiplexing for downlink two orthogonal frequency division multiplexed symbol short transmission time interval and one millisecond transmission time interval. A method can include receiving, at a user equipment, a downlink assignment scheduling first downlink data transmission in a first transmission time interval duration. The method can also include determining when to provide acknowledgment feedback in an uplink corresponding to the scheduled downlink data transmission. The determination can take into account whether the user equipment is scheduled for downlink data transmission in a second transmission time interval duration. The second transmission time interval duration can be shorter than the first transmission time interval duration.

Methods, systems, and devices for wireless communication are described. A base station may transmit a paging indicator message to one or more user equipment (UEs) in a group of UEs. The base station may receive, based at least in part on the paging indicator message, a first response message from the one or more UEs. The first response message may be received using a resource that is shared with a random access channel message for the group of UEs. The base station may transmit, based at least in part on the first response message, a second response message to the one or more UEs.

Wireless transmit/receive units (WTRUs) may include unmanned aerial vehicles (UAVs). The WTRUs/UAVs may cooperate to exchange channel busy ratio (CBR) and/or CBR statistics of one or more (e.g., all) the carriers that the WTRUs/UAVs monitors with each other for carrier selection/carrier reselection. A network may provide one or more inputs on carrier selection. For example, a network may provide one or more inputs on carrier selection based on the congestion that the network infers (e.g., through the CBR measurements reported by the WTRUs/UAVs and/or through its own measurements). MAC/PHY layers may be configured to perform transmit adaptation during PDCP packet duplication. For example, the carrier aggregation capability of receivers may be considered to adapt the number of transmissions per carrier. Based on the carrier aggregation capability of the receivers, the number of transmissions at one or more (e.g., every) carriers may be optimized jointly across carriers.

The present disclosure relates to methods and apparatuses for configuring a transport block scheduling interval, methods and apparatuses for determining a transport block scheduling interval, base stations, user equipment, and computer-readable storage media. A method of configuring a transport block scheduling interval includes: if scheduling of current machine type communication (MTC) user equipment (UE) is in a preset type, determining a corresponding transport block scheduling interval based on current capability information of the current MTC UE, and sending scheduling information to the current MTC UE through a physical downlink control channel (PDCCH). The current capability information includes a parameter indicating a scheduling processing capability level of the current MTC UE. The scheduling information includes the corresponding transport block scheduling interval.

Technology for a user equipment (UE) operable to perform adaptive time division duplexing (TDD) hybrid automatic repeat request (HARQ)-ACKnowledgement (ACK) reporting is described. The UE can implement an adaptive uplink-downlink (UL-DL) configuration received from an eNodeB. The UE can decode a downlink (DL) HARQ reference configuration received from the base station for a serving cell, wherein the DL HARQ reference configuration is for the implemented adaptive UL-DL configuration. The UE can decode a reference UL-DL configuration received from the base station via a system information block (SIB). The UE can encode HARQ-ACK feedback for transmission on an uplink channel of the serving cell in accordance with the DL HARQ reference configuration. The UE can perform uplink scheduling and the HARQ-ACK feedback based on the reference UL-DL configuration received from the base station via the SIB.

An embodiment of the present application discloses an HARQ process determination method, a network device and a terminal. The method comprises: the terminal determines HARQ process resource parameters; the terminal determines currently transmitted HARQ process resources on the basis of the HARQ process resource parameters; wherein, the current transmission is a non-dynamic transmission.

A user equipment in a wireless communications system supporting direct communication between user equipments selects a sidelink destination group (ProSe destination) associated with a sidelink logical channel having a highest logical channel priority among sidelink logical channels, which have data available for transmission in a sidelink control period (SC period) and which have not previously been selected in the same SC period, wherein each of the sidelink logical channels belongs to a sidelink destination group, each of the sidelink logical channels is allocated to a logical channel group (LCG) depending on a priority of said each sidelink logical channel and on a priority of the logical channel group, and the logical channel group is defined per sidelink destination group. The user equipment allocates radio resources to sidelink logical channels belonging to the selected sidelink destination group in decreasing priority order, and transmits the data using the allocated radio resources.
