Abstract: 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.

Abstract: Systems, methods, apparatuses, and computer program products for aperiodic channel state information (CSI) reporting for enhanced carrier aggregation are provided. One method includes transmitting, by a network node, a configuration of at least two aperiodic channel state information (A-CSI) reporting modes per one or more configured downlink (DL) component carriers (CC) to at least one user equipment. The method may also include transmitting an aperiodic channel state information (A-CSI) trigger to the at least one user equipment. The transmitting of the A-CSI trigger may cause the at least one user equipment to dynamically switch between the two configured aperiodic channel state information (A-CSI) reporting modes.

Abstract: Systems, methods, apparatuses, and computer program products for indicating network node fixed frame period (FFP) or UE FFP. A UE may transmit an uplink (UL) signal at a start of a UE FFP. A network node may respond by allocating UL resource(s) for subsequent UE transmission(s). The network node may implicitly signal, in Downlink Control Information (DCI), whether a UL transmission is to be transmitted based on assuming a UE FFP or a network node FFP for the UL transmission. The UE may make this assumption based on a cyclic prefix (CP) extension indication in DCI. For example, for certain CP extensions, the UE may determine to transmit the UL transmission according to the UE FFP. Otherwise, the UE may determine to transmit the UL transmission according to a network node FFP.

Abstract: Example embodiments of the present disclosure relate to a solution for performing an operation related to a listen-before-talk (LBT) process for a transmission. In an aspect, an apparatus determines a duration of a gap between an end point of a first transmission to be transmitted by a further apparatus and a start point of a cyclic prefix extension prior to a second transmission to be transmitted by the apparatus. The apparatus performs an operation related to an LBT process for the second transmission based on comparisons between the duration of the gap and a plurality of threshold durations associated with a plurality of types of LBT processes. Example embodiments of the present disclosure can increase or even maximize the likelihood of the success of LBT processes.

Abstract: Example embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of the adjustment of the Timing Advance (TA). The method comprises determining a channel occupancy time structure for accessing a radio channel between the first device and a second device, the channel occupancy time structure indicating a set of time-domain resources for accessing the radio channel; and setting a timing advance for a transmission from the first device to the second device based on the channel occupancy time structure. In this way, a dynamic adjustment of TA is allowed at the UE, which ensures that a desire duration of the gaps of the channel occupancy at different transmission scenarios.

Abstract: Embodiments of the present disclosure relate to bit reduction in resource information. According to embodiments of the present disclosure, the number of bits to indicate the resource allocation is reduced and the network device generate the control information based on an offset associated with the bit reduction. In this way, multiple transmission opportunities for the transmission of Msg3 of the random access procedure are provided without increasing the signaling overhead.
