Abstract: Systems, methods, apparatuses, and computer program products for channel access for semi-static uplink (UL) resources are provided. One method may include receiving, at a user equipment, an indication of at least one of time portions of channel occupancy time (COT) where the user equipment can use a first type of channel access for configured uplink (CUL) transmission or time portions where a second type of channel access is required prior to the configured uplink (CUL) transmission. The method may then include, based on the received indication, determining a channel access mechanism to use when transmitting on a configured uplink (CUL) resource.

Abstract: Various communication systems may benefit from a reduction in latency. For example, communication systems may benefit from an improved transmission of an uplink reference signal in an uplink channel. A method, in certain embodiments, includes determining by a user equipment a candidate location of a transmission of an uplink reference signal in a channel. The method also includes determining by the user equipment a triggering window associated with the candidate location of the transmission of the uplink reference signal in the channel. In addition, the method includes receiving an uplink grant for a data transmission from a base station. Further, the method includes transmitting the uplink reference signal based on the uplink grant being at least partially within the triggering window.

Abstract: Various communication systems may benefit from appropriate coordination of measurements for mobility or other reasons. For example, Long Term Evolution communication systems may benefit from signaling for uplink short transmission time interval transmissions. A method can include determining how a user equipment is to transmit with respect to a demodulation reference signal. The method can also include providing uplink grant to schedule the user equipment to transmit according to the determination.

Abstract: A method and apparatus may include receiving an uplink grant in a specific subframe of a frame and/or a physical hybrid-ARQ indicator channel transmission, for a physical-uplink-shared-channel transmission or retransmission on a special subframe. The method may also include determining that the uplink grant validates transmitting a physical-uplink-shared-channel transmission on the special subframe, or that the physical hybrid-ARQ indicator channel transmission validates transmitting a physical-uplink-shared-channel retransmission on the special subframe. The method may also include determining transmission parameters for transmitting the physical-uplink-shared-channel transmission or retransmission. The method may also include transmitting the physical-uplink-shared-channel transmission or retransmission on the special subframe.

Abstract: An apparatus includes a processor; and a non-transitory memory including computer program code; wherein the memory and the computer program code are configured to, with the processor, cause the apparatus at least to: report at least two reported beams to a radio node; receive a configuration from the radio node for at least two configured beams, the at least two configured beams comprising a primary beam and at least one secondary beam; attempt to decode data based on the primary beam, per monitoring occasion for a downlink channel, based on the received configuration; in response to a failure to decode the data based on the primary beam, attempt to decode the data based on the at least one secondary beam over the downlink channel; and transmit or receive information over a scheduling occasion using at least one of the at least two configured beams following a successful decoding attempt.

Abstract: It is provided a method, comprising checking if an option grant for an uplink transmission is received, wherein the option grant comprises, for a subframe, a first allocation option to start the uplink transmission and a second allocation option to start the uplink transmission, wherein the first allocation option is earlier in the subframe than the second allocation option; deciding if the uplink transmission is allowed at the first allocation option; starting the uplink transmission at the first allocation option if the option grant is received and the uplink transmission is allowed at the first allocation option; deciding if the uplink transmission is allowed at the second allocation option; starting the uplink transmission at the second allocation option if the option grant is received, the uplink transmission is not allowed at the first allocation option, and the uplink transmission is allowed at the second allocation option.

Abstract: A radio network sends to a user equipment (UE) an indication that reduced processing time associated with a reduced search space is operational for the UE. The reduced search space is a sub-set of a larger search space associated with a non-reduced processing time. The network sends to the UE within the reduced search space downlink control information (DCI) in subframe N that allocates to the UE a radio resource. If the allocated radio resource is uplink, the network receives uplink data from the UE on the allocated radio resource in a subframe spaced from the subframe N an amount of the reduced processing time (N+reduced processing time); and/or if the allocated radio resource is downlink the network sends downlink data to the UE on the allocated radio resource in subframe N and receives from the UE in reply feedback (ACK/NACK) signaling in a subframe N+reduced processing time.
