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: According to a first embodiment, a method may include receiving, by a user equipment, at least one downlink assignment indicating at least one multiplexing group indicator. The method may further include generating, by the user equipment, at least one hybrid automatic repeat request acknowledgement codebook in a sub-slot for each received multiplexing group indicator value. The method may further include determining, by the user equipment, whether more than one PUCCH resource associated with more than one multiplexing group indicator overlaps in time. The method may further include transmitting, by the user equipment, the highest priority codebook on the determined PUCCH resource and preventing, by the user equipment, transmission of the lower-priority HARQ-ACKs based on the at least one MGI indication in case an overlap in time has been determined. The method may further include transmitting, by the user equipment, the generated codebook on the determined PUCCH resource.

Abstract: Systems, methods, apparatuses, and computer program products for dynamic transmit diversity fallback are provided. One method may include configuring a user equipment with a maximum number of multiple-input multiple-output (MIMO) layers used for transmission mode 9 or transmission mode 10 scheduling, and performing, by a network node, at least one of transmission mode 9 or transmission mode 10 scheduling. The configuring may include indicating to the user equipment to use a modified mapping table providing transmit diversity fallback for the at least one of transmission mode 9 or transmission mode 10 scheduling.

Abstract: Various communication systems may benefit from efficient communications. For example, low latency long term evolution (LTE) systems may benefit from a short physical uplink shared channel (PUSCH) arrangement. A method may include operating a user equipment to follow a shortened transmission time interval. The shortened transmission time interval can be an integer number, L, of symbols in length. The method can also include sending a demodulation reference signal in at least a first symbol of the L symbols of the shortened transmission time interval.

Abstract: A method including transmitting from a base station (BS) at least one parameter for a first type of listen before talk (LBT) procedure to be used for uplink to be received by the base station; and configuring the base station (BS) for a different second type of listen before talk (LBT) procedure for downlink from the base station (BS). A method including receiving by a User Equipment (UE) at least one parameter for a first type of listen before talk (LBT) procedure; using the at least one parameter for uplink transmission from the User Equipment (UE); and receiving data on downlink to the User Equipment (UE) during a portion of a sub frame, where the portion is less than an entire subframe.
