摘要： Methods, systems, and devices for wireless communications are described. In some wireless communications systems, devices may implement carrier aggregation and shortened transmission time intervals (sTTIs) for downlink transmissions. To improve downlink throughput with a reduced feedback latency, the system may implement a modified hybrid automatic repeat request (HARQ) timeline. For example, a base station may configure a first component carrier with a TTI or sTTI for downlink that is longer than an sTTI for a second uplink component carrier. The base station and a user equipment (UE) may operate using a HARQ timing for the first component carrier that is based on the shorter sTTI for the second component carrier. The base station may transmit a downlink transmission using the longer TTI or sTTI for greater carrier aggregation, and the UE may send a downlink HARQ acknowledgment (ACK) message in response according to the HARQ timing for reduced latency.

摘要： Systems, methods and instrumentalities are disclosed for uplink transmission without an uplink grant. A wireless transmit/receive unit (WTRU) may receive a grant free configuration from a network node (e.g., a NodeB). The grant free configuration may be associated with grant free uplink (UL) transmission. The grant free configuration may indicate a first access resource set and a second access resource set. The WTRU may determine that data needs to be transmitted in an UL transmission. The WTRU may compare requirements associated with the data to first characteristics associated with the first access resource set and second characteristics associated with the second access resource set. The WTRU may select the first access resource set based on the comparison of the requirements to the first characteristics and the second characteristics. The WTRU may transmit the data in the uplink without receiving a grant from the network node (e.g., NodeB).

摘要： In a packet transmission method, an error protection mechanism for HARQ feedback jointly codes successive acknowledgement messages to improve reliability. Successive acknowledgement messages are channel encoded into feedback signals using a convolutional code with rate k/m (see e.g. Lin & Costello Error Control Coding Prentice Hall 1983). With convolutional codes one input block of k information bits arrives per epoch and is coded into an output block of m>k coded bits. The coded signal at the current epoch depends on the input at the current epoch and the λ-1 previous input blocks (λ is called the code constraint length).The decoder introduces a delay when decoding HARQ acknowledgements messages but this delay is more than compensated the improved performance and the elimination of the large delays due to NACK to ACK errors.

The wireless access interface provides communications resources arranged in time divided units of a carrier frequency bandwidth providing a plurality of blocks of communications resources, each of the time divided units comprising on a downlink of the wireless access interface a control channel for transmitting control channel messages and a shared channel, the control channel message allocating communications resources of the shared channel to the communications devices to receive the signals from the one or more infrastructure equipment. The infrastructure equipment is configured to transmit data, as a plurality of data units, to the one or more communications devices, each data unit being encoded for transmission in accordance with a repeat request-type process, the encoding providing an indication of whether the data has been received correctly by a communications device. Each of the data units is transmitted in one of a repeating number of consecutive time divided units according to a separately controlled repeat request-type process. The transmitter is configured to transmit a control message allocating resources of the shared channel for receiving a data unit of a repeat request-type process which is one or more time divided units after a time divided unit in which the control message is transmitted, and the number of repeat request-type processes in the repeating pattern of time divided units is increased from a first number in the first mode to a second number in the second mode.
