    Abstract: Methods and apparatuses for network coding with a retransmission scheme are described. A first packet intended for a first destination node and a second packet intended for a second destination node are obtained. An initial transmission of the first packet to the first and second destination nodes is performed, and an initial transmission of the second packet to the first and second destination nodes is performed. A retransmission to the first and the second destination nodes is performed, where performing the retransmission includes generating cross-packet coded bits using a combination of one or more bits from the first packet and one or more bits from the second packet, where the cross-packet coded bits are scrambled using an identifier known to both the first and second destination nodes, and where the cross-packet coded bits, after scrambling, are used for the retransmission.

    Abstract: This application provides a method for determining a time-domain resource used for grant-free transmission. The method includes: obtaining, by a terminal device, a first time-domain period and a second time-domain period of grant-free transmission resources, where a size of the first time-domain period is P1 time units, a size of the second time-domain period is P2 time units, and P1 is greater than or equal to P2; obtaining, by the terminal device, a quantity k of grant-free transmission resources in the first time-domain period; and determining, by the terminal device based on the first time-domain period, the second time-domain period, and the quantity k of grant-free transmission resources in the first time-domain period, an index of a time unit in which a grant-free transmission resource used for grant-free transmission is located. In this way, grant-free transmission resources configured for the terminal device in two adjacent periods do not overlap.

    Abstract: Methods and apparatuses for performing MIMO transmissions are described. Retransmission schemes are described for MIMO transmissions. In an example, a transmitter node obtains a plurality of packets to be transmitted to an intended receiver node over a plurality of MIMO layers. A set of one or more cross-block check blocks is generated, where the set of one or more cross-block check blocks being is using a plurality of bits selected from across two or more packets to be transmitted over respective two or more MIMO layers. The set of one or more cross-block check blocks is transmitted over one or more MIMO layers.

    Abstract: A method for determining synchronization of uplink timing in a machine type communication (MTC) system comprising a machine type communication device (MTCD) and a network element is disclosed that takes advantage of the MTCD being at a fixed location relative to the network element. The method includes receiving at the MTCD an uplink timing adjustment value from the network element and storing the uplink timing adjustment value at the MTCD. The MTCD then uses the stored uplink timing adjustment value from a previous uplink transmission for synchronizing uplink timing for a subsequent uplink transmission from the MTCD to the network element even following a period of inactivity of the MTCD, or expiration of any existing maximum uplink timing alignment period permitted for use of the timing adjustment value by the MTCD, or MTCD clock drift.
