    Abstract: Embodiments are provided for adaptive user equipment (UE) cooperation mode selection in wireless networks. An adaptive UE cooperation strategy is implemented, which adaptively switches between a Decode-and-Forward (D&F) mode and a soft UE combining mode that involves combining, at the TUE, signals from multiple cooperating UEs (CUEs). A method by a network component includes obtaining access link qualities for links between a base station and a plurality of CUEs for a target UE (TUE). A UE cooperation mode or a hybrid UE cooperation mode is then selected from a plurality of supported UE cooperation modes according to the access link qualities of the CUEs. At least one of the CUEs is then instructed to cooperate in forwarding the signals to the TUE using the selected UE cooperation mode. The CUEs can dynamically opt out of the UE cooperation according to the channel quality of the CUEs or TUE.

    Abstract: Methods and systems for a frame structure for machine-type communications (MTC) with adjustable pulse bandwidth are described. In an embodiment, the frame structure is an uplink frame structure that illustrates a representation of a plurality of coverage levels. The coverage levels are associated with a coverage range of a base station. Each coverage level is associated with corresponding sub-frames, and each sub-frame within a coverage level has the same sub-frame length and bandwidth.

    Abstract: Methods and systems are provided in which a UE transmits sidelink (SL) control information comprising a scheduling assignment (SA) indicating an SL transmission resource for a SL data transmission to a target UE. The SL transmission resource is based on one or more occupied SL resources identified by the UE and the SL transmission resource includes resources for an initial transmission and one or more retransmissions. The UE then transmits the SL data transmission using the SL transmission resource according to the transmitted SL control information. This is done without receiving, in a downlink control information (DCI), a grant of communication resources.

    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.

A method involves obtaining, by a receive user equipment (UE), configuration information relating to a sidelink transmission between the first UE and a second UE, the configuration information for indicating to the first UE that the sidelink transmission is not associated with any corresponding sidelink control information (SCI). A further step involves receiving, by the receive UE, the sidelink transmission from the second UE using time and frequency resources indicated by the configuration information. Another method involves obtaining, by a transmit UE, configuration information relating to a sidelink transmission between the first UE and a second UE, the configuration information for indicating to the first UE that the sidelink transmission is not associated with any corresponding SCI and transmitting, by the first UE, the sidelink transmission to the second UE using time and frequency resources indicated by the configuration information.
