Abstract: A method may include receiving, by a user equipment from a network entity, a first downlink (DL) control signal activating semi-persistent scheduling (SPS) of a first set of downlink data transmissions, the downlink control signal indicating an applicable hybrid automatic repeat request (HARQ) feedback timing for the first set of downlink data transmissions and receiving one or more of the first set of downlink data transmissions. The user equipment may determine that an applicable HARQ feedback timing for a second set of downlink data transmission previously received with an inapplicable HARQ feedback timing has not been provided. In response to the determination, the user equipment may determine a HARQ feedback timing for the one or more of the first set of downlink data transmissions based a second DL control signal indicating an applicable HARQ feedback timing received after reception of the one or more of the first set of downlink data transmissions.

Abstract: Systems, methods, apparatuses, and computer program products for the transmission of uplink (UL) control information via unlicensed spectrum are provided. One method includes dynamically allocating, by a network node, control channel resources for transmitting of uplink control information (UCI). The method may also include scheduling a user equipment with multiple transmission opportunities for each hybrid automatic repeat request (HARQ) acknowledgement/non-acknowledgement (A/N) on the control channel in multiple uplink subframes.

Abstract: A method for grouping of CS (and comb values) for DM-RS and SRS on shared time-frequency resources is described. The method includes dividing a RS space into at least a first region and a second region. The method also includes allocating, from the first region, a DM-RS sequence CS and/or a DM-RS comb for a DM-RS; and allocating, from the second region, a SRS sequence CS and/or a SRS comb for a SRS. The DM-RS and the SRS are on the same resources on an uplink shared channel (such as a PUSCH for example). The RS space comprises at least one of a CS set and a IFDM comb set. The CS set and/or the IFDM comb set of the first region is based at least in part on a number of physical resource blocks allocated to the uplink shared channel. Apparatus and computer readable media are also described.

Abstract: Embodiments of the present disclosure relate to bit reduction in resource information. According to embodiments of the present disclosure, the number of bits to indicate the resource allocation is reduced and the network device generate the control information based on an offset associated with the bit reduction. In this way, multiple transmission opportunities for the transmission of Msg3 of the random access procedure are provided without increasing the signaling overhead.
