  • Publication number: 20200178284
    Abstract: This disclosure provides techniques for reducing waste of user equipment (UE) resources caused in transmission of a Physical Uplink Shared Channel (PUSCH) when a UE conducts searching for downlink control information (DCI) outside of a PUSCH transmission. This disclosure defines a first search space on the basis of an existing second search space that was used to receive DCI information to schedule a PUSCH. The first search space can be used to obtain a DCI having an ACK feedback. This disclosure provides systems and methods for determining the location of the first search space to receive a second DCI having ACK feedback during a PUSCH repetitive transmission and whether the second search space should be used for the second DCI instead. Outside of the PUSCH transmission, the UE receives DCI in the second search space, decreasing the unnecessary searching of DCI and increasing network efficiency.

  • Publication number: 20200068612
    Abstract: A method for providing scheduling request resources to a user equipment involves a wireless network node (e.g., an eNB) transmitting a configuration of scheduling request resources to the user equipment via radio resource control signaling, and the wireless network node enabling the scheduling request resources by transmitting a message to the user equipment via physical layer signaling. The message that enables the scheduling request resources may be transmitted as part of an uplink grant or downlink grant. In some implementations, the enabling message maps to one of several sets of scheduling request resources, which the wireless network node has previously communicated to the user equipment via radio resource control signaling. In other implementations, the selection of which set of scheduling request resources is to be enabling is made by the user equipment based on implicit signaling from the wireless node.
