Abstract: Method and apparatus for transmitting downlink control information (DCI) are provided. The method includes: scheduling traffic channels in multiple transmission time intervals (TTIs) through a single DCI, where a subcarrier spacing of a carrier where the scheduled traffic channel is located is not smaller than a subcarrier spacing of a carrier where the DCI scheduling the traffic channel is located; and transmitting the DCI. A problem of how to use a multi-TTI scheduling for a cross-carrier scheduling in which a subcarrier spacing of a scheduling carrier is smaller than a subcarrier spacing of a scheduled carrier in the related art may be solved, and the effects of scheduling the multiple TTIs through a single DCI and reducing the overhead are achieved.

Abstract: The present disclosure describes methods, system, and devices for configuring and transmitting a physical random access channel (PRACH) transmission, particularly in a random access channel occasion (RO) for a uplink (UL) subband. A method includes performing, by a user equipment (UE), a PRACH transmission to a base station by: obtaining, by the UE, a RO configuration for a RO; determining, by the UE, whether the RO is valid for a UL subband based on a set of pre-defined rules, wherein the UL subband comprises at least one downlink (DL) symbol or at least one flexible symbol and occupies a part of frequency domain resources of the at least one DL symbol or at least one flexible symbol; and in response to the determining that the RO is valid, transmitting, by the UE, the PRACH transmission in the RO to the base station.

Abstract: This disclosure is generally directed to wireless communication systems and methods and relates particularly to resource configuration and allocation for time-division duplex. The various implementations described in detail below concern scheduling and allocation of time-frequency communication resources within a uplink subband configured within a set of resources that are otherwise configured for downlink transmission or for transmission with a flexible direction. Various embodiments are described below for dynamically scheduling downlink transmissions within the resources of the uplink subband, for modifying/extending resources for the uplink subband in order to improve uplink and downlink transmission resource balance in real-time. The disclosure below further provides various implementations for resolving uplink and downlink transmission time conflict within the uplink subband and for transmitting downlink reference signal over the UL subband.
