Abstract: The present application discloses a method and an apparatus for transmitting uplink control information (UCI), to resolve the issue of repeated transmissions of UCI in the prior art. In an embodiment of the present application, a terminal determines a bit sequence of coded UCI of a first transmission, the UCI being repeatedly transmitted on a PUCCH, and the terminal transmits the bit sequence of the coded UCI in a determined uplink channel in each subsequent retransmission of the UCI. A network side apparatus uses the same method to determine a bit sequence of coded UCI of a first transmission, and receives, via a determined uplink channel, a repeatedly transmitted bit sequence of the coded UCI. In the embodiments of the present application, a bit sequence of coded UCI is determined according to a channel of the UCI in a first transmission time slot.

Abstract: Bandwidth part (BWP) switching may benefit a wireless communications system. Such BWP switching may include indication of one or more timing parameters used for time domain resource allocation. For example, the timing parameters may be indicated based on an index to a look-up table (e.g., a bit field in a control transmission). In some cases, one or more tables may be configured for a given BWP, and different tables may contain a different number of rows. The size of the bit field indexing the table may in turn depend on the number of rows. When switching from a first BWP to a second BWP, the size of the bit field may be based on the table of the first BWP, but the bit field may index the table of the second BWP. Techniques supporting improved timing parameter management during BWP switching are discussed herein.

Abstract: A communication technique for synchronizing a set of radio nodes is described. In this communication technique, the radio node arbitrates (e.g., using a precision time protocol or PTP) with the other radio nodes based on a selection technique to select a synchronization master in the set of radio nodes. This synchronization master may be selected to have a predefined performance based on a type of communication environment of the set of radio nodes. For example, the type of communication environment may include overlap between at least one of the radio nodes in the set of radio nodes and a macrocell in a cellular-telephone network, or may exclude overlap between the set of radio nodes and the macrocell. Moreover, the synchronization master may specify time, frequency, and phase synchronization for the set of radio nodes. Thus, when the synchronization master is different from the radio node, the radio node synchronizes with the synchronization master.

Execution of the instructions further cause the apparatus to obtain, from a user equipment (UE) at a PUR start time, a first message on a PUR associated with the PUR configuration information, the PUR start time associated with the H-SFN corresponding to the LSB.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may communicate with a network device in an idle or disconnected state using preconfigured uplink resources (PURs). The UE may transmit uplink data, and may begin to monitor for a PUR response message corresponding to the uplink data after a configurable time offset. The Base station may indicate the configurable time offset in an RRC release message, another message, or the UE may select the configurable time offset from a set of configurable time offsets based on one or more system parameter values. Additionally, the UE may not monitor for PUR response messages after every PUR occasion during which it transmits uplink data.
