摘要： Configurations for configured grant (CG) in new radio unlicensed (NR-U) systems is disclosed. CG configurations may, based on a periodicity, be provided either using a bitmap, shorter periodicity, or resource indicator value (RIV) signaling of start/end symbols, longer periodicity. Such CG configurations configure M sets of time division resource allocations. CG configuration may include common start/end symbols from for all contiguous allocations in one configuration. Common LBT starting points may be defined for all configured slots as indicated through a bitmap. The CG configuration allows for mini- and full slot configurations, in which the mini-slots are configured within the already configured CG slots. Repetition configurations include a type 1 for coverage and a type 2 for faster retransmission and reduced downlink feedback information (DFI) overhead. With multiple UEs, a UE identifier is added to the uplink control information (UCI). UEs may further ramp up power in the absence of DFI.

摘要： Methods, systems, and devices for wireless communications are described. A wireless communications system may support grants for uplink or downlink transmission over multiple transmission time intervals (TTIs). A multi-TTI grant may include a base grant and an extended grant that include separate information and may be transmitted simultaneously (e.g., within the same TTI) or separately. A grant type (e.g., whether a grant is a base grant or an extended grant) or an association between a base grant and an extended grant may be conveyed (e.g., via the multi-TTI grant). A downlink assignment index (DAI) may be included for one or more TTIs subject to the multi-TTI. For instance, DAI may be included for each TTI or for a subset of TTIs.

摘要： Aspects described herein relate to configuring communications over an acquired channel, where the configuration may indicate a set of resources used for communicating in at least one direction over the acquired channel. The set of resources may be based on a set of possible starting points within a slot for transmitting the communications.

摘要： Certain aspects of the present disclosure provide techniques for enhanced physical uplink control channel (PUCCH) transmission. In some cases, a UE obtains payload bits to be conveyed in a physical uplink control channel (PUCCH) transmission via an interlace of resource blocks (RBs), determines a group of the RBs available to the UE, and transmits the payload bits using the determined group of RBs, wherein the transmitting involves modulating different RBs of the group by at least one of different payload bits or sequences.

摘要： A user equipment (UE) may employ an extended cyclic prefix, a postfix, or both for sounding reference signal (SRS) transmissions, such that gaps between SRS transmissions are long enough for UE antenna switching operations, but shorter in duration than any maximum channel vacancy time durations set by a wireless communications system. Further, UEs may transmit SRSs to base stations in accordance with an SRS configuration. For example, a base station may provide SRS configuration information to a UE that indicates, for example, information related to SRS scheduling, subband information, a cyclic prefix length, a cyclic postfix length, listen-before-talk (LBT) type information, an SRS trigger, an SRS cancellation procedure, or any combinations thereof. Based on such SRS configuration information, a UE may perform partial subband SRS techniques, subband selection techniques, SRS bandwidth adaptation techniques, LBT type configuration techniques, etc.

摘要： Wireless communications systems and methods related to uplink (UL) communications in a wireless network are provided. In one embodiment, a first wireless communication device receives a transmission grant indicating a transmission period. The first wireless communication device selects a starting location for transmitting a communication signal from among a plurality of starting locations within the transmission period. The first wireless communication device transmits the communication signal during the transmission period based on the selected starting location. In one embodiment, a first wireless communication device transmits, to a second wireless communication device, a transmission grant indicating a transmission period. The first wireless communication device monitors for a communication signal from the second wireless communication device in the transmission period. The first wireless communication device identifies, upon detection of the communication signal, a starting location of the communication signal from among a plurality of starting locations within the transmission period.

摘要： Wireless communications systems and methods related to communications in a network that supports usage of configured grant uplink control information (CG-UCI) data are provided. A user equipment (UE) may receive a configuration for a configured grant resource and transmit an UL communication signal in the configured grant resource. The UL communication signal may include a CG-UCI multiplexed with UL data. Additionally, the CG-UCI may indicate whether the UL data includes additional UCI.

摘要： Wireless communications systems and methods related to communications in a network are provided. A user equipment (UE) may generate during a first time period, an uplink (UL) communication signal based on a scheduled grant or a configured UL grant. The UE may detect a downlink (DL) communication from a base station (BS) during a second time period after the first time period. The DL communication is devoid of the scheduled grant and the configured UL grant. The UE may transmit to the BS, the UL communication signal based on the scheduled grant or the configured UL grant in response to detecting the DL communication.

摘要： Techniques for dynamically controlling long physical uplink control channel (PUCCH) transmission are described. In an aspect, the disclosure describes a method for receiving a grant to transmit a long PUCCH, determining a grant type of the grant, wherein the grant type is one of a periodic grant or an aperiodic grant, determining a slot type of the slot to transmit the long PUCCH, and transmitting the long PUCCH over one or more slots based on the grant, the determined slot type, and the determined grant type. In another aspect, the disclosure describes a method for generating a triggering signal to transmit to a user equipment (UE), the triggering signal indicating to the UE to transmit a PUCCH, transmitting the triggering signal to the UE, and receiving the long PUCCH in response to the triggering signal.
