摘要： Aspects of the disclosure relate to methods and apparatus for scheduling traffic between a transmitting device and a receiving device. A transmitting device negotiates with a receiving device to reserve a slot for communicating data with the receiving device and determines whether the transmitting device is a master or a slave with respect to the receiving device. If the transmitting device is the master, the transmitting device sends, at a beginning of the slot, a transmission priority (TxP) signal, wherein the TxP signal indicates that the transmitting device intends and has priority to transmit the data in the slot. The transmitting device then receives, from the receiving device, a clear-to-send (CTS) message in the slot based on the TxP signal, and transmits the data to the receiving device in the slot upon receiving the CTS message. Other aspects, embodiments, and features are also claimed and described.

摘要： Aspects of the disclosure relate to mechanisms for dynamic prioritization of uplink (UL) traffic at a user equipment (UE). In some examples, the UE may determine to delay transmission of UL traffic by skipping one or more UL transmission opportunities based on one or more factors, such as a power saving indication, a priority level of the UL traffic, a type of the UL traffic, a volume of the UL traffic, and/or current channel conditions. In some examples, the UE may be configured with a parameter controlling the ability of the UE to delay a transmission of UL traffic. In some examples, when the UE is operating in a semi-persistent scheduling mode and a power saving mode, such as a connected mode discontinuous reception (C-DRX) mode, the UE may dynamically interrupt an OFF duration of the C-DRX cycle to transmit UL traffic.

摘要： Aspects of the present disclosure relate to techniques for retransmission of code block groups when code block group (CBG) level feedback is unreliable. A user equipment (UE), in a first slot, transmits a first CBG feedback corresponding to a first set of CBGs received from a base station. In a second slot after the first slot, the UE receives downlink control information (DCI) and a first cyclic redundancy check (CRC). The first CRC is generated based on the DCI and further scrambled by a first concatenation of CBG feedbacks as decoded by the base station. The UE generates a second CRC based on the DCI and further scrambled by a second concatenation of CBG feedbacks including the first CBG feedback. The UE determines that the base station correctly decoded the first CBG feedback based on a comparison of the first CRC and the second CRC.

摘要： Aspects of the disclosure relate to communication systems, apparatus and methods which enable or support transmitting/receiving downlink control information (DCI) carrying a downlink grant or an uplink grant. A method includes detecting a reference length based on an effective length of a downlink (DL) grant DCI and an effective length of an uplink (UL) grant DCI and calculating a length difference based on the effective DL grant DCI length and the effective UL grant DCI length. A length of a padding field in the DL grant DCI and/or the UL grant DCI is set equal to the calculated length difference such that the lengths of the DL grant DCI and UL grant DCI are both equal to the reference length. Padding bits are inserted in the padding field of the DL grant DCI and/or the UL grant DCI. Thereafter, the DL grant DCI and/or the UL grant DCI is encoded and transmitted to a scheduled entity.

摘要： Aspects of the disclosure relate to a new radio (NR) single symbol design in which reference signals and data tones are frequency division multiplexed (FDM). In a particular aspect of the disclosure, a different encoding sequence is assigned to each possible value of an information element (IE) such that a minimum distance between encoding sequences corresponding to any pair of possible values is maximized. A symbol corresponding to a particular value of the IE is then transmitted. Here, the symbol is configured according to a sequence selected from a set of sequences corresponding to the particular value of the IE, such that the symbol comprises a plurality of reference signals FDM with a plurality of FDM resource elements.

摘要： Aspects of the disclosure relate to wireless communication systems configured to provide techniques for utilizing a one-symbol space-time block code (STBC) process to encode control information for transmission on an uplink control channel. The one-symbol STBC process produces two code blocks, each for transmission on a different antenna. Each code block may be time domain spread across multiple single-carrier frequency division multiple access (SC-FDMA) uplink control channel symbols using the same spreading code to enable recovery of the code blocks at the receiver.

摘要： Wireless communication devices, such as a scheduled entity, are adapted to facilitate uplink transmissions on multiple physical uplink control channels (PUCCHs) of a regular burst period. According to one example, a scheduled entity may obtain a payload for an uplink transmission on a PUCCH. The scheduled entity may subsequently send the uplink transmission utilizing two or more physical uplink control channels (PUCCH) of a regular burst period, where each PUCCH is associated with a different frequency band of the regular burst period. According to one example, a scheduling entity may receive an uplink transmission, where the uplink transmission utilizes a first PUCCH of a regular burst period, and at least a second PUCCH of the regular burst period, each of the first and second PUCCHs being associated with respectively different frequency bands of the regular burst period. Other aspects, embodiments, and features are also included.
