Abstract: Systems, methods, and instrumentalities are disclosed for narrowband (NB) LTE operation. A WTRU may receive a first downlink data transmission, for example, via a physical downlink shared channel (PDSCH). The WTRU may determine to send a hybrid automatic repeat request (HARQ) acknowledgment (ACK) in response to receipt of the first downlink data transmission. The WTRU may transmit a first uplink reference signal. The WTRU may indicate the HARQ-ACK using a first cyclic shift index that is applied to the first uplink reference signal. The WTRU may determine to send a HARQ negative ACK (HARQ-NACK), for example, on a condition that a second downlink data transmission is not correctly received. The WTRU may send a second uplink reference signal. The WTRU may indicate the HARQ-NACK using a second cyclic shift that is applied to the second uplink reference signal.

Abstract: Methods, systems, and devices for wireless communications are described. A station (STA) may receive a null data packet (NDP) on a plurality of subcarriers, and the STA may generate a channel state information (CSI) matrix for each subcarrier of the plurality of subcarriers. After generating a CSI matrix for a subcarrier, such as at least one subcarrier, the STA may scale each value in the CSI matrix using a power-of-two value to minimize complexity. Specifically, instead of scaling each value in the CSI matrix to a value between zero and one using divisions (for example, which may be computationally expensive), the STA may use shifting to scale each value in the CSI matrix. The STA may then quantize the scaled values in the CSI matrix for reporting, and the STA may transmit the quantized, scaled values in the CSI matrix in a CSI report.

Abstract: A wireless transmit/receive unit (WTRU) determines PDCCH candidates. For a slot, the WTRU determines a number of valid PDCCH candidates associated with at least one search space based on a number of designated search spaces associated with the WTRU in the slot, a type of the search space, a priority associated with the search space, a number of required CCE channel estimates associated with the search space, a maximum number of PDCCH candidates in a slot, and a number of control resource sets (CORESETs) associated with the slot. The WTRU may then attempt to decode CCEs in the at least one search space to recover a PDCCH associated with the WTRU. The WTRU may drop PDCCH candidates from the search space when the number of PDCCH exceeds a maximum value.

Abstract: An object of the present invention is to enable flexible design depending on use cases and to further improve the transmission efficiency of the entire system. A communication device includes: an acquisition unit configured to acquire first control information and second control information relating to a plurality of resources specified by a frequency and time available for data transmission; and a control unit configured to perform control in such a manner that data is transmitted to a transmission target after a resource is arbitrarily selected from the plurality of resources on the basis of the first control information, in which the control unit controls selection of the resource from among the plurality of resources on a basis of the second control information.
Abstract: A method and apparatus are disclosed. In an example from the perspective of a base station operating with Semi-Persistent Scheduling (SPS) for unicast and multicast, the base station configures a User Equipment (UE) with a unicast SPS operation configuration using a first information element including a sps-Config information element or a sps-ConfigToAddModList information element. The base station determines, based upon whether the first information element includes the sps-Config information element or the sps-ConfigToAddModList information element, whether or not to configure the UE with a multicast SPS operation configuration using a sps-ConfigMulticastToAddModList information element.
Abstract: Currently in 5G and 6G, user devices are required to search a large number of possible combinations of frequencies, start times, message lengths, and error-codes to find their downlink control messages. Disclosed is a faster and much simpler method for user devices to determine which downlink messages are intended for which user device, and also to determine the beginning and ending of each message within a stream of arriving data. The base station can affix a predetermined demarcation bit-sequence to the beginning of each message, and a different demarcation to the ending of the message. As an option, the demarcations may also serve as a demodulation reference, including predetermined amplitudes of the modulation scheme, immediately proximate to the message. Downlink demarcations may also include a characteristic feature, such as a gap of no transmission, for easy recognition and for evaluating noise.
Abstract: In connection with an RF communication system, exemplary aspects involve a method for use in a communication system in which a first system (e.g., 802.11) that is asynchronously based and which is susceptible to interference from a second system (e.g., synchronous-based LTE-CV2X). Such interference is due to the frequency spectrum used by the first and second systems overlapping. To mitigate interference issues, example methods spreads out the times for messages in the first system, based on information concerning occupancy of the channel, and transmitting them relative to the end of a cycled transmission allocated for use by the second system.

Abstract: A method for transmitting a physical uplink shred channel (PUSCH) by a terminal in a wireless communication system according to an embodiment of the present specification comprises the steps of: receiving downlink control information (DCI) scheduling a physical uplink shared channel (PUSCH); and transmitting the physical uplink shared channel (PUSCH) on the basis of the DCI. The format of the DCI is DCI format 0_0. On the basis that spatial relation RS information for transmission of the physical uplink shared channel (PUSCH) is not configured, the physical uplink shared channel (PUSCH) is transmitted on the basis of spatial relation quasi-colocation (QCL) RS information of a predefined control resource set (CORESET).
Abstract: In a message modulated according to orthogonal amplitude-modulated component signals in 5G or 6G, the receiver can attempt to recover a corrupted message by evaluating the modulation quality of each component signal in each message element. The modulation quality of each component signal may be determined according to a distance between the amplitude of the component signal and the closest amplitude level of the modulation scheme, as determined by a prior demodulation reference. The modulation quality may also be determined by the SNR and amplitude stability of the component signal. Upon detecting a corrupted message, the receiver can identify the faulted message elements according to modulation quality, and if the faulted message elements are clustered in a portion of the message (as is common), the receiver can request that just the faulted portion be retransmitted, saving time and bandwidth.
