Aspects of the subject disclosure may include, for example, obtaining channel cross correlation data relating to multiple user equipment (UEs) being served in a cell, wherein the channel cross correlation data comprises a correlation coefficient associated with a first UE of the multiple UEs and a second UE of the multiple UEs, identifying that the first UE is experiencing decreasing throughput, responsive to the identifying that the first UE is experiencing decreasing throughput, determining whether the correlation coefficient associated with the first UE and the second UE satisfies a correlation threshold, and, based on a first determination that the correlation coefficient does not satisfy the correlation threshold, adjusting a downlink (DL) transmit power allocation for transmissions directed to the first UE. Other embodiments are disclosed.

A data transmission method and device are provided. The method comprises a non-access stratum of a terminal device obtains description information of data to be transmitted; the non-access stratum determines, according to a mapping relationship between preset data description information and reliability transmission indication information, and the description information of the data to be transmitted, the reliability transmission indication information corresponding to the data to be transmitted, the reliability transmission indication information being used for indicating whether to perform reliability transmission on the data to be transmitted; transmitting, by the NAS, the reliable transmission indication information corresponding to the data to be transmitted to an access stratum of the terminal device, and performing, by the terminal device, transmission of the data to be transmitted.

A method to prioritize sidelink logical channel (SL LCH) during destination UE selection for sidelink Logical Channel Prioritization (LCP) procedure in NR sidelink communication is proposed to avoid resource starvation. A TX UE prioritizes an RX UE having at least one SL LCH that has not satisfied a required minimum bit rate during destination UE selection when allocating SL resource to a new MAC PDU for SL transmission. The TX UE maintains a value Bj for each SL LCH j, where Bj>0 indicates that the logical channel has not met the requirement of prioritized bit rate. If at least one destination UE has SL LCH with data available for transmission and with Bj>0, then the selected destination UE is the one has the highest-priority SL LCH with data available for transmission and with Bj>0.

Provided are an uplink transmission sending method and device, an uplink transmission receiving method and device, a terminal, a service node, and a medium. The method includes: determining a sending mechanism of an uplink transmission according to an uplink transmit mode in the case of multiple carriers; and sending the uplink transmission according to the sending mechanism.

Provided are an uplink transmission method and device, a communication node and a storage medium. The uplink transmission method includes: cancelling a transmission of part or all of time domain symbols in a first uplink transmission in a case where the first uplink transmission overlaps with a second uplink transmission in a time domain, where the first uplink transmission corresponds to a first priority, the second uplink transmission corresponds to a second priority, and the first priority is lower than the second priority; and transmitting a third uplink transmission through time domain symbols of which the transmission is cancelled in the first uplink transmission in a case where a set condition is satisfied.

An example method for wireless communication at a first user equipment (UE) may include receiving at least a first sidelink transmission from a second UE, wherein at least a second sidelink transmission from a third UE is scheduled contemporaneously with at least the first sidelink transmission from the second UE. The method may also include transmitting an indication in a transmission occasion to at least one of the second UE or the third UE based at least in part on a prioritization of information for the transmission occasion, wherein the indication indicates that at least the first sidelink transmission from the second UE is scheduled contemporaneously with at least the second sidelink transmission from at least the third UE.

Methods, systems, and devices for wireless communications are described. A receiving device (such as user equipment (UE)) may receive a downlink grant including an indication to report channel state information. The receiving device may identify, based on the downlink grant, a number of channel state information processing units associated with reporting the channel state information, and may determine that an available number of channel state information processing units is less than the number of channel state information processing units. In some cases, the receiving device may allocate, based on the determining, a set of channel state information processing units including the available number of channel state information processing units and one or more additional channel state information processing units. The receiving device may then transmit the channel state information report based on the set of channel state information processing units.
