Methods and systems for data collection in an environment including pumps and fans are disclosed. A monitoring system may include a data collector communicatively coupled to a plurality of input channels, wherein the input channels are communicatively coupled to sensors measuring operational parameters of a pump or fan. A data storage may store one or more frequencies related to an operation of the pump or fan, and a data acquisition circuit may interpret a plurality of detection values from the collected data. A frequency evaluation circuit may detect a signal on one of the input channels at a frequency higher than the one or more frequencies at which the pump or fan operates.

Certain aspects of the present disclosure provide techniques for configuring hybrid automatic repeat request (HARQ) soft combining for a subset of HARQ processes supported by a user equipment (UE). A method performed by the UE generally includes transmitting capability information indicating a capability of the UE to perform hybrid automatic repeat request (HARQ) soft combining and receiving, based on the capability information, configuration information from the BS configuring the UE to perform soft combining on only a subset of a set of HARQ processes.

A transmitting device includes a first layer processor configured to include a buffer to store therein transmission data, the first layer processor configured to execute processing for a first layer on the transmission data, a second layer processor configured to execute processing for a second layer that differs from the first layer on the transmission data, and a transmitter configured to transmit the transmission data processed by the first layer processor and the second layer processor. The first layer processor discards the transmission data stored in the buffer in accordance with a parameter used for transmission control in the processing for the second layer.

A method for handling contention based data transmission (CBDT) in a wireless communication network is disclosed. The method includes: allocating CBDT resource blocks to a plurality of user equipment (UEs); receiving data bits and control bits on one or more resource blocks among the allocated CBDT resource blocks from a group of UEs among the plurality of UEs; determining whether each of the received data bits and control bits is decoded successfully; transmitting a negative acknowledgment message to each UE in the group of UEs based on determining that the received control bits are decoded successfully, and the received data-bits are not decoded successfully; and storing the data-bits which are not decoded successfully in a hybrid automatic repeat request (HARQ) buffer.

A method and device for retransmitting data are provided. The method includes: receiving, by a first device, on a DRB, a first PDCP PDU transmitted by a second device; performing, by the first device, on a PDCP layer, an IP verification for the first PDCP PDU; transmitting, by the first device, a PDCP status report to the second device when the IP verification for the first PDCP PDU is failed and a trigger condition is met, where the triggering condition is used for triggering the first device to transmit the PDCP status report to the second device. Thus, it can be ensured that the first PDCP PDU transmitted by the second device is received on the DRB again by the first device when the IP verification for the first PDCP PDU is failed, thereby effectively solving the problem of data packet loss caused by a failure of IP verification.

A wireless device receives a downlink control information indicating an assignment for a TB or release of a SPS configuration. The TB or the SPS configuration may be associated with a first priority or a second priority. The wireless device may transmit a feedback via an unlicensed cell. Transmitting the feedback may be based on a first value of an unlicensed parameter in response to the TB or the SPS configuration being associated with the first priority. Transmitting the feedback may be based on a second value of the unlicensed parameter in response to the TB or the SPS configuration being associated with the second priority.

Provided are a method by which a first device performs wireless communication an apparatus for supporting same. The method may comprise: receiving, from the base station through a physical downlink control channel (PDCCH), a downlink control information (DCI) related to the SL HARQ process ID, wherein the DCI includes information related to a second SL grant for retransmission of the MAC PDU and information related to a second PUCCH resource, wherein, based on the buffer related to the SL HARQ process ID being flushed, the first device does not transmit the MAC PDU to the second device based on the second SL grant, and the first device does not transmit SL HARQ feedback information related to the MAC PDU to the base station based on the second PUCCH resource.

Disclosed are: a communication technique for merging, with IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system; and a system therefor. The present disclosure can be applied to intelligent services (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, healthcare, digital education, retail, security- and safety-related services, and the like) on the basis of 5G communication technology and loT-related technology. The invention of the disclosure presents a method for effectively managing a HARQ process for satellite communication or V2X communication.

Presented are systems and methods for indicating whether a scheduled data transmission is a retransmission or a new transmission. A wireless communication device may receive a downlink control indicator (DCI) including a first indicator from a wireless communication node. The wireless communication node may transmit the DCI including the first indicator to a wireless communication device. The first indicator can be indicative of whether a scheduled data transmission is a retransmission.

The present invention relates to a method of transmitting a buffer status report (BSR) by a user equipment (UE) in a wireless communication system. Especially, the method includes the steps of receiving information on a logical channel from a network, wherein the information indicates that the logical channel is one of a first state or a second state; triggering the BSR when uplink (UL) data for the logical channel becomes available and when either none of other logical channels which are the indicated state contains any available UL data or the UL data belongs to the logical channel with higher priority than a priority of any logical channel containing available UL data and being the indicated state; and transmitting the BSR to the network.
