A communication method and apparatus the method including generating indication information, and sending the indication information to a terminal, wherein the indication information indicates to the terminal to activate a first frequency domain resource pair comprising an uplink frequency domain resource and a downlink frequency domain resource, wherein the uplink frequency domain resource is associated with the downlink frequency domain resource, wherein the uplink frequency domain resource and the downlink frequency domain resource have a same center frequency, wherein the uplink frequency domain resource and the downlink frequency domain resource are bandwidth parts on a carrier, wherein the bandwidth parts each have a bandwidth that is smaller than a bandwidth of the carrier, and wherein the first frequency domain resource pair is in a deactivated state when the indication information is sent.

A method for operating user equipment (UE) includes generating, by the UE, a transmit precoding matrix indicator (TPMI) list including one or more TPMIs selected from a set of available TPMIs stored at a base station (BS). Data indicative of the TPMI list is transmitted to the BS. An index of the TPMI list is transmitted to the BS. Downlink control information (DCI) is received from the BS including an indication of at least one TPMI from the TPMI list based on the index. Uplink data is transmitted to the BS on a physical uplink shared channel (PUSCH) using the at least one TPMI.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling which indicates a resource block indicating a number of reference signal tones and data tones in an uplink transmission. In some cases, the UE may determine a first transmission power for the reference signal tones, and a second transmission power for the data tones that is different from the first transmission power. In some other cases, the UE may identify a frequency allocation for the resource block which allocates a same frequency bandwidth for the reference signal tones and the data tones, and the UE may determine a same transmission power for the reference signal tones and the data tones based on the frequency allocation. Based on the determination of transmission powers, the UE may transmit the reference signal tones and the data tones to a base station.

This disclosure provides a portable object detection system and method. The system includes a first cluster network, a family cluster network, and a detection server. The first cluster network includes a portable object coupled with a small communication device (SCD), a first cluster head device (first CHD) including a smartphone that registers the SCD prior to monitoring, and performs mutual monitoring between the SCD and the first CHD. The detection server manages the first CHD and a second CHD, and when the detection server receives a loss event from the first CHD in the first cluster network, it requests a mutual search by the second CHD for the SCD as a lost target in the first cluster network.

The mutual monitoring in a first cluster network adjusts a message transmission interval and a radio transmission power depending on collected parameters such as the SCD's location information, mobility, power capacity, and others.

System and method for improving channel efficiency in a wireless link between an access-point transceiver and a first transceiver. The first transceiver may have a first data throughput rate that is lower than the maximum possible data throughput rate of the wireless link. The first transceiver may include a first receive buffer. An indication of the first data throughput rate and a size of the first receive buffer may be received and stored by the access-point transceiver. A first size of a first data packet for transmission to the first transceiver may be determined by the access-point transceiver based on one or more of the first data throughput rate and/or the size of the first receive buffer. The first data packet of the first size may be transmitted to the first transceiver by the access-point transceiver at a data rate that is higher than the first data throughput rate.
