The embodiment of the invention discloses an overheating indication method and related equipment. The overheating indication method provided by the embodiment of the invention comprises the followingsteps: when terminal equipment is in an overheating state, the terminal equipment sends first overheating indication information to network equipment; the terminal device receives first reconfiguration information sent by the network device, wherein the first reconfiguration information is generated by the network device according to the first overheating indication information; and the terminal device does not support the uplink reference signal antenna in-turn transmission capability according to the first reconfiguration information.

Embodiments of the present invention provide a method and an apparatus for transmitting broadcast-multicast single-frequency network measurement data, where second measurement data is acquired by preprocessing acquired first measurement data, and the second measurement data is sent to a base station. Because the second measurement data is obtained after the first measurement data is preprocessed, a size of the second measurement data is smaller than that of the first measurement data, thereby reducing a transmission overhead.

According to certain embodiments, methods and systems for toggling transmission parameters in a heterogeneous network to achieve a target block error rate by a network node may include obtaining a signal-to-noise ratio (SINR) estimate from channel quality information for a downlink between a network node and a wireless device. For each of a first code word and a second code word to be transmitted on the downlink, a block error rate estimate may be obtained based on the SINR estimate. The network node may then determine at least one expected SINR for the first code word and the second code word. The at least one expected SINR may be determined as a function of the SINR estimate and the block error rate estimate. Based on the at least one expected SINR for the first code word and the second code word, a modulation and coding scheme (MCS) for obtaining a target block error rate may be selected. The network node may then transmit the first code word on a first transmission layer and the second code word on a second transmission layer during a first transmission time interval. In a second transmission time interval, the network node may transmit the first code word on the second transmission layer and the second code word on the first transmission layer.
