Network-side and device-side methods and apparatuses improve transmit link adaptation for devices operating in a cellular network that have interference-canceling receivers. Own-cell link adaptation towards a device in a current transmission interval exploits a determined mapping between the interfering-signal cancelation efficiency of the device versus the interfering-signal transport format, in combination with actual knowledge of the transport format that will be used to make an interfering neighbor-cell transmission in the current transmission interval. For example, a serving radio node uses the known transport format of the interfering transmission, to accurately determine the expected cancellation efficiency for the device with respect to the interfering transmission, and uses the expected cancellation efficiency to obtain a more accurate estimate of the own-cell channel quality expected for the device in the current transmission interval. Link adaptation towards the device in the current transmission interval uses this more accurate estimate of own-cell channel quality.

Embodiments of the present application disclose a slot format indication method and a related product. The method comprises: a network device transmits a slot format indicator (SFI) to a terminal, the SFI being used for indicating a slot format of at least one carrier, the at least one carrier comprising a first carrier, the slot format indicated by the SFI being determined on the basis of a first subcarrier spacing, and a subcarrier spacing of the first carrier being an integer multiple of the first subcarrier spacing. According to the embodiments of the present application, the slot format of one or more carriers can be indicated without relying on the subcarrier spacing of a particular carrier.

In a terminal, in a slot having allocated thereto both an uplink control channel (PUCCH) and an uplink channel (PUSCH) that includes uplink data, in a case where the difference between the power spectrum density (PSD) of the PUCCH and the PSD of the PUSCH is greater than a threshold value (permitted difference), a control unit drops symbols of the PUSCH in a transmission interval for the PUSCH overlapping with a transmission interval for the PUCCH. A transmission unit transmits at least the PUCCH in the slot.

In a base station (100), a division number calculating unit (103) calculates the division number of a PRB pair on the basis of a first number of REs capable of mapping an allocation control signal, a second number of REs capable of mapping signals other than the allocation control signal, and a reference value, which is the number of REs satisfying the reception quality request in a terminal (200) for the allocation control signal, in each PRB pair. Then, a control signal mapping control unit (104) determines a search space by determining a control channel element group constituting a plurality of mapping unit resource region candidates within a CCE group obtained by separating each PRB pair contained in a first group into the same number as the division number.
