Abstract: There is described a multiple subscriber identity arrangement having a modem capable of receiving messages related to either one of at least two subscriber identities, but not simultaneously. The arrangement further comprises a control unit configured to, when the modem performs communication activity associated with a first subscriber identity: determine whether gaps not allocated for the communication activity associated with the first subscriber identity coincide with paging occasions associated with a second subscriber identity; and, if at least one gap not allocated for the communication activity associated with the first subscriber identity coincides with at least one paging occasion associated with the second subscriber identity, cause the modem to switch to the second subscriber identity to read one paging message on a paging channel associated with the second subscriber identity.

Abstract: An interference cancellation technique is implemented in a receiver adapted for determining an estimation of interferences when receiving an OFDM signal made of packets. Each packet includes a first training field, a second training field, a first header field, a second header field and a data field. The receiver detects a first symbol value of the first header field, and a second symbol value of the second header field, the first and the second header fields having been modulated using different modulation schemes. The estimation of interferences is determined using the first and the second symbol values.

Abstract: A Reference Signal Received Power (RSRP) value is produced from a received Orthogonal Frequency Division Multiplexed (OFDM) signal that comprises a plurality of reference symbols located at known sub-carrier frequencies and times within the received OFDM signal. RSRP value production involves, for each hypothesized error state selected from a plurality of different hypothesized error states, ascertaining a corresponding hypothesized RSRP value, and then using the hypothesized RSRP values as a basis for determining a value for use as the produced RSRP value (e.g., by selecting a maximum one of the hypothesized RSRP values as the produced RSRP value). In this technology, each of the hypothesized error states is a hypothesized frequency error paired with a hypothesized timing error and the corresponding hypothesized RSRP value is produced by adjusting one or more measured channel estimates as a function of the hypothesized error state.
