Abstract: Controlling access by a User Equipment (UE) to a cellular network may be effected by: receiving an instruction at the UE from a base station of the cellular network regarding transmission by the UE over a Random Access Channel (RACH) of the cellular network; and controlling when transmissions are made from the UE over the RACH, on the basis of the received instruction. In some cases, a transmission over the RACH may be made in response to the received instruction, which gives permission for the UE to transmit if it has data to send. In other cases, the instruction specifies a Group Identifier, which is compared with a Group Identifier specific to the UE and transmission over the RACH may be avoided based on the comparison. In particular, the UE may be a Machine Type Communication device.

Abstract: A memory tracking circuit activates a reset signal that resets a word-line pulse generator to switch the memory from an access state to a recess state. Activation is based on (i) a signal received at the far end of a tracking row after a propagation delay and (ii) a signal applied to a transistor-based gate delay. If the memory is in a fast PVT condition such that the gate delay is of less duration than, or substantially equal to, the propagation delay, then a slow-down circuit delays activation of the reset signal to allow sufficient access margin. The delay in the latter case is less than that in the former case. If the memory is in a slow PVT condition such that the gate delay is longer than the propagation delay, then the slow-down circuit does not delay activation of the reset signal to prevent excess access margin.

Abstract: A portable electronic device that has a radio frequency communication subsystem operationally connected switch-mode power supply subsystem. The switch-mode power supply subsystem generates a pulse-width modulation electrical signal that produces electromagnetic interference. The switch-mode power supply subsystem can reduce the slew rate of the pulse-width modulation electrical signal when the radio-frequency communication subsystem is active. This reduces the level of the electromagnetic interference signal only during radio frequency communication, which improves the efficiency of the radio frequency communication. Not having the reduced slew rate when there is no radio frequency communication allows for higher modulation efficiency.
