(57) A communication device operating in a communications network can determine to transmit information using repetition to a network node operating in the communications network during a random access, RA, procedure. The communication device can further determine a subset of preambles based on determining to transmit the information using repetition. Responsive to determining the subset of preambles, the communication device can determine a preamble of the subset of preambles to transmit to the network node to indicate a type of the repetition. The communication device can further transmit the preamble to the network node. The communication device can further transmit the information using the type of repetition to the network node.

(57) A booster explosive (10) comprises a canister body 12 within which is a cap well (20) having disposed therein a detonator (24). A protective sleeve (28) encloses the cap well (20) except for that portion of the cap well, the active portion (20d), which encloses the explosive end section (24a) of detonator (24). The protective sleeve serves to attenuate the force of shock waves from nearby prior explosions acting on the detonator (24). An annular air space (32) may be provided between protective sleeve (28) and cap well (20) to further attenuate the force of such shock waves. Attenuation of the shock waves reduces the likelihood of damage to detonators (24) by prior nearby explosions.
