Abstract: A wireless device (12, 50) obtains a window of time for bundling of a set of uplink transmissions (20) on a carrier or bandwidth part. The wireless device determines whether or not to apply a timing advance adjustment (16) within the window of time. The timing advance adjustment comprises an adjustment to a transmission timing of an uplink transmission on the carrier or bandwidth part. The wireless device transmits the uplink transmission on the carrier or bandwidth part during the window of time using a transmission timing which is in accordance with the determining. The determining is based on whether the timing advance adjustment is indicated by a received timing advance command (18) or whether the timing advance adjustment is due to a detected error in downlink timing.

Abstract: 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.

Abstract: Systems and methods are disclosed for frequency hopping schemes that are compatible with joint channel estimation. In one embodiment, a method implemented in a User Equipment (UE) comprises determining a value of a hopping index for a first set of N consecutive slots, wherein the N is an integer greater than 1, and after the N consecutive slots, incrementing the value of the hopping index for a second set of N consecutive slots. The method further comprises, for an uplink slot within the second set of N consecutive slots, determining a set of physical resource blocks (PRBs) in which to transmit a physical channel from a set of frequency offsets according to the value of the hopping index for the second set of slots and transmitting the physical uplink channel in the selected set of PRBs in the uplink slot.
