Patent number: 11683836Abstract: A method by a communication device for supporting a random access procedure in a wireless communication network. The communication device provides an indicator for indicating a presence of an initial access request by the communication device. The initial access request is part of the random access procedure. The indicator comprises a pre-defined synchronization sequence, wherein one of: the indicator comprises a first access burst extending over one time slot, wherein the first access burst comprises the pre-defined synchronization sequence, which is longer than 41 bits, and the indicator comprises a second access burst extending over two time slots, the second access burst comprising the pre-defined synchronization sequence, which is longer than 88 bits. The communication device transmits the indicator on a random access channel in uplink to a network node.

Publication number: 20220272719Abstract: A user equipment (UE) transmits an SR to a network node using a first transmission duration a particular number of times. The UE then determines a longer transmission duration for transmitting a further SR based on determining that no response has been received from the network node in response to any of the particular number of times the SR was transmitted.
