    Patent number: 11671949
    Abstract: The embodiments herein relate to time domain resource allocation for PUSCH transmission. In one embodiment, there proposes a method in a wireless communication device for Random Access (RA), comprising: transmitting a preamble on Physical Random Access Channel (PRACH); receiving a Random Access Response (RAR) message; transmitting, on Physical Uplink Shared Channel (PUSCH), a message for terminal identification (Msg3), wherein the time resource allocation of Msg3 is different than the time resource allocation of other message to be transmitted on the PUSCH (normal PUSCH). The embodiments herein can support flexible time resource allocation configuration for Msg3, and at the same time, the signaling overhead in RAR/DCI for indicating the time resource allocation of PUSCH carrying Msg3 can be reduced.

  • Methods and arrangements in a telecommunications network
    Patent number: 11659511
    Abstract: The present invention relates to methods and arrangements in a base station and a user equipment for determining an uplink transmission timing correction for communication in a telecommunication system in which aggregation of component carriers is applied. The base station receives a signal from the user equipment on an uplink (UL) component carrier and measures the arrival time of the signal. A timing correction of the UL transmission timing based on the arrival time of the signal is determined. Thereupon the base station determines for which of the uplink component carriers used by the user equipment the timing correction is valid. The timing correction and the validity information is sent to the user equipment. The user equipment adjusts the UL transmission timing for each UL component carrier the timing correction is valid for.
