摘要： Systems and methods of the present disclosure are directed to a method performed by a wireless communication device. The method includes receiving a configuration of a plurality of TCI states via RRC signaling. The method includes receiving a MAC CE that activates a subset of the plurality of TCI states. The method includes receiving a DCI that indicates one or more of the subset of the plurality of TCI states to be used and explicitly or implicitly indicates one or more particular CORESETs for which the one or more of the subset of the plurality of TCI states are to be used. The method includes using one or more spatial QCL downlink reference signals contained in the one or more of the subset of the plurality of TCI states to receive a PDCCH corresponding to the one or more particular CORESETs.

摘要： 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.

摘要： A method, network node and wireless device, WD, providing signaling mechanisms for enabling repetitions of messages related to random access, RA, are disclosed. According to one aspect, a network node transmits an indication of a number of zero or more repetitions of a message related to RA to be transmitted by the WD in response to a random access response, RAR, message transmitted to the WD. The network node further receives at least one message related to RA.

摘要： Systems and methods are disclosed herein that relate to multi-Transmission/Reception Point (TRP) uplink transmission in a cellular communications system. In one embodiment, a method performed by a wireless communication device comprises receiving, from a network node, a configuration of two Sounding Reference Signal (SRS) resource sets, a first and second SRS resource sets, each comprising one or more SRS resources. The method further comprises receiving, from the network node, downlink control information (DCI) that schedules a physical uplink channel transmission comprising a first part associated to a first SRS resource in the first SRS resource set and a second part associated to a second SRS resource in the second SRS resource set, wherein the first and second SRS resources are indicated in the DCI. The method further comprises transmitting the physical uplink channel transmission in accordance with the DCI.

摘要： A system and method for providing time domain allocations in a communication system. In an embodiment, an apparatus operable in a communication system and including processing circuitry is configured to receive an indication of a time domain allocation in downlink control information associated with a radio network temporary identifier (“RNTI”) identifying the apparatus, and employ the time domain allocation associated with the RNTI for transmissions associated with the apparatus. In another embodiment, an apparatus operable in a communication system and including processing circuitry is configured to associate a time domain allocation with a RNTI identifying a user equipment, and provide an indication of the time domain allocation in downlink control information to allow the user equipment to employ the time domain allocation associated with the RNTI for transmissions associated therewith.

摘要： A method of scheduling Msg3 configuration by a network node may be provided. Information may be generated indicating transmission duration, DMRS configuration, and/or starting position for Msg3 sending by a user equipment, UE. Transmission of signaling of the information to the UE may be initiated for scheduling Msg3 transmission by the UE. A method of scheduling by the UE includes receiving information from the network node indicating transmission duration, DMRS configuration, and/or starting position for Msg3 transmission. The UE transmits Msg3 based on a schedule determined based on the information.
