摘要： Methods for enhancing Physical Uplink Shared Channel (PUSCH) reliability. In embodiments disclosed herein, a base station provides, and a wireless device receives, an instruction for transmitting a plurality of PUSCH repetitions based on two Sounding Reference Signal (SRS) resource sets. Accordingly, the wireless device transmits, and the base station receives, the plurality of PUSCH repetitions based on the instruction. In a non-limiting example, the wireless device can be configured to transmit the multiple PUSCH repetitions in accordance with codebook based PUSCH transmission or non-codebook based PUSCH transmission. As a result, it is possible to efficiently use multiple SRS resource sets for transmission and/or reception of PUSCH repetitions, especially in Frequency Range 2 (FR2) in which an uplink transmit beam may be formed with a narrower beam-width.

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： According to some embodiments, a method performed by a wireless device for transmitting a transport block comprises obtaining a first uplink aggregation factor. The first uplink aggregation factor is an integer value greater than one. The method further comprises obtaining a second uplink aggregation factor. The second uplink aggregation factor is an integer value greater than one and is different than the first uplink aggregation factor. The method further comprises: determining that a transport block is associated with a type of radio network temporary identifier (RNTI); selecting one of the first or second uplink aggregation factor based on the type of RNTI associated with the transport block; and transmitting the transport block on a physical uplink shared channel (PUSCH) according to the selected uplink aggregation factor.

摘要： According to an aspect, a wireless device receives a DCI configuration for a first set of DCI formats, each DCI of the first set of DCI formats having a same size measured as a number of bits. The wireless device receives a DCI configuration for a second set of DCI formats wherein the second set is different from the first set. The wireless device detects a first DCI from the first set of DCI formats and a second DCI from the second set of DCI formats based on the first DCI having a different size to the second DCI and the second DCI comprising at least one padding bit. According to another aspect a base station configures a wireless device with at least one DCI format from a first set of DCI formats wherein each DCI of the first set of DCI formats having a same size measured as a number of bits, and at least one DCI format from a second set of DCI formats wherein the second set is different from the first set and wherein the first DCI having a different size to the second DCI and the second DCI comprising at least one padding bit.

摘要： Systematic size matching procedures for downlink control information, DCI, provide exact instructions on how DCI size matching is to be performed in a NR wireless system, to meet predetermined limits for how many different DCI sizes may be monitored by a user equipment, UE. With these procedures, consistent and exact DCI size matching can be performed while keeping blind decoding procedures manageable, ensuring common understanding of DCI contents between the UE and the network.

摘要： Embodiments herein relate to a method performed by a radio node (13) for managing communication of one or more wireless devices (10) within a wireless communication network (1); which wireless communication network (1) comprises a radio access network node (12) serving the radio node (13). The radio node (13) receives an indication of radio resources out of a total spectrum of radio resources controlled by the radio access network node (12) for communication over a first radio interface using a first radio access technology, which indicated radio resources are allocated to the radio node (13) from the radio access network node (12) for communication over a second radio interface, which second radio interface uses a second radio access technology being different than the first radio access technology. The radio node (13) allocates at least part of the indicated radio resources for communication to and/or from the one or more wireless devices (10) over the second radio interface.

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.
