摘要： Operation in unlicensed spectrum requires Clear Channel Assessment (CCA), where a transmitter must monitor the channekl before transmitting, to ensure it is free. An exception is a brief gap that allows for Rx/Tx turn-around, so that an ACK can be transmitted following reception, without performing a new CCA. NR introduces a 2-step Random Access (RA) procedure, where MsgA includes both a PRACH and a PUSCH transmission. To minimize CCA delays in unlicensed spectrum, only those RACH opportunities (ROs) and PUSCH opportunities (POs) that result in a very small delay between the PRACH and PUSCH transmissions of MsgA should be employed. RO configurations are defined for LTE 4-step RA. Embodiments provides methods for selecting which of these be may be shared for 2-step RA, for selecting which should be used in case of collisions, for selecting ROs and POs when the configurations are not shared, and for communicating RO configurations to UEs.

摘要： The present disclosure relates to radio network communication. In one of its aspects, the disclosure presented herein concerns a method performed by a first UE for transmitting group Buffer Status Reports (BSRs) for group transmissions to a Base Station (BS) in a wireless communication system. The wireless communication system comprises the BS and a plurality of UEs, including the first UE. The plurality of UEs are assigned to a group, wherein at least one of the UEs within the assigned group has data for group transmission to the BS. The method comprises transmitting, to the BS, a group BSR. The group BSR comprises at least one identifier identifying a request for SideLink (SL) transmissions within the assigned group and identifying a request for cooperative UpLink (UL) group transmissions of data by the UEs within the assigned group to the BS once the SL transmissions to the UEs within the assigned group are completed.

摘要： Methods and apparatuses are disclosed for PUSCH resource selection in 2-step random access (RA). In one embodiment, a wireless device is configured to receive a two-step RA configuration comprising: a first resource allocation for a PUSCH 5 transmission of a first message, msgA, of the two-step RA procedure, the first resource allocation for the PUSCH transmission of the msgA being associated with a first set of preambles; and a second resource allocation for the PUSCH transmission of the msgA associated with a second set of preambles; select one of the first and second resource allocation and the associated one of the first and second set of 10 preambles based on the two-step RA configuration and a payload size of the PUSCH transmission of the msgA; and transmit the PUSCH transmission of the msgA using the selected one of the first and second resource allocation.

摘要： Embodiments of the present disclosure provide methods and apparatuses for random access procedure. A method at a user equipment (UE) comprises selecting a synchronization signal and physical broadcast channel block (SSB) with a signal measured metric satisfying a criterion. The method further comprises transmitting a first message including a random access channel (RACH) preamble on a RACH occasion and data on an uplink shared channel (USCH) to a base station. The RACH preamble and the RACH occasion are selected based on a mapping of the SSB to the RACH preamble and the RACH occasion. The method further comprises receiving a second message from the base station as a response to the first message.

摘要： Systems, methods and apparatus are disclosed for user equipment and/or network nodes. An example method performed by a network node includes providing a shared resource to a plurality of user equipments (UEs) that are active on a bandwidth part (BWP). The network node receives a Scheduling Request (SR) on the shared resource of the BWP, and responsive to the SR, assigns one or more grants to one or more of the plurality of UEs that are provided with the shared resource. The network node monitors another resource, for a time window after the assigning of the one or more grants, and after receiving a transmission on the monitored resource from a UE, provides the UE with a dedicated resource on the BWP.

摘要： A method, a system and a controller for controlling the Quality of Service, QoS, of a wireless link, providing a service from a transmitting entity to a receiving entity is suggested. Once data, decisive of the QoS of the hops of the wireless link has been received, it is determined, based on the received data, that at least one QoS target-value of one of said hops is, or is predicted, not to be met. For each of the mentioned hops, one or more actions for achieving that said at least one QoS target-value is met, is initiated and based on the determining of one or more actions, instructions, instructing at least one of the mobile relay stations how to execute one or more of said determined actions are initiated.
