Abstract: The present disclosure relates to telecommunications. In one of its aspects, the disclosure concerns a method in a BS for time domain resource scheduling for group transmissions in a wireless communication system, which comprises the BS and a plurality of UEs, including a first UE. The plurality of UEs are assigned to a group. At least two of these UEs have data for group transmission to the BS. An aggregated BSR comprising BSRs from the at least two UEs is received from the first UE. The BS schedules time domain resources for at least one of SL transmissions of the data within the group and cooperative UL group transmissions of the data from the UEs to the BS. At least one bitmap indicating the scheduled time domain resources is generated and transmitted to the first UE. Each bit in each bitmap corresponds to a potential transmission in the corresponding UL and SL.

Abstract: A method performed by a wireless device is described herein. The wireless device operates in a wireless communications network. The wireless device provides a message to be sent to a network node operating in the wireless communications network. The message is a first scheduled message to be sent to the network node in a random access procedure. The message comprises a first indicator of a type of the message. The type of message has: a) a fixed size SDU, and b) a one byte header comprising the first indicator and lacking a second indicator of a length of a payload. The wireless device also initiates sending the provided message to the network node. Also described is a method performed by the network node receiving and initiating processing the message, based on the first indicator.

Abstract: The present disclosure relates to telecommunications. In one of its aspects, the disclosure concerns a method in a source User Equipment (UE) for group transmissions in a wireless communications system comprising a group of UEs, including the source UE. The group is assigned a first group IDentity (ID). The source UE has data to be cooperatively transmitted by the group of UEs in a group transmission to a Radio Access Network (RAN) node. The method comprises transmitting, to the group of UEs, a SideLink (SL) message. The SL message comprises the data to be transmitted to the RAN node, a source UE ID identifying the source UE, the first group ID identifying the group of UEs receiving the data and an indicator indicating that the data comprised in the SL message is to be transmitted cooperatively by the group of UEs in a group transmission to the RAN node.

Abstract: Buffer Status Reports (BSR), by which the network is made aware of uplink transmission needs of wirless devices, are specifically enabled to be transmitted using 2-step Random Access (RA), to reduce latency and network resource use. In one embodiment, 2-step RA configurations tailored to B SR-transmissions are introduced. These may, for example, use a subset of the configured resources in the configured 2-step RA resources for B SR. In another embodiment, conditions for triggering B SR over 2-step RA, depending on the traffic, are introduced. For example, the priority or the the delay budget of the traffic may be used to determine whether a BSR over 2-step RA should be triggered. In another embodiment, simplified procedures when receiving the response to MsgA are introduced. These may include, for example, not transmitting a full MsgB, but rather having the UE receive an UL grant.

Abstract: Various embodiments of the present disclosure provide a method for random access. The method which may be performed by a terminal device comprises receiving resource configuration information from a network node. The method further comprises determining an uplink resource for a feedback to a response message from the network node in a two-step random access procedure, based on the received resource configuration information.

Such methods include determining that further data for UL transmission is available before a second transmission opportunity that is after the first transmission opportunity, and determining whether the pending data or the further data should be prioritized for UL transmission during the second transmission opportunity. This prioritization determination can be based on various factors. Such methods can also include transmitting the pending data or the further data, during the second transmission opportunity, based on the prioritization determination.
