  • Publication number: 20210298093
    Abstract: Embodiments include methods for a user equipment (UE) to provide downlink (DL) channel-quality reports during a random-access (RA) procedure in a cell provided by a network node in a radio access network (RAN). Such embodiments include receiving, from the network node, a first indicator indicating that the UE may have to report DL channel quality in a particular message of the RA procedure; and initiating the RA procedure. The UE may be configured to operate in a coverage-enhancement (CE) mode. Such embodiments can also include initiating DL channel quality measurements based on the first indicator, wherein the DL channel quality measurements can be initiated before receiving a RA response from the network node. Other embodiments include complementary methods performed by a network node, as well as UEs and network nodes configured to perform the respective methods.

  • Publication number: 20210289426
    Abstract: A network node (200), a wireless device (202) and methods therein, for communicating or obtaining system information. The network node (200) transmits (2:1) a System Information Block Type1, SIB1, message that includes at least one other SIB than SIB1 as an extension. The wireless device (202) reads (2:2) the at least one other SIB in the SIB1 if the wireless device (202) is capable of reading the extension in the SIB1 message. The network node (200) may further transmit (2:1) the at least one other SIB in a subsequent separate System Information message. The wireless device (202) is then able to read (2:4) the at least one other SIB in the subsequently received System Information message if the wireless device (202) is not capable of reading the extension in the SIB1 message. Thereby, if the wireless device is capable of reading the extension in the SIB1 message it will acquire the system information earlier than if the other SIBs are only transmitted in less frequent System Information messages.
