  • Publication number: 20230057016
    Abstract: Embodiments include methods, performed by a user equipment (UE), for receiving system information (SI) associated with a cell in a wireless network. Such methods include receiving, from the wireless network, a master information block (MIB) including SI associated with the cell. The MIB can be applicable to both a first frequency band and a second frequency band that have a common frequency range. Such methods also include determining whether the MIB applies to the first frequency band or the second frequency band. Other embodiments include complementary methods performed by a network node serving the cell in the wireless network, as well as UEs and network nodes configured to perform operations corresponding to such methods.

    Abstract: Embodiments include methods for a network node to activate semi-persistent sounding reference signal (SP-SRS) resources for transmission by a user equipment (UE). Such methods include sending, to the UE, a control message comprising configuration of a set of SP-SRS resources associated with a particular serving cell of the wireless communication network. Such methods include sending to the UE a further control message for activating the configured set of SP-SRS resources. The further control message includes information identifying an SP-SRS resource of the set of SP-SRS resources to be activated, and an indication of the identified SP-SRS resource's spatial relation with a further resource that is not associated with the particular serving cell.

  • Publication number: 20230017702
    Abstract: In some embodiments, a network (e.g., a TRP) provides to a UE information indicating that a transmitted “first” RS resource (or “RS” for short) is quasi-co-located (QCL) with a scheduled transmission for the UE (e.g., a “second” RS). The UE may then receive the scheduled transmission under an assumption that the scheduled transmission (e.g., a second RS, such as a demodulation RS (DMRS)) is QCL with the first RS. The UE may receive such QCL information before, after or while receiving the first RS.

  • Publication number: 20220408478
    Abstract: Operation in unlicensed spectrum requires Clear Channel Assessment (CCA), where a transmitter must monitor the channel 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.

  • Publication number: 20220345269
    Abstract: Synchronization signal and Physical Broadcast Channel, SS/PBCH, block management. A network node determines whether a network condition is met, signals to a communication terminal to apply a first detection method for SS/PBCH block detection when the network condition is determined to be met, signals to the communication terminal to apply a second detection method for SS/PBCH block detection when the network condition is determined as not met, and transmits SS/PBCH blocks according to the first or the second SS/PBCH block detection method, based on whether the network condition is met. The communication terminal receives the signalling from the network node associated with the communication network, determines whether the indicated SS/PBCH block detection method is a first or a second SS/PBCH block detection method based on the received signalling, and applies, based on the determination, the first or the second SS/PBCH block detection method for SS/PBCH block detection.
