  • Random access procedure
    Patent number: 11917687
    Abstract: According to certain embodiments, a method performed by a wireless device comprises initiating a random access procedure in which the wireless device sends a Physical Random Access Channel, PRACH, preamble to a network node and applying a receiver configuration for receiving an access response. The receiver configuration is determined based at least in part on whether a many-to-one association exists between (a) a downlink signal that can be used for beam selection prior to initiating the random access procedure, and (b) PRACH preamble indices.

  • Coherent detection of large physical random access control channel (PRACH) delays
    Patent number: 11812416
    Abstract: According to embodiments described herein, a long delay-detector improves delay estimation performance for PRACH for many practical deployment scenarios. This, for example, reduces the risk that the timing advance of the UE is set incorrectly and hence reduces the risk that subsequent communication fails and that the UE spreads unnecessary interference to other communication in the system.

  • Determination of PRACH Occasions and PUSCH Occasions for 2-Step Random Access
    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.

  • CONFIGURING RANDOM ACCESS CHANNELS FOR WIRELESS COMMUNICATIONS
    Publication number: 20220248459
    Abstract: According to some embodiments, a method for use in a wireless communication network includes a wireless device receiving, from a network, a configuration corresponding to a Physical Random Access Channel (PRACH). The wireless device receives, from the network via Radio Resource Control (RRC) signaling, a bitmap that provides an indication of time locations corresponding to synchronization signal (SS) blocks. The wireless device determines, based on the configuration and the bitmap, a time slot that does not overlap with the time locations to perform a PRACH transmission during the determined time slot.

  • METHOD FOR ACCESSING A CELLULAR COMMUNICATIONS NETWORK IN UNLICENSED SPECTRUM
    Publication number: 20220225411
    Abstract: A method for accessing a cellular communications network in unlicensed spectrum is provided. More specifically, the method is related to performing a Listen-Before-Talk (LBT) procedure prior to transmitting a Physical Random Access Channel (PRACH) preamble for accessing a New Radio-Unlicensed (NR-U) network. A User Equipment (UE) first performs the LBT procedure. If the LBT procedure is successful, the UE then generates a punctured PRACH preamble and transmits the punctured PRACH preamble. By puncturing the PRACH preamble, it is possible to create a gap(s) for performing the LBT procedure in a way that is backward compatible with existing NR-U specification and does not reduce a number of random access occasions in a slot or a mini-slot. As a result, it is possible to transmit PRACH preambles in consecutive random access occasions, thus helping to increase spectrum utilization and reduce latency in the cellular communications network.
