A wireless transmit receive unit (WTRU) may send a grant free transmission comprising a first and a second part, each of which may be associated with a priority. The first part's priority may be higher than the second part's priority. The WTRU may select a first back of value from a first range of back off values. The WTRU may determine whether the grant free transmission was successful. If the grant free transmission was not successful, the WTRU may send a retransmission of the grant free transmission, which may include the first part and may not include the second part. The retransmission may select a second back off value from a second range of back off values, which may be a larger than the first range of back off values. The second back off value may indicate the number of grant free resource to skip prior to sending the retransmission.

Grant-free uplink transmissions

Methods and apparatus are described. A station includes a transceiver and a processor, which receive a trigger frame for an uplink (UL) transmission. The trigger frame includes an indication of resource units (RUs) for random access in an upcoming UL high efficiency trigger based packet data convergence protocol data unit and an indication that the trigger frame is a poll for a buffer status report of the STA. The processor and the transceiver transmit a buffer status of the STA using a selected one of the indicated RUs.

Method and apparatus for multi-user concurrent random access for wireless local area networks (WLANS)

To extend a physical broadcast channel (PBCH) in wireless communications, an extended physical broadcast channel (EPBCH) transmission is generated with one or more legacy PBCH blocks and one or more EPBCH blocks within an extension window. A size of the extension window is determined based at least in part on a PBCH repetition number and a number of the legacy PBCH blocks relative to a number of the EPBCH blocks. The EPBCH transmission is transmitted by a base station (BS) to one or more user equipment (UE).

Physical broadcast channel extension in wireless communications

A user equipment (UE) reports channel state information for multiple transmission reception points (TRPs) to a network. The UE collects channel state information (CSI) corresponding to multiple transmission reception points (TRPs), receives a signal configured to trigger a semi-persistent CSI (SP-CSI) report from a first TRP of the multiple TRPs, generates a SP-CSI report that includes CSI corresponding to each TRP of the multiple TRPs and transmits the SP-CSI report to a cell associated with the multiple TRPs.

Reporting channel state information for multi-TRP operation

Systems and methods for user equipment (UE) capable of performing sidelink (SL) communications that account for overlapped SL resource pools of multiple radio access technologies (RATs) are disclosed. A UE may select, based on prioritizing non-overlapped resources over overlapped resources, one or more candidate resources and/or one or more transmission resources; may determine a power control configuration without considering SL pathloss corresponding to a first RAT when a second power control configuration determination for a second RAT does not consider SL pathloss; may select physical sidelink feedback channel (PSFCH) locations for PSFCH use from first PSFCH locations of resources of a first SL resource pool on a first RAT that do not overlap with a second SL resource pool on a second RAT according to a bitmap; and/or may select one of a PSFCH transmission and PSFCH reception using a data priority rule and/or a pool sharing rule.

Resource allocation for co-channel coexistence

A method and apparatus for determining a physical downlink control channel (PDCCH) search space monitoring configuration for a wireless device that specifies PDCCH monitoring for one subcarrier spacing (SCS) selected from a group of subcarrier spacings (SCSs) that are related to a spectrum in 5G new radio (NR) above 52.6 GHz are described. In one embodiment, the monitoring limits associated with each of the SCSs are applied per slot per CC and the user equipment (UE) decode complexity associated with performing the monitoring limits for the different SCSs in the group is equal. In one embodiment, the monitoring limits associated with each of the SCSs are for a slot group of a plurality of slots and are for application over a duration of the slot group.

System and methods for PDCCH monitoring in new radio

Systems and methods are provided to implement features in the IEEE 802.11ad+/ay protocols by utilizing combinations of analog and digital precoding (such as hybrid mmWave precoding) to enable multi-stream/multi-user transmissions. These systems and methods are also suitable for 5G wireless networks, such as found in 3GPP. These systems and methods address performing general precoder design, reducing of beam-training overhead with leak wave antennas, performing single-stage approximate precoding with enhanced SLS for SU-MIMO transmissions (eSLS1), performing multi-stage approximate precoding with enhanced SLS for SU-MIMO transmissions (eSLS2), and performing exact precoding with enhanced SLS for SU-MIMO transmissions.

Systems and methods for single user hybrid MIMO for mmWave wireless networks

A user equipment (UE) reports beam management information to a network. The UE receives a first group of multiple reference signals from a first transmission reception point (TRP) of a network, receives a second group of multiple reference signals from a second different TRP of the network, selects a first beam associated with one of the multiple reference signals of the first group, selects a second beam associated with one of the multiple reference signals of the second group and transmits a message to the network, the message including an indication of the selected first beam and second beam.

UE operations for beam management in multi-TRP operation

A method determines a number of physical sidelink shared channel (PSSCH) symbols and a number of PSSCH demodulation reference signal (DMRS) symbols that will occur in a timeslot that is used for scheduling. PSSCH DMRS locations in the timeslot are derived based on applying the PSSCH DMRS symbols and the PSSCH DMRS symbols to a look-up table. A number of PSSCH DMRS resource elements (REs) is calculated based on the PSSCH DMRS locations and a scheduled number of PSSCH sub-channels. This number of PSSCH DMRS REs is used to determine a transport block size (TBS) included in transmissions over a sidelink channel.

Determine a transport block size (TBS) included in transmissions over a sidelink channel

Apparatus and methods are provided to enhance communications for NTN. In some aspects, a base station (BS) comprises a processor configured to schedule an uplink transmission in response to an uplink transmission request from a user equipment (UE) using one or more subframes ranging from a first uplink subframe to a last uplink subframe. The processor is further configured to determine or receive a timing advance (TA) indicating amount of subframes transmitted during a time delay between the UE and the BS and schedule a downlink transmission aligned with the uplink transmission. The downlink transmission is blocked from subframes ranging from TA plus one or more subframes ahead of the first uplink subframe to TA minus one or more subframes ahead of the last uplink subframe. The processor is further configured to transmit and receive, via a non-terrestrial equipment, the uplink and the downlink.

Enhanced machine type communications (MTC) for non-terrestrial networks (NTN)

A user equipment (UE) is configured to receive message 3 (Msg3) transmissions. The UE receives a system information block (SIB) transmission from a base station of a wireless network, receives a downlink control information (DCI) transmission scheduling a message 2 (Msg2) transmission from the base station, receives the Msg2 transmission including an uplink (UL) grant for a message 3 (Msg3) initial transmission from the base station, determines the number of repetitions for the Msg3 initial transmission based on at least one of the SIB transmission, the DCI transmission, and the Msg2 transmission and determines a frequency hopping (FH) type and FH pattern based on at least one of the SIB transmission, the DCI transmission, and the Msg2 transmission.

Enhancement of message 3 for RACH procedure

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for communications between user equipment. One of the methods includes receiving, by a first device and from a second device, sidelink control information indicating a resource reservation for a single-slot resource for the second device to use to communicate with the first device; determining, by the first device and based at least in part on the sidelink control information, whether a potential resource collision exists when the first device is scheduled to communicate with another device using the single-slot resource or when the single-slot resource is reserved by another device; and in response to determining that the potential resource collision exists, sending, by the first device and within a predetermined number of slots from a reference slot, a collision message to cause the second device to determine another single-slot resource to use to communicate with the first device.

Inter-device communication

Systems and methods used by reduced sensing user equipment (UE) (relative to a full sensing UE) are disclosed herein. A UE performing partial sensing may use knowledge of resource reservation periods for a resource pool of one or more resources to reduce sensing as compared to the full sensing case. A UE performing resource re-evaluation and/or resource pre-emption may use one or more sensing windows that are relatively smaller than windows used in the full sensing case to reduce sensing. A UE performing prioritized resource selection may use a sensing window to determine availability of resources within it prioritized resource selection window with a high reliability, thereby reducing the need to spend power on other sensing methods (which may include full sensing methods). Combinations of these embodiments are also contemplated.

Power saving sensing for reduced sensing UES using resource re-evaluation and resource pre-emption

Systems and methods for sidelink (SL) resource pool resource use by a user equipment (UE) are disclosed herein. In some embodiments, when the UE performs contiguous partial sensing in addition to periodic partial sensing, the UE performs one of resource selection and resource re-evaluation based a size of a time gap between a slot where the UE has SL data and a first slot of periodic-based candidate slots within a resource selection window. In other embodiments, the UE performs contiguous partial sensing without additional periodic partial sensing in the case where a packet delay budget (PDB) for the SL data is greater than a threshold. In some embodiments, the UE performs periodic partial sensing for resource re-evaluation and/or resource pre-emption according to a set of periodicity values P(and optionally period definition data K). Restrictions on the use of random resource selection by the UE are also described.
