Abstract: A user equipment (UE) monitors a Physical Downlink Control Channel (PDCCH). The UE receives a configuration for a physical downlink control channel (PDCCH) including repetitions for PDCCH candidates comprising first PDCCH data, wherein the PDCCH candidates are repeated across multiple durations of a DL resource grid, detects, based on a repetition detection scheme, each of the PDCCH candidates and combines soft bits from each of the PDCCH candidates, wherein the combined soft bits are jointly decoded to determine the first PDCCH data and calculates a number of blind decodes (BDs) for the durations of the DL resource grid carrying the PDCCH candidates, wherein at least one BD value for the PDCCH candidates is scaled by a scaling factor for the calculation of the number of BDs.

Abstract: Approaches for performing Physical Uplink Shared Channel (PUSCH) transmissions include receiving, by a user equipment (UE) from a base station, an indicator of a plurality of precoders corresponding to M Physical Uplink Shared Channel (PUSCH) repetitions, wherein M is an integer. A plurality of precoders corresponding to two or more of the M PUSCH repetitions are indicated. The UE configures the plurality of precoders based on the indicator and transmits one or more of the M Physical Uplink Shared Channel (PUSCH) repetitions corresponding to one or more of the plurality of precoders. The indicator can be provided in higher layer signaling. One or more transmission rank indicator (TRIs) and transmission precoder matrix indicators (TPMIs) for the M PUSCH repetitions can be provided. The indicator can be provided in a scheduling downlink control indicator (DCI) communication. The indicator can also be provided within N sounding reference signal (SRS) resource indicator(s) (SRIs) of the scheduling DCI.

Abstract: Methods and apparatuses are disclosed for calculating and compensating for Doppler shift in a high-speed environment. When in a high-speed environment, Doppler shifts on a transmitted radio frequency signal can become extremely large, which may make it difficult or even impossible for a receiving device to accurately decipher the signal. Therefore, embodiments of the present disclosure describe how tracking reference signals can be transmitted from multiple transmission/reception points, and processed by the UE. For example, the TRS transmitted from the TRP can be enhanced to allow for TRS information from two different TRPs. Additionally, or alternatively, a flag can be set within TRS information that identifies it as having originated from either a first TRP or a second TRP. Additionally, the UE can calculate Doppler shift information and report that information back to the base station in a report message, such as an SRS message. In this manner, the base station can precompensate for the Doppler shift.

Abstract: A base station (BS) configures a user equipment (UE) with parameters for channel access operations on a shared channel. The BS transmits to the UE a first configuration for a BS-initiated fixed frame period (FFP) (BS-FFP) and a second configuration for a UE-initiated FFP (UE-FFP), wherein the BS-FFP overlaps the UE-FFP, schedules an uplink (UL) transmission during the UE-FFP and when there is no downlink (DL) transmission in the BS-FFP, receiving the UL transmission from the UE during the BS-FFP.

Abstract: A user equipment (UE) may attempt to access a base station of a network. The UE receives, from the base station of a wireless network, a broadcast including a system information block (SIB) identifying a plurality of random access channel (RACH) sub-bands of an uplink (UL) bandwidth and which of the plurality of RACH sub-bands includes physical random access channel (PRACH) resources. The base station selects one of the plurality of RACH sub-bands for a PRACH transmission and selects a preamble from the selected RACH sub-band and transmit the preamble to the base station to initiate a RACH procedure.

The base station determines that a control resource set (CORESET) is to be shared by at least a first TRP and a second TRP corresponding to a cell of a network, performs resource element group (REG) bundle to virtual REG bundle mapping on a per TRP basis, wherein multiple REG bundles are indexed on the per TRP basis, performs virtual REG bundle interleaving across the first TRP and the second TRP, performs control channel element (CCE) to interleaved REG bundle mapping and transmits downlink control information (DCI) using the CORESET, wherein the CORESET is configured based on, at least, the CCE to interleaved REG bundle mapping.
