  • Publication number: 20200305149
    Abstract: Provided is a technique capable of reporting resource block allocation information with no waste when an allocated resource block is reported, because in the current LTE downlink, the waste of the amount of resource allocation information increases in some cases since a restriction is imposed such that 37-bit fixed scheduling information is transmitted. A resource block group consisting of at least one or more resource blocks continuous on the frequency axis is allocated to a terminal, and the number of controlling signals for reporting allocation information indicating the allocated resource blocks is determined.

  • Publication number: 20200275375
    Abstract: The present disclosure relates to transmitting and receiving improved wake-up signals (WUS) between a base station and a user equipment (UE). The UE can receive a configuration for discontinuous reception (DRX) or extended DRX (eDRX). The UE can also determine whether to monitor for a WUS during a DRX WUS time resource or an eDRX WUS time resource. In some aspects, the UE can determine whether to monitor for the WUS during the DRX WUS time resource or the eDRX WUS time resource based on a duration of a DRX time gap between DRX WUS resources and a paging occasion and an eDRX time gap between eDRX WUS resources and the paging occasion. The base station can configure the UE for DRX or eDRX. The base station can also determine whether to transmit a WUS during a DRX WUS time resource or an eDRX WUS time resource.

  • Patent number: 10756865
    Abstract: A pilot sequence sending method and apparatus are provided. In the disclosure, after first-time masking is performed on a pilot sequence based on a cyclic orthogonal matrix, second-time masking is performed on the pilot sequence on which first-time masking has been performed, so that a PAPR of the pilot sequence on which second-time masking has been performed is less than a PAPR of the pilot sequence on which first-time masking has been performed, and further, orthogonality of the pilot sequence on which second-time masking has been performed can be higher than that of the pilot sequence on which first-time masking has been performed. This ensures accuracy of channel estimation and frequency offset detection.

  • Publication number: 20200267754
    Abstract: Some techniques and apparatuses described herein provide for the determination of a gap for a scheduled communication involving multiple, different TBs. For example, some techniques and apparatuses described herein provide for the determination of a gap between two or more PDSCHs that are scheduled by a same DCI based at least in part on a UE capability, such as a processing time or a processing mode. Some techniques and apparatuses described herein provide for the determination of a gap between a last PDSCH and a next PDCCH based at least in part on the UE capability. The gap(s) may permit the UE to successfully receive and/or decode multiple PDSCHs and/or PDCCHs in view of the limitations imposed by the UE's processing time or processing mode. In this way, efficiency of PDSCH/PDCCH resource utilization may be improved, the likelihood of a failed PDCCH transmission is reduced, and network efficiency is improved.

  • Publication number: 20200252972
    Abstract: Methods, systems, and devices for increasing physical random access channel (PRACH) capacity using orthogonal cover codes (OCCs) in wireless communications systems are described. A base station may transmit a PRACH configuration that indicates PRACH resources for system access, for example, in a system information block (SIB). A user equipment (UE) may receive the PRACH configuration, and may identify PRACH resources that support OCCs for system access. For example, PRACH configurations with small time domain spacing between PRACH resources may support OCCs. The UE may determine whether to transmit random access (RACH) preamble messages using OCCs in the PRACH resources, and may transmit a RACH preamble message to the base station based on the determination. In some cases, the base station may additionally indicate PRACH resources not configured for OCCs, and the UE may determine which set of resources to transmit in based on one or more parameters.
