The NGV PPDU may be transmitted according to various bandwidths and frequency spacings. The NGV PPDU may be transmitted on the basis of a guard region having a first subcarrier index range, a direct current (DC) region having a second subcarrier index range, and a data and pilot area having a third subcarrier index range. | 2022-02-10 |
20220045813 | DMRS BUNDLING SCHEMES FOR UPLINK NON-CODEBOOK TRANSMISSIONS - Methods and apparatuses are provided for configured grant (CG) type 1 (CG1)-physical uplink shared channel (PUSCH) transmission. A method includes a user equipment (UE) determining, based on a sounding reference signal (SRS) resource indicator (SRI), a precoding matrix for a CG1-PUSCH transmission, processing a demodulation reference signals (DMRS) using the determined precoding matrix; and transmitting the processed DMRS across bundled DMRS resources of a set of CG1-PUSCHs. | 2022-02-10 |
20220045814 | DMRS CONFIGURATION METHOD AND USER EQUIPMENT - Disclosed in the present invention are a DMRS configuration method and a user equipment. Said method comprises: determining a time domain position of a first DMRS according to a first PUSCH duration and DMRS configuration information, the first PUSCH being obtained by splitting a second PUSCH. | 2022-02-10 |
20220045815 | TRAINING SEQUENCE TRANSMISSION METHOD AND APPARATUS - This application provides a training sequence transmission method and apparatus. The method includes: A first AP broadcasts a trigger frame, where the trigger frame indicates a time sequence of separately sending channel sounding frames by N STAs, and N is an integer greater than 1. The first AP receives the channel sounding frames sequentially sent by the N STAs, where one channel sounding frame includes one or more training sequences. In this solution, only one trigger frame needs to be sent, so that the N STAs can be triggered to separately report channel sounding frames to M+1 APs. However, in the conventional technology, each AP needs to send one channel training request to each STA, that is, N×(M+1) channel training requests are sent in total, to trigger each STA to report a training sequence. Therefore, this solution can significantly reduce signaling overheads. | 2022-02-10 |
20220045816 | USER EQUIPMENT AND BASE STATION PERFORMING TRANSMISSION AND RECEPTION OPERATIONS - The present disclosure relates to a user equipment, a base station and respective methods. The user equipment (UE) receives a single uplink grant for a plurality of PUSCH transmissions. The single uplink grant comprises an antenna port field with an index value that is to be used for the plurality of PUSCH transmissions. The UE determines time-domain resources based on the received uplink grant. The determined time-domain resources prescribe a number of PUSCH transmissions and a length of each of the number of PUSCH transmissions. The UE transmits the number of PUSCH transmissions using the determined time-domain resources. Each of the number of PUSCH transmissions comprises at least one front-loaded demodulation reference signal, DMRS. In particular, the UE determines a number of symbols to be used for each of the at least one front-loaded DMRS of the number of PUSCH transmissions based on the received index value, and, in case at least two of the number of PUSCH transmissions have different lengths, and in case different numbers of symbols are permissible for each of the at least one front-loaded DMRS, the UE transmits the same or a smaller number of PUSCH transmissions such that, for none of the comprised at least one front-loaded DMRS, a different determined numbers of symbols is used. | 2022-02-10 |
