Network node, user device and methods thereof

Abstract

The invention relates to a network node and a user device. The network node (100) comprises a processor (102) configured to determine a resource indicator (110) comprising a first start index (I1) anda first number of frequency resources (N1), wherein the first start index (I1) and the first number of frequency resources (N1) are used for allocating a first set of contiguous frequency resources (R1) within a first sub-band, and a corresponding first set of contiguous frequency resources (R1') within a second sub-band, wherein the first sub-band and the second sub-band are non-overlapping andcomprise equal number of frequency resources, a transceiver (104) configured to transmit a transmission grant (120) comprising the resource indicator (110) to a user device (300). The user device (300) comprises a transceiver (302) configured to receive a transmission grant (120) comprising a resource indicator (110) from a network node (100), the resource indicator (110) comprising a first startindex (I1) and a first number of frequency resources (N1), wherein the first start index (I1) and a first number of frequency resources (N1) are used for allocating a first set of contiguous frequencyresources (R1) within a first sub-band, and a corresponding first set of contiguous frequency resources (R1') within a second sub-band, wherein the first sub-band and the second sub-band are non- overlapping and comprise equal number of frequency resources; a processor (304) configured to derive the first start index (I1) and the first number of frequency resources (N1) based on the resource indicator (110); wherein the transceiver (302) is configured to transmit data symbols to the network node (100) using the first set of contiguous frequency resources (R1) and the corresponding first set of contiguous frequency resources (R1'). Furthermore, the invention also relates to corresponding methods, a wireless communication system, a computer program, and a computer program product.

Description

technical field

[0001] The invention relates to a network node and user equipment for a wireless communication system. Furthermore, the invention relates to corresponding methods, wireless communication systems, computer programs and computer program products. Background technique

[0002] In the Long Term Evolution (LTE) uplink, a Single Carrier-Frequency Division Multiple Access (Single Carrier-Frequency Division Multiple Access, SC-FDMA) waveform is used and is used for the Physical Uplink Shared Channel (Physical Uplink Shared Channel, PUSCH) time-frequency resources can be allocated by single-cluster or dual-cluster frequency resources, where each cluster (that is, frequency resource set) is positioned on a frequency within a time slot, and consists of several frequency-contiguous physical Resource block (Physical Resource Block, PRB) composition. A single Discrete Fourier Transform (DFT) precoder is applied to the one or two clusters. Thus, single-cluster achieves t...
