Problems solved by technology

An alternative would be to not schedule frequencies that overlap the "???" marked area, but this is inefficient, especially if you take into account the Figure 2 may occur multiple times in a time slot - each UE sends PUSCH and PUCCH at the same time once

Embodiment Construction

[0062] In the following, for easier reading, it is referred to as PUCCH instead of PUCCH resource structure, and as PUSCH instead of PUSCH resource structure.

[0063] Instead of moving the PUCCH close to the PUSCH, it is proposed to move the PUCCH within the scheduled PUSCH resources to be adjacent to the PUSCH in both time and frequency domains respectively. The scheduler / network node knows when PUCCH is expected to be sent simultaneously with PUSCH and can schedule resources to accommodate both PUSCH and PUCCH. It should be noted that the UE may transmit accordingly based on determining to transmit the PUCCH and the PUSCH at the same time, so that the network node does not need to configure such a channel resource structure arrangement within the scheduled resource structure.

[0064] The shape of PUSCH+PUCCH is rectangular again, and there is no figure 2 Issues with resources marked with "???".

[0065] Reduces intermodulation products, thereby reducing required power c...

Abstract

This invention relates to a method for operating user equipment (10), UE, in a radio access network. The method comprises transmitting signaling on a physical uplink control channel, PUCCH, resource structure and on a physical uplink shared channel, PUSCH, resource structure. The PUCCH resource structure covers a PUCCH time interval and a PUCCH frequency interval, and the PUSCH resource structurecovers a PUSCH time interval and a PUSCH frequency interval. The PUSCH time interval is longer than the PUCCH time interval. Further, the PUCCH resource structure is neighbored in frequency domain bythe PUSCH resource structure at least for a part of the PUCCH time interval and the PUCCH resource structure is neighbored in time domain by a further PUCCH resource structure or the PUSCH resource structure. The invention also relates to related devices and methods.

Description

technical field [0001] The present disclosure relates to wireless communication technologies, and more particularly to uplink transmissions. Background technique [0002] For NR, such as figure 1 As shown in , it has been agreed to support simultaneous transmission of PUSCH and PUCCH (this mode has also been introduced for LTE Rel-10). Simultaneous transmission of PUSCH and PUCCH is conceptually simple as it modifies neither PUSCH nor PUCCH structure as if both channels were sent in parallel. [0003] Typically, PUCCH occurs at semi-statically configured resources (possibly indicated together with some dynamic indication included in the DCI). Semi-statically configured resources are usually ("common settings") placed at the band edges, and the PUCCH frequency hops between them to achieve frequency diversity. [0004] PUSCH transmissions are usually scheduled dynamically. Therefore, it is common that PUCCH and PUSCH transmissions may occur at disjoint frequencies, with th...
