Problems solved by technology

However, in cases where the delay reaches a threshold duration (e.g., ~symbol duration), the delay of the SRS may be sufficient to cause overlap in time and frequency with scheduled PUCCH transmissions in the cell, causing signal "collisions"
To avoid this situation (which creates interference that may render one or both of the SRS and PUCCH unrecognizable by the receiver), one or more subsequent slots can be canceled or "dropped", thereby resulting in Waste of system resources and reduction of system throughput

Embodiment Construction

[0016] figure 1 A wireless communication system 10 is shown in accordance with one or more embodiments. System 10 includes network nodes 106 (eg, but not limited to, base stations, eNBs, gNBs, etc.). System 10 also includes a UE 102 (also referred to herein as a "terminal," "user terminal," etc.) in communication with a network node 106 . The communication may also include uplink control signaling 20 and downlink control signaling 18 in addition to uplink and downlink transmission of user / application data. In some examples, uplink control signaling 20 may be performed over a PUCCH or Physical Uplink Shared Channel (PUSCH). In some examples, if UE 102 has been allocated resources for data transmission in the current subframe, then uplink control information (including HARQ acknowledgment) is sent on PUSCH along with the data. On the PUCCH, if the terminal has not been allocated resources for data transmission in the current subframe, the user data is sent separately from the...

Abstract

A user equipment (UE) (102) performing control signal transmission according to a single-segment subframe format (21) is described. In an aspect, the UE (102) selects the single-segment subframe format (21) instead of the multi-segment subframe format (22) as the uplink transmission format of the subframe. The selection may be based on an indication received by the network node that the single-segment subframe format (21) is to be used for transmitting the one or more control signals. Additionally, the UE (102) transmits one or more control signals on an uplink control channel using a single-segment subframe format (21).

Description

technical field [0001] The present disclosure relates generally to wireless communication systems, and in particular to uplink control channel transmissions within wireless communication systems. Background technique [0002] In today's wireless communication systems, user equipment (UE) communicates with a network node (such as a base station, eNB, or other network device) to receive data. In order to maintain channel and data transmission integrity, the UE may also send control signaling to the network node on one or more uplink channels. For example, the uplink control signaling from the UE to the network node may include a hybrid automatic repeat request (HARQ or H-ARQ) acknowledgment (acknowledgment) for the received downlink data, and UE reporting on downlink channel conditions and / or scheduling requests indicating that the UE needs uplink resources for uplink data transmission. [0003] For example, the uplink control signaling may be sent on a physical uplink cont...
