An apparatus for User Equipment, UE (102, 200), the apparatus comprising hardware processing circuitry, the hardware processing circuitry being configured to cause the UE (102,200) to: receive, from an Evolved Node B, eNB (104, 300), one or more downlink control messages that indicate an allocation of physical uplink control channel, PUCCH, channel resources that are included in network channel resources; and transmit an uplink control message in at least a portion of the allocated PUCCH channel resources, wherein: when the PUCCH channel resources are allocated according to an edge configuration, the PUCCH channel resources are restricted to a lower edge portion and an upper edge portion of the network channel resources, wherein the lower edge portion is near a lower edge of a frequency range of the network channel resources and the upper edge portion is near an upper edge of the frequency range of the network channel resources, when the PUCCH channel resources are allocated according to a distributed configuration, the PUCCH channel resources include one or more middle portions of the network channel resources, the middle portions partially overlapping with or not overlapping with the lower edge and upper edge portions, the downlink control messages indicate that the PUCCH channel resources are allocated in accordance with either the edge configuration or the distributed configuration, a first portion of the uplink control message is transmitted during a first slot in a first resource block, RB, included in the allocated PUCCH channel resources, when the uplink control message is transmitted according to a localized slot configuration, a second portion of the uplink control message is transmitted during a second slot in the first RB, and when the uplink control message is transmitted according to a non-localized slot configuration, the second portion of the uplink control message is transmitted during the second slot in a second RB included in the allocated PUCCH channel resources, and wherein the slot configuration for the PUCCH transmission is based on the one or more downlink control messages. when the PUCCH channel resources are allocated according to an edge configuration, the PUCCH channel resources are restricted to a lower edge portion and an upper edge portion of the network channel resources, wherein the lower edge portion is near a lower edge of a frequency range of the network channel resources and the upper edge portion is near an upper edge of the frequency range of the network channel resources, when the PUCCH channel resources are allocated according to a distributed configuration, the PUCCH channel resources include one or more middle portions of the network channel resources, the middle portions partially overlapping with or not overlapping with the lower edge and upper edge portions, the downlink control messages indicate that the PUCCH channel resources are allocated in accordance with either the edge configuration or the distributed configuration, a first portion of the uplink control message is transmitted during a first slot in a first resource block, RB, included in the allocated PUCCH channel resources, when the uplink control message is transmitted according to a localized slot configuration, a second portion of the uplink control message is transmitted during a second slot in the first RB, and when the uplink control message is transmitted according to a non-localized slot configuration, the second portion of the uplink control message is transmitted during the second slot in a second RB included in the allocated PUCCH channel resources, and wherein the slot configuration for the PUCCH transmission is based on the one or more downlink control messages.
