Abstract: A wireless access network node transmits scheduling information assigning an uplink resource for a user equipment (UE), detects whether the UE has not transmitted using the assigned uplink resource, determines, based on the detecting, that the UE has failed a Listen-Before-Talk (LBT) check at the UE, and further schedules and assigns an uplink resource for the UE.

Abstract: In some examples, a first network node of a first network sends, in response to a request from a user equipment (UE) served by a second network, a transmission configuration to a second network node of the second network, the transmission configuration relating to a configuration used for a direct wireless transmission between the UE and a wireless device. The first network node sends scheduling information granting a resource for use by the UE in the direct wireless transmission.

Abstract: A method for transmitting a scheduling request includes receiving, at a relay UE and from a remote UE, a sidelink control information. The relay UE is within a coverage area of a base station. The remote UE is outside of the coverage area. The relay UE is configured to relay transmissions from the remote UE to the base station, and the sidelink control information indicates a future transmission of a data packet over a sidelink channel. A scheduling request is transmitted to a base station. A scheduling grant that indicates an uplink resource is received from the base station. A data packet over the sidelink channel is received from the remote UE.

Abstract: A channel sharing method includes determining a starting time for transmission on an LAA-LTE channel. A length of a hybrid preamble is determined based on the starting time and a predetermined transmission time boundary. Subsequent to determining the length of the hybrid preamble, the hybrid preamble having the determined length is transmitted. Subsequent to the hybrid preamble, a Long Term Evolution (LTE) signal is transmitted.

IPC: H04W4/10
CPC classification number: H04W4/10
Abstract: A network node communicates data of a first push-to-talk (PTT) group using a first multimedia broadcast/multicast service (MBMS) bearer, and data of a second PTT group using a second MBMS bearer. Responsive to a regrouping of the first PTT group and the second PTT group to form a regrouped PTT group, the network node communicates data of the regrouped PTT group using at least one of the first and second MBMS bearers.

Abstract: A method for allocating resources for device-to-device transmission between two or more user equipment (UEs) includes transmitting, from a first UE to a second UE, a resource allocation configuration for device-to-device communications. A resource request for a device-to-device transmission is received from the second UE. In response to the resource request, a resource for the device-to-device transmission is selected at the first UE. A resource grant is transmitted to the second UE. The resource grant identifies the selected resource. A device-to-device transmission is received from the second UE over the selected resource.

Abstract: Disclosed herein is a method at a User Equipment (UE) comprising determining that a current radio resource configuration is of a normal type, and responsive to the determining, prohibiting the UE from sending a Power Preference Indication (PPI) for a radio resource configuration of the normal type. Also disclosed is a method at a UE comprising: determining that a current radio resource configuration is of a power optimized type, and responsive to the determining, prohibiting the UE from sending a PPI for a radio resource configuration of the power optimized type. Also disclosed is a UE including a processor, the UE configured to: determine that a current radio resource configuration is of a normal type, and responsive to the determining, refrain from sending a PPI for a radio resource configuration of the normal type.

Abstract: An unlicensed wireless spectrum access point control circuit receives a first identifier from a first network entity and also receives a second identifier from a second network entity and then compares the late the first identifier to the second identifier to thereby authenticate the second network entity. By one approach the first and second identifier are medium access control (MAC) addresses. By one approach the first network entity comprises an Evolved Node-B base station in a Long Term Evolution (LTE) Radio Access Network and the second network entity comprises a portable wireless device. Upon authenticating the second network entity, the control circuit can then allow user plane data traffic.

Abstract: A wireless access network node determines that a user equipment (UE) has experienced a channel busy condition that prevented the UE from transmitting on an uplink to the wireless access network node. In response to the determining, the wireless access network node refrains from scheduling an uplink resource for the UE.
