Abstract: Determination of characteristics of a communication environment may be beneficial in many communication systems. For example, certain wireless communication systems, such as fifth generation (5G) communication systems, may benefit from appropriate mobility measurements. A method can include performing, at a user equipment, beam-specific measurements of a plurality of beams of at least one cell. The method can also include calculating a cell quality based on the beam-specific measurements.

Abstract: Example embodiments of the present disclosure relate to a solution for determining a contention resolution timer. In an aspect, a first device receives, from a second device, an indication to perform Msg3 transmission. The first device transmits, to the second device, information of the first device for contention resolution. In case a configuration of a 4-step random access channel is unavailable in an active bandwidth part for the first device, the first device determines a duration for monitoring a contention resolution message based on one of: a first configuration of a 2-step random access channel in the active bandwidth part, or a second configuration of a 4-step random access channel in a bandwidth part different from the active bandwidth part. Example embodiments of the present disclosure can improve the performance of a random access procedure.

Abstract: A method comprising configuring a user equipment in a low activity state to operate within a radio access network wherein a radio access network notification area for the user equipment is defined based on a list of logically associated radio access network paging areas, wherein each of the logically associated radio access network paging areas is a subset of a core network tracking area identified by a paging area code value which is unique within the core network associated tracking area.

Abstract: A method including monitoring, by a user equipment (UE) operating in a multi-beam based communication session, signal qualities for a plurality of beams in the multi-beam based communication session (300); determining a beam link failure (BLF) occurring for at least one of the beams in the multi-beam based communication session (302); determining a type of the beam in which the beam link failure (BLF) is occurring (304); and updating a radio link failure (RLF) related condition in dependence on the type of the beam in which the beam link failure (BLF) is occurring (306).

Abstract: There is disclosed an apparatus. The apparatus comprises means for using a first random access type in a random access procedure; and in response to determining that a threshold number of failed random access attempts has been reached using the first random access type, determining whether to switch to using a second random access type which is different from the first random access type.

Abstract: To better support beamforming in MIMO systems such as 5G, a first match is determined between a first transmit (TX) beam group of a radio network and a first receive (RX) beam group of a user equipment (UE); and also a second match is determined between a second TX beam group of the radio network and a second RX beam group of the UE. For example these matches can come from the UE's beam report with best match information. The network configures the UE with at least a first discontinuous reception (DRX) configuration associated with the first RX beam group and with a second DRX configuration associated with the second RX beam group. In this case the first and second DRX configurations are active simultaneously for the UE, and each said beam group comprises at least one antenna or antenna port.

Abstract: A method, apparatus and computer program product are provided to manage and use access information in a transitional and/or multigenerational network environment. In some example implementations, an indication associated with the availability of services associated with a second network is received during the performance of procedures associated with a layer of a first network. Based at least in part on the indication associated with the availability of second network services in the location associated with a mobile device, a control signal is generated causing a reconfiguration of a mobile device. Some example embodiments arise in the context of the fifth generation (5G) networks deployed alongside Long Term Evolution (LTE) networks, such that the mobile device can be reconfigured based at least in part on the availability or unavailability of 5G service.

Abstract: A method is provided including determining a mapping of a scheduling request to one or more logical channels configured for a user equipment; in response to a received scheduling request, allocating an uplink radio resource such that a transmission time interval of the allocated uplink radio resource has a length corresponding to length of a transmission time interval configured for the mapped one or more logical channels; and receiving data on the allocated uplink radio resource. A further method includes transmitting a scheduling request mapped to one or more logical channels configured for a user equipment; receiving an allocation of an uplink radio resource wherein a transmission time interval of the allocated uplink radio resource has a length corresponding to length of a transmission time interval configured for the mapped one or more logical channels; and sending data on the allocated uplink radio resource.
