Abstract: Embodiments of the present disclosure relate to apparatuses, methods and computer readable storage media for contention window size (CWS) adjustment feedback. The first device comprises at least one processor; and at least one memory including computer program codes; the at least one memory and the computer program codes are configured to, with the at least one processor, cause the device at least to receive at least one transport block from a second device on a predetermined bandwidth part for a transmission from the second device to the first device, the at least one transport block transmitted in a set of subbands of the predetermined bandwidth part; generate a feedback based on a set of reception states of the at least one transport block in the set of subbands; and transmit the feedback to the second device so that the second device adjusts a contention window size (CWS) for a further transmission from the second device to the first device. In this way, a feedback corresponding to interference conditions with a certain subband may be provided for the CWS adjustment and the signalling overhead is significantly reduced.

Abstract: Various communication systems may benefit from appropriate configuration of reception states. For example, certain wireless communication systems, such as new radio, may benefit from control monitoring upon receipt of a discontinuous reception trigger. A method can including receiving, by a user equipment, configuration of a search space set of a downlink control resource set with a first monitoring periodicity. The method can also include receiving a trigger or the user equipment becoming active after a period without physical downlink control channel (PDCCH) monitoring. The method can further include, after the receiving of the trigger or the becoming active, modifying a monitoring periodicity of the search space set to a second monitoring periodicity.

Abstract: Systems, methods, apparatuses, and computer program products for managing or monitoring of the control channel in new radio (NR) through blind searches are provided. One method may include configuring, by a network node, multiple search spaces, sets of search spaces, and/or control resource sets, to a user equipment, that results in monitoring occasions where more blind decodings are required than allowed by capability of the user equipment. The method may further include identifying the monitoring occasions for which an allowed number of blind decodings is exceeded, determining a reduced set of blind decodings and/or candidates determined by predefined search space priorities or rules, and transmitting physical downlink control channel(s) to the user equipment given the reduced set.

Abstract: A network node, such as an eNB, allocates a PRB allocation for transmission of at least one user-specific RS. The at least one user-specific RS is configured to be transmitted in a pattern. The at least one user-specific RS is transmitted to a UE. The pattern of the at least one user-specific RS includes at least one over-the-edge RS transmitted outside of the PRB allocation. A UE receives at least one user-specific RS in a pattern, and performs channel estimation based on the at least one user-specific RS. At least part of the at least one user-specific RS is in a PRB allocation of the UE and the pattern of the at least one user-specific RS includes at least one over-the-edge RS received outside of the PRB allocation of said UE.

Abstract: Various communication systems may benefit from a reduction in latency. For example, communication systems may benefit from an improved transmission of an uplink reference signal in an uplink channel. A method, in certain embodiments, includes determining by a user equipment a candidate location of a transmission of an uplink reference signal in a channel. The method also includes determining by the user equipment a triggering window associated with the candidate location of the transmission of the uplink reference signal in the channel. In addition, the method includes receiving an uplink grant for a data transmission from a base station. Further, the method includes transmitting the uplink reference signal based on the uplink grant being at least partially within the triggering window.

Abstract: A method comprises transmitting from a user device information on first and second hybrid automatic request acknowledgement bits and a scheduling request in a same transmission time interval. The information on said first and second hybrid automatic request acknowledgement bits and said scheduling request are transmitted via first and second physical resource blocks using one or more resources of a set of resources. At least one of the resources of the set of resources differs from the one or more resources of the set of resources used to transmit information on the first and second hybrid automatic request acknowledgement bits when there is no scheduling request.

Abstract: Various communication systems may benefit from an improved resource block group allocation in a cell. A method may include determining at a network entity a common frequency resource allocation grid in a cell. The method may also include configuring at the network entity a frequency location of a bandwidth part of a user equipment within the cell. The frequency location of the bandwidth part may be offset from a reference point of the common frequency resource allocation grid. In addition, the method may include determining a size of one or more of a plurality of resource block groups within the bandwidth part of the user equipment based on the frequency location of the bandwidth part and the reference point. Further, the method may include transmit downlink control information from the network entity to the user equipment.
