Abstract: Various communication systems may benefit from the appropriate selection of aspects of operation of the communication system. For example, certain wireless communication systems, such as fifth generation (5G), long term evolution advanced (LTE-A), and wireless local area network (WLAN) communication systems, may benefit from appropriate random access preamble selection. A method can include determining that a user equipment should consider at least one beam-specific parameter. The method can also include indicating to the user equipment to consider the at least one beam-specific parameter.

Abstract: Methods, apparatus and computer program products are disclosed for structuring Protocol Data Units (PDU). A method comprises: structuring a protocol data unit to include at least one special field in a header part of the protocol data unit and a padding part of the protocol data unit, wherein the at least one special field part indicates a length of the header part and wherein a length of the padding part is based at least on the indicated length of the header part; mapping the protocol data unit onto the trans port block scheduled for transmission between a source entity and a target entity, and transmitting the transport block from the source entity.

Abstract: Systems, methods, apparatuses, and computer program products for user equipment based timing advance measurements. The method may include receiving a layer 1/layer 2 triggered mobility configuration for one or more candidate target cells, wherein UE-based TA measurement is enabled for a plurality of cells comprising the one or more candidate target cells and performing user equipment-based timing advance measurements for the plurality of cells according to a first user equipment-based timing advance measurements behavior during a layer 1/layer 2 triggered mobility procedure. An indication to enable a second user equipment-based timing advance measurements behavior may be received. User equipment-based timing advance measurements for the plurality of cells according to the second user equipment-based timing advance measurements behavior based on the indication may be performed.

Abstract: Example embodiments of the present disclosure provide a solution for handling expiry of at least one time alignment timer (TAT) of multiple timing advance groups (TAGs) associated with a serving cell. In an example method, the terminal device receives determines at least two TAGs for a serving cell, wherein the at least two TAGs comprise a primary TAG and a secondary TAG. The terminal device determines whether at least one TAT of the at least two TAGs has expired and maintain, based on determining that the at least one TAT has expired, one of the primary TAG and the secondary TAG. In this way, only a single TAG is maintained once the terminal device has single TAT/no TAT running removing ambiguities in RA procedure/UL signal transmissions. Since the network is aware of the TAT expiry, it knows behaviour of the terminal device and can act accordingly.

Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer-readable storage medium for determination of concurrent beam failure. In some example embodiments, a terminal device detects a first beam failure associated with a first set of reference signals used for beam failure detection. The terminal device determines whether a second beam failure associated with a second set of reference signals used for beam failure detection is recovered in response to detecting the first beam failure.

Abstract: Systems, methods, apparatuses, and computer program products for facilitating triggered PDCCH-ordered PRACH transmissions in multi-TRP scenarios. One method may include a UE determining that a first TCI state is to be applied in a first slot and a second TCI state is to be applied in a second slot. The first TCI state is associated with a first TAG ID, a second TCI state is associated with a second TAG ID different than the first TAG ID, and the second slot is succeeding and adjacent to the first slot. The method may further include, based upon the determining, transmitting or dropping at least one of at least one uplink transmission in the first slot or at least one uplink transmission in a second slot.

Abstract: A method performed by a user device, including performing the steps of: receiving, from a network entity, one or both of: at least one resource of at least one downlink reference signal, and an indication; triggering switching, from a first association to a second association between at least two CORESETPoolIndex values and at least two sounding reference signal resource sets, based on a determination of one or both of: a measured value of the at least one DL reference signal and the indication; and transmitting respectively, to the network entity, corresponding resources of one or more sounding reference signals that correspond to the second association after the switching.

Abstract: Example embodiments of the present disclosure relate to an apparatus receiving an instruction to perform interchanging of an association of coreset pool indices with sounding reference signal (SRS) resource sets. The apparatus interchanges an association of a first coreset pool index with a first SRS resource set of the SRS resource sets and an association of a second coreset pool index with a second SRS resource set of the SRS resource sets to an association of the first coreset pool index with the second SRS resource set and an association of the second coreset pool index with the first SRS resource set. The apparatus transmits one or more SRS transmissions associated with the first or second coreset pool index and/or a physical uplink shared channel (PUSCH) transmission based on an SRS resource indicator (SRI) associated with the first or second coreset pool index, in accordance with the interchanged association.
