An apparatus may be configured to: receive, from a network, an indication of one or more sets of ports, wherein the one or more sets of ports are grouped; receive, from the network, at least one parameter for port interference detection, wherein the at least one parameter for port interference detection comprises at least one of: a scrambled cyclic redundancy code, a number of interfered ports, a set index for a set of at least one of the one or more sets of ports, or an indication of a selected set of the one or more sets of ports; and determine the set of at least one of the one or more sets of ports based, at least partially, on the at least one parameter for port interference detection.

Efficient signaling for MU-MIMO enhanced receivers

In one embodiment, an apparatus performs receiving, via two different signal pathways, at least two different signals that are associated with different radio wave characteristics; changing the frequency of signal(s) to provide intermediate signal(s) with each having different frequencies; multiplexing the intermediate signals to allow signals to be transmitted together via a single wired connection; receiving a multiplexed signal via the single wired connection, the multiplexed signal including intermediate further signals having different frequencies, the intermediate further signals also being associated with differing radio wave characteristics; and separating the intermediate further signals into separate signals; changing the frequency of the further signals to provide further signals at a transmission frequency; and transmitting the further signals via the two signal pathways.

Apparatus, method, computer program for repeating signals

Techniques for providing a multiple donor supported repeater within a communication network are disclosed. An example of such techniques includes an apparatus which establishes a control channel with a respective donor node of one or more donor nodes. The apparatus receives an indication of resource information from the one or more donor nodes via the corresponding control channel. The apparatus determines a grid of physical repeater beam channels to cover an access area based at least in part on the received indication of resource information from the one or more donor nodes. Corresponding methods and computer program products are also provided.

Multiple donor supported directional repeater

According to an example aspect of the present invention, there is provided an apparatus, such as a user equipment, including at least one processing core, at least one memory including computer program code, the at least one memory and the computer program code being configured to, with the at least one processing core, cause the apparatus at least to initiate a random access process with a network by transmitting an initial random access message to the network, receive a random access response from the network, the random access response including a timing advance command bit sequence, determine from the timing advance command bit sequence a timing advance value and a configuration parameter, and transmit a request message to the network at least once in compliance with the configuration parameter.

Transmission of parameter

A UE receives configuration for interference mitigation pattern(s) indicating which resource elements in a time-frequency resource space should be measured. The UE performs interference measurements based on the received one or more interference mitigation patterns. A network node determines configuration for interference mitigation pattern(s0 indicating which resource elements in a time-frequency resource space should be measured by a user equipment. The network node sends, toward the user equipment, the configuration for use by the user equipment to perform interference measurements of the one or more interference mitigation patterns.

An apparatus comprising means for performing: grouping columns of a linear combination coefficient matrix into a predefined number of clusters; and sending at least one of the clusters in a second part of a uplink control signalling transmission of a channel to an access node, wherein the uplink control signalling transmission comprises a first part and the second part.

Apparatus, method and computer program for uplink control signalling

Methods and apparatus, including computer program products, are provided for increasing uplink beamforming gain. In one aspect there is provided a method of identifying user equipment which makes use of the proposed new beam-sweeping random access channel procedure that enables the base station to identify the best uplink transmit beam rather than the first beam that the base station managed to detect. Related apparatus, systems, methods, and articles are also described.

Methods for UL RACH coverage extension
