Abstract: Aspects and embodiments relate to a user equipment control method for user equipment operating to communicate with a network access node in a wireless communications network, and a computer program product and user equipment operable to perform that method. The method comprises: receiving, at user equipment, an indication of access criteria to be met in relation to at least two operational parameters associated with user equipment before user equipment can request transition from a first radio resource control state to a second radio resource control state, at least one of the operational parameters comprising: user equipment access group or user equipment access class; determining that user equipment requires a transition from the first radio resource control state to the second radio resource control state; assessing whether the user equipment meets the connection criteria in relation to said at least two operational parameters and, if so, requesting the transition from the first radio resource control state to the second radio resource control state. Aspects and embodiments may allow a network to admit user equipment based on combinations of static and dynamic characteristics, both in idle and connected mode.

Abstract: A method of controlling uplink multiple input multiple output transmission between user equipment and a base station of a wireless communications network, user equipment and a computer program product are disclosed. The method comprises the steps of: identifying whether insufficient capacity exists on a primary uplink stream to carry pending uplink data packets; and if insufficient capacity exists, preventing establishment of a secondary uplink stream when it is determined that pending uplink data packets which would not be carried by the primary uplink stream would under-utilize the secondary uplink stream. In this way, the disproportionate interference and consumption of resources that would otherwise result from the establishment of a secondary stream in order to carry relatively little data is avoided which reduces the resources utilized, increases power efficiency and minimizes interference.
