Abstract: A user equipment that supports a first set of beams accumulates transmit power control (TPC) commands to generate an accumulated correction factor during communication between the user equipment and a base station that supports a second set of beams. The user equipment is configured to use a first subset of the first set of beams during the communication and the base station is configured to use a second subset of the second set of beams during the communication. The user equipment detects a change in the first subset or the second subset. The user equipment resets the accumulated correction factor in response to detecting the change. In some cases, the user equipment generates a plurality of correction factors for a corresponding plurality of closed-loop processes. The user equipment resets some or all of the plurality of correction factors in response to detecting the change.

Abstract: Certain embodiments may relate to communication systems, and, for example, some embodiments may relate to beamforming techniques. According to an embodiment, a method may include, for each PDCCH search space candidate, one or more UE beams may be configured and/or assigned that correspond to one or more of the configured beam pairs. For each PDCCH search space candidate, one or more beam pairs, based on one or more corresponding downlink RS for beam management, may correspond to a configured UE beam. The UE may detect a PDCCH. Upon detecting a PDCCH, the UE can identify one or more configured beam pairs or a default beam pair within the PDCCH search space candidates.

Abstract: A base matrix is applied to an LDPC coder. The base matrix includes multiple parts, each including multiple of rows and columns, and containing integers, each representative of an identity matrix cyclically shifted in accordance with the integer or representative of an all-zero matrix. At least two of the multiple parts are configured such that their respective column-wise combinations of rows represents a same starting vector, cyclically shifted or interleaved, with zero or more but not all integers not indicative of the all-zero matrix of the same vector substituted by integers indicative of the all-zero matrix. The at least two of the multiple parts are not identical. The applied base matrix is used for one of encoding data using the LDPC coder or decoding data using the LDPC coder.

Abstract: A radio network sends downlink signaling to a user equipment (UE) that triggers an enhanced uplink beam selection protocol, based on quality of the UE's uplink signaling the network receives according to a basic uplink beam selection protocol. In response the UE transmits pre-defined signaling such as uplink beam references signals (U-BRS) with uplink beams according to the downlink signaling. The network measures and selects one or more of those uplink beams for the UE to use for sending uplink data, and notifies this selection to the UE. In various embodiments the basic uplink beam selection protocol is based on uplink-downlink reciprocity, the downlink triggering signaling is dynamic and further selects a subset of uplink beams, and multiple UEs can be triggered in common signaling where blind decoding by the UEs is enabled via a scrambling ID for this enhanced uplink beam selection protocol purpose.
