Abstract
Methods, systems, and devices for multi-beam power control and detecting link recovery confirmation information are described. An exemplary method for wireless communication includes determining an association between a set of parameters and a plurality of beams; and performing, by a terminal and based on the association, one or more uplink transmissions, where the set of parameters comprises at least one of the following parameters: one or more open loop parameters, one or more closed loop parameters, one or more transmit power control (TPC) commands or one or more path loss reference signal (PL-RS) parameters.
Claims12
A method of wireless communication, comprising:
- detecting a link recovery confirmation information;
- and
- initializing, subsequent to the detecting, a closed loop power control of a physical uplink control channel (PUCCH) transmission to a sum of a ramp-up power and a transmit power control (TPC) power offset,
- wherein the detecting the link recovery confirmation information comprises detecting a downlink control information (DCI) format comprising a cyclic redundancy check (CRC) scrambled by a cell radio-network temporary identifier (C-RNTI) or a modulation and coding scheme (MCS)C-RNTI in a search space set, and
- wherein the initializing the closed power loop of the PUCCH transmission comprise initializing the closed loop power control of the PUCCH transmission after K symbols from a last symbol of a first physical downlink control channel (PDCCH) reception in the search space set for which a user device detects the DCI format with CRC scrambled by C-RNTI or MCS-C-RNTI.
An apparatus for wireless communication, comprising:
- a processor configured to:
- detect a link recovery confirmation information;
- and
- initialize, subsequent to the detecting, a closed loop power control of a physical uplink control channel (PUCCH) transmission to a sum of a ramp-up power and a transmit power control (TPC) power offset,
- wherein the processor is further configured to detect the link recovery confirmation information by detecting a downlink control information (DCI) format comprising a cyclic redundancy check (CRC) scrambled by a cell radio-network temporary identifier (C-RNTI) or a modulation and coding scheme (MCS)C-RNTI in a search space set, and
- wherein the processor is further configured to initialize the closed loop power control of the PUCCH transmission, after K symbols from a last symbol of a first physical downlink control channel (PDCCH) reception in the search space set for which the apparatus detects the DCI format with CRC scrambled by C-RNTI or MCS-C-RNTI.
A non-transitory computer-readable storage medium having instructions stored thereupon for wireless communication, comprising:
- instructions for detecting a link recovery confirmation information;
- and
- instructions for initializing, subsequent to the detecting, a closed loop power control of a physical uplink control channel (PUCCH) transmission to a sum of a ramp-up power and a transmit power control (TPC) power offset,
- wherein the instructions for detecting the link recovery confirmation information comprises instructions for detecting a downlink control information (DCI) format comprising a cyclic redundancy check (CRC) scrambled by a cell radio-network temporary identifier (C-RNTI) or a modulation and coding scheme (MCS)C-RNTI in a search space set, and
- wherein the instructions for initializing the closed power loop of the PUCCH transmission comprise instructions for initializing the closed loop power control of the PUCCH transmission after K symbols from a last symbol of a first physical downlink control channel (PDCCH) reception in the search space set for which a user device detects the DCI format with CRC scrambled by C-RNTI or MCS-C-RNTI.
