Abstract: PROBLEM TO BE SOLVED: To perform AGC and DC compensation in a receiver.SOLUTION: A receiver comprises: an energy estimator for generating an estimate of the level of a received signal; an RF device to apply gain to the received signal; an AGC for controlling the RF device gain on the basis of the energy estimate; a first DC compensation loop for finely adjusting DC compensation of the received signal in a fast or slow tracking mode (FTM or STM); and a second DC compensation loop for coarsely adjusting a DC component of the received signal. AGC operations have three modes, namely, in acquisition, in connection, and in sleep.

Abstract: A method for selecting an antenna is described. The method includes transmitting using a first antenna with a first metric and a radio frequency (RF) chain for a first dwelling period. The method includes switching to transmitting using a second antenna with a second metric for a first testing period. The second antenna uses the same RF chain as the first antenna. The first metric is compared with the second metric to determine an optimal antenna. The optimal antenna is selected.

Abstract: A technique for performing AGC and DC compensation in a receiver. The receiver comprises an energy estimator for generating an estimate of the level of a received signal; an RF device to apply gain to the received signal; an AGC for controlling the RF device gain based on the energy estimation; a first DC compensation loop for finely adjusting the DC component of the received signal in fast or slow tracking mode (FTM or STM); and a second DC compensation loop for coarsely adjusting the DC component of the received signal. Three modes of AGC operations: In Acquisition, iterations of FTM fine DC adjustment, short energy estimation, and RF device gain adjustment are performed during signal timing detection. In Connected, long energy estimation, RF device gain adjustment, and STM fine and coarse DC adjustments are performed during superframe preamble. In Sleep, FTM fine DC adjustment, short energy estimation, and RF device gain adjustment are performed during superframe preamble.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for providing beam switch latency using communications systems operating according to new radio (NR) technologies. For example, the method generally includes determining a latency associated with a beam switch from a source antenna array module to a target antenna array module when the target module is in a low power mode; and signaling a base station to use the determined latency after sending a command for the beam switch.
