Signal reception

An apparatus comprising:

• at least one processor;
• and
• at least one memory storing instructions that when executed by the at least one processor cause the apparatus at least to perform:
• receiving signals, from a network node, across a frequency range in a first mode, the frequency range containing at least two non-contiguous frequency blocks containing wanted signals for receiving signals transmitted by the network node, the at least two non-contiguous frequency blocks being separated by at least one frequency block in which unwanted signals to the apparatus may be transmitted;
• the apparatus being configured in the first mode to use at least two receive branches configured to receive signals across the first frequency range;
• receiving signals, from the network node, across the frequency range in a second mode;
• the apparatus being configured in the second mode to use one receive branch of the at least two receive branches to receive a first frequency block of the at least two non-contiguous frequency blocks containing a wanted signal and suppress reception of a signal in the at least one frequency block in which unwanted signals to the apparatus may be transmitted;
• and another of the receive branches of at least two receive branches to receive a different frequency block of the at least two non-contiguous frequency blocks containing a wanted signal and suppress reception of a signal in the at least one frequency block in which unwanted signals to the apparatus may be transmitted;
• determining an indication that the apparatus is to change between the first mode and the second mode;
• and
• adjusting the apparatus between the first mode and the second mode in response to determining the indication that the apparatus is to change between modes.

A method performed by user equipment, the method comprising:

• receiving signals, from a network node at a user equipment, across a frequency range in a first mode, the frequency range containing at least two non-contiguous frequency blocks for receiving signals transmitted by the network node, the at least two non-contiguous frequency blocks being separated by at least one frequency block in which unwanted signals may be transmitted;
• the user equipment being configured in the first mode to use at least two receive branches configured to receive signals across the first frequency range;
• receiving signals, from the network node at the user equipment, across the frequency range in a second mode;
• the user equipment being configured in the second mode to use one receive branch of the at least two receive branches to receive a first frequency block of the at least two non-contiguous frequency blocks and suppress reception of a signal in the at least one frequency block in which unwanted signals may be transmitted;
• and another of the receive branches of at least two receive branches to receive a different frequency block of the at least two non-contiguous frequency blocks and suppress reception of a signal in the at least one frequency block in which unwanted signals may be transmitted;
• determining an indication that the user equipment is to change between the first mode and the second mode;
• and
• adjusting the user equipment between the first mode and the second mode in response to determining the indication that the user equipment is to change between the first mode and the second mode.

A non-transitory computer readable medium storing instructions which, when executed by an apparatus, cause the apparatus to perform at least the following:

• receiving signals, from a network node, across a frequency range in a first mode, the frequency range containing at least two non-contiguous frequency blocks for receiving signals transmitted by the network node, the at least two non-contiguous frequency blocks being separated by at least one frequency block in which unwanted signals may be transmitted;
• the apparatus being configured in the first mode to use at least two receive branches configured to receive signals across the first frequency range;
• receiving signals, from the network node, across the frequency range in a second mode;
• the apparatus being configured in the second mode to use one receive branch of the at least two receive branches to receive a first frequency block of the at least two non-contiguous frequency blocks and suppress reception of a signal in the at least one frequency block in which unwanted signals may be transmitted;
• and another of the receive branches of at least two receive branches to receive a different frequency block of the at least two non-contiguous frequency blocks and suppress reception of a signal in the at least one frequency block in which unwanted signals may be transmitted;
• determining an indication that the apparatus is to change between the first mode and the second mode;
• and
• adjusting the apparatus between the first mode and the second mode in response to determining the indication that the apparatus is to change between the first mode and the second mode.
