Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may measure a reference signal received power (RSRP) associated with a reference signal (RS) broadcast by a network. The UE may further measure a received signal strength indicator (RSSI) using a plurality of resource elements (REs) that do not include the RS and excluding REs that do include the RS. Accordingly, the UE may determine a reference signal received quality (RSRQ) associated with the RS based at least in part on the RSRP and the RSSI. Numerous other aspects are described.

Reference signal received quality for fully loaded reference signals

Methods, systems, and devices for wireless communications are described. A wireless device may receive a transmission including a set of spatial layers. The set of spatial layers may include at least a first spatial layer and a second spatial layer subsequent to the first spatial layer. The device may determine a first number of search points of the first spatial layer based on a modulation order of the first spatial layer, and a second number of search points of the second spatial layer based on the first number of search points and a modulation order of the second spatial layer. The device may compute a quantity of distance metrics based on the first and second numbers of search points. The device may demap symbols of the received transmission based on the quantity of distance metrics. In some examples, demapping the symbols may be based on a per-stream recursive demapping process.

Enhanced per-stream recursive demapping techniques

Methods, systems, and devices for wireless communications are described. A wireless communication system may support techniques for correlation-based hardware sequences for layered decoding. In some cases, a user equipment (UE) may partition layers of a submatrix associated with a parity check decoding procedure into a first set of layers and a second set of layers. The UE may sort each set of layers into a respective set of layer orders (e.g., a first set of layer orders and a second set of layer orders) based on an associated set of correlation values. The UE may combine the first set of layer orders and the second set of layer orders to obtain a set of combined layer orders and may select a decoding schedule from a set of decoding schedules used for decoding each of the combined layer orders based on respective schedule lengths for the set of decoding schedules.
