`ABSTRACT
`
`Systems and methods of determining transmitter and
`receiver configurations for a wireless device are provided. In
`one exemplary embodiment, a method performed by a
`wireless device (105, 200, 300a-b, 500, 605) in a wireless
`communications system (100) comprises transmitting or
`receiving ( 403) a first signal of a first type (113) using a first
`transmitter or receiver configuration based on a first quasi
`co-location (QCL) assumption (121) associating the first
`signal with a first reference signal (111) received by the
`wireless device. Further, the method includes transmitting or
`receiving ( 407) a second signal of a second type (117) using
`a second transmitter or receiver configuration based on a
`second QCL assumption (123) associating the second signal
`with a second reference signal (115) received by the wireless
`device.

`
`SYSTEMS AND METHODS FOR
`DETERMINING TRANSMITTER AND
`RECEIVER CONFIGURATIONS FOR A
`WIRELESS DEVICE
`
`FIELD OF DISCLOSURE
`
`[0001] The present disclosure relates generally to the field
`of communications, and in particular to determining trans(cid:173)
`mitter and receiver configurations for a wireless device.
`
`BACKGROUND
`
`In 5th Generation mobile networks or wireless
`[0002]
`systems (5G) or 5G New Radio (NR), spatial quasi co(cid:173)
`location (QCL) has been introduced as a new concept. Two
`transmitted reference signals from a transmitter ( e.g., base
`station) are said to be spatially QCL at a receiver (e.g., UE
`or terminal) if the receiving spatial characteristics of the two
`received reference signals are the same or similar. Spatial
`characteristics may be one or more of the primary angle of
`arrival, the receiving angular spread of the signal, the spatial
`correlation, or any other parameter or definition that captures
`spatial characteristics. The two reference signals are some(cid:173)
`times denoted equivalently as being transmitted/received
`from/by two different antenna ports. If two transmitting
`antenna ports of a gNB ( e.g., base station) are spatially QCL
`at the UE, the UE may use the same receiving (RX)
`beamforming weights to receive both the first and second
`reference signals.
`[0003] The use of spatial QCL is of particular importance
`when the UE uses analog beamforming, since the UE has to
`know where to direct the analog beam before receiving the
`signal. Hence, for 5G NR, it is possible to signal from gNB
`to UE that a certain previously transmitted channel state
`information reference signal (CSI-RS) resource or CSI-RS
`antenna port is spatially QCL with a physical downlink
`shared channel (PDSCH) transmission and the PDSCH's
`demodulation reference signal (DMRS) transmission. With
`this information, the UE may use the same analog beam for
`the PDSCH reception as it used in the reception of the
`previous CSI-RS resource or antenna port.
`[0004] The spatial QCL framework may also be extended
`to hold for transmissions from the UE. In this case, the
`transmitted signal from the UE is spatially QCL with a
`previous reception of a signal received by the UE. If the UE
`makes this assumption for the transmission, it means that the
`UE is transmitting back a signal in an analog transmit (TX)
`beam which is the same or similar to the RX beam previ(cid:173)
`ously used to receive a signal. Hence, the first Reference
`Signal (RS) transmitted from the gNB is spatially QCL at the
`UE with a second RS transmitted from the UE back to the
`gNB. This is useful in case the gNB uses analog beamform(cid:173)
`ing since the gNB then knows from which direction to
`expect a transmission from the UE and may therefore adjust
`its beam direction just before the actual reception.
`In 5G NR, a primary synchronization signal (PSS),
`[0005]
`a secondary synchronization signal (SSS), a physical broad(cid:173)
`cast channel (PBCH), and possibly a tertiary synchroniza(cid:173)
`tion signal (TSS) will be used in a synchronization signal
`(SS) block. The SS block will likely span four orthogonal
`frequency division multiplex (OFDM) symbols. Multiples
`of such SS blocks may be transmitted on different beams in
`different beamforming directions, and thus each SS block
`may benefit from the antenna gain of the corresponding
`
`beam. The drawback is that multiple SS blocks require
`multiples of four OFDM symbols to be used to cover the
`whole gNB area with such beams. Further, the narrower the
`beam, the better the coverage per beam but the larger the
`overhead from transmitting SS blocks. Hence, there is a
`tradeoff between coverage and overhead. Also, SS block
`beams are wider than data beams, which may be very narrow
`to provide very high antenna gain in order to maximize the
`signal to interference plus noise ratio (SINR) at the receiver.
`[0006] Furthermore, existing air interface solutions do not
`provide robust communications between a UE and a gNB
`when utilizing narrow beamforming such as in the millime(cid:173)
`ter wave frequencies. This is even more apparent with
`analog beamforming that requires knowing where to direct
`a beam. Since beams are very narrow ( e.g., down to a few
`degrees in beam width) failure to direct this narrow beam in
`the right direction may lead to loss in connection and
`interruption in data throughput. Also, the UE may need to
`direct the beam in a robust manner when receiving synchro(cid:173)
`nization signals and broadcast signals ( e.g., common search
`space physical downlink control channel (PDCCH)) or
`transmitting physical random access channel (PRACH) or
`beam recovery signals while at the same time receiving and
`transmitting dedicated signals that require high gain or
`narrow beams ( e.g., PDSCH, physical uplink shared channel
`(PUSCH), and VE-specific search space PDCCH). In addi(cid:173)
`tion, the UE may need to set the UE beam direction without
`dedicated beam indication signaling from gNB to UE. In an
`NR system, there is also a need to transmit both narrow and
`wide width beams, where narrow beams may be used for the
`transmission of unicast messages while wide beams may be
`used for the transmission of multicast or broadcast mes(cid:173)
`sages.
`[0007] Accordingly, there is a need for improved tech(cid:173)
`niques for determining transmitter and receiver configura(cid:173)
`tions for a wireless device. In addition, other desirable
`features and characteristics of the present disclosure will
`become apparent from the subsequent detailed description
`and embodiments, taken in conjunction with the accompa(cid:173)
`nying figures and the foregoing technical field and back(cid:173)
`ground.
`[0008] The Background section of this document is pro(cid:173)
`vided to place embodiments of the present disclosure in
`technological and operational context, to assist those of skill
`in the art in understanding their scope and utility. Unless
`explicitly identified as such, no statement herein is admitted
`to be prior art merely by its inclusion in the Background
`section.
`
`SUMMARY
`
`[0009] The following presents a simplified summary of the
`disclosure in order to provide a basic understanding to those
`of skill in the art. This summary is not an extensive overview
`of the disclosure and is not intended to identify key/critical
`elements of embodiments of the disclosure or to delineate
`the scope of the disclosure. The sole purpose of this sum(cid:173)
`mary is to present some concepts disclosed herein in a
`simplified form as a prelude to the more detailed description
`that is presented later.
`[0010] Systems and method of determining transmitter
`and receiver configurations for a wireless device are pre(cid:173)
`sented herein. According to one aspect, a method performed
`by a wireless device in a wireless communications system
`comprises transmitting or receiving, by the wireless device,

`
`a first signal of a first type using a first transmitter or receiver
`configuration based on a first QCL assumption associating
`the first signal with a first reference signal received by the
`wireless device. Further, the method includes transmitting or
`receiving, by the wireless device, a second signal of a second
`type using a second transmitter or receiver configuration
`based on a second QCL assumption associating the second
`signal with a second reference signal received by the wire(cid:173)
`less device.
`[0011] According to another aspect, the first reference
`signal is a broadcasted reference signal and the second
