This application relates generally to wireless communication systems, including uplink transmissions to multiple transmission reception points (multi-TRPs).
Wireless mobile communication technology uses various standards and protocols to transmit data between a base station and a wireless mobile device. Wireless communication system standards and protocols can include the 3rd Generation Partnership Project (3GPP) long term evolution (LTE) (e.g., 4G) or new radio (NR) (e.g., 5G); the Institute of Electrical and Electronics Engineers (IEEE) 802.16 standard, which is commonly known to industry groups as worldwide interoperability for microwave access (WiMAX); and the IEEE 802.11 standard for wireless local area networks (WLAN), which is commonly known to industry groups as Wi-Fi. In 3GPP radio access networks (RANs) in LTE systems, the base station can include a RAN Node such as a Evolved Universal Terrestrial Radio Access Network (E-UTRAN) Node B (also commonly denoted as evolved Node B, enhanced Node B, eNodeB, or eNB) and/or Radio Network Controller (RNC) in an E-UTRAN, which communicate with a wireless communication device, known as user equipment (UE). In fifth generation (5G) wireless RANs, RAN Nodes can include a 5G Node, NR node (also referred to as a next generation Node B or g Node B (gNB)).
RANs use a radio access technology (RAT) to communicate between the RAN Node and UE. RANs can include global system for mobile communications (GSM), enhanced data rates for GSM evolution (EDGE) RAN (GERAN), Universal Terrestrial Radio Access Network (UTRAN), and/or E-UTRAN, which provide access to communication services through a core network. Each of the RANs operates according to a specific 3GPP RAT. For example, the GERAN implements GSM and/or EDGE RAT, the UTRAN implements universal mobile telecommunication system (UMTS) RAT or other 3GPP RAT, the E-UTRAN implements LTE RAT, and NG-RAN implements 5G RAT. In certain deployments, the E-UTRAN may also implement 5G RAT.
To easily identify the discussion of any particular element or act, the most significant digit or digits in a reference number refer to the figure number in which that element is first introduced.
Various embodiments are described with regard to a UE. However, reference to a UE is merely provided for illustrative purposes. The example embodiments may be utilized with any electronic component that may establish a connection to a wireless network and is configured with the hardware, software, and/or firmware to exchange information and data with the wireless network. Therefore, the UE as described herein is used to represent any appropriate electronic component.
To improve reliability, certain systems with further enhanced multiple-input-multiple-output (FeMIMO) may include enhancements to physical downlink control channel (PDCCH), physical uplink control channel (PUCCH), and physical uplink shared channel (PUSCH) with multiple transmission reception point (multi-TRP) transmission. One of the potential enhancements is PUCCH and/or PUSCH repetition with different transmit (TX) beams. Embodiments disclosed herein provide enhancements to support repetition based multi-TRP uplink (UL) transmission. Certain embodiments, for example, define criteria to enable UL repetition transmission with multiple beams. In addition, or in other embodiments, coordination is provided between a wireless network and a UE to improve UL time division multiplexed (TDMed) transmissions when a UE switches between antenna panels.
Regardless of the scheme used (e.g, cyclic mapping or sequential mapping), multi-TRP UL TDMed transmission with repetition is introduced to enhance reliability. A wireless network may configure a UE in a connected state to perform measurements and report the measurement results according to a measurement configuration. The measurement configuration may be provided by dedicated signaling. The measurement configuration may define, for example, measurement objects, reporting configurations, measurement gaps, and other parameters. For each measurement type (e.g., intra-frequency, inter-frequency, and inter-RAT), the measurement configuration may define one or more measurement object (MO). In NR, each MO may indicate frequency, timing, and subcarrier spacing of reference signals to be measured. When configured by the wireless network, the UE may be able to perform Layer 1 reference signal received power (L1-RSRP) and/or Layer 1 signal-to-noise and interference ratio (L1-SINR) measurements of downlink (DL) reference signals, such as a synchronization signal blocks (SSB), a channel state information reference signal (CSI-RS), or both. Skilled persons will recognize from the disclosure herein that Layer 1 refers to the physical (PHY) layer of the protocol stack.
For example,
Measuring the DL RSs provides channel condition or beam condition information that may be associated with corresponding UL transmission beams from the UE to the different TRPs. The wireless network may use the reported L1-RSRP and/or L1-SINR to enable multi-TRP UL TDMed transmission, as shown in
For the beam measurement based criteria, according to one embodiment, the wireless network enables UL repetition transmission with multiple beams when the UL beams are known to the UE. The UE monitors, measures, and reports L1-RSRP and/or L1-SINR for the DL RSs associated with UL transmission beams to multi-TRP. Based on the measurement reports from the UE, the wireless network may determine that the UL beams are known to the UE. Based on this information, the wireless network may enable the UE to use the known UL beams for multi-TRP UL TDMed transmission. In certain such embodiments, the wireless network determines that the reported beam information is not outdated before enabling the multi-TRP UL TDMed transmission scheme. For example, the UE may determine that the beam measurements and reporting were made within a last X milliseconds (ms).
For the L1-RSRP/L1-SINR based criteria, according to one embodiment, the wireless network enables UL repetition transmission with multiple beams when an absolute L1-RSRP and/or L1-SINR measured value is below a predetermined threshold that warrants the repetitions so as to provide reliability enhancement of the UL transmissions. In other words, if the beam quality is such that the L1-RSRP and/or L1-SINR measured value is above the predetermined threshold, the wireless network may determine that a UL transmission does not need to be repeated to multi-TRP to enhance reliability. In addition, in certain embodiments, the wireless network determines that the L1-RSRP and/or L1-SINR measured values for the DL RSs associated with the different UL beams are comparable to one another in order for the repetition scheme to be successful. The wireless network may, for example, enable UL repetition transmission with multiple beams when a difference (i.e., delta) between the L1-RSRP and/or L1-SINR of the DL RSs associated with the different UL beams is within a range of 0 to Y dB.
For the time based criteria, the wireless network may enable UL repetition transmission with multiple beams when a total number of repetitions for a PUCCH or PUSCH is within a certain time such that the UE TX beams do not become outdated (e.g., due to movement or rotation of the UE). For example, if the number of repetitions extend over sixteen slots then wireless network may determine that the UL beams may become outdated before the repetitions can be transmitted. Thus, in certain embodiments, the wireless network enables UL repetition transmission with multiple beams when the repetitions are within a certain time such that the conditions (e.g., channel conditions, L1-RSRP/L1-SINR measurements) do not substantially change.
During a UL beam switch, the UE might switch between beams within the same panel or a different panel. In case of intra-panel beam switching, the switching time may be within a cyclic prefix (CP) length. However, in case of inter-panel beam switching, the switching time may be longer than the CP, if both panels are not already activated. When both antenna panels are not activated, additional panel activation time needs to be considered for beam switching. The UE might choose to de-activate antenna panels, for example, when not in use to reduce power consumption. Panel activation and/or de-activation may cause additional interruption on other active component carriers (CCs).
If the wireless network is unaware of the antenna panel(s) used for reception of the DL RSs and transmission of the UL beams, then the wireless network is unaware of whether additional time is used by the UE for beam switching due to switching between different antenna panels.
Thus, in one embodiment, the UE provides an indication of the antenna panel along with the corresponding L1-RSRP and/or L1-SINR measurement. The indication enables the wireless network to determine the switching time needed for UL TDMed transmissions based on the antenna panel indicated for the corresponding measurements. The wireless network may also account for resource allocation based on transmission gaps to accommodate UE beam switching.
In another embodiment, the UE dynamically indicates a time for beam switching for a scheduled UL transmission with repetition based on DL RSs associated with the UL beams. The wireless network may allocate resources and switching gap according to the UE indication.
In another embodiment, a short activation period is used during which both panels involved in switching from a first beam to a second beam are activated. Thus, the UE can switch UL beams without a long delay. In certain such embodiments, the activation period contains all repetitions and is limited in time to avoid extra UE power consumption. Using the short activation period helps avoid long gaps for beam switching and interruptions due to activation and/or de-activation of the antenna panels. The UE may indicate, based on its capability of multi-panel support, whether the UE supports or can benefit from a short period where both antenna panels involved in the beam switch are active. The wireless network may then schedule the active period for UE and schedules the UL TDMed repetition transmissions.
In certain embodiments, the wireless network schedules repetition based UL transmission with a long enough time (e.g., K2) between a PDCCH scheduling a PUSCH and an actual transmission of the PUSCH from the UE, such that the UE can activate antenna panels and prepare for UL transmission without large gaps between transmissions. When combined with embodiments using the short activation period discussed above, K2 is selected so as to be long enough for the UE to prepare for UL transmission without the need for extra time and/or gaps for antenna panel activation.
