Control resource set information in physical broadcast channel
Described is an apparatus of a User Equipment (UE) operable to communicate with a fifth-generation Evolved Node-B (gNB) on a wireless network. The apparatus may comprise a first circuitry and a second circuitry. The first circuitry may be operable to process a message comprising an indicator to indicate a number of contention based physical random access channel (PRACH) preambles within a PRACH occasion per Synchronization Signal Block (SSB). The second circuitry may be operable to generate a first PRACH occasion, based on the indicator.
1. A User Equipment (UE) operable to communicate with a base station on a wireless network, comprising:
one or more processors to:
process a system message carrying a system indicator to indicate a total number of physical random access channel (PRACH) preambles for a PRACH occasion associated with a Synchronization Signal Block (SSB);
process a message carrying an indicator having a value selected from a set consisting of 1, 2, 3, and 4 to indicate a first number of contention-based PRACH preambles within the PRACH occasion, wherein the PRACH occasion includes a second number of contention free PRACH preambles, wherein the second number is a difference between the total number and the first number, and wherein the system message is different from the message; and
generate a first PRACH occasion, based on the indicator; and
an interface for sending the first PRACH occasion to a transmission circuitry.
2. The UE of claim 1 , wherein:
the indicator is a first indicator, and
the message carries a second indicator comprising a second integer to indicate a number of SSBs per PRACH occasion.
3. The UE of claim 2 , wherein an upper limit of the second indicator is based on the first indicator.
4. The UE of claim 1 , wherein:
the indicator is a first indicator; and
the message carries one or more second indicators comprising one or more corresponding second integers to indicate a number of PRACH preambles within the PRACH occasion associated with the SSB.
5. The UE of claim 4 , wherein an upper limit of the one or more second indicators are based on the first indicator.
6. The UE of claim 1 , wherein 4 PRACH preambles within the PRACH occasion are associated with the SSB.
7. The UE of claim 1 , comprising an application processor, a memory, one or more antennas, a wireless interface for allowing the application processor to communicate with another device, and a touch-screen display.
8. A non-transitory computer readable medium having machine executable instructions that, when executed, cause one or more processors of a User Equipment (UE) operable to communicate with a base station on a wireless network to perform an operation, the operation comprising:
processing a system message carrying a system indicator to indicate a total number of physical random access channel (PRACH) preambles for a PRACH occasion associated with a Synchronization Signal Block (SSB);
processing a message carrying an indicator having a value selected from a set consisting of 1, 2, 3, and 4 to indicate a first number of contention-based PRACH preambles within the PRACH occasion, wherein the PRACH occasion includes a second number of contention free PRACH preambles, wherein the second number is a difference between the total number and the first number, and wherein the system message is different from the message; and
generating a first PRACH occasion, based on the indicator.
9. The non-transitory computer readable medium of claim 8 , wherein:
the indicator is a first indicator;
the message carries a second indicator that is a second integer to indicate a number of SSBs per PRACH occasion; and
an upper limit of the second indicator is based on the first indicator.
10. A User Equipment (UE) operable to communicate with a base station on a wireless network, comprising:
one or more processors to:
generate a Channel State Information (CSI) report comprising a CSI part 1 of the CSI report and a CSI part 2 of the CSI report, and
generate a Physical Uplink Shared Channel (PUSCH) transmission comprising a plurality of symbols, wherein the CSI part 1 is embedded starting from a first symbol of the PUSCH transmission, and the CSI part 2 is mapped to a symbol transmitted in a Phase Tracking Reference Signal (PT-RS) of the PUSCH transmission, wherein the CSI part 2 is separated from the CSI part 1 ; and
an interface for sending the PUSCH transmission to a transmission circuitry.
11. The UE of claim 10 , wherein the one or more processors are to:
generate the PUSCH transmission such that a Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK) is embedded within the PUSCH transmission for transmission subsequent to a transmission of a Demodulation Reference Signal (DM-RS) symbol associated with the PUSCH transmission.
12. The UE of claim 10 , wherein the PUSCH transmission includes a Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK) that is mapped in the symbol including the PT-RS or mapped around the PT-RS.
13. The UE of claim 12 , wherein the HARQ-ACK and the CSI part 1 or the CSI part 2 are mapped to an antenna port that is quasi-co-location (QCL) with an antenna port of the PT-RS.
14. The UE of claim 12 , wherein the HARQ-ACK, the CSI part 1 or the CSI part 2 are located in resource elements (REs) with different comb offsets.
15. The UE of claim 12 , wherein a comb distance for the HARQ-ACK, the CSI part 1 , the CSI part 2 , and uplink data are configured by higher layers.
16. The UE of claim 10 , wherein the CSI part 1 , the CSI part 1 , and uplink data are interleaved in frequency with equal comb distance.
